Description

Technical Field

[0001] The invention relates to the technical field of mineral exploration, and in particular to a mineral resource exploration drilling device. Background Art

[0002] Mineral resource exploration drilling is a key technology in earth science and mining engineering. Its role is to explore and evaluate the existence, nature and scale of underground mineral deposits and provide a scientific basis for mineral development. Specifically, the main functions of mineral resource exploration drilling include:

[0003] Confirm the location and characteristics of the ore body: Through drilling, it is easy to intuitively understand the stratigraphic structure, rock type and ore content, and verify the geological model prediction. It can determine the grade and reserves of the ore deposit, analyze the chemical composition of the samples, estimate the quality and commercial value of the mineral, guide the formulation of subsequent mining plans, evaluate the environmental sensitivity of the mining area, such as the possibility of groundwater pollution, and promote green mining practices. In particular, it can intuitively reveal geological conditions, deeply understand the characteristics of the strata, such as permeability and stability, avoid construction risks, and optimize mine design. For some geological disasters that may be associated with mining activities, such as collapse and landslides, countermeasures can be taken through pre-detection. Only by conducting detailed mineral exploration and evaluation before investment can it help the government and enterprises make rational judgments and balance the cost-benefit ratio.

[0004] In the prior art, mineral resource exploration drilling is often carried out directly at the selected exploration point, that is, after drilling multiple sites in multiple areas one by one, the exploration situation is summarized. However, a problem that often occurs in practice is that when the first few sites in the target area are explored, regardless of the specific resource distribution, the geological structure is stable and meets the mining conditions. However, when exploring the subsequent sites, it may be found that there are underground cavities at a certain depth in the current drilling site, such as karst caves, underground rivers, or loose geological layers with extremely unstable structures. Some of these special geological structures not only pose great risks during mining, but are even impossible to mine, or the cost of mining to avoid the corresponding geological risks has exceeded the economic benefits brought by mining. It is obviously unnecessary to conduct exploration and analysis of the next site, or there is even the possibility of collapse during exploration drilling, then the holes drilled previously will become waste holes, wasting manpower and material resources. In addition, in existing drilling equipment, the connection between the drill rod and the drill bit may occasionally become loose during installation, causing slipping during drilling at the very least, or the drill bit to fall off at the worst. However, it is difficult to detect this in time during the drilling process, which also brings unnecessary trouble to the exploration and drilling work. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a mineral resource exploration drilling equipment to solve the above-mentioned problems raised in the background technology.

[0006] The present invention is achieved through the following technical solutions:

[0007] A mineral resource exploration drilling equipment includes a drill rod and a driving mechanism for driving the drill rod to rotate. A sensor element is provided at the connection between the bottom end of the drill rod and the drill bit. The sensor element is used to detect whether the drill rod and the drill bit rotate synchronously. When one of the sensor elements detects that the drill rod and the drill bit are out of synchronous rotation, the driving mechanism stops immediately.

[0008] Furthermore, the drill rod and the drill bit are socket-matched, and the plug-in section of the drill rod is coaxially inserted into the socket section of the drill bit, and the plug-in section includes a cylindrical section coaxial with the drill rod and a fan-shaped protrusion concentrically arranged on the outer wall of the cylindrical section; the inner wall of the socket hole in the socket section has a fan-shaped inner expansion groove for rotatably mounting the fan-shaped protrusion, one side of the fan-shaped protrusion is in contact with one side wall of the fan-shaped inner expansion groove, and the other side of the fan-shaped protrusion is connected to the other side wall of the fan-shaped inner expansion groove through an elastic member, and the elastic member is in contact with a pressure sensor.

[0009] Furthermore, the elastic member is an arc-shaped coil spring extending along the circumferential direction of the fan-shaped inner expansion groove, and a curved bolt-shaped plug is built into one end of the arc-shaped coil spring, and one end of the plug head is in contact with one end of the arc-shaped coil spring, and the other end is in contact with the other side of the fan-shaped protrusion; the pressure sensor is a circular ring structure, or is in contact with the other section of the arc-shaped coil spring through a support sleeve, and the bolt column of the plug is coaxially and non-contactly inserted into the pressure sensor or the support sleeve.

