Description

Technical Field

[0001] The present invention relates to the technical field of grouting reinforcement, and specifically provides a grading grouting reinforcement device and method for mine inorganic materials. Background Technique

[0002] Mine inorganic materials are non-metallic materials widely used in mine engineering, including concrete, cement, etc. They mainly have characteristics such as high strength, corrosion resistance, and high temperature resistance. The core objective is to inject grouting materials into the cracks and pores of the wellhead through pressure to achieve the purpose of stable reinforcement, effectively improve the stability of the wellhead, reduce the risk of wellhead collapse, and provide an important guarantee for the safe production of the mine.

[0003] The patent with the publication number CN220581046U discloses a directional grouting reinforcement device for broken roof in coal mines. This patent provides a directional grouting reinforcement device for broken roof in coal mines that can protect the roof during grouting to prevent the roof from falling and injuring workers. A directional grouting reinforcement device for broken roof in coal mines includes a base, a connecting rod, a support frame, a buckle, a sliding member, etc. There are two bases. The connecting rod is slidably connected between the bases. The support frame is rotatably connected to the connecting rod. The upper side of the support frame is connected with a buckle. The upper sides of the bases are both slidably connected with sliding members. By starting the air cylinder in this patent, the push rod moves upward, and the support pipe moves upward to contact the protection plate, so that the protection plate rotates to be parallel to the broken roof, achieving the effect of being able to protect the roof during grouting and prevent the roof from falling and injuring workers.

[0004] However, the current directional grouting reinforcement device for broken roof in coal mines has the following problems: When the directional grouting reinforcement device for broken roof in coal mines is in use, since the slurry is relatively thick and difficult to enter the cracks in the mine wellhead for bonding, and the slurry is relatively thin and difficult to carry out surface reinforcement of the wellhead, it further leads to poor reinforcement effect inside the gaps of the mine wellhead. Therefore, we propose a grading grouting reinforcement device and method for mine inorganic materials. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

A number of connecting pieces 7 are respectively fixed on the right sides of the outer walls of the two material pipes 6. The bottom surfaces of the number of connecting pieces 7 are fixedly connected to the top surface of the trolley 1. In the middle of the top surface of the circular cover 4, a circular shell 8 is fixed. The circular shell 8 is located between the two electric telescopic rods 3. A motor 9 is fixedly installed at the top of the inner wall of the circular shell 8. A thick rod 10 penetrates and is rotatably installed in the middle of the top surface of the circular cover 4. The top surface of the thick rod 10 is fixedly connected to the bottom surface of the rotating shaft of the motor 9. At the top end inside the circular cover 4, a hanging ring 11 is fixed. The inner wall of the hanging ring 11 is rotatably connected to the outer wall of the top of the thick rod 10. Three inclined scraping plates 12 are fixed to the bottom of the outer wall of the thick rod 10. One end of each of the two material pipes 6 away from the double-hole block 5 is respectively provided with a connection port. A number of strip-shaped openings are formed in the outer wall of the circular shell 8. Circular grooves are formed on the top surfaces of the three inclined scraping plates 12. The material pipe 6 transports the fine slurry into the foundation pit. The rotating shaft of the motor 9 drives the thick rod 10 to rotate forward. The thick rod 10 rotates forward in the hanging ring 11, enabling the thick rod 10 to rotate stably. The thick rod 10 drives the inclined scraping plates 12 to rotate forward. The inclined scraping plates 12 scrape the fine slurry flat, allowing the fine slurry to penetrate into the cracks at the mine entrance. The material pipe 6 transports the thick slurry into the foundation pit. The electric telescopic rod 3 slowly drives the circular cover 4 to move upward. The circular cover 4 slowly drives the thick rod 10 to move upward. The thick rod 10 drives the inclined scraping plates 12 to move upward. The inclined scraping plates 12 slowly rotate upward. The inclined scraping plates 12 smooth the thick slurry in the foundation pit, enabling the fine slurry to penetrate into the cracks for bonding. The thick slurry reinforces the surface of the mine entrance in the foundation pit, allowing the fine slurry and the thick slurry to reinforce the mine entrance in a graded manner, avoiding the situation that it is difficult to reinforce the inside of the gaps at the mine entrance when the grouting reinforcement device reinforces the mine entrance, resulting in poor reinforcement effect. A push frame 15 is fixedly installed on the right side of the top surface of the trolley 1. A lower strip plate 16 penetrates and is fixed to the bottom surface of the push frame 15. The lower strip plate 16 is located on the right side of the trolley 1. A chamfered plate 17 is fixed to the bottom surface of the lower strip plate 16. The chamfered plate 17 scrapes the surface of the thick slurry in the foundation pit, making the thick slurry on the surface of the mine entrance more dense; A material discharging device 13 is arranged on the inner wall of the circular grooves of the three inclined scraping plates 12. The material discharging device 13 scrapes off the mining inorganic materials at the discharging ports of the two material pipes 6. An anti-adhesion device 14 is arranged on the inner wall of the material discharging device 13. The anti-adhesion device 14 is used to scrape off the mining inorganic materials attached to the inner wall of the circular cover 4.

