TECHNICAL FIELD
[0001] The utility model relates to car washer technical field, concretely is a car washer high pressure rotating mechanism. BACKGROUND
[0002] The car washer is widely used for washing vehicles, and the vehicle is parked in the washing area. The car washer moves back and forth along the direction of the vehicle. The high-pressure water is lifted and rotated according to the height and shape of the vehicle. The vehicle is washed by simulation scanning. Especially for the front windshield or trunk and the front part of the vehicle, the high-pressure rotating water jet can rotate at an angle. The high-pressure water jet can directly spray the different parts of the vehicle to ensure the pressure of the water jet on the surface of the vehicle and the constant distance and impact force between the car washer and the vehicle. Therefore, the dust and soil on the surface of the vehicle can be effectively washed away.
[0003] As shown in Figure 1 , the car washer usually includes a washing platform 1 at the bottom, which has a track. A washing moving frame 2 can move on the track. The washing moving frame 2 has a rotating water spraying roller 3 inside. The rotating water spraying roller 3 is connected to the output shaft of a speed reducer 7 of a high-pressure rotating drive mechanism A through bearings 4 at both ends. The rotating water spraying roller 3 is rotated based on the high-pressure rotating drive mechanism A, so that the rotating water spraying roller 3 is opposite to the position that needs to be sprayed.
[0004] As shown in Figure 2 , the rotating water spraying roller 3 is provided with a water supply and power supply structure at the upper part, which is stored in a drag chain 14. The high-pressure rotating drive mechanism A at both ends is provided with a photoelectric detector 5. The photoelectric detectors 5 on both sides are used to detect whether there is an object between them. When there is an object, the photoelectric detectors 5 can pause or lift to avoid collision and play a role in preventing collision.
[0005] As shown in Figure 4 , at present, the rotating water spraying roller 3 is usually controlled by a rotating motor 8, proximity switches (including front proximity switch 13, middle proximity switch 12, and rear proximity switch 29), etc. A lifting pulley assembly 6 is installed on both sides of the washing moving frame 2 and can move up and down in the washing moving frame 2. A speed reducer 7 is installed on the side of the lifting pulley assembly 6. The rotating motor 8 is connected to the speed reducer 7. The output shaft of the speed reducer 7 is connected to a flange 11 and a limiting frame 10. Three proximity switches are installed on both sides and the upper part of the lifting pulley assembly 6. A drag chain frame 9 is also installed on the upper side of the front part of the speed reducer 7. When the limiting frame 10 rotates and contacts the lower surface of the drag chain frame 9, it is limited and positioned. Therefore, the limiting frame 10 can only rotate at a certain angle on the lower side of the drag chain frame 9.
[0006] An angle sensor 15 connected to the shaft of the speed reducer 7 is also installed on the lifting pulley assembly 6, which is used to detect the rotation angle (the above content, please refer to the content in Figures 1-4 ).
[0007] The existing high-pressure rotating drive mechanism in the above-mentioned flushing process, when washing the front of the vehicle, the high-pressure rotating mechanism rotates by a certain angle, so that the high-pressure water is directly opposite the front of the vehicle to be washed, when washing the roof of the vehicle, the high-pressure rotating mechanism rotates to the top of the vehicle to be washed, and the high-pressure water is directly opposite the top, when washing the tail of the vehicle to be washed, the high-pressure rotating mechanism rotates by a certain angle, so that the high-pressure rotating mechanism is directly opposite the tail of the vehicle to be washed.
[0008] In the car washing process, when the number of cars to be washed reaches a certain value, due to the small change in the rotation angle, the high-pressure water knife is repeatedly rotated back and forth, so that only a part of the turbine and the worm in the speed reducer in the rotating mechanism is worn out, when a certain number of cars are washed, the water knife should be rotated to a certain angle, and a certain time is needed to maintain the time to wash the front, roof and tail of the vehicle.
[0009] However, due to the internal mechanical wear and tear and the lubricating oil of the speed reducer, the internal wear and tear and the matching gap become larger and larger, the rotation of the car washing by a certain angle cannot be maintained, and at this time the motor is in a temporary power output moment, and then the next water knife rotation is not in place, the accumulated error becomes larger and larger, resulting in that the rotating water knife cannot rotate to the front, roof and tail of the vehicle, so that car washing failures occur frequently, and the system is unstable.
