Description

Technical Field

[0001] This invention relates to the field of road traffic safety, and specifically to a road traffic safety barrier. Background Technology

[0002] Traffic guardrails are safety protection structures that can absorb collision energy through self-deformation or vehicle climbing. They can prevent vehicles from changing their direction of travel and prevent vehicles from going off the road or entering the oncoming lane when a traffic accident occurs, thereby minimizing injury to occupants.

[0003] When a vehicle collides with a guardrail, the lifting system inside a traditional retractable guardrail will be damaged by the impact force, thus obstructing traffic. In order to allow vehicles to pass quickly, the motor inside a typical retractable guardrail is always in a connected state. When a vehicle collides with the guardrail, the motor torque inside the guardrail will be subjected to a large torque force under the impact force, which will damage the motor output shaft and increase maintenance costs.

[0004] Therefore, it is necessary to invent a road traffic safety barrier. Summary of the Invention

When the guardrail serves its protective function, i.e., it blocks vehicles, the servo motor and transmission component are in a separated state. At this time, when a vehicle collides with the guardrail, the impact force on the vehicle can be effectively reduced. Simultaneously, the movable connection between the load-bearing plate and the drive plate can effectively reduce the impact of the vehicle impact force on the internal lifting system of the guardrail, thereby solving the problems of existing traffic guardrails being easily damaged and having high maintenance costs.

[0017] The beneficial effects of this invention are:

[0018] 1. When a traffic accident occurs, the vehicle hits the impact plate, causing the impact plate to compress the buffer plate. Under the elastic force of the first spring column, the impact force of the vehicle will be greatly reduced. Similarly, when the buffer plate is under force, it will move inward, thereby squeezing the thrust seat inward through two sets of connecting rods. Under the action of the second set of spring columns, the impact force is further reduced. The reduced impact force is transmitted to the drive plate through the crossbar. Since the drive plate is movably connected to the load-bearing plate, when the impact force is transmitted to the drive plate, it can be completely absorbed by the drive plate, so as not to affect the operation of the subsequent device. At the same time, the telescopic spring on the load-bearing plate can also effectively alleviate the impact force. At this time, since the servo motor and the transmission components are in an open circuit state, the servo motor can be effectively protected from impact damage.

[0019] 2. When the "lifting bar" operation is required, simply drive cylinder two to make its output shaft rotate one end of the lever. Under the action of the rotating column, the other end of the lever moves the limit card forward. At this time, the output shaft of the servo motor drives the rotating shaft to rotate, so that the limit bar one engages with the limit hole, causing gear two to rotate. Since gear two meshes with the internal gear ring, the internal gear ring rotates synchronously. With the movement of the output shaft of cylinder two, the limit card drives the push ring and the internal gear ring to move forward synchronously. When the internal gear ring meshes with the gear ring, it can drive the transmission column to rotate synchronously, thereby driving the coupling at the rear end of the transmission column to rotate, causing the transmission component connected to the coupling to work, so that the crossbar is lifted, completing the lifting bar action. Since the servo motor and the transmission component are always separated, it can effectively ensure that the servo motor is not affected by the impact force when the crossbar is hit.

The right side of the load-bearing plate 130 is inserted into the inner wall of the movable groove 122. The plug ring 123 is inserted into the inner wall of the sliding groove 131 and is movably connected to the load-bearing plate 130. The right side of the telescopic spring 132 is fixedly connected to the inner wall of the movable groove 122.

[0039] The transmission assembly 140 includes an elliptical plate 141, which is fixedly installed on the left side of the load-bearing plate 130. An elastic belt transmission mechanism 143 is provided on the left side of the elliptical plate 141. A retaining column 146 is fixedly installed on the right side of the top pulley of the elastic belt transmission mechanism 143. A gear 147 is fixedly installed on the right side of the retaining column 146. The retaining column 146 is inserted into the inner wall of the top of the elliptical plate 141.

