DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Example:

[0024] Reference Figure 1-Figure 4A device for cleaning the inner wall of a hydraulic cylinder comprises a cleaning box 1, a slide groove is provided on the cleaning box 1, and a placing plate 2 is slidably connected to the slide groove, and a slider is provided at the bottom of the placing plate 2, and both sides of the slider are in contact with the inner wall of the slide groove, a rack is fixedly connected to the bottom of the slider, and a driving machine is fixedly connected in the cleaning box 1, and the driving machine can be a hydraulic motor or a high-torque driving motor, and a gear is fixedly connected to the output end of the driving machine, and the gear is meshed with the rack.

[0025] And, if Figure 3 A placement frame 802 is also provided on the placement plate 2 to support the bottom of the hydraulic cylinder. At the same time, electric telescopic rods 8 are provided on both sides of the placement plate 2. A limit plate 801 is also provided at the output end of the electric telescopic rod 8, which can be used to limit the outside of the hydraulic cylinder. That is, the hydraulic cylinder is fixed between the placement frame 802 and the limit plate 801, so that the hydraulic cylinder is fixed on the placement plate 2 for cleaning. When the position of the placement plate 2 needs to be changed, the drive switch is started. At this time, the driving motor rotates clockwise, and the placement plate 2 will move to the right. When the driving motor rotates counterclockwise, the placement plate 2 will move to the left.

[0026] A workbench is fixedly connected to the cleaning box 1, a motor is fixedly connected to the workbench, a rotating shaft 4 is fixedly connected to the output end of the motor, a booster disk 5 is fixedly connected to the workbench through a connecting pipe, and the rotating shaft 4 is rotatably connected to the booster disk 5.

[0027] Please refer to Figure 4 As shown in the figure, a cavity is further opened in the boosting disk 5, and a liquid inlet hole 402 is opened on the outer wall of the rotating shaft 4, and the liquid inlet hole 402 is arranged in the boosting disk 5, and a guide channel 401 is further opened in the rotating shaft 4, and the guide channel 401 is connected with the liquid inlet hole 402, and the liquid inlet hole 402 is connected with the boosting disk 5, and a liquid inlet pipe 501 is fixedly connected to the boosting disk 5, and the liquid inlet pipe 501 is connected to the output end of the water pump.

[0028] A cleaning brush 6 is also fixedly connected to the outer wall of the rotating shaft 4, and a liquid spray hole 7 is opened on the rotating shaft 4, and the liquid spray hole 7 is connected to the guide channel 401. Here, the input end of the water pump can be connected to the liquid storage cylinder or the liquid storage tank. The liquid storage cylinder or the liquid storage tank is filled with a cleaning agent for cleaning oil stains, such as chlorinated solvents: such as trichloroethylene, etc., which can effectively remove stubborn oil stains and dirt, benzene solvents: such as anisole, etc., have good solubility and chemical activity, and are often used to remove high molecular weight grease and wax, and then the cleaning agent is transported to the booster disk 5 through the water pump.

[0029] At this time, start the motor to drive the rotating shaft 4 to rotate, then turn on the water pump switch, the cleaning agent will be delivered to the booster disc 5, and then delivered to the guide channel 401 through the liquid inlet hole 402, so that the cleaning brush 6 can rotate and cooperate with the spray hole 7 to clean the oil stains on the inner wall of the oil cylinder. At this time, start the switch of the driving machine again to drive the tooth plate 201 to move back and forth on the slide groove, so as to drive the oil cylinder to move, and then cooperate with the rotating cleaning brush 6 for cleaning, which can achieve the effect of combining mechanical brush force and chemical cleaning, making the cleaning effect more comprehensive and able to reduce the dirt and oil stains in the oil cylinder. At the same time, the rotation of the cleaning brush 6 can stir and rub the inner wall of the oil cylinder to bring the dirt to the surface, and the spray hole 7 can spray the cleaning agent to help dissolve and rinse the dirt, thereby improving the cleaning efficiency, so that it can meet the requirements of production and maintenance efficiency without affecting subsequent work.

[0030] In addition, a booster cylinder 3 is fixedly connected in the cleaning box 1, and a booster rod 301 is slidably connected to the booster cylinder 3. A piston is provided at one end of the booster rod 301, and the piston fits against the inner wall of the booster cylinder 3. A spring is provided in the booster cylinder 3, and the two ends of the spring are respectively against the piston and the booster cylinder 3. An air inlet pipe and an air outlet pipe 502 are respectively provided on the booster cylinder 3, and the air outlet pipe 502 is connected to the booster disk 5. Both the air inlet pipe and the air outlet pipe 502 are provided with a one-way valve.

[0031] It needs to be explained that when the tooth plate 201 moves to the left, it can be against the boost rod 301. When the tooth plate 201 is against the boost rod 301, the boost rod 301 will drive the piston to transport the gas in the boost cylinder 3 to the boost disk 5 through the outlet pipe 502. Since one-way valves are provided on the inlet pipe and the outlet pipe 502, the inlet pipe stops taking in air during this process, while the outlet pipe 502 starts to discharge air, and the spring will be compressed, thereby mixing the gas with the cleaning agent, generating a group of bubbles in the cleaning agent, thereby increasing the time that the cleaning agent stays on the inner wall of the oil cylinder, allowing the cleaning agents to have enough time to complete their work, thereby improving the cleaning efficiency of the inner wall of the oil cylinder.

[0032] When the tooth plate 201 moves to the right, it cannot collide with the boost rod 301. At this time, the compressed spring is reset, pushing the piston to drive the boost rod 301 to move to the outside. Due to the negative pressure generated in the boost cylinder 3, the air inlet pipe takes in air, and the air outlet pipe 502 stops exhausting air, thereby replenishing the gas in the boost cylinder 3 for subsequent air supply.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
