Description

Technical Field

[0001] This invention belongs to the field of geological drilling equipment technology, specifically a geological drilling equipment with drilling buffer and correction function. Background Technology

[0002] Geological drilling equipment is a specialized mechanical device used in geological exploration to drive drilling tools to extract physical geological data (such as rock cores, mineral cores, rock cuttings, liquid samples, gaseous samples, etc.) from the ground. The main types include rotary drilling rigs, percussion drilling rigs, in-situ drilling rigs, and core drilling rigs. Furthermore, based on factors such as drilling depth, application, and construction site, geological drilling equipment can be further subdivided. For example, according to drilling depth, it can be divided into surface sampling machines, shallow hole drilling rigs, medium-deep hole drilling rigs, deep hole drilling rigs, and ultra-deep hole drilling rigs; according to application, it can be divided into hydrogeological well drilling rigs, oil drilling rigs, etc.; and according to construction site, it can be divided into surface drilling rigs, tunnel drilling rigs, and submerged drilling rigs, etc.

[0003] Current drilling equipment primarily rotates the drill rod and drill bit as a whole when drilling into rock formations via a drive unit. However, due to the varying strengths of different rock formations, the drill bit experiences different forces, causing the drill bit and drill rod to deviate. This necessitates a buffer correction component, which uses sensors to detect the deviation and then pushes it back to its original position. This method corrects the motor rotor and drill rod, but since the force is borne by the drill bit, long-term deviation correction can cause the connection between the drill bit and drill rod to tilt, become damaged, or loosen, reducing its service life. Therefore, improvements are needed. Summary of the Invention

[0012] Preferably, the limiting rod includes a buffer correction contact rod, a second piston rod, a first spring, and a first one-way valve disc;

[0013] The second piston rod is located at the middle of the inner end of the arc block. The buffer correction contact rod is movably installed at the inner end of the second piston rod. The second piston rod is elastically connected to the inner cavity of the buffer correction contact rod through a first spring. The first one-way valve is located at the inner end of the inner cavity of the second piston rod. The inner end of the buffer correction contact rod is slidably connected to the inner wall of the drill rod through a first sliding groove opened at the outer end of the drill rod.

[0014] Preferably, the arc block is provided with a limiting component located on the outer side of the inner end of the movable block. The limiting component includes a sliding groove, a sliding block, a limiting shaft, and a second spring.

[0015] The sliding groove is fixedly installed inside the arc block, the sliding block is located on the outer side of the inner end of the movable block, the limiting shaft is located inside the top sliding groove, and the outer side of the top part of the sliding block is elastically connected to the inner wall of the sliding groove through a second spring.

[0016] Preferably, a synchronization component is provided on the top of the arc block, the synchronization component including a mounting shaft, a synchronization rotating plate and a fixing block;

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The above technical solution, by setting up a buffer correction mechanism and an oil passage component, ensures that when the drilling assembly is driven to rotate by the drilling drive device and tilts while drilling rock strata of different strengths, the inner end of the buffer correction mechanism is subjected to tilting force. This causes the hydraulic oil inside to enter the inner end of the other corresponding buffer correction mechanism through the oil passage component, thus transmitting the pressure of the hydraulic oil to the inner end of the corresponding buffer correction mechanism. Ultimately, this keeps the forces at the two corresponding inner ends of the buffer correction mechanism balanced, ensuring that the drilling part of the drilling assembly is subjected to uniform force, avoiding and reducing damage, and greatly improving service life.

[0024] This invention, by setting up a positioning component and a second ball bearing rod, allows for the adjustment and limitation of the movement distance of the outer end of the buffer correction mechanism according to different drill bit sizes. The design of the second ball bearing rod improves the smoothness of the overall downward movement of the drilling component. Finally, the combination of the buffer correction mechanism and the positioning component can limit the drilling of holes with various drill bits, thereby increasing the overall application range of the device.

[0025] This invention sets up a limiting component and a synchronization component. The limiting component can limit the movement of the two sides of the outer end of the buffer correction mechanism. When adjusting the movement range of the outer end of the buffer correction mechanism to accommodate drill bits of different sizes, the synchronization component can keep the movement distance of the two sides of the outer end of the buffer correction mechanism equal, thereby enabling the two sides of the outer end of the buffer correction mechanism to move smoothly and synchronously, and improving the accuracy of the overall diameter change of the buffer correction mechanism.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1 to 12 As shown, the present invention provides a geological drilling equipment with drilling buffer correction function, including a drilling machine body 1, and further including: a support frame 3, the support frame 3 being disposed on one side of the top of the drilling machine body 1; a drilling drive device 4, the drilling drive device 4 being slidably mounted on one side of the support frame 3; a fixed sleeve 5, the fixed sleeve 5 being disposed at the bottom of the drilling drive device 4; a drilling assembly 6, the drilling assembly 6 being disposed at the bottom of the output end of the drilling drive device 4; and a buffer correction mechanism 7, the buffer correction mechanism 7 being disposed at the bottom of the fixed sleeve 5; wherein, the buffer correction mechanism 7 includes... The device includes an arc block 701 movably mounted on the bottom of a fixed sleeve 5. A movable block 702 is movably mounted on the outer end of the arc block 701. A second ball bearing rod 12 is provided on the outer side of the arc block 701. A limiting member 703 is movably mounted inside the fixed sleeve 5 at the inner end of the arc block 701. An oil delivery assembly 704 is located inside the movable block 702 at the inner end of the arc block 701. A limiting rod 705 is located inside the limiting member 703 at the inner end of the limiting member 703. The limiting rods 705 are connected to each other through an oil delivery assembly 13.

