Description

Technical Field

[0001] This invention relates to the field of track gate technology, and more particularly to a three-fold lever track gate. Background Technology

[0002] A level crossing barrier is an automatic closing device used at railway crossings. It uses a mechanical structure and electronic control system to automatically raise and lower the crossing barriers to ensure the safety of railway and road traffic. This device is typically installed at railway and road crossings. When a train approaches, the barriers automatically lower to prevent vehicles and pedestrians from entering the railway tracks, and only rise again after the train has passed.

[0003] In existing gate operating mechanisms, the first barrier is horizontally positioned on the housing. When the arm needs to be folded, the operator presses a switch. This switch is a single-pole double-throw switch with three working positions, controlling the motor's forward, reverse, and stop directions. When the switch controls the motor to rotate forward, the motor drives the gear shaft. Since the gear shaft and bevel gear form a bevel gear transmission, which transmits motion and power between two intersecting shafts, rotation along the X-axis of the gear shaft plane enables rotation along the Y-axis of the bevel gear plane. Because the bevel gear is fixedly connected to the shaft, and the shaft is fixedly connected to the second barrier, the rotation of the bevel gear is equivalent to the rotation of the shaft. The rotation of the second barrier allows for its rotation. When the second barrier reaches the desired position, the switch can be moved to the stop position or the reverse position to reset the second barrier. When the extension or retraction of the barrier needs to be adjusted, the reversing valve, being a three-position four-way valve, allows for the extension and retraction of the hydraulic cylinder push rod. Since the push rod is fixedly connected to the third barrier, its extension and retraction cause the third barrier to extend and retract within the second barrier. However, existing barrier gates, due to their design involving multiple mechanical components and linkages, increase system complexity and affect system durability.

[0004] Therefore, it is necessary to provide a new three-fold bar track gate to solve the above-mentioned technical problems. Summary of the Invention

[0015] Compared with related technologies, the three-fold bar track closing machine provided by the present invention has the following beneficial effects:

Furthermore, the three-fold design makes the movement path of the arms shorter, allowing for faster opening and closing actions and improving vehicle traffic efficiency.

[0017] This invention utilizes a barrier gate device and an oiling assembly. When a vehicle exits the parking lot, the stepper motor inside the barrier gate is activated. The stepper motor drives several second gears to rotate via a drive ring. As the second gears rotate, they rotate along the internal gears, simultaneously driving the first gear to rotate. This, in turn, moves the rotating rod on the first gear. The rotating rod, in turn, moves the first barrier arm, which in turn moves the drive rod. Simultaneously, the drive rod, through its own first coupling, moves the second barrier arm. The movement of the second barrier arm, through two connecting rods and a fixed rod on the first coupling, moves the second coupling, thus lifting the barrier arm of the barrier gate and retracting it into the receiving slot on the barrier gate. Simultaneously, the oiling assembly lubricates the drive assembly. This device reduces system complexity, minimizes the impact on system durability, reduces mechanical shock, and improves system reliability and lifespan. Attached Figure Description

The storage cover plate 12 is fixedly connected to the end of the protective plate 15 away from the front cover plate 11, and a storage groove for storage is opened on one side wall of the storage cover plate 12. The barrier gate device 2 includes a rotating rod 21, a first barrier rod 22, and a second barrier rod 23. The barrier arm 23 and the third barrier arm 24 are connected to a drive assembly 4 at one end of a rotating rod 21, and a connecting rod 25 is fixedly connected to the end of the rotating rod 21 away from the drive assembly 4. The first barrier arm 22 is fixedly connected to the end of the connecting rod 25 away from the rotating rod 21, and a coupling assembly 3 is movably connected to the end of the first barrier arm 22 away from the connecting rod 25. The second barrier arm 23 is fixedly connected to the end of the coupling assembly 3 away from the first barrier arm 22. The third barrier arm 24 is movably connected to the end of the second barrier arm 23 away from the first barrier arm 22 through the coupling assembly 3. A warning sign 7 is fixedly connected to the second barrier arm 23 by bolts.

