Abstract
A middle top structure of a carbon steel vehicle comprises a side top plate, a middle top plate, a vehicle top bent beam and a vehicle top side beam. The whole middle top part comprises a frame and a top plate, wherein the frame comprises a cap-shaped vehicle top bent beam, a Z-shaped longitudinal beam and a vehicle top side beam. The two ends of the vehicle top bent beam are directly connected to the vehicle top side beam. The top plate is formed by welding a middle top plate with a side top plate. Through the optimized structure of the utility model, the whole intensity is promoted so the vehicle top steel structure can meet the international universal UIC566 intensity standard.
Description
Technical field
The utility model relates to a kind of roof middle part steel structure of big line passenger train carbon steel car body.
Background technology
The middle part of the big line passenger train roof steel structure of carbon steel car body mainly by two elongated side top boards form (forming), a plurality of carline by side top board and little camber beam, roof side bar, 5 row longerons, middle top board assembly weldings form, the second shape bending part that its carline two ends direct connection side top board is formed.Big line passenger train roof steel structure static strength grade can only satisfy: according to regulation among the TB/T1335-1996 " standard is identified in railway vehicle Intensity Design and test " apply 980KN tensile load, 1180KN clamp load respectively in the car body end time, the maximum stress of generation is less than the permissible stress of material.And the maximum stress that the UIC566-90 standard code produces when applying various compressions, stretching operating mode (as apply 2000KN clamp load, 1500KN tensile load at hitch follower seat place, applying 2000KN clamp load etc. at the side buffer place) respectively in the end is less than the permissible stress of material.As can be seen, the iron target requires standard far below international standard UIC566-90.Thereby the requirement of strength of UIC566-90 standard can not have been satisfied in the middle part of the roof steel structure of big line passenger train.
The utility model content
Technical problem to be solved in the utility model is to optimize the post and beam construction at roof middle part, improves the bulk strength of roof waist longeron, makes the middle part strength grade of roof steel structure meet the UIC566 standard.
For solving the problems of the technologies described above, the utility model provides a kind of carbon steel car body roof central structure, comprise side top board, middle top board, carline, roof side bar, it is characterized in that: whole roof middle part is made up of skeleton and top board, skeleton mainly is made up of hat carline, second shape longeron and roof side bar, the carline two ends directly are connected with the roof side bar, and top board is that middle top board and side top board are formed by tie welding.
The utility model has improved bulk strength by above structure optimization and improvement, makes the roof steel structure can satisfy international UIC566 strength criterion.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, whole roof middle part is made up of skeleton and top board, skeleton mainly is made up of hat carline 1, second shape longeron 2 and roof side bar 3, the carline two ends directly are connected with the roof side bar, top board is that middle top board 5 and side top board 4 are formed by tie welding, and the side top board has been cancelled the second shape bending structure by body inner side.
Claims (1)
1. carbon steel car body roof central structure, comprise side top board, middle top board, carline, roof side bar, it is characterized in that: whole roof middle part is made up of skeleton and top board, skeleton mainly is made up of hat carline, second shape longeron and roof side bar, the carline two ends directly are connected with the roof side bar, and top board is that middle top board and side top board are formed by tie welding.
