Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a wear-resistant sealing hydraulic oil cylinder device. 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 has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. The hydraulic cylinder is basically composed of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device and an exhaust device.

[0003] At present, when the hydraulic cylinders on the market are in use, dust in the air will fall on the hydraulic cylinders and enter the hydraulic cylinders. The dust will not only make the hydraulic cylinders less wear-resistant, but also affect their own sealing effect, causing the hydraulic oil in the hydraulic cylinders to leak out. Therefore, a wear-resistant sealing hydraulic cylinder device is proposed. Utility Model Content

[0036] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0037] Please refer to Figures 1 to 6 As shown, the wear-resistant sealed hydraulic cylinder device of the present invention includes a cylinder body 1 and a cylinder rod 2, and is characterized in that: a sealing end cap 3 fixed to the cylinder body 1 is sleeved at the connection between the cylinder body 1 and the cylinder rod 2, and a cleaning element 5 for connecting to the sealing end cap 3 is sleeved on the surface of the cylinder rod 2, and a cleaning element 4 is provided on one side of the cleaning element 5, and a trigger member 6 is fixed on the side of the cylinder rod 2 away from the cleaning element 4. The cylinder rod 2 moves and retracts so that the trigger member 6 contacts the cleaning element 5 for cleaning. In actual implementation, in actual application, the cylinder rod 2 will slide back and forth along the length direction of the cylinder body 1. During the reciprocating sliding of the cylinder rod 2, the trigger member 6 will contact the cleaning element 4 and exert a certain force on the cleaning element 4. The cleaning element 4 subjected to the force will clean the surface of the cylinder rod 2, reducing the occurrence of dust following the cylinder rod 2 into the interior of the cylinder body 1, thereby ensuring the overall wear resistance and sealing effect of the hydraulic cylinder.

[0038] Optionally, the cleaning element 5 includes a corrugated airbag 51 sleeved on the surface of the cylinder rod 2 and connecting pieces 52 connected to both ends of the corrugated airbag 51;

[0039] One of the connecting pieces 52 is fixed to the corresponding sealing end cap 3, and a nozzle 53 is fixed to the surface of the other connecting piece 52. In actual implementation, when the corrugated airbag 51 in the cleaning element 5 is subjected to pressure, it will be compressed. The gas pressure inside the compressed corrugated airbag 51 will increase, and the increased pressure inside the corrugated airbag 51 will be ejected through the nozzle 53 to clean the dust on the surface of the cylinder rod 2.

[0040] Optionally, a nozzle 54 is fixed to the end of the nozzle 53, wherein the bellows airbag 51 has a pressurizing chamber 55 therein, compressing the bellows airbag 51 to increase the pressure and cause the gas to be ejected through the nozzle 53. In actual implementation, the design of the nozzle 53 allows the pressurized gas to be directed and ejected in multiple dimensions, thereby achieving a more comprehensive cleaning of the cylinder rod 2 and a better cleaning effect.

[0041] Optionally, the cleaning element 5 further includes a corner rod 56 connected to the outside of another connecting piece 52, and the ends of the multiple corner rods 56 are commonly fixed with a lower trigger plate 57 sleeved on the surface of the cylinder rod 2. In actual implementation, when the cylinder rod 2 slides toward the cylinder body 1, the trigger member 6 on the cylinder rod 2 will contact the connecting piece 52. The connecting piece 52 under pressure will act on the corner rod 56 and compress the corrugated airbag 51. The compressed corrugated airbag 51 will increase the pressure to clean the cylinder rod 2.

[0042] Optionally, the trigger member 6 includes an upper trigger plate 61 fixed to the surface of the cylinder rod 2;

[0043] A trigger rod 62 is provided on one side of the upper trigger plate 61 corresponding to the lower trigger plate 57. In actual implementation, when the trigger member 6 moves along with the cylinder rod 2, the trigger rod 62 will preferentially come into contact with the corresponding connecting piece 52, and the trigger plate 57 will not come into contact with the connecting piece 52 and the cleaning element 4.

[0044] Optionally, the cleaning element 4 includes a collar 41 fixed to the inner sides of the plurality of corner rods 56, with a cleaning sheet 42 fixed to the inner side of the collar 41. In actual implementation, a through slot 43 is defined on the inner side of the cleaning sheet 42, which allows the inner side of the cleaning sheet 42 to be in close contact with the surface of the cylinder rod 2. In actual implementation, when the cylinder rod 2 moves toward the cylinder body 1, the cleaning sheet 42 is stationary, so the cleaning sheet 42 slides relative to the cylinder rod 2, thereby cleaning dust from the surface of the cylinder rod 2.

[0045] Optionally, the surface of the cleaning sheet 42 is further provided with exhaust mesh holes 44, and the plurality of nozzles 54 are all distributed and extended in the direction of the exhaust mesh holes 44. In actual implementation, after the corrugated airbag 51 is pressurized and ejected through the nozzles 54, the ejected pressure can not only directly act on the surface of the cylinder rod 2 to clean dust on the surface, but also part of the gas can act on the exhaust mesh holes 44 and pass through the exhaust mesh holes 44 to clean dust attached thereto, thereby further improving the cleaning effect of the device and effectively preventing dust from falling into the cylinder body 1 and affecting the wear resistance and sealing effects.
