During the adjustment process of the hydraulic cylinder 31, the friction with the ball 209 causes the ball 209 to rotate, which effectively reduces the total friction of the hydraulic cylinder 31 when the angle is tilted.

[0035] Specifically, the electric push rod 202 is started to drive the fixed rod 203 to descend. During the descent process, the fixed rod 203 enters the slot 204 and applies pressure to the pressure plate 205, causing the pressure plate 205 to press down, thereby causing the connecting rod 206 to rotate around the rotating shaft 207. The groove block 208 fixed at the other end of the connecting rod 206 rises accordingly, providing support for the hydraulic cylinder 31, thereby achieving adjustment of the angle of the hydraulic cylinder 31. During the adjustment process of the hydraulic cylinder 31, the friction with the ball 209 causes the ball 209 to rotate, effectively reducing the total friction force of the hydraulic cylinder 31 when the angle is tilted. By controlling the descending distance of the fixed rod 203, the tilt angle of the hydraulic cylinder 31 can be accurately adjusted to adapt to the cleaning operations of the electrified railway contact network insulators in various scenarios.

[0036] Reference Figure 1 and Figure 3 The front and rear sides of the extension plate 30 are fixedly connected with a plurality of fixing rings 29 , the rubber tube 17 is installed on the inner side of the fixing ring 29 , the front and rear sides of the bottom plate 1 are fixedly connected with a protective frame 6 , and the inner side of the protective frame 6 is fixedly connected with a reinforcing rib 5 .

[0037] Specifically, the position of the rubber tube 17 can be fixed by the fixing ring 29, and the cooperation between the protection frame 6 and the reinforcing rib 5 can protect the staff and prevent them from falling.

[0038] Working principle: The connecting rail 8 and the bottom plate 1 are installed on the rail vehicle by means of bolts 7, the universal cover 14 is opened to inject water and a well-proportioned detergent into the mixing barrel 12, the driving motor 16 is turned on to drive the mixing blade 15 to rotate, and the water and the detergent are evenly mixed, the water pump 10 is turned on simultaneously to extract the water from the mixing barrel 12 through the water inlet pipe 11, and at the same time, it is discharged into the square ring pipe 34 through the drain pipe 9, and the valves 35 at different positions are controlled to be opened and closed to achieve the effect of controlling the different water spraying effects of the two high-pressure nozzles 19, and at the same time, the hydraulic cylinder 31 is turned on to drive the extension plate 30 to extend, and the extension plate 30 is extended to the top position of the electrified railway contact network insulator that needs to be cleaned, and the high-pressure nozzle 19 is turned on to allow the water source to spray out to clean the electrified railway contact network insulator, and at the same time The small motor 23 is turned on to drive the driving pulley 24 to rotate. The rotation of the driving pulley 24 is linked to the driven pulley 27 by the connecting belt 25 to rotate synchronously. The rotation of the driven pulley 27 and the driving pulley 24 drives the winding wheel 28 to rotate synchronously, thereby winding the wire rope 21. The winding of the wire rope 21 drives the limit ring 20 to rise, and then the nozzle angle of the high-pressure nozzle 19 is tilted and adjusted. When the high-pressure nozzle 19 is tilted, the spring 18 is stretched. The back and side surfaces of the electrified railway contact network insulator can be cleaned by tilting the angle of the high-pressure nozzle 19. At the same time, the high-pressure nozzle 23 is turned on to transport and spray water through the straight pipe 4 to clean the front of the electrified railway contact network insulator. The multi-faceted cleaning work can be automatically performed;

[0039] And the electric push rod 202 is turned on to drive the fixed rod 203 to descend. The fixed rod 203 descends and slides into the slot 204 to press down the pressure plate 205. The downward pressure of the pressure plate 205 causes the connecting rod 206 to rotate on the rotating shaft 207, so that the groove block 208 fixed at the other end of the connecting rod 206 is tilted, and the groove block 208 lifts the hydraulic cylinder 31 to adjust the angle of the hydraulic cylinder 31. When the hydraulic cylinder 31 is adjusted, friction is generated with the ball 209 to rotate the ball 209, thereby reducing the overall friction force when the hydraulic cylinder 31 is tilted. The tilt angle of the hydraulic cylinder 31 can be controlled by the descending distance of the fixed rod 203, so as to adapt to the cleaning work of the electrified railway contact network insulator in multiple scenarios.
