Abstract
Description
Technical Field
[0001] This utility model belongs to the field of barrier gate technology, specifically relating to a barrier gate with buffer and anti-collision protection function. Background Technology
[0002] A barrier gate, also known as a vehicle barrier, is a specialized access control device used on roads to restrict the movement of motor vehicles. It is widely used in highway toll stations, parking lots, residential communities, and the entrances of businesses and institutions to manage vehicle access. The mechanical components of a barrier gate typically consist of a housing, motor, reducer, transmission mechanism, and barrier arm. The housing supports and drives the barrier arm's rotation via a shaft in the transmission mechanism, enabling the barrier arm to stably block and rotate. However, in practical use, some shortcomings remain. When a vehicle accidentally impacts the barrier arm, the connection between the barrier arm and the main shaft on one side of the housing is relatively fixed. When the impact force is large, the damage between the vehicle and the barrier arm is severe. The barrier arm is prone to bending and breakage, and the vehicle is also severely damaged. Furthermore, the barrier arm pulls on the transmission mechanism, causing damage to the internal transmission mechanism of the housing, resulting in high maintenance costs. Additionally, the vehicle's trajectory after impacting the barrier is affected by the barrier's obstruction, leading to unstable driving and a risk of rebound and loss of control, thus increasing safety hazards to pedestrians and other vehicles. Utility Model Content
[0003] This utility model provides a barrier gate with buffer and anti-collision protection function, which has the characteristics of reducing the degree of damage to vehicles and barrier gates.
[0004] This utility model provides the following technical solution: It includes a chassis and a rotary drive shaft. The rotary drive shaft is hinged to a connecting plate. A rotary support plate is provided at one end of the rotary drive shaft. The connecting plate is installed on one side of the rotary support plate. A railing is provided at one end of the rotary support plate. A slot is opened at one end of the rotary support plate. An insert plate is fixedly connected to one end of the railing. The insert plate is inserted into the inner wall of the slot. Two limiting wedges are slidably connected to the inner wall of the rotary support plate. Two return springs are fixedly connected to one end of each limiting wedge. Slots are opened at both ends of the insert plate. The limiting wedges are engaged with the inner walls of the corresponding slots. Two fixed tubes are installed on one side of the rotary support plate. Telescopic slide rods are slidably connected to the inner walls of the fixed tubes. A buffer spring is fixedly connected between the fixed tubes and the telescopic slide rods. A touch pressure sensor is installed inside the fixed tube. The telescopic slide rod contacts the corresponding touch pressure sensor.
[0005] The chassis is rotatably connected to a rotating ring on one side, and both telescopic slide rods are slidably connected to one side of the rotating ring.
[0006] The rotating support plate has two traction ropes slidably connected to its inner wall. One end of each traction rope is fixedly connected to one end of the corresponding limiting wedge. The rotating support plate has a clearance groove, and the inner wall of the clearance groove is rotatably connected to a winding bearing for winding the two traction ropes.
[0007] The rotating support plate has a groove, and a push plate is slidably connected to the inner wall of the groove. A compression spring is fixedly connected to the inner wall of the groove to push the push plate outward. The push plate is in contact with one end of the insert plate.
[0008] The inner wall of the chute is fixedly connected to two limiting cones, and the upper and lower ends of the push plate are provided with notches. The limiting cones are slidably connected to the inner wall of the corresponding notches.
