Description

Technical Field

[0001] The present invention relates to the technical field of geological exploration, and more specifically, to a hole expanding device for geological exploration. Background Art

[0002] Geological exploration is a survey and research activity that uses various methods to investigate and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters. During geological exploration and research activities, it is necessary to open a survey hole in the soil to facilitate soil investigation and survey. Due to the variety of survey equipment, when the survey equipment is larger than the diameter of the survey hole, the survey hole needs to be expanded to allow the survey equipment to survey.

[0003] The existing reaming device used in geological exploration is: a rotating reaming drill bit is extended into the exploration hole, the reaming drill bit squeezes and breaks the soil on the side wall of the exploration hole, and then transports the soil to the ground through the gap between the reaming drill bit and the side wall of the exploration hole; however, since the diameter of the reaming drill bit is fixed and cannot be adjusted, it may be necessary to replace the reaming drill bit multiple times and perform multiple reaming operations, which is relatively troublesome, and the selection of geological exploration equipment and the determination of the aperture size of the geological exploration hole need to comprehensively consider multiple factors. In actual work, surveyors need to select appropriate exploration equipment and aperture size according to the actual situation they face to achieve the best exploration effect. When the aperture size of the geological exploration hole is required to be too large, the original rotating device driving the overly large reaming drill bit will cause a large load on the rotating device, making it difficult to reame the geology and inconvenient to reame. In view of this, we propose a reaming device for geological exploration. Summary of the invention

[0015] A method for using a hole expanding device for geological exploration comprises the following steps:

[0016] S1. Expansion of small geological exploration holes;

[0017] S1.1 Pre-drilling of small geological exploration holes:

[0018] The output end of the motor is controlled to rotate in reverse through an external control mechanism, and the rotation of the input shaft drives the forward disk B and the output shaft to rotate. The reverse rotation of the forward disk B drives the reverse disk to rotate in reverse through the limit column B, so that the reaming assembly and the adjustment assembly rotate in reverse at the same time. The mounting seat A is controlled to descend through one of the lifting mechanisms, so that the reaming assembly drills the land, and the soil is discharged from the discharge channel. After the drilling is completed, the mounting seat A is controlled to rise through the lifting mechanism, so that the reaming assembly is separated from the drilled hole;

[0019] S1.2, Adjustment and expansion of small geological exploration holes;

[0020] The motor output end is controlled to rotate in the forward direction through an external control mechanism. The reverse disk cannot rotate forward relative to the limit arc groove A, and the fixed hole expansion assembly rotates by itself, causing the top of the slide bar to drive the rotating rod and the ball block to move along the guide groove. The slide bar slides along the eccentric direction of the centripetal slide groove, the drill slides along the eccentric direction of the inclined groove, the cross block slides along the cross groove A, and the folding stopper is pulled up to block the cross groove A to prevent soil from entering the cross groove A during hole expansion. When the drill is adjusted to the appropriate position, the motor output end is controlled to stop, and the operation is the same as S1.1 to expand the hole drilled in step S1.1.

[0021] S1.3, resetting of the expansion assembly;

[0022] As with S1.2, the motor output end is controlled to rotate in the forward direction through an external control mechanism, so that the ball block moves along the guide groove to the centripetal end of another guide groove, causing the slide bar to slide along the centripetal slide groove in the centripetal direction until the drill returns to its original position;

[0023] S2. Expansion of large geological exploration holes;

[0024] S2.1, marking of pre-drilled holes and cracked holes;

[0025] According to the diameter of the large geological exploration hole, several pre-drilled hole marks are arranged on the ground in a circular structure with equal spacing, and at least one collapse hole mark is arranged according to the on-site conditions.

[0026] S2.2. Drill the free surface according to the pre-drilling mark;

[0027] The same operation as S1.1 is performed, and several pre-drilled holes of the same depth are drilled one by one according to the marked positions of the pre-drilled holes;

[0028] S2.3. Drill the crack hole according to the crack hole mark;

[0029] First, the operation is the same as S1.1. Several pre-drilled holes of the same depth are drilled according to the marked positions of the cracked holes. Then, the output end of the motor is directly controlled to rotate in the forward direction through the external control mechanism, so that the ball block moves to the eccentric end of the guide groove, and the drill slides along the eccentric direction of the inclined groove and inserts into the soil. Then, the motor is controlled to rotate in the reverse direction through the external control mechanism to drill auxiliary holes at the bottom of the pre-drilled holes of the cracked holes. After the auxiliary holes are drilled, cracked holes are formed. After the drill is adjusted and reset in the same way as S1.1, the mounting seat A is controlled to rise through the lifting mechanism, so that the hole expansion assembly is separated from the drilled hole. If there are multiple cracked hole marks, all the cracked holes are drilled in the same way as the above steps.

