Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway engineering technology, specifically to an asphalt compaction vehicle. Background Technology
[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Asphalt is commonly used for highway paving, and after paving, it needs to be compacted using compaction trucks.
[0003] Asphalt concrete pavement, also commonly known as tarpaulin road or asphalt road, is a widely used road surface. Asphalt is a complex, dark brown mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form. After paving, asphalt pavement usually requires multiple compaction processes to ensure the smoothness of the road surface. The current compaction method usually uses a road roller. During the asphalt compaction process, the steel wheel carries heat, which helps the asphalt become softer and easier to compact. However, the steel wheel usually takes a certain amount of time to heat up, and the cold steel wheel absorbs the heat from the asphalt, accelerating the cooling of the asphalt and affecting subsequent compaction. This can easily lead to uneven compaction and affect the smoothness of the road surface. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide an asphalt compaction vehicle that solves the problem that steel wheels usually require a certain amount of time to heat up, and the cold steel wheels will absorb the heat of the asphalt, accelerating the cooling of the asphalt and affecting subsequent compaction, which can easily lead to incomplete compaction and affect the smoothness of the road surface.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an asphalt compaction vehicle, comprising a roller and an oil pump. A mounting bracket is installed on the outer side of the roller, and scrapers are installed at both ends of the mounting bracket. A cooling device is installed inside the mounting bracket, and a guide rod is welded to the inner side of the mounting bracket. A hydraulic spring is connected to the end of the cooling device away from the roller, and a heating wire is installed inside the cooling device. The oil pump is installed inside the cooling device, and a heat-conducting pipe is connected to the output end of the oil pump. The other end of the heat-conducting pipe is connected to the cooling device. A drive motor is installed in the middle of the cooling device, and a brush plate is connected to the output end of the drive motor.
[0006] The beneficial effects of this utility model are as follows: the vehicle moves the roller, and during the movement of the roller, the scraper scrapes off the impurities adhering to it. The drive motor drives the brush plates to rotate, and the brush plates rotate synchronously, thereby cleaning the roller again and ensuring its cleanliness during operation. This results in a comprehensive and reliable cleaning of the roller.
[0007] The heating wire heats the heat-conducting liquid inside the cooling device. After heating, the oil pump transports the liquid inside the cooling device to the inside of the heat-conducting pipe to heat the rolling steel wheel. The liquid then flows back into the cooling device, reducing the occurrence of subsequent rolling caused by the steel wheel being too cold.
[0008] To facilitate the heating of the heat transfer fluid inside the cooling device:
[0009] As a further improvement to the above technical solution: the heating wires are evenly distributed inside the cooling device.
[0010] The beneficial effect of this improvement is that the equally spaced heating wires can heat the heat-conducting liquid inside the cooling device evenly and quickly.
[0011] To facilitate the sliding of the cooling device:
[0012] As a further improvement to the above technical solution: the guide rod is symmetrically arranged about the centerline of the cooling device.
[0013] As a further improvement to the above technical solution: the mounting bracket is provided with a sliding groove near the cooling device, and the cooling device and the mounting bracket are connected by the sliding groove to form a locking and sliding mounting structure.
[0014] The beneficial effects of this improvement are: the guide rods symmetrically arranged along the centerline can work with the slide to guide and limit the cooling device when it slides, ensuring the stability of the cooling device during sliding.
[0015] To ensure the heat transfer pipes heat the steel wheel:
[0016] As a further improvement to the above technical solution: the heat-conducting pipe and the axis of the road roller are arranged parallel to each other.
[0017] The beneficial effect of this improvement is that the parallel arrangement of the heat-conducting pipes can make the heating of the steel wheel more uniform and comprehensive.
[0018] To ensure the smooth operation of the cooling device:
[0019] As a further improvement to the above technical solution: the cooling device and the road roller are arranged in parallel to each other.
[0020] The beneficial effect of this improvement is that the parallel arrangement allows the cooling device to smoothly fit against the road roller under the push of the hydraulic spring.
[0021] To facilitate the cleaning of the road roller:
[0022] As a further improvement to the above technical solution: the brush plates are evenly distributed on the outside of the cooling device, and the brush plates are connected to the cooling device through bearings.
