Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the embodiments of the present invention, it should be noted that, if the terms "upper", "lower", "inside", "outside", etc. are used for indicating the orientations or positional relationships based on the orientations or positional relationships shown in the drawings or the orientations or positional relationships that the products of the present invention usually place when using, the present invention is only used for convenience of description and simplification of the description, but does not indicate or imply that the devices or elements indicated must have specific orientations, be constructed in specific orientations, and operate, and thus, the present invention should not be construed as being limited. Furthermore, the appearances of the terms "first," "second," and the like in the description of the present invention are only used for distinguishing between the descriptions and are not intended to indicate or imply relative importance.

In the description of the embodiments of the present invention, it should be further noted that unless otherwise explicitly stated or limited, the terms "disposed" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in the figure, the utility model discloses a packing box 1 of freight train, the girder, a pair of bumper shock absorber and a pair of rear shock absorber, the girder is installed on front axle and rear axle 2 through a pair of bumper shock absorber and a pair of rear shock absorber respectively, it is high stop gear in addition, high stop gear includes a pair of strutting arrangement 3, strutting arrangement 3 includes jacking jar 4 and kicking block 5, kicking block 5 is fixed to be set up on jacking jar 4, jacking jar 4 of a pair of strutting arrangement 3 passes through the detachable installation in rear axle 2 both ends of support, and the kicking block 5 of a pair of strutting arrangement 3 is located the girder below.

The two ends of the lower part of the cargo box 1 are respectively provided with an upper pin shaft seat 31, the top blocks 5 of the pair of supporting devices 3 are respectively provided with a lower pin shaft seat 32, the upper pin shaft seats 31 are connected with the corresponding lower pin shaft seats 32 through connecting blocks 33 and pin shafts, and the central lines of the upper pin shaft seats 31 and the central lines of the corresponding lower pin shaft seats 32 are not on a horizontal translation line. The upper pin shaft seat 31 and the lower pin shaft seat 32 are mainly used for guiding in the lifting process, so that the guiding in the lifting process can be realized, and the hydraulic cylinder caused by overlarge swing amplitude of the rear axle in the lifting process can be prevented from being separated from the rear axle 2. The central lines of the upper pin shaft seat 31 and the lower pin shaft seat 32 are not on a translation horizontal line, so that the situation that the top block cannot contact the girder caused by the same horizontal line is mainly avoided.

And a wear-resistant material layer is arranged on the top block 5.

The jacking cylinder 4 is an electric cylinder or a hydraulic cylinder.

The working mode is as follows: when unloading is needed, the jacking cylinder 4 is started to drive the jacking block 5 to move upwards until the jacking block is jacked on the girder and reaches the maximum limit expansion value of the jacking cylinder (the limit expansion value is a preset value and can reach the maximum value between the container 1 and the rear axle 2), and at the moment, the container 1 is jacked and is always kept at the position, so that unloading can be started.
