Description

Technical Field

[0001] The present application relates to the technical field of personnel transportation, and in particular to a braking system for an escalator and a moving sidewalk, and personnel transportation equipment. Background Art

[0002] Currently, the braking systems of moving walkways and escalators mostly use band brakes, equipped with microswitches and smoke detectors to monitor brake electromagnet operation and smoke emissions. When a faulty elevator brake electromagnet causes the brake band to not fully disengage from the brake disc when opening, friction between the disc and the brake band pads during operation can cause the brake pad rubber to heat up abnormally, generating an unpleasant odor and accompanied by smoke.

[0003] However, in actual use, the smoke alarm device cannot detect the abnormal temperature rise of the brake rubber in the first time. The smoke alarm device can only detect the smoke of the brake rubber after the temperature is too high. The monitoring sensitivity is low, and there is a lack of monitoring of whether the brake status is good, which cannot meet the management needs of pre-emptive fire safety prevention. Utility Model Content

[0004] In view of the fact that the braking system in the above-mentioned related technologies cannot monitor the brake status well and cannot meet actual needs, the present application aims to propose a braking system and personnel transportation equipment for escalators and moving walkways. The braking system is equipped with an intelligent temperature monitoring device to ensure that the braking system is within a reasonable temperature range during normal operation. When encountering an abnormal situation, the temperature monitoring device can be used to stop the operation in time to solve the technical problems existing in the above-mentioned related technologies.

[0005] To this end, a first aspect of the present application is to propose a braking system for an escalator and a moving walkway.

[0006] A second aspect of the present application is to provide a personnel transport device.

[0007] In view of this, according to a first aspect of the present application, a braking system for an escalator or moving sidewalk is proposed, wherein the braking system for an escalator or moving sidewalk includes a brake disc disposed on a drive shaft of the escalator or moving sidewalk; a brake belt extending around the brake disc, with both ends of the brake belt fixed to fixed parts of the escalator or moving sidewalk; and a temperature monitoring device for monitoring the temperature of the brake belt; wherein the temperature monitoring device is connected to a safety control circuit of the escalator or moving sidewalk.

[0008] During operation, when the temperature monitoring device detects that the temperature of the brake belt is greater than the first temperature threshold, the temperature monitoring device controls the escalator or moving sidewalk to stop running through the safety control circuit; when the temperature monitoring device detects that the temperature of the brake belt is less than the second temperature threshold, the temperature monitoring device controls the escalator or moving sidewalk to resume operation through the safety control circuit; the first temperature threshold is greater than or equal to the second temperature threshold.

[0009] In this way, when encountering abnormal situations, braking can be performed in time through the temperature monitoring device to avoid the occurrence of serious accidents such as subsequent smoke caused by excessive temperature, thereby ensuring that the braking system is within a reasonable temperature range during normal operation. When encountering abnormal situations, the impact of equipment failures on operating services is reduced, and the quality of operation and maintenance is improved.

[0010] In practical applications, the first temperature threshold may be appropriately greater than the second temperature threshold to leave a safety margin, thereby avoiding frequent starts and stops.

[0011] In some technical solutions, optionally, the temperature monitoring device includes: a temperature sensing probe for monitoring the temperature of the brake belt; and a temperature controller connecting the temperature sensing probe and the safety control circuit.

[0012] Specifically, the temperature probe is used to monitor the temperature of the brake belt; the temperature controller is connected to the temperature probe and the safety control circuit, and is used to receive the temperature data monitored by the temperature probe and compare it with the preset temperature threshold. When the temperature is greater than the first temperature threshold, a stop operation signal is sent to the safety control circuit; conversely, when the temperature is less than the second temperature threshold, a resume operation signal is sent to the safety control circuit.

[0013] In some technical solutions, optionally, the temperature controller includes a display panel for displaying temperature data monitored by the temperature sensor.

