Description

Technical Field

[0001] The invention belongs to the technical field of aerial cable stringing, and in particular relates to a self-moving wire clamp. Background Art

[0002] With the development of economy and society, there are more and more power grid construction projects, stricter safety requirements and tighter construction schedules. The construction of overhead transmission lines can be divided into five processes: material transportation, tower assembly, line laying and tightening, and accessory installation. Among them, the line laying and tightening stage has the greatest safety risk, the most high-altitude workers, and the low level of mechanized construction.

[0003] Based on the existing technical conditions and equipment status, there are two general solutions for laying and tightening wires. The first is the traditional capstan or tensioning machine, hand winch and ordinary wire clamp, and the second is the centralized control tensioning visualization equipment, electric wire clamp and ordinary wire clamp. Due to the strict requirements of the safety production concept and the actual demands of the construction of power transmission and transformation projects, higher requirements are put forward for the mechanized construction of the laying and tightening process. At present, the power transmission projects under construction by State Grid Corporation basically recommend the use of the second solution. However, the second solution still has shortcomings and does not meet the requirements of "mechanized replacement of personnel" and "mechanized reduction of personnel". It still requires high-altitude workers to install wire clamps on the conductors, which poses a great safety risk of falling from heights. In addition, when using the existing wire clamps, the operator needs to use both hands to force the wire clamps to open and clamp the cables, which is not easy to operate at high altitudes and may increase the risk of falling.

[0004] Patent CN218102313U discloses an adjustable wire clamp for power maintenance, including a main body, a block and a fixed block are cast on the top of the main body by an integrated casting process, an extrusion block, a safety block, a linkage block, a push rod, and a guide mechanism are arranged on the top of the main body, and a power-assisting mechanism for assisting the linkage block in unlocking operation is arranged inside the fixed block. This prior art sets a power-assisting mechanism, and when it is necessary to release the clamping operation of the wire, the gear is driven to move downward by pressing down the adjustment rod, and the gear moves downward to mesh with multiple sets of teeth, and then the push rod and the adjustment rod are squeezed to rotate the adjustment rod, so that the push rod can be pushed to move, and the push rod moves, and then the clamping operation of the wire can be released, that is, the power-assisting operation of the push rod is completed, so that it is convenient for the staff to use the wire clamp.

[0005] The above patent solves the problem of the inconvenience of using the wire gripper through an assist mechanism, making it convenient for secondary use. However, the operator still needs to wear a safety rope and lie on the suspended cable that needs to be tightened, and send the wire gripper from the starting working point of the cable to the target position of the cable and clamp the cable. The operator then climbs back to the starting working point along the cable, drags the wire gripper with the sprocket, and then repeats the above steps until the suspended cable is straightened and fixed. During this process, the operator is at a high altitude and only relies on the suspended cable as support to work. The labor intensity of the operator increases, which ultimately leads to reduced working efficiency and a safety hazard of falling risk. Summary of the invention

The remote control mechanism is used to remotely control the operation of the roller mechanism 400 and the tightening mechanism 500. The power supply mechanism 600 is arranged at the bottom of the shell 100 to power the wire clamp. The wire clamp designed by the present invention can replace the manually installed wire clamp, and the wire clamp can be controlled by the remote control mechanism. The operation of the roller mechanism 400 can be controlled, so that the self-moving wire clamp can reach the designated working place along the cable 200. The operation of the tightening mechanism 500 is controlled by the remote control mechanism. Before arriving at the designated place, the tightening mechanism 500 keeps the wire clamping mechanism 300 in an open state. When arriving at the designated working place, the tightening mechanism 500 is driven to operate so that the wire clamping mechanism 300 is closed and clamps the cable 200 to complete the wire clamping. Subsequently, the subsequent work is completed by cooperating with the electric wire tensioner. The wire clamping mechanism 300 can also use the LGJ185-240 model wire clamp commonly used on the market to be applied to this application.

Grooves are respectively provided at the upper end of the plate 320 and the lower end of the wire clamping block 313, and the two grooves cooperate to form a wire clamping groove for clamping the cable 200. The relative positions of the wire clamping plate 320 and the wire clamping block 313 are changed by the coordinated movement of the first connecting rod 330 and the second connecting rod 340 to open or close the wire clamping groove; the cable 200 can be clamped in the wire clamping groove by the positioning plate 310, the wire clamping plate 320, the first connecting rod 330 and the second connecting rod 340 and other components.
