Anti-loose cable winding device for hydroelectric installation

Abstract

This utility model belongs to the technical field of cable winding equipment, specifically relating to a cable winding device for preventing loosening during hydropower installation. It includes a base plate, with side plates fixedly connected to the surface of the base plate. A winding roller is rotatably connected inside the side plates. A disassembly / assembly mechanism is provided on the side plates. A slide block is slidably connected to the upper end of the base plate. A motor is fixedly installed at the front end of the base plate, with the motor's shaft passing through the base plate and rotatably connected to it. This utility model uses a motor to drive a screw to rotate and a slider to perform a threaded motion, allowing the slide block to reciprocate, resulting in more even cable winding. Simultaneously, by rotating a bidirectional screw and a pressure plate to perform a threaded motion, the pressure plate can compress a sliding plate via a spring, causing the sliding plate to move and the mounting base to move. This, in turn, causes the pressure roller to compress the cable, keeping it taut during winding and preventing loosening or bending.

Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically a cable winding device for preventing loosening in hydropower installation. Background Technology

[0002] Utility model patent CN220376022U discloses a cable rewinder for hydropower installation, including a support frame, a rewind roller, a drive unit, and a cable management assembly. One end of the drive unit's transmission shaft passes through the support frame and is fixedly inserted into the rewind roller; the other end is fixedly connected to a drive handwheel. A toothed plate on one side of the rewind roller is connected to a transmission gear of the cable management assembly. The transmission gear is fixedly connected to one end of a reciprocating screw. A cable hook is installed at the lower part of a sliding seat threaded onto the reciprocating screw. This device uses a manually driven rewind roller to rewind cables placed on the ground. During rewinding, one end of the cable is passed through the cable hook on the cable management assembly and fixed to a placement hook. Then, the drive unit drives the rewind roller to rotate, facilitating stable cable rewinding. The overall structure is simple, easy to operate, and the cable rewinding speed is fast and efficient, reducing the workload of workers. However, this device has some shortcomings: the rewind roller is not easily disassembled and replaced, and the cable is prone to loosening and bending during the rewinding process. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a cable winding device for hydropower installation that prevents loosening, which solves the problem that the winding roller is inconvenient to disassemble and replace, and also prevents the cable from becoming loose and bent during the winding process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cable winding device for preventing loosening during hydroelectric installation, comprising a base plate, a side plate fixedly connected to the surface of the base plate, a winding roller rotatably connected inside the side plate, a disassembly and assembly mechanism provided on the side plate, a slide block slidably connected to the upper end of the base plate, a motor fixedly mounted at the front end of the base plate, the motor shaft passing through the base plate and rotatably connected to the base plate, a screw fixedly connected to the end of the motor shaft, the screw block rotatably connected to the base plate, a straightening mechanism provided on the slide block, a slider fixedly connected to the lower end of the slide block, the slider block slidably connected to the base plate, and the slider block and the screw block connected by a thread.

[0005] Preferably, a mounting plate is fixedly connected to the right end of the slide, and a guide cylinder is fixedly connected inside the mounting plate. The guide cylinder guides the cable.

[0006] Preferably, the disassembly and assembly mechanism includes a bracket. A bracket is fixedly mounted on the front end of the side plate, and a motor is fixedly mounted on the front end of the bracket. The output end of the motor passes through the bracket and is rotatably connected to it. A slide cylinder is fixedly connected to the end of the motor's output end. A square rod is slidably connected inside the slide cylinder, and the square rod is slidably connected to the take-up roller. A spring is installed inside the slide cylinder, with one end fixedly connected to the slide cylinder and the other end fixedly connected to the square rod. The square rod is moved by a sliding pin, allowing for engagement and disengagement control between the square rod and the take-up roller under the action of the spring, thereby enabling the device to disassemble and replace the take-up roller.

[0007] Preferably, a sliding pin is fixedly connected to the surface of the square rod, and the sliding pin is slidably connected to the slide cylinder. The sliding pin guides the movement of the square rod.

[0008] Preferably, the straightening mechanism includes a mounting base, a mounting base slidably connected inside the slide block, a pressure roller rotatably connected inside the mounting base, a sliding plate fixedly connected to the rear end of the mounting base, the sliding plate and the slide block being slidably connected, a bidirectional screw being movably connected inside the sliding plate, a limiting plate fixedly connected to the rear end of the slide block, the limiting plate and the bidirectional screw being rotatably connected, a pressure plate threadedly connected to the outer side of the bidirectional screw, the pressure plate and the slide block being slidably connected, and a compression spring provided on the outer side of the bidirectional screw. The screw is driven by a motor to rotate and the slide block to perform threaded motion, thereby allowing the slide block to reciprocate, resulting in more uniform cable winding. Simultaneously, by rotating the bidirectional screw and the pressure plate to perform threaded motion, the pressure plate can compress the sliding plate through the compression spring, causing the sliding plate to move the mounting base, which in turn causes the pressure roller to compress the cable, keeping the cable taut during winding and preventing loosening and bending.

[0009] Preferably, a guide plate is fixedly connected to the front end of the mounting base, and the guide plate is slidably connected to the slide. The guide plate guides the movement of the mounting base.

[0010] Preferably, one end of the compression spring is fixedly connected to the pressure plate, and the other end of the compression spring is fixedly connected to the slide plate. By setting the compression spring, the slide plate is elastically compressed.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a sliding pin to drive the square rod to move, so that the square rod can be engaged and disengaged from the take-up roller under the action of a spring, thereby enabling the device to disassemble and replace the take-up roller.

[0013] 2. This utility model uses a motor to drive the screw to rotate and the slider to make a threaded motion, which allows the slide to move back and forth, making the cable winding more even. At the same time, by rotating the bidirectional screw and the pressure plate to make a threaded motion, the pressure plate can squeeze the slide plate through the pressure spring, which in turn allows the slide plate to drive the mounting base to move, which in turn allows the pressure roller to squeeze the cable, keeping the cable in a taut state during the winding process and preventing the cable from becoming loose or bent.
