Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision structures, in particular to an anti-collision structure. Background Art

[0002] Bridges generally refer to structures erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, supports, and auxiliary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the supporting locations of the span structure and piers or abutments.

[0003] The existing bridge piers are an important part of the bridge, and the anti-collision walls used for bridge piers are usually hard anti-collision, which cannot protect against subsequent impacts on the piers. When the impactor breaks through the hard anti-collision structure, it will directly contact the pier, and the contact points will be relatively concentrated, which will cause damage to the internal structure of the bridge pier and affect the safety of the bridge. Therefore, the existing bridge piers lack a buffer anti-collision structure. For this reason, we provide an anti-collision structure. Utility Model Content

[0004] The utility model aims to solve the defect that the bridge pier column in the prior art lacks a buffer type anti-collision structure and provides an anti-collision structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-collision structure, comprising: a main body mechanism, the main body mechanism comprises a roadbed, a pier column is penetrated inside the roadbed, the pier column is fixedly connected to the roadbed, an anti-collision mechanism is arranged on one side of the pier column, the anti-collision mechanism comprises an arc-shaped plate, a damping rod is arranged on one side of the arc-shaped plate, one end of the damping rod is fixedly connected with a fixing plate 1, the fixing plate 1 is fixedly connected to the arc-shaped plate, the end of the damping rod away from the fixing plate 1 is fixedly connected with a fixing plate 2, a spring 1 is sleeved on the outer surface of the damping rod, the two ends of the spring 1 are respectively fixedly connected to the outer surfaces of the fixing plate 1 and the fixing plate 2, a connecting column is arranged on the side of the fixing plate 2 away from the damping rod, the connecting column is fixedly connected to the fixing plate 2, one end of the connecting column is fixedly connected with a contact plate, and a foam plate is fixedly connected to the side of the arc-shaped plate away from the damping rod.

[0006] As a preferred embodiment, auxiliary mechanisms are provided on both sides of the pier column, and the auxiliary mechanisms include fixing rods, and the fixing rods are placed in strip grooves opened on the roadbed.

[0007] As a preferred implementation manner, the fixing rod is fixedly connected to the roadbed, and one end of the fixing rod is sleeved with a sleeve block 1.

[0008] As a preferred implementation, the sleeve block 1 is fixedly connected to the fixing rod, and the sleeve block 2 is sleeved on the outer surface of the fixing rod.

[0009] As a preferred implementation, the sleeve block 2 is slidably connected to the fixing rod, and the outer surface of the fixing rod is sleeved with a spring 2.

[0010] As a preferred embodiment, the two ends of the spring 2 are respectively fixedly connected to the outer surfaces of the sleeve block 1 and the sleeve block 2, and the top of the sleeve block 2 is fixedly connected to a vertical block.

[0011] As a preferred implementation, a connecting plate is fixedly connected to the top of the vertical block, and the connecting plate is fixedly connected to the arc plate.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The utility model can protect the piers of the bridge by arranging an anti-collision mechanism, so that a small external impact will not cause damage to the piers. Since the anti-collision mechanism and the auxiliary mechanism are used in coordination, and the anti-collision mechanism will not directly contact the pier when subjected to external impact, and the external impact force will not directly act on the pier, so that the overall structure of the pier will remain intact, thereby achieving the effect of anti-collision of the pier. In addition, even if a large external impact causes the anti-collision mechanism to move more as a whole, the impact force will not be transmitted to a certain concentrated point on the outer surface of the pier. Since the pier is subjected to force as a whole and a part of the impact force is pre-absorbed by the anti-collision mechanism and the auxiliary mechanism, the damage to the pier will not be large. Therefore, the anti-collision structure for protecting the bridge piers has good use effect and practicality, can better protect the bridge piers from external impact, and makes the bridge as a whole more stable and safer.

[0026] In this embodiment, by setting up an anti-collision mechanism 2, the bridge pier 12 can be protected from frontal impact, and an arc plate 21 is provided, and the shape of the arc plate 21 is arc-shaped. Therefore, even if the arc plate 21 is in indirect contact with the surface of the pier 12, the impact force will not be concentrated on a certain point, and thus the pier 12 will not be caused internal damage. The foam plate 28 is provided to protect the outer surface of the pier 12 from being broken due to a slight collision, and thus the pier 12 will not be corroded due to damage. In addition, a damping rod 22 and a spring 25 are provided, and the damping rod 22 can generate resistance when compressed, and cooperate with the resistance generated by the compression of the spring 25 to buffer and weaken the impact force generated by the impact contact plate 27 until the impact force completely disappears.

[0027] Example 2

[0028] like Figure 1 and Figure 4 As shown, auxiliary mechanisms 3 are provided on both sides of the pier 12, and the auxiliary mechanisms 3 include a fixing rod 31, which is placed in a strip groove opened on the roadbed 11, and the fixing rod 31 is fixedly connected to the roadbed 11, and one end of the fixing rod 31 is sleeved with a sleeve block 1 32, and the sleeve block 1 32 is fixedly connected to the fixing rod 31, and the outer surface of the fixing rod 31 is sleeved with a sleeve block 2 33, and the sleeve block 2 33 is slidably connected to the fixing rod 31, and the outer surface of the fixing rod 31 is sleeved with a spring 2 34, and the two ends of the spring 2 34 are respectively fixedly connected to the outer surfaces of the sleeve block 1 32 and the sleeve block 2 33, and the top of the sleeve block 2 33 is fixedly connected with a vertical block 35, and the top of the vertical block 35 is fixedly connected with a connecting plate 36, and the connecting plate 36 is fixedly connected to the arc plate 21.

At this time, under the transmission of the contact plate 27, the connecting column 26 will drive the fixing plate 24 to compress the damping rod 22, so that the damping rod 22 generates resistance, and the fixing plate 24 will compress the spring 1 25 when compressing the damping rod 22, so that the spring 1 25 generates elastic force, and the elastic force of the spring 1 25 will react on the fixing plate 24 and cooperate with the damping rod 22. , to buffer the impact force. At the same time, when the contact plate 27 is hit, the entire anti-collision mechanism 2 will move as a whole, and under the transmission of the connecting plate 36, the sleeve block 23 will slide on the fixed rod 31. At this time, the sleeve block 23 will synchronously compress the spring 24, and then the spring 24 will generate an elastic force, and the elastic force of the spring 24 will cooperate with the elastic force of the spring 1 25 and the resistance of the damping rod 22 to buffer and weaken the external impact force, so that the pier 12 can be protected from the impact caused by the collision.
