In order to solve the problems, the technical scheme adopted by the utility model is as follows:

the utility model provides a vibrations high-sensitivity optic fibre bearing roller, includes carrier roller frame and bearing roller, the extreme point department of carrier roller frame be equipped with fixed lid, fixed cover and be equipped with the recess, the recess in be equipped with the optic fibre and detect the head, the bearing roller that sets up in the carrier roller frame both ends be equipped with monitoring part.

The two ends of the carrier roller frame are respectively provided with grooves and optical fiber detection heads.

The optical fiber detection heads on the plurality of roller frames are respectively connected with an independent optical fiber.

The optical fiber detection heads on the plurality of roller frames are connected in series to the same optical fiber.

The detection part is a mechanical part which generates vibration when the axle center is deviated.

The mechanical part is a circular ring with meshing teeth on the side surface.

Compared with the prior art, the utility model has the beneficial effects that:

compared with the roller frame design in the prior art, the utility model collects the sound vibration information during the operation of the roller frame through the optical fiber detection head, can accurately judge whether the roller on the roller frame has faults, omits the time for a maintainer to remove all the roller in sequence, and the optical fiber detection head serving as a detection component is arranged on the outer side of the roller frame, so that the detection part is not affected when the roller has faults, the installation and the disassembly modes are very simple, the repeated use is realized, and the device is not a disposable alarm device.

Compared with the manual checking scheme in actual production, the automatic checking device can save a large amount of time, can monitor in real time, can feed back in time even if the carrier roller has slight faults, is convenient for daily maintenance and prevents irreversible damage caused by accumulation of the slight faults.

Detailed Description

The utility model is further described below in connection with specific embodiments.

Example 1

As shown in fig. 1 and 2, the present utility model mainly includes a carrier roller frame 2, carrier rollers 3, and fixed covers 1 provided at both ends of the carrier roller frame 2.

The fixed cover 1 and the two ends of the carrier roller frame 2 are provided with mutually matched thread structures or clamping grooves, so that the fixed cover 1 can be stably fixed on the end points of the carrier roller frame 2.

The middle part of the fixed cover 1 is provided with a groove, wherein one groove penetrating through the fixed cover 1 is an optical fiber groove 4 for placing an optical fiber to penetrate through, and the middle part of the optical fiber groove 4 is provided with an optical fiber detection head fixing groove 5 for placing a pickup head.

The pickup scheme adopted in this embodiment is a dual-channel scheme in which all the roller frames 2 are connected in series and pickup monitoring is performed at both ends simultaneously, and is used for the structures of V-shaped rollers or other multi-segment rollers, and the optical fibers respectively arranged at both sides respectively monitor the rollers 3 arranged at both sides.
