Description

Technical Field

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

[0002] An escalator is a fixed electric-driven device used to transport passengers up or down between different floors of a building. An escalator mainly consists of a stairway and handrails. The handrails are installed on both sides of the stairway. The handrails move synchronously with the stairway, and the handrails are used for users to hold on to.

[0003] When the elevator is running, the escalator is mainly driven by the motor, and a drive disc that rotates with the motor shaft is installed on the motor shaft of the motor. The drive disc is connected to the ladder path of the escalator. During the operation of the escalator, in order to improve the safety of the escalator, a monitoring device is generally installed on the escalator. The operation of the escalator is monitored in real time through the monitoring device. When the monitoring device detects that the escalator is running abnormally, the brake device of the escalator brakes the drive disc.

[0004] The existing escalator brake device is generally an electromagnetic mechanical brake, which mainly includes a static brake disc, a dynamic brake disc and a spring. The static brake disc and the dynamic brake disc are located on both sides of the drive disc, and the spring is located on the side of the dynamic brake disc away from the static brake disc. When the brake device is powered on, the dynamic brake disc moves away from the static brake disc under the action of electromagnetic force, so that the drive disc works normally. When the brake device is powered off, the dynamic brake disc moves toward the static brake disc under the elastic force of the spring, and presses against the drive disc to brake the drive disc.

[0005] During the long-term use of the brake device, the dynamic brake disc will wear when braking the driving disc. When the dynamic brake disc wears to a certain extent, it is difficult for the dynamic brake disc to lock the driving disc. However, the staff generally inspects and maintains the brake device regularly, and it is difficult to detect the wear of the dynamic brake disc in time. Utility Model Content

[0029] The following will further elaborate on this application in conjunction with the attached Figures 1 - 4 drawings.

[0030] The embodiment of this application discloses a real-time monitoring trend analysis and warning device for an escalator brake.

[0031] The brake device is generally an electromagnetic mechanical brake, which mainly includes a static brake disc, a dynamic brake disc and a spring. The static brake disc and the dynamic brake disc are respectively located on both sides of the driving disc, and the spring is located on the side of the dynamic brake disc away from the static brake disc. When the brake device is powered on, the dynamic brake disc moves away from the static brake disc under the action of electromagnetic force, so that the driving disc can work normally. When the brake device is powered off, the dynamic brake disc moves towards the static brake disc under the elastic force of the spring and presses tightly on the driving disc to brake the driving disc.

[0032] A real-time monitoring trend analysis and warning device for an escalator brake includes an intelligent acquisition and warning system and a dynamic brake disc dynamic distance monitoring device 1. The dynamic brake disc dynamic distance monitoring device 1 is installed at a position close to the dynamic brake disc. The dynamic brake disc dynamic distance monitoring device 1 is used to monitor the moving stroke of the dynamic brake disc during the braking process of the brake device, and transmit the monitored data to the intelligent acquisition and warning system. Through the intelligent acquisition and warning system, the moving stroke of the dynamic brake disc in the brake device is monitored and analyzed in real time. When the stroke of the dynamic brake disc of the escalator brake device is abnormal, a warning is issued in time, which is convenient for the staff to repair and maintain the brake device in time.

[0033] The dynamic brake disc dynamic distance monitoring device 1 includes a fixed component 11 and a dynamic brake disc dynamic distance monitoring sensor 12.

[0034] The fixing device includes a slide rail 111 and a clamping part 112.

[0035] The slide rail 111 is fixedly installed at a position close to the dynamic brake disc. The clamping part 112 includes a slide block 1121, a fastening net 1122 and a fastener 1123.

[0036] The slider 1121 is installed on the slide rail 111, and the slider 1121 and the slide rail 111 are in sliding fit. A driving unit is also installed on the slide rail 111. The driving unit is used to drive the slider 1121 to move on the slide rail 111. In the embodiment of the present application, the driving unit is a driving cylinder 1111. The driving cylinder 1111 is fixedly installed on the slide rail 111, and the end of the push rod of the driving cylinder 1111 is fixedly connected to the slider 1121.

[0037] The fastening net 1122 includes fastening strips 1125 and fastening ropes 1126. There are several fastening strips 1125. The ends of the several fastening strips 1125 are flush, and the several fastening strips 1125 are distributed along the width direction of the fastening strip 1125. There is a certain gap between the several fastening strips 1125. There are several fastening ropes 1126, and the several fastening ropes 1126 are distributed along the length direction of the fastening strip 1125. Each fastening rope 1126 passes through the fastening strip 1125, and each fastening rope 1126 is fixedly connected to the fastening strip 1125. Each fastening rope 1126 is an elastic rope.

[0038] The fastener 1123 is installed on the side of the slider 1121 close to the fastening net 1122. The fastener 1123 includes two fastening hooks. The two fastening hooks are fixedly installed on the slider 1121 and are arranged oppositely. A plurality of hook tips are fixedly installed on each fastening hook along the length direction of the fastening hook. There is a certain gap for placing the fastening rope 1126 between adjacent hook tips. The hook tips of the two fastening hooks all face the slider 1121. When installing the fastening net 1122 on the slider 1121 through the fastening hooks, the two ends of the fastening net 1122 are made to correspond to the two fastening hooks, and the fastening hooks are inserted between adjacent two fastening strips 1125, and the fastening strips 1125 are pulled by the fastening hooks.

