AI Technical Summary

Technical Problem

Existing roadbed construction tamping equipment relies on the impact force of a single free fall of the tamping hammer, resulting in low efficiency and requiring repeated tamping.

Method used

By using an impact plate in conjunction with a tamping disc, the impact plate is briefly raised and then lowered during the fall of the hammer, utilizing inertia and impact force to achieve multiple tamping blows from a single hammer drop. The impact plate can then be used to tamp the foundation a second or even multiple times.

Benefits of technology

It improves compaction efficiency, achieving the effect of multiple impacts with a single hammer drop, and significantly enhances the compaction effect and efficiency of the roadbed.

Abstract

This utility model relates to the field of tamping technology, specifically to a roadbed construction tamping and compaction device, which can effectively improve the tamping effect and tamping efficiency. It includes a tamping machine body, with only a mounting shaft inside the tamping machine body. A tamping hammer is slidably mounted on the mounting shaft. A tamping disc is provided at the bottom of the tamping machine body, and several vertically movable impact plates are provided at the top of the tamping disc. A guide shaft is fixedly provided on the tamping disc, guiding the vertical movement of the impact plates. The impact plates are slidably connected to the guide shaft. A connecting seat for connecting the tamping disc is provided at the bottom of the tamping machine body. A limiting block is installed at the top of the guide shaft. A through hole is opened on the tamping disc for the guide shaft to pass through. The diameter of the limiting block is larger than the diameter of the through hole. The limiting block is detachably connected to the guide shaft.
