Description
Technical field
The present invention relates to the controlled bitumen needle forcemeter of a kind of standard pin height of drop and penetration test method, the method is suitable at laboratory equipment simple and crude, without under the condition of special penetration test lighting installation or require to adopt under the point-device prerequisite of pen..
Background technology
The determination techniques of pitch pen. has formed certain method for normalizing, utilizes this method substantially can realize the Accurate Determining of pitch pen..Yet, the factor of analyzing influence pitch pen. test accuracy, one of key link is exactly to test contacting of Plays pin and bituminous sheaths, and this is also a difficult point.To this, in existing asphalt test rules, require standard pin just to contact with bituminous sheaths, be not only seamless but also do not exist needle point to enter the situation of asphalt membrane between standard pin and asphalt film, but during practical operation because the pitch color is pitchy or black, the standard pin needle point is very elongated, add to operate in water and carry out, it is unscientific only depending on naked eyes to see through water observation contact situation, reason is to estimate when whether needle point contacts with bituminous sheaths to tend to cause observational error, thereby occur that test point is too early or cross late and insert in pitch, causing the most at last test result bigger than normal or less than normal.At present, the equipment of measuring pitch pen. is divided into manual dial type penetrometer and the large class of automatic digital display formula bitumen needle forcemeter two substantially, the common ground of this two quasi-instrument is the situation that contacts that all adopts manual adjustments bituminous sheaths and standard pin, manual penetrometer particularly, owing to as automatic penetrometer, not adopting the equipment such as low-voltage lighting and magnifier, only with the observation of naked eyes, can't in water, accurately adjust the situation that contacts of bituminous sheaths and standard pin, make test have very large error, and when standard pin frayed when more serious as do not changed in time, to make experimental result less than normal, the accuracy of impact experiment.For addressing this problem, testing crew once proposed a lot of methods, as the blank sheet of paper method, changed Material Addition order etc., had larger error though accuracy increases, and the accuracy of measurement result is not ideal enough.
Summary of the invention

Pitch penetration test method of the present invention, specifically comprise the steps:
1, preliminary work
2, test procedure
1) in temperature control tank 13, water temperature reaches the position of mobile pitch sample 10 after the regulation test temperature, makes it to be positioned at standard pin 8 needle points belows;
2) hand-held pin connecting rod 3, press release-push 30, controller is received after this signal and is controlled electromagnet 21 energisings, the irony on the electromagnet magnetic head 21-1 absorption slide bar 25 on electromagnet 21 4, slide bar 25 drives stop tight screw 26 further to be compressed spring 24, and pin connecting rod 3 is stopped tight screw 26 and unclamps; Hand-held pin connecting rod 3 makes it slowly to descend, until release-push 30 while contacting with pitch sample 10, is pressed again in thick 9 bottom surfaces, controller is controlled electromagnet 21 outages after receiving this signal, and spring 24 is again given and stopped tight screw 26 thrusts, thereby pins pin connecting rod 3; Now the distance of standard pin 8 needle points and pitch specimen surface (being the cylinder bottom surface of thick 9) is 10mm;
3) adjust arrow 6 and make it to point to 20 times edges of groove, unclamp chuck 16, take off thick connecting rod;
4) rotation knob 7 slowly descends pin connecting rod 3, on the groove of arrow 6 direction needle connecting rods 3 along the time stop the rotation, the needle point of standard pin 8 10mm that accurately descended now, the needle point of standard pin 8 contacts with pitch test specimen 10 just;
5) press digital display meter 2 measuring staffs 1, make it to contact with pin connecting rod 3 tops, replacement digital display meter 2 readings are 0;
6) press on control panel and enter pin button 31, after controller is received this signal, the opening time relay is also controlled electromagnet 21 energisings, and pin connecting rod 3 is stopped tight screw 26 and unclamps; Pin connecting rod 3 and standard pin 8 freely fall into pitch sample 10, and after the time relay controls to the stipulated time, controller is controlled electromagnet outage, automatic locking pin connecting rod 3.
7) move lower measuring staff 1 and make it to contact up and down with pin connecting rod 3, now digital display meter 2 shows the penetration number that numerical value is pitch sample 10.
8) same pitch test specimen 4 replication is at least three times, and the distance between each measuring point and measuring point and pitch sample edge is no less than 10mm, before each mensuration, pitch sample 10 should be put into to thermostatted water.Each mensuration changed a clean standard pin or wipes clean with toluene or other solvents, then dries by clean cloth.When mensuration pen. is greater than 200 pitch sample 10, at least use three standard pins 9, could take out standard pin from the pitch sample until measured for three times.Get the mean value of three times as experimental result.
9) experiment finishes, and cuts off the electricity supply.
Annotate: the general assembly (TW) of pin connecting rod 3, knob 7 and standard pin 8 and counterweight counterweight is 100g, and during due to experiment, thick connecting rod takes off, and therefore do not comprise the quality of thick connecting rod.
The principle of work of penetrometer of the present invention:
During off working state, spring 24, in compressive state, tightly suppresses and stops tight screw 26, by the flank of thread that stops tight screw 26, fixes pin connecting rod 3; After pressing release-push 30, controller is controlled electromagnet 21 and is passed into electric current, slide bar 25 is further Compress Spring 24 under the absorption affinity of electromagnet 21, overcome spring force and move, stopping tight screw 26 and be opened, this hour hands connecting rod 3 can freely descend, after again pressing release-push 30, controller is controlled electromagnet 21 turn-off currents, and slide bar 25 returns to off working state under spring 24 effects, stops tight screw 26 and pins pin connecting rod 3; After rotation knob 7 is finely tuned, pitch test specimen 10 contacts just with standard pin 8, and by being lowered to pin button 31, controller is controlled the opening time relay, and makes electromagnet 21 pass into electric current; After the time relay is controlled and is reached the stipulated time (5s), controller is controlled electromagnet 21 interruptive currents, slide bar 25 returns to off working state under Compress Spring 24 effects, pin pin connecting rod 3, entering the pin operation is into the pin button by controller control time relay with the difference of releasing operation, after stipulated time, auto-breaking pins pin connecting rod 3, and non-manual outage.During test, can use as required adjusting button 19 to revise the stipulated time into pin, regulate button 19 the amended stipulated time is sent to controller.The stipulated time of using reset button will enter pin makes zero.
Press measuring staff 1 when standard pin 8 contacts with bituminous sheaths to pin connecting rod 3, now the probe reading on digital display meter 2, then make zero and tested, the displacement difference that to enter after pin 5s to press numerical value that measuring staff 1 now reads again be initial value, i.e. penetration number.