[0041] When the limiting rod 705 at a certain position is subjected to the force generated by the offset of the drilling assembly 6, the lubricating oil inside the limiting rod 705 will be introduced into the corresponding limiting rod 705 through the oil supply assembly 13, so that the hydraulic pressure at the other end increases, thereby balancing the forces on both ends, balancing the forces on the drilling part of the drilling assembly 6, and assisting in correction and buffering.

[0042] like Figure 1 As shown, the outer end of the drilling machine body 1 is provided with a fixing mechanism 2, and the number of fixing mechanisms 2 is four.

[0043] The above scheme is adopted: by designing four drilling drive devices 4, auxiliary support and fixation can be provided when the drilling machine body 1 is moved to the designated drilling position.

[0044] like Figure 3 As shown, the drilling assembly 6 includes a drill pipe 601 and a drill bit 602;

[0045] The drill rod 601 is fixedly installed at the bottom of the output end of the drilling drive device 4, and the drill bit 602 is threaded onto the bottom of the drill rod 601.

[0046] The above solution involves a drill bit 602, the size of which is not fixed and can be changed according to different drilling conditions.

[0047] like Figure 3 As shown, the inner wall of the fixed sleeve 5 is provided with a sealing ring 14 located above the drill bit 602. The sealing ring 14 is made of EPDM rubber.

[0048] The above solution is adopted because EPDM rubber has good wear resistance and weather resistance, and can maintain elasticity over a wide temperature range. This allows the drill bit 602 and drill rod 601 to maintain a sealing effect between the fixed sleeve 5 and drill rod 601 even when they rotate and shift as a whole and when high temperatures are generated.

[0049] like Figure 7 As shown, the oil delivery assembly 704 includes an oil delivery cylinder 7041, a first piston rod 7042, and an oil passage pipe 7043;

[0050] The oil delivery cylinder 7041 is fixedly installed inside the arc block 701. The first piston rod 7042 is movably installed at both ends of the inner cavity of the oil delivery cylinder 7041. The outer end of the oil pipe 7043 is fixedly connected to the inner end of the movable block 702. The inner end of the oil delivery cylinder 7041 is connected to the inside of the limiting rod 705 through the oil pipe 7043.

[0051] The above solution is adopted: by setting a first piston rod 7042, when the movable block 702 moves in opposite directions, the first piston rod 7042 will drive the hydraulic oil inside the oil cylinder 7041 to be introduced into the limit rod 705 through the oil pipe 7043 or the hydraulic oil inside the limit rod 705 will be drawn away.

[0052] like Figure 7 As shown, the limiting rod 705 includes a buffer correction contact rod 7051, a second piston rod 7052, a first spring 7053, and a first one-way valve disc 7054;

[0053] The second piston rod 7052 is located at the middle of the inner end of the arc block 701. The buffer correction contact rod 7051 is movably installed at the inner end of the second piston rod 7052. The second piston rod 7052 is elastically connected to the inner cavity of the buffer correction contact rod 7051 through the first spring 7053. The first one-way valve 7054 is located at the inner end of the inner cavity of the second piston rod 7052. The inner end of the buffer correction contact rod 7051 is slidably connected to the inner wall of the drill rod 601 through the first sliding groove 8 opened at the outer end of the drill rod 601.

[0054] The above solution utilizes the elasticity design of the first spring 7053 to buffer the movement of the buffer correction contact rod 7051 due to pressure, greatly reducing the pressure on the buffer correction contact rod 7051 and minimizing damage.

[0055] like Figure 10 As shown, the arc block 701 is provided with a limiting component 9 located on the outer side of the inner end of the movable block 702. The limiting component 9 includes a sliding groove 901, a sliding block 902, a limiting shaft 903, and a second spring 904.

[0056] The sliding groove 901 is fixedly installed inside the arc block 701, the sliding block 902 is located on the outer side of the inner end of the movable block 702, the limiting shaft 903 is located inside the top sliding groove 901, and the outer side of the top part of the sliding block 902 is elastically connected to the inner wall of the sliding groove 901 through the second spring 904.

[0057] The above solution is adopted: by setting a second spring 904, the second spring 904 is in a stretched state. When the arc block 701 as a whole needs to be moved outward for adjustment, the tension of the second spring 904 will be released, thereby pulling the sliding block 902 and the movable block 702 outward.

