Abstract
The invention belongs to the technical field of construction, and relates to a jack hammer mechanism used in a tubular pile automatic production line die assembly machine. The jack hammer mechanism comprises jack hammers and jack hammer bases used for containing the jack hammers. Openings are formed in the upper end and the lower end of each jack hammer base. The jack hammers are inserted in the jack hammer bases. The bottoms of the jack hammers extend out of the jack hammer bases. Elastic mechanisms elastically connected with the jack hammers are arranged in the jack hammer bases. The jack hammers are pressed in the jack hammer bases through elastic force of the elastic mechanisms. When the external force is borne by the bottoms of the jack hammers and larger than the elastic force of the elastic mechanisms, the jack hammers can ascend along the axes of the jack hammer bases. When the external force disappears or the external force is smaller than the elastic force of the elastic mechanisms, the jack hammers can descend along the axes of the jack hammer bases. When one or several jack hammers meet resistance, normal work of the rest of the jack hammers is not hindered, and therefore it is ensued that the die assembly work is normally conducted, continuity of the die assembly work is ensured, and the die assembly efficiency is improved.
Description
Technical field
