Technical Field

[0001] The utility model belongs to the technical field of highway engineering, in particular to a crash barrier for highway engineering. Background Art

[0002] The crash barriers used in highway projects are designed to ensure driving safety and prevent serious accidents caused by vehicles deviating from the road, running off the road, or colliding with road facilities.

[0003] According to the disclosure, a crash barrier for highway engineering (CN 214401556 U) includes a first fixed plate and a second fixed plate, wherein the second fixed plate is arranged on the right side of the first fixed plate, and both sides of the bottom of the first fixed plate and the second fixed plate are fixedly connected with columns, and the bottom of the columns is fixedly connected with a mounting plate, and the front surfaces of the first fixed plate and the second fixed plate are fixedly connected with corrugated plates. The crash barrier for highway engineering is to ensure driving safety and prevent vehicles from deviating from the road. In daily use, the crash barrier may be impacted by vehicle collisions, which affects its protective function and increases the damage and injury caused by accidents. Through the mutual cooperation between the columns, the first fixed plate and other components, it is difficult to slowly absorb the impact force when the crash plate is hit, so that the impact force is gradually released, and it is difficult to make the collision process more gentle, reducing the damage and injury caused by accidents, which needs to be improved. Utility Model Content

[0004] The utility model aims to provide a crash barrier for highway engineering. Through the mutual cooperation among the spring telescopic rod, crash barrier plate, sliding block, round rod, diagonal rod and other components inside the shock absorbing device, when the crash barrier plate is hit, it will be squeezed backwards and squeeze the spring telescopic rod and the diagonal rod. The two diagonal rods will drive the sliding block to move left and right, and pull the spring one located in the middle to shake left and right, so that the impact force is slowly absorbed through the elastic force, and the impact force is gradually released, so that the impact process is more moderate, the damage and injury caused by the accident are reduced, and the existing problems are solved.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model discloses a crash barrier for highway engineering, comprising a base plate, a pillar fixedly connected to the bottom of the base plate, a shock absorbing device arranged on the side of the base plate, the shock absorbing device comprising a support plate, the side of the support plate fixedly connected to the side of the base plate, a spring telescopic rod fixedly connected to the side of the support plate, a base fixedly connected to the side of the support plate, a round rod fixedly connected to the side of the base, a sliding block slidably connected to the circumferential surface of the round rod, an inclined rod rotatably connected to the inner wall of the sliding block, and an end of the inclined rod away from the sliding block fixedly connected to the crash barrier.

[0007] Furthermore, two sliding blocks are provided and are symmetrical to each other along the vertical center axis of the round rod. A spring 1 is slidably sleeved on the circumferential surface of the round rod. One end of the spring 1 away from the round rod is fixedly connected to the side of the sliding block. The provision of two sliding blocks is conducive to driving the middle spring 1 to move left and right, thereby reducing impact.

[0008] Furthermore, there are two spring telescopic rods, round rods, and oblique rods, and they are symmetrical to each other along the vertical center axis of the support plate. There are two bottom plates and pillars, and they are symmetrical to each other along the vertical center axis of the support plate. The two bottom plates and pillars make the device more stable and less likely to shake when standing on the ground.

[0009] Furthermore, a vertical plate is fixedly connected to the side of the support plate, a rectangular groove is opened on the side of the vertical plate, a resistance block is fixedly connected to the inner wall of the rectangular groove, a square plate is fixedly connected to the side of the anti-collision plate, a notch is opened on the side of the square plate, a spring 2 is fixedly connected to the inner wall of the notch, and a deceleration block is fixedly connected to the end of the spring 2 away from the inner wall of the notch. Such a design slows down the rebound speed of the anti-collision plate when the anti-collision plate rebounds after being hit.

[0010] Furthermore, a plurality of resistance blocks are provided and arranged along a linear array on the inner wall of the rectangular groove. The resistance blocks are located on the displacement track of the deceleration blocks, and the side surfaces of the anti-collision plate are slidably connected to the side surfaces of the vertical plate. Such a design is beneficial for the anti-collision plate to pass through the resistance blocks when it rebounds, thereby slowing down the rebound speed.

[0011] Furthermore, there are two vertical plates, which are symmetrical to each other along the vertical center axis of the anti-collision plate. The vertical plates are located on the displacement trajectory of the square plate. There are two springs and deceleration blocks, which are symmetrical to each other along the vertical center axis of the square plate. Two deceleration blocks can quickly slow down the speed during rebound.

[0012] Furthermore, the deceleration block is configured in a right-angled triangle shape, a reinforcement rod is fixedly connected to the side of the pillar, and the support plate is configured to be made of metal material. The metal support plate is hard and not easily damaged.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model realizes that when the anti-collision plate is hit, it will be squeezed backwards, squeezing the spring telescopic rod and the oblique rod, and the two oblique rods will drive the sliding block to move left and right, and pull the spring 1 in the middle to shake it left and right, so that the impact force is slowly absorbed by the elastic force, and the impact force is gradually released, making the impact process more moderate and reducing the damage and injury caused by the accident.

