Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] Figure 1-Figure 3 Among them, the vertical positioning ruler 1 is connected with the horizontal positioning ruler 2 through the card slot, so that the horizontal positioning ruler 2 can move freely in the axial direction and play the role of longitudinal positioning; the upper and lower parts of the horizontal positioning ruler 2 pass through the sliding groove 6 connection, the upper part can freely move laterally along the sliding groove 6 to achieve lateral positioning; the angle locator 3 and the crack positioning panel 4 are fixed on the upper part of the lateral positioning ruler 2, and can move laterally along the sliding groove 6 along with the upper part; The preset crack piece is placed on the positioning panel 4, which can rotate around the central axis to achieve angular positioning. It can be seen that the application of this devic...

Abstract

The invention relates to a three-dimensional crack space positioning device, which includes a longitudinal positioning ruler, a lateral positioning ruler, an angle locator and a crack positioning panel. Free movement in the longitudinal direction plays the role of longitudinal positioning; the horizontal positioning ruler is composed of upper and lower parts connected by sliding grooves, and the upper part can move freely along the groove horizontally to achieve lateral positioning; the angle locator and crack positioning panel are fixed on the The upper part of the lateral positioning ruler can move laterally along the chute along with the upper part; the pre-set crack piece placed on the crack positioning panel can rotate around the central axis to achieve angular positioning. It can be seen that the application of this device can realize the longitudinal, transverse and angular positioning of the crack positioning surface (pre-set crack position), and the height direction positioning can be realized by changing the height of the positioning ruler. The invention has the advantages of simple structure, convenient use, accurate positioning and the like.

Description

technical field [0001] The invention relates to a positioning device, in particular to a three-dimensional crack space positioning device. Background technique [0002] We know that the expansion and evolution of three-dimensional cracks have always been the main content of rock mechanics. At present, the indoor test is the main research method to study the propagation law of three-dimensional cracks. The method of making three-dimensional cracks is mainly realized by pre-embedding polyester sheets in the process of making test pieces. The accurate positioning of three-dimensional cracks (inclination angle, spatial position, etc.) ) is the key to the success of the test (the basis for analyzing the test results). However, at present, in the three-dimensional crack test and the location of the three-dimensional crack, the method of visual inspection is mostly used, and there is no special accurate three-dimensional crack spatial location device. Contents of the invention ...
