ELECTROMECHANICAL LIFTING DEVICE WITH THE MECHANISM OF ACTUATION THE LIMIT SWITCH Russian patent published in 2018 - IPC E04H12/18 E04H12/34 B66F3/10 

FIELD: transportation.

SUBSTANCE: electromechanical load-lifting device with the mechanism of activation of limit switches (ELD) is intended for installation of a payload on it. The characteristic features of the ELD are that its sections are formed by profiled vertical posts with a rectilinear lateral generatrix located axially symmetrically. The adjacent sections of the arrays of their pillars are mutually unfolded around the axis, and the elements of the lower and upper centering and fixation from rotation about the axis of each movable section are conjugated to the vertical struts of the adjacent section along their profile, with the possibility of shifting this movable section in the axial direction. Furthermore, ELD is fitted with the original mechanism for activating the limit switches, which contains a spring-loaded hinged lever based on ELD with a possibility of interaction when driving up to the extreme limit switch the upper sections of the regulations and, accordingly, when driving down-with the extreme lower position limit switch sections, with the articulated lever connected which is installed vertically with the ability to move up/down along a common axis sections hour skipped into the holes of the lower parts of all movable sections of ELD. On the mentioned stand, two protrusions are provided, with the possibility of interacting each of them with the lower part of the corresponding extreme movable section of the ELD.

EFFECT: rapid lifting and lowering of the load to the specified height.
