我矿研制的ZZC-1型自照明觇标尺,经过多次试验,证明其性能良好,已成功地用于我矿井下测量。(一)ZZC-1型尺的设计与构造1.设计要求:该尺设计的主要特点是:(1)不用人立尺;(2)不用人照明;(3)不用人去纠正歪斜;(4)尺能绕纵轴旋转360°;(5)尺的重心在水平面上的投影,必须与测点的中心重合;(6)尺的体积和重量以轻便为原则。2.尺的结构如下图所示。
I mine developed ZZC-1 self-illumination 觇 scale, after many tests to prove its good performance, has been successfully used in mine measurement. (1) Design and construction of ZZC-1 type ruler 1.Design requirements: The main features of this ruler design are: (1) no need for people to stand upright; (2) no person lighting; (3) no person to correct skew; 4) The scale can be rotated 360 ° about the longitudinal axis; (5) The projection of the center of gravity of the scale on the horizontal plane must coincide with the center of the measuring point; (6) The size and weight of the scale should be light. 2. Ruler structure as shown below.
