Description

Technical Field

[0001] This utility model belongs to the field of asphalt ductility testing, and specifically relates to an asphalt ductility testing device for highway engineering. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as buildings, workshops, and other service facilities used for construction, maintenance, and monitoring. In order to facilitate the construction of highway engineering, some construction equipment for highway engineering has been designed, including asphalt ductility testing devices for highway engineering.

[0003] Chinese Patent No. CN221781997U discloses an asphalt ductility testing frame, belonging to the field of asphalt ductility testing technology for highway engineering. It includes a counterweight base, with a scale rod fixedly connected to one side of the upper surface of the counterweight base. A limiting groove is formed on the outer wall of the scale rod. A placement opening is formed through the interior of the counterweight base, and symmetrical adsorption grooves are formed above the placement opening. A receiving tray is provided inside the placement opening. Asphalt leaks out through holes at the bottom of the first and second placement sleeves, allowing workers to observe the ductility of the asphalt in real time. This enables workers to adjust the asphalt mix ratio in a timely manner during actual production to ensure that its ductility meets requirements, thereby improving the quality of asphalt paving. By adjusting the height of the sliding sleeve, workers can set the maximum length of asphalt ductility. This height-adjustable design allows for flexible control of the asphalt ductility according to specific requirements and working conditions to adapt to different road construction needs.

[0004] As can be seen from the above structure, by adjusting the height of the sliding sleeve, the operator can set the maximum length of asphalt extension. This height adjustment design allows for flexible control of the asphalt ductility according to specific requirements and working conditions to adapt to different road construction needs. However, the above device is adjusted by the sliding sleeve and the knob, and the stability of this adjustment method is not good, so it cannot achieve a stable adjustment effect on the first placement sleeve during the experiment.

[0009] As a preferred technical solution, a hinge seat is fixedly connected to the upper end of each mounting edge, and a lifting rod is fixedly connected to the other end of each hinge seat. The lifting rod is rotatably connected to the mounting edge through the hinge seat.

[0010] As a preferred technical solution, movable handles are fixedly connected to both sides of the upper end of the plate, and anti-slip pads are fixedly connected to the outer surface of the movable handles. The lower end of the movable handles is fixedly connected to the plate by screws.

[0011] As a preferred technical solution, each corner of the panel is provided with a mounting through hole, and a mounting screw is inserted into the mounting through hole. The mounting screw passes through the mounting through hole and is threadedly connected to the base layer. A rubber pad is fixedly connected to the lower end of the panel.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this utility model, through its adjustable component, allows for the adjustment of the height between the holding box and the collection box during use. By holding the handle and rotating the turntable, the adjusting screw fixedly connected to the turntable rotates, causing the adjusting threaded part to slide on the surface of the adjusting screw. As the adjusting threaded part moves, it drives the adjusting connecting rod to move, which in turn moves the holding box, thereby allowing the distance between the collection box and the holding box to be adjusted.

[0016] Secondly, this utility model places asphalt inside a container and then observes the speed at which the asphalt flows out of the testing port to test its ductility. This allows workers to adjust the asphalt mix ratio in a timely manner during actual production to ensure that its ductility meets the requirements, thereby improving the quality of asphalt paving. At the same time, the falling asphalt will enter the collection box for collection, making it easy to clean the tested asphalt after the test. The collection box is snapped onto the upper end of the bracket, making it easier to remove, and the lifting handle allows for better movement of the collection box. Attached Figure Description

The lower end of the mounting edge 15 is fixedly connected to the mounting rod 16. The upper end of the bracket 2 is provided with the mounting slot 14. The mounting slot 14 and the mounting rod 16 are interlocked. The mounting rod 16 and the mounting slot 14 make it easy to install the collection box 3 onto the upper end of the bracket 2. At the same time, the collection box 3 can be easily disassembled by the interlocking method.

[0024] refer to Figure 2 The upper end of each mounting edge 15 is fixedly connected to a hinge seat 17, and the other end of each hinge seat 17 is fixedly connected to a lifting rod 18. The lifting rod 18 is rotatably connected to the mounting edge 15 through the hinge seat 17. The lifting rod 18 makes it easy to pick up the collection box 3.

[0025] refer to Figure 1 and Figure 3 Both sides of the upper end of the plate 1 are fixedly connected to movable handles 20, and the outer surface of the movable handles 20 is fixedly connected to anti-slip pads. The lower end of the movable handles 20 is fixedly connected to the plate 1 by screws. When moving, the device can be moved through the movable handles 20, and the anti-slip pads can prevent the device from slipping when moving.

[0026] refer to Figure 2 and Figure 3 Each corner of the panel 1 is provided with a mounting through hole 12. A mounting screw 13 is inserted into the mounting through hole 12. The mounting screw 13 passes through the mounting through hole 12 and is threaded to the base layer. A rubber pad is fixedly connected to the lower end of the panel 1.

The installation rod 16 and slot 14 allow for easy installation of the collection box 3 onto the upper end of the bracket 2. The collection box 3 can also be easily disassembled via a plug-in connection. Then, asphalt is placed inside the holding box 8, and the ductility of the asphalt is tested by observing the speed at which it flows out of the detection port 19. This allows workers to adjust the asphalt mix ratio in a timely manner during actual production to ensure its ductility meets requirements, thereby improving the quality of asphalt paving. Simultaneously, any falling asphalt enters the collection box 3 for collection, facilitating easy cleaning of the tested asphalt after testing. When it is necessary to clean the holding box... When adjusting the height of the collection box 3 and the container 8, hold the handle 7 and rotate the turntable 5. The rotation of the turntable 5 will cause the adjusting screw 43, which is fixedly connected to it, to rotate. This will cause the adjusting threaded part 44 to slide on the surface of the adjusting screw 43. As the adjusting threaded part 44 moves, it will drive the adjusting connecting rod 45 to move, which will move the container 8. This will allow the distance between the collection box 3 and the container 8 to be adjusted. The limiting slide rod 10 and the limiting slide groove 11 can limit the container 8, making the sliding more stable and providing support for the container 8. After use, the collection box 3 can be moved more easily by the lifting handle.
