Description

Technical Field

[0001] The utility model relates to the technical field of road equipment, in particular to a roadway barrier. Background Art

[0002] The lane gate, also known as the vehicle blocker, is a channel entrance and exit management device specially used to restrict the travel of motor vehicles on the road. It is now widely used in highway toll stations and parking systems to manage vehicle channels and to manage the entry and exit of vehicles. The lane gate is generally electric, and the barrier can be raised and lowered by wireless remote control. It can also be automatically managed through the parking management system (i.e. IC card swiping management system). Vehicles are released by taking the card when entering the parking lot, and automatically released after collecting the parking fee when leaving the parking lot.

[0003] The existing barriers generally include a base and a guardrail rotatably mounted on the base. An asynchronous AC motor is connected to the guardrail through a reduction gearbox to drive the guardrail to rotate. Since the transmission between the guardrail and the motor is generally connected through a reduction gearbox, the transmission connection method is a rigid connection. When the guardrail is hit, a rigid collision will occur. For the coordination of the vehicle and the gear of the reduction gearbox, the rigid collision has a huge impact and seriously affects safety. At the same time, even a slight impact on the existing barriers will cause the guardrail of the barriers to fail to rise and fall normally, and the service life is short. Utility Model Content

[0041] The guardrail or railing of the existing lane gate refers to the rod component used to intercept vehicles. The guardrail is mainly an integrally formed long strip plate with high rigidity. The guardrail is rigidly connected to the driver on the base through a reducer. When the guardrail is hit, a rigid collision will occur, causing great damage to the driver and the vehicle. Even if the guardrail is slightly hit, it will cause the guardrail to be unable to rise and fall, and the service life of the lane gate will be short. At the same time, the rigid collision will cause great damage to the reducer and the driver, especially it will seriously affect the meshing accuracy of the gears of the reducer, causing jamming and noise when the guardrail is raised and lowered. In addition, when a vehicle has an accident and hits the guardrail, causing the guardrail to be unable to rise and fall, it will reduce the speed of accident handling, resulting in the road being unable to be cleared quickly, and the road being unable to be restored to smooth flow in a short time, causing traffic jams.

[0042] like Figures 1 to 5 As shown, this embodiment provides a lane barrier, including a base 11, a guardrail 12, and a driver. The guardrail 12 can be raised and lowered around the base 11 to switch between a lowered state and a retracted state. The driver is used to drive the guardrail 12 to rotate.

[0043] The railing 12 includes a movable seat 121, a first hinge 122, a first torsion spring 123, and a connecting seat 124 rotatably mounted on the base 11. The driver is in transmission connection with the connecting seat 124 to drive the connecting seat 124 to rotate around the base 11. There are a plurality of movable seats 121, a plurality of first hinges 122, and a plurality of first torsion springs 123, respectively, and the plurality of first hinges 122 and the plurality of first torsion springs 123 correspond to each other one by one, and the first torsion spring 123 is mounted on the first hinge 122.

[0044] The plurality of movable seats 121 are sequentially connected by first hinges 122 and sequentially distributed along a predetermined path. Any two adjacent movable seats 121 are connected by a first hinge 122. The first hinge 122 allows the adjacent movable seats 121 to rotate relative to each other. When the guardrail 12 is lowered to a horizontal state, the adjacent movable seats 121 can rotate relative to each other horizontally. The movable seat 121 located at one end of the predetermined path is connected to the connecting seat 124. For example, when the base 11 is located on the left side of the guardrail 12, the movable seat 121 located at the leftmost side and close to the connecting seat 124 or the base 11 among the plurality of connecting seats 124 is connected to the connecting seat 124. When the movable seat 121 is connected to the connecting seat 124, it can be fixedly connected or hinged to each other by a second hinge. When connected by a second hinge, a second torsion spring is installed on the second hinge, one torsion axis of the second torsion spring is connected to the connecting seat 124, and the other torsion axis of the second torsion spring is connected to the movable seat 121. The two torsion axes of each first torsion spring 123 are respectively connected to two adjacent movable seats 121. The first torsion spring 123 makes the adjacent movable seats 121 tend to remain on the same straight line. The adjacent movable seats 121 are connected by the first torsion spring 123. The first torsion spring 123 applies elastic force to the adjacent movable seats 121 so that all the movable seats 121 are located on the same straight line. At this time, the predetermined path is a horizontal straight path. When the railing 12 is impacted, the torsion spring is twisted, and the movable seat 121 can rotate back and forth.

