Abstract

PURPOSE:To obtain a large-capacity elevator without increasing a braking mechanism under the floor of a cage and reduce a lifting up/down point pit space by installing plural sets of braking mechanisms on a lifting up/down body and mutually linking the operating levers of the braking mechanisms with a longitudinally expandable/contractible linking rod. CONSTITUTION:In the emergency stop device of an elevator, since upper and lower braking mechanisms 25A, 25B are linked with a linking rod 32, as an upper lever 9 is rotated by holding a governor rope 10, a lower lever 9 is also rotated to simultaneously operate the upper and lower braking mechanisms 25A, 25B. Hence, the upper and lower braking mechanisms 25A, 25B may have a braking capacity merely half that of the conventional braking mechanism 25 and can be miniaturized, reducing the space under the floor 5 of a cage. In this case, the linking rod 32 adjusts the timing for upper and lower sliding pieces 16, 17 to be pressed by guide rails 6 so as to agree, while being adjustable by a right-handed screw 32a, a left-handed screw 32b and nuts 33, 34. Also, the timing for the right and left sliding pieces 16, 17 to be pressed by the guide rails 6 is also adjustable by means of links 13.

Rotate this counterclockwise. Therefore, the 1 actuation levers α◆ and a are rotated, the slider a1αη is moved upward on both the left and right sides, and the pressing body 0 is moved while the roller ■ is transferred.
It rises along the slope of σj. As the sliders σQ and αη rise, the gaps between them and the guide surface of the guide rail (6) gradually become narrower 91 until they come into contact with each other. If it rises further, the leaf spring Qυ is pushed open, and the sliders 00 and tin are pressed against the guide surface of the guide rail (6), creating a frictional force between them. This frictional force can be used to brake the heel. This braking force is applied to the guide rail (6) and the slider (Ie).
