FRAME SYSTEM AND METHOD OF ITS OPERATION Russian patent published in 2019 - IPC E21B41/00 F16M13/00 

FIELD: building structures.

SUBSTANCE: group of inventions relates to the field of space frame structures for surface Christmas tree, in particular to the frame system and method of its operation. System of frames for surface-mounted Christmas tree includes protective frame and transportation frame. Protective frame is a spatial structure comprising a first frame module and a second frame module, each of which comprises rectangular cross-section beams interconnected by a welded joint to form a parallelepiped-shaped structure, at least two sides of which are formed by a grid connected to the beams by a bolt joint, in two extreme vertices of each frame module on beams first conveying lugs with one hole are located, between which there are multi-eye lugs with multiple holes on beams. Protective frame is made with possibility of installation of surface-mounted Christmas tree in it by attachment of surface-mounted Christmas tree in at least two attachment points. At least one first attachment point is located on beam of first frame module. At least one second attachment point is located on beam of second frame module. Protective frame with surface-mounted Christmas tree is mounted on transportation frame by means of fixation. Transporting frame is a spatial structure including a working part and a transportation part arranged mutually perpendicular. Working and transportation parts comprise beams of double-tee section, interconnected by welded joint. Working part includes at least two hollow beams for fork lifts. Working part comprises second conveying lugs arranged at ends of beams of working part, and transportation part comprises third conveying lugs located at ends of beams of transportation part. Transporting frame is in working horizontal position when its working part is located in horizontal position, and its transportation part is located in vertical position. Transporting frame is in transport vertical position when its working part is located in vertical position, and its transportation part is located in horizontal position. Transporting frame is made with possibility of its transfer from working horizontal position to transportation vertical position and vice versa using at least first lugs.

EFFECT: technical result consists in providing the proposed system frame transfer from the horizontal position into the vertical frame with installed in the protective frame Christmas tree, having a shifted center of gravity.
