AI Technical Summary
The existing grab buckets for diaphragm wall trenching machines are inconvenient to position and lack operational stability, resulting in low construction efficiency and a tendency to vibrate or deviate.
A hydraulic grab bucket comprising a support plate, support frame, adjustment components, and stabilization components was designed. Through the combination of gears, cylinders, and connecting rods, the grab bucket's position can be flexibly adjusted and stably supported, enhancing the flexibility and stability of construction.
It improves the convenience of grab bucket position adjustment and construction efficiency, reduces shaking and offset, and enhances construction stability and efficiency.
