Description

Technical Field

[0001] At least one embodiment of the present utility model relates to the technical field of escalators, and in particular to a monitoring system for an additional brake friction disc of an escalator and an escalator. Background Art

[0002] Escalators are fixed electric-driven devices used to transport passengers upward or downward between different floors of a building. They are widely used in public places such as shopping malls and stations.

[0003] An escalator consists of a drive unit, steps, handrails, brakes, and an auxiliary brake. The drive unit drives the steps. The main brake is used to stop the escalator in an emergency. The auxiliary brake is an additional safety device, providing additional security in the event of main brake failure or other emergency situations. The auxiliary brake automatically activates to slow or stop the escalator when the escalator speed exceeds a set safety limit. During escalator operation, the friction disc of the auxiliary brake rotates synchronously with the escalator. When the auxiliary brake is activated, the friction disc stops rotating and quickly brakes all moving parts, effectively stopping the friction disc and the moving parts synchronously. However, there are also cases where the friction disc stops, relying on the friction force generated by the friction disc to stop the moving parts. This causes the friction disc and the moving parts to move out of sync, and the rotation status of the friction disc and the moving parts cannot be monitored in a timely manner, thus affecting the safety performance of the escalator.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

For example, “a system having at least one of A, B, or C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc.

[0049] During escalator operation, the friction disc of the auxiliary brake rotates synchronously with the escalator. When the auxiliary brake is activated, the friction disc stops rotating and quickly brakes the moving parts, effectively stopping them synchronously. However, there are also cases where the friction disc remains stationary, relying on the frictional force generated by the disc to stop the moving parts. This creates a situation where the friction disc and the moving parts are not synchronized, and the rotation of the friction disc and the moving parts cannot be effectively monitored, thus compromising the safety of the escalator.

[0050] Figure 1 Schematically shows a side view of a monitoring system according to an embodiment of the present disclosure; Figure 2 yes Figure 1 Enlarged view of point A in the middle; Figure 3 yes Figure 1 Enlarged view of point B in the middle.

[0051] The embodiment of the present disclosure provides a monitoring system for an escalator auxiliary brake friction disc, such as Figure 1 、 Figure 2 and Figure 3As shown, the monitoring system includes a main body 1, a drive mechanism 2, a first detection mechanism 3, a friction disc 4, a second detection mechanism 5 and a controller (not shown in the figure). The drive mechanism 2 is mounted on the main body 1. The first detection mechanism 3 is configured to detect the rotation of the drive mechanism 2 and output an operating signal 6 indicating that the drive mechanism 2 is rotating normally. The friction disc 4 is mounted on the drive mechanism 2 and rotates with the drive mechanism 2. The second detection mechanism 5 is configured to detect the rotation of the friction disc 4 and output a first signal 7 indicating that the friction disc 4 is rotating normally or a second signal 8 indicating that the friction disc 4 has stopped rotating. The controller outputs an alarm signal in response to the operating signal 6 output by the first detection mechanism 3 and the second signal 8 output by the second detection mechanism 5.

[0052] According to an embodiment of the present disclosure, when the first detection mechanism 3 outputs an operating signal 6, it indicates that the drive mechanism 2 is rotating normally. At this time, when the second detection mechanism 5 outputs a second signal 8, it indicates that the friction disc 4 has stopped rotating and the friction disc 4 and the drive mechanism 2 are not moving synchronously. In response to the operating signal 6 and the second signal 8, the controller outputs an alarm signal to warn that the friction disc 4 and the drive mechanism 2 are not moving synchronously, so as to remind relevant personnel to take measures, thereby improving the safety performance of the escalator.

[0053] In detail, the first detection mechanism 3 and the second detection mechanism 5 can be any one of an electromagnetic sensor, a photoelectric sensor, and a Hall sensor. It can be understood that the first detection mechanism 3 and the second detection mechanism 5 are set according to actual needs.

[0054] It should be noted that the first detection mechanism 3 detects the rotation of the drive mechanism 2. When the first detection mechanism 3 outputs an operating signal 6, the drive mechanism 2 rotates normally, indicating that the escalator is in normal operation. At this time, the second detection mechanism 5 detects the rotation of the friction disc 4. When the second detection mechanism 5 outputs a first signal 7, it indicates that the friction disc 4 rotates normally and rotates synchronously with the drive mechanism 2. When the second detection mechanism 5 outputs a second signal 8, it indicates that the friction disc 4 stops rotating and does not move synchronously with the drive mechanism 2.

[0055] The controller can output an alarm signal in response to the operating signal 6 and the second signal 8, which can promptly alert relevant staff that the friction disk 4 and the drive mechanism 2 are not moving synchronously, thereby reminding relevant staff to take measures such as braking the escalator and troubleshooting to improve the safety performance of the escalator.

