Description

Technical Field

[0001] This utility model relates to the field of geological exploration equipment technology, and more specifically, to a support mechanism and a geological drilling device for geological drilling. Background Technology

[0002] Geological drilling is an important means of obtaining information about underground rock and soil strata, and is widely used in mineral resource exploration, engineering geological surveys, and hydrogeological investigations. Existing geological drilling equipment typically includes a drilling rig, drill rods, drill bits, and a support mechanism for fixing and supporting the rig. The main function of the support mechanism is to maintain the stability of the drilling rig during drilling, ensuring the verticality of the borehole and drilling accuracy.

[0003] For example, the specification of the Chinese utility model patent (publication number: CN211715061U) "A support mechanism and geological drilling device for geological drilling" states that: after the telescopic support mechanism extends its screw legs, it forms a stable support platform, which can ensure the smooth operation of the geological drilling equipment installed on it, avoid drilling deviation or drilling failure, and effectively ensure the smooth progress of geological drilling work. Regarding the aforementioned technologies, the support mechanism employs a single motor coupled with sprocket drive to achieve synchronous extension and retraction of multiple outriggers. However, this approach has significant drawbacks in practical engineering applications. The inherent problems of chain drive, such as chain elastic deformation, hinge wear, and uneven tension, easily lead to cumulative deviations in the rotation angles of each driven sprocket, resulting in inconsistent extension lengths of the screw outriggers and causing the support platform to tilt. Furthermore, this transmission scheme couples all outriggers to the same power source, lacking independent adjustment functionality for each outrigger. When the working ground has local undulations, it cannot compensate for differences in foundation elevation by selectively adjusting the extension and retraction of each outrigger, making it difficult to ensure precise horizontal support of the drilling equipment under complex terrain conditions. This severely restricts the equipment's site adaptability and borehole verticality accuracy.

[0004] Therefore, we have made improvements to this and proposed a support mechanism and a geological drilling device for geological drilling. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a support mechanism and a geological drilling device for geological drilling, solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A support mechanism and a geological drilling device for geological drilling include a vehicle body, with support components provided on both sides of the top of the vehicle body, a drilling component provided on the top of the vehicle body, a working hole provided on the top of the vehicle body, and a limit component provided at the upper opening of the working hole on the top of the vehicle body. The support assembly includes swivel shafts symmetrically distributed on both sides of the top of the vehicle body. An extension arm is fixedly installed at the top of the swivel shaft, a hydraulic telescopic rod is fixedly installed at one end of the extension arm, a pressure plate is fixedly installed at the drive end of the hydraulic telescopic rod, a steering mechanism is provided on the top of the vehicle body on one side of the swivel shaft, a level is fixedly installed on the front of the vehicle body, and a displacement sensor is provided on the pressure plate.

[0007] As a preferred technical solution of this application, the drilling assembly includes guide rods fixedly installed on the top of the vehicle body and symmetrically distributed on both sides of the working hole position. A top plate is fixedly installed on the top of the guide rod, and a movable seat is slidably sleeved on the outer wall of the guide rod. A second servo motor is fixedly installed on the top of the movable seat, and a drill rod is rotatably installed on the bottom of the movable seat. The drill rod is fixedly connected to the drive end of the second servo motor. A vertical moving mechanism is provided on the top of the vehicle body behind the working hole position.

[0008] As a preferred technical solution of this application, the vertical moving mechanism includes a vertical rail fixedly installed on the top of the vehicle body behind the working hole. A lead screw is rotatably installed inside the vertical rail. A connecting seat is sleeved on the outer wall of the lead screw. The connecting seat is slidably installed on the vertical rail and is fixedly connected to the movable seat. A third servo motor is fixedly installed at the top of the vertical rail. The driving end of the third servo motor passes through the vertical rail and extends into the interior of the vertical rail. The driving end of the third servo motor is fixedly connected to the top of the lead screw.

[0009] As a preferred technical solution of this application, the limiting component includes two limiting baffles. The two limiting baffles are symmetrically distributed and fixedly installed at the upper port of the working hole on the top of the vehicle body by bolts. Limiting grooves are opened on the opposite sides of the two limiting baffles, and a number of ball bearings are movably installed on the inner wall of the limiting grooves.

[0010] As a preferred technical solution of this application, a storage box is fixedly installed on one side of the top of the vehicle body.

[0011] As a preferred technical solution of this application, the steering mechanism includes a first servo motor fixedly installed on the top of the vehicle body on one side of the rotating shaft, a first gear fixedly installed on the drive end of the first servo motor, and a second gear fixedly installed on the outer wall of the rotating shaft, the second gear meshing with the first gear.

[0012] As a preferred technical solution of this application, symmetrically distributed protective covers are fixedly installed on both sides of the top of the vehicle body, and the steering mechanism is located inside the protective covers.

