Description

Technical Field

[0001] This invention relates to the field of grouting pipe connection technology, specifically to a grouting joint connection device for coal mine grouting. Background Technology

[0002] Grouting is a commonly used construction technique in geotechnical engineering, and it is widely used in projects such as foundation reinforcement, seepage prevention, curtain wall and fissure plugging, slope reinforcement, and mining subsidence control.

[0003] The grouting pipe consists of two sections: one metal and the other a flexible plastic. During grouting, the metal section is inserted into the anchor hole for grouting, while the flexible plastic section carries the material. In coal mine grouting, these two sections need to be connected to grout the anchor hole. The current connection method typically involves the operator inserting one end of the metal pipe into the plastic pipe, binding the two sections together with wire, and then tightening the wire with pliers. However, this method relies on manual tightening, which has a limited limit. Furthermore, when inserting the metal pipe into the plastic pipe for the first time, the plastic needs to be heated to soften it for easier insertion. After the metal pipe is inserted and the plastic cools and sets, it is prone to loosening and separation after prolonged use and twisting. This results in poor connection stability between the two sections, potentially affecting the efficiency of coal mine grouting. Summary of the Invention

[0004] This invention proposes a grouting joint connection device for coal mine grouting, which solves the problems of the existing technology where the tightening force by hand has a certain upper limit, and the fact that when the metal pipe is first inserted into the plastic pipe, the plastic pipe needs to be heated to soften it to facilitate the insertion of the metal pipe. After the metal pipe is inserted into the plastic pipe, the plastic pipe cools and solidifies. After long-term use and twisting, it is easy for it to loosen and separate. The connection between the two grouting pipes is not stable, which can easily affect the grouting efficiency of coal mines.

[0041] The working principle and beneficial effects of this invention are as follows:

[0042] 1. In this invention, two fixing rings are fitted onto the insertion tube and locked with locking buckles. The operator drives the fixing screw to rotate. When the fixing screw rotates, it causes the fixing plate to contact the insertion tube, thereby fixing the two fixing rings onto the insertion tube. The operator also drives the fixing screw to cause the pulling plate to contact the delivery pipe. When the pulling plate contacts the delivery pipe, the limiting plate fixedly connected to the rotating ring presses against the delivery pipe, thereby fixing the delivery pipe onto the insertion tube.

[0043] 2. In this invention, a second motor installed on the slide carriage drives a rotating screw to rotate. When the rotating screw rotates, it moves within a screw hole on the drive block. As the rotating screw moves, it drives a pull ring closer to a fixed ring. When the pull ring moves, it drives a limiting plate to lock the conveying pipe and move synchronously, thereby inserting the insertion tube into the conveying pipe.

[0044] 3. In this invention, after the insertion tube and the delivery tube are connected, the operator ties the wire to the connection point and inserts both ends of the wire into the tightening frame. Then, the first motor on the motor frame drives the drive gear and the rotating gear to rotate. When the rotating gear rotates, it drives the tightening frame to rotate, thereby tightening the two ends of the wire together. When the wire is tightened, the first electric cylinder on the rotating gear drives the tightening frame to descend, thereby completely tightening the wire.

[0045] 4. In this invention, the cooperation between the fixing ring, the pull ring, the fixing plate, the pull plate, the locking buckle, the fixing mechanism, the pulling mechanism and the tightening mechanism can quickly connect and fix the insertion tube and the delivery tube, which improves the stability of the connection between the insertion tube and the delivery tube, makes it less likely to fall off, and improves the efficiency of coal mine grouting.

