Description

Technical Field

[0001] The invention relates to the technical field of hydraulic cylinders, and in particular to a high-pressure and high-flow hydraulic cylinder. Background Art

[0002] Hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy and perform linear reciprocating motion (or swinging motion). Hydraulic cylinders are widely used in machinery and equipment in various fields. In the process of using hydraulic cylinders, since the piston rod in the hydraulic cylinder contacts the outside air when it extends out of the cylinder body, when the external working conditions are bad, dust in the air and splashing liquid or solids caused by other actuators during the working process are easy to splash onto the hydraulic cylinder and the piston rod, causing foreign matter to adhere to the surface of the piston rod. The adhered foreign matter combines with the lubrication on the piston rod to form oil stains that interfere with the operation of the piston rod, causing the piston rod to run unsmoothly. At the same time, the splashing liquid or solid is also easy to damage the cylinder;

[0003] When the temperature is low, hydraulic oil is easy to condense, which is not conducive to the transportation of hydraulic oil. At the same time, when hydraulic oil flows, it is easy to mix with impurities and waste chips generated by the cylinder and the oil pump. In serious cases, the equipment is damaged.

[0044] A cleaning window 510 is provided on one side of the box body 51 , and a cover plate 211 is fixed to the opening of the cleaning window 510 by screws. The second spray hole 75 is inclined along the support mechanism 53 toward the filter cartridge 52 .

[0045] Embodiment 3:

[0046] The rear end plugging component 2 includes a U-shaped structured substrate 21, and an end plate 22 fixedly connected to the adjacent connecting seat 11 is fixedly connected to the side of the substrate 21 away from the opening toward the front end plugging component 3. A receiving tube 23 is fixedly sleeved on the end plate 22. A heat insulation layer 1 is installed on the substrate 21 and the end plate 22. An auxiliary heating tube is fixedly connected to the inner wall of the substrate 21. The outer circle of the receiving tube 23 is covered with a heat insulation sleeve. The oil pipe 2 42 is received inside the receiving tube 23 to isolate and insulate the oil pipe 2 42.

[0047] The front end blocking component 3 includes a movable cover 31 slidably sleeved on the outside of the rear end blocking component 2 , the movable cover 31 is penetrated by an insertion hole 32 coaxially arranged with the connecting rod 14 , and the inner wall of the cover 31 is fixedly connected to the second insulation layer.

[0048] The end of the box body 51 away from the oil pipe 1 15 is fixedly connected to the oil pipe 2 42 , the bottom of the box body 51 is fixedly connected to a supporting plate 43 with an arc structure, and the bottom of the supporting plate 43 is fixedly connected to a fixing plate 44 fixedly connected to the adjacent connecting seat 11 .

[0049] The connection seat 11 is penetrated by a mounting hole for fixing, and sealing strips are installed at the bottom of the rear end blocking component 2 and the front end blocking component 3.

[0050] The front end of the piston rod 13 is provided with a sealing ring which is coaxially arranged therewith and contacts with the inner wall of the front end blocking component 3, and the connecting rod 14 is provided with an external thread for fixing.

[0051] Working principle: During installation, the fixing bolts are passed through the mounting holes reserved on the two sets of connecting seats 11 and then threadedly connected to the parts used to fix the oil cylinder 1, and the filter auxiliary heat component 4 is connected to the oil pipe 15 and connected to the connecting seat 11 through the support plate 43 and the fixing plate 44. After that, the rear end plugging component 2 is pushed forward from the end of the oil cylinder 1 and fixed to the connecting seat 11, and the front end plugging component 3 is pushed from the front end of the oil cylinder 1 to the rear end plugging component 2, so that the front end plugging component 3 is in contact between the connecting rod 14 and the piston rod 13. When the connecting rod 14 is connected to the working part at the front end of the oil cylinder 1, the working part and the piston rod 13 clamp and fix the front end plugging component 3, and at the same time, the bottoms of the front end plugging component 3 and the rear end plugging component 2 are in contact with the surface of the component used to fix the oil cylinder 1. When the oil cylinder 1 is working, the front end plugging component 3 and the rear end plugging component 2 cover the oil cylinder 1 and the piston rod 13 inside, so as to achieve the heat preservation and foreign matter and dust isolation operation of the oil cylinder 1, and use the auxiliary heat filtering component 4 to filter and heat the power medium of the oil cylinder 1;

