Problems solved by technology

For example, aircraft, satellites, etc., due to the requirements of large target load, many structural restrictions, high positioning accuracy, and high safety requirements, there is no relatively mature equipment in China for experimental measurement
Most of the current measurement methods are simple function tests on the ground after simplifying the working conditions, which greatly affects the evaluation of the use function of specific targets

Abstract

The invention belongs to the technical field of aerospace heavy equipment testing, and relates to a large-scale heavy-duty support lifting system; it is composed of a support frame and a mobile platform, a counterweight frame and a counterweight platform, a support rod assembly and a wire rope pulley seat assembly; The motor drives the gear box on the mobile platform, and the rack and pinion structure drives the entire mobile platform to go up and down in the vertical direction at a long distance; For the movement of two degrees of freedom, the designed lifting stroke can reach 13m, and the designed horizontal movement stroke can reach 1m; in order to ensure the stability and safety of lifting, a counterweight platform is added to balance the overall weight of the mobile platform and the load; the horizontal movement is The lead screw is driven by the servo motor to move the support rod assembly in a short horizontal stroke at a low speed; the system is characterized by large load capacity, high motion precision, and high operational safety and stability.

Description

technical field [0001] The invention belongs to the technical field of aerospace heavy equipment testing, and in particular relates to a large-scale heavy-load supporting lifting system. Background technique [0002] In the experimental testing process in the field of aerospace, in order to measure the important parameters of some specific targets, it needs to be lifted and lowered in the vertical direction with a long stroke to meet the requirements of the target's pose change in the high-altitude state. For example, aircraft, satellites, etc., due to the requirements of heavy target load, many structural restrictions, high positioning accuracy, and high safety requirements, there is no relatively mature equipment for experimental measurement in China. Most of the current measurement methods are simple function tests on the ground after simplifying the working conditions, which greatly affects the evaluation of the use function of specific targets.
