Description
Technical Field
The utility model belongs to the technical field of the colliery is bottom is taken out lane and is worn layer drilling pull throughs in pit.
Background
In order to ensure the safety of a coal mine, before the coal face is mined and produced, gas extraction is carried out on the coal seam, so that indexes such as residual gas content and residual pressure of the coal seam reach safety standard regulations. According to the related requirements of gas area control, under the condition of no protective layer mining condition, a bottom suction roadway needs to be arranged in the lower rock stratum of the mined coal bed, a drilling machine is arranged in the bottom suction roadway to construct a through-layer drill hole, and gas extraction is carried out on the mined coal bed by burying extraction pipelines, hole sealing and other work. In actual field construction, after work is finished, the extraction pipeline buried in the penetrated drill hole needs to be sealed, and due to the fact that individual coal seams are soft, in the process of sealing the extraction pipeline buried in the penetrated drill hole, the phenomenon that the hole cannot be sealed due to hole collapse of soft coal sometimes occurs, at the moment, the drill machine needs to be used again for dredging the through hole of the penetrated drill hole, time and labor are consumed, work efficiency is low, the drill machine is used for dredging the through hole, the drill hole sealing pipe can be damaged sometimes, the hole needs to be sealed again after the through hole, and waste is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a coal mine underground bottom suction roadway cross-layer drilling dredging device which is convenient to operate, time-saving, labor-saving and high in efficiency.
In order to realize the above purpose, the utility model discloses a: the high-pressure hose, dredge the straight tube, dredge the drill bit, the rear end of dredging the straight tube is connected with the high-pressure hose, and the front end of dredging the straight tube is connected with dredging the drill bit, is provided with inside passage in dredging the straight tube and dredging the drill bit, is provided with the top venthole on the top of dredging the drill bit, is provided with the lateral wall venthole in the both sides of dredging the drill bit, and the high-pressure hose is linked together through inside passage and top venthole and lateral wall venthole.
When the through hole is collapsed in the cross-layer drilling hole and needs to be dredged, the high-pressure hose can be connected to a compressed air pipeline under a coal mine, a worker holds the rear end of the dredging straight pipe, the dredging drill bit and the front end of the dredging straight pipe are inserted into the through hole, the dredging drill bit and the front end of the dredging straight pipe move back and forth while rotating back and forth, and under the action of manpower and high-pressure air, coal dust or coal cinder in the through hole is discharged out of the through hole. The hole dredging device has the characteristics of convenience in hole dredging operation, time and labor saving, higher efficiency and the like, an original drilling hole sealing pipe cannot be damaged, and the problem of waste caused by hole resealing is solved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The reference numerals are explained below:
1-a high pressure hose; 2-dredging the straight pipe; 3-an internal channel; 4-side wall air outlet holes; 5-dredging the drill bit; 6-air outlet hole at the top end.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As can be seen from fig. 1, the present invention includes: the device comprises a high-pressure hose 1, a dredging straight pipe 2 and a dredging drill bit 5. The rear end of the dredging straight pipe 2 is connected with the high-pressure hose 1, and the front end of the dredging straight pipe 2 is connected with the dredging drill bit 5. The dredging drill bit is set to be conical, so that the dredging drill bit is convenient to dredge and drill, and the rear end of the dredging drill bit is provided with a screw thread which is convenient to be connected with the front end of the dredging straight pipe. The length of the dredging straight pipe is larger than the length of the hole sealing section, so that the through hole dredging operation is facilitated. Be provided with inside channel 3 in mediation straight tube and mediation drill bit, be provided with top venthole 6 on the top of mediation drill bit, be provided with lateral wall venthole 4 in the both sides of mediation drill bit, top venthole and lateral wall venthole communicate with the inside channel of mediation drill bit respectively, and high-pressure hose is linked together through mediation straight tube inside channel 3 and top venthole 6 and lateral wall venthole 4. The high-pressure hose, the dredging straight pipe and the dredging drill bit are all made of antistatic, anti-combustion and corrosion-resistant materials so as to meet the underground use conditions and requirements of the coal mine.
