Description

Technical Field

[0001] The utility model relates to the technical field of power line construction devices, and particularly relates to a winding and unwinding device for power line construction. Background Art

[0002] A power line refers to a line used to transmit electric energy between a power plant, a substation and power users. It is an important part of the power supply system and is responsible for the tasks of transmitting and distributing electric energy. A power line connects a transformer substation and each electric energy user or electrical equipment, and is a conductor loop that transmits and distributes electric energy from the power supply end (transformer substation) to the load end (electric energy user or electrical equipment). Generally, power lines are interconnected through cables.

[0003] Existing cables are generally wound on cable reels. When in use, workers place the cable reel on the winding and unwinding device of the power line and manually tow the cable to move it. However, when the existing winding and unwinding device winds and unwinds the cable, it is not convenient to clamp and fix the cable. After the cable manually towed by the worker is moved to a suitable position, the cable reel still continues to rotate and release the cable, resulting in waste during cable laying. Moreover, manually towing the cable by workers will cause some cables to be in the air, thus posing a certain safety hazard.

[0004] Therefore, it is very necessary for us to propose a winding and unwinding device for power line construction to solve the above problems. Content of the Utility Model

[0029] The working principle of this utility model:

[0030] Refer to the attached drawings of the specification Figures 1-4 , by pushing the sliding column 203, the sliding column 203 drives the limit column 204 to squeeze the telescopic spring 205 to contract and move, so that the sliding column 203 moves to drive the limit column 204 to move, so that the limit column 204 moves to drive the fixing column 206 to move, and the fixing column 206 moves out of the limit bolt 202, releasing the connection and fixation between the limit bolt 202 and the main body 1 of the retracting and deploying device. Then rotate the limit bolt 202 so that the limit bolt 202 rotates out of the clamping ring 201, releasing the connection and fixation between the clamping ring 201 and the main body 1 of the retracting and deploying device, and the position fixation of the cable reel 101 on the main body 1 of the retracting and deploying device can be released, completing the disassembly and replacement operation of the cable reel 101;

[0031] Refer to the attached drawings of the specification Figures 1-4, the worker pulls the cable on the cable reel 101 through the traction ring 301 and connects it to the equipment for fixation, then the worker moves the main body 1 of the winding and unwinding device by pushing the support push rod 102, so that the main body 1 of the winding and unwinding device drives the cable reel 101 to perform the cable unwinding operation, and the cable is laid on the road surface through the traction ring 301, thus reducing the certain safety hazards existing when the cable floats in the air.

Therefore, after the unwound cable moves to a suitable position, it will not continue to unwind under the rotation of the cable reel 101 itself, causing waste of the cable. At the same time, the movement of the support plate 305 drives the tapered block 307 to move and squeeze the connecting plate 308, so that the connecting plate 308 squeezes the support spring 310 to contract and move, and the connecting plate 308 drives the locking block 309 to move from the inside of the support push rod 102 to the inside of the main body 1 of the winding and unwinding device, completing the limit locking of the main body 1 of the winding and unwinding device, and then the cable wound and unwound by the cable reel 101 can be clamped and fixed, and the main body 1 of the winding and unwinding device can be limited and fixed.
