INSTALLATION OF STORAGE, DISPENSING AND RECEPTION OF PIPES DURING LOWERING AND RAISING OPERATIONS Russian patent published in 2020 - IPC E21B19/14 

FIELD: mining.

SUBSTANCE: invention relates to drilling of oil, gas and other wells. Installation of storage, delivery and reception of pipes during tripping operations comprises base with central vertical post, racks made with possibility of rotation along vertical axis, drive for rack rotation arranged inside base, pipe gripping device, which is fixed, for example, on its vertical post and arranged on pipe supply line. According to the invention racks are made in the form of a single rigid cassette and are equipped with replaceable support grates located in upper and lower parts, replaceable support grids are formed by rod elements forming cells of different size and equipped with interconnection nodes and with racks, as well as the plant is equipped with a second gripping device, placed on a telescopically telescoping post, comprising a pivoted in vertical plane console with a working member serving to hold pipes.

EFFECT: as a result, the plant operation reliability is increased due to the racks in the form of a single rigid structure, the elements of which are fixed relative to each other, reducing the manufacturing and operation costs, wider range of pipe diameters due to formation of cells of required size in form of replaceable support grids for storage of required pipes from replaceable rod elements, having connection nodes for connection between each other and with shelves.
