Abstract

The invention relates to a measurement technique and serves to measure displacements and deformations of an object, such as rock samples, under laboratory and mine conditions. The inventive principle of the invention is the extension of functionality by registering relative deformations of adjacent points of an object. The movement and deformation of the object 7 due to non-synchronous rotation of the cams 11, the pointer 10 of the movements of the first sensor 2 will register the displacement of the point 6 of the object 7 relative to the housing 1 of the device, and the indicators 10 of the sensors 3-5 will indicate the relative displacements of the adjacent points of the object. This achieves the desired effect - the registration of relative mixing of adjacent points of the object, which allows you to quickly, 1 conclusion about the nature of the deformation of the sample. 1 hp f-ly, 1 ill.

Description

And: i) shaving refers to measuring equipment, namely, devices for measuring deformations of objects, for example, about: iuoH, during mechanical testing.

The purpose of the invention is the allocation of functionality by registering the relative deformations of adjacent points of the object.

The drawing shows the device section.

The device includes a housing 1, sensors 2 5 located therein in terms of the number of points 6 observational observations on object 7. Do not include each rail 8 for communication with object 7, 1 trunk 9 connected to rail 8, and indicate; The slats of the rail 8. The device also contains sets of cusps 11, the number of which is equal to the number of sensors 2 5. Each of the cams is fixed, aeii on the pinion axis 9. Each pointer is filled in the form of a converter, 1 linear displacements, in this case rheostat , with DEPMY moving each other | and by ulamegts 12 and 13. When the fatigable is the first mobile element. 12 of the first uk. Athele 10 is connected to housing 1, and the Eiropoii (13) is kinematically connected with the first and the first mix sensors. () one hundred, the pointers 10 are placed between adjacent kuchs, 1 1 1 displacement sensors, so that the first movable element of each pointer is connected to one cam 11, and the second movable:) element is connected to another cam II, adjacent1) to the first. Both movable sigmets 12 and 13 of each pointer K) no; i are the firearm each other.

The device works as follows.

With the same movement of all observation points 6 on object 7, the magnitude of this movement is registered only by the displacement sensor 2, one movable element 12 of the indicator 10 of which is fixed to the housing 1, and element 13 is kinematically connected to the cam 11 through the center 9 of the rail .

In case of unequal displacement of all

The points of observation 6 on object 7 (due to the turn or bending of the object) distances between adjacent cams will be different due to their d) synchro rotate. The pointers 10 displacement sensors 3-5 detect the relative displacements.

The registration of the relative smtendia of 2 s. Adjacent points of the object allows us to quickly draw a conclusion about the nature of the deformations of image 1.1a.
