Embodiment 1
[0051] see Figure 1-10 , an elevator car with an emergency opening and closing mechanism, comprising a car floor 10, a transmission belt 11 is installed at the front end of the car floor 10, a pair of mounting plates 1 located at the rear side of the transmission belt 11 are fixedly connected to the front end of the car floor 10, and the mounting plate 1. The front end is fixedly equipped with a driving rod 2. The driving rod 2 is a prior art. Those skilled in the art can select a suitable type of driving rod 2 according to actual needs. For example, the model is: the driving rod 2 of LAP25. The upper end of the driving rod 2 is connected with a The pressing assembly 3 matching the transmission belt 11, the front end of the mounting plate 1 is connected with the cutting assembly 4 located at the lower side of the pressing assembly 3, and the left side of the cutting assembly 4 is connected with the linkage assembly 5 matching the driving rod 2; please refer to Figure 4 , the...
Embodiment 2
[0062] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to Figure 8 with Figure 9 , the upper end of the car floor 10 is fixedly installed with the main controller, and the front end of the installation plate 1 is fixedly installed with the sub-controller, the output end of the sub-controller is electrically connected with the driving rod 2 through the wire, and the input end of the sub-controller is connected with the main controller through the wire electrical connection. Through the mutual cooperation between the main controller and the sub-controllers, the driving rod 2 can effectively interact with the door mechanism of the elevator car, assist the use of the door mechanism, facilitate the maintenance o...
Embodiment 3
[0065] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 3 and embodiment 1 is: please refer to Figure 10 , a method for using an elevator car with an emergency opening and closing mechanism, comprising the steps of:
[0066] S1. When the elevator car fails and the door of the elevator car cannot be opened normally;
[0067] S2. The rescuer starts by controlling the driving rod 2, so that the pressing assembly 3 moves, acts on the transmission belt 11, and increases the tension of the transmission belt 11;
[0068] S3. Then the rescuer tries to control the normal opening of the elevator car door;
[0069] S4. If the elevator car door does not open normally, the control drive lever 2 continues to start, and drives the pressing component 3 and th...
