[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a subway tunnel cleaning device, comprising a rail flatbed trolley 1, the bottom surface of which is provided with four groups of symmetrically arranged rail wheels 11. The rail flatbed trolley 1 is the basic structure of the device, and the bottom surface is equipped with four groups of symmetrically arranged rail wheels 11 to ensure that the device can move smoothly on the subway track. Two groups of symmetrically arranged support frames 12 are fixedly connected to the surface of the rail flatbed trolley 1. The two groups of symmetrically arranged support frames 12 are fixed to the surface of the rail flatbed trolley 1 to form a support structure for the cleaning component 2, ensuring the stability and reliability of the device during use. A connecting plate 13 is fixedly connected to the tail end of the rail flatbed trolley 1, and a through-hole 14 is provided on the surface of the connecting plate 13. The through-hole 14 on the surface of the connecting plate 13 is used for a hook to pass through, and the entire device is moved by a rail engineering vehicle. The side wall of the support frame 12 is provided with a cleaning component 2, and the cleaning component 2 includes a cross 21. The cross 21 is fixedly connected to the side wall of the support frame 12. The cross 21 provides support and a stable foundation for the cleaning component 2, ensuring that other components can be reliably fixed thereon.

[0032] Reference Figure 2 - Figure 3The side wall of the cross 21 is provided with four groups of symmetrically arranged slide grooves 22, and the inner sliding connection of the slide groove 22 is provided with a moving seat 23. The slide groove 22 provides a stable moving track for the moving seat 23. The end of the moving seat 23 is fixedly connected with a sleeve 24. The four groups of sleeves 24 are slidably connected by a bend 25. A nozzle 26 is provided on the outer wall of the sleeve 24 and the bend 25. The moving seat 23 is responsible for carrying the sleeve 24 and is connected through the bend 25 so that the four groups of sleeves 24 and the bend 25 are connected to each other. The nozzle 26 is responsible for spraying water from the sleeve 24 and the bend 25 to flush the inner wall of the tunnel. Washing, the side wall of the movable seat 23 is provided with a through hole, and a guide rod 27 is slidably connected in the through hole. The end of the guide rod 27 is fixedly connected to the inner wall of the slide 22. The guide rod 27 is used to guide and position the movable seat 23 to ensure the stable movement of the movable seat 23. The end of the movable seat 23 is hinged with a traction plate 28, and the end of the traction plate 28 is hinged with a connecting seat 29. The side wall of the connecting seat 29 is provided with a through hole, and a screw rod 210 is threadedly connected in the through hole. One end of the screw rod 210 is fixedly connected to a hand wheel 211, and the other end of the screw rod 210 is rotatably connected to the side wall of the cross 21. The hand wheel 211 drives the screw rod 210 to rotate, thereby driving the movable seat 23 to move laterally along the direction of the screw rod 210. The movable seat 23 is driven to open by the traction plate 28, thereby adjusting the position between the four sets of sleeves 24, so that the nozzle 26 is close to the inner wall of the tunnel, improving the washing effect.

[0033] Reference Figure 1 A water storage barrel 3 is fixedly connected to the surface of the rail flatbed vehicle 1. A water inlet 31 is provided on the surface of the water storage barrel 3. The water storage barrel 3 is a storage device for cleaning water. The water inlet 31 facilitates adding water to the interior of the water storage barrel 3. A water pump 4 is fixedly connected to the surface of the water storage barrel 3. The water pump 4 is powered by a diesel generator installed on the surface of the rail flatbed vehicle 1. The input end of the water pump 4 passes through and is fixedly connected to the inner wall of the water storage barrel 3. The output end of the water pump 4 is fixedly connected to the side wall of the sleeve 24 via a telescopic hose 5. The water pump 4 is responsible for pumping water out of the water storage barrel 3 and delivering the cleaning water to the sleeve 24 and the nozzle 26 to achieve efficient flushing.

[0034] Working principle: The water pump 4 delivers water to the sleeve 24 through the telescopic hose 5, and then the water is sprayed out through the nozzle 26 to flush the inner wall of the subway tunnel. During the cleaning process, the movable seat 23 moves stably along the slide 22 with the assistance of the guide rod 27, ensuring that the nozzle 26 can evenly cover all parts of the inner wall of the tunnel. When the position of the nozzle 26 needs to be adjusted to adapt to tunnels of different sizes, the traction plate 28 and the connecting seat 29 are used in conjunction to enable the movable seat 23 to open or contract, thereby changing the distance between the sleeves 24 and realizing precise adjustment of the position of the nozzle 26. The combination of the handwheel 211 and the screw 210 provides power for the lateral movement of the movable seat 23, ensuring cleaning efficiency and effect.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
