Description

Technical Field

[0001] The present invention relates to the technical field of fissure plugging, and specifically to a fissure plugging device for overburden separation grouting. Background Art

[0002] The overburden separation grouting technology refers to injecting specific materials to fill and solidify the cracks and discrete surfaces in the rock mass, enhancing the stability and bearing capacity of the rock mass. During the hardening process of the slurry water, due to the dehydration of the slurry water, shrinkage occurs, or due to the influence of temperature differences between high and low temperatures, uneven expansion and contraction occurs, resulting in cracks. For this, a repair agent needs to be used to repair the cracks.

[0003] After retrieval, in the application document of a highway crack repair device for traffic engineering proposed in Application No. 202311346366.X, the machine body is pushed to the position of the crack to be repaired. The shoveling plates around the device box will make the bottom end contact the ground under the push of the first spring, which is more convenient for operating in line with different terrains. While pushing the handle, control the steering of the handle, so that the tip block position of the device box always moves along the trajectory of the crack. By driving the third gears on both sides to rotate through the first gear, the second gear can also rotate synchronously with the first gear. The device box always moves in a position parallel to the direction of the second rollers on both sides, which is more conducive to direction control. At the same time, this front-narrow-and-rear-wide machine body design is also more convenient for the operator to view the crack trend at the front end, and the operation is more accurate and efficient.

[0004] Although the above application meets the user's usage requirements to a certain extent, there are still certain defects in the usage process. The specific problems are as follows. Based on this, during the plugging process, it is necessary to continuously move the fuselage so that the discharge pipe is at the top of the crack, resulting in a large labor intensity of personnel and a low crack plugging efficiency. At the same time, during the plugging process, the repair agent is easy to splash out, resulting in waste of the repair agent and easy to affect the surrounding area of the crack. The present invention designs a fissure plugging device for overburden separation grouting to solve the above problems. Summary of the Invention

The movable end of the adjustable telescopic rod 705 is fixedly connected to the driving rod 706; At the top of the belt connection mechanism 702, a second spur gear connection mechanism 708 is fixedly connected. At the bottom of one end of the second spur gear connection mechanism 708, an adjustment threaded cylinder 709 is installed by screws. Inside the adjustment threaded cylinder 709, a reciprocating lead screw 710 is connected by threads. Inside the reciprocating lead screw 710, a limiting rod 711 is slidably connected. The limiting rod 711 is installed by screws at one end of the top of the cart 1. At the bottom of the reciprocating lead screw 710, a moving rod 712 is provided. One end of the moving rod 712 is rotatably connected to a moving disk 713. The moving disk 713 is fixedly connected to the movable end of the adjustable telescopic rod 705. The second spur gear connection mechanism 708 includes two second spur gears. The gear ratio of the two second spur gears is 1:4. The smaller second spur gear is fixedly connected to the adjustment threaded cylinder 709. The moving disk 713 has the same diameter as the mounting plate 703. The distance between the center of the adjustable telescopic frame 704 and the center of the mounting plate 703 is 3 cm.

[0023] After the personnel move the cart 1 to a suitable position, the connecting rod 511 contacts the guide plate 504, and the spring telescopic column 503 is in a compressed state. Subsequently, through the adjustment of the adjustable telescopic frame 704 by the personnel, the vibrating cylinder 707 is moved to a suitable position. The personnel turn on the electric telescopic rod 501 to drive the driving frame 502 to move, realizing the movement of the discharge pipe 4 and the guide plate 504, and moving the guide plate 504 into the crack. During this process, through the connection of the driving rod 611 and the driving frame 502, the spray cylinder 609 is moved, and the spray cylinder 609 is moved into the crack; When the driving frame 502 moves, it is driven by the driving rack 506. Through the meshing connection of the driving rack 506 and the driving gear 507, the driving gear 507 is rotated, and then the first bevel gear connection mechanism 508 is rotated, thereby realizing the rotation of the driving gear 509. Through the meshing connection of the driving gear 509 and the first spur gear connection mechanism 510, the first spur gear connection mechanism 510 is rotated. Through the rotation of the first spur gear connection mechanism 510, the connecting rod 511 is rotated, so that the connecting rod 511 does not contact the guide plate 504; When the connecting rod 511 is not in contact with the guide plate 504, the spring telescopic column 503 stretches and pushes the guide plate 504 to move, so that the roller 505 contacts the crack end face. When the cart 1 moves, since the guide plate 504 is always in contact with both ends of the crack, and the discharge pipe 4 is between the two guide plates 504, when the cart 1 moves, due to the curvature of the crack, the position of the guide plate 504 also moves with the moving rod at this time. For this reason, the spring telescopic column 503 can be continuously stretched and compressed, enabling the discharge pipe 4 to always be at the top of the crack, facilitating the repair of the curved crack. The operator turns on the output pump 3 to discharge the repair agent inside the placement cylinder 2 into the crack for crack repair. A dual switch can be set for the output pump 3 to avoid the problem of waste of the repair agent caused by the operator accidentally touching the switch of the output pump 3, ensuring the safety of the operator when using the device; During the repair process, turn on the collecting fan 604 to adsorb the dust inside the crack, so that the dust enters the collecting box 602 for dust collection. During the dust suction process, the output shaft of the collecting fan 604 drives the stirring frame 606 to rotate through the second bevel gear connection mechanism 607 to stir the adhesive, avoiding the problem of the adhesive drying inside the fixed cylinder 605 and facilitating the discharge of the adhesive. During the stirring process, drive the connecting column 610 to rotate to make the spray cylinder 609 rotate, and evenly spray the adhesive on the crack end face to facilitate the subsequent repair of the crack; During the repair process, turn on the stirring motor 701 to drive the stirring blade 9 to rotate and stir the repair agent inside the placement cylinder 2. The stirring motor 701 drives the belt connection mechanism 702 to rotate, causing the mounting plate 703 to rotate. By rotating the mounting plate 703, the adjusting telescopic frame 704 and the adjusting telescopic rod 705 are driven to rotate, and finally the vibrating cylinder 707 rotates. During this process, through the connection of the second spur gear connection mechanism 708, the adjusting threaded cylinder 709 rotates. Limited by the limiting rod 711, the reciprocating lead screw 710 reciprocates inside the adjusting threaded cylinder 709, and then the moving rod 712 reciprocates. At this time, the moving disk 713 can be driven to reciprocate, thereby realizing the reciprocating movement of the vibrating cylinder 707, making the eccentrically mounted vibrating cylinder 707 vibrate inside the repair agent to discharge the bubbles inside the repair agent, making the strength high after the crack is patched and improving the repair effect of the crack; After the plugging is completed, turn off the output pump 3, the collecting fan 604 and the stirring motor 701. Then turn on the electric telescopic rod 501 to reset the driving frame 502, the guide plate 504 and the connecting rod 511. The connecting rod 511 will contact the guide plate 504, and the electric telescopic rod 501 can be compressed.
