Before the spring melt thaw and winter, due to the large temperature changes, switch rails before crawling single turnout drawings, can easily cause turnout Lock device failure. Turnout motor fixed on the outer locking steel pillow, pillow steel rail is connected to the basic single turnout, while the locking lever and switch rail is connected. Under normal circumstances, the motor operation of the locking lever on the same straight line and the outer tie rod locking device. When Turnouts device converts the traction motor lock rod lever action by action type single turnout turnout, due to the influence of temperature, when the temperature rises tip rail generally crawl, when the temperature decreased sharp track general crawling backwards in Under a fixed steel pillow case, because the tip of the rod and rail locking bar crawling action is not a straight line, resulting in an angle, if not fixed steel pillow moves in the opposite direction, the greater the angle between two shots. When Turnouts equipment operation, converting the force being decomposed, making it easy to convert blocked. Heart can cause heart rail track crawling drawing board and card outer locking occurs between the rod mill, under normal circumstances, the locking lever to pull the plate above the ordinary single turnout, Turnouts equipment when converting the drawing board for Xpress rail arc motion external locking lever in the operation of the lever action, in a straight line. After crawling track mind, if the outer locking lever pull completely off or partially off the board, it will make both happen mill card, switch not properly pulled, so large variations in temperature regulation must be combined to eliminate crawling on electrical equipment affecting traffic. Most take the square steel pillow ways to make smooth lever up to standard single turnout chart, single turnout, machinery supplied by Lin Xin Yang Xin Yang Machinery Industrial Co., Ltd. Taizhou.
