A self-locking elevator assembly

Abstract

The invention provides a self-locking type elevator assembly. The self-locking type elevator assembly comprises two door knife assemblies, namely, the first door knife assembly and the second door knife assembly. The first door knife assembly and the second door knife assembly are arranged side by side. The first door knife assembly is arranged at the upper end of a left car door. The second door knife assembly is arranged at the upper end of a right car door. The door knife assemblies are self-locking type door knife assemblies. The first door knife assembly and the second door knife assembly are connected. The self-locking type elevator assembly further comprises two acceleration devices which are arranged at the top ends of a left landing door and a right landing door. The acceleration devices abut against the self-locking type door knife assemblies. The self-locking type door knife assemblies are arranged, and therefore when the car doors arrive at a flat layer, the self-locking structures are automatically opened, and potential safety hazards caused by misoperation when the car doors do not arrive at an assigned point can be effectively avoided; and furthermore, the acceleration devices are arranged and connected with the layer, and therefore when the self-locking structures are opened, the landing doors can be driven to be opened at the same time, and smoothness and safety of opening and closing of the elevator landing doors are improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a self-locking elevator assembly. Background technique [0002] With the increase of modern floors, the use of elevators has brought great convenience to people. But the safety problem of elevator also becomes the problem that people pay close attention to very much. In order to ensure personal safety, the car door is allowed to be opened when the car is in the floor door opening area, while in the non-floor door opening area, the car door should be locked to prevent people from opening the car door from the car. In the prior art, in order to ensure personal safety, it is generally installed in the hoistway to prevent danger when the car door is opened by adding protective barbed wire, but this method has the disadvantages of high cost and long construction period. In order to prevent the elevator car door from being accidentally opened outside the specified area, a car door ...
