Traction System of Passenger Elevator
Traction system is mainly composed of traction machine, traction wire rope, guide wheel. The traction machine is composed of a motor coupling, a brake, a reducer, a base, a traction sheave and the like, and is a power source of a passenger elevator. Two ends of the traction wire rope are respectively connected with a car and a counterweight device Seat on the room), relying on the friction between the wire rope and traction sheave rope groove to drive the passenger elevator; guide wheel's role is to separate the car and the weight of the device distance, the use of complex winding type can also increase the drag Capability. Guide wheel mounted on the traction frame or on the beam. When the rope rope rope ratio greater than 1, in the car and the counter-frame should be additional anti-rope wheel. The number of return wheels can be 1, 2, or even 3, which is related to the traction ratio.
The guidance system consists of guide rails, guide shoes and guide rails. Its role is to limit the car and counterweight can only be along the rail for lifting movements. The guide rail is fixed on the guide rail bracket; the guide rail bracket is a component that supports the guide rail and is connected with the hoistway wall; the guide shoe is mounted on the car and the counterweight frame and cooperates with the guide rail to force the car and the counterweight to obey the upright direction.
Door system consists of car door, landing door, open the door machine, linkage agencies, door locks and other components. The car door agency in the car entrance, by the door leaf, the door rail frame, door boots and knives and other components; Lienzhe clubs in the landing, by the door leaf, door rail rack, door boots and door lock devices and unlock devices; Open the door agency in the car, the car door and landing door power source.
