Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] Such as Figure 1 to Figure 5 As shown, the present invention includes two end chassis 1 and a middle chassis 2, the end section of the web 3 on the box girder at both sides of each end chassis 1 and the box girder at both sides of the middle chassis 2 The 3-end section of the web on the top is set correspondingly, and the 4-end section of the web located on the middle box girder of each end chassis 1 and the 4-end section of the web located on the middle box girder of the middle chassis 2 are also set correspondingly . Each end chassis 1 and the middle chassis 2 are connected by respective webs 3 and 4 respectively, and each end chassis 1 and the middle chassis 2 are connected by bolts to form Integral, form the variable type long truck underframe of the present invention. Wherein, a number of bolt holes are provided at the butt joint ends ...

The invention relates to a variable underframe for an oversize commodity car. The variable underframe comprises two end underframes and a middle underframe, wherein end sections of webs on box-shaped beams located on two sides of each end underframe are corresponding to end sections of webs on box-shaped beams located on two sides of the middle underframe; an end section of a web on a box-shaped beams located in the middle of each end underframe is corresponding to an end section of a web on a box-shaped beam located in the middle of the middle underframe; after each end underframe and the middle underframe are butted by a corresponding web, three connecting devices connect the end underframes and the middle underframe by bolts to form a whole body; and several bolt holes are formed on a butted end of each web. With the variable underframe for the oversize commodity car, variations in length and height can be achieved, type and number of the oversize commodity cars are reduced, the development cycle is shortened, the cost is reduced, the transport efficiency is drastically improved and the running period is shortened. Meanwhile, when two end underframes are directly connected by the connecting devices, a general flatcar is formed for use. The variable underframe can be widely applied in the field of railway commodity transportation.
Description
technical field [0001] The invention relates to a long and large freight car underframe, in particular to a variable type long and large freight car underframe used in the field of railway transportation. Background technique [0002] The large freight car is a special vehicle used in railway transportation. The length of the long freight car is usually 2 to 3 times that of the general freight car. Both the long flat car and the concave bottom flat car belong to the long freight car. The long flat car is mainly used for shipping rails, section steel, bridge steel frames and long mechanical equipment with a low height and long length; the concave bottom flat car is mainly suitable for short, thick and relatively large machine tools, generators, transformers, etc. Transportation requirements for advanced cargo. [0003] The large flat car (or concave bottom flat car) in the currently used large freight car is mainly composed of an underframe, a bogie, an air brake device, a c...
