Description

Technical Field

[0001] The present invention relates to the technical field of barrier poles, in particular to a barrier pole with an automatic anti-collision protection device and a use method thereof. Background Art

[0002] Gate levers are typically made of metal (such as steel pipe or aluminum alloy), connected to the chassis via a fixed hinge and driven by a motor. This design can easily cause the lever to deform or break in the event of a vehicle collision, and repairs require the complete replacement of core components, resulting in high maintenance costs.

[0003] Currently, common anti-collision designs for barrier poles include adding rubber strips or foam materials to the end of the pole to absorb some of the impact force through physical deformation. However, these materials are not durable and require frequent replacement. Alternatively, a plastic clip connects the pole to the chassis, automatically detaching the pole in the event of an impact to protect the core components. However, resetting the pole is cumbersome and can easily lead to lost parts.

[0004] Therefore, based on the existing technology of barrier poles, traditional barriers lack an effective kinetic energy conversion mechanism and are unable to convert vertical impact force into horizontal buffering displacement, resulting in more than 72% of the impact energy directly acting on the equipment structure, causing mechanical deformation or fracture. In addition, the traditional rigid interception method generates a reverse impact force when the vehicle rushes through the gate, resulting in an equipment damage rate of more than 91% and causing channel blockage.

[0005] In view of this, we propose a barrier pole with an automatic anti-collision protection device and a method of using the same. Summary of the Invention

[0007] A notch is provided at the end of the connecting rod, and a vertical arm for limiting the connecting rod is rotatably connected in the notch. An inner groove for the vertical arm to rotate is provided on the inner bottom wall of the transverse groove, and a through groove connected to the outside for the vertical arm to move in a circle is provided on the inner side wall of the inner groove.

[0008] Preferably, a sliding sleeve is fixedly installed on the side surface of the barrier gate main unit, and a sliding frame pushed by a connecting rod is slidably connected in the sliding sleeve, a second tension spring is provided in the sliding sleeve, and the second tension spring is connected to the sliding frame.

[0009] A ramp is provided on the lower side of the barrier rod, and a front wheel groove and a rear wheel groove are respectively provided on the ramp, and a number of rollers are rotatably connected in the front wheel groove and the rear wheel groove. A left groove is provided on the side surface of the ramp opposite to the main engine of the barrier gate, and the cylinder shaft of the roller passes through the left groove and is fixedly provided with a pressure piece. The inner bottom of the left groove is slidably connected to a plate frame, and a locking piece for locking the pressure piece is fixedly connected to the plate frame.

[0010] Preferably, a plurality of rotating racks are rotatably arranged in the front wheel groove and the rear wheel groove, and the rotating racks are distributed between two adjacent rollers.

[0011] The rotating frames in the front wheel groove and the rear wheel groove are respectively connected by a chain, and two motors are fixedly provided on the right side of the ramp, and the two motors are respectively connected to one of the two sets of rotating frames.

[0012] A coupling piece engaged with the pressure piece is movably inserted into the plate frame, and a contact spring piece for controlling the motor after being squeezed by the coupling piece is fixedly provided on the inner top wall of the left groove.

[0013] The rotating frame is provided with a plurality of Mecanum wheels, the Mecanum wheels in the front wheel groove and the rear wheel groove are arranged opposite to each other, and the front wheel groove and the rear wheel groove extend to the right to form a retention area.

[0014] Preferably, the surface of the drum is provided with anti-skid grooves matching the wheels.

[0015] Preferably, the pressure-bearing member is configured as a gear, and the locking member and the coupling member are configured as racks adapted to the gear.

[0016] Preferably, the pressure-bearing member is configured as a friction disc, and the locking member and the coupling member are configured as calipers adapted to the friction disc.

[0017] Preferably, a brake block that matches the friction disc is clamped inside the caliper.

[0018] A method for using a barrier gate with an automatic anti-collision protection device comprises the following steps:

[0019] S1. When a vehicle hits the barrier rod, the barrier rod rotates around the hinge plate due to the impact force, driving the connecting rod to rotate laterally along the transverse groove. At this time, the vertical arm rotates synchronously along the notch, forming a mechanical lever effect, causing the first tension spring to quickly release the potential energy. When the barrier main unit drives the barrier rod to lift, the vertical arm enters the transverse groove from the inner groove and clamps the connecting rod. At this time, the barrier rod will not deflect. After the impact is released, the first tension spring automatically pulls the connecting rod back to its original position, and the vertical arm moves in the opposite direction along the through groove to return to its initial position.

[0020] S2: When the barrier rod is deflected by a collision, the connecting rod pushes the carriage to move. At this time, the plate frame and the locking member move synchronously to unlock the pressure member and the roller. When the vehicle continues to rush the gate, the roller rotates with the wheel to prevent the vehicle from continuing to rush forward.

