Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, specifically to a high-strength, wear-resistant hydraulic cylinder body. Background Technology

[0002] Hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy and perform linear reciprocating motion. They are widely used in the hydraulic systems of various machines.

[0003] In the prior art, such as the Chinese patent announcement number CN218913336U "A Wear-resistant Hydraulic Cylinder Body", when the telescopic column of this utility model moves the hydraulic oil in the hydraulic cylinder by telescopic movement, when the particulate matter contained in the hydraulic oil moves to the position of the collection trough, the particulate matter can be temporarily stored in the collection trough under the attraction of the magnet. This can prevent the particulate matter from causing wear and damage to the telescopic column during its movement along the hydraulic cylinder, thus extending the service life of the device. In addition, the reinforcing sleeve is fixed in position by being embedded in the groove opened on the outer surface of the hydraulic cylinder by the limiting strip, which has strong stability. This not only increases the stability of the hydraulic cylinder, but also prevents the hydraulic cylinder from leaking due to the thinning of the cylinder wall caused by the opening of the collection trough.

[0004] While the aforementioned existing technologies can treat metallic impurities, hydraulic oil may also contain other non-metallic impurities during use, such as dust and sand particles from the air that enter the oil through the oil tank and oil pipes. These non-metallic impurities may cause wear on the inner wall of the cylinder. In addition, the lack of auxiliary support on the outer side of the cylinder will reduce its strength.

The sealing plug 8 can clean the impurities filtered out by the filter screen 9, reducing the wear of impurities on the inner wall of the cylinder body 1.

[0019] As a technical optimization of this utility model, both oil supply components 4 are threadedly fixed to the cylinder body 1, and the oil supply pipe 7 corresponds to the oil inlet position on the outside of the cylinder body 1.

[0020] In this embodiment: by setting up the oil supply pipe 7, the oil supply component 4 can be connected and fixedly installed with the oil inlet of the cylinder 1 through the oil supply pipe 7, which facilitates the delivery of hydraulic oil.

[0021] As a technical optimization of this utility model, the inner side of the oil conveying component 4 is provided with a first control groove 10, the first movable plate 11 is rotatably installed with the first control groove 10, and the first movable plate 11 and the first control groove 10 are matched and sealed together; the inner side of the first control groove 10 is fixedly installed with a first limiting strip 12, and the bottom of the first limiting strip 12 is correspondingly abutted against the top of the first movable plate 11.

[0022] In this embodiment: by setting a first movable plate 11 and a first limiting strip 12, it is convenient to deliver hydraulic oil unidirectionally to the oil supply pipe 7 position through the connecting pipe 5 and the first control groove 10 for injection into the cylinder 1. The first limiting strip 12 can restrict the movement of the first movable plate 11, so that the first movable plate 11 can open the opening of the first control groove 10 to carry out the hydraulic oil delivery operation.

[0023] As a technical optimization of this utility model, a second control groove 13 is provided on the inner side of the oil conveying component 4, and the second movable plate 14 is rotatably installed with the second control groove 13, and the second movable plate 14 and the second control groove 13 are matched and sealed together; a second limiting strip 15 is fixedly installed on the inner side of the second control groove 13, and the bottom of the second limiting strip 15 abuts against the top of the second movable plate 14.

[0024] In this embodiment: by setting the second movable plate 14 and the second limiting strip 15, it is convenient to transport hydraulic oil unidirectionally to the position of the connecting pipe 5 through the oil supply pipe 7 and the second control groove 13 so that the hydraulic oil in the cylinder 1 can flow back. The second limiting strip 15 can restrict the movement of the second movable plate 14, so that the second movable plate 14 can open the opening of the second control groove 13 to carry out the hydraulic oil return transport operation.

[0025] As a technical optimization of this utility model, the first movable plate 11 is located below the oil pipeline 7, and the second movable plate 14 is located above the oil pipeline 7.

[0026] In this embodiment: by setting the first movable plate 11, when hydraulic oil is transported to the position of the oil supply pipe 7 through the connecting pipe 5, the hydraulic oil is unidirectionally transported to the position of the oil supply pipe 7 by opening the first control groove 10 through the first movable plate 11. By setting the second movable plate 14, when hydraulic oil is transported to the position of the connecting pipe 5 through the oil supply pipe 7, the hydraulic oil is unidirectionally transported to the position of the connecting pipe 5 by opening the second control groove 13 through the second movable plate 14.

[0027] Working Principle: When using this hydraulic cylinder, the connecting pipe 5 is connected to the external oil pipe. The sealing plug 8 cleans the impurities filtered out by the filter screen 9, reducing wear on the inner wall of the cylinder body 1. Hydraulic oil is unidirectionally transported through the connecting pipe 5 and the first control groove 10 to the oil delivery pipe 7 and injected into the cylinder body 1. The first limit bar 12 restricts the movement of the first movable plate 11, causing the hydraulic oil to lift the first movable plate 11 and open the opening of the first control groove 10 for hydraulic oil delivery. The hydraulic oil, after being filtered through the filter screen 9 via the connecting pipe 5, is then delivered to the cylinder body 1 through the oil delivery pipe 7. The hydraulic oil is transported unidirectionally through the oil supply pipe 7 and the second control groove 13 to the position of the connecting pipe 5 to return the hydraulic oil in the cylinder 1. The movement of the second movable plate 14 can be restricted by the second limit bar 15, so that the hydraulic oil pushes the second movable plate 14 to open the opening of the second control groove 13 for the return transport of hydraulic oil. Finally, the impurities filtered out by the filter screen 9 can be cleaned out by rotating the sealing plug 8. During use, the hydraulic oil in the two oil supply components 4 installed on the outside of the cylinder 1 is transported in opposite directions, which makes it easier to push the piston 6 and make the piston rod 2 extend and retract.
