A chain wheel type manual top cover opening and closing device belongs to the technical field of railway wagons and comprises a speed reducer, a clutch, an input chain wheel assembly, a conversion chain wheel assembly, an output chain wheel assembly and a top cover rotating mechanism which are sequentially connected. A large conversion chain wheel and a small conversion chain wheel which are arranged side by side are fixedly connected to the first chain wheel shaft, the large conversion chain wheel is rotationally connected with the input chain wheel through a first chain, and the small conversion chain wheel is rotationally connected with the output chain wheel through a second chain. The chain wheel type transmission device is simple in structure, convenient to install and maintain, small in chain wheel transmission resistance, high in transmission efficiency during manual operation and small in torque loss; meanwhile, when the automatic device works, the passive rotation resistance of the chain wheel is small, and energy loss is small; the device is arranged at the end of the vehicle body, the vehicle body volume can be effectively enlarged, and load is increased.

    一种链轮式手动顶盖开闭装置,属于铁路货车技术领域,包括依次连接的减速机、离合器、输入链轮组成、转换链轮组成、输出链轮组成及顶盖转动机构,所述转换链轮组成包括第一底座,所述第一底座上轴承连接有第一链轮轴,所述第一链轮轴上固定连接有并排设置的转换大链轮和转换小链轮,所述转换大链轮通过第一链条与输入链轮组成转动连接,所述转换小链轮通过第二链条与输出链轮组成转动连接。本发明中,链轮式传动装置结构简单,安装维护保养方便,链轮传动阻力小,手动操作时传递效率高,力矩损耗小;同时,自动装置工作时,链轮被动转动阻力小,能源损失小;且装置设置在车体端部,可有效扩大车体容积,增加载重。
