The upper end surface of the upper placing plate 560 is movably mounted with a clamping plate. The telescopic rod 581 corresponds to the plate 580 one-to-one. The upper end surface of the telescopic rod 581 is fixedly provided with a baffle 582. A spring 583 is provided between the baffle 582 and the placement plate 560.

As shown in Figure 4, the locking group 59 includes a through slot 590. A rectangular through slot 590 is provided on the swing plate 2.

The opposite sections of the two threaded shafts 594 are threaded with locking nuts 595, and the locking nuts 595 are corresponding to The opposite surfaces of the swing plate 2 and 4 are rough surfaces.

When working, first manually move the base plate 1 and the grouting mechanism 5 and auxiliary mechanism 6 on it to the designated position through the rolling of the moving roller 10. At the same time, the base plate 1 is fixed at the designated position through the auxiliary mechanism 6, and this At this time, the compression plate 3 faces the gap area where drilling and grouting are required, and the left end surface of the compression plate 3 initially fits the gap area.

Then the telescopic guide rod 574 works so that its telescopic end extends, and its telescopic end drives the compression rod 573 to move to the left through the U-shaped frame 572, so the compression rod 573 exerts a force on the swing plate 24 to rotate downward. Therefore, the two swing plates 24 at the front and rear drive the compression plate 3 to compress the gap area of the wall, and the provided backing plate 550 deforms during the compression process of the compression plate 3, thereby reducing the distance between the compression plate 3 and the wall. The gap between them can reduce the overflow of cement slurry during the subsequent grouting process and ensure the subsequent grouting effect.

When the swing plate 24 drives the compression plate 3 to compress, the connecting plate 591 moves in the through slot 590, and the positioning block moves in the corresponding moving block groove. When the compression plate 3 has compacted the wall, , the locking nut 595 is fixed to the corresponding threaded shaft 594 through the threaded cooperation between the locking nut 595 and the corresponding threaded shaft 594, because the opposite surfaces between the locking nut 595 and the corresponding swing plate 24 are all The rough surface increases the friction between the locking nut 595 and the swing plate 24, that is, the positioning block and the swing plate 24 are relatively fixed. At this time, the swing plate 12, the corresponding swing plate 24, and the corresponding swing plate 24 The connecting plate one 591 and the corresponding connecting plate two 592 together form a stable triangular structure, so the positioning of the pressing plate 3 after being pressed is fixed while ensuring that the relationship between the swing plate one 2, the swing plate two 4 and the pressing plate 3 is ensured. The stability between the two ensures the compression effect of the compression plate 3 on the wall, and the compression group 57 drives the compression plate 3 through the swing plate 2 and the swing plate 2 4 to compress the compression plate 3. It can adapt to the compression operation of different inclined walls, which improves the applicability of the device.

During the process of the compression plate 3 compressing the wall, the two fitting plates 562 on the upper and lower sides of the compression plate 3 maintain preliminary fit with the wall through the provided springs 564, and then the external motor drives the drill. While the hole shaft 53 rotates, the hydraulic cylinder 52 works so that its telescopic end drives the sliding plate 51 to move to the left. Therefore, the sliding plate 51 drives the drilling shaft 53 on it and the corresponding drilling grouting assembly 54 to feed to the left synchronously, so the drilling The hole grouting assembly 54 drills holes in the wall, and during the drilling process, that is, when the sliding plate 51 moves to the left, the sliding plate 51 drives the push plate 565 on it to push the corresponding spring mounting plate 563 to move to the left. The spring mounting plate 563 moves to the left so that the corresponding spring 564 is compressed. Therefore, the elastic force generated by the compression of the spring 564 makes the corresponding fitting plate 562 closely adhere to the wall. At the same time, the rubber pad is deformed in the process, thereby Reduce the gap between the fit and the wall to avoid the problem of cement slurry overflowing during subsequent grouting.

In the initial state, the clamping plate 580 is located on the right side of the corresponding baffle 582. When the spring mounting plate 563 moves to the left, the U-shaped plate 584 drives the lower pressing column 585 and the two lower pressing blocks 586 to move synchronously. The lower pressure block 586 on the left side of the pressure column 585 first contacts the baffle 582, and during the movement of the lower pressure block 586, the corresponding lower pressure column 585, and the other lower pressure block 586, the baffle 582 is pressed so that the baffle 582 is moved. The plate 582 moves down, so the baffle 582 fails to prevent the clamping plate 580 from moving left during this process. The pushing plate 565 pushes the spring mounting plate 563 to drive the clamping plate 580 on it to move left. The lower pressing block 586 and the lower pressing column 585 do not move. When in contact with the baffle 582, the baffle 582 quickly resets and moves upward under the elastic force generated by the compression of the second spring 583, so the baffle 582 can block the corresponding clamping plate 580.

Then the hydraulic cylinder 52 works to extend its telescopic end, so its telescopic end drives the sliding plate 51 to move to the right, so the sliding plate 51 drives the drilling shaft 53 and the drilling grouting assembly 54 to move to the right. In this process, the external cylinder works The external cement slurry is injected into the gap through the drilling grouting assembly 54, and because the baffle 582 blocks the corresponding clamping plate 580 at this time, the fitting plate 562 always remains tight with the wall under the deformation caused by the compression of the spring 564. to avoid the problem of cement slurry overflowing due to the failure of the fitting plate 562 to adhere closely to the wall. After the cement slurry is initially solidified, the sliding plate 51 continues to move to the right. When the sliding plate 51 moves to the right, when the sliding plate 51 passes After the U-shaped plate 584 drives the corresponding lower pressure block 586 and the lower pressure column 585 to move a certain distance to the right, the lower pressure block 586 and the lower pressure column 585 contact the corresponding baffle 582 and press it down. Therefore, at this time, the baffle 582 is corresponding to the The clamping plate 580 has no limiting function, so the clamping plate 580 and the spring mounting plate 563 are quickly reset under the elastic force generated by the compression deformation of the corresponding spring 564.

The provided synchronization rod 567 makes the upper and lower spring mounting plates 563 move synchronously through the corresponding traverse blocks, so that both the upper and lower laminating plates 562 can perform laminating operations, and the circular structure and baffle of the lower pressing block 586 are provided. The arcuate surfaces of 582 cooperate with each other to facilitate the pressing block 586 or the pressing column 585 to cooperate with the baffle 582 during the movement, that is, to facilitate the pressing of the baffle 582.

When the drilling grouting assembly 54 is working, the sliding plate 51 moves to the left to drive the drilling to the left. At the same time, the drill bit is driven by an external motor to drill the wall. After the drilling is completed, the drill bit moves to the right, and the external high-pressure pump pumps the cement into the wall. It is pumped in through the inlet on the rotary jet diverter and pumped out into the gap through the outlet on the drill bit.

During operation, the base plate 1 is manually moved and pushed and the base plate 1 and the grouting mechanism 5 and auxiliary mechanism 6 on it are moved to the designated position through the rolling of the moving roller 10. Then the telescopic guide rod 2 62 is operated to retract its telescopic end. Therefore, its telescopic end drives the lifting plate 61 and the lifting column 60 to move downward. The lifting column 60 drives the pressing plate 63 to move downward and contact the ground in the mine. Then the premise is pressed by the grouting mechanism 5 and the auxiliary mechanism 6. In this process The provided retaining bars 66 block the inclined plate 65, so the inclined plate 65 is always in a state of being inclined downward in the direction from left to right. The plurality of inclined plates 65 are in contact with the ground so that the pressure plate 63 is in contact with the ground.
