Abstract
The utility model relates to an electric opening and closing mechanism for a flow-rate measuring and regulating apparatus, which mainly solves the defects that the existing opening and closing mechanism for a measuring and regulating apparatus requires a closing sleeve at the time of opening and closing, so the success rate of the opening and closing is lower. The utility model is characterized in that the mechanism also comprises a transversal cone gear (1) and a longitudinal cone gear (2) which are mutually engaged with vertical directions of rotation, a spring (3), a kinking post (5) and a drawing wire (6), wherein the kinking post (5) and the longitudinal cone gear (2) are coaxial; the drawing wire (6) is kinked on the kinking post; the lower end of the drawing wire (6) is connected with a butt-joint arm of the measuring and regulating apparatus with the spring (3) by an upright shaft of which the direction is changed. The utility model has the characteristics of no need of matching the opening and closing sleeve when a layering pipe column is put down, flexible and free opening and closing and high successful rate.
Description
Technical field:
The utility model relates to a kind of conciliation mechanism that is applied on the downhole measurement adjusting instrument of oil field, especially relates to a kind ofly being used to control docking arm on the measurement and adjustment instrument and to the electric retractable mechanism of extend neck folding and unfolding.
Background technology:
In oil recovery field, oil field, flow metering and adjusting apparatus is that the eccentric separate layer water injection string in oil field is carried out flow rate test and the requisite instrument of allotment, wherein radially open and regain docking arm on the measurement and adjustment instrument and extend neck is mainly finished by jack, existing jack is to carry measurement and adjustment instrument on leaning on, make rotation lock shift fork and injection well downhole flow regulator or folding and unfolding cover collision open retaining mechanism, under the radial spring effect, open docking arm and extend neck.Its detailed process is: carry on when shrinking that measurement and adjustment instrument makes docking arm and extend neck is entered in the folding and unfolding cover, electric rotating machine rotates helical axis thereupon, and pull rope is wrapped on the helical axis, drags to pull docking arm and extend neck is recovered in the measurement and adjustment instrument.Under this structure, owing to open and withdrawal needs the folding and unfolding cover, therefore cause the folding and unfolding success rate lower, and the folding and unfolding cover need be lowered to when lower tubular column, because its internal diameter is little, usually limited the use of other downhole instrument.
The utility model content:
In order to overcome existing measurement and adjustment instrument jack owing to when opening and regain, need recovery set thereby cause the lower deficiency of folding and unfolding success rate, the utility model provides a kind of flow metering and adjusting apparatus electric retractable mechanism, this kind flow metering and adjusting apparatus electric retractable mechanism has folding and unfolding flexibly, freely, the success rate height is equipped with the characteristics that folding and unfolding is overlapped when not needing the lower leaf tubing string.
The technical solution of the utility model is: this kind flow metering and adjusting apparatus electric retractable mechanism, mainly by motor and by motor-operated two intermesh, horizontal conical gear that direction of rotation is perpendicular and vertical conical gear, and spring, kinking post and backguy.Wherein therefore the kinking post can be wound with a backguy with vertical conical gear co-rotation with vertically conical gear is coaxial on the kinking post, and the lower end of backguy links to each other with the measurement and adjustment instrument docking arm that back-moving spring is installed through the vertical shaft that changes direction.
The utlity model has following beneficial effect: because the flow metering and adjusting apparatus electric retractable mechanism that takes such scheme is when finishing the work of regaining and ejecting with docking arm with to extend neck, it is forward and reverse rotation by the control motor, drive two orthogonal conical gear rotations, under the tension that reels line on the extension kinking cylinder of the conical gear that is wound in vertical rotation and under the elastic force effect of spring, make docking arm and extend neck is retracted or ejects, thus the butt joint of docking arm control on having realized measurement and adjustment instrument under the situation of not using the folding and unfolding cover.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The horizontal conical gear of 1-among the figure, the vertical conical gear of 2-, 3-spring, 4-be to extend neck, 5-kinking post, 6-backguy.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this kind flow metering and adjusting apparatus electric retractable mechanism, mainly by motor and two are intermeshed, direction of rotation is perpendicular horizontal conical gear 1 and vertical conical gear 2, and spring 3, kinking post 5 and backguy 6 constitute, wherein coaxial with vertical conical gear 2, also can be seen as the extension line of axle on vertical conical gear 2, backguy 6 is wrapped on the kinking post 5, the lower end of backguy 6 links to each other with the measurement and adjustment instrument docking arm that spring 2 is installed through the vertical shaft that changes direction, extend neck 4 is positioned at the end of docking arm.
During actual the use, ejecting docking arm is undertaken by following process: at first under the control of external world's control power supply, the motor reverse rotation, drive horizontal conical gear 1 and do rotation in the same way, because vertically conical gear 2 is with laterally conical gear 1 is perpendicular, to laterally rotate and become vertical rotation, vertically extension kinking post 5 reverse rotations of the conical gear 2 of rotation, discharge backguy 6, the docking arm that is built-in with extend neck 4 is ejected by the elastic force effect of spring 3, and backguy 6 simultaneously is drawn out under the elastic force effect of spring 3; When regaining docking arm, under the control of external world's control power supply, motor is rotated in the forward, drive horizontal conical gear 1 and do rotation in the same way, thereby the line 6 that reels on the extension kinking post 5 that is wrapped in vertical conical gear 2 is retracted, overcome the elastic force that comes from spring 3 gradually by the pulling force that is brought in this backguy 6, docking arm is regained the most at last.
Utilize the electric retractable mechanism described in the technical program, can do not use finish measurement and adjustment instrument under the situation of folding and unfolding cover on the butt joint control of docking arm, therefore make its had folding and unfolding flexibly, the high characteristics of butt joint success rate.
Claims (1)
1, a kind of flow metering and adjusting apparatus electric retractable mechanism, comprise motor, it is characterized in that: described mechanism also comprise two intermesh, horizontal conical gear (1) that direction of rotation is perpendicular and vertical conical gear (2), and spring (3), kinking post (5) and backguy (6), wherein kinking post (5) is with vertically conical gear (2) is coaxial, be wound with backguy (6) on it, the lower end of backguy (6) links to each other with the measurement and adjustment instrument docking arm that spring (3) is installed through the vertical shaft that changes direction.
