Abstract

The invention belongs to the technical field of cable maintenance, in particular to a welding device for cable breakage maintenance. For general cable sheath maintenance, a crack part is cut off, a new insulating sheath is welded manually and the efficiency is lower; in order to solve the above problems, the invention provides the following scheme: the device comprises a first rubber ring and a second rubber ring which are fixed on the outer wall of a cable; a grip is adhered to one side of the second rubber ring, and fixed rings are arranged on the outer walls of the first rubber ring and thesecond rubber ring; and first fixed blocks are welded at the top ends and the bottom ends of the two fixed rings. According to the invention, the T-shaped slideway at the bottom end of the second fixing block drives the blade to descend; when a cable is cut into the sheath of the cable, the fixing ring is rotated to enable the blades to cut the outer wall of the cable open, the blades are heatedto enable the cut part of the cable to be melted, the rubber strip is placed between the two blades to enable the two sides of the triangular rubber strip to be heated, and finally the heated and melted rubber strip is pressed on the cut part of the cable to be welded together.

Description

technical field [0001] The invention relates to the technical field of cable maintenance, in particular to a welding device for cable fracture maintenance. Background technique [0002] Cable is an important carrier of electric energy transmission, but after the cable is used for a long time, it is prone to breakage, pitting and other phenomena, which will affect the normal use of the cable and easily cause safety accidents. Generally, the maintenance of the cable will cut off the cracked part, and then Weld a new insulating sheath, but this method generally relies on manual operation, and the efficiency is relatively slow. [0003] After retrieval, the Chinese patent application number is CN201720818079.8, which discloses a cable detection and maintenance device, including a detection and maintenance box. The detection and maintenance box is fixedly connected by an upper box and a lower box through a hinge. The inner wall of the upper box is fixed with a cable detector; th...
