Description

Technical Field

[0001] The invention relates to the technical field of barrier gate machines, and in particular to a clutch transmission device for an electric barrier gate machine in a garage. Background Art

[0002] A barrier gate is a means of protecting pedestrians and other vehicles when a highway intersects with other tracks. In order to collect fees from passing vehicles or manage vehicles entering and leaving parking lots and communities, barrier gates are generally installed at the vehicle entrances and exits of toll stations, parking lots, communities, etc.

[0003] Most barrier gate machines are equipped with a clutch transmission device on the power output shaft, so that when a power outage or an emergency occurs and the power needs to be cut off urgently, the gate rod can be pushed up manually. However, after long-term use of the barrier gate machine, some barrier gate machines are installed outdoors, and the rotating connection of the power output shaft is easily blocked, affecting the smoothness of rotation. The gate rod is prone to abnormal noise during the lifting and lowering process. In addition, when the blockage is serious, the resistance of the rotating connection of the power output shaft is greater than the friction force of the clutch, which can easily cause the gate rod to be unable to be automatically lifted, affecting the service life of the barrier gate machine.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] like Figure 1-Figure 9As shown, the clutch transmission device for the electric barrier gate of the garage comprises a housing 1, a barrier gate 2, an upper end cover 3 arranged at the upper end of the housing 1 and a front end cover 4 arranged at the front side of the housing 1, a power output shaft 6 for driving the barrier gate 2 to rotate is rotatably provided inside the housing 1, a friction wheel 12 is rotatably sleeved on the outer side of the power output shaft 6, two friction plates 21 matching with the friction wheel 12 are symmetrically sleeved on the outer side of the power output shaft 6, and the friction wheel 12 is in the shape of an incomplete gear, a fixing plate 5 is provided inside the housing 1, a worm 8 matching with the friction wheel 12 is rotatably provided on the upper end of the fixing plate 5, and a worm 8 matching with the friction wheel 12 is rotatably provided on the lower end of the fixing plate 5 The motor 9 for driving the worm 8 to rotate, the housing 1 is provided with a controller 10, the power output shaft 6 is rotatably connected to the side wall of the housing 1 through the bearing 7, the surface of the bearing 7 is provided with an oiling nozzle 11 and is located inside the housing 1, and the housing 1 is provided with an oiling assembly for matching the oiling nozzle 11. When in use, the motor 9 drives the worm 8 to rotate, and the rotation of the worm 8 drives the friction wheel 12 to rotate. Relying on the friction between the two friction plates 21 and the friction wheel 12, the friction wheel 12 rotates to rotate the power output shaft 6, thereby driving the gate 2 to deflect, so that the gate 2 is opened or closed;

[0037] The oil filling assembly includes an oil tank 16 fixedly arranged inside the casing 1 and a conversion box 17 fixedly arranged at the upper end of the oil tank 16. The lower end of the conversion box 17 is provided with an oil extraction pipe 34 matched with the oil tank 16. A first oil delivery pipe 14 is provided on one side of the conversion box 17. The input ends of the first oil delivery pipe 14 and the oil extraction pipe 34 are both provided with a hydraulic one-way valve 35. The output end of the first oil delivery pipe 14 is connected with the oil filling nozzle 11 through the second oil delivery pipe 15. A fixed pipe 28 is provided on one side of the conversion box 17. A piston 29 is slidably provided inside the fixed pipe 28. A piston rod 31 is provided on one side of the piston 29 to drive the piston 29 to move. A transmission member for driving the piston rod 31 to move is provided inside the casing 1. When the bearing 7 needs to be lubricated during use, the staff pulls the piston rod 31 to drive the piston 29 to move, and the piston 29 moves inside the fixed tube 28, so that the inside of the conversion box 17 is in a negative pressure state. At this time, the lubricating oil inside the oil tank 16 is pumped into the conversion box 17 through the oil extraction pipe 34, and then the staff pushes the piston rod 31 to move in the opposite direction, squeezing the lubricating oil inside the conversion box 17 to be discharged outward through the first oil pipe 14, and injected into the oiling nozzle 11 along the second oil pipe 15, so as to achieve the effect of lubricating the bearing 7 and ensure the smooth rotation of the power output shaft 6.

