When the traveling trolley frame is driven by the driving walking mechanism to walk along the track, the four driven rollers are respectively in contact with the lower surface and the upper surface of the lower wing plate of the track and generate rolling friction force to make the trolley walk along the track.

[0062] Further, in order to prevent the traveling trolley from shaking on the track when walking along the track, the floating simulation traveling trolley further comprises a plurality of groups of guide wheels 412 installed on the inner walls of the inner side plate and the outer side plate and corresponding to each other to roll along the two side walls of the web plate of the track.

[0070] The two winding drum assemblies of each group of winding drum assemblies are symmetrically located on the left and right sides of the corresponding speed reducer assembly (see Figure 13 ), and the spacing between the two winding drum assemblies of the first group of winding drum assemblies and the spacing between the two winding drum assemblies of the second group of winding drum assemblies are different, as shown in the figure Figure 13 ​As shown, the structure that the spacing between the two reel assemblies of the first group 514 is greater than the spacing between the two reel assemblies of the second group 521 can be adopted, so that the spacing between the two reel assemblies in front is smaller than the spacing between the two reel assemblies in back along the walking direction of the trolley, the shoulder of the experimenter can be hung by the pair of reel assemblies with smaller spacing, the back or waist of the experimenter can be hung by the pair of reel assemblies with larger spacing, the human body shape is adapted, and the experimenter is hung more comfortably and safely by the four reel assemblies simultaneously. In application, the four reel assemblies can be simultaneously or individually actuated according to actual needs, so that the experimenter can realize pitching and other actions.

[0071] The four reel assemblies of the utility model all adopt the same structure, comprising: a reel whose rotating shaft is connected with the output shaft of the double-output shaft speed reducer through a shaft coupling; a steel wire rope whose one end is wound on the reel and the other end is used for hanging the experimenter; and a rope pressing wheel structure 510 arranged on one side of the reel, which is used for pressing the rope pressing wheel of the steel wire rope wound on the reel to prevent the rope from being disordered. The rope pressing wheel structure can adopt the prior art structure, which will not be described in detail here.

[0072] In application, the two sets of floating simulation components are simultaneously moved by the floating simulation trolley to simulate the space floating action, and the four reel assemblies in one set or two sets of floating simulation components are individually or simultaneously actuated, so that the two experimenters hung by the two sets of floating simulation components can individually or simultaneously realize pitching or lifting motion, for example: the steel wire rope is simultaneously released by a pair of second reel assemblies in the two sets of floating simulation components, and the steel wire rope is simultaneously wound by a pair of first reel assemblies, so that the two experimenters hung by the two sets of floating simulation components can experience synchronous diving motion; the steel wire rope is simultaneously wound by a pair of second reel assemblies and a pair of first reel assemblies in the two sets of floating simulation components, so that the two experimenters hung by the two sets of floating simulation components can experience synchronous ascending motion; the steel wire rope is released by the first reel assemblies in the first set of floating simulation components, and the steel wire rope is wound by the second reel assemblies, while the steel wire rope is simultaneously released by the two reel assemblies in the other set of floating simulation components, so that the experimenter hung by the first set of floating simulation components can experience backward tilting motion, and the experimenter hung by the second set of floating simulation components can experience descending motion. The specific actions of the two sets of floating simulation components can be performed according to the needs of space station simulation motion, so that the two experimenters hung by the two-person lifting mechanism can individually or synchronously realize various floating simulation actions of the space station, and the interest and interactivity are increased.

[0073] In conclusion, the double-person lifting mechanism for realizing the space station R-VR-R experience can make two experience persons simultaneously get on the real simulation space station, and cooperate with other mechanisms, such as wearing VR headsets in the annular space station experience area of the simulation space station, so that the two experience persons can be immersed in the virtual reality space station environment, and can interact, and the experience reality is increased.

[0074] Although the utility model has been described in detail above, the utility model is not limited thereto, and those skilled in the art can make various modifications according to the principle of the utility model. Therefore, any modification made according to the principle of the utility model should be understood as falling within the protection scope of the utility model.
