Description

Technical Field

[0001] This invention relates to the technical field of road blocking devices for highways, specifically a road blocking device for preventing vehicles from breaking through toll stations on highways. Background Technology

[0002] Highway maintenance costs are high. To extend the lifespan of highways, weighing devices are installed at highway toll booths. However, in daily life, some drivers often attempt to evade toll booths for personal gain.

[0003] Typically, highway tollbooth workers will place sharp objects such as nails at the tollbooth entrances and exits, and when a vehicle tries to rush through, the workers will pull them away to prevent the vehicle from recklessly breaking through.

[0004] However, deploying such spiked defensive devices at highway toll station exits can harm unsuspecting pedestrians, and if a vehicle attempts to break through the toll gate, a punctured tire could cause it to lose control, making the extent of injury to the driver unpredictable. Therefore, this paper proposes a highway toll station anti-vehicle-breaking roadblock device to address these issues. Summary of the Invention

[0005] To address the shortcomings of existing technologies, deploying such spiked defensive devices at highway toll station exits can cause harm to unsuspecting pedestrians. Furthermore, after a vehicle attempts to breach the toll gate, a punctured tire can lead to loss of vehicle control, making the extent of injury to the driver unpredictable. This invention proposes a highway toll station anti-vehicle breaching road obstruction device.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a highway toll station anti-vehicle road obstruction device, including a mounting base; a slidably connected limiting seat is installed inside the mounting base, the bottom end of the limiting seat is elastically connected to the inner bottom wall of the mounting base through a push-out spring, and a push-out groove is provided on the top of the mounting base.

[0007] The limiting seat is provided with a limiting mechanism, which includes a limiting groove formed in the limiting seat, a sliding block installed in the limiting groove, a blocking block fixedly connected to the inner side wall of the limiting groove, one end of the sliding block being elastically connected to one side of the blocking block via a limiting spring, and a first conical block fixedly connected to the other end of the sliding block. The other end of the first conical block extends out of a groove formed on one side of the limiting seat and communicates with the outside. A drive sleeve rod rotatably connected to the inner side wall of the limiting groove is installed, and a gear fixedly connected to the outer circumference of the drive sleeve rod is installed. A drive plate fixedly connected to the side of the sliding block near the spring is installed, and a rack fixedly connected to the side of the drive plate near the gear is installed. The rack meshes with the gear. A through hole is formed at the top of the limiting seat, communicating with the limiting groove. A transmission rod slidably connected to the through hole is installed in the through hole, and a second conical block fixedly connected to the top of the transmission rod extends out of the through hole. The drive sleeve rod is sleeved on the outer wall of the transmission rod.

[0008] Preferably, reset blocks are fixedly installed on both sides of the limiting seat, and a reset assembly is provided on the mounting base. The reset assembly includes a mounting bracket fixedly installed on the top of the mounting base, a cylinder fixedly connected to the inner top wall of the mounting bracket, and a pressing plate fixedly connected to the output end of the cylinder.

[0009] Preferably, the limiting mechanism is provided in two sets, and the two sets of limiting mechanisms are distributed along the direction of vehicle travel, and the two sets of limiting mechanisms are symmetrical to each other.

[0010] Preferably, the drive sleeve has a threaded through groove, and the drive sleeve is threadedly engaged with the transmission rod.

[0011] Preferably, baffles are fixedly installed on both sides of the mounting base, and a corrosion-resistant layer is provided on the outer surface of the mounting base.

[0012] Preferably, the first conical block overlaps with the inner top wall of the mounting groove, and buffer layers are provided on both sides of the limiting seat.

[0013] The advantages of this invention are:

[0014] 1. This invention, through the setting of a limiting mechanism, when the front wheel of the vehicle passes over the second conical block, the front wheel applies pressure to the second conical block, and then the second conical block drives the transmission rod to move down and retract into the through hole. The drive sleeve is threadedly engaged with the transmission rod, and the downward movement of the transmission rod drives the drive sleeve to rotate. The drive sleeve drives the gear to rotate, and the gear meshes with the rack. The rack drives the drive plate to move, and the drive plate drives the sliding plate to move backward. The sliding plate drives the first conical block to retract into the limiting groove until the first conical block is completely retracted into the limiting groove. Then the pressure on the limiting seat disappears. At this time, under the strong elastic force of the ejector spring, the limiting seat is ejected and pushed out of the limiting groove, thus isolating the front and rear wheels of the car and making the car unable to move.

