The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.
Referring to fig. 1-6, an air rail train docking device using a fluid cylinder includes a docking rail 100, a rail frame 200 and a fluid cylinder 500, the docking rail 100 is hung on the rail frame 200 through a rope to prevent the rail frame 200 from falling, meanwhile, the docking rail 100 is connected with the rail frame 200 through the fluid cylinder 500 to prevent the docking rail 100 from shaking, and the fluid cylinder 500 has a limiting effect on the docking rail 100.
Specifically, the fluid cylinder 500 includes a cylinder tube 510, a piston 530 and a piston rod 520, the docking rail 100 is connected to the rail frame 200 through the fluid cylinder 500 in two main ways, one is that the docking rail 100 is connected to the cylinder tube 510 of the fluid cylinder 500, the piston rod 520 of the fluid cylinder 500 is connected to the rail frame 100, the other is that the docking rail 100 is connected to the piston rod 520 of the fluid cylinder 500, and the cylinder tube 510 of the fluid cylinder 500 is connected to the rail frame 100. The fluid cylinder can be a hydraulic cylinder or a pneumatic cylinder; fluid cylinders are arranged on two sides of the butt joint rail, the fluid cylinders 500 on the two sides are communicated, all the fluid cylinders 500 can be communicated with each other, or a part of the fluid cylinders 500 can be communicated with each other, the other part of the fluid cylinders 500 are communicated with each other, similarly, two balls are formed, as long as the butt joint rail is deviated, the fluid in the cylinder barrel 510 on one side of the butt joint rail (100) can be circulated to the cylinder barrel 510 on the other side of the butt joint rail, in this way,
that is, both sides of the docking rail 100 are connected to the rail frame 200 through the fluid cylinders 500, so that the shaking of the docking rail 100 in a certain direction or directions can be limited, and meanwhile, a certain offset can be provided when the docking rail 100 is docked; in addition, because of the existence of the fluid cylinder 500, in the solution disclosed in patent 2019101347515, when the docking track 100 is docked, after the concave part and the convex part are aligned, the trolley hanging the docking track 100 stops running and is locked, and at this time, the docking track 100 is lowered, because the fluid cylinder 500 exists and the fluid cylinders 500 at the two sides are communicated, the fluid in the cylinder 510 at one side can circulate to the cylinder 510 at the other side, therefore, the docking track 100 itself has a certain movement amount relative to the trolley, so the docking track 100 moves under the action of gravity and an inclined plane until the precise docking is completed, and the trolley does not need to move, therefore, the whole weight is small, the inertia is small, and simultaneously, due to the buffer action of the fluid cylinder 500, the lowering speed is not fast, and the inertia impact caused by further is reduced; in addition, since the liquid in the cylinder 510 of the fluid cylinder on both sides of the docking track can flow through each other, after the docking is completed and the fluid in the cylinder 510 is stable and does not flow, the docking track does not receive the acting force of the fluid cylinder any more, specifically, if a spring is used to replace the fluid cylinder, the two aforementioned effects are also provided, but if the docking track 100 is not aligned with other tracks in the transverse and longitudinal directions (generally, it is difficult to align) during the movement of the track frame 200, when the docking track 100 moves downwards to complete the docking with other tracks, the docking track 100 moves relative to the track frame 200 until the precise docking is completed, at this time, the acting force applied to the docking track 100 by the spring on both sides of the docking track 100 is different, the resultant force is not zero, so that the docking track 100 tends to move in a certain direction, there is an installation stress between the docking track 100 and the track frame 200, there is a safety concern and the use of fluid cylinders with cylinders 510 in communication does not present such a problem.

Of course, it is not necessary that the proximal rail cavities 550 communicate with each other and the distal rail cavities 560 communicate with each other, for example, the distal rail cavities 560 may be opened to communicate with the atmosphere, and the distal rail cavities 560 may communicate with each other not through a communication pipe, but through the same "atmosphere", and such a scheme is also possible.
Referring to fig. 3 to 6, the rail frame 200 includes a vertically arranged slide rail 210 and a connecting member 220, the connecting member 220 is provided with a roller 230, the roller 230 is matched with the slide rail 210, the connecting member 220 is hinged with a piston rod 520 of a fluid cylinder 500, a cylinder 510 of the fluid cylinder 500 is hinged with the docking rail 100, the telescopic directions of four fluid cylinders 500 are perpendicular to the extension line of the docking rail 100, the telescopic directions of the other four fluid cylinders 500 form an included angle of 45 degrees with the docking rail 100, the number and arrangement of the fluid cylinders 500 are the same as those in fig. 1 and are all parallel to the horizontal plane, so that the docking rail 100 is limited to move in the directions a and B by the fluid cylinders 500, the docking rail 100 can move in the vertical direction by the matching of the roller 230 and the slide rail 210, specifically, since the docking rail 100 is hung on the rail frame 200 by a sling-type device, the lifting of the docking rail 100 can be realized by a, by the cooperation of the roller 230 and the slide rail 210, the lifting frictional resistance can be reduced.
