Deviation rectifying method, device and system for tire crane

Abstract

The invention relates to a method, a device and a system for correcting deviation of a tire crane. A video image shot by a camera is received when correcting deviation of the tire crane: when the tirecrane advances along an advancing route with a guide color band, the camera shoots an image of the guide color band in an advancing area of the tire crane in a preset reference view finding frame; image processing is performed on the video image to obtain current position information of a guide color band in the video image in the reference view finding frame; the current position information iscompared with reference position information of a reference guide color band in the reference view finding frame, and when the current position information is different from the reference position information, that the tire crane has deviation is determined and a deviation value of the tire crane is determined; and the deviation value of the tire crane is sent to a tire crane operation control system, so that the tire crane operation control system corrects the deviation of the tire crane. Automatic deviation rectification of the tire crane is achieved.

Description

technical field [0001] The invention relates to the control field of hoisting equipment, in particular to a deviation correction method, device and system for a tire crane. Background technique [0002] The tire crane is a gantry crane that uses a tire-type chassis to walk. It is equipped with a lifting mechanism, a cart traveling mechanism, and a trolley mechanism. When the tire crane is running, it is necessary to ensure that it does not deviate from the guide ribbon set on the ground to ensure the smooth implementation of the lifting operation. When the tire crane system deviates, it is necessary to correct the tire crane. At present, the driving of the tire crane is mainly controlled by the driver. The driver visually checks the parallelism between the hoisting part of the tire crane and the guide ribbon set on the ground, so as to judge whether the tire crane has deviated. If so, perform manual control , to adjust the driving position of the tire crane. [0003] At p...

Problems solved by technology

This method is simple and reliable, and the investment cost is low, but the application is limited

It is more suitable for the electric tire crane that has adopted the trolley line of the bottom frame, that is, the tire crane that has been equipped with a bracket. For other tire crane usage occasions, since the bracket needs to be erected on one side of the tire crane's driving route, the civil construction will be harmful to the tire. The impact on the occasion of crane use is relatively large, and the cost is relatively high