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0056] like Figures 1 to 7 As shown in the figure, this embodiment proposes a grouting joint connection device for coal mine grouting, including: a pipe 1 and a delivery pipe 2, and further including: a fixing ring 3, a pull ring 4, a fixing plate 5, a pull plate 6, a locking buckle 7, a fixing mechanism, a pulling mechanism, and a tightening mechanism. There are two fixing rings 3, which are rotatably connected to each other. There are two pull rings 4, which are rotatably connected to each other. There are two fixing plates 5, which are both set inside the two fixing rings 3. There are two pull plates 6, which are both set inside the two pull rings 4. There are two locking buckles 7, which are respectively set between the two fixing rings 3 and between the two pull rings 4. Through the cooperation between the fixing rings 3, pull rings 4, fixing plates 5, pull plates 6, locking buckles 7, fixing mechanism, pulling mechanism, and tightening mechanism, the pipe 1 and the delivery pipe 2 can be quickly connected and fixed, which improves the stability of the connection between the pipe 1 and the delivery pipe 2, makes it less likely to fall off, and improves the efficiency of coal mine grouting.

[0057] The device includes multiple fixing mechanisms, each mounted on two fixing rings 3 and two pull rings 4, for fixing the insertion tube 1 and the delivery tube 2. Each fixing mechanism includes a fixing screw 12, a support ring 13, anti-slip strips 14, and a limiting assembly. The fixing screw 12 is rotatably connected to the fixing plate 5, and the support ring 13 is fixedly connected to the fixing ring 3. The support ring 13 has a screw hole into which the fixing screw 12 is threaded. Two anti-slip strips 14 are provided, each fixedly connected to one of the two fixing plates 5. The limiting assembly is mounted on the pull rings 4 for limiting the delivery tube 2. The limiting assembly includes a rotating shaft 20, a rotating ring 21, a limiting plate 22, a toggle plate 23, a support plate 24, and a spring 25. The pull ring 4 has a limiting port, and the rotating shaft 20 is fixedly connected to the limiting port. The rotating ring 21... The rotating shaft 20 is rotatably connected to the limiting plate 22, which is fixedly connected to the fixed ring 3. The limiting plate 22 has multiple limiting grooves. The actuating plate 23 is fixedly connected to the rotating ring 21. The support plate 24 is fixedly connected to the pull ring 4. The spring 25 is fixedly connected between the actuating plate 23 and the support plate 24. Specifically, the two fixed rings 3 are put on the insertion tube 1 and locked by the locking buckle 7. The operator drives the fixing screw 12 to rotate. When the fixing screw 12 rotates, it drives the fixing plate 5 to contact the insertion tube 1, thereby fixing the two fixed rings 3 to the insertion tube 1. The operator drives the fixing screw 12 to drive the pull plate 6 to contact the delivery tube 2. When the pull plate 6 contacts the delivery tube 2, the limiting plate 22 fixedly connected to the rotating ring 21 presses against the delivery tube 2, thereby fixing the delivery tube 2 to the insertion tube 1.

[0058] The pulling mechanism is located between two fixed rings 3 and two pull rings 4, and is used to pull the distance between the fixed rings 3 and pull rings 4 closer. The pulling mechanism includes: a fixed block 8, a slide rod 9, a rotating screw 10, a drive block 11, and a drive assembly. Two fixed blocks 8 are provided, each fixedly connected to one of the two fixed rings 3. Two slide rods 9 are provided, each with a sliding hole, and are slidably disposed within the two sliding holes. Two rotating screws 10 are provided, each rotatably connected to one of the two pull rings 4. Two drive blocks 11 are provided, each fixedly connected to one of the two fixed rings 3. Each drive block 11 has a screw hole, and the two rotating screws 10 are threadedly connected to the screw holes. Two drive components are provided in the two screw holes, and the two drive components are respectively set on the two fixed rings 3. The drive components include: a slide 26 and a second motor 27. A sliding hole is opened on the drive block 11, and the slide 26 is slidably set in the sliding hole. The second motor 27 is set on the slide 26, and the output end of the second motor 27 passes through the slide 26 and is fixedly connected to the rotating screw 10. Specifically, the second motor 27 set on the slide 26 drives the rotating screw 10 to rotate. When the rotating screw 10 rotates, it moves in the screw hole opened on the drive block 11. When the rotating screw 10 moves, it drives the pull ring 4 to approach the fixed ring 3. When the pull ring 4 moves, it drives the limiting plate 22 to lock the delivery tube 2 and move synchronously, thereby inserting the insertion tube 1 into the delivery tube 2.

