The invention particularly relates to a positioning auxiliary device for hoisting a steel truss. The device is characterized by comprising an acoustic wave and laser composite range finder transmitting device (1), a laser range finder receiving device (2), a three-dimensional scanner (3) and a computer (4), wherein the sound wave and laser composite range finder transmitting device (1) is installed on a truss column foot, the laser range finder receiving device (2) is installed on a truss support, and the three-dimensional scanner (3) and the computer (4) are used in a handheld mode. In the hoisting process of the large truss, the relative position relation between the truss and surrounding obstacles can be controlled in real time, real-time position detection of the truss and the surrounding obstacles is achieved, even if the column foot of the truss is located in a view blind area, the column foot of the truss can still be prevented from colliding with the surrounding obstacles or rubbing the surrounding obstacles through the method and the actual field operation, and the hoisting safety of the large truss is improved. And the safety and the stability in the hoisting process are ensured.
本发明具体是一种钢桁架吊装的定位辅助装置;其特征是:声波激光复合测距仪发射装置(1)、激光测距仪接收装置(2)、三维扫描仪(3)和计算机(4);其中,声波激光复合测距仪发射装置(1)安装于桁架柱脚上,激光测距仪接收装置(2)安装于桁架支座上,三维扫描仪(3)、计算机(4)为手持使用。本发明可在大型桁架吊装过程中,实时控制桁架与周围障碍物的相对位置关系,实现桁架与周围障碍物的实时位置检测,即使桁架柱脚处于视野盲区,通过本发明及现场实际操作,仍可使其不与周围障碍物发生磕碰、剐蹭等情况,保证了吊装过程的安全性和稳定性。
