Description

Technical Field

[0001] This utility model relates to a lifting barrier, and more particularly to a lifting barrier for highway toll stations. Background Technology

[0002] Toll booths are facilities used to collect tolls from passing vehicles. Toll roads can be divided into two categories: open and closed. Open toll roads, also known as fenced toll roads, typically have toll booths located on the main road, and vehicles pay tolls based on the number of times they pass through. Open toll roads can be further divided into one-way and two-way toll roads. Open toll roads are often used for independent bridges, tunnels, and roads without controlled access. Closed toll roads are mostly used for expressways with controlled access, where vehicle users pay tolls based on the distance traveled into and out of the road.

[0003] In actual use, existing tollbooth lifting barriers can cause situations where drivers are careless and fail to brake in time, resulting in the front of the vehicle entering under the barrier. This causes the car's hood to come into contact with the barrier, forcing it to rise to a certain height. The pressure from the barrier can damage the paint on the car's exterior, causing losses to the owner. At the same time, the forced rise of the barrier can also cause irreversible damage to the equipment and transmission components.

[0004] A search revealed that announcement number CN219772803U discloses a rising barrier for highway toll stations, comprising a base plate. A barrier control box is fixedly connected to the upper end of one side of the base plate. A door is located on the front of the barrier control box, and a rotating mechanism is installed on the rear side. A support assembly is installed on the upper end of the base plate near the other side. The rotating mechanism includes a fixed rod fixedly mounted on a rotating shaft on the rear side of the barrier control box. A fixed housing is fixedly installed on one side of the fixed rod, and a movable rod is located inside the fixed housing. Rotating shaft blocks are fixedly connected to the upper and lower ends of the movable rod near the inner side of the fixed housing. According to this utility model, when a vehicle hits the movable barrier, the movable rod rotates along its connection with the fixed housing, reducing the risk of damage upon impact within a certain distance.

[0005] When the above technical solution is used, if the situation occurs where "the front of the car enters under the railing, causing the car's hood to contact the railing and forcing the railing to rise to a certain height", the fixed bar will be forced to rise, and the pressure of the movable bar in the above solution will damage the paint on the car's exterior surface. Utility Model Content

[0006] The purpose of this utility model is to provide a lifting barrier for highway toll stations, which can adaptively raise the barrier when a car enters below it while the barrier is blocking traffic, thus solving the problem of damage to both the vehicle and the barrier itself.

[0007] This utility model adopts the following technical solution: a lifting barrier for highway toll stations, including a pile body, a rotating shaft is rotatably arranged inside the pile body in the front-to-back direction, the rear end of the rotating shaft protrudes from the rear side of the pile body and is fixedly arranged with an arm, the right end of the arm is connected to the barrier, a driving device is arranged inside the pile body, the output end of the driving device is fixedly arranged with the rotating shaft, the driving device drives the barrier to rotate through the rotating shaft and the arm; the arm includes an upper arm and a lower arm, the left end of the upper arm is fixedly arranged with the rotating shaft, the right end of the upper arm is hinged to the lower arm, the right end of the lower arm is connected to the barrier, a damping mechanism is arranged between the lower arm and the upper arm, the damping mechanism prevents the upper arm from rotating with a set pressure.

[0008] Furthermore, the damping mechanism includes two L-plates fixedly mounted on the upper and lower ends of the upper arm, and a vertical rod slidably mounted in the horizontal portion of the L-plates in the vertical direction. A baffle is provided on the outer surface of the vertical rod located outside the L-plates. A pressure spring is sleeved on the vertical rod between the baffle and the horizontal portion of the L-plates. The two ends of the pressure spring are fixedly mounted to the baffle and the horizontal portion of the L-plates, respectively. A transmission mechanism is provided between the vertical rod and the lower arm.

[0009] Furthermore, the baffle and the vertical rod are slidably arranged in the vertical direction, and an adjusting nut is rotatably connected to the upper end face of the baffle. The adjusting nut is threadedly connected to the external thread on the outer surface of the vertical rod.

[0010] Furthermore, the transmission mechanism includes two connecting rods hinged to the upper and lower end faces of the lower arm, each connecting rod being hinged to a corresponding vertical rod.

[0011] Furthermore, the rear side of the lower arm has a long groove adapted to the railing along the left and right direction, and the left end of the railing is located in the long groove of the lower arm and is hinged to the lower arm.

[0012] Furthermore, the driving device includes a motor fixedly mounted on the rear side of the pile body, the output shaft of the motor extending into the interior of the pile body and fixedly mounted with a drive rod, and a transmission rod hinged to the end of the drive rod away from the motor output shaft.

