An electric pull-wire device with oscillating and intermittent loopback actuation

Abstract

The invention discloses an electric wire drawing device having swing and intermittent return execution. The electric wire drawing device comprises a body rack component, a wire inlet hole, a swing wire component, an inlet wire tape transmission component, an upper roller component, handle components, a wire outlet hole, universal wheel components, an outlet wire gear transmission component, an outlet wire tape transmission component, a motor component, a worm and gear transmission component and a lower roller component. The motor in the motor component realizes the situation that one motor drives two transfer lines; the cam groove of the cam in the swing wire component is designed into the irregular concave-convex contour of smooth transition so as to realize irregular swinging of the inlet wire; the axis height position of the lower roller component is fixed, and the axis height position of the upper roller component is upward and downward adjusted in a U-shaped groove so as to realize mutual clearance adjustment; and a control module controls forward and backward rotation of the motor in the motor component so as to realize intermittent return operation of wire drawing. The electric wire drawing device is simple in structure, flexible to move, low in manufacturing cost and smooth in wire drawing process through manual operation simulation so that the wire drawing efficiency of wire laying can be enhanced.

Description

Technical field [0001] The invention relates to the technical field of a wire pulling device for building construction wiring, in particular to an electric wire pulling device with swing and intermittent return execution. Background technique [0002] In building construction, according to the requirements of the drawings, various wire pipes are laid open or hidden on the ground, wall or roof of the building, and then various wires or cables are laid in the pipeline. The way of laying the wires is to tie the wires to the steel wire (or oil wire rope), put the end of the steel wire (or oil wire rope) through the initial threading hole, pass through the target threading hole, and then pull it manually Pull the steel wire (or oil wire rope) outward until all the steel wire (or oil wire rope) is pulled out, untie the binding end of the wire and the steel wire (or oil wire rope), and complete the wire pulling of the wiring. In the wire drawing work of wiring, the work of pulling...