[0045] In this way, under the action of the first torsion spring 123, the connecting seat 124 and each movable seat 121 are located on the same straight line, and the driver can rotate the barrier 12 up and down to realize the lifting and lowering of the barrier 12. When the driver drives the barrier 12 to rotate upward and leave the lane, the vehicle is allowed to pass. When the driver drives the barrier 12 to rotate downward, the barrier 12 horizontally spans the lane, and each movable seat 121 is located above the lane to block the vehicle. When the vehicle accidentally hits the barrier 12 due to improper operation or failure, slippage, etc., the vehicle first hits the movable seat 121, and the impacted movable seats 121 can rotate around the first hinge 122, and the barrier 12 rotates and bends forward. In other words, the vehicle moves forward, the barrier 12 is in front of the vehicle, and the barrier 12 is bent along the forward direction of the vehicle under the action of the vehicle, avoiding the rigid collision between the vehicle and the barrier 12, reducing the damage caused by the collision to the vehicle, the driver, and the lane gate, and improving the safety of the lane gate and the service life of the lane gate. When the vehicle that has collided retreats, the guardrail 12 returns to a horizontal state under the action of the first torsion spring 123, which does not affect normal use. The guardrail 12 can also be raised or lowered without affecting the smooth flow of the road.

[0046] In one embodiment, the movable seat 121 includes a first rotating block 1211 and a second rotating block 1212. The first rotating block 1211 and the second rotating block 1212 are hinged to each other, and the first rotating block 1211 and the second rotating block 1212 can rotate up and down relatively. The rotation axis between the first rotating block 1211 and the second rotating block 1212 that are hinged to each other is perpendicular to the rotation axis between two adjacent movable seats 121. When the guardrail 12 is arranged horizontally, the rotation axis between the two movable seats 121 is vertically arranged, and the two movable seats 121 can rotate forward and backward relatively. The rotation axis between the first rotating block 1211 and the second rotating block 1212 is horizontally arranged from front to back, and the first rotating block 1211 and the second rotating block 1212 can rotate up and down relatively. The first rotating block 1211 has a first limiting portion 1217, and the second rotating block 1212 has a second limiting portion 1218. When the guardrail 12 is arranged horizontally, under the action of gravity, the first limiting portion 1217 and the second limiting portion 1218 abut against each other so that the first rotating block 1211 and the second rotating block 1212 in the movable seat 121 are located on the same straight line, limiting the freedom of the first rotating block 1211 and the second rotating block 1212 to rotate relative to each other in the front-back direction, so that the guardrail 12 is in a straight state extending horizontally. When the guardrail 12 is in a straight state, the first limiting portion 1217 and the second limiting portion 1218 abut against each other and can also prevent the guardrail 12 from bending downward. At present, some guardrails 12 do not have the obstacle avoidance function. Some guardrails 12 avoid obstacles by setting sensors to sense whether there are vehicles or pedestrians passing below, but this obstacle avoidance method is prone to errors, resulting in the guardrail 12 hitting the vehicle or pedestrian located directly below. In addition to being able to rotate up and down to reduce the collision stiffness in the horizontal direction, the guardrail 12 of this embodiment can also be rotated up and down to reduce the collision stiffness in the vertical direction. When a vehicle or pedestrian passes by directly below the guardrail 12 and the movable seat 121 of the guardrail 12 hits the vehicle or pedestrian, the second rotating block 1212 can be bent upward relative to the first rotating block 1211 under the action of the vehicle or pedestrian below it, or the first rotating block 1211 can be bent upward relative to the second rotating block 1212 under the action of the vehicle or pedestrian below it, thereby reducing the damage caused by the guardrail 12 to the vehicle and pedestrian.

[0047] Furthermore, the guardrail 12 has a lowered state and a retracted state. When the guardrail 12 is in the lowered state, the connecting seat 124 and the plurality of movable seats 121 are sequentially distributed along a horizontal straight path, the guardrail 12 can be across the road, the rotation axis between two adjacent movable seats 121 is vertically arranged, the rotation axis between the mutually hinged first rotating block 1211 and the second rotating block 1212 is horizontally arranged, the first limiting portion 1217 and the second limiting portion 1218 are both located below the rotation axis between the first rotating block 1211 and the second rotating block 1212, the first limiting portion 1217 and the second limiting portion 1218 abut against each other under the action of gravity and prevent the first rotating block 1211 and the second rotating block 1212 from continuing to rotate downward, so that the guardrail 12 is in a horizontal state. When the railing 12 is in the retracted state, the connecting seat 124 and the multiple movable seats 121 are distributed in sequence along a vertical straight path, and the railing 12 extends upward. Specifically, the railing 12 extends upward at an angle, and the connecting seat 124 is located below the movable seat 121, which can prevent the railing 12 from bending up and down.

