Description

Technical Field

[0001] This utility model belongs to the field of cable tightening technology, and in particular relates to a cable tightening device for power installation. Background Technology

[0002] In industries such as power, communications, and transportation, the installation of cables (including conductors, electrical cables, optical cables, etc.) is a core part of infrastructure construction.

[0003] Traditional cable laying is mainly manual, and cable tightening is often done manually by a large number of workers. This method of tightening not only consumes a lot of labor costs, but is also inefficient. Moreover, manual pulling of cables poses significant safety hazards, which may cause accidents such as collisions or entanglement to workers. Therefore, we propose a cable tightening device for power installation. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tensioning device for power installation. By setting up a tensioning section, specifically, a pulley 1 drives a pulley 2 to rotate via a belt, and the pulley 2 drives a reciprocating screw to rotate. The reciprocating screw drives a moving frame to reciprocate along a slide bar 2, which can make the cable wound more evenly on the tensioning roller. The tensioning roller tightens the cable. When tightening the cable, the cable is tightly attached to the rotating shaft. Due to the cooperation of the spring and damper, the tension of the cable when tightening it too quickly can be reduced, preventing it from being torn. The operation is simple and greatly improves the safety of construction. It solves the problem that the existing traditional cable laying is mainly manual, and the cable tightening work is often done manually by a large number of workers. This tensioning method not only consumes a lot of labor costs, but its efficiency is also relatively low. Moreover, manual pulling of cables poses considerable safety hazards, which may cause workers to have accidents such as collisions or entanglement.

[0016] Furthermore, the clamping assembly includes a motor mounted on the front of the base plate, and a bidirectional threaded rod is fixedly connected to the output end of the motor on the back. Two arc-shaped rings are threadedly connected to the outer surface of the bidirectional threaded rod.

[0017] The arc-shaped ring has two sliding rods inside, and the front and back of the sliding rods are fixedly connected to the inner wall of the base plate. The two threads on the bidirectional threaded rod are in opposite directions.

[0018] Furthermore, the tightening assembly includes two support frames installed on the right side of the base plate. A second motor is fixedly connected to the back of the support frame, and a tightening roller is fixedly connected to the front output end of the second motor via a coupling.

[0019] A second sliding rod is provided above the tightening roller. The front and back of the second sliding rod are fixedly connected to a fixing frame. The left side of the fixing frame is fixedly connected to the right side of the base plate.

[0020] Furthermore, the cable management assembly includes a movable frame, the interior of which is slidably connected to the outer surface of the slide rod two, and a reciprocating screw is rotatably connected to one side of the two fixed frames opposite to each other. A pulley two is fixedly connected to the front of the reciprocating screw, and the outer surface of the reciprocating screw is threadedly connected to the interior of the movable frame.

[0025] 1. This utility model, by setting up a cable tensioning part, specifically, involves a pulley 1 driving a pulley 2 to rotate via a belt, which in turn drives a reciprocating screw to rotate. The reciprocating screw then drives a moving frame to reciprocate along a slide bar 2. This allows the cable to be wound more evenly on the tensioning roller, which then tightens the cable. During cable tightening, the cable is pressed tightly against the rotating shaft. The combination of springs and dampers reduces the tension on the cable when it is pulled up too quickly, preventing it from breaking. The operation is simple and greatly improves construction safety.

[0026] 2. This utility model incorporates an anti-drop component. Specifically, the starting motor drives the gear to rotate, which in turn drives the rotating ring to rotate. The rotating ring, through its internal arc groove, causes the clamping block to slide along the inside of the disc, temporarily fixing the cable in place. Finally, the excess cable can be cut off for installation, facilitating the installation process.

[0027] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The reciprocating motion of rod 316 allows the cable to be wound more evenly on the tightening roller 313. The tightening roller 313 tightens the cable, keeping it close to the rotating shaft 326. The cooperation of spring 324 and damper 325 reduces the tension on the cable when it is pulled too fast, preventing it from breaking. After the cable tightening is complete, the excess cable needs to be cut off. Before this, start motor 3 413 to drive gear 414 to rotate. Gear 414 drives rotating ring 415 to rotate.
