Title: OVERWEIGHT ALARM DEVICE FOR ELEVATOR CAR
Abstract:
An overweight alarm device for an elevator car comprises a car frame (3) and a pressure balance (10). A pulley bracket (2) and a pulley (1) are disposed on the top of the car frame (3). A track (4) is disposed on a side surface of the car frame (3). The pressure balance (10) is disposed on the bottom of the car frame (3). An upper bottom plate (5), an upper bottom plate contact (6), a lower bottom plate contact (7), a spring (8) and a lower bottom plate (9) are disposed on the pressure balance (10). A built-in circuit (11) is disposed in the lower bottom plate (9). A power supply module (12), a master control circuit (13), a storage module (14), a gravity computing module (15), an output module (16), a pressure sensor (17), a display module (18) and an alarm module (19) are disposed on the built-in circuit (11). A principle similar to an electronic scale is used on the device; when the gravity in the car reaches a set value, the built-in circuit (11) is switched on, and the alarm device gives out a signal indicating overweight, so as to remind a user of paying attention to safety.
