Description

Technical Field

[0001] This utility model relates to the field of barrier gate technology, and in particular to an automatic barrier gate for entrances and exits. Background Technology

[0002] As a commonly used device for road traffic management and access control, the barrier gate is widely used in residential communities, commercial plazas, industrial parks, government agencies, and public parking lots. With the acceleration of urbanization and the continuous growth of motor vehicle ownership, higher requirements have been placed on the intelligence and automation of vehicle access management.

[0003] Traditional barrier gates typically use wooden or metal booms to block vehicles from entering or exiting. They are usually controlled by hydraulic levers to raise or retract the boom. However, this type of rigid boom structure presents the following problems in practical use:

[0004] 1. Traditional gate arms, when subjected to strong forces such as forced entry or strong winds during use, may break and be damaged due to their inability to deform, affecting their subsequent use.

[0005] Second, the traditional gate opening and closing operation of flipping or folding is extremely inefficient and can easily cause traffic congestion at intersections.

[0006] Therefore, how to provide an automatic gate at entrances and exits is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide an automatic gate at entrances and exits. This invention can effectively improve vehicle traffic efficiency, adapt to strong stress conditions, and achieve a self-cleaning effect.

[0008] An automatic gate for entrance and exit according to an embodiment of the present utility model includes two sets of gate posts arranged opposite each other. The feature is that the two sets of gate posts have movable openings on their opposite side surfaces. A gate bar assembly is arranged between the two sets of gate posts. The gate bar assembly includes an elastic cloth belt, a winding roller and a winding motor. The two ends of the elastic cloth belt are respectively wound around the surface of the winding roller. The winding roller is rotatably arranged in the mounting frame by the winding motor.

[0009] A tilting mechanism is installed inside the gate column on the side near the mounting frame. The tilting mechanism includes a motor and tilting teeth. When the motor is started, it drives the mounting frame to move up and down inside the gate column and tilts the gate column at both ends.

[0010] The output shaft of the winding motor has a mating tooth through a single tooth meshing. A mating transmission mechanism is provided at one end of the top of the gate. The mating transmission mechanism includes a conveyor belt assembly and a movable belt assembly. The conveyor belt assembly and the movable belt assembly are connected by transmission. The movable belt assembly is connected to the mating tooth through a displacement tooth. The conveyor belt assembly drives the cleaning roller to rotate at the top of one side of the gate.

[0011] Furthermore, the motor output shaft passes through the transmission pair via a lead screw thread, and one side of the transmission pair slides inside the brake column via a stabilizing slide rail. The transmission pair is movably passed through the upper part of the mounting bracket via a shaft.

[0012] Furthermore, a vertical plate frame is installed inside the gate column near the shaft position of the mounting frame and the transmission pair. The upper and lower surfaces of the vertical plate frame are respectively provided with toothed rods, which mesh and align with the flipping teeth. The flipping teeth are fixed on the surface of the shaft that is movably connected to the mounting frame and the transmission pair.

[0013] Furthermore, the movable belt assembly also includes a first pulley, a second pulley, a third pulley, and a belt. The first pulley is elastically connected inside the gate post via a spring seat. The third pulley is fixed to a pulley on one side of the transmission belt assembly. The third pulley is limited to rotate inside the gate post by a movable frame. A belt is fitted onto the surfaces of the first pulley, the second pulley, and the third pulley.

[0014] Furthermore, one side of the second pulley is fixedly connected to the displacement tooth, and the shaft of the second pulley is rotatably mounted on one side of the stabilizer via a shaft pin. The stabilizer moves laterally inside the gate column via an electric cylinder.

[0015] Furthermore, the side of the conveyor belt assembly away from the movable belt assembly is connected to the cleaning roller via a pulley, and the cleaning roller is limited to rotate above one side surface of the gate column by a support frame.

[0016] Furthermore, when the mounting frame is rotated to a 90-degree position, the mating teeth on the top surface of the mounting frame are aligned with the displacement teeth and located in the same vertical direction.

[0017] The beneficial effects of this utility model are:

[0018] This utility model, through its tilting mechanism, allows the motor to drive the lead screw to rotate, causing the transmission pair to move the entire mounting frame up and down. When the mounting frame drives the tilting teeth to engage with the gear, the meshing effect causes the mounting frame to rotate the elastic cloth belt 90 degrees and adhere to the ground, preventing it from obstructing the normal entry and exit of wheels. With two sets of gate posts corresponding to two sets of mounting frames, the effect of pulling a single set of elastic cloth belt to move up and down between the two sets of gate posts can effectively improve the efficiency of opening and closing the roadway. Compared with the traditional hydraulic transmission type with high torque, this device reacts more quickly, and the actual stroke of the elastic cloth belt is shorter, which can effectively prevent the occurrence of problems such as blockage at the intersection due to slow opening and closing of the gate.

[0019] This utility model incorporates an elastic fabric belt and a winding roller. The winding roller is driven by a winding motor to wind the elastic fabric belt, ensuring that the elastic fabric belt automatically winds up and down on the surface of the winding roller under stress conditions. This makes it more suitable for use under strong stress conditions and prevents damage to traditional gate arms from strong stress during situations such as gate breaches or strong winds.

