Description
Technical field
A kind of underground work boring of the utility model protective cover, the protective cover used when relating to a kind of downhole safety bore operation, belongs to mining equiment field.In particular to a kind of down-hole drilling that can effectively prevent when high methane work environment work, carry out explosion-proof and the protective cover carrying out boring dust collection can be assisted.
Background technology
At present, miner under-well work runs into the work needing boring sometimes, and the inner rock stratum of mine is complicated, the scope of operation has rock to exist often, tiny rubble may be sputtered in boring procedure, likely injure the eyes of staff, the personnel of hindering one's work hole the carrying out of normal work, and high methane environment is often faced in mine, be unsuitable for carrying out exposed bore operation, drill bit works long hours and easily produces spark with rock crash later thus cause strong explosion accident, cause casualties and property loss, in addition, a large amount of dust can be produced while boring, these dust are to the skin of constructor, cornea, mucous membrane produces spread effect, time has been grown and can cause a series of pathology, and when soot density reaches certain condition, just have potential safety hazard, run into naked light and cause blast, but dust is not easy after being diffused into surrounding environment by source to carry out collecting and processing again, and existing cleaner can not be collected for the dust that localized borehole operation produces among a small circle, the dust causing bore operation to produce causes direct or indirect harm to personnel in the pit.
Summary of the invention
In order to improve above-mentioned situation, the protective cover that a kind of underground work of the utility model boring protective cover uses when providing a kind of downhole safety bore operation, can effectively prevent down-hole drilling when high methane work environment work, because drill bit works long hours, and produce spark with the shock of rock, cause the problem of gas explosion, carry out boring dust collection simultaneously, improve the working environment residing for staff, improve the safety factor of down-hole drilling operation.
A kind of underground work of the utility model boring protective cover is achieved in that a kind of underground work boring of the utility model protective cover is made up of fastening devices and protector.Fastening devices is made up of fixed knob, auxiliary knob and retainer ring.Fixed knob and auxiliary knob are placed on retainer ring respectively, and protector is made up of secondary spring, main spring, auxiliary telescopic bar, arc expansion link, dust cover, replaceable protective pad, anti-explosion cover, rotating hole, annular stator, fixing hole, connector and connecting axle.Annular stator is placed in dust cover side opening part, multiple fixing hole is placed on annular stator, anti-explosion cover is placed on dust cover, dust cover just has rotating hole to opening direction side, replaceable protective pad is placed on rotating hole, connector is placed on anti-explosion cover, and be connected with dust cover, auxiliary telescopic bar one end is placed on retainer ring, the other end is placed on anti-explosion cover, and be positioned at rotating hole side, secondary spring is placed on auxiliary telescopic bar, arc expansion link is parallel to auxiliary telescopic bar, and one end is placed on retainer ring, the other end is placed on anti-explosion cover, and be positioned at rotating hole opposite side, main spring is placed on arc expansion link.
During use, first by by the fixed knob on retainer ring and auxiliary knob, the brill making Fixing shrink ring be placed in pneumatic drilling machine is in, then make drill bit pass and rotating hole changes protective pad, be deep in dust cover, described replaceable protective pad can be made up of annular shield pad, can change according to bit diameter.Then connector is connected with external dust gathering-device, then the annular stator on dust cover is made to be pressed in the scope of operation, by the fixing hole on annular stator, this dust cover is fixed on bore operation face afterwards, also can according to actual job needs, directly be fixed in the scope of operation without fixing hole, now need operating personnel to compress rig, under the secondary spring of dust cover on auxiliary telescopic bar and the main spring acting in conjunction on arc expansion link, can the scope of operation be close to.Then pneumatic drilling machine can be used to carry out bore operation, described auxiliary telescopic bar and arc expansion link, deeply can hole along with drill bit, stretch, secondary spring simultaneously on auxiliary telescopic bar, compress between anti-explosion cover and retainer ring, main spring on arc expansion link, compress between anti-explosion cover and retainer ring, the dust that bore operation produces can flow into dust collecting from connector, anti-explosion cover can play explosion-proof, the spark that can prevent bore operation from producing contacts with external procedure environment facies, after operation completes, under secondary spring elastic force, auxiliary telescopic bar is made to return to original state, under the elastic force of main spring, arc expansion link is made to return to original state, reach the object of carrying out safe drill operation protection in down-hole.
beneficial effect.
One, structure is simple, convenient and practical.
Two, with low cost, be easy to promote.
Three, effectively can improve the working environment residing for staff, improve the safety factor of down-hole drilling operation.
