[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 The present invention provides a hydraulic cylinder barrel inner wall cleaning device, comprising: cylinder barrel 1.

[0020] Among them, such as Figure 1 and Figure 2As shown, a bracket 10 is fitted to the outer wall of the cylinder 1, and a base 9 is fixedly connected to the bottom of the bracket 10. The bracket 10 supports the cylinder 1 for horizontal placement. One end of the cylinder 1 is provided with an end cap 2, and one end of the end cap 2 is provided with a flange 4. Two annular clamps 11 are symmetrically provided on the outer wall of the cylinder 1. The annular clamps 11 can pass around the outer wall of the cylinder 1 and be fixed on the bracket 10, thereby stabilizing the cylinder 1 on the bracket 10.

[0021] In this embodiment, as Figures 1-4 As shown, two fixing plates 5 are symmetrically fixed to the inner wall of the flange 4. An annular frame 13 is fixedly connected to the end of the fixing plate 5. Several nozzles 8 are evenly distributed on the annular frame 13. A water supply channel 15 is provided inside the annular frame 13. A pipe joint 14 is embedded in the center of one side of the annular frame 13. One end of the pipe joint 14 is connected to the water supply channel 15. An external hydraulic cylinder or air cylinder can be bolted to one side of the flange 4, so as to facilitate the pulling and moving of the flange 4, the fixing plate 5 and the annular frame 13.

[0022] In use, two fixing plates 5 are symmetrically fixed to the inner wall of the flange 4 at the end of the end cap 2. The end of the fixing plate 5 is fixedly connected to the ring frame 13. When the end cap 2 is opened as a whole, the inner wall of the cylinder 1 is left outside. The flange 4 is driven by an external hydraulic cylinder or air cylinder to move the ring frame 13. When the ring frame 13 moves, it can scrape and clean the attachments on the inner wall of the cylinder 1, making it convenient to clean the inner wall of the cylinder 1 when it is not in use. In addition, several nozzles 8 are evenly distributed on the ring frame 13, and the ring frame 13 is provided with a water supply channel 15. The water supply channel 15 is connected to the nozzles 8. When connected to the external water supply system through the pipe joint 14 and the water inlet pipe 7, the cleaning liquid can be delivered to the nozzles 8 through the water supply channel 15 and sprayed onto the inner wall of the cylinder 1.

[0023] Furthermore, the pipe fitting 14 is threadedly connected to the water inlet pipe 7 via the external thread 12. The water inlet pipe 7 and the pipe fitting 14 can be connected and disconnected by turning the external thread 12, which facilitates the replacement of the water inlet pipe 7.

[0024] like Figure 1 and Figure 3 As shown, a cylinder 3 is fixedly connected to one side of the flange 4, and the outer diameter of the cylinder 3 is smaller than the inner diameter of the opening of the end cover 2. When the end cover 2 is completely separated from the cylinder 1, the flange 4 can allow the fixing plate 5 and the water inlet pipe 7 to pass through the opening of the end cover 2. The cylinder 3 can cover and protect one end of the fixing plate 5 and the water inlet pipe 7, so as to prevent the fixing plate 5 and the water inlet pipe 7 from colliding with the inner wall of the end cover 2 and causing damage when they pass through the opening of the end cover 2.

[0025] Based on the above technical solution, the working steps of this solution are summarized as follows: In this utility model, two fixing plates 5 are symmetrically fixed to the inner wall of the flange 4 at the end of the end cover 2. The end of the fixing plate 5 is fixedly connected to the ring frame 13. When the flange 4 is moved, the ring frame 13 can be moved. When the ring frame 13 moves, it can scrape and clean the deposits on the inner wall of the cylinder 1, which is convenient for cleaning the inner wall of the cylinder 1 when it is not in use.

[0026] In addition, several nozzles 8 are evenly distributed on the ring frame 13, and a water supply channel 15 is provided inside the ring frame 13. The water supply channel 15 is connected to the nozzles 8. When connected to an external water supply system through the pipe joint 14, the cleaning fluid can be transported to the nozzles 8 through the water supply channel 15 and sprayed onto the inner wall of the cylinder 1. The spraying operation assists in scraping and cleaning, further improving the cleanliness and cleaning efficiency of the hydraulic cylinder.

[0027] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
