Description
Technical field
The utility model belongs to coal-bed flooding technical field, is specifically related to a kind of rapid hole sealing device utilizing the water filling of extraction hole.
Background technology
For coal-bed flooding field domestic at present, a kind of method carries out water filling by special coal seam water injection hole of constructing; Another kind of then be utilize work plane early stage construction extraction borehole carry out coal-bed flooding, and the drilling and sealing technique of coal-bed flooding mainly contains two kinds, cement injection sealing of hole and polyurethane sealing of hole respectively, according to the up-to-date administrative provisions used about macromolecular material issued, polyurethane hole-sealing technology is also eliminated substantially, and mostly remaining be cement injection hole-sealing technology.
For highly gassy mine, all fully-mechanized mining workings are all covered by concordant extraction borehole, do not need construction coal water injection hole separately again, can directly utilize existing extraction borehole to carry out coal-bed flooding.Mine extraction borehole removes as after back production mash gas extraction effect in early stage, can hole as Seams water filling at stoping period, in the extraction borehole removed, sealing of hole section pipe fitting is expendable, therefore, first coal-bed flooding sealing of hole will utilize the drilling rod that diameter is 94mm to carry out trepanning (reaming) operation, and the hole sealing tube in foramen primum, sealing of hole cement paste are all destroyed and drawn out, and then utilizes zinc-plated irony pipe fitting and cement paste to carry out sealing of hole water filling.This technique destroys original sealing of hole condition on the one hand, affects sealing quality, and its technological operation is loaded down with trivial details on the other hand, and on-the-spot recruitment per tour reaches 4, wastes time and energy, and the zinc-plated irony pipe fitting of water filling is not recyclable yet, causes cost to waste.
Summary of the invention
The utility model carries out water filling to fast and effeciently utilize former extraction borehole, and then provides a kind of rapid hole sealing device utilizing the water filling of extraction hole.
The utility model adopts following technical scheme:
A kind of rapid hole sealing device utilizing the water filling of extraction hole, comprise the hole sealing tube be placed in extraction hole, one end of hole sealing tube hangs outside extraction hole, described hole sealing tube outstanding go out termination be provided with taper tapping, the tapered thread section of taper tapping and hole sealing tube are connected, the described section of being connected is fastening by clip, and clip is located at hole sealing tube periphery.
Described clip comprises the snap ring having mounting groove, and mounting groove is along the elongated setting of snap ring axis direction, and mounting groove place is provided with some fastening bolts.
The length of described clip is greater than taper tapping tapered thread segment length.
The termination of described taper tapping is also provided with operation tapered end.
The utility model has following beneficial effect:
1, the utility model device directly utilizes the hole sealing tube in former extraction borehole to carry out sealing of hole, just can realize at the fully-mechanized mining working of existing extraction borehole, former hole-sealing technology can not be destroyed, and singlely can to complete in 10 minutes, the effective raising water-injection efficiency of energy, ensure that carrying out of coal-bed flooding work;
2, the utility model device carries out sealing of hole by taper tapping and being connected of hole sealing tube, utilize clip fastening simultaneously, ensure that taper tapping and hole sealing tube can fully extrude tight, good airproof performance, improve sealing quality, avoid in water filling link because water filling affects construction speed;
3, taper tapping and clip remove and install conveniently, can reuse, can effectively control cost.

Detailed description of the invention
By reference to the accompanying drawings, detailed description of the invention of the present utility model is described further:
The rapid hole sealing device utilizing the water filling of extraction hole as shown in Figure 1, comprise the hole sealing tube 1 be placed in extraction hole 4, one end of hole sealing tube 1 hangs outside extraction hole 4, described hole sealing tube 1 outstanding go out termination be provided with taper tapping 3, tapered thread section 32 and the hole sealing tube 1 of taper tapping 3 are connected, the described section of being connected is fastening by clip 2, and it is peripheral that clip 2 is located at hole sealing tube 1.
When after dismounting extraction pipe fitting, hole sealing tube 1 used when still remaining original sealing of hole extraction in extraction borehole (the extraction hole 4 namely in Fig. 1), one end of this hole sealing tube hangs outside extraction hole, make the tapered thread section 32 of taper tapping 3 and hole sealing tube 1 outstanding go out end be connected, then the fastening aforementioned cooperation linkage section of clip 2 is utilized, shown clip 2 comprises the snap ring 21 having mounting groove 23, mounting groove 23 is along the elongated setting of snap ring 21 axis direction, mounting groove 23 place is provided with some fastening bolts 22, as shown in Figure 2,3.First clip 2 is placed on the outstanding section of the going out periphery of hole sealing tube 1 during installation, is screwed into after in hole sealing tube 1 until taper tapping 3, is fastened by bolts the mounting groove 23 of clip 2.In order to ensure sealing effectiveness, the length of clip 2 should be greater than tapered thread section 32 length of taper tapping 3, makes threaded engagement section can be completely fastening by clip.
Conveniently be screwed into taper tapping 3, its termination is provided with operation tapered end 31 as shown in Figure 4, when taper tapping and hole sealing tube physical dimension larger time, can tighten by the aid such as steel pipe, large-scale spanner, faster laborsaving.
