In this embodiment, the DZS series electromagnetic de-energization brake sold by Anhui Juxing Electromagnetic Brake Co., Ltd. is selected. The principle is : When the electromagnetic brake is energized, the electromagnetic suction immediately attracts the armature and compresses the spring, and the brake disc is disengaged from the armature and can rotate freely. When the power is cut off, the brake armature loses its electromagnetic attraction, and the spring pushes the armature to press the brake disc to achieve the braking effect under the action of friction torque. The safety device 5 is a safety lock, which can ensure that the equipment is locked on the safety wire rope when the tower elevator falls beyond the set speed due to accidents or emergencies by detecting the running speed of the equipment. The working principle of the safety lock is: the wire rope passes through the safety lock, passes through the lock block and two friction wheels, when the moving speed of the wire rope is less than the set speed (generally 22m/min), the lock block is in the open state, the wire rope passes smoothly, and the friction The wheel drives the speed measuring mechanism (flying block) to rotate. Once the speed exceeds the set speed (the set speed is set by designing the fast rotation speed), the flying block will trigger the trigger lever when rotating due to the centrifugal force, so that the trigger lever will rotate. , so as to drive the pole to rotate, so that the pole is separated from the limit gap on the lock block support plate, and the lock block support plate blocked by the support plate rotates under the action of the torsion spring, so that the lock block clamps the wire rope and stops the wire rope. move.
