Description
Technical Field
The utility model relates to an eddy current sensor's installing support.
Background
In order to ensure stable operation of large-sized high-speed rotating equipment, a vibration sensor for measuring rotor shaft vibration and a shaft displacement sensor are generally mounted on large-sized high-speed rotating equipment such as a centrifugal compressor, and an eddy current sensor is generally used for detecting signals of shaft vibration and shaft displacement.
The eddy current sensor needs to be stably and firmly installed on a shaft end machine shell, the sensor is generally in the shape of a screw rod and needs to be rotatably installed on a sensor installation seat of the machine shell, the eddy current sensor is generally provided with a section of special cable, an aviation plug is connected with an extension cable to send a signal to a secondary meter, a cable plug needs to be disassembled when the sensor is installed or disassembled, and the sensor is screwed in or screwed out together. The cable connecting the cable and the sensor is easy to be damaged by carelessness when the sensor is dismounted or mounted, and the whole sensor is scrapped. During installation and debugging, the sensor needs to be rotated on site to adjust the distance between the sensor and the shaft, a secondary meter needs to be connected during adjustment of the distance, and the voltage value is measured on the secondary meter to reflect the change of the distance between the sensor and the shaft until the required voltage is reached (namely the requirement of the installation distance is reached). In the debugging process, a cable needs to be connected and the sensor needs to be rotated, so that the cable is easy to be stiff, and the sensor is easy to scrap for a long time.
The sensor is required to be dismantled in order to prevent the eddy current sensor from being damaged when the equipment needs to be overhauled every time, and due to the structural form of the sensor, the debugging after the dismantling and the installation is troublesome.
Disclosure of Invention
An object of the utility model is to provide an eddy current sensor's installing support can conveniently debug eddy current sensor, prevents that the artificial damage condition from appearing in eddy current sensor.
The utility model aims at realizing like this, an eddy current sensor's installing support, including the sensor mount pad, install a fixed pipe on the sensor mount pad, fixed pipe medial extremity is setting up interior locking nut, fixed pipe outside end is setting gradually big dish and small dish from interior to exterior, even interval is setting up locking bolt in the big dish outer peripheral edges, the coaxial suit in fixed pipe outside end is setting up a middle part activity adjusting collar, middle part activity adjusting collar both ends are fixed respectively and are setting up a character cut in bas-relief shape positioning seat, the character cut in bas-relief shape positioning seat with small dish cooperation suit together, even interval is setting up fixed adjusting bolt and locking the small dish with it on the radial outer peripheral edges of character cut in bas-relief shape positioning seat of middle part activity adjusting collar outside end, the same cooperation is setting up an outside activity adjusting collar in the character cut in bas-relief shape positioning seat of middle part activity adjusting collar outside end, outside activity adjusting collar is setting gradually the, The eddy current sensor is sleeved in a sleeve, and the sleeve is coaxially matched, sleeved in the fixed pipe, the movable adjusting sleeve and the external movable adjusting sleeve and locked by the locking nuts at two ends.
The utility model discloses during the use, loosen each lock nut, just can conveniently stretch, the rotatory sleeve pipe of installing eddy current sensor, eddy current sensor is when the debugging, is in all the time the intraductal, the manual work can not touch eddy current sensor. After the position of the eddy current sensor is adjusted, locking nuts at all positions are locked. The sensor can be disassembled and debugged on the premise of not disconnecting in the equipment maintenance process, the disassembling difficulty of the shaft vibration/shaft displacement eddy current sensor is reduced, and the sensor body and the sensor lead are guaranteed not to be damaged to the maximum extent when the sensor is disassembled and assembled. The clearance between the sensor and the shaft can be adjusted on the premise of not removing the wire, and the adjustment precision and speed are also greatly improved.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention;
fig. 2 is an enlarged schematic view of the movable adjusting sleeve of the present invention.
Detailed Description
An installation support of an eddy current sensor is disclosed, as shown in fig. 1 and fig. 2, comprising a sensor installation base 7, a fixed pipe 9 is installed on the sensor installation base 7, an inner locking nut 8 is arranged at the inner side end of the fixed pipe 9, a large disc 13 and a small disc 11 are sequentially arranged at the outer side end of the fixed pipe 9 from inside to outside, locking bolts 14 are uniformly arranged at intervals in the outer periphery of the large disc 13, a middle movable adjusting sleeve 12 is coaxially sleeved at the outer side end of the fixed pipe 9, a concave-shaped positioning seat 5 is respectively fixedly arranged at two ends of the middle movable adjusting sleeve 12, the concave-shaped positioning seat 5 is matched and sleeved with the small disc 11, fixed adjusting bolts 4 and 6 are uniformly arranged at intervals on the radial outer periphery of the concave-shaped positioning seat 5 and are used for locking the small disc 11, an outer movable adjusting sleeve is also matched and arranged in the concave-shaped positioning seat at the outer side end of the middle movable adjusting sleeve 12, the external movable adjusting sleeve is sequentially provided with a small disc, a large disc 13 and an external locking nut 3 from inside to outside, the eddy current sensor 2 is sleeved in a sleeve 10, and the sleeve 10 is coaxially matched and sleeved in the fixed pipe 9, the movable adjusting sleeve 12 and the external movable adjusting sleeve and is locked by the internal locking nut 8 and the external locking nut 3 at two ends. The distance and the angle between the eddy current sensor 2 and the measured shaft 1 can be conveniently adjusted by loosening the inner locking nuts 8 and the outer locking nuts 3 and fixing the adjusting bolts 4 and 6.
