Description

Technical Field

[0001] This invention relates to the field of exploration equipment, and more particularly to a tungsten ore exploration and sampling device. Background Technology

[0002] Currently, most existing tungsten mine exploration drilling rigs are designed with a single vertical downward drilling structure. These rigs are usually anchored to the ground via a fixed base, relying on their own weight and anchoring structure to ensure stability during vertical drilling. They are applicable to conventional vertical exploration operations and have been widely used in various tungsten mine exploration scenarios. However, in the process of underground tungsten mine mining, as mining operations progress, in order to accurately determine the mining direction, track the extension trajectory of concealed ore bodies, and avoid resource waste and safety hazards caused by blind mining, it is often necessary to conduct lateral exploration sampling on the mine sidewalls to obtain geological information of the sidewall rock mass.

[0003] However, since existing drilling rigs are mainly designed for vertical drilling, their fixing structures are adapted for vertical installation on the ground. In the scenario of horizontal exploration on the sidewall of a mine, there is a lack of effective fixing and installation structures, making it impossible to achieve stable fixation of the drilling rig on the sidewall. Some existing exploration drilling rigs that can achieve multi-angle drilling have complex structures, large size, and heavy weight, making them difficult to use in mines. Therefore, the industry currently generally adopts the method of manually picking up and pressing the drilling rig for horizontal exploration and sampling. Operators need to hold the drilling rig close to the sidewall of the mine and rely on manpower to provide the clamping force and stability required for drilling to complete the horizontal drilling and sampling. The manual operation is extremely labor-intensive, and long-term operation can easily lead to muscle strain, hand fatigue, and unstable grip, which can cause safety accidents such as drilling rig slippage and drill rod displacement. Summary of the Invention

[0004] In order to overcome the shortcomings of existing exploration drilling rigs, such as limited functionality and poor adaptability, which make it impossible to meet the needs of vertical sampling and lateral sampling of mine sidewalls in tungsten ore exploration, this invention provides a tungsten ore exploration sampling device.

[0005] The technical solution is as follows: A tungsten ore exploration and sampling device includes a drilling rig; it also includes rotating rods connected to the drilling rig; each rotating rod has a groove; each groove has a slider slidably connected to it; each slider has a rotating shaft fixedly connected to the side facing the drilling rig; each rotating shaft has a connecting block rotatably connected to it; each rotating shaft has several fixing holes; each connecting block has a locking screw rotatably connected to it, and each locking screw is inserted into a corresponding fixing hole; each connecting block is fixedly connected to the drilling rig; a first electric push rod is detachably connected to the drilling rig; a second electric push rod is detachably connected to each rotating rod; a first clamping block is fixedly connected to the output end of each first and second electric push rod; each slider has a handle connected to the side facing away from the drilling rig; each handle has a locking component for locking the slider to the rotating rod.

[0006] As a further preferred embodiment, the locking assembly includes wedge blocks connected to the handle; each wedge block is slidably connected within a corresponding slider, and the handle passes through the slider and is threadedly connected to the slider; each slider is slidably connected with a plurality of symmetrically arranged second clamping blocks; each second clamping block is in contact with a corresponding wedge block; a plurality of springs are fixed between each second clamping block and its corresponding slider; the side of each second clamping block facing away from the wedge block is in contact with the groove wall of the slide, and the contact surface between the second clamping block and the groove wall is set as a rough surface.

[0007] As a further preferred option, each first clamping block is provided with a through hole.

[0008] As a further preferred option, each first clamping block is provided with a rubber pad.

[0009] As a further preferred option, each rotating rod has scale lines on both the left and right sides; each slider has an indicator block fixed to both the left and right sides.

[0010] As a further preferred option, a handle that connects to the drilling rig is also included.

[0011] As a further preferred embodiment, it also includes telescopic curtains connected to the rotating rod; several telescopic curtains are fixedly connected between each slider and the corresponding rotating rod.

[0012] As a further preferred option, the grip and handle are both covered with silicone sleeves.

[0013] As a further preferred embodiment, the first electric push rod is detachably connected to the fixed rod; the second electric push rod is detachably connected to the rotating rod.

[0014] As a further preferred option, an alarm system connected to the drilling rig is also included.