[0032] The coupling assembly 3 includes a first coupling 31 and two connecting rods 32. One end of the first coupling 31 is movably connected to the end of the first gate rod 22 away from the connecting rod 25, and the end of the first coupling 31 away from the first gate rod 22 is movably connected to one end of the second gate rod 23. The bottom of the first coupling 31 is movably connected to a drive rod 33 via a fixed column. The end of the drive rod 33 away from the first coupling 31 is movably connected to one end of the housing 1 via a fixed frame. One end of the two connecting rods 32 is rotatably connected to the top of the first coupling 31 via a rotating shaft 44, and the end of the two connecting rods 32 away from the first coupling 31 is fixedly connected to a fixed rod 34. The end of the fixed rod 34 away from the connecting rods 32 is rotatably connected to a second coupling 35. One end of the second coupling 35 is rotatably connected to the second gate rod 23, and the end of the second coupling 35 away from the second gate rod 23 is movably connected to a third gate rod 24.

[0033] The drive assembly 4 includes an internal gear 41, a first gear 42, and a stepper motor 43. The internal gear 41 is fixedly connected to the end of the rotating rod 21 away from the connecting rod 25, and a plurality of second gears 46 are meshed on one side of the internal gear 41. Each of the plurality of second gears 46 is rotatably connected to a rotating shaft 44. One end of the rotating shaft 44 is rotatably connected to the inner wall of the outer casing 1, and a fixing ring 45 is rotatably connected to the end of the rotating shaft 44 away from the outer casing 1. The first gear 42 is meshed between the plurality of second gears 46. The stepper motor 43 is fixedly connected to the top of the support plate provided inside the outer casing 1, and the output end of the stepper motor 43 is fixedly connected to one end of the fixing ring 45.

[0034] It should be noted that the camera 13 installed on the front cover 11 is mainly used for vehicle recognition and management. This camera 13 usually has high definition, fast recognition and stable performance to ensure the smooth and safe entry and exit of vehicles. At the same time, the camera 13 can monitor the situation of vehicles entering and exiting the passage in real time, including the vehicle's speed and direction. This helps managers to discover and deal with abnormal situations in a timely manner, such as vehicles driving in the wrong direction or speeding.

[0035] The first coupling 31 and the second coupling 35 are key structures for folding between the first gate arm 22, the second gate arm 23 and the third gate arm 24, respectively. The warning sign 7 on the second gate arm 23 and the warning light 8 on the protective frame 69 are also important components. The warning sign 7 is usually placed in a conspicuous position on the second gate arm 23 to ensure that passing vehicles and pedestrians can see it clearly from a distance. The warning sign 7 usually has words such as "One vehicle, one gate", "Do not follow", and "Speed ​​limit XX" printed on it to remind vehicles to pass in order and avoid the safety hazards caused by following other vehicles. The warning light 8 is set on the protective frame 69 mainly to enhance the visual warning effect for passing vehicles and pedestrians, especially at night or in low light conditions, so as to attract people's attention.

[0036] When a vehicle leaves the parking lot, the stepper motor 43 inside the gate barrier is activated. The stepper motor 43 drives several second gears 46 to rotate via a drive ring. As the second gears 46 rotate, they rotate along the internal gear 41, simultaneously driving the first gear 42 to rotate. This causes the rotating rod 21 on the first gear 42 to move. As the rotating rod 21 moves, it drives the first gate lever 22 to move, which in turn drives the drive rod 33 to move. Simultaneously, the drive rod 33 moves, driving the second gate lever 23 to move via the first coupling 31. As the second gate lever 23 moves, it drives the second coupling 35 to move via the two connecting rods and the fixed rod 34 on the first coupling 31. This lifts the gate lever of the gate barrier and retracts it into the storage slot on the gate barrier.

One end of the compression spring 531 is fixedly connected to one end of the support frame, and the end of the compression spring 531 away from the support frame is fixedly connected to one end of the U-shaped moving plate 58.

[0039] In use, the servo motor 534 is started first. The servo motor 534 drives the half gear 532 to rotate. While the half gear 532 is rotating, it drives the rack 533 to move away from the U-shaped moving plate 58. When the gear on the half gear 532 disengages from the rack 533, the rack 533 moves towards the U-shaped moving plate 58 under the action of the compression spring 531. It also drives the U-shaped moving plate 58, push rod 57 and piston 56 to move into the fixed tube 55 through the transmission rod 535. The lubricating oil inside the conversion box 52 is sprayed out from the oil outlet pipe 54 and the oil nozzle to lubricate the drive component 4. Example 2
