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.

First claim

The invention claimed is:

1. An auxiliary marking tape laying vehicle for laser scanning of a 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 a top of the laying vehicle; a roller is provided on a top of the laying portion; the guiding portion is provided at a bottom of the laying vehicle; the power transmission portion is fixed outside the laying vehicle; a scroll is provided above the guiding portion; a surface of the marking tape in contact with the bridge is a rubber magnetic layer; and an 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 an other end of the marking tape be connected with the scroll through the teeth;
the laying portion comprises a bracket; and the bracket comprises a lower plate which is horizontally arranged, and a side plate which is connected with the lower plate at an acute angle; an elastic part is fixed at an angle between the lower plate and the side plate; the roller is installed on a top of the side plate through a rotating shaft, and the lower plate is fixed on the laying vehicle through a tightening bolt;
the guiding portion is connected with a bottom of a vehicle body through slots, and is fixed at the bottom of the vehicle body through a first bolt; the guiding portion is symmetrically arranged on both sides of the bottom of the laying vehicle; and guiding wheels are provided inside the guiding portion;
a plurality of running wheels are symmetrically arranged at the bottom of the vehicle body; two symmetrical running wheels in a middle are connected with a gear set, and the gear set is connected with the scroll which is disposed above the gear set; and the marking tape is wrapped around the scroll,
wherein the marking tape is made of a flexible material, the surface where the reflection angles are located is densely covered in white; and the shapes of the reflection angles are an equilateral triangle.

2. The auxiliary marking tape laying vehicle for laser scanning of the morphology of a long-span bridge according to claim 1 , wherein the power transmission portion comprises a transmission rod and a magnet, one end of the transmission rod is fixed on an outer end face of the vehicle body through the first bolt, and an other end of the transmission rod is connected with a magnet.

3. The auxiliary marking tape laying vehicle for laser scanning of the morphology of a long-span bridge according to claim 1 , wherein the elastic part is a torsion spring.
