MULTIFUNCTIONAL MODULAR FRAME FOR EQUIPMENT MAINTENANCE Russian patent published in 2021 - IPC E21B41/10 E21B19/00 F16M13/00 

FIELD: mining industry.

SUBSTANCE: invention relates to the field of spatial frame structures and can be used in well access systems and for other equipment of the underwater hydrocarbon production system, in particular for underwater wellhead equipment. The multifunctional modular frame for servicing the equipment of the underwater mining system contains: a base made with the possibility of installing horizontal guides on it for moving the plate with a test sleeve mounted on it, made with the possibility of connecting to the equipment of the underwater mining system; vertical guides, made with the possibility of installation in each corner of the base, for directing the equipment of the underwater mining system when it is connected to the bushing. Each vertical guide corresponds to a plate with clamps for fixing the equipment of the underwater mining system and a central hole, made with the possibility of placing it on a vertical guide, ensuring free movement of the plate along the vertical guide and fixing the plate relative to the vertical guide by means of crossbars made with the possibility of installation in pockets made in the form of through holes in the vertical guides and located along their longitudinal axis. The vertical guides are equipped with eyelets in their lower part. The multifunctional modular frame also contains at least one hydraulic cylinder installed in the lower part of the base below the level of the upper surface of the base and made with the possibility of moving the plate.

EFFECT: increase in the reliability of operation of the multifunctional modular frame and expansion of its functionality, including the possibility of transporting the proposed frame with the equipment of the underwater mining system installed on it.
