The present invention relates to a kind of end wall for foldable container and overturn guiding mechanism, folding container as shown in Figure 1 to Figure 3 is by chassis 1, top cover 2,3, two lower wall 4 of two upper side walls and two end wall (being specially front bulkhead 5 and aft bulkhead 6) compositions。Front bulkhead 5 and aft bulkhead 6 can pass through respective upper end thereof on top cover, time folding, end wall is posted by case varus and is fixed on the case inner face of top cover 2, can also being hinged on chassis by respective lower end, time folding, end wall is to case infolding down to the floor on chassis 1。Front bulkhead 5 is rotatable around front rotating shaft;Aft bulkhead 6 is rotatable around rear rotating shaft。
As shown in Figure 4, the top margin 31 of upper side wall 3 is hinged with the side 21 of top cover 2, and the base 42 of lower wall 4 is hinged with the side 11 on chassis 1, and the base 32 of upper side wall 3 is hinged with the top margin 41 of lower wall 4。After end wall has folded, being folded to direction in case by two sidewalls 3 and 4, top cover 2 falls simultaneously, completes the folding of container, and the vertical process of group is contrary。
As it is shown in figure 5, front bulkhead 5 includes frame, frame includes a front bulkhead entablature 52, two front bulkhead columns 53 of 51, front bulkhead sill。As shown in figure 11, aft bulkhead 6 includes two vertical hinged doors 64 and doorframe, and doorframe includes a doorframe entablature 62, two doorframe columns 63 of 61, doorframe sill, and door 64 is hinged on doorframe column 63 by door hinge 65。
As shown in Fig. 5 to Figure 13, the alien invasion of two front bulkhead columns 53 and the close container side wall of two doorframe columns 63 is provided with the guidance set 7 including at least one rolling member。In first embodiment of the present invention, rolling member is roller 72, additionally, guidance set 7 also includes bearing 71 and roller shaft 73。Bearing 71 can be foundry goods, and it is welded on the lower end of two front bulkhead columns 53 and two doorframe columns 63, and bearing 71 arranges groove 711, is used for holding roller 72 and roller shaft 73, and according to needing, roller 72 and roller shaft 73 can be one。Bearing is additionally provided with screwed hole 712。Roller 72 is optionally rolling bearing。
As it is shown in fig. 7, fixture 75 can be foundry goods, fixture 75 can be a U-shaped part, can be arranged in pairs。It is buckled on roller shaft 73 during installation, links together with bearing 71。It will be appreciated by those skilled in the art that the connected mode of fixture 75 has a variety of。In the present embodiment, each fixture 75 is provided with shoulder hole 751 as shown in Figure 10, bolt (not shown) is screwed into the screwed hole 712 on bearing 71 by shoulder hole 751, it is thus possible to roller shaft 73 is fixedly clamped, when roller 72 and roller shaft 73 are structure as a whole, roller shaft 73 can not be clamped by fixture 75 and bearing 71, and should leave certain interval, so that roller shaft 73 can rotate in the hole that fixture 75 and bearing 71 are formed。It addition, so that contact smooth with sidewall of the rolling member of such as roller 72, the case inner face of container side wall can be provided with the circular arc raceway 74 corresponding with roller 72。
As shown in figure 13, the architectural feature according to container upper side wall 3 and lower wall 4, circular arc raceway 74 can be formed by multiple circular arc flat plate splicings, but smooth in order to contact, it is necessary to after ensureing that container group is vertical, these flat boards face in case is in a perpendicular。
As shown in figure 14, during current, aft bulkhead folded turnover, roller 72 contacts and along rolling path rolling with circular arc raceway 74, and therefore, the center of circle of circular arc raceway 74 should overlap with the axis of rotation of forward and backward end wall or close coincidence。Namely it is arranged on rolling member on front bulkhead 5 and is substantially equal to the circular arc raceway 74 that coordinates with front bulkhead 5 distance to front rotating shaft to the distance of front rotating shaft, and be arranged on rolling member on aft bulkhead 6 and be substantially equal to, to the distance of rear rotating shaft, the circular arc raceway 74 coordinated with aft bulkhead 6 and arrive the distance of rear rotating shaft。
And smooth with what circular arc raceway 74 rolled in order to ensure rolling member, the axial line of roller shaft should intersect vertically with the front bulkhead 5 at its place or the respective rotating shaft of aft bulkhead 6 or close to intersecting vertically。
As shown in Figure 15 and Figure 16, it is an object of the invention to prevent front bulkhead 5 and aft bulkhead 6 in the process of folded turnover with the case inner face scratching of upper side wall 3 and lower wall 4, thus avoiding damage to the sealing strip 9 of front bulkhead 5 and aft bulkhead 6, (this sealing strip is sealing between end wall and sidewall immediately for container group, this sealing strip is fixed on the alien invasion of the close container side wall of two front bulkhead columns 53 and two doorframe columns 63), can also avoid owing to the scratching of front bulkhead 5 or aft bulkhead 6 and upper side wall 3 or lower wall 4 makes end wall folded turnover have some setbacks and damages upper side wall 3 or lower wall 4。Owing to sidewall has upper, middle and lower three row hinge chain, so working as container group immediately, sidewall is likely to can not stand completely directly, and there is the situation of bending in case, so, arises that scratching when front bulkhead 5 and aft bulkhead 6 folded turnover。In the process of end wall folded turnover, the roller 72 of the guide roller assembly of present invention raceway 74 along sidewall rolls, it is possible to by straight for the support of the sidewall of bending in case, it is to avoid the scratching of end wall and sidewall。Owing to roller 72 and raceway 74 are rolling friction, so frictional resistance is less, end wall folded turnover is smooth and easy。For ensureing that only roller 72 contacts with raceway 74, roller 72 should highlight the sealing strip 9 on fixture 75 and end wall。
