Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder cleaning technology, specifically to cleaning equipment. Background Technology

[0002] A hydraulic cylinder (mechanical device) is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device, has no transmission backlash, and provides smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. After use, the cylinder structure requires cleaning equipment to clean the inner wall of the cylinder. The cleanliness of the cylinder's inner cavity directly affects the stability and service life of the entire system.

[0003] According to CN 218079269 U, an automatic cleaning device for hydraulic cylinder barrels belongs to the field of hydraulic cylinder barrel cleaning devices. It includes a base frame and an upper frame mounted on the top of the base frame. The flipping assembly includes a mounting block mounted on the top of the base frame and a connecting shaft inserted through the mounting block. Two sets of mounting blocks are provided. A collar is sleeved on the outer side of the connecting shaft, and a support plate is mounted on the upper end of the collar. A rotating gear is also sleeved on the outer side of the connecting shaft. After cleaning, the drive motor is stopped, and a switch is used to move the electric push rod upwards, moving the cleaning brush away from the cylinder barrel. At this time, the rotating motor is turned on, causing the drive gear to rotate. When the drive gear rotates, the gear chain rotates, and the gear chain meshes with the rotating gear, thereby driving the connecting shaft to rotate the collar and support plate. The cleaned cylinder barrel is then fixedly clamped on the support plate, allowing the cylinder barrel to flip and easily empty the water inside.

[0004] However, the above equipment still has some shortcomings in use. After cleaning, the cylinder barrel lacks a drying component and can only be air-dried naturally, which is inefficient. At the same time, there are cases where the cleaning is not thorough. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a cleaning device that solves the problem that the oil cylinder barrel lacks a drying component after cleaning, can only be dried naturally, which is inefficient, and the cleaning process is also incomplete.

[0006] This utility model provides the following technical solution: a cleaning device, including a workbench, a screw rotatably mounted on the lower surface of the workbench, a threaded sleeve sleeved on the surface of the screw, a slide rod fixedly connected to the lower surface of the workbench, a slide sleeve slidably mounted on the surface of the slide rod, two movable slots opened on the upper surface of the workbench, the threaded sleeve and the slide sleeve respectively passing through the two movable slots and fixedly connected to a support plate, two placement platforms fixedly connected to the upper surface of the support plate, and a first motor fixedly mounted on the lower surface of the workbench, the output end of the first motor being fixedly connected to the screw.

[0007] The upper surface of the workbench has two sliding grooves, and a slider is slidably installed inside each of the two sliding grooves. A connecting plate is fixedly connected between the upper surfaces of the two sliders. Two short plates are fixedly connected to the upper surface of the connecting plate. A liquid outlet pipe is rotatably installed on the surface of one of the short plates, and an air outlet pipe is rotatably installed on the surface of the other short plate.

[0008] One end of the liquid outlet pipe is connected to a ring of liquid outlet nozzles, and a brush ring is fixed to one end of the liquid outlet pipe. The brush ring is provided with brush bristles. One end of the air outlet pipe is connected to a ring of air outlet nozzles, and an absorbent sponge is provided to one end of the air outlet pipe.

[0009] Preferred technical solution 1: One end of both the air outlet pipe and the liquid outlet pipe extends to the outside of the connected short plate and is provided with a rotary joint. The air outlet pipe is connected to a hot air input pipe through the rotary joint, and the liquid outlet pipe is connected to an input pipe through the rotary joint. Cleaning liquid and rinsing liquid can be input into the two ends of the input pipe, respectively. Valves are provided at both ends of the input pipe.

[0010] Preferred technical solution 2: A protective cover is provided on one side of each of the two short plates. A second motor is fixedly connected to the surface of each of the two protective covers. The output ends of the two second motors extend into the interior of the connected protective covers and are fixedly connected to a drive gear. Driven gears are sleeved on the surface of the air outlet pipe and the liquid outlet pipe. The two drive gears mesh with the two driven gears respectively. The protective cover does not affect the rotation of the air outlet pipe and the liquid outlet pipe.

[0011] Preferred technical solution 3: A horizontal plate is fixedly connected to one side of the connecting plate, and two threaded holes are opened on the upper surface of the horizontal plate. Two sets of threaded holes are opened on the upper surface of the workbench. The horizontal plate can be fixedly installed on the workbench by bolts.

[0012] Preferred technical solution four: A liquid storage tank is fixedly installed on the lower surface of the workbench, and multiple through holes are opened on the upper surface of the workbench.

[0013] Preferred technical solution five: The upper surfaces of the two placement platforms are provided with placement slots, and a support frame is fixedly connected between the upper surfaces of the two placement platforms. A set of electric push rods is fixedly connected to the upper surface of the support frame, and the output ends of the set of electric push rods extend to the bottom of the support frame and are fixedly connected to pressure plates.

