Description of the embodiments

The present application is described in further detail below in conjunction with figures 1-5.

The embodiment of the application discloses a device for detecting a backup brake for suspension approaching equipment.

Referring to fig. 1, the related art backup brake operates on the principle of: when the inner ratchet 174 rotates counterclockwise, the roller 175 is disengaged, so that the inner ratchet 174 can rotate freely, thereby realizing the lifting function. When the inner ratchet 174 rotates clockwise, it will drive the brake ring 176 to rotate together, generating a resistive torque controlled by the torque limiter 173 such that the resistive torque of the entire brake ring 176 is greater than the gravitational torque of the loading module 2, generating a mechanical brake.