[0010] Furthermore, a guide rod is fixed to the other side of the fan-shaped inner expansion groove, the bending direction of the guide rod is consistent with the circumferential direction of the fan-shaped inner expansion groove, and the guide rod is always in sliding contact with the axial hole of the bolt body.

[0011] Specifically, the driving mechanism in the present invention includes a central gear plate that is transmission-connected to the driving device, and a plurality of transmission gears are arranged in a circular array around the central gear plate. When the central gear plate rotates, all the transmission gears drill synchronously.

[0012] Furthermore, a fan-shaped balancing cavity is provided on the inner side wall of the socket; when the fan-shaped protrusion is in rigid contact with the other side wall of the fan-shaped inner expansion groove, the fan-shaped protrusion and one side wall of the fan-shaped inner expansion groove form a fan-shaped cavity; the size of the fan-shaped balancing cavity can maintain dynamic balance when the drill rod and the drill bit are in rigid contact and rotate synchronously. The fan-shaped balancing cavity and the fan-shaped cavity are centrally symmetrical with the center of the drill rod.

[0013] Furthermore, the plug-in section has a blind hole inside, and two drainage holes are respectively provided on the side walls of the bottom of the blind hole. The two drainage holes are respectively used to inject oil into the fan-shaped balancing chamber and the fan-shaped cavity, and a pressure plate is also provided above the oil in the blind hole. The pressure plate is pressed downward by a push spring installed in the blind hole and always keeps in contact with the oil surface. A distance sensor is provided above the pressure plate, and the distance sensor is used to detect the position of the pressure plate. When the distance sensor detects that the distance between the pressure plate and it is not within the set range, the drive mechanism stops immediately.

[0014] Furthermore, a mounting rod is fixed above the oil level of the blind hole, a guide column is fixed downward at the center of the mounting rod, the guide column is axially slidably connected to the pressure plate, and the push spring is coaxially sleeved on the guide column between the pressure plate and the mounting rod.

[0015] Furthermore, the end face of the socket section has an annular groove, and a sealing ring is fixed on the stop end face of the plug section, and the sealing ring is embedded in the annular groove.

[0016] Furthermore, the present invention also includes a frame, which includes a disc-shaped main shell, and sub-shells arranged in an annular array around the main shell, the sub-shells are integrally formed with the main shell, and the center of each sub-shell is connected to the center of the main shell through a reinforcing rib beam; the central gear plate is rotatably installed in the main shell, the transmission gear is rotatably installed in the sub-shell, and the center of the main shell has a flange connection end fixedly connected to the reducer or the power motor, and the output shafts of the reducer or the power motor are respectively connected to the central gear plate through the flange connection end.

[0017] The beneficial effect of the present invention is that the mineral resource exploration drilling equipment of the present invention can perform multi-point synchronous drilling in a relatively larger area by using multiple drill rods to drill multiple sites synchronously. While ensuring the drilling efficiency as much as possible, when one of the drill rods encounters a cave, a river channel, or a loose geological layer underground in the exploration area, it will automatically stop, which is convenient for the surveyor to choose whether to continue drilling, and avoid the traditional multiple individual drillings, and then find that there are special geological layers such as caves and underground rivers in the area that are difficult or cannot be conventionally mined when drilling to a certain place. It avoids the original drilled hole from becoming a waste hole, and timely discovers the geological hazards faced by mineral mining, so that the surveyor and the mining party can judge the economic and safety of mining as soon as possible. In addition, since the sensor element is used in the present invention to detect the reliability of the transmission connection between the drill bit and the drill rod, it can be timely found whether the drill bit is operating normally, and the adverse consequences that may be caused when the two rotate relative to each other can be avoided.

