Description

Technical Field

[0001] This utility model relates to the field of drilling rig construction technology. More specifically, this utility model relates to a stabilization device for a drilling rig used in geological disaster engineering exploration. Background Technology

[0002] Engineering geological exploration is a technical work that provides basic geological data and disaster prevention basis for engineering construction. It involves conducting focused investigations and studies on the geological conditions of rocks, stratigraphic structures, minerals, groundwater, and landforms in a specific area. During the geological exploration process, drilling rigs are often used to drill underground to explore underground geology and mineral resources. Handheld drilling rigs are a commonly used type of shallow sampling drilling machinery for geological exploration. They have advantages such as small size, light weight, high efficiency, simple operation, and convenient relocation. However, it is difficult to ensure the stability of the drilling direction during drilling, and handheld drilling rigs are prone to fatigue after long-term operation. Therefore, it is necessary to set up guiding or stabilizing devices for drilling rigs to improve the accuracy and convenience of operation. However, the current design of stabilizing structures is generally a base plate plus support rods. For inclined or uneven geological conditions, this stabilizing structure cannot maintain stable support, and the uneven force in each direction during drilling affects construction and structural safety. Summary of the Invention

[0003] The purpose of this invention is to provide a stabilization device for geological disaster engineering exploration drilling rigs, in order to solve the technical problem of limited adaptability of the transition support for solar and rain sensors in the prior art.

[0004] To achieve these objectives and other advantages according to this utility model, a stabilization device for a geological disaster engineering exploration drilling rig is provided, comprising:

[0005] The support frame includes a base plate with a working hole through the center of the base plate. A guide cylinder is fixedly connected to the upper surface of the base plate around the working hole. The axial direction of the guide cylinder is perpendicular to the base plate. Screw holes are symmetrically opened on the outer side of the guide cylinder on the base plate.

[0006] The sliding frame is slidably connected to the upper inner side of the guide cylinder. The main body of the drilling rig is detachably connected to the sliding frame, and the drill rod passes through the sliding frame and is located on the central axis of the working hole. The sliding frame slides axially along the inner side of the guide cylinder to achieve movement perpendicular to the working hole.

[0007] The fixing component includes adjusting bolts and anchors corresponding to the number of screw holes.

The anchors are distributed on the outside of the adjusting bolts relative to the guide cylinder. The upper end of the anchor has a nail hole, and the lower end of the anchor is used to drive into the ground. After driving, the height of the nail hole is lower than the height of the upper end of the adjusting bolt. A limit rope is tightened between the nail hole and the adjusting bolt.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 , Figure 2 As shown, the geological disaster engineering exploration drilling rig stabilization device of this utility model includes:

[0021] The support frame 1 includes a base plate 3, a working hole 17 is provided through the middle of the base plate 3, a guide cylinder 4 is fixedly connected to the outer periphery of the working hole on the upper surface of the base plate 3, the axial direction of the guide cylinder 4 is perpendicular to the base plate 3, and screw holes are symmetrically provided on the outer side of the guide cylinder 4 on the base plate 3.

[0022] The sliding frame 2 is slidably connected to the upper inner side of the guide cylinder 4. The main body of the drilling rig 20 is detachably connected to the sliding frame 2, and the drill rod passes through the sliding frame 2 and is located on the central axis of the working hole. The sliding frame 2 slides axially along the inner side of the guide cylinder 4 to achieve movement perpendicular to the working hole.

[0023] The fixing component includes adjusting bolts 5 and anchors 6, which are respectively set in the number of screw holes. The adjusting bolts 5 are screwed into the screw holes. The bottom of the adjusting bolts 5 is provided with a buffer pad 7 for supporting the formation surface. The anchors 6 are distributed on the outside of the adjusting bolts 5 relative to the guide cylinder 4. The upper end of the anchor 6 has a nail hole 8. The lower end of the anchor 6 is used to drive into the formation. After driving, the height of the nail hole 8 is lower than the height of the upper end of the adjusting bolt 5. A limit rope 9 is tightened between the nail hole 8 and the adjusting bolt 5.

[0024] The support frame 1 serves as a stable support for the drilling rig and guides its movement path. It has a certain structural strength. The base plate 3 has a certain thickness to better guide and limit the adjusting bolts 5. The inner diameter of the guide cylinder 4, i.e., the inner space diameter, is larger than the outer diameter of the main structure of the drilling rig. The perforation state of the guide cylinder 4 can be designed as needed to facilitate sampling or soil removal, and water supply for cooling the drill bit. The drill rod passes through the sliding frame 2 and the working hole and then drills towards the bottom surface. The inner side of the sliding frame 2 is designed according to the shape and size of the main structure of the drilling rig. Corresponding inserts can also be designed, as long as they are fitted over the main body of the drilling rig and do not move relative to it.

