Buffering equipment for hammering construction of concrete solid square pile
The invention relates to the field of pile hammers, and discloses a concrete solid square pile hammering construction buffering device which comprises an upper shell, a lower shell, a lower shell, a bottom cover, a bottom cover, a bottom cover, a bottom cover, a bottom cover, a bottom cover and a bottom cover, and is characterized in that the upper shell is fixedly mounted at the bottom of a pile hammering machine shell; the lower shell is located below the upper shell and fixedly connected with the square pile, the top face of the lower shell extends outwards to form a lower shell edge, and a buffering gap is formed between the lower shell and the upper shell in the non-impact state; the buffer assemblies are arranged between the shell edges of the upper shell and the lower shell; the buffer assembly comprises a lower cylinder; loading a cylinder; an inner push rod; a buffer spring I; an intermediate ring; and a buffer spring II. According to the pile hammering machine, the technical problem that in the prior art, the assembly tightness of the pile hammering machine is reduced due to the fact that instant pulling force caused when a pile body moves downwards at the moment of stress directly acts on the pile hammering machine is solved, the instant downward pulling force brought by the pile body to a machine shell of the pile hammering machine is buffered at the moment when the pile body impacts, and the service life of the pile hammering machine is prolonged.
本申请涉及打桩锤的领域，并公开了一种混凝土实心方桩锤击施工缓冲设备，包括：上壳体，固定安装于锤桩机机壳的底部，上壳体的底面向外延伸有上壳边；下壳体，位于上壳体的下方并与方桩固定连接，下壳体的顶面向外延伸有下壳边，在非撞击状态下的下壳体和上壳体之间具有缓冲间隙；缓冲组件，上壳体和下壳体的每个壳边之间均设置有缓冲组件；缓冲组件包括：下筒；上筒；内推杆；缓冲弹簧一；中间环；缓冲弹簧二。本申请解决了现有技术中桩体受力瞬间下移时带来的瞬间拉力会若直接作用在锤桩机上，导致锤桩机的组装松紧度降低的技术问题，实现了锤体撞击的瞬间，缓冲了桩体带给锤桩机机壳瞬间下拉力，提高了锤桩机的使用寿命。
