Abstract

The invention discloses an energy-saving type parallel elevator system. The energy-saving type parallel elevator system is provided with a first elevator car, a first traction rope, a first traction device, a first counter weight, a second elevator car, a second traction rope, a second traction device, a second counter weight and a clutch type transmission mechanism. Each of the first traction device and the second traction device is provided with a drive motor and a brake. The first traction device comprises a first traction wheel and a first center shaft which are mutually fixedly connectedand coaxially arranged. The second traction device comprises a second traction wheel and a second center shaft which are mutually fixedly connected and coaxially arranged. The first elevator car and the first counter weight are hung below the first traction device through the first traction rope, and the second elevator car and the second counter weight are hung below the second traction device through the second traction rope. The clutch type transmission mechanism is connected with the first traction device and the second traction device and provided with a clutch. When the clutch is connected, the linkage relation is formed by the first elevator car and the second elevator car, and the clutch type transmission mechanism can transmit the torque between the first traction wheel and the second traction wheel.

Description

technical field [0001] The invention relates to an elevator system, in particular to a parallel elevator system capable of realizing the goals of energy saving and safety. Background technique [0002] At present, for traditional elevators, each elevator consists of a car, a counterweight, a traction machine, a set of car guide rails, a set of counterweight guide rails, and a set of steel wire ropes. On the wheel, the two ends are respectively connected to the car and the counterweight. ZL2013106959008 discloses an energy-saving traction elevator and its energy-saving method. The elevator system involves the problem that two cars share a balance counterweight. Although it can achieve the purpose of energy saving, it has the problem of wasting building space and materials. Similarly, ZL2013102788749 discloses an energy-saving elevator hoisting system, which also involves the use of counterweights to realize energy-saving elevators, but there is also the problem of wasting bu...
