Abstract
The invention particularly provides an efficient salvage device which solves the problems that in an existing drilling construction process, a drill rod is prone to twisting and breaking, so that a drill hole is scrapped, production efficiency is low and the economical losses are larger are solved. The efficient salvage device comprises a core barrel. The core barrel is internally provided with a spiral drilling slip. The inner wall of the core barrel is provided with inner spiral grooves matched with the drilling slip. Gaps are formed between the spiral faces of the drilling slip and the inner spiral grooves. The lower end of the drilling slip is fixedly provided with a guide key. The lower end of the core barrel is provided with a clamping sleeve, and the clamping sleeve is fixedly provided with a strip-shaped clamping key tightly attached to the guide key. The efficient salvage device is reasonable and reliable in structural design, the drilling efficiency is improved, the amount of labor is reduced, certain amount of material consumption is reduced for a mine, using defects of an anti-wire connector, a male coupling tap and a female coupling tap are overcome, the drill rod and drill bit can be taken out and can be reused, the efficient salvage device is good in universality, waste is reduced, and the cost is saved.
Description
Technical field
The present invention relates to underground coal mine drill bit, drilling rod fishing device, be specially a kind of efficient fisher.
Background technology
Along with coal production technology constantly advances, and the objective requirement of safety driving, each driving face must first visit rear pick, to guarantee to accomplish to shoot the arrow at the target.When drilling in colliery; construct various boring, the degree of depth and the quality requirement of probing are more and more higher, cause in practice of construction; due to objective and subjective reason; often there will be that drill bit is lost at the bottom of hand-hole, drilling rod twists off and falls into the medium accident in hole, thus causes boring to scrap, drill bit drilling rod is lost; consume a large amount of labour hour; add and certain creep into expense, consume boring tool, cause unnecessary loss.
Summary of the invention
The present invention causing in order to drilling rod when solving existing drilling construction easily twists off that boring is scrapped, production efficiency underground and the larger problem of economic loss, provides a kind of efficient fisher.
The present invention adopts following technical scheme to realize: efficient fisher, comprise basket, helical form drilling slip is provided with in basket, basket inwall has the inner spiral groove coordinated with drilling slip, and leave gap between the helicoid of drilling slip and inner spiral groove, drilling slip lower end is fixed with feather key, and basket lower end is provided with cutting ferrule, cutting ferrule is fixed with the strip card key being close to feather key.
During operation, when drilling rod enters after in basket, as long as apply an axial compression, drilling slip is up in basket, because axial compression makes drilling rod enter drilling slip, now up the and diameter of drilling slip swells, and uses its hard sharp steel tooth to borrow the effect of elastic force that drilling rod is bitten clamping; When on carry time, drilling slip relatively moves downward in basket, and because itself and inner spiral groove leave gap, so drilling slip reduced, drilling rod is by more firm by what grab; When drilling rod salvaged upper after, release drilling rod time, after taking off cutting ferrule, rotary drilling slips, can exit from drilling rod.When overcoming existing drilling construction drilling rod easily twist off and causing that boring is scrapped, production efficiency underground and the larger problem of economic loss.
Reasonable in design of the present invention is reliable, improve punching operating efficiency, and reduce the amount of labour used, for mine reduces the material consumption of certain number, compensate for the familiar lacunas of anti-Threaded Connector Coupling and die nipple, female coupling tap, and the drilling rod of taking-up can be made, drill bit reuses, universal performance is good, decrease waste, save cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-basket, 2-drilling slip, 3-inner spiral groove, 4-feather key, 5-cutting ferrule, 6-strip card key.
Detailed description of the invention
Efficient fisher, comprise basket 1, helical form drilling slip 2 is provided with in basket 1, basket 1 inwall has the inner spiral groove 3 coordinated with drilling slip 2, and leave gap between the helicoid of drilling slip 2 and inner spiral groove 3, drilling slip 2 lower end is fixed with feather key 4, and basket 1 lower end is provided with cutting ferrule 5, cutting ferrule 5 is fixed with the strip card key 6 being close to feather key 4.
In specific implementation process, when carrying out operation to the drilling rod of different size, the drilling slip of different size is selected to realize.
