A load-bearing and connecting device at the fixed end of a UAV test bench

Abstract

The invention discloses a fixing end bearing and connecting device for an unmanned aerial vehicle test bed. The fixing end bearing and connecting device comprises a movable grid plate component, a bearing framework and a rotating disk. The movable grid plate component is connected with the bearing framework, and the movable grid plate component and the bearing framework jointly bear the weight of a tested unmanned aerial vehicle. The bearing framework and the rotating disk are connected, and universal wheels are arranged at the lower end of the rotating disk. The movable grid plate component comprises two movable symmetrical grid plates, a lead screw shaft, a grid plate sliding supporting frame, a middle plate and limiting devices. Each movable grid plate comprises two symmetrical slidable limiting devices. The grid plate sliding supporting frame is arranged on the bearing framework. The limiting devices can slide along an undercarriage groove so as to adapt to undercarriages with different lengths. The lead screw shaft is arranged in the middle of the movable grid plate component, the middle plate is arranged at the middle end of the bearing framework, and the limiting devices are arranged at the end points of the undercarriage groove.

Description

technical field [0001] The invention relates to a load-bearing and connection device for a fixed end of an unmanned aerial vehicle test bench. Background technique [0002] Unmanned helicopters have been vigorously developed in civilian fields such as electric power, geological surveys, and agriculture. Unmanned helicopters carry pods, pesticide spraying systems, etc., which can ensure that tasks required in various fields are performed at an appropriate time and power inspections are completed in a timely manner. , geological survey, pesticide spraying and other tasks. [0003] UAVs have become the development focus of future civilian operations. In order to ensure the performance of UAVs used in various fields is qualified, it is bound to become a key point to test the performance indicators of UAVs. [0004] At present, there is no special equipment to test the performance of UAVs, only through flight tests, which requires a large airspace and reduces safety. [0005] T...
