Novel cable bridge

Abstract

The invention relates to a novel cable bridge which comprises straight grooves hinged to each other. The bottoms of the two straight grooves are connected and fixed through a connecting bottom plate, and the included angle between the two straight grooves is adjustable. A sliding block is arranged on the connecting bottom plate in a sliding manner, a boss is arranged on the straight groove, and a connecting rod is arranged between the sliding block and the boss. A vertically-through center guide groove is formed in the connecting bottom plate, a lead screw is rotatably arranged at the lower end of the connecting bottom plate, and the sliding block is slidably arranged in the center guide groove; the upper end of the sliding block is rotatably connected with the connecting rod, the lower end of the sliding block is in threaded connection with the lead screw, and an outer vertical plate is arranged between the side vertical surfaces of the two straight grooves. A vertically-through first sliding groove is formed in the straight groove, a vertically-through second sliding groove is formed in the connecting bottom plate, and a shaft pin is inserted in the crossed and overlapped position of the first sliding groove and the second sliding groove. The invention further discloses a cable corner adjusting method which can adjust the corner of the cable bridge and can meet the installation requirements under various use working conditions.

technical field [0001] The invention relates to the technical field of circuit equipment, in particular to a novel cable tray. Background technique [0002] The cable bridge is used to install and fix cables, and it is divided into trough type, tray type, ladder frame type, grid type and other structures. The bridge frame in the building can be erected independently or attached to various buildings and pipe gallery supports. Cable bridge It is a straight-line structure. When a corner is required, two bridges need to be welded and connected, which is very inconvenient to install.

Problems solved by technology

[0002] Cable trays are used to install and fix cables, and are divided into trough type, tray type, ladder frame type, grid type and other structures. The bridge frame in the building can be erected independently, or It can be attached to various buildings and pipe gallery supports. The cable bridge is a linear structure. When corners are required, two bridges need to be welded and connected, which is very inconvenient to install.

[0003] When the corner angle needs to be adjusted, the cable can only be taken out, the bridge frame is cut off and welded again, which is very inconvenient and wastes manpower and time during construction

[0004] In the prior art, there are also cable trays that can adjust the angle, but most of them have a limited range of angle adjustment and the adjustment method is not simple enough, which affects the use and installation on site
