Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision guardrails, in particular to an anti-collision guardrail for road and bridge. Background Art

[0002] The anti-collision guardrail for road and bridge is a protective facility installed at the edge of a bridge, aiming to prevent vehicles from colliding with the bridge or falling into rivers and other dangerous situations. It has characteristics such as elasticity, visibility, durability and mobility, and can provide safety protection, guidance and reminder functions, reduce the accident rate, mitigate the consequences of accidents, and maintain traffic order.

[0003] However, some anti-collision guardrails are made of metal materials, and there is a lack of a buffer mechanism between the anti-collision railing and the mounting frame, resulting in a relatively single anti-collision function of the anti-collision guardrail. When a vehicle collides with the anti-collision guardrail, if the anti-collision railing is deformed, the protection ability of the anti-collision guardrail will rapidly decline, and thus it cannot effectively absorb the impact force generated by the vehicle, increasing the probability of injury to the personnel in the vehicle.

[0004] Therefore, there is an urgent need to redesign a new anti-collision guardrail for road and bridge to solve the above problems. Summary of the Utility Model

[0005] The utility model provides an anti-collision guardrail for road and bridge to solve the technical problems put forward in the above background art.

[0006] The utility model provides an anti-collision guardrail for road and bridge, which includes several anti-collision railings and at least a pair of support assemblies;

[0007] Each pair of support assemblies is respectively arranged on both sides of the anti-collision railing. The support assembly includes a base, a pair of columns are fixedly connected to the base, a reinforcing member is fixedly connected between the pair of columns, several protrusions are connected to the columns, the protrusions correspond to the anti-collision railing, and a buffer mechanism is installed in the protrusions.

[0008] Optionally, a buffer cavity is provided in the column and the protrusion and is mutually communicated. The buffer cavity is used to accommodate the arc-shaped plate and at the same time reserve space for the movement of the arc-shaped plate. One end of the anti-collision railing is arranged in the buffer cavity.

[0009] Optionally, the buffer mechanism includes an arc-shaped plate. The arc-shaped plate is arranged in the buffer cavity and is in contact with the anti-collision railing. When the anti-collision railing is impacted by a vehicle, the anti-collision railing has a force on the arc-shaped plate, so that the arc-shaped plate moves in the buffer cavity to buffer the impact force received by the anti-collision railing and improve the overall anti-collision ability of the anti-collision railing;

[0010] A linkage rod is fixedly connected to the arc-shaped plate. The linkage rod is used to connect the arc-shaped plate and the extrusion plate, so as to realize the linkage between the arc-shaped plate and the extrusion plate.

[0011] Optionally, a spring is provided in the buffer cavity. The spring is arranged outside the linkage rod and between the arc-shaped plate and the inner wall of the buffer cavity. The spring is used to apply an elastic force to the arc-shaped plate, thereby increasing the resistance of the arc-shaped plate to move in the buffer cavity, buffering the impact force received by the anti-collision railing, and improving the anti-collision ability of the anti-collision railing.

[0012] Optionally, a cavity is provided in the protrusion. The cavity corresponds to the buffer cavity and is used to accommodate the extrusion plate and the buffer liquid.

[0013] Optionally, an extrusion plate is provided in the cavity. One end of the linkage rod is fixedly connected to the extrusion plate. The extrusion plate is used to extrude the buffer liquid, achieving the purpose of further buffering.

[0014] A receiving cavity and a release cavity are formed between the extrusion plate and the inner wall of the cavity.

[0015] Optionally, the receiving cavity is provided with buffer liquid. When the arc-shaped plate moves in the buffer cavity, the extrusion plate will also move in the cavity through the linkage rod. When the extrusion plate moves, it will extrude the buffer liquid, thereby using the buffer liquid to play a role of buffering again and further increasing the anti-collision ability of the anti-collision railing.

[0016] Optionally, a number of horn-shaped holes are provided on the extrusion plate. The horn-shaped holes are used to release the buffer liquid, using the release of the buffer liquid to play a role of unloading force, thereby achieving a buffering effect.

[0017] A wire mesh is installed at the maximum diameter of the horn-shaped hole. The wire mesh is used to limit the blocking ball. The blocking ball is clamped at the minimum diameter of the horn-shaped hole. The blocking ball is used to block the horn-shaped hole, making it difficult for the buffer liquid to enter the release cavity through the horn-shaped hole in the natural state.

[0018] Optionally, an elastic cord is connected between the wire mesh and the blocking ball. The elastic cord is used to install a rubber sleeve. A rubber sleeve is provided on the outer side of the elastic cord. The rubber sleeve is used to apply a force to the blocking ball, making the blocking ball clamped at the minimum diameter of the horn-shaped hole in the natural state for blocking the horn-shaped hole.

