The specific embodiment
(as shown in Figure 1) in a preferred embodiment of the invention, provide the pallet 10 that is used for the sea goods freight container, the blocking device that it has the mobile device of roller or roller bearing 20 forms and makes it to be maintained fixed with respect to internal container.
This pallet has the upper surface 11 that is positioned on the chassis 19, and it is porose 12 that this surface is provided with above any roller bearing position, thereby make the pallet of same size to be stacked one by one.
Further preferably, this blocking device comprises a plurality of blocking devices of the diverse location effect that is suitable on the chassis.
First blocking device 30 (Fig. 2) is arranged on the either side of pallet leading edge 14 when this pallet enters freight container.This device 30 is the devices that pivot and install around the shaft element 31 that is arranged on the pallet chassis.
In an embodiment of the present invention, the leading edge 14 of pallet and trailing edge 16 push by Slot shaping and form, and shaft element 31 is arranged between near the pallet leading edge corner the relative groove face.
This Lock Part 30 comprises two parallel facess 32 that pivot and is connected and is separated by element 34 with shaft element 31, and wherein roller bearing 33 can rotate around element 34.This layout makes that when pallet moved into or shifts out freight container, device 30 was parallel to container side wall 15 usually.When the leading edge of pallet during near the interior rear wall of freight container, device 30 can be meshed from the chassis to inner rotary and with container side wall.
Preferably, the device of this pivot installation is a roller assembly.Yet it is contemplated that any suitable installation or any geared assembly may be used to this device.
Second blocking device 40 is associated with the trailing edge 16 of pallet chassis.Blocking device 40 comprises the main element 41 in the trailing edge groove that is welded on pallet rear portion either side, comprises helical element 42 in the described main element, and it can be screwed out such that it terminal 43 is meshed with the sidewall of freight container.
When terminal 43 mesh, preferably, provide lock screw 44 to be connected with main element 41 spirals with lug 45, unclamp to prevent this structure.
The 3rd blocking device 50 is arranged on the groove in-to-in center of pallet chassis trailing edge 16 usually.This blocking device has extensible member 51, and it can be moved into the tight adjacency in one or more back doors with freight container.
