Three-gauge turnout

Abstract

The invention discloses a three-gauge mixed gage turnout. The three-gauge mixed gage turnout comprises a trip switch, two movable point rail frogs and four fixed frogs, wherein the trip switch, the two movable point rail frogs and the four fixed frogs are sequentially arranged. The trip switch comprises four stock rails and four switch rails. The four stock rails are the two straight line stock rails and the two curved line stock rails. The four switch rails are the two straight line switch rails and the two curved line switch rails. The four switch rails are connected with a switch device through a pull rod to achieve gang control over opening and closing. The movable point rail frogs are arranged at the position, where two narrow gauges intersect inside a lead curve, of a slide plate for passing through a 1067 narrow gauge locomotive and a 1000 narrow gauge locomotive. Each movable point rail frog comprises a curved line movable point rail and a straight line movable point rail. The four movable point rails of the two movable point rail frogs are connected with two linkage switch devices through two pulling rods to achieve gang control over opening and closing. The four fixed frogs comprise one fixed curved line frog and three fixed straight line frogs. The four fixed frogs are connected into a whole.

Description

technical field [0001] The invention relates to a railway track connecting device, in particular to a three-gauge loop turnout capable of simultaneously passing locomotives of three different gauges of 1435, 1067 and 1000. Background technique [0002] Turnout is a basic connecting device of railway track, which is used to connect different tracks. It has complex structure and high production requirements. Turnouts used to connect tracks with different gauges have more complex structures and higher manufacturing requirements; moreover, turnouts with more gauge specifications have more complex structures and higher manufacturing requirements. [0003] 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 Malaysi...

AI Technical Summary

Problems solved by technology

However, there has not been a double-gauge turnout so far, and there is no three-gauge turnout that can pass 1435, 1067, and 1000 three different gauge locomotives at the same time.

[0005] During the long-term research and experiment, the applicant found that compared with single-gauge and double-gauge simple turnouts, a series of technical problems need to be solved in the manufacture of three-gauge turnouts. , and the fixed straight-line frogs used in ordinary single-gauge turnouts and double-gauge turnouts cannot be used, which is extremely difficult to manufacture; the opening and closing control problems of switch rails and frogs at different positions, etc.
