[0139] The electrical wire entering through the first slip ring input 418 can be placed in electrical communication with one or more first slip ring lugs 420 that can serve as secure a connection point for establishing electrical contact throughout the first slip ring assembly 410. Each first slip ring lug 420 can be configured to receive and secure an electrical wire from the cabin 208, creating multiple independent electrical circuits that can handle different power requirements and signal types. The first slip ring lugs 420 can be constructed from conductive materials that can maintain reliable electrical connectivity while accommodating the rotational movements and environmental stresses encountered during operation of the articulated machine. The slip ring lugs 420 can be arranged to provide organized wire management and can include fastening mechanism (not shown) that can ensure secure electrical connections are maintained throughout the operational life of the power swivel system.
[0140] Each first slip ring lug 420 can be placed in electrical communication with a first conductive ring 424 that can serve as a rotating electrical conductor within the first slip ring assembly 410. The first conductive ring 424 can be constructed from highly conductive materials such as copper or specialized conductive alloys, for example, which can maintain excellent electrical conductivity while providing durability and resistance to wear from continuous rotational contact. Each first conductive ring 424 can be configured to handle specific electrical requirements such as DC power transmission, control signal distribution, or communication data transfer, enabling multiple independent electrical circuits to operate simultaneously within the first slip ring assembly. Each first conductive ring 424 can be mounted within the first slip ring assembly 410 using a fastening method that can maintain proper alignment and spacing while allowing for smooth rotational movement.
[0141] Each first conductive ring 424 can be placed in electrical communication with a first brush 426 that can provide sliding electrical contact between the rotating first conductive ring 424 and stationary electrical connections within the first slip ring assembly 410. The first brush 426 can be constructed from carbon or other specialized conductive materials that can maintain reliable electrical contact while minimizing friction and wear during continuous rotation operations. Each brush 426 can be spring-loaded or otherwise biased to maintain consistent contact pressure against its corresponding conductive ring, ensuring reliable electrical connectivity throughout the full range of rotational movement. The first slip ring assembly 410 can include multiple brushes 426 for each first conductive ring 424 to provide redundancy and ensure that electrical connectivity is maintained even if individual brushes 426 experience wear or temporary loss of contact. The brushes 426 can be configured to accommodate the rotational speeds and environmental conditions encountered during power swivel system operation while maintaining consistent electrical performance.
[0142] The brushes 426 can be placed in electrical communication with a first slip ring 428 that can sit interior to the first slip ring assembly 410 and can complete the electrical connection within the rotating first slip ring assembly 410. The first slip ring 428 can be constructed as a conductive element that can rotate independently from the exterior components of the first slip ring assembly 410 while maintaining electrical connectivity through the first brush 426 interface. Each first slip ring 428 can be configured to handle specific electrical circuits and can be isolated from adjacent slip rings 428 to militate against electrical crosstalk or interference between different electrical systems. The first slip ring 428 can be mounted on a bearing or similar rotation mechanism that can enable smooth, continuous rotation while maintaining proper electrical contact through the brush 426 system.
[0143] The first slip rings 428 within the first slip ring assembly 410 can be connected to a first rod 430 that can be disposed within the core 402 and can provide structural mounting and electrical connectivity throughout the dual power swivel system 400. The first rod 430 can serve as both a mechanical support element and an electrical conductor that can transmit electrical power and information from the first slip ring assembly 410 through the core 402 to the electrical hub 416. The first rod 430 can be constructed from a conductive material that can maintain electrical connectivity while providing adequate structural strength to support the components of the first slip ring assembly 410 during rotational operations. The first rod 430 can be configured to interface with the electrical conduit system within the core 402, enabling electrical connections to be routed from the first slip ring assembly 410 to the electrical hub 416.
[0144] The electrical hub 416 can include a first electrical ring 432 in electrical communication with the first rod 430. The first electrical ring 432 can also include one or more first electrical ring lugs 434, with each first electrical ring lungs 434 in electrical communication with an electrical wire 435. The electrical wire 435 can bundle into an opening of the electrical hub 416 and feed down through the core 402 from a first end 438 of the core 402 to a second end 440 of the core 402. The electrical wires 435 can exit the core 402 at the second end 440.
[0145] In sum, electrical power can flow through the first portion 404 by placing the electrical wire 435 from the cabin 208 in electrical communication with the first slip ring assembly 410, which can be in electrical communication with the first rod 430. The first rod 430 can, in turn, be placed in electrical communication with the electrical hub 416 which can run electrical power to the wires 435 connected to the one or more first electrical ring lugs 434. These wires 435 can be run into the electrical hub 416, as shown in
[0146] Turning now to
[0147] The second portion 406 of the dual power swivel system 400 can be configured to provide electrical power distribution to the boom apparatus 210 through the second slip ring assembly 442 that can operate substantially in accordance with the same electrical transmission principles as the first slip ring assembly 410 while maintaining independent rotational capabilities. The second slip ring assembly 442 can be engineered to receive electrical power from an external power source through a second slip ring input 445, which can serve as the primary electrical entry point for power distribution to the boom apparatus and associated hydraulic and mechanical systems.
