Integrated adjustable bridge structure for high-voltage cable construction

Abstract

The invention provides an integrated adjustable bridge structure for high-voltage cable construction. The integrated adjustable bridge structure comprises side plates, a fixed clamping shaft and a movable end clamping groove; the bottoms of two groups of the side plates are connected through multiple groups of bottom surface connecting rods; a group of lock pins are slidably connected to the innersides of the bottoms of each group of side plates; and multiple groups of bridge support arms are plugged together at the bottoms of the two groups of the side plates. According to the integrated adjustable bridge structure for the high-voltage cable construction provided by the invention, the two groups of the side plates are connected together and a bottom surface is formed by adopting a shears-fork mechanism; the distance between the two groups of side plates can be arbitrarily adjusted during use, and the bridge width can be conveniently adjusted; at the same time, a roller is fixed on the clamping groove by a clamping tooth when the clamping tooth is released by hands, so that the shears-fork mechanism cannot be changed, so that the bridge width can be fixed, and different numbers ofcables can be applied; and when cables in the bridge are increased, the width of the bridge can be adjusted without re-adding or replacing the bridge, thereby reducing the installation operations, increasing the construction speed and reducing the cost.

Description

Technical field [0001] The invention belongs to the technical field of electric power engineering, and more specifically, relates to an integrated adjustable bridge structure used for high-voltage cable construction. Background technique [0002] In the process of high-voltage cable construction, bridges are often used to place and protect cables. Integrated bridges are widely used due to their simple structure and fast installation speed. The existing integrated bridges are generally fixed U-shaped structures. [0003] For example, application number: CN201110419890.6. The present invention discloses an integral ladder type cable tray, which includes two ladder sides and a cross arm. The ladder sides and the cross arm are made of a single piece of sheet metal stamping, and the cross arm is provided with A groove-shaped reinforcing rib, both ends of the groove-shaped reinforcing rib are bifurcated in a Y shape, a cross section of the middle part of the groove-shaped reinforcing rib...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an integrated adjustable bridge structure for high-voltage cable construction to solve the problem that the existing integrated bridge cannot change the width of the bridge due to its fixed structure, and different widths need to be selected according to actual use requirements during use. Type of bridge, but also to reserve a certain amount of reserve, in the later maintenance and use process, when the spare amount is insufficient, it is necessary to increase the bridge or replace the bridge of different width models, the construction is complicated, the construction period is long, and the construction cost is high question
