Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Referring to fig. 1 to 3, the escalator full stop device 2 in the present embodiment includes:

a switch base fixed on the truss 1;

the action piece is movably arranged on the switch base;

the travel switch 8 triggered by the action piece sends a signal for controlling the escalator to stop running;

and a pull rope 9 for pulling the action piece to touch the travel switch 8.

In the embodiment, the escalator whole-course stopping device 2 is arranged on a truss, and a maintenance worker of the escalator walkway pulls an action piece through a stretching piece 9 to touch a travel switch 8 to send a signal for controlling the escalator to stop running; the stopping device can be triggered at any position of the escalator to stop the escalator.

The travel switch 8 in this embodiment may be replaced by another sensor, and the sensor is triggered by pulling the operating member through the pull rope 9, or a signal for controlling the escalator to stop running may be sent out, so that the escalator stops running.

In another embodiment, referring to fig. 2 and 3, the actuating member includes a stretching rod 4 connected to the pulling rope 9 and a trigger plate 5 fixed to the stretching rod 4 for triggering the stroke switch 8. The end of the stretching rod 4 is provided with a pull ring 10 for tightening the pull cord. The touch plate 5 is vertical to the stretching rod 4, after the pull rope 9 is pulled, the travel switch 8 is pressed down by the touch plate 5, the switch acts, and the escalator stops running.

In another embodiment, referring to fig. 2 and 3, the switch base comprises a bottom plate 3 fixed with the truss 1 and two supporting plates 7 arranged on the bottom plate 3 at intervals; the two supporting plates 7 are provided with guide holes for the stretching rods 4 to pass through, and the touch plate 5 slides between the two supporting plates 7.

More specifically, the base plate 3 is fixed to the truss 1 by bolts, and the two support plates 7 may be fixed to the base plate 3 by welding, and also the position of the stretching rod 4 is restricted by the support plates 7.

In another embodiment, the switch base is provided with a mounting plate 11 for mounting the travel switch, and the mounting plate 11 is provided with an opening 12 for extending the touch plate 5.