[0059] The tightening mechanism is located on a pull ring 4 near the top and is used to tighten the wire. The tightening mechanism includes a rotating gear 15, a drive gear 16, a first motor 17, a first electric cylinder 18, and a tightening frame 19. The rotating gear 15 is rotatably connected to the pull ring 4 near the top, and the drive gear 16 is rotatably connected to the pull ring 4 near the top. The drive gear 16 and the rotating gear 15 mesh with each other. The first motor 17 is mounted on the pull ring 4 via a motor frame. The output end of the first motor 17 passes through the motor frame and is fixedly connected to the drive gear 16. The first electric cylinder 18 is located on the rotating gear 19. On gear 15, tightening frame 19 is fixedly connected to the output end of first electric cylinder 18. Specifically, after the insertion tube 1 and delivery tube 2 are connected, the operator ties the wire to the connection point and inserts both ends of the wire into tightening frame 19. Then, the first motor 17 on the motor frame drives the drive gear 16 and rotating gear 15 to rotate. When rotating gear 15 rotates, it drives tightening frame 19 to rotate, thereby tightening the two ends of the wire together. When the wire is tightened, the first electric cylinder 18 on rotating gear 15 drives tightening frame 19 to descend, thereby completely tightening the wire.

[0060] In this embodiment, when it is necessary to connect the insertion tube 1 and the delivery tube 2, the operator heats the edge of the plastic delivery tube 2, causing the edge of the delivery tube 2 to expand. Then, the insertion tube 1 is inserted into the expanded delivery tube 2, and two fixing rings 3 are placed on the insertion tube 1 and locked with locking buckles 7. The operator then drives the fixing screw 12 to rotate. When the fixing screw 12 rotates, it causes the fixing plate 5 to contact the insertion tube 1, thereby fixing the two fixing rings 3 to the insertion tube 1. The operator drives the fixed screw 12 to move the pull plate 6 into contact with the conveying pipe 2. When the pull plate 6 contacts the conveying pipe 2, the limiting plate 22 fixedly connected to the rotating ring 21 presses against the conveying pipe 2, thereby fixing the conveying pipe 2 onto the insertion tube 1. Since the limiting plate 22 has a limiting groove and the end of the limiting plate 22 that contacts the conveying pipe 2 is relatively sharp, the conveying pipe 2 can be well fixed onto the insertion tube 1. Then, the second motor 27 set on the slide 26 drives the rotating screw 10 to rotate. When the screw 10 is rotated, it moves within the screw hole on the drive block 11. As the screw 10 rotates, it moves the pull ring 4 closer to the fixed ring 3. The pull ring 4 then moves the limiting plate 22 to lock the conveying pipe 2, thus inserting the insertion tube 1 into the conveying pipe 2. Because the conveying pipe 2 is only heated at the edge, the inner part of the conveying pipe 2 is deformed due to the direct insertion of the insertion tube 1, thus improving the tightness of the connection. After the insertion tube 1 and the conveying pipe 2 are connected, the operator ties a wire to the connection and secures both ends of the wire into the tightening bracket 1. Inside 9, the first motor 17 on the motor frame drives the drive gear 16 and the rotating gear 15 to rotate. When the rotating gear 15 rotates, it actuates the tightening frame 19 to rotate, thereby tightening the two ends of the wire together. When the wire is tightened, the first electric cylinder 18 on the rotating gear 15 drives the tightening frame 19 to descend, thereby completely tightening the wire. After a series of operations, the fixing plate 5 and the pull ring 4 are loosened, and the locking buckle 7 is opened, and then the device can be removed from the insertion tube 1.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
