Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0022] As shown in the figure, the load-bearing device is connected to the load-bearing foundation through connecting bolts 1 and round pins 2 on the two legs 4, ensuring axial fastening and lateral positioning. The load-bearing device is connected to the product through several connecting bolts 6 and load-bearing pins 9, among which high-strength bolts are used for axial fastening, and the tight fit of load-bearing pins and pin holes is used to bear lateral loads and eliminate lateral displacement.

[0023] The load-bearing device has a maximum load capacity of 100t and adopts a box-shaped structure. The main structure includes an annular center 5 and two outriggers 4 . The frame structure of the ring center is composed of panels 10, arc risers 11, ring risers 12, side plates 13, and ribs 14 are evenly arranged inside. The plates are we...

Abstract

The invention discloses a planar annular heavy load force bearing device for a liquid rocket power system test. The device comprises two supporting legs, an annular center and a built-in moving supporting plate nut. The annular center is connected with a product, and the two supporting legs are connected with a force bearing foundation. The beneficial effects of the planar annular heavy load force bearing device for the liquid rocket power system test are that a force bearing ring satisfies a requirement for fixing of a module with zero height difference between butt joint height and a pivot through arrangement of a plane beam structure. The force bearing ring adopts the structural form of the two supporting legs and the annular center, is linearly concise and attractive, and is uniform in stress distribution. Steel plates of different thickness are adopted to weld to construct a box-shaped structure, can satisfy a requirement for hundreds of tons of bearing capacity, and can also reduce weight. By adoption of the prearranged moving supporting plate nut, position-adjustable nut prearrangement in the box-shaped structure is realized, and the problem of bolt tightening and installation in the box-shaped structure is solved. Axial fastening is realized by adoption of a high-strength bolt, and a lateral load is borne and lateral displacement is eliminated by adoption of close fit of a force bearing pin and a pin hole.

Description

technical field [0001] The invention is a plane annular load-bearing device for a test of a liquid rocket power system, which can meet the installation and fixation requirements of a module with a zero-height difference between the docking height and the fulcrum, meet the requirements of a hundred-ton coupling dynamic load, and meet the requirements of large-scale structural parts. High precision assembly requirements. Structural design suitable for heavy-duty foundations. Background technique [0002] The load-bearing device is the direct carrier of the test force of the liquid rocket power system. It needs to bear various loads such as rocket thrust, wind force, and impact during the test, and transfer these loads to the load-bearing foundation. With the development of heavy-duty, modularized and serialized transportation, the requirements for bearing capacity and structural flexibility of bearing rings are getting higher and higher. The rated thrust of the liquid rocket...