[0052] Since the piston rod 13 of the oil cylinder 1 is always located in the cavity formed by the front end blocking component 3 and the rear end blocking component 2 during telescopic operation, the piston rod 13 is isolated from the outside world, and foreign matter such as dust and moisture in the outside air can be isolated. At the same time, the oil cylinder 1 is also protected and isolated to prevent splashing solid and liquid substances from adhering to and colliding with the oil cylinder 1;

[0053] When filtering and heating the power medium, when the hydraulic oil from the oil pump enters the oil pipe 15 along the oil pipe 2 42 along the filtering auxiliary heating component 4, since the pressure at one end of the oil pipe 2 42 is higher than the pressure of the oil pipe 15, when the hydraulic oil enters the box body 51, the hydraulic oil enters the inside of the blocking tube 72 of the support mechanism 53, and the adjustment mechanism 55 moves to the side away from the oil pipe 2 42 under the pressure of the hydraulic oil. At this time, the driven plate 81 moves toward the side of the support plate 71 until the closing plate 84 on the limiting tube 2 83 conflicts with the support plate 71. At this time, the closing plate 84 blocks the spray hole 3 77 on the support plate 71, and the blocking rod 78 also extends into the channel 82 on the driven plate 81 to block the channel 82, and then the moving driven plate 81 moves to the spray hole 1 74 When the driven disc 81 moves on one side, the spray hole 1 74 is not blocked. At this time, the hydraulic oil can only flow along the spray hole 1 74 and the spray hole 2 75 on the blocking tube 72 to the outer ring of the blocking tube 72. At the same time, the adjustment mechanism 55 at one end adjacent to the oil pipe 15 moves toward the direction of the oil pipe 15 under the action of the connecting rod 54. At this time, the adjustment mechanism 55 adjacent to the oil pipe 15 blocks the spray hole 1 74 on the supporting mechanism 53, while the spray hole 3 77 on the supporting disc 71 and the channel 82 on the driven disc 81 are both opened, so that the hydraulic oil at one end adjacent to the oil pipe 15 can only flow from the inside of the filter cartridge 52 along the spray hole 3 77 on the supporting mechanism 53 and the channel 82 of the adjustment mechanism 55 into the oil pipe 15, thereby realizing the filtering operation of the process of the hydraulic oil entering the oil cylinder 1;

[0054] When the hydraulic oil sprayed from the second spray hole 75 pushes the blades on the cleaning mechanism 57, the rotating tube 61 rotates, so that the scraper 62 cleans the foreign matter and the agglomerated oil stains adhering to the outer ring of the filter cylinder 52;

[0055] When the hydraulic oil is discharged from the oil cylinder 1, in order to discharge the hydraulic oil smoothly, the hydraulic oil pressure at one end of the oil pipe 15 must be greater than the pressure at one end of the oil pipe 2 42. Therefore, the same principle as above is used to drive the adjustment mechanism 55 to move, thereby realizing the state switching of the filtering auxiliary heating mechanism 4, completing the filtering operation during the hydraulic oil discharge from the oil cylinder 1, and at the same time using the heating pipe 59 to perform auxiliary heating on the hydraulic oil, so as to facilitate the smooth movement of the hydraulic oil, avoid the hydraulic oil cooling and solidification blockage in the external low temperature environment, and avoid the cylinder from jamming during operation;

[0056] The present invention adopts an isolation component formed on the outside of the oil cylinder and adjusted with the movement of the piston rod, so as to cover and isolate the oil cylinder body and the piston rod from the outside world, thereby realizing the heat preservation and foreign matter and dust isolation operation of the oil cylinder. The piston rod is isolated from the outside world, and foreign matters such as dust and moisture in the outside air can be isolated. The oil cylinder is also protected and isolated to avoid the adhesion and collision of splashing solid and liquid substances, thereby protecting the safety of the oil cylinder. When the oil cylinder is running, the state of the filtering and auxiliary heating components is automatically adjusted by utilizing the oil pressure difference of the hydraulic oil in the process of entering and exiting the oil cylinder, thereby realizing the filtering and auxiliary heating operations in the process of the hydraulic oil entering and exiting, facilitating the smooth movement of the hydraulic oil, avoiding the cooling and solidification blockage of the hydraulic oil in the low temperature environment, and avoiding the jamming of the oil cylinder during operation.

[0057] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
