Elevator for modification of old building

Abstract

The invention relates to the field of elevator equipment, in particular to an elevator for modification of an old building. The elevator comprises an elevator lift car, elevator holes and a driving mechanism, and further comprises floor cover plates and a control mechanism which ascends and descends along with the elevator lift car to control automatic opening and closing of the floor cover plates. The control mechanism comprises first cam plates arranged on the upper surfaces of the floor cover plates, first rollers arranged at the lower ends of the side walls of the elevator lift car and used for being matched with the first cam plates on the corresponding sides, second cam plates arranged on the lower surfaces of the floor cover plates and second rollers arranged at the upper ends of the side walls of the elevator lift car and used for being matched with the second cam plates on the corresponding sides. The first cam plates and the second cam plates are distributed parallel to an elevator lift car door and located in different vertical planes. According to the elevator for modification of the old building, an elevator shaft is not added, the elevator holes in a passage are automatically opened and closed in the operation process of the elevator, and safety accidents prone to happening as the elevator holes are always opened are avoided.

Description

technical field [0001] The invention relates to the field of elevator equipment, in particular to an elevator used for renovation of old buildings.