[0020] This invention features a docking transmission mechanism installed inside the gate column. The first pulley moves elastically via a spring seat, ensuring the belt tension on the surface of the second pulley. The second pulley can then be moved by the stabilizer, causing the displacement teeth on one side to engage with the docking teeth on the surface of the mounting frame. In this case, after the winding motor starts, it can not only drive the elastic belt to wind around the roller surface, but also the third pulley can drive the cleaning roller to rotate through the transmission belt assembly to clean the surface of the elastic belt, achieving a self-cleaning effect for the elastic belt.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] refer to Figures 1-6 The system includes two sets of opposing gate posts 1, with movable openings 2 on the opposite sides of the gate posts 1. A gate bar assembly 3 is provided between the two sets of gate posts 1. The gate bar assembly 3 includes an elastic fabric belt 31, a winding roller 32, and a take-up motor 33. The two ends of the elastic fabric belt 31 are respectively wound around the surface of the winding roller 32. The winding roller 32 is rotatably mounted in the mounting frame 6 by the take-up motor 33. A tilting mechanism 7 is provided inside the gate post 1 on the side near the mounting frame 6. The tilting mechanism 7 includes a motor 71 and a tilting tooth 74. The motor 71 drives the gate post 1 to tilt. The mounting frame 6 moves up and down inside the gate 1 and flips at both ends of the gate 1; the output shaft of the winding motor 33 is connected to the docking tooth 54 through a single tooth; a docking transmission mechanism 5 is provided at one end of the top of the gate 1; the docking transmission mechanism 5 includes a transmission belt assembly 51 and a movable belt assembly 52; the transmission belt assembly 51 and the movable belt assembly 52 are connected by transmission; the movable belt assembly 52 is connected to the docking tooth 54 through a displacement tooth 53; the transmission belt assembly 51 drives the cleaning roller 4 to rotate at the top of one side of the gate 1.

[0033] In this implementation scheme, the two sets of opposing gate posts 1 can jointly support the elastic fabric belt 31 through the mounting frame 6. After the winding motor 33 at the top of the mounting frame 6 is started, the winding motor 33 drives the winding roller 32 to wind up, while the winding motor 33 inside the other set of gate posts 1 drives the winding roller 32 to unwind. At this time, the elastic fabric belt 31 will be wound to one side under force. After the motor 71 is started, it can drive the mounting frame 6 to move up and down inside the gate post 1. When it moves to the highest and lowest positions, it will drive the mounting frame 6 to flip in one direction. When the mounting frame 6 moves to the lowest position, the flipping effect makes the elastic fabric belt 31 flat with the ground, preventing the elastic fabric belt 31 from obstructing the normal passage of the wheel. Conversely, when it moves to the highest position, the elastic fabric belt 31 will be in contact with the surface of the cleaning roller 4. Under the transmission effect of the docking transmission mechanism 5, the cleaning roller 4 and the elastic fabric belt 31 move synchronously to achieve the purpose of self-cleaning.

[0034] refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 The output shaft of the motor 71 passes through the transmission pair 73 via a lead screw 72. One side of the transmission pair 73 is limited and slidable inside the gate post 1 by a stabilizing slide rail 76. The transmission pair 73 is movably passed through the upper part of the mounting frame 6 via a shaft. A vertical plate frame is provided inside the gate post 1 near the shaft position of the mounting frame 6 and the transmission pair 73. The upper and lower surfaces of the vertical plate frame are respectively provided with a toothed rod 75. The toothed rod 75 meshes and aligns with the flipping tooth 74. The flipping tooth 74 is fixed to the surface of the shaft that movably connects the mounting frame 6 and the transmission pair 73.

[0035] In this embodiment, after the motor 71 starts, it can directly drive the lead screw 72 to rotate inside the gate 1. The transmission pair 73 is threadedly connected to the surface of the lead screw 72, and the transmission pair 73 is restricted by the movement of the stabilizing slide rail 76 on one side. This allows the transmission pair 73 to move up and down inside the gate 1 after the lead screw 72 rotates, thereby causing the mounting frame 6 to move up and down. The shaft on one side of the mounting frame 6 is connected to the transmission pair 73, and the connection position is above one side of the mounting frame 6. This ensures that the overall center of gravity of the mounting frame 6 is below the shaft, which can effectively prevent the mounting frame 6 from moving. The self-reversing phenomenon improves the movement stability of the mounting frame 6. When the transmission pair 73 drives the mounting frame 6 to the highest or lowest position inside the gate 1, the reversing teeth 74 on the shaft of the mounting frame 6 will engage with the toothed bar 75. The continuous movement will cause the mounting frame 6 to rotate 90 degrees on one side of the transmission pair 73 through the meshing effect of the reversing teeth 74 and the toothed bar 75, thereby causing the elastic cloth belt 31 to rotate, so that it is in contact with the cleaning roller 4 or the ground. The former facilitates cleaning, while the latter facilitates the normal passage of the wheels.

