Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically to a marking device for geological exploration of geological resources in coal mining areas. Background Technology

[0002] Geological exploration of coal mining areas refers to systematic geological work within the mining area, focusing on coal resources while also considering associated resources such as coalbed methane, groundwater, sandstone gas, shale gas, rare elements (such as germanium and gallium), and building materials. This work ranges from regional prediction to local identification. Marking refers to the standardized process of setting up permanent or semi-permanent markers to clearly indicate and permanently identify spatial locations with specific geological or engineering significance during geological exploration fieldwork, and recording and linking related information.

[0003] Chinese invention patent CN120368949B discloses a marking device for geological resource exploration, including a support frame and a lifting mechanism, a hammering mechanism, and a measuring mechanism mounted on the support frame. The lifting mechanism drives the hammering mechanism and the measuring mechanism to move up and down synchronously. A marking mechanism is detachably installed below the hammering mechanism. The hammering mechanism and the measuring mechanism begin working after reaching a preset position. The hammering mechanism is used to hammer the marking mechanism, and the measuring mechanism is used to measure the ground tilt angle. The marking device in this application, with its hammering mechanism, measuring mechanism, and marking mechanism, enables the marking of points and the measurement of tilt angles within a single device during geological exploration, and is adaptable to different soil conditions.

[0004] The marking device in the aforementioned patent requires hammering during use, which is extremely difficult on surfaces such as gravel, coal gangue, or compacted hard soil. It is very easy to drive the marker off-center and damage the pile head. If drilling is used, a series of tasks such as drilling, removing the drill rod, and planting the pile are still required, which is time-consuming and labor-intensive. The device can only provide topographic data for geological exploration during operation. During use, the rock and soil where the marking point is located may experience slight vibrations and tilt changes, which cannot be monitored. It can only indicate the location and cannot provide early warning. Sprayed markings are easily washed away by rainwater, covered by dust, or damaged by subsequent construction, resulting in unclear markings. Summary of the Invention

This invention solves the problems of marking devices requiring hammering during use, which is prone to misalignment and damage to the pile head, is time-consuming and labor-intensive, cannot be used for monitoring, only provides location indication and cannot provide early warning, and sprayed markings are easily washed away by rain, covered by dust or damaged by subsequent construction, resulting in unclear markings.

[0006] The present invention solves the above-mentioned technical problems through the following technical solutions, the present invention comprising: The movable seat has a storage box mounted on its top; A drilling structure, comprising a movable guide rail, a horizontal plate mounted on one side of the slider of the movable guide rail, a drilling motor mounted on the top of the horizontal plate by bolts, and a working plate fixedly mounted on the output shaft of the drilling motor. A marking component is installed at the bottom of the horizontal plate. The marking component is used to directly insert the drill rod as a marking rod into the marking position, and can be combined with different marking methods to meet different marking requirements. The marking assembly includes a positioning seat installed at the bottom of the working plate, an assembly structure installed inside the positioning seat, a marking structure installed at the top of the positioning seat, two sets of positioning blocks respectively installed at the bottom of the marking structure and the bottom of the working plate, and a stake structure installed at the bottom of the positioning seat.

The assembly structure includes an assembly column rotatably installed inside the transmission hole via a transmission column, a bidirectional threaded rod with both ends fixedly welded to one end of the transmission column and rotatably installed on the inner sidewall of the assembly groove, and two threaded rings, a first threaded ring and a second threaded ring, respectively threadedly engaged and sleeved on the bidirectional threaded rod.

[0008] Preferably, the assembly structure further includes two sets of threaded blocks respectively fixedly welded to both sides of the first threaded ring and the second threaded ring, and a limiting post fixedly welded to one side of the threaded block.

[0010] Preferably, a T-shaped pull-out groove is provided on one side of the marking base, and the pull-out component includes a T-shaped block fused to the inner wall of the T-shaped pull-out groove by a return spring and a pull rod fixedly welded to one side of the T-shaped block. A marking chip is installed on the top of the T-shaped block.

[0011] Preferably, the marking base is box-shaped, and a marking surface is provided on the top of the marking base.

[0012] Preferably, the marking base is plate-shaped, and the marking surface is provided on one side of the marking base.

[0013] Preferably, the pile planting structure includes a drill rod fixedly welded to the bottom of the positioning seat, an inlet sleeve fixedly sleeved on the outer side of the top of the drill rod, and a drill bit fixedly welded to the bottom of the drill rod. The bottom of the inlet sleeve is provided with a feed groove, and one side of the feed groove is provided with a feed port.

[0014] Preferably, the drill bit assembly includes a T-shaped post fixedly welded to the bottom end of the drill rod, a conical head fixedly welded to the bottom of the T-shaped post, a sensing module mounted on one side of the T-shaped post, and a protective ring sleeved on the outside of the T-shaped post.

