Description

A PIVOTING ANGLE MEASURING EQUIPMENT OF GYRATORY COMPACTOR

The present invention relates to an apparatus for measuring the turning angle of a turning compactor, and more particularly, when producing an asphalt specimen, provides a production environment close to the pressurized environment by the compaction roller during actual asphalt pouring, and is used for repetitive specimen production It relates to a turning angle measuring device of a turning compactor capable of securing a more accurate result by securing the turning angle of a molding part to be used through direct contact measurement in a conventional indirect method.

The physical properties of the mixture for road pavement (asphalt and cement-concrete mixture, subgrade, cement-soil mixture, asphalt-cement mixture, subgrade) indicate the overall quality characteristics of the mixture and have a close correlation with the pavement compatibility. For this reason, it is very important to accurately measure the physical properties of materials. When measuring the properties of materials, the precision, reliability, and reproducibility of the measured data are key considerations in the selection of test equipment and test specimens.

Nevertheless, the measurement results of road pavement materials so far have always shown negligible errors and have been taken for granted.

In particular, in the case of a test specimen for a test on a mixture for road pavement, it is possible to secure the most desirable results to collect from an actual road paved area, but in reality, the test specimen has a limitation in that it is produced by a specimen production device, and furthermore, now In the case of the specimen manufacturing apparatus known so far, there is a problem in that the error becomes larger by using the specimen produced regardless of the environment at the time of actual asphalt pouring.

That is, in the case of the conventional asphalt specimen manufacturing apparatus, the mixture for road pavement is accommodated in the molding unit and is manufactured by hitting and pressing using a certain striking mechanism. There is a difference in that it is cured after turning using a compaction roller on it.

In order to solve the above problems, the applicant of the present invention registered as a technical configuration related to a turning angle measuring device of a turning compactor that can produce a specimen by giving an environment during actual asphalt pouring [Registration Patent No. 10-1900346 ( 2018.09.13.registration)] have been received.

However, the above-mentioned registered patent also has a problem, because the rotation angle of the molding part is measured by detecting the external movement of the molding part where the specimen is manufactured using a displacement measuring magnetic sensor (LVDT, Linear Variable Differential Transformer). There is a problem in that the measured turning angle is not accurate due to the physical error of the surrounding parts. The measurement error of the turning angle of the molding part leads to a problem of lowering the reliability of the specimen manufactured by the molding part.

The probe 525 is provided so that its tip is in contact with the inner circumferential surface of the molding part 100 , and its tip is a straight line with respect to the gauge body 520 by an external force transmitted through interference with the pivoting molding part 100 . can be moved The distance (distance on the X-axis) moving in the straight direction of the tip of the probe 525 is a vertically rising distance (distance on the Y-axis) from the lower portion of the gauging case 510 to the tip (measurement point) of the probe 525 . When is fixed as a constant, it is measured as a variable distance according to the turning motion of the molding part 100 , and such a measurement value of the probe 525 may be calculated as the current turning angle of the molding part 100 .

In more detail, the probe 525 penetrates through the probe exposure hole 511 cut to communicate with the inner space of the gauging case 510 as shown in Figs. A predetermined length may be exposed to the outside of the temporary gauging case 510 .

Accordingly, the tip (ie, the measurement point) of the probe 525 exposed to the outside of the gauge body 510 is provided to be movable by a predetermined distance along the X-axis, and is relative from the tip (ie, the measurement point) of the probe 525 .

It may further include a fixing jig 540 for fixing in the direction.

That is, the gauging case 510 may have a predetermined internal space in which the gauge body 520 and the fixing jig 540 can be installed therein.

A gauge body 520 is disposed in a horizontal direction on a relatively upper side of the inner space of the gauging case 510 , and the probe 525 extends in the horizontal direction of the gauge body 520 to form one side of the gauging case 510 .

On the other hand, an embodiment of the turning angle measuring device 500 of the turning compactor according to the present invention is provided on the outer peripheral surface of the gauging case 510, as shown in FIGS. It may further include an angle display panel 560 that visually displays the turning angle of the molding part 100 measured by the .

The angle display panel 560 calculates the turning angle of the molding part 100 measured by the probe 525 in real time and displays it in numbers or characters, so that the measurer can directly check in real time with his or her eyes. .

In more detail, the molding part 100 is provided with a cutout 105 in which a part of the outer circumferential surface is cut out so that the inside can be observed from the outside, and the angle display panel 560 is placed in the portion provided with the cutout 105 . It is set to be positioned so that the measurer can visually confirm it from the outside even through the front door 19 provided in the front part of the main body case 10 among an example of the turning compactor 1 .

A process of measuring the turning angle of the molding part using an embodiment of the turning angle measuring device of the turning compactor according to the present invention configured as described above will be briefly described with reference to FIG. 8 as follows.

Among the configurations of an example (1) of the turning compactor, the molding part 100 is rotated by the left and right vibration guide 120 and the forward and backward vibration guide 130 as shown in FIGS. 8 (a) and (b). However, it is provided to rotate at a predetermined angle in one direction and the other direction with respect to the axis of movement of the pressure shaft 220 that is vertically moved.

A measurer who wants to measure the turning angle of the molding part 100 uses the turning angle measuring device 1 of the turning compactor according to an embodiment of the present invention as shown in FIG. ) is inserted through the open upper side, and the pressing plate 230 for pressing the specimen of the molding unit 100 is hollowly inserted through the open lower side of the molding unit 100, and then the turning pressing unit is driven.

Then, as shown in (b) of FIG. 8 , the tip of the probe 525 of the gauge body 520 exposed to the outside by a predetermined length through the probe exposure hole 511 of the gauging case 510 is a molding part. While in contact with the inner circumferential surface of 100 , it is interfered with the inner circumferential surface of the turning molding part 100 and is linearly moved a predetermined distance.

Here, the tip (ie, the measuring point) of the probe 525 is exposed at a position spaced apart by X from the outer end of the first gauging case 510, It is linearly moved by a distance minus a and moved to the inside of the gauging case 510 , and it is possible to accurately measure the current turning angle of the molding unit 100 through a linear moving distance equal to a.

Above, an embodiment of the turning angle measuring device of the turning compactor according to the present invention has been described in detail with reference to the accompanying drawings. However, the embodiment of the present invention is not necessarily limited by the above-described embodiment, and it is natural that various modifications and implementations within an equivalent range are possible by those of ordinary skill in the art to which the present invention pertains. will be. Therefore, the true scope of the present invention should be defined by the claims to be described later.
