Abstract
The invention discloses an elevator car top with the function of rotating ladders, which includes an elevator car, and a car top plate, a stepping motor, a rotating shaft, a rotating plate, an inclined frame, a fixed seat, an I electric push rod, a fixed shaft, and a chute , folding frame assembly, II electric push rod, first of all, through the electric rotating plate mechanism, it can facilitate the electric opening of the car top part, which is convenient for the people in the elevator car to escape from the opened power hole; secondly, because of the use of electric push rod and folding frame assembly, so it can be easily extended and opened by the folding frame assembly, realizing the ladder climbing function, and also convenient for shrinking and folding, which is convenient for storage in the unused state and does not interfere with the normal operation of the elevator; finally, because the inclined frame has a certain inclination angle, Not only is it convenient to deploy and use inside the elevator car, but it can also be lifted upwards. In summary, by using the present invention, it is convenient for staff to maintain the elevator car roof, and it is also convenient for people inside the elevator car to escape.
Description
technical field [0001] The invention relates to the technical field of elevator car roof structures, in particular to an elevator car roof with the function of rotating ladders. Background technique [0002] The car is a box-shaped space used by the elevator to carry and transport people and materials. The main structure is generally composed of car floor, car wall, car roof, car door and other main components. The material is generally composed of welded steel frame and stainless steel, and the internal net height of the car should not be less than 2m. [0003] With the rapid development of high-rise buildings, elevators have played a very important role in people's daily life as a kind of vertical transportation manned tool. Therefore, while providing convenience for people, how to make passengers comfortable and safe in a small space has put forward new requirements for elevator design. [0004] According to the above, the current elevator is generally in a safe state ...