[0148] The second slip ring assembly 442 can include a plurality of interconnected electrical components that can work in coordinated fashion to maintain continuous electrical connectivity while permitting unlimited rotational movement of the second portion relative to the core 402 and other components of the dual power swivel system 400. The components can include one or more second slip ring lugs 447 that can be configured to receive incoming electrical wires 435 from the power source, a second conductive ring 448 that can be electrically coupled to the second slip ring lugs 447 through soldered connections to ensure electrical continuity, a second brush assembly comprising one or more carbon brushes 450 that can maintain physical contact with rotating electrical components, a second slip ring 452 that can rotate independently while maintaining electrical contact through the brush assembly, and a second rod 454 that can be electrically connected to the second slip ring 452 through silver soldering or other suitable electrical joining methods to ensure optimal current transmission.
[0149] The electrical pathway through the second slip ring assembly 442 can begin with electrical wires 435 entering from the power source through the second slip ring input 445, where the electrical current can flow through the second slip ring lugs 447, which can be electrically connected to the second conductive ring 448 through soldered joints that can provide permanent electrical connections capable of handling the required electrical loads for boom apparatus 210 operation. The second conductive ring 448 can be electrically coupled to the second brush 450.
[0150] The second brush 450 can conduct electrical current to the second slip ring 452, which can be configured as a brass or other conductive metal ring that can rotate independently from the surrounding assembly components while maintaining electrical connectivity through the brush 450 contact interface. The second slip ring 452 can include a second rod 454 that can be coupled through silver soldering or equivalent high-conductivity joining methods, with the second rod 454 extending upward to connect with one or more second electrical ring lugs 456 on a second electrical ring 458 that can serve as the output terminals for the electrical current while the assembly maintains rotational capabilities.
[0151] The electrical routing configuration of the second slip ring assembly 442 can differ from the first slip ring assembly 410 in that the electrical wires 435 emerging from the second electrical ring lugs 456 do not proceed to the electrical hub 416 as occurs in the first slip ring assembly 410, but instead can exit the second slip ring assembly 442 through a second slip ring output 460 that can provide a controlled exit point for the electrical conductors. The electrical wires 435 can then reenter the second portion 406 through the first jug 444, which can serve as an intermediate routing component to accommodate the electrical conductors while maintaining the structural integrity and rotational capabilities of the second portion 406.
[0152] Upon entering the first jug 444, the electrical wire 435 can be routed through an internal pathway (not shown) that can be configured to accommodate the electrical conductors while militating against interference with hydraulic fluid pathways and mechanical components. The electrical wires 435 can exit the first jug 444 through the support manifold 446, which can serve as both a mechanical coupling component and an electrical routing interface between the second portion 406 and the boom apparatus 210. The support manifold 446 can include a passage or conduit that can allow the electrical wires 435 to pass through while maintaining appropriate sealing and protection from environmental factors and mechanical damage.
[0153] The electrical pathway can culminate with the wires 435 emerging from the support manifold 446 to provide electrical power directly to the boom apparatus 210, enabling operation of various electrical and electro-hydraulic components associated with the boom apparatus 210, including a hydraulically operated actuator with an electrical control system, an electrical valve assembly, a lighting system, a sensor array, a control interface, and other electrical equipment that can be integrated with the boom apparatus 210 for enhanced operational capabilities and control.
[0154] Turning now to the hydraulic power mechanism of the second portion 406, the second portion 406 can utilize hydraulic power for providing power to the boom apparatus 210. The second portion 406 can include the first jug 444 through which the boom apparatus 210 can receive hydraulic fluid. The second portion 406 of the dual power swivel system 400 can be constructed from a durable material such as high-strength steel, stainless steel, aluminum alloys, brass, bronze, or other corrosion-resistant metals, for example, that can withstand high hydraulic pressure and provide reliability over the lifespan of the dual power swivel system 400, particularly in a demanding operational environment. A skilled artisan can select a suitable material for the second portion 406 based on the ability of the material to resist wear, corrosion, and hydraulic fluid compatibility, within the scope of the present disclosure.

