[0002] Tunnel construction refers to the general term for the construction methods, construction techniques, and construction management of tunnels and underground chambers. During tunnel construction, due to the complexity of geological conditions and the particularity of construction methods, a large amount of dust is often generated, seriously affecting the construction environment, the health of construction workers, and the construction progress.

The top end of the rotating column 4 is fixedly connected with an adjusting ring 7. The top end of the rotating column 4 is fixedly connected with a central column 8. The top end of the dust removal box 2 is fixedly connected with a water guiding component 9. The outer side of the central column 8 is rotatably connected with an atomization box 10. The outer side of the atomization box 10 is fixedly connected with a boosting atomizing nozzle 11. The outer side of the atomization box 10 is fixedly connected with a connecting hose 12 whose other end communicates with the outer side of the central column 8. The inner side of the adjusting ring 7 is fixedly connected with an up-and-down adjusting component 13. The outer side of the central column 8 is fixedly connected with a connecting spring 24 whose other end is fixedly connected with the outer side of the atomization box 10. The inner side of the dust removal box 2 is provided with a dust removal liquid 17.

[0035] Among them, the bottom end of the fixed bottom plate 1 is fixedly connected with four moving wheels 14. The top end of the fixed bottom plate 1 is fixedly connected with a moving handle 15. The inner side of the dust removal box 2 is fixedly connected with an observation glass 16.

[0036] The moving wheels 14 cooperate with the moving handle 15 to enable the fixed bottom plate 1 to move in position, so that the fixed bottom plate 1 can move in position in the tunnel. At the same time, the observation glass 16 can show the remaining amount of the dust removal liquid 17.

[0037] Among them, the power transmission component 6 includes a first gear 61 fixedly connected to the outer side of the output shaft at the top of the double-shaft linear motor 5. A second gear 62 is fixedly connected to the outer side of the rotating column 4, and the outer sides of the first gear 61 and the second gear 62 are meshed with each other.

[0038] Starting the double-shaft linear motor 5 can cause the first gear 61 to rotate, thereby driving the second gear 62 to rotate, and then the rotating column 4 will rotate.

[0039] Among them, the water guiding component 9 includes a water guiding pump 91 fixedly connected to the top of the dust removal box 2. A water inlet pipe 92 extending to the inside of the dust removal box 2 is fixedly connected to the outer side of the water inlet end of the water guiding pump 91, and a water outlet pipe 93 whose other end is rotatably connected to the bottom end of the rotating column 4 is fixedly connected to the outer side of the water outlet end of the water guiding pump 91.

[0040] Starting the water guiding pump 91 can introduce the dust removal liquid 17 into the central column 8 through the water outlet pipe 93 through the water inlet pipe 92.

[0042] The multiple number of the pressurized atomizing nozzles 11 can increase the atomizing area, thereby improving the overall atomizing effect of the device.

[0043] Working principle:

[0044] After moving the fixed bottom plate 1 to the construction tunnel to be dust-removed through the cooperation of the moving wheels 14 and the moving handle 15, starting the water guiding pump 91 can introduce the dust removal liquid 17 into the central column 8 through the water outlet pipe 93 through the water inlet pipe 92, and at the same time introduce it into the atomizing box 10 through the connecting hose 12. The dust removal liquid 17 is atomized and sprayed out through the pressurized atomizing nozzles 11 on the outer side of the atomizing box 10, and the inner side of the construction tunnel can be dusted;

[0045] At the same time, starting the double-shaft linear motor 5 can cause the first gear 61 to rotate, thereby driving the second gear 62 to rotate, and then the rotating column 4 will rotate, which can cause the atomizing box 10 to rotate and make the overall atomizing effect of the device better.

[0046] Example two, by Figures 4-6Given that the up-and-down adjustment component 13 includes an adjustment hydraulic rod 131 fixedly connected to the inner side of the adjustment ring 7. The top end of the telescopic end of the adjustment hydraulic rod 131 is fixedly connected with a T-shaped connecting rod 132. An adjustment spring 133 is fixedly connected to the inner side of the adjustment ring 7, and the other end of the adjustment spring 133 is fixedly connected to the outer side of the T-shaped connecting rod 132.

[0047] Starting the adjustment hydraulic rod 131 can cause the T-shaped connecting rod 132 to move up and down, and then through the connecting spring 24, the atomization box 10 can move up and down.

[0048] The adjustment hydraulic rod 131 is driven by a battery.

[0049] Wherein, the top end of the T-shaped connecting rod 132 is arranged in an arc shape. The top end of the T-shaped connecting rod 132 is in contact with the bottom end of the atomization box 10. The number of atomization boxes 10 is multiple, and the multiple atomization boxes 10 are distributed in a circular array outside the central column 8.

[0050] The top end of the T-shaped connecting rod 132 being arranged in an arc shape can facilitate the rotation of the atomization box 10 and improve the rotation effect of the atomization box 10.

[0051] Wherein, a cold air blower 19 is fixedly connected to the top end of the fixed bottom plate 1. The outer side of the air outlet end of the cold air blower 19 is fixedly connected with a cold air duct 20 extending into the dust removal box 2. A plurality of cold air holes 21 are formed on the outer side of the cold air duct 20, and the plurality of cold air holes 21 are evenly distributed on the outer side of the cold air duct 20.

[0052] The cold air generated by the cold air blower 19 is introduced into the cold air holes 21 through the cold air duct 20. Thus, the dust removal liquid 17 can be cooled. At the same time, in summer, the construction tunnel can be cooled to a certain extent, improving the tunnel construction effect.

[0053] A plurality of through holes are formed on the outer side of the dust removal box 2, and the through holes can facilitate the discharge of the excess air inside the dust removal box 2.

[0054] Wherein, a stirring rod 22 is fixedly connected to the outer side of the output shaft at the lower end of the double-shaft linear motor 5 through a coupling. Stirring blades 23 are fixedly connected to the outer side of the stirring rod 22.

[0055] Starting the double-shaft linear motor 5 can cause the stirring rod 22 to rotate. Then, the stirring blades 23 can stir the dust removal liquid 17, which can improve the cooling effect of the dust removal liquid 17.

[0056] Working principle:

[0057] During the process of moving and dust-removing by the dust-removing box 2, the adjusting hydraulic rod 131 can be activated to move the T-shaped connecting rod 132 up and down. Under the action of the connecting spring 24, the atomizing box 10 can be rotated, thereby improving the overall atomizing effect of the device. The cold air generated by the cold air blower 19 enters the dust-removing liquid 17 through the cold air pipe 20. During the startup process of the double-shaft linear motor 5, the stirring rod 22 will rotate, and then the stirring blades 23 can stir the dust-removing liquid 17, improving the cooling effect of the dust-removing liquid 17.