[0024] During the reinforcement of the mine entrance, if the slurry is too thick, it is difficult to enter the cracks in the mine entrance for bonding, and if the slurry is too thin, it is difficult to reinforce the surface of the mine entrance. When using the equipment, the operator digs a foundation pit at the edge of the mine entrance. The operator uses the push frame 15 to push the trolley 1 to the mine entrance, aligns the round cover 4 with the foundation pit, and the connecting piece 7 fixes the two material pipes 6. The operator pours thick slurry into the connection port of one material pipe 6 and thin slurry into the connection port of the other material pipe 6. The trolley 1 supports the inverted U-shaped frame 2. The operator starts the electric telescopic rod 3 on the inverted U-shaped frame 2, and the telescopic end of the electric telescopic rod 3 begins to move downward. The telescopic end of the electric telescopic rod 3 drives the round cover 4 to move downward, the round cover 4 drives the double-hole block 5 to move downward, and the double-hole block 5 drives the material pipe 6 to move downward. The round cover 4 contacts the bottom of the foundation pit, and the material pipe 6 transports the thin slurry into the foundation pit. At the same time, the round cover 4 supports the round shell 8. The operator starts the motor 9 in the round shell 8, and the rotating shaft of the motor 9 starts to rotate forward. The rotating shaft of the motor 9 drives the thick rod 10 to rotate forward. The thick rod 10 rotates forward in the round cover 4. The round cover 4 supports the hanging ring 11, and the thick rod 10 rotates forward in the hanging ring 11 to enable the thick rod 10 to rotate stably. The thick rod 10 drives the inclined scraper 12 to rotate forward, and the inclined scraper 12 levels the thin slurry to allow the thin slurry to penetrate into the cracks in the mine entrance. When the cracks are filled with the thin slurry, the material pipe 6 transports the thick slurry into the foundation pit. The operator starts the electric telescopic rod 3, and the telescopic end of the electric telescopic rod 3 begins to move slowly upward. The electric telescopic rod 3 slowly drives the round cover 4 to move upward, the round cover 4 slowly drives the thick rod 10 to move upward, the thick rod 10 drives the inclined scraper 12 to move upward, and the inclined scraper 12 slowly rotates upward. The inclined scraper 12 levels the thick slurry in the foundation pit, enabling the thin slurry to penetrate into the cracks for bonding, and the thick slurry reinforces the surface of the mine entrance in the foundation pit, allowing the thin slurry and the thick slurry to reinforce the mine entrance in a graded manner, preventing the inside of the gap at the mine entrance from being difficult to reinforce when the equipment is in use, thereby avoiding the problem of poor reinforcement effect caused by the difficulty in reinforcing the inside of the gap at the mine entrance when the grouting reinforcement device reinforces the mine entrance. When the reinforcement is completed, the operator pushes the push frame 15 to move leftward. The push frame 15 drives the lower strip 16 to move leftward, and the lower strip 16 drives the chamfered plate 17 to move leftward. The chamfered plate 17 levels the surface of the thick slurry in the foundation pit to make the thick slurry on the surface of the mine entrance more dense.

