Description
Technical Field
The invention relates to a high-speed railway switch blade monitoring system and a method.
Background
The high-speed railway in China develops rapidly, the traffic mileage exceeds ten thousand kilometers, a large number of turnouts along a railway are considered as a weak link of the railway, and the weak link is directly related to the safety of the operation of the high-speed railway. And most turnout maintenance in China is after-fault maintenance, and in order to guarantee the operation efficiency of the high-speed railway, the smaller the maintenance frequency is, the better the maintenance frequency is, and the shorter the maintenance time is, the better the maintenance time is. In particular, the state of the switch tongue and the movable point rail, and the tightness and the repulsion thereof are influenced by various factors, and the reliability thereof is most concerned.
The high-speed railway in China just started to develop in the last 90 th century. Correspondingly, a plurality of scientific research units and groups research and develop various turnout state monitoring devices and various close-contact inspectors for the turnout of the high-speed railway in China. In China, the gap of the indicating rod is detected by manual detection, experience and visual inspection and the like. In order to realize automatic monitoring, various switch machine gap monitoring devices of ZQJ01 type, DCQK-B type, JJ2002-2 type and the like are developed in China. But the real-time and real-time close contact monitoring is not realized. And with the increasing importance of high-speed railways, whether the turnouts are closely attached is more relevant to the traffic safety. With the increase of the speed, the existing monitoring device can not more accurately check and monitor the state of the turnout. An advanced monitoring device supported by advanced technical conditions is further needed to realize real-time and accurate monitoring. The basic function of the device to be designed and developed is to monitor the point rail contact position of 0-4 mm and the repulsion position of more than 65mm by consulting the relevant specifications, the detailed study of the JMA type contact detector and the investigation of the use sizes of two switches of the Jinghuso train.
Regarding the influence of major diseases of turnout on the close contact of switch rails:
(1) the turnout connection link is loosened. Except that the switch device and the stock rail are fixedly connected, the switch rail root end and the switch anti-creep device, the switch rail or the switch rail iron and the locking rod, the locking rod and the locking hook, the locking hook and the switch rail iron, the indicating connecting rod and the indicating rod are movably connected (ZYJ7 type). The connection gaps which are present at a plurality of points are already at the actual value of the point rail contact when the indication lever gap of the connection terminal is reached. In case the switch rail appears crooked, turns over the back, the level is bad, crawls etc, all can make each connecting rod skew former installation axis, makes the junction bear extra deformation power, aggravates wearing and tearing, increases the clearance to influence close contact, cause not hard up.
(2) The crawling effect. The crawling monitoring mainly depends on manual measurement of the distance change between the rail gap at the first sleeper of the turnout and the tip of the switch rail, and although the measurement is easy and visual, the measurement is subject to periodical inspection, measurement and recording, and is easily influenced by management quality and human factors.
(3) The temperature influence. The length of the slender rod piece of the turnout is necessarily affected by expansion and contraction. Typically the temperature is raised by 50 c and the length of a 2m long rod can be increased by about 1.17 mm. Therefore, the influence of the change of the length of the rod piece in a certain temperature change interval on the specific clearance of the turnout can be calculated.
(4) Tension, influence of card. The 'tension' increases the force output by the switch device, and the excessive sealing force may change the 4mm sealing detection result and even make the turnout unable to start. The tension is caused by poor construction, exists in an internal stress form, has different degrees and is not easy to be found. The 'clamp' occurs at the action edge of the switch rail and the stock rail, and the switch rail cannot be switched in place, cannot be closely attached and cannot be normally locked due to fat edges, switch rail arch, slide plate abrasion, serious slide plate deformation and the like, and cannot be normally unlocked after being locked. .
