[0042] The escalator cover plate 120 is fixedly installed at the end of the escalator frame 100, and the escalator cover plate 120 is arranged above the step 110. The escalator cover plate 120 can be fixed on the surface of the escalator frame 100 by clamping, threaded connection or the like, so as to facilitate the inspection and maintenance of the step 110 located thereunder by disassembling the escalator cover plate 120 later.

[0044] In an optional embodiment, the monitoring device 200 comprises a mounting assembly 210 and a monitoring assembly 230, the monitoring assembly 230 is rotationally connected with the mounting assembly 210, wherein the upper surface of the mounting assembly 210 is fixedly connected with the escalator cover plate 120, and the lower surface is abutted with the upper surface of the monitoring assembly 230 through a spring 220. For example, the upper surface of the mounting assembly 210 can be fixedly connected with the lower surface of the escalator cover plate 120 through screws or clamping, etc., the monitoring assembly 230 is located below the mounting assembly 210, and the monitoring assembly 230 is rotationally connected with the mounting assembly 210 through a rotating part. The spring 220 is arranged between the mounting assembly 210 and the monitoring assembly 230, the spring 220 can keep the monitoring assembly 230 abutting with the step 110, thereby facilitating the subsequent monitoring of the missing step 110.

[0045] The step 110 in use can include a normal state and a missing state.

[0046] When the step 110 is in the normal state, the normal state is that all steps 110 are normally rotated and no step 110 is missing. In the normal state, the spring 220 is in an extended state, providing downward pressure to the monitoring assembly 230, so that the lower surface of the monitoring assembly 230 is abutted with the upper surface of the step 110, at this time, the monitoring assembly 230 is in a horizontal state, and the protruding part 234 arranged on the upper surface of the monitoring assembly 230 does not contact the induction groove 211 arranged on the corresponding position of the lower surface of the mounting assembly 210, and does not generate any abnormal signal.

[0047] In the normal state, the spring 220 is always in the extended state and always provides downward pressure to the monitoring assembly 230, when the step 110 is in the missing state, the support force of the step 110 to the monitoring assembly 230 disappears, thereby causing the monitoring assembly 230 to rotate relative to the mounting assembly 210 and to be inclined, one end of the monitoring assembly 230 approaches the mounting assembly 210, so that the protruding part 234 in the monitoring assembly 230 approaches the induction groove 211 in the mounting assembly 210, and the protruding part 234 in the monitoring assembly 230 contacts and induces the induction groove 211 in the mounting assembly 210, generating a signal, the cloud controls the elevator to stop running according to the signal, and informs to repair the step 110.

[0048] Therefore, the application provides an escalator step missing monitoring device. The monitoring device 200 is installed below the escalator cover plate 120 and comprises a mounting assembly 210, a spring 220 and a monitoring assembly 230. The mounting assembly 210 is fixedly installed below the escalator cover plate 120. The mounting assembly 210 and the monitoring assembly 230 are connected through the spring 220. The spring 220 is always in an extended state and provides pressure to the monitoring assembly 230, so that the monitoring assembly 230 can abut against the step 110. When the step 110 is in a normal state, the monitoring assembly 230 is in a horizontal state. Once the step 110 is in a missing state, the monitoring assembly 230 will be inclined under the pressure of the spring 220, and the protruding piece 234 will contact the induction groove 211 to generate a signal. The cloud can control the elevator to stop running in time according to the signal. The maintenance personnel can check the step 110 and the monitoring device 200 by only opening the escalator cover plate 120.

The state of the step 110 can be more quickly and accurately acquired, and maintenance can be timely performed.

[0050] In some optional embodiments, a piezoelectric element or an induction coil can be installed in the induction groove 211. When the step 110 is missing, the monitoring assembly 230 is inclined, the protruding piece 234 contacts the piezoelectric element in the induction groove 211 to generate an electric signal, or the protruding piece 234 is a magnetic element and contacts the induction coil in the induction groove 211. The induction coil senses current to generate an electric signal. The signal indicates that the step 110 is in a missing state. The control module 214 acquires the electric signal in the induction groove 211 and uploads the electric signal to the cloud.

The two ends of the rotating shaft 232 are connected through the rotating bracket 235, which can ensure that the wedge-shaped plate 233 keeps balance when abutting against the step 110, and the rotating plate 231 does not tilt when rotating, so that the monitoring result of the missing step 110 is more accurate.
