Description

Technical Field

[0001] The invention relates to the technical field of eddy current displacement sensor accessory components, and in particular to a lifting and adjustable eddy current displacement sensor mounting base. Background Art

[0002] Eddy current displacement sensor is a non-contact continuous measurement of the distance between the measured metal conductor and the probe surface. It has the advantages of good long-term working reliability, wide measurement range, high sensitivity, high resolution, fast response speed, strong anti-interference ability, unaffected by media such as oil and dirt, and simple structure. It is often used for long-term real-time monitoring of parameters such as shaft displacement, shaft vibration, and shaft speed of large rotating machinery, analyzing the working condition and cause of failure of the equipment, and effectively protecting and predicting the equipment.

[0003] The installation of eddy current displacement sensors requires a fixed base, and the base needs to be processed according to the installation position before measurement, which causes the installation preparation work of the eddy current displacement sensor to consume a long time and effort; and the height of the traditional eddy current displacement sensor installation base cannot be adjusted, and the position of the mounting hole cannot be adjusted, making it difficult to adapt to different measuring shaft diameters and measuring heights. Summary of the Invention

[0004] In view of this, the present invention provides a lifting and adjustable eddy current displacement sensor mounting base, which reduces the installation preparation time of the eddy current displacement sensor. The height of the device and the position of the sensor mounting hole can be adjusted, which is suitable for measuring different shaft diameters and has a wider range of applications.

[0005] A lifting and adjustable eddy current displacement sensor mounting base includes a V-shaped bracket, an adjustable slider, a vertical bracket and a fixed base; the V-shaped bracket is provided with a slide groove on both wings, and the adjustable slider is installed on the slide grooves on the left and right wings respectively; the vertical bracket is fixedly connected to the V-shaped bracket, and the height of the vertical bracket is adjusted by an adjustment knob; the fixed base is fixed to the foundation by fastening bolts, and the fixed base is used to fix the vertical bracket.

[0006] Furthermore, the left and right wings of the V-shaped bracket are symmetrically arranged at an angle of 90 degrees and have sufficient structural strength.

[0007] Furthermore, the vertical bracket and the V-shaped bracket are fixed by bolts or welding.

[0008] Furthermore, the adjustable slider on the V-shaped bracket can be moved and fixed along the slide groove, and the eddy current displacement sensor is fixed to the outer surface of the shaft through the adjustable slider to meet the measurement requirements of different shaft diameters.

[0009] Furthermore, the height of the V-shaped bracket is adjusted by a vertical bracket to meet the measurement requirements of different height positions.

[0010] Beneficial effects:

[0011] 1. An adjustable slider is provided on the V-shaped bracket of the present invention. The slider moves in the slide grooves on the two wings of the V-shaped bracket to adapt to different measured shaft radii. Assuming that the two extreme positions of the slider movement correspond to the measured shaft radii R1 and R2 respectively, the lifting adjustable eddy current displacement sensor mounting base can adjust the measured shaft radius to any value within the range of R1 to R2 through the adjustable slider.

[0012] 2. The present invention uses a vertical bracket to adjust the height of the V-shaped bracket. Assuming that the two limit values of height adjustment are a and b, the height of the center line of the measured shaft can be adjusted by adjusting the knob of the vertical bracket. Adjust any value within the range. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical bracket 4 adjusts its own height by adjusting the knob 5; the fixed base 6 is fixed to the foundation by fastening bolts 7.

[0018] like Figure 2As shown, the height of the vertical bracket 4 is adjusted to the height a by adjusting the knob 5, and then the left and right adjustable sliders 2 are moved and fixed to the position closest to the outer surface of the shaft with a radius of R1, thereby achieving measurement under the conditions of minimum shaft radius R1 and minimum axis height a.

[0019] The eddy current displacement sensor mounting base adjusts the height of the vertical bracket 4 to the height b by adjusting the knob 5, and then moves and fixes the two adjustable sliders 2 on the left and right to the position closest to the outer surface of the shaft with a radius of R2, thereby achieving measurement under the conditions of maximum shaft diameter R2 and maximum height b.

[0020] In addition, the eddy current displacement sensor mounting base can be adjusted to the height of the vertical bracket 4 by adjusting the knob 5 as needed. Then move the left and right adjustable sliders 2 and fix them to the position closest to the outer surface of the shaft (the shaft radius is any value between R1 and R2).
