The invention relates to a mechanical anti-reversal device for an escalator, which can effectively solve the problem of anti-reversal of the escalator and ensure the safety of the escalator. The structure is that the guide rail includes a first guide rail and a second guide rail, the slider includes a first slider and a second slider, the pawl includes a first pawl and a second pawl, and the ratchet includes a first ratchet and a second ratchet. The first ratchet and the second ratchet have opposite ratchets and are installed in parallel on the rotating shaft of the escalator, and rotate together with the rotating shaft. The bottom plate is fixed on the fixed frame of the escalator. A moving handle, a first spring support plate, a first guide rail, a first pawl positioning plate, a second pawl positioning plate, a second guide rail and a second spring support plate are successively installed on the sliding plate from left to right. Escalators installed in shopping malls, supermarkets, stations, airports and other places have the advantages of simple structure, high reliability, and not affected by the control system.
Description
technical field [0001] The invention relates to machinery, in particular to a mechanical escalator anti-reverse device. Background technique [0002] As a tool for transporting people, escalators are widely used in crowded places such as shopping malls, supermarkets, stations, and airports. The reliability of the escalator itself plays a vital role in ensuring the safety of human life. At present, most escalator manufacturers pay attention to the reliability of escalators when designing, and design multiple sets of safety protection devices and mechanical and electrical interlocks to prevent accidents. Nevertheless, under the influence of factors such as long-term overload, poor working environment, inadequate maintenance, human error, and non-compliance with regulations, escalator accidents have occurred frequently. The most common failure is that the escalator is running suddenly reversed. Once the escalator is reversed during operation, due to the effect of inertia, pa...
