Disclosed are a synchronous movement apparatus of tracks in a wellbore inspection system and a control method thereof. The synchronous movement apparatus includes an upper moving track, a lower moving track, an upper wire rope moving device, a lower wire rope moving device, and a control device; the upper moving track and the lower moving track are correspondingly embedded into an inner wall of a wellbore, and the upper moving track is located above the lower moving track; the upper wire rope moving device is fitted in the upper moving track, and the lower wire rope moving device is fitted in the lower moving track; the upper moving track and the lower moving track have the same structure and each include a track body. A rolling face is arranged on the track body, and grooves are evenly distributed on the rolling face along the extending direction of the track body.

A wireline assembly enclosure. The wireline assembly enclosure has a first half and a second half which define an interior compartment. The first and second halves are attached via a hinge and move from an open configuration to a closed configuration. The enclosure also has a plurality of apertures. In various embodiments a stuffing box, lubrication tubing, and other materials pass through the apertures into the interior compartment. A sealing material is disposed partially about a perimeter of the first and second halves such that a seal is formed when the two halves are together in the closed configuration. The sealing material is also disposed about a perimeter of the plurality of apertures. An adjustable bar clamp inside the interior compartment of the enclosure clamps hardware in place. The enclosure is secured around a stuffing box and sheave in order to contain overspray from a wireline.

A lifting cabinet includes a transmission assembly and a power unit for raising and lowering a shelf. The transmission assembly comprises a first transmission unit, comprising a screw rod which is connected with a driving device and a sliding piece which is connected with the lifting shelf, and the sliding piece is coupled to the screw rod. The screw rod rotates under the action of the driving device and drives the sliding piece to move back and forth along the axis of the screw rod; and then the sliding piece drives the lifting shelf to move up and down. For the lifting cabinet and the power unit thereof, the transmission assembly converts a rotary motion outputted from the driving device into a linear motion through the cooperation between the screw rod and the sliding piece, and a greater axial force is thereby outputted. Thus, a relatively small motor with a lower output torque can be used in the lifting cabinet to drive a lifting shelf of the same weight when compared to the conventional lifting cabinet, and the problem of large motor in conventional lifting cabinet taking up too much space is thereby solved.

A portable pulling device and method therefore, the portable pulling device including a chassis frame, a power source, anchoring elements, a spool, a rope or cable attached thereon, and a centrifugal clutch with a chain or belt drive system allowing the ability to pull out the rope when the power source is at idle. The device further contains frame propulsion components such as wheels, skis, or tracks to facilitate movement of the pulling device into and through a confined area such as a forest or a barren area.

A device for moving an object is disclosed. The device has a drive cylinder with drive grooves and a set of idler pulleys. The idler pulleys are on a shaft that is parallel to the drive cylinder. Each of the idler pulleys rotate at an angle around the drive shaft that aligns the grooves of the idler pulleys to neighboring drive grooves. This allows the line to pass onto the drive groove, around an idler pulley, and onto a next adjacent drive groove. The line therefore winds back and forth between the drive grooves, the idler pulleys, and back to the next drive groove. One end of the line is placed under tension and the other is attached to an object or to a fixed member. The drive cylinder is driven and the line is moved through the device, or the device is moved along the line, respectively.

A robot system for maintenance of a building façade with an irregular façade surface is provided. The robot system includes a platform cooperating with a least four pairs of cables for positioning the platform at a distance from a building façade. At least one robot arm is situated on the platform, and includes an adaptor positioned at a distal end thereof for holding and manipulating a building façade maintenance tool. An actuator drives the cables to move the platform to any arbitrary position along the building façade. A controller cooperates with the actuator to instruct the actuator to drive the cables and to control movement of the robot arm, such that driving the actuator and movement of the robot arm is coordinated by the controller; any position deviations in the platform are compensated for by positioning or movement of the robot arm.
