High-speed silent lift car for lift

Abstract

The invention relates to a high-speed silent life car for a lift. The high-speed silent lift car comprises a connecting lift car, wherein the connecting lift car comprises a movable fairing which consists of a fixed shield, multiple steering engines and a movable deformation cover; the fixed shield is arranged on the connecting lift car; the multiple steering engines are evenly distributed on thefixed shield; the movable deformation cover is formed by inserting and overlapping a plurality of fan-shaped plates; the lower end of each fan-shaped plate is fixed on the corresponding steering engine; each steering engine consists of a steering engine base, a balance wheel and a driving mechanism; the steering engine bases are fixed on the fixed shield; the balance wheels are arranged in the steering engine bases; the upper edges of the balance wheels and the lower ends of the fan-shaped plates are fixed; and the balance wheels are connected with the driving mechanisms. By adopting the technical scheme in the invention, when the lift car runs in different directions at a high speed, the shape of the lift car is correspondingly changed, thus reducing the advancement resistance, completely eradicating or lowering generation of eddy currents, ensuring interference-free running of the lift car for the lift, having no noise, and achieving the purpose of a silent lift car.

Description

technical field [0001] The invention relates to an elevator car, in particular to a high-speed elevator silent car. Background technique [0002] In the prior art, in order to reduce the wind resistance of the elevator car, such as figure 1 As shown in , most of them are connected to the upper and lower ends of the car 2, that is, the arc-shaped fairing 1 is arranged on the top and bottom of the car, the traction rope 3 is connected to the top of the car 2, and the accompanying cable 4 is connected to the car. the bottom of the box; figure 2 As shown in , when the elevator runs upwards at high speed, the airflow 5 flows along the outer wall of the connecting car 2, which can reduce wind resistance, but a large number of eddy currents 6 will be generated at the bottom of the connecting car, and the eddy current 6 is very close to the accompanying cable 4, Make the accompanying cable 4 vibrate violently, and then cause the whole car to vibrate. Since the elevator operates i...

[0002] In the prior art, in order to reduce the resistance of the wind, the elevator car, such as figure 1 As shown in , most of them are connected to the upper and lower ends of the car 2, that is, the arc-shaped fairing 1 is arranged on the top and bottom of the car, the traction rope 3 is connected to the top of the car 2, and the accompanying cable 4 is connected to the car. the bottom of the box; figure 2 As shown in , when the elevator runs upwards at high speed, the airflow 5 flows along the outer wall of the connecting car 2, which can reduce wind resistance, but a large number of eddy currents 6 will be generated at the bottom of the connecting car, and the eddy current 6 is very close to the accompanying cable 4, Make the accompanying cable 4 vibrate violently, and then cause the whole car to vibrate. Since the elevator operates in two directions, when the elevator runs downward at high speed, the principle is the same as above, and it will also vibrate the traction rope 3 violently. And then make the whole car vibrate
