Because the tank cabin 1 is generally higher, in the outside of tank cabin 1, still can be used for the loading through setting up connection deck 2, the connection deck 2 that sets up simultaneously also can play the supporting role to the vertical leg 12 of tank cabin 1 for tank cabin 1 structural strength is more excellent.

As shown in fig. 1 and 2, the end brackets 15 on both sides are arranged in an arc-like transition on the side wall close to the interior of the tank 1 and extend over the vertical ribs 14 on the side of the longitudinal wall 12. The floating stopping limit devices 4 are symmetrically arranged at two sides of the tank cabin 1, are fixedly arranged below the vertical ribs 14 protruded from the end bracket plates 15, and are fixedly connected with the longitudinal surrounding walls 12 and the vertical ribs 14. The tank body limiting parts 7 are fixedly arranged on two sides of the fuel tank 5 and correspond to the floating stopping limiting device 4.

As shown in fig. 2 and 3, the floating stop device 4 includes a face plate 41, a support plate 42, a web 43, and a bottom plate 44. The panel 41 is integrally connected to and flush with the side wall of the end toggle plate 15 adjacent the interior of the tank 1. The support plate 42 is mounted horizontally and fixedly below the end ribs, with one side connected vertically to the panel 41 and the other side connected to the vertical ribs 14, extending and fixed to the longitudinal walls 12. The base plate 44 is parallel to the support plate 42 and is connected perpendicularly to the panel 41 and extends to the longitudinal walls 12. The web 43 is fixed between the support plate 42 and the bottom plate 44, and is vertically connected to the support plate 42, the bottom plate 44 and the face plate 41. The bottom plate 44 protrudes from the side wall of the end toggle plate 15 on the side close to the inside of the tank body, and extends to the edge of the face plate 41 and the support plate 42, and an auxiliary toggle plate 45 is fixedly mounted on the protruding extension of the bottom plate 44, and the auxiliary toggle plate 45 is vertically connected with the face plate 41 and is connected to the edge of the end toggle plate 15. The outer side wall of the auxiliary toggle plate 45 is in inclined transition and is connected with the edge of the end toggle plate 15 from the outer edge of the bottom plate 44, and the supporting plate 42 preferably extends and protrudes out of the edge of the end toggle plate 15 to be fixedly connected with the upper end of the auxiliary toggle plate 45.