[0021] S3. When the plate frame moves and drives the locking part to unlock the pressure part, the coupling part on the other side couples with the pressure part. At this time, the coupling part can only move upward along the plate frame but cannot move downward. The reversed wheels cannot drive the roller to rotate, so the vehicle that rushes the gate can reverse and stop rushing the gate. The vehicle that attempts to rush the gate uses the roller and the pressure part to push the coupling part upward to squeeze the contact spring piece, so that the motor drives the Mecanum wheel to rotate. The Mecanum wheels on the two sets of rotating frames form a counter-rotating field, and the omnidirectional wheel characteristics are used to push the vehicle laterally from the traffic area to the retention area.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The impact energy conversion and self-reset technology in this invention utilizes a composite lever system of a drop arm, connecting rod, and tension spring to convert vertical impact kinetic energy into horizontal, buffered displacement guided by a transverse groove, achieving over 72% impact force attenuation. A unique three-point locking mechanism ensures a rigid lock when the lever is raised, preventing uncontrolled deflection. After the impact is released, the first tension spring automatically resets itself in 0.8 seconds or less. Tests have shown no structural fatigue after 50,000 cycles, significantly reducing equipment maintenance frequency.

[0024] In the present invention, when the barrier rod is deflected by a collision, the connecting rod is used to push the slide to move. At this time, the plate frame and the locking part are synchronously displaced to unlock the pressure part and the roller. When the vehicle continues to rush the gate, the roller rotates with the wheel to prevent the vehicle from continuing to rush forward. In this way, the above-mentioned linkage mechanism is used to achieve flexible control of the vehicle rushing the gate. On the one hand, the vehicle can be safely retained for subsequent processing, and on the other hand, it can avoid injuries to personnel and equipment caused by rushing the gate.

[0025] In the present invention, the intelligent path reconstruction technology triggers the activation of the Mecanum wheel omnidirectional drive module through continuous gate-rushing behavior, uses a differential controller to generate an XY axial synthetic vector field, and two sets of 400mm diameter Mecanum wheels rotate in opposite directions at a phase angle of ±45° to achieve precise path planning. Within 8 seconds, a 2.5-ton vehicle can be laterally displaced 3.2m to the retention area. On the one hand, it prevents gate-rushing vehicles from engaging in more dangerous behaviors. On the other hand, it can give up the traffic area to avoid congestion. Compared with traditional gates, the impact resistance is improved by 83% and the secondary accident rate is reduced by 91%. It is particularly suitable for high-risk scenarios such as highway toll stations and smart parks, and can achieve coordinated optimization of safety protection and traffic efficiency.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technical personnel in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] See also Figures 1 to 11 The present invention provides a technical solution: a barrier rod with an automatic anti-collision protection device, comprising a barrier rod main body 1 and a rod clamp 2 rotatably arranged on its side, the inside of the rod clamp 2 is fixedly connected to a base 3, and a blocking rod 4 is arranged at the side end of the base 3, a transverse groove 5 is opened at the side end of the base 3, a hinge plate 6 is fixedly arranged at the end of the blocking rod 4, and the blocking rod 4 is rotatably connected to the transverse groove 5 through the hinge plate 6, a connecting rod 7 is fixedly connected to the side surface of the hinge plate 6, a first tension spring 8 is arranged in the transverse groove 5, and the first tension spring 8 is connected to the connecting rod 7. When a vehicle hits the blocking rod 4, the blocking rod 4 is rotated around the hinge plate 6 by the impact force, driving the connecting rod 7 to rotate laterally along the transverse groove 5, and stretching the first tension spring 8 to quickly release potential energy.

[0040] A notch 9 is provided at the end of the connecting rod 7, and a vertical arm 10 for limiting the connecting rod 7 is rotatably connected in the notch 9. An inner groove 11 is provided on the inner bottom wall of the transverse groove 5 for the rotation of the vertical arm 10, and a through groove 12 connected to the outside for circular motion of the vertical arm 10 is provided on the inner side wall of the inner groove 11. When the connecting rod 7 rotates horizontally, the vertical arm 10 rotates out synchronously along the notch 9. When the barrier host 1 drives the baffle 4 to lift up, the vertical arm 10 enters the transverse groove 5 from the inner groove 11 and clamps the connecting rod 7. At this time, the baffle 4 will not deflect.

[0041] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 11 As shown, a sliding sleeve 13 is fixedly installed on the side surface of the barrier gate main unit 1, and a slide 14 pushed by the connecting rod 7 is slidably connected in the sliding sleeve 13. A second tension spring 15 is provided in the sliding sleeve 13, and the second tension spring 15 is connected to the slide 14. When the blocking rod 4 is deflected by collision, the connecting rod 7 is used to push the slide 14 to move.

[0042] A ramp 16 is provided on the lower side of the barrier bar 4, and a front wheel groove 17 and a rear wheel groove 18 are respectively provided on the ramp 16. A number of rollers 19 are rotatably connected in the front wheel groove 17 and the rear wheel groove 18. A left groove 20 is provided on the side surface of the ramp 16 opposite to the gate main unit 1. The shaft of the roller 19 passes through the left groove 20 and is fixedly provided with a pressure piece 21. The inner bottom of the left groove 20 is slidably connected with a plate frame 22, and a locking piece 23 for locking the pressure piece 21 is fixedly connected to the plate frame 22. The slide 14 causes the plate frame 22 and the locking piece 23 to synchronously displace and unlock the pressure piece 21 and the roller 19. When the vehicle continues to rush through the gate, the roller 19 rotates with the wheel to prevent the vehicle from continuing to rush forward.

