Description

Technical Field

[0001] The utility model relates to the technical field of road rollers, in particular to a road roller for asphalt roads. Background Art

[0002] A road roller, also known as a soil roller, is a type of road construction equipment, which is divided into two types: steel wheel type and tire type. Among engineering machinery, road rollers belong to the category of road equipment and are widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-viscous and viscous soils, roadbed stabilized soils, and asphalt concrete pavement layers. With the gravity of the machine itself, road rollers are suitable for various compaction operations, causing the rolled layer to be permanently deformed and compacted.

[0003] At present, when the existing road roller is squeezing the asphalt road, asphalt may adhere to the surface of the roller, so the present application proposes a road roller for asphalt roads to solve this problem. Utility Model Content

[0004] The utility model aims to provide a roller for asphalt roads in view of the defects in the prior art.

[0005] The technical scheme of the utility model is: a roller for asphalt roads, comprising a roller body, the roller body comprising a pressure roller and two first mounting frames, the first mounting frame being fixed on the roller body, and the pressure roller being mounted between the two first mounting frames; a second mounting frame being fixedly mounted on the tops of the two first mounting frames, an oil storage tank being fixedly mounted on the inner top side of the second mounting frame, a first oil inlet pipe being connected to the top of the oil storage tank, and an oil pump being mounted on the bottom thereof; a second oil inlet pipe being inserted into the oil storage tank at the liquid inlet end of the oil pump, and a second oil outlet pipe being connected to the liquid outlet end thereof; a horizontally arranged shunt pipe being connected to the lower end of the second oil outlet pipe, and a plurality of first oil outlet pipes being fixedly mounted on the bottom of the shunt pipe;

[0006] A horizontal brush is also installed inside the second mounting frame. The brush is located directly below the diversion pipe, and the bottom of the brush is attached to the outer wall of the pressure roller.

[0007] Preferably, the top cover of the first oil inlet pipe is provided with a mesh cover.

[0008] Preferably, vertical mounting plates are provided at both ends of the brush, and the mounting plates are in contact with the inner wall of the second mounting frame. The second mounting frame is an inverted U-shape, and bolts are installed on both sides thereof; the bolts horizontally penetrate the second mounting frame and are threadedly connected to the mounting plate.

[0009] Preferably, the brush is provided with a plurality of vertical circular holes corresponding one-to-one to the first oil outlet pipes.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The device adds oil into the oil storage tank through the first oil inlet pipe, and extracts the oil through the oil pump. The extracted oil flows to each first oil outlet pipe through the diversion pipe and is sprayed out from the outlet of the first oil outlet pipe; during the rotation of the pressure roller, the brush evenly applies the oil to the surface of the pressure roller, thereby lubricating the surface of the pressure roller and preventing asphalt from adhering to the surface of the pressure roller; the brush of the device can be removed by removing only two bolts, which is convenient for quick disassembly and replacement.

DETAILED DESCRIPTION

[0018] The utility model is further described below with reference to the accompanying drawings and embodiments. Embodiment 1

[0019] Reference Figure 1-2 As shown, a roller for asphalt roads includes a roller body 1, the roller body 1 includes a pressure roller 4 and two first mounting frames 2, the first mounting frame 2 is fixed on the roller body 1, and the pressure roller 4 is installed between the two first mounting frames 2; a second mounting frame 3 is fixedly installed on the top of the two first mounting frames 2, an oil storage tank 5 is fixed on the inner top side of the second mounting frame 3, the top of the oil storage tank 5 is connected to a first oil inlet pipe 6, and an oil pump 8 is installed at the bottom; the liquid inlet end of the oil pump 8 is connected to a second oil inlet pipe 9 inserted into the oil storage tank 5, and the liquid outlet end of the oil pump 8 is connected to a second oil outlet pipe 10; the lower end of the second oil outlet pipe 10 is connected to a horizontally arranged shunt pipe 11, and a plurality of first oil outlet pipes 12 are fixedly installed at the bottom of the shunt pipe 11.

[0020] A horizontal brush 13 is also installed inside the second mounting frame 3, and the brush 13 is located directly below the shunt pipe 11, and its bottom is attached to the outer wall of the pressing roller 4. The brush 13 is attached to the pressing roller 4 as a whole, without a working blind area, and the oiling effect is better.

[0021] In more detail, the top cover of the first oil inlet pipe 6 is provided with a mesh cover 7, which ensures air intake while also reducing the possibility of dust entering the oil storage tank 5.

[0022] When in use, oil is added to the oil storage tank 5 through the first oil inlet pipe 6. When the roller body 1 is moving slowly, the oil pump 8 is started regularly. The oil pump 8 extracts part of the oil in the oil storage tank 5 through the second oil inlet pipe 9. The extracted oil flows to each first oil outlet pipe 12 through the diversion pipe 11 and is sprayed onto the brush 13 from the outlet of the first oil outlet pipe 12. When the pressure roller 4 rotates, the brush 13 evenly applies the oil to the surface of the pressure roller 4, thereby lubricating the surface of the pressure roller 4 and preventing asphalt from adhering to the surface of the pressure roller 4. Embodiment 2

[0023] As a preferred embodiment of the present utility model, this embodiment optimizes the structure of the brush 13 on the basis of the first embodiment, specifically:

[0024] Reference Figure 3-5 As shown, in this embodiment, vertical mounting plates 14 are provided at both ends of the brush 13, and the mounting plates 14 are in contact with the inner wall of the second mounting frame 3. The second mounting frame 3 is in an inverted U shape, and bolts 15 are installed on both sides thereof; the bolts 15 horizontally penetrate the second mounting frame 3 and are threadedly connected to the mounting plates 14. The mounting plates 14 and the bolts 15 are used to fix the brush 13 and allow the brush 13 to be quickly disassembled and replaced.

[0025] In addition, the brush 13 is provided with a plurality of vertical circular holes 1301 corresponding to the first oil outlet pipe 12. During the rotation of the pressure roller 4, the oil sprayed from the first oil outlet pipe 12 falls on the surface of the pressure roller 4 through the circular holes 1301, and the brush 13 evenly applies the oil on the surface of the pressure roller 4, thereby improving the effect of preventing asphalt from sticking.

[0026] The present invention is not limited to the above-mentioned embodiments. Within the knowledge scope of those skilled in the art, various changes can be made without departing from the purpose of the present invention. The changed contents still belong to the protection scope of the present invention.
