Due to the limited construction and installation area, it is often necessary to install multiple parallel or multi-layer cable trays to meet the needs of the operation. In addition, during the construction and installation process, the cover of the cable tray is mostly made of a whole piece of original plate, so that the staff often have to remove the cover when inspecting the inside of the cable tray. When the cable tray is close to the building on top of it, there is insufficient space for disassembly of the cover, which makes it difficult to remove the cover. At the same time, the work of disassembling and carrying the cover up and down is time-consuming and labor-intensive, affecting the efficiency of inspection and maintenance. Utility Model Content

[0003] The purpose of the utility model is to provide a cable bridge that can be opened quickly to address the problems that when workers are performing maintenance inside the bridge, they often have to remove the cover plate.

Through the arrangement of the support plate 4 and the bearing plate 5, the cable can be hoisted and placed in the inner cavity of the bridge, so as to facilitate the inspection and maintenance of the staff, and a number of heat dissipation holes distributed at equal distances are opened through the support plate 4 and the bearing plate 5, which improves the heat dissipation performance, and the bearing plate 5 is provided with a plurality of evenly distributed and laterally arranged partition columns 501. Through the arrangement of the partition columns 501 on the bearing plate 5, the cables can be separated and placed, which is convenient for the staff to inspect and improve the heat dissipation performance, and the front and rear ends of the bottom end surface of the bridge cover 1 on both sides of the support plate 4 are symmetrically provided with limit columns 8, and the bottom of the bridge cover 1 is provided with a bridge bottom plate 2 parallel to it, and the bridge bottom plate 2 Bridge side panels 3 are symmetrically arranged on both sides, and the bridge side panels 3 and the bridge bottom panel 2 are an integrally formed structure. Fixed columns 6 are symmetrically arranged on the front and rear ends of the inner side end surfaces of the bridge side panels 3. The setting of the fixed columns 6 improves the strength of the bridge port. A fixing groove 601 for the insertion of a limiting column 8 is opened on the top end surface of the fixing column 6. The setting of the limiting column 8 on the bridge bottom panel 2 and the fixing groove 601 in the fixing column 6 on the bridge side panels 3 improves the stability of the bridge side panels 3 when they are displaced downward. A limiting rod 602 is provided in the fixing groove 601 with both ends fixedly connected to the inner side wall of the fixing groove 601. The utility model can inspect and maintain the cables in the bridge without removing the bridge cover 1, thereby avoiding the problem of insufficient disassembly space of the bridge cover 1 when the bridge is close to the building on its top, which makes it difficult to disassemble the bridge cover 1, and greatly improves the inspection efficiency.

[0020] Among them, the limit column 8 is penetrated by a limit groove 801 for the limit rod 602 to move up and down. Through the arrangement of the limit groove 801 on the limit column 8 and the limit rod 602 in the fixed column 6, the bridge side plate 3 and the bridge bottom plate 2 can be displaced downward, and at the same time, they are hung on the bottom of the bridge cover plate 1 without being separated from the connection with the bridge cover plate 1, exposing the cables on the bearing plate 5, thereby facilitating maintenance by the staff.

[0021] Among them, a mounting plate 302 extending along its length direction is provided on the top of the outer end surface of the bridge frame side plate 3, and a plurality of evenly distributed first mounting holes 303 for inserting fastening bolts 7 are penetrated through the mounting plate 302, and second mounting holes connected to the first mounting holes 303 one by one are provided on the bottom end surface of the bridge frame cover plate 1.

Through the setting of the reinforcing column 301, the strength of the bridge frame side plate 3 and the overall strength of the bridge frame are improved.

[0023] The working principle of the utility model is:

[0024] When in use, loosen the fastening bolts 7 for disassembly, and then move the integrally formed bridge frame side plate 3 and bridge frame bottom plate 2 downward, providing maintenance space for the staff, and at the same time exposing the cables on the load-bearing plate 5, so that the staff can inspect and handle the cables separated and placed on the load-bearing plate 5. The setting of the limit column 8 on the bridge frame bottom plate 2 and the fixed groove 601 in the fixing column 6 on the bridge frame side plate 3 improves the stability of the bridge frame side plate 3 when it is displaced downward. The setting of the limit groove 901 on the limit column 8 and the limit rod 602 in the fixed groove 601 can limit the displacement of the bridge frame side plate 3, and at the same time, the bridge frame side plate 3 and the bridge frame bottom plate 2 can be suspended at the bottom of the bridge frame cover plate 1. The utility model can inspect and maintain the cables in the bridge frame without removing the bridge frame cover plate 1, avoiding the problem of insufficient disassembly space of the bridge frame cover plate 1 when the bridge frame is close to the building on its top, which makes it difficult to disassemble the bridge frame cover plate 1, thereby greatly improving the maintenance efficiency.
