Abstract
For core bit lance assembly is dragged for the invention discloses a kind of, it includes dragging for lance seat and drags for spearhead, wherein, described one end for dragging for lance seat offers pin-and-hole, it is connected in recovery tube by resilient key, the other end for dragging for lance seat is hinged with by elasticity volume pin and drags for burr, and it is described drag for lance seat and drag for be provided with positioner between spearhead.The positioner includes locating piece and retaining spring, and one end of the locating piece is touched with the lance seated connection that drags for, and the retaining spring is arranged at the locating piece and described dragged between spearhead.It is above-mentioned for core bit drag for lance assembly in it is described drag for lance seat and drag for set up positioner between spearhead.It is not only simple in structure, it is easy to accomplish；And be easily installed, improve the reliability and stability for dragging for spearhead work.
Description
Technical field
The present invention relates to a kind of core bit, for core bit lance assembly is dragged for more particularly, to a kind of.
Background technology
The characteristics of core bit is, when core fills inner tube, not carry brill and inner tube is dragged for out of drilling rod with rope salvaging device
Take to obtain core.Because its is simple in construction, drilling efficiency is high, rock (ore deposit) core taking rate high, labor intensity is low, drilling cost is low
Deng remarkable advantage, and it is widely used in the fields such as geological prospecting, coal exploration.
Important component that lance assembly is core bit is dragged for, it is necessary to which during coring, fisher transfers to inner tube out of drilling rod
Assembly upper end, recovery hook, which is hooked, drags for spearhead.Fisher is lifted up, spearhead is dragged for and recovery tube is lifted up by spring catch, force
Play clamp to shrink, inner tube assembly is departed from outer pipe assembly, so that inner tube is elevated.
At present, the existing lance assembly that drags for for core bit haves the shortcomings that complicated and installation inconvenience.
The content of the invention
For core bit drag for lance assembly it is an object of the invention to provide a kind of, its have it is simple in construction, be easy to peace
The characteristics of dress and reliable and stable work, to solve the above mentioned problem for dragging for the presence of lance assembly of prior art core bit.
For up to this purpose, the present invention uses following technical scheme：
A kind of to drag for lance assembly for core bit, it includes dragging for lance seat and drags for spearhead, wherein, described one end for dragging for lance seat
Pin-and-hole is offered, it is connected in recovery tube by resilient key, the other end for dragging for lance seat is hinged with by elasticity volume pin and dragged for
Burr, and it is described drag for lance seat and drag for be provided with positioner between spearhead.
Especially, the positioner includes locating piece and retaining spring, and lance seat is dragged in one end of the locating piece with described
Contact, the retaining spring is arranged at the locating piece and described dragged between spearhead.
Especially, the end for dragging for lance seat offers " V " type groove, and the end of the locating piece is " V " type described in cooperation
The pyramidal structure of groove.
Especially, locating slot is offered in the locating piece, one end of the retaining spring is installed in the locating slot.
Beneficial effects of the present invention are that the lance assembly that drags for for core bit drags for lance in described compared with prior art
Seat and drag for and set up positioner between spearhead.It is not only simple in structure, it is easy to accomplish；And be easily installed, improve and drag for spearhead work
The reliability and stability of work.
Brief description of the drawings
Fig. 1 is the structural representation for dragging for lance assembly for core bit that the specific embodiment of the invention 1 is provided.
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1, Fig. 1 is that the core bit that is used for that the specific embodiment of the invention 1 is provided drags for lance assembly
Structural representation.
It is a kind of to drag for lance assembly including dragging for lance seat 1 and dragging for spearhead 2 for core bit in the present embodiment, it is described to drag for lance seat 1
One end offer pin-and-hole 3, it is connected in recovery tube by resilient key, it is described drag for lance seat 1 the other end pass through elasticity volume pin 4
Be hinged with and drag for burr 2, and it is described drag for lance seat 1 and drag for positioner is provided between spearhead 2, the positioner includes locating piece
5 and retaining spring 6, the end for dragging for lance seat 1 offers " V " type groove 7, the end of the locating piece 5 " V " type described in coordinating
The pyramidal structure of groove 7.
Locating slot 8 is offered in the locating piece 5, one end of the retaining spring 6 is installed in the locating slot 8.
The structure design of above-mentioned positioner, can be easy to drag for the installation of lance assembly, spearhead is dragged for while can greatly improve
The reliability and stability of work.
Above example is the general principle and characteristic for elaborating the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and change, and these changes and modifications are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
