Abstract

本实用新型提供一种简易丈量卡尺,在测量横臂的底部两端分别设有测量脚锥,测量杆固定在测量横臂的中部,手柄装置在测量杆的顶部。本实用新型的积极效果在于:丈量卡尺结构简单,成本低廉,容易操作,携带方便;一人即可完成丈量工作,使水准测量中前后视距在规范允许范围之内。

Description

简易丈量卡尺
技术领域
本实用新型提供一种简易丈量卡尺,应用于等级水准测量,属于工程控制测量领域。
背景技术
控制测量中的等级水准测量为了消除仪器倾角误差,使前后视距相等为提高工作效率需提前丈量好前后视距使其在规范允许之内。
以往的测量是由两个人使用测绳或钢尺完成视距丈量,在地上来回拖动测绳或钢尺,不但费时费力,工作效率也非常低,误差大,影响了工程进度和质量,测绳或钢尺的磨损也非常大。
发明内容
本实用新型提供一种简易丈量卡尺,解决了以往人工使用测绳或钢尺完成视距丈量存在的工作效率低,误差大等缺欠。
本实用新型公开的简易丈量卡尺的技术解决方案如下:
在测量横臂的底部两端分别设有测量脚锥,测量杆固定在测量横臂的中部,手柄装置在测量杆的顶部。
使用本实用新型测量时,将测量横臂底部的一端测量脚锥对准起始测量点,手握手柄捻转测量横臂交替移动测量脚锥,即可实现视距的丈量。
本实用新型的积极效果在于:丈量卡尺结构简单,成本低廉,容易操作,各个部件可拆卸,携带方便;一人即可完成丈量工作,使水准测量中前后视距在规范允许范围之内。
附图说明
图1为本实用新型结构原理图;
其中,1、测量脚锥;2、测量横臂;3、测量杆;4、手柄。
具体实施方式
根据图1所示,测量横臂2的底部两端分别设有可拆卸的测量脚锥1,测量杆3的两端分别为螺纹结构,其底部与测量横臂2中部的螺孔构成固定连接;测量杆3的上部与手柄4底部的螺孔构成固定连接。
