Description

Technical Field

[0001] This utility model relates to the field of escalator and elevator technology, specifically to an escalator and elevator data access device. Background Technology

[0002] Escalators and elevators are fixed electrically driven devices with circulating steps used to transport passengers upwards or downwards at an angle. They fall under the broad category of elevators and cannot be used as fixed stairs when not in operation.

[0003] With the rapid development of urban rail transit, commercial complexes and other places, escalators and elevators have become the core equipment for vertical transportation of people. Their operational stability and safety are directly related to the safety of public travel. In order to detect potential risks such as wear and tear of mechanical parts and electrical faults of escalators and elevators in a timely manner, it is necessary to collect equipment operation data through data access devices to realize fault early warning and diagnosis.

[0004] In existing escalator data access devices, the connection plugs and mounting plates are mostly fixed by direct bolt tightening. However, the number of connection plugs is too large, the installation space is crowded, and the bolts are prone to interference with surrounding components during installation. The operation is cumbersome and inefficient. Moreover, escalator fault sensors cannot comprehensively capture multi-dimensional operating signals such as vibration, temperature, and noise of key escalator components. Furthermore, the data processing and communication methods are limited, which can easily lead to missed fault detection or delayed early warning. These devices cannot meet the actual needs of high-reliability operation and maintenance of escalators. Therefore, an escalator data access device is proposed to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1 - Figure 6 An escalator data access device in this embodiment includes a housing 1, a signal acquisition device, and an analysis and diagnostic card. A protective door 2 is movably installed on the front side of the housing 1, and the back of the protective door 2 contacts the front side of the housing 1. An installation plate 3 is fixedly installed inside the housing 1. An access plug 4 is provided on the front side of the installation plate 3. Installation blocks 5 are fixedly installed on both sides of the access plug 4. An insertion block 6 is fixedly installed on the front side of the installation plate 3. An insertion sleeve 7 is fixedly installed on the surface of the installation block 5. A limit component 8 is provided inside the insertion sleeve 7.

[0027] The limiting assembly 8 includes a limiting rod 81, a limiting block 82 fixedly installed on the back of the limiting rod 81, and two sets of limiting balls 83 inside the sleeve 7, which are rolled inside the mounting block 5.

[0028] In use, align the connector 4 with the mounting plate 3, align the plug 6 on the mounting plate 3 with the sleeves 7 on the mounting blocks 5 on both sides of the connector 4, and push the connector 4 towards the mounting plate 3. As the plug 6 is inserted into the sleeve 7, it will squeeze the two sets of limiting balls 83. The limiting balls 83 roll along the inside of the mounting block 5 and move to the sides until the plug 6 is fully inserted into the sleeve 7. At this time, the limiting block 82, with the cooperation of the limiting rod 81, limits the limiting balls 83 to prevent them from rolling excessively. Finally, the limiting balls 83 are locked onto the side wall of the plug 6, realizing the quick positioning of the connector 4 and the mounting plate 3 and preventing the connector 4 from shaking.

[0029] The limiting component 8 also includes a connecting block 84, the back of the connecting block 84 and the front end of the limiting rod 81 are fixedly installed, the front side of the connecting block 84 extends through to the front side of the insert 7 and slides with the insert 7, and the mounting block 5 has a roller groove 85 inside, and the limiting ball 83 and the roller groove 85 are rolled together.

[0030] A round block 86 is fixedly installed inside the sleeve 7. A spring 87 is sleeved on the surface of the limiting rod 81. The back of the spring 87 is fixedly installed on the front side of the round block 86, and the front end of the spring 87 is fixedly installed on the front side of the connecting block 84.

[0031] In use, align the sockets 7 on both sides of the connector 4 with the plug blocks 6 on the mounting plate 3, and then push the connector 4 to insert the plug blocks 6 into the sockets 7. At this time, the limiting ball 83 rolls along the groove 85 under the pressure of the plug blocks 6 until the plug blocks 6 are completely inserted into the sockets 7. The limiting ball 83 is reset under the elastic force of the spring 87, forming a lateral limit on the plug blocks 6, thereby completing the quick fixation of the connector 4 and preventing the connector 4 from shifting during the installation process.

