Detailed implementation manner

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-3As shown in the figure, a hydraulic support cleaning device includes a support frame 1. On one side of the support frame 1, a U-shaped seat 2 is installed. Inside the bottom side of the U-shaped seat 2, a servo motor 3 is installed. The output end of the servo motor 3 is equipped with a semi-gear 4. Through holes are opened in both sides of the U-shaped seat 2. Slide rods 5 are slidably installed in the through holes. One end of each slide rod 5 is fixedly connected with a hollow plate 6 in a matching manner. Tooth teeth 7 are equidistantly installed inside both sides of the hollow plate 6. When the semi-gear 4 operates, it will mesh with the tooth teeth 7. On the top side of the hollow plate 6, an installation frame 8 is installed. The installation frame 8 is U-shaped. Sponge pads 9 are symmetrically installed on the inner walls of both sides of the installation frame 8. A control panel 38 is installed on one side of the support frame 1. During operation, in actual application, after the column is cleaned, residual moisture remains on the surface of the column. During the air-drying process, some impurities will adhere to the surface of the column, thus forming stains or rust, which will affect the quality and service life of the column. When the hydraulic support is cleaned, it comes out from one end of the conveying roller 11 and enters the area where the installation frame 8 is located. At this time, the servo motor 3 is started through the control panel 38 to drive the semi-gear 4 to rotate. When the semi-gear 4 meshes with the tooth teeth 7, it will push the hollow plate 6 to slide in the through hole through the slide rod 5, causing the hollow plate 6 and its installation frame 8 to move. As the semi-gear 4 continues to rotate, when the semi-gear 4 disengages from the tooth teeth 7 on one side and meshes with the tooth teeth 7 on the other side, it will push the hollow plate 6 to move in the reverse direction, so that the installation frame 8 and the sponge pads 9 continuously move back and forth on the surface of the column, thereby wiping the surface of the cleaned column to ensure that the surface of the column is clean and dry, and improving the cleaning effect of the column.

[0027] Please refer to Figures 1-5As shown in the figure, two rotating shafts 10 are symmetrically and rotatably installed between the two sides of the support frame 1. A conveying roller 11 is installed on the outer wall of the rotating shaft 10. Three support rollers 12 are equidistantly installed between the two sides of the support frame 1 through shaft cooperation. An L-shaped plate 13 is installed on one side of the support frame 1. A conveying motor 14 is installed inside the L-shaped plate 13. One end of the rotating shaft 10 is cooperatively connected to the output end of the conveying motor 14. A driving wheel 15 and a driven wheel 16 are cooperatively installed on the outer wall of one end of the rotating shaft 10. The driving wheel 15 and the driven wheel 16 are cooperatively connected by a belt 17. During operation, in practical applications, through conveying, it is ensured that the columns pass through each cleaning, brushing and other workstations in accordance with the established process, avoiding interruption or chaos, and making the entire operation process proceed orderly. The disassembled columns are placed on the conveying roller 11 near one end of the annular pipe 19. The conveying motor 14 is started to drive the rotation of the rotating shaft 10. The driving wheel 15 rotates accordingly. Through the transmission of the belt 17, the driven wheel 16 is driven to rotate, so that the other rotating shaft 10 rotates synchronously. The rotating shaft 10 drives the conveying roller 11 to rotate synchronously. During the rotation of the conveying roller 11, the columns are pushed to move along the direction of the conveying roller 11. The support rollers 12 play a role in assisting in supporting and stabilizing the columns, ensuring that the columns remain stable during the conveying process.

[0028] Please refer to Figure 1 、 2 Figures 4 and 5, two sets of two support columns 18 are symmetrically fixedly connected to one end of the support frame 1. A ring-shaped pipe 19 is cooperatively fixedly connected to the top side of each set of support columns 18. Nozzles 20 are installed inside the ring-shaped pipes 19. A conveying pipe 21 is cooperatively connected between the ring-shaped pipes 19. A water inlet pipe 22 is connected to the outer wall of the conveying pipe 21.

[0029] A medicine inlet pipe 23 is installed on the outer wall of one end of the conveying pipe 21. A chute is opened at the top end of the medicine inlet pipe 23. A sliding plate 24 is slidably installed inside the chute. A medicine inlet 25 is opened inside one end of the sliding plate 24. A support rod 26 is installed on the bottom side of the sliding plate 24. One end of the support rod 26 extends into the conveying pipe 21 and is fixedly connected to a flow blocking plate 27. Two springs 28 are equidistantly installed between the outer wall of the support rod 26 and the inner wall of the medicine inlet pipe 23.