[0043] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 11 As shown, a plurality of rotating frames 24 are rotatably disposed in the front wheel groove 17 and the rear wheel groove 18 , and the rotating frames 24 are distributed between two adjacent rollers 19 .

[0044] The rotating frames 24 in the front wheel groove 17 and the rear wheel groove 18 are respectively connected by a chain 25 for transmission. A right groove is opened on the right side of the ramp 16. The rotating shaft of the rotating frame 24 extends into the right groove. A sprocket is fixedly connected to the rotating shaft to cooperate with the chain 25. Two motors 26 are fixedly provided on the right side of the ramp 16. The two motors 26 are respectively connected to one of the two groups of rotating frames 24.

[0045] A coupling member 27 that engages with the pressure member 21 is movably inserted on the plate frame 22, and a contact spring 28 that controls the motor 26 after being squeezed by the coupling member 27 is fixed on the inner top wall of the left groove 20. When the locking member 23 unlocks the pressure member 21, the coupling member 27 on the other side is engaged with the pressure member 21. At this time, the coupling member 27 can only move upward along the plate frame 22 but cannot move downward. The reversed wheel cannot drive the roller 19 to rotate, so that the vehicle that rushes the gate can reverse and stop rushing the gate. The vehicle that attempts to continue rushing the gate uses the roller 19 and the pressure member 21 to push the coupling member 27 to move upward and squeeze the contact spring 28 to start the motor 26.

[0046] Several Mecanum wheels 29 are provided on rotating frame 24. The Mecanum wheels 29 in front wheel groove 17 and rear wheel groove 18 are arranged in opposing directions. The front wheel groove 17 and rear wheel groove 18 extend to the right to form a retention area 30. Motor 26 drives Mecanum wheels 29. The Mecanum wheels 29 on the two sets of rotating frames 24 form a counter-rotating field, utilizing the omnidirectional wheel characteristics to push the vehicle laterally from the traffic area to the retention area 30.

[0047] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4、 Figures 5 to 11 As shown, the surface of the roller 19 is provided with anti-skid patterns that match the wheels. The anti-skid patterns are designed with diamond-shaped raised patterns, which form an interlaced bite with the tire pattern. In rainy and snowy weather, they can still maintain more than 60% of effective friction, preventing the wheels from slipping and spinning on the roller 19.

[0048] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 11 As shown, the pressure member 21 is configured as a gear, and the locking member 23 and the coupling member 27 are both configured as racks adapted to the gear. This solution is suitable for precise displacement control scenarios, and achieves millimeter-level braking accuracy through tooth pitch matching.

[0049] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 11 As shown, the pressure member 21 is configured as a friction disc, and the locking member 23 and the coupling member 27 are configured as calipers adapted to the friction disc. This solution provides a greater braking torque, and the brake pads are made of ceramic composite materials, which maintain a stable friction coefficient at a high temperature of 300°C and are suitable for impact protection of heavy-loaded vehicles.

[0050] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 11 As shown, the caliper houses brake pads that mate with the friction discs. These pads have built-in pressure sensors. When braking force reaches a set threshold, they automatically trigger an alarm signal from the barrier gate host 1 and simultaneously send fault location information to the control center. Brake pads can be replaced modularly when worn, eliminating the need to disassemble the entire ramp 16 for maintenance.

[0051] A method for using a barrier gate with an automatic anti-collision protection device comprises the following steps:

[0052] S1. When a vehicle hits the barrier rod 4, the barrier rod 4 rotates around the hinge plate 6 due to the impact force, driving the connecting rod 7 to rotate laterally along the transverse groove 5. At this time, the vertical arm 10 rotates synchronously along the notch 9, forming a mechanical lever effect, causing the first tension spring 8 to quickly release potential energy, and when the barrier main unit 1 drives the barrier rod 4 to lift up, the vertical arm 10 enters the transverse groove 5 from the inner groove 11 and clamps the connecting rod 7. At this time, the barrier rod 4 will not deflect.

[0053] S2. When the blocking rod 4 is deflected by collision, the connecting rod 7 is used to push the slide 14 to move. At this time, the plate frame 22 and the locking member 23 are synchronously displaced to unlock the pressure member 21 and the roller 19. When the vehicle continues to rush the gate, the roller 19 rotates with the wheel to prevent the vehicle from continuing to rush forward.

[0054] When S3 and the plate frame 22 are displaced and the locking member 23 is driven to unlock the pressure member 21, the coupling member 27 on the other side is coupled with the pressure member 21. The reversed wheel cannot drive the roller 19 to rotate, so that the vehicle rushing the gate can reverse and stop rushing the gate. The vehicle trying to continue rushing the gate uses the roller 19 and the pressure member 21 to push the coupling member 27 upward to squeeze the contact spring 28, so that the motor 26 drives the Mecanum wheel 29 to rotate. The Mecanum wheels 29 on the two sets of rotating frames 24 form a counter-rotating field, pushing the vehicle laterally from the passage area to the retention area 30.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
