Device for installing middle belt frame of crawler-type self-moving machine

The invention discloses a device for mounting a middle belt frame of a crawler-type self-moving machine, which comprises at least two supporting vertical rods, a belt supporting plate, a mounting supporting plate, a supporting plate, a conveying hydraulic oil cylinder, a mounting mechanism, a driving mechanism and a driving mechanism, the supporting device is used for moving forwards in the direction perpendicular to the roadway under the driving of the conveying hydraulic oil cylinder so as to support the carrier roller fixing frame of the middle belt frame, and is further used for bearing the carrier roller fixing frame to move backwards in the direction perpendicular to the roadway under the driving of the conveying hydraulic oil cylinder. The carrier roller support frame is aligned and fixed with the mounted carrier roller fixing frame on the left side; manual installation of the middle belt frame is replaced, the production efficiency is improved, the labor intensity is relieved, and the installation tim
