Torque loading device for cloth tape on moving foot stopper

Abstract

The invention discloses a torque loading device for a cloth tape on a moving foot stopper. The torque loading device includes a main supporting frame (9), and a cloth tape fixing swithover block (5) is arranged below the top of the main supporting frame (9). The bottom of the cloth tape fixing swithover block (5) is fixedly connected with a cloth tape (11) on the upper portion of a moving foot stopper (1) that needs to be loaded with torque; the central position of the top of the main supporting frame (9) is provided with a circular through hole (90), a torque transmission structure for transmitting an externally applied torque is arranged in the through hole (90), the lower portion of the torque transmission structure is fixedly connected with the top of the cloth tape fixing swithover block (5), and the torque transmission structure is in linkage connection with a transversely arranged actuator (2). The torque loading device can safely and reliably exert a torque on the flexible cloth tape on the upper portion of the moving foot stopper, and the problem of force loading point and force loading direction movement occurring when the torque is applied to the cloth tape is effectively solved.

Description

Technical field [0001] The invention relates to the technical field of mechanical tests, in particular to a torque loading device for a cloth belt on a movable foot limiter. Background technique [0002] At present, for the manned space module, in order to ensure that it can meet various conditions, it is necessary to conduct a static load test on the movable foot stopper installed in the manned space module to test the ability of the products installed in the manned space module to withstand static loads , So as to obtain carrying capacity data to provide support for product design, research and development, and finalization. [0003] Among them, for the movable foot limiter installed in the manned space capsule, the upper part has a flexible cloth belt, and torque is usually applied to the flexible cloth belt, so that the movable foot limiter manufacturer can further detect the movable foot limit When the device is loaded with torque, whether it will be deformed or damaged.

Problems solved by technology

[0004] For the existing torque loading device, it usually only directly loads the flexible cloth belt with the upper part of the moving foot limiter, and the specific form of loading is that an iron rod passes through the cloth belt to apply torque. During the torque process, it is found that there will be slippage between the cloth belt and the iron rod, which will lead to the movement of the force loading point and the force loading direction, resulting in inaccurate and difficult loading of the load

[0005] Therefore, there is an urgent need to develop a device that can safely and reliably apply torque to the flexible cloth belt on the upper part of the moving foot limiter, and effectively solve the force loading point and force loading direction movement that occurs when torque is applied to the cloth belt.
