Detailed implementation manner
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1 to 5 , an embodiment of the present invention provides a barrier gate reducer, including: a chassis 1, a motor 2 is installed on the left side inside the chassis 1, and the shaft end of the motor 2 is connected to a machine shaft 3, the shaft end of the machine shaft 3 is connected to a driving bevel gear 4, a driving shaft 5 is installed inside the chassis 1 and on the right side of the motor 2, and a driven bevel gear 6 is sleeved on the right part of the driving shaft 5. The central axes between the driving bevel gear 4 and the driven bevel gear 6 are perpendicular to each other, and the driving bevel gear 4 and the driven bevel gear 6 are meshed with each other. A driving gear 7 is sleeved on the left part of the driving shaft 5, and a driven shaft 8 is installed inside the chassis 1 and on the right side of the driving shaft 5. A driven gear 9 is sleeved on the left part of the driven shaft 8, and bearings 10 are installed at both ends of the driving shaft 5 and both ends of the driven shaft 8. The diameter size of the driving gear 7 is half of the diameter size of the driven gear 9, and the driving gear 7 and the driven gear 9 are meshed with each other;
[0024] Specifically, the driving bevel gear 4 and the driven bevel gear 6 are meshed with each other, and the driving gear 7 and the driven gear 9 are meshed with each other to form a set of reduction gear sets. The driving bevel gear 4 is driven to rotate by the motor 2 at the end of the machine shaft 3. By means of the meshing structure, the driven bevel gear 6 is driven to rotate, and then the driving gear 7 rotates, and under the action of the meshing structure, the driven gear 9 is driven to rotate, so as to achieve the purpose of speed reduction;
[0025] The middle part of the left end face of the driven shaft 8 is connected to a connecting shaft 11, a buffer shaft sleeve 12 is sleeved outside the shaft end of the connecting shaft 11, and a torsion spring 13 is connected between the inner wall of the buffer shaft sleeve 12 and the outer wall of the connecting shaft 11;
[0026] Specifically, the connecting shaft 11 is used to connect the speed reducer to the barrier gate. A buffer bushing 12 is separately configured at the end of the connecting shaft 11. There is good rotatability between the buffer bushing 12 and the connecting shaft 11. The two are connected by a torsion spring 13, and there is a pulling elastic force between them. Under the action of the torsion spring 13, there is torsional elasticity between the connecting shaft 11 and the buffer bushing 12. That is, after the buffer bushing 12 is externally connected to the barrier gate, the barrier gate can rotate together with the connecting shaft 11, but the barrier gate can also rotate at a certain angle relative to the connecting shaft 11. This enables the barrier gate to rotate at a small angle on the basis of rotating together with the connecting shaft 11, so as to avoid damage to the barrier gate when a pedestrian accidentally operates and pushes a stopped barrier gate.
[0027] The lower right corner inside the chassis 1 is fixedly connected with a lubricating oil tank 14. The upper surface of the lubricating oil tank 14 is connected with an upper delivery pipe 15. The top end of the upper delivery pipe 15 is vertically connected with a connecting pipe 16. The end of the connecting pipe 16 is fixedly connected with a diversion pipe 17. The diversion pipe 17 is arranged directly above the driving gear 7 and the driven gear 9. The diversion pipe 17 is communicated with the lubricating oil tank 14 through the connecting pipe 16 and the upper delivery pipe 15. A drip pipe 18 is fixedly connected below the diversion pipe 17. There are two drip pipes 18 in total, and the tapered openings of the drip pipes 18 respectively correspond to the driving gear 7 and the driven gear 9.
[0028] Specifically, an independent oil pump is equipped in the lubricating oil tank 14. The oil pump pumps the lubricating oil into the upper delivery pipe 15, transports it to the diversion pipe 17 through the connecting pipe 16, and finally drips out from the two drip pipes 18. The drip pipes 18 are respectively aligned with the driving gear 7 and the driven gear 9. Therefore, the lubricating oil dripping out from the drip pipes 18 will drip on the driving gear 7 and the driven gear 9, lubricating and maintaining the driving gear 7 and the driven gear 9, and effectively preventing the phenomenon of gear locking.
[0029] The working principle of the present utility model is:
[0030] Inject sufficient lubricating oil into the lubricating oil tank 14, and then connect the buffer bushing 12 to the connecting part of the barrier gate. With the pulling elasticity of the torsion spring 13 connected between the buffer bushing 12 and the connecting shaft 11, the barrier gate can rotate at a certain angle around the connecting shaft 11, thereby avoiding the damage to the barrier gate caused by pedestrians forcibly pushing the barrier gate. After the motor 2 in the speed reducer starts, it will first drive the driving bevel gear 4 to rotate. The driving bevel gear 4 then drives the driven bevel gear 6 to rotate, and then the driving shaft 5 rotates, the driving gear 7 rotates, and the driven gear 9 rotates immediately, driving the connecting shaft 11 to rotate. In this way, the barrier gate connected to the buffer bushing 12 will rotate to complete the operation of opening and closing the passage. When the barrier gate runs with a jamming fault, it is necessary to start the oil pump in the lubricating oil tank 14. The lubricating oil is pumped into the upper delivery pipe 15, transported to the diversion pipe 17 through the connecting pipe 16, and finally drips out from the two drip pipes 18 onto the driving gear 7 and the driven gear 9 to directly lubricate and maintain the driving gear 7 and the driven gear 9.
[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
