Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine geological exploration equipment, and in particular relates to a drilling device for coal mine geological testing. Background Technology

[0002] Coal mine geological testing involves systematically investigating parameters such as geological structure, coal seam characteristics, gas content, and hydrological conditions within a coal mine area using techniques such as drilling, geophysical exploration, and geochemical exploration. Drilling samples can analyze coal seam thickness, coal quality, and distribution range to determine recoverable reserves and economic value. It can also detect the location and scale of faults, folds, and fracture zones. If large faults exist within the mine area, the mining area needs to be adjusted or backfilling mining techniques should be adopted to prevent groundwater inrush accidents caused by faults. Drilling can also detect gas content, pressure, groundwater level, and flow velocity to determine whether a coal mine is a "high-gas mine" or a "complex hydrogeological mine," allowing for the early development of gas drainage and waterproof coal pillar plans.

[0003] Chinese utility model patent CN223034928U discloses a coal mine geological drilling device, including a support plate, hydraulic rods, a horizontal plate, and a drill rod. Two sets of hydraulic rods are symmetrically arranged about the support plate above it. Connecting plates are welded to both sides of each hydraulic rod. The connecting plate below the hydraulic rods is connected to the support plate via countersunk bolts, and the connecting plate above the hydraulic rods is connected to the horizontal plate via countersunk bolts. A rotary motor is screwed to the top of the horizontal plate, and the output shaft of the rotary motor is connected to the drill rod via a coupling. The drill rod penetrates both the horizontal plate and the support plate. Two sets of fixing mechanisms are connected to the two symmetrically arranged sides of the support plate. This coal mine geological drilling device can not only adapt to dry geology and moisten the soil, but also drill to greater depths on the ground, improving overall stability.

[0004] However, the direction of geological testing boreholes is usually divided into vertical, horizontal, and inclined. For example, vertical upward drilling is used for exploring the roof underground, while horizontal drilling is used for tunnel exploration and gas extraction. If the target strata are inclined or obstacles need to be avoided, inclined drilling is used. The choice of different directions is determined by the detection target, rather than a single "downward" mode. The traditional drilling device mentioned above cannot meet the complex detection scenarios and multi-functional detection needs due to its single drilling direction. Coal mines need to invest in detection equipment in other directions (such as horizontal drilling rigs and upward drilling rigs), which reduces detection efficiency and increases equipment maintenance costs. Therefore, it is necessary to design a drilling device for coal mine geological testing with adjustable drilling direction. Utility Model Content

[0005] The purpose of this invention is to control the drilling angle, direction, and height of the drilling rig by setting an angle adjustment motor, a direction adjustment motor, and a lifting mechanism, thereby achieving adjustable drilling direction of the drilling equipment. This solves the problem in the background art where traditional drilling devices have a single drilling direction, which cannot meet the complex detection scenarios and multi-functional detection needs, and coal mines need to invest in additional detection equipment in other directions.

Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] See Figures 1 to 6 This embodiment discloses a drilling device for coal mine geological testing, including a base 1. In this embodiment, the base 1 has a rectangular cross-section. A moving mechanism 2 is provided at the bottom of the base 1, which is responsible for moving the drilling device. An angle adjusting motor 3 is installed on the upper surface of the base 1. The drive shaft of the angle adjusting motor 3 is connected to a drive gear 31. A support seat 4 is rotatably connected to the base 1. The support seat 4 is provided with a driven gear 41. The angle adjusting motor 3 controls the horizontal rotation angle of the support seat 4 through the meshing of the drive gear 31 and the driven gear 41. A lifting mechanism 5 is installed on the upper surface of the support seat 4. A support member 51 is provided at the top of the lifting mechanism 5. The lifting mechanism 5 controls the lifting and lowering of the support member 51. A direction adjusting motor 6 is installed on the support member 51 for direction adjustment. The drive shaft of motor 6 is connected to base 61. In this embodiment, a flange is fixedly provided at the top of the drive shaft, and a flange is also fixedly provided on the side of base 61. The drive shaft and base 61 are fixedly connected by the two flanges. The rotation of the drive shaft drives the base 61 to rotate. The rotation angle of base 61 in the vertical direction is controlled by the direction adjustment motor 6. Drilling machine 7 is slidably connected to base 61. Drilling machine 7 is equipped with drill rod 71. When the drilling equipment is in use, the drilling angle of drill rod 71 in the horizontal direction is adjusted by the angle adjustment motor 3, the drilling height of drill rod 71 is adjusted by the lifting mechanism 5, and the drilling angle of drill rod 71 in the vertical direction is adjusted by the direction adjustment motor 6, so that the drilling equipment can meet the complex detection scenarios and multi-functional detection needs of coal mines.

[0021] In this embodiment, the angle adjustment motor 3 and the direction adjustment motor 6 are AC asynchronous motors. By using frequency conversion speed regulation, the rotation speed can be controlled to achieve low-speed operation, which facilitates the adjustment of angle and direction.

[0022] The moving mechanism 2 is a tracked walking mechanism. In this embodiment, the tracked walking mechanism includes components such as tracks, drive wheels, guide wheels, track rollers, support rollers, and tensioning devices. It moves by the friction between the tracks and the ground. It can be further optimized by having differential steering function. The connection method and working principle of each component of the tracked walking mechanism are well known to those skilled in the art and can all adopt existing technical solutions, which will not be described in detail in this application.

