The invention discloses a novel underneath passage type added elevator, and belongs to the technical field of added elevators of existing buildings, the added elevator comprises an elevator shaft, a lift car, a traction machine, a counterweight and a guide wheel set, the lift car and the counterweight are both located in the elevator shaft, the traction machine is arranged above the elevator shaft, a machine-room-free structural form is adopted, and the guide wheel set is arranged above the elevator shaft. The traction machine is connected with the lift car and the counterweight through steel wire ropes, the steel wire ropes are hung on the two sides of the traction wheel and penetrate through the pulley block, and the pulley block is used for adjusting the traction ratio between the lift car and the counterweight. The invention provides a novel underneath channel type added elevator arrangement mode, a 1: 1 or 2: 1 traction ratio suspension mode is adopted on the car side, and a 2: 1 or 4: 1 traction ratio suspension mode is adopted on the counterweight side, so that the counterweight stroke only occupies half of the total stroke, the sectional area of a bottom layer elevator shaft can be greatly reduced, the floor space of the bottom layer can be reduced, and the service life of the elevator is prolonged. Therefore, a rescue channel can be reserved in an old community, and a more flexible elevator arrangement mode can be provided in the field of elevator installation.
本发明公开了一种新型的下置通道式加装电梯,属于既有建筑加装电梯的技术领域,所述加装电梯包括电梯井道、轿厢、曳引机、对重、导向轮组,所述轿厢及对重均位于电梯井道内,所述曳引机设置在电梯井道上方,采用无机房结构形式,所述曳引机通过钢丝绳连接轿厢及对重,所述钢丝绳悬挂与曳引轮两侧并穿过滑轮组,所述滑轮组用于调整轿厢与对重之间的曳引比。本发明提供一种新型的下置通道式加装电梯布置方式,轿厢侧采用1:1或2:1的曳引比悬挂方式,对重侧采用2:1或4:1的曳引比悬挂方式,这样对重的行程只占据总行程的一半,可以大大缩小底层电梯井道的截面积,减小底层占地空间,以便老旧小区留出救援通道,在加装电梯领域能提供更加灵活的电梯布置方式。
