Abstract
The utility model discloses a kind of sound insulation house for traction machine test, including：The wall at room four sides and the floor of the ceiling of top surface and bottom surface, wall and the ceiling inner surface post acoustic material, door is offered at least one side wall, the inner surface of door also posts sound insulation and surveys material, through hole is further opened with wall, through hole connects the interior or exterior space of sound insulation house, and a power transmission shaft runs through the through hole, and the gap between through hole and the power transmission shaft is filled using acoustic material.By sticking acoustic material in the inner surface in room and outer surface, it can so ensure be influenceed by ambient noise substantially in sound insulation house, when testing operating noise of the traction machine under various operating modes, will not be influenceed by extraneous background noise, the accuracy of test is higher.Through hole is the passage that the traction machine as peace turn internally is mutually linked with external load test equipment, the technical scheme filled using bearing plus acoustic material, so realizes the sound insulation of through hole substantially.
Description
Technical field
It the utility model is related to a kind of sound insulation test room, more particularly to a kind of sound insulation house for traction machine test.
Background technology
Actuating unit of the traction machine as elevator, it is the core component of elevator, whether the service behaviour of traction machine is stablized, and needs
Will be by testing the work in every parameter of traction machine, to ensure the job stability of elevator.Elevator in the running make an uproar by a part
Sound comes from traction machine, if traction machine noise is excessive, can cause the sense of discomfort of passenger in lift car, it is necessary to be directed to
Noise problem is tackled.Therefore need just find out improvement after traction machine noise under testing different operating modes.
The content of the invention
The utility model overcomes the deficiencies in the prior art, there is provided a kind of sound insulation house for traction machine test.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of sound insulation house for traction machine test,
Including：The wall at room four sides and the floor of the ceiling of top surface and bottom surface, it is characterised in that the wall and the smallpox
Plate inner surface posts acoustic material, and door is offered at least one side wall, and the inner surface of door also posts acoustic material, the wall
Be further opened with through hole on body, the interior or exterior space of the through hole connection sound insulation house a, power transmission shaft run through the through hole, the through hole and
Filled using acoustic material in gap between the power transmission shaft.
In one preferred embodiment of the utility model, bearing is installed, the bearing is embedded in described logical on the power transmission shaft
In hole.
In one preferred embodiment of the utility model, the through hole is the waist-shaped hole of the extension vertically carried out.
In one preferred embodiment of the utility model, acoustic material is posted at the crack between a door and its frame between door and doorframe.
In one preferred embodiment of the utility model, the exterior surface of wall posts acoustic material.
In one preferred embodiment of the utility model, the acoustic material is soundproof fiberboard or sound insulation asbestos board.
In one preferred embodiment of the utility model, at least one noise testing device is provided with the sound insulation house.
In one preferred embodiment of the utility model, the noise testing device is sound level meter.
The utility model solves defect present in background technology, and the utility model possesses following beneficial effect：
（1）By sticking acoustic material in the inner surface in room and outer surface, can so ensure basic in sound insulation house
It will not be influenceed by ambient noise, will not be by extraneous background when testing operating noise of the traction machine under various operating modes
The influence of noise, the accuracy of test are higher.
（2）Through hole is the passage that the traction machine as peace turn internally is mutually linked with external load test equipment, and it is logical
Cross power transmission shaft to be connected, in order to prevent excessive sound from penetrating sound insulation house by through hole, filled using bearing plus acoustic material
Technical scheme, so realize the sound insulation of through hole substantially.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples；
Fig. 1 is the structure chart of preferred embodiment of the present utility model；
In figure：1st, wall；2nd, through hole；3rd, power transmission shaft；4th, bearing；5th, acoustic material.
Embodiment
The utility model is described in further detail presently in connection with drawings and examples, these accompanying drawings are simplified
Schematic diagram, only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the structure relevant with the utility model
Into.
As shown in figure 1, a kind of sound insulation house for traction machine test, including：The wall at room four sides and the day of top surface
Card and the floor of bottom surface, wall and the ceiling inner surface post acoustic material, are pasted at the crack between a door and its frame between door and doorframe
There is acoustic material, exterior surface of wall posts acoustic material, and door is offered at least one side wall, and the inner surface of door also posts sound insulation
Material, by sticking acoustic material in the inner surface in room and outer surface, can so ensure in sound insulation house substantially will not be by
, will not be by extraneous background noise when testing operating noise of the traction machine under various operating modes to the influence of ambient noise
Influence, the accuracy of test is higher.
Through hole, the interior or exterior space of the through hole connection sound insulation house are further opened with wall, a power transmission shaft runs through the through hole,
Filled using acoustic material in gap between the through hole and the power transmission shaft.Bearing is installed, the bearing is embedding on power transmission shaft
In the through hole, through hole is the waist-shaped hole of the extension vertically carried out.Through hole is the traction machine as peace turn internally
The passage being mutually linked with external load test equipment, it is connected by power transmission shaft, in order to prevent excessive sound from passing through
Through hole penetrates sound insulation house, the technical scheme filled using bearing plus acoustic material, so realizes the sound insulation of through hole, bearing substantially
The friction between power transmission shaft and through-hole wall can be prevented.
Waist-shaped hole can conveniently adjust the height and angle of power transmission shaft, to hold in the mouth the equipment of power transmission shaft and different height
Connect.
Acoustic material is soundproof fiberboard or sound insulation asbestos board, and at least one noise testing device is provided with sound insulation house,
Noise testing device is sound level meter.
It is above enlightenment according to desirable embodiment of the present utility model, it is complete by above-mentioned description, related personnel
Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought.This item utility model
Technical scope be not limited to content on specification, it is necessary to determine the technical scope according to the scope of the claims.