[0015] 2. This invention, through the setting of a reset component, in conjunction with a reset block, can press the limit seat back into the mounting base. Specifically, when the toll station staff finishes collecting tolls, they press the control button to start the cylinder. The cylinder drives the pressing plate to move downwards, and the pressing plate applies pressure to the reset block. Then, the pressing plate, through the reset block, drives the limit seat to apply pressure, causing the limit seat to move downwards. During the downward movement of the limit seat, the first conical block receives pressure and retracts into the limiting groove. When the limit seat is fully reset into the mounting base, under the action of the limiting spring, the first conical block pops out and resets, limiting the limit seat. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figures 1-6 As shown, a device for preventing vehicles from breaking through toll gates at highway toll stations includes a mounting base 1; a slidably connected limiting seat 2 is installed inside the mounting base 1, the bottom end of the limiting seat 2 is elastically connected to the inner bottom wall of the mounting base 1 through an ejection spring 3, and an ejection groove 4 is provided on the top of the mounting base 1.

[0028] The limiting seat 2 is provided with a limiting mechanism 5, which includes a limiting groove 512 formed within the limiting seat 2. A sliding block 51 is slidably connected within the limiting groove 512. A blocking block 52 is fixedly connected to the inner wall of the limiting groove 512. One end of the sliding block 51 is elastically connected to one side of the blocking block 52 via a limiting spring 53. The other end of the sliding block 51 is fixedly connected to a first conical block 54. The other end of the first conical block 54 extends out of a groove formed on one side of the limiting seat 2 and communicates with the outside. A drive sleeve 55 is rotatably connected to the inner wall of the limiting groove 512. A gear 56 is fixedly connected to the outer circumference of the drive sleeve 55. A drive plate 57 is fixedly connected to the side of the sliding block 51 near the spring. A rack 58 is fixedly connected to the side of the drive plate 57 near the gear 56. The rack 58 meshes with the gear 56. A through hole 59 is opened at the top of the limiting seat 2. The through hole 59 communicates with the limiting groove 512. A transmission rod 510 is slidably connected in the through hole 59. The top end of the transmission rod 510 extends out of the through hole 59 and is fixedly connected to a second conical block 511. The drive sleeve 55 is sleeved on the outer wall of the transmission rod 510.When in operation, deploying such spiked defensive devices at highway tollbooth exits can injure unsuspecting pedestrians. Furthermore, after a vehicle attempts to pass through the tollbooth, a punctured tire could cause loss of control, making the extent of injury to the driver unpredictable. Therefore, this device is used. Specifically, a pit compatible with the mounting base 1 is pre-dug at the tollbooth, and the mounting base 1 is fixed within it, with the second cone block 511 facing the direction of oncoming traffic. Through the limiting mechanism 5, when the front wheels of the vehicle pass over the second cone block 511, the front wheels apply pressure to the second cone block 511. This causes the second cone block 511 to move the transmission rod 510 downwards and retract into the through hole 59. The drive sleeve 55 is threadedly engaged with the transmission rod 510. As the transmission rod 510 moves downwards, the drive sleeve 55 rotates, which in turn drives the gear 56 to rotate. The gear 56 meshes with the rack 58. Then, gear 56 drives drive plate 57 to move via rack 58, and drive plate 57 drives sliding plate to move backward. Sliding plate drives first conical block 54 to retract into limiting groove 512. At the same time, sliding plate applies pressure to spring until first conical block 54 is completely retracted into limiting groove 512. Then the pressure on limiting seat 2 disappears. At this time, under the strong elastic force of ejector spring 3, limiting seat 2 is pushed out and out of limiting groove 512, isolating the front and rear wheels of the car, making the car unable to move unless the toll station staff confirms payment and controls limiting seat 2 to move down, releasing the limitation on the car. The elastic force of ejector spring 3 is greater than that of limiting spring 53, thus solving the problem that setting up such spiked defensive devices at highway toll station exits can cause injury to unsuspecting pedestrians, and after a toll-breaking incident, the vehicle may lose control due to a punctured tire, making the degree of injury to the driver unpredictable.

[0029] Both sides of the limiting seat 2 are fixedly installed with reset blocks 6. The mounting base 1 is provided with a reset assembly 7. The reset assembly 7 includes a mounting bracket 71 fixedly installed on the top of the mounting base 1. A cylinder 72 is fixedly connected to the inner top wall of the mounting bracket 71. A pressing plate 73 is fixedly connected to the output end of the cylinder 72. During operation, by setting up the reset assembly 7 and using it in conjunction with the reset blocks 6, the limiting seat 2 can be pressed back into the mounting base 1. Specifically, this is done after the toll station staff has completed collecting the toll. Pressing the control button activates cylinder 72, which in turn moves the pressing plate 73 downward. The pressing plate 73 applies pressure to the reset block 6, which in turn applies pressure to the limit seat 2 via the reset block 6, causing the limit seat 2 to move downward. As the limit seat 2 moves downward, the first conical block 54 receives pressure and retracts into the limit groove 512. When the limit seat 2 is fully reset in the mounting base 1, the first conical block 54 pops out and resets under the action of the limit spring 53, thus limiting the limit seat 2.

