System for testing comprehensive performance of beam column nodes of goods shelf

Abstract

The invention relates to a system for testing the comprehensive performance of beam column nodes of a goods shelf, and the system comprises two rack upright columns, a top beam, a mechanical body unit, a hydraulic control unit, and a data processing and analyzing unit, wherein the mechanical body unit is mainly formed by four parts, namely a beam-column combination member mounting device, a hydraulic cylinder mounting and moving device connected with the hydraulic control unit, a crossbeam clamping device and a sidewise restraining fixture; the beam-column combination member mounting device is a vertical worktable provided with a flexible upright column clamping mechanism; the flexible upright column clamping mechanism is fixedly provided with an upright column; the hydraulic cylinder mounting and moving device is mounted at the inner part of the top beam; the lower part of a hydraulic cylinder is connected with a connecting rod; the bottom end of the connecting rod is hinged with a cross beam vertically-clamping device; the upper end surface and the lower end surface in the cross beam vertically-clamping device, which are close to a cross beam, are respectively provided with a pressure sensor; and one end of the cross beam is connected with the upright column, and the other end of the cross beam is mounted on the sidewise restraining fixture. By adopting the system, comprehensiveness, flexibility, error compensation and quantitative analysis can be realized on the nodes of the goods shelf.

Description

technical field [0001] The invention relates to the technical field of performance testing of shelf connectors, in particular to a comprehensive performance testing system for shelf beam-column joints. Background technique [0002] Shelves generally refer to shelves used to store goods, and in warehouse equipment, they refer to storage equipment specially used to store items. With the expansion of the demand for highly automated production in modern industries, three-dimensional warehouses have emerged, which increase storage density and transshipment efficiency, speed up the turnover of goods and funds, improve operating conditions, and increase economic benefits. Traditional shelves are mostly welded or bolted with section steel (channel steel, angle steel and steel pipe, etc.). At the end of the 1980s, a new type of shelf emerged. The beam and the column of the shelf were connected by a mechanical locking device, and it was a detachable assembled shelf. It uses rolled o...

AI Technical Summary

Problems solved by technology

[0006] (1) The performance test of beam-column joints is not comprehensive, and there are blind spots in test analysis

[0007] (2) The test device is not flexible enough, only for a certain series of products

[0008] (3) There is no compensation function for errors

[0009] (4) Only qualitative analysis is used for the failure mode of beam-column joints
