The invention relates to a travel limit switch device and a working method thereof. The travel limit switch device not only can ensure that a turnout strand rail is transferred in or spanned by 100%,but also has double-point transmission, mutual backup redundancy and long service life. Two guide plates are relatively fixed on a bracket in a non-contact manner to form a convex rail; and sliding grooves are formed in the two sides of the sliding base, the sliding grooves in the two sides of the sliding base are in concave-convex sliding fit with a convex rail formed by the guide plate, a springlimiting guide rod connecting threaded hole is formed in the sliding base, the guide rod is sleeved with the spring, one end of the guide rod is connected with the threaded hole in the sliding base,one end of the spring makes contact with a spring limiting boss in the sliding base, the other end of the guide rod penetrates through a sleeve on the support and is locked through a nut, the other end of the spring makes contact with the end face of the sleeve, two microswitches are installed on the two sides of the lower portion of the movable base and are in on-off fit with the movable base, and a rolling wheel is arranged on the upper portion of the sliding base and connected with the sliding base through a pin shaft.
本发明涉及一种既能够确100%地保道岔股轨道转入或跨越,又具有双点传递互为备份冗余且使用寿命长的行程限位开关装置及工作方法,两块导向板相对非接触固定在支架上构成凸轨,滑动座两侧为滑槽且滑动座两侧的滑槽与导向板构成的凸轨形成凹凸滑动配合,滑移座内部开有弹簧限位导杆连接螺纹孔,弹簧套在导杆上且导杆一端与滑移座内的螺纹孔连接、弹簧一端与滑移座内弹簧限位凸台相触,导杆另一端穿过支架上的套筒用螺母锁定、弹簧另一端与套筒的端面相触,微动开关两装在移动座下部两侧且微动开关与移动座形成通或断配合,滑移座上部设置有一个滚轮,通过销轴与滑移座连接。