This adapts to different exploration task requirements. The drill rod is directly retained as a marking rod after drilling, eliminating the traditional rod removal and pile planting steps, significantly simplifying the operation process and saving manpower and time costs. Multiple design features ensure the durability and diversity of marking information. The marking surface uses physical marking methods such as engraving and fluorescent spraying to ensure long-term readability in the field. The T-shaped block integrates a marking chip that can store data such as coordinates, geological strata, and exploration date, supporting reading by specialized equipment, achieving digital storage and precise traceability, overcoming the shortcomings of traditional spray-painted markings that are easily damaged by the environment.

[0016] 2. The drill bit integrates a sensing module, which can monitor the vibration and tilt changes of the surrounding rock and soil in real time. The data is fed back to the control center and an early warning is issued when there are abnormalities. This provides dynamic data support for geological disaster prevention and engineering safety assessment, enabling the device to have both static marking and dynamic monitoring functions, thereby improving the safety and intelligence level of exploration work. Through structural optimization and functional integration, this invention realizes the integration of drilling, marking, data storage and monitoring and early warning, effectively improving the efficiency, accuracy and reliability of geological exploration marking work in coal mining areas. It has strong practical value and promotion prospects. Attached Figure Description

[0019] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0020] A marking device for geological exploration of geological resources in coal mining areas, such as Figures 1-8 As shown, it includes a movable base 1, a drilling structure 3, and a marking assembly 4; The top of the mobile base 1 is equipped with a placement box 2, and the placement box 2 contains multiple marking components 4 to facilitate multiple marking operations. The drilling structure 3 includes a movable guide rail 301, a horizontal plate 302 mounted on one side of the slider of the movable guide rail 301, a drilling motor 303 mounted on the top of the horizontal plate 302 by bolts, and a working plate 304 fixedly mounted on the output shaft of the drilling motor 303.

[0021] like Figure 1-8 As shown, the marking component 4 is installed at the bottom of the horizontal plate 302. The marking component 4 is used to directly insert the drill rod as a marking rod into the marking position, and to combine different marking methods with different marking requirements.

[0022] The marking component 4 includes a positioning seat 401 installed at the bottom of the working plate 304, an assembly structure 402 installed inside the positioning seat 401, a marking structure 403 installed at the top of the positioning seat 401, two sets of positioning blocks 404 respectively installed at the bottom of the marking structure 403 and the bottom of the working plate 304, and a stake structure 405 installed at the bottom of the positioning seat 401.

[0023] Furthermore, the top of the positioning seat 401 is provided with a positioning groove 5, one side of the positioning groove 5 is provided with an assembly groove, and one side of the assembly groove is provided with a transmission hole. The assembly structure 402 includes an assembly column 4021 rotatably installed inside the transmission hole via a transmission column, a bidirectional threaded rod 4022 whose two ends are respectively fixedly welded to one end of the transmission column and rotatably installed on the inner side wall of the assembly groove, and two threaded rings 4023 and 4024 respectively threadedly engaged and sleeved on the bidirectional threaded rod 4022.

[0024] Furthermore, the assembly structure 402 also includes two sets of threaded blocks 4025 that are respectively fixedly welded to both sides of the first threaded ring 4023 and the second threaded ring 4024, and a limiting post 4026 fixedly welded to one side of the threaded block 4025. The positioning block 404 cooperates with the positioning groove 5, and a limiting hole 6 is opened on the positioning block 404. The limiting post 4026 cooperates with the limiting hole 6. A cross groove 7 is opened on one side of the assembly post 4021.

[0025] Furthermore, the marking structure 403 includes a positioning plate 4031 fixedly welded to the top of the positioning block 404, a marking seat 4032 installed on the top of the positioning plate 4031, and a pull-out member 4033 installed inside the marking seat 4032.

[0026] Furthermore, a T-shaped pull-out groove is provided on one side of the marking base 4032, and the pull-out component 4033 includes a T-shaped block 9 fused to the inner wall of the T-shaped pull-out groove by a return spring 8 and a pull rod 10 fixedly welded to one side of the T-shaped block 9. A marking chip 11 is installed on the top of the T-shaped block 9.

[0027] Furthermore, the marker base 4032 is box-shaped, and a marking surface 12 is provided on the top of the marker base 4032.

[0028] Furthermore, the marker base 4032 is plate-shaped, and a marking surface 12 is provided on one side of the marker base 4032.

[0029] Different marker holders 4032 are selected according to work requirements, and marking is performed directly through the marking surface 12. The marking chip 11 is specifically a module that records information including QR code / NFC chip. When the information on the marking surface 12 is blurry, the internal chip can be used to ensure the accuracy of marking.

[0030] Furthermore, the pile planting structure 405 includes a drill rod 4051 fixedly welded to the bottom of the positioning seat 401, an inlet sleeve 4052 fixedly sleeved on the outer side of the top of the drill rod 4051, and a drill bit 4053 fixedly welded to the bottom of the drill rod 4051. The bottom of the inlet sleeve 4052 is provided with a feed groove 13, and a feed port 14 is provided on one side of the feed groove 13.

