电化铁路电车线架线及布缆的专用平车车体

Flat vehicle body used for wiring and cable arranging of electrified railway electric vehicles

Abstract

The utility model discloses a flat vehicle body used for wiring and cable arranging of electrified railway electric vehicles. The flat vehicle body used for wiring and cable arranging of the electrified railway electric vehicles comprises a frame structure and a floor (8), wherein the frame structure is composed of side beams (1), an end beam (2), a middle beam (3), a sleeper beam (4), a large cross beam (5), a small cross beam (6) and longitudinal beams (7), the middle beam is composed of two same-type I beams arranged at intervals left and right, an upper cover plate and a lower cover plate in a welding mode, the two same-type I beams are connected by the upper cover plate and the lower cover plate, the end beam is cold bending unequal angle steel, the side beams are hot rolled steel channels, the left end and the right end of the upper cover plate are extended outwards to be connected with the side beams in a lapping mode, the slipper beam is of a box-type structure with a variable cross section, the large cross beam is an I beam with a variable cross section, the small cross beam is a hot rolled steel channel, and the longitudinal beams of the hot rolled steel channels are arranged between the sleeper beam and the end beam, and between the sleeper beam and the large cross beam. Due to the fact that the middle beam, the end beam, the side beams, the sleeper beam and the like are optimized in structure, on the one hand, strength and rigidity of the vehicle body are greatly enhanced, on the other hand, manufacturing processes are reduced, and working hours are shortened.
本实用新型公开了一种电化铁路电车线架线及布缆的专用平车车体,包括由侧梁(1)、端梁(2)、中梁(3)、枕梁(4)、大横梁(5)、小横梁(6)和纵向梁(7)构成的框架结构,以及地板(8),中梁由两个左右间隔设置的同型号的工字钢、以及将这两个同型号工字钢相连的上、下盖板焊接而成,端梁为冷弯不等边角钢,侧梁为热轧槽钢,且上盖板的左右两端向外延伸后与侧梁搭接,枕梁为变截面箱型结构,大横梁为变截面工字型钢、小横梁为热轧槽钢,在枕梁与端梁之间、枕梁与大横梁之间安装有热轧槽钢的纵向梁。通过优化中梁、端梁、侧梁、枕梁等的结构,一方面大大提高了车体强度及刚度,另一方面减少了制造工序,缩短了工时。
