根据工程施工设计和质量要求,对施工工作面的走向、平度、以及断面的水平度都有比较严格的规定,此点在人工渠道和公路修建中尤为明显,这就要求所使用的工程机械应配备有一套能自动导向与定位的装置,以确保工程质量及施工效率。目前国外在工程机械上采用的自动导向装置,大约有三种型式: 一种为激光导向定位装置:如图1,其原理是根据工作面的设计要求,调整固定在地面上的小型激光发射器所发出的扫描线的基准位 According to the construction design and quality requirements of the project, there are strict regulations on the direction, flatness, and level of the construction work surface. This is particularly evident in the construction of artificial channels and roads, which requires the use of construction machinery. Should be equipped with a set of devices that can be automatically guided and positioned to ensure project quality and construction efficiency. At present, there are about three types of automatic guide devices used abroad in construction machinery: One is a laser guide positioning device: as shown in Figure 1, the principle is to adjust small laser transmitters fixed on the ground according to the design requirements of the working face.
