An automatic rotating device for inclinometer tube

Abstract

The invention discloses an automatic rotation device for an inclinometer tube, which includes: a drive mechanism, including a drive motor and a driver for controlling the drive motor, for driving the rotation of a rotatable inclinometer tube; a rotation mechanism, including a fixed part and a The fixed part is a rotating part that rotates in the horizontal direction, and the driving mechanism is used to drive the rotating part to rotate in the horizontal direction; the rotatable inclinometer tube is covered with an external casing, and the external casing is embedded in the It is underground and at least extends outside the uppermost fixed inclinometer pipe embedded in the ground; a fastening mechanism is connected to the rotating part, and the rotatable inclinometer pipe is fastened on the fastening mechanism and the rotatable inclinometer pipe The rotating inclinometer tube rotates coaxially with the rotating part. The present invention uses the original standard inclinometer tube in the existing project to carry out simple transformation, and can be connected to the automatic rotation device of the inclinometer tube described in the present invention, which has good engineering adaptability and economy, and greatly improves reliability and stability .

Description

technical field [0001] The invention relates to an inclinometer device, in particular to an automatic rotation device for an inclinometer tube, which is applied in the field of geotechnical engineering and solves the technical problem that the underground inclinometer tube cannot be automatically rotated in the field of geotechnical engineering. Background technique [0002] For related structural projects such as foundation pits, the underground support structure is an important part of it, and it plays a very good role in protecting open excavation projects. However, during the construction process, it is necessary to monitor the deformation of the support structure in order to Prediction and early warning of construction risks, this monitoring item is called underground deep horizontal displacement monitoring, or inclinometer. [0003] At present, the commonly used monitoring method for deep underground horizontal displacement is: pre-embed the inclinometer pipe in the su...

AI Technical Summary

Problems solved by technology

[0012] The purpose of the present invention is to solve the technical problem that the underground inclinometer pipe cannot rotate automatically in the existing geotechnical engineering field

[0013] The invention provides an automatic rotation device for the inclinometer tube, which realizes the automatic rotation of the movable inclinometer in the inclinometer tube, ensures the validity and accuracy of the monitoring data in the long-term automatic monitoring, and solves the existing automatic monitoring of the deep horizontal displacement It is impossible to measure positive and negative in the middle, which leads to the defects of sensor assembly error and zero drift that cannot be eliminated
