Description

Technical Field

[0001] This invention relates to the field of coal mine geological exploration technology, and in particular to a geological exploration drilling device. Background Technology

[0002] Geological drilling refers to a geological engineering process that uses certain drilling machinery and technology to obtain rock cores below the surface in order to make reliable evaluations of geological and mineral resource parameters. During the geological drilling process, the cylindrical drill bit rotates and breaks the rock at the bottom of the well, leaving a columnar rock core in the center of the bottom of the hole. The rock core is then taken out of the hole to study the geological and mineral resource conditions. The geological conditions of coal mine goaf areas play a crucial role in the subsequent mining, safe production, and protection of the surrounding environment. Therefore, there is a particular need for geological exploration drilling equipment for coal mine goaf areas.

[0003] However, existing geological exploration drilling equipment has poor drilling stability in complex goaf environments. Since the geological structure of the goaf may have been damaged, borehole collapse is prone to occur during the drilling process, which affects the smooth progress of the drilling work.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0054] The following is combined with Figures 1 to 9 The structure and working principle of the geological exploration drilling equipment of the present invention are described in detail.

[0055] like Figures 1 to 9 As shown, a specific embodiment of the present invention provides a geological exploration drilling device. The geological exploration drilling device includes a drilling mechanism 8; the drilling mechanism 8 includes a drilling component 82, an elastic component 813, and a support component 81; the drilling component 82 has a spring groove 812 formed radially; the elastic component 813 is installed in the spring groove 812 and connected to the drilling component 82; the support component 81 is at least partially located on the outside of the drilling component 82; one end of the support component 81 is connected to the elastic component 813, and the other end is used to abut against the inner wall of the borehole; the elastic component 813 is used to press the support component 81 against the inner wall of the borehole.

[0056] In this embodiment, by setting the elastic component 813 and the support component 81, when the drilling component 82 is inserted into the borehole, the elastic component 813 can press the support component 81 against the inner wall of the borehole, thereby supporting the borehole. This solves the problem in the prior art that the borehole has poor stability and is prone to collapse when drilling.

[0057] Furthermore, multiple spring grooves 812 are spaced apart along the axial direction of the drilling assembly 82. Each spring groove 812 corresponds to a different elastic component 813 and a support component 81, further enhancing the support force on the borehole.

[0058] Preferably, multiple spring grooves 812 are arranged at intervals along the spiral direction on the side of the drilling assembly 82.

[0059] Furthermore, the support assembly 81 includes a limiting block 814 and a support block 815; one side of the limiting block 814 is connected to the elastic assembly 813 and slides in a radial engagement with the spring groove 812 along the drilling assembly 82; the support block 815 is formed on the side of the limiting block 814 away from the elastic assembly 813; at least a portion of the support block 815 is located on the outer side of the drilling assembly 82; the elastic assembly 813 presses the support block 815 against the inner wall of the borehole through the limiting block 814. By setting the limiting block 814, a guiding function is achieved, which can improve the movement stability of the support block 815.

[0060] Furthermore, the drilling assembly 82 includes a drill rod drive 817, a rotating rod 809, a drill rod 811, and a circumferential limiting component. One end of the rotating rod 809 is connected to the drill rod drive 817. The rotating rod 809 is sleeved on the outside of the drill rod 811 and threadedly assembled with the drill rod 811. The circumferential limiting component (not shown in the figure) engages with the drill rod 811 in a circumferential limiting fit along the borehole. The drill rod drive 817 drives the drill rod 811 to move axially along the borehole via the rotating rod 809. The axial movement of the drill rod 811 is achieved through the threaded engagement of the rotating rod 809 and the circumferential limiting component, allowing the drill rod 811 to move up and down within the borehole.

[0061] Furthermore, the drilling assembly 82 also includes a fixing rod 808; the fixing rod 808 is sleeved on the outside of the rotating rod 809, and the drill rod drive 817 is installed on the upper end of the fixing rod 808. By setting the fixing rod 808, a mounting base can be provided for the drill rod drive 817, while also protecting the rotating rod 809.

[0062] Furthermore, a drill bit 816 is provided at the lower end of the drill rod 811.

[0063] Furthermore, the drilling assembly 82 also includes a rotating block 805; the rotating block 805 is located on the side of the fixed rod 808 and provides an installation base for the fixed rod 808.

