Large-load high-speed goods elevator car frame structure

The invention relates to the related technical field of goods elevator car frame structures, and discloses a heavy-load high-speed goods elevator car frame structure which comprises a car frame, the car frame comprises an upper fixing frame and a lower fixing frame, and the upper fixing frame and the lower fixing frame are connected through a plurality of straight beams. The lower fixing frame comprises a first portal frame lower beam and two second portal frame lower beams which are horizontally distributed at intervals. The stability and the bearing capacity of the car frame are effectively improved by adopting a cornice-like structure and an inhaul cable structure in the car frame, an interactive laminated structure is adopted in the car bottom platform, the bearing capacity of the split car bottom bracket and the car bottom platform is improved, meanwhile, an air spring and rubber spring combined structure is further adopted in the car bottom platform, and therefore the stability and the bearing capacity
