A fixed plug rod 4 is slidably connected to the inner wall of the cavity of the fixed sleeve rod 2. A plurality of second limiting holes 5 are evenly opened on the top surface of the fixed plug rod 4. A mounting bolt 6 is threadedly penetrated on the top surface of the fixed plug rod 4. The same locking bolt 7 is arranged in the first limiting hole 3 and one of the opposite second limiting holes 5.

As further shown in Figures 1 and 3, it is worth specifically explaining that an installation box 8 is fixedly connected at the center of the top surface of the fixed base plate 1, and a rotating shaft 9 is rotatably connected to the top surface of the installation box 8. The rotating shaft 9 passes through the top surface of the installation box 8, and a screw column 10 is coaxially fixedly connected to the top of the rotating shaft 9. A driving bevel gear 11 is coaxially fixedly connected to the bottom end of the rotating shaft 9. Fixed plates 12 are fixedly connected to both sides of the top surface of the fixed base plate 1, and a bidirectional threaded rod 13 is rotatably connected between the two fixed plates 12. The bidirectional threaded rod 13 rotatably passes through the installation box 8, and a driven bevel gear 14 is fastened and sleeved on the outer surface of the bidirectional threaded rod 13, and the driving bevel gear 11 is meshingly connected with the driven bevel gear 14.

As further shown in Figures 1 and 3, it is worth specifically explaining that the outer surface of the bidirectional threaded rod 13 is threadedly connected to two parallel threaded sleeves 15, first through grooves 16 are provided on both sides of the top surface of the fixed base plate 1, and sliding grooves 17 are provided on the inner walls at both ends of the two first through grooves 16. A connecting block 18 is fixedly connected to the outer surface of the threaded sleeve 15, a sliding block 19 is fixedly connected to the bottom surface of the connecting block 18, the sliding groove 17 is adapted to the sliding block 19, and an anchor plate 20 is fixedly connected to the bottom surface of the sliding block 19.

As further shown in Figures 1 and 3, it is worth specifically explaining that an insert block 21 is fixedly connected at the center of the bottom surface of the fixed base plate 1, a second through groove 22 is opened on the insert block 21, a sliding column 23 is fixedly connected between the top surface and the bottom surface of the inner wall of the second through groove 22, a sliding sleeve 24 is slidingly sleeved on the outer surface of the sliding column 23, a connecting rod 25 is hinged between the outer surface of the sliding sleeve 24 and the two anchor plates 20, and a plurality of evenly distributed tips 26 are fixedly connected to the outer wall of the anchor plate 20 away from the connecting rod 25.

This solution has the following working process: when the staff is reinforcing the crack, they first insert the anchor plate 20 and the plug block 21 into the crack, loosen the locking bolt 7 to release the restriction on the fixed plug rod 4, adjust the fixed plug rod 4 to an appropriate length according to the size of the crack, fix the fixed plug rod 4 by installing the bolt 6, tighten the locking bolt 7 to lock and fix the fixed sleeve rod 2 and the fixed plug rod 4, and complete the installation of the reinforcement device.

Rotating the screw column 10 causes the active bevel gear 11 to rotate, and through the meshing action, the active bevel gear 11 drives the driven bevel gear 14 to rotate, thereby causing the bidirectional threaded rod 13 to rotate, and the two threaded sleeves 15 move relatively on the bidirectional threaded rod 13 at the same time, and drive the two anchor plates 20 to move relative to each other under the action of the slider 19. The two anchor plates 20 respectively contact the inner walls on both sides of the crack, and multiple tips 26 arranged on the outer wall of the anchor plate 20 are inserted into the inner wall of the crack to support and fix the crack. The two connecting rods 25 respectively support the anchor plates 20, further improving the reinforcement effect and having higher stability.

According to the above working process, it can be known that by setting the fixed sleeve rod 2 and the fixed insertion rod 4, the reinforcement device can be used for cracks of different sizes, and by setting the mounting bolts 6 and the locking bolts 7, the adjusted reinforcement device is fixed. The operation is simple and easy to use, and the problem that the reinforcement device is not easily applicable to cracks of different sizes is effectively avoided.

By adjusting the screw column 10, the active bevel gear 11 and the driven bevel gear 14 are matched, thereby driving the bidirectional threaded rod 13 to rotate.

By providing a connecting rod 25, the connecting rod 25 supports the two anchor plates 20, thereby improving the reinforcement effect and stability, and effectively avoiding the problem of a relatively simple reinforcement method with a poor reinforcement effect.

As further shown in Figures 1 and 3, it is worth explaining in detail that the fixed rods 4 are symmetrically distributed with the fixed base plate 1 as the center, ensuring that the device can be fixed on both sides of the crack, the locking bolt 7 is a handle bolt, which is convenient for the staff to better turn the locking bolt 7, and the installation box 8 is a bottomless square structure with a hollow interior, and two threaded sleeves 15 are respectively arranged on both sides of the installation box 8.

As further shown in Figure 1, it is worth explaining in detail that the two first through grooves 16 are respectively located on both sides of the installation box 8, the bottom width of the connecting block 18 is smaller than the width of the first through groove 16, and the width of the anchor plate 20 is smaller than the width of the first through groove 16, so that the slider 19 will not be interfered with by the connecting block 18 and the anchor plate 20 when sliding.

In summary: When the staff is reinforcing the cracks, they first insert the anchor plate 20 and the plug block 21 into the cracks, loosen the locking bolt 7 to release the restriction on the fixed plug rod 4, adjust the fixed plug rod 4 to an appropriate length according to the size of the crack, fix the fixed plug rod 4 by installing the bolt 6, tighten the locking bolt 7 to lock the fixed sleeve rod 2 and the fixed plug rod 4, and complete the installation of the reinforcement device. The operation is simple and easy to use, and effectively avoids the problem that the reinforcement device is not easy to adapt to cracks of different sizes.

Rotating the screw column 10 causes the active bevel gear 11 to rotate, and through the meshing action, the active bevel gear 11 drives the driven bevel gear 14 to rotate, thereby causing the bidirectional threaded rod 13 to rotate, and the two threaded sleeves 15 move relatively on the bidirectional threaded rod 13 at the same time, and drive the two anchor plates 20 to move relative to each other under the action of the slider 19. The two anchor plates 20 respectively contact the inner walls on both sides of the crack, and multiple tips 26 provided on the outer wall of the anchor plate 20 are inserted into the inner wall of the crack to support and fix the crack. The two connecting rods 25 respectively support the anchor plates 20, further improving the reinforcement effect, and having higher stability, effectively avoiding the problem of relatively simple reinforcement method and poor reinforcement effect.
