Low-frequency and high-amplitude multi-functional table back compaction machine

Abstract

Disclosed is a low-frequency high-amplitude multifunctional platform back rammer compactor tool. A compaction base plate and a ramming impact kinetic energy force transfer block are fixedly connected through fixing bolts. The periphery of the compaction base plate and a tool side face shell are connected together through reinforcing connecting pieces. A piece of ramming iron makes contact with the ramming impact kinetic energy force transfer block through a buffer rubber backing plate. The buffer rubber backing plate is fixed to the top end of the ramming impact kinetic energy force transfer block. The ramming iron can move along a ramming iron limiting plate in the vertical direction. The ramming iron limiting plate is fixedly connected with the tool side face shell through limiting plate supporting pieces. The ramming impact kinetic energy force transfer block and the ramming iron form the body of the rammer compactor tool. A hydraulic jack is installed in the center inside the body of the rammer compactor tool. The bottom of the hydraulic jack and the upper surface of the compaction base plate are welded, sealed and fixed. A jack telescopic groove is formed in the protruding position of the hydraulic jack and the ramming iron. The hydraulic jack is filled with hydraulic oil inside the jack. The low-frequency high-amplitude multifunctional platform back rammer compactor tool is small in size, has the certain weight, and is fast to install and move and convenient to use.

Description

technical field [0001] The invention relates to a low-frequency and high-amplitude multifunctional table back tamping machine, which belongs to the construction field of tamping and filling construction in limited spaces in municipal, highway and bridge earthwork projects. Background technique [0002] In the current earth-rock compaction operations in municipal, highway, and bridge projects, there are still areas where earth-rock filling operations are performed in limited space or areas that cannot be compacted by large-scale earth-rock compaction construction machinery, such as backfilling of trenches, platform backs, etc. construction work etc. In the past backfill tamping operations, small pneumatic or electric tools were mainly used for tamping, and sand and gravel were tamped by water sinking. In these tamping operations, due to the small tamping work of the machine tool itself or the principle of natural settlement, the backfill material cannot be well tamped, coupl...

AI Technical Summary

Problems solved by technology

In these tamping operations, due to the small tamping work of the machine tool itself or the principle of natural settlement, the backfill material cannot be well tamped, coupled with the limited working space and human operation, the final tamping density cannot meet the specification requirements. Poor construction quality

Although there are currently machines on the market that use the principle of dynamic compaction to backfill and tamp the back of the abutment, the equipment is large in size and high in cost, and cannot meet the compaction requirements of trenches or abutment backfill under various limited space conditions.
