Description
Technical field
The present invention relates to a kind of core bit, more particularly, to a kind of governor motion for core bit.
Background technology
As geological prospecting construction depth is constantly deepened, the drilling process more and more higher of bad ground is skidded for hard
The problem of construction on stratum is in the urgent need to address, therefore, rope percussion drilling technique are more and more widely used, the work
Skill is the construction technology for being combined wire line core drilling technology with hydraulical impact drilling technology, former by rotary-percussive drilling
Reason, carries out coring again after smashing into particle by firm hard formation or be powdered.
The length of pipe assembly inside and outside core bit, is mainly adjusted by adjusting joint and adjusting nut.Reach card bullet
Spring abutment bottom and the gap (3-4mm) required by step in drill bit, reduce core by washer meeting.In use, due to
The change of inner tube element size, the gap of clip spring seat and step in drill bit also changes therewith.In order to ensure recorery,
Residual core is reduced, therefore should be adjusted in time.
At present, the existing governor motion for core bit haves the shortcomings that complicated, cost is high and regulation is inconvenient.
The content of the invention
It is an object of the invention to provide a kind of governor motion for core bit, it has simple in construction, cost low
The characteristics of with regulation is easy to, it is used for the above mentioned problem that the governor motion of core bit is present to solve prior art.
For up to this purpose, the present invention uses following technical scheme：
A kind of governor motion for core bit, it includes center-pole, alarm valve block, bearing block and interior pipe cap, described
One end of center-pole is provided between several alarm valve blocks, two neighboring alarm valve block by self-locking nut and is provided with adjusting pad
Piece, the bearing block is arranged on the center-pole, and thrust bearing is provided with the center-pole of described bearing block one end, described to stop
Pipe cap, the center-pole in adjust pad, the other end connection of the bearing block are set between thrust bearing and the alarm valve block
On be provided with drop-hanger bearing and compression spring in said inner tube cap, the compression spring is sheathed on institute by locking nut
State on center-pole.
Especially, said inner tube cap is connected on the bearing block by helicitic texture.
Especially, lock washer is installed on the outside of the locking nut on the center-pole.
Especially, one end of the compression spring is resisted against on the drop-hanger bearing, and the other end is spacing by locking nut.
Beneficial effects of the present invention are that not only structure is simple for the governor motion for core bit compared with prior art
It is single, it is easy to accomplish；It is easy to adjust and manufacturing cost is low.
Brief description of the drawings
Fig. 1 is the structural representation for the governor motion 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 the governor motion for core bit that the specific embodiment of the invention 1 is provided
Structural representation.
In the present embodiment, a kind of governor motion for core bit includes center-pole 1, alarm valve block 2, the and of bearing block 3
Interior pipe cap 4, one end of the center-pole 1 is provided between two alarm valve blocks 2, two alarm valve blocks 2 by self-locking nut 5 to be set
Adjust pad 6 is equipped with, the bearing block 3 is arranged on the center-pole 1, is provided with the center-pole 1 of described one end of bearing block 3
Thrust bearing 7, sets adjust pad 6 between the thrust bearing 7 and the alarm valve block 2, the other end of the bearing block 3 leads to
Cross and be threaded with interior pipe cap 4.
The drop-hanger bearing 8 and compression spring 9 being provided with the center-pole 1 in said inner tube cap 4, the compression bullet
One end of spring 9 is resisted against on the drop-hanger bearing 8, and the other end is fixed on the center-pole 1 by locking nut 10.
Lock washer 11 is installed in the outside of the locking nut 10 on the center-pole 1.
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.
