Description

Technical Field

[0001] The present invention relates to the field of escalators, and in particular to a real-time monitoring system for the health status of an escalator. Background Art

[0002] An escalator is a fixed electric-driven device used to transport passengers upward or downward. Electric escalators are generally inclined. When pedestrians stand on the automatically moving steps at one end of the escalator, they will be automatically taken to the other end of the escalator. The steps will remain level all the way. The escalator has handrails on both sides that move synchronously with the steps for users to hold. The advantage of an escalator is that it runs continuously and can quickly transport a large number of passengers to their destinations. In addition, escalators have a high transport capacity and can operate in any weather and time conditions, making them an important part of public transportation.

[0003] There are still certain drawbacks in the use of the real-time monitoring system for the health status of escalators in the existing technology. When a traditional escalator fails, it can usually only stop the escalator. Pedestrians may still step on the steps or climb the stairs without paying attention. Since the cause of the failure is unknown, this behavior may cause the steps to be missed or internal parts to fall off, resulting in pedestrian injuries, posing a major safety hazard. Summary of the invention

[0004] The purpose of the present invention is to provide a real-time monitoring system for the health status of an escalator, so as to solve the problem proposed in the above background technology that when a traditional escalator fails, the escalator can usually only be stopped, and pedestrians may still step on the steps or climb the stairs without paying attention. Since the cause of the failure is unknown, this behavior may cause the steps to be missed or internal parts to fall off, resulting in pedestrian injuries and a major safety hazard.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a real-time monitoring system for the health status of an escalator, comprising an escalator truss, wall panels are provided on both sides above the escalator truss, first steering sprockets are provided at the upper and lower ends of the interior of the escalator truss, the first steering sprocket is connected to the second steering sprocket through a transmission chain, the second steering sprocket is arranged on one side of a machine base, a driving motor is provided above the machine base, and the second steering sprocket is connected to the driving motor through a gear transmission, a motor forward and reverse monitoring sensor head is provided on the inner side of the first steering sprocket, a driving chain break sensor head is provided on the outer side of the transmission chain, a lower cover plate is provided on the top of the lower end of the escalator truss, an upper cover plate is provided on the top of the upper end of the escalator truss, a plurality of anti-slip notches are provided on the surface of the upper cover plate, a limit frame is provided at the surrounding positions below the upper cover plate, a notch is provided on one side of the bottom surface of the upper cover plate, a lifting lug is provided inside the notch, and an electric telescopic rod is provided at the lower position inside the lifting lug.

[0007] In a further embodiment, a triangular reinforcement sheet is provided on the bottom surface of the limit frame, and the limit frame is connected to the escalator truss by welding.

[0008] In a further embodiment, the top end of the electric telescopic rod is slidably connected to the lifting ear via a coordinating slider and a coordinating slide groove, and the electric telescopic rod is connected to the coordinating slider by rotation.

[0009] In a further embodiment, the lifting ear is connected to the notch by welding, and the cross-section of the notch is set to a trapezoidal structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the invention, the upper cover is configured as a flippable structure, which enables the upper cover to have two functions: one is to seal and protect the top of the escalator frame, and the other is to block pedestrians and serve as a warning. When the escalator fails, the upper cover can be flipped outward by electric control to form a vertical structure, which can block the entrance of the escalator, prevent pedestrians from climbing the ladder, and avoid danger to pedestrians. When maintenance personnel have not arrived at the scene, the safety of the scene can be guaranteed to avoid injuries.

[0016] 2. Both the upper cover and the lower cover are equipped with gravity sensors and sound and light alarm devices; when there are no pedestrians on the cover, the sound and light alarm reminds passengers not to approach the escalator cover area, and at the same time, the cover is flipped outward to block the escalator entrance; when there are pedestrians on the cover, the sound and light alarm reminds passengers to exit the cover area backwards, and after the passengers leave the cover, the cover is flipped outward to block the escalator entrance; infrared sensor counters are set at both ends of the wall panel, one is an adder and the other is a subtractor. When going up or down, one side rises, and when the counter on the other side is 0 and the cover pressure sensor is 0, the cover is raised to ensure safety. BRIEF DESCRIPTION OF THE DRAWINGS
