Description

Technical Field

[0001] The utility model relates to the field of bridge frames, in particular to an earthquake-resistant bridge frame which is convenient for cable classification. Background Art

[0002] At present, a Chinese utility model with the announcement number CN220042875U discloses an earthquake-resistant bridge for cable installation, including two mounting plates, a first horizontal plate and a second horizontal plate, the mounting plates are provided with a shock-absorbing assembly, the mounting plates are provided with an auxiliary assembly, the shock-absorbing assembly includes two connecting plates fixedly mounted on the top of the first horizontal plate, the bottom of the inner walls of the two connecting plates are fixedly mounted with rubber columns, the interiors of the two connecting plates are fixedly mounted with fixing plates, and the tops of the two fixing plates are fixedly mounted with support rods. The earthquake-resistant bridge for cable installation is equipped with a shock-absorbing assembly, which can buffer and resist earthquakes when the bridge is vibrated, reduce the phenomenon of loosening of the bridge and the ceiling installation due to vibration, facilitate the normal operation of the cable, and improve the service life of the cable. Auxiliary assemblies are installed to clamp and store the cables, which is convenient for the staff to perform maintenance later.

[0003] Existing cable bridges are inconvenient to maintain. Generally, the shell and cover of the cable bridge are fixed and installed by screws. When maintaining it, it is necessary to use a screwdriver to disassemble and assemble the screws. The disassembly and assembly process is relatively cumbersome, which increases the workload, reduces the efficiency of maintenance, and is inconvenient to use. The distance between the bars cannot be adjusted. In order to classify the cables, the cable bridge generally separates the cables with distribution poles to facilitate later maintenance and reduce interference between the cables. However, the distribution poles are fixedly connected to the cable bridge, resulting in a fixed distance between the distribution poles. During use, different types of cables have different numbers and require different sizes of space. The spacing between the distribution poles is fixed, resulting in a large number of cables of the same type, which are difficult to place. A small number of cables wastes the use space, making it difficult to meet the use requirements, and reducing practicality and applicability. In order to solve the above-mentioned problems, we propose an earthquake-resistant cable bridge that is convenient for cable classification. Utility Model Content
