This robot system includes a robot on which a driver bit for rotating a screw is mountable, and a robot controller that controls the robot. The robot controller gives a command to the robot to insert a teaching jig into a screw hole which is to be threaded with the screw in a state where the teaching jig is mounted instead of the driver bit, and determines a direction in which the driver bit is inserted by adjusting a direction in which the teaching jig is inserted so as not to cause a load due to interference between the teaching jig and the screw hole.

A machine for track maintenance is manually displaceable on a track. The machine has a work module with a handle, a working tool powered by a drive and a machine frame configured to be guided on a rail of the track. The work module is detachably connected to an energy module and the energy module has an electrical energy store and output contacts. The output contacts are detachably connected to input contacts of the work module. The work module has as the drive an electric motor supplied with electrical energy from the energy store. This solution results in a high degree of overall efficiency because the energy available in the energy store serves for the largest part for covering performance peaks.

The present invention relates to an apparatus for fastening a functional element to a section of a workpiece and/or for reshaping a section of the workpiece, said apparatus comprising a support device for supporting the workpiece, wherein the workpiece section has a first surface facing the support device and a second surface facing away from the support device. The support device comprises a first support element having a first workpiece support surface that is associated with the first surface, and a second support element having a second workpiece support surface that faces away from the first workpiece support surface and that is associated with a supporting surface. The first and the second support element are movable relative to one another by means of a spreading device such that the first and the second workpiece support surface can be moved away from one another in an axial direction, in particular wherein the axial direction extends perpendicular to the first and/or second workpiece support surface.

The present disclosure provides a multifunctional climbing operation platform and an operation method thereof. The multifunctional climbing operation platform includes a main machine, clamping devices, a bolt retightening device, and an auxiliary sleeve replacement box, wherein the clamping devices each include: a fixed seat; and a pair of claw bars swingably arranged on the fixed seat and each including a rear bar body and a front bar body hinged together, wherein when the pair of claw bars are opened, an inner angle between the rear bar body and the front bar body is greater than 180°, the main machine and the clamping devices can climb along an object to be climbed, the bolt retightening device can replace different sleeves from the auxiliary sleeve replacement box, and can screw a bolt on the object. The present disclosure has the advantages of a large avoidance range and diverse functions.

One or more system and associated methods for installing a line spacer upon adjacent lines that are suspended are provided. A system includes a portion for holding and releasing the line spacer onto the lines. The system includes a portion for actuating securing portions of the line spacer to secure the line spacer upon the lines. The system includes a flying drone portion for levitation of the portion for holding and the portion for articulating to the lines.

A clamping device for a screw connection, provided with a threaded bolt and a threaded nut, has a support tube surrounding the threaded nut, a cylinder housing arranged in an extension of the support tube, a piston movable in the cylinder housing by hydraulic pressure, an exchange bushing axially entrainable by the piston and provided with an internal thread for screwing the exchange bushing to the threaded bolt, and a follower element arranged inside the support tube and frictionally or with form fit connectable to the threaded nut. A drive element is rotatably mounted outside the support tube and provided with a tool surface for applying a hand tool. A gear arrangement is located between the drive element and the follower element. The gear arrangement has a clutch operating as a function of torque to prevent reliably excessive forces when the threaded nut is re-tightened and/or screwed on.

A tube coupling apparatus includes first and second clamping jaws that are mounted on a tool body. The clamping jaws are movable relative to each other between an open configuration in which they are receive a compressible tube connector, and a closed configuration in which they apply a compression force to compress the compressible tube coupling about one or more tube members. An actuator is arranged to move at least one of the clamping jaws to the closed configuration and a controller is operative to control the actuator. A sensor is provided that is arranged to determine a system parameter indicative of the compression force applied to the coupling by the clamping jaws and to progressively increase the compression force of the clamping jaws during a fitting operation. The controller monitors the system parameter data from the sensor and automatically controls the actuator to prevent the compression force exceeding a predetermined threshold based on the sensor data.
