Description

Technical Field

[0001] The present invention relates to the field of drilling equipment, and in particular to a drilling equipment and a drilling method for mineral geological exploration. Background Art

[0002] Drilling equipment is a general term for mechanical devices and equipment used in drilling construction. It is mainly composed of the following parts: Power machine: It is the power source of the whole machine, using internal combustion engine, electric motor or hydraulic motor; Rotator or power head: The rotator is driven by the gearbox, and the power head is driven by hydraulics to drive the drill tool to rotate; Bottom hole pressurization and feeding device: Generally hydraulic control is adopted, and the drill tool is pressurized or depressurized through the digital indication of the instrument; Drill tower: It is used to raise and lower drill tools, casing strings and suspend drill tools, and it is required to have sufficient load-bearing capacity and rigidity. The engine or motor transmits power to the drill bit and drill pipe through the transmission system, so that it rotates and moves up and down. The drill pipe is usually composed of two parts: the pipe body and the joint. The pipe body is generally made of seamless steel pipe, and the wall thickness varies according to different usage requirements. The joint part is used to connect each single drill pipe, which is divided into male joint and female joint, which is connected to the two ends of the drill pipe body, and the male joint and the female joint are connected by threads.

[0003] Chinese patent CN101603411B discloses a drilling device and a drilling method, wherein a drilling element is caused to rotate and move along a derrick by a drilling drive device, the drilling element having a continuous auger arranged below the drilling drive device, and an extension part connected to the continuous auger and extending upward through the drilling drive device, a displacement head is arranged between the continuous auger and the extension part, and is suitable for forcing soil materials into the borehole wall;

[0004] The above patents and prior art also have the following defects:

[0005] The drill rods are connected by threads. During the process of lifting the drill rods out of the borehole and removing them, the drill rods in the borehole are prone to shaking and vibrating, causing the two drill rods to rotate relative to each other, and the connection to loosen or even fall off, resulting in the drill rod being retained in the borehole, causing construction accidents and affecting the construction progress. The existing drill rod locking device needs to be locked manually. The drill rod is large in size and weight, and locking is laborious and takes a long time to operate. At the same time, in order to prevent excessive wear and excessive displacement of the drill rod caused by the close contact between the drill rod and the borehole wall, the existing drill bit diameter is often larger than the drill rod diameter, causing the longer drill rod to shake and vibrate in the borehole during construction, resulting in unstable drill rod, poor drilling quality, and easy rod breakage accidents.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1: Reference Figure 1-14 A drilling device shown includes a drilling frame 1, a driving assembly 2, a plurality of drill rods 3 and a drill bit 4. The drill rod 3 can be installed on the driving assembly 2, the drill bit 4 can be installed on the drill rod 3, and the plurality of drill rods 3 can be connected to each other;

[0049] The top of the drill rod 3 is provided with an anti-drop assembly 5, which includes a plurality of anti-drop units 51, and the anti-drop unit 51 includes an anti-drop plate 511. The bottom of the drill rod 3 is provided with an anti-drop block 6, and the anti-drop block 6 is provided with an anti-drop slot;

[0050] A support assembly 7 is provided at the top of the drill pipe 3. The support assembly 7 includes a casing 71 and a support unit 72. The support unit 72 includes a support spring 721. The support spring 721 is provided on the casing 71. The casing 71 can rotate.

[0051] The drilling frame 1 is also provided with an adjustment assembly 8, which can drive the bottom of the anti-drop plate 511 and the supporting spring piece 721 to move vertically respectively.

[0052] The driving assembly 2 drives the drill rod 3 to rotate and move downward, and the drill rod 3 drives the drill bit 4 to rotate and move into the soil. When the drill rod 3 rotates and descends in the soil, the supporting spring piece 721 abuts against the inner wall of the drilled hole to maintain the stability of the drill rod 3. The drill rod 3 rotates in the casing 71. When most of the drill rod 3 on the driving assembly 2 enters the soil, the drill rod 3 and the driving assembly 2 are disassembled, and the driving assembly 2 moves upward to reset, and a new drill rod 3 is installed on the driving assembly 2. The bottom of the new drill rod 3 is installed on the top of the drill rod 3 in the soil. At this time, the anti-slip assembly 5 at the top of the drill rod 3 below corresponds to the anti-slip block 6 at the bottom of the drill rod 3 above. At this time, the adjustment assembly 8 drives the bottom of the supporting spring piece 721 to move upward, so that the supporting spring piece 721 undergoes elastic deformation until the diameter of the circular structure formed by the plurality of supporting spring pieces 721 arranged in a circle is consistent with the diameter of the drill bit 4. Then the adjustment assembly 8 drives the anti-slip plate 511 to move upward, and the anti-slip plate 511 on the lower drill rod 3 enters the anti-slip groove on the upper drill rod 3.

