Abstract
The invention provides a spiral drill rod fisher. In the prior art, no fisher aiming to a spiral drill rod exists. The spiral drill rod fisher consists of five parts, namely a support ring (1), a reinforcing rib (2), a spiral blade (3), a connecting pipe (4) and an alloy tool head (5), wherein the spiral blade (3) is wound on the connecting pipe (4); the outside diameter of the spiral blade (3) is welded with the reinforcing rib (2); and one end of the reinforcing rib (2) is fixed on the connecting pipe (4), while the other end is fixed on the support ring (1). When drilling accidents are processed, the spiral blade (3) can be screwed in a blade of a hole bottom accident drill rod to realize fishing. The spiral drill rod fisher has the characteristics of simple structure, convenient operation, safety, reliability, reusability and the like, and is suitable for the fishing requirements of various spiral drill rods by changing the dimension of the spiral blade.
Description
Technical field
The present invention relates to the drilling tools class, is the fisher of auger stem in a kind of drilling operation specifically.
Background technology
In the prior art, there is not special fisher for auger stem.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, easy to operate spiral drill rod fisher that has.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of spiral drill rod fisher, its special character is: described fisher comprises support ring 1, reinforcing rib 2 and helical blade 3, takes over 4; Described helical blade 3 is wound on to be taken on 4, is welded with reinforcing rib 2 on the external diameter of helical blade 3, and an end of reinforcing rib 2 is fixed on to be taken on 4, and the other end is fixed on the support ring 1.When processing drilling accident, helical blade 3 can screw in the blade of accident drill rod at the bottom of the hole, realizes salvaging.
Setting has certain drilling ability on above-mentioned support ring 1 cylindrical, assists the alloy cutter head 5 at the bottom of fisher enters the hole.
3 reinforcing ribs 2 evenly are set on the external diameter of above-mentioned helical blade 3.
The above-mentioned helical pitch of taking over the helical blade 3 on 4 that is arranged on is clockwise or counter clockwise direction.
The connected mode of above-mentioned adapter 4 adopts and is threaded or socket connection.
The internal diameter of above-mentioned fisher is greater than the external diameter of auger stem core pipe to be salvaged; The external diameter of fisher is greater than the external diameter of auger stem blade to be salvaged and be less than or equal to bore diameter.
The present invention is as follows with respect to the advantage of prior art: spiral drill rod fisher is simple in structure, easy to operate, and is safe and reliable, can be repeatedly used etc.Can adapt to the salvaging requirement of multiple auger stem by the size that changes helical blade.

Specific embodiment
Referring to Fig. 1, Fig. 2; Screw connected spiral drill rod fisher structure comprises support ring 1, reinforcing rib 2 and helical blade 3, takes over 4; Described helical blade 3 is wound on to be taken on 4, the helical pitch of helical blade 3 is clockwise or counter clockwise direction, consistent with the helical pitch of auger stem blade to be salvaged, 3 reinforcing ribs 2 of uniform welding on the external diameter of helical blade 3, one end of reinforcing rib 2 is fixed on to be taken on 4, and the connected mode of adapter 4 adopts and is threaded, and the other end is fixed on the support ring 1, have certain drilling ability the setting of support ring 1 cylindrical, assist the alloy cutter head 5 at the bottom of fisher enters the hole.The internal diameter of fisher is greater than the external diameter of auger stem core pipe to be salvaged; The external diameter of fisher is greater than the external diameter of auger stem blade to be salvaged and be less than or equal to bore diameter.
When processing drilling accident, helical blade 3 can screw in the blade of accident drill rod at the bottom of the hole, realizes salvaging.
Referring to Fig. 3; Fig. 3 is plug-in type auger stem fisher structural representation; The connected mode of adapter 4 adopts and is threaded or socket connection.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
