[0032] In some technical solutions of the present application, the hoisting mechanism comprises a plurality of lifting assemblies, which are arranged around the upper mounting frame 3. The lifting assembly comprises a mounting cylinder 11 arranged in the vertical direction in the upper mounting frame 3, a lifting column 8 is arranged in the mounting cylinder 11, a notch is formed in the outer side wall of the mounting cylinder 11, a rack is arranged on the outer side wall of the lifting column 8, and part of the rack is exposed in the notch. A U-shaped bracket 12 is arranged on the outer side wall of the mounting cylinder 11, and the notch is arranged in the U-shaped region of the bracket 12. A rotating disc 14 is rotatably arranged on the bracket 12, and a spiral adjusting member 13 is arranged on the side of the rotating disc 14 opposite to the bracket 12, and the bracket 12 is arranged in the adjusting member 13. The two ends of the adjusting member 13 extend outward after passing through any two tooth gaps on the rack. The side of the rotating disc 14 away from the bracket 12 is provided with a driving assembly for controlling the rotation of the rotating disc 14. The lifting column 8 is detachably connected with the protective cylinder 1. The lifting assembly can make the protective cylinder 1 placed between the upper mounting frame 3 and the lower mounting frame 2 together with the drill rod penetrate into the ground, support the hole wall, and facilitate the lowering of the protective cylinder 1 into the drill hole, thereby improving the construction efficiency. The number of lifting assemblies is at least six, and the six lifting assemblies move synchronously, forcing the protective cylinder 1 connected therewith to penetrate into the ground smoothly and uniformly. The cross section of the mounting cylinder 11 is rectangular, the cross section of the lifting column 8 is also rectangular, the outer diameter of the lifting column 8 is slightly smaller than the inner diameter of the mounting cylinder 11, which can avoid the shaking of the lifting column 8 in the mounting cylinder 11.

The working principle of the lifting assembly is as follows: when the rotating disc 14 rotates clockwise, the two ends of the adjusting member 13 extend outward after passing through any two tooth gaps on the rack, so that the two ends of the adjusting member 13 continuously and alternately reciprocate through any two tooth gaps on the rack to lift the lifting column 8 arranged in the mounting cylinder 11; then the protective cylinder 1 placed in the drill hole can be lifted out of the drill hole; when the rotating disc 14 rotates counterclockwise, the two ends of the adjusting member 13 extend outward after passing through any two tooth gaps on the rack, so that the two ends of the adjusting member 13 continuously and alternately reciprocate through any two tooth gaps on the rack to force the lifting column 8 arranged in the mounting cylinder 11 to move downward in the vertical direction; then the protective cylinder 1 placed outside the drill hole can be pressed into the drill hole, forcing the protective cylinder 1 to gradually lower into the drill hole with the excavation of the drill hole; and the lifting column 8 moves slowly in the one-tooth gap of the spiral adjusting member 13, which can ensure that the protective cylinder 1 penetrates into the ground together with the drill rod, protects the drill hole, and supports the hole wall in real time.

The telescopic rods 5 are also hydraulic rods, and the number of the hydraulic rods is 6. When the telescopic rods 5 are used to fix the casing 1, the force of the telescopic rods 5 in contact with the outer wall of the casing 1 is uniform. The electromagnets 6 can be in close contact with the steel casing 1, so that the casing 1 does not slide downward in the borehole when it is not connected with the lifting column 8, thereby affecting the drill bit and the supporting work of the borehole.

[0034] In some technical schemes of the present application, the driving assembly comprises a gear 15 arranged on the side of the rotating disc 14 away from the support 12, a rotating shaft 19 rotatably arranged on the gear 15, a supporting block 18 arranged on the rotating shaft 19, a pulling rod 17 rotatably arranged on the supporting block 18, a clamping block 20 arranged in the tooth gap of the gear 15, and a rotating rod 16 arranged on the rotating shaft 19. Through the above structure, the movement of the rotating disc 14 can be manually adjusted, and the rotation speed of the rotating disc 14 can be artificially slowed down. In special cases, the position of the casing 1 in the borehole is ensured, and then the speed of the lifting column 8 in the vertical direction for placing the casing 1 in the hole is controlled, thereby ensuring the safety of installing the casing 1 for supporting.

[0035] In some technical schemes of the present application, the driving assembly comprises a driving motor 10 arranged on the upper mounting frame 3, and the driving motor 10 is in transmission connection with the rotating disc 14. The driving motor 10 can be controlled by the PLC controller to move synchronously with the other six driving motors 10, so that the casing 1 can be quickly and efficiently placed into the borehole, thereby improving the work efficiency.
