Problems solved by technology
Therefore, there is a problem that the lifting time of the elevator is greatly increased, and the service quality for passengers is reduced.
[0009] In addition, when using the method of setting the acceleration or deceleration of the elevator car disclosed in the above-mentioned patent document 2 to be low, it is necessary to set the speed of the elevator so that the longer the lifting distance of the elevator car, the faster the elevator car will be. The smaller the acceleration or deceleration, therefore, before reaching the state of running at the rated speed, the passengers will be in the state of acceleration or deceleration for a long time, so that the burden on the human body during the elevator operation increases, or the operating efficiency of the elevator is reduced. decline

Embodiment Construction
[0034] Embodiments of the present invention will be described below with reference to the drawings.
[0035] figure 1 is a schematic configuration diagram showing an embodiment of the elevator equipment according to the present invention, figure 2 It is an explanatory diagram showing the speed situation of the elevator and the air pressure situation in the elevator car when the elevator descends at the rated speed in two stages.
[0036] like figure 1 As shown, in the elevator equipment of this embodiment, the elevator hoistway 1 is formed inside the super high-rise building, and in the elevator hoistway 1, there are: an elevator car 5 for carrying passengers; a counterweight 11; Hang and connect the elevator car 5 and the sling 10 of the counterweight 11; the hoist, which is composed of a sheave 2 and a motor 3, the sheave 2 is wound with a sling 10, the motor 3 is connected to the sheave 2, and the rope The wheel 2 applies driving force; the elevator control part 4 tha...

The objective of the invention is to provide an elevator device, capable of preventing operation efficiency from reducing greatly and reducing load to a human body greatly. The elevator device is provided with an elevator car and weight counterbalance elevating in an elevation path; a lifting rope; a hoister composed of rope pulleys and a motor for driving the rope pulleys; and an elevator control part for controlling a rotating speed of the motor. The elevator device is also provided with an air pressure detection unit for detecting the air pressure in the elevator car; an air pressure adjusting unit for adjusting the air pressure in the elevator car and an air pressure control unit for controlling the air pressure adjusting unit according to the detection result of the air pressure detection unit, the elevator control part makes the speed of the elevator car to vary among a plurality of different rated speeds in stage, the air pressure control unit drives the air pressure adjusting unit to adjust the air pressure according to the rotating speed of the motor driven by the elevator control part, so as to prevent an ear from choking.
Description
technical field [0001] The present invention relates to an elevator apparatus capable of effectively alleviating ear clogging that is likely to occur in an elevator that has a long lifting distance and operates at a high or super high rated speed. Background technique [0002] As a mobile unit that moves up and down, elevators are widely used in various buildings from low-rise buildings to high-rise buildings. In order to improve the operating efficiency of elevators and shorten the waiting time of elevators, whether at home or abroad , the requirements for high-speed elevators are constantly increasing. Especially recently there have been ultra-high-speed elevators with a speed of more than 1000m. [0003] According to the published research, when the elevator runs at ultra-high speed (generally refers to the speed of more than 600m per minute), the air pressure change per unit time increases, and for the structure of the human ear, due to its inability to The ground adap...
