Universal chassis foundation

The invention discloses a universal chassis foundation, which comprises a chassis main body composed of four same chassis block assemblies, and a plurality of mounting holes are formed in the chassis block assemblies; the standard knot base is provided with a connecting structure embedded in the mounting hole and a connecting part used for connecting the standard knot; the two cross beam assemblies are arranged on the two sides of the underframe main body; the guide rail is connected to the chassis main body; and the introduction trolley is arranged on the guide rail. One chassis foundation can be used for electric derricks of multiple models, the universality of the chassis foundation is guaranteed, the standard knot base does not need to be fixed through bolts, and the chassis disassembling and assembling efficiency is improved. 本发明公开一种通用型底架基础，包括：底架主体，由四个相同的底架块组件组成，所述底架块组件上设有若干安装孔；标准节底座，设有嵌入安装孔设置的连接结构和用于连接标准节的连接部；两个横梁组件，设置于底架主体两侧；导轨，连接于底架主体上；引进小车，设置于导轨上。本发明实现一个底架基础可用于多个型号的电力抱杆，保证其通用性，且标准节底座无需通过螺栓固定，提高了底架拆装的
