[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Reference Figures 1-4This utility model provides a device for removing oil stains from the inner wall of a diesel engine cylinder, including a workbench 9. A hydraulic telescopic rod 2 is bolted to the top of the workbench 9. A column 1 is welded to the top of the workbench 9. A horizontal frame 3 that can slide up and down is sleeved on the upper part of the column 1. A cleaning component for cleaning oil stains from the inner wall of the diesel engine cylinder is provided at one end of the horizontal frame 3. Y-shaped frames 15 are welded to both sides of the horizontal frame 3. A wedge plate 16 is welded to the bottom of the Y-shaped frame 15. Two fixed columns 19 are welded to the top of the workbench 9. A rack 17 is slidably connected inside the fixed column 19. A strip groove 21 is opened inside the rack 17. A spring 18 is provided on one side of the fixed column 19, and one end of the spring 18 is fixed to the rack 17. Two rotating columns 11 are rotatably connected to the top of the workbench 9. A torsion spring 10 is fitted around the outer circumference of the cylinder, and one end of the torsion spring 10 is fixed to the workbench 9. Gears 20 are keyed to the outer circumference of the two rotating columns 11, and the gears 20 mesh with the rack 17. The top of the two rotating columns 11 is fixed with a tray frame 5 by bolts. The bottom of the tray frame 5 is equipped with a spray assembly for secondary cleaning of the inner wall of the cylinder. The top of the workbench 9 is equipped with a guide assembly for quickly draining the waste liquid after cleaning from the inside of the cylinder. After cleaning the inner wall of the cylinder, the cleaning assembly is separated from the cylinder, and then the tray frame 5 rotates to the middle. When the two tray frames 5 come into contact and form a whole, the tray frame 5 forms a barrier between the roller brush 4 and the cylinder. The tray frame 5 can catch the residual oil dripping from the roller brush 4, thereby preventing the cleaning assembly from causing secondary pollution to the cylinder.
[0024] This utility model, it should be noted, includes a spray assembly comprising a diversion pipe 13, which is located at the bottom of the tray frame 5. Two nozzles 14 are positioned at the bottom of the diversion pipe 13. One end of the diversion pipe 13 has a connector for easy connection to an external liquid supply mechanism, providing cleaning fluid to the inner wall of the cleaning cylinder. The nozzles 14 are placed above the inner wall of the cylinder, and then spray the cleaning fluid onto the inner wall for initial cleaning. After the cleaning assembly has completed further cleaning of the inner wall, the nozzles 14 spray the inner wall of the cylinder again, thus achieving a secondary cleaning of the inner wall of the cylinder, resulting in a more thorough cleaning. The cleaning assembly includes multiple roller brushes 4 and multiple motors. Multiple roller brushes 4 are rotatably connected to the bottom of the crossbeam 3, and multiple motors are bolted to the top of the crossbeam 3, with the motor output shafts fixed to the roller brushes 4. The cleaning assembly can clean stubborn oil stains remaining on the inner wall of the cylinder. The guide assembly includes a placement trough 6 and a collection box 8. The placement trough 6 is located on the top of the workbench 9, and multiple drain troughs 7 are provided at the bottom of the placement trough 6, extending through the workbench 9. The collection box 8 is located at the bottom of the workbench 9, facilitating the collection of waste liquid flowing from the drain troughs 7 for unified treatment. A rubber strip 12 is glued to one side of the tray frame 5 to seal the gap between two tray frames 5, ensuring that the two tray frames 5 are closed. There are no gaps between them to prevent the waste liquid collected by the tray frame 5 from leaking onto the bottom cylinder, thus increasing the sealing of the tray frame 5. The outer circumference of multiple roller brushes 4 is the same as the cylinder diameter, and the central axis of the roller brushes 4 is aligned with the central axis of the cylinder. This allows the roller brushes 4 to accurately insert into the inner wall of the cylinder during the descent of the horizontal frame 3 driven by the hydraulic telescopic rod 2, and the roller brushes 4 can fit tightly against the inner wall of the cylinder. When the roller brushes 4 rotate, they can thoroughly clean the oil stains on the inner wall of the cylinder. Both tray frames 5 are set with a certain tilt angle, and two water guide pipes are set on one side of each tray frame 5. The water guide pipes are connected to the external sewage discharge hose, and then the other end of the sewage discharge hose... One end is placed in the collection box 8, so that the waste liquid with oil residue dripping from the roller brush 4 and collected on the tray frame 5 can be guided into the collection box 8, preventing the waste liquid from accumulating and overflowing on the tray frame 5. The bottom of the wedge plate 16 is provided with an inclined surface. The thickness of the wedge plate 16 is the same as the width of the strip groove 21. The inclined surface of the wedge plate 16 fits against one side inner wall of the strip groove 21, so that when the wedge plate 16 moves downward, it can squeeze the rack 17 to move towards the center in the fixed column 19. At the same time, the thickness of the wedge plate 16 is the same as the width of the strip groove 21, so that when the wedge plate 16 moves up and down in the strip groove 21, it prevents the wedge plate 16 from swaying horizontally, so that the wedge plate 16 can maintain a stable horizontal state.
[0025] The working principle of this utility model is as follows: A diesel engine cylinder block with oil stains is placed in the placement groove 6, aligning the cylinder bore with the roller brush 4. First, the external liquid supply mechanism is activated, pumping the cleaning fluid into the distribution pipe 13 via a connector. Then, the cleaning fluid is sprayed onto the cylinder block through the nozzle 14, thus performing initial cleaning of the cylinder's inner wall. Next, the hydraulic telescopic rod 2 is activated, causing the horizontal frame 3 to move downwards. The horizontal frame 3 then moves the Y-shaped frame 15, causing the wedge plate 16 to move downwards. The inclined surface at the bottom of the wedge plate 16 presses the rack 17 towards the center. The rack 17 drives the gear 20 to rotate, causing the rotating column 11 to rotate the tray frame 5 to both sides. When the inclined surface of the wedge plate 16 completely passes through the rack 17 downwards, the tray frame 5 rotates 90 degrees, thus fully opening the tray frame 5 and no longer obstructing the roller brush 4 above it. The horizontal frame 3 continues to move downwards. The crossbeam 3 drives the roller brush 4 in the cleaning assembly to insert into the inner wall of the cylinder. At this time, the motor is started, and the rotation of the motor drives the roller brush 4 to rotate, thereby the roller brush 4 further cleans the inner wall of the cylinder, removing the oil stains adhering to the inner wall. After cleaning is completed, the hydraulic telescopic rod 2 is restarted and moved upward. The hydraulic telescopic rod 2 pushes the crossbeam 3 upward to separate the cleaning assembly from the cylinder. The crossbeam 3 continues to move upward, causing the wedge plate 16 to move upward. When the inclined surface of the wedge plate 16 enters the strip groove 21, the spring 18 rebounds and pushes the rack 17 to move to both sides, thereby causing the tray frame 5 to rotate towards the middle. When the two tray frames 5 contact, the tray frames 5 form a barrier between the roller brush 4 and the cylinder, preventing the cleaning assembly from causing secondary pollution to the cylinder. Then the spray assembly cleans the inner wall of the cylinder again, thereby removing the oil stains on the inner wall of the cylinder more thoroughly.
[0026] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
