Description

Technical Field

[0001] This invention relates to the field of power engineering construction technology, and in particular to a cable connection protection device and its usage method for power engineering. Background Technology

[0002] Currently, existing cable connection protection devices for power engineering have many shortcomings in practical applications. Regarding cable fixing, traditional devices often have unreasonable clamping structures, employing single-directional clamping or lacking synchronous linkage mechanisms. This results in the lower and upper clamping heads failing to coordinate their movements, making it difficult to form a stable and secure clamp on the cable. During wiring, the cable is prone to shaking due to external forces or operator contact, affecting the accuracy of wiring operations, increasing the probability of wiring errors, and potentially causing poor contact at the connection point, leading to overheating, short circuits, and other safety hazards, seriously threatening the normal operation of the power system and the personal safety of operators. In terms of device versatility, the diverse diameters and specifications of cables used in power engineering necessitate the connection of different cable types in different scenarios. Existing protection devices often have fixed clamping heads rigidly connected to the device body, making flexible disassembly and replacement impossible based on cable diameter. This means that a single protection device typically only fits cables within a specific diameter range. When facing different cable specifications, the entire protection device needs to be replaced, increasing equipment investment costs and reducing operational efficiency, making it difficult to meet the complex and ever-changing wiring requirements of power engineering projects. Summary of the Invention The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a cable wiring protection device for power engineering. Through a vertical cylinder driving gear transmission, the lower clamping head and the upper clamping head can move synchronously, stably and firmly clamping the cable, preventing cable swaying during wiring and avoiding safety hazards such as overheating and short circuits, thus providing safety protection for the cable wiring process. At the same time, the lower and upper clamping heads can be disassembled and replaced with fixing bolts to adapt to cables of different diameters, effectively improving the device's versatility. The height of the wiring platform can be adjusted by a servo motor in conjunction with a vertical lead screw, and combined with the limiting function of the guide rod, it can be adjusted to a comfortable working height according to the operator's needs, improving wiring convenience.

The movement of the upper clamping head 13, which in turn drives the U-shaped outer rack frame 14 to move downward, causes the upper clamping groove 12 of the upper clamping head 13 to engage with the lower clamping groove 11 to clamp the cable. The guide plate 1 5 and the guide plate 2 7 guide the movement of the U-shaped inner rack frame 4 and the U-shaped outer rack frame 14, respectively.
