A laying device that can prevent cable damage

Abstract

The invention relates to a laying device capable of preventing cable damage; its technical solution includes a trolley, a cable reel is arranged on the left side of the trolley, a first pulley is installed on the cable reel, and the cable reel The left side of the barrel is provided with a second pulley driven by a motor, a loose first belt is installed between the first pulley and the second pulley, and a pressing wheel that can move up and down is installed under the first belt , the pressing wheel moves upwards and squeezes the first belt to make the motor drive the cable reel to rotate. There is an L-shaped bar on the right side of the trolley, and a winding wheel is provided on the rear side of the L-shaped bar. The bottom of the trolley rotates. Connect a friction wheel that is in contact with the ground. There is a first roller that can move up and down in the middle of the trolley, and a second roller that can move up and down is arranged on the right side of the first roller. The first roller is down The movable pinch wheel squeezes the first belt.

Description

technical field [0001] The invention relates to the field of subway construction equipment, in particular to a laying device capable of preventing cable damage. Background technique [0002] During the construction of the subway, a large number of cables need to be laid inside it. In order to facilitate management, multi-layer cable supports will be erected on the side walls of the subway. Cables for different purposes are placed on different cable supports. The height of the cable supports is different. Therefore, auxiliary construction equipment is required for the installation of cables. At present, the laying of cables at higher positions is often done manually by workers using ladders. This method of erection is inefficient and there is a risk of people falling. The erection of the cable is pulled out from the cable drum by the erection vehicle and lifted. The above operation has the risk of straining the cable. In order to prevent the cable from being strained, two peo...
