Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine construction, in particular to a novel grouting device. Background Art
[0002] There is often groundwater underground in mines. In order to ensure that the underground working face of the mine is not invaded by groundwater, it is necessary to build closed walls to prevent leakage and seepage. Plastering can reinforce the rock or coal seams in coal mine tunnels, chambers and other places to prevent them from collapsing or collapse, and improve the stability of the construction area. There are often harmful gases such as flammable gases underground in coal mines. Closed walls and plastering can prevent these gases from leaking into the working face or ventilation tunnels, ensuring the safety of air quality in the mine. Closed walls and plastering can effectively isolate fire sources and smoke, reduce the possibility of fire spread, and improve fire safety underground in mines. Closed walls and plastering can protect the safety of equipment, pipelines and workers in the mine, and avoid accidents or collapses that lead to casualties.
[0003] Traditional underground wall construction mainly relies on manual wall plastering. During long-term work, it is easy to cause strain on the workers' arms and shoulders, and even the phenomenon of "tennis elbow". Although the spraying machine can solve this problem, the underground environment is complex and the space is small. When the traditional spraying machine is in use, the hose on the spraying machine is easily bent, affecting normal spraying and reducing construction efficiency. Utility Model Content

[0023] The connecting assembly 2 includes a feed pipe 21 fixedly connected to the output end of the shotcrete machine body 1, the end of the feed pipe 21 away from the shotcrete machine body 1 is fixedly connected to a feeding pipe 22, the interior of the feed pipe 21 is connected to the interior of the feeding pipe 22, the output end of the shotcrete machine body 1 is fixedly connected to the input end of the feed pipe 21 through a flange, the end of the feeding pipe 22 away from the feed pipe 21 is fixedly connected to the interior of the shotcrete machine body 1, the surface of the feeding pipe 22 is fixedly connected to a support frame 23, both ends of the outer surface of the feeding pipe 22 are fixedly sleeved with a first fixing ring 24, the outer surface of the feeding pipe 22 is fixedly sleeved with a bellows 25, the number of the bellows 25 is two, the outer surface of the bellows 25 is fixedly installed with a clamp 26, the end of the bellows 25 away from the feeding pipe 22 is fixedly connected to a connecting pipe 27, the connecting pipe 27 The end of the surface away from the feeding pipe 22 is provided with a thread, and the hose connector 3 is fixedly installed on the outer surface of the connecting pipe 27 through the thread, and the outer surfaces of the bellows 25 are sleeved with clamps 26 at both ends, and the bellows 25 is fixedly sleeved with the outer surface of the connecting pipe 27 through the clamps 26, and the outer surface of the connecting pipe 27 is fixedly sleeved with a sleeve 28, and the outer surface of the sleeve 28 is fixedly sleeved with a second fixing ring 29. By arranging the feeding pipe 21 and the feeding pipe 22, etc., two discharge hoses 4 and spray guns 5 can be installed at the same time. Therefore, when plastering the wall, the plastering work of a large area can be completed quickly, which effectively reduces the labor intensity and time cost of the employees, and the sprayed mortar is uniform, smooth and dense, which can better ensure the strength and flatness of the wall, improve the operation quality, improve the work efficiency, and enhance the adaptability;
[0024] The surface of the second fixing ring 29 is fixedly connected with the first rotating plate 210, and each surface of the second fixing ring 29 is fixedly installed with two first rotating plates 210. The first rotating plate 210 is fixedly installed on the surface of the second fixing ring 29 by bolts. The surface of the first rotating plate 210 is rotatably connected with the second rotating plate 211, and the second rotating plate 211 is fixedly connected to the surface of the first fixing ring 24 by bolts. The end of the second rotating plate 211 away from the first rotating plate 210 is fixedly connected to the surface of the first fixing ring 24. By setting a rotatable structure between the connecting pipe 27 and the feeding pipe 22 to cooperate with the bending of the bellows 25, it is possible to avoid slurry blockage caused by twists and turns at the interface of the discharge hose 4. Reducing slurry blockage can reduce the stress and loss on the equipment and extend the service life of the spraying device.
[0025] When working, the spraying machine body 1 is moved to the specified position, and then the two hose connectors 3 are respectively connected to the two connecting pipes 27, and then the slurry is placed in the spraying machine body 1. The staff holds the spray gun 5 to spray the slurry to the specified area. When the spray gun 5 drives the discharge hose 4 to move, the discharge hose 4 drives the connecting pipe 27 to rotate through the hose connector 3. At this time, after the bellows 25 is bent, the slurry inside the feed pipe 22 can normally enter the connecting pipe 27. When the bellows 25 is complete, the first rotating plate 210 and the second rotating plate 211 also rotate. Through the bendability of the bellows 25 and the rotatable structure between the connecting pipe 27 and the feed pipe 22, the interface of the discharge hose 4 can be prevented from being blocked by the slurry due to twists and turns. Reducing the slurry blockage can reduce the stress and loss of the equipment and extend the service life of the spraying device.
