The present invention will now be described in details with attached drawings and preferred embodiments which, however, won't be used as a limitation to the present invention.
These and other objects of the invention will be apparent from the following detailed description of the embodiments of the present invention with reference to the accompanying drawings, in which
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
In the present invention, the positioning of the connecting tube 33 can be realized through bolt connection, pin connection or any other effective ways. To ensure a reliable positioning and an effective and easy operation of the guiding and positioning devices (the connecting tube 33 and the positioning and connecting component 34), pin-connected component including the latch 341, the locking pin 342, the chain 343, and the binding ring 344 is usually used as the positioning and connecting component 34 which is used in conjunction with the connecting tube 33.
In the present invention, the form of the support position-limiting assembly won't be limited and can be changed flexibly with the size of cargoes' shapes and structure, e.g., the support position-limiting assembly can be arranged to have one or more groups according to the loading requirements and can be distributed across the base frame. As is shown in
Therefore, in using the support position-limiting assembly 30 for positioning, first the cargo 90 is guided along the guiding surface 35 and gets in contact with the supporting surface 311 of the support position-limiting assembly 30 to carry the cargo, the installation hole 92 in the cargo is then centered with the position-limiting hole 3121, and the latch 341 goes through, and the holed end of the latch 341 is locked and positioned by the locking pin 342 when it goes out of the connecting tube 33.
Thus, through the arrangement of the connecting tube 33, the efficiency of the position limitation is greatly enhanced, and the cargoes can be loaded rapidly and be prevented from damages by using the guiding surface and dunnage, etc., ensuring thus the safety in cargo transportation through the positioning and position-limiting functions of the support position-limiting assembly 30 according to the invention.
INDUSTRIAL APPLICATIONSBy means of the support position-limiting assemblies, it is possible to realize a rapid and reliable positioning, ensuring thus a safe transportation of loaded cargoes.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
