A manually controlled wind elevator

Abstract

The invention discloses an elevator with air being controlled manually and relates to the field of elevator manufacturing. The elevator comprises a lift car, a steel wire rope, a counter weight and atraction machine. The lift car comprises a lift car top face, a lift car side face and a lift car bottom face. The lift car top face comprises a top hollow groove. The lift car side face comprises a side hollow groove. The top hollow groove is connected with the side hollow groove through a connecting groove. The top hollow groove is internally provided with an opening / closing plate. The opening / closing plate is connected with the end face at the side, far away from the connecting groove, of the top hollow groove through elastic connecting pieces. The side hollow groove is internally providedwith a push portion. The opening / closing plate is connected with the push portion through a bendable stay bar. A vertical movement groove is formed in the inner surface of the lift car side face and is a vertical strip groove which enables the inner space of the lift car to communicate with the side hollow groove. The lift car top face is further provided with a ventilation portion. Ventilation controllability of the lift car is improved; the lift car can achieve better inner and outer air circulation performance when a great number of passengers are received; and the personal safety problem caused by weak air circulation inside the lift car is avoided.

Description

technical field [0001] The invention relates to the field of elevator manufacturing, in particular to an elevator with manual wind control. Background technique [0002] Traction elevators are widely used in large commercial buildings, office buildings and other areas as people's interlayer transportation equipment. However, the load capacity of traction elevators is a fixed value, and the passenger flow in shopping malls and other buildings has high and low peaks. When the office building encounters the off-duty rush hour or the shopping mall encounters holidays, there will be more passengers taking the traction elevator than usual. At this time, the air flow in the small traction elevator car is not smooth, which will cause The inside of the car is becoming more and more stuffy, which is likely to cause the passengers in the car to suffer from shortness of breath or even faint and shock.
