Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction equipment, in particular to a road rolling device and a rolling system. Background Art
[0002] Rutting refers to the sinking, depression or wheel marks formed on the road surface due to frequent vehicle traffic, which affects driving comfort.
[0003] According to research and analysis, compaction effect is very important for preventing rutting diseases. Among them, compaction effect refers to the result obtained after compacting soil or asphalt concrete using compaction equipment (such as rollers, etc.) in road construction. The compaction effect mainly focuses on the following aspects: 1. Density: Density refers to the degree to which the gaps between particles in soil or asphalt concrete are effectively reduced; 2. Compaction depth; 3. Surface flatness; 4. Anti-deformation performance; 5. Durability.
[0004] When rolling a road, a steel wheel roller is generally used first, and then a rubber wheel roller is used; however, when constructing in an adverse climatic environment, the heat of the asphalt concrete on the road surface will be released quickly due to the low ambient temperature. Therefore, after the steel wheel roller has finished rolling, if the rubber wheel roller cannot accurately press the position where the steel wheel roller is pressing, the time difference when the rubber wheel roller presses on the asphalt concrete at each position is different. The greater the time difference, the lower the temperature of the asphalt concrete at that position, resulting in a large difference in the temperature of the asphalt concrete at various positions on the road surface when being pressed, that is, the asphalt concrete is not in an optimal temperature range when being rolled by the rubber wheel roller. If the asphalt concrete is not in an optimal temperature range when being pressed, it will affect the workability and bonding properties of the asphalt concrete, and thus affect the compaction effect of the asphalt concrete.

