Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a ladder-type cable bridge which is easy to adjust. Background Art

[0002] Cable trays come in trough, tray, ladder, and grid configurations, and are composed of brackets, supports, and mounting accessories. Cable trays can be installed independently within buildings or attached to various structures and pipe gallery supports. They should feature simple structure, attractive design, flexible configuration, and easy maintenance. All parts must be galvanized. Ladder-type cable trays offer high strength, light weight, low cost, attractive design, easy installation, and good air permeability. They are suitable for laying cables with larger diameters, and are particularly suitable for high- and low-voltage cables carrying heavy loads.

[0003] In the prior art, a ladder-type cable tray is usually composed of two side panels with grooves and a plurality of laying rods fixed at intervals between the two side panels with grooves. The two ends of the laying rods are welded and fixed to the grooves of the side panels so that the cables can be stably laid flat on the laying rods. However, since the laying rods are welded in the grooves, the width of the cable tray cannot be adjusted, and the laying requirements of cables of different sizes cannot be met, thereby reducing the applicability of the cable tray. Utility Model Content

[0007] As an optimal technical solution of the present invention, a connecting groove for the connecting column to be plugged in is provided on the side of the fixed column away from the first baffle, and symmetrical guide blocks are provided on the two inner side walls of the connecting groove. Guide grooves adapted to the guide blocks are symmetrically provided on both sides of the connecting column.

[0008] As a preferred technical solution of the present invention, the connecting column is provided with a plurality of evenly distributed first connecting holes for connecting bolts, and the fixing column is provided with a second connecting hole connected to the first connecting holes.

[0009] As a preferred technical solution of the present invention, a plurality of weight-reducing holes are provided through the first baffle and the second baffle.

[0010] As an optimal technical solution of the present invention, a sliding rod is slidably connected to the mounting plates on both sides of the threaded hole, one end of the sliding rod is fixedly connected to the driving plate, and the other end of the sliding rod extends to the outside of the mounting plate and is provided with a stop plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When the width of the bridge body needs to be adjusted, the user first loosens and removes the connecting bolts inserted into the first connecting hole and the second connecting hole, then drives the driving plate to move the first baffle by rotating the threaded rod through the driving handle, thereby adjusting the width of the bridge body. After the width of the bridge body is adjusted, the second connecting hole on the fixing column is connected to one of the first connecting holes on the connecting column, and the connecting bolt is inserted into the connected first connecting hole and the second connecting hole to fix them, thereby fixing the displacement of the first baffle.
