Description

Technical Field

[0001] The utility model relates to the field of municipal bridges, in particular to a municipal bridge buffer device. Background Art

[0002] A municipal bridge refers to a spanning structure built on urban roads, railways and other transportation routes to overcome obstacles such as rivers, ditches, roads, and railways. It has the function of carrying vehicles and pedestrians, and also needs to consider factors such as aesthetics and environmental protection. When a municipal bridge expands and contracts due to external reasons such as temperature, load or earthquake, the lack of a buffer device will cause the bridge to twist, deform, or even be seriously damaged. The buffer device can absorb the expansion and contraction deformation of the bridge through expansion and contraction, so that the bridge will not be damaged due to deformation, ensuring the service life and safety of the bridge.

[0003] After searching, a municipal bridge buffer device with a publication number of CN213086549U is found, which specifically discloses a municipal bridge buffer device, a municipal bridge buffer device, including a support platform, a sound-absorbing cabin installed on the inner wall of the support platform A, a damper installed on one side of the support platform surface, and there are two dampers, and concave blocks are welded on the left and right ends of the damper surface, and the concave blocks are welded to the side of the support platform close to the damper, and a spring A is installed on the damper surface, and the spring A is welded on the inner wall of the concave block, and a load-bearing block is installed on the inner wall of the support platform, which is convenient for adopting multiple buffer structures for buffering and facilitating timely absorption of generated noise. Under the action of multiple buffering force distribution structures on the bridge, the service life of the equipment is greatly extended, and after the sound-absorbing cabin absorbs the noise in time, the noise problem is greatly reduced.

[0004] During the use of existing municipal bridge buffer devices, when the municipal bridge is impacted by external factors, the impact force is not only felt at one position, but the impact force will spread to the entire municipal bridge. If the buffer device only buffers the bridge deck, the other pier positions will still rely on the material of the municipal bridge itself to resist. In addition, the above-mentioned comparative cases also lack other means to enhance the buffering capacity of the municipal bridge. As a result, hidden faults may occur in the piers and other positions of the municipal bridge under long-term use, requiring the municipal department to take great pains to maintain them, thereby increasing maintenance costs.

[0005] Therefore, it is necessary to invent a municipal bridge buffer device to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a municipal bridge buffer device, which can achieve secondary buffering and weakening of the impact force transmitted by the municipal bridge through the pier bracket, buffer frame, torsion spring, side tensile seat, anti-detachment buffer chain and strong chain link, reduce the relative displacement of the pier bracket and the bridge frame body, prevent the bridge frame body from falling off the pier bracket, and effectively prevent the structural fatigue and corrosion of the bridge, extend the service life of the bridge, and reduce the probability of hidden faults in the piers and other positions of the municipal bridge, thereby reducing the maintenance cost of the municipal department for the municipal bridge, so as to solve the problem that when the municipal bridge buffer device in the prior art is used, when the municipal bridge is impacted by external factors, not only one position is affected by the impact force, but the impact force will spread to the entire municipal bridge. If the buffer device only buffers the bridge deck, the other pier positions still rely on the material of the municipal bridge itself to resist, and the above-mentioned comparative case also lacks other means to enhance the buffering capacity of the municipal bridge. In this way, hidden faults will occur in the piers and other positions of the municipal bridge under long-term use, requiring the municipal department to take the trouble to maintain it, thereby increasing the maintenance cost.

[0016] 1. The utility model is provided with a pier bracket, a buffer frame, a torsion spring, a side tensile seat, an anti-slip buffer chain and a strong chain link.
