Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a drilling anti-blowout hole device for gas control. Background Art

[0002] Gas is formed when cellulose and organic matter from ancient plants are decomposed by anaerobic bacteria in the early stages of coal formation. In a high-temperature, high-pressure environment, gas continues to be generated due to physical and chemical reactions while coal is being formed. When using directional long drilling to pre-extract gas from the mining face or drift in high-gas or outburst mines, the gas pressure in the hole is relatively high during drilling due to the complex geological occurrence of gas in the mining face. This huge pressure sprays the drill cuttings out of the hole through the gap between the drill rod and the borehole, leading to the widespread occurrence of top drilling and blowholes. During blowholes, high-concentration gas and coal powder gush out of the borehole in large quantities. As the concentration of the gushing gas increases, the friction between the coal powder and external objects during the spraying process generates heat, which may lead to gas explosions and other safety-threatening accidents.

[0003] The Chinese patent with the announcement number CN217233579U discloses a drilling blowout prevention device for gas control, which includes a high-pressure nozzle, an electric lifting platform, a protective cover, a motor, a drain outlet, a slag outlet and a bracket; a bracket is provided above the workbench of the electric lifting platform; the protective cover is arranged between the two brackets and is hinged to the bracket through a rotating shaft, and one of the brackets is provided with a motor connected to the rotating shaft; a drain outlet is provided at the bottom of the protective cover, and a slag outlet is provided above the protective cover; a high-pressure nozzle with a water outlet facing the middle of the protective cover is provided inside the protective cover. This application can provide external shielding and protection around the borehole during the drilling process, and can promptly suck away and dispose of the coal slag, gas and water generated by the drilling while drilling, to prevent gas and coal dust from exploding in the mine tunnel; and is equipped with a gas alarm and a high-pressure nozzle, which can spray water at the drilling position of the drill bit to prevent sparks, and can promptly notify construction personnel to evacuate, ensuring construction safety.

[0004] However, the above-mentioned publicly disclosed solution has the following shortcomings: in actual use, the above-mentioned solution sprays water during the drilling process to reduce the temperature of the drilling position and prevent gas combustion. In actual use, the cooling effect of the water spray is unstable, and the water flow will block the staff's line of sight, making it impossible to accurately judge the drilling position.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-7 The utility model is described in further detail.

[0035] Example 1, as Figure 1-Figure 7As shown, in order to solve the existing problems, in this embodiment, the utility model discloses a drilling and anti-blowout hole device for gas control, including a docking shell 1, a docking bracket 3 is connected to the side of the docking shell 1, the docking bracket 3 is provided with a through hole, a bolt 4 is slidably connected to the inner wall of the through hole, the bolt 4 is threadedly connected to the side of the mounting shell 2, a punching component 5 is connected to the outer side of the docking shell 1, and a pressurizing component 6 is connected to the mounting shell 2.

[0036] The punching component 5 includes a lifting bracket 501 connected to the docking shell 1, the top of the lifting bracket 501 is connected to a motor bracket 504, the motor bracket 504 is connected to a lifting motor 502, the output end of the lifting motor 502 is connected to a lifting threaded rod 503, the lifting threaded rod 503 is threadedly connected to a lifting member 505, the lifting member 505 is slidably connected to the lifting bracket 501, and the side of the lifting member 505 is connected to a connecting member 506.

[0037] The top of the connecting member 506 is connected to a rotating motor 507, and the bottom output end of the rotating motor 507 is connected to a sliding shaft 508. The docking shell 1 is provided with a through hole, and the docking shell 1 is rotatably connected to a sealing ring 509. The sealing ring 509 is slidably connected to the sliding shaft 508. A groove is provided on the side of the sliding shaft 508, and the sealing ring 509 is provided with a protrusion, which is slidably connected to the inner wall of the groove.

[0038] One end of the sliding shaft 508 away from the rotating motor 507 is connected to a docking piece 510 , and the other end of the docking piece 510 is connected to a docking groove 511 , and an inner wall of the docking groove 511 is connected to a drill bit 512 .

[0039] The pressure-applying component 6 includes a fixed clamping bracket 602 connected to the outer side surface of the mounting shell 2. The outer end surface of the mounting shell 2 is provided with a sliding groove. The sliding groove is slidably connected to a sliding clamping bracket 601. The sliding clamping bracket 601 is provided with a through hole. The inner wall of the through hole is slidably connected to a clamping threaded rod 603. The other end of the clamping threaded rod 603 is threadedly connected to the fixed clamping bracket 602.

[0040] The fixed clamping bracket 602 is docked with a high-pressure gas tank 604, and the high-pressure gas tank 604 is docked with the sliding clamping bracket 601. A control valve is connected to the top of the high-pressure gas tank 604, and a connecting air pipe 605 is connected to the side of the control valve. The other end of the connecting air pipe 605 passes through the mounting shell 2 and extends into the interior of the mounting shell 2.

[0041] The specific working principle is: this device can effectively improve the stability of gas pipeline drilling processing. Compared with traditional devices, there is still a pressure difference between the inside and outside during the drilling process. This device can make the pressure inside and outside the pipeline the same by wrapping it in a shell, thereby preventing the pipeline from deforming during the drilling process.

[0042] When this device is used, the combination of the docking shell 1 and the installation shell 2 can achieve a sealing wrapping effect on the pipeline. After the docking is completed, the shells are combined with each other by bolts 4 to achieve sealing. At this time, the high-pressure gas tank 604 is fixed by the clamping structure, and the control valve and exhaust valve 606 of the high-pressure gas tank 604 are opened. In the process of the high-pressure gas tank 604 discharging the flame-retardant gas, the air inside the shell is squeezed out and flows out from the exhaust valve 606. After a period of time, most of the gas inside the shell is flame-retardant gas. At this time, the exhaust valve 606 is closed, and the high-pressure gas tank 604 continues to be opened. At this time, the air pressure inside the shell begins to rise, and when the air pressure requirement is reached, the high-pressure gas tank 604 is closed.

[0043] At this time, the lifting motor 502 drives the lifting threaded rod 503 to rotate, thereby realizing the lifting and sliding effect of the lifting member 505. The structure of the connecting member 506 can drive the rotating motor 507 to move up and down, thereby realizing the effect of driving the sliding shaft 508 to lift and slide while driving the sliding shaft 508 to rotate through the rotating motor 507.

[0044] The sealing ring 509 can be driven to rotate by the groove of the sliding shaft 508, and the sealing ring 509 can make contact with the side of the sliding shaft 508 and the side of the sealing ring 509, thereby ensuring the sealing performance of the device.

[0045] The lifting, sliding and self-rotating movement of the sliding shaft 508 can drive the drill bit 512 to drill holes.

[0046] Example 2, as Figure 1-Figure 7 As shown, in order to solve the existing problems, in this embodiment, based on the same concept as the above-mentioned embodiment 1, this drilling and anti-blowout hole device for gas control also includes: the outer side surface of the mounting shell 2 is penetrated by an exhaust valve 606, the mounting shell 2 is provided with a seal, and the seal is arranged at the joint between the mounting shell 2 and the connecting air pipe 605, the side surfaces of the mounting shell 2 and the docking shell 1 are provided with arc-shaped grooves, the side walls of the arc-shaped grooves are provided with extrusion seals, and the centers of the arc-shaped grooves of the mounting shell 2 and the docking shell 1 are the same.

[0047] The specific working principle is: this device can effectively improve the stability of gas pipeline drilling processing. Compared with traditional devices, the drilling environment of this device is in a pressure balance state, thereby avoiding problems such as deformation of the drilling position due to pressure difference.

[0048] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
