AI Technical Summary
When the reinforcement mechanism of the existing bridge anti-collision facilities is impacted, a single reinforcement mechanism cannot cause multiple reinforcement mechanisms to shrink at the same time, resulting in poor anti-collision capabilities and unable to effectively ensure the stability and safety of the bridge structure.
A reinforcement mechanism for a bridge anti-collision facility is designed. By setting a plurality of fixed plates on the outer side of the bridge body, each fixed plate is equipped with a damper, a connecting plate, a return spring and a support plate. The support plate is slidably connected to the sliding sleeve and connected by a compression spring, each anti-collision block is achieved synchronously when impacted, absorbs impact force, and protects the damper through the return spring to avoid damage.
When the bridge is hit, multiple reinforcement mechanisms are simultaneously contracted, which enhances the anti-collision capability, protects the damper, avoids mutual compression and damage from the anti-collision blocks, improves the reinforcement capacity of the anti-collision facilities of the bridge, and ensures the stability and safety of the bridge structure.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge anti-collision, in particular to a reinforcement mechanism of bridge anti-collision facilities. Background Art
[0002] Bridges, as a road connecting structure, are very common in daily life. Usually, bridges are composed of foundations, piers and spans. In some areas with dense road networks, or in order to meet the requirements of road lines, piers will appear on the road below the span. Since the piers are the supporting structure of the span, when the structure of the piers is disturbed, it will affect the stability of the span structure. When the piers are on a road with a large number of vehicles passing, it is easy for vehicles to collide with the piers, which greatly threatens the safety of the bridge structure. Therefore, bridge anti-collision facilities are needed; the reinforcement mechanism of some existing bridge anti-collision facilities is to wrap the bridge body through multiple anti-collision blocks. When the anti-collision facility is hit, only the reinforcement mechanism on a single side is hit, and it cannot drive multiple reinforcement mechanisms to shrink inward at the same time. The anti-collision ability is poor, and the reinforcement ability of the anti-collision facility cannot be guaranteed. Utility Model Content
[0003] In view of this, the utility model provides a reinforcement mechanism for a bridge anti-collision facility, which can achieve simultaneous force contraction through the connection between each reinforcement mechanism when impacted, buffer the impact force, improve the anti-collision ability of the anti-collision facility, and ensure the reinforcement ability of the anti-collision facility.
[0004] In order to solve the above technical problems, the utility model provides a reinforcement mechanism for bridge anti-collision facilities, including a bridge body, a plurality of fixed plates evenly arranged on the outer surface of the bridge body, a damper is arranged in the middle of each fixed plate, a connecting plate is arranged on the surface of each damper, two return springs are arranged on the inner side of each connecting plate, support plates are arranged on both sides of each connecting plate, two adjacent support plates are slidably connected to the inside of a sliding sleeve, and a compression spring connected to the support plate is arranged inside each sliding sleeve. When the bridge body encounters a collision accident, the anti-collision block will be forced to retract inward. The damper thereby contracts and absorbs the impact force. The return spring can ensure the elastic capacity of the reinforcement mechanism when it is subjected to impact force, thereby preventing the damper from being directly damaged by the impact. When the anti-collision block on one side is hit, since the limit block is slidably connected in the sliding sleeve, the connection between the anti-collision blocks is realized, and they can simultaneously contract inward when hit, thereby increasing the resistance to the impact force and ensuring the reinforcement capacity of the bridge anti-collision facility. When the anti-collision blocks contract inward at the same time, the compression spring can be used to realize the back and forth movement of the anti-collision blocks, thereby preventing the anti-collision blocks from squeezing and interfering with each other and being damaged when contracting inward.
[0005] The damper on the same fixed plate is located between two return springs, providing protection for the damper to prevent excessive impact force from affecting the normal use of the damper.
[0006] The surfaces of the connecting plates are all provided with connecting blocks, the connecting blocks are provided with anti-collision blocks, and the anti-collision blocks are connected to the supporting plates.
[0007] The anti-collision block is divided into an anti-collision base and an anti-collision pad. The anti-collision pad is located on the outside of the anti-collision base, providing anti-collision capability for the bridge body to prevent damage to the bridge body.
[0008] The anti-collision blocks are in arc shape, and the shapes of each anti-collision block correspond to each other, ensuring the wrapping of the bridge body and achieving the protection effect of the bridge body.
[0009] There are four fixing plates, and the four sides of each fixing plate are connected to the bridge body through fixing rods. Workers can use the fixing rods to connect and fix the fixing plates to the surface of the bridge body.
[0010] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:
[0011] 1. When the utility model is used, the connection between each reinforcement mechanism can realize simultaneous force contraction when it is hit, so as to buffer the impact force, improve the anti-collision ability of the anti-collision facility, and ensure the reinforcement ability of the anti-collision facility.
[0012] 2. When the present invention is in use, the damper on the same fixed plate is located between the two return springs, which provides protection for the damper and prevents excessive impact force from affecting the normal use of the damper.
[0013] 3. When the utility model is used, the anti-collision block is divided into an anti-collision base and an anti-collision pad. The anti-collision pad is located on the outside of the anti-collision base to provide anti-collision capability for the bridge body and avoid damage to the bridge body.
[0014] 4. When the utility model is used, the anti-collision block is in an arc shape, and the shapes of each anti-collision block correspond to each other, which ensures the wrapping of the bridge body and achieves the protection effect of the bridge body. BRIEF DESCRIPTION OF THE DRAWINGS
