Description

Technical Field

[0001] The utility model relates to the technical field of grouting equipment, in particular to a grouting device for mining reinforcement materials. Background Art

[0002] In the construction and use of mine tunnels, unfavorable geological conditions such as weakness and fragmentation are often encountered, which brings great difficulties to the management of the surrounding rock underground. Especially when affected by the advanced support pressure of the working face, the mining tunnel is subjected to large surrounding rock deformation, which seriously affects the safe and efficient production of the mine. Grouting is one of the important means to solve such problems. Grouting is widely used in many fields such as tunnel surrounding rock reinforcement and rock instability. At present, the materials used for grouting mainly include organic materials and inorganic materials.

[0003] Authorization announcement No. CN215057246U discloses a grouting reinforcement device for inorganic materials used in mining, the device comprising: a fixed tube extending along a first direction, the outer wall of the fixed tube being provided with a containing structure; the fixed tube having a first end and a second end which are opposite to each other along the first direction, the first end being an opening, and the fixed tube being provided with a first through hole on the wall surface close to the second end; a sealing member arranged in the containing structure, when the sealing member is arranged in the containing structure, the grouting reinforcement device is interference fit with the grouting borehole; a grouting tube, the grouting tube comprising a first part located in the fixed tube and a second part located outside the fixed tube, and a grouting hole is provided on the wall surface of the second part.

[0004] When grouting inside, it is often necessary to insert the grouting pipe into the wall. During the insertion process, due to the influence of the force, the soil blocks in the wall are easily squeezed into the head of the grouting pipe, causing blockage. The device has no good means to deal with this. For this reason, we propose a grouting device for mining reinforcement materials. Utility Model Content

[0010] Furthermore, the grouting device also includes a slide groove 1, and the upper and lower side surfaces of the grouting pipe are respectively transversely provided with a slide groove 1, and the two slide grooves 1 are respectively slidably connected with a slider 1, and the side surfaces of the two sliders 1 that are farther apart are respectively fixedly connected to the corresponding positions of the inner surface of the sliding ring, and the sliding ring is installed with a reinforcement mechanism.

[0013] The connecting screw rod 1 is designed so that the length of the connecting screw rod 1 outside the screw hole can be controlled, thereby adjusting the position of the screw. The screw is designed so that the grouting pipe can be supported and fixed, thereby ensuring that the posture of the grouting pipe is more stable. When fixing, first turn the screw rod 1 to adjust the screw to a suitable position, and then turn the knob 2 to turn the screw, thereby screwing the screw into the wall to complete the fixation.

[0014] Furthermore, the reinforcement mechanism also includes a knob 1, and the knob 1 is respectively sleeved on a position of each screw rod 1 close to the connecting block 2.

[0027] The liquid inlet 12 is designed so that when the right side of the grouting pipe 1 is blocked, the slurry enters the liquid inlet 12, thereby increasing the pressure of the liquid in the liquid inlet 12 by reducing the pipe diameter, and pushing the movable pipe 14 to move to the right by the suddenly increased pressure, thereby puncturing the soil block blocking the right side of the grouting pipe 1, thereby breaking the soil block, and the circular hole is designed so that when the movable pipe 14 is inserted into the soil block, a high-pressure liquid flow is injected into the interior of the soil block through the circular hole, thereby accelerating the decomposition of the soil block.

[0028] The grouting device also includes a spring 13 . The left ends of the two moving tubes 14 are fixedly connected to the right ends of the spring 13 , and the left ends of the two springs 13 are fixedly connected to corresponding positions in the middle of the liquid inlet channel 12 .

[0029] The spring 13 is designed so that when the grouting pipe 1 is unblocked and the pressure inside the pipe decreases, the moving pipe 14 is pulled back to its original position.

[0030] The grouting device also includes a slide groove 2. The upper and lower side surfaces of the grouting pipe 1 are respectively provided with a slide groove 2 transversely. The two slide grooves 2 are respectively slidably connected with sliders 3.

At this time, the movable tube 14 is pushed out of the liquid inlet channel 12, so that the circular hole is opened, thereby injecting high-pressure liquid flow into the interior of the soil block through the circular hole, thereby accelerating the decomposition of the soil block. First, turn the screw 6 through the knob 7 to adjust the screw 9 to the appropriate position, and then turn the knob 2 10 to turn the screw 9, thereby screwing the screw 9 into the wall to complete the fixation.
