Problems solved by technology

In the past, anti-skid schemes were usually formulated at the test site according to the load at the loading point and the limitation of the ground space on the site. Most of these schemes were based on practical experience. They were random and uncertain, and did not achieve the purpose of pre-design. At the same time, it also increases a lot of on-site repetitive work.

Abstract

The invention provides a device for limiting a vertical column to prevent slippage. The device is characterized by comprising a supporting base (1), an adjustment screw rod (2) and an antiskid top plate (3), wherein one end of the adjustment screw rod penetrates through the supporting base and is vertically mounted on the end face of the supporting base through threads, and the other end of the adjustment screw rod is vertically connected with the rear end face of the antiskid top plate in a rotatable manner; the front end face of the antiskid top plate is fitted with the vertical column; the lower end face of the antiskid top plate is fitted with the ground.

Description

technical field [0001] The invention aims at the anti-slip problem of the loading column installed vertically to the ground rail in the static test of the ground strength of the aircraft structure, and designs a ground anti-skid device for the loading column, which is mainly used to prevent the sliding between the loading column and the ground during the test loading process and cause the test Decreased stability, or problems with unexpected aborts of load control system out-of-tolerance protection tests. Background technique [0002] During the test loading process, due to the unexpected sliding of the loading column, the loading equipment deviates from the original design coordinate position, which affects the accuracy of the test loading, and then affects the accuracy of the test data; when the test load is large, the sudden sliding of the loading column may cause the loading of the control equipment Over-tolerance protection, the test was terminated unexpectedly. During...