[0025] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, three vertical rods 131 are respectively fixed on the inner walls of the circular grooves of the three inclined scraping plates 12. A circular ring 132 is fixed on the top surfaces of the three vertical rods 131. Three connecting blocks 133 are fixed on the top surface of the circular ring 132. Three L-shaped rods 134 are respectively fixed on the inner walls of the three connecting blocks 133. Three rectangular plates 135 are respectively embedded at the ends of the three L-shaped rods 134 away from the three connecting blocks 133. The bottom surfaces of the discharge ports of the two rectangular plates 135 are on the movement trajectories of the outer walls of the three rectangular plates 135. During the rotation of the rectangular plates 135, the rectangular plates 135 scrape off the slurry accumulated at the discharge port of the material pipe 6, preventing a large amount of slurry from accumulating at the discharge port of the material pipe 6 when the grouting reinforcement device reinforces the mine entrance, which may cause poor discharging effect of the equipment.

[0026] At the ends of the three L-shaped rods 134 away from the three rectangular plates 135, ring concave plates 136 are fixed. Three notches are formed on the outer walls of the ring concave plates 136. A number of triangular blocks 137 are fixed on the top surfaces of the ring concave plates 136. A straight rod 138 is fixed at the top end of the round cover 4. The straight rod 138 is located on the right side of the hanging ring 11. A spring piece 139 is embedded at the bottom surface of the straight rod 138. The outer wall of the spring piece 139 is on the movement trajectories of the number of triangular blocks 137. During the rotation of the triangular blocks 137, the triangular blocks 137 hit the spring piece 139, causing the spring piece 139 to deform. The triangular blocks 137 generate vibrations, and the triangular blocks 137 transmit the vibrations to the rectangular plates 135. The rectangular plates 135 vibrate to scrape off the slurry on the discharge port of the material pipe 6, preventing the slurry from adhering to the discharge port of the material pipe 6 when the grouting reinforcement device reinforces the mine entrance, which may cause blockage of the discharge port of the material pipe 6.

[0027] Straight frames 141 are respectively fixed on the inner walls of the three notches of the ring concave plates 136. Three support frames 142 are respectively fixed on the bottom surfaces of the three straight frames 141. The ends of the three support frames 142 away from the three straight frames 141 are fixedly connected to the outer walls of the three vertical rods 131. Three double-arc plates 143 are respectively fixed at the ends of the three straight frames 141 away from the ring concave plates 136. Three vertical plates 144 are respectively embedded on the sides of the three double-arc plates 143 away from the three straight frames 141. The outer walls of the three vertical plates 144 are in sliding contact with the inner wall of the round cover 4. During the rotation of the vertical plates 144, the vertical plates 144 scrape off the slurry sputtered on the wall surface of the round cover 4, preventing a large amount of slurry from accumulating on the wall surface of the round cover 4 when the grouting reinforcement device reinforces the mine entrance, which may cause waste of the slurry.

[0028] On the outer walls of the three straight frames 141, three U-shaped frames 145 are respectively fixed. On the outer walls of the three U-shaped frames 145, three short rods 146 are respectively fixed. At the ends of the three short rods 146 far away from the three U-shaped frames 145, three inclined plate pieces 147 are respectively fixed. The three inclined plate pieces 147 are located below the discharge ports of the two material pipes 6. The slurry discharged from the material pipes 6 contacts the inclined plate pieces 147. During the rotation of the inclined plate pieces 147, the inclined plate pieces 147 evenly spread the slurry in the foundation pit, avoiding the problem that when the grouting reinforcement device reinforces the mine entrance, the uneven discharge of the equipment causes poor reinforcement effect of the equipment.

[0029] A reinforcement method for a grading grouting reinforcement device of mine inorganic materials includes the following steps: S1. Dig a circle of foundation pit at the edge of the mine entrance, push the trolley 1 to the mine entrance, align the round cover 4 with the foundation pit, and connect thick slurry and thin slurry to the connection ports of the two material pipes 6 respectively. S2. The material pipe 6 transports the thin slurry into the foundation pit, and the inclined scraper 12 scrapes the thin slurry flat, allowing the thin slurry to penetrate into the cracks of the mine entrance. S3. The material pipe 6 transports the thick slurry into the foundation pit, and the inclined scraper 12 smooths the thick slurry in the foundation pit. S4. The rectangular plate 135 scrapes off the slurry accumulated at the discharge port of the material pipe 6. S5. The triangular block 137 impacts the spring piece 139, and the triangular block 137 transmits vibration to the rectangular plate 135. The rectangular plate 135 vibrates to scrape off the slurry on the discharge port of the material pipe 6. S6. During the rotation of the vertical plate 144, the vertical plate 144 shovels off the slurry sputtered on the wall surface of the round cover 4. S7. The slurry discharged from the material pipe 6 contacts the inclined plate piece 147, and the inclined plate piece 147 evenly spreads the slurry in the foundation pit. S8. Driven by the push frame 15, the lower strip plate 16 moves leftward, the lower strip plate 16 drives the chamfered plate 17 to move leftward, and the chamfered plate 17 smooths the surface of the thick slurry in the foundation pit.

