Abstract

The utility model relates to a large-diameter drilling tool for drilling and coring of hard rock, which belongs to a construction machine, and the utility model is composed of an integral outer drill bushing, an inner drill bushing, hidden hammers uniformly distributed in a lower ring opening of the drill bushing, drill rods connected with the upper ends of the outer and the inner drill bushings, a static lifting beam connected with the upper end of the drill rod and a joint. Magazine cases are uniformly distributed at the lower ring openings of the inner and the outer drill bushings, tilting fillets of inclined slide ways are uniformly distributed at the lower part of the outer drill bushing, a slip is arranged in each tilting fillet, and each slip is connected with the inner wall of the outer drill bushing by a hydraulic cylinder. Each hydraulic cylinder is respectively connected with a branch water pipe, when drilling device reaches certain depth, the cumulative shells in the magazine cases can be detonated so as to cut off rock cores from roots, and the slip can clamp the rock core and can be suspended out of pile holes together.

Description

Major diameter hard rock drilling and core bit
The utility model belongs to the building machinery class.
In industry and civilian construction, major diameter is irritated the stake technology and has been obtained general application.This technology at first is to get out a hole in the building site by drilling tool, annotates stake at stake Kong Zhongyong steel concrete then.When drilling tool bored the stake hole, a lot of situations will get out a hole on hard rock, needed broken back to take out from the stake hole to core, and is cumbersome time-consuming and bothersome.Getting out at present the drilling tool in a hole on hard rock, is outer drill bushing and the interior drill bushing by one, is distributed on that the pneumatic down hole hammer in the collar extension under the drill bushing, drilling rod that the drill bushing upper end connects, static bale handle that the drilling rod upper end connects and joint form.Its operation process is: the rotating disk of rig blocks drilling rod and rotates together, make the outer drill bushing and the interior drill bushing of one reach down-the-hole hammer rotation together uniform in the following collar extension, guide the reciprocal motion fractured rock of tup high speed that following tracheae makes each down-the-hole hammer into by the joint of drilling tool upper end, be broken out the deep trouth of an annular of rock, the middle part forms a core, proposes drilling tool afterwards, and core takes out by hand breaking, form a stake hole, annotate stake at stake Kong Zhongyong steel concrete at last.
The purpose of this utility model is: provides a kind of the major diameter core do not adopted fragmentation, and the major diameter hard rock drilling and the core bit that adopt monoblock to extract.
The technical solution of the utility model is: based on by the outer drill bushing of one with interior drill bushing, be distributed on the pneumatic down hole hammer in the collar extension under the drill bushing, the drilling rod that inside and outside drill bushing upper end is connected, the static bale handle of drilling rod upper end connection and the major diameter hard rock drilling drilling tool that joint is formed; The following collar extension of drill bushing and interior drill bushing is evenly equipped with the magazine of tubbiness outside; Be evenly equipped with watt seat of inclined ramp outside on the drill bushing lower inner wall, in each watt seat slips be housed, each slips is connected on the inwall of outer drill bushing by hydraulic cylinder; Each hydraulic cylinder is connected with a branching pipe respectively.
Major diameter hard rock drilling of the present utility model and coring bit, making boring and taking out core is one, having the saves time high good effect of efficient of saving trouble.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of bale handle joint of the present utility model.
Drawing explanation and embodiment are described below: 8 is outer drill bushings, the 7th among the figure, interior drill bushing; Be evenly equipped with pneumatic down hole hammer 1,2nd in the following collar extension of outer drill bushing 8 and interior drill bushing 7, tup, under pneumatic effect, tup 2 back and forth impacts hard rock at a high speed, and fragmentation goes out an annular deep trouth on hard rock, and the middle part forms a core 6.Outer drill bushing 8 is connected with drilling rod 12 and 15 with interior drill bushing 7 upper ends, and the 13rd, the flange that drilling rod 12 is connected with 15.Drilling rod 15 is clamped and is rotated by the chuck 14 of rig.The upper end of drilling rod 15 is connected on the joint 16 of static multi-path, and the 17th, be connected the bale handle on the joint 16.The utility model following collar extension of drill bushing 8 and interior drill bushing 7 outside is evenly equipped with the bullet logical sequence 3 of tubbiness, is evenly equipped with watt seat 4 of inclined ramp outside on drill bushing 8 lower inner wall, and each slips 4 is connected on the inwall of outer drill bushing 8 by hydraulic cylinder 5.The water inlet pipe B of static lift-type joint 16 enters press water, and water enters standpipe 10 through water pipe, and standpipe 10 is connected with each hydraulic cylinder 5 through branching pipe respectively again, and hydraulic cylinder 5 shrinks under the effect of hydraulic pressure, makes slips 4 along moving to top dead centre on the slideway.Standpipe 10 sneaks in the water through drilling rod 15 (hollow section), joint 16, rotation adapter 22, scum pipe A outflow the rock ash of tup 2 fragmentations also to the front side jetting of each down-the-hole hammer.The pressure air that air inlet pipe C on the joint 16 introduces is connected with each down-the-hole hammer 1 through air inlet pipe, cylinder 9, bronchus, and pressure air makes the tup 2 of down-the-hole hammer 1 move back and forth broken hard rock at a high speed.In the tubbiness bullet logical sequence 3 that the following collar extension of drill bushing 8 and interior drill bushing 7 is evenly equipped with the cumulative bullet is housed outside, when drilling equipment after getting into certain depth on the hard rock, rig and rotating disk stop operating, air inlet pipe C on the joint 16 and water inlet pipe B stop the air inlet water inlet, down-the-hole hammer 1 quits work, because of the pressure of cutting off the water hydraulic cylinder 5 elongation that progressively disappears, slips 4 glides the top to core 6; At this moment lighting the fire lock of leading on ground, that cumulative in the magazine 3 is upspring is quick-fried, and core 6 is cut off from root.Adopt crane that the core 6 of bale handle 17, joint 16, drilling rod 15 and 13, outer drill bushing 8 and interior drill bushing 7, slips 4 and clamping is hung out a hole together at last.The bale handle that the utility model adopted and the structure of joint are as shown in Figure 2.17 is bale handles among the figure, the 23rd, with bale handle 17 be the housing of one, housing upper end has deslagging A, side that water inlet pipe B and air inlet pipe C are arranged; Be equipped with in housing 23 and take over 22, taking on 22 has water pipe sleeve 21 gentle pipe boxes 20, and there is joint 19 water pipe sleeve 21 lower ends, and tracheae overlaps 20 lower ends and connects 28; Take over 22 lower ends and be connected with drilling pipe 15 through flange 18, the top and the bottom of adapter 22 are assemblied in housing 23 centers by bearing 24 and packing seal 25.26 is platens among the figure, and the jackscrew 27 on the housing is pushed platen 26 seals packing seal 25 butt tubes 22.Drill bushing 8 upper ends can be extended out the bucket 11 that connects material outside, make an earth that fall down the upper end, hole fall into bucket 11.
