Rapid adjustment and installation mechanism for eddy current displacement sensor

Abstract

The invention discloses a rapid adjustment and installation mechanism for an eddy current displacement sensor. The rapid adjustment and installation mechanism comprises a feed mechanism clamp arranged on a measured part. An eddy current displacement sensor adjustment structure is arranged on an eddy current displacement sensor clamp. The eddy current displacement sensor adjustment structure comprises a feed mechanism fixed portion, a feed transmission portion and a feed mechanism movable portion, wherein the feed mechanism fixed portion is fixedly arranged on the feed mechanism clamp. The movable feed transmission portion is sleeved with the feed mechanism fixed portion. One end of the feed mechanism portion is fixedly arranged on the feed mechanism movable portion. The eddy current displacement sensor is arranged on the feed mechanism moveable portion. After the feed transmission portion is adjusted, the eddy current displacement sensor can be moved, and therefore the distance between the eddy current displacement sensor and the measured object is rapidly adjusted, and the aim of conducting vibration measurement is achieved.

Description

technical field [0001] The invention relates to the field of installation mechanisms for eddy current displacement sensors, in particular to a fast-adjusting installation mechanism for eddy current displacement sensors. Background technique [0002] At present, rotating equipment such as main pumps in nuclear power plants need to temporarily install eddy current displacement sensors for vibration measurement. The current mounting brackets for eddy current displacement sensors are mainly permanently fixed, and temporary mounting brackets are usually in the form of fixed brackets. [0003] The patent number is CN201209597Y, and the Chinese patent titled "Installation Structure of Eddy Current Displacement Sensor" shows an installation structure of an eddy current displacement sensor that is easy to adjust the axial position of the sensor during installation. The installation structure of the eddy current displacement sensor includes a fixed seat, a through hole is opened on t...

AI Technical Summary

Problems solved by technology

[0004] The installation structure of the eddy current displacement sensor solves the problem of changing the axial position of the eddy current displacement sensor due to the locking of the traditional mounting bracket, but it also has some shortcomings, which are manifested in three aspects: first, an external power supply is required to adjust the position of the eddy current displacement sensor , which increases the installation time and the limitation of external power supply conditions; secondly, the adjustable range of the eddy current displacement sensor of this installation structure is small, and it cannot be adjusted for a long distance and within a certain range; thirdly, the installation structure itself cannot be repeatedly disassembled and assembled. The structure used for fixing is fixed by a single-sided nut, repeated disassembly and assembly will easily lead to failure of the compression arm

Does not meet the requirements of temporary, quick and repeated installation
