The shafts of the two first cleaning wheels are connected by a first belt. Movable plates for supporting the second cleaning wheels are provided on both sides of the trolley. The movable plates are slidably connected to the sidewalls of the lifting frame. When the lifting frame is raised and lowered, the movable plates on both sides are driven to move synchronously inward or outward through a linkage mechanism. When the first cleaning wheels rotate, the second cleaning wheels on the same side are driven to rotate through a connecting mechanism.

[0007] The linkage mechanism includes drive rods symmetrically arranged on the inner side of the moving plate, and drive plates arranged in the trolley that correspond one-to-one with the moving plate. The drive plates are provided with guide holes, the guide holes include a vertical part and an arc-shaped part provided at the lower end of the vertical part, the arc-shaped part is inclined outward from top to bottom, and a drive wheel that cooperates with the guide hole is provided at one end of the inner side of the drive rod.

[0017] 1. This invention includes a trolley supported on and traveling on a stainless steel trough, a lifting frame disposed within the trolley and raised and lowered within the trolley, first cleaning wheels symmetrically arranged within the lifting frame for cleaning the bottom of the stainless steel trough, and second cleaning wheels disposed on both sides of the lifting frame for cleaning the side walls of the stainless steel trough. The shafts of the two first cleaning wheels are connected by a first belt. Movable plates supporting the second cleaning wheels are provided on both sides of the trolley. The movable plates are slidably connected to the side walls of the lifting frame. When the lifting frame is raised or lowered, the movable plates on both sides move synchronously inward or outward through a linkage mechanism. When the first cleaning wheels rotate, the second cleaning wheels on the same side rotate through a connecting mechanism. When cleaning the stainless steel trough, the trolley is supported on and travels on the stainless steel trough. The lifting frame descends, and the first cleaning wheels rotate to clean the bottom of the stainless steel trough. When the lifting frame descends, the second cleaning wheels on both sides move synchronously outward under the action of the linkage mechanism, and the second cleaning wheels clean the side walls of the stainless steel trough. As the trolley moves forward, the first and second cleaning wheels clean the inner walls of the stainless steel trough. No manual cleaning is required, reducing labor intensity and improving cleaning efficiency.

[0018] 2. The linkage mechanism in this invention includes drive rods symmetrically arranged on the inner side of the moving plate, and drive plates arranged in the trolley corresponding to the moving plate one-to-one. Each drive plate has a guide hole, which includes a vertical portion and an arc-shaped portion at the lower end of the vertical portion. The arc-shaped portion slopes outward from top to bottom. One end of the inner side of each drive rod has a drive wheel that mates with the guide hole. When the lifting frame descends, under the action of the guide hole and the drive wheel, the second cleaning wheels on both sides move outward synchronously, contacting the side walls of the stainless steel tank, thereby cleaning the side walls of the stainless steel tank. The mechanical structure achieves linkage between the lifting of the lifting frame and the movement of the second cleaning wheels, resulting in low cost and high reliability.

[0025] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0026] like Figure 1 and Figure 2 As shown, an automatic cleaning device for stainless steel tanks includes a trolley 1 supported on and moving on a stainless steel tank; a lifting frame 2 disposed within the trolley 1 and raised and lowered within the trolley 1; first cleaning wheels 4 symmetrically arranged within the lifting frame 2 for cleaning the bottom of the stainless steel tank; and second cleaning wheels 5 disposed on both sides of the lifting frame 2 for cleaning the sidewalls of the stainless steel tank. The shafts of the two first cleaning wheels 4 are connected by a first belt 6. Movable plates 7 supporting the second cleaning wheels 5 are provided on both sides of the trolley 1. The movable plates 7 are slidably connected to the sidewalls of the lifting frame 2. When the lifting frame 2 is raised and lowered, the two cleaning wheels 5 are driven by a linkage mechanism. The moving plate 7 moves inward or outward synchronously. When the first cleaning wheel 4 rotates, it drives the second cleaning wheel 5 on the same side to rotate through the connecting mechanism. When cleaning the stainless steel tank, the trolley 1 is supported on the stainless steel tank and moves on the stainless steel tank. The lifting frame 2 descends, and the first cleaning wheel 4 rotates to clean the bottom of the stainless steel tank. When the lifting frame 2 descends, the second cleaning wheels 5 on both sides move outward synchronously under the action of the linkage mechanism. The second cleaning wheels 5 clean the side walls of the stainless steel tank. As the trolley 1 moves forward, the first cleaning wheel 4 and the second cleaning wheel 5 clean the inner wall of the stainless steel tank. No manual cleaning is required, which reduces labor intensity and improves cleaning efficiency.

