A three-dimensional terrain-aided mapping device for cities

Abstract

This utility model discloses an urban three-dimensional terrain auxiliary surveying device, relating to the technical field of terrain surveying. The device includes a surveying machine and a base. A rotating assembly is disposed between the base and the surveying machine. Supporting assemblies arranged in a circular array are disposed on the lower surface of the base. The rotating assembly includes a tray, with a first rotating shaft fixed in the center of the tray. The tray drives the surveying machine to rotate 90 degrees, and simultaneously, the tray drives a turntable to rotate via the rotating shaft. A spring force causes a plug to reset and insert into a slot to fix the turntable. This avoids the situation where the device is easily misaligned when adjusting the surveying direction by lifting it, thus achieving the purpose of direction adjustment. By flipping the rotating rod downwards 180 degrees along the hinge connection, and then flipping it again via a torsion spring and a limiting plate, the rotating rod and the support rod are fixedly connected, and a telescopic rod extends from the rotating rod. This avoids the support structure being inconvenient to retract, thus achieving the purpose of convenient storage.
