Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, in particular to a stable hydraulic cylinder. Background Art

[0002] A hydraulic cylinder is a hydraulic actuator that can achieve linear reciprocating motion. It has the advantages of simple structure, smooth movement and high working reliability. It is widely used in various occasions. Traditional hydraulic cylinders can be divided into piston type, plunger type and telescopic type.

[0003] Traditional hydraulic cylinders often lack effective protection against pressure loss. When pressure loss occurs during operation, the output of the hydraulic cylinder rapidly drops, causing a significant impact on the hydraulic cylinder itself and the equipment connected to it. In areas such as construction machinery and automated production lines, this impact can damage equipment components, such as rupturing hydraulic lines and loosening connections, thereby affecting the normal operation of the entire system and increasing equipment maintenance costs and downtime. Current hydraulic cylinders are prone to dust and impurities accumulating on their outer walls over long periods of use. These impurities adhere to the outer walls, and due to lack of cleaning, these deposits can gradually enter the cylinder, affecting its operation. Utility Model Content

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a stable hydraulic cylinder, comprising: a base; a hydraulic cylinder body, the bottom end of the hydraulic cylinder body is fixedly connected to the outer wall of the base; a driving motor, the driving motor is fixedly connected to the outer wall of the hydraulic cylinder body through a frame; a toggle gear, the outer wall of the toggle gear is fixedly connected to the output end of the driving motor; a cleaning mechanism, the cleaning mechanism is arranged on the outside of the hydraulic cylinder body; a buffer mechanism, the bottom end of the buffer mechanism is fixedly connected to the outer wall of the base; the buffer mechanism includes a vent pipe, the outer wall of the vent pipe is symmetrically fixedly connected to an air collecting cylinder, the inner wall of the air collecting cylinder is slidably connected to a piston rod, the top end of the piston rod is fixedly connected to a fixing ring, and the outer wall of the vent pipe is fixedly connected to a flow pipe.

[0005] Preferably, the outer wall of the vent tube is fixedly connected to the outer wall of the base, and the inner wall of the retaining ring is fixedly connected to the top end of the hydraulic cylinder body. Pressing the slider on the flow tube disengages the block from the air hole on the slider, allowing air to enter the vent tube through the flow tube, allowing air to circulate, thereby causing the output end of the hydraulic cylinder body to drive the retaining ring upward, driving the piston rod to slide within the air collecting cylinder, and drawing air into the air collecting cylinder.

[0006] Preferably, a push spring is fixedly connected to the inner wall of the circulation tube via a spring seat, a slider is slidably connected to the inner wall of the circulation tube, an air hole is formed in the wall of the slider, and a blocking block is fixedly connected to the inner wall of the circulation tube. The outer wall of the circulation tube is fixedly connected to the outer wall of the vent tube, the outer wall of the push spring is fixedly connected to the outer wall of the slider, and the outer wall of the blocking block is slidably connected to the inner wall of the air hole. When the hydraulic cylinder body is supported and no longer moves, the slider is released, and the action of air pressure and the push spring causes the slider to move back to its original position, causing the blocking block to re-enter the air hole, preventing air from being discharged from the circulation tube.

[0007] Preferably, the cleaning mechanism includes a rotating ring, the outer wall of the rotating ring is fixedly connected to an outer gear ring, the inner wall of the rotating ring is rotatably connected to a rotating rod, the bottom end of the rotating rod is fixedly connected to a driving gear, the outer wall of the rotating rod is fixedly connected to a cleaning brush, and the bottom end of the rotating ring is rotatably connected to an inner gear ring.

[0008] Preferably, the inner wall of the rotating ring is rotatably connected to the outer wall of the hydraulic cylinder body, the inner wall of the inner gear ring is fixedly connected to the outer wall of the hydraulic cylinder body, the driving gear is meshed with the inner gear ring, and the outer gear ring is meshed with the shifting gear. The driving gear is meshed with the inner gear ring, so that the rotating rod rotates about its own axis simultaneously with the rotation of the rotating ring.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The present invention provides a buffer mechanism to prevent air from being discharged from the circulation pipe. This design ensures that the gas in the buffer mechanism is in a stable state in the supporting state, further enhancing the stability of the hydraulic cylinder during the supporting process and preventing unstable support caused by gas leakage and other reasons. When the hydraulic cylinder body loses pressure during operation, the piston rod slides downward in the gas collecting cylinder to squeeze the air, which can slow down the speed of pressure loss at the output end of the hydraulic cylinder body. This function effectively protects the hydraulic cylinder and the equipment connected to it, avoiding equipment impact and damage caused by excessive pressure loss, thereby improving the safety and reliability of the entire system.