[0018] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] See also Figure 1 and Figure 3 The present invention provides a technical solution: a mineral resource exploration drilling equipment, which mainly includes a drill rod 27 and a driving mechanism for driving the drill rod 27 to rotate. A sensor element is provided at the connection between the bottom end of the drill rod 27 and the drill bit. The sensor element here is used to detect whether the drill rod 27 and the drill bit rotate synchronously, or specifically, for example, to detect whether the drill rod 27 and the drill bit rotate as a whole by rigid transmission. In practice, the driving mechanism is mainly any optional equipment that can drive the drill rod 27 to drill. It can be driven independently or in linkage. For example, when driven independently, the drill rods 27 can be distributed far apart to form a decentralized arrangement in a larger area. For large-area fixed-point surveys, all drilling rigs can be started synchronously. For surveys of small-scale key set areas, a linkage design can also be used. For example, Figure 1 The driving mechanism includes a central gear plate 1 which is connected to the driving device in a transmission manner, and a plurality of transmission gears 2 are arranged in a circular array around the central gear plate 1. When the central gear plate 1 rotates, all the transmission gears 2 drill synchronously, so as to conduct multi-point simultaneous exploration in the current exploration area. Moreover, during the exploration drilling process, if one of the sensor elements detects that the corresponding drill rod 27 is out of synchronous rotation with the drill bit, the driving mechanism will be immediately stopped, and the corresponding speed sensor can be set for comparison. In more detail, when drilling below the set depth, if one of the sensor elements detects that the corresponding drill rod 27 is out of synchronous rotation with the drill bit, or is out of the rigid transmission connection relationship, the drilling will be stopped so that other methods can be used to explore the area later, or the drilling can be independently carried out at the drill rod 27 where the current sensor assembly is located, so as to determine the internal geological conditions of the current drilling position point, and avoid the risk of collapse of underground holes or soft geological layers during drilling as soon as possible, and the current exploration point may not have ordinary mining conditions and needs special exploration.

[0032] In this embodiment, for the sensor element, if a speed sensor is used for monitoring and comparison, the design of the drilling element formed by the drill rod and the drill bit may be more complicated and more difficult to modify. Therefore, this embodiment introduces the following structure for design: Figure 2-Figure 3 As shown, the drill rod 27 used is in a socket-and-socket fit with the drill bit, and the plug section 3 of the drill rod 27 is coaxially inserted into the socket section 4 of the drill bit. The structures of the drill rod 27 and the rest of the drill bit can be adaptively designed or directly use the drill rod 27 or drill bit on the market. Specifically, the plug section 3 includes a cylindrical section coaxial with the drill rod 27, and a fan-shaped protrusion 5 concentrically arranged on the outer wall of the cylindrical section. At the same time, a fan-shaped inner expansion groove 6 is processed on the inner wall of the socket hole in the socket section 4 for the fan-shaped protrusion 5 to be rotatably installed around the center of the drill rod 27, as shown in FIG. Figure 2 One side of the fan-shaped protrusion 5 is in contact with one side wall of the fan-shaped inner expansion groove 6, and the other side of the fan-shaped protrusion 5 needs to be connected with the other side wall of the fan-shaped inner expansion groove 6 through an elastic member to form an elastic connection in the assembled state. At the same time, the elastic member is in contact with a pressure sensor 9, and the deformation of the elastic member is then intuitively reflected on the pressure sensor 9. The position state of the above-mentioned fan-shaped protrusion 5 in the fan-shaped inner expansion groove 6 is reflected by the deformation of the elastic member. When in the assembled state, the pressure sensor 9 detects a fixed value, or an initial value within a range. At this value, the surface drill rod 27 and the drill bit are installed in place, and when drilling, When the drill bit comes into contact with the rock formation, the plug-in section 3 will rotate relatively in the socket section 4 of the drill bit until the other side of the fan-shaped protrusion 5 is in contact with the other side wall of the fan-shaped inner expansion groove 6. At this time, the elastic element is compressed to the maximum stroke, and the initial elastic connection between the plug-in section 3 and the socket section 4 is changed to a rigid connection, thereby forming a rigid transmission connection between the drill rod 27 and the drill bit, that is, the drill rod 27 and the drill bit are integrated and rotate synchronously. Therefore, as long as the pressure value detected by the pressure sensor 9 is a rated working value, it means that the drill rod 27 and the drill bit always maintain a rigid transmission connection, and the two form an integral drilling element, and the drill rod 27 corresponding to each drilling point will rotate at the same speed. During the drilling process, if a cavity is encountered somewhere underground, such as a karst cave, an underground river, or extremely loose rock and soil or even a mud layer, the drill bit will be reversed and reset relative to the plug-in section 3 of the drill rod 27 under the resetting action of the elastic element, and the elastic connection state will be restored. At this time, the detection value of the pressure sensor 9 will change accordingly, and then intuitively reflect the current geological conditions encountered by the drill bit, so that the surveyors can decide whether to stop in time, and remind the drillers that the current underground exploration area may have the above-mentioned special dangerous geological structures, or there may be no possibility of minerals.

