Abstract

The invention relates to the technical field of elevators, and discloses a magnetic safety assembly for reducing gravitational potential energy during elevator stall falling. The magnetic safety assembly comprises a cable; a cable pipe is fixedly connected to the outer side of the cable; a speed reducing mechanism is movably connected to the outer side of the cable pipe; a gripper is movably connected to the top of the speed reducing mechanism; and a balance layer is fixedly connected to the inner side of the gripper. According to the magnetic safety assembly for reducing the gravitational potential energy during elevator stall falling, induced current is generated and transmitted to an electrode plate through transmission of a circuit, so that a coil on the outer side of the electrode plate is electrified, and when the gripper moves outwards, the speed reducing plate at the bottom of a connecting rod moves in the electrified coil; furthermore, in the moving process, according to the Lenz's law, it can be known that the speed reducing plate can generate the eddy current effect when the coil moves, and movement of the gripper is limited according to the coming and leaving refusing principle, so that the falling potential energy of the cable is consumed, and the elevator stall protection level is improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a magnetic safety component for reducing gravitational potential energy when an elevator stalls and falls. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take people or carry goods, there are also steps, and the tread plate is installed on the crawler belt to run continuously, commonly known as escalator or moving walkway, Wherein the vertical elevator has a car running between at least two vertical rigid guide rails. [0003] However, existing vertical elevators seldom have a special machine room. Most vertical elevators are installed inside the elevator shaft and adopt a straight-through structure. The straight-through structure is convenient for construction and people’s daily use, but there are When the elevator suddenly stalls, the tension cable lacks the...
