Embodiment Construction
[0019] like figure 1 and figure 2 As shown, a kind of escalator provided by the present invention or moving walk pedal fracture protection device comprises conductive metal rope 2, spring 6, conductive metal plate 3, relay 4, maintenance switch 11 and DC power supply 10; Said conductive metal rope 2 Installed under the escalator or moving walk pedal 1 and parallel to the running path of the pedal 1, one end of the conductive metal rope 2 is fixed on the insulating material of the truss, and the other end is connected to the spring 6 fixed on the truss through the insulating material , the spring 6 is tensioned, so that the conductive metal rope 2 is tensioned and suspended without grounding. The conductive metal rope here is preferably a steel wire rope 2, especially a thin steel wire rope. The advantages of the steel wire rope are high strength, light weight, stable work, and not easy The whole root is broken. Of course, other conductive metal materials, such as silver met...

The invention relates to an escalator or moving sidewalk pedal rupture protection device. When an escalator or moving sidewalk pedal is ruptured to collapse, the pedal downwards presses an electric conducting metal rope; as a spring has tension, the electric conducting metal rope is contacted with an electric conducting metal plate; a relay coil negative wiring terminal is conducted with a negative pole of a direct-current power supply by the electric conducting metal rope and the electric conducting metal plate; at this time, a coil of a relay is electrified to immediately act, so that a normally closed point of the relay is cut off, and a safety loop is immediately cut off to realize sudden stop of an escalator or moving sidewalk; and meanwhile, after the coil of the relay is electrified to act, a normally open point of the relay is closed, the coil of the relay is always electrified, the normally closed point of the relay is always located in an off state, and the safety loop is always located in an off state. The device has the advantages of capability of realizing whole monitoring, sensitive detection and difficult failure.
Description
technical field [0001] The invention relates to a protection device, in particular to a safety protection device for broken pedals in the field of escalators or moving walks. Background technique [0002] There are frequent accidents where escalators or moving walkways in shopping malls and supermarkets collapse, causing injuries to passengers’ legs and feet, and even causing death by involving passengers in escalators or moving walkways. When designing escalators or sidewalks, major elevator manufacturers have installed a series of protective devices such as pedal lower limit, pedal drop and pedal loss. But these devices can not stop the moving walkway at the first time when the accident occurs, most of them need to come off or collapsed pedal to run to the position where the protective device is installed to stop the operation. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a...