[0058] like Figure 12 As shown, a synchronization component 10 is provided on the top of the arc block 701. The synchronization component 10 includes a mounting shaft 101, a synchronization rotating plate 102, and a fixing block 103.

[0059] The mounting shaft 101 is located inside the top of the arc block 701. The synchronous rotating plate 102 is movably sleeved on the top of the mounting shaft 101. The fixing block 103 is located on the top of the top sliding block 902. The bottom ends of the synchronous rotating plate 102 are slidably connected to the inside of the fixing block 103.

[0060] By adopting the above scheme: by setting up a synchronous rotating plate 102, the two fixed blocks 103, sliding blocks 902 and movable blocks 702 can be made to maintain the same distance during telescopic movement by the mounting shaft 101 and the synchronous rotating plate 102.

[0061] like Figure 4 As shown, a positioning component 11 is provided at the bottom of the arc block 701. The positioning component 11 includes a connecting block 1101, a second slide groove 1102 and a first ball rod 1103.

[0062] The connecting block 1101 is fixedly installed on the bottom of the arc block 701, the second slide groove 1102 is opened on the top of the drill bit 602, and the first ball rod 1103 is designed on the bottom of the connecting block 1101. The first ball rod 1103 is slidably connected to the inside of the second slide groove 1102.

[0063] By adopting the above scheme, when the position of the second slide groove 1102 at the top of the drill rod 601 of different sizes changes, the first ball rod 1103 and the connecting block 1101 can move synchronously as a whole, thereby limiting the position of the arc block 701 as a whole.

[0064] like Figure 5 As shown, the oil supply assembly 13 includes a delivery pipe 1301 and a second one-way valve 1302;

[0065] The delivery pipe 1301 connects two corresponding buffer correction contact rods 7051, and the second one-way valve 1302 is located at the end of the delivery pipe 1301.

[0066] The above solution is adopted: by setting up a delivery pipe 1301, when the internal movement of the buffer correction contact rod 7051 occurs, the internal hydraulic oil will enter the delivery pipe 1301 and push the two second one-way valves 1302 to open and be introduced into the corresponding limit rod 705. The material of the delivery pipe 1301 is not fixed and can be designed according to the actual situation to avoid affecting the movement of the buffer correction contact rod 7051.

[0067] Working principle and usage process of this invention:

[0068] First, when installing drill bits 602 of different sizes, the movable arc block 701, connecting block 1101, and first ball rod 1103 are moved together until the first ball rod 1103 is smoothly inserted into the second slide groove 1102 at the top of the drill bit 602 of the corresponding size. When the arc block 701 moves, it will squeeze the movable block 702 into place or be pulled by the second spring 904 to extend the sliding block 902 and the movable block 702. This causes the first piston rod 7042 to slide on the inner wall of the oil cylinder 7041. The oil cylinder 7041 drives the first one-way valve 7054 to open through the first piston rod 7042. This allows the hydraulic oil in the inner cavity of the oil cylinder 7041 to be drawn away from the inner cavity of the buffer correction contact rod 7051 through the oil pipe 7043 or to be introduced into the inner cavity of the buffer correction contact rod 7051, so that the second piston rod 7052 can move smoothly.

[0069] When the movable block 702 moves in a telescopic manner, the fixed block 103 will move towards or away from each other. At this time, the ends of the synchronous rotating plate 102 will slide along the inside of the fixed block 103, causing the synchronous rotating plate 102 to rotate. Due to the limiting effect of the mounting shaft 101, the synchronous rotating plate 102 can rotate around the center of the mounting shaft 101, so as to limit the telescopic movement of the fixed blocks 103, sliding block 902 and movable block 702 on both sides to the same distance.

[0070] Subsequently, when the operator controls the drilling rig 1 to move to the designated position for drilling, the fixing mechanism 2 can be controlled to position and fix the drilling rig 1. Then, the support frame 3 is controlled to drive the drilling drive device 4 to move downwards. When the drilling drive device 4 is activated to drive the drill rod 601 and drill bit 602 to rotate, the drill bit 602 can smoothly drill into the rock formation. When drilling into rock formations of different strengths, the drill bit 602 will encounter huge pressure on one side, causing the drill bit 602 and drill rod 601 to tilt. This causes the buffer correction contact rod 7051 to be squeezed and moved, thus reducing the pressure. Hydraulic oil inside the correction contact rod 7051 is squeezed into the delivery pipe 1301 by the second piston rod 7052, pushing the second one-way valve 1302 to open. Finally, the hydraulic oil is introduced into the corresponding end of the buffer correction contact rod 7051 through the delivery pipe 1301, which increases the pressure of the corresponding end buffer correction contact rod 7051. This balances the pressure on the two ends of the buffer correction contact rod 7051. The first spring 7053 can buffer the pressure on the buffer correction contact rod 7051, ultimately balancing the pressure and allowing the drill bit 602 and drill pipe 601 to be smoothly corrected as a whole.
