According to the invention, the advantage that microcracks on the surface layer of the small-size component can be detected by adopting a vibration mode analysis technology is realized. The inventionprovides an intelligent electric speed-control stair-climbing transport trolley for helping the aged. The intelligent electric speed-control stair-climbing transport trolley for helping the aged comprises a manual telescopic module, a transport module and an electric control module. Wheels of the trolley are designed and processed according to the three-star-wheel principle, and the effect of climbing stairs is achieved. With consideration that old people can not pull the trolley conveniently relative to young people, some electric power assisting systems are additionally arranged on the trolley to assist the old people in carrying heavy objects to go upstairs more easily with less burden. In addition, in consideration of poor legs and feet and different walking speeds of the old people, an induction system is additionally arranged on a hand pull handle, the electric speed of the trolley can be controlled according to the stair climbing speed of the old people, and starting and stopping of the trolley can be judged. The anti-toppling trolley is designed for old people, can be effectively prevented from toppling, is simple to operate, high in efficiency, low in cost, time-saving, labor-saving and high in safety, and has very good practicability.

    本发明具有能够实现采用振动模态分析技术检测小尺寸构件表层微观裂纹的优点。本发明提供了一种智能助老电动控速爬楼运输小车。智能助老电动控速爬楼运输小车包括手动伸缩模块、运输模块、电控模块;本发明利用三星轮原理对小车轮子进行设计和处理,实现其爬楼梯的功效。考虑到老人相对于年轻人力气不足以拉动小车,而在小车上加了一些电动的助力系统,辅助老年人更加轻松且更少负担搬运重物上楼梯。并且本发明考虑到老年人腿脚不好,行走速度不一,因此在手拉柄上增添了感应系统,可以根据老年人的爬楼速度对小车电动速度进行控制,以及小车的起步和停止的判断。本发明针对老人设计,能够有效防止小车倾倒,操作简单,效率高成本低廉,省时省力,安全性高,具有非常好的实用性。
