A conveying and loading integrated bench, model test system and working method

Abstract

The present disclosure provides an integrated conveying and loading bench, a model test system and a working method, which relate to the field of model tests, and include a frame, wherein six directions of the frame are respectively matched with corresponding loading plates, and a lifting arm is used to adjust a loading plate position, so that the loading space can be opened on one side, cooperate with the conveying mechanism to receive the specimen from the open position, and transport the specimen to the loading space, the loading process can be carried out after the lifting arm returns to the initial position, and the loading process of the whole specimen is convenient , the loading and position adjustment process of the specimen can be completed without dismantling the bench, which meets the needs of existing loading experiments.

Description

technical field [0001] The present disclosure relates to the field of model testing, in particular to an integrated transport and loading platform, a model testing system and a working method. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] The underground engineering model test is an effective method and means to simulate the underground engineering and guide the design and construction of the 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 been gradually established; many large-scale engineering projects have carried out geomechanical model tests and obtained a large number of research results. [0005] The inventor found that with the increas...

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
