Background

In geotechnical engineering monitoring projects, monitoring of deep horizontal displacement of a soil body is a very important detection index. As a common measuring instrument of the index, the inclinometer is widely applied to engineering monitoring projects such as foundation pits, side slopes, dams, reservoirs, tunnels and the like, and provides an important basis for the safety and stability analysis of engineering structures. In order to avoid complicated manual acquisition and adapt to severe and difficult-to-manually-monitored field environments, flexible inclinometers (or called array displacement meters) are produced in response to automatic monitoring of inclinometers. The monitoring of the deep displacement of an engineering structure by a flexible inclinometer is realized by monitoring an inclinometer pipe tightly connected with the structure, the inclinometer pipe is usually installed in a vertical drill hole penetrating through the earth surface to a rock stratum, and the flexible inclinometer observes the deformation of the inclinometer pipe through a probe, a control cable, a pulley device and data acquisition software. The principle of the flexible inclinometer is that the flexible inclinometer needs to roll into a guide rail of the inclinometer pipe through a pulley, the head part and the tail part of the flexible inclinometer are respectively provided with a pulley block, and the flexible inclinometer needs to be tightly pressed inside the inclinometer pipe. Therefore, the stable and practical elastic pulley block structure is very important. The pulley block is arranged before the flexible inclinometer is packaged, so that the packaging of the flexible inclinometer is inconvenient, the pulley block is better to install generally in field construction, and the pulley block is easy to damage in the transportation process, so that the detachable elastic pulley block structure plays a role. Meanwhile, when a rod needs to be lengthened or a pulley block of the flexible inclinometer needs to be maintained or replaced in the installation process of the flexible inclinometer, an elastic pulley block structure capable of being installed or detached at any time is urgently needed.

Based on the structure, the utility model designs a detachable elastic pulley block structure of a flexible inclinometer, so as to solve the problems.
