These special operators mainly use the standard triangular key of the elevator to open the elevator landing door, and unscrew the triangular lock installed on the upper part of the landing door, and the opening of the landing door is also completed once after unlocking. At the same time, special operators may also step into the hoistway immediately after opening the landing door, because special operators often rely on their own subjective judgments to determine whether the elevator stops at this floor, and the process of opening the door lock is very short, so it is easy Coherently making a series of actions such as opening the door and stepping into the car, which will most likely lead to accidents

Description
technical field [0001] The invention relates to an elevator landing door opening protection device, in particular to a device for providing prompts and safety protection for special operators when they enter the car. Background technique [0002] At present, when an elevator product breaks down, maintenance personnel or elevator management personnel are often required to forcibly open the elevator landing door and enter the pit, car or car roof for maintenance. These special operators mainly use the standard triangular key of the elevator to open the elevator landing door, and unscrew the triangular lock installed on the upper part of the landing door, and the opening of the landing door is also completed once after unlocking. At the same time, special operators may also step into the hoistway immediately after opening the landing door, because special operators often rely on their own subjective judgments to determine whether the elevator stops at this floor, and the proces...
