Abstract
The utility model provides a vibration damping muffler for the traction machine of an elevator, which comprises vibration damping bases, vibration dampers, connecting pieces and I-steel members. The vibration dampers are arranged on the I-steel members. The vibration damping bases are fixedly arranged on the vibration dampers so as to form vibration damping units. At least two vibration damping units are connected into one piece through the connecting pieces. The dynamic properties of the muffler are adjusted through the parameters of the vibration dampers, such as elastic modulus, damping coefficient and the like, so that the optimum vibration isolation range and the optimum vibration damping effect are realized. A special requirement proposed on the natural frequency of the muffler is at least lower than the excitation frequency of the traction machine of an elevator. Preferably, the natural frequency of the muffler is no more than one half of the natural frequency of the traction machine of the elevator.
Description
[technical field]
The utility model relates to a kind of lift machine vibration-absorbing and silencing device.
[technical background]
The vibration that existing elevator produces when moving can form noise, has a strong impact on the normal life of resident family.Though at present the noise that begins to administer this respect is arranged, regulation effect is undesirable, because high frequency noise relatively easily administers, but low frequency noise still exists.
Close product just utilizes the rubber vibration isolation principle to carry out vibrationproof merely and handles, and can not eliminate the vibration noise that produces fully, and damping efficiency is low, the effectiveness in vibration suppression endurance is poor.This is because this vibration reducing measure is not considered the matching problem of free running frequency of free frequency and the electric vibrationproof object itself of shock absorbing material itself.So reasonably selection and suitable vibration damping equipment are the key factors that reduces noise.
[summary of the invention]
To the problems referred to above, the lift machine vibration-absorbing and silencing device of the utility model comprises snubber base, vibration damper, link and I-steel, and said vibration damper places on the said I-steel, and said snubber base is fixed on the said vibration damper, forms vibration absorption unit; Said at least two damper units are connected in one through said link.
In described silencing apparatus, mainly utilize the parameters such as Young's modulus and damping constant of vibration damper, adjust the dynamic performance of silencing apparatus, thereby reach best vibration isolation scope and best effectiveness in vibration suppression.So the free frequency to said silencing apparatus has specific requirement, at least should be lower than the energizing frequency of lift machine, preferably, the free frequency of said silencing apparatus is no more than the half the of lift machine free frequency.
Said vibration damper can be the U font, and back-off is on said I-steel.Said link is at least two, is connected to the two ends of said vibration absorption unit.
The utility model has taken into full account the problem that the frequency of vibrationproof object and vibration damping equipment is mated each other, thereby vibration isolation efficiency is high, and especially higher to the efficient of low frequency vibration isolation, the effectiveness in vibration suppression endurance is strong.Can thoroughly solve the low frequency noise of elevator.
[description of drawings]
Fig. 1 is the long splice composition of the utility model preferred embodiment.
[embodiment]
Referring to embodiment shown in Figure 1, the lift machine vibration-absorbing and silencing device of the utility model comprises snubber base 1, vibration damper 2, link 3 and I-steel 4, and vibration damper 2 places on the I-steel 4, and snubber base 1 is fixed on the vibration damper 2, forms vibration absorption unit; Said at least two damper units are connected in one through link 3.When lift machine is connected on the lift machine of the utility model, can reduce noise through vibration damper 2.
In the silencing apparatus of present embodiment, mainly utilize the parameters such as Young's modulus and damping constant of silencing apparatus, adjust the dynamic performance of silencing apparatus, thereby reach best vibration isolation scope and best effectiveness in vibration suppression.So the free frequency to said silencing apparatus has specific requirement, at least should be lower than the energizing frequency of lift machine, preferably, the free frequency of said silencing apparatus is no more than the half the of lift machine free frequency.
Be the free frequency of adjustment silencing apparatus, vibration damper 2 can adopt high resilience rubber, and the damping material that high resilience rubber and damping capacity are good is synthetic to be made.Wherein damping material adopts restriction damping layer, and promptly damping material places between the sheetmetal, thereby has improved the Young's modulus of damping material.Vibration forms the secondary vibration damping through staggered decay back, can significantly reduce the low-frequency range vibration noise, and vibration isolation is wider.
Preferred embodiment as shown in Figure 1, vibration damper 2 is the U font, back-off is on said I-steel 4.Link 3 is two, is connected to the two ends of said vibration absorption unit, and 3 lockings are connected with link with vibration absorption unit with nut.
The utility model has taken into full account the problem that the frequency of vibrationproof object and vibration damping equipment is mated each other, thereby vibration isolation efficiency is high, and especially higher to the efficient of low frequency vibration isolation, the effectiveness in vibration suppression endurance is strong.Can thoroughly solve the low frequency noise of elevator.
Vibration is more obvious through secondary decay back effect of vibration and noise reduction, has adopted restriction damping layer, and longer service life does not influence the original ride quality of elevator, does not influence the periodic maintenance of elevator components, more energy-conserving and environment-protective; There is not any pollution.
