Description

Technical field [0001] The invention relates to the technical field of power grounding wires, in particular to an automatic winding device for grounding wires. Background technique [0002] As the base station in the power grid, the substation is the hub of high and low voltage conversion and an important part of the entire power grid. Therefore, it is necessary to frequently shut down power equipment such as lines and main transformers in conjunction with production and maintenance plans. In order to prevent sudden calls from the equipment and threaten personal safety, various equipment such as lines and main transformers need to be grounded. At this time, grounding is required. line. The grounding wire for power transformation is usually made of multiple strands of high-quality soft copper wire, and is covered with a soft, high-temperature-resistant transparent insulating sheath, which can prevent the abrasion of the grounding copper wire during use. [0003] Due to the long le...

Problems solved by technology

There is an organic case on the bottom plate, and a motor is arranged in the case. The end of the output shaft of the motor far away from the motor is connected with a winding pile for winding the grounding wire. The motor can drive the winding pile to rotate through the output shaft. The wire clamp at one end of the wire clamp can clamp the end of the grounding copper wire. The wire clamp includes a fixed block fixed on the side of the winding pile close to the motor and a fixer matched with the fixed block. On the fixed block A clamping hole matching the grounding wire is provided, and a fixing hole communicating with the clamping hole is provided on the side of the fixing block away from the winding pile, and a plurality of card slots are provided on the side wall of the fixing hole along the length direction of the fixing hole , the fixer includes an operating head, one side of the operating head is provided with a fixed rod that matches the fixing hole, one side of the fixed rod is provided with a block that matches the slot, and the side of the fixed rod away from the block is provided with a Pressure groove, there is a pressure block slidingly arranged in the pressure groove, and the pressure block is connected with the side wall of the pressure groove through a compression spring. The side of the pressure block away from the operating head is provided with a guide slope. Insert one end of the fixed block into the clamping hole on the fixed block, and then move the operating head to insert the fixed rod into the fixed hole. The side of the fixed rod with the block is on the same side as the slot. The sum of the widths is less than the width of the fixing hole, so that the fixing rod can be smoothly inserted into the fixing hole. The force makes the pressure block overcome the elastic force of the compression spring and move to the inside of the pressure groove. As the fixed rod continues to move, the pressure block will be forced into the pressure groove so that the pressure block does not affect the movement of the fixed rod in the fixed hole. When the bottom end of the rod touches the ground wire, insert the block into the slot at the corresponding position, and then press the block tightly against the side wall of the fixing hole under the action of the compression spring to realize the fixer and fixation The fixed connection between the blocks, and can fix one end of the grounding wire to prevent the occurrence of off-line stool when winding. The setting of multiple card slots enables the clamp to clamp grounding wires of different models and sizes, and then start the motor , the motor rotates evenly, thereby driving the wiring pile to rotate, and the grounding wire is evenly wound on the pile. Press the inside of the groove, then the block is out of the groove, and then the retainer is moved out of the fixing hole so that the clamp does not fix the end of the ground wire, and the wound ground wire is removed along the winding pile and put into storage In the bag, when you use it next time, you only need to take it out and place it, which will not cause knotting and wear. There is a stop plate on the end of the winding pile away from the motor. The setting of the stop plate makes the grounding wire be wound It is not easy to fall off when the grounding wire is used, and the stability is higher. The whole device saves time and manpower to a great extent. In the case of frequent use of the grounding wire, it effectively prolongs the service life of the grounding wire.