[0023] The upper surface of the base 1 has a chamber 11 with a top opening. The chamber 11 is equipped with a protective cover 12. The upper surface of the protective cover 12 has a shaft hole 121. The bottom of the support base 4 has a shaft 42 that matches the shaft hole 121. It can be further optimized that the shaft 42 and the shaft hole 121 are connected by a bearing to improve the smoothness of the support base 4 when rotating. The bottom of the shaft 42 has a driven gear 41. The upper surface of the protective cover 12 has a shaft hole 122 that matches the drive shaft of the angle adjustment motor 3. It can be further optimized that a countersunk platform is provided at the edge of the opening of the chamber 11. The protective cover 12 is adapted to the countersunk platform. After the protective cover 12 is closed, the upper surface of the protective cover 12 is flush with the upper surface of the base 1. The protective cover 12 and the countersunk platform are assembled together with fastening bolts. When the drilling equipment is in use, the driving gear 31 and the driven gear 41 are both located in the chamber 11. The coal slag in the working environment will not affect the meshing of the driving gear 31 and the driven gear 41, causing the gears to jam.

[0024] The lifting mechanism 5 is a hydraulic telescopic rod mechanism 1. The top end of the piston rod 1 in the hydraulic telescopic rod mechanism 1 is fixedly connected to the support 51. The hydraulic telescopic rod mechanism 1 controls the lifting height of the drilling rig 7.

[0025] The support member 51 is provided with a guide hole 511, and the upper surface of the support base 4 is provided with a guide rod 43 that matches the guide hole 511. The support member 51 achieves a sliding connection with the guide rod 43 through the cooperation of the guide hole 511 and the guide rod 43. The guide rod 43 provides a stable displacement stroke for the support member 51 during the lifting and lowering process, and can bear the lateral force of the support member 51, thereby enhancing the structural rigidity.

[0026] The top of the guide rod 43 is provided with a limiting member 431. The outer diameter of the limiting member 431 is larger than the inner diameter of the guide hole 511. The limiting member 431 prevents the support member 51 from falling off the top of the guide rod 43 when it is lifted.

[0027] The machine base 61 has a rectangular cross-section. The upper and lower surfaces of the machine base 61 are provided with linear grooves 62. The machine base 61 is slidably connected to a sliding member 72. The sliding member 72 is provided with a slot 721 that is adapted to the machine base 61. The slot 721 is provided with a protrusion 722 that is matched with the linear groove 62. The drilling rig 7 is installed on the sliding member 72. The sliding connection between the drilling rig 7 and the machine base 61 is realized by the cooperation of the slot 721 and the protrusion 722. The drilling depth is controlled by the position of the drilling rig 7 on the machine base 61 and the length of the drill rod 71.

[0028] A hydraulic telescopic rod mechanism 2 63 is installed on the side of the base 61. The front end of the piston rod 2 in the hydraulic telescopic rod mechanism 2 63 is fixedly connected to the rear end of the sliding member 72. When the drill rod 71 is drilling, the piston rod 2 pushes the sliding member 72 forward to perform the drilling operation, and the drilling depth can be controlled according to the extension length of the piston rod 2.

[0029] The base 1 is equipped with several hydraulic telescopic rod mechanisms 13. The piston rod 131 of the hydraulic telescopic rod mechanism 13 has a support plate 132 at its bottom end. In this embodiment, there are four hydraulic telescopic rod mechanisms 13, which are located at the four corners of the base 1. During drilling, the piston rod 131 moves downward until the lower surface of the support plate 132 contacts the ground, and the moving mechanism 2 is separated from the ground to ensure the stability of the equipment during drilling and prevent the equipment from moving due to the vibration generated during drilling.

[0030] The upper surface of the base 1 is provided with a hydraulic telescopic rod mechanism 14. The top of the piston rod 141 in the hydraulic telescopic rod mechanism 14 is provided with a stabilizing plate 142. When drilling is carried out in the mine or underground, the piston rod 141 rises and presses against the top of the mine. Through the cooperation of the hydraulic telescopic rod mechanism 13 and the hydraulic telescopic rod mechanism 14, the drilling equipment is further stabilized.

[0031] In this embodiment, hydraulic telescopic rod mechanism one, hydraulic telescopic rod mechanism two 63, hydraulic telescopic rod mechanism three 13 and hydraulic telescopic rod mechanism four 14 respectively include a hydraulic cylinder body, a hydraulic power unit, a hydraulic control valve group and a hydraulic pipeline system. The hydraulic cylinder body is composed of a cylinder barrel, a piston, a piston rod and an end cap. The connection method and working principle of each component of the mechanism are well known to those skilled in the art and can all adopt existing technical solutions, which will not be described in detail in this application.

[0032] Working principle: When using the drilling equipment, the moving mechanism 2 places the drilling equipment in the drilling operation position. The drilling equipment is stabilized by the cooperation of the hydraulic telescopic rod mechanism 3 13 and the hydraulic telescopic rod mechanism 4 14. The angle adjustment motor 3 adjusts the horizontal angle of the drill rod 71, the direction adjustment motor 6 adjusts the vertical angle of the drill rod 71, and the lifting mechanism 5 adjusts the height of the drill rod 71, so as to achieve the purpose of adjustable drilling direction of the drilling equipment.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
