Energy-saving rammer for highway construction

Abstract

The invention discloses an energy-saving rammer for highway construction. The rammer comprises a rammer body, handrails are symmetrically arranged at the top end of the rammer body, a first tamping plate is connected to the side, away from the handrails, of the rammer body through a supporting column, fixed supports are symmetrically arranged at one side of the first tamping plate and arranged on the rammer body, a rotating shaft is movably arranged between the fixed supports, a rolling wheel is movably arranged on the rotating shaft in a sleeving mode, a first channel is formed in each fixed support, fixed through holes are symmetrically formed in the two ends of each channel, fixed grooves are symmetrically formed in the two sides of the rotating shaft, and a first reset spring is arranged on the inner wall of each fixed groove. Accordingly, the structure is simple, the production cost is low, road surfaces of different widths can be rammed, resources are saved, the phenomenon that the rammer body cannot work conveniently is avoided, and meanwhile the phenomenon that when the rammer body works, the rolling wheel touches the ground is avoided, the labor is saved, the work efficiency is improved, and the use requirements of people are met.

Description

technical field [0001] The invention relates to the technical field of rammed earth machines, in particular to an energy-saving rammed earth machine for road construction. Background technique [0002] The ramming machine is a compaction machine that uses impact and impact vibration to ram the backfill soil layer by layer. It is divided into firepower rammer, frog type rammer and fast impact rammer, etc., and is made according to the principle of a two-stroke internal combustion engine. There are upper and lower pistons in the cylinder, the upper piston is an internal combustion piston, and the lower piston is a buffer piston. The lower part of the cylinder is equipped with a rammer with an inclined bottom surface, so that the vertical axis of the cylinder is deflected forward. The upper piston rod protrudes from the through hole in the middle of the cylinder top cover, the lower piston rod protrudes from the lower end of the cylinder, and is integrated with the tamper.

Problems solved by technology

However, most of the ramming plates of the existing ramming machines are of fixed length. When the width of the working place is too short, not only is the work inconvenient, but also the resources are wasted by starting the ramming machine at the same time. At the same time, the rollers of the existing ramming machines are mostly fixed installations. , when the roller is in use, the grounding of the roller will affect the normal operation of the ramming plate, which meets the needs of people
