The well head that the utility model embodiment provides draws the mechanical device for sending oil pipe, includes support by the way that manipulator 1 is arranged
Portion 101 and the oil pipe control claw 102 being connected on support portion 101 and hanging ring control claw 103, convenient for passing through support portion 101 by machine
Tool hand 1 is connect with mechanical arm 2, and the tube body of oil pipe is clamped using oil pipe control claw 102, is clamped using hanging ring control claw 103
The ontology of hanging ring；It is connect with manipulator 1 by the front end of mechanical arm 2, rear end is inserted into mechanical arm housing 3, and after mechanical arm 2
End is configured as being suitable for moving forward and backward in mechanical arm housing 3, to which the length for making mechanical arm 2 enter mechanical arm housing 3 increases
Or reduce；When in use, the rear end of mechanical arm housing 3 oil pipe drawing is fixed on to send in the special-purpose supporting frame of machine front end.It is rising
When oil pipe, the rear end of control machinery arm 2 moves backward in mechanical arm housing 3, so that manipulator 1 is moved backward, and then make oil pipe
Oil pipe is clamped in control claw 102, and mechanical arm 2 continues to move backward, and moves oil tube external thread end to oil pipe and draws the jigger sent on machine
It is interior；Then, the rear end of control machinery arm 2 travels forward in mechanical arm housing 3, make mechanical arm 2 stretch out, manipulator 1 immediately from
Oil pipe is opened, origin-location is returned to；When oil pipe is soon laid flat, the rear end of control machinery arm 2 is transported backward in mechanical arm housing 3
It is dynamic, so that manipulator 1 is moved backward again, the ontology of hanging ring is clamped in two hanging ring control claws 103, and manipulator 1 pulls girth of rings
Dynamic elevator draws the front end for sending machine close to oil pipe, and after tubing coupling end is positioned on oil pipe pillow, remote control opens elevator, puts down
Oil pipe.In the tripping in oil pipe into oil well, the rear end of control machinery arm 2 moves backward in mechanical arm housing 3, makes manipulator 1
It moves backward, manipulator 1 is clamped girth of rings and moves the coupling end that elevator send oil pipe on machine slideway close to oil pipe drawing, when elevator catches oil
Guan Hou, hook block sling oil pipe；At the same time, the rear end of control machinery arm 2 travels forward in mechanical arm housing 3, makes machine
Tool hand 1 moves forward, and returns to origin-location；When oil pipe soon reaches vertical state, the rear end of control machinery arm 2 is in mechanical arm
It is moved backward in housing 3, manipulator 1 is made to move backward again, oil pipe control claw 102 catches the tube body lower part of oil pipe；Then,
The rear end of control machinery arm 2 travels forward in mechanical arm housing 3, and manipulator 1 is made to move forward, and manipulator 1 is clamped outside oil pipe
The end of thread moves on to well head center, and centering is completed with well oil pipe coupling end.The well provided due to the utility model embodiment
It mouthful draws and to send the mechanical device of oil pipe when being installed to oil pipe drawing and sending in the special-purpose supporting frame of machine front end, oil pipe control claw 102 and hang
Ring control claw 103 extends back from support portion 101, in the flowline from oil well or the lower drain line into oil well, is not necessarily to
Oil pipe drawing send machine, well head and workover rig point-blank, can according to the space arrangement in well site, to workover rig derrick before arbitrary institute
Demander send oil pipe to drawing, therefore the scope of application is wider；And the manipulator 1 of the mechanical device is highly mobile at 2.5 meters or so, no
Shaft mouth operation is carried out to operating personnel to interfere.
The movement in mechanical arm housing 3 for the ease of control machinery arm 2, as shown in Figure 1, being provided in mechanical arm housing 3
