一种人字闸门顶枢拉架预应力锚杆张拉装置
本技术属于水利建筑工程领域,具体涉及一种人字闸门顶枢拉架预应力锚杆张拉装置。
技术介绍
目前,大型船闸每扇人字闸门顶枢通常各有2组顶枢拉架预应力锚杆组,每组均布置有6根锚杆,用于固定顶枢拉架,以保证人字闸门正常运转。然而大型船闸工程人字闸门进行安装时,没有专用于人字闸门顶枢拉架预应力锚杆张拉的装置,导致人字闸门顶枢拉架预应力锚杆张拉时面临着高难度、低质量、低效率的缺点,极大地制约了人字闸门顶枢安装效率。
技术实现思路
本技术目的在于:针对上述存在的问题,提供一种人字闸门顶枢拉架预应力锚杆张拉装置,该装置结构简单紧凑、安全可靠、便于施工,能够循环使用,适用于多种直径锚杆张拉,它能克服目前人字闸门顶枢拉架预应力锚杆张拉时面临的高难度、低效率、受力不均等缺点,能满足人字闸门顶枢安装的要求。本技术的技术方案是这样的:一种人字闸门顶枢拉架预应力锚杆张拉装置,包括顶枢拉架、预应力锚杆、张拉梁及张拉液压千斤顶;所述顶枢拉架放置在座板上,顶枢拉架与座板之间安装调节楔块,所述顶枢 ...
