The invention discloses a
transmission line breakage detection device. The
transmission line breakage detection device comprises a base, a hollow
guide tube, a conical probe, a spring, a cylindrical probe, a sensor and a controller. The
transmission line breakage detection device is arranged on a walking arm of an inspection
robot, makes contact with a guide line through the probes, senses the external
waviness of the guide line, converts the displacement of the conical probe into
voltage signals through the sensor and conducts analysis according to a
voltage-time image, and whether the guide line breakage occurs or not can be judged by observing whether the frequency of the inspected image is consistent with the amplitude of the inspected image or not. Compared with the prior art, the transmission line breakage detection device has the advantages that negligence of manual routing inspection and negligence of routing inspection of a visible light camera of the inspection
robot are avoided, the defect that the visible light camera has to prevent the
robot from scanning details of the guide line is overcome, and the transmission line breakage detection device is simple, reliable, low in cost and accurate in detection and can not interfere with normal operation of the inspection robot when used as an additional device of the inspection robot.
