Transport and storage container for liquids

Abstract

The transportation-cum-storage container (1) mainly consists of a plastic inner container (2), an outer grid shell (13) formed of metallic crosspieces and longitudinal pieces (14, 15) crossing each other, for housing therein the inner container (2), and a pallet base (20) having length / width dimensions conforming to the European Steel Community Standards. An upper edge (17) of each longitudinal piece (15) of the grid shell (13) and a double edge (37) of an upper edge forming shape (19) are projection-welded to each other by crosswise butting against each other at six locations. Then the outer edge forming shape (19) of the grid shell (13) has a flat upper rim (44) arranged along it, for bearing corner legs and intermediate legs (23 to 30) of the pallet base (20) of another pallet container (1) stacked thereon.

Description

technical field [0001] The invention relates to a liquid transport barrel and a storage barrel, the barrel has a tray-type chassis, and an interchangeable inner barrel made of plastic, the inner barrel has 4 side walls, a bottom and a top, and the top of the barrel is installed A closable filling connection, an outflow connection for a discharge valve mounted on the lower part of one of the side walls, and a grating casing made of metal vertical and horizontal grating bars to secure the inner barrel, The ends of the vertical grating bars are welded to the top and bottom surrounding edge profiles. Background technique [0002] The similar liquid transport barrels and storage barrels introduced in the patent EP0370307B1 are placed on the same type of barrels. During transportation or stacking, once sideways sliding occurs, such dangers will occur, that is, with corner legs and The upper barrel of the middle foot will slide inwards from the edge pr...

Problems solved by technology

[0002] The similar liquid transport barrels and storage barrels introduced in the patent EP0370307B1 are placed on the same type of barrels. During transportation or stacking, once sideways sliding occurs, such dangers will occur, that is, with corner legs and The upper barrel of the middle foot will slide inwards from the edge profile made of the pipe at the top of the grille casing of the lower barrel, causing the top area of ​​the grille casing of the lower barrel The impact of the weight of the liquid on the upper bucket is expanded downwards, so that the bolts between the diagonally distributed casing stays on the top of the plastic inner bucket and the top edge profiles are loosened, and the plastic inner bucket and the vertical grid bars The welded connection between the profiles at the top edge of the enclosure will be damaged

In addition, during the transportation of overlapping buckets, due to the shock load and collision load, the weld between the vertical grille bar and the top edge profile of the casing will be broken, and the edge profile will be partly or completely detached from the vertical grille bar of the casing. open, thus causing the barrel to be damaged during transport
