SU1033697A1 - Elevator for running pipes into well - Google Patents

Description

The invention relates to the drilling of wells, and in particular to devices for lowering pipes into a well.

A known epevator of central pipe descent into a well, which includes a housing with a lock and a sash Cl 3.

The disadvantage of it is the impossibility of emergency pipe throwing into the well.

The closest technical solution to the invention is an elevator dp of pipe descent into the well, including a case with a lock and a flap f 2}.

The disadvantage of this device is that it does not allow emergency discharge of pipes into the well.

The acquisition chain is to ensure the emergency discharge of pipes into the well.

This goal is achieved by the fact that the epevator .dp pipe descent into the well,

; Composites of the case with a lock and casement are supplied; with a drive of the emergency disconnection of the elevator from the pipes installed in the vice cylinder and a lever hinged on the case, the lever has the ability to interact with the case lock and the hydraulic cylinder rod with the pipe.

FIG. 1 image & ken epevator, oyaya view; in fig. 2 - the same, in the working wise; in fig. 3 - the same, top view.

The device consists of Kopnjtcju.i Hydro-rotsishshdra with nozzle 2 and rod 3. On the housing 1, the hydraulic cylinder is rigidly fixed in the form of a plug 4 and paped S, which are pivotally connected to the frames 6. On one of the four pap 4 para-axis of the housing 1 hyarocylinder fixed hook 7. The latter may be attached to the paw as hard as such a sliding in the sleeves 8 with the reversing bolt 9.

The device is installed on the elevator 10 by putting on the frame 6 on its diametrical trunnions AND, - thus

 that hook 7 is engaged with the lock 12 of the flap 13 of the elevator 1O. Moreover, since the lock 12 is below the device fingers 5, the entire device becomes under: an angle to the axis of the elevator 10. The latter rests on the column flange 14 of the well, and the coupling 15 of the pipe string 16 rests on it. The hook hook 7 can lock adjusted by moving the hook 7 with the adjusting screw 9.

The device works in a dim way.

Through fitting 2 into the housing 1

| lindra serves hydraulic pressure. 3 extends from housing 1 and rests on sleeve 15; the Voskakvda force on the rod 3 turns the device on

 fingers 5 in a perpendicular position to the axis of the pipe string 1b, coupling 15, elevator 10 and column flange 14. Turning, the device lifts lock 12 with its hook 7, holding it further and releases the gate 13 of the elevator. 10. In this position, the column of pipes 16, with its coupling 15, rests on the elevator 1O and its gate 13 and is

Hanging condition in the well 14i. A further sipa has been displaced by a rod 3

 Generally, it presses on the sleeve 15 and partly shifts it together with the column pipe 16 relative to the elevator 10 toward its gate 13, Fully rotated at its hinge and the output of the support of the sleeve 16 begins to open. on the side of the rod 3, it comes off the stop of the edges of the eupatator 10 and under the action of the weight of the copon tubes 16 is felled and carried along by the opened elevator 10 into the well column 14,

By ensuring that the epevator has a disconnect drive, an emergency discharge of pipes into the well is provided.
