Description

Technical Field

[0001] This application relates to the field of leveling devices, and in particular to a leveling device for asphalt softening points. Background Technology

[0002] The softening point of asphalt refers to the lowest temperature at which asphalt gradually softens from a solid state under heating conditions and reaches a specified flow state under a specific testing method. The softening point reflects the sensitivity of asphalt to high temperatures and its thermal stability, and is one of the important indicators for evaluating the high-temperature performance of asphalt.

[0003] The most commonly used method for determining the softening point of asphalt at present is the ring and ball method. The principle involves heating the asphalt, pouring it into a copper ring, and cooling it to room temperature to create an asphalt sample. A steel ball is then placed in the center of the asphalt sample, which is then immersed in a liquid medium. Under the pressure of the steel ball, the sample is heated at a constant rate. The temperature at which the asphalt softens and descends a specified vertical distance is the softening point. To ensure the accuracy of the test results, after the asphalt sample has cooled, excess asphalt on the surface of the copper ring is usually scraped off with a scraper.

[0004] Regarding the aforementioned technologies, the inventors believe that after the asphalt sample cools, it is difficult to smooth its surface with a regular scraper. Utility Model Content

[0005] To improve the efficiency of leveling excess asphalt on the surface of cooled asphalt samples, this application provides an asphalt softening point leveling device.

[0006] The asphalt softening point leveling device provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, when leveling the sample specimen, the operator first places the sample ring in the arrangement groove of the mounting base and pours asphalt into the sample ring. After cooling, the sample specimen is obtained. Then, the hot knife assembly is controlled to slide on the surface of the mounting base and level the asphalt on the upper side of the sample specimen. Finally, the ejector rod at the bottom of the mounting base is driven by the drive component to eject the sample specimen from the arrangement groove of the mounting base, thereby achieving the leveling of the asphalt on the surface of the sample specimen. Since the hot knife assembly has a heating function, it can heat the asphalt and reduce its hardness when it comes into contact with it, which helps to improve the efficiency of leveling excess asphalt on the surface of the cooled asphalt sample.

[0009] Optionally, the hot knife assembly includes a scraper section, a sliding section connected to one side of the scraper section, and an electric heating plate arranged in the scraper section for heating the scraper section; the scraper section has a heating groove on its top for arranging the electric heating plate and is fitted with a scraper top cover for covering the heating groove, and the scraper top cover has an arrangement through hole for passing through the external cable of the electric heating plate.

This allows the hot knife assembly to heat the asphalt and reduce its hardness when it comes into contact with the surface of the sample specimen, thereby helping to improve the efficiency of the hot knife assembly in scraping off excess asphalt on the surface of the cooled asphalt sample.

[0011] Optionally, one side of the mounting base is provided with a linear guide rail for sliding the hot knife assembly back and forth along a length direction parallel to the mounting base, and the bottom of the sliding part has a linear slider that cooperates with the linear guide rail.

[0013] Optionally, a first drive cylinder is mounted on the top of the mounting base for driving the hot knife assembly to slide back and forth along the linear guide.

[0014] By adopting the above technical solution, a first drive cylinder is installed on the top of the mounting base and the hot knife assembly is driven to slide back and forth along the linear guide rail by the first drive cylinder, which helps to improve the efficiency of the hot knife assembly in scraping the asphalt on the upper side of the sample specimen.

[0015] Optionally, the output end of the ejector rod is provided with a circular pad for ejecting the sample specimen out of the arrangement groove, and the top surface of the circular pad has an arrangement plane for the bottom of the sample specimen to abut against.

[0016] By adopting the above technical solution, a circular pad is set at the output end of the ejector rod for the bottom of the sample specimen to abut against, which helps to reduce the risk of asphalt in the sample specimen overflowing from the bottom of the sample ring, thereby helping to improve the durability of the asphalt softening point leveling device.

[0021] Optionally, the top of the abutment plate has a guide surface.

[0022] By adopting the above technical solution, the guide surface is designed so that the asphalt scraped off by the hot knife assembly can fall into the collection tank along the guide surface, thereby further improving the collection efficiency of the asphalt scraped off by the hot knife assembly.

[0023] Optionally, the number of arrangement slots is four, and they are evenly spaced along the length of the mounting base.

[0024] By adopting the above technical solution, four arrangement slots are evenly spaced along the length of the mounting base on the top of the mounting base, which helps to improve the efficiency of scraping off excess asphalt on the surface of the cooled asphalt sample.

In this embodiment, the damping ring 3222 installed in the damping ring groove 3221 is a rubber ring.

[0044] The implementation principle of the asphalt softening point leveling device in this application embodiment is as follows: When leveling a sample specimen, the operator first places the sample ring in the arrangement groove 12 of the mounting base 1 and pours asphalt into the sample ring. After cooling, the sample specimen is obtained. Then, the hot knife assembly 2 is controlled to slide on the surface of the mounting base 1 and level the asphalt on the upper side of the sample specimen. The hot knife assembly 2 scrapes the scraped asphalt into the collection assembly 3 along the sliding direction. Finally, the driving component 15 drives the ejector rod 14 at the bottom of the mounting base 1 to eject the sample specimen from the arrangement groove 12 of the mounting base 1, thereby achieving the leveling of the asphalt on the surface of the sample specimen. Since the hot knife assembly 2 has a heating function, it can heat the asphalt and reduce its hardness when it comes into contact with it, which helps to improve the efficiency of leveling excess asphalt on the surface of the cooled asphalt sample.
