Description

Tank container walking structure

Technical Field

The invention relates to a tank container walking board structure.

Background

The tank container is a transportation carrier capable of loading goods, is a main transportation mode of modern chemical logistics, has the advantages of safety, environmental protection, good economy, high efficiency and the like, and can meet the requirements of multimodal transportation. The walking platform is a working platform positioned at the top of the tank container, and is convenient for a user to carry out top loading and unloading operation. The prior tank container walking platform usually takes a support piece welded on the inner side of an upper side beam of a frame as a main bearing structure, and then a footpath and the support piece are fastened through bolts; or welding a supporting structure on the tank body and then connecting the footpath and the supporting structure through bolts. FIG. 1 is a sectional view of a common deck structure of a tank container with an upper side beam, wherein the deck structure shown in FIG. 1 comprises an upper side beam 1-1, a deck support 1-2 at the inner end of the upper side beam 1-1 and a footpath 1-3; the walking board supports 1-2 are welded at the inner ends of the upper side beams 1-1, the footpath 1-3 is positioned on the upper surfaces of the walking board supports 1-2, and the footpath 1-3 is connected with the walking board supports 1-2 through fasteners, bolts, washers and nuts; for the above arrangement of the tank container deck structure, the tank is required to have an upper side beam, so that the tank structure is limited, and for the tank requiring the enlargement of the load and the reduction of the self-weight, the presence of the upper side beam also causes the increase of the self-weight of the tank, the increase of the cost, the light weight and the economy of the product, and the market competition. FIG. 2 is a cross-sectional view showing a structure of a conventional deck of a tank container without an upper side sill, in which the tank container shown in FIG. 2 includes a cylinder body 2-1, deck supports 2-2 on the cylinder body 2-1, and a walkway 2-3; the walking plate support 2-2 is welded on the peripheral surface of the cylinder 2-1, the footpath 2-3 is positioned on the upper surface of the walking plate support 2-2, and the footpath 2-3 is connected with the walking plate support 2-2 through a fastener bolt, a washer and a nut; for the arrangement mode of the walking platform structure of the tank container, the walking plate support is directly welded on the peripheral surface of the cylinder body, but when the tank container is provided with the heat insulation material and the heat insulation shell, the walking plate support needs to penetrate through the heat insulation material and the heat insulation shell on the peripheral surface of the cylinder body, and the joint of the opening of the heat insulation shell and the walking plate support is sealed by sealant; the following new problems arise: (1) Stress concentration is generated at the opening of the heat preservation shell, so that the strength of the heat preservation shell is reduced; (2) The heat leakage can occur due to poor metal heat insulation performance of the walking plate support 2, and the heat insulation performance of the tank can be reduced due to the fact that the gap between the walking plate support 2 and the heat insulation shell cannot be effectively and reliably sealed; (3) The metal supporting piece penetrates out of the heat preservation shell, the manufacturing difficulty of the opening is high, and the forming quality is not attractive. In addition, for the tank with the long and thin cylinder, the gap between the cylinder and the top of the tank frame is large, so that the support height of the walking plate is high, the distance between a stress point and a support point is too far, the walking plate is not favorable for walking strength and rigidity, and the safety of products is reduced.