[0056] In an exemplary embodiment, Figure 1As shown, the drive mechanism 2 includes a drive assembly 21, a rotating shaft 22, and a transmission assembly 23. The drive assembly 21 is mounted on the main body 1. The rotating shaft 22 is rotatably mounted on the main body 1. The friction disc 4 is mounted on the rotating shaft 22 and rotates with the rotating shaft 22. The transmission assembly 23 is mounted between the drive assembly 21 and the rotating shaft 22 and is configured to rotate the rotating shaft 22 when driven by the drive assembly 21.

[0057] It should be noted that the drive mechanism 2 drives the escalator steps. The drive assembly 21 can be a motor, a motor and reducer assembly, or the like, without limitation. The transmission assembly 23 can be a sprocket transmission assembly 23, a pulley transmission assembly 23, or the like. The friction disc 4 of the auxiliary brake is mounted on the rotating shaft 22. During normal operation, the friction disc 4 rotates synchronously with the rotating shaft 22. When the auxiliary brake is activated, the friction disc 4 stops rotating, and the friction force generated by the friction disc 4 stops the movement of the drive mechanism 2. The friction disc 4 and the drive mechanism 2 are no longer synchronized.

[0058] In an exemplary embodiment, Figure 1 As shown, the transmission assembly 23 includes a driving wheel 231, a driven wheel 232, and a transmission member 233. The driving wheel 231 rotates when driven by the drive assembly 21. The driven wheel 232 is mounted on the rotating shaft 22 and is coaxial with the rotating shaft 22. The transmission member 233 is mounted on the driving wheel 231 and the driven wheel 232 and can drive the driven wheel 232 and the rotating shaft 22 to rotate when driven by the driving wheel 231. The transmission member 233 can be a sprocket, a pulley, etc., which is not limited here.

[0059] Figure 4 A side view of a driver flywheel according to an embodiment of the present disclosure is schematically shown. Figure 5 The diagram schematically shows an operation signal diagram according to an embodiment of the present disclosure.

[0060] In an exemplary embodiment, Figure 2 and Figure 4 As shown, the drive mechanism 2 also includes a driver flywheel 24. The driver flywheel 24 is mounted on the drive assembly 21 and rotates with the output shaft of the drive assembly 21. The driver flywheel 24 is provided with a plurality of through-holes 241, which are evenly spaced in the circumferential direction around the output shaft of the drive assembly 21. The first detection mechanism 3 faces any one of the plurality of through-holes 241. Specifically, the first detection mechanism 3 corresponds to the circular ring formed by the plurality of through-holes 241.

[0061] According to an embodiment of the present disclosure, when the drive assembly 21 drives the rotating shaft 22 via the transmission assembly 23, the drive flywheel 24 rotates synchronously. During the rotation of the drive flywheel 24, the first detection mechanism 3 sequentially corresponds to the through hole 241 or the drive flywheel 24, thereby generating an operating signal 6 in which high-level pulse signals and low-level pulse signals regularly alternate, indicating that the drive flywheel 24 and the drive mechanism 2 are rotating normally, and that the drive mechanism 2 is driving the escalator normally.

[0062] In an exemplary embodiment, Figure 1 and Figure 3 As shown, a plurality of brake blocks 41 are provided on the friction disc 4 , and the plurality of brake blocks 41 are evenly spaced in the circumferential direction around the rotation axis of the friction disc 4 , and the second detection mechanism 5 faces any one of the plurality of brake blocks 41 .

[0063] In an exemplary embodiment, Figure 1 As shown, a plurality of brake blocks 41 are provided on the front side of the friction disc 4 and are evenly spaced in the circumferential direction around the rotation axis.

[0064] In an alternative exemplary embodiment, the brake pads may also be arranged on the circumferential side of the friction disk and distributed evenly in the circumferential direction around the rotation axis.

[0065] Figure 6 A first signal diagram according to an embodiment of the present disclosure is schematically shown.

[0066] In an exemplary embodiment, Figure 3 and Figure 6 As shown, the second detection mechanism 5 outputs a first feedback signal 71 when facing the brake block 41, and outputs a second feedback signal 72 when facing the friction disk 4, and outputs a first signal 7 when the first feedback signal 71 and the second feedback signal 72 appear regularly and alternately.

[0067] According to the embodiment of the present disclosure, during the synchronous rotation of the friction disc 4 and the rotating shaft, the second detection mechanism 5 faces the brake block 41 and the friction disc 4 in sequence. When the second detection mechanism 5 faces the brake block 41, it outputs the first feedback signal 71, and when it faces the friction disc 4, it outputs the second feedback signal 72. Therefore, Figure 6 As shown, when the friction disc 4 rotates synchronously with the rotating shaft, the first feedback signal 71 and the second feedback signal 72 appear regularly and alternately, thereby outputting the first signal 7.

