Auxiliary device for laying cable in horizontal tray and laying method

Abstract

The invention discloses an auxiliary device for laying a cable in a horizontal tray and a laying method. The auxiliary device comprises a roller and limiting plates which are sheathed at the two ends of the roller. Radial through holes are respectively arranged at the two ends of the roller. Bolts penetrate through the radial through holes and are locked on the roller through nuts. The two limiting plates are arranged on the internal sides of the bolts. When the cable is laid, the roller is horizontally supported on the horizontal cable at first and the two limiting plates are arranged on theexternal sides of the two side walls of the horizontal tray; then the cable is laid from one end of the tray to the other end of the tray along a tray cable trough and is supported through the rollerof the auxiliary device when the cable passes through the auxiliary device; when the cable passes over the roller, the cable can be pulled to enable the roller to rotate and the cable can be laid in place during the rotation of the roller; and after the cable is laid in place, the auxiliary device is taken down and the cable is enabled to fully fall into the tray to complete the final laying of the cable. The auxiliary device for laying the cable in the horizontal tray has the advantages that the effort is saved during cable laying and the cable is not apt to be damaged.

Description

technical field [0001] The invention relates to cable laying technology, in particular to an auxiliary device for laying cables in a horizontal bridge frame. The invention also relates to a method for laying cables in the horizontal bridge frame. Background technique [0002] In large-scale building construction, the laying of cables is a project with a lot of work. On professional construction sites, cables are usually laid in bridges, which are standardized, tidy, and easy to maintain. The cross-section of the bridge frame is "U"-shaped, and the cables are laid in the "U"-shaped groove. Before the cables are laid, the bridge frame is fixed on the wall or the roof through the bracket. Bridges are divided into horizontal bridges and vertical bridges. When laying cables on horizontal bridges, first pass one end of the cable through the bridge along the wire groove, and then pull the passing end manually to finally lay the cable in place. The cable laying process has at lea...

AI Technical Summary

Problems solved by technology

The cable laying process has at least the following deficiencies: 1. Since the cable is directly pulled through the bridge, the length of the bridge generally has a length of 20-60 meters. Sliding friction, the contact area between the cable and the bottom of the bridge frame is large, and the rubber skin covered by the cable has a large friction coefficient, so the friction force is very large, and a large force is required to pull it. When pulling, it often takes several people to complete the laying task. , so the efficiency is low and the labor cost is high; 2. Due to the high friction between the cable and the bridge, it is easy to wear the rubber skin of the cable during the pulling process, thus damaging the cable
