The specific embodiment

Be further described below in conjunction with the specific embodiment of Figure of description a kind of three-dimensional drilling rod of the utility model automatic discharge device.

Referring to Fig. 1-shown in Figure 9, a kind of three-dimensional drilling rod automatic discharge device, comprise main folder pincers and translation system, auxiliary clamp and translation system, vertical slideway system, control system, wherein: stepper motor drives main move left and right double sided slider bar 3 and the auxiliary move left and right double sided slider bar 7 of stepper motor driving is slidingly arranged between right column slide rail 5 and the left column slide rail 6; Stepper motor drives main move left and right double sided slider bar 3 one ends and is connected with the single slide rail 4 of main folder pincers move left and right, main folder pincers telescopic arm 2 drives main folder pincers telescopic arm slide block 1 by stepper motor and is arranged on the single slide rail 4 of main folder pincers move left and right, and main folder pincers telescopic arm 2 one ends are provided with a hydraulic clamp 11; Stepper motor drives auxiliary move left and right double sided slider bar 7 one ends and is connected with the single slide rail 10 of auxiliary clamp move left and right, auxiliary clamp telescopic arm 9 drives auxiliary clamp telescopic arm slide block 8 by stepper motor and is arranged on the single slide rail 10 of auxiliary clamp move left and right, and auxiliary clamp telescopic arm 9 one ends are provided with a hydraulic clamp 11.

This three-dimensional drilling rod automatic discharge device is arranged between the side and safety platform 13 of derrick 12, be implemented in drilling rod in the work flow such as make a trip and make up a joint lifting, transfer, during operation such as translation, the omnidistance unmanned numeral control automatically of clamp track.

In the course of the work, the clamping of hydraulic clamp 11, unclamp action and provide power to realize by hydraulic motor and hydraulic cylinder, major-minor clamp and translation system are realized by PCL839 motion control card and IPC Industrial Personal Computer (IPC) control step motor along the mobile of X, Y, three directions of Z, adopt NC to embed PC formula structure, transmit signal by PCLD-782/785 signal input-output card, realize the digital control of pipe racking.Be example to make up a joint, to play thribble respectively below, introduce the well pipe handling equipment operating principle:

Job step makes up a joint: the X that 1. controls the auxiliary clamp translation system, Y, three direction stepper motors of Z, translation auxiliary hydraulic pressure clamp 11 is on the well near the kelly bar lower contact, 2. closed hydraulic clamp 11, help the kelly bar lower end, control X, Y, three direction stepper motors of Z, mobile kelly bar lower end and mouse hole drill pipe joint make-up, 3. after cooperating iron driller to link closely, partly unclamp hydraulic clamp 11, kelly bar and drilling rod can be moved up and down in

hydraulic clamp

11,4. leave mouse hole with hoist kelly bar and drilling rod of drilling well hoisting system, 5. closed hydraulic clamp 11, control X, Y, three direction stepper motors of Z, mobile drilling rod lower end and well head drill string make-up, 5. cooperate iron driller to link closely after, unclamp hydraulic clamp 11, control X, Y, three direction stepper motors of Z are got back to home, and the operation that makes up a joint of auxiliary hydraulic pressure clamp 11 and translation system finishes.

Play thribble job step: the X that 1. controls major-minor hydraulic clamp translation system, Y, three direction stepper motors of Z, synchronous translation master hydraulic clamp 11 and auxilliary hydraulic clamp 11 are near the upper and lower side of well head top thribble respectively, 2. after opening major-minor hydraulic clamp 11 synchronously, main hydraulic clamp 11 clamps on the thribbles near the end joint, while auxiliary hydraulic pressure clamp 11 semi-closed doubling-up posture in standing (qigong) root lower ends, 3. control the main hydraulic clamp Z of system and promote thribble to design height to stepper motor, 4. control the translation system X of major-minor hydraulic clamp 11, Y both direction stepper motor, main hydraulic clamp 11 and translation system translation thribble upper end are to the pipe rack assigned address, auxilliary hydraulic clamp 11 and the synchronous translation thribble of translation system lower end are to the pipe setback assigned address, 5. control main hydraulic clamp 11Z to stepper motor, transfer thribble in pipe setback, 3. after fixing thribble on the pipe rack, major-minor hydraulic clamp unclamps simultaneously, turn back to initial position, prepare to carry out next and play the thribble operation.

The effect of main hydraulic clamp and translation structure is: clamp and mention the bigger thribble of weight and move to assigned address.

The translation of auxiliary hydraulic pressure clamp is configured with two effects: one, when main hydraulic clamp 11 picks up thribble, cooperate main hydraulic clamp 11 to set upright the thribble lower end, limit its swing, and move to the well head make-up or move to the pipe setback assigned address with main hydraulic clamp 11, at this moment, the auxiliary hydraulic pressure clamp can not constructed to add and is held and castering action, and only rise and set upright phorogenesis, and the size of its translational movement, direction, time and main hydraulic clamp system synchronization; Two, when making up a joint, set upright kelly bar and mouse hole drilling rod make-up, set upright drilling rod and well head drilling tool make-up, and cooperate iron driller to link closely.

Vertically the slideway system mainly plays guiding main folder pincers and the vertically translational motion of translation system, auxiliary clamp and translation system, works to support whole drilling rod automatic discharge system simultaneously.
