Through the rotation of the lifting motor 11 and the transmission of the reduction box 12, the lifting motor 11 can drive the drive shaft 14 installed between the two equipment boxes 1 to rotate.
[0028] A vertical track 8 is installed on the right side wall of the equipment box 1 on the left side. The track 8 is an angle steel. A limiting plate 83 is installed at the lower end of the angle steel to close the lower end of the angle steel. The angle steel includes a fixed surface 82 and a guide surface 81. The fixed surface 82 of the angle steel is fixedly installed on the equipment box 1. The guide surface 81 forms a track 8 perpendicular to the surface of the equipment box 1. A sliding component 3 is installed on the track 8, and the sliding component 3 can move up and down along the track 8.
[0029] The sliding assembly 3 includes a first mounting plate 31 and a second mounting plate 35. Vertical rollers 32 and transverse rollers 34 that are perpendicular to each other are installed on the outer side surface of the first mounting plate 31. A guide rail channel is formed between the transverse rollers 34 and the vertical rollers 32. The guide surface 81 is located in the guide rail channel. The transverse roller 34 contacts the fixed surface 82, and the vertical roller 32 contacts the guide surface 81. The vertical rollers 32 and the transverse rollers 34 are correspondingly arranged, and two groups of correspondingly arranged vertical rollers 32 and transverse rollers 34 are installed on the outer side surface of the first mounting plate 31.

The second mounting plate 35 is provided with a torsion wheel 36 perpendicular to the transverse roller 34 through a roller frame 33. The torsion wheel 36 is in contact with the guide surface 81, and a guide rail channel is further formed between the torsion wheel 36 and the vertical roller 32. By moving the bolts in the slot holes 30, the position of the second mounting plate 35 on the first mounting plate 31 can be adjusted, so that the contact distance between the torsion wheel 36 and the guide surface 81 can be adjusted, and the installation of the torsion wheel 36 is convenient.
[0031] A fixed pulley 51 is installed on the top lower surface of the connection box 2 directly above the sliding assembly 3, and a sling drum 6 is installed on the drive shaft 14 opposite to the fixed pulley 51. The sling drum 6 consists of a mounting tube 61 and two discs fixedly mounted at both ends of the mounting tube 61. The mounting tube 61 is fixedly mounted on the drive shaft 14. A sling rack 37 is installed on the upper part of the inner side surface of the first mounting plate 31. The cross section of the sling rack 37 is A sling mounting rod 38 is installed between the sling frame 37 and the first mounting plate 31, and a sling 5 connected to the sling mounting rod 38 through a fixed pulley 51 is installed on the sling disc 6, and the sling 5 uses a nylon rope.
[0032] A track 8 and a sliding assembly 3 installed on the track 8 are also provided on the left side wall of the equipment box 1 on the right, and a sling drum 6 and a sling 5 connected to the sliding assembly 3 through a fixed pulley 51 are also installed on the connection box 2 and the drive shaft 14 on the right, wherein the structure of the track 8, the sliding assembly 3, the sling drum 6 and the sling rack 37 at the equipment box 1 on the right are exactly the same as the structure of the track 8, the sliding assembly 3, the sling drum 6 and the sling rack 37 at the equipment box 1 on the left, and the track 8 and the sliding assembly 3 on the equipment box 1 on the right and the equipment box 1 on the left are installed correspondingly.
[0033] A top brush 4 is installed between the sliding assembly 3 installed on the right equipment box 1 and the left equipment box 1. When the lifting motor 11 drives the driving shaft 14 to rotate, the sling disc 6 rotates accordingly, and the sliding assembly 3 can drive the top brush 4 to rise and fall along the track 8 by retracting and releasing the sling 5 on the sling disc 6.
[0034] Two position sensors 15 are also installed on the right side wall of the equipment box 1 at the rear of the track 8 on the left side of the equipment box 1. The position sensors 15 are electrically connected to the computer host. The two position sensors 15 are respectively located on the right side walls corresponding to the upper and lower parts of the track 8. The position sensor 15 adopts the Omron E2B proximity sensor. The upper and lower ends of the first mounting plate 31 of the sliding assembly 3 installed on the track 8 of the left equipment box 1 are respectively installed with two limit plates 39 opposite to the position sensor 15. The limit plates 39 can block the position sensor 15. When the first mounting plate 31 is installed When the limit plate 39 at the upper end of the plate 31 moves upward with the sliding assembly 3 and blocks the upper position sensor 15, the computer host receives the electrical signal sent by the position sensor 15, controls the lifting motor 11 to stop rotating, and stops the top brush 4 from rising; when the limit plate 39 at the lower end of the first mounting plate 31 moves downward with the sliding assembly 3 and blocks the lower position sensor 15, the computer host receives the electrical signal sent by the position sensor 15, controls the lifting motor 11 to stop rotating, and stops the top brush 4 from descending, thereby ensuring that the top brush 4 is lifted and lowered within a specified height range.
[0035] Since the top brush 4 rotates during operation, the sliding components 3 at both ends of the top brush 4 can generate a torque perpendicular to the guide surface 81 when the top brush 4 rotates, causing the transverse roller 34 and the vertical roller 32 to be severely stressed. After a period of use, the transverse roller 34 and the vertical roller 32 will be deformed, causing the guide rail channel between the transverse roller 34 and the vertical roller 32 to become wider, and the transverse roller 34 and the vertical roller 32 can no longer clamp the angle steel, resulting in violent shaking of the top brush 4 during the up and down movement, causing damage to the car being cleaned. The present invention installs a torsion wheel 36 between the transverse rollers 34. The torsion wheel 36 is perpendicular to the transverse roller 34, that is, parallel to the vertical roller 32, so that clamping is formed on both sides of the guide surface 81, and the torsion wheel 36 and the two vertical rollers 32 are respectively distributed at the two ends and the middle of the first mounting plate 31, forming a three-point clamping, thereby preventing the transverse roller 34 from contacting and rubbing with the guide surface 81 due to torque, and the transverse roller 34 will not be deformed due to torque, thereby extending the service life of the sliding component 3 and the track 8 and reducing the failure rate.
[0036] The top brush 4 is installed on the middle part of the inner side surface of the first mounting plate 31 of the two sliding assemblies 3 through the right connecting piece 45 and the left connecting piece 44. The top brush 4 is composed of a brush body 42 and a rotating shaft 41. The left end of the rotating shaft 41 is installed on the left connecting piece 44. The right end of the rotating shaft 41 is installed with a driving motor 7 for driving the rotating shaft 41 to rotate. The driving motor 7 is powered by an external power supply, and the driving motor 7 is connected to the sliding assembly 3 through the right connecting piece 45.
