Abstract

The invention discloses a wire repair backup protection device and a using method thereof. The protection device comprises rotating frames, bearing seats, pressure bearings and hook bases; each rotating frame comprises a rotating frame seat and a rotating frame cover; one end of the rotating frame cover is movably connected with the rotating frame seat; the other end of the rotating frame cover is connected with the rotating frame seat through a bolt; the rotating frame is provided with a hollow cavity; the bearing seat, the pressure bearing and the hook seat are sequentially arranged inside the cavity from outside to inside; the periphery of the hook seat is provided with an opening through which a wire can pass; one side of the hook seat, which is opposite to the opening, is fixed with a hook; two ends of at least one rotating frame seat are provided with a first screw rod and a second screw rod respectively; and two rotating frames are connected with each other through two ropes. According to the using method of the wire repair backup protection device of the invention, after the protection device is installed, in a pre-twisted wire winding process, the two rotating frames are pushed such that synchronous rotation before and after operation can be realized. With the wire repairing backup protection device and the using method thereof of the invention adopted, the problem of the hindering of pre-twisted wire winding in a wire repair process can be solved.

Description

【Technical field】 [0001] The invention relates to the technical field of wire repair for overhead transmission lines, in particular to a backup protection device for wire repair and a method for using the same. 【Background technique】 [0002] In the daily operation and maintenance of overhead transmission lines, if the wires are broken or damaged, most of the repairs to the damaged wires are repaired with pre-twisted wires. At this time, the damaged cross-section of the wire does not exceed 25% of the conductive cross-section. At present, most of the backup protection tools for repairing wires use double hooks or three pulleys. The use of the above two tools may lead to: (1) the operation is not flexible enough, which hinders the normal winding of the pre-twisted wire, resulting in deformation of the pre-twisted wire during winding; ( 2) During the operation, the operator loses the backup protection, which increases the operation risk. This greatly reduces the construction ...
