However, the current design of the grid grid anti-hook mechanical experimental equipment can test a single working condition, without considering the influence of various factors on the grid grid anti-hook performance, and cannot fully simulate the actual hoisting. The unfavorable effects on the grid frame during the process lead to a large deviation between the test results and the actual situation

The invention discloses a device for testing the anti-hooking performance of grid frames. The device is mainly used for simulating the possible collision and friction between the grid frames in the actual installation process, and for testing the contact surface of the two grid frames. The friction force and the displacement of the grid frame are collected to facilitate the evaluation of the anti-hooking performance of the grid frame. Due to the uncertainty of the angle and speed of the collision and friction of the grid frame during the actual installation process, the present invention designs a slide table that can adjust the contact angle and contact position between the static test piece and the moving test piece, and the installation can Servo-controlled electric cylinder system to adapt to various working conditions.
Description
technical field [0001] The disclosure relates to a device for testing the anti-snaking performance of a grid frame, which can be used to test the mechanical properties of the anti-snap of the grid frame under various working conditions. Background technique [0002] The grid is made up of multiple grids with the same size and circular cross-section. These grids are grouped according to a certain number and placed in multiple grids, but the distance between these grids is very small , There may be collisions and frictions during installation. In severe cases, the outer wall of the grid will be deformed or torn, resulting in the destruction of the grid, which will bring great safety hazards and economic losses. Therefore, the anti-hook performance of the grid must be tested during the design to prevent the occurrence of the hook phenomenon during the actual installation process. [0003] The grid frame anti-hook mechanical experiment is to simulate the possible collision and ...
