Description

Technical Field

[0001] This utility model belongs to the field of coal mine water plugging technology, specifically a coal mine water plugging grouting device. Background Technology

[0002] Coal mine engineering is a comprehensive project involving the mining and utilization of coal resources. It covers multiple aspects, from mine construction and coal mining to coal processing and environmental protection. In coal mine engineering, grouting devices are often used. The main purpose of grouting to plug water is to prevent groundwater from rushing into the mine, avoiding equipment damage, production interruption and casualties. By sealing the water outlet through grouting technology, the flow path of water can be effectively slowed down, reducing its threat to the lower coal roadways. This is one of the important guarantee measures for safe production in coal mines.

[0003] Utility model patent application publication number 202420001779.8 discloses a grouting device for water plugging in coal mine geology, including a shell, a grouting pipe, and a water suction structure. The grouting pipe is located inside the shell, with one end connected to a grouting supply device and the other end serving as the grout outlet. The water suction structure includes a water pump and a water suction pipe, which is installed inside the shell. One end of the water suction pipe is the water suction port, and the water suction port and the grout outlet of the grouting pipe are located at the same end. The end of the water suction pipe away from the water suction port is connected to the water pump, which is installed inside the shell. This design achieves the effect of preventing the sewage in the foundation fissures from mixing with the grout and reducing the grout concentration during grouting of the foundation fissures in coal mines.

[0004] As can be seen from the aforementioned patent, there is a coal mine water plugging grouting device, but it still has shortcomings in actual use. The most obvious one is that after grouting and water plugging is usually done using grouting pipes, the surface of the grouting pipes is prone to adhering to sticky impurities such as mud and sewage. During the next grouting, these impurities may dilute the grout, reducing its strength and viscosity, thereby affecting the filling effect and sealing performance of the grouting. Usually, workers need to use cleaning tools to wipe and clean the impurities. When there are many sticky and sticky impurities, workers need to spend a lot of time cleaning, which reduces the efficiency of the grouting device. Therefore, we propose a coal mine water plugging grouting device. Utility Model Content

The electric telescopic rod 250 drives the grouting pipe 240 to move longitudinally, performing grouting and water plugging operations on the coal mine through the grouting pipe 240. Then, when the electric telescopic rod 250 retracts the grouting pipe 240, the motor 110 is started. The motor 110 drives the gear 111 to rotate, which in turn drives the gear ring 132 and the rotating plate 130 to rotate. The rotating plate 130 drives the rotating ring 121 to rotate within the annular groove 120. The rotating plate 131, through the guide groove 131, drives the connecting rod 153 to move horizontally. 153 drives the connecting block 152 and the slide rod 150 to move, and the slide rod 150 drives the arc-shaped scraper 160 to move horizontally. The arc-shaped scraper 160 contacts the surface of the grouting pipe 240, so that the surface of the grouting pipe 240 can be cleaned when the pipe is raised and lowered. When disassembling the arc-shaped scraper 160, the operator restricts the rotation of the arc-shaped scraper 160 and drives the slide rod 150 to rotate. The slide rod 150 pushes the arc-shaped scraper 160 to move through the threaded groove 151 and the threaded hole 161, thereby realizing the disassembly of the arc-shaped scraper 160 and completing the use of the device.
