Elevator with fireproof structure

Abstract

This utility model relates to the field of elevator car technology, specifically an elevator with a fireproof structure, including a car body. The car body has a protective component inside, which includes a fixing block fixedly connected to the top inner wall of the car body. The fixing block has a trapezoidal groove inside and a sealing groove on its top. This fireproof elevator, by adding the protective component, uses a ceramic fiber board at the innermost layer, which is flexible and heat-resistant for heat absorption. A honeycomb aluminum core panel in the middle increases strength while using the honeycomb structure to insulate heat. A fireproof stainless steel plate enhances structural strength, and a fireproof coating on the outside improves protection. This effectively insulates heat and protects passengers inside the elevator. The trapezoidal block can be detached from the trapezoidal groove by an electric push rod for ventilation, or it can be embedded in the trapezoidal groove to isolate dense smoke. Sealing gaskets and sealing grooves improve airtightness, reduce the entry of dense smoke into the car, extend rescue time, and improve safety.

Description

Technical Field

[0001] This utility model relates to the field of elevator car technology, specifically to an elevator with a fireproof structure. Background Technology

[0002] An elevator car is a box-shaped space used by elevators to carry and transport people and goods. In the event of a fire, flames and thick smoke will enter the elevator shaft, causing the passengers inside the elevator car to be scorched and polluted by the smoke, which will endanger their health and reduce their rescue time.

[0003] In the event of a fire, the elevator car will heat up as the flames rise, scorching the passengers inside. Furthermore, thick smoke will seep into the car and elevator shaft through ventilation openings, suffocating passengers and reducing safety. Utility Model Content
