Description

Technical Field

[0001] The utility model relates to the technical field of coal mine drilling rigs, in particular to a coal mine drilling rig stabilizing device. Background Art

[0002] In coal mining operations, drilling rigs are core equipment for key processes such as coal seam drilling, gas extraction, and roadway support. Due to the complex underground environment of coal mines, characterized by variable geological structures, limited working space, and frequent vibrations, the stability of the drilling rig during operation directly affects drilling accuracy, equipment lifespan, and operational safety. Therefore, the reliability of the drilling rig's stabilization device is crucial.

[0003] At present, the existing technology of coal mine drilling rig stabilization device mainly realizes the limit in the following two ways after adjusting the drilling angle of the drilling rig:

[0004] Friction limiter: Bolts rest against a fixed plate, using friction to limit the rotation of the drill assembly. This method offers the advantage of allowing the drilling angle to be adjusted arbitrarily. However, its disadvantage is that the friction generated by the bolts is easily attenuated by vibration, causing the drill to loosen during operation, resulting in unstable limiter effects and potentially leading to safety hazards such as drill offset and equipment damage.

[0005] Positioning hole insertion limit method: Fixation is achieved by inserting bolts directly into pre-set positioning holes. This method provides good positioning stability, but because the positioning holes are fixed in position, the drill can only operate at a preset angle and cannot be adjusted to any angle according to actual operation requirements. It has poor flexibility and adaptability, and cannot meet the drilling needs of complex geological conditions.

[0006] In summary, existing coal mine drill stabilization devices face a technical bottleneck: the difficulty in balancing angle adjustment flexibility with position limiting stability. Designing a stabilization device that allows for arbitrary drill angle adjustment while ensuring reliable position limiting has become a pressing technical challenge in this field.

[0039] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention. Example

[0040] like Figure 1-5 As shown, a coal mine drilling rig stabilizing device includes:

[0041] Support base 1;

[0042] A pair of guide assemblies 2 are provided, and the pair of guide assemblies 2 are vertically fixed on the support base 1, and include:

[0043] The vertical rod 21 is fixed vertically on the support base 1;

[0044] A fixed shaft 22 is fixed vertically to the middle of the vertical pole 21, and the fixed shaft 22 faces the other vertical pole 21;

[0045] The positioning ring 24 is coaxially fixed to the outer side of the fixed shaft 22 through the connecting rod 23;

[0046] The positioning hole 241 is annularly formed on the positioning ring 24;

[0047] The annular track 29 is coaxially arranged on the outside of the positioning ring 24 and has a gap between it and the positioning ring 24;

[0048] An inner ring 26 is fixed to the outer side of the positioning ring 24 via a second connecting rod 25, and an outer ring 28 is fixed to the vertical rod 21 via a third connecting rod 27. The annular track 29 is formed by the gap between the inner ring 26 and the outer ring 28. The inner ring 26, the outer ring 28 and the central axis of the fixed shaft 22 coincide.

[0049] The drilling assembly 3 is rotatably connected between the two guide assemblies 2 and includes:

[0050] Rotating support 31;

[0051] The fixing ring 32 is fixed to the two side surfaces of the rotating support 31 and is rotatably sleeved on the outer side of the fixed shaft 22;

[0052] The drilling rig body 33 is slidably connected to the rotating support 31 in the longitudinal direction via a screw rod;

[0053] The fixed column 34 is located in the annular track 29 and rotates along the annular track 29;

[0054] telescopic member, which rotates vertically on the free end of the fixed column 34;

[0055] A positioning bolt 38 is threadedly connected to the telescopic end of the telescopic member, and one end is inserted into the positioning hole 241;

[0056] The telescopic member specifically includes a fixing block 35 rotatably connected to the free end of the fixing column 34. The fixing block 35 has an internal thread extending through an adjusting bolt 36. One end of the adjusting bolt 36 is rotatably connected to a bearing block 37 via a bearing. The positioning bolt 38 is threaded through the bearing block 37.

[0057] The telescopic member can also be an electric telescopic rod, which has a fixed end and a telescopic end. The fixed end of the electric telescopic end is rotatably connected to the free end of the fixed column 34, and the telescopic end of the electric telescopic end is rotatably connected to the bearing block 37 through a bearing, and the positioning bolt 38 is threaded through the bearing block 37.

[0058] in:

[0059] Rotate the drilling assembly 3 to a certain angle, adjust the length of the telescopic member until the positioning bolt 38 is aligned with the positioning hole 241 on the positioning ring 24 that is closest to the positioning bolt 38, and insert the positioning bolt 38 into the corresponding positioning hole 241 to limit the drilling assembly 3.

[0060] The existing problem is that after the drilling angle of the drill body 33 is adjusted, there are generally two ways to limit the drill body 33. The first is to use a bolt to press against a certain plate and use friction to limit the drill assembly 3. The advantage of this method is that the drilling angle of the drill body 33 can be arbitrarily adjusted, but the disadvantage is that it is easy to loosen and the limiting effect is poor. The second method is to use a bolt inserted into a positioning hole to limit the drill assembly 3. The advantage of this method is that the limiting position is relatively stable, but the disadvantage is that the drilling angle of the drill body 33 cannot be arbitrarily adjusted.

[0061] The utility model uses a combination of the telescopic member, the positioning bolt 38 and the positioning hole 241. After the angle of the drill body 33 is adjusted, the position of the positioning bolt 38 can be adjusted by the telescopic member first, and the length of the telescopic member is adjusted until the positioning bolt 38 is aligned with the positioning hole 241 on the positioning ring 24 that is closest to the positioning bolt 38. The positioning bolt 38 is inserted into the corresponding positioning hole 241 to form a limit for the drill assembly 3. The utility model can not only adjust the angle of the drill body 33 at will, but also has a good limiting effect.

[0062] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
