DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5As shown, a roadbed compaction device for road and bridge construction includes a cart 1, a bracket 2 is installed on the upper end of the cart 1, a compaction cylinder 3 is installed on the upper end of the bracket 2, a fixed frame 4 is installed on the lower end of the compaction cylinder 3, a compaction plate 5 is provided at the lower end of the fixed frame 4, a noise reduction structure 6 is provided at the upper end of the compaction plate 5, the noise reduction structure 6 includes four movable rods 7, the upper ends of the four movable rods 7 are located on the upper end of the fixed frame 4 and slide, the outer walls of the four movable rods 7 are sleeved with springs 8, a mounting plate 9 is installed in the middle of the upper inner wall of the fixed frame 4, and an airbag 10 is fixedly provided at the lower end of the mounting plate 9.

[0024] In this embodiment, a cleaning structure 11 is installed at the rear end of the cart 1, and the cleaning structure 11 includes a screw rod 12. The outer wall of the screw rod 12 is sleeved with a slider 13, and the lower end of the slider 13 is provided with a cleaning plate 14. A stabilizing groove 15 is opened at the rear end of the cart 1, and the cleaning plate 14 is located inside the stabilizing groove 15.

[0025] The screw rod 12 is used to drive the slider 13 to move, and the slider 13 is used to drive the cleaning plate 14 located at the lower end of the compacting plate 5 to move and clean, and the stabilizing groove 15 facilitates the stabilization of the movement of the cleaning plate 14.

[0026] In this embodiment, a corner of one side of the upper end of the cleaning plate 14 close to the pressing plate 5 is arc-shaped, and a corner of one side of the lower end of the pressing plate 5 is arc-shaped.

[0027] The corner of the upper end of the cleaning plate 14 close to the compacting plate 5 is arc-shaped, which, together with the arc-shaped corner of the lower end of the compacting plate 5, can ensure that the cleaning plate 14 can stably scrape the lower end of the compacting plate 5.

[0028] In this embodiment, a limit block is fixedly provided at the rear end of the cart 1 , and the limit block is located at the front end of the screw rod 12 .

[0029] The limiting block limits the sliding block 13 to prevent the cleaning plate 14 from moving to one side of the compacting plate 5 .

[0030] In this embodiment, moving wheels are installed on the front and rear sides of the lower end of the cart 1.

[0031] The moving wheels make it easy for the operator to push the trailer to achieve compaction at different locations of the roadbed.

[0032] In this embodiment, a push rod is installed on one side of the upper end of the cart 1.

[0033] In this embodiment, a handle is fixedly mounted on one side of the screw rod 12 .

[0034] The handle facilitates the operator to rotate the screw rod 12.

[0035] It should be noted that the utility model is a roadbed compacting device for road and bridge construction. When in use, the compacting cylinder 3 is started, so that the fixed frame 4 moves downward, thereby driving the lower end of the compacting plate 5 to contact the road surface. When the compacting plate 5 is subjected to pressure, it will squeeze the spring 8. After the spring 8 is buffered, the buffer between the compacting plate 5 and the foundation can be reduced. When the compacting plate 5 continues to move upward, it contacts the airbag 10, which can better buffer and reduce noise pollution.

[0036] When mud adheres to the lower end of the compacting plate 5, the handle is turned to rotate the screw rod 12, thereby moving the slider 13, and the slider 13 drives the cleaning plate 14 to slide inside the stabilizing groove 15, so that the cleaning plate 14 is located at the lower end of the compacting plate 5 and scrapes off the adhered mud to achieve cleaning, thereby ensuring that the lower end of the compacting plate 5 is more stable next time.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