[0027] like Figure 3 and 4As shown, the linkage mechanism includes drive rods 8 symmetrically arranged inside the moving plate 7, and drive plates 9 arranged inside the trolley 1 corresponding to the moving plate 7. The upper end of the drive plate 9 is fixed to the inner wall of the trolley 1. The drive plate 9 is provided with a guide hole 10, which includes a vertical part and an arc-shaped part 11 at the lower end of the vertical part. The arc-shaped part 11 is inclined outward from top to bottom. One end of the drive rod 8 is provided with a drive wheel 12 that cooperates with the guide hole 10. When the lifting frame 2 descends, under the action of the guide hole 10 and the drive wheel 12, the second cleaning wheels 5 on both sides move outward synchronously. The second cleaning wheels 5 contact the side walls of the stainless steel tank, thereby cleaning the side walls of the stainless steel tank. The lifting of the lifting frame 2 and the movement of the second cleaning wheels 5 are linked through a mechanical structure, which is low in cost and has good reliability.

[0028] like Figure 3 As shown, the connecting mechanism includes a first connecting rod 13, a second connecting rod 14, a second belt 15, and a third belt. The first connecting rod 13 and the second connecting rod 14 are hinged, and a rotatable pin is provided at the hinge point. The end of the first connecting rod 13 away from the second connecting rod 14 is rotatably connected to the shaft of the first cleaning wheel 4, and the end of the second connecting rod 14 away from the first connecting rod 13 is rotatably connected to the shaft of the second cleaning wheel 5. The shaft of the first cleaning wheel 4 is connected to the shaft of the second cleaning wheel 5 through the second belt 15 and the third belt. During operation, when the first cleaning wheel 4 rotates, it drives the second belt 15 to move, which in turn drives the third belt, causing the second cleaning wheel 5 to rotate accordingly. Two coaxial pulleys are fixed on the pin at the hinge point of the first connecting rod 13 and the second connecting rod 14. One pulley is connected to the shaft of the first cleaning wheel 4 through the second belt 15, and the other pulley is connected to the shaft of the second cleaning wheel 5 through the third belt. When the second cleaning wheel 5 moves outward, the rotation of the second cleaning wheel 5 will not be interfered with by setting the first connecting rod 13, the second connecting rod 14, the second belt 15, and the third belt.

[0029] like Figure 1 As shown, the trolley 1 is provided with four traveling wheels 3 on both sides that cooperate with the side wall of the stainless steel groove. The outer cylindrical surface of the traveling wheel 3 is provided with a groove that cooperates with the side wall of the stainless steel groove.

[0030] like Figure 1 and Figure 2 As shown, the front and rear ends of the lifting frame 2 are slidably connected to the inner wall of the trolley 1 through a guide rail slider pair. The upper end of the trolley 1 is provided with a hydraulic cylinder 16 that drives the lifting frame 2 to rise and fall. The cylinder body end of the hydraulic cylinder 16 is fixed to the upper end of the trolley 1, and the piston rod end of the hydraulic cylinder 16 is connected to the lifting frame 2.

[0031] like Figure 4As shown, the lifting frame 2 has a cavity 17 inside, the first belt 6 is located inside the cavity 17, and the shaft of the first cleaning wheel 4 is provided with pulleys that cooperate with the first belt 6. By placing the first belt 6 inside the cavity 17, the space occupied is reduced, and the equipment is compact.

[0032] like Figure 3 As shown, the upper end of the movable plate 7 is provided with a mounting plate 18, and the upper end of the rotating shaft of the second cleaning wheel 5 passes through the mounting plate 18 and is rotatably connected to the mounting plate 18.

[0033] like Figure 4 As shown, a sliding rod 19 is provided at one end of the inner side of the movable plate 7. The sliding rod 19 passes through the side wall of the lifting frame 2 and is slidably connected to the side wall of the lifting frame 2.

[0034] like Figure 3 As shown, the lifting frame 2 is equipped with a motor 20, and the output end of the motor 20 is connected to the shaft of the first cleaning wheel 4 through a fourth belt 21.

[0035] like Figure 3 As shown, the upper end of the lifting frame 2 has an opening corresponding to the position of the drive plate 9, and the lower end of the drive plate 9 passes through the opening.
