Abstract

The invention discloses a macromolecule PVC profile ladder type bridge. The macromolecule PVC profile ladder type bridge comprises two groups of ladder sides and ladder beams arranged between two groups of ladder sides in parallel; a first fixed steel, a second fixed steel and a third fixed steel are arranged at medial surfaces of two groups of ladder sides, the first sliding rails are arranged atadjacent surfaces between the first fixed steel and the second fixed steel, a first sliding bar is arranged between two groups of first sliding rails; the ladder beam is arranged on the first slidingbar on two groups of ladder sides; the second sliding rails are arranged on adjacent surfaces of the second fixed steel and the third fixed steel; a second sliding bar is arranged between two groupsof second sliding rails; the ladder beam is arranged on the second sliding bar on two groups of ladder sides, ball strips are arranged between the first sliding bar and two groups of first sliding rails and between the second sliding bar and two groups of second sliding rails. The entire length of the bridge can be increased or shortened at will in the use process, and the reserved length of the cable is convenient to adjust.

Description

technical field [0001] The invention relates to the field of cable laying equipment, in particular to a polymer plastic-steel ladder bridge frame. Background technique [0002] Ladder bridge is a new type improved by the company based on relevant domestic and foreign materials and similar products. It has the advantages of light weight, low cost, unique shape, convenient installation, good heat dissipation, and good air permeability. It is suitable for the laying of cables with large diameters in general, especially for the laying of high and low voltage power cables. Ladder bridges are equipped with protective covers, which can be specified when ordering if they are required. All accessories are common to tray and trough bridges. [0003] During the use of the ladder bridge, due to the short-distance movement of the power equipment, there is often a phenomenon that a long section of the cable connecting the equipment is reserved, and when a long cable is reserved, a bridge...
