[0015] Example 1, as Figure 1 and Figure 2 As shown in the figure, the transfer vehicle for installing a fuel cell system proposed in this embodiment includes a chassis, an adjustment component, and a connection component.

[0016] The chassis includes a base 1, two front wheels 6 located at the bottom front end of the base 1, and two rear wheels 7 located at the bottom rear end of the base 1. The rear wheels 7 have brake pads, which the user applies to slow down the vehicle. A longitudinal beam 2 is vertically mounted on top of the base 1.

[0017] like Figure 1As shown, the adjustment assembly includes multiple longitudinal beams 2 mounted on the chassis, crossbeams 3 detachably connected to the longitudinal beams 2, and two overlapping plates 4 detachably connected to the crossbeams 3. The longitudinal beams 2 are vertically distributed, specifically four in a rectangular arrangement, with the four longitudinal beams 2 located above the two front wheels 6 and the two rear wheels 7, respectively. The crossbeams 3 and overlapping plates 4 are horizontally distributed, and the longitudinal beams 2, crossbeams 3, and overlapping plates 4 are perpendicular to each other.

[0018] like Figure 1 As shown, in order to improve the structural strength of the chassis, a reinforcing frame 9 is connected between the base 1 and the two longitudinal beams 2 above the rear end of the base 1, and a connecting beam 10 is also connected between the top ends of the two longitudinal beams 2.

[0019] like Figure 1 As shown, both the base 1 and the connecting beam 10 are equipped with a connecting block 1. A connecting block 2 is detachably connected to the connecting block 1, and a handle 8 is connected between the connecting blocks 1 and 2. The connecting block 1 has an internal thread, and the connecting block 2 has a through hole. A screw is inserted through the through hole and connected to the internal thread, allowing the handle 8 to be clamped using the connecting blocks 1 and 2. Multiple connecting blocks 1 and 2 are provided, allowing the handle 8 to be clamped at multiple points, improving the reliability of the handle 8 installation and facilitating the user's push-pull operation of the entire transfer cart.

[0020] like Figure 1 As shown, the connecting assembly includes four vertically distributed columns 5, with each pair of columns 5 detachably connected to a connecting plate 4. The three-dimensional position of the four columns 5 is adjustable to suit the installation of the target fuel cell system.

[0021] This embodiment allows adjustment of the three-dimensional spatial positions of the four pillars 5 according to the specific fuel cell system specifications, enabling the fuel cell system to be installed on the adjusted pillars 5 for transport. If other fuel cell systems of different specifications need to be installed or transported, the positions of the four pillars 5 can be adjusted accordingly. This transport trolley is highly compatible, flexible in use, and low in cost, eliminating the need to manufacture multiple trolleys to transport different fuel cell systems. The fuel cell system is evenly installed on the four pillars 5, making it less prone to tipping over.

[0022] Example 2, as Figure 1 and Figure 2 As shown, this embodiment proposes a transfer trolley for installing a fuel cell system. Compared to Embodiment 1, in this embodiment, the crossbeam 3 includes a horizontally distributed crossbar portion 32 and two vertical tube portions 31 respectively fixedly connected to both ends of the crossbar portion 32. The vertical tube portions 31 are vertically distributed and have a through-flow design on their inner sides.

[0023] like Figure 2As shown, the longitudinal beam 2 has multiple through holes 201 along the vertical direction. The vertical tube 31 is slidably mounted on the longitudinal beam 2, and the vertical tube 31 has multiple through holes 311 along the vertical direction. The horizontal bar 32 has multiple through holes 321 along its length. The overlapping plate 4 has through holes 401 at both ends. The through holes 401 can be strip-shaped holes to facilitate alignment with the multiple through holes 321. The overlapping plate 4 has multiple through holes 402 between its two ends. The column 5 has a through hole 501 at its bottom. The through hole 501 can be strip-shaped holes to facilitate alignment with the multiple through holes 402. Bolts are threaded through the through holes 201 and 311, the through holes 321 and 401, and the through holes 402 and 501, and the bolts are threaded with nuts.

[0024] When adjusting the position of column 5, column 5 is placed on the overlapping plate 4. The position of column 5 is adjusted along the length of the overlapping plate 4 by aligning the through hole 501 on column 5 with the through hole 402 at different positions on the overlapping plate 4, and by using bolts and nuts. The overlapping plate 4 rests on the crossbar 32. The position of column 5 is adjusted by aligning the through hole 401 on the overlapping plate 4 with the through hole 321 at different positions on the crossbar 32, and by using bolts and nuts. Similarly, the height of the crossbar 3 is adjusted by aligning the through hole 311 on the vertical tube 31 with the through hole 201 at different heights on the longitudinal beam 2, and by using bolts and nuts. This allows for the adjustment of the three-dimensional position of the four columns 5 according to the specific fuel cell system specifications, specifically for the installation and transport of the fuel cell system.

[0025] like Figure 2 As shown, the overlapping plate 4 has a U-shaped cross-section with the U-shaped openings facing upwards. The uprights 5 include a vertical rod portion, a base plate portion fixedly connected to the bottom end of the vertical rod portion, and a mounting plate portion fixedly connected to the top end of the vertical rod portion. The mounting plate portion has mounting holes, and the four uprights 5 have four mounting holes for connection to four external mounting points of the fuel system. The base plate portion is slidably disposed inside the overlapping plate 4 for easy position adjustment. A through hole 501 is located on the base plate portion, ensuring a secure connection between the uprights 5 and the overlapping plate 4.

[0026] In this embodiment, bolts and nuts are used for detachable connection at the through hole, which facilitates the adjustment of the position of the column 5 for installation and transportation of fuel cell systems of different specifications.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
