Patent ID: 11827000

Abstract:
Disclosed in the present invention is an auxiliary marking tape laying vehicle for laser scanning of the morphology of a long-span bridge, the laying vehicle comprising a laying portion, a guiding portion and a power transmission portion, wherein the laying portion is fixed on the top of the laying vehicle, a roller is provided on the top of the laying portion, the guiding portion is provided at the bottom of the laying vehicle, the power transmission portion is fixed outside the laying vehicle, a scroll is provided above the guiding portion, the surface of the marking tape in contact with the bridge is a rubber magnetic layer, and the other surface of the marking tape is provided with bulged reflection angles, which are used as teeth to make one end of the marking tape be connected with the roller through the teeth, and to make the other end of the marking tape be connected with the scroll through the teeth. The marking tape is installed at the bottom of the beam of the long-span bridge, and a plurality of bulges formed by the reflection angles of the marking tape are used to provide more reflection surfaces for the laser, to reduce the reflection angle, to improve the reflection effect, and then to improve the efficiency and accuracy of a three-dimensional laser scanner.
