Embodiment Construction
[0010] figure 1 It is a schematic diagram of the structure of the device. The device is equipped with a pressure sensor 9 at the bottom of the car 8. The pressure sensor 9 can generate an induction signal according to the change of the load of the car 8. It is equipped with a wireless transmitter 7, which can transmit its signal through wireless transmission. The device 7 is transmitted to the wireless receiving device 4 of the counterweight control mechanism 6, and the counterweight control mechanism 6 controls the manipulator 1 placed on the corresponding layer on the counterweight side according to the judgment of the signal generation. By moving the mechanical arm and moving the counterweight weight 2, the number of counterweight weights 2 can be increased or decreased to realize the weight change of the variable counterweight car 3 and achieve the balance between the car 8 and the variable counterweight car 3, thereby Realize the up and down movement of the elevator.