[0036] refer to Figure 4 and Figure 5 The movable belt assembly 52 also includes a first pulley 521, a second pulley 522, a third pulley 523, and a belt 524. The first pulley 521 is elastically connected to the inside of the gate post 1 via a spring seat 525. The third pulley 523 is fixed to a pulley on one side of the conveyor belt assembly 51 and is limited to rotate within the gate post 1 by a movable frame. The belt 524 is fitted onto the surfaces of the first pulley 521, the second pulley 522, and the third pulley 523. One side of the second pulley 522 is fixedly connected to a displacement tooth 53, and the shaft of the second pulley 522 is rotatably mounted on one side of a stabilizer 55 via a pin. One side of the stabilizer 55 moves laterally inside the gate post 1 via an actuator 56. The side of the conveyor belt assembly 51 away from the movable belt assembly 52 is connected to the cleaning roller 4 via a pulley. The cleaning roller 4 is limited to rotate above one side surface of the gate post 1 by a support frame.

[0037] In this embodiment, the elastic movement of the first pulley 521 inside the gate 1 via the spring seat 525 allows the belt 524 to undergo local deformation, thereby better adapting to the tensioning operation of the second pulley 522 in the moving state. This allows the second pulley 522 to drive the belt 524 to move in various positions. When the second pulley 522 drives the displacement tooth 53 on one side to mesh with the mating tooth 54 on the surface of the mounting frame 6, this occurs after the mounting frame 6 has been rotated 90 degrees, as will be explained later. At this time, the start of the winding motor 33 will drive the mating tooth 54 to rotate through the single tooth. The mating tooth 54 drives the displacement tooth 53 to rotate, which in turn drives the belt 524 to move through the second pulley 522. The movement of the belt 524 is then transmitted to the surface of the third pulley 523. The rotation of the third pulley 523 will drive the transmission belt assembly 51 to move. One side of the transmission belt assembly 51 is connected to the cleaning roller 4. The rotation of the cleaning roller 4 will perform a brushing operation on the surface of the elastic fabric belt 31 after the rotation is completed.

[0038] refer to Figures 1-6 When the mounting frame 6 is rotated to the 90-degree position, the mating teeth 54 on the top surface of the mounting frame 6 are aligned with the displacement teeth 53 and are located in the same vertical direction.

[0039] In this embodiment, the mounting position of the mating tooth 54 is at the top of the mounting frame 6. After the mounting frame 6 is rotated 90 degrees under force, the spatial position of the mating tooth 54 is just flush with the displacement tooth 53 on one side of the second pulley 522. At this time, the second pulley 522 drives the displacement tooth 53 to move and mesh with the mating tooth 54, thereby completing the transmission operation.

[0040] Working principle: During normal use, the motor 71 starts and drives the lead screw 72 to rotate. The transmission pair 73 is restricted by the stable slide rail 76 and moves downward on the surface of the lead screw 72, which in turn drives the mounting frame 6 to move downward. The inner side of the mounting frame 6 is wrapped with the elastic cloth belt 31 on the surface of the roller 32, so that the movement of the mounting frame 6 will synchronously drive the elastic cloth belt 31 to move downward in the movable opening 2 until it reaches the lowest position of the gate 1. At this time, the flipping tooth 74 on the shaft connecting the mounting frame 6 and the transmission pair 73 will mesh with the single set of toothed rods 75. The meshing effect will cause the mounting frame 6 and the elastic cloth belt 31 to rotate 90 degrees as a whole, so that the elastic cloth belt 31 is exactly flat with the ground. At this time, the vehicle can pass through the two sets of gate 1 normally.

[0041] When the device breaks through the checkpoint, the elastic belt 31 will cause the roller 32 to loosen flexibly. The flexible material of the elastic belt 31 itself has a stronger deformation capacity than the traditional rigid structure, which prevents the elastic belt 31 from being damaged by force.

[0042] When the motor 71 drives the mounting frame 6 and the elastic belt 31 to the highest position inside the gate 1, the flipping effect will cause the mounting frame 6 to drive the docking tooth 54 to be aligned with the displacement tooth 53. At this time, the electric cylinder 56 starts and drives the stabilizing frame 55 to move. The stabilizing frame 55 drives the second pulley 522 and the displacement tooth 53 to move, so that the displacement tooth 53 engages with the docking tooth 54. During this process, the belt 524 is pulled by the force to drive the first pulley 521. The first pulley 521 moves under the elastic connection of the spring seat 525, ensuring the tension effect of the belt 524, the second pulley 522, the first pulley 521 and the third pulley 523. At this time, after the winding motor 33 starts, the docking tooth 54 drives the displacement tooth 53 and the second pulley 522 to rotate. The rotation of the third pulley 523 directly drives the cleaning roller 4 to rotate through the transmission belt assembly 51. At this time, the elastic belt 31 is in contact with the surface of the cleaning roller 4. The rotation effect will cause the cleaning roller 4 to automatically brush the surface of the elastic belt 31.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
