Description

Technical Field

[0001] This utility model relates to the field of road paving machine technology, and more specifically, to a road paving edge plate vibration device and a paver. Background Technology

[0002] Road pavers are the core equipment for paving asphalt, concrete, and other pavement materials in road construction. The screed, as a key component of the paver, directly affects the smoothness and finishing effect of the paved surface; its performance adaptability is crucial to construction quality. With the rapid development of road construction, the demand for ultra-thick paving in scenarios such as high-grade highways and heavy-duty roads is becoming increasingly prominent. Ultra-thick pavers have emerged and are widely used in various engineering projects, meeting the construction requirements for pavements of different thicknesses. In conventional paving operations, the paver uses the screed to level and initially compact the paving material, laying the foundation for subsequent pavement shaping.

[0003] However, traditional ultra-thickness pavers still have significant technical shortcomings in actual operation: when the paved road surface reaches the designed thickness, the ends of the formed road surface along the width direction lack dedicated compaction mechanisms and effective protective measures, resulting in insufficient compaction at the road ends. This problem directly leads to loose road ends and insufficient structural stability, and in severe cases, collapses may occur. This not only significantly reduces the quality and service life of the road surface but may also increase later maintenance costs and affect road traffic safety. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to solve the problem of compaction at both ends of the road surface in ultra-thick paving operations, prevent the ends from loosening and collapsing, and improve the overall quality of the road surface.

[0005] This utility model provides a road paving edge plate vibration device, including a side tamping plate, a driving mechanism and a high-frequency vibrator. The driving mechanism and the high-frequency vibrator are respectively connected to the same surface of the side tamping plate. The driving mechanism is driven to drive the high-frequency vibrator to generate vibration. One end of the side tamping plate is hinged to the side end of the paver, and the other end is used to contact the road surface.

[0024] like Figures 1 to 3 As shown in the figure, this utility model embodiment provides a road paving edge plate vibration device, including a side tamping plate 10, a driving mechanism 20 and a high-frequency vibrator 30. The driving mechanism 20 and the high-frequency vibrator 30 are respectively connected to the same surface of the side tamping plate 10. The driving mechanism 20 is driven to drive the high-frequency vibrator 30 to generate vibration. One end of the side tamping plate 10 is hinged to the side end of the paver, and the other end is used to contact the road surface.

[0025] Specifically, the sides of a paver refer to the two ends perpendicular to the direction of paver movement, or in other words, the ends of the paver corresponding to the two ends in the width direction of the road surface, such as... Figure 3 and Figure 4As shown in the figure, the Y-axis of the XYZ coordinate system represents the direction of movement of the paver, and the X-axis represents the width direction of the paver and the road surface. Similarly, the side baffles 01 of the paver mentioned later refer to the baffles at both ends perpendicular to the direction of movement of the paver. The side tamping plate 10 is made of high-strength wear-resistant steel plate to ensure structural stability and service life during the compaction process and to avoid deformation or damage caused by long-term high-frequency vibration. The drive mechanism 20 and the high-frequency vibrator 30 are connected mechanically (such as by a coupling) to achieve power transmission, ensuring efficient power transmission. The high-frequency vibrator 30 has an eccentric rotating mass block inside. Its working principle is as follows: when the driven mechanism 20 drives it to rotate at high speed, the eccentric block generates periodic centrifugal force, thereby causing the shell of the high-frequency vibrator 30 to generate high-frequency simple harmonic vibration, and transmitting the vibration to the side tamping plate 10. One end of the side tamping plate 10 is hinged to the paver, and the high-frequency simple harmonic vibration generated by the high-frequency vibrator 30 can act on the road surface through the other end of the side tamping plate 10. The hinged position of the side tamping plate 10 is adapted to the installation space on the side of the paver, and will not interfere with the operation of the paver's original screed, ensuring the smoothness of the overall construction process.

[0026] In this embodiment, the road paving edge plate vibration device provided can be applied to a paver in road construction. By hinged to the side of the paver, the device can carry out paving operations synchronously with the paver, ensuring the continuity of compaction and paving operations at both ends of the road along the width direction. Furthermore, by connecting the drive mechanism 20 and the high-frequency vibrator 30 to the same surface of the side plate 10, the drive mechanism 20 drives the high-frequency vibrator 30 to generate high-frequency vibration. The vibration energy can be directly and efficiently transmitted to the side plate 10, enabling the side plate 10 to apply a continuous and uniform compaction force to both ends of the road. This specifically solves the problem of insufficient compaction caused by the lack of a dedicated compaction mechanism at the ends of ultra-thick paved roads, effectively preventing the road ends from loosening and collapsing, improving the overall forming quality and structural stability of the road, and extending the service life of the road.

