一种塔式起重机基础水平度调节装置
本技术涉及塔式起重机的
,尤其是一种塔式起重机基础水平度调节装置,特别涉及其机械连接结构。
技术介绍
塔式起重机基础的水平度是其安装、顶升和附着的最基本保证,且精度要求在在1/1000以内(允许值约0-2mm),基础水平度如果不符合要求,会导致设备无法安装,基础需要重新制作或者增加转换装置。现有技术的缺陷和不足:1.现场施工多采用钢筋加固,调节精度不够,容易超出基础水平度允许范围;2.由于基础自重的影响,可能会使基础底座下部的钢筋变形,产生沉降;3.由于采用钢筋加固需要现场测量尺寸和定位,工效较低。
技术实现思路
本技术的目的在于提供一种塔式起重机基础水平度调节装置,以解决塔吊基础制作过程中的水平度问题。克服了现有技术中存在的缺陷和不足。为了实现上述目的,本技术的技术方案为:一种塔式起重机基础水平度调节装置,所述水平度调节装置包括上下水平分布有的上锚板和下锚板,上锚板和下锚板之间垂直设有两片相互平行的筋板,筋板的上缘与上锚 ...
