[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Refer to Figures 1-3 , a trolley drive structure for a single-track non-contact automatic car wash machine, including a track 1. A trolley main body 3 is arranged outside the track 1. A motor reducer 2 is arranged on the front surface of the trolley main body 3. A driving wheel 4 is arranged on the rear surface of the motor reducer 2. The driving wheel 4 is arranged between the inner walls of the trolley main body 3. The lower end of the driving wheel 4 is in contact with the surface of the track 1. The driving wheel 4 is rotatably connected to the trolley main body 3. Two driven wheels 5 are arranged between the inner walls of the trolley main body 3. The diameters of the two driven wheels 5 are both smaller than the diameter of the driving wheel 4. By configuring two driven wheels 5 and one driving wheel 4, a stable triangular layout is formed. This layout can significantly improve the stability of the trolley during operation. The lower ends of the two driven wheels 5 are both in contact with the surface of the track 1. Two limiting wheels 6 are rotatably connected to one side surface of the trolley main body 3. The two limiting wheels 6 are respectively arranged on both sides of the track 1. Shafts 7 are arranged at both ends of the driven wheels 5. A plurality of shafts 7 are all rotatably connected to the trolley main body 3. The two driven wheels 5 are respectively arranged on both sides of the driving wheel 4.

[0023] A plurality of mounting blocks 8 are arranged on the inner wall of the trolley main body 3. The plurality of mounting blocks 8 correspond to the plurality of shafts 7 one by one. An installation groove 9 is arranged on the side surface of the mounting block 8 close to the shaft 7. One end of the shaft 7 extends into the installation groove 9. The two driven wheels 5 can be rotated by the rotation of the shaft 7 in the installation groove 9. The shaft 7 is installed in the installation groove 9, and then the two mounting blocks 8 are fixed on the inner wall of the trolley main body 3 to realize the installation of the driven wheels 5. The operation is simple and convenient for maintenance personnel to repair the driven wheels.

[0024] A plurality of bolts 10 are arranged outside the trolley main body 3. One ends of the bolts 10 all penetrate through the trolley main body 3 and are threadedly connected to the mounting blocks 8. A gasket 11 is arranged between the trolley main body 3 and the bolts 10. By screwing the bolts 10, the mounting blocks 8 are fixed on the inner wall of the trolley main body 3.

[0025] A plurality of operation grooves 12 are arranged on the inner wall of the trolley main body 3. The operation grooves 12 provide installation and disassembly space for maintenance personnel, facilitating the installation and disassembly of the mounting blocks 8. The plurality of operation grooves 12 correspond to the plurality of shafts 7 one by one. A positioning groove 13 is arranged on the inner wall of the operation groove 12 far from the mounting block 8. The mounting block 8 is matched with the positioning groove 13. The arranged positioning groove 13 facilitates the positioning of the driven wheels 5.

[0026] The cross-sectional shape of the outer surface of the mounting block 8 is a regular hexagon, which is convenient for holding the mounting block 8 with the mounting tool, and the cross-sectional shape of the inner wall of the mounting block 8 is a circle.

[0027] The surfaces of the two driven wheels 5 are treated with anti-skid treatment to increase the friction between the driven wheels 5 and the track 1.

[0028] Working principle: First, the motor reducer 2 drives the driving wheel 4, which contacts the track 1. Using friction, the rotation of the driving wheel 4 drives the crane body 3 to move along the track 1. At the same time, the movement of the crane body 3 will also drive the driven wheels 5 to rotate. The main function of the two driven wheels 5 is to maintain the balance of the crane body 3 and ensure that under any external force, at least one driven wheel 5 always keeps in contact with the track 1, thereby ensuring the smooth movement of the crane body 3.

[0029] Specifically, when the gravity on one side is greater than that on the other side, the driven wheel 5 on the side with less gravity may have a slight tendency to lift up, and may even slightly leave the surface of the track 1. However, due to the support of the driving wheel 4 and the driven wheel 5 on the other side, the main body 3 of the overhead travelling vehicle will not tilt significantly. This design effectively solves the problem caused by the unstable center of gravity.

[0030] During the installation process, please pay attention to the following points:

[0031] 1. The driving wheel 4 and the two driven wheels 5 need to be in contact with the track 1 at the same time, ensuring that the bottoms of the three wheels remain on the same horizontal line.

[0032] 2. Ensure the installation accuracy of the driving wheel 4 and the two driven wheels 5 to maintain the stability and operating efficiency of the overhead crane.

[0033] Through this carefully designed transmission structure, the present invention not only improves the stability and reliability of the single-track contactless automatic car washing machine, but also simplifies the installation and maintenance process, providing users with an efficient and economical car washing solution.

[0034] The crane transmission structure of this single track non-contact automatic car washing machine has some advantages as follows:

[0035] 1. Enhanced stability: By increasing the number of driven wheels 5 and optimizing the layout, the stability of the structure is significantly improved.

[0036] 2. Balanced center of gravity: The design ensures that at least one driven wheel 5 is always in contact with the track 1, effectively solving the problem of unstable center of gravity.

[0037] 3. Anti-deformation ability: Even when subjected to uneven external forces, the forces inside the structure can be automatically redistributed to maintain the shape and balance state unchanged.

[0038] 4. Reduced maintenance: Due to the structural stability and anti-deformation ability, the maintenance requirements caused by unstable center of gravity or eccentricity are reduced.

[0039] 5. Improved efficiency: The optimized transmission structure can improve the operating efficiency of the car wash machine and reduce the downtime caused by structural problems.

[0040] 6. Simplified installation: Three wheels (the driving wheel 4 and two driven wheels 5) need to be in contact with the track 1 simultaneously, which simplifies the installation process.

[0041] 7. Cost-effectiveness: The simplification and stability of the structure may reduce the manufacturing and maintenance costs.

[0042] 8. User-friendly: The improved design makes the operation more convenient and enhances the user experience.

[0043] 9. Strong adaptability: The structural design allows the performance to be maintained under different conditions and adapts to various car wash environments.

[0044] 10. Enhanced safety: Reduce the potential safety risks caused by unstable center of gravity.

[0045] These advantages make the overhead crane transmission structure of this automatic car wash machine more reliable, efficient and economical in practical applications.

[0046] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
