Description
Technical field
The utility model relates to a kind of control device that is used for oil and gas wells in oil fields, particularly a kind of tubing collar detection device that is applicable to Operating Pressure.
Background technology
The main device of Operating Pressure is annular preventer or ram preventer, and it deforms under the control of hydraulic coupling, thereby holds the oil pipe in the well tightly, realizes the sealing to well head.Because the box cupling diameter of oil pipe greater than caliber, by force by preventer the time, can cause friction to tear to annular rubber core, makes the shortening in application life of glue core, increases cost of production, reduces operating efficiency.The effect of tubing collar detection device is, when tubing coupling during near preventer, sends and reports to the police or control signal, make preventer fast, open, to guarantee passing through smoothly of tubing coupling in good time.The tubing collar detection device that uses is generally induction at present, not only structure is comparatively complicated, uses inconvenience, and owing to be subjected to the influence of factors such as the greasy dirt of the instantaneous unstability of outside power frequency supply and working site and metal material, make detecting error bigger, reliability is lower.
The utility model content
For overcoming the deficiencies in the prior art part, the utility model provide a kind of rational in infrastructure, result of detection is accurate, the tubing collar detection device of easy to operate, high efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the half-closed type ram preventer, described half-closed type ram preventer comprises body, guard shield, leading screw and flashboard; The main latus rectum both sides of body are established and are provided with the flashboard die cavity symmetrically, and two flashboards are sub-packed in the above-mentioned two flashboard die cavities, in the outside of flashboard die cavity guard shield and pressure cap are housed successively; The inner of leading screw places in the above-mentioned flashboard die cavity, and control crank and locking nut are equipped with in its outer end; It is characterized in that: on leading screw the inner transmission nut is housed, the outside of transmission nut is equipped with fairlead, and the outer end of fairlead is provided with the boss that is placed in the transmission nut outer end; The inner of fairlead links to each other with flashboard; Be provided with tooth bar on flashboard, the gear on this rack and pinion axle is meshed; Induction wheel also is housed on gear shaft.
It axially offers gathering sill in the outer peripheral face upper edge of above-mentioned fairlead, is provided with the feather key that is fixed on the transmission nut in gathering sill.
The beneficial effects of the utility model are: it is rational in infrastructure, and is easy to operate, and result of detection is accurate, has avoided the damage of tubing coupling to preventer, has improved the operating efficiency of Operating Pressure greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1 for locking nut, 2 for control crank, 3 for pressure cap, 4 for guard shield, 5 for leading screw, 6 for body, 7 for flashboard, 8 be main latus rectum, 9 for oil pipe, 10 for box cupling survey wheel, 11 for gear shaft, 12 for gear, 13 for tooth bar, 14 for spring, 15 for fairlead, 16 for transmission nut, 17 for gathering sill, 18 for feather key, 19 for induction wheel, 20 be box cupling.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Tubing collar detection device described in the utility model comprises half-closed type ram preventer, box cupling detection wheel 10, gear shaft 11 and induction wheel 19.Described half-closed type ram preventer comprises body 6, guard shield 4, leading screw 5 and flashboard 7; Main latus rectum 8 both sides of body 6 are established and are provided with the flashboard die cavity symmetrically, and two flashboards 7 are sub-packed in the above-mentioned two flashboard die cavities, in the outside of flashboard die cavity guard shield 4 and pressure cap 3 are housed successively; The inner of leading screw 5 places in the above-mentioned flashboard die cavity, and control crank 2 and locking nut 1 are equipped with in its outer end; On leading screw 5 the inners transmission nut 16 is housed, the outside of transmission nut 16 is equipped with fairlead 15, and the outer end of fairlead 15 is provided with the boss that is placed in transmission nut 16 outer ends, makes fairlead 15 spacing; The inner of fairlead 15 links to each other with flashboard 7; It axially offers gathering sill 17 in the outer peripheral face upper edge of above-mentioned fairlead 15, is provided with the feather key 18 that is fixed on the transmission nut 16 in gathering sill 17.On flashboard 7, be provided with tooth bar 13; Above tooth bar 13, be provided be horizontally disposed with, run through body 6 and with the perpendicular gear shaft 11 of leading screw 5; Above-mentioned tooth bar 13 is meshed with gear 12 on the gear shaft 11; On a side outer end of gear shaft 11, induction wheel 19 is housed also.
During work, at first the utility model is installed between the upper and lower annular preventer of well device, rotate control crank 2 then, make the central motion of transmission nut 16 to main latus rectum 8, fairlead 15 drives flashboard 7 under the effect of spring 14 and box cupling is surveyed wheel 10 also to the central motion of main latus rectum 8, surveys wheel until box cupling and contacts with the surface of oil pipe 9; And induction wheel 19 is connected with the alarm that other establishes.When the box cupling 20 of oil pipe 9 contacts with box cupling detection wheel 10, box cupling is surveyed wheel 10 under box cupling 20 effects of oil pipe 9, overcome the active force of spring 14, driving flashboard 7 outwards moves, tooth bar on the flashboard 7 13 gear shaft 11 are rotated simultaneously, thereby make induction wheel 19 drive alarm work, open upward (or down) annular preventer of closed condition, the box cupling 20 of oil pipe 9 passes through smoothly, thereby avoided the flashboard collision of box cupling 20 with the preventer of oil pipe 9, improved the security performance and the operating efficiency of operation.
