Description

Technical Field

[0001] The utility model relates to the technical field of coal mine exploration, and more specifically to a coal mine geological deep layer sampling device. Background Art

[0002] The coal mine geological deep sampling device is a device specially used to obtain geological samples from deeper underground parts of coal mines. The portable drill rig for mining is a drilling equipment suitable for mining environments. It is easy to carry and flexible to operate. It can play an important role in mining exploration, sampling and related engineering construction. The overall design is compact and relatively light. It can usually be easily disassembled and assembled. For example, the main driving parts of some portable drill rigs, such as power heads, drill rods, tripods, etc., are light enough to be carried by one or two people, making it easy to move and transport in complex terrain in mines, such as in mountain mines or between different work points in underground tunnels.

[0003] Traditional portable drilling rigs are mainly placed directly on the ground through a tripod or a simple bracket. During the drilling process, especially when the drill bit begins to contact and cut into hard rock or harder geological layers, the drilling rig is prone to shaking due to the reaction force. For example, when using a larger torque and drilling pressure for deep drilling, this shaking will be more obvious, which will not only affect the verticality of the borehole and cause the drilled hole to tilt, but also may cause the drill rod to bend, reducing the service life of the drill rod and may even cause the drill rod to break. In order to avoid this situation, multiple construction workers are often required to be responsible for stabilizing the equipment, which undoubtedly increases the manpower input and also increases the probability of work-related accidents.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0021] Figure 1-Figure 5 It is the best embodiment of the utility model, and the following Figure 1-Figure 5 The utility model is further described.

[0022] Specifically, the coal mine geological deep sampling device includes a vertical pole 1 and a drilling equipment body 2 slidably connected to the vertical pole 1, a connecting plate 4 is fixedly connected to the bottom of the vertical pole 1, and both ends of the connecting plate 4 are fixedly connected to a support frame 3, a sealing groove 5 is provided inside the connecting plate 4, and a sealing plate 6 is sealingly and slidably connected inside the sealing groove 5, a connecting block 7 is fixedly connected at the top center of the sealing plate 6, and a top plate 8 is fixedly connected to the top of the connecting block 7, and a positioning device 9 is installed inside the support frame 3, and the positioning device 9 includes a sealing cavity 91 provided inside the support frame 3, and the internal top end of the sealing cavity 91 is connected to the internal bottom end of the sealing groove 5, and the internal sealing cavity 91 is sealingly and slidably connected to a sealing block 92, and the internal center of the sealing block 92 is fixedly connected to a first bearing 93, and the inner ring of the first bearing 93 is fixedly connected to a rotating rod 9 4. A spiral drill bit 98 is fixedly connected to the bottom of the rotating rod 94, and a second bearing 95 is fixedly installed inside the two support frames 3. The inner ring of the second bearing 95 is fixedly connected to a limiting cylinder 96. The rotating rod 94 is slidably connected in the limiting cylinder 96, and the spiral drill bit 98 passes through the limiting cylinder 96. The outer surface of the limiting cylinder 96 is fixedly connected to a driven bevel gear 97. The surface of the driving bevel gear 14 is meshedly connected to the surface of the driven bevel gear 97. A driving motor 10 is fixedly installed at the inner center of the connecting plate 4. The output end of the driving motor 10 is fixedly connected to an active bevel gear 11. The surface of the active bevel gear 11 is meshedly connected to a transition bevel gear 12. The interior of the transition bevel gear 12 is fixedly connected to a rotating shaft 13. Both ends of the rotating shaft 13 are fixedly connected to the driving bevel gear 14. The interior of the sealing groove 5 is fixedly connected to an elastic block 15.

[0023] In this embodiment, by setting a positioning device 9 and starting the driving motor 10, the spiral drill bit 98 can be driven to rotate at high speed, and by stepping on the top plate 8, the support frame 3 can be stabilized while the spiral drill bit 98 can slowly drill into the ground, and the upright pole 1 can be quickly fixed, thereby improving the stability of the drilling equipment body 2 during operation. Compared with traditional portable drilling rigs, when the spiral drill bit 98 contacts and cuts into the hard geological layer, it can effectively reduce the shaking of the equipment caused by the reaction force, thereby ensuring the verticality of the borehole, and the hole drilled by the equipment is straighter, avoiding subsequent problems that may be caused by the tilt of the hole.

