Description

Technical Field

[0001] The invention relates to the technical field of cable bridges, and in particular to an improved cable bridge which is convenient for maintenance. Background Art

[0002] Cable trays are divided into trough, tray, ladder, grid and other structures, and are composed of brackets, brackets and installation accessories. The cable trays in buildings can be erected independently or laid on various buildings (structures) and pipe gallery brackets. They should have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the open-air cable trays outside the building.

[0003] Cable trays are mainly used for laying cables. Due to different usage environments, different types of cable trays are selected. Although the existing cable trays that seal and lay cables can protect the cables well, the cables are wrapped and sealed, which is very inconvenient during maintenance. After long-term use, the cables are prone to surface cracking due to their own aging or external environmental influences. If they are not repaired in time, the internal copper wires will be exposed, causing short circuits or even damage. Therefore, the cables need to be regularly inspected and maintained, but the closed laying method makes it very inconvenient to lay the cables. In special circumstances, the cables will have problems due to their centralized laying. Summary of the invention

[0046] The working principle of the present invention is:

[0047] When laying the cable, place the cable in the receiving groove 702 between the locking column 711 and the bearing plate 701, and drive the driving threaded rod 706 to drive the clamping plate 707 to move downward through the pull ring 705, so that the adjusting spring 709 is squeezed and deformed, thereby clamping and fixing the cable in the receiving groove 702, and twisting the fastener 8 on the driving threaded rod 706 so that the connecting thread end 801 on the fastener 8 is connected to the connecting threaded column 712, thereby limiting the displacement of the driving threaded rod 706, improving the stability of the cable clamping and fixing, and then the protective shell 4 is tightened. The guide groove 405 is aligned with the guide column 5 on the bridge cover 1 for plugging, so that the snap-in plate 404 on the protective shell 4 is plugged into the snap-in groove 101 on the bridge cover 1, and at the same time, the guide plate 301 on the bridge bottom plate 3 is plugged into the guide groove 407 on the protective shell 4, so that the protective shell 4 is installed on both sides of the bridge cover 1. At this time, the first mounting hole 501 of the guide column 5 is connected with the second mounting hole on the protective shell 4, and the mounting bolt 6 is inserted into the connected first mounting hole 501 and the second mounting hole for fixing, that is, the protective shell 4 is fastened and installed on both sides of the bridge cover 1. The present invention can separate and place cables of different specifications and sizes laid in the bridge body through the setting of the fixing mechanism 7, which can better protect each cable, further improve the convenience and efficiency of the staff during maintenance, and avoid the concentrated accumulation of cables of different specifications and sizes to generate heat, thereby improving the heat dissipation performance of the bridge body.

[0048] During maintenance, the mounting bolts 6 inserted into the first mounting hole 501 and the second mounting hole are removed, and then the protective shell 4 is removed from both sides of the bridge cover 1, so that there is sufficient maintenance space on both sides of the bridge body, and at the same time, the cables classified and placed on the wire fixing mechanism 7 in the bridge body are exposed, thereby improving the convenience and efficiency of maintenance for the staff.
