Crane track detecting device

Abstract

The invention provides a crane track detecting device. A track distance measuring host machine and a height difference measuring host machine need to be used in cooperation; the track distance measuring host machine and the height difference measuring host machine are respectively provided with a first crawling driving device and a second crawling device; the track distance measuring host machineand the height difference measuring host machine can be automatically controlled to move on tracks to realize measurement; the signal acquisition device of the height difference measuring host machinecan collect a laser beam emitted by the laser distance measuring device of the track distance measuring host machine; during the movement of the track distance measuring host machine and the height difference measuring host machine, the signal acquisition device can measure the longitudinal deviation of the laser beam, namely height difference between the two tracks; the laser distance measuringdevice can measure the distance between the two tracks by the retracing process of the laser beam of the laser distance measuring device; and the first leveling device of the track distance measuringhost machine can keep the laser beam emitted by the laser distance measuring device level; the second leveling device of the height difference measuring host machine can keep the signal acquisition device level; and therefore, detection precision can be improved.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a crane track detection device. Background technique [0002] Existing crane track inspection instruments can only measure the track gauge, have a single function, and cannot measure the height difference between the two tracks at the same time. Existing track inspection instruments have no automatic crawling function. When measuring bridge cranes whose track is at a high place, it is necessary to continuously move the measurement point, which increases the risk factor. The lack of automatic leveling function results in large errors in gauge measurement. In response to the above problems, we have invented a crane track detection device using the current stepping motor control technology, laser ranging technology, MEMS accelerometer-based inclination detection and automatic leveling technology, PSD signal processing technology and wireless communication technology.
