The invention discloses a small manned working bucket load detection device, which comprises a working bucket, a stress bottom plate, an elastic telescopic mechanism for connecting the stress bottom plate with the working bucket and a detection switch arranged between the working bucket and the stress bottom plate, and is characterized in that the elastic telescopic mechanism is used for supporting the distance between the working bucket and the stress bottom plate; the distance between the working bucket and the stress bottom plate is changed according to the stress conditions of the elastic telescopic mechanisms, each elastic telescopic mechanism comprises a screw, a nut and a stress spring, the elastic telescopic mechanisms are evenly arranged at the bottom of the working bucket, the stress springs are compressed after the working bucket bears the load, and the stress springs are deformed; the device is simple and reliable in structure and convenient to install, the load limiting function of the operation bucket can be achieved without using a controller and a force sensor, the cost is low, data acquisition and comparison are not needed, direct triggering is achieved, and responsiveness is high.
本发明公开一种小型载人工作斗载荷检测装置,包括:作业斗、受力底板、将受力底板与作业斗连接的弹性伸缩机构以及设置在作业斗与受力底板之间的检测开关,弹性伸缩机构用于支撑作业斗与受力底板的距离,使作业斗与受力底板之间的距离根据弹性伸缩机构的受力情况而变化,弹性伸缩机构包括:螺杆、螺母、受力弹簧,通过作业斗底部均匀布置弹性伸缩机构,利用工作斗承重后压缩受力弹簧产生受力弹簧形变,受力弹簧压缩后作业斗受力底板下移触碰检测开关即为超载,进而进行一系列安全限制,本装置结构简单可靠,安装方便,无需使用控制器及力传感器即可实现作业斗载荷限制功能,成本低,无需经过数据采集对比,直接触发,响应性高。
