PLATFORM FOR ACCESS TO HYDRAULIC MACHINE AND METHODS OF INSTALLATION AND DISMANTLING OF SUCH PLATFORM IN SUCTION PIPE Russian patent published in 2019 - IPC F03B11/00 E02B9/06 E04G5/08 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a platform for access to a hydraulic machine through a suction pipe. Platform comprises a bearing member configured to slide along longitudinal axis (X1) to enter a pipe opening and having an end portion configured to be fixed therein, flooring elements (270, 272, 274, 276) located on the bearing element. At least some of elements (272, 274) are hingedly connected to bearing element about axes parallel to axis (X1), and are made with possibility of rotation around axes between folded and unfolded configuration, in which they form at least section (27A) of flooring. On lower surfaces of elements (272, 274) there are longitudinal beams made with possibility of fitting into pipe mounting elements. Beams comprise an automatic engagement mechanism comprising a rod and an elastic loading means in the form of a spring pushing the rod towards the seating element. Spring is configured to move the rod in a direction parallel to the length of the beam and oriented towards the wall of the pipe.

EFFECT: group of inventions provides simple and fast installation of platform with reliable fastening, simple and fast dismantling.