[0019] Optionally, a pipe sleeve is provided in the buffer cavity. One end of the anti-collision railing passes through the pipe sleeve and is arranged in the buffer cavity. The pipe sleeve is used to position the anti-collision railing and is also used to connect the shielding curtain.

[0020] A shielding curtain is connected to the pipe sleeve. The shielding curtain covers the port of the buffer cavity. The shielding curtain can block the buffer cavity, making it difficult for the arc-shaped plate and the spring to be affected by the external environment.

[0021] The beneficial effects of the present utility model are as follows:

[0022] Through the setting of corresponding mechanisms, the anti-collision ability of the anti-collision railing for road bridges can be increased, and at the same time, the impact force generated by the vehicle can be effectively absorbed, and to a certain extent, the injury to the personnel in the vehicle can be reduced.

[0030] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present invention. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0031] Please refer to Figures 1 to 5 , a road and bridge anti-collision guardrail of the present invention includes a plurality of anti-collision railings 1 and at least a pair of support assemblies 2.

[0032] Please refer toFigures 1 to 5 , each pair of support assemblies 2 are respectively arranged on both sides of the anti-collision railing 1, and the support assembly 2 is used to install a plurality of anti-collision railings 1. In this application, three anti-collision railings 1 are installed between a pair of support assemblies 2.

[0033] Among them, the support assembly 2 includes a base 201, and the base 201 is fixedly connected to the ground by bolts. A pair of columns 202 are fixedly connected to the base 201. The columns 202 are used to install the anti-collision railing 1. A reinforcing member 203 is fixedly connected between the pair of columns 202. Through the arrangement of the reinforcing member 203, the connection strength between the pair of columns 202 can be increased, and the overall anti-collision ability can be ensured.

[0034] In addition, a plurality of protrusions 204 are connected to the column 202. The protrusions 204 correspond to the anti-collision railing 1, and the protrusions 204 are used to install a buffer mechanism.

[0035] Preferably, the protrusions 204 are arranged on the side away from the road surface, that is, the protrusions 204 are arranged on the back side of the road surface, so that it is not easy for the vehicle to collide with the protrusions 204.

[0036] Specifically, a buffer cavity 205 that communicates with each other is provided in the column 202 and the protrusion 204. The buffer cavity 205 is used to accommodate the arc-shaped plate 206 and at the same time reserve space for the movement of the arc-shaped plate 206. One end of the anti-collision railing 1 is arranged in the buffer cavity 205.

[0037] Please refer to Figures 1 to 5 , a buffer mechanism is installed in the protrusion 204. By using the buffer mechanism, the overall anti-collision ability can be increased, the impact force generated by the vehicle on the anti-collision railing 1 can be effectively absorbed, and to a certain extent, the injury suffered by the personnel in the vehicle can be reduced.

[0038] Among them, the buffer mechanism includes an arc-shaped plate 206. The arc-shaped plate 206 is arranged in the buffer cavity 205, and the arc-shaped plate 206 is in contact with the anti-collision railing 1. When the anti-collision railing 1 is collided by the vehicle, the anti-collision railing 1 has a force on the arc-shaped plate 206, and then the arc-shaped plate 206 moves in the buffer cavity 205 to buffer the impact force received by the anti-collision railing 1 and improve the overall anti-collision ability of the anti-collision railing 1.

[0039] In addition, a linkage rod 207 is fixedly connected to the arc-shaped plate 206. The linkage rod 207 is used to connect the arc-shaped plate 206 and the extrusion plate 210, and thus the linkage between the arc-shaped plate 206 and the extrusion plate 210 can be realized.

[0040] Specifically, a spring 208 is provided in the buffer cavity 205. The spring 208 is disposed outside the linkage rod 207 and between the arc-shaped plate 206 and the inner wall of the buffer cavity 205. The spring 208 is used to apply an elastic force to the arc-shaped plate 206, thereby increasing the resistance of the arc-shaped plate 206 to move in the buffer cavity 205, buffering the impact force received by the anti-collision railing 1, and improving the anti-collision ability of the anti-collision railing 1.

[0041] Please refer to Figures 1 to 5 , a cavity 209 is provided in the protrusion 204. The cavity 209 corresponds to the buffer cavity 205 and is used to accommodate the extrusion plate 210 and the buffer liquid 211.

[0042] Among them, an extrusion plate 210 is provided in the cavity 209, and one end of the linkage rod 207 is fixedly connected to the extrusion plate 210. The extrusion plate 210 is used to extrude the buffer liquid 211, which can achieve the purpose of further buffering.

[0043] In addition, a plurality of horn-shaped holes 2101 are provided on the extrusion plate 210. The horn-shaped holes 2101 are used to release the buffer liquid 211, and the release of the buffer liquid 211 is used to play a role in unloading force, thereby achieving a buffering effect.

