Conveying and loading integrated rack, model testing system and working method

Abstract

The invention provides a conveying and loading integrated rack, a model testing system and a working method, and relates to the field of model testing. The conveying and loading integrated rack comprises a framework. Cooperating and corresponding loading plates are arranged in the six directions of the framework. The position of one loading plate is adjusted through a lifting arm, one side of loading space can be open, and test pieces are received from the open position by cooperating with a conveying mechanism and are conveyed into the loading space; and after the lifting arm resets to the initial position, the loading process can be carried out, the whole test piece loading process is convenient, the process of loading and position adjusting of the test pieces can be completed without dismounting the rack, and the requirements of existing loading testes are met.

Description

technical field [0001] The present disclosure relates to the field of model testing, in particular to a conveying and loading integrated platform, a model testing system and a working method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The underground engineering model test is an effective method and means for simulating underground engineering and guiding the design and construction of underground engineering. The model test mainly includes the model test bench device, loading system, similar materials, measuring components and other parts. [0004] Structural model tests have been carried out in the industry, and similar theories have gradually been established; many large-scale engineering projects have carried out geomechanical model test research, and a large number of research results have been obtained. [0005] The inventor...

AI Technical Summary

Problems solved by technology

[0005] The inventors found that with the increase of the number of underground engineering constructions, the scale is also increasing, and the model test itself is also becoming larger and larger, and its stress conditions and test conditions are becoming more and more complicated; during the model test time In the process of installation and loading, there are many inconveniences. When installing model test specimens on traditional model test benches, it is necessary to disassemble the bench, then load the specimens, install and restore the position of each loading module; after each disassembly Calibration of the loading module and bench is required; on the one hand, the accuracy of the test piece with a large volume and weight cannot be guaranteed when loading, and it is difficult to accurately adjust the position with an external sling, and the operation is easy to interfere with other components; on the other hand, Before and after disassembly and assembly, the accuracy of the loading module is difficult to guarantee, and the calibration of the loading position needs to be re-calibrated, which makes the loading operation complicated and inefficient, and has a great impact on the subsequent loading process; on the other hand, the handling of the traditional test bench and The loading is relatively complicated, and the function of the test bench is single, and it is impossible to realize the integration and coordinated operation of transportation and loading; it is difficult to meet the existing needs for loading tests on large-volume and complex stress specimens