[0027] Optionally, such as Figures 1 to 4 As shown, the road paving edge plate vibration device also includes a pin shaft 40, and the end of the side tamping plate 10 is provided with a hinge plate 11. The hinge plate 11 has a hinge hole that matches the pin shaft 40. The side tamping plate 10 is hinged to the bottom end of the side baffle 01 of the paver through the pin shaft 40 and the hinge hole.

[0028] Specifically, the hinge plate 11 can be welded to the end of the side ramming plate 10, and the pin 40 passes through the hinge hole on the hinge plate 11 and the corresponding mounting hole on the paver side baffle 01 to form a rotatable connection.

[0029] In this embodiment, the side tamping plate 10 can be quickly and reliably installed onto the paver side baffle 01 by the cooperation of the pin 40 and the hinge plate 11, forming a stable hinge support. Furthermore, this hinge structure ensures that the side tamping plate 10 can transmit stable vibration force to the end of the road surface during operation, and also allows the entire device to be easily disassembled in non-operational states (such as during site relocation), greatly improving the flexibility and convenience of equipment use.

[0030] Optionally, such as Figures 1 to 4 As shown, the road paving edge plate vibration device also includes a housing 50, which is connected to the edge compaction plate 10 and covers the outside of the drive mechanism 20 and the high-frequency vibrator 30.

[0031] Specifically, the housing 50 is fixed to the side ramming plate 10 by means of bolts or welding, and its internal space is sufficient to accommodate the drive mechanism 20 and the high-frequency vibrator 30.

[0032] In this embodiment, by providing a housing 50 covering the drive mechanism 20 and the high-frequency vibrator 30, these precision components are effectively isolated from dust, moisture and splashed asphalt in the external construction environment; thereby, the risk of component failure due to contamination or corrosion is significantly reduced, the service life of the device is extended, and the overall appearance and safety of the machine are improved.

[0033] Optionally, such as Figures 1 to 3 As shown, the road paving edge plate vibration device also includes a roller mechanism 60, which is connected to the side tamping plate 10 and is located on the same side of the side tamping plate 10 as the driving mechanism 20.

[0034] Specifically, the roller mechanism 60 allows the entire road paving edge plate vibratory device to move on the road surface, facilitating the transfer of the entire road paving edge plate vibratory device. The roller mechanism 60 is symmetrically arranged on both sides of the housing 50 to ensure force balance during device transfer and avoid unilateral tilting. The installation height of the roller mechanism 60 is adjustable. For example, by adjusting the length of the support leg 61, the roller 62 can be in full contact with the ground during transfer, and the roller 62 can be removed from the ground during operation without affecting the compaction effect. The installation position of the roller mechanism 60 avoids the vibration transmission path of the drive mechanism 20, preventing the transfer structure from interfering with the stability of the operation.

[0035] In this embodiment, by setting a roller mechanism 60 on the side tamping plate 10, this heavy device integrating drive and vibration components can be easily moved and transported after disassembly; thereby, the practical problem of difficult handling of heavy auxiliary devices is solved, the labor intensity of operators is reduced, and the efficiency of construction logistics is improved.

[0036] Optionally, such as Figures 1 to 3As shown, the roller mechanism 60 includes a support leg 61 and a roller 62. The roller 62 is rotatably connected to one end of the support leg 61, and the other end of the support leg 61 is connected to the side of the housing 50.

[0037] Specifically, the support leg 61 can be a section of steel or steel pipe, one end of which is connected to the side plate of the housing 50 by bolts, and the other end is rotatably connected to the roller 62 by bearings or bushings.

[0038] In this embodiment, by adopting a roller mechanism 60 that combines the support leg 61 and the roller 62 separately, the height of the roller 62 off the ground and its lateral position can be flexibly adjusted as needed. Thus, the stability of the device during movement is ensured, and the support leg 61 can also be used as a reinforcing rib to enhance the local strength of the side plate of the box 50, achieving a multi-purpose effect.

