Description
Technical field
The utility model relates to a kind of plug-hole assembly, particularly relates to a kind of down-hole drilling plug-hole assembly.
Background technology
In mine down-hole recovery process, when roadway or stope and mine locating in the past hole is communicated with time, often by gush out in mine locating boring a large amount of underground water, mud, one is increase drainage underground amount, and two is have a strong impact on roadway or dig up mine to construct.Usual manner is generally that effect is poor with timber artificial water blockoff, but poor for the water under high pressure effect in boring, shutoff is thorough, and has phenomenon, sometimes blocks but continues to leak, sometimes not blocking up at all.
Utility model content
The technical problems to be solved in the utility model is prospected under being to provide a kind of effectively plugged well boring always, stops underground water and mud to gush along holing the down-hole drilling plug-hole assembly of tunnel and stope.
For reaching above-mentioned purpose, a kind of down-hole drilling plug-hole of the utility model assembly, comprise central shaft tube, described central shaft tube upper end is water inlet, lower end is delivery port, described central shaft tube is positioned at below described water inlet and is installed with back taper top board, described central shaft tube to be positioned at below described top board movable sleeve successively and to be connected to rubber gasket and expansion iron cover, described central shaft tube is positioned at described expansion iron cover underside and is connected with adjustment squeezing bushing, described adjustment squeezing bushing top is tapering point, described adjustment squeezing bushing tapering point be threaded with described central shaft tube and can activity adjustment in described expansion iron overlaps.
Wherein said central shaft tube water outlet is provided with valve, closes or water outlet for controlling delivery port.
Wherein said rubber gasket is the multilayer rubber sealing pad of multiple parallel arranged.
Wherein said adjustment squeezing bushing body is threaded with described central shaft tube.
The utility model down-hole drilling plug-hole assembly difference from prior art is that the utility model achieves following technique effect:
The utility model down-hole drilling plug-hole assembly effectively can reduce the cost of fetching water of local, down-hole, the underground water that minimizing comes along boring and mud are to the harm of Underground working site, improving working environment at coal mines sanitary standard, under certain environment, can also be that downhole production is used harmful underground water.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Description of reference numerals: 1-water inlet; 2-central shaft tube; 3-top board; 4-rubber gasket; 5-expansion iron cover; 6-regulates squeezing bushing; 7-valve; 8-delivery port.
Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
A kind of down-hole drilling plug-hole of the utility model assembly, as illustrated in fig. 1 and 2, described down-hole drilling plug-hole assembly comprises central shaft tube 2, central shaft tube 2 upper end is water inlet 1, lower end is delivery port 8, central shaft tube 2 is positioned at below water inlet 1 and is installed with back taper top board 3, central shaft tube 2 to be positioned at below top board 3 movable sleeve successively and to be connected to multilayer rubber sealing pad 4 and expansion iron cover 5, central shaft tube 2 is positioned at expansion iron overlap 5 underside be connected with regulate squeezing bushing 6, squeezing bushing 6 top is regulated to be tapering point, squeezing bushing 6 tapering point is regulated to be threaded with central shaft tube 2 and can to overlap in 5 by activity adjustment to expansion iron, central axis, 2 water outlet 8 mouthfuls places are provided with valve 7, close or water outlet for controlling delivery port.
During use, being filled in by this assembly needs in the boring of leak stopping, and it fills in the degree of depth is that expansion iron cover must enter in boring completely, and the rock of rubber gasket and the residing bore position of expansion iron cover is complete, be beneficial to sealing mat sealing and namely expansion iron cover supports this assembly.After boring filled in by assembly, plug-hole personnel utilize instrument according to operation field situation or firmly keep this assembly filled in boring to stablize and do not rushed out by hole Nei Shui, simultaneously, operating personnel utilizes pipe wrench to turn adjustment squeezing bushing clockwise, under expansion iron is enclosed within the promotion regulating squeezing bushing, multilayer rubber sealing assembly is driven to draw close to top board, because top board inboard is taper, overlap in continuous compaction process at top board and expansion iron, sealing mat outer ring is caused greatly also to increase by the taper surface support inside top board inside multilayer rubber sealing pad, squeezing bushing is regulated constantly to tighten, sealing mat outer ring constantly increases, until sealing mat outer ring contacts completely with drill hole inner wall, gap simultaneously between multilayer rubber sealing pad due to top board and expansion iron be enclosed within the promotion of compression assemblies under disappear, multilayer rubber sealing pad forms a seal, this time, water in boring is blocked completely by the seal that multilayer rubber sealing pad is formed, continue to turn adjusting sleeve pipe, the expansion of multilayer rubber assembly is limited by drill hole inner wall, cannot be extruded again, expansion iron cover is forced to along regulating compression assemblies conical surface dilatancy until iron cover contacts with drill hole inner wall, now, regulate squeezing bushing cannot continue to turn, the effect of expansion iron sleeve anti-drop is formed, whole plugging operations is thorough to be completed.
For there being the boring needing to utilize water, can use and fill valvular device for plugging, after completing leak stopping, connect water pipe, open valve, water in boring can from water inlet centrally central siphon to valve to delivery port, need not utilize the central shaft tube of water can directly from the direct Seal treatment of water inlet.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
