The utility model content
To the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of deep hole bad ground major diameter length pipe that narrows to carry and drill through heart drilling tool, can solve the above-mentioned problem that instrument exists that drills through fully.
The technical scheme of the utility model is: a kind of deep hole bad ground major diameter length narrows to manage to carry and drills through heart drilling tool; Comprise one-way valve mechanism, interior pipe mechanism, outer tube mechanism, twin-stage single action mechanism; Pipe mechanism comprises regulating shaft, adjusting nut, adjusting axle sleeve, steel ball, inner pipe joint, water flowing bolt, spring, the pipe that narrows, anchor ear, fixed middle ring, clip spring seat and jump ring in said; Said clip spring seat is connected with the gas thread that narrows, and said twin-stage single action mechanism is by the secondary and following single action of the identical last single action of structure secondary composition, and goes up the secondary and following single action pair of single action and be connected through same; Said twin-stage single action mechanism comprises axle, bearing, bearing spider, gland, sealing ring, packing ring; Have oil filler point on the said bearing spider, said oil filler point is communicated with bearing, and the oil filler point opening part is provided with the bolt that matches; Also comprise telescoping mechanism, said telescoping mechanism comprises spring, water flowing bolt, inner pipe joint and adjusting axle sleeve.
As preferably, said in pipe be divided in the formula that narrows and manage in the pipe and monolithic, and interchangeable, effective steel clip hoop is embraced combination in the said formula that narrows.
As preferably, the said length that narrows pipe is 5-7m.
The beneficial effect of the utility model is: the place, position of bearings of the said bearing support of the utility model is provided with oil filler point, can in the hole, fill with lubricating grease in each back that pulls out of hole, when in the hole, creeping into; Make the bearing spider internal and external pressure balance; Reduce the possibility that drilling fluid gets into bearing spider, give the bearing sufficient lubrication, effectively prevent bearing wear; Said oil filler point opening part is provided with the bolt that matches; Play the effect of inner and outer sealing, make its number of times that can reduce the dismounting of single action mechanism, clean, the design of bolt makes it make things convenient for grease up; Prolong the application life of single action mechanism, guarantee the single action effect; Increased telescoping mechanism, made it when pulling off rock core, the screw thread of can effectively avoid narrowing pipe and clip spring seat is impaired.
