[0003] At present, the bending deformation of the boom is detected in real time by the measurement method of the jib disturbance. This measurement method is usually used in test measurements rather than engineering products, mainly by measuring one or two reference points on the single jib section of the crane.

The invention provides a method for detecting a contour of a crane boom. The method comprises the steps that a plurality of baffles protruding out of the crane boom are arranged in the extending direction of the crane boom at intervals and a scanner is arranged between every two adjacent baffles; the crane boom and the baffles are scanned through the scanners so that a plurality of contour points can be obtained, wherein a scanning range of each scanner exceeds the adjacent baffles arranged at the two sides of the scanner and the scanning resolution of each scanner is that at least two contour points are respectively obtained from the adjacent baffles on the crane boom and the two sides of each scanner; according to the contour points, baffle contour lines of the adjacent baffles at the two sides of each scanner and crane boom contour lines of the portions, between the adjacent baffles, of the crane boom are obtained, and therefore local contour lines can be formed; the local contour lines are spliced with the baffle contour lines serving as a standard. Through the method, the accuracy of contour line measurement can be improved.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a method for detecting the contour of a crane jib. Background technique [0002] During the hoisting process of the crane, or the telescopic, slewing, and luffing process of the boom of the crane, due to the large lifting capacity of the crane, the long boom, and the large bending deformation of the boom, it is necessary to perform real-time detection of the bending deformation of the boom , to prevent safety accidents caused by excessive deformation of the boom. [0003] At present, the bending deformation of the boom is detected in real time by the measurement method of the jib disturbance. This measurement method is usually used in test measurements rather than engineering products, mainly by measuring one or two reference points on the single jib section of the crane. Displacement or inclination, the measurement accuracy is low. Contents of the invention [0004] The ...
