Problems solved by technology

Generally speaking, the higher the height of the fairing, the easier its shape can be made to reduce wind resistance and noise. Therefore, in order to improve the effect of reducing noise (mute effect), the height of the fairing is often increased, which not only forces the hoistway to be corresponding Heightening the ground, and greatly increasing the overall weight of the car, increasing the load and production cost of the elevator device

no. 1 Embodiment

[0031] figure 1It is a schematic diagram illustrating the elevator apparatus 100 according to the first embodiment of the present invention. The elevator device 100 includes a hoistway 102 , a car 112 , a traction machine, a traction rope 116 , a diversion component 118 , a counterweight 122 , a compensation rope 126 and a diversion component 128 .

[0032] The hoistway 102 provides space for the car 112 to move up and down. The traction machine drives the traction rope 116 through the traction wheel 114 . The car 112 and the counterweight 122 are connected to both ends of the traction rope 116 , and are raised and lowered in the hoistway 102 under the traction of the traction rope 116 . The hoistway 102 is provided with a landing door 108 at a position corresponding to each landing.

[0033] exist figure 1 In , the traction machine is simply represented by the traction wheel 114 instead, and the traction machine is arranged in the machine room above the hoistway 102 . Th...

no. 2 Embodiment

[0063] Figure 10 It is a schematic diagram of the elevator apparatus of the second embodiment provided with the vibration damping device. The elevator device of this embodiment is figure 1 A modified example of the elevator apparatus 100 of the first embodiment is shown. Compared with the first embodiment, the elevator apparatus of this embodiment is provided with a vibration damping device 1002 additionally. Except for this feature, other parts are basically the same as the elevator installation 100 . That is, the elevator device of the present embodiment also includes figure 1 The hoistway 102, the car 112, the traction machine, the traction rope 116, the diversion member 118, the counterweight 122, the compensation rope 126 and the diversion member 128 are shown, and these components are the same as those of the first embodiment. same function. so, Figure 10 Only the structures around the vibration damping device 1002 are briefly shown, and only the technical featur...

no. 3 Embodiment

[0072] Figure 11 It is a schematic diagram of the elevator apparatus of the third embodiment provided with a fairing. The elevator device of this embodiment is figure 1 A modified example of the elevator apparatus 100 of the first embodiment is shown. Compared with the first embodiment, the elevator apparatus of this embodiment is provided with an upper fairing 1102 and a lower fairing 1104 additionally. Except for these features, other parts are basically the same as the elevator device 100 . That is, the elevator device of the present embodiment also includes figure 1 The hoistway 102, the car 112, the traction machine, the traction rope 116, the diversion member 118, the counterweight 122, the compensation rope 126 and the diversion member 128 are shown, and these components are the same as those of the first embodiment. same function. so, Figure 10 Only the structure around the car 112 is briefly shown, and only the technical features different from the first embod...

Abstract

The invention relates to an elevator device. The elevator device comprises flow division components (118, 128) which are arranged on the upper and lower sides of a cage (112) for inducing an air flow, wherein the tops of the flow division components are smaller than the bottoms; the front surfaces of the flow division components towards a landing door (108) are vertical surfaces, left and right surfaces are provided with lateral inclined parts extending from the middles of the tops to the two sides of the bottoms, and the rear surfaces are provided with rear inclined parts extending from the front spaces of the tops towards the rear sides of the bottoms. The flow division component on the upper side of the cage is fixedly arranged at a position on a traction rope (116) with the top facing upwards where the flow division component does not conflict with a traction wheel (114), and the size of the horizontal projection of the flow division component is smaller than a floor rope hole (106) in a machine room floor (104). The flow division component on the lower side of the cage is fixedly arranged on a compensation rope (126) with the top facings downwards. Thus, the elevator device can achieve the effects of air rectification and noise reduction with low cost under the condition that the height of a well is not increased and the load of the elevator device is not greatly increased.

Description

technical field [0001] The invention relates to an elevator device, in particular to an elevator device with an air rectification structure, which can reduce wind resistance and reduce noise when the elevator is running. Background technique [0002] With the high-rise buildings, the speed requirements for elevator installations are also increasing. And along with the raising of elevator speed, the wind resistance that car suffers is more and more bigger, the noise that the air turbulence around the car brings is also more and more loud. These noises can cause discomfort to passengers in the car. In order to reduce such noise, many elevator installations are equipped with fairings above and below the car. In the elevator device disclosed in Japanese Patent Publication No. 6-329372, the second cover of the streamlined fairing composed of curved cover plates 41 to 43 is provided above the car 1, and the second cover of the curved cover plate is provided below the car 1. The...
