Description
Technical field
The utility model relates to a kind of contactless displacement measuring device, is particularly useful for the displacement measuring device of rock stratum mobile phase like each measuring point in the simulated experiment.
Background technology
The mankind obtain by the underground mining mode obtaining mostly of mineral resources.Along with to the increase of demand for energy and continuing to increase of mining rate, the superficial part resource reduces day by day, and the degree of depth of underground mining is increasing.With the colliery is example, and the China's coal-mine mining depth increases with the speed of annual 8～12m, estimates will enter into the degree of depth of 1000m to 1500m in following 20 years a lot of collieries of China.Increase along with mining depth, geologic condition worsens, fragmented rock body increases, terrestrial stress increases, water yield strengthens, temperature rise, cause promoting that difficulty strengthens, operating environment worsens, the roadway support difficulty increases, the rapid a series of problems such as increases of aeration-cooling and production cost, for deep resource exploitation has proposed serious challenge.At present, the experience of China aspect deep mining also relatively is short of, and the research of for this reason carrying out the deep mining gordian technique has important meaning.Wherein, the problems such as mobile and subsidence of superincumbent stratum are one of them important topics under the deep mining situation.
The experimental study means of the problems such as mobile and subsidence of superincumbent stratum mainly are to carry out the analog simulation experiment under the deep mining situation at present, and the method can more effectively obtain moving and the subsidence rule of rock stratum.In this experiment, the sinking displacement amount of different measuring points normally utilizes the transit point-to-point measurement on the measurement model.Often need to measure the deflection of thousands of measuring points in experiment, transit is the pointwise hand dipping, and time-consuming bothersome, workload is very big.And, must in the process of experiment, carry out coordinate and the measurement of azimuth that each is measured during measurement, this process need cost plenty of time.
The utility model content
The utility model is in order to overcome weak point of the prior art, a kind of efficiency of measurement height to be provided, and is convenient and swift, contactless, can move the displacement measuring device that the deflection of measuring point in the likeness in form simulated experiment is effectively measured to the rock stratum.
The utility model is achieved through the following technical solutions:
A kind of displacement measuring device that is applicable to the rock stratum mobile phase like simulated experiment, it is characterized in that, comprise light source, ccd video camera, three-dimensional transfer table, A/D converter, calculation control unit and display, on three-dimensional transfer table, be fixed with ccd video camera, around tested model, be provided with light source, the normal direction of described tested model is perpendicular to the axis of ccd video camera, and the output terminal of described ccd video camera is connected successively with A/D converter, calculation control unit and display.
The utlity model has following technique effect:
1, measurement mechanism of the present utility model belongs to the category of optical measurement, once takes the measuring point photo of the whole audience, realizes measuring the measurement of displacement by the cycle calculations of calculation control unit, has higher efficient.
2, this device only needs to take the photo under the different mining progress in experimentation, and measuring method is simple, and is convenient and swift.
Description of drawings
Fig. 1 is applicable to the synoptic diagram of rock stratum mobile phase like the displacement measuring device of simulated experiment for the utility model.
Among the figure: the 1-light source; The 2-CCD video camera; The three-dimensional transfer table of 3-; The tested model of 4-.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is applicable to the synoptic diagram of rock stratum mobile phase like the displacement measuring device of simulated experiment for the utility model, comprise light source, ccd video camera, three-dimensional transfer table, A/D converter, calculation control unit and display, on three-dimensional transfer table, be fixed with ccd video camera, around tested model, be provided with light source, the normal direction of described tested model is perpendicular to the axis of ccd video camera, and the output terminal of described ccd video camera is connected successively with A/D converter, calculation control unit and display.
To at first survey before the experiment, grasp real geological formations physical characteristics the true rock stratum that will study.Select the proportioning of suitable analog material (generally choosing common river sand, gypsum and three kinds of materials of lime) again according to the lithology of each rock stratum and mechanical characteristic.Then the analog material of different proportionings is completed at model experiment platform higher slice according to the actual conditions of prototype.And sprinkle a spot of mica powder at the rock stratum intersection and simulate the aspect effect, form the influence that plane of weakness is simulated tomography by artificial cutting rock stratum.Rule such as move in order to access the rock stratum that causes of simulation coal seam back production, the displacement measuring points sign has been arranged in the front of model, measuring point can with pin fixedly the mode of circular paper make.After model is made, dry naturally.
During measurement, adjust three-dimensional transfer table 3 and make the axis of the normal direction of tested model 4 perpendicular to ccd video camera 2.Brightness, the camera lens on the ccd video camera 2 and the aperture of adjustment lighting source 1 and the distance between ccd video camera 2 and the tested model are so that obtain high-quality test specimen surface image.High-quality image should make the measuring point sign imaging in the image clear, can clearly make a distinction with the background that indicates.Before simulation mining, measuring point image by ccd video camera picked-up body surface, the image of picked-up is through importing calculation control unit and display into after the analog to digital conversion of A/D converter, and exists and form image file in the calculation control unit, and this image is called reference picture.Each instrument and equipment is all not removable in experimentation, and along with the carrying out of simulation mining, record cast is at difference exploitation surface image constantly.The vision signal of picked-up is through importing calculation control unit and display into after the analog to digital conversion of A/D converter, becomes data file and is stored in the calculation control unit through analog to digital conversion.By measuring point analysis and the recognition system in the calculation control unit, but the measurement of measuring point deflection on the implementation model.This device is an identifying object with the measuring point of tested model surface, in experimentation, by calculation control unit the measuring point of model surface is followed the tracks of and is analyzed, thereby realize the displacement measurement of the measuring point of tested model surface.