[0053] When the two drill rods 3 are connected to each other, the anti-drop plate 511 moves upward and is inserted into the anti-drop groove on the other drill rod 3, so that the two drill rods 3 will not rotate relative to each other and cause them to fall off, thereby reducing drilling accidents. During the rotation of the drill rods 3, the supporting spring piece 721 abuts against the inner wall of the borehole to prevent the longer drill rod 3 from shaking and vibrating in the borehole, and prevent the drill rod 3 from breaking and separating from the connection due to shaking and vibration, thereby ensuring drilling safety, improving the stability of the drill rod 3 and the drill bit 4, and improving the drilling quality.

[0054] The adjustment component 8 can adjust the diameter of the circular structure formed by multiple supporting spring pieces 721 to make it consistent with the diameter of the drill bit 4, so that the supporting spring pieces 721 can adapt to drill bits 4 of different diameters and can offset the inner wall of the borehole drilled by drill bits 4 of different diameters, providing stability to the drill rod 3 and better adaptability.

[0055] When the drill rod 3 moves in the borehole, the supporting spring piece 721 may deform to a certain extent when encountering protruding stones, etc., thereby reducing wear and preventing the drill rod 3 from getting stuck. When drilling, the drill rod 3 rotates in the casing 71, and the supporting spring piece 721 resists against the inner wall of the borehole and does not rotate, thereby preventing the supporting spring piece 721 from rotating for a long time and rubbing against the inner wall of the borehole, which may cause rapid wear of the supporting spring piece 721, thereby improving the stability and service life of the supporting spring piece 721.

[0075] Example 9, reference Figure 1-Figure 14 , which is different from the above embodiment, a drilling seat 14 is fixedly installed on the drilling frame 1, a drilling hole is opened on the drilling seat 14, a rotating cylinder 81 is rotatably connected to the drilling seat 14, an adjustment motor 84 is fixedly installed on the drilling seat 14, two brake cylinders 15 are fixedly installed on the drilling seat 14, a brake block 16 is fixedly installed on the output end of the brake cylinder 15, and an anti-slip groove is opened on the brake block 16.

[0076] The brake cylinder 15 drives the brake block 16 to move and clamp the drill rod 3 located below. When the hydraulic motor 22 drives the drill rod 3 above to rotate, the drill rod 3 located below will not rotate, and the connecting screw 13 on the upper drill rod 3 is rotated and screwed into the anti-detachment tube 54. When the connection is tight, the anti-detachment plate 511 on the anti-detachment tube 54 of the lower drill rod 3 corresponds to the anti-detachment groove on the anti-detachment block 6 of the upper drill rod 3. At the same time, when disassembling, the drill rod 3 in the soil will not fall into the hole.

[0077] A drilling method for mineral geological exploration, using the above-mentioned drilling equipment, comprises the following steps:

[0078] The driving assembly 2 drives the drill rod 3 to rotate and move downward, and the drill rod 3 drives the drill bit 4 to rotate and move into the soil;

[0079] When the drill rod 3 rotates and descends in the soil, the supporting spring piece 721 abuts against the inner wall of the drilled hole to maintain the stability of the drill rod 3, and the drill rod 3 rotates in the casing 71;

[0080] When most of the drill rod 3 on the driving assembly 2 has entered the soil, the drill rod 3 and the driving assembly 2 are disassembled;

[0081] The driving assembly 2 moves upward to reset, and a new drill rod 3 is installed on the driving assembly 2. The bottom of the new drill rod 3 is installed on the top of the drill rod 3 in the soil. At this time, the anti-slip assembly 5 at the top of the drill rod 3 below corresponds to the anti-slip block 6 at the bottom of the drill rod 3 above.

[0082] At this time, the adjustment component 8 drives the bottom of the supporting spring piece 721 to move upward, so that the supporting spring piece 721 undergoes elastic deformation, until the diameter of the circular structure formed by the plurality of supporting spring pieces 721 arranged in a circle is consistent with the diameter of the drill bit 4;

[0083] Afterwards, the adjustment assembly 8 drives the anti-slip plate 511 to move upward, and the anti-slip plate 511 on the lower drill rod 3 enters the anti-slip groove on the upper drill rod 3 .