[0014] In this technical solution, the display panel displays real-time temperature data monitored by the temperature probe. This allows maintenance personnel to visually observe the brake belt temperature without relying on other tools or equipment for measurement. This facilitates fault diagnosis and maintenance work. It also helps maintenance personnel analyze system operating conditions, predict potential problems, and develop appropriate maintenance plans.

[0015] In some technical solutions, the thermostat optionally includes a temperature adjustment button that works in conjunction with the display panel, allowing operators to adjust the temperature threshold. This can address the impact of different operating environments, load conditions, or seasonal changes on the brake system temperature, thereby helping to improve the reliability and applicability of the brake system.

[0016] In some technical solutions, a temperature sensor can be optionally installed on the surface of the brake band. This allows for rapid detection of temperature changes in the brake band, ensuring real-time and accurate temperature data and avoiding errors that may be introduced by indirect measurement methods. When the brake band temperature exceeds a threshold, the thermostat can react quickly, preventing potential safety risks.

[0017] In some technical solutions, the temperature probe is optionally adhered to the surface of the brake band, which makes it easy to disassemble and maintain.

[0018] In the above technical solution, optionally, the temperature sensing probe is fixed to the surface of the brake belt through thermal conductive silicone.

[0019] Thermally conductive silicone has excellent adhesion, thermal conductivity, and heat resistance. It not only firmly fixes the temperature probe to the surface of the brake belt, but also forms a good heat conduction path between the two, thereby helping to improve the accuracy and real-time performance of the measurement. At the same time, thermally conductive silicone also has a certain degree of elasticity, which can protect the temperature probe to a certain extent.

[0020] In some technical solutions, the braking system of the escalator and moving walkway optionally includes an alarm device connected to a temperature monitoring device. Thus, when the temperature monitoring device detects that the temperature of the brake belt exceeds a threshold, the alarm device can promptly sound an alarm, thereby alerting passengers to safety and prompting operators to perform maintenance in a timely manner to ensure proper operation of the equipment.

[0021] In some technical solutions, optionally, the alarm device includes an audible and visual alarm and / or a buzzer to achieve rapid alarm.

[0022] According to a second aspect of the present application, a personnel transport device is provided, comprising the braking system of the escalator and the moving walkway provided by any of the above technical solutions. Thus, the personnel transport device has all the beneficial effects of any of the above technical solutions, which will not be described in detail here.

[0023] In some technical solutions, optionally, the personnel transport equipment is an escalator or a moving sidewalk.

DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0033] The following combination Figures 1 to 3 , the braking system of the escalator and moving walkway and the personnel conveying equipment provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0034] Reference Figure 1 and Figure 2 In an embodiment of the present application, a braking system for an escalator and a moving walkway is provided. The braking system includes a brake disc 11, a brake belt 12 and a temperature monitoring device 13.

[0035] Specifically, a brake disc 11 is mounted on a drive shaft 21 of an escalator or moving sidewalk. A brake belt 12 extends around the brake disc 11, effectively being sleeved on it. The ends of the brake belt 12 are secured to fixtures 22 of the escalator or moving sidewalk. A temperature monitoring device 13 monitors the temperature of the brake belt 12 and is connected to the escalator or moving sidewalk's safety control circuit 23. This device can control the start and stop of the escalator or moving sidewalk based on the temperature of the brake belt 12.

[0036] In the above embodiment, a temperature monitoring device 13 is installed in the escalator or moving walkway to monitor the activation state of the brake system, and the temperature monitoring device 13 is connected to the safety control circuit 23 of the escalator or moving walkway. When the temperature of the brake belt 12 exceeds a first temperature threshold, the temperature monitoring device 13 can control the escalator or moving walkway to stop operation through the safety control circuit 23; when the temperature of the brake belt 12 is less than a second temperature threshold, the temperature monitoring device 13 can control the escalator or moving walkway to resume operation through the safety control circuit 23. In this way, the braking system can be kept within a reasonable temperature range during normal operation. When an abnormal situation occurs, the temperature monitoring device 13 can promptly control the escalator or moving walkway to stop operation, avoiding the occurrence of serious accidents such as subsequent smoke emission due to excessive temperature, thereby reducing the impact of equipment failure on operational services and improving the quality of operation and maintenance.