[0038] Further, the transmission member includes a driven shaft 24 rotatably arranged inside the housing 1 and a collar 26 slidably sleeved on the outside of the driven shaft 24, a spring is provided at the rotation connection of the driven shaft 24, a spiral groove 39 is provided on the outer surface of the driven shaft 24, a convex block 33 matching the spiral groove 39 is fixedly provided on the inner side of the collar 26, a connecting seat 32 is fixedly provided on the outer surface of the collar 26, a U-shaped moving plate 30 is provided at the end of the piston rod 31 away from the piston 29, the connecting seat 32 is located on the inner side of the U-shaped moving plate 30 and is slidably connected to the piston rod 31, A ratchet 25 matching the friction wheel 12 is sleeved on the outer side of the moving shaft 24, a spring telescopic rod 27 is provided on the upper end of the fixed plate 5, a lifting plate 36 is provided on the telescopic end of the spring telescopic rod 27, a tooth block 37 matching the ratchet 25 is provided on the surface of the lifting plate 36, and a pressure block 38 matching the U-shaped moving plate 30 is provided on one side of the lifting plate 36. When in use, when the worm 8 rotates to drive the friction wheel 12 to rotate counterclockwise, that is, when the gate 2 is turned over and lifted, the friction wheel 12 is not meshed with the ratchet 25 in the initial state (refer to the attached manual). Figure 5), as the friction wheel 12 rotates, the friction wheel 12 gradually meshes with the ratchet 25, driving the ratchet 25 to rotate. Since the barrier 2 is lifted to a specified height each time, that is, the friction wheel 12 deflects at a certain angle each time, the ratchet 25 will only deflect 1-2 teeth during the barrier 2 lifting process. Then, when the worm 8 rotates to drive the friction wheel 12 to rotate clockwise, that is, when the barrier 2 is driven to flip and fall, the reverse rotation of the ratchet 25 is constrained by the tooth block 37 and cannot be reversed. The friction wheel 12 will not drive the ratchet 25 to rotate when it rotates clockwise. From the above analysis, it can be seen that each time the barrier 2 is lifted, the ratchet 25 will be deflected to a certain extent, that is, the driven shaft 2 4 is rotated, and the mainspring is subjected to force during the rotation of the driven shaft 24. The rotation of the driven shaft 24 causes the ring 26 to move under the cooperation of the spiral groove 39 and the protrusion 33. The movement of the ring 26 drives the connecting seat 32 to slide along the outer side of the piston rod 31. When the connecting seat 32 slides at the end of the piston rod 31, it abuts against one side of the inner wall of the U-shaped moving plate 30. The connecting seat 32 continues to move to drive the U-shaped moving plate 30 to move. The movement of the U-shaped moving plate 30 drives the piston rod 31 to move. The movement of the piston rod 31 pulls the piston 29 to move, so that the inside of the conversion box 17 is in a negative pressure state, that is, the lubricating oil in the oil tank 16 is sucked into the inside of the conversion box 17 through the oil extraction pipe 34. As the U-shaped moving plate 30 moves, the oil in the oil tank 16 is sucked into the inside of the conversion box 17. The movement of the U-shaped movable plate 30 will cause the pressure block 38 to move downward. The downward movement of the pressure block 38 drives the lifting plate 36 and the tooth block 37 to move downward. The spring telescopic rod 27 is compressed, causing the tooth block 37 to disengage from the ratchet 25. At this time, under the reset action of the spring, the driven shaft 24 rotates in the opposite direction. The driven shaft 24 rotates in the opposite direction. Under the cooperation of the spiral groove 39 and the protrusion 33, the collar 26 moves in the opposite direction. The reverse movement of the collar 26 initially drives the connecting seat 32 to slide along the outer side of the piston rod 31. When the connecting seat 32 is pressed against the other side of the inner wall of the U-shaped movable plate 30, the connecting seat 32 continues to move, which drives the U-shaped movable plate 30 to move. The movement of the U-shaped movable plate 30 drives the movable The plug rod 31 moves, and the piston rod 31 moves to push the piston 29, that is, the lubricating oil inside the conversion box 17 is squeezed to be discharged outward through the first oil pipe 14, and is injected into the oil filling nozzle 11 along the second oil pipe 15. In this process, the U-shaped movable plate 30 will gradually release the squeezing of the pressure block 38, and under the action of the resetting of the spring telescopic rod 27, the lifting plate 36 and the tooth block 37 move upward and reset, that is, the tooth block 37 cooperates with the ratchet 25 again, so as to realize the effect of restraining the rotation of the ratchet 25. In summary, through several lifting and lowering of the gate 2, the effect of automatically replenishing the lubricating oil to the bearing 7 is achieved, which effectively ensures the lubricity of the bearing 7 and ensures the smoothness of the lifting and lowering of the gate 2.

