Impact-resistant combined cable bridge

Abstract

The invention discloses an impact-resistant combined cable bridge, and the cable bridge comprises a bridge body, a first buffer assembly, a second buffer assembly and a supporting assembly. A bottom plate of the frame body is provided with an upward rectangular groove, and the top end of a side plate of the frame body is connected with an upper cover in a buckled mode. The first buffer assembly isarranged on the lower surface of the frame body in an array mode, and the first buffer assembly comprises a guide rod, a sliding ring, a connecting rod and a first spring, wherein the upper end of the connecting rod is rotationally connected with the interior of a U-shaped connector arranged on the lower surface of the rectangular groove through a pin shaft, and the lower end of the connecting rod is rotationally connected with the interior of the top end of the sliding ring through a pin shaft; The adjacent sliding rings are slidably connected with the outer arc faces of the guide rod, and the ends of the guide rods are fixedly connected with the inner walls of the left side plate and the right side plate of the supporting plate correspondingly. According to the invention, the cable bridge is good in heat dissipation performance, convenient to install and operate, capable of improving the protection performance, capable of conducting buffering protection in the horizontal direction and the vertical direction at the same time, good in impact resistance, long in service life, high in practicability, and wide in application range.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to an impact-resistant combined cable bridge. Background technique [0002] Cable bridges are divided into trough type, tray type, ladder frame type and grid type, etc., which are composed of brackets, brackets and installation accessories. The bridges in buildings can be erected independently or attached to various buildings and pipe gallery brackets. In terms of structure, it should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. If the bridge frame installed in the open air outside the building is near the sea or belongs to the corrosion area, the material must have Anti-corrosion and moisture-resistant, the combined bridge is the second-generation product of the cable bridge. It is suitable for various projects, various units and various cables. It has the characteris...

Problems solved by technology

[0002] Cable bridges are divided into trough type, tray type, ladder frame type and grid type, etc., which are composed of brackets, brackets and installation accessories. The bridges in buildings can be erected independently or attached to various buildings and pipe gallery brackets. In terms of structure, it should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. If the bridge frame installed in the open air outside the building is near the sea or belongs to the corrosion area, the material must have Anti-corrosion and moisture-resistant, the combined bridge is the second-generation product of the cable bridge. It is suitable for various projects, various units and various cables. It has the characteristics of simple structure, flexible configuration, convenient installation and novel form. The combined cable tray has a single function and cannot separate the cables. The heat dissipation effect is not good, and it is easy to cause a large amount of heat to accumulate between the cables, which affects the service life of the cable. Moreover, the impact resistance is poor, and it is easy to cause internal cable pull. The bridge is easily deformed and affects the service life. Therefore, we propose an impact-resistant combined cable bridge to solve the above defects
