The specific embodiment
Be described in detail of the present utility model below in conjunction with drawings and Examples.
The utility model is sent into the pipe nipple device by installing at upper part of riser pipe, and drill string passes a bearing and is lowered into riser pipe inside.Rotation by drill string afterwards bears against the butterfly of support steel bar bottom and the butterfly on the short drill pipe mutually, and then produces moment of torsion, and the pipe nipple device is sent in drive and drill string rotates synchronously.When rotation synchronously, send into the pipe nipple device and riser pipe fixedly becomes one, play and stablize the double action that riser pipe and top are set upright by fixing screw thread realization.
As shown in Figure 1 and Figure 2, upper part of riser pipe of the present utility model is sent into the pipe nipple device and is comprised: centre bearing 1, angle steel 2, support steel bar 3 and last butterfly 4.Wherein, centre bearing 1 is positioned at upper part of riser pipe and sends into pipe nipple device centre, short drill pipe 5 and drill string 6 pass from the centre of centre bearing 1, and centre bearing 1 does not rotate with the rotation of drill string 6, thereby riser pipe 7 does not rotate with the rotation of drill string 6 yet.Short drill pipe 5 and drill string 6 can move by easy on and off simultaneously, thereby guarantee normally creeping into of drill string 6, and the internal diameter size of centre bearing 1 needs the external diameter greater than short drill pipe 5 and drill string 6.
Angle steel 2 is made up of vertical steel plate 21 and horizontal steel plate 22, and vertical steel plate 21 and horizontal steel plate 22 are " 7 " font setting.The arranged outside of vertical steel plate 21 and the fixedly screw thread 23 that riser pipe 7 is complementary can be fixed with riser pipe 7.Laterally steel plate 22 can be placed on the plane, top of riser pipe 7, plays the effect of stablizing riser pipe 7.A plurality of angle steel 2 evenly distribute, and form a circumference in the upper inner of riser pipe 7.
Support the inboard that steel bar 3 one ends are welded on vertical steel plate 21, the other end is welded on the outer surface of centre bearing 1, is used for that centre bearing 1 is fixed on upper part of riser pipe and sends into pipe nipple device centre.Support steel bar 3 bottoms and install butterfly 4, with the following butterfly 8 supporting settings that are arranged on the short drill pipe 5.When the installation upper part of riser pipe was sent into the pipe nipple device, last butterfly 4 and following butterfly 8 bore against mutually, produced moment of torsion by drill string 5 forwards and reverse rotation, and the realization upper part of riser pipe is sent into the automatic installation and removal of pipe nipple device.
As shown in Figure 3, Figure 4, short drill pipe 5 of the present utility model comprises butterfly 8, female joint 9, main body 10 and male joint 11 down.Following butterfly 8 is arranged on the relevant position at main body 10 middle parts.
Among the embodiment of the present utility model, the number of angle steel 2 is 4, and in the inboard circular layout of riser pipe 7, angle is 90 ° between adjacent two angle steel 2.The number of last butterfly 4 and following butterfly 8 is consistent with the number of angle steel 2.The thickness of last butterfly 4 and the consistency of thickness that supports steel bar 3, length are about 1/3 of support steel bar 3.The length of short drill pipe 5 is about 50cm, the size of the following butterfly 8 on it and last butterfly 4 couplings.
Upper part of riser pipe of the present utility model is sent into the pipe nipple Unit Installation and demounting procedure comprises:
1, upper part of riser pipe is sent into the pipe nipple Unit Installation:
1) short drill pipe 5 is inserted in the drill string assembly.
