This oil-well rig is as follows with drilling rod conveyer operating principle:
One, send load to rig floor 1
Referring to Fig. 6, this device send load to the rig floor 1 concrete course of work to be:
1,＜1 〉, device is parked in the pipe racking chord position and puts, drilling rod 4 drilling tools such as grade are moved on the drilling rod conveyer, front end lifting motor 15 and rear end lifting motor 14 running counterclockwise simultaneously then, front end hoisting system 17, rear end hoisting system 12 and tooth bar guide rail 5 constitute a parallel-crank mechanism, and this process can guarantee that tooth bar guide rail 5 is parallel to upwards rising of ground;
2,＜2 〉, device rises to rear end hoisting system 12 when perpendicular to the ground, and locked rear end hoisting system 12 limits its rotation clockwise and counterclockwise both direction, does not also drive and front end hoisting system 17 is locked, can freely rotate;
3,＜3 〉, rear end hydraulic cylinder 13 certain height that hoists that hoists then, this process front end hoisting system 17 can clockwise rotate a low-angle, tooth bar guide rail 5 no longer is parallel to ground, but individual inclination angle is arranged, drilling rod 4 is because the gravity of itself will produce one to the trend of lower slider like this, this process mainly advances for auxiliary horizontal sliding piece 8, the situation that load is little, this process of making the angle of slope can not carried out, start horizontal sliding piece drive motors 9 then, drive horizontal sliding piece 8 and travel forward at tooth bar guide rail 5, push drilling rod 4 to rig floor 1 reposefully;
4,＜4 〉, under workman's assistance, grasp drilling rod 4 front ends by manipulator 2, and upwards promote, these process drilling rod 4 bodys have broken away from back-up block 3, and just the rear end also travels forward on horizontal sliding piece 8 thereupon, be lifted fully until drilling rod 4, the rear end breaks away from horizontal sliding piece 8.
Two, unloaded backhaul
When finishing drilling tool and transmitting the unloaded backhaul in back: the rear end hydraulic cylinder 13 that hoists shrinks, the piece of horizontal sliding simultaneously 8 retreats into the rear end initial position of tooth bar guide rail 5, this moment, end stone 10 can effectively limit the displacement of horizontal sliding piece 8, the normal steady operation of assurance device, front end lifting motor 15 and rear end lifting motor 14 turn clockwise simultaneously then, tooth bar guide rail 5 is down to the pipe racking frame, gets ready for transmit next time.
Three, load backhaul
Drilling tool on the rig floor 1 is transported to pipe racking frame or ground when being the load backhaul: rear end hydraulic cylinder 13 backhauls that hoist, tooth bar guide rail 5 is parallel to ground, the workman assists the rear end with drilling rod 4 to be aided with other instruments to be fixed on the horizontal sliding piece 8, manipulator 2 is transferred in the process and is moved behind the horizontal sliding piece 8 then, place fully on horizontal sliding piece 8 and the back-up block 3 until drilling rod, according to magnitude of load, whether to need to determine the front end hydraulic cylinder 16 that hoists to rise and make the auxiliary horizontal sliding piece 8 in angle of inclination and promote drilling rods, just move behind the horizontal sliding piece 8 then, after this similar with unloaded backhaul process.
So, this device namely can be implemented between pipe racking frame and the rig floor 1 and transmit drilling tool and tubing such as drilling rod 4, drill collar back and forth.
The utility model is not limited to above-described embodiment; be not limited to transmit drilling rod; also can be used for transmitting other drilling tools or tubing; be not limited to for oil-well rig; can also make multiple variation according to the purpose that utility model of the present utility model is created; all according to technical solutions of the utility model spiritual essence and principle under make change, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, all belong to protection domain of the present utility model.
