Changeable elevator antihunting device of elastic constant

The utility model discloses a changeable elevator antihunting device of elastic constant. It includes upper plate, hypoplastron and the elastic constant first antihunting device for K1, the hypoplastron is fixed on elevator hoisting system's spandrel girder, first antihunting device setting is between upper plate and hypoplastron, still include a n elastic constant for K2's second antihunting device, n >= 1, every second antihunting device is in order can the dismantlement mode installing between upper plate and hypoplastron. The utility model discloses an adopt above -mentioned structure, when taking place resonance phenomenon, only need eliminate resonance phenomenon through increasing the second antihunting device, avoided the complicated mechanic's preface of tearing open, greatly alleviateed dimension guarantor person's intensity of labour, improved work efficiency, reduced the dimension and protected the cost, shortened the maintenance and stopped the ladder time. 本实用新型公开了种弹性常数可变的电梯防振装置。其包括上板、下板和弹性常数为K的
