Pay-off retainer and use method thereof

Abstract

The invention relates to a pay-off retainer. The pay-off retainer comprises an operation box, a pay-off part and a tension control part, wherein the pay-off part comprises a pay-off spool and a braking mechanism, the top of the pay-off spool is provided with a wire supporting cylinder, the bottom of the pay-off spool is connected with a rotating shaft, the braking mechanism is arranged on the rotating shaft, the braking mechanism comprises a brake drum, a brake block, a return spring and a brake rib, the tension control part is arranged on an operation door, the tension control part comprisesa control spring, a pay-off pulley block, a connecting rod mechanism and a limiting handle, one end of the control spring is fixedly connected with the operation door, the other end of the control spring is connected with the brake rib of the braking mechanism, the pay-off pulley block comprises a first force bearing pulley, a second force bearing pulley and a sensing pulley, the first force bearing pulley and the second force bearing pulley are fixed at the inner end and outer end of the inner side face of the operation door respectively, and the sensing pulley is slidably arranged in a vertical sliding groove in the inner side face of the operation door through a sliding block; the connecting rod mechanism comprises a sensing rod, a linkage rod and a control rod, and a control handle isrotatably connected to the operation door through a mounting end.

Description

Technical field [0001] The present invention relates to the field of electric power technology, in particular to a pay-off holder that is convenient to carry, safe to use, and fully mechanically operated. Background technique [0002] The construction chief of the overhead line needs to use some tools and equipment to take certain methods to complete the assembly and maintenance of each component to ensure the safe operation of the line. Workers generally simply pull out the wires from the reel when wiring and taking up wires in the field. When wiring, the staff are all hand-drawn wires, and the staff cannot accurately control the pulling force when they are pulling the wires. The pulling force is often too strong and the speed is too fast. When the pulling force is too large, the wire exiting speed is too fast, and Under the action of inertia, the wires will continue to go out. At this time, if the staff are unable to wire the pulled wires immediately, a large number of pulled ...

AI Technical Summary

Problems solved by technology

When wiring, the staff all pull the wires with bare hands. When pulling the wires with bare hands, the staff cannot accurately control the pulling force. Often the pulling force is too strong and the speed is too fast. Under the action of inertia, the wires will continue to go out. At this time, if the staff cannot immediately route the pulled out wires, a large number of pulled out wires will gather locally and serious line knotting will occur; when the wires are taken up, the staff still It is necessary to take up the wire with bare hands, and the work of coiling and winding will still bring a lot of pressure, and it is difficult for the staff to accurately control the tension of the coil with bare hands. If the coil is too loose or too tight, it will seriously affect the next use

The above situations will greatly affect the operating efficiency of the staff, especially when a single person is doing field work, it is even more difficult to complete the wiring work quickly and effectively
