Description

Overhead line lead wire safety fixing device Technical Field The invention relates to the technical field of live working tools, in particular to a safety fixing device for overhead line leads. Background Live disconnection and wire connection are conventional tasks in live working practice of a power distribution network, but the detached wire is often suspended in the air, and the method is hidden in a non-negligible safety risk. Firstly, the problem of interphase short circuit is extremely easy to cause, and particularly under the action of wind power, the lead wire in a suspended state is easy to contact with the lead wire of the adjacent phase, so that the short circuit accident is directly caused. Secondly, the lead of the accessed line may also induce electricity to the phase that is not connected, which may not only interfere with the subsequent work of the operator, but may also constitute a safety hazard to touching the wire. Moreover, for operators who use an insulating glove operation method to perform live wire breaking and wire bonding, the operators need to pay attention to avoiding wires suspended in the air at all times, which increases the difficulty and complexity of the operation. In the existing method, an operator locks a drainage wire close to one end of a line by using an insulating lock rod, a ground electrician uses an insulating rope to transfer an insulating wire binding shear and three teeth to the rod, and the laid drainage wire is fixed on a cross arm or an electric pole to prevent the drainage wire from swinging or affecting operation. The operation of winding the drainage wire at high altitude is unchanged, and has great potential safety hazard. Too long and too short drainage wire is not suitable for winding the drainage wire on the electric pole. Disclosure of Invention The invention provides a safety fixing device for an overhead line lead, which can realize free movement and fixation of clamping points, adjust the distance between wires so as to install a wire clamp, realize quick and convenient completion of live wire breaking and lead connection work, effectively solve the problems of difficult operation and the like, eliminate potential safety hazards of induction electric and interphase short circuit, and reduce labor intensity. The specific technical scheme is as follows: The overhead line lead safety fixing device comprises a first insulating rod, a second insulating rod and a wire clamping assembly, wherein the first insulating rod and the second insulating rod are arranged in a mutually perpendicular mode, one end of the first insulating rod is connected with the middle of the second insulating rod, the wire clamping assembly comprises a first wire clamping assembly, a second wire clamping assembly and a third wire clamping assembly, the first wire clamping assembly is arranged at one end of the second insulating rod, the third wire clamping assembly is arranged at the other end of the second insulating rod, and the second wire clamping assembly is arranged at the other end of the first insulating rod.
