DEVICE FOR DISPLACEMENT OF PIPES Russian patent published in 2010 - IPC E21B19/14 

FIELD: oil and gas production.

SUBSTANCE: device for displacement of pipes comprises the main support structure, ramp between the main support structure and floor of drilling rig, pipe holder on the main support structure, lifting lever, guide on the main support structure for provision of axial motion of holder and lifting lever along it, and system of drive for motion of holder from lower position along ramp into lifted position. Pipe holder comprises ramp end, remote end and groove for pipe placement. Lifting lever is hingedly joined to holder at its first end, adjacent to remote end of holder, and is arranged below holder, in order to lift and support remote end of holder in lifted position. Guide on the main support structure comprises support element for limitation of axial motion of the second end of lifting lever along guide towards the frame. System of drive makes it possible to pull the lifting lever along the guide until it stops against support element on guide, and makes it possible to continue pulling, in order to turn lifting lever relative to support element, in order to lift remote end of holder.

EFFECT: reduced danger of pipes falling, equipment damage and personnel injury, installation of pipe in inclined position for easy access to its end for lifts, reduction of manual operations with pipes.
