[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, such as Figure 1 - Figure 3 As shown, this utility model provides a tunnel dust suppression and spraying maintenance tool, including a movable support 1, a telescopic frame 2 at the upper end of the movable support 1, universal rollers 3 connected to the four corners of the bottom of the movable support 1, a spraying assembly 4 connected to the top surface of the telescopic frame 2, the spraying assembly 4 including a support frame 401, a bidirectional screw 405 inserted inside the support frame 401, a bearing 406 connected to the rear end of the bidirectional screw 405, a throttle 407 connected to the front end of the bidirectional screw 405, two sets of crossbars 410 symmetrically connected to the surface of the bidirectional screw 405, and fixed water pipes 403 connected to the upper and lower ends of the crossbars 410. Atomizing nozzles 404 are equidistantly connected to the surface of the support frame 401. A set of flexible hoses 408 are connected to one end of the two sets of fixed water pipes 403. A valve switch 409 is connected to one end of the flexible hose 408. Slider 402 is connected to both sides of the two sets of crossbars 410. A fixed connection is formed between the bidirectional screw 405 and the throttle 407. A rotatable connection is formed between the bidirectional screw 405 and the bearing 406. The crossbar 410 is M-shaped. A threaded connection is formed between the bidirectional screw 405 and the two sets of crossbars 410. The inner walls on both sides of the support frame 401 that match the slider 402 are provided with grooves 411. A sliding connection is formed between the slider 402 and the grooves 411.

[0022] The overall effect of Embodiment 1 is that after connecting the hose 408 to the external water pipe, the valve switch 409 can be opened to ensure that water can enter the two sets of fixed water pipes 403 through the hose 408, and then the water is sprayed out through the atomizing nozzle 404, which can suppress dust inside the tunnel. At the same time, when it is necessary to adjust the position of the two sets of crossbars 410 according to the actual situation, the handle 407 can be turned to drive the bidirectional screw 405 to rotate, and the bearing 406 can improve the stability of the bidirectional screw 405 during rotation. When the bidirectional screw 405 rotates, it will also rotate simultaneously with the two sets of crossbars 410 through the threaded hole. This rotation will drive the two sets of crossbars 410 to move, thereby moving the position of the atomizing nozzle 404. The design of the slider 402 and the slide groove 411 can improve the stability of the two sets of crossbars 410 when adjusting their positions. This allows the two sets of crossbars 410 to be adjusted according to the actual situation. The simple moving bracket 1 allows the spraying system to be easily moved to different areas, improving the flexibility of spraying.
