Description
Technical field
The utility model belongs to railroad track flatcar equipment manufacturing technology field, and in particular to a kind of rail flat car is with new
Rerail axle support.
Background technology
Railway is the lifeblood of Chinese national economy development, and railway transportation plays very important effect in cargo transport,
It is strong with transport capacity, the characteristics of goods is more are loaded, and in railway transportation, rail flat car can be used directly as important carrier
In transporting steel, timber, automobile, the goods that plant equipment is isometric or weight is larger, other goods can be also transported by container
Thing.Rail flat car also adapts to national defence needs, loads various military hardwares.Flatcar equipped with wild wall also can be used to ship ore deposit
The loose goods such as stone, sandy soil, rock ballast.In recent years, as railway transportation and the fast development of urban track traffic, railroad track are put down
The market demand of car sharply increases, simultaneously because China is vast in territory and the continuous lifting of railway operation speed, various regions weather bar
Part is different, more and more stronger to the Needs of the economy of vehicle, security and effect on environment, it is also desirable to for not
Same demand disclosure satisfy that the railroad track flatcar of different demands.
Rerail axle support is the important feature part of rail flat car, in the use of rail flat car, is particularly and is put down to track
Car is lifted by crane or during rerail operation, rerail axle support need it is larger bears loading force, therefore, for requiring holding for rerail axle support
Power stability is especially important.Traditional rerail axle support is made up of U-shaped backing ring, nut, hanger three parts, and hanger uses welding manner
Be connected with flat car car body, U-shaped knocking over end lifted by crane using helicitic texture and being connected through hanger with nut, in rail flat car or
During rerail, rerail axle support is stressed directly and passes to load at the screw thread that U-shaped backing ring is connected with hanger, and this scheme is present
Problems with：First, vehicle, due to being stressed directly for screw thread, produces stress concentration during long-term use at screwed hole
Phenomenon, " stripped thread " phenomenon is easily produced, potential safety hazard be present；Second, for some climatic environment high humidities and acidity be present
In environment, U-shaped knocking over screw thread is also easy to produce corrosion, and potential safety hazard is equally produced in rerail axle support stress.
Utility model content