[0039] Optionally, such as Figures 1 to 4 As shown, the box body 50 includes side panels and a cover plate. The four side panels are sequentially spliced ​​together and connected to the side plate 10. The cover plate is placed on the top of the four side panels and is hinged to one of the side panels.

[0040] Specifically, the side panels and cover plate of the housing 50 together form a protective space that is enclosed at the top and sides and connected to the side ramming plate 10 at the bottom. The hinged cover plate facilitates routine inspection and maintenance of internal components. It should be noted that... Figure 1 and attached Figure 2 The diagram only schematically shows the side panels of box 50, and does not depict the entire structure of box 50.

[0041] In this embodiment, the housing 50 is constructed by combining side plates and hinged cover plates, which simplifies the manufacturing process of the housing 50 and reduces costs. Furthermore, the hinged cover plate design greatly facilitates daily inspection and maintenance of the drive mechanism 20 and the high-frequency vibrator 30, eliminating the need to disassemble the entire housing 50 and saving maintenance time and costs.

[0042] Optionally, such as Figure 1 and Figure 2 As shown, multiple studs are welded onto the side ramming plate 10, and the multiple studs are respectively connected to the drive mechanism 20 and the housing 50.

[0043] Specifically, the studs are pre-welded vertically to the side plate 10. During installation, these studs are inserted into the mounting holes at the bottom of the drive mechanism 20 and the housing 50, and then tightened from above with nuts.

[0044] In this embodiment, by welding multiple studs onto the side ramming plate 10, the drive mechanism 20 and the housing 50 can be securely clamped together from above using nuts. This connection method avoids drilling and tapping on the side ramming plate 10, ensuring the integrity of its structural strength. It is particularly suitable for working conditions subject to vibration loads, and the connection is reliable and has good vibration resistance.

[0045] Optionally, such as Figure 1 and Figure 2 As shown, a support base 12 is provided on the side ramming plate 10, and the high-frequency vibrator 30 is connected to the support base 12.

[0046] Specifically, the support base 12 is an independent casting or welded part, which is fixed to the side ramming plate 10 by bolts or welding, and the high-frequency vibrator 30 is fixed to the support base 12 by bolts.

[0047] In this embodiment, the high-frequency vibrator 30 is installed by setting an independent support seat 12 on the side tamping plate 10, which adds a rigid transition structure between the high-frequency vibrator 30 and the side tamping plate 10. Furthermore, this structure can better distribute and bear the huge alternating stress generated by the high-frequency vibrator 30, prevent stress concentration from acting directly on the side tamping plate 10 body, and effectively improve the rigidity and durability of the entire device.

[0048] Optionally, such as Figure 1 and Figure 2 As shown, the drive mechanism 20 includes a continuously variable hydraulic motor, which is driven and connected to the high-frequency vibrator 30, and is used to connect to the hydraulic system of the paver.

[0049] Specifically, the continuously variable hydraulic motor is connected to the hydraulic system of the paver body through a high-pressure oil pipe, and its speed is adjusted by the paver's hydraulic control system.

[0050] In this embodiment, by using a continuously variable hydraulic motor as the drive mechanism 20, the operator can smoothly and precisely adjust the vibration frequency of the high-frequency vibrator 30 during operation according to different paving materials (such as asphalt and concrete) and paving thickness. This enables precise control of the compaction process parameters at the road edge, ensuring optimal compaction results under different working conditions, improving the adaptability and controllability of construction quality. Furthermore, by connecting to the hydraulic system of the paver, it provides a convenient power source, making it easy and efficient to use.

[0051] In addition, another embodiment of the present invention provides a paver, including the above-mentioned road paving edge plate vibration device.

[0052] For example, the paver is an ultra-thick road paver, and may also include a hydraulic control module adapted to the road paving edge plate vibration device for precisely adjusting the speed of the continuously variable hydraulic motor.

[0053] In this embodiment, the paver provided by this embodiment, by incorporating the aforementioned road paving edge plate vibration device, achieves technical effects largely the same as those of the aforementioned road paving edge plate vibration device, and will not be elaborated further here. Simultaneously, by linking the device with the paver's hydraulic system and control system, the degree of automation and construction efficiency are further improved.

[0054] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
