Intelligent lifting appliance based on acoustic surface waves

Abstract

The invention discloses an intelligent lifting appliance based on acoustic surface waves. The intelligent lifting appliance comprises a lifting plate, a main lifting rope, a lifting ring and auxiliarylifting ropes; acoustic surface wave tension sensors are arranged on the auxiliary lifting ropes, one end of each auxiliary lifting rope is detachably connected with the lifting plate, the other endsof the auxiliary lifting ropes are connected with the lifting ring, the lifting ring is connected with the main lifting rope, and the main lifting rope is connected with an overhead travelling crane;the intelligent lifting appliance further comprises an acoustic surface wave reader and a control display unit, the acoustic surface wave reader is connected with the acoustic surface wave tension sensors and used for reading tension values measured by the acoustic surface wave tension sensors; and the control display unit is connected with the acoustic surface wave reader, and when the acousticsurface wave reader reads the tension values, the control display unit collects and displays the tension values read by the acoustic surface wave reader. According to the intelligent lifting appliancebased on acoustic surface waves, passive wireless measurement for lifting rope tension of the lifting appliance product can be realized, and safety, accuracy and data traceability in lifting assemblywork are improved.

Description

technical field [0001] The invention relates to the technical field of precision hoisting and assembly, in particular to an intelligent hoisting device based on surface acoustic waves. Background technique [0002] In the process of product hoisting and assembly, a rope-type three-hook spreader or four-hook spreader is generally used to connect the product to be hoisted, and then the assembly is realized in the form of crane transfer. In the hoisting assembly, especially in the special precision hoisting assembly operation, there are many problems and risks in the traditional rope-type spreader. [0003] First of all, the stress state of the product is unknown during the hoisting process, and it is impossible to judge the overload situation in time, and there is a relatively large safety risk; secondly, during the assembly process, the stress state of the product can only be judged by the obvious looseness of the lifting rope, and it is impossible to judge the product in a t...

AI Technical Summary

Problems solved by technology

[0003] First of all, the stress state of the product is unknown during the hoisting process, and it is impossible to judge the overload situation in time, and there is a large safety risk; secondly, during the assembly process, the stress state of the product can only be judged by the obvious looseness of the lifting rope, and it is impossible to judge the product in a timely and accurate manner. The position is stressed, which is not conducive to precision assembly; thirdly, the service life of the spreader is judged by the wear of the wire rope, and the early wear of the product cannot be accurately identified. In the field of special assembly, the safety is insufficient; finally, with the continuous expansion of product quality traceability requirements , the use of spreaders plays an important role in data support for product quality traceability, traditional spreaders cannot achieve history traceability, which is not conducive to product quality control

[0004] At present, some spreaders use the traditional tension sensor to measure the tension of the rope. However, due to the limitation of the hoisting conditions of the crane, the power supply of the sensor can only be powered by battery, which leads to the large size of the sensor, limited use time and frequent replacement. Batteries are not conducive to the long-term maintenance-free use of spreader products