[0030] While the thick rod 10 drives the inclined scraper 12 to rotate forward, the inclined scraper 12 drives the vertical rod 131 to rotate forward, the vertical rod 131 drives the ring 132 to rotate forward, the ring 132 drives the connecting block 133 to rotate forward, the connecting block 133 drives the L-shaped rod 134 to rotate forward, and the L-shaped rod 134 drives the rectangular plate 135. During the rotation of the rectangular plate 135, the rectangular plate 135 scrapes off the slurry accumulated at the discharge port of the material pipe 6, preventing a large amount of slurry from accumulating at the discharge port of the material pipe 6 when the equipment is in use, thus avoiding the problem that when the grouting reinforcement device reinforces the mine entrance, a large amount of slurry accumulated at the discharge port of the material pipe 6 causes poor discharge effect of the equipment.

[0031] While the connecting block 133 drives the L-shaped rod 134 to rotate clockwise, the L-shaped rod 134 drives the ring concave plate 136 to rotate clockwise, and the ring concave plate 136 drives the triangular block 137 to rotate clockwise. At the same time, the circular cover 4 supports the straight rod 138, the straight rod 138 supports the spring piece 139. During the rotation of the triangular block 137, the triangular block 137 impacts the spring piece 139, causing the spring piece 139 to deform, generating vibration on the triangular block 137. The triangular block 137 transmits the vibration to the ring concave plate 136, the ring concave plate 136 transmits the vibration to the L-shaped rod 134, and the L-shaped rod 134 transmits the vibration to the rectangular plate 135. The rectangular plate 135 vibrates to scrape the slurry at the discharge port of the material pipe 6, preventing the slurry from adhering to the discharge port of the material pipe 6 during the use of the equipment, thus avoiding the problem that the discharge port of the material pipe 6 is blocked due to the adhesion of the slurry at the discharge port of the material pipe 6 when the grouting reinforcement device reinforces the mine entrance.

[0032] While the L-shaped rod 134 drives the ring concave plate 136 to rotate clockwise, the ring concave plate 136 drives the straight frame 141 to rotate clockwise, the straight frame 141 drives the support frame 142 to rotate clockwise, and the support frame 142 holds the straight frame 141 to rotate, keeping the straight frame 141 stable during the rotation. At the same time, the straight frame 141 drives the double arc plate 143 to rotate clockwise, and the double arc plate 143 drives the vertical plate 144 to rotate clockwise. During the rotation of the vertical plate 144, the vertical plate 144 shovels the slurry sputtered on the wall surface of the circular cover 4, preventing a large amount of slurry from accumulating on the wall surface of the circular cover 4 during the use of the equipment, thus avoiding the problem of slurry waste caused by the accumulation of a large amount of slurry on the wall surface of the circular cover 4 when the grouting reinforcement device reinforces the mine entrance.

[0033] While the ring concave plate 136 drives the straight frame 141 to rotate clockwise, the straight frame 141 drives the loop frame 145 to rotate clockwise, the loop frame 145 drives the short rod 146 to rotate clockwise, and the short rod 146 drives the inclined plate 147 to rotate clockwise. During the feeding process of the material pipe 6, the slurry discharged from the material pipe 6 contacts the inclined plate 147. During the rotation of the inclined plate 147, the inclined plate 147 evenly spreads the slurry in the foundation pit, preventing the uneven discharge of the equipment during the use of the equipment, thus avoiding the problem that the uneven discharge of the equipment causes poor reinforcement effect when the grouting reinforcement device reinforces the mine entrance.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
