The invention relates to an elevator, a speed limiting device installation structure and a lifting mechanism. The lifting mechanism comprises a main transmission shaft, a first driven shaft and a second driven shaft, the first driven shaft and the second driven shaft are both in rigid connection with the main transmission shaft, the first driven shaft and the second driven shaft are oppositely arranged in a spaced manner, and the first driven shaft and the second driven shaft are arranged on the same side of the main transmission shaft. Compared with a traditional mode that a connecting rod isadopted for transmission, the first driven shaft and the second driven shaft are both in rigid connection with the main transmission shaft, virtual displacement is eliminated, transmission losses donot exist, and it is further guaranteed that safety tongs corresponding to the first driven shaft and safety tongs corresponding to the second driven shaft can rapidly and synchronously work; and thestructure of the lifting mechanism is simplified, and the mounting space is saved.

    本发明涉及一种电梯、限速装置安装结构及提拉机构,其中,提拉机构包括主传动轴、第一从动轴及第二从动轴,所述第一从动轴及所述第二从动轴均与所述主传动轴刚性连接,所述第一从动轴与所述第二从动轴相对间隔设置,且所述第一从动轴与所述第二从动轴设置于所述主传动轴的同一侧。相比传统的采用连杆进行传动的形式而言,第一从动轴与第二从动轴均与主传动轴刚性连接,消除了虚位移,不存在传动损失,进一步保证与第一从动轴对应的安全钳和与第二从动轴对应的安全钳能够快速的同步工作,也简化了提拉机构的结构,节省安装空间。
