Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to a road paving and compacting device. Background Art

[0002] Road paving and compaction are necessary steps to build a high-quality road. After the base layer of the road is paved, it needs to be compacted. The purpose of compaction is to eliminate gaps and increase the density of the road surface, thereby enhancing its durability and bearing capacity.

[0003] The existing road paving and compaction method is to pour asphalt concrete into the road location and then use a roller to compact it to ensure that the road surface is flat and solid. However, due to the unevenness of the road or other factors during the rolling process, it is difficult for the roller to drive in a straight line, resulting in uneven road compaction and insufficient road surface flatness, which affects the road paving quality.

[0004] Therefore, a road paving and compacting device has been developed that can guide the roller when compacting the road, keep the road compacted along a straight line, and improve the road compaction quality. Utility Model Content

[0005] In order to overcome the shortcomings of existing road paving and compaction, in which it is difficult for rollers to travel in a straight line, resulting in uneven road compaction effect, insufficient road surface flatness and affecting the road paving quality, the utility model provides a road paving and compacting device that can guide the roller when compacting the road, keep the road compacted in a straight line and improve the road compaction quality.

[0006] A road paving compaction device includes a material rack, a roller, a wheel valve, a side pin, a support frame and a side ruler mechanism. The lower part of the material rack is rotatably connected to the roller, the front and rear parts of the material rack are rotatably connected to the wheel valve, the wheel valves are provided with material discharge troughs, the front and rear sides of the material rack are connected to side pins, the support frame is rotatably connected between the side pins, and the material rack is provided with a side ruler mechanism that can prevent the roller from deflecting.

[0007] Further description: a clamping hole is provided on the support frame.

[0008] Further description, it also includes a handle, and the left and right sides of the wheel valve are connected with a handle.

[0009] To further explain, the side ruler mechanism includes a main arm, a staple, a telescopic joint and an outer ruler. The main arms are connected to the front and rear sides of the lower part of the material rack. An outer ruler is provided on the side of the main arms that are away from each other. The outer ruler is slidably connected to the adjacent main arm through a telescopic joint. The telescopic joint is clamped with a staple to the connected main arm, and the telescopic joint is clamped with a staple to the connected outer ruler.

[0010] Further explanation: a ball bearing is provided on the outer ruler.

[0011] Further description, it also includes a front ruler mechanism, which includes a front seat, a torsion spring and a rake ruler. The front seat is connected to the front side of the lower part of the material rack, and the rake ruler is rotatably connected to the front seat. Two left and right torsion springs are connected between the rake ruler and the front seat.

[0012] The beneficial effects are as follows: 1. The utility model enables the nails to be separated from the main arm and the outer ruler, and when the telescopic joint is slid to a specified length, the outer ruler is adjusted to contact the roadbed of the road, thereby achieving the effect of guiding the roller when compacting the road, maintaining the road compaction in a straight line, and improving the road compaction quality.

[0013] 2. The utility model moves the material rack to drive the harrow to move when paving the road. Under the action of the torsion spring, the harrow is pressed against the road surface, so that the harrow removes and collects the debris in front of the paving, thereby achieving the effect of removing the debris on the road surface and facilitating the paving of the road.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] A road paving compaction device, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, it includes a material rack 1, a roller 2, a wheel valve 3, a handle 4, a side pin 5, a support frame 6 and a side ruler mechanism 7. The lower part of the material rack 1 is rotatably connected to the roller 2, the front and rear parts of the material rack 1 are rotatably connected to the wheel valve 3, the wheel valve 3 is provided with a material discharge chute, the left and right sides of the wheel valve 3 are connected to the handle 4, the front and rear sides of the material rack 1 are connected to the side pins 5, the support frame 6 is rotatably connected between the side pins 5, the support frame 6 is provided with a snap-in hole for easy splicing, and the material rack 1 is provided with a side ruler mechanism 7 that can prevent the roller 2 from deflecting.

[0022] like Figure 1 and Figure 4 As shown, the side ruler mechanism 7 includes a main arm 71, a staple 72, a telescopic joint 73 and an outer ruler 74. The main arms 71 are connected to the front and rear sides of the lower part of the material rack 1. An outer ruler 74 is provided on the side of the main arms 71 away from each other. The outer ruler 74 is provided with a ball bearing to facilitate movement when in contact with the roadbed. The outer ruler 74 is slidably connected to the adjacent main arms 71 by a telescopic joint 73. The telescopic joint 73 is clamped with a staple 72 to the connected main arm 71, and the telescopic joint 73 is clamped with a staple 72 to the connected outer ruler 74.

[0023] When using the utility model, first move the material rack 1 to the road paving area, then adjust the support frame 6 to rotate on the side pin 5, and snap it with the snap-in hole on the support frame 6 on another material rack 1, so that multiple material racks 1 can be spliced. After the splicing of the material racks 1 is completed, the support frame 6 is snapped onto the engineering vehicle to facilitate the movement of the material rack 1. Then, pour the asphalt concrete into the material rack 1, and then turn the wheel valve 3 by the handle 4 to open it, so that the asphalt concrete falls from the discharge chute on the wheel valve 3 onto the road, and at the same time push the material rack 1 to move, so that the asphalt concrete is evenly distributed. It is paved on the road. After the asphalt concrete is paved, the wheel valve 3 is turned to close, and the pin 72 is disengaged from the main arm 71 and the outer ruler 74. When the telescopic joint 73 is slid to the specified length, the outer ruler 74 is adjusted to contact the roadbed of the road. Then, the pin 72 is re-engaged with the main arm 71 and the outer ruler 74 to fix the outer ruler 74. This plays a role in guiding the roller 2 when compacting the road, keeping the road compacted in a straight line, and improving the compaction quality of the road. Then, the material rack 1 is moved to drive the roller 2 to move and compact the road.

[0024] like Figure 1 and Figure 4 As shown, it also includes a front ruler mechanism 8, which includes a front seat 81, a torsion spring 82 and a rake ruler 83. The front seat 81 is connected to the front side of the lower part of the material rack 1, and the rake ruler 83 is rotatably connected to the front seat 81. Two left and right torsion springs 82 are connected between the rake ruler 83 and the front seat 81.

[0025] The front ruler mechanism 8 of the device can be used to remove debris on the road. When paving the road, the material rack 1 moves, driving the rake ruler 83 to move. Under the action of the torsion spring 82, the rake ruler 83 is pressed against the road surface, so that the rake ruler 83 removes and collects the debris in front of the paving, thereby removing the debris on the road surface and facilitating the paving of the road.