[0009] The beneficial effects of this utility model are as follows: by using a buffer spring to push the telescopic sliding rod, the rotating support plate and the railing have a buffering and anti-collision protective effect, reducing impact damage; by using a separate connection between the rotating support plate and the railing, the rotating support plate can quickly separate from the railing after the vehicle hits the railing and reaches the upper limit of pressure. The timely separation of the railing improves the stability of the vehicle's trajectory and driving state after the impact, and the railing no longer has the risk of rebounding and losing control, thereby reducing the safety hazards to surrounding pedestrians and other vehicles.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: including a chassis 1 and a rotary drive shaft 11, the rotary drive shaft 11 is hinged to a connecting plate 12, a rotary support plate 2 is provided at one end of the rotary drive shaft 11, the connecting plate 12 is installed on one side of the rotary support plate 2, a railing 3 is provided at one end of the rotary support plate 2, a slot 21 is opened at one end of the rotary support plate 2, an insert plate 31 is fixedly connected to one end of the railing 3, the insert plate 31 is inserted into the inner wall of the slot 21, two limiting wedges 22 are slidably connected to the inner wall of the rotary support plate 2, two return springs 221 are fixedly connected to one end of the limiting wedges 22, slots 32 are opened at both ends of the insert plate 31, the limiting wedges 22 are engaged with the inner wall of the corresponding slots 32, two fixing tubes 4 are installed on one side of the rotary support plate 2, a telescopic slide rod 41 is slidably connected to the inner wall of the fixing tube 4, a buffer spring 42 is fixedly connected between the fixing tube 4 and the telescopic slide rod 41, a touch pressure sensor 43 is installed inside the fixing tube 4, and the telescopic slide rod 41 contacts the corresponding touch pressure sensor 43.
[0018] In this implementation scheme: The chassis 1 supports all components of the device. The chassis 1 drives the connecting plate 12 to rotate via the rotary drive shaft 11. The connecting plate 12 supports and drives the rotary support plate 2. The rotary support plate 2 makes way for the insert plate 31 via the slot 21. The barrier 3 is connected to the rotary support plate 2 via the insert plate 31. The barrier 3 intercepts and blocks vehicles at the gate. After the barrier 3 drives the insert plate 31 to insert into the slot 21, the two limiting wedges 22 in the rotary support plate 2 are distributed vertically at both ends of the bottom of the insert plate 31. The end of the insert plate 31 is arc-shaped, allowing the end of the insert plate 31 to pass normally over the two limiting wedges 22. The insert plate 31 presses against the two limiting wedges 22, causing the limiting wedges 22 to retract. Inside the rotating support plate 2, when the two slots 32 on the insert plate 31 reach the corresponding limit wedge 22 positions, the return spring 221 pushes the limit wedge 22, allowing the limit wedge 22 to engage in the slot 32, thereby limiting the insert plate 31 and fixing it inside the slot 21. The rotating support plate 2 and the railing 3 are then installed and locked, making installation quick and convenient. The rotating support plate 2 supports the two fixed tubes 4, which in turn support the corresponding telescopic slide rod 41. The buffer spring 42 pushes the telescopic slide rod 41 outward, allowing it to extend stably towards the chassis 1. The two fixed tubes 4 are located on both sides of the connecting plate 12. When the rotating support plate 2 is not pushed... In the case of a vehicle accidentally hitting the barrier gate 3, the two fixed tubes 4 and the telescopic slide rod 41 keep the rotating support plate 2 flush with the housing 1. When the vehicle accidentally hits the barrier gate 3, the barrier gate 3 causes the rotating support plate 2 to tilt, with one end of the rotating support plate 2 tilting closer to the housing 1. The rotating support plate 2 causes the fixed tubes 4 and the buffer spring 42 to press the telescopic slide rod 41, causing the telescopic slide rod 41 to retract into the fixed tubes 4 due to the reaction force of the housing 1. As the vehicle continues to push the barrier gate 3, the telescopic slide rod 41 can slide to the position of the pressure sensor 43 and press it, causing the pressure sensor 43 to be sensed. The pressure sensor 43 sends a signal command to the transmission mechanism inside the rotating support plate 2, causing the transmission mechanism inside the rotating support plate 2 to activate. The mechanism can control the retraction of the two limiting wedges 22, thereby unlocking the rotating support plate 2 and the insert plate 31. The railing 3 then pulls the insert plate 31 away from the rotating support plate 2, preventing the railing 3 and the rotating support plate 2 from continuing to pull the rotating drive shaft 11 and the transmission mechanism inside the housing 1, thus preventing damage to the transmission mechanism inside the housing 1 and reducing later maintenance costs. Furthermore, after the rotating support plate 2 and the railing 3 separate, the timely separation of the railing 3 improves the stability of the vehicle's trajectory and driving state after the collision. The railing 3 no longer has the risk of rebounding and losing control, thereby reducing the safety hazards to surrounding pedestrians and other vehicles. At the same time, the buffer spring 42 gives the rotating support plate 2 and the railing 3 a buffer and anti-collision protective effect.