A hexagonal prism 149 is fixedly installed on the left side of the bottom pulley of the elastic belt transmission mechanism 143. Specifically, when the hexagonal prism 149 meshes with the hexagonal hole 183, the coupling 182 drives the elastic belt transmission mechanism 143 to rotate, thereby causing the top pulley of the elastic belt transmission mechanism 143 to drive the retaining column 146 to rotate synchronously, so that the gear 147 at the front end of the retaining column 146 meshes with the teeth 124, thereby causing the drive plate 121 to rotate, which in turn drives the crossbar 210 to rotate.

The base 247 slides through the bottom of the base column 231 and is slidably connected to the strip groove 233. The bottom of another set of spring columns 246 is fixedly connected to the top of the base 247. Specifically, when a traffic accident occurs, the vehicle hits the impact plate 241, causing the impact plate 241 to be compressed against the buffer plate 243. Under the elastic force of the spring column 242, the impact force of the vehicle will be greatly reduced. Similarly, when the buffer plate 243 is subjected to force, it will move inward, thereby squeezing the thrust seat 245 inward through the two sets of connecting rods 244. Under the action of the two sets of spring columns 246, the impact force is further reduced.

[0042] Furthermore, a support plate 110 is fixedly installed on one side of the box body 101, and the bottom left side of the crossbar 210 is installed on the inner wall of the support plate 110.

[0043] Furthermore, a bearing 148 is fixedly installed on the inner wall of the top of the elliptical plate 141. The bearing 148 is movably connected to the retaining column 146 and provides support for the retaining column 146. A flat bearing 142 is installed on the bottom left side of the elliptical plate 141 and provides support for the bottom pulley of the elastic belt drive mechanism 143. The flat bearing 142 is movably connected to the bottom pulley of the elastic belt drive mechanism 143. A movable groove 144 is provided on the left side of the top pulley of the elastic belt drive mechanism 143. A support column 145 is provided on the left side of the elastic belt drive mechanism 143. The support column 145 is inserted into the movable groove 144 and is movably connected to the elastic belt drive mechanism 143. The left side of the support column 145 is fixedly connected to the inner wall of the housing 101 and provides support for the top pulley of the elastic belt drive mechanism 143.

[0044] Furthermore, a cylinder 150 is fixedly installed at the center of the left side of the elliptical plate 141. A rotating ring 151 is installed at the output end of the cylinder 150. The rotating ring 151 contacts the belt of the elastic belt drive mechanism 143. The output shaft of the cylinder 150 can drive the rotating ring 151 to move outward, thereby causing the rotating ring 151 to squeeze the drive belt of the elastic belt drive mechanism 143 and make it taut.

[0045] Furthermore, a base plate 160 is fixedly installed on the inner wall of the housing 101, and a servo motor 164 is fixedly installed on the top of the base plate 160. The protective component 170 includes a gear 171, with a limit hole 172 on the inner wall of the gear 171. A rotating shaft 173 is fixedly installed at the output end of the servo motor 164. Limiting strips 174 are evenly installed on the left side of the outer wall of the rotating shaft 173, and limiting strips 175 are evenly installed on the right side of the outer wall of the rotating shaft 173. The rotating shaft 173 is inserted into the inner wall of the gear 171, and the limiting strips 174 mesh with the limiting hole 172. A transmission column 176 is provided on the right side of the gear 171, and a coupling 182 is fixedly installed on the right side of the transmission column 176. A hexagonal hole 183 is opened on the right side of the coupling 182, and a hexagonal prism 149 is inserted into the inner wall of the hexagonal hole 183. A gear ring 177 is fixedly installed on the left outer wall of the transmission column 176, and a bearing 175 is fixedly installed on the right inner wall of the transmission column 176. 178.

The rotating shaft 173 is inserted into the inner wall of the transmission column 176, and the limiting strip 175 meshes with the inner limiting sleeve 179. A convex ring 180 is provided between gear 171 and transmission column 176. A mating gear ring 181 is fixedly installed on the right side of the convex ring 180. A recess 186 is fixedly installed on the inner wall of the right side of gear 171. A boss 187 is fixedly installed on the left side of transmission column 176. The left side of the convex ring 180 contacts the recess 186 and the right side contacts the boss 187. Specifically, the output shaft of servo motor 164 drives the rotating shaft 173 to rotate, so that the limiting strip 174 engages with the limiting hole 172, causing gear 171 to rotate. The recess 186 drives the convex ring 180 to rotate. As the limiting card 190 drives the inner gear ring 189 to move, the engagement between the convex ring 180 and the boss 187 gradually tightens. This causes the rotational speed of the boss 187 to increase slowly. When the internal gear ring 189 meshes with the gear ring 177, the rotational speed of the transmission column 176 and the gear 171 is the same.

