Ventilation structure of elevator roof

Abstract

The invention belongs to the technical field of elevator ventilation equipment, in particular to a ventilation structure for an elevator ceiling, comprising an elevator car body, two through holes are opened on the top inner wall of the elevator car body, and the two through holes are respectively welded and fixed There are exhaust pipes and air intake pipes, and horizontal bars are welded and fixed in the exhaust pipes and air intake pipes, vertical shafts are rotatably installed on the two horizontal bars, and ventilation fan blades are welded and fixed on the tops of the two vertical shafts. The bottom ends of the two vertical shafts are all welded and fixed with first bevel gears, and the inner walls of the side where the exhaust pipe and the air intake pipe are close to each other are provided with rotating holes, and the same rotating shaft is installed in the two rotating holes. The invention has high practicability and can keep the elevator in constant circulation with the outside air while the elevator is working normally, thereby ensuring the fresh air inside the elevator car, and at the same time, it is convenient to replace the filter cover for filtering the air.

Description

technical field [0001] The invention relates to the technical field of elevator ventilation equipment, in particular to a ventilation structure for an elevator ceiling. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take people or carry goods, there are also steps, and the tread plate is installed on the crawler belt to run continuously, commonly known as escalator or moving walkway, The fixed lifting equipment serving the specified floors. The vertical elevator has a car that runs between at least two vertical rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary regardless of its driving mode. , using the elevator as a general term for vertical transportation in a building. Now the vertical elevator car roof usually includes ventilation ducts or ventilation channels...

AI Technical Summary

Problems solved by technology

[0003] However, the ventilation mechanism of the elevator cannot keep the air inside the elevator car and the outside air in convection, and at the same time, the filter screen used to filter the intake air cannot be replaced in time, so that it cannot continue to enter the elevator car after a long period of use. The air in the elevator car cannot be replaced, and the air entering the elevator car cannot be filtered, which affects the cleanliness of the air inside the elevator car.
