Fig. 2 is Elevator structure schematic diagram of the present utility model；
Fig. 3 is centralising manipulator structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described:
As shown in Figure 1, a kind of workover treatment removes tubular column unit, including hook 1, suspension ring 2, elevator 3, centralising manipulator 4, hydraulic tongs 5, jigger 6, oil pipe slideway 7, slideway lifting machine 8, well head 9, preventer 10, air spider 11 and operation dish 12, hook 1 connects suspension ring 2, suspension ring 2 connect elevator 3, centralising manipulator 4 is arranged between elevator 3 and hydraulic tongs 5, jigger 6 is arranged on oil pipe slideway 7, oil pipe slideway 7 is arranged on slideway lifting machine 8, air spider 11 connects preventer 10, preventer 10 is arranged on well head 9, operation dish 12 connects hook 1 by messenger wire.
Elevator includes elevator body 13, block ring 14, sector gear 15, protective cover 16, fixing bolt 17, fixing lacing wire 18 and gerotor motor 18, sector gear 15 is arranged on the centre of elevator body 13, block ring 14 is arranged on the both sides of sector gear 15, it is outside that protective cover 16 is arranged on sector gear 15, fixing lacing wire 18 is arranged on the both sides up and down that cycloid horse 18 reaches, and fixing bolt 17 makes fixing lacing wire 18 be fixed on elevator body 13.
Centralising manipulator includes mechanical hand 20, mechanical arm 21, support 22 and pedestal 23, and the fixing pedestal 23 that connects of support 22, mechanical arm 21 is fixing connects support 22, and mechanical hand 20 is connected to the right-hand member of mechanical arm 21.
Work process: play oil pipe: workover rig driver control overhead traveling crane hook drives suspension ring elevator descending, when elevator arrives in the crescent moon of well head suspension the 1st oil pipe top following body position of box cupling of tubing string and oil pipe entrance elevator, handle elevator hydraulic motor to rotate, close block ring and pin oil pipe.Lift up tubing string immediately, open tubing spider.When next the root tubing coupling mentioning tubing string is concordant with hydraulic tongs back-up tong head, stop pipe, close tubing spider locking tubing string.At this moment driver pulls hydraulic tongs forward gear handle, and hydraulic tongs shifts to oil pipe, until oil pipe enters in the jaw of hydraulic tongs, then pulls hydraulic tongs motor reversion block handle, and the clamping tubing coupling of hydraulic back-up tongs binding clip, the main pincers of hydraulic tongs start shackle.If high speed break-out torque is inadequate, is then changed hydraulic tongs into bottom gear by top gear by Pneumatic shift handle, dismantle tubing thread.Automatic notch alignment device can ensure that hydraulic tongs jaw is in maximum open state, makes hydraulic tongs recess oil pipe smoothly and return to original position, waits that shackle next time operates.It follows that mechanical arm promotion robot is automatically stopped when encountering the oil pipe of firm shackle, lifts up oil pipe and leave box cupling 5～15cm, drain line under while mechanical hand continuation outwards propelling movement oil pipe, make oil tube external thread sit up straight in the jigger on oil pipe slideway.Oil pipe relies on deadweight outwards to slide along slideway, until tubing coupling terminates after contacting oil pipe slideway, driver manipulates the reversion of elevator motor, opens block ring release oil pipe.The mechanical hand retraction stretched out, when next root tubing coupling lower pipe body enters in the crescent moon of elevator, shuts rapidly elevator block ring.Meanwhile, yardman presses remote controller, sets level slideway, pulls out oil pipe, and oil pipe rolls on oil pipe crane span structure, then rises slideway front end.Repeat above-mentioned pipe operation, whole oil pipes in well can be tripped out.
Lower oil pipe: yardman presses remote controller and translates in slideway by oil pipe from pipe bridge, hydraulic cylinder pushes tubing coupling end and arrives well head correct position, rises slideway front end.Mechanical hand promotes suspension ring to drive elevator descending, and when arriving the following body position of the tubing coupling on slideway, manipulation elevator closes block ring, catches oil pipe.While sling, mechanical hand is regained on oil pipe limit, and oil pipe moves to well head gradually, and when hanging tubing string female end center alignment in the oil tube external thread end sling with well head, mechanical hand is automatically stopped movement.Driver transfers oil tube external thread end and enters the coupling inner thread of well head suspension tubing string, and mechanical hand returns to original position, concedes space, and it is in place that manipulation hydraulic tongs shifts to oil pipe, and the clamping tubing coupling of back-up tong binding clip, main pincers complete button.Then hydraulic tongs automatic notch alignment recess oil pipe and return to original position, waits and detains operation on next time.Mention tubing string, open tubing spider and unclamp tubing string and transfer, when tubing string top box cupling arrives hydraulic tongs back-up tong binding clip flush position, stop transferring, close tubing spider and pin tubing string.Then, mechanical hand promotes suspension ring to drive elevator to capture next root oil pipe.Repeat above-mentioned lower tubing manipulation, under enter whole oil pipe.