[0156] With reference to
[0157] Each first ring 466 can include a hydraulic seal 470 that can be constructed from materials including nitrile rubber, fluorocarbon elastomers, polyurethane, or other specialized sealing compounds, for example. Each first ring 466 can include one or more hydraulic seals 470 that can militate against hydraulic fluid from exiting the first ring 466 and can provide rotary sealing action between the stationary core 402 and the rotating first jug 444. The hydraulic seal 470 can be positioned to isolate each first ring 466 individually and can maintain fluid pressure while militating against cross-contamination between different first rings 466. The hydraulic seal 470 can be configured to accommodate continuous rotation of the first jug 444 while maintaining sealing performance, with the rotary sealing action enabling the core 402 to remain stationary relative to the rotating various components of the first jug 444.
[0158] As described herein, the first rings 466 can include the internal hydraulic fluid channel 472 that can promote proper hydraulic fluid flow within the system 400. The channel 472 can include a smooth surface to minimize pressure loss and can incorporate a tapered entry to facilitate efficient hydraulic fluid movement. The hydraulic fluid channel 472 can be disposed within each first ring 466 to align with the corresponding port 462 and can create a continuous fluid pathway from the core 402 to a first jug output 474.
[0159] The first jug 444 can include one or more first jug outputs 474 that can include a one-way configuration to militate against hydraulic fluid backflow and maintain system 400 pressure. Each first jug output 474 can correspond to one of the first rings 466 in the first jug 444 and can be positioned to align with one hydraulic fluid channel 472 within the first ring 466. The first jug output 474 can include a threaded portion to accommodate a hydraulic fitting for using with the dual power swivel system 400 to deliver hydraulic fluid to the desired portion of the boom apparatus 210.
[0160] In operation, hydraulic fluid can travel through the core 402 via the port 462, into the first ring via the cross-drilled opening 468, through the hydraulic fluid channel 472 of the first ring 466 and out the first jug output 474 to provide hydraulic fluid to a portion of the boom apparatus 210. The one-way first jug output 474 can promote hydraulic fluid flow in the intended direction, with hydraulic fluid coming down the core 402 and ultimately exiting the dual power swivel system 400 into the boom apparatus 210. The hydraulic fluid flow can be controlled by the user via operation of the boom apparatus 210, with the operator control enabling management of hydraulic fluid distribution to various hydraulic circuits and actuators throughout the machine 200. It should be appreciated that the first jug outputs 474 can be evenly disposed about a portion of the circumference and the length of the first jug 444 to allow for 474 to be connected to the closest reasonable portion of the boom apparatus 210 that requires hydraulic fluid, optimizing hydraulic line routing and reducing system 400 complexity.
[0161] As shown in
[0162] The support manifold 446 can facilitate electrical wire 435 routing from the core 402 to the boom apparatus 210. Specifically, electrical wires 435 can be disposed within and substantially adjacent to an interior of the wall of the first jug 444 and can exit the second portion 406 through the support manifold 446, allowing the wires 435 to come out on the top of the boom apparatus 210 where the electrical wire 435 can be properly sealed. The electrical routing capability can enable the transmission of control signals, power, and communication lines to various electrical components mounted on the boom apparatus 210, including a hydraulic valve control, a lighting system, and a sensor network.
[0163] In certain embodiments, the second portion 406 can include a cab bearing plate 478 which can facilitate the rotational interface between the cabin 208 and the boom apparatus 210. The cab bearing plate 478 can be disposed to accommodate the mechanical load generated during simultaneous rotation of both the cabin 208 and boom apparatus 210 while maintaining structural integrity in operation.
[0164] With reference to
[0165] The third portion 408 can also provide electrical power via a conduit system 486 that can be disposed at the second end 440 of the core 402. The conduit system 486 can include one or more conduit ports 488 that can be configured to run a control wire, a DC wire, and/or other electrical connections from the first end 438 via the electrical hub 416 to the second end 440 for front chassis 202 electrical power distribution. In certain embodiments, the conduit port 488 can be constructed with a strain relief mechanism and can be positioned to provide secure routing of electrical cables while maintaining protection from environmental factors and mechanical stress. The conduit system 486 can accommodate various types of electrical connections including the control wire for system operation, the DC power wire for electrical operation of the first portion 404 and the second portion 406, and communication lines for data transmission between the first portion 404, the second portion 406, and the third portion 408 of the dual power swivel system 400.The conduit system 486 can rotate with the electrical hub 416 and the front chassis 202, allowing for continuous electrical connectivity while accommodating the rotational requirements of the dual power swivel system 400.
