Abstract
The clamp of the fixing screw is applied to the oil field wellhead Christmas tree. Is characterized in that: the lower semicircular hoop and the upper semicircular hoop are semicircular annular hoops, and the lower semicircular hoop and the upper semicircular hoop are opposite to form a circular ring; the outer sides of the two ends of the lower semicircular hoop and the upper semicircular hoop are respectively provided with a flat plate, and the flat plates at the two ends of the lower semicircular hoop and the upper semicircular hoop are parallel to each other; bolt holes are respectively formed in the flat plates at the two ends of the upper semicircular hoop; bolts are vertically welded on the flat plates at the two ends of the lower semicircular hoop respectively, and the center line of each bolt hole in the flat plates at the two ends of the upper semicircular hoop are the same straight line; the bolt penetrates through bolt holes in flat plates at two ends of the upper semicircular hoop, and a nut is fixed at the end of the bolt. The effect is as follows: can connect on the production tree, need not take reverse rotation-proof measure to the screw rod again during the dismouting, alone can install and remove, reduce the manpower extravagant, improve oil gas well preventer installation rate.
Description
Technical field
The utility model relates to the oil-field well head device technical field, and a kind of Special fixing tool that particularly uses on the well head production tree is the clip of the standing screw of special use on a kind of production tree.
Background technique
At present, production tree is the on-the-spot vital control head of petroleum industry, and groove type clip is to use maximum Placements between each member.It is two lobes, two screw rods, four nuts that the clip that uses at present consists of, and lobe is on semiround body and the two ends wing platform through hole to be arranged, and screw rod passes through hole on the lobe body wing platform is realized clip by screwing nut clamping separately.The advantage that long-term practice manifests is that form is simple, uniform specification, be convenient to batch production; The shortcoming that exposes is fastening with spanner or dismounting during nut, screw rod rotates together in company with nut, must take reverse anti-rotation measure at the screw rod the other end, generally need the above cooperation of two people just can finish, waste of manpower, the operating space is little, cause difficulty to strengthen strength increase when highly low and combination miss increases, and the Oil/gas Well blowout prevention, to highlight shortcoming when robbing spray serious.
The model utility content
The purpose of this utility model is: a kind of clip of standing screw is provided, and the clip of special-purpose standing screw does not need again screw rod to be taked reverse anti-rotation measure on the production tree, and a people can install and remove, and reduces the manpower waste.
The technical solution adopted in the utility model is: the clip of standing screw comprises second circular boop, first circular boop, screw bolt and nut.It is characterized in that: second circular boop and first circular boop are the semicircle circumferential band, ring of second circular boop composition relative to first circular boop; There is respectively flat board in the outside, two ends at second circular boop and first circular boop, and the flat board at second circular boop and first circular boop two ends is parallel to each other; Bolt hole is arranged respectively on the flat board at first circular boop two ends; Be vertically welded with respectively bolt on the flat board at second circular boop two ends, the center line of the bolt hole on the center line of bolt and first circular boop two ends flat board is the same straight line; Bolt passes the bolt hole on first circular boop two ends flat board, is fixed with nut in the end of bolt.
The inner cylindrical surface of described second circular boop and first circular boop has toroidal cavity.
The beneficial effects of the utility model: the clip of the utility model standing screw, can be connected on the production tree, do not need during dismounting again screw rod to be taked reverse anti-rotation measure, a people can install and remove, and reduces the manpower waste, improves Oil/gas Well preventer installation rate.
Description of drawings
Fig. 1 is the yoke configurations generalized section of the utility model standing screw.
Among the figure, second circular boop of 1-, first circular boop of 2-, 3-bolt, 4-nut.
Embodiment
Embodiment 1: take the clip of the standing screw of 120 millimeters of diameters that is applicable to KY21 ∕ 65 production trees as example, the utility model is described in further detail.
Consult Fig. 1.The clip of the utility model standing screw comprises second circular boop 1, first circular boop 2, bolt 3 and nut 4.Second circular boop 1 and first circular boop 2 are the semicircle circumferential band, ring of second circular boop 1 and first circular boop 2 relative compositions.160 millimeters of outside diameters, 80 millimeters of interior circular diameters, 70 millimeters of thickness.There is respectively flat board in the outside, two ends at second circular boop 1 and first circular boop 2, and the flat board at second circular boop 1 and first circular boop 2 two ends is parallel to each other.The bolt hole that 25 millimeters of diameters are arranged respectively on the flat board at first circular boop 2 two ends.On the flat board at second circular boop 1 two ends, be vertically welded with respectively the bolt 3 of M24,80 millimeters of the length of bolt 3.The center line of the bolt hole on the center line of bolt 3 and first circular boop 2 two ends flat boards is the same straight line; Bolt 3 passes the bolt hole on first circular boop 2 two ends flat boards.Be fixed with the nut 4 of M24 in the end of bolt 3.The inner cylindrical surface of second circular boop 1 and first circular boop 2 has toroidal cavity.50 millimeters of the width of groove, 20 millimeters of the degree of depth.
Claims (2)