[0015] Compared with the prior art, the present invention has the following advantages: Through the rotation design of the fixed rod and the rotating rod, the exploration equipment is supported in an inverted T-shape inside the mine shaft, realizing vertical drilling and sampling of the exploration equipment and drilling and sampling of the mine shaft sidewall; it solves the problem that existing drilling rigs are mainly designed for vertical drilling, and their fixed structure is adapted to vertical installation on the ground. In the scenario of horizontal exploration on the sidewall of the mine shaft, there is a lack of effective fixed installation structure, which makes it impossible to achieve stable fixation of the drilling rig on the sidewall. There is no need for manual hand-held drilling rig for drilling and sampling operations, which greatly reduces the labor intensity of workers and improves the safety of workers during operation; By fixing the rotating rod vertically and horizontally inside the mine shaft, and then adjusting the slider axially along the rotating rod, precise vertical adjustment and sampling of the drill rod can be achieved. This enables multi-point sampling of the mine shaft sidewall in both the horizontal and vertical directions, ultimately achieving multi-point grid sampling of the mine shaft sidewall. The entire adjustment process is simple to operate and precise in positioning. The sampling position can be quickly switched without disassembling the equipment, which greatly improves the sampling efficiency. Moreover, the sampling process strictly complies with industry standards, ensuring the accuracy and representativeness of the exploration data. When workers adjust the slider using the handle, they can accurately determine the range of slider movement by observing the scale lines. At the same time, by aligning the adjusted indicator block with the corresponding scale line, workers can easily adjust the sliders on both sides to a uniform position, improving the accuracy of the adjustment of the slider and drill rod, and thus improving the accuracy of grid sampling.

Detailed Implementation

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: A tungsten ore exploration sampling device, such as Figures 1-7 As shown, the equipment includes a drilling rig; the drilling rig consists of a control box 1, drill rods 2, fixed rods 3, sliding blocks 4, and chain conveyor belts 5; the control box 1 is equipped with a diesel generator to power the electrical components inside the exploration equipment; a rotary motor is fixedly connected to the lower side of the control box 1; the drill rods 2 are installed at the output end of the rotary motor; fixed rods 3 are connected to both the left and right sides of the control box 1; a chain conveyor belt 5 is installed on each fixed rod 3, and the chain conveyor belt 5 is driven to rotate by the motor; sliding blocks 4 are fixedly connected to both the left and right sides of the control box 1; each sliding block 4 is fixedly connected to the corresponding chain conveyor belt 5, and the chain conveyor belt 5 drives the sliding block 4 and the control box 1 to move axially along the fixed rods 3; It also includes a rotating rod 101, a slider 102, a rotating shaft 103, a connecting block 104, a locking screw 105, a first electric push rod 106, a second electric push rod 107, a first pressing block 108, a handle 109, and a locking assembly; a rotating rod 101 is rotatably connected to each fixed rod 3; a sliding groove 10101 is provided in each rotating rod 101; a slider 102 is slidably connected in each sliding groove 10101; a rotating shaft 103 is fixedly connected to the side of each slider 102 facing the control box 1; a connecting block 104 is rotatably connected to each rotating shaft 103; and two fixing holes 10301 are provided on each rotating shaft 103. Two fixing holes 10301 are vertically opened; each connecting block 104 is rotatably connected with a locking screw 105, and each locking screw 105 is inserted into the corresponding fixing hole 10301; each connecting block 104 is fixedly connected to the control box 1; each fixing rod 3 is threadedly connected with a first electric push rod 106; each rotating rod 101 is threadedly connected with a second electric push rod 107; the output end of each first electric push rod 106 and second electric push rod 107 is bolted with a first clamping block 108; each slider 102 is connected to a handle 109 on the side facing away from the control box 1; each handle 109 is connected with a locking assembly.

[0020] The locking assembly includes a wedge block 201, a second pressing block 202, and a spring 203; a wedge block 201 is fixedly connected to each grip 109; each wedge block 201 is slidably connected within a corresponding slider 102, and the grip 109 passes through the slider 102 and is threadedly connected to the slider 102; two symmetrically arranged second pressing blocks 202 are slidably connected to each slider 102; each second pressing block 202 is in contact with a corresponding wedge block 201; two springs 203 are fixedly connected between each second pressing block 202 and its corresponding slider 102; the side of each second pressing block 202 facing away from the wedge block 201 is in contact with the groove wall of the slide groove 10101, and the contact surface between the second pressing block 202 and the groove wall of the slide groove 10101 is set as a rough surface.

