Abstract
Description
Technical Field
[0001] This utility model relates to the field of traffic safety protection facilities technology, and in particular to a collision avoidance device for safety management of highway bridge engineering. Background Technology
[0002] In highway and bridge engineering, crash barriers are crucial safety facilities. Their primary function is to prevent out-of-control vehicles from veering off the road or bridge surface, thereby minimizing the severity of accidents. Traditional crash barriers, such as concrete guardrails, absorb collision energy mainly through the strength and deformation of their own structure. However, when these facilities are impacted, they often subject the vehicles and occupants to significant impact loads, and may suffer irreversible damage, resulting in high repair or replacement costs and long lead times. Existing solutions involve adding independent energy-absorbing buffer structures, such as aluminum foam, rubber pads, or metal energy-absorbing boxes, in front of the crash barrier to dissipate more collision energy through plastic deformation and reduce damage to the crash barrier itself and the vehicle. While these measures improve the buffering effect to some extent, they usually require modification of the existing crash barrier structure or complex anchoring installation, making construction inconvenient and adaptable. This is especially true when upgrading and reinforcing existing bridge or road guardrails, which often results in long construction periods and high costs. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] The following is combined Figures 1-4 This utility model describes a safety management and anti-collision device for highway bridge engineering.
[0019] In one embodiment, a safety management anti-collision device for highway bridge engineering includes: 100mm anti-collision wall; The installation mechanism 200 includes a connecting plate 210 disposed on the top of the crash barrier 100, an installation plate 260 fixedly connected to the bottom of the connecting plate 210, a slider 220 slidably connected to the top of the connecting plate 210, and a positioning plate 240 fixedly connected to the lower end of the slider 220 through the connecting plate 210. The buffer mechanism 300 includes a liquid storage shell 310 fixedly connected to the side of the mounting plate 260 away from the anti-collision wall 100, and a mounting bracket 330 provided on the other side of the liquid storage shell 310. A buffer roller 390 is rotatably connected to the inner side of the mounting bracket 330.
[0020] The installation mechanism 200 enables the installation of the buffer mechanism 300, facilitating the installation of the anti-collision device above the existing anti-collision wall 100 without requiring modification of the existing anti-collision wall 100. This simplifies operation and enhances practicality.
[0021] like Figure 2 , Figure 3 and Figure 4 As shown, a squeezing plate 340 is slidably connected to the inner wall of the liquid storage shell 310, and a connecting rod 350 is fixedly connected to the surface of the mounting bracket 330. The other end of the connecting rod 350 passes through the liquid storage shell 310 and is fixedly connected to the surface of the squeezing plate 340.
[0022] A spring 360 is fitted onto the surface of the connecting rod 350. One end of the spring 360 is fixedly connected to the surface of the mounting bracket 330, and the other end of the spring 360 is fixedly connected to the surface of the liquid storage shell 310.
[0023] A liquid storage cavity is formed between the side of the extrusion plate 340 away from the connecting rod 350 and the inner wall of the liquid storage shell 310. The liquid storage cavity is filled with water. A water injection hole is provided on the top of the liquid storage shell 310, and a sealing plug is provided inside the water injection hole.
[0024] The surface of the mounting bracket 330 has two symmetrically distributed spray holes 370. The inner wall of the liquid storage chamber is fixedly connected to a connecting pipe 320. The other end of the connecting pipe 320 passes through the extrusion plate 340 and the liquid storage shell 310 in sequence and is slidably connected to the inner wall of the spray hole 370.
[0025] The surface of the connecting pipe 320 is provided with a connecting groove 380 that communicates with the liquid storage chamber, and a one-way valve is provided inside the connecting pipe 320.
[0026] When a collision occurs, the object first contacts the buffer roller 390. During this process, the buffer roller 390 can be squeezed and rotated to consume part of the impact force, guide the object to avoid further impact, and under the action of the collision pressure, push the buffer roller 390 to move the mounting frame 330 towards the mounting frame 330. During this process, the squeezing plate 340 can be moved synchronously through the connecting rod 350, thereby squeezing the water stored inside the liquid storage shell 310. During this process, the impact force can be used to squeeze the water to consume part of the impact force, and the water can be injected into the interior of the connecting pipe 320 through the connecting groove 380 and discharged through the one-way valve and the spray hole 370, so that it can be sprayed on the surface of the object to avoid the fire caused by friction overheating. At the same time, the spring 360 can be squeezed during this process and the impact force can be further consumed. The spring 360 is set to maintain the position of the mounting frame 330 in its normal state.
[0027] like Figure 1 , Figure 2 and Figure 3As shown, the surface of the connecting plate 210 is provided with uniformly distributed through holes 230, and the surface of the connecting plate 210 is provided with a limiting screw 270. The lower end of the limiting screw 270 passes through the slider 220 and the adjacent through hole 230 in sequence and is provided with a limiting nut.
[0028] The surface of the positioning plate 240 is provided with expansion bolts 250, and the other end of the expansion bolts 250 passes through the positioning plate 240 and extends into the interior of the crash barrier 100.
[0029] Place the connecting plate 210 on the crash barrier 100, so that the crash barrier 100 is located between the mounting plate 260 and the positioning plate 240. Move the slider 220 to drive the positioning plate 240 to cooperate with the mounting plate 260 to clamp onto the crash barrier 100. Then, the limiting screw 270 passes through the slider 220 and is inserted into the through hole 230. The limiting screw 270 is then fixed with the limiting nut. Finally, the expansion bolt 250 passes through the positioning plate 240 and is inserted into the interior of the crash barrier 100 for further fixation.
[0030] Working principle: The connecting plate 210 is placed on the crash barrier 100, so that the crash barrier 100 is located between the mounting plate 260 and the positioning plate 240. The sliding block 220 moves the positioning plate 240 to cooperate with the mounting plate 260 to clamp onto the crash barrier 100. Then, the limiting screw 270 passes through the sliding block 220 and is inserted into the through hole 230, and is fixed with the limiting nut. Finally, the expansion bolt 250 passes through the positioning plate 240 and is inserted into the interior of the crash barrier 100 for further fixation. When a collision occurs, the colliding object first contacts the buffer roller 390. During this process, the buffer roller 390 can be squeezed and rotated, thereby absorbing part of the impact force, guiding the colliding object to avoid further impact, and... Furthermore, under the action of collision pressure, the buffer roller 390 is pushed to move the mounting frame 330 towards the mounting frame 330. During this process, the extrusion plate 340 can be moved synchronously through the connecting rod 350, thereby squeezing the water stored inside the liquid storage shell 310. During this process, the impact force can be used to squeeze the water, thereby consuming part of the impact force. The water can be injected into the interior of the connecting pipe 320 through the connecting groove 380 and discharged through the one-way valve and the spray hole 370, thereby spraying it on the surface of the colliding object to avoid the phenomenon of fire caused by friction overheating. At the same time, the spring 360 can be squeezed during this process, and the impact force can be further consumed. The spring 360 is set to maintain the position of the mounting frame 330 under normal conditions.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