[0033] In the above embodiments, more specifically, Figure 2 and Figure 4As shown, the elastic member used is an arc-shaped coil spring 8 extending along the circumferential direction of the fan-shaped inner expansion groove 6, and a curved bolt-shaped plug 7 is built into one end of the arc-shaped coil spring 8. One end of the bolt head 701 of the plug 7 is in contact with one end of the arc-shaped coil spring 8, and the other end is in contact with the other side of the fan-shaped protrusion 5 to achieve elastic connection in the assembled state or in the non-working state. During manufacturing, the pressure sensor 9 is a circular ring structure, or is in contact with another section of the arc-shaped coil spring 8 through an annular support sleeve, so there is no need to impose special restrictions on the structure of the pressure sensor 9. The pressure sensor 9 is installed in a suitable place in the drill rod 27 so that it can contact the support sleeve, and then transmit force to the arc-shaped coil spring 8 through the support sleeve. In order to make the arc-shaped coil spring 8 play a better elastic role, the bolt 702 of the plug 7 is coaxially and non-contactly inserted into the pressure sensor 9 or the support sleeve, and then when the bolt 702 contacts the side wall of the fan-shaped inner expansion groove 6, a rigid transmission is formed to prevent the arc-shaped coil spring 8 from being crushed. In practice, a guide rod 10 can also be fixed on the other side of the fan-shaped inner expansion groove. The bending direction of this guide rod 10 needs to be consistent with the circumferential direction of the fan-shaped inner expansion groove 6, and the guide rod 10 is always in sliding contact with a similarly curved shaft hole 11 of the bolt body, so as to better guide the plug 7 and the arc-shaped coil spring 8 to move along the arc path.

[0034] Since there is a cavity structure in the integral structure formed by the drill rod 27 and the drill bit, the drilling element formed by the entire drill rod 27 and the drill barrel may have a rotational imbalance problem. In order to solve this problem, in this embodiment, as shown in FIG. Figure 2 and Figure 5 As shown, a fan-shaped balancing cavity 12 is specially provided on the inner side wall of the socket. During use, when the fan-shaped protrusion 5 mentioned above is in rigid contact with the other side wall of the fan-shaped inner expansion groove 6, the fan-shaped protrusion 5 and one side wall of the fan-shaped inner expansion groove 6 form a fan-shaped cavity 13. The existence of this fan-shaped cavity 13 may make the above-mentioned drilling element obviously unable to achieve dynamic balance, interfering with drilling. Therefore, the above-mentioned fan-shaped balancing cavity 12 is designed for balancing. The size of this fan-shaped balancing cavity 12 can make the drill rod 27 and the drill bit rigidly contact and rotate synchronously (that is, when the above-mentioned fan-shaped cavity 13 is formed). , maintain dynamic balance; in actual application, it is best that the fan-shaped balancing chamber 12 not only considers the offset of the dynamic balance of the above-mentioned fan-shaped cavity 13, but also considers the unbalanced amount of the free space of the fan-shaped inner expansion groove 6 where the arc-shaped coil spring 8 is located. When the unbalanced amount of the free space of the fan-shaped inner expansion groove 6 where the arc-shaped coil spring 8 is located is not considered, the fan-shaped balancing chamber 12 and the fan-shaped cavity 13 can be simply symmetrical with the center of the drill rod 27, because after all, the unbalanced amount caused by that part of the space is extremely small.

