Abstract

The invention discloses a small door lock safety system for an elevator landing door frame, comprising: a landing door panel, a first unlocking mechanism is arranged inside the landing door panel; a landing door device, the landing door device is arranged on the landing door panel above, the landing door device is provided with a landing door lock, and the first unlocking mechanism locks and cooperates with the landing door lock; the landing door frame, the landing door frame is arranged on the side of the landing door panel A door cover is movable on the door frame of the landing door, and a second unlocking mechanism is provided on the inner side of the door cover. The door cover and the door frame of the landing door are locked and matched by the second unlocking mechanism. The second unlocking mechanism is provided with a connecting device, and an electric switch is arranged in the door frame of the landing door, and the connecting device is used to conduct the contacts of the electric switch. The invention ensures that when the maintenance personnel are located in the hoistway, the elevator cannot run normally all the time, thereby ensuring the safety of the maintenance personnel.

Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to a small door lock safety system for elevator landing door frame. Background technique [0002] With the growth of the national economy and the development of the aging trend of my country's population, coupled with the increase in the country's attention to national life, the domestic installation of elevators is about to usher in a large market. Compared with the traditional elevator, the installation of the elevator often encounters the situation that the depth of the pit is too small or the height of the top floor is not enough, which will make the maintenance personnel unable to obtain enough space to avoid danger when they are located in the hoistway. In response to this problem and the national standard GB / T 28621 -2012 regulations, it is necessary to take measures to ensure the safety of maintenance personnel in the shaft when the depth of the pit is insuffi...
