Description

With the high-speed elevator cage for improving blimp

Technical field

The utility model belongs to elevator technology field, is related to a kind of noise-reducing structure, and particularly a kind of band improves blimp High-speed elevator cage.

Background technology

Car be elevator to carry and transport personnel and goods and materials box-shaped space.Car be elevator be used for transporting passengers or The sedan-chair body component of goods and other load.Car space is closing leg, must not have it in addition to necessary gateway and air vent He is open (small part national requirements car top opens up security window), and car cab is by nonflammable and do not produce the material of pernicious gas and smog Material composition.For the safety of occupant and comfortable, car entrance and internal free height cannot be less than 2 meters.To prevent occupant excessive And causing overload, the effective area of car must be limited.

In the lift car of existing high-speed cruising, the noise ratio of cage operation is larger, in order to reduce the noise of car, typically Blimp is installed additional using the upper and lower side in car, to isolate or blocking noise.But existing blimp not only processes cumbersome, deadweight Weight, it is easy to cause the generation of security incident, hidden danger is very big, and checking resistance noise-reducing DeGrain, and noise pollution is serious.

Elevator is run in hoistway, as the increase of car speed will bring the aerodynamics problem such as aerodynamic noise, shadow The security and comfortableness of elevator are rung.And noise of elevator is mainly what is triggered by air drag and mechanical oscillation.Elevator is in well Very big windage is produced when up and down reciprocatingly being run in road, these resistances produce windage noise with car effect；Additionally, due to air Flow velocity is sharply increased, and air-flow produces very big separation and discontinuous whirlpool in carriage body afterbody, and this discontinuous whirlpool constantly takes off Falling and developing can make the pressure in vortex field produce big ups and downs generation eddy current crack.Many noises of elevator are caused by vibration , this vibration is referred to as gas noise and solid is made an uproar to be propagated in the form of elastic wave in air, solid dielectric Sound.It is necessary that noise reduction is carried out to lift car in order to ensure the comfortableness of lift car passenger.

The purpose of this utility model is there is above mentioned problem for existing technology, it is proposed that one kind is by setting according to wind The elastic buffer disk of power activity, to control air intake path, so as to realize that the band of erasure effect improves the express elevator sedan-chair of blimp Railway carriage or compartment.

The purpose of this utility model can be realized by following technical proposal：With the high-speed elevator cage for improving blimp, Including car casing, blimp is respectively provided with the top and bottom of the car casing, the blimp is in the dome-shaped of evagination, institute Stating blimp includes drag reduction shell and sound-insulating inner layer, and the drag reduction shell includes the outer ring housing of annular, the outer ring housing Center sets elastic buffer disk, is connected between the elastic buffer disk and outer ring housing by rubber ring, the rubber ring On open some air vents, air exhaust passage is set between the outer ring housing and the sound-insulating inner layer, the air exhaust passage extension Exhaust outlet is set to the edge of the blimp, the elastic buffer disk is included positioned at the elastic metallic disk in outside and positioned at interior The cushion pad of side, stays between the elastic metallic disk and cushion pad and sets buffering deformation gap, and the inner side of the cushion pad sets bullet Spring layer.

The mode of action of high-speed elevator cage that this band improves blimp is：Lift car is during up, car case Blimp at the top of body is impacted by wind-force, spring layer compression by lower pressure, and the height of elastic buffer disk declines, And then rubber ring is stretched, and make the fully open expansion of the air vent on rubber ring, it is distinguished and admirable that air exhaust passage is entered by air vent, in air draft Alveolate texture is entered by sound-absorption hole in passage and carries out sound deadening, it is remaining distinguished and admirable finally to be discharged by exhaust outlet.Elevator car Railway carriage or compartment is during descending, and the blimp of car casing bottom is impacted by wind-force, and action principle is ibid.When lift car stops During operation, distinguished and admirable impact disappears, and elastic buffer disk resets in the presence of spring layer, and the air vent on rubber ring, which all reduces, to close Close.

In the high-speed elevator cage that above-mentioned band improves blimp, the spring layer includes some helical springs, some The helical spring is arranged in systematicness and laid, and the spacing between the adjacent helical spring is 8cm~15cm.

In the high-speed elevator cage that above-mentioned band improves blimp, some sound-absorbings are set on the surface of the sound-insulating inner layer Hole, the inside of the sound-insulating inner layer sets alveolate texture, and the sound-absorption hole is connected with alveolate texture.

In the high-speed elevator cage that above-mentioned band improves blimp, some air intakes are opened on the outer wall of the outer ring housing Hole, the fresh air inlet connects the air exhaust passage.

In the high-speed elevator cage that above-mentioned band improves blimp, drag reduction sea is covered with the outer wall of the outer ring housing Continuous layer.Impulsive force of the wind-force to outer ring housing is weakened by drag reduction spongy layer.

In the high-speed elevator cage that above-mentioned band improves blimp, noise reduction perisporium is set in the air exhaust passage, it is described Noise reduction perisporium has the sponge top layer of undulate.Weaken distinguished and admirable dynamics and speed, Jin Erda using corrugated sponge top layer To the effect of noise reduction.

In the high-speed elevator cage that above-mentioned band improves blimp, the car casing have car floor, sedan-chair wall, car top and Gate, cushion is set between the car top, car floor and the blimp.Separate the shake produced by wind-force by cushion Trend car casing is driven.

Compared with prior art, the high-speed elevator cage of this band improvement blimp utilizes elastic deformation and automatically reset spy Point, by setting the elastic buffer disk according to wind-force activity, to control air intake path, so as to realize erasure effect.This practicality is new Type has the features such as simple in construction, reliable effect, strong flexibility.
