Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a pile driver for municipal civil engineering. Background Art

[0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It refers to the materials, equipment, survey, design, construction, maintenance and repair, and other technical activities used, as well as the objects of engineering construction, that is, various engineering facilities built above ground, underground and on land, which directly or indirectly serve human life, production, military and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, and protective engineering, etc. In civil engineering construction, pile drivers are required. Pile drivers connect pile hammers with winches, so that the pile hammers fall freely on the top of the piles during pile driving, and the piles are driven into the ground by the impact force of the pile hammers.

[0003] However, the existing pile driver is not convenient for adjusting the drop height of the pile hammer, so the pile driving force is not convenient for changing.
