AI Technical Summary

Technical Problem

Existing scrap steel delivery tank trucks have problems such as high risk of manual operation during unloading, slow unloading speed, easy blockage, rigid impact between wheels and rails due to track settlement, and unstable operation, which affect the conveying efficiency and safety.

Method used

The unloading gate is moved synchronously in opposite directions by a linkage gear and double rack structure driven by a servo motor. Combined with a shock absorption system of piston rod, hydraulic sleeve and disc spring, it ensures that the unloading gate opens quickly and the wheels adjust adaptively, avoiding shaking caused by scrap steel accumulation and uneven track.

Benefits of technology

It enables rapid and smooth unloading of scrap steel, improves unloading efficiency and safety, ensures close contact between wheels and rails, and enhances equipment stability and conveying safety.