[0064] In some embodiments, the geological exploration drilling equipment further includes a moving mechanism 9 and a tilting drive mechanism 10; the base plate 1 of the moving mechanism 9 has a drill groove 3 for the drilling mechanism 8 to pass through; the drilling mechanism 8 and the moving mechanism 9 cooperate in a horizontal direction; the tilting drive mechanism 10 is installed on the moving mechanism 9; the tilting drive mechanism 10 is connected to the drilling mechanism 8 and is used to drive the drilling mechanism 8 to switch between an upright state and a horizontal state in a horizontal direction. By setting the moving mechanism 9, the entire equipment can be moved easily. By setting the tilting drive mechanism 10, the drilling mechanism 8 can be switched from a horizontal state to an upright state when drilling is required. When drilling is not required, the drilling mechanism 8 can be switched from an upright state to a horizontal state, lowering the center of gravity of the equipment and facilitating movement.

[0065] Furthermore, the tilting drive mechanism 10 includes a telescopic cylinder 803; one end of the telescopic cylinder 803 is hinged to the moving mechanism 9 in a horizontal direction, and the other end of the telescopic cylinder 803 is hinged to the drilling mechanism 8 in a horizontal direction. The telescopic cylinder can achieve stable switching of the state of the drilling mechanism 8.

[0066] Furthermore, the tilting drive mechanism 10 also includes a first rotating shaft 802 and a second rotating shaft 807; the lower end of the telescopic cylinder 803 is rotatably engaged with the connecting rod 7 of the second fixed frame via the first rotating shaft 802 in a horizontal direction, and the upper end is rotatably engaged with the rotating block 805 via another first rotating shaft 802 in a horizontal direction. The rotating block 805 is rotatably engaged with the bracket 6 of the second fixed frame via the second rotating shaft 807 in a horizontal direction. When the telescopic cylinder 803 shortens, the rotating block 805 rotates about one side of the first fixed frame 5 with the second rotating shaft 807 as the axis of rotation, and finally falls into the placement slot. When the telescopic cylinder 803 extends, the rotating block 805 rotates away from the first fixed frame 5 until it returns to an upright state.

[0067] Furthermore, the flipping drive mechanism 10 also includes a first fixed seat 801 and a second fixed seat 804; the first fixed seat 801 is disposed on the upper surface of the connecting rod 7, and the second fixed seat 804 is mounted on the side of the rotating block 805; a first rotating shaft 802 is mounted on the first fixed seat 801, and another first rotating shaft 802 is mounted on the second fixed seat 804, and the central axes of the two first rotating shafts 802 are arranged in parallel.

[0068] Furthermore, the moving mechanism 9 includes a first fixed frame 5 and a second fixed frame; the first fixed frame 5 and the second fixed frame are spaced apart on the base plate 1 along its length. The drilling mechanism 8 rotates with the second fixed frame in a horizontal direction, and a placement groove is formed on the upper surface of the first fixed frame 5; when the drilling mechanism 8 is in a horizontal state, the end of the drilling mechanism 8 away from the drill bit 816 is located in the placement groove. By providing the placement groove, the drilling mechanism 8 is prevented from shaking or vibrating when moving, thereby improving its service life.

[0069] Specifically, the second fixed frame includes a bracket 6 and a connecting rod 7; the bracket 6 is rotatably engaged with the rotating block 805 of the drilling mechanism 8 in a horizontal direction. Specifically, the bracket 6 is rotatably engaged with the rotating block 805 via a second rotating shaft 807, and the lower end of the telescopic cylinder is rotatably engaged with the connecting rod 7 via a first rotating shaft 802, while the upper end is rotatably engaged with the rotating block 805 via another first rotating shaft 802. When the telescopic cylinder shortens, the rotating block 805 rotates about one side of the first fixed frame 5 with the second rotating shaft 807 as its rotation axis, eventually falling into the placement slot. When the telescopic cylinder extends, the rotating block 805 rotates away from the first fixed frame 5 until it returns to an upright state.

[0070] Furthermore, the moving mechanism 9 also includes two tracks 2; along the width direction of the base plate 1, the two tracks 2 are spaced apart at the bottom of the base plate 1 and rotate in conjunction with the base plate 1. By setting the tracks 2, the pressure on the ground can be reduced, improving the equipment's ability to traverse soft ground.

[0071] Specifically, the track 2 is symmetrically arranged with respect to the central axis of the base plate 1, and multiple sets of supports 6 are provided. With the arrangement of the track 2, in use, due to the large contact area between the track 2 and the ground, compared with the traditional wheel structure, the track 2 can distribute the weight of the equipment more evenly to the ground, effectively preventing the equipment from sinking into the soft ground, and ensuring that the equipment can travel smoothly on the ground of the goaf and be transferred to the predetermined drilling position.

