Description

ASCON CLEANING DEVICE AS APPLYING ASPHALT CONCRETE

The present invention relates to an asphalt concrete cleaning device capable of cleaning the road surface in the pre-stage of repairing or paving an asphalt concrete (ASCON: ASphalt CONcrete) pavement. It relates to an asphalt concrete cleaning device at the time of asphalt concrete application that can improve the quality of asphalt concrete pavement.

In general, deterioration of asphalt road quality can be divided into external and internal factors. External factors include repeated expansion and contraction according to seasonal temperature changes, and non-uniformity of static and dynamic loads and stresses applied by vehicles. , cracks are occurring due to factors such as aging and subsidence of the ground.

In addition to the above-mentioned external reasons for quality deterioration, the reasons for the deterioration of the internal asphalt pavement can be largely attributed to two reasons. First, when installing asphalt concrete, the temperature drop or temperature unevenness may be the cause. In this case, it is important to maintain the standard temperature by keeping in mind the transportation of asphalt concrete and storage of asphalt concrete, and to maintain a constant temperature overall by mixing the asphalt concrete. In other words, when the temperature of asphalt concrete falls below the specified level or due to uneven temperature between asphalt concrete, the bonding force between crystals is lowered, and the life cycle of asphalt concrete pavement can be shortened.

Other than that, another reason for the internal quality deterioration is the mixing of foreign substances, or if there are foreign substances on the chart surface before asphalt concrete pavement, the quality of asphalt concrete pavement may deteriorate.

1 is a cross-sectional view showing an example of applying asphalt on the foreign material according to the prior art.

Referring to Figure 1, when the oil agent (2) is laid on the foreign material (1) in the case of this addition and the asphalt concrete (3) is installed thereon, the asphalt concrete (3) crack may occur due to the foreign material (1), Or, there is a fear that the level of asphalt concrete (3) pavement is lowered as much as the foreign material (1) is included. When the flatness is reduced due to foreign substances, there is a problem in that the risk of damage to the asphalt road is sharply increased as the flatness is lowered.

As such, when the asphalt concrete is stored or foreign substances are mixed into the asphalt concrete, cracks may occur.

The battery 300 supplies power to the vacuum cleaning means 400 . If a problem occurs in the battery 300 configured in the asphalt concrete cleaning device 100 , power may be supplied and used from the battery configured in the emulsion simultaneous installation finisher 10 . In this case, the power line connection line can be used by connecting the battery of the oil tank installation finisher 10 . That is, the battery 300 may use a battery that provides a direct current of the same voltage as that of the battery used in the oil brake installation finisher 10 .

The vacuum cleaning means 400 operates by receiving power from the battery 300 and sucks by-products on the road surface. A vacuum suction port 420 for sucking foreign substances, a first duct 430 that provides a path for transferring the suction force of a foreign substance sucked through the vacuum suction port 420 to the lower surface, the vacuum suction port 420 and the first duct ( The first foreign material collection box 440 configured to collect, store, and detach the foreign substances introduced through the 430, and the second duct 450 for sucking relatively light foreign substances that are not loaded in the first foreign material collection box 440 and are sucked in. ), a second foreign material collection box 460 configured to be detachable and store relatively light foreign substances transported by the ducts 430 and 450, and a vacuum driven by receiving power for sucking foreign substances from the battery 300 It is configured to include a filter 480 installed between the motor 470 and the second foreign matter collection box 460 and the vacuum motor 470 to prevent foreign substances from entering the vacuum motor.

On the other hand, each configuration of the vacuum cleaning means 400 will be described in detail.

The vacuum suction port 420 is a suction port for sucking foreign substances drawn in behind the rollers 500 and 510 . The vacuum suction port 420 sucks the foreign substances collected by the rollers 500 and 510 . The vacuum suction port 420 is formed on the bottom of the housing 200, is formed at the end of the first duct 430, and is formed as a hole in a rectangular shape corresponding to the horizontal direction of the road surface.

The first duct 430 is connected to the vacuum suction port 420 and provides a path for transferring the foreign material sucked through the vacuum suction port 420 . One side of the first duct 430 is connected to the vacuum suction port 420 of the rectangular shape, and the other side of the first duct 430 is connected to the first foreign material collection box 440 . The first duct 430 sucks the foreign material flowing in from the rectangular vacuum suction port 420 and transfers it to the first foreign material collection box 440 connected to the other side. One side of the first duct 430 is gradually transformed into a trapezoid or triangular shape from a rectangle toward the other side, and the other side is configured in a cylindrical shape and is connected to the lower surface of the vacuum cleaning means 400 to collect the transported foreign substances. Collect in the box (440).

