[0025] On the one hand, the present invention provides a crane beam track center distance detection device, including a reflection device and a detection device 3, the reflection device includes a first reflector 1 and a second reflector 2 arranged on the central axis of a first track 4, the detection device 3 is configured to move along the center line 7 of the second track, and the detection device 3 includes a laser detector 12, the laser emitted by the laser detector 12 is reflected by the first reflector 1 or the second reflector 2, and the distance from the laser detector 12 to the first reflector 1 and the distance from the laser detector 12 to the second reflector 2 are respectively detected.

[0026] The crane beam track center distance detection device of the present invention comprises a detection device that moves along the centerline of the second track. A laser detector and a reflector are used to measure the distance F from a set point on the second track centerline (i.e., the detection device's location) to a first reflector on the center axis of the first track, and the distance B from the set point to a second reflector. Drawing software is then used to draw a first circle with radius F as the center and a second circle with radius B as the center. The intersection of the first and second circles, facing the second track, is the set point on the second track centerline. Data from multiple set points can be obtained by moving the detection device along the second track centerline, thereby detecting the actual trajectory of the second track centerline. Two reflectors are placed at corresponding positions on the second track centerline according to the above method, so that the detection device moves along the first track centerline to obtain the actual trajectory of the first track centerline. Once the actual positions of the two track centerlines are determined, the track center distance can be determined. The first and second reflectors are generally located at opposite ends of the track.

[0027] Preferably, the detection device 3 includes a displacement sensor for measuring the position of the detection device 3.

When measuring the distance B from the set point on the center line of the second track (i.e., the location of the detection device) to the second reflector, the skeleton 13 is twisted so that the laser detector 12 on the skeleton 13 faces the second reflector and measures the B value.
