Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, in particular to a hydraulic cylinder with a dust cleaning function. 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 it is used to achieve reciprocating motion, the reduction device can be eliminated, there is no transmission gap, and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. Publication No. CN206802002U discloses a hydraulic cylinder, the key points of its technical solution are that it includes a tubular cylinder barrel, a cylinder bottom fixed to the cylinder barrel, a piston rod, a piston fixed to one end of the piston rod and sliding in the cylinder barrel, a spare cap fixed to the end of the cylinder barrel away from the cylinder bottom, and a sealing structure. The piston divides the interior of the cylinder barrel into a rod chamber and a rodless chamber. The cylinder barrel is opened with two holes that connect the rod chamber and the rodless chamber respectively. The front oil port and the rear oil port of the rod chamber, the piston rod passes through the spare cap and extends out of the cylinder, and a buffer groove is opened on the inner wall of the cylinder near the spare cap. When the piston moves to the buffer groove, the buffer groove can connect the rod chamber and the rodless chamber, and a better buffering effect can be achieved without increasing the size of the hydraulic cylinder. Although the product has a good buffering effect as a whole, it is not convenient to clean the internal debris and impurities, and tools are needed for overall disassembly and cleaning, which increases the difficulty of overall maintenance and reduces the cleaning efficiency. The practicality is poor and needs to be improved. Utility Model Content

A pull head 10 is fixedly installed at one end of the limiting rod 9 to facilitate pulling the limiting rod 9. A tension spring 11 is fixedly installed on the side of the pull head 10 to allow the limiting rod 9 to automatically restore. The brush ring 6 is slidably connected to the inner wall of the outer cylinder 1 to automatically clean the interior of the outer cylinder 1. The brush ring 6 is a double-layer structure to achieve a better cleaning effect. The limiting rod 9 is slidably connected to the limiting block 7 to automatically lock and fix the top cover 3. One end of the tension spring 11 is fixedly connected to the fixed block 8 to allow the limiting rod 9 to automatically restore. The pull head 10 is T-shaped, which is convenient for grabbing the pull head 10 for pulling. The tension spring 11 is sleeved on the surface of the limiting rod 9 to allow the limiting rod 9 to slide smoothly.

[0024] Embodiment 2

[0025] See also Figure 3 , 5 The inside of the mounting ring B4 and the mounting ring A2 are both threadedly connected with a screw rod 12, so that the pressure block 14 can move automatically. One end of the screw rod 12 is rotatably connected with the pressure block 14, so that the mounting ring A2 and the mounting ring B4 can be pressed and fixed to the equipment. A guide rod 15 is fixedly installed on the side of the pressure block 14, so that when the pressure block 14 moves, it will not rotate with the rotation of the screw rod 12. The guide rod 15 is slidably connected between the mounting ring A2 and the mounting ring B4, so that the pressure block 14 moves more smoothly and stably. The shape of the pressure block 14 is trapezoidal, which makes the connection between the hydraulic cylinder and the equipment more stable and reduces wear.

[0026] Working principle: First, when it is necessary to clean the interior, you can grab the pull head 10 and pull it, so that the pull head 10 drives the limit rod 9 to move, so that the limit rod 9 slides inside the fixed block 8 and the limit block 7. When the limit rod 9 slides out from the inside of the limit block 7, you can grab the top cover 3 and pull it, so that the top cover 3 slides on the upper surface of the outer cylinder 1. When the top cover 3 slides upward, it can drive the mounting rod 5 to pull the brush ring 6, so that the brush ring 6 and the internal debris and impurities are cleaned. When cleaning is completed, the brush ring 6 can be aligned with the outer cylinder 1, and the brush ring 6 and the mounting rod 5 can be inserted into the interior of the outer cylinder 1. Then, the limit block 7 on the top cover 3 is aligned with the fixed block 8 and pressed, so that the limit block 7 slides to the position of the fixed block 8. When the limit block 7 slides to the inside of the fixed block 8, the tension spring 11 drives the pull head 10 and the limit rod 9 to move, so that the limit rod 9 slides to the inside of the limit block 7 to clamp and fix the top cover 3.
