Problems solved by technology

There are many disadvantages in this measurement method, for example, it does not take into account the elastic deformation of the sling, nor does it consider that after the sling is wound on the shaft, the circumference of each loop of the sling is not directly equal to the circumference of the shaft

Abstract

The invention discloses a measuring device for the synchronous error of a double-lifting-appliance bridge crane based on photoelectric sensing. The measuring device comprises a first synchronous measuring part, a second synchronous measuring part, a signal measuring integration module and a computer. The first synchronous measuring part is arranged at the bottom of a trolley mechanism and used fordetecting the motion state of a first lifting rope; the second synchronous measuring part is arranged at the bottom of the trolley mechanism and used for detecting the motion state of a second lifting rope; the input end of the signal measuring integration module is connected to the first synchronous measuring part and the second synchronous measuring part, and used for processing the motion state of the first lifting rope and the motion state of the second lifting rope; and the input end of the computer is connected to the signal measuring integration module and used for obtaining the motiontime of the first lifting rope and the motion time of the second lifting rope according to the motion state of the first lifting rope and the motion state of the second lifting rope correspondingly,the corresponding first motion length and the corresponding second motion length of the measuring device for the synchronous error of the double-lifting-appliance bridge crane based on photoelectric sensing are obtained by combining the rotating speed of a first lifting motor and the rotating speed of a second lifting motor, and finally, the synchronous error is obtained.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for the synchronous error of a bridge crane with double spreaders based on photoelectric induction. Background technique [0002] The double-slinger bridge crane is a new type of port container site lifting equipment. It has two lifting spreaders, which can lift two 40-foot or four 20-foot containers at a time, which is different from the traditional single crane. Compared with the bridge crane, the loading and unloading efficiency of the container is greatly improved. The double spreader bridge crane has the performance of load interlocking, and the double spreader is required to run synchronously and coordinately when loading and unloading goods. However, due to the different characteristics of the hoisting motors of the bridge crane, as well as the coupling effect between the spreaders and external interference and friction, errors occur between the double spreaders, an...
