Problems solved by technology

[0003] The auxiliary take-off test load of a new type of carrier-based aircraft in my country is a single point large load, reaching more than 180 tons, and the load direction is obliquely downward. Compared with simple vertical load and horizontal load, the test load is more difficult. The fixed equipment and the load-bearing floor of the factory building have brought great challenges, and the existing load-bearing devices are far from meeting the use requirements.

Embodiment Construction

[0030] The purpose of the invention is to provide a large tonnage load bearing device. The device requires a compact and lightweight structure for easy transport and test installation; it requires strength and rigidity to meet certain requirements to ensure the safety and accuracy of the test. It is required to realize the active unloading of the directional component of the auxiliary take-off load and the floor diffusion of the vertical component to ensure the safety of the load-bearing floor and fixed equipment of the test plant.

[0031] The invention is mainly realized by the following technical scheme: based on the characteristics of the auxiliary take-off test load of a new type of carrier-based aircraft, the large-tonnage load-carrying device adopts an integral welded structure of steel plates, and the integral welded structure is set for the course component of the test load Active unloading interface to safely unload the main course component of the test load to the d...

Abstract

The invention provides a large-tonnage load bearing device. The device comprises a vertical integral welding structure 1, a hydraulic equipment interface 2, a horizontal integral welding structure 3,a butt joint reinforcing rib 4 and an active unloading interface 5, wherein the vertical integral welding structure 1 comprises a first panel, a second panel and at least two vertical rib plates whichare vertically arranged between the first panel and the second panel, two transverse rib plates which are transversely arranged at the two ends between the first panel and the second panel, the firstpanel and the second panel are each of a square plate-shaped structure, a through hole is formed in the area, close to the top, of each vertical rib plate, and the through holes are used for hoistingthe device. A hydraulic equipment connector 2 is arranged on the outer side of the first panel, is of a hole group structure and is used for being in butt joint with hydraulic equipment.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a large-tonnage load bearing device. Background technique [0002] In the structural strength test of the aircraft, it is necessary to use the load bearing device to safely transfer the test load applied to the aircraft structure to the bearing structure (bearing floor, bearing wall, etc.) of the test workshop. In previous models of aircraft structural strength tests, distributed loads (such as wing loads) can be controlled by partitions to adjust the load at the loading point, and concentrated loads (such as landing gear loads and engine loads) are also on the order of tens of tons. This relatively small load does not have high requirements on the existing hardware conditions of the full-machine test plant. The strength of the existing typical load-carrying device meets the requirements. The load on the load-carrying device is spread in a small range through pressure beams a...
