AI Technical Summary

Technical Problem

Existing flatbed transport trolleys have significant deficiencies in steering performance, braking effect, storage capacity and structural practicality, making them unsuitable for operation in narrow passages and inconvenient to use.

Method used

It adopts a six-wheel structure, including a base, a detachable base plate assembly, a brake assembly, an elastic element and a pressing assembly. The bottom of the base is equipped with a universal wheel set and a directional wheel set. The brake assembly realizes linkage braking, and the pressing assembly can switch the wheel set status to improve steering flexibility and parking safety.

Benefits of technology

It enables the trolley to turn 360 degrees and move flexibly in narrow passages, improves braking stability and storage convenience, and enhances its adaptability in places such as supermarkets and warehouses.

Abstract

The present application relates to the technical field of logistics vehicle, especially to a six-wheel carrying trolley, which comprises a base, a bottom plate assembly, a brake assembly, an elastic member and a pressing assembly. The bottom of the base is sequentially arranged with a first universal wheel group, a directional wheel group and a second universal wheel group, and the wheel bottoms of the two universal wheel groups form a driving plane. The bottom plate assembly is detachably installed on the base, and the brake assembly is composed of a brake pedal, a brake link group and a brake lever, which can realize linkage braking of the directional wheel group. When the bottom plate assembly is lowered, the bottom plate pressing yoke drives the directional wheel group to move downward through the pressing link group, and the wheel bottoms contact the ground, so that the whole wheel body can normally carry and push. After the bottom plate assembly is detached, the elastic member drives the directional wheel group to lift and suspend, and only the universal wheel group contacts the ground, which is convenient for flexible turning in narrow space. The present scheme has compact structure, and can realize carrying driving, linkage braking and flexible turning function, and is convenient for storage and use, which is suitable for the operation requirements of supermarkets, warehouses and other scenes.