[0013] Furthermore, an actuator is hinged to the top of the transmission rod, and the actuator end of the actuator is fixedly set to the rotating shaft.

[0014] Furthermore, the baffle is coaxially provided with a through hole, and the baffle is sleeved with the vertical rod through the through hole.

The baffle is slidably connected to the vertical rod in the vertical direction through the slide rail and the slide groove.

[0015] Furthermore, a circular groove is coaxially formed on one side of the baffle near the adjusting nut, and a collar is rotatably connected in the groove of the baffle. The collar is fixedly set with the adjusting nut, and the adjusting nut is rotatably connected to the baffle through the collar.

[0016] Furthermore, a cover is fixedly installed on the rear side of the pile, and the motor is located inside the cover.

[0017] I. By setting up an upper arm and a lower arm, when a car enters under the barrier, the car's hood contacts the barrier, forcing it to rise. At this time, the lower arm will overcome the set pressure of the damping mechanism and rotate upward relative to the upper arm. This allows the barrier to adapt to the external force of the car's hood, preventing damage to the paint on the car's exterior surface. It also prevents the upper arm from being forced to reverse, causing irreversible damage to the equipment.

[0018] II. This utility model, by setting up connecting rods, vertical rods, pressure springs, and baffles, allows the railing to be lifted by an external force when it is in a vehicle-blocking state. The upper arm rotates upward, pulling the pressure spring upward through the connecting rods, vertical rods, and baffles above. This causes the railing to overcome the tension of the pressure spring and lift upward, allowing it to adapt to the upward force. At the same time, the connecting rods, vertical rods, and baffles below move upward, causing the pressure spring below to rebound, thus preventing the railing from damaging the paint on the exterior of the car.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0028] Please see Figure 1-7 The lifting barrier for highway toll stations described in this utility model includes a pile body 1. A rotating shaft 2 is rotatably installed inside the pile body 1 in the front-to-back direction. The rear end of the rotating shaft 2 protrudes from the rear side of the pile body 1 and is fixedly installed with an arm 3. The right end of the arm 3 is connected to a barrier 4. A driving device is installed inside the pile body 1. The output end of the driving device is fixedly installed with the rotating shaft 2. The driving device drives the arm 3 to rotate through the rotating shaft 2, thereby driving the barrier 4 to rotate.

[0029] In operation, the drive unit drives the rotating shaft 2 to rotate, which in turn drives the arm 3 to rotate, causing the arm 3 to rotate the guardrail 4, thus raising and lowering the guardrail 4. In actual use, if the driver is negligent and fails to brake in time, the front of the car may drive under the guardrail 4, causing the car's hood to come into close contact with the guardrail 4. This forces the guardrail 4 to rise to a certain height, and the reaction force of the guardrail 4 can damage the paint on the car's exterior, causing losses to the owner. On the other hand, the forced rise of the guardrail 4 can also cause the drive unit to reverse through the arm 3 and the rotating shaft 2. Under normal circumstances, the drive unit usually has a self-locking function. Therefore, the rise of the guardrail 4 may lead to irreversible damage, such as damage to the drive unit or loosening of the connection between the arm 3 and the rotating shaft 2.

[0030] To address the aforementioned issues, in this embodiment, the boom 3 includes an upper boom 301 and a lower boom 302. The left end of the upper boom 301 is fixedly connected to the rotating shaft 2, and the right end of the upper boom 301 is hinged to the lower boom 302. The right end of the lower boom 302 is connected to the railing 4. A damping mechanism is provided between the lower boom 302 and the upper boom 301, which uses a set pressure to prevent the upper boom 301 from rotating. During normal use, the drive device drives the upper boom 301 to rotate via the rotating shaft 2. The rotation of the upper boom 301 causes the lower boom 302 to rotate synchronously, and the lower boom 302 causes the railing 4 to rotate synchronously, thus raising and lowering the railing 4. Although the upper boom 301 and the lower boom 302 are hinged, the damping mechanism prevents them from moving arbitrarily. The lower arm 302 will only rotate relative to the upper arm 301 when subjected to a pressure greater than the set pressure of the damping mechanism. In the event of an accident, if the driver is careless and fails to brake in time, causing the front of the car to enter under the barrier 4, and if the force exerted by the car's hood on the barrier 4 exceeds the set pressure of the damping mechanism, the barrier 4 will cause the lower arm 302 to rotate relative to the upper arm 301. The barrier 4 will adaptively lift when pushed by the car's hood, thus avoiding damage to the paint on the car's exterior surface. If the force exerted by the car's hood on the barrier 4 is less than the set pressure of the damping mechanism, the barrier 4 will not lift due to the damping mechanism. Since the force exerted by the hood on the barrier 4 is small, the barrier 4 will not damage the paint on the car's exterior surface.

