Abstract
The utility model discloses a kind of lift cars, include car body, it is characterised in that：Integrated air-flow buffer room is equipped at the top and bottom of the car body, it is equipped with interior air-flow concentration chamber in the air-flow buffer room, the position of the corresponding air-flow buffer room bottom in periphery of the car body, which is surround, is intervally distributed with several lower air inlets diagonally downward, the position in corresponding air-flow buffer ceiling portion is intervally distributed with the enterprising gas port of several inclinations upward, it is linked with spirally inlet air channel between the upper and lower air inlet, check valve is equipped in the spirally inlet air channel；Escape pipe is linked on the interior air-flow concentration chamber, the gas outlet of the escape pipe is towards the outside of car body.The structure design of the utility model is reasonable, by the setting of air-flow buffer room, plays good shunting function to the air-flow in crack, reduces the speed relative to car cab, reduce windage, reduce wind resistance noise.
Description
Technical field：
The utility model is related to elevators fields, relate generally to a kind of lift car.
Background technology：
When elevator is up and down reciprocatingly run in hoistway, gas moment is drastically compressed, between car cab and hoistway
Due to the drastically reduction of flow area, the speed relative to car cab will increase gas at gap suddenly, therefore generate very
Big windage, these resistances are acted on car, just generate windage noise.
Utility model content：
The utility model aim is exactly to provide a kind of lift car, it can be effective to make up the defect of prior art
Reduce windage, reduces noise.
The utility model is achieved through the following technical solutions：
A kind of lift car includes car body, it is characterised in that：It is equipped at the top and bottom of the car body
The air-flow buffer room of one is equipped with interior air-flow concentration chamber, the corresponding gas in periphery of the car body in the air-flow buffer room
The position of stream surge chamber bottom around several lower air inlets diagonally downward are intervally distributed with, corresponds to air-flow buffer ceiling portion
Position is intervally distributed with the enterprising gas port of several inclinations upward, and it is logical to be linked with spirally inlet air between the upper and lower air inlet
Road is equipped with check valve in the spirally inlet air channel；Escape pipe, the escape pipe are linked on the interior air-flow concentration chamber
Gas outlet towards the outside of car body.
A kind of lift car, it is characterised in that：The angle of inclination of the upper and lower air inlet is 20-60 °.
A kind of lift car, it is characterised in that：The angle of inclination of the upper and lower air inlet is 30 °.
When lift car moves down, the fraction in crack is logical by respective spirally inlet air from lower air inlet
Road enters in interior air-flow concentration chamber, then outside interior air-flow concentration chamber discharge car body.But when lift car up moves, folder
Fraction in seam is entered by respective spirally inlet air channel in interior air-flow concentration chamber from enterprising gas port, then from interior gas
It flows outside concentration chamber discharge car body.Effective shunting function played to air-flow in crack in this way, reduces the strong of air-flow in crack
Degree reduces the speed relative to car cab, reduces windage, reduces wind resistance noise.
Due to the setting of check valve, it is ensured that the air-flow of interior air-flow concentration chamber is only discharged from escape pipe.Spirally inlet air is logical
The setting in road increases the flow distance of air-flow, plays the purpose for slowing down air velocity.
The utility model has the advantages that：
The structure design of the utility model is reasonable, by the setting of air-flow buffer room, is played very well to the air-flow in crack
Shunting function, reduce speed relative to car cab, reduce windage, reduce wind resistance noise.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode：
Referring to attached drawing.
A kind of lift car, includes car body 1, and the top and bottom of the car body 1 are equipped with integrated gas
Surge chamber 2 is flowed, interior air-flow concentration chamber 3, the corresponding air-flow buffer in periphery of the car body are equipped in the air-flow buffer room 2
The position of 2 bottom of room around several lower air inlets 4 diagonally downward are intervally distributed with, corresponds to the position in air-flow buffer ceiling portion
It is intervally distributed with the enterprising gas port 5 of several inclinations upward, spirally inlet air channel 6 is linked between the upper and lower air inlet,
It is equipped with check valve 7 in the spirally inlet air channel 6；The pipe of outlet 8, the escape pipe are linked on the interior air-flow concentration chamber
Gas outlet towards the outside of car body.
The angle of inclination of upper and lower air inlet is 30 °.
Claims (3)
