Abstract

The utility model discloses an automatic tubing block restorer. The restorer comprises four parts including an automatic restorer, a fixer, a block and a slideway, wherein a wire cable of the automatic restorer is wound on a wire cable winding drum; a pulling end of the wire cable is connected to the block; a flat spiral spring is positioned in the wire cable winding drum, the outer end of the flat spiral spring is fixed onto the inner wall of the wire cable winding drum, and the inner end is coupled with a mandrel; and the fixer consists of a movable tube, a fixed tube, a restorer base, a cross shaft and a locking screw rod. When an oil tube is pulled, the male buckle end of the oil tube placed on the block drives the block to move on the slideway, so that the flat spiral spring gains elastic potential energy and drives the block to return to the original position automatically. The utility model is convenient and fast to disassemble and assemble, saves the trouble that operating personnel have to push the block back and forth, relieves the labor intensity of the operating personnel, promotes wide application of the block, protects the oil tube, and reduces accident potentials in the production.

Description

Oil pipe jigger automatic reset

Technical field the utility model relates to the oil pipe jigger automatic reset that uses in a kind of oil well repairing operation.

Background technology is at present in the oil well repairing operation process, for preventing the wearing and tearing of oil pipe screw thread, the operational procedure regulation: must be placed on oil pipe screw thread one end when removing oil pipe and just can sling on the jigger of slideway or put down oil pipe.But because jigger can not automatically reset, every next root tubing manipulation personnel will come and go nearly 20 meters distance and push jigger and return standby position, and a bite oil well all has hundreds of oil pipes, has increased operating personnel's labour intensity greatly.Therefore, the operating personnel is unwilling to use jigger, execute-in-place all is the directly friction slip on slideway of oil pipe pin end, jigger has become ornaments, operational procedure can not get carrying out, Frictional Slipping badly damaged the oil pipe screw thread, also the ordinary production of oil well is buried potential safety hazard, in case tubing leak or disconnected taking off will be caused major accident.

The summary of the invention the purpose of this utility model is to provide a kind of oil pipe jigger automatic reset, to alleviate well workover field operation personnel's labour intensity, promotes the execution of operating technology rules, thereby the protection oil pipe is eliminated accident potential.

For achieving the above object, the utility model is made of automatic reset, fixator, jigger and slideway four parts.The wire rope of automatic reset is wrapped on the cable drum, and the end that wire rope is pulled out is connected on the jigger.Plane scroll spring is positioned at cable drum, and the outer end is fixed on the cable drum inwall, and the inner end connects with mandrel, and mandrel is fixed on the housing.Fixator is made up of adjustable pipe, stationary pipes, restorer base, transverse axis and tie down screw, stationary pipes and restorer base are fixed on the transverse axis, adjustable pipe one end is enclosed within on the transverse axis, tie down screw traverses fixed pipe and adjustable pipe, stationary pipes will be longer than adjustable pipe, the stationary pipes of fixator and adjustable pipe can be inserted in arbitrary end of slideway, and automatic reset is fixed on the restorer base.

As further improvement of the utility model, the restorer base of fixator can be to be sleeved on the transverse axis, and be screwed.

Adopted after the said structure,, tightened the nut on the tie down screw again, just can be connected into one to fixator and automatic reset with slideway easily as long as the stationary pipes of fixator and adjustable pipe are inserted an end that needs on the slideway.Jigger is placed on the slideway, and the oil pipe pin end is placed on the jigger, when the tubing coupling end is sling or transferred, will drag jigger and move on slideway, wire rope is pulled out and is driven cable drum and rotate, and plane scroll spring tightens, storage elasticity potential energy.After the oil pipe pin end broke away from jigger, plane scroll spring discharged the elastic potential energy that stores, and drove the cable drum backward rotation, wire rope is regained, and the pulling jigger turned back to the origin-location.

When the task that removes changes, as long as unscrew nut on the tie down screw, just can pull down fixator and automatic reset from slideway, and then the other end that is fixed in slideway just can have been proceeded next step operation.

Oil pipe jigger easy accessibility of the present utility model, quick; save the operating personnel and come and gone the trouble that pushes jigger, alleviated operating personnel's labour intensity, can promote the extensive use of jigger; thereby protected oil pipe, and reduced the accident potential in producing.

Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the work schematic diagram of the utility model oil pipe jigger automatic reset.

Fig. 2 is the front view of fixator in the specific embodiment of the utility model oil pipe jigger automatic reset.

Fig. 3 is the sectional view of the automatic reset of the utility model oil pipe jigger automatic reset.

The specific embodiment is as shown in Figure 1: when needs trip out in the well oil pipe, as long as an end of close well head on the stationary pipes 8 of fixator 2 and the adjustable pipe 7 insertion slideways 6, tighten the nut 9 on the tie down screw 3 again, just can be connected into one to fixator 2 and automatic reset 1 with slideway 6 easily.Jigger 5 is placed on slideway 6 one ends near automatic reset 1.After playing flowline, the oil pipe pin end is placed on the jigger 5, when the tubing coupling end is transferred, oil pipe will drag jigger 5 and move to the direction away from well head on slideway 6, cable drum 15 is pulled out and driven to wire rope 16 rotate, plane scroll spring 14 tightens, storage elasticity potential energy.After the oil pipe pin end was carried off from jigger 5, plane scroll spring 14 discharged the elastic potential energy that stores, and drives cable drum 15 backward rotation, wire rope 16 is regained, and pulling jigger 5 turned back to the origin-location.

When under the needs during oil pipe, as long as unscrew nut 9 on the tie down screw 3, just can pull down fixator 2 and automatic reset 1 from slideway 6, and then be fixed on the slideway 6 a end and just can proceed down the oil pipe operation away from well head.

Oil pipe jigger automatic reset easy accessibility of the present utility model, quick; save the operating personnel and come and gone the trouble that pushes jigger, alleviated operating personnel's labour intensity, can promote the extensive use of jigger; thereby protected oil pipe, and reduced the accident potential in producing.
