Described slideway 8 entirety is the rectangular structure of hollow.
Owing to have employed above technical scheme; the utility model has following beneficial effect: the effect can not only playing blowout prevention; the more important thing is the water burst in energy Instantaneous Control hole; reduce a large amount of quality time pulling out of hole and delay in times of crisis; provide safety guarantee for underground coal mine from now on bores drilling operation, certain economic benefit can also be brought for enterprise.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment being clearly and completely described.
Referring to Fig. 1, this detailed description of the invention is achieved by the following technical solutions, it comprises pedestal 4, one end of this pedestal 4 is the tubular structure of hollow, the slideway 8 communicated with its inside is provided with in the middle part of it, the end of its one end is connected with the sleeve pipe c be inserted in base plate b by flange 11, its other end is provided with sealing ring 2, the middle part of sealing circle 2 offers and concentric is closely socketed with drilling rod a the closed hole coordinated, about two slide blocks docked 9 are provided with in described slideway 8, this slide block 9 coordinates with slideway 8 piston, the upper end of described slide block 9 is fixed with screw rod 7, one end that this screw rod 7 is positioned at outside is passed and its gland 6 coordinated that spins, described gland 6 is fixed on the end of slideway 8 by interior six side's screws, described device is provided with two writing brushes 5 and six be connected with its inside and is in charge of 10, the both sides that 10 are separately positioned on slideway 8 are in charge of by two described writing brushes 5 and six.
Described slide block 9 is fixed with weather strip 12.
One end that described pedestal 4 is positioned at sealing ring 2 inwardly mills out circle dead eye concentric with it, and this dead eye internal fixtion has sliding bearing 3.
Described sealing ring 2 entirety is the tubular structure of hollow, the tight socket connection of dead eye of its periphery and sliding bearing 3, the bottom of the edge laminating sliding bearing 3 bottom it extends outward the concentric fixed edge of a circle, the opposite side of this fixed edge is provided with the transparent cover 1 of gap laminating with it, and itself and pedestal 4 to be spun by interior six side's screws and be integrally fixed by described transparent cover 1.
Described slideway 8 entirety is the rectangular structure of hollow.
Below in conjunction with accompanying drawing, the using method of technical scheme in this detailed description of the invention and principle thereof are further elaborated:
Gland 1 is by interior six side's screws, sealing ring 2 and sliding bearing 3 is made to be fixed in the dead eye of pedestal 4 end, the top of two writing brushes 5 connects ball valve, gland 6 passes through the openend compact siro spinning technology of interior six side's screws and slideway 8 equally, rotary screw 7 can pull in the coffin of slide block 9 in slideway 8 and slide, six are in charge of 10 top Bonding pressure table and pipe valves, and whole device entirety is by the Flange joint of flange 11 with sleeve pipe c, and drilling rod a is by friction belt movable sealing 2 rotary drilling together with sliding bearing 3.
