Overhead line system continuous detection device

The invention provides an overhead line system continuous detection device, belongs to the field of overhead line system detection, and solves the problems that an existing measurement mode cannot accurately evaluate the condition of an overhead line system route and is low in measurement speed. A contour detector of the device is arranged on a guide mechanism, is connected with a controller and is used for acquiring contour information of the overhead line system and sending the contour information to the controller; the controller determines the conductor height of the overhead line system,the inclination of the busbar and the distance between the contact line and the monitoring center of the contour detector according to the contour information, and controls the guide mechanism to drive the contour detector to move according to the distance; the guide mechanism is mounted on the traveling mechanism, is connected with the controller and transmits the displacement of the contour detector to the controller; the controller accumulates a plurality of displacements and the initial offset between the monitoring center of the contour detector and the center of the track to obtain a pull-out value; and the running mechanism drives the contour detector and the guide mechanism to move. The device is used for accurately and quickly measuring the condition of the overhead line system line.
