Example two
How the present application solves the technical problems in real life will be described in detail with reference to the present embodiment.
Firstly, the safety control device is connected with the signal output end of the pressure sensor 8, and the pressure applied by the bearing plates 9 fed back by the 4 pressure sensors 8 can be detected in real time.
After the elevator has been started successfully, the safety protection device first exchanges data with the elevator controller to obtain whether the doors of the elevator car 6 are in a closed state or not and whether the elevator is in a temporary non-running state or not. And collecting the pressure value of the bearing plate 9 fed back by the pressure sensor 8 at the moment, taking the feedback value of the pressure sensor 8 at the moment as the static load of the bearing plate 9, and waiting for the satisfaction of the condition if the condition is not satisfied after data exchange.
After the elevator enters a normal running state, after the static load on the bearing plate 9 is obtained, the protection device immediately enters a safety protection working state, the pressure feedback value of the pressure sensor 8 is collected in real time, and the real-time feedback value of the pressure sensor 8 is compared with the maximum threshold value and the minimum threshold value of the load of the bearing plate 9 respectively.
When the feedback value received by the pressure sensor 8 in real time is between the maximum threshold value and the minimum threshold value, the elevator controller is informed that the elevator is in a normal operation state.
When the feedback value received by the pressure sensor 8 in real time exceeds the maximum threshold value of the load of the bearing plate 9, the elevator controller is informed that the elevator is in an overload state.
When the feedback value received by the pressure sensor 8 in real time is smaller than the minimum threshold value of the load board 9, the elevator controller is informed that the elevator is in a stall condition.
When the elevator is in a normal running state, the electromagnetic force applied to the elevator car 6 and the elevator counterweight 15 is regulated through the interaction of the electromagnetic valve at the elevator car 6 and the counterweight and the electromagnet at the counterweight 24, so that the speed of the elevator in the running process is kept stable under the condition that the weight of the elevator car 6 is continuously changed in the normal running process.
When the elevator is in a stall state, electromagnetic braking force opposite to the moving direction of the elevator car 6 is applied to the elevator car 6 through the closing of an electromagnetic valve by the electromagnetic valve at the elevator car 6 and the electromagnetic valve 23 at the elevator counterweight 15 under the action of the electromagnetic valve at the car and the electromagnet 23 at the car, and the elevator car 6 is stopped at the nearest elevator exit position by combining the real-time position information of the elevator car 6, so that the safety of the elevator is ensured.
When the elevator is in operation, the rope 4 is broken, the counterweight 15 of the elevator cannot balance the weight of the elevator car 6, and the elevator can be decelerated and stopped to the nearest exit position by the damping force between the electromagnet 23 at the car and the guide sliding block 25 at the car.
