Abstract

The invention relates to a steel section bending online measurement device and a steel section bending online measurement method. The steel section bending online measurement device comprises a distance measurement unit which comprises a plurality of distance measurement devices, wherein the distance measurement devices are horizontally arranged in a line at equal intervals, a steel end part locating device is arranged in a position which is flush with the distance measurement device at one end of the distance measurement unit, a conveying roller way parallel to the distance measurement unit is arranged in the position opposite to the steel end part locating device and comprises a plurality of parallel conveying rollers, and the distance measurement devices in the distance measurement unit are respectively connected with a computer. The invention further provides a method for measuring the bending online by using the steel section bending online measurement device. The steel section bending online measurement device can easily, intuitively, accurately and efficiently measure the curvatures of different bending situations of the steel, the scope of application is wide, and the bending shape of the steel and the distribution positions of the bending situations can be measured and displayed.

Description

technical field [0001] The invention relates to an on-line measuring device for the bending degree of a section steel and an online measuring method for the bending degree of a section steel, belonging to the technical field of measuring rolled steel products. Background technique [0002] When measuring the bending deviation of H-beam, I-beam, and channel steel, because the traditional measurement method needs to use a long enough wire rope, two workers press the two ends of the steel on the same side respectively, and forcefully Pull to ensure that the wire rope is tensioned as much as possible. At the same time, the third operator uses a steel ruler to visually determine the position where the maximum bending degree is measured, and at the same time visually observes the type of bending of the entire section steel (lateral bending, "S" type bending and local bending at the end, etc.), measure and record the value as the maximum bending degree value of the branch steel. T...
