SHIFTING TABLE Russian patent published in 2018 - IPC B65G63/02 B65G67/04 

FIELD: transportation.

SUBSTANCE: shifting table contains a platform 1 with vertical rollers 2 on its sides and a pushing double-sided shield 3 that is low and placed on four saddle rollers fixed to vertical axes mounted on its lateral sides with an offset from its lateral sides and supported by triangular guides 6 located at the edges of the platform 1. The ends of the ropes 7 and 8 are fixed in the center of the platform 1, placed in a trough-like tray and thrown over blocks 10 and 11 installed on the supports along the ends of platform 1 and connected to a drum of a reversible two-rope winch 13 located on a frame 14 attached with stands 16 and struts 17 to the bottom of bearing beams 15 in the middle of the platform 1. There are smooth non-driven rollers 20 made without ledges and with supports lowered in grooves above the platform between the upper longitudinal beams. The coupling mechanisms are made in the form of double-armed levers and installed on both sides along the edges of the platform 1. The two-arm levers are paired and articulated by short ends with a screw with right and left thread. A flywheel is installed at one end of the screw. For lifting and lowering the platform 1, four vertical screw mechanisms with ball supports are attached to its supporting beams 15, standing on L-shaped brackets and connected in pairs by a tubular connection and reinforced with struts 33. Cargo ears are arranged on platform 1 sides for its transfer by crane and installing on the track by brackets. There are limit switches installed on the edges of the platform 1 to stop the double-sided shield 3.

EFFECT: increase rigidity of the platform and simplify manufacturing of individual units, their maintenance and operation.
