The speed sensor and an integrated circuit chip are utilized to measure and dispose the speed of the spring-impact hammer; the utility model solves the technical problems of that the measuring precision of the concrete resiliometer is not high, and the long-term stability is bad, thus largely reducing the manual work and improving the efficiency.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to instrument machinery, particularly concrete strength determinator, and concrete is a kind of high-precision electronic formula concrete bouncing back instrument.
Background technology:
In the prior art, concrete bouncing back instrument is a restoring force of utilizing spring to drive elastic hammer and be out of shape by the instantaneous elasticity that elastic stem attack concrete surface is produced, making elastic hammer drive pointer rebounds and indicates the distance of rebounding, and with rebound value, elastic hammer is inferred concrete compressive strength to the likening to one of relevant index of concrete crushing strength apart from it of elastic stem before that is to say the distance of rebounding and impacting.Because the elastic hammer snap-off-distance is very short, brings bigger error in the measurement, makes the concrete bouncing back instrument precision not high; The collection of measurement data, analysis, processing, judgement all need manually to finish, and have brought very big human factor and heavy manpower work, can not realize robotization; Elastic tension spring is after using certain number of times, stiffness coefficient will change, the rigidity of elastic tension spring is non-linear, attack face and pointer friction force and repeatedly use after site error or the like several factors cause present concrete bouncing back instrument long-time stability poor.
Summary of the invention:
The purpose of this utility model provides a kind of high-precision electronic formula concrete bouncing back instrument, and described this high-precision electronic formula concrete bouncing back instrument will solve in the prior art that measuring accuracy is not high, long-time stability difference and the big technical matters of hand labor amount.
The purpose of this utility model is achieved through the following technical solutions: this high-precision electronic formula concrete bouncing back instrument, by casing, centre pilot, elastic hammer, guide flange, tail-hood, hook, clamp nut, the zeroing screw, stage clip, elastic tension spring, the buffering stage clip, the extension spring seat, elastic stem and block constitute, block and elastic stem are arranged at casing one end, tail-hood is arranged at the casing other end, centre pilot is arranged at casing inside, centre pilot one end links to each other with elastic stem by the buffering stage clip, the centre pilot other end passes through guide flange, hook, the zeroing screw links to each other with tail-hood with clamp nut, be provided with hook pin and hook stage clip between guide flange and the hook, chassis sidewall is provided with button, it is characterized in that: at the enclosure wall middle part, be positioned at elastic stem one end and be provided with speed pickup, the signal output part of speed pickup links to each other with mould/number conversion module, mould/number conversion module one end is provided with data processing module, and data processing module one end is provided with display module.
Mould/number conversion module and data processing module are integrated circuit (IC) chip.
Principle of work of the present utility model is: during use, at first driving elastic hammer with hook moves along centre pilot, this moment, elastic tension spring was elongated, when moving to top, runs into hook the zeroing screw, elastic hammer is under the pulling force effect of elastic tension spring, strike on the elastic stem with certain speed, return with certain speed again, speed before and after the elastic hammer collision is all measured accurately by the nigh speed pickup of dress elastic stem, the rate signal that speed pickup is measured is sent to data processing module by mould/number conversion module after being converted into digital signal, data processing module carries out calculation process to rate signal, storage, obtain the single rebound value after the processing, the single concrete strength, average rebound value, and average concrete strength carry out the reasonable judgement of structure, reach a conclusion, all information show on display module.Thereby realized with rebound method to concrete strength fast, measure accurately, judge, the informationization of data and fast recording.So just reduce human factor, improved measuring accuracy, reduced heavy manpower work, improved work efficiency.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model utilizes speed pickup and integrated circuit (IC) chip that the speed of elastic hammer is measured and handled, and has solved that the concrete bouncing back instrument measuring accuracy is not high, the technical matters of long-time stability difference, reduces hand labor intensity significantly, raises the efficiency.