[0030] The limiting mechanism 5 is provided in two sets, and the two sets of limiting mechanisms 5 are distributed along the direction of vehicle travel, and the two sets of limiting mechanisms 5 are symmetrical to each other; when working, the conical surface of the first conical block 54 faces the direction of vehicle travel, and the first conical block 54 is in a parallel position with the vehicle wheel.

[0031] The drive sleeve 55 has a threaded through groove, and the drive sleeve 55 is threadedly engaged with the transmission rod 510. During operation, the drive sleeve 55 and the transmission rod 510 are threadedly engaged with each other, and the drive sleeve 55 rotates as the transmission rod 510 moves upward.

[0032] Both sides of the mounting base 1 are fixedly installed with baffles 8, and the outer surface of the mounting base 1 is provided with a corrosion-resistant layer. During operation, the baffles 8 are used in conjunction with the mounting base to form complete protection. At the same time, the corrosion-resistant layer of the mounting base 1 enhances the service life of the mounting base 1 and reduces the service life of the mounting base 1 under the ground.

[0033] The first conical block 54 overlaps with the inner top wall of the mounting groove, and buffer layers are provided on both sides of the limiting seat 2; during operation, the impact force is reduced during vehicle collision by providing buffer layers on both sides of the limiting seat 2.

[0034] Example 2

[0035] Please see Figure 7 As shown in the first embodiment, as another implementation of the present invention, warning plates are provided on both sides of the mounting bracket 71, and warning reflective strips are provided on the warning plates. During operation, the warning plates and the warning reflective strips make it easy for the vehicle owner to see the mounting bracket 71 in rainy or inclement weather, thus avoiding damage to the mounting bracket 71 caused by collision.

[0036] Working principle: A pit matching the mounting base 1 is pre-dug at the toll station, and the mounting base 1 is fixedly installed therein, with the cone of the second cone 511 facing the direction of the approaching vehicle. Through the setting of the limiting mechanism 5, when the front wheel of the vehicle passes over the second cone 511, the front wheel applies pressure to the second cone 511, causing the second cone 511 to drive the transmission rod 510 downwards and retract into the through hole 59. The drive sleeve 55 is threadedly engaged with the transmission rod 510, and as the transmission rod 510 moves downwards, it drives the drive sleeve 55 to rotate. Then, the drive rod 55 drives the gear 56 to rotate, and the gear 56 meshes with the rack 58. The gear 56 then drives the drive plate 57 to move via the rack 58. The drive plate 57 then drives the sliding plate to move backward, causing the first conical block 54 to retract into the limiting groove 512. Simultaneously, the sliding plate applies pressure to the spring until the first conical block 54 is completely retracted into the limiting groove 512. Then, the pressure on the limiting seat 2 disappears. At this point, under the strong elastic force of the ejector spring 3, the limiting seat 2 is ejected and pushed out of the limiting groove 512, thus allowing the front and rear wheels of the car to... The barrier prevents the car from moving unless the tollbooth staff confirms payment and then lowers the limit seat 2 to release the restriction. The force of the push-out spring 3 is greater than the force of the limit spring 53. This solves the problem that installing such spiked defensive devices at highway tollbooth exits can injure unsuspecting pedestrians, and that after a tollbooth attempt, a punctured tire could cause the vehicle to lose control, making the extent of injury to the driver unpredictable. The reset component 7, used in conjunction with the reset block 6, can press the limit seat 2 back into the mounting base 1. Specifically, after the toll station staff completes the toll collection, they press the control button to activate cylinder 72. Cylinder 72 drives the pressing plate 73 to move downward, and the pressing plate 73 applies pressure to the reset block 6. Then, the pressing plate 73, through the reset block 6, drives the limit seat 2 to apply pressure, causing the limit seat 2 to move downward. During the downward movement of the limit seat 2, the first conical block 54 receives pressure and retracts into the limit groove 512. When the limit seat 2 is fully reset in the mounting base 1, under the action of the limit spring 53, the first conical block 54 pops out and resets, limiting the limit seat 2.