[0039] Furthermore, the two friction plates 21 are respectively slidably connected to the power output shaft 6 and have mounting grooves 22 on opposite sides. A mounting plate 23 is arranged in the mounting groove 22. The mounting plate 23 is U-shaped and fixedly connected to the mounting groove 22 by bolts. A slide groove 20 for the mounting plate 23 to pass through is arranged on the outer surface of the power output shaft 6. The end of the power output shaft 6 away from the barrier 2 is hollow and has an electromagnet 18 fixedly arranged inside for adsorbing the mounting plate 23 so that the friction plate 21 fits tightly against the friction wheel 12. The electromagnet 18 is electrically connected to the controller 10 through a wire 19. When in use, when the power is off, the electromagnet 18 is powered off to release the adsorption of the mounting plate 23. At this time, the friction plate 21 is not tightly fitted against the friction wheel 12, that is, the friction resistance between the friction wheel 12 is small. The staff can manually flip the barrier 2 upward and lift it up. The upward flipping of the barrier 2 drives the power output shaft 6 to idle, and the operation process is relatively labor-saving.

[0040] Furthermore, a support plate 13 is fixed to the upper end of the fixed plate 5, and one end of the power output shaft 6 and the driven shaft 24 are respectively rotatably connected to the support plate 13 to prevent the end portions of the power output shaft 6 and the driven shaft 24 from jumping during rotation, thereby effectively ensuring the stability of the power output shaft 6 and the driven shaft 24 during rotation.

[0041] Furthermore, the first oil pipeline 14 is a hose and the second oil pipeline 15 is a hard pipe to avoid transportation through the hose alone. The hose is easy to get tangled and knotted when laid for a long time. When in use, the first oil pipeline 14 and the second oil pipeline 15 can be connected to each other and can be set to multiple groups to achieve oiling and lubrication of multiple bearings 7 respectively, such as the bearings at the rotating connections at both ends of the driven shaft 24 (not shown in the drawings).

[0042] Furthermore, the pressure value of the hydraulic one-way valve 35 is greater than the elastic force value of the spring telescopic rod 27, and the pressure value of the hydraulic one-way valve 35 is less than the elastic force value of the spring. During the oil injection process, when the U-shaped movable plate 30 squeezes the pressure block 38, the elastic force of the spring telescopic rod 27 is not sufficient to push the U-shaped movable plate 30 to move in the opposite direction, so that the piston 29 moves in the opposite direction to push the lubricating oil in the conversion box 17 from the hydraulic one-way valve 35 to the second oil pipe 15. During the process of the spring driving the driven shaft 24 to move in the opposite direction, the resetting effect of the spring is sufficient to push the U-shaped movable plate 30 to move in the opposite direction, so that the piston 29 moves in the opposite direction to push the lubricating oil in the conversion box 17 from the hydraulic one-way valve 35 to the second oil pipe 15.

[0043] Embodiment 2:

[0044] like Fig.10As shown, further, an electromagnetic block 41 that cooperates with the lifting plate 36 is provided on the outer side of the spring telescopic rod 27, and a touch-pressure switch 40 that cooperates with the outer side of the U-shaped movable plate 30 is provided on the outer side of the fixed tube 28. The touch-pressure switch 40 is electrically connected to the electromagnetic block 41, and the touch-pressure switch 40 and the electromagnetic block 41 are respectively electrically connected to the controller 10. When in use, when the spring telescopic rod 27 is compressed, the lifting plate 36 and the electromagnetic block 41 are adsorbed, so that the tooth block 37 remains disengaged from the ratchet 25, and then as the U-shaped movable plate 30 drives the piston rod 31 to move to push oil, after the oil pushing is completed, the U-shaped movable plate 30 will squeeze the touch-pressure switch 40, so that the electromagnetic block 41 is powered off, and at this time the spring telescopic rod 27 is reset to drive the tooth block 37 to reset, so that the tooth block 37 remains engaged with the ratchet 25.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
