Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of probe fine motion forced Aerated concrete blank hardness detecting instrument, including probe 1, cylinder 2, pressure transducer and controller, described cylinder 2 is provided with position limiting structure 3 near the bottom of cylinder barrel, space is left to form air chamber 4 between described position limiting structure 3 and the base of cylinder 2, the upper cover of piston rod of described cylinder 2 is equipped with back-moving spring 5, and one end of back-moving spring 5 is against on the piston 6 being installed in cylinder 2 piston rod bottom, and the other end is against the top of the cylinder barrel of cylinder 2；The cylinder barrel of described cylinder 2 is provided with the start bit sensor 7 for detecting described piston 6 position at position limiting structure 3, being respectively equipped with the air inlet pipeline 8 and gas exhaust piping 9 connected with air chamber 4 on the base of described cylinder 2, air inlet pipeline 8 and gas exhaust piping 9 are connected with air pump 10 and air bleeding valve 11 respectively；Described pressure transducer connects to detect the barometric information in air chamber 4 with air chamber 4；Described probe 1 is fixedly installed on the top end face of cylinder 2 piston rod, probe 1 preferably cylinder, and the best axial line with cylinder 2 piston rod of the axial line of probe 1 coincides；Described controller electrically connects with air bleeding valve 11, start bit sensor 7, pressure transducer and air pump 10 respectively.
nullAir pump 10 is utilized to inject gas in the air chamber 4 of cylinder 2 to produce the thrust promoting piston 6，And probe 1 is when contacting with billet surface，Base substrate hardness can be stretched out outside cylinder 2 with prevention piston rod on piston 6 in retroaction，Gas in air chamber 4 continues to gather，When the air pressure in air chamber 4 is more than billet surface hardness to the thrust moment of piston 6，Piston rod can promote probe 1 moment to burst inside entrance base substrate，Start bit sensor 7 will promptly send a signal of telecommunication when piston 6 has just left original position，Controller controls rapidly air pump 10 after receiving this signal of telecommunication and stops action，In piston 6 course of action，Barometric information omnidistance in air chamber 4 is transferred to controller through pressure transducer，The maximum pressure value that hardness current with base substrate to be detected matches is filtered out by controller，The maximum pressure value that controller is filtered out by technical staff is that standard contrasts with the Hardness Match value of qualified billet surface，I.e. can know whether the hardness of base substrate to be measured reaches standard.This detector reliability height, accuracy of detection and detection efficiency are high, are effective to ensure that the homogeneity of steam-pressing aero-concrete quality, can significantly improve the qualification rate of product, are conducive to improving the production efficiency of product, and then can obtain preferable economic well-being of workers and staff.
In order to be visually observed that testing result, also include the display 12 being connected with controller.
In order to make this detector be easy to carry, and can be convenient to operate, also including the support body 13 that be connected fixing with cylinder 2, controller, display 12, air pump 10 and air bleeding valve 11 are arranged in support body 13.
In order to make manufacturing process simple, described position limiting structure 3 is the spacing annulus being fixedly provided in cylinder 2 inner wall of cylinder or is at least two pieces of symmetrical limiting plates being fixedly provided in cylinder 2 inner wall of cylinder.
In order to make the small volume of this detector, described support body 13 is fixedly installed on the base of cylinder 2.
During use, probe 1 is conflicted in billet surface, the cylinder barrel of stabilized cylinder 2, it is made not occur position to move, press the start button of controller, air pump 10 is made to start working, compressed gas enters air chamber 4 through air inlet pipeline 8, pressure transducer detects the barometric information in air chamber 4 in real time, along with the gathering of air in air chamber 4, air pressure in air chamber 4 is gradually increased, when reaching a threshold value, gases at high pressure in air chamber 4 promote piston 6 to move out, and then the piston rod of cylinder 2 promotes probe 1 moment to burst inside entrance base substrate, when start bit sensor 7 detects that piston 6 leaves original position, a signal A can be sent to controller, controller controls air pump 10 after receiving this signal A and quits work, open air bleeding valve 11 to begin through gas exhaust piping 9 and be exhausted simultaneously.Air pressure in air chamber 4 is gradually lowered, then the elastic force by back-moving spring 5 makes the piston rod of cylinder 2 recover to original position, when start bit sensor 7 detects that piston 6 arrives original position, again sending out a signal B to controller, controller cuts out air bleeding valve 11 after receiving signal B.During whole, controller records and starts to start the barometric information change procedure in the air chamber 4 cutting out in this detection cycle to air bleeding valve 11 from air pump 10, filter out maximum gas pressure value, shown by display 12, so can be easy to match the hardness number of billet surface according to the atmospheric pressure value in air chamber 4, operator, can be that the numerical value that display 12 is demonstrated by standard is compared according to the Hardness Match value of qualified billet surface, thus reach quick, accurately obtain the purpose of billet surface hardness, so can guarantee that base substrate to be detected carries out cutting operation when hardness is suitable, it is effective to ensure that the homogeneity of steam-pressing aero-concrete quality, the qualification rate of product can be significantly improved, be conducive to improving the production efficiency of product.
