Description

Technical Field

[0001] The present application relates to the field of rock drilling technology, and in particular to a rock drilling device for engineering geological survey. Background Art

[0002] Engineering geological survey is a crucial prerequisite for geotechnical engineering, mineral resource development, and infrastructure construction. One of its core tasks is to obtain underground core samples or install monitoring devices through rock drilling to assess geological conditions, rock structure, and mechanical properties. However, existing rock drilling equipment still faces significant technical bottlenecks in complex geological environments and diverse engineering requirements. Specifically, the drill bit and drill rod of a traditional drilling rig have poor vibration adaptability in complex formations. The drill bit and drill rod rotate in fracture zones, soft-hard intersecting layers, or underground aquifers. The sudden change in soil hardness causes the resistance encountered by the drill bit to change, and when this resistance is transmitted to the drill rod at the top, it is easy to cause unnecessary vibration of the drill rod. The longer the drill rod, the greater the vibration amplitude. This vibration can cause the drill bit to wobble between the drill bit and the drill rod during drilling, causing the drill bit to rotate in a cone, which seriously affects the continuity and regularity of the borehole, and further causes the borehole to collapse or soil backburial.

[0016] 1. The present invention is equipped with an auxiliary component. When the third hydraulic rod moves downward and to both sides, it pulls the steel cable hinged at its top through the connecting piece. The steel cable will be pulled downward and to both sides, acting on the first movable wheel in the vertical direction and the two second movable wheels in the horizontal direction respectively.

When the drill bit encounters a soil layer, it will rotate to break the soil, and the connecting rod structure formed by the first movable bar and the second movable bar will expand outward under the action of centrifugal force. The rack on the outside of the second movable bar will further expand the diameter of the drill hole in the drilling area where the drill bit is located. When the second movable bar moves, it will be pulled by the movable ring on its top and the fourth spring. The faster the rotation speed of the drill rod and the greater the centrifugal force, the smaller the angle between the second movable bar and the first movable bar, and the larger the diameter of the hole that can be expanded, thereby facilitating geological exploration and sampling.

[0018] 3. The present invention is equipped with a fixing assembly. By increasing the stroke of the third hydraulic rod, the third hydraulic rod drives the triangular cone downward and inserts it into the soil and then stops. Then, the stroke of the second hydraulic rod is increased, and the third hydraulic rods on both sides are pushed outward, so that the triangular cone is embedded in the soil on both sides and then stops. In conjunction with the support assembly, a dual support is formed that is embedded in the ground surface and the soil layer. In addition, the movement of the fixing assembly also serves as an active driving source for the auxiliary assembly, pulling ropes on both sides of the ladder frame to achieve auxiliary fixation.

A drilling assembly 7 is installed in the middle of the fixed assembly 5;

[0033] The auxiliary component 6 is fixedly installed on the top of the two fixed components 5. The auxiliary component 6 includes a ladder frame 61. Two longitudinal frames 62 are fixedly installed on the front and rear sides of the ladder frame 61. Two second springs 63 are elastically connected in the longitudinal frame 62.

[0034] When the third hydraulic rod 53 moves downward and to the sides, it will pull the steel cable 68 hinged at its top through the connecting piece 55. The steel cable 68 will be pulled downward and to the sides, acting on the first movable wheel 64 in the vertical direction and the two second movable wheels 66 in the horizontal direction respectively.

At this time, the first movable wheel 64 and the two second movable wheels 66 arranged in a cross shape pulled by the steel cable 68 will be displaced, compressing the second spring 63 and the third spring 67 respectively. The two springs can be compressed and then elastically restored. This reciprocating process can complete shock absorption.

[0035] The support assembly 1 includes a base plate 11, and first hydraulic rods 12 are installed through the four corners of the base plate 11. The telescopic ends of the four first hydraulic rods 12 are movably hinged to the base 13.

[0036] By increasing the stroke of the four first hydraulic rods 12 and stopping when the base 13 touches the ground, the first supporting function can be achieved;

[0037] The mobile assembly 2 includes a connecting plate 21, with motors 22 fixedly mounted at the four corners of the top of the connecting plate 21. The output shafts of the four motors 22 are connected to circular shafts 23. A long plate is fixedly connected between every two circular shafts 23. Two more circular shafts 23 are fixedly mounted at the bottom of the long plate. The outer edges of the four circular shafts 23 are sleeved with crawlers 24. Two cylinders 25 are fixedly mounted on the top of the connecting plate 21. The top ends of the two cylinders 25 are fixedly connected to the bottom surface of the base plate 11.

[0038] The motor 22 drives the circular shaft 23, which drives the crawler belt 24 to operate, making the entire device movable. The motors 22 on both sides achieve differential steering by changing the speed.

[0039] The driving assembly 3 includes a rectangular frame 31, which is fixedly mounted on the top of the base plate 11. Two sets of telescopic rods 32 are fixedly mounted on the top of the rectangular frame 31. The outer edges of the two sets of telescopic rods 32 are sleeved with first springs 33. Diesel engines 34 are fixedly mounted on the telescopic ends of the two sets of telescopic rods 32. A first runner 35 is mounted on the right side of the diesel engine 34.

[0040] Start the diesel engine 34, which drives the second rotor 42 to rotate clockwise through the first rotor 35 and the transmission belt 43. When the diesel engine 34 is in use, the telescopic rod 32 at the bottom and the first spring 33 can achieve partial shock absorption.

