Push-pull electrified live wire lapping clamp

Abstract

The invention discloses a push-pull electrified live wire lapping clamp, which comprises a wire clamp main body comprising a side plate with a wiring part and a hook head fixed at the upper end of theside plate, a transmission box fixed to the lower end of the side plate, having the inner part with a cavity, and provided with first penetrating openings right opposite to each other in the upper end and the lower end respectively, a sliding assembly comprising a screw rod penetrating through the first penetrating openings and a clamping block which is arranged at the upper end of the screw rodand is opposite to the hook head, and a non-return assembly comprising a warping rod hinged in the transmission box, a first extrusion piece pressed on the warping rod, a pressing plate hinged to theinner end of the warping rod, and a traction piece with one end connected to the lower end of the pressing plate and the other end bypassing the outer end of the warping rod. According to the invention, the operation difficulty of fastening the live wire clamp by the insulating rod can be greatly reduced, so that the operation time and risk can be reduced; meanwhile, the tight contact between thewire clamp and the main wire can be ensured, and the wire clamp is prevented from being separated.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a push-pull live wire clamp. Background technique [0002] With the rapid development of the power grid and the continuous improvement of the requirements for power supply reliability in various industries, live work has become an important means of construction and maintenance to effectively reduce user outage time, improve customer service quality, and improve the economic benefits of the power grid. One of the important live-work projects is liveline work (connecting and fixing the drain wire to be externally connected to the main wire of the power grid through a clamp to realize the power-taking process of the drain wire). The work of live-fired distribution network can be carried out by using ground potential insulating rod method, intermediate potential insulating rod, and insulating gloves. Currently, there are many live-fired methods and clamps, among w...

Problems solved by technology

[0003] The line clamp needs to cooperate with the insulating rod for on-site installation operation, but the currently used live loading and unloading line clamp has the following disadvantages: when installing the line clamp, it is suspended and fixed on the main line by rotating the bolt at the end of the insulating rod, but due to the operation object It is a 10KV live fire operation, and the operation is difficult. If only the insulating rod is used to rotate the bolt, it is difficult to exert the rotating torque. Therefore, when the bolt is rotated, it cannot be well stressed, which makes it difficult for the clamp to be in close contact with the main wire. problems, and there is a risk of weak contacts or even disengagement
