Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to an aluminum alloy bridge. Background Art

[0002] A rigid structural system that closely supports cables and is composed of trough-type, tray-type or stepped straight sections, bends, tees, cross-sections, supports (arm-type brackets), hangers, etc. is called a cable tray. Currently, some cable trays are inconvenient to use. For example, during use, due to its simple internal structure, the cables cannot be separated and placed after being laid inside the tray. This not only easily leads to disorder of the internal cables, but also is inconvenient for later maintenance. At the same time, although the current cable tray brackets are equipped with seismic-resistant structures, most of them are only equipped with simple shock-absorbing pads, and the shock-absorbing effect is general, and the safety and stability of the cable tray cannot be guaranteed.

[0003] The publication (announcement) number is CN219874899U, which discloses an aluminum alloy bridge, including a support plate, a cover plate fixed to the top of the support plate by bolts, a screw rod threadedly connected to the top of the cover plate, and a knob fixed to the top of the screw rod. The utility model is provided with a support plate, a cover plate, a screw rod, a knob, a limit plate, an upper limit block, a lower limit block and a shock absorbing assembly. In the process of using this cable bridge, after the cable is laid inside the support plate, under the action of the upper limit block and the lower limit block, multiple cables can be separated, which not only facilitates the later search and maintenance of the cable, but also avoids the situation that the heat generated by the use of multiple cables cannot be discharged after being entangled and attached, thereby causing a fire. Moreover, under the action of the shock absorbing assembly, the bridge as a whole can be buffered and damped, thereby solving the problem that the seismic performance of the current seismic-resistant bracket is limited and the safety and stability of the bridge cannot be guaranteed.

[0004] Although the above scheme can be used to separate and place cables and improve the seismic protection effect, most of the separation components are fixed synchronously with the cover plate and have a limited adjustment range. It is inconvenient for the equipment to dismantle the cables for maintenance, and the disassembly and assembly of the cover plate requires operating the bolts one by one at multiple points. The complete disassembly and assembly of the cover plate by the equipment is cumbersome and laborious. For this reason, we propose an aluminum alloy bridge. Utility Model Content
