[0003] However, when the current size measurement device conducts visual inspection on concrete specimens, it cannot effectively correct and limit the position of the concrete, making it difficult to achieve effective alignment and focusing of the scanner.

[0054] The working principle and usage process of the present invention: When the concrete specimen size measuring device is actually used, first open the housing 100, connect an external inflation device to the air valve 314, inject air into the inner part of the central cylinder 309 through the air valve 314, force the vertical plug 312 to abut against the bottom end of the central cylinder 309 under the action of air pressure and its own gravity, and block the through hole 313. By adjusting the air pressure at the top of the vertical plug 312, the air pressure required for the vertical plug 312 to rise can be limited. And the air pressure that drives the vertical plug 312 to rise will be synchronously applied to the concrete specimen for the limitation of the concrete specimen. That is, by adjusting the air pressure at the top of the vertical plug 312, the limiting pressure received by the concrete specimen during the measurement process can be limited. Hereinafter, the air pressure required for the vertical plug 312 to rise is uniformly referred to as the limiting air pressure;

[0055] During the measurement process of concrete specimens of the same batch and specification, the above adjustment work only needs to be carried out before the first measurement. During the measurement process of concrete specimens, start the air pump 306. The air pump 306 will extract the air inside the material box 302, send the air flow into the protection cylinder 301 through the conveying pipe 307, force the turbine 305 to rotate under the impact of the air flow, and then the air flow enters the connecting seat 310 through the inner pipe 311. When the air flow pressure is lower than the limiting air pressure, it is not enough to overcome the gravity of the vertical plug 312 itself and the air pressure at the top of the vertical plug 312 to make the vertical plug 312 rise. At this time, the air flow will preferentially flow into the air pipe 222;

[0056] Subsequently, the air flow will enter the guide base 221 through the trachea 222 and synchronously enter each pushing cylinder 204 under the conveyance of the guide base 221, forcing the plug blocks 205 in each pushing cylinder 204 to slide correspondingly under the action of air pressure, so that the pistons 207 inside each longitudinal cavity 202 and transverse cavity 203 slide correspondingly under the drive of the push rods 206. Then, under the push of the pistons 207, a part of the hydraulic fluid inside each transverse cavity 203 will be pressed into the corresponding transverse box 2092 through each conduit 211, and a part will be pressed into the chamber 212 inside the corresponding transverse cavity box 2082 through the elbow pipe 210. And the hydraulic fluid inside each longitudinal cavity 202 will, under the push of the pistons 207, a part will be pressed into the corresponding longitudinal box 2091 through each conduit 211, and a part will be pressed into the chamber 212 inside the corresponding longitudinal cavity box 2081 through the elbow pipe 210;

[0057] Then, the guide plates 213 inside each double - cavity box 208 and side box 209 will slide the corresponding clamping plates 215 under the drive of the support rods 214 under the action of the hydraulic fluid. Since the limiting and correcting processes of the four concrete specimens on the top of the workbench 201 are exactly the same, for the convenience of description, the adjustment process of one of the concrete specimens is taken as an example for elaboration;

[0058] Under the hydraulic action inside the longitudinal cavity box 2081 and longitudinal box 2091, the clamping plates 215 on the longitudinal cavity box 2081 and longitudinal box 2091 will displace towards each other longitudinally and push the concrete specimen to displace longitudinally when contacting the concrete specimen. Under the hydraulic action inside the transverse cavity box 2082 and transverse box 2092, the clamping plates 215 on the transverse cavity box 2082 and transverse box 2092 will displace towards each other transversely and push the concrete specimen to displace transversely when contacting the concrete specimen. The existence of the balls 2011 can greatly reduce the frictional force required to be overcome during the displacement of the concrete specimen, enabling the concrete specimen to displace more stably following the push of the clamping plate 215. Finally, the clamping plates 215 on the four sides of the concrete specimen contact the concrete specimen simultaneously, and at this time, the center of the concrete specimen will be directly above the core plate 105, achieving the position correction of the concrete specimen;

[0059] During the above process, as the clamping plate 215 displaces, a corresponding amount of hydraulic fluid will be respectively pressed from the corresponding longitudinal cavity 202 and transverse cavity 203 into the corresponding longitudinal cavity box 2081, transverse cavity box 2082, longitudinal box 2091 and transverse box 2092. Correspondingly, the piston 207 will displace a corresponding distance. Under the linkage of the connecting rod 217, the plug plate 218 inside the isolation cylinder 219 in the corresponding longitudinal cavity 202 and transverse cavity 203 will also slide a corresponding distance. Furthermore, the plug plate 218 will squeeze the air inside the isolation cylinder 219, causing the air pressure inside the isolation cylinder 219 to change correspondingly, that is, the displacement distance of the clamping plate 215 corresponds one - to - one with the displacement distance of the piston 207 and the air pressure value inside the isolation cylinder 219;

