Description
Technical field
The present invention relates to a kind of shared flatcar, particularly about a kind of big central sill of railway of railway truck transport field, shared flatcar of little curb girder of being used for.
Background technology
Shared flatcar is to load and transport ordinary goods, can load and transport the flatcar of freight container again.At present, the shared flatcar of multiple model is arranged on the market, these flatcars all adopt central sill, large H-shaped steel structure that the curb girder section is close.The flatcar shortcoming of this structure is that the curb girder section is bigger; In use; The train supervisory personnel can't be deep into underframe inside and carry out inspection and maintenance, can't adapt to the actual conditions that significantly shorten train inspection production time behind the railway speed increase, has influenced flatcar application safety property.
Lay pure wood covering structure on the existing shared flatcar, it is more serious to fail in service, and the vehicle technology state is relatively poor, influences flatcar loading performance, also is to cause short major cause of flatcar repair in shop and shed repair cycle.And, the rope bolt around the existing flatcar and post insert etc. be used for restraint of loads the reinforcement feature loading strength a little less than, can not satisfy the large cargo reinforcement performance needs of raising day by day.
Summary of the invention
To the problems referred to above; The purpose of this invention is to provide and a kind ofly can effectively improve transport capacity; Strengthen cargo loading binding reinforcement ability; Prolong the repair in shop and the shed repair cycle of vehicle, improve train supervisory personnel's operating condition, and can guarantee the big central sill of railway of lorry safe in operation, the shared flatcar of little curb girder.
For realizing above-mentioned purpose; The present invention takes following technical scheme: the big central sill of a kind of railway, the shared flatcar of little curb girder; It is characterized in that: it comprises that a rectangle carries underframe, and said underframe is formed by central sill, curb girder, end carriage, sleeper beam, central transverse beam and big transverse beam assembly welding; The bottom of said underframe is installed on two bogie trucks through basin type cartridge, is separately installed with a brake equipment on said underframe and two bogie trucks, also is respectively arranged with a foundation brake rigging on each said bogie truck; The top of said underframe alternately is equipped with steel wood mixing floor, and said steel wood mixing floor two ends are respectively arranged with two freight container tapered ends, and said steel wood mixing floor middle part is provided with four freight container tapered ends; The two ends of said underframe are separately installed with a cover hitch shock absorber, and are respectively arranged with an end door at said steel wood mixing floor two ends.
Said central sill is positioned at the middle part of said underframe, is the fish belly type and vertically arranges; Said central sill two ends are provided with the mount pad that is used to install said coupler and draft gear; Said central sill is processed by H shaped steel, and its section height is 700mm～800mm.
Said curb girder is arranged on the both sides of said underframe, and said curb girder is pressed into elongated grooved section structure by steel plate, and its section height is 350mm～400mm.
Also be provided with rope bolt and integral type post on the said curb girder and insert, said rope bolt is 14～16.
Said end carriage is arranged on the both ends of said underframe, processes the grooved section structure by steel plate, and said end carriage links into an integrated entity said central sill and curb girder.
The inboard that said sleeper beam is positioned at said underframe top end rail is lateral arrangement, and said sleeper beam adopts the steel plate assembly welding to become box to become section structure; Said central transverse beam is positioned at the transverse center position of said underframe, adopts the steel plate assembly welding to become box to become section structure; Said big transverse beam is positioned at the both sides of said central transverse beam, and said big transverse beam adopts the steel plate assembly welding to become the double-T section structure.
The present invention is owing to take above technical scheme; It has the following advantages: 1, the present invention is owing to adopt the bigger H shaped steel of section as the underframe central sill; And the corresponding section that has increased sleeper beam and central transverse beam; Therefore significantly improve the underframe load-carrying capacity, satisfied the requirement of strength of bigger cargo loading of weight and large-scale heavy duty container loading transportation, also satisfied extraordinary collection cargo requirements on transport such as the bigger tank of weight, Large-scale Railway bridge simultaneously.2, the present invention inserts owing to being provided with heavier-duty rope bolt and inblock cast formula post on curb girder around the underframe and the end carriage, and the bolt quantity of restricting on the full car curb girder increases to 14～16, thereby has improved lade binding reinforcement ability, further improves the goods transport reliability.3, adopt steel wood mixing floor structure on the underframe of the present invention; Steel wood mixing floor alternately is laid on the underframe; Guaranteeing between lade and steel wood mixing floor under the friction force situation; Prolong the useful life on floor, thereby also prolonged repair in shop, the shed repair period of inspection and repair of flatcar, reduced the maintenance cost of vehicle in whole of life.4, the present invention is improving under the underframe integrated carrying ability condition; Suitably reduced the section height of underframe curb girder; Adopt less grooved section structure to replace the H sectional shape that shared in the past flatcar adopts; Thereby greatly facilitate the train supervisory personnel and get into examination and maintenance in the underframe, guaranteed vehicle application safety property.The present invention can be widely used in the railway truck use.
