The specific embodiment
Embodiment with reference to accompanying drawing 1, is equipped with bracing frame 33 in the central tube 8 of multi-functional extension hanger, the bracing frame 33 peripheral equipments pawl spring 3 of giving up, the pawl spring 3 belows dress of the giving up support set 32 of giving up, the dress pistons 31 of giving up in the support set 32 of giving up.Giving up connects top connection 1 outside pawl spring 3 upper ends, connects positioning sleeve 34 outside top connection 1 below and is equipped with tightly with being equipped with cap 2, is equipped with cap 2 peripheral equipment sand prevention leather cups 35.At the peripheral equipment fishing head 5 of pawl spring 3 of giving up, cylinder sleeve 4 on fishing head 5 peripheral equipments.Dress adapter sleeve 6 between central tube 8 and the fishing head 5, adapter sleeve 6 outer dress deblocking pawl springs 7 are used stop pin 9 positioning and fixing between deblocking pawl spring 7 and the last cylinder sleeve 4.Between central tube 8 and last cylinder sleeve 4 lower ends, load onto cone 10, upper cone 10 tops dress buffering packing element 30.Load cone 15 outside central tube 8 middle parts, lower cone 15 external application upper press rings 16 are pushed down, and are installed watts 13 between upper cone 10 and lower cone 15, dress cylindroid helical-coil compression springs 14 in the middle of the slips 13, be installed watt cover 12 and to be equipped with cap 11 with slips fixing of slips 13 two ends.Dress packing element axle 17 is adorned three road packing elements 19 outside the packing element axle 17 below central tube 8 peripheries, upper press ring 16, dress spacer ring 20 between the packing element 19, and packing element 19 peripheral equipment protection rings 18, pressure ring 22 and fixing with pin 21 is loaded in packing element 19 belows.Central tube 8 outer, following pressure ring 22 belows dress main pistons 23, support set 24 is established in main piston 23 lower ends, and pins with lock dog 25, lock dog 25 lower ends dress auxiliary piston 26, auxiliary piston 26 usefulness lock rings 27 are fixing, load cylinder sleeve 28 outside main piston 23 and auxiliary piston 26, and following cylinder sleeve 28 usefulness snaps 29 are fixing.
The course of work of multi-functional extension hanger is: set: suppress to the water filling of instrument inner chamber, when pressure reaches 6-8Mpa, auxiliary piston 26 is descending, main piston 23 is up, continue to suppress to 25Mpa, it is up that main piston 23 drives 17 continuation of packing element axle, compression packing element 19, lower cone 15 continues up, till supporting slips 13 fully.The screw thread of following cylinder sleeve 28 external surfaces and snap 30 progressively lock packing element 19 and lower cone 15 in the up process of support set 25, finish setting.
Deblocking, 1, continue water filling and suppress to 30Mpa, the piston 31 of giving up is up, and after the shear pin of giving up was cut off, the piston 31 of giving up entered the inner chamber of the pawl spring 3 of giving up, and continued to suppress the pawl spring 3 of giving up is directly broken away from adapter sleeve 6, realized that deblocking moves; 2, stop water filling and suppress, directly positive rotation top connection 1 some circles are released from the screw thread of adapter sleeve 6 until the screw thread of the pawl spring 3 of giving up, and directly the upper lifting pipe post is realized the deblocking action.
