Description

Technical Field

[0001] The invention relates to the technical field of cable tensioning, and in particular to a cable tensioning device for electric power construction. Background Art

[0002] During the cable installation and wiring process, ensuring the tightness of the cable is crucial to the overall performance and safety of the system. A loose cable may cause poor signal transmission, physical damage, or even affect the normal operation of the equipment, and in severe cases may cause failure or shutdown. Therefore, traditionally, construction workers tighten the cable manually to ensure that the cable is in an appropriate tension state.

[0003] However, this manual tightening method has multiple defects. First, the accuracy and consistency of manual tightening are difficult to guarantee, which may lead to uneven tension of the cable at different positions, affecting the stability and reliability of the entire system. If the cable at one end is not tightened enough and the other end is over-tightened, it may cause local stress concentration, and eventually cause cable damage or aging. Secondly, long-term manual tightening operations will cause fatigue of construction workers, thereby reducing work efficiency and safety, and increasing the risk of work errors. In some special environments, such as high-altitude operations or confined spaces, manual tightening operations face many safety risks. Construction workers must maintain their body balance when tightening, which may cause accidental falls or equipment loss of control, increasing the possibility of accidents. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, the purpose of the present invention is to propose a cable tensioning device for power construction, which can solve the problem that the accuracy and consistency of manual tensioning are difficult to ensure, which may cause uneven tension of the cable at different positions, thereby affecting the stability and reliability of the entire system. In addition, long-term manual tensioning operations may cause fatigue of construction workers, thereby reducing work efficiency and safety. In some special environments, such as high-altitude operations or narrow spaces, manual tensioning operations are even more exposed to safety risks, increasing the possibility of accidents.

[0006] To achieve the above-mentioned purpose, the present invention proposes a cable tensioning device for power construction, comprising a guide side plate, a support head, a rotating rod, a reinforcement sleeve, a mounting plate, a driving device, a wire-laying mechanism and a limiting mechanism, wherein two guide side plates are provided, the two supporting heads are respectively fixedly connected to the inner walls of the two guide side plates, the two ends of the rotating rod are rotatably connected to the inner walls of the supporting heads, the reinforcement sleeve is fixedly sleeved on the outer wall of the rotating rod, the mounting plate is fixedly connected to the outer wall of one of the guide side plates, the driving device is installed on the outer wall of the mounting plate, and the output end of the driving device is fixedly connected to one end of the rotating rod, the wire-laying mechanism is provided with two groups, and is symmetrically installed on the outer wall of the reinforcement sleeve in a V-shaped structure, the limiting mechanism is provided with two groups, and is rotatably connected to the inner wall of the guide side plate, and the limiting mechanism is connected to the wire-laying mechanism.

[0007] In the cable tensioning device for power construction of the present invention, the cable ends are passed through the top and bottom of the two wiring mechanisms in sequence, and the limiting mechanism then fixes the cable position to prevent displacement. In order to achieve efficient tightening of the cable, a support head is installed on the inner wall of the guide side plate, and the two ends of the rotating rod are rotatably connected to the support head. The rotating rod and the reinforcement sleeve are driven to rotate by starting the driving device, so as to gradually tighten the cable. The limiting mechanism is connected to the wiring mechanism to prevent the cable from loosening or sliding during the tightening process, thereby ensuring the stability of the cable. Through the cooperation of these mechanisms, efficient and stable fixation and tightening of the cable are achieved, thereby avoiding the difficulty in ensuring the accuracy and consistency of manual tightening, which may cause uneven tension of the cable at different positions, thereby affecting the stability and reliability of the entire system. In addition, long-term manual tightening operations may cause fatigue of construction personnel, thereby reducing work efficiency and safety. In some special environments, such as high-altitude operations or narrow spaces, manual tightening operations are even more faced with safety risks, increasing the possibility of accidents.

In order to achieve efficient tightening of the cable, a support head 2 is installed on the inner wall of the guide side plate 1, and the two ends of the rotating rod 3 are rotatably connected to the support head 2. The rotating rod 3 and the reinforcement sleeve 4 are driven to rotate by starting the driving device 6, so as to gradually tighten the cable.
