Description

TECHNICAL FIELD

[0002] The hydraulic oil cylinder is a hydraulic execution element for converting hydraulic energy into mechanical energy and performing linear reciprocating motion or oscillating motion. When the hydraulic oil cylinder is used to realize reciprocating motion, a speed reduction device can be omitted, and there is no transmission gap, so the motion is stable. Therefore, the hydraulic oil cylinder is widely used in various hydraulic systems. The hydraulic oil cylinder basically consists of a cylinder barrel and a cylinder cover, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

[0003] The pressure test detection of the hydraulic oil cylinder is mainly to detect the sealing property of the oil cylinder by applying pressure.

However, after the existing hydraulic oil cylinder pressure test detection device detects the hydraulic oil cylinder with unqualified sealing property, the leaked hydraulic oil on the hydraulic oil cylinder cannot be cleaned in time, which causes environmental pollution and safety hazards.

[0072] The working principle and use flow of the embodiment of the present application are as follows:

[0073] In the initial state, the sliding plate 49 is located at the middle position of the electric sliding rail 48, the lower surface of the moving plate 418 is tightly attached to the top of the U-shaped block 51, the magnetic plate two 421 is in contact with the magnetic plate four 56, the upper surface of the push plate three 416 is tightly attached to the lower surface of the moving plate 418, the magnetic plate one 420 is in contact with the magnetic plate three 422, the spring one 417 is still in the compressed state, the ball one 423 is located at the side of the circular ring plate two 55 away from the L-shaped plate 53 and is in contact with the outer circumferential surface of the circular ring plate two 55, the spring two 52 is compressed, the telescopic rod two 54 is shortened to the shortest, the clamping block 61 is farthest from the hydraulic oil cylinder 10, the clamping plate 68 is tightly attached to the clamping block 61 to clamp the adsorption block 24, the adsorption block 24 cannot touch the extension point of the piston rod 12, the straight rod one 96 and the straight rod two 910 are both in the vertical state, the spring three 63 is still in the compressed state, the push plate two 71 is tightly attached to the fixed block 81, the magnetic plate six 78 is in contact with the magnetic plate seven 84, the lower plate 73 cannot be directly below the clamping block 61 and the clamping plate 68, the movable plate 64 is in contact with the inner side wall one 75, the through slot two 79 and the bottom opening of the installation pipe 23 cannot be in communication with each other, the two liquid injection plates 915 are located at the side of the hydraulic oil cylinder 10 away from the vertical plate 21 (so that when the extension point of the piston rod 12 leaks hydraulic oil, the hydraulic oil cannot be sprayed or dripped on the liquid injection plate 915), the camera 33 monitors whether the extension point of the piston rod 12 leaks hydraulic oil outwardly;

[0074] Then start the hydraulic cylinder 10 makes piston rod 12 full stroke reciprocating several times, if the piston rod 12 of the extension point of hydraulic oil leakage, camera 33 will be transmitted to the controller video information of hydraulic oil leakage, the staff will shut down the hydraulic cylinder 10 of this oil leakage, then the oil leakage of hydraulic cylinder 10 is removed for processing, in the process of removing the oil leakage of hydraulic cylinder 10, if not clean up the hydraulic cylinder 10 on the outside of the leakage of hydraulic oil, the staff will be easy to stick on the hydraulic oil, so the staff will start the electric slide rail 48 before removing the oil leakage of hydraulic cylinder 10, the electric slide rail 48 drives the slide plate 49 from the middle of the electric slide rail 48 to move up to the highest, in the process of slide plate 49 will drive the pusher plate three 416 to move up, the pusher plate three 416 pushes the moving plate 418 to move up, the moving plate 418 moves up will further compress the spring one 417, in turn makes the telescopic rod one 419 shortens, in turn makes the ball one 423 moves to the upper of the ring plate two 55, in turn makes the L-shaped plate 53 moves away from the U-shaped block 51 under the action of the spring two 52, in turn makes the telescopic rod two 54 to the longest, in turn makes the clamping block 61 moves to the direction of close to the hydraulic cylinder 10 (at this time the lower plate 73 still can't block in the middle of the clamping block 61 and the clamping plate 68), in turn makes the movable plate 64 and the inner side wall two 76 contact, in turn makes the adsorption block 24 close to the extension point of the piston rod 12, in turn makes the adsorption block 24 adsorbs the hydraulic oil leaked outside the extension point of the piston rod 12, realizes the cleaning of the hydraulic oil leaked outside the hydraulic cylinder 10 of the sealing failure, solves the existing hydraulic cylinder pressure detection device after detecting the sealing failure of the hydraulic cylinder, can't clean up the hydraulic oil leaked outside the hydraulic cylinder in time, causes the environmental pollution and the technical problem of the security hidden danger;