[0021] In the initial state: the locking screw 105 is tightened in one of the fixing holes 10301, the slider 102 is fixedly connected to the connecting block 104, the handle 109 is tightened on the slider 102, the wedge block 201 presses the second clamping block 202 into the slide groove 10101, and the slider 102 is locked on the rotating rod 101; at this time, the exploration and sampling equipment is in the position of... Figure 1As shown: Rotating rod 101, fixed rod 3, and brick rod 2 are parallel to each other. The equipment is small in size, making it easy for workers to move and transfer it inside the mine. During underground mining operations, when drilling to take samples perpendicular to the ground is required, the worker first loosens the locking screw 105, and then, using a right-to-left view as a reference, rotates the two rotating rods 101 and their connecting parts counterclockwise by 90°, aligning the locking screw 105 with another fixing hole 10301 on the rotating shaft 103. Then, the worker tightens the locking screw 105 into the other fixing hole 10301. Then, the workers placed the exploration equipment horizontally inside the mine shaft, with the second electric push rods 107 at both ends of the rotating rod 101 facing the left and right sides of the mine shaft. Next, the control box 1 activated the second electric push rods 107 to extend, pushing the corresponding first clamping blocks 108 towards the left and right sides of the mine shaft until the first clamping blocks 108 were pressed tightly against the left or right side of the mine shaft. Then, the workers activated the first electric push rod 106 to push the corresponding first clamping blocks 108 towards the ground, thus pressing the first clamping blocks 108 on the first electric push rod 106 tightly against the ground. Figure 2 As shown: The exploration equipment is placed in a T-shape inside the mine shaft. The worker then starts the rotating motor on control box 1 to rotate the drill rod 2, simultaneously controlling the chain conveyor belt 5 to move the sliding block 4 and drill rod 2 downwards, achieving drilling and sampling operations perpendicular to the ground. When drilling and sampling is required on the sidewall, the worker simply places the exploration equipment vertically inside the mine shaft, with the second electric push rods 107 at both ends of the rotating rod 101 facing the upper and lower sides of the mine shaft. The second electric push rods 107 are then activated to press the first clamping block 108 tightly against the upper and lower sides of the mine shaft. Then, the first electric push rod 106 is activated to push the corresponding first clamping block 108 towards the sidewall of the mine shaft, pressing the first clamping block 108 on the first electric push rod 106 tightly against the sidewall of the mine shaft, thus achieving drilling and sampling operations perpendicular to the ground. Figure 3 As shown: The exploration equipment is placed inside the mine shaft in an inverted T-shape. Then, the worker can start the rotating motor on the control box 1 to drive the drill rod 2 to rotate. At the same time, the chain conveyor belt 5 is controlled to move the sliding block 4 and the drill rod 2 towards the side wall to perform side wall drilling and sampling. This method solves the problem that existing drilling rigs are mainly designed for vertical drilling, and their fixing structure is adapted to vertical installation on the ground. In the scenario of horizontal exploration on the side wall of the mine shaft, there is a lack of an effective fixing and installation structure, which makes it impossible to achieve stable fixing of the drilling rig on the side wall. There is no need for manual hand-held drilling rigs for drilling and sampling operations, which greatly reduces the labor intensity of workers and improves the safety of workers during operation.

[0022] Furthermore, considering that there are clear national / industry standards and sampling methods for sidewall drilling sampling in mines, such as DZ / T0429—2023 "Sampling Specification for Solid Mineral Exploration" and AQ2004—2005 "Safety Regulations for Geological Exploration," these regulations clearly state the need for multi-point sampling to avoid uneven sampling. The most common method is multi-point grid sampling: one borehole every 1-2 meters along the strike and one point every 0.5-1 meters along the vein direction. Therefore, when drilling and sampling the sidewalls of a mine, the worker can move the handle 109 towards the corresponding slider 102. The outer side is loosened, which in turn moves the wedge block 201 away from the connecting block 104, releasing the compression limit on the second clamping block 202. Then, the spring 203 will drive the second clamping block 202 to move towards the slider 102. After that, the second clamping block 202 separates from the inner wall of the slide groove 10101, releasing the lock between the slider 102 and the rotating rod 101. Then, the worker can hold the two handles 109 to drive the slider 102 to slide and adjust within the slide groove 10101, thereby driving the rotating shaft 103, connecting block 104, fixing rod 3, control box 1, and drill rod 2 to move along the rotating rod 101. Axial adjustment: After adjusting the drill rod 2 to the corresponding position according to sampling regulations and methods, the worker tightens the handle 109, causing the wedge block 201 to move towards the connecting block 104. This, in turn, presses the second clamping block 202 into the slide groove 10101 via the wedge block 201, locking the slider 102 back onto the rotating rod 101. This allows for re-sampling. Based on this adjustment structure, when performing grid sampling on the mine sidewall, the worker only needs to first vertically inwardly fix the rotating rod 101 inside the mine. Then, by adjusting the position of the slider 102, the drill rod 2 can be moved along the rotating rod 10104. 1. The drill rod 2 is adjusted vertically along the axis to complete multi-point sampling in the vertical direction of the sidewall. After the vertical multi-point sampling is completed, the worker fixes the rotating rod 101 horizontally inside the mine shaft. Then, the drill rod 2 can be adjusted horizontally along the axis of the rotating rod 101 to complete multi-point sampling in the horizontal direction of the sidewall. Finally, the multi-point grid sampling operation of the mine shaft sidewall is realized. The entire adjustment process is simple to operate and precise in positioning. The sampling position can be quickly switched without disassembling the equipment, which greatly improves the sampling efficiency. Moreover, the sampling process strictly complies with the industry standard requirements, ensuring the accuracy and representativeness of the exploration data.

