Description

one

The invention relates to the mining industry, in particular to devices for the mechanization of launching operations when drilling a well, and can be used to move pipes between the mouth of a well and racks.

The aim of the invention is to increase the reliability of the device operation by ensuring that pipes of various lengths are fixed in the channel. {FIG. shows the proposed device, a general view; figure 2 - node I in figure 1; FIG. 3 is a section A-A in FIG. 2; in Fig.4 section bB in Fig.2; in Fig „5 - section В-В on () ig.2; Fig.6 section GG on () ig.2.

The device contains a tet, a hedgehog 1 with | 1 front 2 and rear 3 wheels, on which is mounted a chute A,

The wheels of the trolley 1 are placed in the front 5 ramps. Along the walkways of the Yizhe zhepo ba 4, a profile roll 6 with shelves, for example an I-beam, is installed. A profile carriage 7 is placed on the profile beam 6 with an emphasis for a movable pipe. The movable carriage 7 is installed with the coverage of the chute 4 and is connected with the drive 8 of the movement of the trolley 1.

The limiter of the lower position of the trolley 1 is implemented in the form of the upwardly bent ends of the 9 guides 5,

At the lower end of the chute 4 is installed the gripping unit of the movable carriage J7, made in the form of a dog. 10, spring-loaded with respect to groove 4 by a spring 11, the dog is mounted on an axis 12 fixed to the cheeks 13, and

has a rack 14, as well as a pusher 15, equipped with a roller 16, which interacts with a movable protrusion 17 of the walkways.

On the movable carriage 7, a wedge-type stop assembly is provided, represented by wedges 18 placed in guides 19, which are rigidly connected to the limited-movable linings 20. The limited-movable motion of the linings 20 is provided by means of fingers 21 connected to the guides I9 in the longitudinal grooves made in the housing of the movable carriage 7. To ensure the return of the guides 19 to the initial position and, therefore, to relieve the forces from the profile beam 6 wedges 18 gangs 22 mounted on rods 23; To eliminate longitudinal movements of wedges 18, stops 24 and 25, mounted in the housing of the movable carriage 7, serve;

The movable carriage 7 is in contact with the chute 4 by means of rollers 26, and with the profile beam (its shelves) 6 by means of rollers 27, the connection of the movable carriage 7 with the drive 8 of movement of the trolley 1 is through a link 28 connected to the pads 20 at the end of the flexible rod (cable) 29. Interacting with the pawl 10 on the movable carriage 7 is set to the bracket 30. The trolley 1 is held in its upper position by the locking of the upper position of the trolley (not shown).

The device works as follows.

The pipe to be transported to the wellhead is laid in the chute 4, and the coupling end extends beyond the chute by a value convenient for gripping by the elevator. The actuator 8 is turned on. Moving the carriage 7 under the tension of a flexible cable (cable) 29 moves along the chute 4 until it stops against the pipe. The carriage body 7, together with the wedges 18, stops the pads 20 by means of the fingers 21 pushing the guides 19 in the direction of travel. In this case, the wedge 18 is pressed against the shelves of the profile beam 6. The pipe is fixed in a certain position along the length in the groove 4. With the help of the drive 8, the carriage 7 with the gripped groove 4 and the pipe is connected

By the drive 8, the trolley 1 rises to the end towards cix 5 and is fixed in the upper position. Drive 8 is disabled. The pipe is lowered into the chute 4 to the required level so that the elevator can be opened. By raising the movable extrusion on the inclined section on the cich (not shown), the movable carriage 7 disengages from the pawl 10, the actuator 8 is turned on, and the movable carriage 7 rises up to the stop against the lower end of the pipe and seizes the chute 4. Releasing from the fixer the upper position of the carriage and the braking drive 8, the chute 4 with the pipe is lowered to the lower position. At the end of the chute stroke, the actuator 8 is disinhibited. Since the horizontal section has

well axis. The pipe is grabbed by the elevator and then lifted. In this case, the lower end of the pipe is guided along the chute to the rotor.

To move the next pipe, the chute 4 is lowered to a horizontal position. For this, the actuator 8 is disengaged, under the influence of the spring 22, the guides 19 are pressed, the wedge 18 moves away from the shelves of the profile beam 6, under its own weight the movable carriage 7 descends to the lower end of the chute 4. Bracket 30 pushes the dog 10, and the movable engagement occurs the carriage 7 with the chute 4 by means of the dog 10.

The cart 1 is released from the latch of the upper position (not shown) and with the drive braking 8 opus

16, the pusher 15, the raid on the movable protrusion 17, lifts the pawl 10, and the movable carriage 7 is released from the engagement. Chute 4 is ready to receive the next pipe.

To lower the pipe and move it to the gangways, the chute 4 is raised along the guides 5 to the upper position and fixed. For this purpose, in the horizontal position of the chute 4, the protrusion 17 is sunk by a pneumatic cylinder (not shown) by an amount of lifting of the dog 10. When the spring 11 is gripped by the force of the spring 11, the dog 10 is lowered to the bracket 30 and engages the movable carriage 7.

By the drive 8, the trolley 1 rises to the end towards cix 5 and is fixed in the upper position. Drive 8 is disabled. The pipe is lowered into the chute 4 to the required level so that the elevator can be opened. By raising the movable extrusion on an inclined section of the guide (not shown), the movable carriage 7 is uncoupled from the pawl 10, the actuator 8 is activated, and the movable carriage 7 rises up to the stop against the lower end of the pipe and seizes the chute 4. Release from the fixer the upper position of the carriage and the braking drive 8, the chute 4 with the pipe is lowered to the lower position. At the end of the run of the chute, the actuator 8 is disinhibited. Since the horizontal section has

At the lower left end of the horizontal section of the guides, 5 there is a sharp rise — the ends of the guides 9 that are bent upward, 5, i.e. the lower position of the cart 1. The cart 1 in this area is braked due to lifting, the pipe located on the chute, overcoming the force of friction, moves further to the left by inertia and moves the movable carriage 7, which moves on the rollers 26 and 27, fingers 21 driven by the body of the movable carriage 7, move the guides 19 to the left relative to the wedges 18. Since the wedge 18 and the guides 19 are connected by l-shaped grooves, and the limiting movement of the wedges is limited by the stops 24 and 25, the wedge 18 moves away from the main shelves (I-beam After the second beam 6, the movable carriage 7 is disconnected from: - the forehead 4, reaches the pawl 10 and engages with the clevis 30. After extinguishing the kinetic energy of the movement of the tube with the movable carriage 7, the cart is lowered from the upwardly bent ends of the 9 guides 5 (left inclined plot) on their horizontal plot. The pipe from the chute 4 of the trolley 1 is taken out and the latter is again ready for the next cycle, for which the actuator 8 is again turned on for raising the bed 1, the cycle is repeated.
