Description

Technical Field

[0001] The utility model relates to an installation tool for an eddy current probe. Background Art

[0002] An eddy current sensor is a non-contact linear measurement tool, which can statically and dynamically measure the distance between the surface of the probe and the measured metal conductor non-contact, with high linearity and high resolution. The characteristics of the eddy current sensor are good long-term working reliability, high sensitivity, strong anti-interference ability, non-contact measurement, fast response speed, and not affected by media such as oil and water. 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.

[0003] At present, the probe of the eddy current sensor is fixed through an L-shaped bracket. After fixing, a feeler gauge is required to measure the distance from the rotor measurement end. This measurement method is inaccurate and cannot ensure alignment with the central axis of the rotor. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above problems, thereby providing an installation tool for an eddy current probe.

[0005] The above purpose is achieved by the following technical solutions:

[0006] An installation tool for an eddy current probe, which comprises a several-shaped frame. The upper end and the side of the several-shaped frame are respectively connected with a probe position adjustment bracket, and a probe is fixed on the probe position adjustment bracket.

[0007] The probe position adjustment bracket includes a bottom plate. The bottom plate is connected to the several-shaped frame by bolts. The bottom plate is in sliding fit with an adjustment plate. Four corners of the adjustment plate are respectively fixed with adjustment bolts. The adjustment bolts pass through an η plate and are fixed by adjustment nuts. The probe is fixed on the η plate. Two screw rods are fixed on the η plate, and the screw rods pass through the round holes of a sleeve.

[0008] In the installation tool for an eddy current probe, a spring is sleeved on the screw rod.

[0009] In the installation tool for an eddy current probe, a limit nut is threadedly connected to the screw rod. Advantageous Effects

[0010] 1. By setting the probe position adjustment bracket, the position of the probe and the distance from the measurement end can be adjusted, so that the measurement requirements can be met after the position is fixed.

[0011] 2. When adjusting the probe position adjusting bracket of the present utility model, the sleeve abuts against the rotor end, and the distance between the probe and the measuring end can be measured at any time to ensure the accuracy of the probe installation position.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Referring to Figures 1-4 , an eddy current probe installation tool, which comprises a U-shaped frame 2, and a probe position adjusting bracket 1 is respectively connected to the upper end and the side surface of the U-shaped frame, and a probe 13 is fixed on the probe position adjusting bracket;

[0019] The probe position adjusting bracket includes a bottom plate 9, the bottom plate is connected to the U-shaped frame by bolts, the U-shaped frame has an object passing hole 3, the bottom plate has a strip-shaped hole 18, and the position adjusting plate has a through hole 15 through which the probe can pass. The bottom plate is slidably matched with the position adjusting plate 10. Two sliding holes 19 are opened on the position adjusting plate, and a fixing bolt 20 is fixed on the bottom plate. The fixing bolt passes through the sliding hole and is threadedly connected with a nut. Adjusting bolts 11 are respectively fixed at the four corners of the position adjusting plate. The adjusting bolts pass through the η plate 12 and are fixed by adjusting nuts 17. The probe is fixed on the η plate. Two screws 7 are fixed on the η plate. The screws pass through the round holes of the sleeve 4, a spring 8 is sleeved on the screws, and a limit nut 16 is threadedly connected to the screws.

[0020] Working principle: When in use, referring to Figure 5, fix several types of frames at the rotor 22 through bolts, then adjust the position of each probe through the probe position adjustment bracket, make the adjustment plate slide-fit with the bottom plate, loosen the nuts on the fixing bolts, and slide the sliding plate so that the position of the probe slides. Stop sliding until the probe is aligned with the central axis of the rotor. Then tighten the nuts, turn the limit nut until it reaches the bottom end of the screw rod. Under the action of the spring, the sliding of the sleeve will abut against the surface of the rotor. There is an opening 6 on the sleeve, which can facilitate observing the position of the probe. At this time, the position between the probe and the rotor surface can be read through the scale 5 on it. Then adjust the adjusting nuts of each adjusting bolt. After adjustment, adjust the position of the η plate until the gap between the probe and the rotor surface reaches the specified gap and then stop. Then push the sleeve to compress the spring again, expose the probe, and at the same time turn the limit nut and fix it on the sleeve to limit the position of the sleeve.
