Problems solved by technology
In the existing technology, the vehicle-mounted platform is prepared by casting or steel plate welding process, which has problems such as large weight, low specific stiffness and poor dynamic characteristics.
The weight of the vehicle-mounted platform is too large, which seriously affects the transportation of the platform, and puts forward higher requirements for the carrying capacity of the vehicle
Insufficient rigidity will lead to excessive deformation of the platform and affect the measurement accuracy of theodolite
The poor dynamic characteristics of the platform are mainly manifested in the fact that the base frequency is too low, which will limit the servo control bandwidth of the warp and weft, and then affect the servo control of the warp and weft

The invention discloses a vehicle-mounted theodolite supporting platform. The vehicle-mounted theodolite supporting platform comprises a platform supporting frame, a platform skin, a device installingboss, a platform supporting leg transferring member and a platform supporting leg assembly. The platform skin covers the platform supporting frame, the device installing boss is arranged on the platform supporting frame, the platform supporting frame is a rectangular frame welded by metal pipes, and cable-stayed rods are arranged in the rectangular frame according to the transfer path of force based on results of topological optimization. The platform supporting leg assembly is arranged below the four top corners of the platform supporting frame, and the platform supporting leg transferring member is arranged at the joint of the four top corners of the platform supporting frame and the platform supporting leg assembly. The vehicle-mounted theodolite supporting platform can guarantee the supporting stiffness of the vehicle-mounted platform and realizes the lightweight of the vehicle-mounted platform on the premise of fundamental vibrational frequency.
Description
technical field [0001] The invention relates to the technical field of shooting range optical measurement, in particular to a vehicle-mounted theodolite support platform. Background technique [0002] With the development of shooting range optical measurement technology, the non-ground measurement of vehicle-mounted theodolite has become a research hotspot. The photoelectric theodolite is installed on a liftable platform, and is transported to the designated place by a vehicle. The outriggers lift the platform carrying the theodolite to a certain height, so that the theodolite is separated from the vehicle, so as to realize the measurement without landing. In order to ensure the measurement accuracy, the high stiffness and dynamic stability of the vehicle platform are extremely important. In the prior art, the vehicle-mounted platform is manufactured by casting or steel plate welding process, which has problems such as large weight, low specific stiffness and poor dynamic c...
