Description

Technical Field

[0001] The utility model relates to the technical field of geological drilling auxiliary equipment, in particular to a geological drilling stabilizer. Background Art

[0002] Geological drilling refers to a geological project that uses certain drilling machinery and technology to obtain rock and mineral cores below the surface to make reliable evaluations of geological and mineral resource parameters. Drilling is an important technical means in geological exploration. A drill rig drills downward from the surface to form a cylindrical borehole in the stratum to identify and divide the stratum. Cores, ore samples, and soil samples can be obtained from different depths in the borehole for analysis and research to determine the physical and mechanical properties and indicators of rocks and soil layers to provide design needs.

[0003] When the drill rod goes deep into the borehole for geological drilling, the drill rod is in contact with the borehole mouth and rubs for a long time, which can easily cause a large amount of soil blocks in the borehole to fall off as the drilling time increases, causing the diameter of the borehole to expand. As a result, the shaking range of the drill rod in the borehole continues to increase during drilling, which has an adverse effect on the drilling stability of the drill rod. Utility Model Content

[0009] As a preferred solution of a geological drilling stabilizer described in the utility model, a card slot is opened on the side of the positioning plate corresponding to the stabilizing frame, and a card block corresponding to the card slot is fixedly connected to one end of the extension plate close to the positioning plate. The extension plate and the card slot are arranged to be engaged with each other. When the positioning plate is not in use, the extension plate can be put into the stabilizing frame and engaged with the card slot, which is convenient for storing the device and reduces the occupied space.

[0010] As a preferred solution of a geological drilling stabilizer described in the utility model, a cone head is fixedly connected to the bottom of the casing, and the cone head is made of wear-resistant stainless steel.

[0012] As a preferred solution of a geological drilling stabilizer described in the utility model, the inner embedded ring is higher than the outer embedded ring, and the outer side walls of the inner embedded ring and the outer embedded ring are both provided with external thread patterns. During installation, the positioning plate needs to be rotated so that the threads of the inner embedded ring and the outer embedded ring are screwed into the ground below, thereby improving the positioning stability of the positioning plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model realizes mutual cooperation among the positioning plate, the stabilizing frame and the casing, and by arranging a positioning plate at the geological borehole, when the drill rod penetrates into the borehole, the soil is directly contacted with the drill rod instead of directly contacting the drill rod, thereby protecting the borehole mouth, preventing the soil blocks at the borehole from falling off in large quantities as the drilling time increases, causing the diameter of the borehole to expand, thereby ensuring that the drilling shaking of the drill rod is within a certain controllable range, and improving the drilling stability of the drill rod.

[0027] At the same time, a card slot 7 is opened at the side of the positioning disk 1 corresponding to the stabilizing frame 4, and a card block corresponding to the card slot 7 is fixedly connected to the end of the extension plate 5 close to the positioning disk 1. The extension plate 5 and the card slot 7 are engaged with each other. When the positioning disk 1 is not in use, the extension plate 5 can be put into the stabilizing frame 4 and engaged with the card slot 7, which is convenient for storing the device and reduces the occupied space.

[0028] A positioning hole 8 is provided at the top of the stabilizing frame 4 and inside the extension plate 5, an anchor rod 9 is threadedly connected to the inside of the positioning hole 8, a casing 10 is fixedly connected to the bottom of the positioning plate 1, and a cone head 13 is fixedly connected to the bottom of the casing 10.
