Fig. 2 is the sectional view of cord coring drill shown in Figure 1 at the vertical middle section place vertical with the cutting plane of Fig. 1;
Fig. 3 utilizes cord coring drill shown in Fig. 1 and 2 to realize the structural representation of the two-tube drilling tool of single action.
The specific embodiment
Be described further below in conjunction with the accompanying drawing specific embodiments of the invention.
As illustrated in fig. 1 and 2; Cord coring drill of the present invention comprises outer pipe assembly and inner tube assembly; Outer pipe assembly comprises bullet block head 2, bullet card chamber 7, outer tube 13 and the outer drill bit 15 that connects in order from top to bottom, and inner tube assembly comprises the hinge type spearhead mechanism and bullet fastening position mechanism that connects in order from top to bottom, and inner tube assembly is hung on the hitch in the outer pipe assembly; This inner tube assembly also comprise bearing bore 11, axle 12, in drive pipe 14, bushing pipe 17, clip spring seat 18, jump ring 19 and interior drill bit 20; Wherein, bearing bore 11 is connected with the end thread of the bullet card frame 8 that plays fastening position mechanism, and axle 12 is installed in the bearing bore 11 through two supplementary bearings 10; Bushing pipe 17 is threadedly connected on the axle 12 through liner adapter 14; Clip spring seat 18 is connected on the end of bushing pipe 17, and jump ring 19 is installed in the clip spring seat 18, clip spring seat 18 under the effect of hitch with the interior step maintenance predetermined gap of outer drill bit 15; In drive pipe 14 and be placed in outside bushing pipe 17 and the liner adapter 14, and with the two matched in clearance, in drive pipe 14 and be connected with the end thread of bearing bore 11; In being connected in, drives on interior drill bit 20 pipe 14 end, and protruding through outer drill bit 15.
The two moving boring principles of three pipes of cord coring drill according to the invention are: when creeping into, face of land rotary system drives drilling rod and rotates, and then outer pipe assembly is rotated, because of inner tube assembly is close on the inwall of bullet card chamber through playing fastening position mechanism and hitch; So, the 13 rotating whiles of outer tube, will drive inner tube assembly and rotate; Since in drive the end that pipe 14 directly is threaded in bearing bore 11, therefore, in drive pipe 14 and will be rotarily formed two moving with outer tube 13; Bushing pipe 17 is threadedly connected on the axle, not with outer tube 13 revolutions, so; It is two moving to form three pipes, at this, constitutes not revolving body by bushing pipe 17, clip spring seat 18 and jump ring 19.Like this, when creeping into fragmentation, no consolidated formation, three layers of pipe of two drill bits mechanism realizes the interior leading two drill bit rotary drillings of drill bit, has both protected rock core not receive the drilling fluid erosion, and the input of round trip inner tube assembly puts in place can to prevent the rock of drill bit formation outside to hinder down when stifled again.
This bullet fastening position mechanism can adopt conventional single card structure that plays; But the double elastic-clip structure below preferred the employing; Be specially: this bullet fastening position mechanism comprises recovery tube 4, bullet card frame 8, goes up bullet card 6 and following bullet card 9; Wherein, the lance seat 3 that drags for of hinge type spearhead mechanism is located in recovery tube 4 through slotted hole and the straight pin that is provided with on it, makes the two that relative displacement can take place in slotted hole range; Have that separate through midfeather portion and last bullet card exterior chamber and following bullet card chamber in the bullet card frame 8; Last bullet card 6 is articulated in respectively in bullet card chamber and the following bullet card chamber with following bullet card 9, and wherein, the bullet card arm of last bullet card 6 is that basic point upwards is provided with its pin joint; The bullet card arm of following bullet card 9 is that basic point is provided with downwards with its pin joint; Be connected with tension spring 5a and following tension spring 5b between two bullet card arms of last bullet card 6 and following bullet card 9 respectively, upper and lower bullet card can be protruding through upper and lower bullet card chamber respectively under the effect of upper and lower tension spring respectively, in addition; The midfeather portion of this bullet card frame 8 is located in recovery tube 7 through slotted hole and the straight pin that is provided with on it; Make between the two and can relative displacement take place in slotted hole range, wherein, last bullet card chamber places in the recovery tube 7; And bullet card chamber places outside the recovery tube 7 down, and this recovery tube 7 is provided with the outwardly directed through hole of bullet card arm of keeping supplying bullet card 6.Has the interior step 23 that when bullet card bullet 9 is opened down, supports its bullet card arm on the inwall of this bullet card chamber 7; The interior step of this time bullet card 9 and bullet card chamber 7 has constituted above-mentioned hitch; Therefore; Adopt the bullet fastening position mechanism of this kind structure, just need not to adopt the hanging ring and the seat ring suspension inner tube assembly of usual use.
In addition; This upper and lower bullet card chamber can be respectively in abutting connection with the position of midfeather portion be provided with all through straight pin be fixed in the bullet card frame on play deck 21 and play deck 22 down; Be respectively arranged with arc surface on the upper and lower bullet deck with radiuses such as upper and lower bullet card ends; Like this, upper and lower bullet be stuck in bullet card frame through bearing pin hinged after, only can rotate along the arc surface of upper and lower bullet deck.Upper and lower bullet deck can make the processing of bullet card frame unlikely too complicated and difficult.
In transferring the process of inner tube assembly, upper and lower bullet card all outwards flicks in getting into the bullet card chamber of internal diameter greater than the internal diameter of bullet block head, and respectively through string on the interior step limits inner tube assembly that plays block head 2 and bullet card chamber 7 and following string.
The purpose of above-mentioned slotted hole setting is: when salvaging drilling tool; On the power of lifting to carry recovery tube up; In the scope of activities of slotted hole; Recovery tube forces the bullet card inwardly to reclaim, and no longer is limited by the step of being formed after the lower surface that plays block head 2 is threaded with bullet card chamber 7, so that whole inner tube assembly is proposed.
In addition, this hinge type spearhead mechanism can adopt the existing hinged mechanism that drags for spearhead 1 and drag for lance seat 3 that comprises, the present invention no longer is described further it at this.
Moreover; Can be provided with on the interior step of this bullet card chamber 7 one be used to stir down the bullet card arm of bullet card shift fork; Though; Since upper and lower bullet card can be respectively under the effect of upper and lower tension spring and the inwall of bullet card chamber 7 be close to, and then can turn round, but stir down the bullet card and can guarantee the servo-actuated property more than the inner tube assembly axle through shift fork is set with outer pipe assembly.
Cord coring drill of the present invention is when creeping into complete stratum; Only need be as shown in Figure 3, drive pipe, bushing pipe and interior drill bit in the removal, will be threadedly connected on the axle through liner adapter 16 with the interior pipe of bushing pipe same size; Can realize that conventional wire line coring creeps into, improve drilling efficiency.At this, constitute not revolving body by interior pipe, clip spring seat 19 and jump ring 18.
The above is merely preferred implementation of the present invention, is not to be used for limiting practical range of the present invention, and the equivalence of in protection scope of the present invention, being done in every case changes and modifies, and all should think to have fallen in protection scope of the present invention.
