Detailed implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Please refer to Figures 1-4 , the present invention provides a technical solution: a tunnel wall crack filling device, including: a base, a drilling structure, and a water spraying structure.

[0027] Refer to Figure 1 , the base includes a bottom plate 1, side plates 2 and a handle 3 respectively fixedly installed on the upper surface of the bottom plate 1, an adjusting plate 4 rotatably installed on the right side surface of the side plate 2, and an adjusting assembly arranged on the left side of the side plate 2.

The worm gear 12 is in meshing transmission with the worm 11, and the right end of the worm gear 12 is fixedly connected to the rotating shaft of the adjusting plate 4. Rotating the worm 11 can drive the worm gear 12 to rotate. By using the meshing transmission of the worm gear 12 and the worm 11, the adjusting plate 4 can be driven to rotate accordingly, and then the angle between the adjusting plate 4 and the bottom plate 1 can be changed. Moreover, the principle of self-locking of the worm gear 12 and the worm 11 can be used to prevent the adjusting plate 4 from rotating after being stressed.

[0029] Refer to Figures 1-2 , the drilling structure includes a sliding frame 5 slidably installed on the surface of the adjusting plate 4, a motor 6 fixedly installed on the inner wall of the sliding frame 5, and a drill bit 7 fixedly installed on the output end of the motor 6. The right side surface of the sliding frame 5 is fixedly installed with a handle 8. Driving the motor 6 can drive the drill bit 7 to rotate, and sliding the sliding frame 5 along the surface of the adjusting plate 4 can change the distance from the drill bit 7 to the bottom plate 1, and at the same time, the drill bit 7 can also be guided.

[0030] Place the bottom plate 1 at the position where the crack needs to be repaired. Then, use the adjustment component to change the angle between the adjustment plate 4 and the bottom plate 1, so as to drive the drill bit 7 to rotate synchronously and incline it to the crack surface. The operator holds the handle 8 and the grip 3 with both hands respectively. Then, drive the motor 6 to rotate and slide the handle 8 to drive the drill bit 7 to descend, so that the drill bit 7 can descend along the track of the adjustment plate 4, thereby guiding the movement track of the drill bit 7 and avoiding tilting during drilling. Furthermore, it can avoid the problems of the drill bit 7 breaking and the drilling position shifting due to the swinging and tilting of the drill bit 7.

[0031] Refer to Figure 2 and Figure 4 , the water spraying structure includes a guide ring 9 fixedly installed on the right side surface of the adjustment plate 4, a spray head 10 fixedly installed at the lower end of the guide ring 9, and a water supply component and an air injection component respectively arranged on the upper surface of the bottom plate 1. The inner wall of the guide ring 9 allows the drill bit 7 to pass through.

[0032] The water supply component includes a water storage tank 13 fixedly installed on the upper surface of the bottom plate 1, a connecting pipe 14 fixedly installed at the upper end of the water storage tank 13, a water guide pipe 15 fixedly installed at the water inlet end of the spray head 10, and a valve 16 fixedly installed on the surface of the grip 3. Water can be injected into the water storage tank 13, and a water injection port is arranged at the upper end of the water storage tank 13, and a sealing plug is arranged at the upper end of the water injection port.

[0033] One end of the connecting pipe 14 away from the water storage tank 13 is connected to the water inlet end of the valve 16, and one end of the water guide pipe 15 away from the spray head 10 is connected to the water outlet end of the valve 16. The other end of the connecting pipe 14 extends to the inner bottom wall of the water storage tank 13. The water in the water storage tank 13 can be introduced into the spray head 10 and sprayed out by using the water guide pipe 15 and the connecting pipe 14.

[0034] Refer to Figure 1 , the air injection component includes a pump 17 fixedly installed on the upper surface of the bottom plate 1, and an air guide pipe 18 fixedly installed at the exhaust end of the pump 17. One end of the air guide pipe 18 away from the pump 17 is connected to the inside of the water storage tank 13. The pump 17 can be used to inject air into the water storage tank 13, so as to generate high pressure in the water storage tank 13. When drilling, opening the valve 16 can make the water in the water storage tank 13 flow along the connecting pipe 14 and the water guide pipe 15 into the spray head 10 and spray out, so as to spray water on the drill bit 7 to cool it, and further improve the drilling efficiency and the durability of the drill bit 7.
