The utility model installs a protective net 1 under the passenger-side step to prevent passengers from falling between two running steps and suffering shear injuries due to broken or missing steps. The utility model installs a linkage trigger component 2 between the protective net 1 and the passenger-side step. When the step breaks and sinks to press the wire rope or the passenger steps on the wire rope due to missing steps, the safety switch is triggered to stop the escalator or moving walkway in time, avoiding safety accidents and reducing personal and property losses. The utility model is an independent safety protection device that can be installed on any type of escalator or moving walkway, has good adaptability, and can be widely promoted.

[0021] Specifically, in this embodiment, the linkage trigger assembly 2 includes a linkage rope 21, a safety switch 22, and a spring 23. The linkage rope 21 is arranged along the step width from the lower level of the escalator or moving walkway to the upper level of the escalator. The linkage rope 21 is fixed at one end on the lower level of the escalator or moving walkway, and the linkage rope 21 at the upper level of the escalator or moving walkway is connected via the spring 23. The safety switch 22 is connected to the spring 23. The safety switch 22 is electrically connected to the control system of the escalator or moving walkway. When the linkage rope 21 is pulled by an external force, the spring 23 is stretched, triggering the safety switch 22 to stop the escalator. It should be noted that to ensure monitoring sensitivity, the spacing between two adjacent linkage ropes 21 can be appropriately reduced. The linkage rope 21 is pulled from the lower level to the upper level, fixed at the lower level, and tightened by a spring 23 at the upper level. When the linkage rope 21 is pulled by an external force, the safety switch 22 is triggered to stop the escalator, avoiding safety accidents and reducing personal and property losses.

[0022] Specifically, in this embodiment, the protective net 1 is a metal net. It should be noted that the metal net can be other similar supporting devices or structures installed in the gap between the passenger side steps and the left and right connecting beams of the truss.

[0023] Specifically, in this embodiment, the linkage rope 21 is a steel wire rope. It should be noted that the linkage rope 21 can also be a linear object made of other materials.

[0024] In summary, the present invention installs a metal mesh beneath the passenger-side steps to prevent shear injuries to passengers who fall between two running steps due to broken or missing steps. A wire rope, linked to a safety switch 22, is installed between the metal mesh and the passenger-side steps. If a broken step sinks and presses against the wire rope, or a passenger steps on the wire rope due to a missing step, the safety switch 22 is triggered, immediately stopping the escalator or moving walkway, thus preventing accidents and minimizing loss of life and property.
