Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. In which like parts are designated by like reference numerals. It should be noted that as used in the following description, the terms "front," "back," "left," "right," "upper," and "lower" refer to directions in the drawings, and the terms "bottom" and "top," "inner," and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Referring to fig. 1, the present invention provides a technical solution: a super deep well drilling machine base with strong stability comprises a first base 1 and a second base 2, wherein the first base 1 and the second base 2 are connected through a lifting rotating mechanism 3, so that the height of the first base 1 can be adjusted;

the lifting rotating mechanism 3 comprises a hydraulic rod 4, a hydraulic cylinder 5, a transverse plate 6, a rotating shaft 7 and a rotating motor 8, the hydraulic rod 4 is fixed at the output end of the hydraulic cylinder 5, the hydraulic cylinder 5 is fixed on the transverse plate 6, the bottom of the transverse plate 6 is connected to the output end of the rotating motor 8 through the rotating shaft 7, and the rotating motor 8 is fixed on the second base 2;

a plurality of supporting rods 9 are fixed at the bottom of the first base 1, sleeves 10 corresponding to the supporting rods 9 are fixed on the second base 2, a plurality of jacks 11 are fixed on the second base 2, and fixing plates 12 used for fixedly connecting the first base 1 are arranged at the tops of the jacks 11.

A plurality of fixing rods 13 are arranged on the hydraulic rod 4, and the fixing rods 13 are fixedly connected through reinforcing rods 14, so that the supporting stability of the hydraulic rod 4 is higher.

The support rod 9 is connected with the sleeve 10 through threads, so that the stability of the first base 1 and the second base 2 is higher.

Be equipped with on the second base 2 and be used for strengthening stable seat 15, be equipped with on the stable seat 15 and be used for screw 16, be convenient for bore ground through the screw and make it more stable.