[0032] Please see Figure 1 - Figure 6 A DC power supply 9 is fixedly installed on the front side of the mounting plate 3. The DC power supply 9 is 12V and 24V.

[0033] The signal acquisition device includes a built-in sensor, a high-speed acquisition card, and an analog signal acquisition module;

[0034] The sensors include a vibration sensor, an infrared temperature sensor, a room temperature sensor, and a noise sensor. The vibration sensor is connected to a high-speed data acquisition card, while the infrared temperature sensor, room temperature sensor, and noise sensor are connected to an analog data acquisition card.

[0035] The analysis and diagnostic card is equipped with an industrial-grade processor, which includes memory and storage units.

[0036] During use, sensors collect vibration, temperature, and noise signals from key mechanical components of escalators and elevators. After processing by a high-speed acquisition card and analog acquisition module, the data is transmitted to an analysis and diagnostic card. The data is then converted, stored, and analyzed at the underlying level. Fault analysis and diagnosis are performed on the real-time data of the escalator / elevator. The system communicates with the escalator / elevator controller and fault diagnosis and early warning platform through various communication methods such as RS485, Ethernet, and 4G to push fault diagnosis results and early warning information.

[0037] The working principle of the above embodiments is as follows:

[0038] When in use, open the protective door 2 on the front side of the housing 1, align the plug 4 with the front side of the mounting plate 3, and make the plug 6 on the mounting plate 3 precisely align with the sleeves 7 on the mounting blocks 5 on both sides of the plug 4. Then push the plug 4 towards the mounting plate 3. During the insertion of the plug 6 into the sleeve 7, it squeezes the two sets of limiting balls 83. The limiting balls 83 roll along the roller groove 85 inside the mounting block 5 to avoid the plug 6 until it is fully inserted into the sleeve 7. At this time, the spring 87 releases its elastic force to push the connecting block 84, which drives the limiting rod 81 and the limiting block 82 to reset. The limiting block 82 restricts the excessive rolling of the limiting ball 83, and the limiting ball 83 clamps the side wall of the plug 6, completing the quick positioning and fixing of the plug 4 and avoiding installation offset or shaking.

[0039] Then connect the 12V DC power supply 9 or 24V DC power supply 9 on the mounting plate 3 to power the signal acquisition device, analysis and diagnostic card and the entire access device, ensuring that each component enters the standby working state.

[0040] Then the signal acquisition device is activated, and the vibration, temperature and noise of the key mechanical components of the escalator are collected in real time through vibration sensors, infrared temperature sensors, room temperature sensors and noise sensors. The vibration sensors transmit the signals to the high-speed acquisition card, and the infrared temperature sensors, room temperature sensors and noise sensors transmit the signals to the analog signal acquisition module. The two types of acquisition components perform preliminary processing on the raw signals.

[0041] The signal processed by the acquisition component is transmitted to the analysis and diagnostic card. The industrial-grade processor on the card performs low-level transformation, storage and deep analysis on the data through memory and storage units to complete the fault identification and diagnosis of the escalator's operating status.

[0042] The analysis and diagnostic card establishes communication connections with the escalator controller and the escalator fault diagnosis and early warning platform through multiple communication methods such as RS485, Ethernet, and 4G, respectively, and pushes fault diagnosis results and early warning information in real time, so as to realize real-time monitoring and abnormal early warning of the escalator's operating status.

[0043] When it is necessary to disassemble or maintain the access device, the connecting block 84 can be pulled forward. The connecting block 84 drives the limiting rod 81 and the limiting block 82 to move forward, the spring 87 is compressed, and the limiting ball 83 releases the lateral limiting of the plug 6, so the access plug 4 can be easily pulled out to complete the disassembly operation.

[0044] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
