[0002] Bridge and tunnel crash bollards are key traffic facilities installed at dangerous locations on roads such as bridges and tunnels. When a collision occurs, the bridge and tunnel crash bollards can absorb the impact energy to play a buffering role, thereby reducing traffic accidents and greatly reducing personal injuries and vehicle damage.
[0003] The more commonly used anti-collision columns on the market now include base cast rigid anti-collision columns, base anchored plastic anti-collision columns, base anchored rigid anti-collision columns, etc. The above anti-collision columns are mainly rigid anti-collision columns, which have the following main defects when used:
[0004] 1. Since the main structure is mainly made of rigid materials, it is easy to be damaged when subjected to external impact force, and the frequency of damage is high, and the repairability is poor;
[0005] 2. The structure is relatively simple and has high rigidity. It cannot effectively buffer the impact force after being hit by an external impact, and is prone to rigid damage. At the same time, since it is mainly connected by rigid connectors, it is easy to cause the impact force to be concentrated at a certain point on the anti-collision plate after being hit, which in turn causes damage to the anti-collision plate, thereby reducing the anti-collision effect of the anti-collision column.
[0006] Based on this, the utility model proposes a bridge and tunnel anti-collision column to solve the problems existing in the above-mentioned prior art. Utility Model Content
[0007] In view of this, the main purpose of the utility model is to provide a bridge and tunnel anti-collision column to solve the problems of poor repairability, inability to effectively buffer impact force and easy damage of traditional bridge and tunnel anti-collision columns.

[0043] As shown in the specification Figures 1-6 drawing, the present utility model provides a technical solution:
[0044] A bridge-tunnel anti-collision column, comprising: an anti-collision column main body 1 and a buffer mechanism 2 provided on the outer surface of the anti-collision column main body 1; wherein:
[0045] The anti-collision column body 1 is a cylindrical structure and is installed at dangerous positions on roads such as bridges and tunnels by expansion bolts during use;
[0046] The buffer mechanism 2 is arranged on the outer surface of the anti-collision column body 1 and includes a circular ring 21 and anti-collision plates 24 symmetrically arranged on the outside of the anti-collision column body 1. The circular ring 21 is detachably installed on the outside of the anti-collision column body 1, and a buffer cylinder 22 and a cancellation cylinder 25 are fixedly connected to the surface of the circular ring 21. Hydraulic oil is filled in the inner cavities of both the buffer cylinder 22 and the cancellation cylinder 25, and a buffer rod 23 is slidably connected to the inner wall of the buffer cylinder 22. The end of the buffer rod 23 is fixed to the surface of the anti-collision plate 24. One end of the buffer cylinder 22 is also communicated with a through pipe 216, and the other end of the through pipe 216 is connected to one end of the cancellation cylinder 25, that is, the buffer cylinder 22 and the cancellation cylinder 25 are communicated through the through pipe 216. A cancellation rod 27 is also slidably connected to the inner cavity of the cancellation cylinder 25; several rubber rollers 26 are rotatably connected to the surface of the anti-collision plate 24 to disperse the impact force through the rubber rollers 26; the surface of the anti-collision plate 24 is bent into an arc shape, and several eye-catching rings 217 for prompting are fixedly connected to the surface of the rubber rollers 26.
[0047] It should be noted that in this embodiment, during the installation process, the anti-collision column body 1 is installed at dangerous positions on roads such as bridges and tunnels by expansion bolts; both the buffer rod 23 and the cancellation rod 27 are rubber components, and one end of the surface of the buffer rod 23 is closely attached to the inner wall of the buffer cylinder 22, and one end of the surface of the cancellation rod 27 is closely attached to the inner wall of the cancellation cylinder 25.
[0048] Specifically: When a vehicle hits the anti-collision plate 24, the rubber rollers 26 rotate to disperse part of the impact force on the anti-collision plate 24. The anti-collision plate 24 with an arc-shaped surface disperses the received impact force. At this time, the movement of the anti-collision plate 24 drives the buffer rod 23 to move inward, so that the buffer rod 23 moves in the buffer cylinder 22, pushing the hydraulic oil to be transported into the cancellation cylinder 25 through the through pipe 216. Excessive hydraulic oil in the cancellation cylinder 25 pushes the cancellation rod 27 to move outward, so that the cancellation rod 27 moves to contact the anti-collision plate 24, thereby buffering and absorbing the energy of the impact force received by the anti-collision plate 24 to reduce the impact force and avoid structural damage to the anti-collision column body 1.
