Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof bridge frames, and more specifically, particularly relates to a combined fireproof bridge frame. Background Art

[0002] Fireproof bridges are suitable for laying power cables below 10KV, as well as control cables, lighting wiring and other indoor and outdoor overhead cable trenches and tunnels. Fireproof bridges have a frosted surface and are generally used in fire equipment distribution lines, including fire control rooms, fire pumps, fire elevators, smoke exhaust fans and automatic fire alarm systems. Except for the automatic fire alarm system, other distribution lines can use fire-resistant cables without the need for fireproof bridges. Fireproof bridges are mainly composed of fireproof boards composited with glass fiber reinforced materials and inorganic adhesives, metal skeletons and other fireproof substrates. Fireproof bridges are required to have a fire resistance time of more than 1h in underground garages.

[0003] Based on the above, the inventors have discovered the following problems: the existing fireproof bridge frames are installed and spliced ​​by tightening bolts during installation and use, but over a long period of time, the bolted joints may rust and become loose, causing inconvenience to the subsequent maintenance or overhaul of the staff, and the cables are used directly inside the bridge frame, the ventilation effect is poor, and the fireproof performance is indirectly reduced.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a combined fire-proof bridge is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a combined fireproof bridge to solve the problem that the existing bolted joints may become rusty and loose.

[0006] The purpose and effect of the combined fireproof bridge of the utility model are achieved by the following specific technical means:

[0007] A combined fireproof bridge comprises a bridge body, a fixed frame body is installed inside the bridge body, a plurality of driving fans are arranged inside the fixed frame body, a group of cable racks are arranged at both ends of the fixed frame body, a support block is fixedly installed at one end of the bridge body, and a limiting mechanism is arranged inside the bridge body.

[0008] Furthermore, the outer wall of the bridge body is provided with a plurality of ventilation holes.

[0009] Furthermore, a support groove is provided on one side of the bottom end of the bridge body, and the support block matches the support groove.

[0010] Furthermore, the limiting mechanism includes a connecting rod, a spring is sleeved on the surface of the connecting rod, a limiting block is fixedly installed on the surface of the connecting rod, the spring is located on one side of the limiting block, and a connecting block is fixedly installed on one end of the connecting rod, and an oblique stopper is fixedly installed on one end of the connecting block.

[0011] Furthermore, a groove is provided on one side of the bridge body, a limiting groove is provided inside the groove, the connecting block matches the groove, and the oblique stopper matches the limiting groove.

[0012] Furthermore, a group of handles are connected and installed on the outer walls on both sides of the bridge body, and one end of the handle passes through the bridge body to the inside and is fixedly connected to one end of the connecting rod.

[0013] Furthermore, an inclined surface is arranged at the inner bottom end of the bridge body, and a plurality of groups of flow guide holes are opened on both sides of the bridge body, and the flow guide holes are located on one side of the inclined surface.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Through the design of the ventilation holes, when the staff uses the bridge, they can start the driving fan to expel the hot air inside, and effectively circulate the air inside to dissipate the heat, which indirectly improves the heat dissipation efficiency, avoids the internal temperature of the bridge being too high to affect the work efficiency, and indirectly improves the use efficiency, which is very simple.

[0016] Through the cooperation between the support groove and the support block, the bridge frame can be effectively supported during splicing and installation to avoid breakage and the like, which indirectly brings convenience to the staff.

[0017] Through the cooperation between the connecting block, the groove, the oblique stopper and the limit groove, the staff can directly install the connecting block into the inside of the groove during installation, and then the oblique stopper will automatically snap into the inside of the limit groove under the action of the spring, so that the bridge can be limited and fixed. At the same time, when the staff needs to inspect or maintain, they can directly pull the handle to move the connecting block, and then the oblique stopper can be detached from the inside of the limit groove, so that the bridge can be disassembled. The operation steps are very simple, which avoids the need for staff to use tools for disassembly, and this design greatly increases the practicality.

[0018] Through the design of the guide holes, dust or impurities inside the bridge can be effectively discharged through the guide holes through the inclined surface under the action of gravity, which effectively avoids the accumulation of dust inside after long-term use, which is very simple.
