The invention provides a labor-saving platform lifting mechanism which comprises a rack, a working platform and a lifting combination device, the lifting combination device comprises a motor speed reducer, an air cylinder and a lever type transmission set, and the lever type transmission set comprises a fixed wheel, a movable wheel A, a movable wheel B and a transmission chain. The motor speed reducers are installed on the left side and the right side of the top of the rack respectively and connected with the fixed wheels through transmission output shafts respectively, the driving wheels A are installed on the left side and the right side of the working platform respectively, the air cylinders are installed at the bottom of the rack respectively, pushing rods of the air cylinders are provided with the driving wheels B respectively, and one end of the transmission chain is fixedly connected to the inner side of the rack. And the other end of the transmission chain is sequentially in meshed connection with the A driving wheel, the fixed wheel and the B driving wheel and is fixedly connected to the outer side of the rack. The lifting device is simple in structure and convenient to operate, lifting is carried out according to the lever principle, the power of a motor speed reducer is reduced through large load transmission, and the operation efficiency is improved.

    本发明提供一种省力的平台提升机构,包括机架、工作平台、提升组合装置,提升组合装置包括电机减速机、气缸、杠杆式传动组,杠杆式传动组包括固定轮、A动轮、B动轮和传动链,电机减速机分别安装在机架顶部的左右两侧且其通过传动输出轴分别连接有固定轮,A动轮分别安装在工作平台的左右两侧上,气缸分别安装在机架的底部且其推动杆分别安装有B动轮,传动链的一端头固定连接在机架的内侧,传动链的另一端依次与A动轮、固定轮、B动轮啮合连接并且固定连接在机架的外侧上。结构简单,操作方便,且采用杠杆原理进行提升,使大型的负载传动降低了电机减速机的功率,提高了运行效率。
