Technical Field

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

[0002] Blowout during drilling in coal mines refers to the phenomenon that coal seams, gas or other geological gases are rapidly ejected from the borehole due to internal stratum pressure or rock fractures during drilling operations. Blowout is a common problem in coal mine operations. Blowout is accompanied by the ejection of a large amount of harmful gases such as gas and coal dust, increasing the safety risks of explosion and suffocation inside the mine. Especially if the gas content is high, it may cause a serious gas explosion accident, endangering the lives of miners.

[0003] A Chinese utility model patent with announcement number CN217233579U discloses a drilling blowout prevention device for gas control. The device provides external shielding and protection around the borehole and recycles waste such as coal slag and gas. However, the device cannot effectively adhere to the mine wall and is prone to falling off during the blowout process. At the same time, it is unable to effectively clean and wipe the drill bit to reduce the wear of the drill bit. Utility Model Content

DETAILED DESCRIPTION

[0022] refer to Figures 1 to 7 A drilling hole anti-blowout device for gas control shown in the figure includes a processing component 1, on which a gas recovery box 102 and a solid recovery box are arranged. The processing component 1 is used to recycle waste generated during blowout. A recovery component 2 is slidably arranged on the processing component 1. The recovery component 2 is always in contact with the mine wall. When a blowout occurs, the waste is quickly recovered. The recovery component 2 cleans the propulsion tube 105 and the drill bit 106 on the processing component 1 to reduce the loss of the propulsion tube 105 and the drill bit 106.

[0023] The processing component 1 includes a base 101, a gas recovery box 102 is arranged at the upper end of the base 101, a recovery pipe 107 is arranged on the gas recovery box 102, a filter plate 108 is arranged in the recovery pipe 107, the filter plate 108 filters the recovered gas to prevent solid matter from entering the gas recovery box 102, an extraction pump is arranged in the gas recovery box 102, and the extraction pump extracts the gas waste in the recovery component 2 through the recovery pipe 107, and a motor 104 is slidably arranged on the base 101, and a motor 104 is arranged on the motor 104. There is a propulsion tube 105, on which a drill bit 106 is rotatably provided, and the drill bit 106 is used to drill holes in the mine wall. A solid recovery box is provided at the lower end of the base 101, and an opening and a plurality of filter plates 109 are provided in the solid recovery box. The filter plates 109 are used to filter solid waste. A baffle 103 is slidably provided on the side of the solid recovery box, and the baffle 103 is used to block the solid recovery box. When the waste in the solid recovery box needs to be removed, the baffle 103 is driven to move to discharge the objects in the solid recovery box.

[0024] The recovery component 2 includes a bonding frame 201 slidably mounted on the base 101, and multiple groups of push rods 203 are slidably arranged on the outer side of the bonding frame 201. A drill bit 202 is rotatably arranged on the push rod 203. When the push rod 203 moves, it drives the drill bit 202 to move. After driving the drill bit 202 to rotate, the push rod 203 is driven to move. The push rod 203 drives the drill bit 202 to insert into the mine wall. After the drill bit 202 is inserted into the mine wall, the bonding frame 201 is fixed. A sealing ring 204 is arranged at one end of the bonding frame 201. The sealing ring 204 is squeezed with the mine wall to prevent waste from being discharged through the gap when the hole is sprayed. A detachable bonding ring 205 is arranged on the bonding frame 201. The bonding ring 205 is replaced according to different specifications of the propulsion tube 105 and the drill bit 106. The bonding ring 205 is used to control the distance between the propulsion tube 105, the drill bit 106 and the inner wall of the bonding frame 201. Since the pressure is relatively high when the hole is sprayed, such as the push rod 203, the pressure is relatively high when the hole is sprayed, such as the push rod 203. If the gap between the inlet pipe 105 and the drill bit 106 is too large, the waste injection range will be increased, and the waste diffusion effect will be increased. The upper end of the laminating frame 201 is provided with a discharge port, and the discharge port of the laminating frame 201 is connected to the gas recovery box 102 through the recovery pipe 107. The lower end of the laminating frame 201 is provided with a discharge box 207, and the discharge box 207 is intermittently laminated with the solid recovery box. The laminating frame 201 is internally provided with a baffle plate 210 for sliding. The baffle plate 210 is opposite to the gas recovery box 102. The material discharge box 207 is used for blocking, and a pushing plate 208 is slidably arranged inside the laminating frame 201. When the pushing plate 208 moves, the solid waste in the laminating frame 201 is discharged through the material discharge box 207. A plurality of wiping plates 206 are slidably arranged at the other end of the laminating frame 201. The wiping plates 206 wipe the pushing tube 105 and the drill bit 106. A protective frame 209 is arranged on the laminating frame 201, and the protective frame 209 is slidably connected to the pushing tube 105.

[0025] Working principle: During operation, the laminating frame 201 is driven to slide on the base 101, and the laminating frame 201 drives the sealing ring 204 to stick to the mine wall, then the laminating frame 201 is stopped, and the drill bit 202 is driven to rotate. At the same time, the push rod 203 is driven to slide on the laminating frame 201, and the push rod 203 drives the drill bit 202 to be inserted into the mine wall. At this time, the drill bit 202 fixes the laminating frame 201 on the mine wall, and the driving motor 104 is driven to slide on the base 101. The motor 104 drives the propulsion tube 105 and the drill bit 106 to pass through the protective frame 209 and the laminating frame 201 to contact the mine wall, and drives the drill bit 106 to rotate, and the drill bit 106 drills a hole in the mine wall.

[0026] When the hole spraying phenomenon occurs, the extraction pump in the gas recovery box 102 is driven to work, and the gas recovery box 102 absorbs and collects the toxic gas in the recovery pipe 107. The filter plate 108 filters the absorbed gas to prevent solid waste from entering the gas recovery box 102. At the same time, the ejected solid debris accumulates in the bonding frame 201. When the drilling is completed, the push rod 203, the bonding frame 201, and the motor 104 are driven to reset, and the bonding frame 201 moves to drive The material discharge box 207, when the material discharge box 207 is bonded with the solid recovery box, the baffle plate 210 is driven to slide in the bonding frame 201, and the pushing plate 208 in the bonding frame 201 is driven to slide, and the pushing plate 208 pushes the solid waste in the bonding frame 201 to the material discharge box 207, and the waste enters the solid recovery box through the material discharge box 207, completing the recovery of the solid waste. When cleaning the solid recovery box, the baffle plate 103 is driven to rise, and the solid recovery box is opened to empty the items in the box.

[0027] When the motor 104 drives the propulsion tube 105 and the drill bit 106 to reset, the wiping plate 206 is driven to slide on the fitting frame 201, and the wiping plate 206 fits with the propulsion tube 105 and the drill bit 106. The wiping plate 206 wipes the surface of the propulsion tube 105 and the drill bit 106 to reduce the wear of the propulsion tube 105 and the drill bit 106.

[0028] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative labor all fall within the protection scope of the present invention.