[0046] Furthermore, a thrust ring 184 is provided on the outer wall of gear 2 171, convex ring 180, and transmission column 176. Bearing 3 188 is fixedly installed on the inner wall of thrust ring 184, and an internal gear ring 189 is fixedly installed on the inner wall of bearing 3 188. The internal gear ring 189 meshes with gear 2 171. A slot 185 is opened on the outer wall of thrust ring 184, and a limit card 190 is fixedly installed on the outer wall of slot 185. A rotating column 162 is rotatably connected to the top of base plate 160. A lever 163 is fixedly installed on the top of rotating column 162. One end of lever 163 is fixedly connected to limit card 190. A pneumatic cylinder is fixedly installed on the top of base plate 160. Cylinder 161, the output end of cylinder 161 is fixedly connected to the other end of lever 163. Specifically, driving cylinder 161, the output shaft of cylinder 161 drives lever 163 to rotate, thereby causing the other end of lever 163 to drive limit card 190 to move outward, causing the internal gear ring 189 inside the push ring 184 to move outward slowly. When the internal gear ring 189 meshes with gear ring 177, it can drive transmission column 176 to rotate synchronously, thereby driving the coupling 182 at the rear end of transmission column 176 to rotate, causing the transmission component 140 connected to coupling 182 to work.

[0047] The usage process of this invention is as follows: When a traffic accident occurs, the vehicle hits the impact plate 241, causing the impact plate 241 to be compressed against the buffer plate 243. Under the elastic force of the spring column 242, the impact force of the vehicle will be greatly reduced. Similarly, when the buffer plate 243 is subjected to force, it will move inward, thereby pressing the thrust seat 245 inward through the two sets of connecting rods 244. Under the action of the two sets of spring columns 246, the impact force is further reduced. The reduced impact force is transmitted to the drive plate 121 through the crossbar 210. Since the drive plate 121 is movably connected to the load plate 130, when the impact force is transmitted to the drive plate 121, it can be completely absorbed by the drive plate 121, so as not to affect the operation of the subsequent device. At the same time, the telescopic spring 132 on the load plate 130 can also effectively alleviate the impact force. At this time, since the servo motor 164 and the transmission component 140 are in an open circuit state, the servo motor 164 can be effectively protected from impact damage.

[0048] When a "lever lifting" operation is required, simply drive cylinder 161 to rotate one end of lever 163 via its output shaft. Under the action of rotating column 162, the other end of lever 163 moves the limit stop 190 forward. At this time, the output shaft of servo motor 164 drives rotating shaft 173 to rotate, causing limit bar 174 to engage with limit hole 172, causing gear 171 to rotate. Since gear 171 meshes with internal gear ring 189, internal gear ring 189 rotates synchronously. With the movement of cylinder 161's output shaft, limit stop 190 drives the push ring 184 and internal gear ring 189 to move forward synchronously. When internal gear ring 189 meshes with gear ring 177, it can drive the transmission... The moving column 176 rotates synchronously, thereby driving the coupling 182 at the rear end of the transmission column 176 to rotate. When the hexagonal prism 149 meshes with the hexagonal hole 183, the coupling 182 drives the elastic belt transmission mechanism 143 to rotate, thereby causing its top pulley to drive the locking column 146 to rotate synchronously, causing the gear 147 at the front end of the locking column 146 to mesh with the tooth 124, thereby causing the drive disk 121 to rotate, driving the horizontal bar 210 to rotate, so that the horizontal bar 210 is lifted, completing the lifting action. Since the servo motor 164 and the transmission assembly 140 are always separated, it can be effectively ensured that when the horizontal bar 210 is impacted, the servo motor 164 will not be affected by the impact force.
