SU1620162A1 - Carriage for movable rotator - Google Patents

Abstract

The invention devotes itself to the mining industry, namely to devices for tripping operations with drill pipes. The purpose of the invention is to provide enhanced functionality by laying drill pipes on a horizontal rack and securely fixing the rotator in the working position. The carriage includes a housing 1 mounted on the base, probably on the guide masts 2, a rotator 4 hinged to the housing 1 by means of levers 5 and pillars 6, a rotational displacement drive in the form of hydraulic cylinders and 1 h whose hinges are fixed to the housing 1, and the rods 13 with pins 14 are in the grooves 16 of the uprights 5; the fixing unit of the rotator 4 is made in the form of spring-loaded cheeks mounted on the axes 15 of the pins 14 and having the rotator A located in its grooves at the working position. The grooves 16 of the uprights 6 and the grooves of the rotator 4 are made along the axes of the hydraulic cylinders 11 when the rotator is in the working position, and the spring-loaded cheeks fix it in slots. To retract the rotator 4 from the axis of the well and horizontal pipe laying, the rods 13 retract, remove the spring-loaded cheekbones from the grooves and turn it. In order to return the rotator 4 to the working position, the rods 13 move out, moving along the grooves 16 of the arms 6 and rotate it to the working position. At the same time, spring-loaded jowls, compressing the springs, pass through the conical surfaces and move and the grooves firmly fix the rotator 4 in the working position. 3 il. (L

Description

U

The invention relates to the mining industry, in particular to devices for tripping operations with drill pipes.

The purpose of the invention is to expand the functionality by ensuring that the rotator puts the drill pipe on a horizontal rack and reliably holds the rotator in the working position.

Figure 1 shows the carriage, a general view; on fix2 - the same, the rotator in a horizontal position; on fig.Z - section aa on

fyG.1.

The carriage encloses the housing 1, mounted on the guide masts 2 with the ability to move along them and connected by flexible links 3 to the feed mechanism. The rotator 4 is hinged on housing I by means of levers 5 and pillars 6, which at one end are movably fixed on housing 1 by axles 7 and 8 and rotated on axes A by means of axes 9 and 10. hydraulic cylinders 11, the housings of which with the help of the axles 12 are movably fixed on the housing 1, and the rods

13 are made with trunnions 14, which by means of axles 15 are movably secured in grooves 16 of posts b, ha x x 15 between pins

14 and the rotator 4 is placed spring-loaded cheek 17, and the spring 18 is located between the cheek cheeks 17 and the trunnions 14. The protrusions 19 are made on the overgrown heel having conical surfaces 20 and grooves 21. The grooves 16 of the uprights 6 and the grooves 21 of the rotator 4 are made along the axes of the hydraulic cylinders 11 in the working position rotator 4. Spring-loaded jowls 17 have the opportunity, when the rotator 4 is in the working position, to be placed in the slots 21.

Scrut-j works as follows.

8, the drilling process of the shtoml 13 hydraulic cylinders 11 is in the extended position, the rotator 4 is fixed against rotation by the cheek pins 17 placed in the slots 21.

To retract the rotator 4 from the axis 22 of the well, to lay the drill pipe 23 on the rack, the hydraulic cylinders 11 retract the rods 13, move the axes 15 with the cheeks 17 along the grooves 16, while removing it from the grooves 21. By the time the axes 15 are placed

the lowest position in the grooves 16 of the cheek 17 is completely out of the grooves 21.. With further movement, the rods 13 rotate the rotator 4 to a horizontal

the position of the drill pipe 23. In this position, the drill pipe 23 is released (or secured).

To move the rotator to the working position, the hydraulic cylinders 11 extend the rods 13. The axes 15 move to the upper position in the puzzles 16. With the further extension of the rods 13, the rotator 4 rotates to the working position. In this case, the spring-loaded jaws 17 are rotated onto the tapered surfaces 20, they compress the spring 18. In the working position of the rotator 4, the spring-loaded cheeks 17 under the action of the spring 18 move into the grooves 21, rigidly fix

rotator.