[0015] 2. The utility model realizes that when the anti-collision plate rebounds after being hit, the anti-collision plate drives the deceleration block to slide over the side of the resistance block through the large arc surface at the front end of the deceleration block, so that it can easily slide over the resistance block when hit. When rebounding, the arc surface at the rear end of the deceleration block is smaller, and the resistance during rebound will increase, which slows down the speed of the anti-collision plate when it rebounds, reducing the risk of collision with other vehicles or obstacles again after rebounding.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] There are two sliding blocks 36, which are symmetrical to each other along the vertical center axis of the round rod 34. A spring 37 is slidably sleeved on the circumferential surface of the round rod 34. One end of the spring 37 away from the round rod 34 is fixedly connected to the side of the sliding block 36. The two sliding blocks 36 are conducive to driving the middle spring 37 to move left and right to reduce impact.

[0028] There are two spring telescopic rods 32, round rods 34, and inclined rods 35, and they are symmetrical to each other along the vertical center axis of the support plate 31. There are two bottom plates 1 and pillars 2, and they are symmetrical to each other along the vertical center axis of the support plate 31. The two bottom plates 1 and pillars 2 make the device more stable and less likely to shake when standing on the ground.

[0029] A vertical plate 39 is fixedly connected to the side of the support plate 31, a rectangular groove 310 is opened on the side of the vertical plate 39, a resistance block 312 is fixedly connected to the inner wall of the rectangular groove 310, a square plate 311 is fixedly connected to the side of the anti-collision plate 38, a notch 313 is opened on the side of the square plate 311, a spring 2 314 is fixedly connected to the inner wall of the notch 313, and a deceleration block 315 is fixedly connected to the end of the spring 2 314 away from the inner wall of the notch 313. This design slows down the speed of the anti-collision plate 38 when it rebounds after being hit.

[0030] There are a number of resistance blocks 312 arranged along a linear array on the inner wall of the rectangular groove 310. The resistance blocks 312 are located on the displacement trajectory of the deceleration block 315. The side of the anti-collision plate 38 is slidably connected to the side of the vertical plate 39. This design is beneficial for the anti-collision plate 38 to pass through the resistance block 312 when it rebounds, thereby slowing down the rebound speed.

[0031] There are two vertical plates 39, which are symmetrical to each other along the vertical center axis of the anti-collision plate 38. The vertical plate 39 is located on the displacement trajectory of the square plate 311. There are two springs 314 and two deceleration blocks 315, which are symmetrical to each other along the vertical center axis of the square plate 311. Two deceleration blocks 315 can quickly slow down the speed during rebound.

[0032] The deceleration block 315 is set to a right-angled triangle shape, the side of the pillar 2 is fixedly connected with a reinforcement rod 4, and the support plate 31 is set to be made of metal. The metal support plate 31 is hard and not easily damaged.

[0033] A specific application of this embodiment is as follows: the present application uses the bottom plate 1 to make the device stand on the ground, and one side of the anti-collision plate 38 is regarded as the front side, facing the vehicle to be blocked. When the anti-collision plate 38 is hit, it will move backward to the side close to the support plate 31. The anti-collision plate 38 is located on one end of the spring telescopic rod 32. The anti-collision plate 38 moves backward and squeezes the spring telescopic rod 32. The spring telescopic rod 32 is squeezed and bounces left and right. The anti-collision plate 38 moves backward and squeezes the two oblique rods 35. When the anti-collision plate 38 moves backward, the two oblique rods 35 will drive the two sliding blocks 36 to move back to back on the round rod 34. The two sliding blocks 36 are connected by the middle spring 2 314. When moving back to back, the two ends of the spring 2 314 will be pulled to both sides by the two sliding blocks 36. Through elasticity, when the anti-collision plate 38 moves forward, the two sliding blocks 36 move towards each other. The spring 2 314 will also be driven to gather in the middle, so that it bounces back and forth repeatedly at high speed, and with this elastic force, the impact force is slowly absorbed, so that the impact force is gradually released, making the collision process more gentle, reducing the damage and injury caused by the accident, and when the anti-collision plate 38 rebounds after being hit, the anti-collision plate 38 will drive the deceleration block 315 to slide over the side of the resistance block 312. The end of the deceleration block 315 close to the resistance block 312 is provided with an arc surface. The arc surface slope area at the front end of the deceleration block 315 is larger, and the contact area with the resistance block 312 is smaller. When being hit, it can be easily squeezed back and easily slide over the resistance block 312. The arc surface area at the rear end of the deceleration block 315 is smaller, which will increase the contact area with the resistance block 312, so the resistance during rebound will increase, slowing down the speed of the anti-collision plate 38 when rebounding, and reducing the risk of colliding with other vehicles or obstacles again after rebounding.
