The height of the transformer tank 100 with respect to the bottom surface of the vehicle compartment is the height of the bottom end 12 with respect to the bottom surface, and if the height of the transformer tank 100 with respect to the bottom surface is too high, the transformer tank may not pass through a height-limited space such as a tunnel or an overhead bridge, and if the height of the transformer tank 100 with respect to the bottom surface is too low, the transformer tank 100 may collide with the bottom surface of the vehicle compartment during transportation, and the transformer tank 100 may be deformed or damaged. And in this application, through set up different assembly positions on connecting piece 21, if bridging 22 assembles in first assembly position, then when bridging 22 laps on crossbeam 200, the height of the relative bottom surface of bottom 12 reduces, if bridging 22 assembles in second assembly position, then when bridging 22 laps on crossbeam 200, the height increase of the relative bottom surface of bottom 12, so, can adjust transformer tank 100's height to satisfy the transportation requirement.

It will be appreciated that the landing member 22 can be assembled in different assembly positions while the first fastening apertures 221 are aligned with different second fastening apertures 212 and engaged with the fastening members 23 in the same landing assembly 20. Through the arrangement of the first fixing hole 221, the second fixing hole 212 and the fixing member 23, the connecting strap 22 and the connecting member 21 can be conveniently detached and fixed, thereby facilitating the quick adjustment of the height of the transformer oil tank 100.