[0030] S2.3. Collapse and expansion of large geological exploration holes;

[0031] By controlling the moving mechanism, the rotating mechanism and the lifting mechanism, the bottom end of the cracking mechanism is inserted into the cracking hole until the bottom end of the cracking mechanism contacts the bottom end of the cracking hole, and the hydraulic cylinder is controlled by the external control mechanism, so that the movable end of the hydraulic cylinder drives the connecting shaft to move, so that the movable column moves in the casing, so that the connecting rod drives the cracking arc plate to slide along the limiting slide groove along the limiting strip, and the upper part of the cracking hole is cracked. The auxiliary hole makes it difficult to form a large depression during cracking, and makes cracking easier;

[0032] S2.4. Complete the cleaning of the collapsed soil manually. If there are multiple collapsed holes, collapse them one by one according to the above steps to form a large geological exploration hole prototype. The surface of the artificial geological exploration hole prototype is repaired.

[0033] The beneficial effects of the present invention are:

[0034] 1. The present invention adopts the structural design of the lifting mechanism, so that when the motor output end rotates in the reverse direction, the reaming assembly and the adjustment assembly rotate in the reverse direction at the same time, and the mounting seat A is controlled to descend by one of the lifting mechanisms, so that the reaming assembly drills the ground. When the motor output end rotates in the forward direction, the reverse disk cannot rotate in the forward direction relative to the limiting arc groove A, and the fixed reaming assembly rotates by itself, so that the drill cutter slides along the eccentric direction of the inclined groove, and the reaming size of the fixed reaming assembly is adjusted, so that when reaming a geological exploration hole, there is no need to replace the reaming drill bit, and reaming is convenient, which solves the technical problem of inconvenient reaming of the reaming device for geological exploration.

[0035] 2. The present invention adopts the structural design of the transverse groove A, the transverse block and the folding stopper, so that when the drill moves eccentrically, the transverse groove B still provides support for the transverse groove A, thereby improving the support strength of the drill during hole expansion, which is convenient for drilling relatively hard geology, and the folding stopper is pulled up to prevent soil from entering the transverse groove A, so as to improve the smoothness of the centripetal movement of the drill, reduce soil cleaning, and reduce the workload of workers, thereby further solving the technical problem of inconvenient hole expansion of the hole expansion device used for geological exploration.

[0036] 3. The present invention also designs a fracturing mechanism structure and a method for expanding a large geological exploration hole, so that when the diameter of the drilled geological exploration hole is required to be too large, there is no need to replace the drilling equipment, further solving the technical problem of the inconvenience of expanding the hole with an expanding device for geological exploration.

[0058] like Figures 1 to 12 As shown, the present invention relates to a hole-exploring device for geological exploration, comprising a moving mechanism 1, a rotating mechanism 2 is fixedly arranged on the top of the moving mechanism 1, a mounting platform 3 is fixedly arranged on the top of the rotating mechanism 2, lifting mechanisms 4 are fixedly arranged on both sides of the mounting platform 3 in a symmetrical structure, a mounting seat A5 and a mounting seat B6 are fixedly arranged on the movable ends of the two lifting mechanisms 4, both the mounting seat A5 and the mounting seat B6 are in an L-shaped structure, a hole-expanding mechanism 7 is arranged on the mounting seat A5, and a cracking mechanism 8 is arranged on the mounting seat B6;

[0059] The reaming mechanism 7 includes a motor 71, a reverse rotating component 72 and a reaming component 74. The motor 71 is fixedly provided with a top end of a mounting seat A5. The reverse rotating component 72 is arranged at a bottom end of the mounting seat A5. The rotating end of the reverse rotating component 72 is arranged with a forward rotating component 73. The input end passes through the mounting seat A5 and is fixedly connected to the output end of the motor 71. The reaming component 74 is fixedly provided at the output end of the forward rotating component 73. An adjusting component 75 is rotatably provided at the top end of the reaming component 74. The top end of the adjusting component 75 is fixedly connected to the rotating end of the reverse rotating component 72. The top end of the adjusting component 75 is fixedly connected to the rotating end of the reverse rotating component 72.

