Description

An elevator with multiple doors

technical field

The invention relates to an elevator, in particular to an elevator with multiple doors.

Background technique

The vertical elevator has an elevator that runs between at least two vertical or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use the elevator as a The general term for vertical transportation vehicles in buildings, according to the speed, it can be divided into low-speed elevators (below 1 m/s), fast elevators (1-2 m/s) and high-speed elevators (above 2 m/s). Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings today. In 1852, E.G. Otis of the United States developed a safety elevator that was lifted by a wire traction rope. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator.

A common vertical elevator structure as shown in Figure 1, including machine room 1, shaft 2, pit 3, traction machine 4, traction wire rope 5, speed governor 6, car top guide wheel 7, car 8 , safety gear lifting mechanism 9, speed governor steel wire rope 10, tensioning device 11, buffer 12, counterweight frame (cast iron or concrete) 13; On the traction wheel and the guide wheel on the top of the car, the traction machine drives the traction wheel to rotate through its own reducer, and the lift of the car and the counterweight frame is realized by the traction force generated by the friction between the traction wire rope and the traction wheel. To achieve the purpose of transportation. The traction machine and speed limiter monitor and control the speed of the car at any time. When an overspeed situation occurs, that is, when the rated speed of the elevator is 115%, a signal can be sent in time, and then a mechanical action will be generated to make the traction machine lock. If the elevator is still unable to brake, the safety gear installed at the bottom of the car will force the car to stop. The speed limiter is the command sender, and the safety gear is the executor. The combination of the two makes the theory of safe elevator appear. The wire rope of the speed limiter is wound around the speed limiter and connected with the lifting handle of the safety gear to form a speed limiter-safety gear protection device, which plays the role of speed limit protection. The buffer is mainly hydraulic buffer, and the hydraulic buffer (shock absorber) relies on hydraulic damping to buffer and decelerate the objects acting on it to a stop, which plays a certain degree of protection. It is suitable for lifting transportation, elevators, metallurgy, etc. , port machinery, railway vehicles and other mechanical equipment, its role is to prevent hard collisions during the work process to prevent damage to the mechanism.
