Description
Technical field
The utility model belongs to field of tool.
Background technology
When oil extraction in oil field, needing many sucker rods, sucker rod is when installing/dismounting, and general employing two ways is carried out,
One is to use novel installing/dismounting machinery to install or remove, although this kind of machinery operating efficiency height is laborsaving, but itself
Huge and heavy, typically more convenient when batch installs or removes, during once individual well single replacing occur, just sensation is a little
Waste, so, just using the second way when general individual well is single, common wrench is manually changed, and now common wrench is just
If operating very loaded down with trivial details, and waste time and energy.Additionally, due to having sand, wax etc. or downhole oil tube rod modification in well, make
Becoming sucker rod stuck, the strength of people cannot use common spanner to rotate sucker rod.
Content of the invention
The purpose of this utility model is that design is a kind of at the floated liquid carrying out carrying out on a small scale installing or removing sucker rod
Pressure power spanner.
The utility model is clamped with gear wheel, and gear wheel center by limiting roll and position limited gear in wrench body
Wrench body on the fixed cover in the same center of circle with gear wheel is installed, gear wheel inwall is installed with reducing sliding
Groove, expansion link tail end withstands on reducing chute, and the other end passes through fixed cover, and guide gear engages with position limited gear, driving gear
Engaging with guide gear, limiting roll, position limited gear, guide gear are all arranged in wrench body by respective axis, actively
Gear is by being arranged in wrench body with the prolongation axis removing tooth；The beam hanger making beam hanger square toes stretch into is had in wrench body
Gathering sill, and all have the corresponding gap with gathering sill at gear wheel and fixed cover；Wrench body tail end is trigger piece.
Expansion link of the present utility model is two, is all vertically installed with pole, pole lower end and worm screw under every expansion link
Engagement, on worm screw, the snail line on corresponding two poles of difference is contrary, and worm screw one end is connected on motor.
The utility model simple in construction, easy for operation.Due to by the series of gears theory of engagement by rod grip
Labor, is thus made more firm being clamped of sucker rod, then is firmly installed sucker rod easily by the arm of force principle of spanner
Or dismantle convenient.

Detailed description of the invention
The utility model is clamped with gear wheel 13, gear wheel 13 by limiting roll 3 and position limited gear 6 in wrench body 1
Being substantially and being suspended between limiting roll 3 and position limited gear 6, the chucking power of dependence limiting roll 3 and position limited gear 6 is clamped, gear wheel
The fixed cover 12 in the same center of circle with gear wheel 13 is installed in the wrench body 1 at 13 centers, fixing on gear wheel 13 inwall
Being provided with reducing chute 5, reducing chute 5 is gradually increased from inside to outside, and expansion link 4 tail end withstands on reducing chute 5, and the other end is worn
Crossing fixed cover 12, it is flexible that such expansion link 4 tail end can carry out back and forth when moving along reducing chute 5, guide gear 7 with
Position limited gear 6 engages, and driving gear 8 engages with guide gear 7, and limiting roll the 3rd, position limited gear the 6th, guide gear 7 is all by each
Axis be arranged in wrench body 1, such limiting roll the 3rd, position limited gear the 6th, guide gear 7 is all carried out only in respective axle
Rotating, driving gear 8 is by being arranged on the prolongation axis 10 removing tooth in wrench body 1, with the prolongation axis 10 removing tooth
The not axis of still driving gear 8, can also remove tooth by spanner occlusion and rotate, thus drive driving gear 8 to revolve
Turn, and prolongation axis 10 axle that tooth removed by band is connected in wrench body 1；Have in wrench body 1 and make beam hanger square toes 11 stretch into
Beam hanger gathering sill 2, and all have the corresponding gap with gathering sill 2 at gear wheel 13 and fixed cover 12；Wrench body 1 tail end is
Trigger piece 9.
The course of work:
First it, by the square toes 11 of sucker rod in beam hanger gathering sill 2, is placed between expansion link 4, then passes through common wrench
Rotating band removes the prolongation axis 10 of tooth, drives driving gear 8 to rotate simultaneously, due to the theory of engagement between gear, drives successively
Guide gear the 7th, position limited gear 6 rotates, in the final position driving gear wheel 13 to limit between limiting roll 3 and position limited gear 6
Rotate, drive reducing chute 5 to rotate simultaneously, owing to the internal diameter of reducing chute 5 is different, thus promote expansion link 4 to carry out
Indentation, owing to using two relative expansion links 4, such two expansion links just move closer to, and clamp square toes 11,
Now locking driving gear 8, simultaneous retractable bar 4 has reached the flexible limit, it is impossible to carry out indentation again, thus by rod grip
Live.
Expansion link 4 of the present utility model is two, is all vertically installed with pole 16, pole 16 lower end under every expansion link 4
Engaging with worm screw 14, on worm screw 14, the snail line on corresponding two poles 16 of difference is contrary, and worm screw 14 one end is connected on motor 15.
Due to independent the sliding in reducing chute 5 of expansion link 4, easily deviate from, be thus likely to cause unsafe factor, so,
Pole 16 is set under expansion link 4, and by the worm screw 14 contrary with two ends snail line expansion link 4 carried out power-assisted and
Support.So-called snail line refers to that the snail line on worm screw 14 both sides is contrary spiral on the contrary, thus drives two expansion links 4 worm screw 14
Drive and lower form simultaneously inside or simultaneously outside being synchronized with the movement.
When workover treatment rod job, suspended type hydraulic power operated wrench advances rod collar position, safety
Door is closed, pull operation control valve, and spanner rotates, and backup tong pins next root sucker rod simultaneously, makes the normal shackle of sucker rod, works as liquid
After pressure spanner shackle finishes, pulling out spanner, safety door is closed.Reciprocation cycle, has served bar effect.During lower sucker rod, reversely
Operational control valve, makes to detain on sucker rod.
Having sand, wax etc. due in well, causing sucker rod stuck, the strength of people cannot rotate sucker rod, and hydraulic power is pulled
Hand output power is big, and smooth running can unfreezing easily.
Due to downhole oil tube rod modification, in pumping rod fasterner dead oil pipe, it is necessary to when having overlapped sucker rod, manpower cannot operate, liquid
Pressure power spanner can easily overlap back-off.
1st, this product uses medium carbon steel to cast, and there is oil leab at gear shaft center, and gear ring uses four bearings to protect tooth, it is ensured that
Service life of product.
2nd, suspended type hydraulic power operated wrench have employed hydraulic transmission mode makes spanner rotate, and output power can reach 3000 Ns
, reach to remove operation to sucker rod.
What the 3rd, this product was applicable to sucker rod during oil field well workover treatment plays bar, lower beam, unfreezing, back-off etc., will
Manpower was moved box spanner actuating oil-pumping unit button and was changed into mechanical-hydraulic power actuating oil-pumping unit in the past, decreases manpower, alleviates
Working strength, accelerates job schedule simultaneously, improves well workover quality.
4th, this product has that volume is little, power big, noiselessness, and simple to operate, durable in use, service life is long, and safety is anti-
Protect measure complete.
5th, this product is through many experiments, improves, and has reached at present, easy to use, simple to operate, volume is little, lightweight,
Dynamic property is strong, safe and reliable.In front of the door domestic also there is no oil field well workover treatment during similar product that sucker rod is made a trip
Product.