[0030] The medicine inlet pipe 23 is installed at one end where the column enters, and the annular pipe 19 away from the medicine inlet pipe 23 is for flushing. During operation, after the hydraulic support finishes its operation, a large amount of coal dust, oil stains and other impurities will inevitably adhere to the surface of the column, which will cause corrosion to the surface of the column. Therefore, a cleaning device is needed. Water enters the conveying pipe 21 through the water inlet pipe 22. When the water flows in the conveying pipe 21, the pressure of the water acts on the baffle 27, overcoming the pulling force of the spring 28, so that the baffle 27 drives the support rod 26 and the sliding plate 24 to slide in the chute. As it slides, the medicine inlet 25 gradually aligns with the medicine inlet pipe 23, and the washing medicine can enter the conveying pipe 21 through the medicine inlet 25 and mix with the water to form a washing liquid. The mixed washing liquid is conveyed to one of the annular pipes 19 through the conveying pipe 21, and then sprayed out from the nozzle 20 in the annular pipe 19 to clean and decontaminate the passing column. At the annular pipe 19 away from the medicine inlet pipe 23, the liquid sprayed out from the nozzle 20 in this annular pipe 19 flushes the residual washing liquid and stains on the surface of the column to achieve a good cleaning effect.

[0031] Please refer to Figure 1 , 2 , as shown in Fig. 5, support columns 29 are symmetrically installed on both sides of the support frame 1. The support columns 29 are located between the two annular pipes 19. A sweeping brush assembly is installed on the top side of the support column 29. The sweeping brush assembly includes a mounting ring 30. The mounting ring 30 is fixed on the top side of the support column 29. An annular groove 31 is formed in the mounting ring 30. An annular slider 32 is slidably installed in the annular groove 31. A cleaning brush 33 is assembled on the inner wall of the annular slider 32. A toothed ring 34 is installed on the outer wall of the annular slider 32. A mounting ear 35 is installed on the outer wall of the mounting ring 30. A driving motor 36 is installed on one side of the mounting ear 35. The output end of the driving motor 36 is installed with a first gear 37, and the first gear 37 meshes with the toothed ring 34. During operation, in practical applications, simply relying on flushing may not be able to completely remove some stubborn stains, impurities or dirt. Start the driving motor 36 to drive the first gear 37 to rotate, which will drive the toothed ring 34 to rotate, so that the annular slider 32 makes a circular motion in the annular groove 31, and the cleaning brush 33 also moves accordingly. When the column passes through the sweeping brush assembly, the cleaning brush 33 will contact the surface of the column and perform a sweeping action to further clean the stubborn stains and impurities remaining on the surface of the column and improve the cleaning effect.

[0032] Working principle: Place the disassembled column on the conveying roller 11 near one end of the annular pipe 19. Start the conveying motor 14 to drive the rotation of the rotating shaft 10, and the driving wheel 15 rotates accordingly. Through the transmission of the belt 17, the driven wheel 16 is driven to rotate, so that another rotating shaft 10 rotates synchronously. The rotating shaft 10 drives the conveying roller 11 to rotate synchronously. During the rotation of the conveying roller 11, the column is pushed to move along the direction of the conveying roller 11. The supporting roller 12 plays a role in assisting in supporting and stabilizing the column to ensure that the column remains stable during transportation;

[0033] At the same time, water enters the conveying pipe 21 through the water inlet pipe 22. When the water flows in the conveying pipe 21, the pressure of the water acts on the flow blocking plate 27, overcoming the pulling force of the spring 28, so that the flow blocking plate 27 drives the support rod 26 and the sliding plate 24 to slide in the chute. As it slides, the medicine inlet 25 gradually aligns with the medicine inlet pipe 23, and the washing medicine can enter the conveying pipe 21 through the medicine inlet 25 to be mixed with water to form a washing liquid. The mixed washing liquid is conveyed through the conveying pipe 21 to one of the annular pipes 19, and then sprayed out from the nozzle 20 in the annular pipe 19 to clean and decontaminate the passing column;

[0034] The column continues to move to the sweeping brush assembly: Start the driving motor 36 to drive the first gear 37 to rotate, so the toothed ring 34 will be driven to rotate, making the annular slider 32 move in a circular motion in the annular groove 31, and the cleaning brush 33 also moves accordingly. When the column passes through the sweeping brush assembly, the cleaning brush 33 will contact the surface of the column and perform a sweeping action to further clean the stubborn stains and impurities remaining on the surface of the column and improve the cleaning effect;

[0035] The column continues to move to the annular pipe 19 away from the medicine inlet pipe 23. The liquid sprayed out from the nozzle 20 in this annular pipe 19 flushes the remaining washing liquid and stains on the surface of the column to achieve a good cleaning effect;

[0036] The column enters the area where the installation frame 8 is located: When the hydraulic support is cleaned, it comes out from one end of the conveying roller 11 and enters the area where the installation frame 8 is located. At this time, start the servo motor 3 through the control panel 38 to drive the half gear 4 to rotate. When the half gear 4 meshes with the tooth 7, it will push the hollow plate 6 to slide in the through hole through the slide rod 5, so that the hollow plate 6 and its installation frame 8 move. As the half gear 4 continues to rotate, when the half gear 4 disengages from one side of the tooth 7 and meshes with the tooth 7 on the other side, it will push the hollow plate 6 to move in the reverse direction, so that the installation frame 8 and the sponge pad 9 continuously move back and forth on the surface of the column, thereby wiping the surface of the cleaned column to ensure that the surface of the column is clean and improve the cleaning effect of the column.
