Abstract

The present invention relates to a combined counterweight hitching device and method thereof, and a counterweight mounting structure. The combined counterweight hitching device is mounted on a turntable tail framework, wherein the combined counterweight hitching device includes a turntable tail framework bottom plate, a lifting oil cylinder, a lifting oil cylinder fixing seat and a hitching driving mechanism, the turntable tail framework bottom plate is fixed on the turntable tail framework, the lifting oil cylinder fixing seat is arranged on the upper surface of the turntable tail framework bottom plate and is hinged with the turntable tail framework bottom plate, the lifting oil cylinder is fixed at one end of the lifting oil cylinder fixing seat, the one end distal to a point on which the turntable tail framework bottom plate is hinged with the lifting oil cylinder fixing seat, a hitching platform is mounted at a piston rod end of the lifting oil cylinder, and the hitching driving mechanism is connected with the lifting oil cylinder fixing seat, and drives the lifting oil cylinder fixing seat to make the hitching platform enter a hitching platform groove on the counterweight to complete a hitching operation. By adopting the combined counterweight hitching device and method, and the counterweight mounting structure provided by the present invention, the mounting and demounting of the combined counterweight are more convenient, and the mounting space is smaller.
