Abstract

The invention discloses a loading test device. The loading test device comprises a support framework, a positive loading device and a lateral loading device; the support framework comprises a top frame, a base and two vertical side frames; the positive loading device is positioned between the two side frames, the height of the positive loading device is adjustable, and a loading end at the lower part of the positive loading device can move up and down and move little in the side direction; and the lateral loading device is positioned at the lower part of the positive loading device, is connected with the loading end and moves up and down together with the movement of the loading end. Through the loading test device provided by the invention, positive loading and lateral loading can be simultaneously realized for a static or moving device to be tested; and the loading test device has simple structure, is easy to manufacture and operate, and is suitable for testing various vertical lifting jacking devices.

Description

technical field [0001] The invention relates to a loading test device, in particular to a loading test device for testing the performance of various vertical lifting jacking devices under loading conditions. Background technique [0002] In the field of large-scale equipment manufacturing, it is often necessary to test the safety and reliability of the designed products. By intentionally applying a certain external load to the product sample, and the external load can simulate the stress condition of the product in actual use, the performance of the product can be effectively verified, thereby avoiding possible problems in actual use. [0003] Taking an aircraft jack as an example, it is an important lifting device used for maintenance and repair of large equipment such as aircraft. In order to verify whether the designed aircraft jack can meet the requirements of relevant technical specifications and ensure the safety and reliability of use, each aircraft jack must be subj...
