一种便携式矿用锚杆测力计

Abstract

本实用新型涉及矿用锚杆测力计相关技术领域，具体是一种便携式矿用锚杆测力计，包括测量缸筒、集线盒和观测线以及测力计组件，所述测量缸筒外部的固定处安装有集线盒，所述集线盒上的螺纹紧固处设置有观测线，所述测力计组件上的安装处设置有测量缸筒和集线盒，在本实用新型中，矿用锚杆测力计通过螺纹锁扣环和中心孔进行锚杆安装时，固定套和锚杆适配与螺纹锁扣环和中心孔采用相同结构，针对粗细不同的锚杆进行定位安装，固定套和锚杆适配可代替矿用锚杆测力计配备的垫圈，固定套和锚杆适配避免垫圈大小不平整造成测力计与锚杆轴线同轴偏差，固定套和锚杆适配轴线同轴安装在测量缸筒内部预防出现偏心受力。