[0023] In a further preferred embodiment of the present invention, such as Figures 1-3 As shown, each first clamping block 108 has a through hole 10801.

[0024] In this embodiment, considering that the tungsten ore strata are relatively hard, the drill rod 2 will generate a large vibration during the drilling and sampling process, which will cause the equipment to vibrate. Therefore, in order to improve the overall stability of the equipment, after the workers fix the internal support of the equipment in the mine, they can pass the fixing screw through the through hole 10801 and drill it into the mine wall, thereby locking the first clamping block 108 into the mine wall and improving the overall stability of the equipment.

[0025] In a further preferred embodiment of the present invention, such as Figures 1-3 As shown, each first clamping block 108 is provided with a rubber pad 10802.

[0026] In this embodiment, the rubber pad 10802 provided on the contact surface between the first pressing block 108 and the mine wall improves the adhesion and pressing effect between the first pressing block 108 and the rock wall.

[0027] In a further preferred embodiment of the present invention, such as Figure 4 and Figure 5 As shown, each rotating rod 101 has scale lines 10102 on both the left and right sides; each slider 102 has an indicator block 10201 fixedly connected to both the left and right sides.

[0028] In this embodiment, when the worker adjusts the slider 102 using the handle 109, the range of movement of the slider 102 can be accurately determined by observing the scale line 10102. At the same time, by aligning the adjusted indicator block 10201 with the corresponding scale line 10102, the worker can easily adjust the sliders 102 on both sides to a uniform position, thereby improving the worker's precision in adjusting the slider 102 and the drill rod 2, and thus improving the accuracy of grid sampling.

[0029] In a further preferred embodiment of the present invention, such as Figure 1 As shown, it also includes a handle 204; the handle 204 is fixedly attached to both fixed rods 3.

[0030] In this embodiment, the worker can simultaneously rotate the handle 204 to adjust the two connecting blocks 104, which makes it convenient for the worker to rotate and adjust the fixing rod 3 and the drill rod 2.

[0031] In a further preferred embodiment of the present invention, such as Figure 4 and Figure 5 As shown, it also includes telescopic curtains 205; each slider 102 is fixedly connected to four vertically symmetrical telescopic curtains 205 between itself and the corresponding rotating rod 101.

[0032] In this embodiment, the slide 10101 is sealed by the telescopic curtain 205 to prevent external impurities from entering the slide 10101 and affecting the sliding adjustment of the slider 102, thus adapting to the harsh environment of the mine.

[0033] In a further preferred embodiment of the present invention, both the grip 109 and the handle 204 are provided with silicone sleeves on their outer surfaces.

[0034] In this embodiment, the silicone sleeve is soft and has a high coefficient of friction, which can improve grip and anti-slip performance in the harsh working conditions of damp and dusty mines, and prevent the hand from slipping and falling. At the same time, it can buffer the vibration of the equipment to the hand, reduce fatigue damage caused by long-term operation, and further optimize the grip comfort and operation safety of handling, adjustment and locking operations.

[0035] In a further preferred embodiment of the present invention, the first electric push rod 106 is detachably connected to the fixed rod 3; the second electric push rod 107 is detachably connected to the rotating rod 101.

[0036] In this embodiment, when workers move or transfer the exploration equipment, they can remove the first electric push rod 106 and the second electric push rod 107 from the fixed rod 3 and the rotating rod 101 to reduce the weight and volume of the equipment, making it easier for workers to move or transfer the exploration equipment in the narrow space of the mine.

[0037] Example 2: Based on Example 1, such as Figure 1 As shown, it also includes an alarm 206; the alarm 206 is fixedly connected to the control box 1.

[0038] In this embodiment, when drilling for sampling, the worker can set the drilling depth of the drill rod 2 through the controller. When the chain conveyor belt 5 drives the drill rod 2 to drill to the set depth, the alarm 206 will sound an alarm to remind the surrounding workers that the drilling for sampling has been completed. The workers do not need to check the drilling for sampling progress at all times.

[0039] The technical principles of the embodiments of the present invention have been described above with reference to specific examples. These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the embodiments of the present invention.
