Description
Technical field
Rising for de- sucker rod of breaking the present invention relates to oil well operation equipment, more particularly in a kind of oil pipe unloads connector.
Background technology
The present invention relates to oil fields in oil well operation work progress, and beam hanger is disconnected to be taken off in pipe, is risen when oil pipe is dismantled due to disconnected
De- sucker rod is limited (18 meters of conventional derrick height) in oil pipe, by derrick height cannot smoothly play out the oil pipe at disconnected de- position
And sucker rod.
In the past in routine work work progress, after rod parting, due to breaking, de- sucker rod can not rise in oil pipe
Flowline.Tool is unloaded without special and generally two methods is used to handle in scene：
1. shank diameter of pumping is smaller, draws sucker rod with coir rope, presses sucker rod with the weight of oil pipe and hook, make sucker rod
It is bent, sucker rod is blocked after being extracted out in oil pipe upper pumping rod clip or with going out sucker rod rod elevator.
2. when shank diameter of pumping is big, sawed-off sucker rod, then sucker rod is pulled out out of oil pipe, then block upper pumping rod fasterner
Son acts sucker rod.
The two methods operate at the scene to be had the following disadvantages in application：
1, operational hazards security risk is big, and safety accident easily occurs.2, it acts the sucker rod and can not reuse and cause not
Necessary economic loss.3, operation is laborious and inconvenient, and staff labor intensity is big.4, work rate is low, influences construction speed.

Description of the drawings
It, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical solution in the prior art
Embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In all the appended drawings, similar element
Or part is generally identified by similar reference numeral.In attached drawing, each element or part might not be drawn according to actual ratio.
Disconnected de- sucker rod acts the structural schematic diagram for unloading connector in the oil pipe that Fig. 1 provides for an embodiment；
Fig. 2 is the A-A sectional views of the second semicanal in Fig. 1.
Specific implementation mode
The embodiment of technical solution of the present invention is described in detail below in conjunction with attached drawing.Following embodiment is only used for
Clearly illustrate technical scheme of the present invention, therefore be only used as example, and the protection model of the present invention cannot be limited with this
It encloses.
It should be noted that unless otherwise indicated, technical term or scientific terminology used in this application should be this hair
The ordinary meaning that bright one of ordinary skill in the art are understood.
Referring to Figures 1 and 2, rising for de- sucker rod of breaking in an embodiment, in oil pipe provided by the invention unloads connector, by axis
100 and second semicanal 200 of symmetrically arranged first semicanal forms, and the first semicanal 100 and the second semicanal 200 are by being arranged half
Flange 4 outside pipe connects, and flange 4 is both provided in the top and bottom of semicanal.100 and second semicanal of above-mentioned first semicanal
Rising for 200 compositions unloads connector and includes：It is located at the first attachment device of 1 upper end of ontology and is located at the of 1 lower end of the ontology
Two attachment devices, first attachment device are used for connected pipes, and second attachment device is used for when oil pipe is transferred, automatically
Connecting with pumping rod.
Break de- sucker rod in oil pipe provided in this embodiment acts that unload connector operation principle as follows：Oil pipe is inserted into first
In connecting tube 2, the bolt on the first semicanal 100 and 200 flange 4 of the second semicanal is locked, to reduce the hole of the first connecting tube 2
Diameter holds oil pipe tightly.Oil pipe to be transferred, automatic hold tightly is taken off disconnected sucker rod by the second attachment device, by above carrying oil pipe, to
Sucker rod is risen.
In the present embodiment, first attachment device is the first connecting tube 2, and inner wall is equipped with first for holding oil pipe tightly
Card tooth prevents oil pipe and the first connecting tube in lifting process to increase the frictional force between 2 inner wall of the first connecting tube and oil pipe
2 disengage.
In order to be convenient for changing after the damage of the first card tooth, the first connecting tube 2 is detachably connected with ontology 1, specifically, first
Connecting tube 2 is set in the inner wall for the tube body to form ontology 1, and is connect with ontology 1 by screw 8.
Specifically, second attachment device includes the second connecting tube being connect with ontology 1 and setting second connection
The automatic cohesion device of inside pipe wall.The automatic cohesion device includes multiple armful being evenly arranged around second connecting tube axle center
Tight part；Each the holding part includes：Be axially arranged on the slideway 9 of the second connection inside pipe wall, be slidably arranged in it is described
Sliding block 3 on slideway 9 and the return unit being connect with the sliding block 3；The slideway 9 tilts close, institute to axle center from top to bottom
It includes the resetting spring 7 for being connected to 3 upper end of sliding block and the limit spring 6 for being connected to 3 lower end of sliding block, limit spring 6 to state return unit
The other end be resisted against on spring retainer piece 5.Act that unload connector downward when the de- sucker rod that breaks in oil pipe provided in this embodiment
When mobile, sucker rod jacks up sliding block 3 upwards, while sliding block 3 is moved along slideway 9 far from axle center, to increase the formation of multiple sliding blocks 3
Snap ring aperture, oil pipe is inserted into snap ring, and under the action of return unit, sliding block 3 is resisted against on sucker rod.Connection is unloaded when rising
When device is lifted up with oil pipe, opposite second connecting tube slide downward under the action of frictional force of sliding block 3, to be leaned on to axle center
Closely, the aperture for reducing snap ring improves pressure of the sliding block 3 to sucker rod, further increases between sliding block 3 and sucker rod
Frictional force, to lift sucker rod.
Similarly, in order to increase the frictional force between sliding block 3 and sucker rod, the sliding block 3 is equipped with close to the one end in axle center and uses
In the second card tooth for holding sucker rod tightly.
Rising for de- sucker rod of breaking in the oil pipe of offer is originally provided and unloads connector simple operation, safe and reliable, elimination
The de- sucker rod that breaks in oil pipe acts the security risk unloaded, and reduces labor intensity, while the sucker rod avoided out scraps.
