Problems solved by technology

During the spring thaw and before winter, due to the large temperature change, the point rail of the turnout will crawl back and forth, which will easily cause the failure of the outer locking equipment of the turnout.
[0003] Existing railway turnout display rod joint devices have poor adaptability to the crawling of the switch rail. When the switch rail crawls along the track direction of the rail, the position of the display rod will change, which will not only cause abnormal gap information or jamming, and even cause the train to The impact of the wheel to the rail causes the breakage of the indicator rod and the joint device

Abstract

The invention relates to the field of railway equipment, and discloses a railway turnout indication rod device. The railway turnout indication rod device comprises a connecting piece, a joint piece, an indication rod and a limiting structure, wherein the connecting piece is configured to be connected with a point rail on one side of a stock rail; one end of the joint piece is rotationally connected with the connecting piece; the indication rod is connected to the other end of the joint piece; the limiting structure is connected with the stock rail and used for limiting the indication rod in the length direction of the stock rail. The method can solve the problem that the gap information in the point switch is abnormal and even jammed due to point rail creeping, is beneficial to reducing the field failure rate, prolongs the adjustment period of an indication gap, greatly reduces the field maintenance workload, and plays a positive role in driving efficiency and driving safety at the same time.

Description

technical field [0001] The invention relates to the field of railway equipment, in particular to a railway turnout indicator rod device. Background technique [0002] The railway turnout indicator rod is the connecting rod between the switch machine and the switch rail (core rail), which is used to transmit force and displacement to correctly feedback the switch position. Before spring thawing and winter, due to the large temperature change, the point rail of the turnout will crawl back and forth, which will easily cause the failure of the outer locking equipment of the turnout. [0003] Existing railway turnout display rod joint devices have poor adaptability to the crawling of the switch rail. When the switch rail crawls along the track direction of the rail, the position of the display rod will change, which will not only cause abnormal gap information or jamming, and even cause the train to The impact of the wheel to the rail causes the breakage of the indicating rod an...
