Description of drawings: Fig. 1 is a sectional side elevation of the present utility model;

Fig. 2 is a vertical view of the present utility model.

The specific embodiment: referring to Fig. 1, Fig. 2; A kind of underground work oil pipe erection device is by turning arm 1, spiral arm support 2, telescopic arm 3, connecting axle 4, worm gear 5, worm screw 6, support 7, slide rail 23, leading screw 8, motor 9, fixed armrest 22, movable hand rail 19, rotating shaft 10, motor 11, axle sleeve 21, form near switch 12, switch 14, switch 15, switch 16, switch 27, control panel 17, infrared light emission source 18, motor 20; Telescopic arm 3 front ends have axis hole, and connecting axle 4 is housed in the axis hole, fix with axle sleeve and shelves platform; Worm gear 5 is sleeved on the middle part of connecting axle 4, with key connecting; Motor 20 is installed on the telescopic arm 3, and the axle and the worm screw 6 of motor 20 are used key connecting, is equipped with big nut; Worm gear 5 and worm screw 6 interlocks; The axle sleeve 21 that is welded with spiral arm support 2 is sleeved on the lower end of connecting axle 4, with key connecting; The turning arm 1 that has fixed armrest 22 embeds in the spiral arm support 2 interference fit; Turning arm 1 side is equipped with near switch 12; Infrared light emission source 18 is installed in the button oil pipe place of fixed armrest 22; Fixed armrest 22 and movable hand rail 19 correspondence respectively have axis hole, and rotating shaft 10 1 ends place the interior key connecting of also using of the axis hole of movable hand rail 19; Rotating shaft 10 other ends are inserted in the axis hole of fixed armrest 22; Motor 11 is installed in turning arm 1 below, and key connecting is used in the axle and the rotating shaft 10 of motor 11; Slide rail 23 is installed on the two stands 7; Motor 9 is fixed on the support 7; The axle and the leading screw 8 of motor 9 are used key connecting; Leading screw 8 inserts in the axle sleeve of telescopic arm 3 bottoms, is threaded; Be connected with switch 15 by lead 13 near switch 12, motor 11 is connected with switch 15 by lead 24; Motor 20 is connected with switch 27 by lead 25; Motor 9 is connected with switch 14 by lead 26; Infrared light emission source 18 is connected with switch 16 by lead 28; Switch 14, switch 15, switch 16, switch 27 are installed on the control panel 17.

Carry out before oil pipe sets upright, a kind of underground work is connected fastening with the support 7 on the oil pipe erection device with workover derrick, and the preceding movable hand rail 19 of assurance work is an open configuration; Open switch 16 and make infrared light emission source 18 emission infrared light beams; Open switch 14 starter motors 9 and drive leading screw 8 rotations, leading screw 8 forward or reverse driven rotary arms 1 shrink or protract to pithead position; Opening switch 27 starter motors, 20 drive worm screws 6 and turbine 5 is more just changeing, and makes connecting axle 4 driven rotary arm supports 2 and turning arm 1 rotate to the appropriate location; By opening and closing switch 14 and switch 27 repeatedly, adjust the position of fixed armrest 22, aim at the well head center until the infrared light emission bundle, close infrared light emission source 18 then; Open switch 15 and make motor 11 drives revolve axle 10 counter-rotatings, movable hand rail 19 inside closures are held together oil pipe, and oil pipe is set upright; After setting upright oil pipe or oil discharge pipe, open switch 15 motor 11 drive rotating shafts 10 are just being changeed, make movable hand rail 19 be flared to shake-up, close switch 15, motor 11 is stopped operating near switch 12 near switch 12; Open switch 27 and make motor 20 drive connecting axle 4 counter-rotatings, make 2 counter-rotatings of spiral arm support, the work of once setting upright is finished in turning arm 1 counter-rotating playback.

So repeatable operation is finished the oil pipe of whole mouthful of well and is set upright work.

Connecting axle 4 can directly drive with motor shaft in theory, and needn't adopt turbo-dynamo.But in real work,, when 19 pairs of oil pipes of movable hand rail are set upright motor shaft is produced reaction force, the axis phenomenon takes place because oil pipe tilts.And the self-locking structure of turbo-dynamo just can head it off.