[0049] In a preferred embodiment, as Figure 6As shown, a first spring 28 is also fixedly connected to the end of the buffer rod 23, and the other end of the first spring 28 is fixedly connected to the inner wall of the buffer cylinder 22; and a second spring 215 is fixedly connected to the end of the cancellation rod 27, and the other end of the second spring 215 is fixedly connected to the inner wall of the cancellation cylinder 25; an annularly distributed elastic sleeve 29 is fixedly connected to the surface of the ring 21, and the other end of the elastic sleeve 29 is fixedly connected to the surface of the anti-collision plate 24, and the elastic sleeve 29 is a rubber member.
[0050] It should be noted that in this embodiment, through the settings of the above-mentioned first spring 28, second spring 215 and elastic sleeve 29, the functions of energy absorption and buffering can be achieved; through the setting of the elastic sleeve 29, the buffer cylinder 22 and the cancellation cylinder 25 can also be protected to prevent dust from entering the buffer cylinder 22 and the cancellation cylinder 25, ensuring the use effect.
[0051] In a preferred embodiment, as Figure 5 and Figure 6 shown, a slider 212 is fixedly connected to the lower end of the surface of the ring 21, a fixed block 211 is provided on the surface of the slider 212, a pin rod 213 is slidably connected to the inner wall of the fixed block 211, the surface of the pin rod 213 is clamped to the inner wall of the anti-collision column body 1, and annularly distributed balls 210 are rotatably connected to the surface of the ring 21, and the surface of the balls 210 is rotatably connected to the surface of the anti-collision column body 1. A number of reserved holes are also formed on the surface of the anti-collision column body 1, and the surface of the pin rod 213 is clamped to the inner wall of the reserved holes.
[0052] It should be noted that in this embodiment, when it is necessary to adjust the orientation of the anti-collision plate 24, rotate the anti-collision plate 24 to move to a suitable position annularly on the anti-collision column body 1 so that the anti-collision plate 24 is in the same direction as the driving direction of the road vehicle, and then place the fixed block 211 on the anti-collision column body 1 and move the pin rod 213 in the fixed block 211 to be clamped into the corresponding reserved hole, so that the fixed block 211 is positioned on the anti-collision column body 1, thereby restricting the annular movement range of the ring 21.
[0053] When the anti-collision plate 24 is subjected to an impact force, the anti-collision plate 24 drives the ring 21 to perform a small-amplitude annular movement through the buffer cylinder 22 and the buffer rod 23. The annular movement of the ring 21 drives the slider 212 to perform a small-amplitude annular movement at the fixed block 211 and drives the balls 210 to roll on the anti-collision column body 1, so that the impact force is evenly dispersed at the anti-collision plate 24, avoiding the impact force concentrating at a certain place on the anti-collision plate 24.
[0054] As Figure 6 shown, limit rings 214 are fixedly connected to the inner walls of the buffer cylinder 22 and the cancellation cylinder 25, and the buffer rod 23 and the cancellation rod 27 are limited by the limit rings 214.
[0055] When the bridge-tunnel anti-collision column of the present utility model is in use: the rubber roller 26 rotates to disperse part of the impact force on the anti-collision plate 24, and the anti-collision plate 24 with an arc-shaped surface disperses the received impact force. At this time, the movement of the anti-collision plate 24 drives the buffer rod 23 to move inward, causing the buffer rod 23 to move in the buffer cylinder 22 and push the hydraulic oil through the connecting pipe 216 to the counteracting cylinder 25, stretching the first spring 28. Excessive hydraulic oil in the counteracting cylinder 25 pushes the counteracting rod to move outward, squeezing the second spring 215, causing the counteracting rod 27 to move into contact with the anti-collision plate 24, thereby dispersing the impact force received by the anti-collision plate 24. The anti-collision plate 24 drives the ring 21 and the slider 212 to perform a small-amplitude circular movement at the fixed block 211 through the buffer cylinder 22 and the buffer rod 23, and drives the ball 210 to roll on the anti-collision column main body 1, so that the impact force is evenly dispersed at the anti-collision plate 24, avoiding the concentration of the impact force at a certain point of the anti-collision plate 24, thus ensuring good buffering and anti-collision effects; it solves the problems of poor repairability, inability to effectively buffer the impact force and easy damage existing in the traditional bridge-tunnel anti-collision column.
[0056] It should be noted that the anti-collision column main body 1, the first spring 28, the second spring 215, etc. in the above description are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs and will not be elaborated here.
[0057] The above is only a preferred embodiment of the present utility model and is not intended to limit the protection scope of the present utility model.
