Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering machinery, in particular to a paver. BACKGROUND

[0002] At present, when laying a road, a paver and a vibrating road roller are two commonly used mechanical devices. The paver is mainly used for paving various materials on the base and surface layer of a highway, and the working device of the vibrating road roller is a steel wheel which provides exciting force for the steel wheel through an exciter to achieve a compaction effect.

[0003] To improve work efficiency, pavers with large width and thickness are increasingly used. Such pavers can effectively increase the paving width and layer thickness, reduce three-layer paving to two-layer paving, and reduce two passes of paving to one pass, thereby greatly improving construction efficiency. When performing large-width and large-thickness paving work, a formwork is usually used to limit the paving range. First, a formwork is prefabricated, usually a wooden formwork or a concrete formwork, then the formwork is erected at a preset position, and finally paving is performed. After paving is completed, the paving material needs to be compacted.

[0004] For a paver with large width and thickness, a large-tonnage vibrating road roller needs to be used for work compaction. The large-tonnage vibrating road roller has a relatively large tonnage, and it is difficult to achieve edge compaction. If forced edge work is performed, the formwork may be damaged, causing economic losses, and a slope may be formed due to collapse, affecting the quality of subsequent construction.

[0005] Therefore, a large-tonnage vibrating road roller can be used to compact the middle part, and then a small compaction mechanical device or manual work is used to compact the edge. This method needs to additionally purchase a small compaction mechanical device, which requires additional cost. Moreover, the paver, the large-tonnage vibrating road roller, and the small compaction mechanical device work independently, and the operator needs to move back and forth to operate different devices, which has low automation and low work efficiency.

[0006] It should be noted that the information disclosed in the background section of the present application is only intended to increase the understanding of the overall background of the present application and should not be regarded as acknowledging or implying in any form that the information constitutes prior art known to those skilled in the art.

[0043] As shown in Figure 1 and Figure 2 In an embodiment of the paver provided by the present application, the paver comprises a paving main machine 100, a connecting device 200 and a vibrating device 300, the paving main machine 100 is used to pave the material on the road surface, the vibrating device 300 is connected to the rear side of the paving main machine 100 through the connecting device 200, and the vibrating device 300 is used to compact the two side edges of the road surface.

[0044] In the above embodiment, by connecting the vibrating device 300 to the rear side of the paving main machine 100, the two side edges of the completed paving road surface can be compacted by the vibrating device 300 at the same time of paving, and the work efficiency is high; the paving main machine 100 and the vibrating device 300 are connected through the connecting device 200, which are not two independent devices, so that it is not necessary to move back and forth between the two devices to switch, further improving the work efficiency; at the same time, the vibrating device can compact the two side edges of the road surface, solving the problem of high difficulty in edge compaction when using a large-tonnage vibrating road roller for compaction, improving the edge compaction effect and improving the quality of the paved road surface.

[0045] The paver further comprises a power system, which simultaneously provides power for the paving main machine 100 and the vibrating device 300. The paving main machine 100 and the vibrating device 300 adopt the same power system, which can save power configuration, save cost and save layout space.

[0046] As shown in Figure 3 The paver further comprises a connecting pipeline 401 and a hydraulic motor 402, and the power system comprises an oil tank and a hydraulic pump, both of which are arranged on the paving main machine 100, the hydraulic pump is connected with the hydraulic motor 402 through the connecting pipeline 401, and the hydraulic motor 402 drives the vibrating device 300 to vibrate.

[0047] The hydraulic pump takes oil from the oil tank to supply the hydraulic motor 402, and the hydraulic motor 402 transmits power to the vibrating device 300 after rotating, and the vibrating device 300 realizes compaction of the road surface through vibration after obtaining power.

[0048] The oil inlet of the hydraulic motor 402 is provided with a hydraulic connector 403 for connecting the oil inlet and the connecting pipeline 401. The hydraulic connector 403 can be a quick release connector for convenient connection and disconnection. The two connecting pipelines 401 are provided with a pipe clamp 404 for fixing the connecting pipelines 401, so as to prevent the connecting pipelines 401 from being entangled with each other and ensure smooth flow of hydraulic oil.

[0049] The paving main machine 100 can include a walking system, a hydraulic system and a conveying and distributing system. The hydraulic system obtains power through a hydraulic pump and transmits the power to the walking system to drive the paving main machine 100 to walk or turn. The power of the hydraulic system can also be transmitted to the conveying and distributing system, and the conveying and distributing system outputs various materials to complete the paving work.

[0050] In some embodiments, the connecting device 200 is rotatably connected with the vibrating device 300, so that the vibrating device 300 can swing left and right relative to the paving main machine 100. Here, “left and right” is based on the advancing direction of the paver during paving, and the advancing direction of the paver is forward, the reverse direction is backward, and the two sides are left and right.

[0051] The vibrating device 300 is arranged to be able to swing left and right relative to the paving main machine 100, so that the vibrating device 300 and the paving main machine 100 can rotate relative to each other when the paver is walking, reducing the radius when the paver turns and improving the flexibility of the paver.

[0052] The connecting device 200 can be configured to enable the vibrating device 300 to float up and down relative to the paving main machine 100. The advantage of this arrangement is that the vibrating device 300 can adapt to different road paving thicknesses, improving the application range of the paver; at the same time, during the vibration process, the vibrating device 300 floats up and down relative to the paving main machine 100, which can reduce the vibration force transmitted to the paving main machine 100, improve the working stability of the paver, and also reduce the damage to the components caused by vibration, thereby improving the service life of the components.

[0053] The height of the vibrating device 300 relative to the paving main machine 100 in the vertical direction is adjustable. This arrangement can first adjust the relative height of the vibrating device 300 and the paving main machine 100 to a suitable position according to the actual working environment before work, and then relatively fix the adjustment position. The position of the vibrating device 300 relative to the paving main machine 100 floating up and down is two different positions, which can respectively play the functions of preliminary adjustment and self-adaptive adjustment during work.

By inserting the first connecting member into the first mounting holes at different heights, the connection of the first connecting rod 201 at different positions of the third connecting rod 203 is realized to adjust the relative height between the vibrating device 300 connected with the first connecting rod 201 and the paving host 100.
