Description
Technical Field
The utility model relates to the field of railway traffic safety, in particular to a switch rail crawling detection tool.
Background
The turnout is one of important equipment for driving, and the running reliability and stability of the turnout are of great importance for the safety and smoothness of driving. The switch rail and the point rail are used as movable parts of the turnout and are used for playing an important role in changing the running direction of the train. The operating condition parameters play an important role in the safe operation of the turnout.
The rail climbing amount of the turnout is divided into the point rail climbing amount and the point rail climbing amount. The point rail climbing amount refers to the longitudinal displacement amount of the switch point rail relative to the point rail. The point rail climbing amount refers to the longitudinal displacement amount of the turnout point rail relative to the wing rail. The creep amount of the switch rail or the point rail is taken as an important operation working condition parameter of the turnout, the creep amount of the switch rail and the creep amount of the point rail are mastered, the turnout is reasonably adjusted through the parameter, the smoothness and the safety of a high-speed train passing through the turnout can be enhanced, the outage event of the turnout without an open signal due to the fact that the creep exceeds the standard is reduced, and the important function is played for the safe operation of the turnout and the ordered operation of lines.
At present, turnout maintainers mainly rely on point rails to mark the turnout point rail crawling reference mark through paint, and manually acquire the point rail crawling amount by checking the distance between the front end of the point rail and the crawling reference mark on the point rail on site.
The following defects exist in the manual acquisition of the crawling amount through the reference mark points: the speed of the train is increased or the operation interval is shortened, so that maintenance personnel can only overhaul the skylight point on the road and cannot climb the skylight point on the road at ordinary times, only the crawling amount of the skylight point can be obtained, and the crawling amount in other time periods cannot be obtained; the precision of the crawling amount obtained by manual measurement through the reference mark point is low under the restriction of the field working environment; the corresponding relation curve of the temperature change and the creep quantity change cannot be obtained, the turnout can be adjusted to an ideal working condition in advance according to weather forecast by grasping the corresponding relation curve, and the occurrence of the event that the train stops running due to turnout faults when the temperature difference changes greatly is avoided.
