The invention belongs to the technical field of rail transit equipment, and particularly relates to a through passage folding shed elbow device which mainly structurally comprises first edge cloth, second edge cloth, third edge cloth, fourth edge cloth, fifth edge cloth, sixth edge cloth and connecting cloth. One end of the first edge cloth is connected with one end of the third edge cloth, and the other end of the third edge cloth is connected with one end of the fourth edge cloth; one end of the second edge cloth is connected with one end of the fifth edge cloth, and the other end of the fifth edge cloth is connected with one end of the sixth edge cloth; the other end of the first side cloth and the other end of the second side cloth are connected with the connecting cloth respectively, the side cloth at the bend is converted into three rings at transverse cloth from single rings at side vertical cloth through lap joint sewing, and when a vehicle passes through a normal curve, the bend is in a folded state, the flatness and attractiveness of the shed cloth frame are not affected; when the vehicle passes through a small curve, a through channel is stretched and deformed, the elbow is in a stretched state, and the folded three-ring shed cloth can ensure that the elbow of the shed cloth have large stretching amount.
本发明属于轨道交通设备技术领域,具体涉及一种贯通道折棚弯头装置,主体结构包括一号边布、二号边布、三号边布、四号边布、五号边布、六号边布和连结布,一号边布的一端与三号边布的一端连接,三号边布的另一端与四号边布的一端连接;二号边布的一端与五号边布的一端连接,五号边布的另一端与六号边布的一端连接;一号边布与二号边布的另一端分别与连结布连接,弯头处的边布通过搭接缝纫由侧立布处的单环转化为横布处的三环,当车辆通过正常曲线时,弯头处于折叠状态,不影响棚布框的平整度和美观性,当车辆通过小曲线时,贯通道拉伸变形,弯头处于拉伸状态,折叠式的三环棚布可保证棚布弯头处有较大的拉伸量。
