[0034] In the related art, the bottom of the rear end of the tank body has a discharge port, and a bottom valve is arranged at the discharge port. In order to provide enough operating space at the discharge port, the bottom beam of the rear end frame of the tank body near the discharge port needs to be broken into two sections, and connected by a bottom plate to form a U-shaped gap, which can prevent The bottom valve interferes with the end lower beam. Due to the existence of the gap, it is necessary to set a rear bottom reinforcement component on the rear frame correspondingly, so as to ensure the strength of the frame. The bottom reinforcement component at the rear end is usually connected between the end frame and the tank body by integral welding, and then painted as a whole.