The first foreign material collecting box 440 collects foreign materials introduced through the vacuum suction port 420 and the first duct 430 . At this time, the first foreign material collecting box 440 is configured in the lower portion of the first duct 430 to collect relatively heavy foreign matter primarily. The first foreign material collection box 440 is detachably configured in the form of a drawer so that it can be pulled out of the housing 200 and inserted again.

The vacuum motor 470 is driven by receiving power for sucking foreign substances from the battery 300 to provide suction power. The vacuum motor 470 is configured with the second foreign material collecting box 460 and the filter 480 interposed therebetween. The vacuum motor 470 creates a vacuum state according to the rapid flow of air in the first duct 430 and the second duct 450 by using suction and discharge of air in a closed area to provide suction force. External foreign substances are sucked in using the path and are collected in the first foreign material collecting box 440 and the second foreign material collecting box 460 , respectively. The outlet 472 is configured in the form of a through hole in the housing 300 of the portion accommodating the vacuum motor, and is introduced through the ducts 430 and 450 by the air flow made by the vacuum motor 470 to filter 480. The air passing through is discharged to the outside of the asphalt concrete cleaning device 100 through the outlet 472.

On the other hand, the foreign substances that have passed through the second duct 450 are collected in the second foreign matter collection box 460 . The second foreign material collection box 460 is also detachably configured in the form of a drawer so that it can be inserted again after being detached from the housing 200 . Foreign substances larger than the air gap of the filter 480 are blocked by the filter 480 and do not flow into the vacuum motor 470, but foreign substances or dust smaller than the gap of the filter 480 can pass through the filter 480 and be discharged to the outside. have. At this time, the size of the discharged foreign material can be adjusted according to the gap between the filter. The filter 480 may be a HEPA filter, a non-woven filter, or a filter made of a wire mesh material.

The filter 480 is configured to separate the end of the second duct 460 from the vacuum motor 420 , and may use a woven nonwoven fabric, or may be made of a HEPA filter or iron mesh. At this time, since the size and shape of foreign substances generated on the road surface may impact the filter, a steel mesh may be used as the filter 480 in consideration of durability.

The rollers 500 and 510 are configured on the front surface of the vacuum cleaning means 400 and rotate to attract foreign substances to the lower surface of the vacuum cleaning means 400 . The rollers 500 and 510 configured on both sides are composed of a left roller 500 and a right roller 510, are configured on both sides close to the front, are stored by folding to the side, and when used, can be used by unfolding it in the forward direction. . The rollers 500 and 510 are configured to extend an angle in the form of wings forward on both front sides of the vacuum cleaning means 400 from a folded state on the side. That is, the rollers 500 and 510 are used in an expanded state according to the width of the road surface paving the asphalt concrete. Each of the rollers 500 and 510 is operated by a motor 520 operated according to the power received from the battery 300 to transfer foreign substances on the side to the inside where the vacuum suction port 420 is located. Each of the rollers 500 and 510 rotates in the inward direction of the road surface with respect to the floor surface, and collects foreign substances in the front to the center of the road surface. A motor 520 provides power to the two rollers 500 and 510 . The two rollers 500 and 510 are rotated toward the inner surface of the road surface by receiving power from the motor 520 . On the other hand, arrows from the left roller 500 and the right roller 510 to the vacuum cleaning means 400 in FIG. 2 illustrate that the foreign materials on the road surface are collected and transferred to the vacuum cleaning means 400 direction.

The moving means 600 includes a plurality of wheels 610 and a shaft (not shown) supporting the wheels 610 . When the wheel 610 rotates by the power of the oil brake installation finisher 10 , the shaft also rotates while being supported by the inner surface of the asphalt concrete cleaning device 100 . The wheel 610 and the shaft are configured in the same number. The shaft is connected through the center of the wheel 610 while being supported on the main body of the asphalt concrete cleaning apparatus 100 so that the wheel 610 and the wheel 610 can rotate. Each wheel 610 and the shaft are each configured to be rotatable in pairs, and are stably arranged in a triangular or quadrangular shape in three or four pairs on the lower surface of the housing 200 . Each wheel 610 is fixed through the center of an independent shaft, and each shaft is supported on the body of the asphalt concrete cleaning apparatus 100. Accordingly, even if the number of rotations of each wheel 610 is different, each wheel may move individually. In the embodiment of the present invention, each of the four wheels 610 and the shaft is supported by the illustrated asphalt concrete cleaning device 100 to move.

On the other hand, after the road surface is cleaned by the asphalt concrete cleaning device 100 , the oil agent is installed almost simultaneously by the oil agent simultaneous installation finisher 10 .
