Lower ventilating structure of elevator car

Abstract

A lower ventilation structure for the cage of elevator has a wall plate, the reinforcing ribs on the back of wall plate, a base board at the low end of wall plate and the ventilating seam between wall plate and base board.

Description

technical field [0001] The invention relates to a ventilation structure of an elevator car, in particular to a ventilation structure arranged at the lower part of the elevator car. Background technique [0002] With the increasing development of the elevator industry, a new standard GB 7588-2003 has been put forward in the elevator industry, in which clause 8.16 stipulates the ventilation requirements of the car. Ventilation holes must be provided at the lower part of the car, and the effective area of ​​the upper and lower ventilation is not large. It should be less than 1% of the effective area of ​​the car. [0003] The current ventilation of the elevator car is generally achieved by setting ventilation holes on the upper part of the car to achieve air convection with the shaft, and there is no ventilation hole on the lower part of the car. The lower part of the car is designed to directly connect the car wall with the skirting board, and ma...

Problems solved by technology

However, this method needs to modify the sheet metal processing line. In addition, opening holes in the car wall is not only required to be beautiful, but also to prevent passengers in the car from peeking into the hoistway through the holes as much as possible. mold, the cost is too high, and there is a lot of trouble in the transformation of the existing elevator
