FIXED SUPPORTING LEG AND FRAME CONNECTING STRUCTURE

摘要

There is provided a fixed supporting leg and frame connecting structure for engineering machinery which has fixed supporting leg (10), a frame (30), and a connecting part (50) connected with the fixed supporting leg and the frame. The connecting part comprises a reinforcing vertical board (51). One end of the reinforcing vertical board is fixedly connected with the rear end face of the fixed supporting leg (10) and the bottom surface of the frame (30). The other end of the reinforcing vertical board (51) is fixedly connected with the front end face and the bottom surfaces of the fixed supporting leg (10). The structure reduces the number of welding gaps and stress concentrating points so as to ensure reliable connection and improve connecting strength and rigid. The structure has stable and reliable supporting effect, and increases working efficiency.