[0025] In use, the sliding frame 2, matching the drilling rig structure, is fitted onto the lower surface of the main body of the drilling rig. Then, multiple anchor bolts 6 are driven into the ground on the outer side of the drilling location. The bolt holes 8 at the top of the anchor bolts 6 are located outside the ground. One end of the limiting rope 9 is inserted into the bolt hole 8, and a limiting bolt is screwed into the screw hole of the base plate 3. It is not screwed all the way in initially; the head of the limiting bolt is left with some space from the base plate 3 to facilitate winding and connecting the limiting rope 9. A nut can be screwed into the tail end of the limiting bolt, i.e., the lower end, after it protrudes from the base plate 3, to better fix the position of the limiting bolt. The position is adjusted according to the number of limiting bolts. When the surface of the stratum where the bolts are located is uneven, adjust the tightening depth of each limit bolt relative to the base plate 3 to better support the stratum surface and ensure the position of the base plate 3 is balanced and stable. After determining the position, tighten and fix the limit rope 9 (e.g., by changing the number of wrapping turns and tying a knot or setting a lock). At this time, the position of the support frame 1 is fixed. Then, place the sliding frame 2 in the guide frame, push the drilling machine along the guide frame, start the drilling machine, and drill a hole in the stratum surface. During drilling, the rock, soil and water flow are discharged from the space between the base plate 3 and the stratum surface after being supported by the adjustment bolts 5.

[0026] The geological disaster engineering exploration drilling rig stabilization device of this utility model includes a support frame 1, a sliding frame 2, and a fixing component. The support frame 1 includes a guide cylinder 4 and a base plate 3. The fixing component is connected to the base plate 3. The limiting bolt is adjusted according to the surface condition of the stratum to ensure that the base plate 3 is in a balanced and stable position. The bottom of the limiting bolt has a buffer pad 7 that supports the stratum surface and provides shock absorption protection for the support frame 1 and the sliding frame 2 during drilling operations. It is fixed to the stratum surface by an anchor 6. A limiting rope 9 is connected between the anchor 6 and the adjacent adjusting bolt 5. The limiting rope 9 is used to press down on the base plate 3 to improve the stability of the base plate 3. It can also be applied to strata with slopes. The drilling rig moves axially along the guide cylinder 4 through the sliding frame 2 to ensure that the drilling direction is stable and controllable.

[0027] In another technical solution, such as Figure 1-2As shown, the upper end of the guide cylinder 4 is provided with multiple guide grooves 10 along the length direction. The sliding frame 2 is an annular sleeve with an L-shaped cross-section. The main body of the drilling rig is nested in the upper inner side of the annular sleeve. A slider 11 is connected to the outer side of the annular sleeve. The slider 11 is correspondingly arranged with the guide groove 10 and located in the guide groove 10. The annular sleeve is slidably connected to the upper inner side of the guide cylinder 4 through the slider 11.

[0028] The L-shaped annular sleeve mainly serves to support and fix the main body of the drilling rig. It is designed according to the shape and size of the main body of the drilling rig, and corresponding inserts can also be designed. It is only necessary to ensure that it fits outside the main body of the drilling rig and does not move relative to it. The movement direction of the drilling rig is mainly guided by the sliding of the slider 11 in the guide groove 10.

[0029] In another technical solution, such as Figure 1-2 As shown, the outer diameter of the annular sleeve is slightly smaller than the inner diameter of the guide cylinder 4. An arc-shaped elastic pad 12 is also provided on the annular sleeve near the slider 11. The thickness of the elastic pad 12 is no greater than half the difference between the inner diameter of the guide cylinder 4 and the outer diameter of the annular sleeve.

[0030] When the annular sleeve shifts, the elastic pad 12 at the corresponding position is pressed against the inner wall of the guide cylinder 4 for buffering. The thickness of the elastic pad 12 can be close to half the difference between the inner diameter of the guide cylinder 4 and the outer diameter of the annular sleeve without affecting the sliding of the slider 11, thereby improving the buffering effect and avoiding excessive stress damage between the slider 11 and the annular sleeve when the guide shifts.

[0031] In another technical solution, such as Figure 1-2 As shown, a support hole 13 is provided on the base plate 3. The support hole 13 is located between the screw hole and the guide cylinder 4 and is close to the guide cylinder 4. A support block 14 is inserted into the support hole 13. The support block 14 has upper and lower sections. The upper surface of the lower section of the support block 14 is used to abut against the bottom surface of the corresponding position on the base plate 3. A support pad 15 is provided at the bottom of the lower section to support the surface of the stratum.

[0032] A support block 14 is inserted into the ground surface through the support hole 13, and then the support block 14 is rotated so that the top surface of the lower section of the support block 14 abuts against the bottom surface of the base plate 3, further providing support and buffering for the position of the base plate 3 near the middle, and enhancing the support stability of the overall structure.

[0033] In another technical solution, such as Figure 1-2As shown, the support hole 13 is an elongated hole, and the upper section of the support block 14 is a columnar structure with an outer diameter not greater than the width of the support hole 13. The length of the lower section of the support block 14 is not greater than the length of the support hole 13 but greater than the width of the support hole 13. Arc-shaped grooves can also be formed on the bottom surface of the base plate 3 on both sides of the support hole 13, and support pads 15 can be arranged on the top surface of the lower section of the support block 14. The lower section of the support block 14 abuts against the arc-shaped groove for limiting its position, and support pads 15 are provided at both the upper and lower ends of the lower section of the support block 14 to further improve the cushioning capacity.

[0034] In another technical solution, such as Figure 1-2 As shown, an insertion hole 16 is provided through the guide cylinder 4 to connect a water pipe for cooling the drill bit, so that water can be introduced to cool the drill bit in time, discharge rock powder, and lubricate the drill rod.

[0035] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the drawings shown and described herein.
