No. Construction process, original construction process, shrinkage rope friction hoist, first rope, quick adjuster, retractable rope, required time, personnel required time, construction preparation, lock, north tank, fourth floor, south tank, side, I-beam, flat card People, locks on the third floor, pull down the cattle lock rope, lock the third floor, hit the sling rope to lift the south tank, use the small winch to lift the chain guide, and manually pull the chain to lift the south tank. You only need to carry out the individual, personal operation. With the corresponding knob, the individual checks the progress and status of the adjustment and is responsible for communicating with other operators. Through comparative demonstration, the application of BYTS-4×28/400 in the auxiliary shaft shrinkage rope has obvious effect, which simplifies the process of shrinking the rope, shortens the construction time, saves labor, reduces the labor intensity of the construction workers, and solves the problems of on-site management. The electromechanical and hydraulic integration technology is adopted in the design structure, and the PLC centralized control mode is adopted, which is simple and convenient to operate. The lock rope mechanism adopts the cross-locking control mode, and the operation is stable, which reduces the probability of accidents.
The hoist gear reducer is a low-speed heavy-duty device that transmits motion and power. Its operating state can be reflected by the rich information carried by the vibration signal. In the event of a fault, its vibration signal exhibits a strong non-stationary nature, which is manifested by complex amplitude modulation, frequency modulation or integrated modulation characteristics due to strong noise interference. The high-frequency center frequency of the modulated signal corresponds to the gear pair meshing frequency and its harmonic frequency, or the transverse natural frequency of the gear; the modulation frequency corresponds to the rotational frequency of the faulty gear, so various demodulation methods can be used to extract from the complex modulated signal. A modulation characteristic reflecting the gear failure is achieved to achieve a precise fault diagnosis of the gearbox.
