Abstract
The utility model discloses a kind of blasting vibration tester field calibration device, comprise base (1), on base (1), be vertically fixed with vertical rod (2), in vertical rod (2), be fixed with one group of downward-sloping guide runner (3), described guide runner (3) is provided with stop pin (5) near vertical rod (2) end, and steel ball (4) is positioned at guide runner (3) and is stopped pin (5) and blocks.The utility model can make to glide in the guide runner of steel ball differing heights from being arranged on vertical rod, after steel ball free falling bodies, contact and produce the standard vibration source of different-energy size with ground, therefore, when calibration blasting vibration tester, whether whether the size that only needs to observe vibration signal is consistent with the last time, can judge whether blasting vibration tester can normally work, install and put in place.
Description
Technical field
The utility model relates to a kind of blasting vibration tester field calibration device, belongs to blasting vibration technical field of measurement and test.
Background technology
At present, when blasting vibration tester carries out on-the-spot test, generally after blasting vibration tester installs, test probe is fixed on to test point position, then produce vibration source by the mode such as stamp one's foot, see whether blasting vibration tester can monitor vibration signal, thereby judge whether blasting vibration tester can normally work.Conventionally on-the-spot test environment is more severe, interference vibration source is more, therefore produces the energy of vibration source by the mode such as stamp one's foot not of uniform size, and the signal fluctuation that probe of tester collects is larger, be difficult to tester to be calibrated, affect the accuracy of tester test result.
Utility model content
The purpose of this utility model is, provides a kind of simple in structure, blasting vibration tester field calibration device that can produce standard vibration source, to overcome prior art deficiency.
The technical solution of the utility model: a kind of blasting vibration tester field calibration device, comprise base, on base, be vertically fixed with vertical rod, in vertical rod, be fixed with one group of downward-sloping guide runner, described guide runner is provided with stop pin near vertical rod end, and steel ball is positioned at guide runner and is stopped pin and blocks.
The cross sectional shape of described guide runner is semicircle or V-arrangement, and the inclined angle alpha of guide runner and surface level is 5 °.
Described stop pin is T shape stop pin.
Owing to adopting technique scheme, the utility model can make to glide in the guide runner of steel ball differing heights from being arranged on vertical rod, after steel ball free falling bodies, contact and produce the standard vibration source of different-energy size with ground, therefore, when calibration blasting vibration tester, only need the size of observation vibration signal whether consistent with the last time, can judge whether blasting vibration tester can normally work, install and whether put in place, avoid present stage to adopt artificial random excitation vibration source to judge the erroneous judgement risk whether vibration measurement instrument can normally work.The utility model is simple in structure firm, easy to operate, reliable for effect, practical.

Embodiment
In order to make the utility model object, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of blasting vibration tester field calibration device of the present utility model, comprise 300 × 300 square base 1, on base 1, be vertically fixed with a cylindrical vertical rod 2, in vertical rod 2, be fixed with three downward-sloping guide runners 3, between described guide runner 3, be spaced apart 0.5m, referring to Fig. 1 and Fig. 3, be provided with T shape stop pin 5 at guide runner 3 near vertical rod 2 ends, steel ball 4 is positioned at guide runner 3 and is blocked by T shape stop pin 5; Referring to Fig. 4, the cross sectional shape of described guide runner 3 is semicircle, and guide runner 3 is 5 ° with the inclined angle alpha of surface level.
When test, first the probe of blasting vibration tester is arranged on to test position, then open blasting vibration tester, now the T shape stop pin 5 on guide runner 3 is extracted out, steel ball 4 is glided along guide runner 3, steel ball 4 is done the movement of falling object after leaving guide runner 3, last steel ball 4 lands the standard vibration source that produces, therefore, if blasting vibration tester normally just can collect vibration signal, and the steel ball 4 of guide runner 3 landings by three differing heights produces three kinds of standard signals, according to thereby the data analysis of three kinds of signals being judged to whether blasting vibration tester normally works.If waveform is abnormal, should check whether the probe installation of blasting vibration tester is reasonable, carry out after improve at scene recalibrating.