[0011] 2. This utility model incorporates a cleaning mechanism, driven by a motor. The cleaning brush cleans the outer wall of the hydraulic cylinder body as the rotating rod rotates and spins. This automatic cleaning function effectively removes dust and impurities from the outer wall of the hydraulic cylinder body, keeping the cylinder body clean. Maintaining a clean hydraulic cylinder body prevents dust and impurities from entering the cylinder, reducing the possibility of wear and corrosion, and thus extending the service life of the hydraulic cylinder.

[0020] The outer wall of the vent pipe 24 is fixedly connected to the outer wall of the base 5 , and the inner wall of the fixing ring 23 is fixedly connected to the top end of the hydraulic cylinder body 1 .

[0021] The inner wall of the circulation tube 25 is fixedly connected to a push spring 26 through a spring seat. The inner wall of the circulation tube 25 is slidably connected to a slider 27. An air hole 29 is opened in the wall of the slider 27. The inner wall of the circulation tube 25 is fixedly connected to a blocking block 28.

[0022] The outer wall of the circulation pipe 25 is fixedly connected to the outer wall of the ventilation pipe 24 , the outer wall of the push spring 26 is fixedly connected to the outer wall of the slider 27 , and the outer wall of the blocking block 28 is slidably connected to the inner wall of the air hole 29 .

[0023] The cleaning mechanism 3 includes a rotating ring 31, the outer wall of the rotating ring 31 is fixedly connected to an outer gear ring 36, the inner wall of the rotating ring 31 is rotatably connected to a rotating rod 33, the bottom end of the rotating rod 33 is fixedly connected to a driving gear 34, the outer wall of the rotating rod 33 is fixedly connected to a cleaning brush 35, and the bottom end of the rotating ring 31 is rotatably connected to an inner gear ring 32.

[0024] The inner wall of the rotating ring 31 is rotatably connected to the outer wall of the hydraulic cylinder body 1 , the inner wall of the inner gear ring 32 is fixedly connected to the outer wall of the hydraulic cylinder body 1 , the driving gear 34 is meshed with the inner gear ring 32 , and the outer gear ring 36 is meshed with the shifting gear 6 .

[0025] Working principle:

[0026] When the hydraulic cylinder body 1 on the base 5 is used again, the output end of the hydraulic cylinder body 1 moves upward. At this time, the slider 27 on the circulation pipe 25 is pressed through the buffer mechanism 2, so that the block 28 is separated from the air hole 29 on the slider 27. At this time, air can enter the vent pipe 24 through the circulation pipe 25, allowing air to circulate, so that the output end of the hydraulic cylinder body 1 drives the fixing ring 23 to move upward, and drives the piston rod 22 to slide in the air collecting cylinder 21, and draws air into the air collecting cylinder 21. When the hydraulic cylinder body 1 is supported and no longer moves, the slider 27 is released, and then the spring 26 is pushed to move the slider 27 back to its original position, so that the block 28 enters the air hole 29 again, so that the air cannot be discharged from the circulation pipe 25.

[0027] When the hydraulic cylinder body 1 loses pressure during operation, the output end of the hydraulic cylinder body 1 moves downward. At this time, the fixing ring 23 moves downward with the output end of the hydraulic cylinder body 1, driving the piston rod 22 to slide downward in the air collecting cylinder 21, so that the piston rod 22 squeezes the air in the air collecting cylinder 21, slowing down the speed at which the output end of the hydraulic cylinder body 1 loses pressure.

[0028] During daily use, the driving motor 4 drives the toggle gear 6 to rotate. Since the outer gear ring 36 is engaged with the toggle gear 6, the rotation of the toggle gear 6 will drive the outer gear ring 36 to rotate, thereby causing the rotating ring 31 to rotate on the outer wall of the hydraulic cylinder body 1. When the rotating ring 31 rotates, the rotating rod 33 is also driven to rotate. Because the bottom end of the rotating rod 33 is fixedly connected to the driving gear 34, and the driving gear 34 is engaged with the inner gear ring 32, the rotating rod 33 will also rotate around its own axis while the rotating ring 31 rotates. The cleaning brush 35 cleans the outer wall of the hydraulic cylinder body 1 as the rotating rod 33 rotates and rotates.
