Abstract
Description
An asphalt penetration tester Technical Field
[0001] This utility model mainly relates to the technical field of asphalt testing equipment, specifically an asphalt penetration tester. Background Technology
[0002] In the production, application, and quality control of asphalt materials, penetration is a crucial physical performance indicator. It directly reflects the hardness and consistency of asphalt, and is of great significance for determining the applicable scope of asphalt, ensuring the quality of road engineering, and extending the service life of roads.
[0003] Currently, existing asphalt penetration testers on the market have certain limitations in structure and function. Some testers have simple sample placement structures, lacking precise limiting and fixing devices, which makes the sample prone to displacement or shaking during testing, thus affecting the accuracy and repeatability of the test results. For example, some testers only use simple slots or clamps to fix the sample cup. When the penetration testing device applies pressure, the sample cup may move slightly due to uneven force, causing deviations in the penetration depth measurement. Furthermore, existing testers also have shortcomings in sample replacement and ease of operation. The connection between the sample cup and the main body of the tester is not flexible enough, requiring considerable time and effort to disassemble and install when changing different samples, reducing testing efficiency. Moreover, the adjustment mechanisms of some testers are poorly designed and complex to operate, requiring professional personnel for adjustments, increasing the cost and difficulty of use.
[0004] Regarding testing accuracy, the existing testing instruments are not optimized enough, making it difficult to guarantee the stability of samples and the precision of the testing device during the testing process, resulting in certain errors in the test results. This may pose a potential quality risk for engineering projects with high requirements for asphalt quality.
[0005] In conclusion, developing an asphalt penetration tester with a reasonable structure, convenient operation, and high testing accuracy is of great practical significance. Summary of the Invention

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

The top of the annular slide rail 31 is symmetrically provided with limiting clamps 34, the bottom of the limiting clamps 34 is provided with at least one set of sliders 35, and the top end of the limiting clamps 34 and the top of one of the sliders 35 is provided with a handle 36 with a screw.
[0026] The top of the annular slide rail 31 is symmetrically embedded with a planar spiral arc segment groove 311, and the cross section of the planar spiral arc segment groove 311 is set in an inverted T shape; the inner wall of the planar spiral arc segment groove 311 is slidably connected to the outer wall of the slider 35.
[0027] The outer wall of the annular sidewall 32 is symmetrically provided with arc grooves 321, and the side of the arc groove 321 near the end of the planar spiral arc groove 311 is provided with a through hole; the side wall of the limiting clamping block 34 near the annular sidewall 32 is slidably connected to the inner wall of the arc groove 321.
[0028] The outer wall of the sample container 33 is slidably connected to the inner wall of the annular side wall 32, and the top opening of the sample container 33 is located at the bottom of the detection end 20.
[0029] The limiting clamp 34 has an overall arc-shaped structure. The bottom of the limiting clamp 34 is slidably connected to the top of the annular slide rail 31. The limiting clamp 34 has a mounting through hole 341 at one end with a screw handle 36. The limiting clamp 34 has a limiting groove 342 embedded at the bottom of the mounting through hole 341 at the other end with the screw handle 36.
[0030] The top of the slider 35 is located on the inner wall of the limiting groove 342. The top inner wall of the slider 35 is threadedly connected to the bottom of the screw-driven part of the screw handle 36. The bottom of the side wall of the slider 35 is provided with a limiting side block 351, and the bottom of the slider 35 is provided with a round block 352.
[0031] It should be noted that, in this embodiment, the detection end 20 provided at one end of the top of the control system console 10 is used to perform penetration detection on the asphalt sample; the sample placement end 30 provided at the other end of the top of the control system console 10 is used to place the asphalt sample to be tested.
[0032] The control system console 10 has an annular slide rail 31 at the other end of its top, which provides a sliding track for the limiting clamp 34; an annular sidewall 32 at the other end of its top, located on the inner wall of the annular slide rail 31, is used to support and position the sample holding cup 33; the sample holding cup 33 at the other end of its top, located on the inner wall of the annular sidewall 32, is used to hold asphalt samples, and its top opening is located at the bottom of the detection end 20 so that the detection end 20 can detect it.
[0033] The annular slide rail 31 has symmetrically arranged limiting clamps 34 at its top, and at least one set of sliders 35 at its bottom. The sliders 35 cooperate with the annular slide rail 31, allowing the limiting clamps 34 to slide on the annular slide rail 31. A screw-driven handle 36 is provided at one end of the top of one of the sliders 35. By rotating the screw-driven handle 36...
[0034] The position of the limiting clamp 34 can be fixed to increase the stability of the limiting clamp, thereby limiting and fixing the side wall of the sample holding cup 33.
[0035] The top of the annular slide rail 31 is symmetrically embedded with a planar spiral arc groove 311. The planar spiral arc groove 311 has an inverted T-shaped cross section. This design makes the sliding of the slider 35 in the planar spiral arc groove 311 more stable. At the same time, the slider 35 can be moved in the planar spiral arc groove 311 by rotating the screw handle 36, thereby driving the slider 35 to move up and down in the limiting groove 342.
[0036] The inner wall of the planar spiral arc groove 311 is slidably connected to the outer wall of the slider 35. This connection method not only ensures the smooth sliding of the limiting clamp 34 on the annular slide rail 31, but also improves the accuracy and stability of the position adjustment of the limiting clamp 34.
[0037] The outer wall of the annular sidewall 32 is symmetrically provided with arc grooves 321. The side of the arc groove 321 near the end of the planar spiral arc groove 311 is provided with a through hole, so that the limiting clamp 34 can cooperate with the arc groove 321 during the sliding process, which further improves the sliding stability and positional accuracy of the limiting clamp 34. When the limiting clamp 34 slides to the position of the through hole on one side of the end of the arc groove 311, it can achieve contact and clamping with the outer wall of the container cup 33.
[0038] The limiting clamp 34 has an overall arc-shaped structure, which allows it to better cooperate with the annular slide rail 31 and the sample holding cup 33, improving the limiting and fixing effect. The bottom of the limiting clamp 34 is slidably connected to the top of the annular slide rail 31, ensuring smooth sliding of the limiting clamp 34 on the annular slide rail 31.
[0039] The limiting clamp 34 has a screw handle 36 at one end with a mounting through hole 341 for installing and fixing the screw handle 36; the limiting clamp 34 has a limiting groove 342 embedded at the bottom of the mounting through hole 341 at the end with the screw handle 36, and the top of the slider 35 is located on the inner wall of the limiting groove 342, making the connection between the slider 35 and the limiting clamp 34 more stable, and at the same time facilitating the movement of the slider 35 within the limiting groove 342.
[0040] The top inner wall of the slider 35 is threadedly connected to the bottom of the screw-driven part of the screw-driven handle 36. By rotating the screw-driven handle 36, the slider 35 can move up and down within the limiting groove 342, thereby adjusting the friction between the bottom round block 352 of the limiting clamp 34 and the inner wall of the planar spiral arc groove 311, thus maintaining and fixing the limiting clamp 34. The bottom of the side wall of the slider 35 is provided with a limiting side block 351, which is used to limit the sliding range of the slider 35 within the limiting groove 342 and prevent the slider 35 from sliding out of the limiting groove 342. At the same time, it provides the necessary conditions for the screw-driven handle 36 to rotate. The bottom of the slider 35 is provided with a round block 352, which contacts the inner wall of the planar spiral arc groove 311, improving the stability of the slider 35 sliding within the planar spiral arc groove 311.
[0041] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
