Description

Technical Field

[0001] This application relates to the technical field of rock drilling, and particularly to a rock stratum drilling device for engineering geological exploration. Background Art

[0002] Engineering geological exploration is an important precondition for geotechnical engineering, mineral resource development, and infrastructure construction. One of its core tasks is to obtain underground rock core samples or install monitoring devices through rock stratum drilling to evaluate geological conditions, rock mass structures, and mechanical properties. However, existing rock stratum drilling devices still have significant technical bottlenecks under complex geological environments and diverse engineering requirements. Specifically, they have poor anti-vibration adaptability in complex strata. The drill bits and drill pipes of traditional drilling rigs rotate in fractured zones, interlayers of hard and soft rocks, or underground aquifers. Due to sudden changes in the hardness of the soil, the resistance received by the drill bit changes. When transmitted to the drill pipe at its top, it is easy to cause excessive vibration of the drill pipe. Moreover, the longer the drill pipe, the greater the vibration amplitude. This part of the vibration will cause yaw between the drill bit and the drill pipe during drilling, making the drill bit rotate in a conical shape, thus seriously affecting the continuity and regularity of the drill hole. Further, it will cause problems such as drill hole collapse or soil backfill. Summary of the Invention

[0014] The beneficial effects of the present invention are as follows: 1. By installing an auxiliary component, during the downward and lateral movement of the third hydraulic rod, the steel cable hinged to its top through the connecting piece will be pulled. The steel cable will be pulled downward and laterally, acting on the first movable wheel in the vertical direction and the two second movable wheels in the horizontal direction respectively. When the first movable wheel and the second movable wheels are pulled, the second spring and the third spring will both undergo elastic deformation, starting an oblique pulling auxiliary effect on both sides of the trapezoidal frame. When the drilling component drills holes, vibrations will be generated. The vibrations generated by the drill rod will be transmitted to the trapezoidal frame, and the trapezoidal frame will undergo jitter displacement. At this time, the first movable wheel and the two second movable wheels arranged in a cross shape and pulled by the steel cable will be displaced, respectively compressing the second spring and the third spring. After the two springs are compressed, they can elastically recover, and so on, to complete shock absorption, solving the problem that the drill bit and drill rod deflect during hard rock drilling, resulting in unsatisfactory drilling.

[0015] 2. The present invention is equipped with a drill bit capable of expanding holes. When the drill bit encounters the soil layer, it will rotate to break through the soil, and the connecting rod structure formed by the first movable strip and the second movable strip will expand outward under the action of centrifugal force. The rack on the outer side of the second movable strip will further enlarge the diameter of the drill hole in the drilling area where the drill bit is located. When the second movable strip moves, it will be pulled by the movable ring and the fourth spring at its top. The faster the rotation speed of the drill rod, the greater the centrifugal force, the smaller the angle between the second movable strip and the first movable strip, and the larger the diameter of the hole that can be expanded, thus facilitating geological exploration and sampling.

[0016] 3. The present invention is equipped with a fixing component. By increasing the stroke of the third hydraulic rod, it drives the triangular cone downward and inserts it into the soil and then stops. Then, by increasing the stroke of the second hydraulic rod, it pushes the third hydraulic rods on both sides to move outward, so that the triangular cone is embedded into the soil on both sides and then stops. Cooperating with the support component, it can form a double support of the surface and the soil layer in an embedded manner. In addition, the movement of the fixing component also serves as the active driving source of the auxiliary component, pulling the ropes on both sides of the trapezoidal frame, thereby realizing auxiliary fixation.

[0022] Working principle: When using the present invention, first, the device is moved to the position where it needs to be used through the moving assembly 2. Electronic components for remote control are installed in the device. The motor 22 drives the round shaft 23 to drive the crawler 24 to operate, so that the whole device can move. The two motors 22 achieve differential steering by changing the rotation speed; When the device reaches the designated position, first increase the stroke of the four first hydraulic rods 12 and stop when the base 13 touches the ground to complete the first supporting function. When the supporting assembly 1 is fixed, then start the fixing assembly 5. First increase the stroke of the third hydraulic rod 53 to drive the triangular cone 54 downward and insert it into the soil and then stop. Then increase the stroke of the second hydraulic rod 52 to push the two third hydraulic rods 53 to move outward, so that the triangular cone 54 is embedded into the soil on both sides and then stop to complete another support; During the downward and outward movement of the third hydraulic rod 53, the steel cable 68 hinged to its top through the connecting piece 55 will be pulled. The steel cable 68 will be pulled downward and outward, acting on the first movable wheel 64 in the vertical direction and the two second movable wheels 66 in the horizontal direction respectively. When the first movable wheel 64 and the second movable wheels 66 are pulled, the second spring 63 and the third spring 67 will both undergo elastic deformation, starting an auxiliary oblique pulling effect on both sides of the trapezoidal frame 61; When the preparation work is completed, start the diesel engine 34. The diesel engine 34 drives the second runner 42 to rotate clockwise through the first runner 35 and the transmission belt 43. The second runner 42 then transmits the rotational force to the sleeve 47 through the transmission rod 45 and the bevel gear set 46, enabling the sleeve 47 to drive the drill pipe 71 to rotate clockwise. An auxiliary device that presses downward is also installed at the top of the drill pipe 71, enabling the drill pipe 71 to rotate and move downward. When the drill bit 72 encounters the soil layer, it will rotate to break the soil, and the connecting rod structure formed by the first movable strip 73 and the second movable strip 74 will expand outward under the action of centrifugal force. The rack on the outside of the second movable strip 74 will further enlarge the diameter of the drill hole in the drilling area where the drill bit 72 is located. When the second movable strip 74 moves, it will be pulled by the movable ring 75 and the fourth spring 76 at its top. The faster the rotation speed of the drill pipe 71, the greater the centrifugal force, the smaller the angle between the second movable strip 74 and the first movable strip 73, and the larger the diameter of the hole that can be enlarged. When the drilling component 7 drills a hole, vibrations will be generated. The vibrations generated by the drill pipe 71 will be transmitted to the trapezoidal frame 61, and the trapezoidal frame 61 will vibrate and displace. At this time, the first movable wheel 64 and the two second movable wheels 66 arranged in a cross shape and pulled by the steel cable 68 will be displaced, respectively compressing the second spring 63 and the third spring 67. After the two springs are compressed, they can elastically recover, and so on, to complete shock absorption.
