Abstract
The utility model relates to an inversion -preventing device of spiral shell sucker -rod pumping sucker rod, including pawl dish, pawl, torsional spring, ratchet and staple bolt, be equipped with a plurality of circular array distributed's pawl on the pawl dish, be equipped with the torsional spring between pawl and the pawl dish, pawl dish one side is equipped with the ratchet, be equipped with the recess on the ratchet, and pawl dish rotated counter -clockwise, the pawl pushes up in the recess of ratchet, ratchet and staple bolt link to each other, still be equipped with the brake film between ratchet and the staple bolt, the utility model discloses an inversion -preventing device of spiral shell sucker -rod pumping sucker rod, its simple structure, drive arrangement when reversal, through the pawl in the recess of ratchet for the unable motion of pawl dish, thus play and prevent inverse effect to the sucker rod, but the moment of torsion of manual release sucker rod has simultaneously guaranteed workman's safety to have better practical value.
Description
Technical field
This utility model is related to a kind of anti kickback attachment, more particularly, to a kind of anti-reversing dress for screw pump sucker rods
Put.
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
Put connected, wherein sucker rod must rotate forward, inverted sucker rod can cause to trip；But find when actually used, when
When well head driving means quit work, the sucker rod release moment of torsion of nearly km, can cause sucker rod reversion to thread off, so not only endanger
And the life security of oil field workman, and the huge economic losses stopping production can be caused.
Utility model content
This utility model purpose is to overcome the deficiencies in the prior art to provide one kind can prevent sucker rod from inverting, and can
The anti kickback attachment of the screw pump sucker rods of manual release sucker rod moment of torsion.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of anti-reversing dress of screw pump sucker rods
Put, including pawl disk, ratchet, torsion spring, ratchet and anchor ear；Described pawl disk is provided with the ratchet of multiple circular array distributions；Institute
State and between ratchet and pawl disk, be provided with torsion spring；Described pawl disk side is provided with ratchet；Described ratchet is provided with groove, and pawl disk
When rotating counterclockwise, ratchet withstands in the groove of ratchet；Described ratchet is connected with anchor ear.
Preferably, it is additionally provided with brake film between described ratchet and anchor ear.
Preferably, described anchor ear is formed by connecting by locking screw screw bolt and nut by half anchor ear that two are symmetrically set.
Preferably, the quantity of described ratchet is two.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that this practicality is new
The anti kickback attachment of the screw pump sucker rods of type scheme, its structure is simple, during driving means reversion, recessed in ratchet by ratchet
So that pawl disk cannot move in groove, thus playing the effect that preventing sucker rod is reversed, simultaneously can manual release sucker rod torsion
Square, it is ensured that the safety of workman, has preferable practical value.
Brief description
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further.
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is to omit structural representation of the present utility model 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；2nd, ratchet；3rd, torsion spring；4th, ratchet；5th, anchor ear；6th, groove；7th, brake film.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
It is a kind of anti kickback attachment of screw pump sucker rods described in the utility model as illustrated in the accompanying drawings from 1 to 3, including ratchet
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 distributions；Described spine
It is provided with torsion spring 3 between pawl 2 and pawl disk 1；Described pawl disk 1 side is provided with ratchet 4；Described ratchet 4 is provided with groove 6, and spine
When pawl disk rotates counterclockwise, ratchet 2 withstands in the groove 6 of ratchet 4；Described ratchet 4 is connected with anchor ear 5；Described ratchet 4 and anchor ear
It is additionally provided with brake film 7 between 5；Described anchor ear 5 passes through locking screw screw bolt and nut even by two half anchor ears being symmetrically set
Connect and form；The quantity of described ratchet 2 is two.
Operation principle is as described below: first ratchet is arranged on the fixing circular shaft of driving means, 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 with pawl disk, when need stop when, 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 from being transported counterclockwise
Dynamic, serve the effect that preventing sucker rod is reversed.
When needing to discharge 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, and release is locked after finishing again.
The anti kickback attachment of the screw pump sucker rods of this utility model scheme, its structure is simple, during driving means reversion, leads to
Cross ratchet in the groove of ratchet so that pawl disk cannot move, thus playing the effect that preventing sucker rod is reversed, simultaneously can handss
The moment of torsion of dynamic release sucker rod, it is ensured that the safety of workman, has preferable practical value.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.All employing equivalents or equivalence replacement and the technical scheme that formed, all fall within this utility model rights protection scope it
Interior.
