Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and more particularly to a weight-measuring car structure of a flat-energy elevator. Background Art

[0002] There are many types of elevators today, but the principles are basically the same: the car and counterweight are connected by traction cables, and the operation of the elevator is achieved by controlling the cables.

[0003] Safe and energy-saving elevators are referred to as safe energy elevators. The car structure of safe energy elevators is different from that of traditional elevators.

[0004] Patent document CN201821057949.5 discloses an elevator, comprising a car top plate, a car side plate and a car bottom plate fixedly connected in sequence, and also comprising a ventilation motor installed in the elevator top plate, a pressure sensor fixedly arranged in the elevator bottom plate and a single-chip microcomputer electrically connected to the ventilation motor. The pressure sensor is used to detect the pressure on the car bottom plate and output a weight measurement signal. After receiving the weight measurement signal, the single-chip microcomputer controls the speed of the ventilation motor through a PWM signal. When passengers enter the elevator, the pressure sensor sends a weight measurement signal to the single-chip microcomputer, thereby controlling the PWM signal output by the single-chip microcomputer to adjust the average voltage transmitted by the driving power supply to the ventilation motor, thereby realizing control of the ventilation intensity in the elevator. As the number of passengers in the elevator increases, the weight measurement signal changes, and the average voltage of the ventilation motor is increased through the PWM signal, thereby increasing its speed, improving the ventilation capacity, and avoiding the problem of poor ventilation when there are many people in the elevator.

[0005] The aforementioned elevator uses a pressure sensor within the elevator floor to detect weight. However, the elevator floor is relatively large, and inaccurate measurements can occur when passengers are not standing directly above the pressure sensor. This means that the traditional elevator car weight measurement method, when applied to a flat-energy elevator, can lead to inaccurate measurements. A search has failed to identify any existing technology that addresses this technical issue. Therefore, a unique car structure tailored to the characteristics of a flat-energy elevator was necessary.

[0033] In this embodiment, the gravity measuring mechanism includes two stress strain gauges 8 located at the top and bottom of the third load-bearing beam 3, respectively. A gravity difference is formed between the two stress strain gauges 8 for detection, i.e., the load in the car is obtained based on the difference between the two stress strain gauges 8. The stress strain gauges 8 are located on the central axis of the third load-bearing beam 3, and the two stress strain gauges 8 are on the same vertical line, which can ensure the accuracy of the car load measurement.
