A combined cable tray

Abstract

The invention provides a combined-type cable bridge stand. Through cooperation usage of a matched stand column, a bridge arm and a connection component, a purpose of rapid installation is reached. Installation is simple, assignment is beautiful, and installation quality and installation efficiency are increased. A bolt is used to connect an adjusting support and 360 degree rotation of the adjusting support is realized so that a contact area of a supporting arm and the bridge stand can be increased, hoisting of the supporting arm after rotation is realized and bending-resistance and torsion-resistance mechanical performance of the supporting arm is optimized. A plurality of plug grooves on the stand column are used to provide a plurality of different heights for the supporting arm, and the height of the supporting arm can be adjusted up and down according to a height of cable laying. At an occasion where the bridge stand needs to be laid at different heights before and after a cable, when the bridge stand needs to be arranged in an inclined mode, inclination arrangement can be realized through adjusting a lifting device. According to an actual condition of a site landform, flexible assembling can be performed, orientations and lengths are changed from multiple angles, an obstacle is avoided, multi-angle adjusting can be completed and a steering function in a cable line is realized.

Description

technical field [0001] The invention relates to the field of oil purifiers, in particular to a combined cable bridge. Background technique [0002] The cable tray product is a new type of cable laying device developed by industrially developed countries in the early 1960s. With the high development of electrification and automation, especially the change of power distribution mode, the direct burial of trenches and the laying of cables on brackets can no longer meet the requirements of use, and they are replaced by cable trays, thus speeding up the construction progress, ensuring quality, and realizing product quality. Standardization, serialization, generalization. Cable tray is a device for fixing cables, widely used in petroleum, chemical industry, electric power, light industry, telecommunications and other industries, mainly used for the laying of overhead power cables, control cables, lighting lines, and telecommunication cables. Commonly used bridges are generally m...

Problems solved by technology

When cable laying requires the use of bridges, there are the following disadvantages. First, when faced with multi-fork intersections and complex and changeable project erection environments, the bridge installation cannot change the shape of the facility, and it is difficult to mount the cables and difficult to install. After installation, the style is not beautiful, and the placement of the cables is very messy; second, the existing cable bridges usually punch out ventilation holes on the bottom and sides, and use the external natural wind to heat the cables inside the bridge. However, from the actual effect, The cables are not sufficiently cooled, and it is prone to fire after a long time
