Description

Technical Field

[0001] The invention specifically relates to a combined power cable bridge. Background Art

[0002] Cable tray is a structure used to support and protect cables, widely used in electrical engineering and construction. Its main function is to guide cables from one place to another while protecting them from mechanical damage, chemical corrosion and other environmental influences.

[0003] The existing power cable bridge is relatively simple and has a fixed shape. When the number of cables to be wired is too large, a smaller bridge is difficult to meet the needs. When the number of cables to be wired is small, a larger bridge will leave a lot of space and cause waste. It is not convenient for users to combine bridges of different shapes according to actual needs to meet the installation and wiring of different types and quantities of cables. In addition, the length of the bridge cannot be fine-tuned during wiring to improve the convenience of wiring in complex environments. For this reason, we propose a combined power cable bridge.

[0043] Preferably, the telescopic assembly 4 includes a first telescopic support plate 401, a connecting plate 402 and a second telescopic support plate 403. One end of the first bridge frame 1 is connected to the second telescopic support plate 403 through a first damper. The first telescopic support plate 401 is installed on the other end of the first bridge frame 1 through a second damper, and the side wall of the first telescopic support plate 401 has a connecting plate 402 that matches the second telescopic support plate 403, which is convenient for connecting multiple first bridge frames 1 in the horizontal direction.

[0046] The working principle and use process of the present invention are as follows: when in use, the partition plate 602 is moved along the height direction of the guide block 601, and then the locking bolt 605 is screwed to one side of the slider 603 to compress the elastic sheet 606 and the guide block 601 to achieve close contact, so that the inner side of the first bridge 1 can be divided into two wiring spaces, and then the cables can be arranged in the inner sides of the two wiring spaces according to the type and number of the cables to be arranged, so as to facilitate the later inspection and maintenance. Furthermore, when the number of cables is large, the first bridge 1 and the second bridge 2 can be arranged alternately in the vertical direction, so that the first bridge 1 and the second bridge 2 can be arranged alternately. The connection is achieved by cooperating with the lifting block 302 and the hanging column 303. After wiring, the opening on the second bridge frame 2 is sealed by the sealing cover 7 on the lower surface of the first bridge frame 1. At the same time, according to the cable length, the first telescopic support plate 401 and the second telescopic support plate 403 can be pulled to the side away from the first bridge frame 1 respectively, so that the bridge frame length can be fine-tuned. When multiple first bridge frames 1 are arranged in the horizontal direction, two first bridge frames 1 can be combined by the first telescopic support plate 401, the second telescopic support plate 403, the connecting plate 402 and the connecting bolts, so as to facilitate the construction of a wiring channel with a longer length.