[0068] Figure 7 A second signal diagram according to an embodiment of the present disclosure is schematically shown. Figure 8 A second signal diagram according to another embodiment of the present disclosure is schematically shown.

[0069] In an exemplary embodiment, Figure 7 and Figure 8 As shown, when the first feedback signal 71 and the second feedback signal 72 appear irregularly and alternately, the second detection mechanism 5 outputs the second signal 8 .

[0070] In detail, Figure 1 and Figure 3 As shown, when the friction disc 4 cannot rotate synchronously with the shaft, the friction disc 4 may stop rotating. At this time, the second detection mechanism 5 is facing the brake block 41 or the friction disc 4. Figure 7 As shown, when the second detection mechanism 5 is facing the brake block 41 and the friction disc 4 stops rotating, the second detection mechanism 5 continuously outputs the first feedback signal 71. When the second detection mechanism 5 is facing the friction disc 4 and the friction disc 4 stops rotating, as shown Figure 8 As shown, the second detection mechanism 5 continuously outputs the second feedback signal 72. Continuously outputting the first feedback signal 71 or the second feedback signal 72 does not allow for regular alternation of the first feedback signal 71 and the second feedback signal 72. The second detection mechanism 5 outputs the second signal 8, indicating that the friction disc 4 has stopped rotating and that the friction disc 4 and the drive mechanism 2 are not moving synchronously. This allows for timely feedback of the motion state of the friction disc 4.

[0071] According to an embodiment of the present disclosure, when the drive mechanism 2 rotates normally, the first detection mechanism 3 outputs an operating signal 6, indicating that the escalator is operating normally under the drive of the drive mechanism 2. The second detection mechanism 5 detects the operating status of the friction disc 4 in real time. When the friction disc 4 stops rotating, the first feedback signal 71 and the second feedback signal 72 appear irregularly and alternately, and the second detection mechanism 5 outputs a second signal 8. In response to the operating signal 6 and the second signal 8, the controller outputs an alarm signal to warn that the friction disc 4 and the drive mechanism 2 are not moving synchronously, so as to remind relevant staff to take measures to improve the safety of the escalator.

[0072] In an exemplary embodiment, the monitoring system further includes controlling the driving mechanism 2 to stop rotating when the controller outputs an alarm signal.

[0073] In an exemplary embodiment, the alarm signal can be an audible alarm such as a sirens or sirens; a visual alarm such as an indicator light or a display screen; a vibration alarm; an electronic alarm such as a computer pop-up window prompt or a mobile application push notification. There is no limitation here and it is set according to actual needs.

[0074] According to the embodiments of the present disclosure, the controller outputs an alarm signal to warn that the friction disc 4 and drive mechanism 2 are not operating synchronously, thereby prompting relevant personnel to take timely action. Furthermore, when the controller outputs the alarm signal, it stops the drive mechanism 2 by cutting off the power supply or using any other control method, thus applying emergency braking. This can more quickly stop the operation of the drive mechanism 2 and reduce the degree of damage caused by friction between the friction disc 4 and the drive mechanism 2, thereby improving the safety performance of the escalator.

[0075] In an exemplary embodiment, the monitoring system further includes a controller that outputs a safety signal in response to the operation signal 6 output by the first detection mechanism 3 and the first signal 7 output by the second detection mechanism 5 .

[0076] In an exemplary embodiment, first detection mechanism 3 outputs an operating signal 6, indicating that drive mechanism 2 is operating normally. Second detection mechanism 5 outputs a first signal 7, indicating that auxiliary brake friction disc 4 is rotating normally. In response to operating signal 6 and first signal 7, the controller outputs a safety signal, allowing personnel to monitor the operating status of the escalator and auxiliary brake friction disc 4 in real time.

[0077] According to a second aspect of the present disclosure, an escalator is further provided, comprising the monitoring system and steps as described above. The steps rotate under the drive of a driving mechanism 2 .

[0078] According to the monitoring system for the friction disc of an escalator auxiliary brake and the escalator provided by the present disclosure, when the first detection mechanism 3 outputs an operating signal 6, it indicates that the drive mechanism 2 is rotating normally. At this time, when the second detection mechanism 5 outputs a second signal 8, it indicates that the friction disc 4 has stopped rotating and the friction disc 4 and the drive mechanism 2 are not moving synchronously. In response to the operating signal 6 and the second signal 8, the controller outputs an alarm signal, thereby monitoring the rotation of the friction disc 4 and the drive mechanism 2 in real time, and promptly alerting relevant personnel so that timely measures can be taken, thereby improving the safety performance of the escalator.

[0079] The above describes embodiments of the present invention. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although each embodiment has been described separately above, this does not mean that the measures in each embodiment cannot be used in combination to advantage. The scope of the present invention is defined by the appended claims and their equivalents. Without departing from the scope of the present invention, those skilled in the art may make various substitutions and modifications, which should all fall within the scope of the present invention.
