As the name suggests, the elevator shaft light plays a lighting role in the elevator shaft, ensuring that the staff can clearly see the situation in the shaft when repairing and inspecting the elevator, avoiding unnecessary safety hazards. At present, the elevator shaft light is controlled by the double switch of the machine room distribution box and the pit.

Once these signals are detected, the system will automatically trigger the lighting equipment in the shaft to ensure that there is sufficient illumination inside the shaft so that maintenance personnel can clearly view and operate, greatly improving operation safety.

[0045] In this embodiment, Figure 1 As shown, the shaft maintenance light module includes the following lights connected in series: L1 shaft maintenance light, L2 shaft maintenance light, L3 shaft maintenance light, ..., Ln shaft maintenance light.

[0046] When the positive terminal of the relay coil collects the elevator maintenance signal received by the signal access module, the relay coil is energized and its corresponding normally open contact is closed. At this time, a circuit is formed in the hoistway maintenance light module to light up.

[0047] Specifically, the first relay module includes: a first relay coil KM1 and a first normally open contact K1 corresponding thereto; the negative terminal of the first relay coil KM1 is connected to a negative power supply, and the positive terminal is connected to a corresponding first signal access module; one end of the first normally open contact K1 is connected to a positive power supply AC220V, and the other end is connected to a positive terminal of a shaft inspection light module; the negative terminal of the shaft inspection light module is connected to a negative common terminal in a PCB board;

[0051] The positive power supply is a 220V AC power supply.

[0052] The shaft inspection light triggering device proposed by the utility model is mainly used in the following working conditions:

[0053] 1. During elevator maintenance operations, when there are workers working in the machine room and on the car top at the same time, in order to ensure safety, the operator in the machine room will put the elevator in emergency electric mode. In this state, the elevator will generate a clear "machine room emergency electric" signal (recorded as X1). At this time, the first relay coil KM1 collects the "machine room emergency electric" signal, KM1 is energized and attracted, and then its corresponding first normally open contact K1 is changed to a normally closed state. In this way, the shaft inspection lights L1 to Ln in the shaft form a closed loop, so that the power is turned on and starts to emit light. In this way, whenever the elevator is in emergency electric mode, the shaft inspection lights in the shaft will be automatically activated to ensure that all working areas in the shaft are adequately illuminated, effectively preventing misoperation and safety accidents caused by poor visibility, and greatly improving the safety and efficiency of elevator maintenance operations.

[0054] 2. When there is only one worker on the car top and the floor is high, it is extremely inconvenient to go to the machine room to turn on the shaft inspection light. When the worker on the car top puts the elevator in the inspection mode, the elevator system will generate a car top inspection signal X2. At this time, the second relay coil KM2 collects the inspection signal, KM2 is energized and attracted, and then the corresponding second normally open contact K2 is changed to a normally closed state. This change will also cause the shaft inspection lights L1 to Ln to form a closed loop, so that the shaft lighting system is started, providing sufficient lighting to ensure the safety of the workers on the car top.

[0055] 3. When there is only one person working in the pit, and it is inconvenient to run to the machine room to turn on the shaft maintenance light on the high floor, the operator in the pit puts the elevator in maintenance mode, and the elevator system generates a pit maintenance signal X3. When the third relay coil KM3 collects this pit maintenance signal X3, KM3 is energized, and the corresponding third normally open contact K3 becomes normally closed. As a result, the shaft maintenance lights L1 to Ln will also form a loop, thereby lighting up the work, ensuring that there is sufficient lighting in the pit area and ensuring the safety of the operators.

[0056] 4. When the elevator fails, the elevator system will automatically generate a fault status signal X4. At this time, when the fourth relay coil KM4 collects the signal, KM4 is energized and attracted, and then the corresponding fourth normally open contact K4 is changed to a normally closed state, and all the well maintenance lights L1 to Ln in the well are connected in series to form a closed circuit, thereby starting and emitting sufficient light to illuminate the inside of the well.

[0057] The utility model embodies the characteristics of humanity and intelligence, so that under various working conditions, whether it is working in the machine room, on the car top or in the pit, the shaft lighting can be automatically activated through the corresponding working mode setting, thereby improving work efficiency and safety.
