Description

Car folding box

technical field

The utility model relates to a container, in particular to a folding box for transporting vehicles.

Background technique

With the rapid development of the automobile industry, China's automobile exports experienced a blowout in 2006, with 324,000 complete vehicles exported, with a total value of 3.12 billion US dollars. According to the "Eleventh Five-Year" automobile export plan formulated by the state, the automobile industry should realize the export of 10% of the complete vehicle output, that is, the goal of exporting 1 million vehicles in 2010. At present, the export of automobiles is mainly carried by sea, especially the transportation volume of ro-ro ships is relatively large. However, the mode of ro-ro shipping has many limitations: such as capacity, the need for large quantities, the need for ro-ro docks to dock, and the inability to cover remote areas such as Asia and Africa. Although China's ro-ro ship plan reached 14 in 2010, this contradiction cannot be fundamentally resolved. This provides a market space for containerized transportation.

As a means of freight transportation, containers have developed into an international common means of transportation widely used in multimodal transport in the 1960s. In the field of containers, there is a special bench-type container which is composed of an underframe for carrying goods and end walls which are located at both ends of the underframe and can be vertical to the underframe or folded flat on the underframe. This kind of special platform container is called a folding box because of its structural characteristics that the end wall can be folded and laid flat on the bottom frame.

As shown in Figure 1, a general-purpose folding box generally includes an underframe 100 for placing cargo, an end wall 101 arranged at both ends of the underframe 100, and an end corner of the underframe 100 for connecting the underframe 100 and the end wall. 101 of the hinge device 102 . As shown in Figure 2, the hinge device 102 includes an inner hinge 103, an outer hinge 104 and a hinge locking device (not shown) that are pivotally connected to each other; The bottom end is fixedly connected to the top of the inner hinge 103, and the outer hinge 104 is fixedly connected to the end corner of the bottom frame 100, so that the end wall 101 can be stably maintained in an upright state relative to the bottom frame 100 in the working state, It can also be folded onto the chassis 100 . Due to the small stacking space of folding boxes after folding, the transportation and storage costs of empty boxes are reduced, and the folding boxes also have the characteristics of convenient loading and unloading, so that they can be widely used.

At present, there are more and more transportation companies using folding boxes as vehicles for carrying cars. The overall structure of these folding boxes is compatible with the structural characteristics of cars. As the patent publication number is US6513442 US patent application disclosed a kind of folding box for carrying cars, the overall structure of the box is shown in Figure 3, the box also includes a chassis 100, an end wall 101, for connecting the bottom The hinge device 102 of the frame 100 and the end wall 101, in order to better maintain the stability of the car 140 on the underframe 100, is provided with grooves 106 for receiving the front and rear wheels of the car 140 on the underframe 100. The hinge device 102 used is weak in strength, so a support rod 107 hinged with the end wall 101 and the chassis 100 is provided. In order to facilitate transportation, the general folding box is basically a standard 20 feet (6058mm), 40 feet (12192mm), etc., while the length of a general car is about 5m. Since this folding box can only load a car, the loading The utilization rate of space is low, and the transportation cost is high.

The PCT international patent application with the patent number WO02057113 discloses another folding box for carrying cars. As shown in FIG. , the two ends of the loading frame 108 are detachably hinged with the corner posts 105 . During use, after the hydraulic oil cylinder 109 that both ends are hinged with the underframe 100 and the vehicle loading frame 108 lifts the vehicle loading frame 108 to a predetermined position, the two ends of the vehicle loading frame 108 are hinged with the corner posts 105, and the two ends of the vehicle loading frame 108 are hinged, and the The car can directly be opened on the underframe 100, and the car that will be contained on the loading frame 108 needs to be hoisted with other special hoisting equipment. The manufacturing and maintenance costs of this folding box are relatively high, and the operation is very inconvenient.
