The fixing frame 203 is fixedly connected to the top of the housing 101, and the nozzle 202 is fixedly connected to the end of the delivery pipe 201; the other end of the delivery pipe 201 is fixed with the drive pump 207, which is fixed to the slurry storage tank 205. Inside 05, the drive pump 207 drives the repair slurry in the slurry storage tank 205 into the delivery pipe 201. The slurry storage tank 205 is located inside the tank body 101 and stores the repair slurry. The repair slurry is sprayed out from the nozzle 202 through the delivery pipe 201 and sprayed onto the parts of the roadway that need repair. The cleaning component 300 includes a telescopic pipe 301, a suction plate 302, a suction pump 304, and a water storage tank 306. The water storage tank 306 is located inside the tank body 101 and is used to temporarily store the slurry cleaned from the roadway. The water is absorbed by a pump fixed inside the water storage tank 306. The water is drawn into the water storage tank 306 by the suction pump 304, which is fixedly connected to the telescopic pipe 301. The suction plate 302 is fixed to the other end of the telescopic pipe 301. When water is encountered in the tunnel, the staff picks up the suction plate 302 and places it in the water. The water enters the water storage tank 306 through the telescopic pipe 301. The extendable part of the telescopic pipe 301 is located outside the tank body 101. The telescopic pipe 301 can be extended by pulling it.

[0039] Preferably, a stirring motor 204 is fixed inside the slurry storage tank 205, and multiple stirring rods 206 are fixed on the rotating shaft of the stirring motor 204; the stirring motor 204 is fixed at the bottom of the slurry storage tank 205; the stirring rods 206 are rectangular rods, and the stirring motor 204 stirs the repair slurry in the slurry storage tank 205. During the repair of the roadway, if the repair slurry is used up, the raw material of the repair slurry can be put into the slurry storage chamber through the feed port 103, and the stirring motor 204 drives the stirring rods 206 to rotate to mix the repair slurry.

[0040] Preferably, the water pump 304 can discharge the water stored in the water storage tank 306 through the telescopic pipe 301. When the water in the slurry storage chamber is insufficient, the telescopic pipe 301 is extended from the feed port 103 into the slurry storage chamber to mix the water in the water storage chamber with the slurry, so that the repair slurry in the slurry storage chamber is kept in a paste state. When repairing the roadway, the paste-like repair slurry can penetrate into the cracks and fill them.

[0041] Preferably, the repair grout is composed of cement, fine sand powder and admixtures. The admixtures enable the repair grout to cure quickly. After being sprayed into the crack, the repair grout can fill the crack. The repair grout is sticky, so when repairing cracks at the top of the tunnel, the repair grout can stick to the crack without falling off. After the repair grout cures, the repair of the crack is completed.

[0042] Preferably, a fixing plate 303 is fixedly connected to the outer wall of the housing 101, and the fixing plate 303 is located on the side wall near the water storage tank 306; the fixing plate 303 is a rectangular plate with an arc-shaped slot, and the water suction plate 302 is clamped on the fixing plate 303. When there is no water accumulation in the tunnel and cleaning is required, the water suction plate 302 is fixed on the fixing plate 303; when water accumulation needs to be cleaned, the water suction plate 302 is removed from the fixing plate 303.

[0043] Preferably, the water suction plate 302 is a rubber disc with an open bottom.

The telescopic tube 301 passes through the connecting block 307 and the connecting block 307 is used to fix the telescopic tube 301 to the tank 101.

[0046] Preferably, two telescopic pipes 301 are fixed on the connecting block 307, and a water pump 304 is fixed to the end of each telescopic pipe 301. The water pumps 304 are fixed in the water storage tank 306. The water accumulation is mainly in the pits caused by vehicles running over the road surface. When cleaning the water accumulation in the road, the two water pumps 304 can work at the same time. Two workers can operate the telescopic pipes 301 to clean the water accumulation in different locations in the road, thereby improving the efficiency of cleaning the water accumulation.

[0047] Preferably, the nozzle 202 is detachably fixed to the hose. The nozzle 202 can be removed by twisting it. The nozzle 202 can be replaced from a single outlet nozzle to a multi-outlet nozzle. The multi-outlet nozzle 202 can spray the repair slurry onto the tunnel walls and tunnel top. After the repair slurry cures, it can form a protective layer, which can prevent the tunnel wall plaster from peeling off and cracking.

[0048] Preferably, the side wall of the box body 101 is provided with a round hole that connects to the water storage tank 306. A drain pipe 305 is fixed to the outside of the box body 101. The drain pipe 305 is connected to the inside of the water storage tank 306 through the round hole. When the water storage tank 306 stores water, the water temporarily stored in the water storage tank 306 is discharged through the drain pipe 305. When the water in the water storage tank 306 is discharged, the box body 101 is moved to the drain pipe 305 in the alleyway so that the discharged water is discharged from the drain pipe 305 in the alleyway.

[0049] Preferably, a connecting pipe 208 is fixed on the nozzle 202, and the connecting pipe 208 is threaded to the end of the conveying pipe 201; a rotating roller 209 is rotatably connected to the fixing frame 203. The rotating roller 209 is a cylindrical tube, and the conveying pipe 201 is wound around the rotating roller 209. When repairing cracks or pits in the tunnel, the conveying pipe 201 is wound up and down by rotating the rotating roller 209.

[0050] Preferably, the conveying pipe 201 is a pouring hose. When the conveying pipe 201 is wound around the rotating roller 209, the internal channel of the conveying pipe 201 will not deform, so that the concrete slurry can flow in the conveying pipe 201. The inner wall of the conveying pipe 201 has good wear resistance and can directly contact the concrete slurry.

[0051] Preferably, a support rod 104 is fixed to the side wall of the box 101. The support rod 104 is a rectangular rod. The support rod 104 is fixed to the side wall of the box 101 by bolts. The box 101 is moved by pushing the support rod 104.

[0052] In practical use, a multifunctional coal mine roadway repair device according to an embodiment of this application is as follows:

[0053] First, the repair slurry is placed into the slurry storage tank 205 through the feed inlet 103. The tank 101 moves forward in the coal mine roadway. When a repair area is found, the nozzle 202 is moved closer to the crack by pulling the delivery pipe 201. The drive pump 207 drives the repair slurry in the storage chamber to be sprayed out from the nozzle 202 through the delivery pipe 201. The sprayed repair slurry repairs the cracks and pits in the coal mine roadway. During the movement of the tank 101, if there is water accumulation on the coal mine roadway surface, the workers remove the water suction plate 302 from the tank 101 and place it on the road surface. In the water accumulation, the water is sucked into the water storage tank 306 through the expansion pipe 301 by the water suction pump 304. After the water storage tank 306 is full, the water in the water storage tank 306 is discharged into the drainage pipe 305 in the roadway through the drainage pipe 305. When the repair slurry in the slurry storage tank 205 is used up, the raw material of the repair slurry can be poured into the slurry storage chamber. The water in the water storage tank 306 is transported into the slurry storage chamber by the water suction pump 304 through the water suction plate 302. Driven by the stirring motor 204, the stirring rod 206 stirs the slurry to make the repair slurry fully mixed. The mixed repair slurry is then sprayed out through the nozzle 202.
