Description

Technical Field

[0001] The utility model relates to the technical field of valve core cleaning, in particular to a hydraulic valve core cleaning device. Background Art

[0002] After the hydraulic valve core has been used for a period of time, the hydraulic oil contamination may cause oil deposition, or the granular impurities in the hydraulic oil may cause the hydraulic valve to malfunction. In this case, the valve core and other parts need to be disassembled and cleaned using hydraulic valve core cleaning equipment.

[0003] For example, in the prior art, the patent application with the authorization publication number CN219723905U and the authorization publication date 2023-09-22 and the name of "Hydraulic Valve Spool Cleaning Device" is provided with a pushing device, which pushes the hanging basket to rotate in and out of the cleaning box, avoiding the need to put the hand into the cleaning liquid to place the hanging basket, and a number of air pipes are provided on both sides of the cleaning box. When the hanging basket enters the cleaning box, the bubbles sprayed from both sides of the cleaning box can clean the valve core, and the pushing device can also drive the hanging basket to move in the cleaning box, so that the hanging basket is close to the air pipe. The closer to the air pipe on one side of the cleaning box, the better the cleaning effect on the corresponding side of the valve core, and both sides of the valve core can be cleaned, without any cleaning dead angles;

[0004] During the actual use of the above-mentioned device, after the valve core is placed in the cleaning box through the hanging basket, if the air pressure in the air pipe is low, it will be in a stationary state, and the valve core will not be easily cleaned in all directions. In addition, the air pipe is fixedly connected to the side of the cleaning box, resulting in a smaller coverage area of ​​the sprayed gas during operation, which also affects the uniform cleaning effect of the valve core.

[0005] Therefore, we propose a hydraulic valve core cleaning device to solve the above problems. Utility Model Content

[0036] Combination Figure 1-4 As shown, the valve core is placed above the partition 71 and placed in the cleaning box 1, and the motor 13 is started. The motor 13 drives the reciprocating screw rod 14 to rotate. When the reciprocating screw rod 14 rotates, the rack 15 threadedly sleeved on the outside of the reciprocating screw rod 14 can move forward and backward inside the cleaning box 1 by virtue of the fit between the rack 15 and the cleaning box 1. During the forward and backward movement of the rack 15, the gear 12 and the jet pipe 10 where the gear 12 is located can be driven to rotate forward and backward by virtue of the meshing action between the rack 15 and the gear 12. Then, when the jet pipe 10 is connected to the existing air compressor through the air injection pipe 11, when the existing air compressor is started, the gas is discharged through the jet pipe 10 to flush the valve core.

[0038] Combination Figure 3-5 As shown, when the reciprocating screw rod 14 drives the rack 15 to move forward and backward, the rack 15 can drive the first inclined block 162 to move through the frame 161. When the first inclined block 162 moves forward and backward, the first inclined block 162 can use the fitting effect with the second inclined block 72 to prompt the inner frame 7 connected to the upper end of the second inclined block 72 to move upward inside the outer frame 5, and then the inner frame 7 moves downward under the action of its own gravity. The valve core placed inside the inner frame 7 is displaced during the up and down movement, thereby facilitating the gas ejected from the jet pipe 10 to clean the valve core in all aspects, further improving the cleaning effect.

[0039] Working principle: When using the hydraulic valve core cleaning equipment, Figure 1-5 As shown, first connect the air injection pipe 11 to the existing air compressor, then place the valve core on the partition 71, then start the electric push rod 2, drive the outer frame 5 to move down into the cleaning box 1, and drive the side plate 6 to flip during the movement, so that the valve core can be prevented from falling outside the outer frame 5 for subsequent retrieval, and then start the motor 13 and the air compressor. The motor 13 drives the rack 15 to move forward and backward through the reciprocating screw 14. During the forward and backward movement of the rack 15, the gear 12 and the injection pipe 10 where the gear 12 is located are driven to rotate forward and backward. When the existing air compressor is started The gas is discharged through the jet pipe 10 to flush the valve core. Since the jet pipe 10 expands the jet range through reciprocating swing, the cleaning range is improved and the cleaning effect is enhanced. When the reciprocating screw rod 14 drives the rack 15 to move forward and backward, the first inclined block 162 and the second inclined block 72 are used to cooperate to drive the inner frame 7 to move upward, and then the inner frame 7 moves downward under the action of its own gravity. The valve core placed in the inner frame 7 is displaced during the up and down movement, so that the gas sprayed from the jet pipe 10 can clean the valve core in all aspects, further improving the cleaning effect.
