Abstract
The present invention relates to the anti kickback attachment of a kind of screw pump sucker rods, including pawl disk, ratchet, torsion spring, ratchet and anchor ear；Described pawl disk is provided with the ratchet of multiple circular array distribution；It is provided with torsion spring between described ratchet and pawl disk；Described pawl disk side is provided with ratchet；Described ratchet is provided with groove, and when pawl disk rotates counterclockwise, ratchet withstands in the groove of ratchet；Described ratchet is connected with anchor ear；Brake film it is additionally provided with between described ratchet and anchor ear, the anti kickback attachment of the screw pump sucker rods of the present invention, its simple in construction, during driving means reversion, by ratchet in the groove of ratchet so that pawl disk cannot move, thus play the effect to preventing sucker rod reversing, simultaneously can the moment of torsion of manual release sucker rod, it is ensured that the safety of workman, there is preferable practical value.
Description
Technical field
The present invention relates to a kind of anti kickback attachment, particularly relate to a kind of anti kickback attachment for screw pump sucker rods.
Background technology
Screw pump oil production is, by sucker rod, the power that ground drives is passed to underground rotor, and sucker rod fills with driving
Putting connected, wherein sucker rod must rotate forward, and inverted sucker rod can cause and trip；But find when actually used, when
When well head driving means quits work, the sucker rod release moment of torsion of nearly km, can cause sucker rod reversion to thread off, the most not only endanger
And the life security of oil field workman, and the tremendous economic of stopping production can be caused to lose.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art to provide one can prevent sucker rod from inverting, and can be manual
The anti kickback attachment of the screw pump sucker rods of release sucker rod moment of torsion.
For reaching above-mentioned purpose, the technical solution used in the present invention is: the anti kickback attachment of a kind of screw pump sucker rods, bag
Include pawl disk, ratchet, torsion spring, ratchet and anchor ear；Described pawl disk is provided with the ratchet of multiple circular array distribution；Described ratchet
And it is provided with torsion spring between pawl disk；Described pawl disk side is provided with ratchet；Described ratchet is provided with groove, and pawl disk is counterclockwise
During rotation, ratchet withstands in the groove of ratchet；Described ratchet is connected with anchor ear.
Preferably, brake film it is additionally provided with between described ratchet and anchor ear.
Preferably, described anchor ear is formed by connecting by locking screw screw bolt and nut by two half anchor ears being symmetrically set.
Preferably, the quantity of described ratchet is two.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The anti kickback attachment of the screw pump sucker rods of the present invention program, its simple in construction, during driving means reversion, existed by ratchet
In the groove of ratchet so that pawl disk cannot move, thus play the effect to preventing sucker rod reversing, can manual release take out simultaneously
The moment of torsion of beam hanger, it is ensured that the safety of workman, has preferable practical value.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further.
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is to omit the structural representation of the present invention after anchor ear and brake film.
Accompanying drawing 3 is the structural representation that anchor ear is connected with brake film.
Wherein: 1, pawl disk；2, ratchet；3, torsion spring；4, ratchet；5, anchor ear；6, groove；7, brake film.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
Be the anti kickback attachment of a kind of screw pump sucker rods of the present invention as illustrated in the accompanying drawings from 1 to 3, including pawl disk 1,
Ratchet 2, torsion spring 3, ratchet 4 and anchor ear 5；Described pawl disk 1 is provided with the ratchet 2 of multiple circular array distribution；Described ratchet 2 with
Torsion spring 3 it is provided with between pawl disk 1；Described pawl disk 1 side is provided with ratchet 4；Described ratchet 4 is provided with groove 6, and pawl disk is inverse
When hour hands rotate, ratchet 2 withstands in the groove 6 of ratchet 4；Described ratchet 4 is connected with anchor ear 5；Between described ratchet 4 and anchor ear 5
It is additionally provided with brake film 7；Described anchor ear 5 connected by locking screw screw bolt and nut by two half anchor ears being symmetrically set and
Become；The quantity of described ratchet 2 is two.
Operation principle is as described below: being first arranged on the fixing circular shaft of driving means by ratchet, anchor ear is fixed on driving
On the casing of device, ratchet is arranged on pawl disk, and pawl disk can be rotated by driving means；Anchor ear lock during work
Tightly, ratchet does clockwise rotation along with pawl disk, when needs stop, pawl disk stop motion, ratchet rely on torsion spring to
Centre is drawn close, and when pawl disk has the trend of counterclockwise movement, ratchet withstands in the groove of ratchet, stops pawl disk to be transported counterclockwise
Dynamic, serve the effect to preventing sucker rod reversing.
When needs release moment of torsion, only the locking nut of anchor ear upper end need to be unclamped to appropriate location, by the strength of spring
Separately anchor ear, moment of torsion just can slowly discharge, again lock after release.
The anti kickback attachment of the screw pump sucker rods of the present invention program, its simple in construction, during driving means reversion, pass through spine
Pawl is in the groove of ratchet so that pawl disk cannot move, thus plays the effect to preventing sucker rod reversing, can manually release simultaneously
Put the moment of torsion of sucker rod, it is ensured that the safety of workman, there is preferable practical value.
Below it is only the concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employings
The technical scheme that equivalents or equivalence are replaced and formed, within the scope of all falling within rights protection of the present invention.
