Two groups of positioning bolts 10 are inserted from top to bottom at the top of the positioning angle steel 9, and two groups of positioning screw eyes 11 are respectively arranged at the front and rear ends of the right side of the top of the slewing platform frame 3;

[0031] The shape and size of the interior of the storage groove 4 match the shape and size of the exterior of the first hydraulic cylinder 5, the connecting bolt rod 6, the connecting rod 7, and the docking bolt rod 8. The docking bolt rod 8 is movably connected to the hydraulic column bearing seat 12. The bottom end of the positioning angle steel 9 is flush with the bottom end of the hydraulic column bearing seat 12. The positioning bolt 10 penetrates the positioning angle steel 9 and extends into the interior of the positioning screw eye 11. The top of the hydraulic column bearing seat 12 is fixedly connected to the bottom end of the second hydraulic cylinder 13.

[0032] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the positioning bolts 10 on the positioning angle steel 9 are manually removed. As the positioning bolts 10 are pulled out from the positioning screw eyes 11, the hydraulic column bearing seat 12 together with the second hydraulic cylinder 13, the rotary reducer 14 and other components above can be turned over. The traction assembly formed by the first hydraulic cylinder 5, the connecting bolt rod 6, the connecting pull rod 7, and the docking bolt rod 8 pulls the hydraulic column bearing seat 12. The rotary reducer 14 drives the guide rail 15 to rotate and tilt its angle. At the same time, the rotator 16 is moved to the lower end of the guide rail 15 to reduce the overall height of the equipment. The first hydraulic cylinder 5 can adjust the turning range of the hydraulic column bearing seat 12.

[0033] Embodiment 2: The left sides of the front and rear ends of the crawler chassis assembly 1 are respectively fixedly connected with hydraulic cylinder fixed covers 17, and a third hydraulic cylinder 18 is arranged inside the hydraulic cylinder fixed cover 17. The output end of the third hydraulic cylinder 18 is equipped with a load-bearing wheel 19. When the third hydraulic cylinder 18 is retracted, the bottom end of the load-bearing wheel 19 is higher than the bottom end of the crawler chassis assembly 1.

A plurality of groups of reserved grooves 22 are arranged inside the steel cover plate 21. A plurality of groups of pressure sensors 24 are installed at the bottom of the fixed steel shell 20. A steel contact 23 is fixedly connected to the top of the pressure sensor 24. The outer diameter of the steel contact 23 matches the inner diameter of the reserved groove 22. The top of the steel contact 23 is higher than the top of the steel cover plate 21, and the lifting height can be adjusted according to pressure feedback.

[0036] Specifically, Figure 1 and Figure 6 As shown, the steel contact 23 in the fixed steel shell 20 contacts the top wall, the pressure sensor 24 is stressed and feeds back the top contact pressure to the control assembly 2, and the reserved groove 22 in the steel cover plate 21 reserves space for the up and down displacement of the steel contact 23. The control assembly 2 can timely adjust the lifting height of the second hydraulic cylinder 13 according to the pressure value fed back by the pressure sensor 24.

[0037] Working principle: When the present invention is in use, first, the crawler chassis assembly 1 serves as the driving assembly of the drilling rig, which can drive the drilling rig to move underground. According to the height of the underground mine tunnel, when it is necessary to flip and lower the overall height of the drilling rig, first manually remove the positioning bolts 10 on the positioning angle steel 9. As the positioning bolts 10 are pulled out of the positioning screw eyes 11, the hydraulic column bearing seat 12 together with the second hydraulic cylinder 13, the rotary reducer 14 and other components above can be flipped together. The traction assembly formed by the first hydraulic cylinder 5, the connecting bolt rod 6, the connecting pull rod 7, and the docking bolt rod 8 pulls the hydraulic column bearing seat 12. The rotary reducer 14 drives the guide rail 15 to rotate and tilt its angle. At the same time, the rotator 16 is moved to the lower end of the guide rail 15 to reduce the overall height of the equipment. The first hydraulic cylinder 5 can adjust the flipping amplitude of the hydraulic column bearing seat 12. As the hydraulic column bearing seat 12 flips backward, the third hydraulic cylinder 18 in the hydraulic cylinder fixed cover 17 extends downward, pushing the load-bearing wheel 19 downward against the ground, so that the equipment is not easy to tilt when walking, and can also provide bottom support for the second hydraulic cylinder 13 when lifting. When drilling underground, the second hydraulic cylinder 13 extends upward to support the top of the well, and the steel contact 23 in the fixed steel shell 20 contacts the top wall. The pressure sensor 24 is stressed and feeds back the pressure of the top contact to the control assembly 2. The reserved groove 22 in the steel cover plate 21 reserves space for the up and down displacement of the steel contact 23. The control assembly 2 can adjust the lifting height of the second hydraulic cylinder 13 in time according to the pressure value fed back by the pressure sensor 24.
