ROTATION SHAFT ASSEMBLY FOR SCISSORS-TYPE BUCKET APPARATUS WITH IMPROVED ASSEMBLY AND SCISSORS-TYPE BUCKET APPARATUS HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2016/052829
Kind Code:
A1
Abstract:
The present invention relates to a rotation shaft assembly for a scissors-type bucket apparatus which, to cross-link a pair of scissors arms so as to be rotatable, adopts a sliding-and-rotation type rotation member with easy disassembly and replacement instead of a bearing which is permanently fixed, and which minimizes the number of components to maximize the assembly thereof, and a scissors-type bucket apparatus having the same, said rotation shaft assembly for a scissors-type bucket apparatus comprising: an installation pipe fixed to a first scissors arm; a rotation member comprising a bush fixed to the installation pipe and a rotation wheel installed so as to be slidably rotatable relative to the bush; a central shaft connected to an end of the rotation shaft in a straight line passing through the rotation wheel, a second scissors arm and an auxiliary arm so as to rotate along with the rotation wheel, the second scissors arm and the auxiliary arm; a fixation ring which is configured to be force-fit into a gap formed between the outer circumferential surface of an end part of the rotation shaft and the second scissors arm; a cover plate which is configured to pressurize the fixation ring from the outer side surface of the second scissors arm to be force-fit; a plurality of longitudinal axis pins which are installed in the circumferential direction of the central shaft, said plurality of longitudinal axis pins passing through the auxiliary arm, the rotation wheel, and the second scissors arm to the cover plate to be assembled together; and pressurization nuts which are connected to the front ends of the longitudinal axis pins to fix the longitudinal axis pins and cause the cover plate to pressurize the fixation ring.
