The side of end or receiving end, after probe body is inserted into through-hole 2-2, fixing seat assembly is installed on fixed block 2, which prevents from visiting
Head is moved along through-hole 2-2 one-dimensional square, is changed the distance between two probes, is influenced measurement accuracy.
In the prior art, vaseline coating thickness is not easy to control, largely effects on ultrasonic detection precision, all in order to be precisely controlled
The coating thickness of intellectual circle, in the horizontal coaming plate 3 of coaming plate 3(i.e. first and the second horizontal coaming plate 3) towards the side of through-hole 2-2 offer with it is recessed
Slot 3-2-1, groove 3-2-1 diameter are the circular groove 3-2-1 of 3mm, depth 10mm, and with a thickness of 3mm, groove 3-2-1 is interior to be applied coaming plate 3
Full medical ventolin is as couplant, so that probe can tightly be fitted on medical ventolin and emit, receive ultrasonic wave, and
Medical ventolin smearing thickness is 1mm, and ultrasonic transmission is relatively sharp accurate.
Pedestal 4 includes bottom plate and position-limit mechanism in the present invention, and fixed block 2 guarantees itself and receiving cavity by position-limit mechanism
Relative position, position-limit mechanism include limit plate and limited block 4-2, and limit plate and limited block 4-2 are limited in 2 side of fixed block to be fixed
Block 2, bottom plate are equipped with the spacing edge-cut 4-3 for plugging the notch 4-1 of coaming plate 3 and for plugging limit plate, and limit plate plugs
In in spacing edge-cut 4-3, limited block 4-2 is fixed on bottom plate, and there are two limited block 4-2 is set, it is remote to be respectively arranged at two fixed blocks 2
Side from receiving cavity, fixed block 2 and coaming plate 3 form the limit of first direction to fixed block 2 relatively, and each fixed block 2 is right
Two limit plates are answered, two limit plates are oppositely arranged the limit that second direction is formed to fixed block 2.
Vaseline is coated between coaming plate 3 and notch 4-1, fixed block 2 prevents from surpassing using damping materials such as high damping alloys
Sound wave propagates at receiving transducer 1-2 around cement/concrete；Longitudinal coaming plate 3-1 is by the characteristic impedances such as organic glass and cement
Material similar in slurries is made, and other materials can be used in transverse direction coaming plate 3-2；4 material of pedestal is that high damping alloy etc. damps material
Material prevents ultrasonic wave from propagating at receiving transducer 1-2 around cement.
A method of cement setting hardening rate is measured using above-mentioned apparatus, is included the following steps
Coaming plate 3 is installed on pedestal 4 by S01, surrounds accommodating chamber；
Fixed block 2 is placed in 3 two sides of coaming plate by S02, and transmitting probe 1-1 and receiving transducer 1-2 are respectively placed in the fixation of two sides
It is that probe end is contacted with coaming plate 3 in the through-hole 2-2 of block 2；
S03 is poured concrete mortar in accommodating chamber, opens ultrasonic wave detector 1, records the propagation time in real time, until cement
As hardenite；
When S04 is according to spacing and ultrasonic transmission between transmitting probe 1-1 and the coaming plate contacted with receiving transducer 1-2 3
Between obtain velocity of wave, draw velocity of wave-time graph and simultaneously calculate cement setting hardening rate.
Coaming plate 3 and hardening of cement body, cleaning plant are unloaded after the completion of detection.
The invention patent is specifically addressed below with reference to measured result shown in Fig. 2.
Test material is fast gravity die sulphate aluminium cement, and result curve is divided into 3 regions: meadow I, rapid growth area
II and approximate meadow III., it is apparent that I area's velocity of wave has almost no change, cement/concrete gradually condenses in this stage
But and the hardenite of not formed densification, so ultrasonic wave spread speed in slurry-semisolid is slower；And certain of arrival and IIth area
Velocity of wave rapid sharp increase when a critical point represents cement with very fast setting rate and develops into hardenite, this critical point
Corresponding abscissa value is final setting time (presetting period can traditionally measure)；III area's curve is gradually steady but so slightly increases
Long, this illustrates that cement still carries out slowly reaction after quick-hardening, and reaction speed is slower and slower, that is, represents this rank
Section cement forms intensity in slow hardening.
The above is only the preferred embodiment of the invention patent, it should be pointed out that: for the common skill of the art
For art personnel, under the premise of not departing from the invention patent principle, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the patent of the present invention.
The above is only a preferred embodiment of the present invention, and the present invention is not limited in the content of embodiment.For in this field
Technical staff for, can have various change and change within the scope of technical solution of the present invention, made any variation and
Change, within that scope of the present invention.
