Hollow inclusion strain gauge mounting device and method

The invention provides a hollow inclusion strain gauge mounting device. The device comprises a balancer and a mounting rod inserted into the balancer, the balancer comprises a support ring and supportrods distributed along in the circumferential direction of the support ring. The balancer guarantees that the whole device is in a straight state in a drilled hole by supporting the gravity center ofthe whole device, so that the compression resistance and the deformation resistance of the mounting rod are enhanced, the mounting rod is prevented from being extruded by a hole wall and bent under the action of gravity when extending into the drilled hole, and the defect in the prior art that the mounting rod is prone to deformation under the condition that the drilled hole is too long so that the hollow inclusion strain gauge cannot accurately enter the small measuring hole is overcome. 本发明提供了一种空心包体应变计安装装置，包括平衡器和插装在平衡器内的安装杆，平衡器包括支撑环和沿支撑环圆周方向分布的支撑杆。平衡器通过支撑整个装置的重心，保证整个装置在钻孔之中呈平直状态，从而增强了安装杆的抗压和抗变形能力，避免安装杆在伸入钻孔时，受到孔壁的挤压
