[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As shown in the figure, a mobile spray dust removal device for tunnel construction includes a body 1, an upper cover 4 is installed on the upper part of the body 1, and a turntable 12 is rotatably installed on the surface of the upper cover 4, wherein the turntable 12 is installed on the surface of the upper cover 4 through a bearing, and a wind tube 7 is provided above the turntable 12, which rotates synchronously with the turntable 12. When the turntable 12 rotates, the wind tube 7 can be driven to rotate to achieve the effect of angle deflection, and a mounting plate 3 that rotates synchronously with the turntable 12 is connected below the turntable 12, and the mounting plate 3 extends in the circumferential direction and radial direction. The limit block 26 is extended, and travel switches 23 are installed on both sides of the limit block 26. The surface of the upper cover 4 is provided with a plurality of jacks 5 evenly distributed around the center of the turntable 12, and the limit rods 13 are installed in at least two of the jacks 5. When the limit block 26 rotates, the travel switches 23 on both sides can contact the limit rods 13 respectively. In this way, the structural design of the travel switch 23, the limit block 26 and the limit rod 13 can be used to limit the rotation angle of the turntable 12, thereby satisfying the angle swing in different environmental boxes.

[0020] A motor bracket 17 is installed inside the body 1, and a driving motor 16 is installed on the motor bracket 17. The output shaft of the driving motor 16 is upward and connected to the main shaft 14. The mounting disk 3 and the turntable 12 are respectively connected to the main shaft 14. The driving motor 16 is used as a power source to drive the main shaft 14 and the mounting disk 3 and the turntable 12 on the main shaft 14 to rotate synchronously.

[0021] A support frame 6 is installed on the upper surface of the turntable 12 , and the middle part of the air cylinder 7 is hinged to the upper end of the support frame 6 , so that the air cylinder 7 has the freedom to swing at an angle relative to the support frame 6 .

[0022] A hydraulic cylinder 11 is hinged on the upper surface of the turntable 12, and the end of the telescopic rod of the hydraulic cylinder 11 is hinged on the connecting frame 9 at the lower end of the wind tube 7. A hydraulic component 15 is provided inside the body 1, wherein the hydraulic component 15 mainly includes a hydraulic oil tank, a hydraulic pump, an electric control valve, etc., which are used to control the telescopic operation of the telescopic rod on the hydraulic cylinder 11.

[0023] One end of the wind tube 7 is equipped with multiple nozzles 8 evenly distributed around the center of the wind tube 7, the nozzles 8 are connected to the water pump 20 through the water pipe 10, the other end of the water pump 20 is connected to the pipeline, and the end of the pipeline is placed in the water tank 19 on one side of the body 1, and the other end of the wind tube 7 is equipped with a fan 21. After the water pump 20 is started, water can be sprayed out from the nozzles 8 and sprayed forward under the action of the fan 21 to form a spray effect.

[0024] Fixed sleeves 25 are respectively installed on both sides of the limit block 26, and a telescopic sleeve 24 is slidably connected inside the fixed sleeve 25. One end of the telescopic sleeve 24 extends to the external position of the fixed sleeve 25, and the travel switch 23 is installed at the outer end of the telescopic sleeve 24. A spring 22 is installed in the internal cavity formed by the telescopic sleeve 24 and the fixed sleeve 25. This arrangement is mainly to avoid the hard collision problem caused by the travel switch 23 when it contacts the limit rod 13, so as to play a safety protection effect.

[0025] An electric control box 2 is also installed inside the body 1. The electric control box 2 is equipped with electrical components such as a PLC controller, a transformer, a frequency converter, and a battery. It is mainly used to realize automatic control of the drive motor 16, the water pump 20, the hydraulic pump, etc., thereby saving labor.

[0026] A plurality of moving wheels 18 are installed at the bottom of the body 1. In this example, the moving wheels 18 are arranged at the four corners of the body 1 and adopt a universal wheel structure, which can facilitate the movement of the body 1.

[0027] This mobile spray dust removal device for tunnel construction uses a water pump 20 to spray water in a water tank 19 through a water pipe 10 from a nozzle 8 to form a spray, and then, under the action of a fan 21, sprays the misty water vapor to the construction site to remove the dust generated during the construction. During use, the hydraulic cylinder 11 can be controlled to extend and retract through a PLC controller to adjust the angle between the wind tube 7 and the horizontal ground. At the same time, the turntable 12 and the support frame 6 can also be driven to rotate through a driving motor 16 to adjust the rotation angle of the wind tube 7 in the horizontal direction, which can reduce the frequency of moving the sprayer and reduce the staff's workload; when the construction area is small, the two limit rods 13 are inserted into different positions of the sockets 5 on the surface of the upper cover 4. In the process of the driving motor 16 driving the main shaft 14 to rotate, the limit block 26 on the mounting plate 3 will contact the limit rod 13. After the contact, the travel switch 23 on one side of the limit block 26 transmits an electrical signal to the PLC controller, and the PLC controller drives the main shaft 14 to reverse. When the travel switch 23 on the other side of the limit block 26 contacts the limit rod 13, the PLC controller drives the main shaft 14 to rotate forward, so that the purpose of reciprocating swing of the wind tube 7 can be achieved, which is conducive to expanding the dust removal area.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
