Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, and particularly relates to a detachable carriage moving device. Background Art

[0002] In order to facilitate loading and unloading and improve the loading and unloading efficiency, the cargo compartments of current van trucks can basically be separated from the trucks; after the cargo compartment is detached from the vehicle frame, it is not placed in one place and remains stationary, because after being detached from the vehicle frame, it needs to be moved to the loading place or to the storage area after loading, etc.; however, the cargo compartment is generally large in size and heavy after loading, so mobile equipment is often needed to transfer the cargo compartment. The commonly used cargo compartment transfer equipment is roughly as follows: for large van trucks or semi-trailers, using a tractor is the most common transfer method; in some small logistics centers or inside warehouses, forklifts may be used to move smaller van truck carriages or small containers similar to containers; for non-self-propelled small van truck carriages, vehicles with tow hooks can be used for towing; the towing device includes a tow hook, a tow ring, etc., for connecting the towing vehicle and the van truck; in certain special cases, if it is necessary to lift the carriage from the ground to a high place or place it from a high place to the ground, a crane or a hoist can be used for operation; in some fixed logistics centers or factories, a slide rail system may be provided, and the carriage can be slid and transferred through these tracks.

[0003] Relatively speaking, small cargo compartments are easier to transfer. For large and heavy cargo compartments, when using a tractor or a towing device, components connected to the tow hook need to be installed on the cargo compartment, and wheels also need to be installed on the cargo compartment. In this way, it is rather troublesome to modify each cargo compartment, which increases the cost. Moreover, when pulling a heavy cargo compartment for a long time, the cargo compartment is easily damaged locally. The installed wheels have the same specifications and may not necessarily adapt to the road surface environments of different manufacturers, and there may be problems with inconvenient movement.

[0040] A baffle 10 is fixedly arranged between two sub-seat plates in the same group, and the baffle 10 is arranged close to the side of the forklift fork 7 near the main frame 1; the baffle is located on a section where the sub-seat plate extends longitudinally after bending.

[0041] The two seat plates 9 are fixedly connected by a fixing rod 12 to improve the stability and integrity of the seat plate 9.

[0042] Working process: There are two common situations in using this embodiment. One is that after the freight car unloads the cargo compartment, the cargo compartment is transported to the loading place by using it, without affecting the freight car to immediately load other full cargo compartments or without the need for the freight car to drive to the warehouse or other unloading places, preventing congestion, etc.; the second is that after the cargo compartment is loaded with goods, it is transported to other places by using it, such as the place to be loaded or directly transported to the freight car chassis for loading.

[0043] During unloading, the telescopic legs 14 of the cargo compartment are activated to extend, lifting the cargo compartment to make it leave the freight car chassis. After the freight car drives away, the fixing structure is installed on the forklift fork 7 of the forklift 17, and the other end is connected to the bracket. The bracket is moved to directly below the underframe 13 of the cargo compartment by using the forklift 17. The telescopic legs 14 contract, and the girder 15 falls between the two main frames 13. Under the action of the rollers 13 and the upper sliding frame 16, the two girders 15 are accurately fixed between the main frames 13, and the girder 15 falls on the upper surface of the main frame 13. The forklift 17 moves the cargo compartment. After the movement is completed, the telescopic legs 14 extend again, and the forklift 17 moves the bracket to separate it from the underframe 13 of the cargo compartment; the movement process of the cargo compartment after loading is similar; the overall outer dimension of the periphery of the underframe 13 is larger than the outer dimension of the bracket, and the telescopic legs 14 are located outside the underframe 13 in the vertical direction, so the telescopic legs 14 will not affect the bracket to enter below the underframe 13.

[0044] Embodiment 2:

[0045] Differing from Embodiment 1, in this embodiment, when the pulling device is not a forklift but a four-wheeled vehicle, correspondingly, the fixed connection structure includes a horizontally arranged steel plate or bar fixed to the four-wheeled vehicle. Through holes are formed in the steel plate or bar, and the main frame 1 passes through the through holes. On both the left and right sides of the through holes where the same main frame 1 is located, pin holes are horizontally formed. Pins are inserted into the pin holes, so that the main frame 1 is fixed to the steel plate or bar.

[0046] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