[0060] In an embodiment of the present invention, the reverse rotation component 72 includes a mounting disc 721, which is fixed at the bottom end of the mounting seat A5. A limiting ring groove A722 is provided on the mounting disc 721, and a reverse disc 723 is rotatably connected to the limiting ring groove A722. A plurality of limiting arc grooves A724 are provided on the reverse disc 723 in a ring-shaped and evenly spaced structure relative to the limiting ring groove A722. The gap between the limiting arc grooves A724 and the limiting ring groove A722 constitutes a limiting cavity A. A limiting column A725 is movably provided on the limiting cavity A, and the limiting column A725 is adapted to the limiting cavity A. The groove depth of the limiting arc groove A724 in the centripetal direction is a structure that gradually becomes shallower in the reverse direction. The limiting column A725 is elastically connected to the narrow part of the limiting arc groove A724 through a tension spring A726, and a limiting ring groove B727 is provided on the reverse disc 723. Through the above arrangement, the present invention ensures that under the elastic force of the tension spring A726, the limit column A725 is always in the middle of the limit cavity A, so that when the reverse disk 723 rotates in the reverse direction, a force is applied to the limit column A725 to move along the wide part of the limit cavity A, which does not affect the reverse rotation of the reverse disk 723. When the reverse disk 723 has a forward moving force, a force is applied to the limit column A725 to move along the narrow part of the limit cavity A, causing the reverse disk 723 to form a locking structure with the mounting disk 721 through the limit column A725, so that the reverse disk 723 cannot rotate in the forward direction.

[0061] In an embodiment of the present invention, the forward rotating component 73 includes a forward disk B731, which is rotatably arranged on the limiting ring groove B727.

The limiting column B733 is adapted to the limiting cavity B. The groove depth of the limiting arc groove B732 in the centripetal direction is a structure that gradually becomes shallower in the forward direction. The limiting column B733 is elastically connected to the narrow part of the limiting arc groove B732 through a tension spring B734. An input shaft 735 is fixedly arranged at the top of the forward disk B731. The top of the input shaft 735 passes through the mounting seat A5 and is fixedly connected to the output end of the motor 71. An output shaft 736 is fixedly arranged at the bottom of the forward disk B731. Through the above arrangement, the present invention can know that according to the principle of the reverse rotating component 72, when the output end of the motor 71 rotates forward, the forward disk B731 rotates forward. Since the reverse disk 723 cannot rotate forward, the forward disk B731 and the output shaft 736 rotate by themselves. When the output end of the motor 71 rotates forward, the forward disk B731 forms a locking structure with the reverse disk 723 through the limit column B733, and the reverse disk 723 and the output shaft 736 both rotate in the reverse direction.

[0074] S1.3, resetting the hole expansion assembly 74;

[0075] As in S1.2, the output end of the motor 71 is controlled to rotate in the forward direction by an external control mechanism, so that the ball block 754 moves along the guide groove 753 to the centripetal end of another guide groove 753, causing the slide bar 746 to slide along the centripetal slide groove 743 in the centripetal direction until the drill 745 returns to its original position;

[0082] First, the same operation as S1.1 is performed to drill several pre-drilled holes of the same depth according to the marked positions of the cracked holes, and then the output end of the motor 71 is directly controlled to rotate in the forward direction through the external control mechanism, so that the ball block 754 moves to the eccentric end of the guide groove 753, and the drill 745 slides along the eccentric direction of the inclined groove 744 and inserts into the soil, and then the motor 71 is controlled to rotate in the reverse direction through the external control mechanism to drill auxiliary holes at the bottom of the pre-drilled holes of the cracked holes. After the auxiliary holes are drilled, cracked holes are formed. The same operation as S1.1 is performed to adjust and reset the drill 745, and the lifting mechanism 4 is used to control the mounting seat A5 to rise, so that the hole expansion assembly 74 is separated from the drilled holes; if there are multiple cracked hole marks, all the cracked holes are drilled in the same way as the above steps;

[0083] S2.3. Collapse and expansion of large geological exploration holes;

[0084] By controlling the moving mechanism 1, the rotating mechanism 2 and the lifting mechanism 4, the bottom end of the cracking mechanism 8 is inserted into the cracking hole until the bottom end of the cracking mechanism 8 contacts the bottom end of the cracking hole, and the hydraulic cylinder 81 is controlled by the external control mechanism, so that the movable end of the hydraulic cylinder 81 drives the connecting shaft 87 to move, so that the movable column 86 moves in the sleeve 83, so that the connecting rod 810 drives the cracking arc plate 88 to slide along the limiting slide groove 841 along the limiting strip 842, and the upper part of the cracking hole is cracked. The auxiliary hole makes it difficult to form a large depression during cracking, and makes cracking easier.