[0044] Specifically, a wire mesh 2102 is installed at the maximum diameter of the horn-shaped hole 2101. The wire mesh 2102 is used to limit the blocking ball 2103. A blocking ball 2103 is engaged at the minimum diameter of the horn-shaped hole 2101. The blocking ball 2103 is used to block the horn-shaped hole 2101, so that the buffer liquid 211 is not easily passed through the horn-shaped hole 2101 into the release cavity in the natural state.

[0045] In addition, an elastic rope 2104 is connected between the wire mesh 2102 and the blocking ball 2103. The elastic rope 2104 is used to install a rubber sleeve 2105. A rubber sleeve 2105 is provided outside the elastic rope 2104. The rubber sleeve 2105 is used to apply a force to the blocking ball 2103, so that the blocking ball 2103 is engaged at the minimum diameter of the horn-shaped hole 2101 in the natural state, and is used to block the horn-shaped hole 2101.

[0046] Please refer to Figures 1 to 5 , a receiving cavity and a release cavity are formed between the extrusion plate 210 and the inner wall of the cavity 209.

[0047] Among them, the receiving cavity is provided with the buffer liquid 211. When the arc-shaped plate 206 moves in the buffer cavity 205, the extrusion plate 210 will also move in the cavity 209 through the linkage rod 207. When the extrusion plate 210 moves, it will extrude the buffer liquid 211, thereby using the buffer liquid 211 to play a role of re-buffering and further increasing the anti-collision ability of the anti-collision railing 1.

[0048] Preferably, the buffer liquid 211 is water.

[0049] In addition, a pipe sleeve 212 is provided in the buffer cavity 205. One end of the anti-collision railing 1 passes through the pipe sleeve 212 and is arranged in the buffer cavity 205. The pipe sleeve 212 is used to position the anti-collision railing 1 and is also used to connect the shielding curtain 213.

[0050] Specifically, a shielding curtain 213 is connected to the pipe sleeve 212. The shielding curtain 213 covers the port of the buffer cavity 205. The shielding curtain 213 can block the buffer cavity 205, so that the arc-shaped plate 206 and the spring 208 are not easily affected by the external environment.

[0051] Preferably, the shielding curtain 213 is made of rubber material, so that the shielding curtain 213 has elasticity and can also ensure the service life of the shielding curtain 213.

[0052] In addition, a supplementary pipe and a drain pipe are also provided on the protrusion 204. The supplementary pipe is communicated with the accommodation cavity, and the drain pipe is communicated with the release cavity. When the vehicle collides with the anti-collision railing 1, the buffer liquid 211 will enter the release cavity through the horn hole 2101 under the extrusion of the extrusion plate 210, and the buffer liquid 211 in the release cavity can be discharged through the drain pipe. If the support assembly 2 is not damaged during the vehicle collision, the staff can replenish the buffer liquid 211 into the accommodation cavity through the supplementary pipe to reuse it.

[0053] During specific use, when the vehicle collides with the anti-collision railing 1, the anti-collision railing 1 will be subjected to the impact force of the vehicle. The anti-collision railing 1 has a force on the arc-shaped plate 206, so that the arc-shaped plate 206 moves in the buffer cavity 205. The spring 208 in the buffer cavity 205 has an elastic force on the arc-shaped plate 206, which can increase the resistance of the arc-shaped plate 206 moving in the buffer cavity 205, so as to buffer the impact force received by the anti-collision railing 1 and improve the anti-collision ability of the anti-collision railing 1.

[0054] At the same time, the linkage rod 207 drives the extrusion plate 210 to move in the cavity 209 and extrudes the buffer liquid 211 in the accommodation cavity. As the extrusion plate 210 moves, the space of the accommodation cavity gradually becomes smaller until the buffer liquid 211 fills the accommodation cavity. At this time, the buffer liquid 211 has an extrusion force on the plugging ball 2103.

[0055] When the extrusion force of the buffer liquid 211 on the plugging ball 2103 is greater than the acting force of the rubber sleeve 2105 on the plugging ball 2103, the plugging ball 2103 is extruded and loosened and disengages from the engagement with the minimum diameter of the horn hole 2101. At this time, the buffer liquid 211 can enter the release cavity through the horn hole 2101, and the flow of the buffer liquid 211 can play a role in buffering the impact force received by the anti-collision railing 1 again.

[0056] Through the movement of the anti-collision railing 1, the elastic force of the spring 208 on the arc-shaped plate 206, and the flow of the buffer liquid 211, the anti-collision ability of the overall anti-collision railing 1 can be increased, and the impact force generated by the vehicle can be effectively absorbed, and to a certain extent, the harm suffered by the personnel in the vehicle can be reduced.

[0057] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
