Description

Technical Field

[0001] This utility model relates to the field of road foundation compaction technology, and in particular to road foundation compaction structures suitable for different terrains. Background Technology

[0002] Road foundation compaction involves using mechanical equipment such as road rollers to compact the road foundation, using the weight and vibration of the machinery to densify the foundation materials. This is the most commonly used compaction method, suitable for large-area roadbed and base course construction. However, in some special terrains such as steep slopes and high embankments, if the vibratory compactor is not well adapted, safety accidents such as rollover and landslides may occur. Therefore, road foundation compaction structures suitable for different terrains are needed.

[0003] At large highway construction sites, during the subgrade and base course construction phases, the construction team quickly deploys multiple road rollers. First, static rollers compact the subgrade at a stable speed using their own weight, while workers closely monitor the data and compaction status. Then, vibratory rollers are started, their parameters adjusted, and they compact the subgrade along a specific trajectory. The vibration causes the material particles to rearrange and fill voids, making the base material dense. The base course construction follows the same process, laying a solid foundation for subsequent construction.

[0004] In existing technologies, some road foundation compaction structures encounter varying terrain conditions during use, such as slopes. On sloping terrain, the operation of the compaction equipment becomes more difficult. Operators need to expend more effort to control the equipment's movement and operation, maintaining its stability and correct working direction. This leads to slower operation speeds and extended construction time. Therefore, to address these shortcomings, a road foundation compaction structure suitable for different terrains is proposed to solve the aforementioned problems. Utility Model Content

A drive assembly 1 is fixedly connected inside one of the vertical plates 5. A semi-circular ring 8 is fixedly connected to the left side of the drive assembly 1. The drive assembly 1 includes a motor 6, which provides a drive source.

[0034] Motor 6 is externally fixedly connected to the interior of one of the upright plates 5 and secured by welding, ensuring stable operation. A rotating shaft 7 is fixedly connected to the drive end of motor 6, rotating by starting motor 6. The left side of rotating shaft 7 is fixedly connected to the right side of semi-circular ring 8, transmitting rotational force to semi-circular ring 8. The left end of semi-circular ring 8 is rotatably connected to the interior of another upright plate 5 via a pin, providing support for semi-circular ring 8. A drive assembly 2 is fixedly connected to the interior of one of the right-angle plates 2, with a semi-circular ring 11 fixedly connected to its front. Drive assembly 2 includes motor 9, which provides the drive source. Motor 9 is externally fixedly connected to the interior of one of the right-angle plates 2 and secured by welding, ensuring stable operation. A rotating shaft 10 is fixedly connected to the drive end of motor 9, rotating by starting motor 9.

[0035] The front side of the rotating shaft 10 is fixed to the rear side of the semicircular ring 11, transmitting rotational force to the semicircular ring 11 via the rotating shaft 10. The front end of the semicircular ring 11 is rotatably connected to the interior of another right-angle plate 2 via a pin, which provides support for the semicircular ring 11. Both the first semicircular ring 8 and the second semicircular ring 11 have semicircular openings 12 inside, providing space for movement within them. A ball 13 is slidably connected to the outside of the arc plate 4, allowing the ball 13 to rotate stably due to the constraint of the arc plate 4. Two limiting openings 14 are provided inside the ball 13, providing space for movement within it. A transmission block 15 is slidably connected inside the ball 13, guiding its movement through the limiting openings 14 inside the ball 13. The arc-shaped plate 4 and the transmission block 15 are externally slidably connected inside two limiting openings 14. The limiting openings 14 restrict the movement of the arc-shaped plate 4 and the transmission block 15, allowing them to move stably. A cylinder 16 is fixedly connected to the bottom side of the transmission block 15 via a connecting shaft 25. The cylinder 16 provides the drive source. The drive end of the cylinder 16 is fixedly connected to the foundation rammer body 17. Starting the cylinder 16 drives the foundation rammer body 17 to perform linear motion.

[0036] Reference Figure 1 , Figure 2 and Figure 5The support platform 1 has strip-shaped openings 18 at both its left and right ends, allowing users to easily move the support platform 1 by inserting their fingers into the openings. Support legs 19 are fixedly connected to both the left and right ends of the bottom side of the support platform 1 via welding, providing support for the legs 19. An electric push rod 20 is fixedly connected to the top of each support leg 19, providing the driving source. A transmission plate 21 is fixedly connected to the drive end of the electric push rod 20, driving the transmission plate 21 to slide. Fixed plates 22 are fixedly connected to both the front and rear sides of the transmission plate 21, transmitting the sliding force to the two connected fixed plates 22. The top sides of the two fixed plates 22 contact the bottom sides of the support legs 19. Limiting plates 23 are fixedly connected to the top sides of the fixed plates 22. The two limiting plates 23 are externally slidably connected to the interior of the front and rear ends of the support legs 19, allowing the limiting plates 23 to slide stably due to the constraint of the support legs 19. An auxiliary wheel 24 is rotatably connected inside the fixed plate 22, which facilitates the movement of the entire device. The connecting shaft 25 is externally slidably connected inside the two semicircular openings 12. Through the restriction of the semicircular openings 12, the connecting shaft 25 can transmit force to the first semicircular ring 8 and the second semicircular ring 11.

[0037] Working principle: The starting motor 6 drives the rotating shaft 7 to rotate, which in turn drives the semi-circular ring 8 to rotate back and forth. Then, the connecting shaft 25 drives the transmission block 15 to guide the ball 13 to rotate. At the same time, the starting motor 9 drives the rotating shaft 10 to rotate, which in turn drives the semi-circular ring 11 to rotate. At this time, the connecting shaft 25 can also rotate under the restriction of the transmission block 15. This allows the connecting shaft 25 to drive the foundation rammer body 17 to make multi-angle adjustments through the cylinder 16. The cylinder 16 is also started to drive the foundation rammer body 17 to make distance adjustments, so that it can adapt to different terrain angles, reduce the operation of the adjustment device, and thus improve work efficiency.

[0038] Meanwhile, when the entire device is tilted, the electric push rod 20 drives the transmission plate 21 to slide through the tilted bottom end, and then drives the two fixed plates 22. Under the guidance of the limiting plate 23, the fixed plates 22 can drive the auxiliary wheel 24 to slide downward, so that the distance between the fixed plate 22 and the support leg 19 can be adjusted. One end of the fixed plate 22 is higher than the other end of the fixed plate 22, so that the entire device can be level, thereby reducing the force applied by the staff when tilting, and thus improving the comfort of the staff when working.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
