TECHNICAL FIELD

[0001] The present application relates to a bridge protection device with shock absorption function. BACKGROUND

[0002] Bridge is a kind of closed metal device composed of copper and aluminum bus column, which is used to distribute large power to each element of the distribution system. In the indoor low-voltage power transmission trunk project, it has been increasingly replaced by wire and cable. Due to the need of power supply of buildings, factories and other buildings, and the trend of increasing year by year, the original circuit wiring method, i.e. pipe penetrating method, brings many difficulties in construction, and it is almost impossible to make it simple when changing the power distribution system. However, if the bridge is used, it is very easy to achieve the purpose, and it can also make the building more beautiful. From the economic point of view, compared with the cable, the price of the bridge itself is higher, but compared with the various accessories for wiring and the entire power system, the use of the bridge can make the construction cost much cheaper.

[0003] With the understanding and application of the bridge, the application of the bridge is more and more widely, but since the bridge is mostly a frame structure supported by metal materials, the quality of a single bridge is large, and the space occupied is also not small, so that the transportation of the bridge is very inconvenient. The existing transportation device has complex structure, cannot be adjusted, has poor shock absorption effect, the bridge is easy to be damaged in the transportation process, and is mostly one-time transportation structure, so the transportation cost is high. Therefore, a bridge protection device with shock absorption function is born. SUMMARY

[0004] The purpose of the present application is to solve the above problems of the prior art, and to provide a bridge protection device with shock absorption function.

[0006] As a further improvement, the limiting column between the side fixing plate and the main fixing plate is sleeved with a spring, and due to the force of the spring, the side fixing plate is automatically moved outward without force, so that the internal space of the whole protection device is maximized, at this time the bridge is placed in the internal space of the protection device and then tightened to realize the fixation of the bridge, and the whole protection device does not need to use other auxiliary tools during adjustment, greatly reducing the operation difficulty of the protection device and reducing the use cost.

[0007] As a further improvement, the free end of the fastening screw is connected with the tightening head abutting on the side wall of the main fixing plate, which is simple in structure, convenient in operation and convenient to use.

[0008] As a further improvement, the opposite surfaces of the side fixing plate and the other side fixing plate are both provided with grooves.

[0009] As a further improvement, the grooves are both provided with damping blocks, and the damping blocks are both fixed in the grooves by a plurality of damping elastic components.

[0010] As a further improvement, the surface of the damping block is coated with a wear-resistant layer, and the damping elastic component includes a compression spring, a rubber layer and a silica gel layer, which prevents damage and wear caused by bumps during transportation and plays a buffering protection role.

[0011] As a further improvement, the driven clamping groove and the driving clamping groove are both designed to be inclined, which can realize the gradual contraction of the limiting column through the plug-in mode, so as to realize the tightening and loosening of the side fixing plate and achieve the purpose of adjusting the internal space of the protection device according to the size of the bridge.

[0012] As a further improvement, the inclination angle of the inner wall of the driven clamping groove is equal to the inclination angle of the outer wall of the driving clamping groove. Advantages

[0013] The device is different from the traditional split type protection device, and each part of the split type protection device is designed in a separated manner, which needs to be assembled by the staff according to the requirements during use, and the structure is complex, the assembly process is long, the assembly difficulty is large, the carrying is difficult, the bridge transportation is very inconvenient, and the transportation efficiency is greatly reduced.

[0014] The device does not need other auxiliary tools during installation, is convenient to adjust, greatly reduces the operation difficulty of the protection device, reduces the use cost, is simple in structure, can be repeatedly used after disassembly after transportation, and greatly reduces the transportation cost.

[0015] The device does not need to be assembled, has fewer installation steps during transportation and use, prevents damage and wear caused by bumps during transportation by using the damping elastic component, and plays a buffering protection role.

[0016] The device is fixed in structure when not in use, is convenient to stack and store, is stable in structure, is designed to be adjustable, can be applied to the transportation of more bridge frames of different specifications, makes the transportation of the whole bus duct more convenient, is convenient to popularize and use, and effectively guarantees the stability of the internal structure of the bridge frame.
