The specific embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Please refer to Fig. 1 to Fig. 4, be embodiments of the invention one, the case top that this freight container comprises container body 1 and is positioned at described container body 1 top.Described case top comprises two groups of foldable top cover plates 2, and a side of described foldable top cover plate 2 and described casing 1 articulate by hinge or hinge 10.Every group of foldable top cover plate 2 comprises two top boards that are articulated 20.Two groups of foldable top cover plates 2 are arranged along the Width of described freight container, described two groups of foldable top cover plates 2 away from a pair of top board 20 articulate with described casing 1, and can articulate by pin-jointed structures such as hinge or hinges between two top boards 20 in the foldable top cover plate 2 on the same group.Like this, when foldable top cover plate 2 is opened, namely form a large cargo channel (please refer to Fig. 7) at described casing 1 top.
In order to make things convenient for the unlatching of foldable top cover plate 2, described case top also comprises two groups of folding driving devices 3 that are positioned at two ends, described case top.Every group of folding driving device 3 comprise adjacent with described two groups of foldable top cover plates respectively a pair of top board captive joint two axle drive shafts 31, with two drag-lines 32 of described two axle drive shaft 31 captive joints and two driving pawls 33 that are connected with described drag-line 32 respectively.The axis of described axle drive shaft 31 is lower than the axis of pivot between described two top boards 20.Like this, when driving pawl 33 tightens up drag-line 32, can drive two top boards 20 by axle drive shaft 31 and be pivoted relative to each other, thereby realize the unlatching on case top.When driving pawl 33 loosened drag-line, two top boards 20 namely under action of gravitation, pivoted in the opposite direction, thereby realize the closure on case top.In the present embodiment, described axle drive shaft 31 ends are provided with handle 36, and the end of described drag-line is fixed by described handle 36.
For drag-line 32 is led, thereby make the pulling force that acts on the axle drive shaft 31 by drag-line 32 have better application of force direction, above described driving pawl 33, be provided with drag-line guide rod 34 with the position of described axle drive shaft 31 sustained heights.Described drag-line guide rod 34 is a axle by being welded and fixed.
Please refer to Fig. 6, in the present embodiment, be provided with pin-jointed structure between adjacent two top boards 20 in the same group of foldable top cover plate, described pin-jointed structure comprises two rotating shafts 21 that are fixed therein top board two ends, and two plates 22 of picking up the ears that are fixed on another top board 20 two ends, the described plate 22 of picking up the ears has the through hole that is set in the described rotating shaft 21.By the normal-running fit between described through hole and the rotating shaft, realize being pivoted relative to each other between two top boards 20.
Please refer to Fig. 5, for the unlatching work that makes case top more laborsaving, between described foldable top cover plate 2 and described casing 1, also be provided with pulley gear, in the present embodiment, be separately installed with pulley 35 at described two axle drive shafts 31, described pulley 35 is positioned at described handle 36 inboards, and is set on the described axle drive shaft 31.Be provided with the slide rail 11 that can cooperate with described pulley 35 at described casing 1 correspondence position.Be respectively equipped with position limiting structure 12 at described slide rail 11 near the position at two ends, by the position-limiting action of described position limiting structure, can make described foldable top cover plate 2 reach predetermined folding angle after, be unlikely to further folding.Certainly, in the freight container that folding driving device is not set, pulley gear can be arranged at equally other positions between described foldable top cover plate 2 and the described casing 1, the operator backs down when opening freight container at case, can reach convenient and strength-saving purpose equally.
In the present embodiment, described slide rail 11 is like this designs, top frame in described container body upper end is installed described slide rail 11, described slide rail has the opening towards horizontal direction, like this, described pulley 35 can be connected with roof with the diapire of described opening and be connected, and the sliding trajectory that described opening also has described pulley 35 carries out spacing effect.
For implement closed after to the locking on case top and be convenient to stick on customs seal, (be international land route Shipping Agreement to meet that T.I.R requires, Transport International Router), described case top 1 also comprises the latching device 4 that is positioned at two ends, described case top, described latching device 4 is for being set in the U-shaped lock on described two axle drive shafts 31, and U-shaped is locked and also is provided with the pass seal apparatus.Certainly, for the freight container that folding driving device is not set (freight container of axle drive shaft 31 namely is not set), latching device 4 can be arranged at other positions between described two groups of foldable top cover plates 2, when closed on the case top, the position of described two groups of foldable top cover plates can be locked equally.
Compared with prior art, present embodiment need not can operate on the ground by any exterior mechanical equipment, realizes that the unlatching of top cover is with closed; Because described case top comprises at least one group of foldable top cover plate, after the case top is folding, can form at the top larger cargo channel, and, lamina tecti after folding also can play directional tagging to goods, fast, efficiently loads goods thereby reach, and saves the effect of traffic cost.
Please refer to Fig. 8 and Fig. 9, be embodiments of the invention two, in the present embodiment, the quantity of described foldable top cover plate 2 is two groups, and arrange along the length direction of described freight container, every group of foldable top cover plate comprises four top boards 20, described two groups of foldable top cover plates away from a top board 20 articulate with described casing.Like this, after the case top is folding, can form at the top larger cargo channel equally.Pivot joint mode between this enforcement foldable top cover plate 2 and the casing, the pivot joint mode between the top board 20, and folding driving device and latching device are all roughly the same with embodiment one, therefore not to repeat here.
Please refer to Figure 10 and Figure 11, be embodiments of the invention three, in the present embodiment, the quantity of described foldable top cover plate 2 is four groups, and arrange along the length direction of described freight container, every group of foldable top cover plate comprises two top boards 20, and wherein near in two groups of foldable top cover plates at freight container two ends, two top boards and the described casing contiguous with described freight container two ends articulate; Be arranged in two groups of foldable top cover plates at described freight container middle part, two contiguous top boards and described casing articulate mutually.Like this, after case top is folding, can form at the top two cargo channels larger, that arrange along the length direction of described freight container.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
