Cable threading traction device for building electrical engineering

Abstract

The invention relates to the technical field of cable traction devices, and discloses a cable threading traction device for building electrical engineering. Through arrangement of a heating motor, a heating wire and the like, a heat shrink tube is shrunk, and a cable leather sheath is wrapped and thickened so that subsequent traction is facilitated, and damage to the cable leather sheath by adopting a traditional net sleeve mode is avoided; through the arrangement of a winching machine, a pull disc and the like, the pull disc drives an upper shell and a lower shell to move towards one side, through the arrangement of semicircular holes, the upper shell and the lower shell drive the cable leather sheath to move towards one side of the winching machine, then the purpose of damage-free traction is achieved, and through the arrangement of a control rod and the like, stable traction can be achieved, and the cable leather sheath is prevented from being separated during traction due to the too thin cable leather sheath; and through the arrangement of a fixing cone, a suction cup and the like, distinguished reinforcement is achieved according to different geologies, and a situation that a pay-off rack slides accidentally in the traction process and accidents are generated is avoided.

Description

technical field [0001] The invention relates to the technical field of cable pulling devices, in particular to a cable threading and pulling device for building electrical engineering. Background technique [0002] Cable is a kind of electric energy or signal transmission device, which is usually composed of several wires or groups of wires. Cable traction machine is a kind of machinery used for traction when laying cables. The traction of cables and overhead lines can also be used in other occasions that require traction. It can be used alone, or it can be used in conjunction with pay-off trailers, pay-off machines, pay-off racks, etc. [0003] In the prior art, when traction machines such as winch mills are used for cable traction, it is necessary to connect a net sleeve to one end of the traction steel wire, and then connect the net sleeve to one end of the cable. This method is easy to cause damage to the outer sheath of the cable. This then affects the normal use of th...
