Description

Technical Field

[0001] This application relates to the technical field of escalators, and in particular to a real-time monitoring trend analysis and warning device for the additional brake of an escalator. Background Art

[0002] An escalator is composed of a chain conveyor with a special structure and two belt conveyors with special structures, with a circulating ladder road, and is a fixed power-driven device used to transport passengers upward or downward at different storeys of a building.

[0003] The additional brake of an escalator is a protection device to prevent the escalator from operating accidentally. Under normal circumstances, the additional brake is in a released state, and the escalator drive system can operate freely. The additional brake is activated in some special situations (such as power failure, main brake failure). Therefore, the operating stability and safety of the escalator mainly depend on the normal working state of these protection devices.

[0004] The additional brake is connected to the drive device of the escalator. Once the additional brake is activated, the braking force will be transmitted to the escalator through this drive device. The additional brake quickly brakes and stops the escalator with a powerful braking force to ensure safety.

[0005] The existing additional brakes mainly include a ratchet, a pawl, and a pawl power unit. The ratchet is installed on the drive device of the escalator. When the additional brake needs to work, the pawl power unit drives the pawl to limit the ratchet to brake the escalator. The existing pawl power units mainly include a pull rod and a pull rod power unit. When the pawl power unit works, the pull rod power unit drives the pawl to move through the pull rod.

[0006] An escalator is an important means of transportation for people to travel. In the actual use process, great attention needs to be paid to the normal working state of the additional brake. However, currently, it is difficult to timely understand the operating state and working conditions of the additional brake only through regular inspection and maintenance of the additional brake, and there are certain potential safety hazards.

[0021] The following further elaborates on this application Figure 1 in conjunction with the accompanying drawings.

[0022] An embodiment of this application discloses a real-time monitoring trend analysis and warning device for an escalator additional brake.

[0023] The existing additional brake 1 mainly includes a ratchet wheel, a pawl, and a pawl power unit. The ratchet wheel is installed on the transmission device of the escalator. When the additional brake 1 needs to work, the pawl power unit drives the pawl to limit the ratchet wheel, thereby braking the escalator. The existing pawl power unit mainly includes a pull rod 11 and a pull rod power unit. When the pawl power unit works, the pull rod power unit drives the pawl to move through the pull rod 11.

[0024] A real-time monitoring trend analysis and warning device for an escalator additional brake includes a measurement component and a data analysis and warning system. The measurement component is used to measure the working stroke of the additional brake 1 in real time and transmit the working stroke data of the additional brake 1 to the data analysis and warning system. The data analysis and warning system pre-stores the data range of the displacement change of the pull rod 11 when the additional brake 1 is working normally. By comparing and analyzing the working stroke data of the pull rod 11 of the additional brake 1 in real time through the data analysis and warning system, when the working stroke of the pull rod 11 of the additional brake 1 is abnormal, the data analysis system gives a warning, so as to facilitate the staff to repair and maintain the additional brake 1 in time and reduce potential safety hazards.

[0025] The measurement component includes a measured part and a measuring part 4.

[0026] The measured part is installed on the pull rod 11, and the measuring part 4 is installed at a position close to the measured part. During the movement of the pull rod 11, the pull rod 11 drives the measured part to move synchronously, and the measuring part 4 monitors the moving distance of the measured part, thereby measuring the moving stroke of the pull rod 11.

[0027] The measured part includes a mounting part 2 and a measured part 3.

[0028] Threads are provided on the pull rod 11, and the mounting part 2 is a number of mounting nuts 21. The number of mounting nuts 21 is threadedly connected to the pull rod 11. In the embodiment of this application, two mounting nuts 21 are provided.

[0029] The measured part 3 includes a mounting plate 31 and a measured plate 32.

[0030] The mounting plate 31 and the measured plate 32 are fixedly connected by a bolt and nut assembly. An installation groove 311 is formed in the mounting plate 31. The installation groove 311 is U-shaped and penetrates through the side of the mounting plate 31. When installing the mounting plate 31 on the pull rod 11, the pull rod 11 is placed inside the installation groove 311 from the side of the mounting plate 31, and the mounting plate 31 is placed between two mounting nuts 21. Then, the mounting nuts 21 are rotated to clamp and fix the mounting plate 31 by the two mounting nuts 21.

[0031] When installing the mounting plate 31 on the pull rod 11, the pull rod 11 is placed inside the installation groove 311 through the side of the mounting plate 31. Thus, the convenience of installing the mounting plate 31 on the pull rod 11 is improved. At the same time, it is also convenient to replace the mounting plate 31.

[0032] The measuring part 4 is a distance measuring sensor. The moving distance of the measured plate 32 is measured by the distance measuring sensor to judge the working stroke of the pull rod 11. In the embodiment of the present application, the distance measuring sensor is a thimble rebound type distance measuring sensor, and the measuring end of the thimble rebound type distance measuring sensor abuts against the measured plate 32. The distance measuring sensor is electrically connected to the data analysis and early warning system, and the measuring part 4 transmits the data model of the measured pull rod 11 to the data analysis and early warning system for analysis.

[0033] The implementation principle of the real-time monitoring trend analysis and early warning device for the additional brake of the escalator in the embodiment of the present application is as follows: when installing the mounting plate 31 on the pull rod 11, the pull rod 11 is placed inside the installation groove 311 from the side of the mounting plate 31, and the mounting plate 31 is placed between two mounting nuts 21. Then, the mounting nuts 21 are rotated to clamp and fix the mounting plate 31 by the two mounting nuts 21. And the distance measuring sensor is installed at a position close to the measured plate 32. During the movement of the pull rod 11, the pull rod 11 drives the measured part 3 to move synchronously through the mounting member 2. At this time, the measuring part 4 measures the measured part 3 in real time to determine the moving stroke of the pull rod 11, and transmits the moving stroke data of the pull rod 11 to the data analysis and early warning system. The data analysis and early warning system analyzes the moving stroke data of the pull rod 11 to judge whether the additional brake 1 works normally.

[0034] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