[0037] It is understood that the first temperature threshold is greater than or equal to the second temperature threshold, so that the escalator or moving walkway can be guaranteed to operate in a healthy and stable manner. In actual applications, the first temperature threshold can be appropriately greater than the second temperature threshold to leave a safety margin, thereby avoiding frequent starts and stops.

[0038] Reference Figure 1 、 Figure 2 and Figure 3 In some embodiments, the temperature monitoring device 13 includes a temperature probe 131 and a temperature controller 132. Specifically, the temperature probe 131 is used to monitor the temperature of the brake band 12; the temperature controller 132 is connected to the temperature probe 131 and the safety control circuit 23, and is used to receive the temperature data monitored by the temperature probe 131 and compare it with a preset temperature threshold. When the temperature exceeds a first temperature threshold, the temperature controller 132 sends a stop signal to the safety control circuit 23; conversely, when the temperature is less than a second temperature threshold, the temperature controller 132 sends a resume signal to the safety control circuit 23.

[0039] In the above embodiment, the thermostat 132 also includes a display panel 1321. The display panel 1321 is used to display the temperature data monitored by the temperature sensor 131 in real time. This allows maintenance personnel to visually observe the temperature of the brake belt 12 without relying on other tools or equipment for measurement, facilitating fault diagnosis and maintenance work. It also helps maintenance personnel analyze the system's operating status, predict potential problems, and develop appropriate maintenance plans.

[0040] Refer to the attached Figure 3 In some embodiments, the thermostat 132 also features a temperature adjustment button 1322 that works in conjunction with the display panel 1321, allowing operators to adjust the temperature threshold. PV (Practical Value) represents the actual measured value, and SV (Set Value) represents the set value. The SET button is used to set the temperature value. This allows the system to address the impact of varying operating environments, load conditions, or seasonal changes on brake system temperature, thereby improving the reliability and applicability of the brake system.

[0041] In practical applications, the thermostat 132 is connected to a 24V DC voltage and is safely grounded to prevent equipment damage and personal injury.

[0042] In some embodiments, the temperature sensor 131 is disposed on the surface of the brake band 12. This allows for rapid detection of temperature changes in the brake band 12, ensuring real-time and accurate temperature data and avoiding errors that may be introduced by indirect measurement methods. When the brake band 12 exceeds a temperature threshold, the thermostat 132 can react promptly, preventing potential safety risks.

[0043] In practical applications, the temperature sensing probe 131 is adhered to the surface of the brake band 12 , thereby facilitating disassembly and maintenance.

[0044] In the above embodiment, the temperature probe 131 is fixed to the surface of the brake band 12 via thermally conductive silicone 133. Thermally conductive silicone 133 has excellent adhesion, thermal conductivity, and heat resistance. It not only firmly fixes the temperature probe 131 to the surface of the brake band 12, but also forms a good heat conduction path between the two, thereby helping to improve measurement accuracy and real-time performance. Furthermore, the thermally conductive silicone 133 also has a certain degree of elasticity, thus providing a certain degree of protection for the temperature probe 131.

[0045] In some embodiments, the braking system of the escalator and moving walkway further includes an alarm device 14. The alarm device 14 is connected to the temperature monitoring device 13. Thus, when the temperature monitoring device 13 detects that the temperature of the brake belt 12 approaches or exceeds a first temperature threshold, the alarm device 14 can promptly sound an alarm, thereby alerting passengers to safety and prompting maintenance personnel to perform timely maintenance to ensure normal operation of the equipment.

[0046] In the above embodiment, the alarm device 14 includes an audible and visual alarm 141 and a buzzer 142 to achieve rapid alarm.

[0047] In some embodiments, the present application further provides a personnel transport device, which includes the braking system of the escalator and moving walkway provided in any of the above embodiments. Therefore, the personnel transport device has all the beneficial effects of any of the above embodiments, which will not be repeated here.
