Abstract

Disclosed is a vibration isolation structure which is an improvement in vibration noise control of a traction machine and prevents vibration noise of elevators from disturbing people. A rigid vibration isolation base is arranged below a steel beam of an engine base of the traction machine, a rigid bearing plate is arranged on a load-bearing steel beam, a rubber damper is mounted between the steel beam of the engine base of the traction machine and the rigid vibration isolation base, a damping vibration isolator is mounted between the rigid vibration isolation base and the rigid bearing plate, and second vibration isolation effect is formed by the rubber damper and the damping vibration isolator, so that vibration noise transmitting through the load-bearing steel beam of the traction machine is reduced effectively.

Description

A kind of vibration insulation structure
Affiliated technical field
The utility model relates to a kind of to the transformation of lift machine Noise and Vibration Control, prevents the technology that the hoist machine vibration noise disturbs residents.
Background technique
Vibration that elevator produces in the running and noise can exert an influence to people, and the noise of hoist machine operation is to influence bigger main noise source in many noise sources of elevator.Lift machine is machine supporting beams and the binding of building structure formation rigidity fixedly.Therefore constitute noise of elevator mainly propagates " overhead speaker " to the load-bearing girder steel.Lift machine produces stronger vibration when running and speed change; Vibration mainly reaches the indoor structure-borne that gives off noise again of resident with the form of elastic wave through machine beam and hoistway body of wall, just receives the influence of noise that is produced by vibration of elevator during resident's rest.
In existing vibration of elevator noise control renovation technique; Real core rubber damper often is installed between hoist machine pedestal and load-bearing girder steel, friction in the real core rubber damping spacer, critical damping is bigger; During through resonance region also can safety use, can not produce excessive vibration.But the natural frequency of real core rubber damper is higher, and the vibration isolation efficiency of low frequency configuration noise is lower, can not satisfy the vibration isolation requirement.Simultaneously, because the stressed skewness weighing apparatus of each point of load application of hoist machine pedestal, the tiling uniformly of real core rubber damper can cause real core rubber damper to receive force unbalance.
Summary of the invention
Under hoist machine support girder steel, the rigidity vibro-damping mount is set; On the load-bearing girder steel rigid bearing plate is set; Between hoist machine support girder steel and rigidity vibro-damping mount, rubber shock absorber being installed, between rigidity vibro-damping mount and rigid bearing plate, damping isolator is installed, rubber shock absorber and damping isolator form two-stage vibration isolation; Improve vibration isolation efficiency, prevent the vibration noise structure-borne.
The utility model solves the technological scheme that its technical problem adopted: the rigidity vibro-damping mount that steel material structure is set in hoist machine support bottom; Load-bearing girder steel top is provided with rigid bearing plate; Rigid bearing plate is the steel plate of thickness 16~20mm; Rigid bearing plate and load-bearing girder steel use high-strength bolt reliably to install, and the rigidity vibro-damping mount is consistent with rigid bearing plate plane specification, reservation hauling hope, to the position of pouring weight traction sheave.Between hoist machine support girder steel and rigidity vibro-damping mount, rubber shock absorber is installed; It is low that natural frequency is installed between rigidity vibro-damping mount and the rigid bearing plate; The damping isolator that damping ratio is high is to satisfy elevator frequent needs through resonance region in startup, braking and stopping process.Damping isolator is installed according to the stressed distributing position of each point of load application of hoist machine pedestal; With total vertical rigidity center and the requirement of hoist machine support total centre of gravity on same vertical line of satisfying damping isolator; Damping isolator has anti-shearing device, with the level of hoist machine and vibrating isolation system in the restriction running to displacement.
The beneficial effect of the utility model is that through two-stage vibration isolation is set, minimizing hoist machine vibration noise protects the resident not receive the influence of hoist machine vibration noise through the structure-borne of load-bearing girder steel.