[0013] As a preferred technical solution of this application, the connecting seat is provided with a threaded hole adapted to the lead screw, and the connecting seat is threadedly connected to the lead screw through the threaded hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By setting up support components, each hydraulic telescopic rod is controlled by an independent hydraulic pipeline. With the help of displacement sensors set on the pressure plate, independent adjustment of each support point can be achieved. This effectively solves the problem in the existing technology where the extension length of each outrigger is inconsistent due to single motor sprocket transmission and cannot be adjusted independently. At the same time, combined with the real-time feedback of the level, the vehicle body can be accurately leveled in complex undulating terrain, ensuring that the drilling equipment is always in a horizontal support state. This significantly improves the site adaptability of the equipment and the verticality accuracy of the borehole, ensuring the smooth and reliable operation of drilling.

[0015] 2. By setting a limiting component, using the limiting grooves and balls opened on the two limiting baffles, the radial swing of the drill rod is effectively constrained without hindering the rotation and feed of the drill rod. Compared with the existing technology that uses a correction screw for manual adjustment, it can continuously play a limiting role without stopping the machine for manual intervention. Moreover, the limiting baffle is fixedly installed at the upper port of the working hole on the top of the vehicle body by bolts. It can be quickly disassembled and replaced according to different sizes of drill rods, with strong adaptability, simple and reliable structure, effectively improving drilling efficiency and drilling quality.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] Example 1 Please refer to Figures 1-6 A support mechanism and geological drilling device for geological drilling are disclosed, comprising a vehicle body 1, support components 2 on both sides of the top of the vehicle body 1, a drilling component 3 on the top of the vehicle body 1, a working hole 7 on the top of the vehicle body 1, a limit component 4 at the upper opening of the working hole 7 on the top of the vehicle body 1, the support component 2 including a rotating shaft 8 symmetrically distributed on both sides of the top of the vehicle body 1, an extension arm 9 fixedly installed at the top of the rotating shaft 8, a hydraulic telescopic rod 10 fixedly installed at one end of the extension arm 9, a pressure plate 11 fixedly installed at the drive end of the hydraulic telescopic rod 10, a steering mechanism on one side of the rotating shaft 8 on the top of the vehicle body 1, a level 5 fixedly installed on the front of the vehicle body 1, and a displacement sensor on the pressure plate 11.

[0022] The device is designed with a combination of vehicle body 1, support assembly 2, drilling assembly 3, limiting assembly 4, working hole position 7, rotating shaft 8, extension arm 9, hydraulic telescopic rod 10, pressure plate 11, level 5, and displacement sensor, which makes it easy to move and can accurately level vehicle body 1 to ensure the stability of drilling operations.

[0023] Furthermore, the drilling assembly 3 includes guide rods 16 fixedly installed on the top of the vehicle body 1 and symmetrically distributed on both sides of the working hole position 7. A top plate 17 is fixedly installed on the top of the guide rods 16. A movable seat 18 is slidably sleeved on the outer wall of the guide rods 16. A second servo motor 19 is fixedly installed on the top of the movable seat 18. A drill rod 20 is rotatably installed on the bottom of the movable seat 18. The drill rod 20 is fixedly connected to the drive end of the second servo motor 19. A vertical moving mechanism is provided on the top of the vehicle body 1 behind the working hole position 7.

[0024] The coordinated arrangement of the guide rod 16, top plate 17, movable seat 18, second servo motor 19, drill rod 20 and vertical moving mechanism ensures that the rotary drilling and vertical feeding actions of the drill rod 20 are separated and coordinated, thus guaranteeing the stability and controllability of the drilling action.

[0025] Furthermore, the vertical moving mechanism includes a vertical rail 21 fixedly installed on the top of the vehicle body 1 behind the working hole 7. A lead screw 22 is rotatably installed inside the vertical rail 21. A connecting seat 23 is sleeved on the outer wall of the lead screw 22. The connecting seat 23 is slidably installed on the vertical rail 21 and is fixedly connected to the movable seat 18. A third servo motor 24 is fixedly installed at the top of the vertical rail 21. The driving end of the third servo motor 24 passes through the vertical rail 21 and extends into the interior of the vertical rail 21. The driving end of the third servo motor 24 is fixedly connected to the top of the lead screw 22.

[0026] The vertical rail 21, lead screw 22, connecting seat 23, and third servo motor 24 are arranged in a coordinated manner, so that the third servo motor 24 can control the number of rotations of lead screw 22, thereby driving the movable seat 18 and drill rod 20 to feed vertically along guide rod 16, ensuring controllable drilling depth.

[0027] Furthermore, the steering mechanism includes a first servo motor 12 fixedly mounted on the top of the vehicle body 1 on one side of the rotating shaft 8. A first gear 13 is fixedly mounted on the drive end of the first servo motor 12, and a second gear 14 is fixedly mounted on the outer wall of the rotating shaft 8. The second gear 14 meshes with the first gear 13.

