Description

The invention relates to devices for assembling threaded connections and can be used for tightening large-sized threaded connections in hard-to-reach places.

A device for assembling threaded connections is known, comprising a pushing element in the form of a sleeve, placed in the transverse groove of a threaded connection element, a wedge-shaped force mechanism with a shank in which a screw is interconnected with the threaded connection element I.

The disadvantage of this device is the impossibility of dismantling it after the assembly of the threaded connection.

Closest to the invention is a device for assembling threaded connections, comprising a pushing element in the form of a sleeve, an insert mounted on it with a transversely bevelled slot, a wedge body with a perpendicularly transversely slotted slotted slotted therein, a power mechanism made in the form of a driving screw flange and interacting with the screw wedge nut installed with the possibility of axial movement in the slot wedge body, and placed on the liner nut 2.

A disadvantage of the known device is the inconvenience of working in hard-to-reach places.

The aim of the invention is the convenience of working in hard to reach places.

The goal is achieved by the fact that a device for assembling threaded joints, comprising a pushing element in the form of a sleeve, an insert mounted on it with a cross-sectioned slot, a wedge body arranged therein with a perpendicularly transversely slotted slotted slot, a force mechanism made in the form of a driving screw a flange and a wedge nut interacting with a screw, mounted with the possibility of axial displacement in the slot of the wedge body, and a nut placed on the liner, equipped with a thrust placed in the sleeve, and eyuschey grip element for a threaded connection at one end to the other - for threaded engagement with a nut and a jack screw drive flange, and in the middle part - a transverse slot for receiving the lift mechanism and the wedge body.

The drawing shows the device, a longitudinal section.

A device for assembling threaded connections comprises a pushing element in the form of a sleeve 1, an insert 2 mounted on it with a transversely beveled slot 3, a wedge body 4 accommodated therein with a transverse slot 5 perpendicular to the transverse slot 3, a force mechanism, made in the form of a driving screw 6 with a flange 7 and a wedge nut 8, which interacts with a screw 6, mounted for axial movement in the slot 3 of the wedge member 4. The device is equipped with

 placed in a sleeve 1 of a thrust 9, having a grip 10 for a threaded joint element 11 at one end, at the other a thread for engagement with a 2 nut 12 placed on a liner and a nest 13 under the tongs 14, on which the flange 7 of the driving screw 6 is mounted, and in the middle part there is a transverse slit 15 for accommodating the force mechanism and the wedge member 4. The sleeve 1 has radial holes 16 for screwing the nut 17 of the threaded connection.

The device works as follows.

To assemble the threaded connection after pre-tightening the nut 17

0, the device is put on a threaded connection and screwed on the grip 10 tons of gi 9 into the threaded hole of the stud 11. For this, the upper end of grip 9 is made in the form of a hexagon. Then with the help of a nut 12, turned onto the threaded end of the string 9, they make

5 pre-tightening of the threaded joint. For the final tightening of the threaded joint, the driving screw 6 is rotated, as a result of which the wedge body 4 is moved along the bevelled

- Slot 3 of the liner 2 and creates a tightening force. After that, the nut 17 of the threaded connection through the hole 16 in the sleeve 1 turns up to the stop against the end of the assembled product.

The present invention improves

5, it is convenient to work when tightening threaded connections in hard-to-reach places, which has the effect of reducing the labor intensity during assembly of threaded connections.
