DEVICE FOR RETENTION OF PIN OF HYDRAULIC JACK FOR MOVEMENT OF SUPPORT Russian patent published in 2020 - IPC E21D11/00 

FIELD: construction.

SUBSTANCE: group of inventions relates to a mechanism and a method used for securing a hydraulic jack for moving a support on the basis of a powered support of a system of excavation by lavas, more specifically, the invention relates to a jack for holding a pin for a hydraulic jack for moving the support, a support system for a solid development system and a method of connecting a hydraulic jack for moving the support with the base of the support section. Jack for holding a pin for a hydraulic jack to move support includes retaining plate and stop. Retaining plate comprises two opposed surfaces and channel with groove between two surfaces. Stop includes a main body, a slot for holding the pin and at least two flanges. Main body is configured to slide into channel groove and passage through surface of retaining plate. Slot for holding the pin has an open inlet through the end of the main body. First flange extends from one end of the main body over the surface of the holding plate, and the second flange extends from the other end of the main body along the other surface of the holding plate. Flanges retain the main retainer body in the first slot from displacement in the direction formed by the longitudinal axis of the slot for holding the pin.