[0019] A rotating ring 13 is rotatably connected to one side of the chassis 1, and two telescopic slide rods 41 are slidably connected to one side of the rotating ring 13. The rotating ring 13 is kept flush with one side of the chassis 1. The chassis 1 contacts the ends of the two telescopic slide rods 41 through the rotating ring 13. When the rotating drive shaft 11 drives the rotating support plate 2 and the railing 3 to rotate, the rotating support plate 2 drives the two fixed pipes 4 and the telescopic slide rods 41 to rotate. The rotating ring 13 can follow the telescopic slide rods 41 to rotate through friction, thereby reducing friction loss and resistance.
[0020] Two traction ropes 23 are slidably connected to the inner wall of the rotating support plate 2. One end of each traction rope 23 is fixedly connected to one end of a corresponding limiting wedge 22. A clearance groove 24 is provided inside the rotating support plate 2. A winding bearing 231 for winding the two traction ropes 23 is rotatably connected to the inner wall of the clearance groove 24. The winding bearing 231 is driven by a motor inside the rotating support plate 2. The ends of the two traction ropes 23 are fixed to the side wall of the winding bearing 231. When the winding bearing 231 rotates, it winds up the two traction ropes 23. The clearance groove 24 provides clearance and storage space for the winding bearing 231 and the wound traction ropes 23. The clearance groove 24 is opened by an electrical signal emitted by a touch pressure sensor 43. When the traction ropes 23 are wound up, they pull the corresponding limiting wedge 22, enabling the limiting wedge 22 to unlock the insert plate 31.
[0021] The rotating support plate 2 has a groove 25 inside, and a push plate 26 is slidably connected to the inner wall of the groove 25. A compression spring 251 is fixedly connected to the inner wall of the groove 25 to push the push plate 26 outward. The push plate 26 is in contact with one end of the insert plate 31. The groove 25 guides the push plate 26 to slide, and the compression spring 251 pushes the push plate 26 outward, so that the push plate 26 can be pushed towards the insert plate 31. After the limit wedge block 22 unlocks the insert plate 31, the push plate 26 can push the insert plate 31 out, so that the railing 3 can quickly separate from the rotating support plate 2 and reduce damage to the gate.
[0022] Two limiting cones 252 are fixedly connected to the inner wall of the slide groove 25. The upper and lower ends of the push plate 26 are provided with notches 261. The limiting cones 252 are slidably connected to the inner wall of the corresponding notches 261. The push plate 26 makes way for the limiting cones 252 through the notches 261, and the limiting cones 252 limit the push plate 26 to prevent the push plate 26 from detaching from the slide groove 25.
[0023] The working principle and usage process of this utility model are as follows: When a vehicle accidentally hits the barrier gate 3, the barrier gate 3 causes the rotating support plate 2 to tilt. One end of the rotating support plate 2 tilts closer to the housing 1. The buffer spring 42 provides a buffering and anti-collision protection effect for the rotating support plate 2 and the barrier gate 3, reducing impact damage. As the vehicle continues to push the barrier gate 3, the telescopic slide bar 41 is subjected to the reaction force of the housing 1 and retracts into the fixed tube 4. The telescopic slide bar 41 slides to the position of the pressure sensor 43 and presses it, causing the pressure sensor 43 to be sensed. Sensor 43 sends a signal command to the motor inside the rotating support plate 2. The motor winds up the two traction ropes 23 through the winding bearing 231. The traction ropes 23 pull the limit wedge block 22 to retract, completing the unlocking work between the rotating support plate 2 and the railing 3. At the same time, the compression spring 251 pushes the push plate 26 outward, so that the push plate 26 can be pushed towards the insertion plate 31. After the limit wedge block 22 unlocks the insertion plate 31, the push plate 26 can push the insertion plate 31 out, so that the railing 3 can quickly separate from the rotating support plate 2, reducing damage to the gate.
