Abstract

The invention relates to a dual traction drive lift with a manual self-rescue slow descent function. The dual traction drive lift comprises a car, a counterweight, a first fixed pulley, a traction rope, a main traction machine, an auxiliary traction machine, a car movable pulley, a counterweight movable pulley and a traction rope brake mechanism. The first fixed pulley, the main traction machine, the traction rope and the brake mechanism are mounted at the top of a shaftway. The car movable pulley is fixedly mounted at the top of the car, and the counterweight movable pulley is fixedly mounted at the top of the counterweight. The traction rope is of a closed annular structure and is sequentially wound around a traction wheel of the main traction machine, the first fixed pulley, a counterweight fixed pulley, a traction wheel of the auxiliary traction machine and the car movable pulley and then wound back to the traction wheel of the main traction machine. The traction rope brake mechanism comprises a first brake block, a second brake block and a drive device. The first brake block and the second brake block are driven by the drive device to compress or loosen the traction rope on the main traction machine and the auxiliary traction machine. The dual traction drive lift has two kinds of independent drive power, the first power can be switched into the second power when failing, and the situation that people are trapped in the lift due to power failures does not exist.

Description

technical field [0001] The invention relates to a double traction drive elevator with manual self-rescue and slow-down function, belonging to the technical field of elevators. Background technique [0002] The conventional structure of the traction elevator is to drive the car up and down through the traction machine to achieve the purpose of transporting passengers to the designated floor. The traction machine is the only driving power of the elevator, and it is also an important part of life protection for passengers in the elevator. When the only traction machine loses power, passengers can be trapped in the car, or a bigger accident can occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double traction drive elevator with manual self-rescue and slow down function, which has two independent traction powers. An elevator capable of slow descent. [0004] The technical solution of the present invention t...
