Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision of highway bridges, in particular to an anti-collision device for highway bridges. Background Art

[0002] With the rapid development of my country's economy, various large-scale highway bridges are constantly being built. However, as a result, traffic safety accidents caused by cars losing control and crashing into bridges are also increasing, causing significant losses to people's lives and property. In actual applications, in order to reduce the damage to bridges and cars caused by car-bridge crashes, guardrails are often installed on both sides of the bridge lanes to forcibly stop out-of-control vehicles.

[0003] The existing Chinese utility model patent with reference announcement number: CN217378694U discloses an anti-collision device for highway bridges, which belongs to the technical field of anti-collision of highway bridges, including a column, a reinforcement component is installed on one side of the bottom of the column, and an auxiliary component is opened on one side of the column. The utility model provides a reinforcement component, and the pile column is driven into the ground through a connecting plate, so that the column can be initially reinforced, and then the insertion rod is driven to rotate through the slot hole at the top of the insertion rod, and the insertion rod can be moved downward under the meshing connection between the insertion rod and the pile column. During the downward movement of the insertion rod, the insertion block will be squeezed, so that the two insertion blocks can extend from the pile column from both sides and insert into the soil, thereby increasing the grip strength of the pile column and making the column installation more secure; the utility model provides an auxiliary component, and drives the threaded column to rotate, so that the support frame can be limited and slide down, so that the bottom end of the support frame is supported on the ground, which can play a role of auxiliary support for the column, and can resist the column from the outside to enhance the anti-collision ability of the column.

[0004] Although the above-mentioned anti-collision device for highway bridges solves the problem that the connection between the device and the ground is not firm enough and the grip of the device is poor, which easily causes the device to fall off the ground when hit, by setting reinforcement components and auxiliary components, the buffering effect of the above-mentioned equipment after being hit is insufficient, and it is easy to cause damage to the device or injury to vehicle occupants due to the large impact force.

[0028] Specifically, the support plate 1 can be auxiliary supported by two support blocks 11 on one side of the support plate 1, and the base plate 12 can be fixed at a specified position by the fixing bolts 14 inside the fixing groove 13, thereby improving the practicality of the anti-collision device for highway bridges.

[0030] Specifically, the two damping springs 21 on one side of the connecting plate 2 can achieve a buffering effect, the buffer plate 23 on one side of the mounting plate 22 can achieve a secondary buffering effect, and the connecting ring 3 can be supported and fixed by the support rod 25 inside the support groove 24.

[0031] The outer side of the support rod 25 is movably connected with a connecting ring 3, the outer side of the connecting ring 3 is fixedly installed with a buffer ring 31, the buffer ring 31 is fixedly installed with a buffer spring 32 around it, the outer side of the buffer spring 32 is fixedly installed with a supporting ring 33, and the outer side of the supporting ring 33 is fixedly installed with a protective ring 34.

[0032] Specifically, the buffer ring 31 on the outside of the connecting ring 3 can achieve a buffering effect, and the buffer spring 32 on the outside of the buffer ring 31 can achieve a secondary buffering effect, thereby improving the buffering effect of the anti-collision device for highway bridges. The outside is supported by the support ring 33, and the outermost side is protected by the protective layer 44 on the outside of the support ring 33.

[0033] A fixing plate 4 is fixedly mounted on the top of the supporting plate 1 , and a flexible steel plate 41 is fixedly mounted on the top of the fixing plate 4 .

[0034] A wrapping layer 42 is fixedly mounted on one side of the flexible steel plate 41 , and the wrapping layer 42 is in a “C” shape.

[0035] A baffle 43 is fixedly mounted on one side of the wrapping layer 42 , and a protective layer 44 is fixedly mounted on one side of the baffle 43 .

[0036] Specifically, the flexible steel plate 41 on the top of the fixed plate 4 can play a rainproof role, avoiding the problem of the buffer component being rusted due to rainwater, thereby affecting the buffer effect. The protective layer 44 on one side of the baffle 43 can play a buffering role.

[0037] Working principle: First, the anti-collision device for highway bridges can be fixed at a specified position through the fixing bolts 14 inside the fixing groove 13 at the top of the bottom plate 12, and the support plate 1 can be auxiliary supported by the two support blocks 11, thereby improving the stability and supporting force of the anti-collision device for highway bridges. When the anti-collision device for highway bridges is hit, the protective ring 34 on the outside of the support ring 33 can have a buffering effect, and the buffer spring 32 inside the support ring 33 can have a buffering effect. The buffer ring 31 inside the buffer spring 32 performs secondary buffering, thereby improving the buffering effect and impact resistance of the anti-collision device for highway bridges. Due to the active connection between the connecting ring 3 and the support rod 25, when hit, the connecting ring 3 rotates on the outside of the support rod 25, so as to guide the impact, thereby having a buffering effect, thereby improving the protective effect of the anti-collision device for highway bridges. The support groove 24 supports the support rod 25, and the buffer plate 23 on one side of the support groove 24 can play a buffering effect. The mounting plate 22 on one side of the buffer plate 23 is used for supporting and connecting. The contraction of the two damping springs 21 on one side of the mounting plate 22 can buffer the impact of the anti-collision device for the highway bridge. The four-layer buffering of the damping spring 21, the buffer plate 23, the buffer ring 31 and the buffer spring 32 improves the buffering effect, avoids the problem of damage to the vehicle and the device and injury to personnel after the collision due to insufficient buffering effect, improves the practicability and protective effect of the anti-collision device for the highway bridge, and the flexible steel plate 41 on the top of the fixed plate 4 can play a rainproof effect, avoids the problem of rainwater corroding the buffer structure and causing a reduction in the buffering effect. When a collision occurs, the protective layer 44 fits the vehicle for protection, and the baffle 43 pushes the flexible steel plate 41 to deform, avoids affecting shock absorption and buffering, and improves the practicability of the anti-collision device for the highway bridge.