[0075] At the same time, the slide plate 49 moves up to the highest from the middle of the electric slide rail 48, in the process of the slide plate 49 drives the rack one 413 to move up, in the process of the rack one 413 moves up, the rack one 413 will mesh with the gear one 44, in turn makes the rack one 413 drive the gear one 44 rotates half a circle, in turn makes the shaft rod 43 rotates half a circle, in turn makes the fixed cylinder 42 rotates half a circle, in turn makes the hydraulic cylinder 10 rotates half a circle, in turn makes the extension point of the piston rod 12 can fully contact with the adsorption block 24, in turn makes the adsorption block 24 can fully adsorb the leakage of hydraulic oil, at the same time, the rotation of the hydraulic cylinder 10 also will make the adsorption block 24 and the surface of the cylinder 11, piston rod 12 produce friction, accelerate the adsorption block 24 adsorbs the leakage of hydraulic oil, improves the efficiency of the adsorption block 24 adsorbs the hydraulic oil;

[0076] When the sliding plate 49 is at the highest point, the controller drives the electric sliding rail 48 to drive the sliding plate 49 to move downward, so that the sliding plate 49 is reset (the sliding plate 49 moves to the middle position of the electric sliding rail 48), and then the rotating shaft rod 43 is rotated and reset, and then the fixed cylinder 42 is rotated and reset. During the resetting process of the sliding plate 49, the sliding plate 49 drives the push plate three 416 to move downward. At this time, due to the tension of the spring one 417 and the magnetic attraction between the magnetic plate one 420 and the magnetic plate three 422, the push plate three 416 and the moving plate 418 are firmly combined into a whole, so that the push plate three 416 can firmly drive the moving plate 418 to move downward, and then the moving plate 418 can be reset, and then the ball one 423 can be reset, and then the clamping block 61 can be reset, and then the movable plate 64 is in contact with the inner side wall one 75, and then the adsorption block 24 is separated from the surface of the cylinder 11 and the piston rod 12, and then the adsorption block 24 is reset. The moving speed of the sliding plate 49 is controlled by the electric sliding rail 48, and then the time of the adsorption block 24 adsorbing the leaked hydraulic oil of the hydraulic oil cylinder 10 is controlled.

[0077] After the adsorption block 24 is reset (after the adsorption block 24 adsorbs the leaked hydraulic oil), some hydraulic oil and impurities will still remain at the extension point of the piston rod 12. If it is not cleaned in time, the longer the time is, the more difficult it is to clean the remaining hydraulic oil and impurities when the hydraulic oil cylinder 10 with unqualified sealing performance is maintained later. At the same time, the old adsorption block 24 needs to be replaced by a new adsorption block 24 after being used, and the old adsorption block 24 is stained with hydraulic oil. If the staff replaces it, the staff will be stained with hydraulic oil. Therefore, it is necessary to use cleaning fluid to clean the extension point of the piston rod 12 in time, and the old adsorption block 24 needs to be disposed of and replaced by a new adsorption block 24. Therefore, at this time, the electric sliding rail 48 is driven to drive the sliding plate 49 to move downward from the middle position of the electric sliding rail 48 to the lowest position, and then the sliding plate 49 moves upward from the lowest position to the middle position of the electric sliding rail 48 to realize resetting.

[0078] During the process that the sliding plate 49 moves downward from the middle position of the electric sliding rail 48 to the lowest position, the lower surface of the moving plate 418 is tightly attached to the top of the U-shaped block 51, the magnetic plate two 421 is in contact with the magnetic plate four 56, and then the U-shaped block 51 blocks the downward movement of the moving plate 418, so that the push plate three 416 cannot drive the moving plate 418 to continue to move downward. During the downward movement of the sliding plate 49, the sliding plate 49 drives the rack two 414 and the rack three 415 to move downward. During the downward movement of the rack two 414 and the rack three 415, the rack two 414 will first engage with the gear two 95. After the rack two 414 is separated from the gear two 95, the rack three 415 will engage with the gear three 99.

