The invention discloses a support bar amplitude variation rotating mechanism of a non-shutdown high-speed rail spanning device, and relates to the field of spanning high-speed rail stringing construction. The support bar amplitude variation rotating mechanism comprises a main beam frame and an auxiliary beam frame which are arranged on the two sides of a high-speed rail and are oppositely arranged; the main beam frame comprises two main stand columns, and masts are connected to the top ends of the two main stand columns through rotating mechanisms respectively; the auxiliary beam frame comprises two auxiliary stand columns; the main stand column and the corresponding auxiliary stand column which are located on the same side support a horizontal support bar, one end of the horizontal support bar is hinged to the rotating mechanism at the top end of the corresponding main stand column, and the other end of the horizontal support bar is connected to the top end of the corresponding auxiliary stand column; and an amplitude variation mechanism is arranged between each main stand column and the horizontal support bar connected to the corresponding main stand column. According to the support bar amplitude variation rotating mechanism, the aims of high-speed rail crossing rapid construction, guide rope feeding and rail passing of a traction rope above the rail are achieved by the spanning device in skylight points.
Description
technical field [0001] The invention relates to the field of stringing construction across high-speed railways, in particular to a luffing and rotating mechanism for non-stop high-speed railway crossing equipment. Background technique [0002] With the continuous acceleration of my country's power grid construction, the length of UHV AC lines is getting longer and longer, and more and more areas cross railways. Especially when crossing the high-speed rail construction, the driving speed is fast, the departure density is high, and the high-speed rail line adopts a fully enclosed and full-overpass design. During the daytime high-speed rail operation, the railway department requires that construction be prohibited, and it can only be operated during the skylight period at night. The operation time is short and the safety is high. The requirements are high and the construction technology is difficult. With the gradual completion of my country's high-speed railway network, it wi...
