Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinder maintenance, and more specifically, to a hydraulic cylinder barrel high-efficiency cleaning device. Background Art

[0002] The 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 deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides. The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

[0003] However, traditional hydraulic cylinder cleaning equipment only has a brush structure of fixed size, which means that the existing cleaning equipment can only clean the hydraulic cylinder with a fixed brush size. When faced with hydraulic cylinders of different diameters, the cleaning effect is poor because it cannot adapt to the cleaning range by itself, making it difficult to clean the hydraulic cylinder efficiently.

[0004] In view of the above technical defects, a solution is now provided. Utility Model Content

[0022] like Figure 2 and Figure 3 As shown, the self-expanding brushing mechanism 4 includes a slide plate 41 slidably mounted on one side of the support plate 2, a motor 42 is fixedly mounted on one side of the slide plate 41, the motor 42 is vertically downwardly arranged, a rotating rod 43 is provided at the bottom of the motor 42, the rotating rod 43 is vertically downwardly arranged, the rotating rod 43 and the hydraulic cylinder 3 are arranged corresponding to each other, and the rotating rod 43 is driven by the motor 42 to rotate in the hydraulic cylinder 3.

[0023] like Figure 3 and Figure 4As shown, a positioning cylinder 44 is fixedly installed at the bottom of the rotating rod 43, and then the rotation of the rotating rod 43 drives the positioning cylinder 44 to rotate synchronously, and a plurality of sliding pads 45 are slidably installed on the outer wall of the positioning cylinder 44, that is, the positioning cylinder 44 drives the plurality of sliding pads 45 on the outer wall to rotate synchronously, and the plurality of sliding pads 45 are arranged in a ring-shaped and equidistant manner, and one side of the plurality of sliding pads 45 is hinged with a first top plate 46, and the plurality of first top plates 46 are arranged in an inclined state, and one side of the plurality of first top plates 46 is hinged with a push block 47, and the outer wall of the plurality of push blocks 47 is hinged with a second top plate 48. The first top plate 46 on one side of the sliding pad block 45 and the multiple second top plates 48 connected by multiple push blocks 47 rotate synchronously. The multiple second top plates 48 are hinged on the outer wall of the positioning cylinder 44. The multiple second top plates 48 and the first top plates 46 are arranged corresponding to each other. Then, under the centrifugal force of rotation, the push blocks 47 on one side of the first top plate 46 and the second top plate 48 are offset outward, and the outer walls of the first top plate 46 and the second top plate 48 are jointly fixed with a limit spring 49, so that the first top plate 46 and the second top plate 48 approach each other and squeeze the limit spring 49.

[0024] like Figure 3 and Figure 4 As shown, a top weight plate 410 is hinged on one side of the multiple push blocks 47. When the top weight plates 410 on one side of the multiple push blocks 47 are rotated, the weight of the top weight plates 410 is centrifugally moved, and the top weight plates 410 are arranged in a vertical state.

At this time, the rotation of the rotating rod 43 drives the positioning cylinder 44 to rotate synchronously, and then the positioning cylinder 44 drives the multiple sliding pads 45 on the outer wall to rotate synchronously. The first top plate 46 on one side of the multiple sliding pads 45 and the multiple sliding pads 45 connected by the multiple push blocks 47 are The second top plate 48 rotates synchronously. At this time, centrifugal force is generated when the top weight plate 410 on one side of the multiple push blocks 47 rotates synchronously, that is, the first top plate 46 and the second top plate 48 are pulled outward by the push block 47 and approach each other and squeeze the limit spring 49, so that the top weight plate 410 is deflected outward and drives the brush plate 411 to fit the inner wall of the hydraulic cylinder 3, and in the process of self-rotation and reciprocating downward movement, the inner wall of the hydraulic cylinder 3 is rotated, scraped and cleaned.
