Description

Technical Field

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

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It is widely used in machinery and equipment in various fields. During the use of the hydraulic cylinder, since the piston rod in the hydraulic cylinder comes into contact with the outside air when extending from the cylinder body, when the external working environment is harsh, dust in the air and splashing liquid or solids caused by other actuators during operation can easily splash onto the hydraulic cylinder and 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 solids can easily 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 the hydraulic oil flows, it is easy to mix with impurities and waste generated by the cylinder and the oil pump. In serious cases, the equipment is damaged. Therefore, a high-pressure and high-flow hydraulic cylinder is proposed. Summary of the Invention

[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 tilted along the support mechanism 53 toward the filter cartridge 52 .

[0045] Example 3

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

[0047] The front end blocking assembly 3 includes a movable cover 31 that is slidably sleeved on the outside of the rear end blocking assembly 2. The movable cover 31 is penetrated by an insertion hole 32 that is coaxially arranged with the connecting rod 14. The inner side wall of the movable 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 fixed to the adjacent connecting seat 11 .

[0049] The connecting 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 the inner side wall of the front end blocking component 3 , and the connecting rod 14 is provided with an external thread for fixation.

[0051] Working principle: During installation, the bolts used for fixing 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 blocking component 2 is pushed forward from the end of the oil cylinder 1 and fixed to the connecting seat 11, and the front end blocking component 3 is pushed from the front end of the oil cylinder 1 to the rear end blocking component 2, so that the front end blocking 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 component at the front end of the oil cylinder 1, the working component and the piston rod 13 clamp and fix the front end blocking component 3. At the same time, the bottoms of the front end blocking component 3 and the rear end blocking 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 blocking component 3 and the rear end blocking component 2 cover the oil cylinder 1 and the piston rod 13 inside, thereby achieving heat preservation and foreign matter and dust isolation operations for the oil cylinder 1, and utilizing the auxiliary heat filtering component 4 to perform filtering and auxiliary heat operations on 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 can isolate foreign matter such as dust and moisture in the outside air. At the same time, it also protects and isolates the oil cylinder 1 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 flows along the oil pipe 2 42 along the filtering auxiliary heating component 4 into the oil pipe 1 15, since the pressure at one end of the oil pipe 2 42 is higher than the pressure at the oil pipe 1 15, at this time, 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 under the pressure of the hydraulic oil, the adjustment mechanism 55 moves to the side away from the oil pipe 2 42. At this time, the driven disc 81 moves toward the side of the support disc 71 until the closing plate 84 on the limiting tube 2 83 contacts the support disc 71. At this time, the closing plate 84 blocks the spray hole 3 77 on the support disc 71, and the blocking rod 78 also extends into the channel 82 on the driven disc 81 to block the channel 82. Then the moving driven disc 81 moves toward the spray hole 1 74 When one side moves, the driven disc 81 does not block the spray hole 1 74. 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 the end adjacent to the oil pipe 15 moves toward 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 support mechanism 53, while the spray hole 3 77 on the support disc 71 and the channel 82 on the driven disc 81 are both open, so that the hydraulic oil at the 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 support mechanism 53 and the channel 82 of the adjustment mechanism 55 and finally into the oil pipe 15, thereby achieving a filtering operation 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 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 ensure smooth discharge of the hydraulic oil, 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 process of the hydraulic oil being discharged from the oil cylinder 1. At the same time, the heating pipe 59 is used 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 occurrence of jamming of the oil cylinder 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 to cover and isolate the oil cylinder body and the piston rod from the outside world, thereby realizing heat preservation and foreign matter and dust isolation operations of the oil cylinder. The piston rod is isolated from the outside world, and can isolate foreign matter such as dust and moisture in the outside air, and also protect the oil cylinder to avoid adhesion and collision of splashing solid and liquid substances, thereby protecting the oil cylinder safety; when the oil cylinder is running, the oil pressure difference of the hydraulic oil in the process of entering and exiting the oil cylinder is used to automatically adjust the state of the filtering and auxiliary heating components, thereby realizing filtering and auxiliary heating operations during the process of hydraulic oil entering and exiting, facilitating smooth movement of the hydraulic oil, avoiding the occurrence of hydraulic oil cooling, solidification and blockage in the external low temperature environment, and avoiding the occurrence of jamming of the oil cylinder during operation.

[0057] The above 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 replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
