Integrated synchronous sliding forepoling of reversed loader

The integrated synchronous sliding forepoling of the reversed loader comprises an inner frame and an outer frame, the interval width of a left row of stand columns and a right row of stand columns of the forepoling is set according to the width of the reversed loader, the reversed loader is arranged between the two rows of stand columns, and the reversed loader and the stand columns of the inner frame or the outer frame are fixed together. The lower end of the stand column fixed to the reversed loader is designed to be in a ball head cylinder bottom type and is connected with a column socket of the reversed loader. The lower ends of the other stand columns are designed to be flat-bottomed and make contact with a roadway bottom plate. The reversed loader is connected with one or more forepoling frames, the forepoling frames move synchronously, and the forepoling frames step and move automatically alternately at the same time. Integrated synchronous moving of the forepoling and the reversed loader is achieved,
