In a non-leveling zone, a landing door 40 of an elevator is opened, a tool for adjusting a landing door lock in a car is mounted on a car door vane 35 to simulate the extension of the car door vane 35, the car 30 moves in a hoistway, and a worker 50 visually checks the engagement state of the landing door lock 41 and the tool for adjusting the landing door lock in the car. Thus, the operator 50 can observe the engaging state of the car door knife 35 and the landing door lock 41 in the car 30 through the visible area of the bracket 10, and visually adjust and align the landing door lock 41 in the car 30, so that the accuracy of adjustment of the landing door lock 41 is improved, the operation safety is ensured, and the operation efficiency is improved.
In one embodiment, the normal operating condition of the elevator is changed to the service mode before the step S10 of opening the landing door 40 of the elevator at an underbalanced landing. In particular, the service mode may call for a box operation from the electrical box on the ceiling or within the car.
When the elevator is in the inspection mode, the car 30 can move between each landing, and even if the car door 31 of the car 30 is in an open state, the car 30 can move in the hoistway, thereby ensuring smooth completion of adjustment of the landing door lock 41.
In one embodiment, in step S60 of removing the tool for adjusting landing door lock in the car from the door vane 35, the method further includes the following steps: the elevator exits the service mode. Thus, the elevator can normally run in the hoistway, namely when the car 30 is in the non-door-opening area, the car door 31 is in a locking and closing state; when the car 30 is in the door opening area, the car door 31 and the landing door 40 can be opened.
In one embodiment, in step S20 in which the tool for adjusting the landing door lock inside the car is attached to the door vane 35 so as to simulate the extension of the door vane 35, the tool for adjusting the landing door lock inside the car is attached to the door vane 35 outside the landing without attaching the door 31. Thus, the tool is more convenient to install.
In one embodiment, the car 30 moves within the hoistway for a plurality of landing door locks 41, and the landing door locks 41 at each landing are repeatedly adjusted. It should be understood that the tool is not adjusted or changed during the adjustment of the multi-layer door lock 40, so that the tool can be installed and calibrated once to adjust the multi-layer door lock 41, thereby avoiding multiple times of disassembly and assembly, and improving the working efficiency.
