The invention belongs to the technical field of crane lifting appliance detection, and provides a crane lifting appliance swing angle detection device which is composed of a base, a batten, a rope and a rope tensioning device. According to the method, the rope mounted between the lifting appliance and the moving end of the crane is additionally arranged, a set of detection system is matched, and the swing angle change of the lifting appliance of the crane is indirectly calculated by detecting the bending deformation of the batten due to stress in the swing process of the rope. Different from other devices for detecting displacement variation caused by swinging, the detection end of the device does not have a large number of moving parts, the durability is higher, the manufacturing cost is relatively low, and installation is convenient.
Description
technical field [0001] The invention belongs to the technical field of crane spreader detection, and relates to a device for detecting a swing angle of a crane spreader. Background technique [0002] The crane in the prior art, especially the bridge crane, in the process of transporting goods, due to the existence of the flexible body structure of the steel cable, often causes the operation of the spreader and the bridge crane trolley to be out of sync, so the swing of the spreader occurs. The problem makes it possible to collide with other objects around it, which affects the working efficiency of the crane to a certain extent. Therefore, the detection of the swing angle of the crane spreader is very important for the swing control of the crane spreader. In addition, the detection technology of the swing angle of the crane spreader is also very important for the automation transformation and intelligent control technology of the crane. [0003] The existing invention techn...
