The invention relates to a wedge block for elevator safety tongs, a preparation method and the elevator safety tongs, the wedge block comprises a wedge block base body, one side of the wedge block base body is provided with a working face, the working face comprises softening areas and hardening areas, the softening areas and the hardening areas are adjacent in pairs, one hardening area is arranged between every two adjacent softening areas, and the hardness of the hardening areas is larger than that of the softening areas. Thus, according to the wedge block provided by the invention, the mode that the softening areas and the hardening areas are adjacently arranged in pairs are formed on the working face, and one hardening area is arranged between every two adjacent softening areas, so that the working face of the wedge block base body forms the mode that the soft phases are combined with the hard phases, and the hard phases play a cutting effect when the wedge block is rubbed; and the soft phase is responsible for absorbing external energy, stabilizing the friction coefficient and superposing double effects through deformation and adhesion effects during friction of the wedge block, so that the surface strength can be improved, the friction coefficient of the working surface of the wedge block can be improved through plastic deformation, the service life of the wedge block is prolonged, and the safety of an elevator is higher.

    本申请涉及一种电梯安全钳用楔块、制备方法及电梯安全钳,包括楔块基体,楔块基体一侧具有工作面,工作面包括软化区及硬化区,软化区与硬化区两两相邻,且每相邻两个软化区之间设有一个硬化区,其中,硬化区的硬度大于软化区的硬度。如此,本申请提供的楔块,在工作面形成两两相邻设置软化区和硬化区的方式,且每相邻两个软化区之间设有一个硬化区,使得楔块基体工作面形成软相加硬相相结合的方式,硬相在楔块摩擦时起到切削效应,软相在楔块摩擦时负责变形与黏附效应吸收外界的能量,稳定摩擦系数,双效应叠加,这样既可以提高表面强度,又可以通过塑性变形改善楔块工作表面的摩擦系数,从而增加楔块的使用寿命,使得电梯安全性更高。