[0035] In this embodiment, in addition to using the pressure value of the pressure sensor 9 for real-time display, the following structural designs can also be selected alone or in combination: Figure 6-Figure 7 As shown, there is a blind hole 14 inside the plug-in section 3. In practice, if it is necessary to use a hollow drill rod 27 or a drill bit at this section, a section of round pipe can be adaptively coaxially fixed in this blind hole 14. Two drainage holes 15 are respectively provided at the side wall of the bottom of the blind hole 14 mentioned above. The two drainage holes 15 are used to inject oil into the fan-shaped balance chamber 12 and the fan-shaped cavity 13 at the appropriate time. In addition, a pressure plate 16 is also provided above the oil in the blind hole 14. The pressure plate 16 is installed by a push spring 18 in the blind hole 14, and is always pressed downward. Then, the pressure plate 16 can always keep in contact with the oil surface, that is, move with the liquid surface. In addition, a distance sensor 19 is required to be provided above the pressure plate 16. This distance sensor 19 detects the distance between the pressure plate 16 and the pressure plate 16, which is actually used to detect the position of the pressure plate 16. When the distance sensor 19 detects that the distance between the pressure plate 16 and the pressure plate 16 is not within the set range, the drive device stops immediately. In this embodiment, the pressing plate 16 is in the set range, or has a set spacing with the distance sensor 19, which means that under normal circumstances, the drill bit and the drill rod 27 are rigidly connected, then the fan-shaped cavity 13 and the fan-shaped balance cavity 12 will be filled with the oil in the blind hole 14, and then the oil in the blind hole 14 will drop to the set height, that is, the pressing plate 16 moves down to the set position, and the detection value of the distance sensor 19 at this set position is equal to a set detection value, which can determine that the drill rod 27 is rigidly connected to the drill bit at this time. If a hollow structure such as an underground cave is encountered, because the drill bit is relatively reversed under the action of the arc coil spring 8 and restores the elastic connection in the initial state or the assembled state, the fan-shaped cavity 13 will inevitably not exist or is not the size during normal drilling, then the oil drop height will not be within the set range, then the pressing plate 16 will not be at the set height position accordingly, but will be set up, then the spacing value detected by the distance sensor 19 will be smaller.

[0036] In this embodiment, based on the above structure, Figure 7 A mounting rod 20 is fixed above the oil level of the blind hole 14, and a guide column 17 is fixed downward in the center of the mounting rod 20. The guide column 17 is connected to the pressure plate 16 in an axially sliding manner to guide the pressure plate 16 to move up and down accurately. A push spring 18 is coaxially sleeved on the guide column 17 between the pressure plate 16 and the mounting rod 20. Relying on the force of the push spring 18, the pressure plate 16 always changes with the change of the oil level.

[0037] In order to achieve a sealing relationship at the connection between the drill rod 27 and the drill bit, as shown in FIG. Figure 3As shown, an annular groove 22 may be provided on the end face of the socket section 4 , and a sealing ring 21 may be fixed on the stop end face of the plug section 3 , and the sealing ring 21 may be embedded in the annular groove 22 .

[0038] Finally, as a more practical design structure, the above gears are installed in the frame, such as Figure 8 This frame includes a disc-shaped main housing 23 and sub-housings 24 arranged in an annular array around the main housing 23. During manufacturing, the sub-housings 24 can be integrally formed with the main housing 23, and the center of each sub-housing 24 is connected to the center of the main housing 23 through a reinforcing rib beam 25, and can be integrally cast. During installation, the central gear plate 1 is rotatably installed in the center of the main housing 23, and each transmission gear 2 is rotatably installed in the corresponding sub-housing 24. In order to be installed and connected with the driving element, the center of the main housing 23 has a flange connection end 26 fixedly connected to the reducer or the power motor. The output shafts of the reducer or the power motor coaxially pass through the flange connection end 26 and are connected to the central gear plate 1 for transmission, and then input torque.