[0031] In this embodiment, the damping mechanism includes two L-plates 5 fixedly disposed on the upper and lower ends of the upper arm 301, and a vertical rod 6 slidably disposed within the horizontal portion of the L-plates 5 in the vertical direction. A baffle 7 is disposed on the outer surface of the vertical rod 6 located outside the L-plates 5. A pressure spring 8 is sleeved on the vertical rod 6 between the baffle 7 and the horizontal portion of the L-plates 5. The two ends of the pressure spring 8 are fixedly disposed to the baffle 7 and the horizontal portion of the L-plates 5, respectively. A transmission mechanism is disposed between the vertical rod 6 and the lower arm 302. When the lower arm 302 rotates relative to the upper arm 301, it drives the vertical rod 6 to move up and down within the horizontal portion of the L-plates 5 through the transmission mechanism. The up and down movement of the vertical rod 6 drives the baffle 7 to move up and down. Taking the upper baffle 7 as an example, when the baffle 7 moves upward, it stretches the pressure spring 8. When the baffle 7 moves downward, the pressure spring 8 rebounds. When the lower arm 302 and the upper arm 301 are in a normal state, the pressure spring 8 is in a stretched state.

[0032] In the event of an accident, if the driver is careless and fails to brake in time, causing the front of the car to enter the barrier 4, and if the force exerted by the car's hood on the barrier 4 exceeds the set tension of the pressure spring 8, the barrier 4 will cause the lower arm 302 to rotate upward relative to the upper arm 301. This upward rotation of the lower arm 302, through a transmission mechanism, causes the upper vertical bar 6 to move upward. The upper vertical bar 6, through a baffle 7, causes the pressure spring 8 to stretch upward, causing the barrier 4 to overcome the tension of the pressure spring 8 and rise a certain distance. The barrier 4 is then pushed upward by the car's hood. When the car is moved, the pressure spring 8 pulls down the baffle 7, causing the upper vertical bar 6 to move downwards. This, in turn, drives the upper arm 301 to rotate downwards through the transmission mechanism until the lower arm 302 returns to a horizontal state. If the force exerted by the car's hood on the barrier 4 is less than the tension set by the pressure spring 8, the barrier 4 will not be raised due to the tension of the pressure spring 8. Since the force exerted by the hood on the barrier 4 is small, the barrier 4 will not damage the paint on the car's exterior surface.

[0033] To facilitate adjustment of the tension of the pressure spring 8, in this embodiment, the baffle 7 and the vertical rod 6 are slidably arranged in the vertical direction. An adjusting nut 9 is rotatably connected to the upper end face of the baffle 7, and the adjusting nut 9 is threadedly connected to the external thread on the outer surface of the vertical rod 6. When it is necessary to adjust the tension of the pressure spring 8, the adjusting nut 9 is rotated, causing the adjusting nut 9 to move up and down on the vertical rod 6, thereby driving the baffle 7 to move up and down. The up and down movement of the baffle 7 changes the distance between the baffle 7 and the horizontal part of the L plate 5, thereby changing the set tension of the pressure spring 8. During the initial assembly of the lower arm 302 and the upper arm 301, the upper arm 301 can be made to be in a horizontal state, and then the lower arm 302 can be observed to be in a horizontal state. If the lower arm 302 is not horizontal, it can be adjusted to a horizontal state by rotating the corresponding adjusting nut 9.

[0034] In this embodiment, a through hole 10 is coaxially provided on the baffle 7. The baffle 7 is sleeved with the vertical rod 6 through the through hole 10. A slide rail 11 is fixedly provided on the inner side wall of the through hole 10 of the baffle 7. A slide groove 12 is provided on the outer surface of the vertical rod 6 in the vertical direction. The baffle 7 is slidably connected to the vertical rod 6 in the vertical direction through the slide rail 11 and the slide groove 12.

