An energy-saving elevator

Abstract

The invention relates to the field of elevators, in particular to an energy-saving elevator. The energy-saving elevator comprises lift shafts, a car lift and acounterweight block, a supporting frame is arranged at the top ends of the lift shafts, a tractive unit, a tractive wheel and a generator are successively arranged on the supporting frame, an output shaft of the tractive unit is connected with one side of the tractive wheel, the other side of the tractive wheel is connected with the generator through a rotating shaft, the output shaftof the tractive unit, the tractive wheel and the rotating shaft are all coaxially arranged, a tractive belt is arranged on the tractive wheel, one end of the tractive belt is connected with the counterweight block, the other end of the tractive belt is connected with the car lift, gear guiding rails are uniformly formed in the inner walls, on the two sides of the car lift, of the lift shafts from top to bottom, anti-falling devices matched with the gear guiding rails are symmetrically arranged at the top of the car lift, and a sensor for sensing the speed of the car lift is arranged at the top of the car lift. According to the energy-saving elevator, security is high, and the generator can be driven to generate electric energy and supplies power for the partial functions of the elevatorwhile the elevator is rising or falling.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an energy-saving elevator. Background technique [0002] With the continuous development of my country's economy, high-rise residential buildings and office buildings continue to emerge. What follows is the continuous increase in the number of elevators in our country and the continuous expansion of the scale of elevator use. Elevators are widely used in the national economy and life. As a means of transportation running vertically in high-rise buildings, elevators are inseparable from people's daily life. At the same time, currently used elevators, internal facilities such as their lighting systems and ventilation systems basically adopt the mode of external power supply. In addition, the elevator needs to stand by and work for a long time, so the huge waste of power resources caused by the external power supply mode is obvious. [0003] And when the elevator in the market is in oper...

AI Technical Summary

Problems solved by technology

Although the elevator has light, strong and rigid elevator suspension ropes, it is suitable for transporting people or goods, but the elevator does not have an energy-saving design, which will cause a huge waste of power resources in actual use and increase the cost of the manager. No anti-falling device is designed. When the suspension rope breaks or other parts fail to cause the elevator car to fall, the elevator has no good protection measures and the safety is low.
