Description
Technical field
This utility model relates to high-altitude operation vehicle, specifically a kind of working bucket Weighing mechanism being applied on high-altitude operation vehicle.
Background technology
Along with life and produce be continually changing and develop, the application of high-altitude operation vehicle is more and more extensive, arrange at building, house ornamentation, electric operating, megastore, large-scale cultural and sports activity site facility and install, light rail and bridge construction, many aspects such as the regular maintenance of main equipment such as aircraft etc. and cleaning play more and more important effect. Along with application is increasingly wider, working environment also becomes increasingly complex, in order to adapt to various severe operating mode, it is ensured that Operation Van safe and reliable, is necessary for the structure of high-altitude operation vehicle is continuously improved and innovative design.
High-altitude operation vehicle is when carrying out work high above the ground, and people stands in operation inside working bucket. The load weight of working bucket includes people and the weight of entrained instrument. Because body weight and the different areas of activity of people are different, load weight is also usually different, if load weight is a lot of beyond the weight of design, then likely produce security incident, therefore, for ensureing the use safety of Operation Van, it is necessary to the weight of working bucket load is monitored.
And existing high-altitude operation vehicle is weighed, scheme is divided into two classes mostly, and a class is that four corners arrange four sensors, the another kind of side being LOAD CELLS is contained in working bucket bottom working bucket, allows working bucket be connected either directly through LOAD CELLS with jib assembly. But above-mentioned two class schemes have obvious limitation, first kind measurement result is relatively accurate, but Weighing mechanism is taken up space relatively big, and working bucket is difficult to make dismountable structure, and this can significantly increase the collection size of Operation Van. In today of high-altitude operation vehicle collection cun increasingly miniaturization, such as in the occasion requiring over narrow and small door entrance office work, this scheme just cannot meet requirement. The position that Equations of The Second Kind scheme is then stood due to people in working bucket is different, causes that loading moment is different, hardly results in measurement result accurately, and if LOAD CELLS accident failure damage, there is also certain potential safety hazard.
In order to adapt to produce and the live change and demand maked rapid progress, it is necessary for the structure to Operation Van and carries out constantly improving and innovating.
Summary of the invention
