前卡式预应力液压千斤顶尾端紧固件的结构优化

Optimization Design of the Fastening Pieces Design in the Fore-cramp Prestressing Hydraulic Jack

前卡式预应力液压千斤顶的尾端紧固件,目前一般由穿心拉杆固定螺母、穿心拉杆固定螺母端盖和堵头固定螺塞三个零件组成的结构设计方案。而这样的结构设计,增大了结构复杂程度,费工费时,使成本增加。如把尾端紧固件的结构做一定优化改进,将会降低装配难度、省时省工、减少成本,并使结构更为紧凑实用。

The fastening pieces are made of hold-down rod, which leads to more sophistication in the structure, improvement in the fastening parts will gives rise to lower cost-reducing, and more compact and practical structure. nut, end cap and plug more difficult processing, difficulties in assembling, screw in cross-core tie and higher costs. The time and labor-saving,
