Electric wire device for construction site, and electric wire stringing and protecting method

Abstract

The invention belongs to the field of electric wire devices, and particularly relates to an electric wire device for the construction site. The electric wire device for the construction site comprisesa base, supports, a winding roller, a belt pulley A, a synchronous belt, a belt pulley B, a damping ring, an electric drive module and the like. The two supports are symmetrically arranged on the base with a moving device; and when a worker is carelessly stumbled by a use-state transition cable released from the winding roller, a suspended transition cable can pull the winding roller to rotate for two to three circles under the action of an external force, a volute spiral spring is compressed so as to store energy, and the transition cable is continuously released for a certain length by therotating winding roller so as to form buffer on the external force stressed by the transition cable, so that the transition cable is prevented from being pulled and damaged under the action of the stumbling external force, the service life of the transition cable is prolonged, the worker stumbled by the transition cable is prevented from being unbuffered stumbled by the cable so as to fall off, and the activity safety of working personnel is further ensured.

Description

technical field [0001] The invention belongs to the field of wire devices, and in particular relates to a wire device used on construction sites and a method for threading and protecting wires. Background technique [0002] In order to facilitate the use of power on the construction site, it is usually necessary to use a long transition cable to extend the power socket to the vicinity of the equipment that needs to be connected to the power supply on the construction site. Generally, the length of the transition cables used as power sockets on the construction site is relatively long, and they are generally stacked randomly or placed on the ground; The cables together will have dead knots during the unwinding process, which will affect the efficiency of the equipment to connect to the power supply; when the transition cables are used up, their recovery is troublesome and inefficient, and the recovered cables are not standardized due to their later stacking. As a result, a d...

Generally, the length of the transition cables used as power sockets on the construction site is relatively long, and they are generally stacked randomly or placed on the ground; The cables together will have dead knots during the unwinding process, which will affect the efficiency of the equipment to connect to the power supply; when the transition cables are used up, their recovery is troublesome and inefficient, and the recovered cables are not standardized due to their later stacking. As a result, there will be dead knots in the process of reuse, which will affect the efficiency of cable use.
