A vertical mechanical model material thin layer cutting device

Abstract

The invention relates to a vertical mechanical model material thin layer cutting device. The vertical cutting mode is adopted, uploading can be conducted by directly utilizing a pressure testing machine, so that the manpower and material resources are more saved; meanwhile the range of model material blocks (soft-hard extent) capable of being cut is wider; the model material blocks are vertically cut, so that the two side faces of the model material blocks are supported by side plates, and the surface of an obtained thin layer is ensured to be flatter; compared with a steel wire, an adopted plastic-steel wire has the characteristics of being small in weight, easy to bend, high in tensile force and free of corrosion and is easy and convenient to mount; the homogeneity of the obtained thin layer of the same material is good, the interface is flatter, and the discreteness of testing data can be effectively avoided; a vertical linear cutting frame adopts a split type structure, and dismounting of the front side wall and taking-out of sheets are facilitated; and the vertical linear cutting frame directly takes a material box as a support, a base is omitted, and the structure is lightened and simplified.

Description

technical field [0001] The invention relates to the technical field of multi-interbedded rock mass simulation tests, and more specifically relates to a vertical mechanical model material thin-layer cutting device, which uses a set of parallel plastic steel wires to cut the model material into multiple thin slices at one time, and is widely used It is used to prepare thin slices of multi-interbedded rock mass model materials. Background technique [0002] In the fields of underground engineering, mining engineering, and slope engineering related to rock mechanics, there are a large number of problems related to layered rock mechanics related to sedimentary rock formations. Relative to the engineering scale, these layered rock masses can be considered as multi-layered rock masses. Since the multi-interbedded rock mass is a natural layered material composed of a variety of different properties, different thicknesses, different components and different combinations in a certain...

Problems solved by technology

However, this device has the following disadvantages in the actual operation process: 1) Since the loading method is manual loading, on the one hand, it is a waste of manpower and material resources; on the other hand, the model material can only be cut manually under soft conditions, so the conditions There are restrictions; 2) Since the loading method is horizontal loading, during the cutting process, the three sides of the cut model material block need to be kept in the empty state, so it is easier to cause extrusion deformation on the side of the model material block, resulting in thin layers Uneven and uneven surface; 3) Due to the high rigidity of the steel wire used, it is difficult to easily wrap around the screw hole of the cutting frame
