Abstract

The invention provides a high speed ladder car door wind proofing and noise reduction structure. The high speed ladder car door wind proofing and noise reduction structure comprises a convex sheet arranged on a butt joint face of a lift car door body and a sealing piece arranged on the other lift car door body in a manner of corresponding to the convex sheet; the convex sheet comprises a sealing part in contact with the sealing piece, a contact face is arranged on the surface, in contact with the sealing piece, of the sealing part, and a continuous contact boss is arranged on the contact face; a heating wire and a cooling pipe are paved in the sealing piece, an elastic part is arranged on the sealing piece and the contact face of the convex sheet, an elastic convex part expanding along with increase of the temperature and shrinking along with decrease of the temperature is arranged on the surface of the elastic part, and the elastic convex part extrudes the contact boss and a gap of the contact boss under the expanding state. By means of the high speed ladder car door wind proofing and noise reduction structure, the gap between the two lift car door bodies is controlled through expanding and shrinking of the elastic convex part of the sealing piece, and the high speed ladder car door wind proofing and noise reduction structure has the beneficial effects of being good in sealing effect, capable of achieving control automation, long in service life, good in sealing temperature and the like.

Description

technical field [0001] The invention belongs to the field of elevators, in particular to a windproof and noise-reducing structure for a car door of a high-speed elevator. Background technique [0002] When the existing high-speed elevator reaches a running speed of more than 4 m / s, due to the closed setting of the elevator shaft, the airflow quickly enters and exits the car from each gap in the car, causing the passengers in the car to feel uncomfortable. The elevator car usually has a sealing structure such as a labyrinth buckle between the door and the vertical plate to prevent the airflow from entering the car and keep the air pressure in the car stable. However, in the gap of the car door, the sealing structure is different. A novel windproof and noise reduction structure is designed in this application. Contents of the invention [0003] In view of this, the present invention aims to propose a high-speed elevator car door windproof and noise reduction structure to so...