[0048] In one embodiment, a pivoting groove 1213 is provided on the first rotating block 1211, a connecting shaft 1214 is provided in the pivoting groove 1213, a pivoting block 1215 is provided on the second rotating block 1212, the pivoting block 1215 and the second rotating block 1212 are integrally formed, an axial hole 1216 is provided on the pivoting block 1215, the pivoting block 1215 is sleeved on the connecting shaft 1214 through the axial hole 1216, and a rounded corner or chamfer is provided on the edge above the pivoting groove 1213 to facilitate the second rotating block 1212 to rotate around the first rotating block 1211. In this way, when the movable seat 121 hits a vehicle or a pedestrian downward, the second rotating block 1212 can rotate upward around the first rotating block 1211 to achieve the upward bending of the guardrail 12, thereby preventing the guardrail 12 from being directly pressed on the vehicle or pedestrian under the full action.

[0049] Furthermore, soft cushions may be provided below the connecting seat 124 and the movable seat 121 to reduce the damage to vehicles or pedestrians caused when the guardrail 12 rotates downward and hits the vehicles or pedestrians.

[0050] In one embodiment, the first hinge 122 includes a first connecting plate 1221, a second connecting plate 1222, and a first pivot 1223. The first connecting plate 1221 is rotatably connected to the second connecting plate 1222 via the first pivot 1223, the first torsion spring 123 is sleeved on the first pivot 1223, the first connecting plate 1221 is mounted on one of the movable seats 121, and the second connecting plate 1222 is mounted on another adjacent movable seat 121.

[0051] Optionally, the movable seat 121 has a rear side and a front side, the rear side is the side close to the vehicle, and the front side is the side away from the vehicle, and the first connecting plate 1221 and the second connecting plate 1222 are respectively connected to the front sides of adjacent movable seats 121.

[0052] It is understandable that the second hinge includes a third connecting plate, a fourth connecting plate, and a second pivot. The second hinge has the same structure as the first hinge 122, and will not be described in detail herein.

[0053] Optionally, a first plate groove 125 is formed at one end of the movable seat 121, and a second plate groove 126 is formed at the other end of the movable seat 121. The first connecting plate 1221 is clamped in the first plate groove 125 of one of the movable seats 121 and connected to the inner wall of the first plate groove 125 through a threaded fastener, and the second connecting plate 1222 is clamped in the second plate groove 126 of another adjacent movable seat 121 and connected to the inner wall of the second plate groove 126 through a threaded fastener. In this way, after the first hinge 122 is installed on the movable seat 121, the first connecting plate 1221 is flush with the outer side surface of the movable seat 121, and the second connecting plate 1222 is flush with the outer side surface of the movable seat 121.

[0054] In one embodiment, an anti-rust layer is sprayed on the first hinge 122 and the first torsion spring 123 to prevent rust. Reflective strips 13 are laid on the connecting seat 124 and each movable seat 121 to serve as a warning.

[0055] Furthermore, the first hinge 122 and the first torsion spring 123 are covered with soft rubber to further improve the anti-rust performance.

[0056] In one embodiment, there is a movable gap between adjacent movable seats 121, and a sponge pad is provided in the movable gap, and the sponge pad is adhered to the movable seat 121. Since adjacent movable seats 121 are connected by a first hinge 122, and the first hinge 122 has a first pivot 1223, and the first pivot 1223 is located between adjacent movable seats 121, there is a movable gap between adjacent movable seats 121. In order to improve the stability of the structure of the guardrail 12 and prevent the rigidity of the guardrail 12 from increasing, a sponge pad is provided in the movable gap, and the two sides of the sponge pad are respectively glued to the adjacent movable seats 121. When the guardrail 12 is hit, the sponge pad is separated from one of the movable seats 121, so that the guardrail 12 can be bent, reducing the damage caused by the impact.

[0057] In addition, the sponge pad can also be replaced by two Velcro strips that adhere to each other. The two Velcro strips are respectively installed on adjacent movable seats 121 and are located in the movable gap.

[0058] In one embodiment, the lane gate also includes a sensor installed on the guardrail 12, which is an in-position detection sensor, an infrared detection sensor, etc., which can detect whether there are vehicles or pedestrians under the guardrail 12, thereby controlling the drive to stop driving the guardrail 12 to rotate.

[0059] In one embodiment, the base 11 includes a housing having a machine cavity. The driver is a motor, which is installed in the machine cavity. The barrier 12 is located outside the machine cavity, and the output shaft of the motor is connected to the connecting seat 124.

[0060] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