[0039] When installing the dynamic brake disc dynamic distance monitoring sensor 12 on the slider 1121, the dynamic brake disc dynamic distance monitoring sensor 12 is placed on the slider 1121, and the dynamic brake disc dynamic distance monitoring sensor 12 is located between the two fastening hooks. Then, the fastening net 1122 is placed on the dynamic brake disc dynamic distance monitoring sensor 12, so that the length direction of the fastening strip 1125 is consistent with the length direction of the dynamic brake disc dynamic distance monitoring sensor 12. Then, the fastening hooks are inserted between adjacent two fastening strips 1125, and the fastening hooks make the fastening net 1122 press the dynamic brake disc dynamic distance monitoring sensor 12 on the slider 1121 through the fastening strips 1125.

[0040] Since the fastening ropes 1126 are all elastic ropes, it is convenient for the fastening net 1122 to adapt to dynamic brake disc dynamic distance monitoring sensors 12 of different shapes. At the same time, the possibility of damage to the dynamic brake disc dynamic distance monitoring sensor 12 when the dynamic brake disc dynamic distance monitoring sensor 12 is pressed on the slider 1121 is also reduced.

[0041] The dynamic distance monitoring sensor 12 of the moving brake disc includes a mounting base 121, a transmission part 122, and a dynamic distance measuring part 123.

[0042] Both the transmission part 122 and the dynamic distance measuring part 123 are mounted on the mounting base 121, and the dynamic distance measuring part 123 is electrically connected to the intelligent acquisition and warning system through the transmission part 122. The transmission part 122 is a transmission cable.

[0043] The dynamic distance measuring part 123 includes a housing 1231, a measuring member, and a sensor circuit board.

[0044] The housing 1231 is arranged in a cylindrical shape. One end of the housing 1231 is fixedly mounted on the mounting base 121. The measuring member is mounted at the end of the housing 1231 away from the mounting base 121. The sensor circuit board is located inside the housing 1231. The wires on the sensor circuit board are led out through the mounting base 121 and electrically connected to the transmission cable. A positioning groove 1124 is formed on the slider 1121. The positioning groove 1124 is located between two fastening hooks. When placing the housing 1231, place the housing 1231 on it, and position the housing 1231 through the positioning groove 1124 to improve the stability of the placement of the housing 1231.

[0045] The measuring member includes a fixed seat 1232, a measuring rod 1233, and a spring 1234.

[0046] The fixed seat 1232 is fixedly mounted at the end of the housing 1231 away from the mounting base 121. The measuring rod 1233 is slidably engaged with the fixed seat 1232, and the length direction of the measuring rod 1233 is the same as the length direction of the housing 1231. During the movement of the measuring rod 1233, the resistance value on the sensing circuit board changes. The sensor circuit board converts the resistance value into a numerical signal and transmits the measured numerical signal to the intelligent acquisition and warning system through the transmission cable.

[0047] A tightening ring is fixedly mounted at the end of the measuring rod 1233 away from the housing 1231. The spring 1234 is sleeved on the measuring rod 1233. One end of the spring 1234 abuts against the fixed seat 1232, and the other end of the spring 1234 abuts against the tightening ring. The end of the measuring rod 1233 abuts against the moving brake disc under the elastic force of the spring 1234 for a long time. Furthermore, the accuracy of measuring the moving distance of the moving brake disc is improved. In order to reduce the contact stability between the end of the measuring rod 1233 and the moving brake disc, a pulley head is mounted at the end of the measuring rod 1233, and the pulley head makes point contact with the moving brake disc.

[0048] The implementation principle of a real-time monitoring trend analysis and early warning device for an escalator brake in an embodiment of the present application is as follows: When the dynamic distance measurement unit 123 is installed on the slider 1121, the housing 1231 is placed at the positioning groove 1124, and the housing 1231 is positioned through the positioning groove 1124. Then, the fastening net 1122 is placed on the housing 1231, and the fastening hook is installed and inserted between adjacent fastening bars 1125. The fastening hook enables the fastening net 1122 to press the housing 1231 tightly inside the positioning groove 1124 through the fastening bars 1125, so as to improve the convenience and stability of installing the dynamic distance measurement unit 123. Then, the driving cylinder 1111 enables the slider 1121 to drive the dynamic distance measurement unit 123 to move towards the direction close to the moving brake disc, so as to further improve the convenience of installing the dynamic distance measurement unit 123. During the movement of the moving brake disc, the spring 1234 makes the measuring rod 1233 contact with the moving brake disc for a long time. During the movement of the measuring rod 1233, the sensor circuit converts the resistance value into a numerical signal and transmits the numerical signal to the intelligent acquisition and early warning system through the transmission cable. The intelligent acquisition and early warning system analyzes the movement stroke data of the moving brake disc. When the stroke data of the moving brake disc is abnormal, the intelligent acquisition and early warning system analyzes and alarms in time, which is convenient for the staff to repair the brake device in time.

[0049] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