[0166] In certain embodiments, third portion 408 can include a bracket 490 coupled to an exterior surface of the second jug 480 for coupling the third portion 408 stationary within the front chassis 202. Although the bracket 490 can couple the third portion 408 stationary within the front chassis 202, it should be appreciated that the entirety of the dual power swivel system 400 is coupled to the machine 200 via the bracket 490 however, as described herein, the first portion 404 and the second portion 406 can rotate independently of the third portion 408 to move the cabin 208 and the boom apparatus 210, respectively. The bracket 490 can be positioned to engage with a corresponding mounting point within the front chassis 202 and can be configured to resist rotational forces while maintaining the stationary position of the third portion 408 relative to the front chassis 202. In certain embodiments, the bracket 490 can include multiple attachment points and can be configured to distribute mechanical loads effectively across the mounting interface of the front chassis 202, promoting stable operation during machine 200 movement and operation.
[0167] Returning now to the core 402 as shown in
[0168] As described herein, the core 402 can include multiple port 462 configurations for different functional requirements throughout the dual power swivel system 400. In a particular embodiment shown in
[0169] The core 402, the first portion 404, the second portion 406, and the third portion 408 of the dual power swivel system 400 can enable independent rotation while maintaining continuous electrical and hydraulic power distribution throughout the machine 200. The rotational axis (A) of the core can permit electrical conduit to run from the first end 438 to the second end 440 while housing various ports 462 that distribute hydraulic fluid to the various machine components. The first portion 404 can be disposed about and coupled to the core 402 and can be configured to rotate with the cabin 208 of the machine 200. The second portion 406 can be rotatably disposed about the core 402 and configured to rotate with the boom apparatus 210. The third portion 408 can be disposed about the core 402 and remain stationary within and coupled to the front chassis 202, providing both hydraulic power and electrical power to the front chassis 202. The core 402 configuration can enable the first portion 404 and the second portion 406 to rotate independently of one another and independently of the third portion 408, allowing the cabin 208 and the boom apparatus 210 to rotate independently of one another and the front chassis 202 while maintaining uninterrupted power transmission through the arrangement of slip rings, manifolds, and hydraulic distribution ports within the dual power swivel system 400.
EXAMPLES
[0170] The following example demonstrates an embodiment of the present disclosure in use. The example is provided for illustrative purposes only and should not be construed as limiting the scope of the present disclosure. It will be appreciated by those skilled in the art that various modifications, alternatives, and variations of the example can be made without departing from the scope of the present disclosure as defined by the appended claims.
[0171] At the start of the workday, an operator parks the machine 200 to load a tool set into the dump body 234 and climbs the step 218 to enter the cabin 208. The dump body 234 provides versatile storage capacity for various materials including tools, cut stone, logs, firewood, pallets, crushed stone aggregate, and topsoil during operation. A coworker joins the operator in the cabin 208, demonstrating how the machine 200 facilitates efficient crew transport to remote work locations.
[0172] Upon reaching the worksite, the operator opens the hinged tailgate 240 to retrieve the tools from the dump body 234. Before beginning sandstone collection, the operator deploys the outrigger 222 for enhanced stability during operations. From the ergonomic position in the cabin 208, the operator skillfully coordinates the boom arm assembly 256, utilizing the precise control of the boom 264, boom stick 268, bucket 274, and thumb 278 to securely grip the sandstone. The thumb 278 moves in opposition to the bucket 274, creating a secure grip on the material throughout the entire operation.
[0173] Throughout the day, the operator maximizes efficiency by utilizing the rotation capability of the machine 200. The boom apparatus 210 rotates continuously and without limitation through the boom rotation actuator 260, enabling 360-degree material transfer from any collection point around the machine 200. Simultaneously, the cabin 208 rotates independently through the cabin rotation actuator 250, allowing the operator to maintain optimal visibility between the dump body 234, the boom arm assembly 256, and the worksite as the sandstone is collected for transport. The power swivel system 206 facilitates the coordinated movement through independent sections that enable separate rotation capabilities for the cabin 208 and boom apparatus 210.
[0174] Using the comprehensive operator controls housed in the cabin 208, the operator manages all machine functions including movement, cabin 208 rotation, rear chassis 204 positioning, lift mechanism 226 operation, dump body 234 manipulation, tailgate 240 position and boom apparatus 210 control. The rear chassis actuator 230 allows for up to 20 degrees of flexion on each side of vertical from the front chassis 202 relative to the rear chassis 204, helping maintain stability while navigating challenging terrain conditions during travel to and from the worksite. It should be appreciated that the flexion function can lock when the lift mechanism 226 is deployed, to avoid machine 100 twist during lift operation.
[0175] As the dump body 234 continues to fill with sandstone, the operator and the coworker can make several trips to and from the worksite to retrieve and deliver more sandstone. When transporting the collected materials, the machine 200 maintains stability and traction through the rear chassis actuator 230, ensuring secure operation even on uneven terrain.
