A Ring Rail Crane and Its Running Automatic Deviation Correction System

Abstract

The invention provides a circular track crane and an automatic operation rectifying system thereof. The circular track crane comprises a bridge frame and four sets of operation components arranged at the lower part of the bridge frame; under drive of the four sets of operation components, the circular track crane rotates on a circular track around the axis of the circular track; a circular safety shell is arranged around the circular track on the outer side of the circular track; and the automatic rectifying system comprises at least two sets of information acquiring components respectively used for acquiring operation information of at least two sets of adjacent operation components, a control device for receiving information acquired by the at least two sets of information acquiring components, and four sets of actuation components for respectively driving the four sets of operation components to operate. The automatic operation rectifying system of the circular track crane enables the driving rotating speeds of the four sets of operation components to be different through determining a walking trajectory and an inclined direction of the crane by calculation and adjustment of the control device, so that automatic rectification is finally realized, and the accuracy and the stability of the operation trajectory of the crane are guaranteed.

Description

technical field [0001] The invention relates to an automatic deviation correction system for a crane running, in particular to an automatic deviation correction system for a crane running along a circular track. Background technique [0002] The ring-rail cranes used in nuclear power plants run on the ring-shaped track through the wheels set under the bridge frame. During the operation, due to the actual difference in wheel diameter, the difference in the manufacturing accuracy of the track body, the difference in the installation of the track height, and the difference in the speed of the driving wheel, etc., The running track of the crane will not be an ideal circle, and it will often be biased to one side, prone to adverse phenomena such as rail gnawing or crowding, which will not only cause a lot of economic losses and waste of human resources, but also lead to major safety problems. Contents of the invention [0003] In order to solve the above technical problems, the...
