Abstract
The invention discloses a pedestal of an elevator traction machine and a method for reducing running noise of an elevator. The pedestal of the elevator traction machine comprises a base and a rubber gasket, wherein the base is made of channel steel or cast iron; a mounting hole for mounting the elevator traction machine is formed on the base; the rubber gasket is arranged above the base; and a through hole coaxial with the mounting hole is formed on the rubber gasket. The pedestal is provided with the rubber gasket based on the traditional base made of the channel steel or the cast iron, and the flexible rubber gasket is positioned between the elevator traction machine and the rigid base when the elevator traction machine is mounted, so the traditional direct rigid connection between the elevator traction machine and the rigid pedestal is changed, the conduction of the noise and vibration when the elevator runs is effectively reduced, the resonance of sound waves is avoided, and the comfortability for passengers to take the elevator is improved. In addition, the pedestal is simple in setting.
Description
Technical field
The present invention relates to the elevator field, particularly a kind of method that is used to that the base of elevator traction machine is installed and reduces the elevator running noises.
Background technology
At present, known elevator traction machine is to be directly installed on the frame base that a channel-section steel or cast iron makes, and with bolt towing machine is fixed on the frame base, and being connected between the girder steel of base and elevator member is directly to use bolt.Though simple in structure, connection failure-free advantage that this connection has, but owing to be to be rigidly connected, the vibration, electromagnetic noise, motor braking (release) noise that are produced during the elevator traction machine operation, the girder steel that is transmitted to that can have no obstacle, produce resonance inevitably, and progressively spread again, be transmitted to passenger's cab, cause the passenger in the elevator cage to experience human discomfort.Reducing the elevator running noises, is one difficulty that manufacturing industry of the lift research is captured.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, the dry sound of the base that a kind of improved elevator traction machine is provided when reducing the elevator operation.
The present invention also will provide a kind of method that reduces the elevator running noises simultaneously.
For solving above technical matters, a kind of technical scheme that the present invention adopts is as follows:
A kind of base of elevator traction machine, it comprises the pedestal of being made by channel-section steel or cast iron, offer the mounting hole that is used to install elevator traction machine on this pedestal, described base also comprises the rubber pad that is arranged on the pedestal top, offers the through hole with the mounting hole coaxial inner conductor on the described rubber pad.
Preferably, described rubber pad is the non-sulphur adjustment type poly-chloroprene rubber of shore hardness between 90 ~ 96 D.The storage stability of this kind rubber, fuel resistance, anti-non-polar solvents are all good, and also have good resistance to effect of heat and lower compressive deformation.
According to one aspect of the invention, the height of rubber pad is 40-80mm, and preferred 45-55mm is 50mm for example.
According to another aspect of the invention, the salient that rubber pad has the vibration damping portion that is fitted on the pedestal upper surface and raises up and form from the dual-side of vibration damping portion, through hole is opened in the vibration damping portion.At this moment, the height of vibration damping portion is preferably 40-80mm, more preferably 45-55mm.The height of salient is preferably 5-15mm.Salient can play the ccasual positioning action when mounted.
The another technical scheme that the present invention takes is: a kind of method that reduces the elevator running noises, it is that to set up between pedestal that is used to install elevator traction machine and elevator traction machine be the rubber pad between 90 ~ 96 D for 40-80mm, shore hardness highly.
The height of described rubber pad is preferably 45-55mm.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
Channel-section steel that the present invention is traditional or castiron pedestal are provided with rubber pad, when elevator traction machine is installed, flexible rubber pad is between the pedestal of towing machine and rigidity, changed directly being rigidly connected between traditional elevator traction machine and the rigid base, the noise when effectively reducing the elevator operation and the conduction of vibration, avoid the resonance of sound wave, improved the comfort level the when passenger takes elevator.In addition, the present invention is provided with simply.
Description of drawings
The present invention will be further described in detail below in conjunction with accompanying drawing and concrete embodiment:
Fig. 1 looks cross-sectional schematic for the master according to base of the present invention;
Fig. 2 is the schematic top plan view according to base of the present invention;
Wherein: 1, pedestal; 10, mounting hole; 2, rubber pad; 20, through hole; 21, vibration damping portion; 22, salient.
The specific embodiment
As depicted in figs. 1 and 2, comprise in pedestal of making by channel-section steel or cast iron 1 and four rubber pad 2(figure that are arranged on pedestal 1 top according to the base of the elevator traction machine of present embodiment and only to show 2), pedestal 1 has corresponding respectively being arranged on pedestal 1 upper surface of mounting hole 10 positions of 10, four rubber pads 2 of mounting hole that is used to install elevator traction machine.Rubber pad 2 is divided into vibration damping portion 21 that is fitted on pedestal 1 upper surface and the salient 22 that is positioned at vibration damping portion 21 both sides, offer through hole 20 in the vibration damping portion 21 with mounting hole 10 coaxial inner conductors, during installation, screw fixes with the frame of elevator traction machine through mounting hole 10, through hole 20.
In order to prevent that rubber pad 2 is subjected to the pollution of greasy dirt and reduces intensity when mounted, shock pad 2 adopts non-sulphur adjustment type (W type) poly-chloroprene rubber to make.This type rubber is made the conditioning agent of relative molecular mass with DDM dodecyl mercaptan when polymerization, so be called MERCAPTAN MODIFIED CHLOROPRENE RUBBERS again.Owing to do not contain many sulphur chain in its molecular backbone, so storage stability is better; The fuel resistance of poly-chloroprene rubber, anti-non-polar solvents are all good, and have good resistance to effect of heat and lower compressive deformation.In addition, in order to ensure the thickness of four shock pads 2 after the weight of deadweight of bearing elevator traction machine and cab, keep the deflection of basically identical, the Hardness Control of rubber damper is between shore hardness (SHORE) 90 ~ 96 D, and every four conformability according to hardness preferably cooperate.
The number and the size that it will be understood by those skilled in the art that rubber pad can be adjusted according to the size of elevator traction machine and pedestal.In this example, the height (thickness) of the vibration damping portion 21 of rubber pad 2 is 50mm, and the height of salient 22 (thickness) is 10mm, and width is 8mm.Salient 21 can play the effect of interim location when mounted.
Adopt the base of present embodiment that elevator traction machine is installed, rubber pad is between the pedestal and elevator traction machine of rigidity, utilize buffering, the damping of vibrations of rubber, can stop, slow down the vibration of towing machine operation, the diffusion and the conduction of noise effectively, thereby reach the noise reduction vibration damping, increase the effect of the driving comfort of elevator operation.
More than the present invention has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences of doing according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
