Description

Description of the invention

A useful model applies to the oil and gas industry and is used to eliminate accidents at oil 2 and gas wells.

A known device for guiding anti-spill equipment to the mouth of a gushing well, which contains a drive to move the anti-spill equipment to a vertical position, a mouth grabber, which is made in the form of a plate with fingers and a node for attaching the anti-splash equipment to the mouth grabber, see patent of Ukraine Mo28336 E 21 B 33/00).

This device cannot be used to guide the anti-spill device (gate) at the mouth of the gushing well, which is formed by a flange combined with the body (flangeless base).

The basis of the useful model is the task of improving the device for guiding the gate valve to the mouth of the gushing well, in which, due to the thrust gripper, the screw stop and the system of screw clamps, it is possible to guide the gate valve to the mouth of the gushing well, which is formed by 12 flanges combined with the body (flangeless base). .

The task is solved due to the fact that in the device for guiding the gate valve to the mouth of a gushing well, which contains a drive for moving the gate valve to a vertical position, a mouth grabber, which is made in the form of a plate with fingers and a node for attaching the gate valve to the mouth grabber, the new thing is that the mouth grabber plate is equipped with a bracket, which is made of two plates rigidly connected to each other with the formation of a gap between them, the device is equipped with a stop grabber, which contains a screw stop, the grabbers are equipped with a system of screw clamps connected to them, the mouth grabber bracket is hinged with connected to the drive to move the latch to the vertical position.

The mouth grabber is installed on the emergency spouting flange, which is combined with the body (flangeless base), and is connected to the thrust grabber with the help of screw clamps. At the same time, 22 forms a rigid connection of the type of clamp, which is additionally pressed up with a screw - stop for rigidity.

The device for directing the valve to the mouth of the gushing well (hereinafter referred to as the device) contains a mouth grabber 1, which is made in the form of a plate with fingers 2 (see Fig. 4). Fingers 2 are inserted into the pin holes of the emergency gushing flange From the adapter to the FA pipe head, which is combined with the « body (flangeless base). The plate of the mouth grabber 1 is equipped with a bracket 4, which is made of 40 two rigidly connected plates 5 with the formation of a gap between them (see Fig. 3). The device is equipped with a stop gripper b, which contains a screw stop 7. The stop gripper b is pressed under the upper flange of the pipe head 8. The throat gripper 1 is connected to the stop gripper b by means of screw clamps 9 and 10. At the same time, a rigid c "clamp-type connection, which for rigidity is additionally pressed up by a screw stop 7, which rests on the lower flange of the pipe head body 8 49 FA. The device includes a drive to move the latch 11, which is guided, into a vertical position. The drive includes a bracket 12, which is hingedly connected to the bracket 4 of the mouth grabber 1. The bracket 12 is equipped with a fastening assembly 13 of the latch 11 to the mouth grabber 1. The drive also includes a hydraulic cylinder 14, the body of which is hinged to the bracket 4 of the mouth grabber 1 , and the rod - with the attachment unit 13 using o bracket 15. o 20 The device works as follows.

On the upper part of the emergency gushing flange Z of the adapter to the FA pipe head, which is combined with the "a" body (flangeless base), a mouth gripper 1 is installed, the fingers 2 of which are inserted into the pin holes of the flange 3. A stop gripper 6 is installed under the upper flange of the FA pipe head 8. After that, the mouth and stop grabbers 1 and b are connected with the help of screw clamps 9 and 10, which connect the plates 5 of the bracket 4 of the mouth grabber 1 with the stop grabber 6. At the same time, a rigid clamp-type connection is formed. For additional rigidity attachment of grabbers 1 and b stop grabber 6 are pressed up with the help of a screw stop 7, which rests against the lower flange of the pipe head housing 8

F. After that, on the latch 11, which is planned to be guided, the fastening assembly 13 of the latch 11 is fixed to the muzzle grabber 1. The bracket 12, which is equipped with the fastening assembly 13, together with the latch 11, is connected to the 60 bracket 4 of the muzzle grabber 1 using an axis. Rotate the fastening unit 13 with the latch 11 around the axis of the bracket 4 and bring the latch 11 to the original position. Then, between the plates 5, the bracket 4 is installed and hingedly connected to the last body of the hydraulic cylinder 14 of the drive 10. The rod of the hydraulic cylinder 14 is hingedly connected to the bracket 15 by the fastening unit 13.

Pressure is created in the rodless cavity of the hydraulic cylinder 14. At the same time, the latch 11, which is equipped with a sealing ring, rotates around the rotary joint of the bracket 4 and contacts the corresponding emergency spouting flange 3. The formed flange connection is fixed with pins and nuts.
