Description

An escalator shutdown alarm device

Technical field

This application relates to the technical field of escalator safety assurance equipment, and specifically discloses an escalator shutdown alarm device.

Background technique

Escalators can be seen everywhere in public places. Although escalators provide people with a lot of convenience when they are at work. However, being able to walk on an escalator when it is in the stop position is an important and much-discussed safety issue.

When the escalator stops, the motor is in the stopping device. Without the power of the motor, the brake will be in the holding state. Of course, generally during maintenance or emergency operation, signage will be set up to prevent pedestrians from walking on the escalator when it stops. However, there are still stop devices for power outages and abnormal conditions, as well as some large shopping malls with night movies. After a power outage, moviegoers after watching night movies will also choose to stop on the escalators.

Although the steps of the escalator are relatively stable at this time, the height of the steps of the escalator is generally greater than the height of the steps that people normally walk on, which can easily cause the risk of tripping. When there are too many people traveling on the escalator at the same time, the escalator will If the weight is too heavy and the brake force is insufficient, the ladder will slide, causing pedestrians to fall.

However, because this situation rarely occurs, major shopping malls have not set up restraint orders for stopped escalators, and there are no warning devices or warning devices for pedestrians.

Therefore, in view of this, the inventor provides an escalator shutdown alarm device in order to solve the above problems.
