岩层位移监测仪位移测线收紧机构
摘要：
一种岩层位移监测仪位移测线收紧机构，包括支承台、转轴、收线轮，所述支承台安装在岩层位移监测仪壳体下侧，所述转轴固定在所述支承台上，所述转轴两侧安装所述收线轮，其中：所述收线轮外侧的所述转轴上套有摩擦轮；所述摩擦轮连接有张紧装置。本实用新型岩层位移监测仪位移测线收紧机构不限制岩层位移监测仪量程且位移测量拉线的收紧力恒定。
摘要（英）：

A displacement measuring line tensioning mechanism of a rock stratum displacement monitor comprises a supporting table, a rotating shaft and take-up reels. The supporting table is arranged on the lower side of a casing of the rock stratum displacement monitor, the rotating shaft is fixed on the supporting tale, two sides of the rotating shaft are equipped with the take-up reels, wherein friction wheels are sleeved on the outer sides of the take-up reels on the rotating shaft, and the friction wheels are connected with a tension device. The displacement measuring line tensioning mechanism of arock stratum displacement monitor does not limit measuring range of the rock stratum displacement monitor, and tension force of the measuring line is constant.
