Vertical elevator high in safety

Abstract

The invention discloses a vertical elevator high in safety. The vertical elevator comprises a shaft, a car arranged in the shaft, a safety device arranged on the car and an elevator door device matched with the car. A service port is formed in the car. An elevator calling button is arranged on the shaft. The elevator door device comprises an inner door structure for opening and closing the car, anouter door structure for opening and closing the shaft and a synchronous movement structure for achieving transmission fit between the inner door structure and the outer door structure. According tothe vertical elevator, by arranging the inner door structure and the outer door structure, in the operation process of the elevator, the shaft and an elevator door cannot be opened, and personal safety of passengers is guaranteed. By arranging the synchronous movement structure, an inner door and an outer door can be synchronously opened, opening and closing are convenient, the phenomenon that opening and closing of the inner door and the outer door are delayed is avoided, and it is guaranteed that daily use by people is convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to a vertical elevator with high safety.