[0023] As a further improvement to the above technical solution: the brush plates are driven by a synchronous belt.
[0024] The beneficial effects of this improvement are: the equally spaced brush plates can thoroughly and reliably clean the road roller; the bearing connection can make the brush plates rotate more reliably and smoothly; and the synchronous belt can make the brush plates rotate synchronously.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0032] like Figure 1-5As shown, an asphalt compaction vehicle includes a roller 1 and an oil pump 3. A mounting bracket 11 is installed on the outer side of the roller 1, and scrapers 12 are installed at both the upper and lower ends of the mounting bracket 11. A cooling device 2 is installed inside the mounting bracket 11, and a guide rod 21 is welded to the inner side of the mounting bracket 11. A hydraulic spring 22 is connected to the end of the cooling device 2 away from the roller 1. An electric heating wire 23 is installed inside the cooling device 2. The oil pump 3 is installed inside the cooling device 2, and a heat-conducting pipe 31 is connected to the output end of the oil pump 3. The other end of the heat-conducting pipe 31 is connected to the cooling device 2. A drive mechanism is installed in the middle of the cooling device 2. Motor 4, with a brush plate 41 connected to its output end, drives the vehicle to move the roller 1. During the movement of the roller 1, the scraper 12 scrapes off the impurities adhering to it. The drive motor 4 drives the brush plate 41 to rotate, and the brush plates 41 rotate synchronously to clean the roller 1 again, ensuring its cleanliness during operation and providing a comprehensive and reliable cleaning. The heating wire 23 heats the heat transfer fluid inside the cooling device 2. After heating, the oil pump 3 delivers the liquid from the cooling device 2 to the heat transfer pipe 31 to heat the roller 1 again before it flows back into the cooling device 2, reducing the impact of the steel roller on the roller's movement. Low wheel temperature can affect subsequent compaction. The heating wires 23 are evenly distributed inside the cooling device 2, allowing for uniform and rapid heating of the heat-conducting liquid inside. The guide rods 21 are symmetrically arranged about the centerline of the cooling device 2. The mounting bracket 11 has a sliding groove near the cooling device 2, and the cooling device 2 and the mounting bracket 11 are connected by the sliding groove to form a sliding engagement structure. The symmetrically arranged guide rods 21, in conjunction with the sliding groove, guide and limit the cooling device 2 during sliding, ensuring its stability. The heat-conducting pipe 31 connects to the road roller 1. The axes of the heat pipes 31 are arranged in parallel, which allows for more uniform and comprehensive heating of the steel wheel. The cooling device 2 and the rolling steel wheel 1 are also arranged in parallel, which allows the cooling device 2 to smoothly fit against the rolling steel wheel 1 under the push of the hydraulic spring 22. The brush plates 41 are evenly distributed on the outside of the cooling device 2 and are connected to the cooling device 2 by bearings. The brush plates 41 are driven by a synchronous belt. The evenly distributed brush plates 41 can clean the rolling steel wheel 1 comprehensively and reliably. The bearing connection makes the rotation of the brush plates 41 more reliable and stable, and the synchronous belt allows the brush plates 41 to rotate synchronously.
[0033] The working principle of this utility model is as follows: When using this device, the vehicle drives the roller 1 to move. During the movement of the roller 1, the scraper 12 scrapes off the impurities adhering to the roller 1, thereby thoroughly and reliably cleaning the roller 1. After cleaning, the heating wire 23 heats the heat-conducting liquid inside the cooling device 2. After heating, the oil pump 3 delivers the liquid inside the cooling device 2 to the inside of the heat-conducting pipe 31 to heat the roller 1 and then flows back into the cooling device 2, reducing the phenomenon of the roller being too cold and affecting subsequent compaction. During the vehicle operation, the hydraulic spring 22 pushes the cooling device 2 to reliably and smoothly adhere to the roller 1, ensuring that the heat-conducting pipe 31 heats the roller 1. At this time, the drive motor 4 drives the brush plate 41 to rotate. The brush plates 41 rotate synchronously, thereby cleaning the roller 1 again and ensuring the cleanliness of the roller 1 during operation.
