Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of innovative surrounding strain gauge means of the present embodiment, including sensor and tinsel 9, sensor includes stator 1 and the foil gauge being arranged on by the way of bonding on stator 1, stator 1 is made for steel material, stator 1 is fixedly installed on base 2, base 2 uses aluminum material to make, base 2 is through square body, stator 1 right-hand member is provided with bolt hole 11, it is connected fixing to stator 1 and base 2 top right side by bolt, so that sensor does not shakes during measuring；Curved shape bottom base 2, can match with column rock sample, and during experiment, column rock sample is embedded in the arc bayonet socket of base 2, it is ensured that whole device does not slides during measuring, it is to avoid affect certainty of measurement.
The present embodiment is provided with winding bore 3 at stator 1 left end, is provided with the most through and corresponding with winding bore 3 first and passes hole 4 on the left of base 2, and base 2 left bottom is provided with and the first left limit hole 5 connected through hole 4；Base 2 bottom right side is provided with the right limit hole 6 that left limit hole 5 is arranged symmetrically with, base 2 bottom right side is provided with second extending from bottom to top and connect with right limit hole 6 through hole 7, be provided with on the right side of base 2 the most through and connect through hole 7 with second the 3rd pass hole 8.
Between bolt end and the stator 1 of the present embodiment, there is distance, between stator 1 left end and base 2 left side top, also there is certain distance, contribute to being sintered to fix of tinsel 9.
The present embodiment is provided with observation port 12 in base 2 lower right side.
When rock sample 10 is tested, first tinsel 9 one end is sintered in the winding bore 3 of stator 1, this side end of flicking stator, is to apply certain prestressing force to tinsel 9, is allowed to keep tight state, it is ensured that the sensitivity during measurement；Then another tinsel 9 sequentially passes through first through hole 4 and left limit hole 5, is wound around along stone sample 10 surface, sequentially passes through right limit hole 6, second again through hole 7 and the 3rd through hole 8, and tinsel 9 other end is sintered on bolt.Complete after tinsel 9 is sintered to fix, it is also possible to whether observe tinsel 9 already at tension by reserved observation port 12.
The transmittance process of the present embodiment strain is: when rock sample 10 occurs hoop strain, tinsel 9 is owing to being close to rock sample 10 surface, also can be forced to elongation and produce tension, tension make a concerted effort by the winding bore 3 being sintered in sensor make stator 1 produce bending, the upper surface posting foil gauge is correspondingly made to produce strain, such that it is able to the moment is monitored by foil gauge, and feedback data is to receiver end.Thus, the rock sample 10 hoop strain monitoring in loading complete process can just be realized.
The hoop strain measurement apparatus of the present embodiment, eliminate test hoop strain every time and will paste the step of foil gauge along stone sample outer surface, by being wrapped in the tinsel along stone sample appearance, drive the deformation of stator, thus by the hoop strain Real-time Feedback along stone sample to receiving terminal, by simple conversion, concrete data and the change curve of rock sample hoop strain in loading procedure can be directly obtained.
The hoop strain measurement apparatus of the present embodiment, reasonable in design, simple in construction, easy to use, highly sensitive, it is adaptable to laboratory experiment is measured in the hoop strain of rock sample.
The above, be only preferred embodiment of the present utility model, and structure of the present utility model is not done any pro forma restriction.Every any simple modification, equivalent variations and modification made above example according to technical spirit of the present utility model, all still falls within the range of the technical solution of the utility model.
