The invention discloses a sling swing angle detection device and a sling bridge crane. The detection device is used for detecting the swing angle state of a sling, and the sling is suspended through a lifting rope; the detection device comprises a supporting platform and a sliding platform, and the vertex angle positions of the supporting platform are each provided with a supporting piece; the bottom of each supporting piece is provided with a piezoresistive pressure sensitive element; the sliding platform is rectangular, first sliding blocks are arranged on the two long edges of the sliding platform separately, and second sliding blocks are arranged on the two wide edges of the sliding platform separately; the first sliding blocks and the second sliding blocks are further connected to the piezoresistive pressure sensitive elements through elastic assemblies; the lifting rope is swung to drive the first sliding blocks and/or the second sliding blocks to move, and the corresponding elastic assembly generates elastic force; and the elastic force is applied to the piezoresistive pressure sensitive element, and therefore the resistance value of the piezoresistive pressure sensitive element is changed.
本发明公开了一种吊具摆角检测装置和吊具桥式吊车,用于检测吊具的摆角状态,所述的吊具通过吊绳悬吊,包括:支撑平台,其顶角位置处分别设有一支撑件,所述支撑件底部设有压阻式压力敏感元件;滑动平台,其为矩形,所述滑动平台的两个长边上分别设有第一滑块,且所述滑动平台的两个宽边上分别设有第二滑块;第一滑块和第二滑块还通过弹性组件连接于压阻式压力敏感元件;吊绳摆动,带动第一滑块和/或第二滑块运动,并使得对应的弹性组件产生弹力,该弹力施加于压阻式压力敏感元件,使得压阻式压力敏感元件的电阻值变化。
