Portion, the diameter of forced section is greater than the diameter of the body of rod, and one end of the body of rod and forced section are integrally formed, also, the other end of the body of rod
It is provided with screw thread, and since the middle position of suspension box cupling 120 is provided with screw thread, it is achieved that the body of rod and suspension box cupling 120
Screw thread it is indirect.It should be noted that the diameter due to forced section is greater than the diameter of the body of rod, so can be loaded on using crane
The junction of forced section and the body of rod, and apply upward power, realize the effect for lifting sucker rod.
Further, after lifting sucker rod, elevator can be removed, and hanger 110 is installed on to the well of pumpingh well
Mouthful, it, by tightening hanger 110, is consolidating for first hanger 110 that the well head of pumpingh well provided in this embodiment, which is provided with screw thread,
It is fixed.
After hanger 110 is fixed, support division 113 is internally provided with due to hanger 110, so can will hang
Box cupling 120 is installed at the support division 113 of hanger 110, and is supported stress by 113 pairs of suspension box cuplings 120 of support division and realized branch
Support, also, connect due to hanging box cupling 120 with connecting rod 130, and connecting rod 130 is connect with sucker rod, to realize oil pumping
The suspension of bar, it is not necessary that sucker rod is lost in Dynamical characteristic, so that when staff needs to carry out again to hang and takes out operation, Neng Gougeng
Add and easily connects the relevant devices such as wellhead polish rod, packing box and double ram type preventer and improve work to reduce workload
Make efficiency.
Further, after it will hang box cupling 120 and be placed in hanger 110, dismountable connecting rod 130, and in hanger
110 end silk plug is installed, wherein the inner wall of the separate first connecting portion 111 of second connecting portion 112 is provided with screw thread, and second
Interconnecting piece 112 is threadedly coupled with silk plug, to realize sealing for equipment.
It should be noted that due to it is provided in this embodiment do envelope work other devices of Dynamical characteristic are not changed
Into having saved cost and easier for installation there is no need to reappear production relevant device.