[0029] Figures 1 to 3 The road roller device and rolling system provided by the utility model are shown. As can be seen from the figure, the road roller device of the utility model includes a steel wheel roller 100 and a marker discharge unit 200. The marker discharge unit 200 is connected to the steel wheel roller 100, and has a accommodating chamber 2110 and a marker discharge outlet 2120 that can be connected to the accommodating chamber 2110; wherein, when the accommodating chamber 2110 accommodates a marker, the marker is suitable for being discharged from the marker discharge outlet 2120 to the road surface, so as to form a marking line that marks the driving track of the steel wheel roller 100 when the steel wheel roller 100 is driving.
[0030] During specific implementation, when the marker is contained in the accommodating chamber 2110, the marker is suitable for being discharged from the marker discharge port 2120 to the road surface. As the steel-wheel roller 100 travels, the marker will be continuously discharged to the road surface to form a marking line marking the travel trajectory of the steel-wheel roller 100. The marking line is equivalent to a guide line, and the driver of the rubber-wheel roller can drive the rubber-wheel roller along the marking line (or guide line) and perform rolling. For example, if the steel-wheel roller 100 travels to the left front of the road surface for rolling, the marking line is set to be inclined to the left from bottom to top, and the driver of the rubber-wheel roller can drive according to the marking line to make the rubber-wheel roller travel along the marking line to the left front of the road surface for rolling, thereby ensuring that the rubber-wheel roller can Accurately press the position where the steel wheel roller 100 presses, thereby, the time difference when the rubber wheel roller presses on the asphalt concrete at each position is basically the same, and the time for heat release is basically the same, thereby ensuring that the temperature of the asphalt concrete at each position on the road surface is basically consistent when being rolled by the rubber wheel roller. Therefore, the asphalt concrete at each position on the road surface can be in an optimal temperature range when being rolled by the rubber wheel roller. It can be understood that if the asphalt concrete is in an optimal temperature range when being pressed, the workability and bonding properties of the asphalt concrete are better, and therefore the compaction effect of the asphalt concrete is better, thereby solving the technical problem in the prior art that the compaction effect is poor due to the uneven temperature of the asphalt concrete at each position on the road surface when the rubber wheel roller is used for rolling.
[0031] In this embodiment, the steel wheel roller 100 can be a conventional steel wheel roller 100; the marker can be in powder form, such as cement or flour, etc.; it can also be in liquid form, such as a colored liquid formed by mixing color powder and tap water, or other conventional suitable substances, such as red ink, etc.
[0032] In this embodiment, the marker discharge unit 200 includes a receiving mechanism 210 and a discharge control mechanism 220 ; the receiving chamber 2110 and the marker discharge port 2120 are disposed in the receiving mechanism 210 ; and the discharge control mechanism 220 is connected to the receiving mechanism 210 .
[0033] According to one embodiment of the utility model, the accommodating mechanism 210 includes a accommodating box 211 and a partition plate 212; the accommodating chamber 2110 and the marker discharge port 2120 are arranged in the accommodating box 211; the partition plate 212 is located in the accommodating chamber 2110, and is connected to the chamber wall of the accommodating chamber 2110 to divide the accommodating chamber 2110 into a first accommodating sub-chamber 2101 and a second accommodating sub-chamber 2102, and to divide the marker discharge port 2120 into a first marker discharge sub-port 2121 and a second marker discharge sub-port 2122; the first accommodating sub-chamber 2101 accommodates a first marker; the second accommodating sub-chamber 2102 accommodates a second marker having a color different from that of the first marker; the emission control mechanism 220 is located at the first marker discharge sub-port 2121 and the second marker discharge sub-port 2122, and is suitable for opening or closing the first marker discharge sub-port 2121 and for opening or closing the second marker discharge sub-port 2122.
[0034] In specific implementation, since the steel wheel roller 100 generally rolls the road surface back and forth, if a marker of the same color (such as the first marker) is used for both reciprocating and rolling, the marking lines on the road surface are sometimes mixed together after the steel wheel roller 100 rolls back and forth once, so that the driver of the steel wheel roller 100 cannot distinguish whether the marking line is the way forward or the way back. Therefore, through the above-mentioned structural setting, the steel wheel roller 100 can roll forward (away from the starting point) and roll back and forth. When the first marker discharge sub-port 2121 is opened and the second marker discharge sub-port 2122 is closed, so as to draw a line with the first marker; when the steel wheel roller 100 is rolling back (towards the starting point), the second marker discharge sub-port 2122 can be opened and the first marker discharge sub-port 2121 can be closed, so as to draw a line with the second marker, so that the driver of the rubber wheel roller can distinguish the marking lines by the colors, ensuring that the rubber wheel roller can accurately reciprocate along the marking lines without deviation.
[0035] In this embodiment, the emission control mechanism 220 includes a first valve 221 and a second valve 222 ; the first valve 221 is disposed at the first marker discharge sub-port 2121 ; and the second valve 222 is disposed at the second marker discharge sub-port 2122 .

[0037] In specific implementation, the above-mentioned structural setting can facilitate people to observe the capacity of the first marker and the second marker.
[0038] According to an embodiment of the present invention, the accommodating box 211 is clamped to the side wall of the steel wheel roller 100; and the marker discharge port 2120 is arranged toward the road surface.

[0040] According to an embodiment of the present invention, the marker is in liquid form; it also includes a first liquid level gauge 300 and a second liquid level gauge 400; the first liquid level gauge 300 is disposed in the first accommodating sub-cavity 2101; the second liquid level gauge 400 is disposed in the second accommodating sub-cavity 2102.
[0041] In specific implementation, the above-mentioned structural setting can facilitate people to accurately determine the capacity of the first marker and the second marker.
[0042] According to one embodiment of the utility model, the roller device of the utility model may also include a controller and a warning unit; the controller is electrically connected to the first liquid level gauge 300 and the second liquid level gauge 400; the warning unit is located in the cab of the steel wheel roller 100, and is suitable for issuing a warning reminder when the first liquid level gauge 300 detects that the liquid level in the first accommodating sub-chamber 2101 is lower than the first preset value, and / or is suitable for issuing a warning reminder when the second liquid level gauge 400 detects that the liquid level in the second accommodating sub-chamber 2102 is lower than the second preset value.
[0043] In specific implementation, the above-mentioned structural setting can remind the driver of the rubber-tyred roller to add the first marker and the second marker.
