Description

Geological core drilling is cored with striking heart device
Technical field
The utility model relates to drilling field, refers to that a kind of geological core drilling is cored with striking heart device especially.
Background technology
In geological core drilling, generally adopt the mode of wire line coring.Wire line coring method is as follows: be connected to the outer basket of drill bit and the inner tube holding rock core, utilize spring detent to lock, also can throw off separation.Creeping into after certain drilling depth is no more than inner tube length, termination of pumping stops boring, in drilling rod, fisher is entered with seizing wire from ground, reach the fishing head catching inner tube at the bottom of hole, then disengagement bayonet lock is carried on, inside and outside basket is separated, in drilling rod, inner tube is mentioned ground, rock core is taken out.
After ground mentioned by inner tube, because rock core can expand, can not come off from inner tube voluntarily.Existing mode beats inner tube with rubber hammer, by vibration, rock core come off from inner tube.But because inner tube wall thickness is less, particularly thin-walled drilling tool inner tube wall thickness only has 2mm, is easy to cause inner tube to be out of shape by the mode that rubber hammer beats, once distortion is serious, inner tube will be caused to scrap.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of geological core drilling and cores with striking heart device, can ensure that inner tube is indeformable in the process of coring, and relatively simply from inner tube, takes off rock core smoothly.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of geological core drilling is cored with striking heart device, and comprise annular housing, described enclosure interior matched in clearance is provided with the connector for connecting inner tube;
Described connector is annular connector, and one end of described annular connector is provided with the syndeton be connected with inner tube.
Further, side and the described connector corresponding section of described housing are provided with screwed hole, are provided with bolt in described screwed hole.
Further, described connector lateral surface is being provided with circular groove with screwed hole opposite position.
Further, described screwed hole and bolt are two and are oppositely arranged on the both sides of described housing.
Further, described syndeton is the internal thread being arranged on described connector end.
Further, the inside of described housing is provided with connector limited impression.
Further, the length of described housing is 10-20cm.
Further, the gap between described annular housing and connector is 0.2-0.8mm.
Further, described housing and connector all adopt steel manufacture.
In use, inner tube is inserted in annular housing, inner tube is inserted in annular housing, after utilizing the syndeton connection inner tube of connector, annular housing is knocked with striking heart hammer, make to produce vibration between itself and connector, vibrate inner tube simultaneously, rock core is come off from inner tube.
The utility model has following beneficial effect:
Geological core drilling of the present utility model is cored with striking heart device; by knocking mode removal of core from inner tube of annular housing band follower link and inner tube vibration; therefore, it is possible to be formed with the protection of effect to inner tube, avoid rubber hammer in prior art and directly knock the problem making it be out of shape on inner tube.
Accompanying drawing explanation
Fig. 1 is that the utility model geological core drilling is cored with the front cross-sectional structural representation striking heart device;
Fig. 2 is that the utility model geological core drilling is cored and looked up structural representation by a kind of embodiment of striking heart device.
Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of geological core drilling to core with striking heart device, as shown in Figure 1, comprises annular housing 1, and housing 1 internal clearance is equipped with the connector 2 for connecting inner tube;
Wherein connector 2 can realize in the following manner:
As shown in Figure 2, connector is annular connector 2, and there is the syndeton for being connected with inner tube one end of connector 2;
In use, inner tube is inserted in annular housing 1, after utilizing the syndeton connection inner tube of connector 2, annular housing 1 is knocked with striking heart hammer, make to produce between itself and connector 2 to vibrate, vibrate inner tube simultaneously, rock core is come off from inner tube.
Mode removal of core from inner tube that the utility model vibrates with follower link 2 and inner tube by knocking annular housing 1; therefore, it is possible to be formed with the protection of effect to inner tube, avoid rubber hammer in prior art and directly knock the problem making it be out of shape on inner tube.
Improve as one of the present utility model, as shown in Figure 1-2, side and connector 2 corresponding section of housing 1 are provided with screwed hole 3, are provided with bolt 4 in screwed hole 3.
When connector is annular connector 2, connector 2 can be fixed in housing 1 by this bolt 4 easily, limits its position in housing 1 simultaneously.
As further improvement of the utility model, described connector 2 lateral surface, is being provided with a bit of circular groove 6 with screwed hole 3 opposite position.
By being provided with segment arc groove 6 at described connector 2 lateral surface corresponding with screwed hole 3, the limited bolt 4 of connector 2 can be made to limit, preventing from rotating and axial float.
Preferably, screwed hole 3 and bolt 4 are two and are oppositely arranged on the both sides of housing 1.
Improve as another kind of the present utility model, when connector 2 is annular connector 2a, the syndeton of connector 2 end is preferably arranged on the internal thread of connector end, matches with the external screw thread of inner tube end to facilitate.
Certainly, other various structures that this syndeton can also adopt those skilled in the art easily to expect, as annular slot etc., as long as can conveniently fix and take off inner tube and do not cause damage to inner tube.
Improve as another kind of the present utility model, as shown in Figure 1, the inside of housing 1 can be provided with connector limited impression 5, and this connector limited impression 5 can increase the stability of connector 2 in housing 1, avoid connector 2 to slide in housing 1, better guarantee effect of coring.
In the utility model, the length of housing 1 is preferably 10-20cm, the gap between housing 1 and connector 2 is preferably 0.2-0.8mm, more preferably 0.5mm, and housing 1 and connector 2 preferably all adopt steel manufacture.
In sum, the utility model has following beneficial effect:
Geological core drilling of the present utility model is cored with striking after heart device is connected with inner tube; core with striking heart device by knocking geological core drilling of the present utility model; indirect drive inner tube vibration, reaches the object of effective protection inner tube in the process of coring.In addition, the utility model is in use simple to operate, easy for installation; Less demanding simultaneously to cost and material in manufacturing process.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
