Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, in the embodiment of the present invention, a semitrailer gooseneck extension device, including extending curb girder assembly 1 and extending device frame 2, extend curb girder assembly 1 total two, two weld between extending curb girder assembly 1 have and extend device frame 2, and extend the welding on curb girder assembly 1 and have mounting panel 3, set up two symmetric distribution's pinhole 5 on the mounting panel 3, and be equipped with two symmetric distribution's alignment structure 6 on the mounting panel 3.

This device passes through 5 articulated assemblies in pinhole of mounting panel 3 with the semitrailer gooseneck and uses, during large-scale load, the extender can prolong gooseneck length, extension semitrailer front overhang, increase towing pin kind and quantity, during empty load, the pneumatic system on the extension device accessible semitrailer, upset to semitrailer body gooseneck upper end, keep the original gooseneck length of semitrailer and parameter setting, and extend 1 upper surface of curb girder assembly and pass through bolt fixedly connected with damping shock absorber 4, damping shock absorber 4 will reduce the vehicle in-process of traveling, the vibrations between extension device and the original gooseneck of semitrailer of upset to semitrailer gooseneck upper end are strikeed.
