Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a car safety door with a detachable frame. Background Art

[0002] Elevators are special equipment for carrying people. People's first concern is of course its safety and reliability. In real life, elevators often encounter emergencies due to power outages, malfunctions and other factors. How to ensure the safety of passengers and provide timely rescue in emergencies has always been a key topic in elevator design.

[0003] During the research process of this topic, many achievements have been made, one of which is the car safety door, that is, safety doors are set on both parallel elevators. When one of them fails and stops, the staff enters the other elevator and stops the car to the same height, and enters the faulty elevator through the safety door for rescue; the ordinary car safety door is to open a rectangular hole on the surrounding wall, and use square tubes to weld a frame on the back of the rectangular hole, and then connect the safety door and the frame with hinges; this design is based on the surrounding wall. Due to the material of the surrounding wall plate, there are certain restrictions on the size of the safety door. Under the condition of meeting the national standard requirements, the size cannot be too large, otherwise the strength of the surrounding wall where the safety door is located will be affected. Therefore, there are many restrictions on the design and decoration of the elevator, and the small size of the safety door also affects the speed of personnel rescue, which is very fatal in an emergency. At the same time, the integrated safety door is not convenient for transportation due to the volume problem, and welding also increases the construction cost; in addition, when the width and height of the safety door need to be adjusted, the existing safety door frame needs to be replaced as a whole, and the adjustment cost is high.
