One, complete the course of work of upper lifting pipe post:
Slips chucking tubing string, and guarantee that tubing string stretches out the length of enough elevator clampings, the mobile operating work moves rearwards to certain position, gets out of the way well head, reserves enough spaces to elevator, guarantees that elevator is to the smooth clamping of tubing string.
It is descending that tourist bus drives elevator, prepare to grasp, and during near string collar, the tourist bus stop motion, elevator tightens hydraulic cylinder piston and stretches out, and the promotion linkage drives elevator door and opens fully, and it is descending that overhead traveling crane drives the elevator continuation, after elevator process box cupling, the tourist bus stop motion.Elevator chucking hydraulic cylinder piston is regained, and drivening rod mechanism also promotes elevator door, and elevator door is closed, and blocks box cupling lower end tubing string, and the retaining mechanism hydraulic cylinder piston stretches out, the drivening rod mechanism kinematic, and promote door and insert and close, clamping body is locked.Afterwards, slip hydraulic cylinder piston stretches out, and drivening rod mechanism moves upward, and promotes the slips body and moves upward, and slips is opened, and tourist bus is up, drives elevator chucking tubing string.When next tubing coupling reached assigned address, tourist bus stopped, and slip hydraulic cylinder piston is regained, and the drivening rod mechanism kinematic is regained the slips body, and slips is closed, and the clamping tubing string makes the outstanding well head that is held in of tubing string.
On the operation work, main pincers breach is in aligned condition, gap means is moved block be in retracted state.Mobile operating work track hydraulic cylinder piston stretches out, and promotes the mobile operating work and travels forward, and the operation work contact with the location buffering block of operation work base front end, and compresses buffer spring, makes power back-up tong arrival tubing coupling position.Back-up tong chucking tubing string, the Long-distance Control master clamps and drives loop and main pincers gearshift loop simultaneously, and it is transferred to low or first gear, is rotated counterclockwise main pincers hydraulic motor, and main pincers chucking tubing string and the button operation of stretching tight are transferred to top gear with main pincers, fast shackle after unclamping screw buckle.
Shackle is complete, the gap means Driven by Hydraulic Cylinder is moved block to gap means, make it to travel forward, withstand opening gear wheel junction plate, the counter-rotating hydraulic motor, when gap means is moved two straight pins in block and the breach in the gear wheel junction plate over against the time, two straight pins are inserted in opening gear wheel junction plate, close the fluid motor-driven loop, this moment, the breach of clamp mechanism alignd with the breach of main pincers housing, and realization operates breach.
Back-up tong unclamps tubing string, and centralising mechanical paw hydraulic cylinder piston is regained, and promotes the centralising mechanical paw and opens, and on derrick, large centralising manipulator pushes away well head with tubing string.It is descending that tourist bus drives elevator, and the oil pipe bottom contacts with slideway, and the comb workman pulls tubing string and slides along slideway.
The gap means hydraulic cylinder piston is regained, and drive is moved block to gap means and is moved backward, arrives predetermined rest position.Mobile operating work track hydraulic cylinder piston is regained, and drives the mobile operating work and moves backward, gets out of the way pithead position.Tourist bus drive elevator continues descending, and elevator overturns along with the descending of tubing string, until near well head, tubing string drops on slideway fully, this moment, elevator was to turn near horizontal level.
The comb workman hauls out pithead position with tubing string, and tourist bus drives the elevator segment distance that moves upward, and under action of gravitation, elevator has horizontal level to turn to vertical position.It is descending that tourist bus drives elevator, and the crawl tubing string repeats the shackle operation.
Two, complete the course of work of transferring tubing string:
Slips chucking tubing string, and guarantee that the length that tubing string stretches out can make hydraulic back-up tongs block the box cupling of tubing string, the mobile operating work moves rearwards to certain position, gets out of the way well head, reserves enough spaces to elevator, guarantees that elevator is to the smooth clamping of the tubing string of beating waiting.
The comb workman is pushed into well head with tubing string along slideway.Tourist bus drives elevator and comes downwards to tubing string top, tourist bus stop motion.Elevator upset makes it near horizontal level, blocks the string collar lower end.Tourist bus is up, drives elevator and promotes tubing string.
On the operation work, main pincers breach is in aligned condition, gap means is moved block be in retracted state.Mobile operating work track hydraulic cylinder piston stretches out, and promotes the mobile operating work and travels forward, and the operation work contact with the location buffering block of operation work base front end, and compresses buffer spring until back-up tong arrival tubing coupling position.
It is up that tourist bus drives the elevator continuation, until tubing string leaves slideway, tubing string contacts the tourist bus stop motion after swinging certain angle with centralising manipulator.Control the centralising mechanical hydraulic circuit, make centralising manipulator crawl and clamping tubing string, make the tubing string center of tubing string center and slips clamping, realize the righting operation of tubing string.
It is descending that tourist bus drives elevator, makes the tubing string lower end enter into box cupling.Control the back-up tong hydraulic circuit, make back-up tong clamp the string collar of slips clamping.
The main pincers hydraulic motor that turns clockwise is adjusted the gearshift hydraulic circuit, makes it to be in low or first gear, makes the tight tubing string of main clamp and carries out the upper operation of buckleing, and be transferred to top gear with main pincers this moment, and upper the button, be transferred to low or first gear with main pincers when upper button closes to an end, the operation of linking closely fast.
Upper button is complete, the gap means Driven by Hydraulic Cylinder is moved block to gap means, make it to travel forward, withstand opening gear wheel junction plate, the counter-rotating hydraulic motor, when gap means is moved two straight pins in block and the breach in the gear wheel junction plate over against the time, two straight pins are inserted in opening gear wheel junction plate, close the fluid motor-driven loop, this moment, the breach of clamp mechanism alignd with the breach of main pincers housing, and realization operates breach.
The gap means hydraulic cylinder piston is regained, and drive is moved block to gap means and is moved backward, arrives predetermined rest position.Mobile operating work track hydraulic cylinder piston is regained, and drives the mobile operating work and moves backward, gets out of the way pithead position.
The slip hydraulic cylinder piston rod stretches out, and drivening rod mechanism moves upward, and promotes the slips body and moves upward, and slips is opened.Tourist bus drives elevator and moves downward, and puts into well with under tubing string.After tubing coupling arrived assigned address, tourist bus stopped.Slip hydraulic cylinder piston is regained, and the slips body is regained in the motion of drivening rod machine, and slips is closed, clamps tubing string, makes the outstanding well head that is held in of tubing string.
