一种便于校准的工程测绘三脚架
本技术涉及领域,具体涉及一种便于校准的工程测绘三脚架。
技术介绍
目前,在工程建设前期通常采用经纬仪、全站仪等测绘仪器进行各种定向、测距、测角、测高、测图以及摄影测量等方面的工作,而且测绘时都会使用测绘仪器三脚架,三脚架主要是用来支持和稳定三脚架上所安装的测绘仪。现有的测绘仪在测量前,需要进行垂直对中校准和水平校准,使仪器中心与地面测站点标志的中心在同一铅垂线上,并且使得测绘仪上处于水平状态,但是现有的三脚架在对中和调平的过程中,操作难度大,影响了测绘效率。
技术实现思路
针对现有技术的不足,本技术提供一种便于校准垂直度和水平度的工程测绘三脚架。本技术采用如下技术方案:一种便于校准的工程测绘三脚架,包括有安装测绘仪器的安装座,安装座上固定有水平仪,其特征在于:所述安装座底部固定有收纳箱,该收纳箱内固定有挡板,收纳箱于挡板上方转动连接有绕线轴,该绕线轴上缠绕有垂线,所述垂线穿过挡板中心的通孔连接有铅锤,绕线轴于收纳箱外还连接有把手;收纳箱侧面铰接有三根第一支架,该第一支架内可伸缩连接有第二支架,所述第二支架顶部和第一支架内侧固均固定有齿条,并且两齿条向互对应,两齿条之间还设有齿轮,该齿轮与两齿条同时啮合,齿轮中心还固定有转轴,转轴于第一支架外固定连接有旋钮。进一步,所述收纳箱内于挡板的下方设有放置铅锤的空腔,该空腔底部设有开口,收纳箱底部铰接有封闭此开口的门板。进一步,所述水平仪为气泡式水平仪,该水平仪表面设有三条分别对应三个第一支架的标线,三条标线交汇点位于水平仪中心。进一步,所述转轴于第一支架外的旋钮的另一侧螺旋连接有螺母。进一 ...
