Title:
PANTOGRAPH HEAD BALANCING STRUCTURE OF PANTOGRAPH HAVING SMALL ROTATION ANGLE, PANTOGRAPH HEAD AND DESIGN METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/091442
Kind Code:
A1
Abstract:
A pantograph head balancing structure of a pantograph having a small rotation angle, a pantograph head and a design method thereof. The method optimizes the rotation angle of a pantograph head by means of relative position parameter coordinates of hinge points of a pantograph, well developed dynamics software, and an integrated database of general optimization algorithms, so as to significantly reduce a declination angle of the pantograph head, such that the pantograph head achieves a state of near horizontal motion within a working range of the raising and lowering of the pantograph. The invention increases the surface area of contact between the pantograph and a catenary, thereby improving the quality of a current collected by the pantograph, and reducing damage to the pantograph and the catenary.
