Description

Technical Field

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

[0002] During road pavement construction, after placing the slag and other materials, the road surface needs to be compacted to ensure the stability of the roadbed. When compacting the road surface, large rollers are mostly used. However, in the narrow sections on both sides of the road surface, large equipment will not be able to compact, so a small compacting device is needed;

[0003] At present, the compaction device does not have the function of cleaning the hammer plate. As the hammer plate is continuously compacted, some mud will adhere to its bottom. When there is a red clay layer in the roadbed, mud adhesion is more likely to occur. With long-term compaction operation, the mud adhered to the bottom of the hammer plate may gradually increase. The hammer plate with mud continues to compact the ground, causing the ground to be uneven, thus affecting the compaction quality. Utility Model Content

[0028] Further, see Figure 3 As shown, a compacting assembly is provided inside the outer cover 2, and the compacting assembly includes a connecting column 4, a hammer plate 5, a hydraulic cylinder 6 and a hydraulic telescopic rod 7. The connecting column 4 is provided inside the outer cover 2, and the outer wall of the connecting column 4 is connected to a limit block, and a limit groove is provided outside the limit block and located on the inner wall of the outer cover 2, the hammer plate 5 is connected to the lower end surface of the connecting column 4 and is located inside the through groove 3, the hydraulic cylinder 6 is installed at the inner upper end of the outer cover 2, the hydraulic telescopic rod 7 is connected to the output end of the hydraulic cylinder 6, and the free end of the hydraulic telescopic rod 7 is connected to the connecting column 4;

[0029] Specifically, when in use, first hold and push the handrail 11, use the moving wheels to move the device to the required compaction area, then start the hydraulic cylinder 6 to drive the hydraulic telescopic rod 7 to extend and retract, so that the connecting column 4 rises and falls with the extension and retraction of the hydraulic telescopic rod 7, so that the connecting column 4 can drive the hammer plate 5 to repeatedly contact the ground, thereby compacting the ground.

[0030] The utility model provides Figure 4 A compacting device for road construction is shown, and a cleaning structure 8 is provided on the base 1.

[0032] Through the above technical solution:

[0033] When there is soil stuck on the bottom of the hammer disk 5, the forward and reverse motor 86 drives the threaded rod 87 to rotate, and the threaded rod 87 is threadedly matched with the threaded block 85, so that the threaded block 85 moves in the first groove 81. At the same time, the moving block 88 moves outside the connecting rod 89 in the second groove 82, and the connecting frame 83 equipped with the scraper 84 moves accordingly. During the movement, the scraper 84 can scrape off the soil stuck on the bottom of the hammer disk 5, so as to achieve the effect of cleaning the hammer disk 5, ensuring that there is no adhered soil on the bottom of the hammer disk 5 during the next tamping operation, avoiding the situation that the hammer disk 5 with soil sticking to it continues to tamp the foundation and easily causes uneven ground, ensuring the flatness of the foundation tamping and ensuring the tamping quality. In addition, the cleaning structure 8 is simple to operate and enhances the convenience of cleaning the hammer disk 5. In addition, according to the above-mentioned reverse driving of the threaded rod 87, the scraper 84 can be restored to its original position to facilitate the next cleaning operation of the hammer disk 5.

[0036] The fixed part includes a fixing groove 1011, a groove 1012, a fixing block 1013, a screw 1014 and an end block 1015. The fixing groove 1011 is opened on the upper end surface of the upper slider 105. The groove 1012 is opened on the inner wall of the base 1 and is located on one side of the slide groove 106.

This operation can quickly realize the connection between the small traction equipment and the tamping device, and the small traction equipment can be used to drive the tamping device to move without relying on human power to push it. This solves the problem that the tamping device is heavy due to human power pushing, resulting in a slow moving speed and affecting the tamping efficiency, thereby improving the tamping efficiency. In addition, when transporting the tamping device, the hook 104 can be connected to the transport vehicle body to prevent the tamping device from being displaced during transportation. The stability of transportation is guaranteed. In addition, after the hook 104 is pulled out, a tool is inserted into the slot of the end block 1015 and screwed, which drives the screw 1014 to rotate, so that the fixing block 1013 is lowered and inserted into the fixing slot 1011 provided in the slider 105, and the position of the pulled-out hook 104 can be fixed to avoid the situation where the hook 104 shrinks into the empty slot 101 during the traction movement, thereby ensuring the traction effect. When the connection is not needed, the screw 1014 is screwed in the opposite direction to move the fixing block 1013 out of the fixing slot 1011 and put it into the groove 1012 to release the fixation, and use the elastic force of the elastic plate 102 to drive the hook 104 into the empty slot 101 to prevent obstruction.