[0060] During the measurement of concrete specimens, when the clamping plates 215 on the four sides of the concrete specimen contact the concrete specimen simultaneously, the pressure sensor 216 will feedback a signal to the external detection terminal, indicating that the calibration work on the concrete specimen is completed at this time. Meanwhile, the air pressure sensor 220 will feedback the air pressure in the corresponding isolation cylinder 219 to the external detection terminal. By converting and processing the air pressure data by the external terminal, the distances that the corresponding clamping plates 215 move horizontally and vertically can be obtained at this time. Subtracting the displacement distance of the clamping plates 215 from the initial distance between the corresponding clamping plates 215 can obtain the length and width dimensions of the concrete specimen;

[0061] In the above process, under the connection of the guide seat 221, the air pressure applied to each plug 205 will be kept consistent, and the corresponding clamping plates 215 corresponding to each concrete specimen will act synchronously. When some of the clamping plates 215 contact the concrete specimen first, they are restricted by the concrete specimen, and the air pressure will preferentially drive the displacement of the clamping plates 215 that have not contacted the concrete specimen, that is, it will preferentially drive the displacement of the clamping plates 215 with a smaller required driving pressure. In this way, automatic and repeated adjustment is carried out, and finally the clamping plates 215 on the four sides of each concrete specimen will fix the concrete specimen directly above the core plate 105 with the same force, and the synchronous measurement of each concrete specimen is realized through the above process. This measurement is an auxiliary pre-measurement;

[0062] After completing the position calibration and auxiliary pre-measurement of the concrete specimen, the external detection terminal will drive the scanner 102 to displace through the focusing mechanism 101. With the calibration effect of the position of the core plate 105, the scanner 102 can be accurately aligned with the concrete specimen, and the scanner 102 is focused up and down. The lens and sensor carried by the scanner 102 will accurately scan the concrete specimen and feedback the scan data to the external detection terminal to obtain the side length, angle and flatness data of the concrete specimen. The external detection terminal compares this data with the pre-measurement data. According to actual requirements, only when the difference between the measurement data of the scanner 102 and the pre-measurement data is within the standard range can it be ensured that the alignment work between the concrete specimen and the scanner 102 is accurate enough, the measurement data of the scanner 102 is valid, and the detection of concrete specimens with different sizes, different types and different specifications can be realized;

[0063] Meanwhile, during the detection of the concrete specimen, the turbine 305 will drive the rotating disk 104 to rotate through the hollow shaft 304, so that each concrete specimen rotates synchronously under the drive of the workbench 201, enabling the scanner 102 to scan the concrete specimen more comprehensively. And the air pressure driving the turbine 305 rises gradually, making the starting process of the rotation of the workbench 201 smoother;

[0064] When the air flow pressure is not lower than the limit air pressure, it is sufficient to overcome the gravity of the vertical plug 312 itself and the air pressure at the top of the vertical plug 312 to cause the vertical plug 312 to rise. At this time, the vertical plug 312 will rise under the action of the air pressure and finally no longer block the through hole 313. The air flow will enter the octagonal box 308 through the through hole 313, keep the air pressure inside the connecting seat 310 at the limit air pressure, and limit each concrete specimen at this air pressure. Subsequently, the air flow will enter each corner box 315 and air box 316 under the conduction of the through pipe 317, and finally spray onto the concrete specimens through each filter plate 318 to clean the surface of the concrete specimens;

[0065] As the air inside the material box 302 is pumped out by the air pump 306, a negative pressure will be formed inside the material box 302, forcing the air inside the side groove 321 to enter the protection cylinder 301 under the action of the negative pressure and enter the material box 302 from the protection cylinder 301, thus forming a circulating air flow and a negative pressure at the mesh plate 322. Coupled with the blowing action of the air flow at each filter plate 318, the residues and impurities falling from the concrete specimens are forced to fall into the side groove 321 along with the air flow and fall into the drawer 319 along the protection cylinder 301 under the limitation of the feeding hopper 323 and the cover plate 324 for centralized collection.