[0079] The rack two 414 moves downward and engages with the gear two 95, which can make the gear two 95 rotate clockwise, further make the rotating rod one 94 rotate clockwise, further make the straight rod one 96 rotate from vertical state to horizontal state, further make the ball two 97 push the push plate one 66 to move, further make the movable plate 64 move towards the clamping block 61, further make the movable plate 64 contact with the inner side wall two 76, further make the spring three 63 be compressed further, further make the telescopic rod three 65 shorten, further make the clamping plate 68 move away from the clamping block 61, further make the old adsorption block 24 fall off from the clamping plate 68 and the clamping block 61, realize the automatic disassembly of the old adsorption block 24, at the same time, the clockwise rotation of the rotating rod one 94 can drive the rotating rod three 912 rotate clockwise, further make the straight plate 913 rotate, further make the vertical part of the liquid injection pipe 914 rotate, further make the two liquid injection plates 915 rotate to the upper and lower sides of the extension point of the piston rod 12 (the extension point of the piston rod 12 is located in the middle of the two liquid injection plates 915), further make the cleaning liquid sprayed by the spray head 916 on the two liquid injection plates 915 be able to be completely sprayed on the extension point of the piston rod 12, improve the utilization rate of the cleaning liquid;

[0080] The rack three 415 moves downward and engages with the gear three 99, which can make the gear three 99 rotate clockwise, further make the rotating rod two 98 rotate clockwise, further make the straight rod two 910 rotate from vertical state to horizontal state, further make the ball three 911 push the push plate two 71, further make the push plate two 71 contact with the limiting plate 83, further make the magnetic plate five 77 contact with the magnetic plate eight 85, further make the lower plate 73 move to the position right below the clamping plate 68 and the clamping block 61, further make the movable plate 64 contact with the inner side wall one 75, further make the through slot two 79 and the bottom opening of the mounting pipe 23 be in communication with each other, further make the new adsorption block 24 inside the mounting pipe 23 be able to fall down to the position between the clamping plate 68 and the clamping block 61 (the upper end of the new adsorption block 24 between the clamping plate 68 and the clamping block 61 is inserted into the through slot two 79, and the top of the new adsorption block 24 between the clamping plate 68 and the clamping block 61 is coplanar with the upper surface of the upper plate 72), at the same time, the clockwise rotation of the rotating rod two 98 can make the ball valve rotate ninety degrees clockwise, further make the liquid inlet pipe 918 completely open, further make the cleaning liquid in the liquid inlet pipe 918 pass through the hose 917, the liquid injection pipe 914, the liquid injection plate 915 in sequence, and be sprayed on the extension point of the piston rod 12 by the spray head 916, clean the residual hydraulic oil and impurities at the connection between the cylinder barrel 11 and the piston rod 12, avoid the problem that the residual hydraulic oil and impurities on the hydraulic oil cylinder 10 with unqualified sealing performance are more difficult to clean later;

[0081] When the sliding plate 49 moves to the lowest position, the driving electric sliding rail 48 drives the sliding plate 49 to move upward from the lowest position to the middle of the driving electric sliding rail 48, so as to reset the sliding plate 49. In the process that the sliding plate 49 moves upward from the lowest position to the middle of the driving electric sliding rail 48, the sliding plate 49 drives the rack two 414 and the rack three 415 to move upward and reset. In the process that the rack two 414 and the rack three 415 move upward and reset, the rack three 415 is first engaged with the gear three 99, and then the rack two 414 is engaged with the gear two 95 after the rack three 415 is disengaged from the gear three 99;

[0082] In the process that the rack three 415 moves upward and resets, the rack three 415 is engaged with the gear three 99, so as to reverse the gear three 99, and then reverse the rotating rod two 98, and then make the straight rod two 910 rotate from the horizontal state to the vertical state. At this time, the push plate two 71 cannot move due to the contact between the magnetic plate five 77 and the magnetic plate eight 85, and the ball valve is reversely rotated by ninety degrees due to the reverse rotation of the rotating rod two 98, so as to completely close the liquid inlet pipe 918, and the cleaning liquid cannot be sprayed out of the nozzle 916;

