A traction elevator with controllable airflow

Abstract

The invention relates to the field of elevator manufacturing, in particular to an airflow controllable traction elevator. The airflow controllable traction elevator comprises a car, steel wire ropes,a counter weight and a traction machine. The car comprises a car top face, a car side face and a car bottom face. The car top face comprises a top empty groove. The car side face comprises a side empty groove. The top empty groove is connected with the side empty groove through a connecting groove. An opening and closing plate is arranged in the top empty groove and is connected with the end faceof the side, away from the connecting groove, of the top empty groove through an elastic connecting part. A pushing portion is arranged in the side empty groove. The opening and closing plate and thepushing portion are connected through a bendable supporting rod. A vertical moving groove is formed in the inner surface of the car side face and is a vertical strip groove communicating the inner space of the car with the side empty groove. A ventilation portion is further arranged on the car top face. Ventilation controllability of the car is improved, the car has better inner and outer air flowability when receiving a large number of passengers, and the personal safety problem generated by poor ventilation in the car is avoided.

Description

technical field [0001] The invention relates to the field of elevator manufacturing, in particular to a traction elevator with controllable air flow. 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.