[0072] Furthermore, the moving mechanism 9 also includes a telescopic support assembly 4; the telescopic support assembly 4 is disposed on the base plate 1 and is used to adjust the height of the moving mechanism 9. By setting the telescopic support assembly 4, not only can the height of the moving mechanism 9 be adjusted, but the stability of the equipment can also be improved.

[0073] Specifically, the telescopic support assembly 4 includes four first support members 41; the four first support members 41 are disposed at four angles on the lower surface of the base plate 1. Each first support member 41 includes a fixed cylinder 404, a cylinder rod 405, and a fixed claw 406; the fixed cylinder 404 is inverted and mounted on the base plate 1, with its drive end passing through the base plate 1 and connected to the cylinder rod 405 located below the base plate 1; the lower end of the cylinder rod 405 is provided with the fixed claw 406. The fixed cylinder 404 drives the fixed claw 406 to move up and down via the cylinder rod 405, thereby adjusting the equipment height.

[0074] Furthermore, a rubber anti-slip pad is provided at the lower end of the fixing claw 406. When the fixing claw 406 contacts the ground, the rubber anti-slip pad can increase the friction, allowing the fixing claw 406 to firmly grip the object and prevent the equipment from shifting due to factors such as vibration and torque during drilling.

[0075] Furthermore, the first support member 41 also includes multiple stabilizing plates 403; multiple stabilizing plates 403 are arranged circumferentially on the fixed cylinder 404. This improves the installation stability of the fixed cylinder 404.

[0076] Specifically, the telescopic support assembly 4 also includes two second support members 42, a fixing block 401, and a baffle 402. The fixing block 401 is located between the first fixing frame 5 and the second fixing frame and is fixedly installed on the base plate 1. The left side of the fixing block 401 is connected to one of the second support members 42, which is horizontally arranged, with the end of the second support member 42 away from the fixing block 401 facing to the left. The right side of the fixing block 401 is connected to another second support member 42, which is horizontally arranged, with the end of the second support member 42 away from the fixing block 401 facing to the right. By setting two horizontally arranged second support members 42, the stability of the equipment can be further improved when the second support members 42 abut against the side wall of the coal mine roadway, making the equipment more stable.

[0077] Preferably, the structure of the second support member 42 is the same as that of the first support member 41.

[0078] Work process:

[0079] The track 2 has a larger contact area with the ground. Compared with the traditional wheel structure, the track 2 can distribute the weight of the equipment more evenly on the ground, effectively preventing the equipment from sinking into soft ground. This ensures that the equipment can travel smoothly on the ground in the goaf and move to the predetermined drilling position. Then, the fixed cylinder 404 is activated. The piston inside the cylinder pushes the cylinder rod 405 downward under the action of air pressure. The fixed claw 406 connected to the cylinder rod 405 descends with the cylinder rod 405. The end of the fixed claw 406 away from the cylinder rod 405 is equipped with a rubber anti-slip pad. When the fixed claw 406 contacts the ground, the rubber anti-slip pad can increase the friction, so that the fixed claw 406 can firmly grip the object and prevent the equipment from shifting due to vibration, torque and other factors during drilling. Finally, the telescopic cylinder 803 is connected to the first fixed seat 801 and the second fixed seat 804 through the first rotating shaft 802. When the telescopic cylinder 803 extends or retracts, due to the first The rotating connection of the shaft 802 can drive the second fixed seat 804 to rotate around the first shaft 802. This causes the rotating block 805 connected to the second fixed seat 804 to change position, realizing the adjustment of the drilling mechanism 8 within a certain angle range. This can adapt to the geological conditions of the goaf area and the drilling requirements in different directions. When the telescopic cylinder 803 is activated to rotate the rotating block 805, the fixed rod 808 plays a role in auxiliary positioning and limiting the rotation range through cooperation with the rotating block 805 and the second shaft 807. When the drill rod drive 817 is activated and drives the rotating rod 809 to rotate, the threaded part of the drill rod 811 will move along the axial direction of the rotating rod 809 due to the transmission action of the thread. This transmission method converts the rotational motion into linear motion, providing power for the drilling of the drill rod 811. During the drilling process of the drill bit 816, the support block 815 is pressed against the inner wall of the borehole by the elastic component 813, which plays a supporting role in the drilling.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
