Abstract
The patent discloses a locking device for two-dimensional rotating equipment. The locking device comprises a base, a direction rotation ejector device, a locking mechanical arm, an electromagnetic brake, a locking shafting and an unlocking torsional spring. The locking device is mounted on an end face of a two-dimensional rotating equipment base, pitching, rotating and locking of the two-dimensional rotating equipment are achieved through the top end of the locking mechanical arm, and locking of direction rotation is achieved through the ejector device. Braking of the locking shafting can be achieved through the power-off braking function of a power-loss electromagnetic brake, and the locking device is enabled to maintain the locking of the two-dimensional rotating equipment. When the locking device is needed for relieving the braking of the two-dimensional rotating equipment, the electromagnetic brake is powered on and the braking is relieved. Under the act of the torsion of the unlocking torsional spring, the locking mechanical arm rotates around the locking shafting and rotates away from the working range of the two-dimensional rotating equipment. When the electromagnetic brake is powered off again, braking torque enables the locking device to maintain an unlocking state.
