In figure: 1, coring base 101, connecting portion 102, installation portion 2, female coupling tap 3, corer 4, core drill
Head.
Detailed description of the invention
Fig. 1 is most preferred embodiment of the present utility model, and 1 pair of this utility model is described further below in conjunction with the accompanying drawings.
A kind of deep hole drill fishing device, including the female coupling tap 2 on corer 3 and corer 3 and coring bit 4, female coupling tap 2
Being coaxially mounted in the upper end of corer 3, coring bit 4 is coaxially mounted to the bottom of corer 3, the endoporus of coring bit 4 and
The endoporus of corer 3 is all higher than the external diameter of burying drilling tool, and the length of corer 3 is more than or equal to the length of burying drilling tool.This
The corer 3 of deep hole drill fishing device and coring bit 4 by the way of cleaning bottom of hole under in hand-hole so that burying drilling tool is whole
Entering in corer 3, female coupling tap 2 entangles drilling tool tail end, thus realizes the salvaging of burying drilling tool, applied widely, and to burying
The damage of drilling tool is little, salvages drilling tool success rate height, simplifies exception handles, convenient transportation.
Concrete: as shown in Figure 1: corer 3 is round steel pipe, the length of corer 3, more than the length of burying drilling tool, takes
The internal diameter of core pipe 3 is slightly larger than the length of burying drilling tool such that it is able to enables burying drilling tool completely in corer 3, improves
The success rate that burying drilling tool is salvaged.
Coring bit 4 is arranged on the lower end of corer 3, and coring bit 4 is cylindric, and the internal diameter of coring bit 4 is more than taking
The external diameter of core pipe 3, the lower end outer wall of corer 3 is provided with screw thread, and the inwall of coring bit 4 is provided with and matches with corer 3 lower end
Screw thread, the lower end of corer 3 puts in coring bit 4 endoporus, and is fixed by screw thread and coring bit 4 and be connected.
The upper end of corer 3 is provided with coring base 1, is the cylinder that diameter is equal with corer 3 external diameter in the middle part of coring base 1
Shape, the top of coring base 1 is the connecting portion 101 for being connected with rig, and bottom is the peace being connected with corer 3 and female coupling tap 2
Dress portion 102.
The diameter of connecting portion 101 is less than the diameter in the middle part of coring base 1, and connecting portion 101 is provided with for rig even
The screw thread connect, so that coring base 1 can directly be connected with rig, easy to connect.
Installation portion 102 is annular, and the external diameter of installation portion 102 is slightly smaller than the internal diameter of corer 3, and the internal diameter of installation portion 102 is slightly
External diameter more than female coupling tap 2 top.The outer wall of installation portion 102 and inwall are equipped with screw thread, and the upper end inwall of corer 3 is provided with and pacifies
The screw thread that dress portion 102 matches, the outer wall top of female coupling tap 2 also is provided with the screw thread matched with installation portion 102, the top of female coupling tap 2
Being connected in putting in installation portion 102 and by screw thread is fixing with installation portion 102, installation portion 102 is put in coring by the upper end of corer 3
It is connected in pipe 3 and by screw thread is fixing with corer 3.
The work process of this deep hole drill fishing device is as follows: coring bit 4 rotates under the drive of rig, thus former
Put down borehole wall on the basis of having boring, and original boring is carried out reaming, simultaneously by the effect of dredge pump water under high pressure
Hole is rinsed well, reduces the resistance of boring.Length according to burying drilling tool determines the length of corer 3 used, and will take
Core drill bit 4 and corer 3 use under the mode of cleaning bottom of hole in hand-hole, then install coring base 1, female coupling tap 2 in the upper end of corer 3,
Connect.Use the mode sweeping sky to throw abort situation into, slow down rate of penetration, allow burying drilling tool enter in corer 3,
Ensureing output, in observation port, coal dust rinses situation simultaneously, until burying drilling tool fully enters in corer 3, and uses female coupling tap 2
Entangling burying drilling tool tail end, then start punching repeatedly, in treating hole, coal dust washes down, and can normally pull out of hole, and completes drilling tool and salvages.
The above, be only preferred embodiment of the present utility model, is not that this utility model is made other form
