The invention discloses a counterweight device of an elevator and a stacked counterweight pressing piece of the counterweight device, and relates to the technical field of elevator counterweights. A first disc is in chain transmission connection with an upper first roller and a lower first roller on the left side, and a second disc is in chain transmission connection with an upper second roller and a lower second roller on the right side; a first magnetic pin and a second magnetic pin are inserted into a first disc and a second disc in a sliding mode respectively, the counterweight is driven to move substantially when the counterweight device ascends and descends abnormally and rapidly, so that magnets installed at the upper end and the lower end of the counterweight attract the first magnetic pin magnetically and repel the second magnetic pin magnetically; the first magnetic pin and the second magnetic pin move to limit rotation of the first disc and the second disc respectively, so that rotation of the first roller and the second roller is limited, rolling friction of the counterweight device in the guide rail is changed into sliding friction, friction resistance is increased, auxiliary braking is achieved, and the service life of the counterweight device is prolonged. And the safety of the elevator in the running process can be effectively improved.

    本发明公开了一种电梯的对重装置及其层叠配重按压件,涉及电梯配重技术领域,本发明通过将第一圆盘与左侧上下两个第一滚轮链传动连接,将第二圆盘与右侧上下两个第二滚轮链传动连接,并将第一磁性销和第二磁性销分别滑动插接在第一圆盘和第二圆盘内,借助对重装置异常快速升降时驱使平衡块的大幅度移动,使得安装在平衡块上下端头位置的磁石对第一磁性销磁性吸引,对第二磁性销磁性相斥,使得第一磁性销和第二磁性销移动后分别对第一圆盘和第二圆盘进行旋转限制,进而限制第一滚轮和第二滚轮的旋转,使得对重装置在导轨内的滚动摩擦改变为滑动摩擦,增大摩擦阻力,实现辅助制动,可以有效提升电梯运行过程中的安全性。
