The invention relates to a basic brake device of a bogie, the bogie and a railway crane, the basic brake device of the bogie comprises two parallel brake beams arranged at intervals and two groups of lever assemblies arranged at intervals, and the brake beams are provided with two groups of connecting fulcrums which are correspondingly connected with the two groups of lever assemblies respectively; each brake beam is provided with a brake shoe, and each brake beam can slide along a slide way arranged on the bogie body and drive the brake shoe to be attached to or separated from a wheel surface; the power end of the lever assembly can be connected with the getting-on pull rod, the lever assembly further comprises a first connecting rod connected with the bogie body, and the getting-on pull rod can act on the lever assembly through the power end and act on the two brake beams through connecting fulcrums correspondingly, so that the two brake beams can slide oppositely along the sliding ways correspondingly. And the brake shoe is driven to be attached to the wheel surface. The foundation braking device can be installed while the self-walking function is guaranteed, the overall braking effect of the railway crane is guaranteed, and safety is improved.

    本发明涉及一种转向架的基础制动装置、转向架及铁路起重机,其中,转向架的基础制动装置包括两根平行且间隔设置的制动梁以及两组间隔设置的杠杆组件,制动梁设有两组连接支点并分别与两组杠杆组件对应连接;各制动梁分别设有闸瓦,且各制动梁能够分别沿设于转向架本体的滑道滑动并带动闸瓦与车轮面贴合或脱离;杠杆组件的动力端能够与上车拉杆连接,杠杆组件还包括与转向架本体连接的第一连杆,上车拉杆能够通过动力端作用于杠杆组件,并通过连接支点分别作用于两根制动梁,使两根制动梁能够分别沿滑道相背滑动,并带动闸瓦与车轮面贴合。能够在保证其具有自力走形功能的同时,安装基础制动装置,保证铁路起重机的整机制动效果,提高安全性。