[0035] In this embodiment, a circular groove 13 is coaxially formed on one side of the baffle 7 near the adjusting nut 9. A collar 14 is rotatably connected in the circular groove 13 of the baffle 7. The collar 14 is fixedly set with the adjusting nut 9, and the adjusting nut 9 is rotatably connected to the baffle 7 through the collar 14. When the adjusting nut 9 is rotated, the adjusting nut 9 drives the collar 14 to rotate in the circular groove 13 of the baffle 7. The adjusting nut 9 is threadedly engaged with the vertical rod 6. The adjusting nut 9 rotates and moves up and down on the vertical rod 6, thereby driving the baffle 7 to move up and down on the vertical rod 6, so as to achieve the purpose of adjusting the tension of the pressure spring 8.

[0036] In order to enable the lower arm 302 to rotate and drive the vertical rod 6 to move up and down through the transmission mechanism, in this embodiment, the transmission mechanism includes two connecting rods 15 hinged to the upper and lower end faces of the lower arm 302, and each connecting rod 15 is hinged to the corresponding vertical rod 6. When the upper arm 301 rotates upward, it drives the upper vertical rod 6 to move upward through the upper connecting rod 15, so that the vertical rod 6 stretches the upper pressure spring 8 through the baffle 7. If the railing 4 is raised by the rotation of the lower arm 302 relative to the upper arm 301, it needs to overcome the tension of the pressure spring 8.

[0037] During the use of the guardrail 4, another situation is likely to occur: when a car drives to the guardrail 4, it does not stop and directly crashes through the guardrail 4, causing damage to both the guardrail 4 and the car. To solve this problem, in this embodiment, the rear side of the lower arm 302 is provided with a long groove 16 adapted to the guardrail 4 in the left-right direction. The left end of the guardrail 4 is located in the long groove 16 of the lower arm 302 and is hinged to the lower arm 302. When a car crashes through the guardrail, the guardrail 4 will rotate backward due to the force, preventing the car from causing serious damage to the guardrail 4, and also preventing the car from being seriously damaged.

[0038] To achieve the raising and lowering of the barrier 4, thus enabling vehicles to pass through, in this embodiment, the driving device includes a motor 17 fixedly mounted on the rear side of the pile body 1. The output shaft of the motor 17 extends into the pile body 1 and is fixedly mounted with a drive rod 18. A transmission rod 19 is hinged to one end of the drive rod 18 away from the output shaft of the motor 17. An execution rod 20 is hinged to the top of the transmission rod 19. The execution end of the execution rod 20 is fixedly mounted with the rotating shaft 2. The rotation of the motor 17 drives the drive rod 18 to rotate, and the rotation of the drive rod 18 drives the execution rod 20 to rotate through the transmission rod 19. This rotation of the execution rod 20 drives the rotating shaft 2 to rotate. The rotating shaft 2 rotates sequentially through the upper arm 301, the lower arm 302, and the barrier 4, thereby raising and lowering the barrier 4, and thus achieving the purpose of stopping vehicles and enabling passage.

[0039] In this embodiment, a cover 21 is fixedly installed on the rear side of the pile body 1, and the motor 17 is located inside the cover 21.

[0040] The working principle of this utility model is as follows: In use, the motor 17 sequentially drives the barrier 4 to rise and fall via the drive rod 18, transmission rod 19, execution rod 20, rotating shaft 2, upper arm 301, and lower arm 302, realizing the normal function of stopping vehicles and allowing passage. When a car runs through the barrier, the barrier 4 will rotate backward within the long groove 16 of the lower arm 302 to avoid direct impact damage from the car. When a driver fails to brake in time, causing the front of the car to enter under the barrier 4, if the force of the car's hood forcing the barrier 4 to rise exceeds the set tension of the pressure spring 8, the barrier 4 will drive the lower arm 302 to rotate upward relative to the upper arm 301. The upward rotation of the lower arm 302 drives the upper vertical bar 6 to move upward through the connecting rod 15 above. When the car moves, the upper vertical bar 6 is pulled upward by the pressure spring 8 through the baffle 7, causing the railing 4 to rise a certain distance against the tension of the pressure spring 8. When the railing 4 is pushed by the car's hood, it rises, avoiding damage to the paint on the car's exterior surface. After the car moves away, the pressure spring 8 pulls the baffle 7 downward, causing the upper vertical bar 6 to move downward, which in turn drives the upper arm 301 to rotate downward through the connecting rod 15 until the lower arm 302 returns to the horizontal state. If the force of the car's hood forcing the railing 4 to rise is less than the tension set by the pressure spring 8, the railing 4 will not rise due to the tension of the pressure spring 8. Since the force of the hood forcing the railing 4 to rise is small, the railing 4 will not damage the paint on the car's exterior surface.
