Abstract

The patent for the invention belongs to the field of double girder crane devices, and particularly discloses a micro deformation detection device of a double girder crane trolley. The micro deformation detection device of the double girder crane trolley comprises laser emitters and photosensitive receiving lattices which are mounted at the two ends of steel girders on both sides of the double girder crane trolley correspondingly; each photosensitive receiving lattice comprises a plurality of photosensitive audions connected with a micro controller through an interface circuit; each interface circuit is an and gate circuit with a plurality of diodes in parallel connection; and the micro controller obtains the position information of a plurality of laser radiation points according to laser light signals received by the photosensitive receiving lattices, obtains the offset distance information of the corresponding laser radiation points according to the position information and spaces between the adjacent photosensitive audions, and obtains the offset angle information of the corresponding laser radiation points according to the offset distance information. By means of the technical scheme, micro deformation of the double girder crane trolley is precisely detected, and the rail gnawing phenomenon of the crane trolley is avoided.

Description

technical field

[0001] The patent of the present invention relates to the field of double-girder crane devices, in particular to a micro-deformation detection device for a double-girder crane trolley. Background technique

[0002] Double-girder cranes generally refer to double-girder bridge cranes. Double-girder bridge cranes are important tools and equipment for mechanization and automation of the production process in modern industrial production and lifting transportation. Therefore, double-girder bridge cranes are widely used in indoor and outdoor industrial and mining enterprises, It is widely used in iron and steel chemical industry, railway transportation, port terminals and logistics turnover and other departments and places. As a commonly used large-tonnage hoisting machinery, double-girder cranes occupy an important position in the hoisting industry.

[0003] Double-girder cranes are generally composed of three major parts: mechanical, electrical and metal structu...