[0041] Among them, the transmission assembly 4 includes a bracket 41, which is fixedly installed in the middle position of the rectangular frame 31, and a fixed block 44 is fixedly installed on the top of the bracket 41. The left end of the fixed block 44 is rotatably installed with a second runner 42, and the outer edge of the second runner 42 is sleeved with a transmission belt 43. The other end of the transmission belt 43 is sleeved with the outer edge of the first runner 35. The right end of the rotating shaft of the second runner 42 is fixedly connected with a transmission rod 45, and the right end of the transmission rod 45 is fixedly connected with a bevel gear set 46. The bevel gear set 46 is divided into a left transverse bevel gear and a right longitudinal bevel gear, which are in a meshing relationship. A sleeve 47 is installed through the middle of the right bevel gear, and a shell 48 is installed on the outer edge of the sleeve 47; the transmission rod 45 is installed through the interior of the fixed block 44, and the left side of the shell 48 is fixedly connected to the bracket 41;

[0042] The diesel engine 34 drives the second rotor 42 to rotate clockwise via the first rotor 35 and the transmission belt 43. The second rotor 42 then transmits the rotational force to the sleeve 47 via the transmission rod 45 and the bevel gear set 46, so that the sleeve 47 can drive the drill rod 71 to rotate clockwise. The top of the drill rod 71 is also equipped with an auxiliary device that presses downward, allowing the drill rod 71 to rotate and move downward.

[0043] The fixing assembly 5 includes a connecting block 51, which is fixedly mounted on the outer edge of the base plate 11. A second hydraulic rod 52 is installed inside the connecting block 51. The second hydraulic rod 52 is bidirectionally telescopic. The two telescopic ends of the second hydraulic rod 52 are fixedly connected to two vertical third hydraulic rods 53. The telescopic ends of the two third hydraulic rods 53 are fixedly connected to triangular cones 54. The tops of the two third hydraulic rods 53 are fixedly mounted with connecting pieces 55. The inner side of the connecting piece 55 is movably hinged with the tail end of the steel cable 68.

[0044] When the support assembly 1 is fixed, the fixing assembly 5 is started again. The stroke of the third hydraulic rod 53 is first increased, so that it drives the triangular cone 54 downward and inserts it into the soil and then stops. Then the stroke of the second hydraulic rod 52 is increased, and the third hydraulic rods 53 on both sides are pushed outward. After that, the triangular cone 54 is embedded in the soil to both sides and stops, completing another support.

[0045] The cam 75 is fixed to the top of the cam 76 and the cam 77 is fixed to the top of the cam 76.

[0046] When the drill bit 72 encounters a soil layer, it will rotate to break the soil, and the connecting rod structure formed by the first movable bar 73 and the second movable bar 74 will expand outward under the action of centrifugal force. The rack on the outside of the second movable bar 74 will further expand the diameter of the drill hole in the drilling area where the drill bit 72 is located. When the second movable bar 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 rod 71, the greater the centrifugal force, the smaller the angle between the second movable bar 74 and the first movable bar 73, and the larger the diameter of the hole that can be expanded.

[0047] Working principle:

[0048] When using the present invention, the device is first moved to the desired location by moving the assembly 2. The device is equipped with electronic components for remote control. The motor 22 drives the circular shaft 23, which drives the crawler 24 to operate, making the entire device movable. The motors 22 on both sides achieve differential steering by changing their rotational speeds.

[0049] When the equipment reaches the designated position, the stroke of the four first hydraulic rods 12 is increased first. When the base 13 touches the ground, the device stops, completing the first support function. When the support assembly 1 is fixed, the fixing assembly 5 is started again. The stroke of the third hydraulic rod 53 is increased first, so that it drives the triangular cone 54 downward and inserts it into the soil, then stops. Then, the stroke of the second hydraulic rod 52 is increased, and the third hydraulic rods 53 on both sides are pushed outward, so that the triangular cone 54 is embedded in the soil to both sides and stops, completing another support function.

[0050] When the third hydraulic rod 53 moves downward and to the sides, it pulls the steel cable 68 hinged to the top of the third hydraulic rod 53 by the connecting piece 55. The steel cable 68 is pulled downward and to the sides, 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 wheel 66 are pulled, the second spring 63 and the third spring 67 are elastically deformed, thereby initiating an auxiliary oblique pulling effect on both sides of the ladder frame 61.

[0051] When the preparation work is completed, the diesel engine 34 is started. The diesel engine 34 drives the second rotor 42 to rotate clockwise through the first rotor 35 and the transmission belt 43. The second rotor 42 then transmits the rotational force to the sleeve 47 through the transmission rod 45 and the bevel gear set 46, so that the sleeve 47 can drive the drill rod 71 to rotate clockwise. An auxiliary device that presses downward is also installed on the top of the drill rod 71, so that the drill rod 71 can rotate and move downward. When the drill bit 72 encounters a soil layer, it rotates to break the soil, and the connecting rod structure formed by the first movable bar 73 and the second movable bar 74 will expand outward under the action of centrifugal force. The rack outside the second movable bar 74 will further expand the diameter of the drill hole in the drilling area where the drill bit 72 is located. When the second movable bar 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 rod 71, the greater the centrifugal force, the smaller the angle between the second movable bar 74 and the first movable bar 73, and the larger the diameter of the hole that can be expanded.

[0052] When the drilling assembly 7 is drilling a hole, vibration will be generated. The vibration generated by the drill rod 71 will be transmitted to the ladder frame 61, and the ladder frame 61 will shake and displace. At this time, the first movable wheel 64 and the two second movable wheels 66 arranged in a cross shape pulled by the steel cable 68 will be displaced, compressing the second spring 63 and the third spring 67 respectively. The two springs can be compressed and then elastically restored, and this reciprocating process can complete shock absorption.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
