A continuous conveyor for transporting persons up and down, while a heavy-duty escalator drive host is currently mainly configured with displacement protection in the horizontal direction. Under the action force of the main driving chain, if the main driving machine generates displacement in the horizontal direction, the unidirectional contact switch acts, and the escalator stops running.

Based on the above, the present inventors found that: under severe working environment, the driving host of the heavy-duty escalator possibly generates horizontal displacement or lifting displacement in the running process and can not provide power for the escalator (the main driving chain falls off), so that the damage to passengers on the escalator is extremely large (the escalator generates backward slip and accelerated descending), and even serious consequences of casualties exist, therefore, in view of the serious consequences, the prior structure is researched and improved, and the heavy-duty escalator driving host bidirectional displacement monitoring device is provided, so that the aim of higher practical value is fulfilled.
