Example 1
The step system for use between an air rail train and a platform of the present embodiment will be described in detail with reference to fig. 1 to 3, 7 and 8. FIG. 1 is a schematic diagram of a step system for use between an air rail train and a platform in a first embodiment of the present invention; FIG. 2 is a schematic diagram of a step system for use between an air rail train and a platform in a first embodiment of the present invention in a non-operational state; fig. 3 is a schematic configuration view of a step device for a step system between an air rail train and a platform in the first embodiment of the present invention.
As shown in fig. 1 to 3, the step system includes a step device provided on the platform 2 and a docking portion 15 provided on the train body 4. Of course, those skilled in the art can install the step device on the train body 4 and install the docking portion 15 on the platform 2 as necessary. The pedal device comprises a connecting plate 6, a driving mechanism and a transmission mechanism. The drive mechanism is preferably a rotary motor 11. The transmission mechanism comprises a first transmission wheel 9, a second transmission wheel 7, a rotating shaft 5 and a transmission chain/belt 8. Wherein, the first driving wheel 9 and the second driving wheel 7 can be gears or belt pulleys, an output shaft 10 of the rotating motor 11 is connected with the first driving wheel 9, the first driving wheel 9 and the second driving wheel 7 are connected through a conveying chain/belt 8, and the second driving wheel 7 is fixedly connected with the connecting plate 6 through a rotating shaft 5, so that the rotating motor 11 drives the connecting plate 6 to rotate through the first driving wheel 9, the conveying chain/belt 8 and the second driving wheel 7. It can be seen that the transmission mode of the transmission wheel is adopted, so that the rotation precision of the connecting plate 6 is guaranteed, the cost is reduced, and the mass production requirement of public transportation is met. It will be appreciated by those skilled in the art that the rotating electrical machine 11 and the connecting plate 6 may be hydraulically connected, etc., in addition to the connection described above.
With continued reference to fig. 3, in a preferred embodiment, the shaft 5 is supported by a sleeve (not shown), and a lubrication oil passage may be further provided between the shaft 5 and the sleeve, and the lubrication oil passage is connected to a nipple of the oil supply device through an oil delivery pipe. Therefore, lubricating grease can be added into the lubricating oil duct at any time, and the service life of the connecting plate device is prolonged. The rotating shaft 5 is provided with a position sensor 18, such as an angular displacement sensor, which can detect the rotation angle of the connecting plate 6 in real time, so as to accurately obtain the current position of the connecting plate 6. Of course, the person skilled in the art can also arrange the position sensor 18 on the connection plate 6 as desired. An elastic buffer layer 17 is arranged on one side of the connecting plate 6 close to the abutting portion 15, and the elastic buffer layer 17 can be a spring, a rubber block or the like. A pressure sensor 16 is also provided on the side of the connection plate 6 near the abutment 15 for detecting the pressure value during abutment of the connection plate 6 against the abutment 15, for example the pressure sensor may be provided in the elastic buffer layer 17 or at the end of the connection plate 6 etc. The material of the connection plate 6 may be a metal material, a high polymer material, etc., and preferably a material resistant to sunlight, high temperature and rust is used. In addition, the surface of connecting plate 6 still is provided with the skid resistant course to rain and snow weather leads to the surface of connecting plate 6 to slide excessively and the potential safety hazard that brings. The anti-slip layer can be uniformly arranged convex lines or concave lines with a self-drainage function, and can also be a spacer made of anti-slip materials. As can be seen from the above description, the provision of the pressure sensor 16 and the position sensor 18 improves the accuracy of the docking of the pedal device with the docking portion 15, thereby improving the safety performance of the pedal system.
The docking station will now be described with reference to fig. 1, 2, 7 and 8, wherein fig. 7 is a schematic view of a second embodiment of the docking station for a step system between an air rail train and a platform of the present invention; fig. 8 is a schematic view of a third embodiment of a dock for a step system between an air rail train and a platform of the present invention.
As shown in fig. 1, 2, 7 and 8, due to the special application scenario between the aerial rail train and the platform, the connection accuracy and the connection stability of the connection board 6 are far higher than those of other application scenarios, so the purpose of the arrangement of the butt joint part 15 of the present invention is to avoid the phenomena of unstable connection, downward sliding and the like of the connection board 6 caused by the connection accuracy or faults and the like, and further improve the safety coefficient of the pedal device. The docking portion 15 may be a groove (as shown in fig. 7), a rib (as shown in fig. 8) or a recessed step (as shown in fig. 1 and 2) provided in the train body, so that the connection plate 6 is docked with the docking portion 15 in a lap joint or plug-in manner. When provided as a groove, a chamfer may also be provided in the groove to facilitate the rotation of the connection plate 6 in and out. Of course, the installation position of the abutting portion 15 is not fixed, and the abutting portion 15 may be installed in a segment below each train door 3 or may be installed penetrating the train body 4.
The step system for use between an air rail train and a platform of the present invention may also include a separate control unit (not shown), although the control unit may be integrated into the platform control system. The control unit is used for receiving signals for opening/closing the isolation door 1 and the train door 3 from the platform control system and controlling the operation of the driving mechanism according to the signals. The control unit is also used for receiving signals of the pressure sensor 16 and the position sensor 18, judging whether the connecting plate 6 reaches a specified position or not, and making corresponding adjustment when the specified position is not reached. For example, if the pressure data of the pressure sensor 16 does not reach the set threshold, it is proved that the connection board 6 is not completely docked with the docking portion 15, the docking stability of the connection board 6 and the docking portion 15 is insufficient, and a potential safety hazard is easily present, at this time, the control unit continues to control the driving mechanism to act, and the connection board 6 continues to rotate to completely dock with the docking portion 15 under the driving of the transmission mechanism.
For example, in one possible implementation, the control method for the step system between the air rail train and the platform is:
after the air rail train reaches the parking position and before the isolation door 1 and the train door 3 are opened, the control connection plate 6 is butted with the butting part 15; after the closing of the isolation door 1 and the train door 3 and before the air rail train is driven out of the parking position, the control link plate 6 is disengaged from the abutment 15. The control method ensures that the connecting plate 6 is always in a working state (namely, a state of butting against the butting part 15) when the isolation door 1 and the train door 3 are in an open state, fully ensures the safety of passengers, and avoids the occurrence of safety accidents caused by the delayed ejection or the advanced retraction of the connecting plate 6.
The workflow of the step system for use between an air rail train and a platform of the present invention is further described with reference to fig. 1 and 2.
