Description

Technical Field

[0001] The utility model relates to the field of highway construction, in particular to a tamping machine for highway construction which is convenient for turning around. Background Art

[0002] When constructing a highway, the first thing to consider is the foundation. In order to increase the density of the foundation, it is usually necessary to use a tamping machine to repeatedly beat the foundation of the road to make the foundation more stable. In existing highway construction, frog-type tamping machines are often used to compact the foundation of the road. Frog-type tamping machines, also known as frog-type tamping machines, are compaction machines that use impact and impact vibration to compact backfill soil in layers. They are compaction machines with simple structures and easy operation. They are reliable, highly efficient, and easy to maintain, and are widely used in construction.

[0003] During construction, the frog-type compactor needs to reciprocate to compact the foundation of the road. Under the action of the pendulum, the frog-type compactor can move forward and adjust a small angle. For large frog-type compactors, due to their large size and weight, the frog-type compactor encounters greater resistance when turning around, making it inconvenient for workers to turn the frog-type compactor around, affecting construction efficiency.

[0032] When a U-turn is required, the motor 2 is turned off, and the armrest 16 is pressed downward to drive the third rotating shaft 17 to rotate. The third rotating shaft 17 drives the fourth rotating shaft 19 and the cam 20 to rotate through the first sprocket 30, the second sprocket 31 and the chain 32. During the rotation of the cam 20, the pressing plate 23 is squeezed, and the lifting column 22 and the lifting plate 21 are driven to move downward, so that the base plate 1 is suspended in the air, and the lifting plate 21 supports the ground, thereby reducing the resistance encountered by the compactor when turning around. Then, by rotating the armrest 16, the entire compactor is driven to rotate with the lifting column 22 and the lifting plate 21 as the fulcrum to achieve the purpose of turning around.
