Combined connecting structure for mining excavator chassis and mining excavator
The invention discloses a combined connecting structure for a mining excavator chassis and a mining excavator. The combined connecting structure comprises a double-bearing connecting device and a longitudinal beam upper-portion connecting device. The double-bearing connecting device is mounted at a longitudinal beam side plate. The longitudinal beam upper-portion connecting device is mounted at anupper top plate of the longitudinal beam, the upper portion of a frame connecting plate is connected with the longitudinal beam upper-portion connecting device, and the lower portion of the frame connecting plate is connected with the double-bearing connecting device. By the adoption of the combined connecting structure for the mining excavator chassis and the mining excavator, bolts can be effectively protected, the yield failure is prevented, meanwhile, the overall height of the chassis is reduced, meanwhile, the design height of a frame is not limited, and the overall rigidity of the frameis also improved.
本发明公开了一种矿用挖掘机底盘用组合连接结构及矿用挖掘机，组合连接结构包括双承载连接装置和纵梁上部连接装置；双承载连接装置安装在纵梁侧板处，纵梁上部连接装置安装在纵梁上顶板处，车架连接板上部与纵梁上部连接装置相连，车架连接板下部与双承载连接装置相连。本发明能够有效保护螺栓，防止屈服失效，同时降低底盘的整体高度同时不加限制车架的设计高度，也提高了车架的整体刚度。
