Three-gauge mantle line rail changer

Abstract

The invention discloses a three-gauge mantle line rail changer. The three-gauge mantle line rail changer comprises two standard rail base rails, a narrow rail 1065, a narrow rail 1000, a point rail A, a point rail B, a point rail C, a point rail D, two connecting rails and two protection rails. The two standard rail base rails penetrate through a rail changer body. The narrow rail 1065, the narrow rail 1000, the point rail A and the point rail B are arranged on the inner sides of the front two standard rail base rails of the rail changer body. The point rail C, the point rail D, the two connecting rails and the two protection rails are arranged on the inner sides of the back two standard rail base rails of the rail changer. The narrow rail 1065 and the narrow rail 1000 each comprise a straight line section and a folded line section. The heel end of the point rail C and the heel end of the point rail D are movably connected to a large shunt heel cushion plate in the middle of the rail changer, and the heel end of the point rail C and the heel end of the point rail D are in contact connection with the tail end of the narrow rail 1065 and the tail end of the narrow rail 1000 respectively. The two connecting rails each comprise a straight line section and a folded line section.

Description

technical field [0001] The invention relates to a railway track connection device, in particular to a three-gauge track changer capable of passing 1435, 1067 and 1000 locomotives with three different gauges at the same time. Background technique [0002] At present, my country's railways are almost a single standard gauge 1435 line, and only the narrow gauge line with a total length of 468 kilometers and a gauge of 1000 is reserved from Kunming, Yunnan to the Sino-Vietnamese border port Hekou. Southeast Asian countries, including Vietnam, Cambodia, Thailand, Myanmar and Malaysia, mainly use 1000-gauge railways, and Japan, Australia and most countries in Africa use 1067-gauge railways. With the rapid development of world trade, it has become a requirement for railways to adopt three-gauge simultaneous running of running wires to adapt to the running of multiple locomotives. [0003] However, when the three-gauge line runs, due to the different gauges and shared rails, the ce...

Problems solved by technology

[0003] However, when the three-gauge line runs, due to the different gauges and shared rails, the centerlines of the two narrow-gauge tracks and the centerlines of the standard-gauge tracks are asymmetrically arranged. Therefore, when two narrow-gauge locomotives need to enter When commissioning or maintaining the workshop in the factory or maintenance yard, a track changing device must be used to make the two narrow-gauge locomotives coincide with the centerline of the track of the workshop commissioning line.

If there is no such track-changing device, it will be inconvenient to maintain, and the simultaneous operation of three-gauge lines cannot be truly realized.
