Problems solved by technology

However, due to the limitation of the experimental conditions in the physical similarity simulation experiment, that is, the scaling effect on the actual engineering conditions, many steps operated by humans in actual work are difficult to realize manually, which requires some special devices to replace manual , in order to realize the actual engineering conditions, so there is this kind of hydraulic support moving device

Abstract

The invention relates to engineering field physical simulation of mine, rock soil and the like and especially relates to a hydraulic support shifting device applied to a physical similarity simulation test. The device comprises one preposition connection portion and a plurality of postposition shifting portions. The preposition connection portion comprises a plurality of first top bearings, a first upper belt, a plurality of first bottom bearings, three fixing components, a lock catch, a first lower belt, a U type fixing component and a first support body. Each postposition shifting portion comprises a plurality of second top bearings, a second upper belt, a plurality of second bottom bearings, a third concave clamping groove plate, a third convex clamping groove plate, a second lower belt, a connection portion and a second support body. The preposition connection portion is plugged with the adjacent postposition shifting portion, and the two adjacent postposition shifting portions are plugged.

Description

technical field [0001] The invention relates to physical simulation in engineering fields such as mines and geotechnical fields, and in particular to a hydraulic support moving device applied to physical similarity simulation tests. Background technique [0002] Physical similarity simulation experiment technology has been developed for nearly a century since the former Soviet Union. It is of great significance to the measurement and reference of relevant data in actual engineering. It has solved many data problems caused by unmeasured or difficult measurement in actual engineering. shortage problem. [0003] Physical similarity simulation experiment is one of the important research methods of mining, geotechnical, geology and other disciplines. It can be used to simulate various actual engineering geological conditions, and provide various information for support, working face stress and strain, and surrounding rock stability changes in engineering practice. kinds of param...
