The utility model provides a kind of steel structure building installation positioning device, belong to steel structure building construction technical field.The device structure is ingenious, and it is good to guide, it is convenient to clamp, can be flexibly disassembled, it is convenient for engineering construction use.The electric hoist of the device is fixedly installed on the one side board surface of fixed plate, and a plurality of fixed length's pull cable are fixedly connected on the other side board surface of fixed plate, the free end of each fixed length's pull cable is fixedly bolted screw rod, the drum of electric hoist is wound pull cable, and the free end of pull cable on electric hoist is scattered into multiple strands, and the free end end of each pull cable is fixedly bolted clamping assembly.The device clamps more stable, and the pulling capacity is stronger, and the guiding stability is high, and the alignment accuracy is high, and the assembly construction safety is improved.

This utility model relates to a universal chassis, including a chassis body, a base plate, and an outer shell on top of the base plate. An inner frame is located inside the outer shell, with casters at the four corners of the bottom of the inner frame. Two mounting plates extend downwards from the center of the inner frame, with drive wheels mounted on the mounting plates via drive components. A slot is provided on the rear side of the outer shell, housing a battery module. Two charging contacts are located on the rear side of the battery module. A depth camera is located on the front top of the outer shell, and two lidar sensors are located diagonally on the top of the outer shell. A lifting slot is located on the rear side of the battery module, with a rotating pull ring within it. The angle difference between the depth camera and the outer shell is 45°. The lidar sensors in this utility model are divided into forward and backward types. The backward lidar is specifically designed for rapidly approaching moving obstacles (such as pedestrians and vehicles) to perform velocity vector analysis. Combined with forward lidar data, collision time can be predicted, supporting robots to perform reversing avoidance or path replanning, making the chassis safer and more flexible in dynamic environments, with a detection range covering 360°.
