The rotating motor 15 is connected to the upper part of the back end of the support 14. The output end of the rotating motor 15 is fixed with the movable shaft 16. The middle part of the movable shaft 16 is sleeved with the connecting frame 17. The buzzer 110 is sleeved on the lower part of the outer surface of the tension sensor 12.
[0027] The elastic element (such as a bending beam, a coil spring, etc.) of the tension sensor 12 will be deformed after the tension, and the deformation is proportional to the tension, which is used for testing the lifting mass of the tested lifting motor. The lifting rope 13 connects the tension sensor 12 with the tested lifting motor, which is used for testing the force transmission. The bracket 14 is installed on the rotating motor 15, which provides a rotating force. The movable shaft 16 is used in cooperation with the connecting frame 17 to install the tested lifting motor. The buzzer 110 is affected by the built-in control end of the tension sensor 12, and a buzzer is generated for early warning when the detected tension exceeds the rated range.
[0028] The lifting motor test structure further comprises a base 11, the upper end of which is fixed to the lower end of the tension sensor 12, and the lower end of the base 11 is flush with the lower end of the bracket 14.
