Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figs. 1 to 4 As shown in the figure, this utility model embodiment proposes a skid-mounted expander generator multi-shaft transmission device, including a skid-mounted oil station 1. A support platform 6 is movably installed on the upper surface of the skid-mounted oil station 1. A generator 2 is installed on the upper end of the support platform 6. A gearbox 4 is installed on the side of the skid-mounted oil station 1 away from the support platform 6. A coupling 3 is installed on the output end of the generator 2. The coupling 3 is connected to the gearbox 4. The end of the gearbox 4 away from the coupling 3 is connected to the expander. A gearbox shaft head pump 5 is installed on the lower end of the side of the gearbox 4 near the generator 2. An auxiliary pump 7 is installed on one side of the upper surface of the skid-mounted oil station 1. The auxiliary pump 7 and the gearbox shaft head pump 5 are respectively connected to the oil pipes on the skid-mounted oil station 1.

[0021] like Figs. 2 to 4 As shown, in another embodiment of this utility model, the gearbox 4 includes a housing 401, which is bolted to one side of the upper surface of the skid-mounted oil station 1. A low-speed shaft 402 is movably installed through the middle of the housing 401. The end of the low-speed shaft 402 near the generator 2 is connected to the coupling 3. A gearbox shaft head pump 5 is installed at the lower end of the housing 401 near the coupling 3. The output end of the gearbox shaft head pump 5 is movably installed through the interior of the housing 401. A third gear 405 is installed at the output end of the gearbox shaft head pump 5. A second gear 404 is installed at one end of the shaft of the low-speed shaft 402 inside the housing 401. The second gear 404 and the third gear 405 are meshed together. A primary shaft 406 is movably installed through the front and rear ends of the housing 401, respectively. Impellers are installed on the ends of the secondary shaft 407, primary shaft 406, and secondary shaft 407 away from the generator 2 and connected to the expander. A first gear 403 is installed in the middle of the rod inside the housing 401 on the low-speed shaft 402. A fourth gear 410 is installed in the middle of the rod inside the housing 401 on the primary shaft 406 and secondary shaft 407. The first gear 403 and the fourth gear 410 are meshed together.