[0028] Through the coordinated arrangement of the first servo motor 12, the first gear 13, and the second gear 14, the extension arm 9 can automatically swing to the required support position according to the terrain conditions, without the need for manual adjustment, effectively improving the deployment efficiency and automation level of the equipment in complex terrain.

[0029] Furthermore, symmetrically distributed protective covers 15 are fixedly installed on both sides of the top of the vehicle body 1, and the steering mechanism is located inside the protective cover 15.

[0030] By setting up the protective cover 15, the first servo motor 12, the first gear 13 and the second gear 14 of the steering mechanism are enclosed inside it, which effectively prevents dust, gravel and mud generated during drilling operations from contaminating or jamming the transmission components, extending the service life of the steering mechanism and ensuring its transmission reliability.

[0031] Furthermore, the connecting seat 23 has a threaded hole that matches the lead screw 22, and the connecting seat 23 is threadedly connected to the lead screw 22 through the threaded hole.

[0032] The threaded hole on the connecting seat 23 forms a threaded engagement with the lead screw 22, which enables the rotational motion of the lead screw 22 to be efficiently and smoothly converted into the linear motion of the connecting seat 23. This ensures the accuracy and transmission efficiency of the vertical feed action and avoids feed errors caused by transmission backlash.

[0033] Example 2 The geological drilling support mechanism and geological drilling device provided in Embodiment 1 are further optimized. Specifically, the limiting component 4 includes two limiting baffles 25. The two limiting baffles 25 are symmetrically distributed and fixedly installed at the upper port of the working hole 7 on the top of the vehicle body 1 by bolts. Limiting grooves 26 are opened on the opposite sides of the two limiting baffles 25. Several balls 27 are movably installed on the inner wall of the limiting grooves 26.

[0034] By using the combination of the limiting baffle 25, the limiting groove 26 and the ball bearing 27, when the drill rod 20 passes through the working hole 7, the ball bearing 27 forms a rolling contact with the outer wall of the drill rod 20, which effectively limits the radial swing of the drill rod 20 without generating additional resistance to its rotation and feed, thus ensuring the verticality of the drilling and the smoothness of drilling.

[0035] Furthermore, a storage box 6 is fixedly installed on one side of the top of the vehicle body 1.

[0036] The storage box 6 provides dedicated storage space for replacement parts such as drill bits and limit baffles 25 required for drilling operations, making it convenient for operators to quickly access parts of different sizes and improving the convenience and efficiency of on-site operations.

[0037] The following is the usage process of the geological drilling support mechanism and geological drilling device provided by this utility model: After the equipment moves to the designated drilling position via the vehicle body 1, the operator judges the flatness of the current working ground based on the attitude data displayed by the level 5 installed on the vehicle body 1. Then, the steering mechanism in each support assembly 2 is activated. The first servo motor 12 drives the first gear 13 to rotate, which in turn drives the rotating shaft 8 to rotate through the meshing second gear 14, causing the extension arm 9 at the top of the rotating shaft 8 to swing to the preset support position. Subsequently, each hydraulic telescopic rod 10 extends independently, driving the pressure plate 11 at its end to move downwards until it presses against the ground, lifting the vehicle body 1 and removing it from ground contact. Because each hydraulic telescopic rod 10 has independent movement capability, and in conjunction with the stroke data fed back by the displacement sensor installed on the pressure plate 11, the height of each support point can be independently adjusted until the level 5 indicates that the vehicle body 1 is completely level, thus achieving precise leveling support under complex terrain conditions. The cylinder of each hydraulic telescopic rod 10 is fixed to the end of the extension arm 9, and its hydraulic lines are independent, ensuring the reliability of independent adjustment of each leg.

[0038] After the vehicle body 1 is horizontally supported and fixed, the drilling operation begins. The third servo motor 24 starts, driving the lead screw 22 inside the vertical rail 21 to rotate, causing the connecting seat 23 to slide downward along the vertical rail 21. Since the connecting seat 23 is fixedly connected to the movable seat 18, the movable seat 18, guided by the guide rod 16, drives the drill rod 20 downward. At the same time, the second servo motor 19 drives the drill rod 20 to rotate at high speed, cutting and drilling into the formation. When the drill rod 20 passes through the working hole 7 opened at the top of the vehicle body 1, the limiting component 4 located at the upper end of the working hole 7 provides auxiliary constraint on the drill rod 20. The inner sides of the two symmetrically distributed limiting baffles 25 have limiting grooves 26. Several balls 27 movably installed on the inner wall of the limiting grooves 26 form rolling contact with the outer wall of the drill rod 20, effectively limiting its radial swing without hindering the rotation and feed of the drill rod 20, ensuring the verticality of the borehole. Throughout the drilling process, the support component 2 continuously provides a stable horizontal platform, ensuring the accuracy and safety of the drilling operation.
