Description
Technical field
The present invention relates to mine safety appliance, refer to particularly a kind of mine drop shaft safety protection structure.
Background technology
Drop shaft is the facility that underground mines stored and transported mineral, and mineral transport by drop shaft.Vibration ore dumping machine is important the establishing that drop shaft is produced, and is installed on the bottom of drop shaft, and the maintenance of vibration ore dumping machine is the potential safety hazard of mine maintenance.At present, the safety precautions of maintenance vibration ore dumping machine is at drop shaft open wiring top Build Security platform, need operation in drop shaft in the process of Build Security platform, if the cleaning of the borehole wall of drop shaft is unclean before maintenance, there is floating quarrel, or pit shaft wall rock loosening, workman enters Build Security platform in drop shaft very large risk; In addition, because the field condition of drop shaft is limit, institute's security platform of taking unreliable, adds that drop shaft periphery brags or change the environmental factors such as big gun, and the security platform of taking is easily collapsed, and causes unexpected generation.
Summary of the invention
The object of the invention is provides a kind of mine drop shaft safety protection structure for the problems referred to above, and for the maintenance of Pass drawing equipment provides security protection, this safety protection structure is firm firm, and manual operation, automatically completes, and enters operation in drop shaft without workman.
For achieving the above object, the scheme that the present invention adopts is: a kind of mine drop shaft safety protection structure, comprise the fixed bearing that is arranged on top, drop shaft mouth outside, the drop shaft mouth of described fixed bearing below is provided with cylinder support, the head end of described fixed bearing and girder is hinged, between described girder leading portion and described cylinder support, be hinged with upper cylinder, the back segment of described girder pushes up along and extends in drop shaft mouth against drop shaft mouth, the end of described girder and auxiliary girder head end are hinged, described auxiliary girder end is against drop shaft mouth bottom surface, between described auxiliary girder and described girder back segment, be hinged with lower oil cylinder, the top of described girder back segment is provided with upper cover plate, the inner side of described auxiliary girder is provided with back shroud.
Further, described auxiliary girder is straight beam, and the angle between itself and drop shaft mouth bottom surface is less than 80 °.Make auxiliary girder take drop shaft base plate as secant, to stop auxiliary girder to rotate to ore drawing device orientation; Described girder and a protective unit of auxiliary girder composition, a protection face of several unit compositions, covers whole pit shaft.
Again further, the open wiring top of described cylinder support below drop shaft mouth is provided with lower draw-bar, and described girder leading portion is provided with connecting ring, and described connecting ring buckles and is connected with described lower draw-bar.Connecting ring is for being fixed on lower draw-bar by girder, make safety safeguard structure have three fixed points, that is: buckling a little of the contact point in the pin joint of girder and fixed bearing, auxiliary girder and shaft bottom, and connecting ring and lower draw-bar, thus integrally-built firm steadiness improved.
Further, described girder is bending, and the back segment of described girder and described auxiliary girder connect into knuckle shape.Girder lateral buckling from drop shaft mouth enters in drop shaft mouth, makes to enter operation in drop shaft without workman in the build process of safety safeguard structure; The back segment of auxiliary girder and girder is knuckle shape and is furnished with to be beneficial to oil cylinder is installed therebetween, make auxiliary girder tensible freely, collapsible, convenient installation and space layout.
Compared with prior art, tool of the present invention has the following advantages:
One, compare traditional workman and enter the security platform building in drop shaft, safety safeguard structure can complete installation process in drop shaft mouth outside, can manual operation after installing, automatically complete, enter drop shaft inside processing without workman, avoided clearing up unclean because of pass, or the potential safety hazard brought of pit shaft wall rock loosening, for the maintenance of Pass drawing equipment provides security protection.
Its two, the present invention adopts multiple spot fixed form, has strengthened the fixing of fixed connection place, has also improved integrally-built steadiness.
Its three, the hinged oil cylinder of the present invention, makes safety protection structure energy free-extension, the used time can not accepted and be hung on top board, without frequent dismounting, has also solved the problem of keeping away big gun; And convenient to use, can save a large amount of repair times, reduce labor strength.
Its four, safety safeguard structure can one-object-many-purposes, except for security protection, slightly reequips, just can be in the time producing instead of dedicated ore drawing gate, while preventing ore drawing, run ore deposit.