[0031] The feed inlet 14 and feed trough 13 facilitate the disassembly and assembly of drill rod 4051 after drilling. Drill rod 4051 can be used directly as a marker rod. High-strength, fast-setting grouting material, such as cement mortar, epoxy resin or special geological anchoring agent, is injected into the annulus between drill rod 4051 and the borehole wall. The grouting body wraps around the lower half of drill rod 4051 to form an anchor body, providing pull-out resistance far exceeding that of simple friction, which is suitable for loose strata.

[0032] Furthermore, the drill bit component 4053 includes a T-shaped post 15 fixedly welded to the bottom end of the drill rod 4051, a conical head 16 fixedly welded to the bottom of the T-shaped post 15, a sensing module 17 installed on one side of the T-shaped post 15, and a protective ring 18 sleeved on the outside of the T-shaped post 15. Threaded surfaces are provided on the outer top of the T-shaped post 15 and the inner sidewall of the protective ring 18. The protective ring 18 is threaded and sleeved on the outside of the T-shaped post 15. The diameter of the conical head 16 is larger than the diameter of the drill rod 4051.

[0033] The diameter of the conical head 16 is larger than that of the drill rod 4051. After drilling, there is an annular space between the drill rod 4051 and the hole wall. The sensing module 17 during the drilling process is protected by the protective ring 18. After the slurry is filled, the sensing module 17 can be a micro-vibration and tilt sensor to monitor the minute vibrations and tilt changes of the rock and soil where the marker point is located, and is used for slope stability monitoring or early warning of the initial settlement of the goaf.

[0034] Working principle: When in use, the movable seat 1 is moved to the geological exploration point to be marked in the coal mining area, and a set of marking components 4 is taken out through the placement box 2; Align and embed the positioning block 404 at the bottom of the work plate 304 with the positioning groove 5 at the top of the positioning seat 401. Then, use a tool to insert into the cross groove 7 on one side of the assembly column 4021 and rotate it, which will drive the transmission column and the bidirectional threaded rod 4022 to rotate. The first threaded ring 4023 and the second threaded ring 4024 move in opposite directions, and then push the limiting column 4026 into the limiting hole 6 on the positioning block 404 through the threaded block 4025, so as to achieve a stable assembly of the marking component 4 and the work plate 304. Start the drilling motor 303. The output shaft of the drilling motor 303 drives the working plate 304 to rotate. At the same time, the slider of the moving guide rail 301 drives the horizontal plate 302 to move downward. The conical head 16 in the pile planting structure 405 contacts the ground first. Because its diameter is larger than that of the drill rod 4051, it quickly drills into the ground surface under the action of rotational force. The protective ring 18 on the outside of the T-shaped column 15 is threaded and sleeved on the T-shaped column 15. During the drilling process, it effectively protects the sensing module 17, micro-vibration and tilt sensor installed on one side of the T-shaped column 15, and avoids direct impact of rock and soil debris on the sensor. As the drill rod 4051 continues to descend, the guide sleeve 4052 enters the hole in sync. When the hole reaches the preset depth, stop the drilling motor 303, rotate the assembly column 4021 in the opposite direction, so that the limiting column 4026 exits the limiting hole 6 and separates the positioning seat 401 from the working plate 304. High-strength, fast-setting grouting material, such as cement mortar or epoxy resin, is injected into the feed trough 13 through the feed inlet 14 on one side of the feed sleeve 4052. The grouting material flows into the annulus between the drill rod 4051 and the hole wall through the feed trough 13, wrapping the lower half of the drill rod 4051 to form an anchor body. After the grout solidifies, the drill rod 4051 is firmly implanted into the marking position as a marking rod. Select the appropriate marker base 4032 according to the on-site marking requirements. If a box-shaped marker base 4032 is selected, the marking surface 12 on its top can be used to write or paste the marking directly. If a plate-shaped marker base 4032 is selected, the marking can be completed through the marking surface 12 on its side. At the same time, pull the pull rod 10 on one side of the marker base 4032 to drive the T-shaped block 9 to slide out along the T-shaped pull groove against the elastic force of the return spring 8. The marking chip 11, which contains detailed information of the exploration point, such as coordinates, stratigraphic lithology, exploration date, etc., and contains a QR code or NFC chip, is placed on the top of the T-shaped block 9. After releasing the pull rod 10, the return spring 8 drives the T-shaped block 9 and the marking chip 11 to return to the T-shaped pull groove, forming a double marking guarantee and completing the marking operation. During subsequent geological exploration, the sensor module 17 can monitor the minute vibrations and tilt changes of the rock and soil where the marker point is located in real time. If the monitoring data is abnormal, it can perform early warning analysis in a timely manner to ensure the long-term stability and information accuracy of the marker point.

[0035] The above are merely preferred embodiments of the present invention and are illustrative in nature, not restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
