Description

Technical Field

[0001] This utility model relates to the field of asphalt testing technology, and in particular to a CNC testing device for intelligent asphalt testing. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid and a waterproof, moisture-proof, and corrosion-resistant organic binder used in coatings, plastics, rubber, and road paving. In civil engineering, asphalt is a widely used waterproofing and corrosion-resistant material, primarily applied to waterproofing roofs, floors, and underground structures, as well as for protecting timber and steel. Asphalt is also a widely used pavement structural binder in road engineering. When mixed with mineral materials of different compositions in specific proportions, it can form asphalt pavements with various structures. When conducting penetration tests on asphalt, an asphalt penetration tester is typically used. This tester can perform intelligent numerical control testing of asphalt using a built-in computer-controlled testing device.

[0003] Existing asphalt penetration testers require placing a water container filled with test water on the tester's platform, then placing a sample dish containing asphalt into the water container. The position of the sample dish within the water container needs to be adjusted multiple times based on the needle's position to ensure smooth penetration into the asphalt. However, this method of repeatedly adjusting the sample dish is cumbersome and increases the test time. Therefore, we propose a CNC testing device for intelligent asphalt testing. Utility Model Content

[0004] The main objective of this invention is to provide a CNC testing device for intelligent asphalt testing. A positioning mechanism is installed at the needle-dropping platform of the penetration meter body. This positioning mechanism can be assembled at the needle-dropping platform to assist in the positioning of the asphalt container. The U-shaped limiting frame of the positioning mechanism, equipped with an arc-shaped limiting strip, can enter a water container placed on the surface of the penetration meter body under the drive of an electric actuator. Then, the positioning cylinder, carrying the asphalt-filled sample container, quickly enters the U-shaped limiting frame below the test needle for positioning. This allows the penetration meter body to quickly complete the positioning of the test asphalt, facilitating rapid positioning tests of asphalt at the penetration meter body and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

A water container is placed on the surface of the needle penetration meter body below the test needle. The device also includes a positioning mechanism, which comprises an L-shaped mounting plate, an electric actuator, a connecting column, a T-shaped plate, rubber reinforcing strips, a connecting plate, a U-shaped limiting frame, an arc limiting strip, and a positioning cylinder. The top of the needle drop platform is secured by bolts. An L-shaped hanging plate is attached, and an electric actuator is welded to the outside of the vertical plate of the L-shaped hanging plate, resting against the outside of the needle drop platform. A connecting column is welded to the telescopic head of the electric actuator, and a T-shaped groove is opened on the outside of the connecting column. A T-shaped plate welded to the surface of the connecting plate is inserted into the cavity of the T-shaped groove, and a rubber reinforcing strip is glued to the outside of the vertical plate of the T-shaped plate. The connecting plate is welded between the straight plates of the U-shaped limiting frame, and an arc limiting strip is fixed between the straight plates of the U-shaped limiting frame. The U-shaped limiting frame is pressed into the water container, and a positioning cylinder is inserted between the U-shaped limiting frame and the arc limiting strip.

[0007] Furthermore, the length of the T-shaped plate is greater than the depth of the T-shaped groove, and the depth of the T-shaped groove is less than the diameter of the connecting column.

[0008] By adopting the above technical solution, the T-shaped plate can be smoothly inserted into the T-shaped groove for mounting, and the T-shaped plate can expose the T-shaped groove of the connecting column for easy insertion and removal.

[0009] Furthermore, two sets of rubber reinforcing strips are symmetrically bonded to the vertical body of the T-shaped plate, and the rubber reinforcing strips are triangular strips.

[0010] By adopting the above technical solution, the T-shaped plate can be embedded in the T-shaped groove with two sets of rubber strips, ensuring that the T-shaped plate can be firmly clamped in the T-shaped groove.

[0011] Furthermore, the straight plate of the arc-limiting strip is welded to the straight plate of the U-shaped limiting frame, and the inner arc surface of the arc-limiting strip faces the inner arc surface of the U-shaped limiting frame;

[0012] By adopting the above technical solution, the arc-shaped limiting strip and the U-shaped limiting frame can be welded together to position and clamp the positioning cylinder.

[0013] Furthermore, the top plate of the L-shaped hanging plate presses against the top of the needle drop table, and an installation hole for screwing bolts is provided between the L-shaped hanging plate and the top wall of the needle drop table.

[0014] By adopting the above technical solution, the L-shaped mounting plate is bolted to the top of the needle drop table to support the electric actuator.

[0015] Furthermore, the diameter of the connecting column is the same as the diameter of the telescopic rod of the electric actuator, and the upper end face of the connecting column is welded to the bottom end face of the telescopic rod of the electric actuator.

[0016] By adopting the above technical solution, after the connecting column and the telescopic rod of the electric actuator are adapted and welded, it is ensured that the electric actuator can be raised and lowered by carrying the connecting column through the telescopic rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention features a positioning mechanism at the needle drop platform of the penetration tester. This positioning mechanism can be assembled at the needle drop platform to assist in the positioning of the asphalt container. The U-shaped limiting frame of the positioning mechanism, which has an arc-shaped limiting strip, can enter the water container placed on the surface of the penetration tester under the drive of the electric push rod. Then, the positioning cylinder, carrying the sample container containing asphalt, quickly enters the U-shaped limiting frame below the test needle for positioning. This allows the penetration tester to quickly complete the positioning of the test asphalt, facilitating the rapid positioning test of asphalt at the penetration tester.

[0019] Furthermore, the T-shaped plate at the junction of the U-shaped limiting frame and the connecting column below the electric actuator can be positioned and clamped, making it convenient for the U-shaped limiting frame to be disassembled and cleaned after the asphalt penetration test.

There is an L-shaped hanging plate 6, and an electric push rod 7 is welded to the outside of the vertical plate of the L-shaped hanging plate 6, which rests against the outside of the needle drop platform 2. A connecting column 8 is welded to the telescopic rod head of the electric push rod 7, and a T-shaped groove 9 is opened on the outside of the column of the connecting column 8. A T-shaped plate 10 welded to the surface of the connecting plate 12 is inserted into the groove cavity of the T-shaped groove 9, and a rubber rib strip 11 is glued to the outside of the vertical plate of the T-shaped plate 10. The connecting plate 12 is welded between the straight plates of the U-shaped limiting frame 13, and an arc limiting strip 14 is fixed between the straight plates of the U-shaped limiting frame 13. The U-shaped limiting frame 13 is pressed into the water container 4, and a positioning cylinder 15 is inserted between the U-shaped limiting frame 13 and the arc limiting strip 14.

[0026] Wherein, the length of the T-shaped plate 10 is greater than the depth of the T-shaped groove 9, and the depth of the T-shaped groove 9 is less than the diameter of the column 8.

[0027] By adopting the above technical solution, the T-shaped plate 10 can be smoothly inserted into the T-shaped groove 9 for mounting, and the T-shaped plate 10 can expose the T-shaped groove 9 of the connecting column 8 for easy insertion and removal.

[0028] Among them, two sets of rubber reinforcing strips 11 are symmetrically bonded to the vertical plate of the T-shaped plate 10, and the strip of the rubber reinforcing strip 11 is a triangular strip.

[0029] By adopting the above technical solution, the T-shaped plate 10 can be embedded in the T-shaped groove 9 with two sets of rubber strips 11, ensuring that the T-shaped plate 10 can be firmly installed in the T-shaped groove 9.
