Description
(1) technical field
The utility model relates to a kind of large-scale transportation device that is used for goods transport, is specifically related to a kind of frame-type semi-trailer that is used for the carrying freight container.
(2) background technology
In traffic and transport field, a kind of equipment that is called superimposed trailer is arranged, this superimposed trailer is American-European widely used a kind of landlocked long means of delivery apart from the dried food and nuts transportation.
The most frequently used superimposed trailer is the frame-type semi-trailer that is used for the carrying freight container, as shown in Figure 1, this frame-type semi-trailer 1 mainly comprises roof beam structure body 10, be arranged at the wheel 11 of roof beam structure body rear end lower, be arranged on the collapsible supporting leg 12 of roof beam structure body front end bottom, and roof beam structure body 10 front end bottoms also are provided with towing pin (figure does not show); Towing pin is hung in the traction seat of tractor truck during use, and contraction supporting leg 12 gets final product.
In recent years, be to reduce the productive costs of superimposed trailer, its production has the gesture that gradually moves to developing country, so, with regard to there being one superimposed trailer is transported to the problem that makes land used from the grown place.At present, the general-duty practice mainly contains two kinds in sea-freight, and one, use bulk carrier transport, and the cost of this transportation mode is than higher, and the total cost that can cause superimposed trailer to be produced raises; They are two years old, adopt box ship to transport, because the superimposed trailer of same size is longer than freight container, as 20`, the 40` superimposed trailer is all than the 20` of same size, 40` freight container outline is long, this feasible freight container that must design uniqueness for conveying semi-trailer, and can not use general-duty 20`, 40` or 53` freight container, and because box ship is to carry out case position design-calculated by the specification of standard container, so, even if use unique freight container, although can solve the problem of handling, but, cause its conveying efficiency still lower because superimposed trailer can not be placed in the cabin and can not in a row continuous placing.
Hereat, how to improve and frame-type semi-trailer is transported to the conveying efficiency problem that makes land used becomes one of guardian technique problem that industry pays close attention to from the grown place.