[0024] Specifically, the rotating rod 94 is hexagonal, and a slide groove matching the rotating rod 94 is opened inside the limiting cylinder 96. The outer surface of the rotating rod 94 is slidably connected inside the slide groove, and the limiting cylinder 96 is rotatably connected to the inside of the support frame 3 through the second bearing 95.

[0025] In this embodiment, since a slide groove matching the rotating rod 94 is provided inside the limiting cylinder 96 , when the limiting cylinder 96 rotates, the rotating rod 94 can be driven to rotate without affecting the longitudinal sliding of the rotating rod 94 inside the limiting cylinder 96 .

[0026] Specifically, the top of the elastic block 15 abuts against the bottom of the sealing plate 6 , and the sealing plate 6 slides upward due to the elasticity of the elastic block 15 under normal conditions.

[0027] In this embodiment, by providing an elastic block 15, when the spiral drill bit 98 rotates in the opposite direction and leaves the ground, it can automatically retract into the interior of the support frame 3, thereby preventing the spiral drill bit 98 from scratching the ground when the entire equipment is moving, thereby extending the service life of the spiral drill bit 98.

[0028] Specifically, the end of the spiral drill bit 98 extends to the bottom of the support frame 3 , and the driving bevel gear 14 and the driven bevel gear 97 are both rotatably connected to the inside of the support frame 3 .

[0029] In this embodiment, the spiral drill bit 98 can be driven to rotate by the meshing transmission of the driving bevel gear 14 and the driven bevel gear 97 .

[0030] Specifically, the inner top end of the sealing cavity 91 is communicated with the inner bottom end of the sealing groove 5 , and the outer surface of the rotating rod 94 is longitudinally slidably connected to the inside of the supporting frame 3 .

[0031] In this embodiment, since the inner top end of the sealing cavity 91 is connected to the inner bottom end of the sealing groove 5 , it can be ensured that the air pressure inside the sealing cavity 91 is equal to that inside the sealing groove 5 .

[0032] The working principle and use process of the utility model are as follows: when in use, the support frame 3 is placed in the specified position, and then the driving motor 10 is started. The driving motor 10 drives the driving bevel gear 14 to rotate through the active bevel gear 11, the transition bevel gear 12 and the rotating shaft 13. The driving bevel gear 14 drives the limiting cylinder 96 to rotate through the driven bevel gear 97. The limiting cylinder 96 drives the spiral drill bit 98 to rotate at high speed through the rotating rod 94. Then, by stepping on the top plate 8, the top plate 8 drives the sealing plate 6 to slide downward through the connecting block 7. At this time, the inner bottom end of the sealing groove 5 is in a strong pressure state, and the inner top end of the sealing cavity 91 is also in a strong pressure state, and drives the rotating rod 94 and the spiral drill bit 98 through the sealing block 92 and the first bearing 93. The spiral drill bit 98 slides downward, and the spiral drill bit 98 slides downward at the same time when rotating at high speed until it goes deep into the ground. At this time, the drive motor 10 can be turned off, and the support frame 3 and the vertical pole 1 are fixed, which improves the stability of the drilling equipment body 2 during operation. When it is not needed, the drive motor 10 is started to drive the active bevel gear 11 to rotate in the opposite direction, which can eventually make the spiral drill bit 98 rotate in the opposite direction and gradually leave the ground. Through the elasticity of the elastic block 15, the sealing plate 6 will slide upward, and the spiral drill bit 98 can automatically retract into the interior of the support frame 3, which can avoid the spiral drill bit 98 from scratching the ground when the equipment as a whole is moving, thereby extending the service life of the spiral drill bit 98.

[0033] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
