According to the hook, during work, the hook and a valve body are in face contact, stress is uniform, slippage is not prone to happening, use is convenient, maintenance is easy, drawing operation is in place at a time, work efficiency can be obviously improved, and safety is greatly improved.
Description
Technical field
The present invention relates to hydraulic draw valve device technical field, particularly relate to a kind of hydraulic draw valve device special
Hook.
Background technology
Hydraulic draw valve device belongs to cementing equipment and fracturing complete sets of equipment, is mainly used in various deep-well
Drilling well, well workover, well cementation, water blockoff, water injection work and slurry conveyed, clay, mortar etc. are situated between
Matter, the hook that traditional hydraulic draw valve device uses is the most backward, drawing strength during pulling out valve
Little, the phenomenon of " drawing motionless " in field operation easily occurs, and easily produces sliding,
Accidents caused, security performance is relatively low.The Chinese invention patent of Publication No. 203650441U is public
Having driven a kind of hydraulic draw valve device, wherein said coupler body and be the hook of hydraulic draw valve device, it leads to
Crossing bearing pin transmission strength, pulling capacity is too small, it is impossible to the taking-up being applicable to high pressure drilling pump valve seat is made
Industry.
Summary of the invention
The invention aims to solve shortcoming present in prior art, and the one proposed
Hydraulic draw valve device dedicated hook.
To achieve these goals, present invention employs following technical scheme:
A kind of hydraulic draw valve device dedicated hook, including hanger bulk, described hanger bulk includes the end
Seat, adapter sleeve, groove and inclined-plane, the cross section of described base is elliptical shape, described base and
Being equipped with cylindric through hole on the inwall of adapter sleeve, the side outer wall of described adapter sleeve is provided with recessed
Groove, the bottom of described base is provided with inclined-plane near the side of groove.
Preferably, the horizontal line relative to adapter sleeve of the adapter sleeve inwall below groove it is positioned at described in
In a certain angle, described in be positioned at cylindric relative to base of the base inner wall of reverse side, inclined-plane
Through hole central axis is in a certain angle, and described inclined-plane is certain folder relative to the horizontal line of base
Angle.
Preferably, the horizontal line relative to adapter sleeve of the adapter sleeve inwall below groove it is positioned at described in
In the inclined-plane of 35 ° of angles, described in be positioned at the inwall of the reverse wing base in inclined-plane relative to base
Cylindric through hole central axis be the inclined-plane of 35 ° of angles, described inclined-plane is relative to base
Horizontal line is 35 ° of angles.
Preferably, described hanger bulk is by the disposable forging molding of round steel.
Preferably, described base, adapter sleeve, groove and fixed block are integrated.
In the present invention, hanger bulk uses round steel heating in medium frequency forging molding, makes the gold of these parts
Phase constitution becomes the most even and closely thus improves plasticity and the mechanical property of these parts,
Hook uses essence forging dies to form, and the follow-up scrap rate in finishing passes is the least, more
The close bed formed when remaining forging, improves the anti-fatigue life dedicated hook structure of parts
Compact, easy to use, safeguard simple, drawing operation one-time-reach-place, work effect can be significantly improved
Rate, and safety obtained greatly promoting.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present invention
Case is clearly and completely described, it is clear that described embodiment is only the present invention one
Divide embodiment rather than whole embodiments.
With reference to Fig. 1-2, a kind of hydraulic draw valve device dedicated hook, including hanger bulk 1, described
Hanger bulk 1 includes base 2, adapter sleeve 3, groove 4 and inclined-plane 5, described base 2
Cross section is elliptical shape, and the inwall of described base 2 and adapter sleeve 3 is equipped with cylindric through hole,
The side outer wall of described adapter sleeve 3 is provided with groove 4, and the bottom of described base 2 is near groove
The side of 4 is provided with inclined-plane 5, described in be positioned at adapter sleeve 3 inwall below groove 4 relative to even
The horizontal line of female connector 3 is 35 ° of angles, described in be positioned at the base 2 of inclined-plane 5 reverse side
Inwall is 35 ° of angles relative to the cylindric through hole central axis of base 2, described inclined-plane 5
It is 35 ° of angles relative to the horizontal line of base.
Invention hook body 1 uses round steel heating in medium frequency forging molding, makes the metallographic of these parts
Tissue becomes the most even and closely thus improves plasticity and the mechanical property of these parts, hangs
Hook uses essence forging dies to form, and the follow-up scrap rate in finishing passes is the least, more protects
The close bed formed when having stayed forging, improves the anti-fatigue life of parts.
Operation principle of the present invention: the through hole on dedicated hook of the present invention is through hydraulic draw valve device
On drawing leading screw, then drawing leading screw is transferred in valve seat orifice, until sinking down under valve seat,
Vertical rotating links up with 35 °, after making leading screw axis and hook notch 4 central axes, allows
Hook freely falling body is transferred, and now hook passes through valve seat orifice and drops down onto leading screw shoulder, natural shape
State lower draw-bar is taken a seat after inverting 35 °, can carry out drawing work, and invention hook changes former
Link up with mode, the face of changing into valve body point cantact to contact, produce pulling capacity and link up with more than tradition,
And it is not likely to produce sliding.Dedicated hook compact conformation of the present invention, easy to use, safeguard simple,
Drawing operation one-time-reach-place, can significantly improve work efficiency, and safety has obtained greatly carrying
Rise.