[0014] Compared with existing technologies, this utility model provides a cleaning device with the following advantages: In use, the cylinder to be cleaned is placed on two platforms. Then, the extension of an electric push rod drives a pressure plate to press and fix the cylinder. The rotation of a first motor drives a screw, which in turn moves the support plate and the cylinder, allowing the outlet pipe to be inserted into the cylinder. Simultaneously, cleaning fluid is introduced into the outlet pipe through an input pipe. Simultaneously, the rotation of a second motor drives the outlet pipe to rotate, causing the cleaning fluid inside the outlet pipe to be sprayed onto the inner wall of the cylinder through an outlet nozzle. The rotation of the brush bristles further cleans the inner wall of the cylinder. As the cylinder moves, it can be thoroughly cleaned. After cleaning is complete, the cleaning fluid supply to the input pipe is turned off. The system opens the valve for the flushing fluid input. The first motor then rotates in the reverse direction, returning the cylinder to its initial position. Simultaneously, the flushing fluid rinses the inside of the cylinder, removing any residual cleaning fluid and wastewater. After rinsing, the two valves on the input pipe are closed, stopping the corresponding second motor. The bolts are then loosened to release the locking mechanism of the connecting plate. The connecting plate is then moved to align the air outlet pipe with the cylinder. The first motor then rotates, moving the cylinder to insert the air outlet pipe. Simultaneously, hot air is introduced into the air outlet pipe and sprayed out through the nozzles to dry the cleaned cylinder. This convenient and quick system allows for rapid fixing and cleaning of the cylinder, followed by rapid drying for easy use. Attached Figure Description

[0021] Two slide grooves 9 are provided on the upper surface of the workbench 1. A slider 10 is slidably installed inside the two slide grooves 9. A connecting plate 11 is fixedly connected between the upper surfaces of the two sliders 10. Two short plates 12 are fixedly connected to the upper surface of the connecting plate 11. A liquid outlet pipe 13 is rotatably installed on the surface of one of the short plates 12, and an air outlet pipe 14 is rotatably installed on the surface of the other short plate 12.

[0022] One end of the liquid outlet pipe 13 is connected to a ring of liquid outlet nozzles, and one end of the liquid outlet pipe 13 is fixed with a brush ring 15, which is provided with brush bristles. One end of the air outlet pipe 14 is connected to a ring of air outlet nozzles, and one end of the air outlet pipe 14 is provided with a water-absorbing sponge 16.

[0023] Example 2: The difference between this example and Example 1 is that one end of the air outlet pipe 14 and the liquid outlet pipe 13 extends to the outside of the connected short plate 12 and is provided with a rotary joint 17. The air outlet pipe 14 is connected to a hot air input pipe through the rotary joint 17, and the liquid outlet pipe 13 is connected to an input pipe 18 through the rotary joint 17. Cleaning liquid and rinsing liquid can be input into the two ends of the input pipe 18, respectively, and valves are provided at both ends of the input pipe 18.

[0024] Example 3: The difference between this example and Example 1 is that, in this example, a protective cover 20 is provided on one side of each of the two short plates 12, and a second motor 21 is fixedly connected to the surface of each of the two protective covers 20. The output ends of the two second motors 21 extend into the interior of the connected protective covers 20 and are fixedly connected to a drive gear 22. Driven gears 23 are sleeved on the surface of the air outlet pipe 14 and the liquid outlet pipe 13. The two drive gears 22 mesh with the two driven gears 23 respectively. The protective cover 20 does not affect the rotation of the air outlet pipe 14 and the liquid outlet pipe 13.

[0025] Example 4: The difference between this example and Example 1 is that a horizontal plate 24 is fixedly connected to one side of the connecting plate 11. Two threaded holes are opened on the upper surface of the horizontal plate 24. Two sets of threaded holes are opened on the upper surface of the workbench 1. The horizontal plate 24 can be fixedly installed on the workbench 1 by bolts.

[0026] Example 5: The difference between this example and Example 1 is that a liquid storage tank 25 is fixedly installed on the lower surface of the workbench 1, and multiple through holes are opened on the upper surface of the workbench 1.

[0028] In summary, when using this cleaning equipment, the cylinder to be cleaned is placed on two placement platforms 8. Then, the extension of the electric push rod 27 drives the pressure plate 28 to press and fix the cylinder. The rotation of the first motor 19 drives the screw 2, thereby moving the support plate 7 and the cylinder, allowing the outlet pipe 13 to be inserted into the cylinder. Simultaneously, cleaning fluid is introduced into the outlet pipe 13 through the input pipe 18. The rotation of the second motor 21 drives the outlet pipe 13 to rotate, causing the cleaning fluid inside the outlet pipe 13 to be sprayed onto the inner wall of the cylinder through the outlet nozzle. The rotation of the brush bristles also scrubs the inner wall of the cylinder. As the cylinder moves, it can be thoroughly cleaned. After cleaning, the cleaning fluid input valve on the input pipe 18 is closed. Open the flushing fluid inlet valve, then the first motor 19 rotates in reverse to drive the cylinder back to its initial position. Simultaneously, the flushing fluid rinses the inside of the cylinder, removing residual cleaning fluid and wastewater. After rinsing, close the two valves on the inlet pipe 18, and the corresponding second motor 21 stops rotating. Then, loosen the bolts to release the lock on the connecting plate 11, and move the connecting plate 11 to align the outlet pipe 14 with the cylinder. The first motor 19 then rotates to move the cylinder, inserting the outlet pipe 14 into it. Simultaneously, hot air is introduced into the outlet pipe 14, and the hot air is sprayed out through the air nozzle to dry the cleaned cylinder. This is convenient and quick. This equipment can quickly fix and clean the cylinder, and can also quickly dry it after cleaning, making it easy to use.