[0083] In the process of the rack two 414 upwardly moving reset, the rack two 414 and the gear two 95 meshing, can make the gear two 95 reverse, in turn make the rotating rod one 94 reverse, in turn make the straight rod one 96 from horizontal state to vertical state, in turn make the ball two 97 reset, at this time due to the tension of the spring three 63 makes the movable plate 64 move away from the clamping block 61 direction, in turn make the telescopic rod three 65 elongation reset, in turn make the clamping plate 68 reset, in turn make the clamping plate 68 and clamping block 61 clamp new adsorption block 24, after using the adsorption block 24 with hydraulic oil, automatically replace the unused adsorption block 24, avoid staff in the replacement of adsorption block 24 with hydraulic oil, improve the reliability and safety of the device use. At the same time, the movable plate 64 away from the clamping block 61 direction will also drive the upper plate 72, the lower plate 73 move (because the movable plate 64 and the inner side wall one 75 contact at this time), in turn make the upper plate 72, the lower plate 73 reset (because the clamping plate 68 and clamping block 61 between the new adsorption block 24 is elastic, so in the process of the upper plate 72 reset, the movement of the upper plate 72 will bend the new adsorption block 24 between the clamping plate 68 and the clamping block 61, in turn make the new adsorption block 24 between the clamping plate 68 and the clamping block 61 will be close to the clamping block 61, in turn make the new adsorption block 24 between the clamping plate 68 and the clamping block 61 will be pulled out from the through slot two 79 after the upper plate 72 reset), in turn make the push plate two 71 reset, in turn make the push plate two 71 and fixed block 81 close, in turn make the magnetic plate six 78 and the magnetic plate seven 84 contact, in turn make the through slot two 79 and the bottom opening of the installation pipe 23 can not be communicated with each other, at the same time, the rotating rod one 94 reverse will drive the rotating rod three 912 reverse, in turn make the straight plate 913 reset, in turn make two liquid injection plate 915 reset.

[0084] In summary, by setting the detection main body 2, first fix the hydraulic cylinder 10 horizontally on the inside of the fixed cylinder 42, the lens of the camera 33 faces the extension point of the piston rod 12, the camera 33 monitors the sealing of the hydraulic cylinder 10 in real time and transmits the video information to the controller in the detection workbench 1, which is convenient for detecting the sealing of the hydraulic cylinder 10; by starting the hydraulic cylinder 10 to make the piston rod 12 reciprocate several times, when the extension point of the piston rod 12 has hydraulic oil leakage, by driving the electric sliding rail 48, the sliding plate 49 moves from the middle position of the electric sliding rail 48 to the highest position, and then the sliding plate 49 moves from the highest position to the middle position of the electric sliding rail 48 to reset, in this reciprocating process, the adsorption block 24 is tightly attached to the extension point of the piston rod 12, and then the adsorption block 24 adsorbs the hydraulic oil leaked outward from the extension point of the piston rod 12, realizes the cleaning of the hydraulic oil leaked outward from the hydraulic cylinder 10 with unqualified sealing, solves the technical problems that the existing hydraulic cylinder pressure test detection device cannot clean the hydraulic oil leaked outward from the hydraulic cylinder in time after detecting the hydraulic cylinder with unqualified sealing, causing environmental pollution and safety hazards; by driving the electric sliding rail 48, the sliding plate 49 moves from the middle position of the electric sliding rail 48 to the lowest position, and then the sliding plate 49 moves from the lowest position to the middle position of the electric sliding rail 48 to reset, in this reciprocating process, the cleaning liquid is sprayed on the extension point of the piston rod 12, the residual hydraulic oil and impurities at the connection between the cylinder barrel 11 and the piston rod 12 are removed, which avoids the problem that the residual hydraulic oil and impurities of the hydraulic cylinder 10 with unqualified sealing are more difficult to clean later, and the adsorption block 24 with hydraulic oil after use is automatically replaced with unused adsorption block 24, which avoids the staff from being stained with hydraulic oil when replacing the adsorption block 24, improves the reliability and safety of the device.
