The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. The elevator has the advantages of small floor area, low energy consumption, energy conservation, high efficiency, high lifting speed and the like, and greatly assists the real estate to develop towards the direction of an ultra-high layer. Modern elevators are mainly composed of a traction machine (winch), guide rails, a counterweight, safety devices (such as a speed limiter, a safety gear, a buffer and the like), a signal control system, a car, a hall door and the like, and the elevators are required to be safe and reliable, high in conveying efficiency, accurate in leveling, comfortable to ride and the like.
The tension pulley for the elevator is an important part for elevator safety and mainly comprises a speed governor tension pulley and a compensation chain tension pulley. The main problems of the existing speed limiter tension pulley are that: 1. the elevator cable is arranged on the tension pulley, when the tension pulley is used in an elevator installation space, dust can be accumulated, although the dust can be cleaned and maintained regularly, the accumulation of the dust can bring potential safety hazards to the operation of the elevator, the elevator is stopped in maintenance and maintenance, and inconvenience is caused to the flow of people on a high floor, particularly an ultrahigh floor; 2. the working principle of friction between the elevator cable and the tension pulley makes the tension effect of the tension pulley of the elevator become poor after the tension pulley is used for a period of time, and the tension pulley needs to be replaced periodically.
