The invention belongs to the technical field of pantographs, and particularly relates to a lifting structure for a pantograph. The pantograph seat is arranged on the base in a lifting manner and is used for mounting a pantograph; the connecting rod structure is used for connecting the base and the pantograph seat; the damping adjustable telescopic structure is arranged in the connecting rod structure and used for buffering when the connecting rod structure stretches or folds, the damping adjustable telescopic structure is filled with magnetic fluid, the magnetic fluid is magnetically connected with an elastic electromagnetic part, and the elastic electromagnetic part is arranged between the base and the pantograph seat; the driving part is used for driving the connecting rod structure to stretch or fold, and the driving part is arranged on the base. The device generates a magnetic field through the elastic electromagnetic part, and the magnetofluid changes the viscosity under the action of the magnetic field so as to realize resistance change.
本发明属于受电弓技术领域,尤其涉及一种受电弓用升降结构,包括:底座;电弓座,可升降设置在底座上,电弓座用于电弓安装;连杆结构,用于底座与电弓座之间连接;阻尼可调伸缩结构,设置在连杆结构内,用于连杆结构伸展或折叠时缓冲,阻尼可调伸缩结构内填充有磁流体,磁流体磁性连接有弹性电磁部,弹性电磁部设置在底座与电弓座之间;驱动部,用于驱动连杆结构伸展或折叠,驱动部设置在底座上。本装置通过弹性电磁部产生磁场,磁流体在磁场作用下改变黏度进而实现阻力变化。
