Emergency escape device for elevator

Abstract

An emergency escape device (1) for elevators is revealed. The emergency escape device (1) is disposed in an elevator system. The emergency escape device (1) includes a motor (11) having an output end (111) linked to a reduction gear set (12). An inner gear (122) of the reduction gear set (12) is engaged with a gear (141) of a rope winder (14) around which a steel cable (2) is wound. Thereby the motor (11) is released automatically from braking when the elevator system loses power and stops due to power outage or mechanical failure. Thus an elevator cabin (3) is pulled downward by gravity and the rope winder (14) rotates to unwind the wound steel cable (2). The steel cable (2) goes down slowly so that the elevator cabin (3) can goes down and stop at the nearest floor, allowing people trapped to come out.

Description

technical field [0001] The present invention relates to an auxiliary escape device for an elevator, in particular to an elevator door that can lower the elevator car and stop at the closest floor when the elevator loses power and cannot move due to factors such as power outages and failures. People who take the elevator can escape smoothly, and the elevator auxiliary escape device with more practical features is added to its overall implementation and use. Background technique [0002] In today's society, due to the narrowness of the land and the dense population, various buildings are generally built higher and higher with more and more floors. Therefore, in order to allow people to easily go up and down the floors and reach the floors they want to go, it is necessary to use them in buildings. Elevator equipment is generally installed; for common elevator equipment, please refer to Figure 5 As shown in the existing three-dimensional structure schematic diagram, it is mainl...

Problems solved by technology

[0003] However, although this elevator equipment can achieve the expected effect of being convenient for users to arrive at the floor they want to go to, it is also found in its actual operation that when various factors such as power outages or malfunctions occur, the elevator equipment will When the power is lost and the elevator car cannot move, the elevator car in operation will stop immediately and will not go up and down again to prevent dangerous situations from happening. However, this design also causes the elevator car to stop between the two floors, not only for It is extremely inconvenient to rescue and get out of trouble, and sometimes limited by the place where the elevator equipment is installed, it is impossible to forcibly pry open the elevator door for rescue. At this time, the users in the elevator car can only wait for the power supply to be restored or the fault to be eliminated Finally, let the elevator car really stop in front of the elevator door on each floor before opening the elevator door and the door of the elevator car to allow the user to leave and get out of trouble. It causes psychological fear, so that there is still room for improvement in the overall implementation and use of the elevator equipment
