Description
Technical field
The utility model relates to compression rebound modulu test unit technical field, is specially a kind of novel anti and pushes back bullet modulus test anchor clamps.
Background technology
Compression rebound modulu is the key parameter of pavement structure stress-strain analysis, and it is an important indicator in the pavement structure design, and whether the compression rebound modulu value is reasonable, is related to serviceable life and the construction costs on road surface; If the compression rebound modulu value is excessive, road surface thickness is inevitable thinner, can not satisfy road serviceable life; If the compression rebound modulu value is too small, road surface thickness increases will cause that unnecessary cost drops into.
At present the compression rebound modulu measuring method of using in the standard is to record with microcomputer controlled pressure machine and two clock gauges, and this measuring method not only wastes time and energy, and can to cause test findings to depart from very big because of problems such as clock gauge installations.How to prevent that because problems such as clock gauge installation cause the test findings error big the precision that improves compression rebound modulu measurement test has become problem demanding prompt solution.
The utility model content
The technical matters that the utility model solves is to provide a kind of novel anti to push back and plays the modulus test anchor clamps, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
Novel anti pushes back and plays the modulus test anchor clamps, comprises seaming chuck, push-down head, goes up anchor clamps, lower clamp, pressure transducer, hand held console, self-actuated controller; Wherein, last anchor clamps are installed on the seaming chuck, and lower clamp is installed on the push-down head; Pressure transducer is installed on the pressing machine, and seaming chuck is fixed in the pressing machine bottom, and push-down head is fixed in hand held console, and pressure transducer is connected with self-actuated controller.
In the utility model, last anchor clamps are T type structure, and have through hole at the vertical top end of T type structure.
In the utility model, lower clamp comprises punch and die.
In the utility model, by the loading of the adjustable whole pressing machine of hand held console, realize manual automatic integratedization, handled easily uses.
In the utility model, before the use, adjust the pressure transducer that is installed on the pressing machine earlier, will go up anchor clamps and lower clamp simultaneously and be fixed in seaming chuck and push-down head by nut, and test specimen will be placed on the punch and die of lower clamp; The automatic levelling function of anchor clamps and lower clamp contacts function with centering in the debugging; Earlier gently press test specimen with less power then, at this moment, lower clamp plays the leveling effect, and the ess-strain measured value of observing in the self-actuated controller is consistent with the ess-strain displayed value on the pressing machine, guarantees that data are accurate; Then finish testing automatically according to the compression rebound modulu program of working out in the self-actuated controller; Namely realize the detection modulus of resilience index of high-accuracy high-efficiency rate robotization; Improve the true and reliable property that detects numerical value.
Beneficial effect: the utility model is realized the detection modulus of resilience index of high-accuracy high-efficiency rate robotization by pressing machine and self-actuated controller; Seaming chuck not only can with the pressing machine seamless link, and can under less pressure, realize automatic leveling, avoid occurring the bias voltage phenomenon, test specimen is placed on lower clamp punch and the die, effectively improves the true and reliable property that detects numerical value; Reduce the manpower and materials expenditure, and anchor clamps has using value widely.
