Detailed Description

An embodiment of the utility model provides a pair of track offset detection device, track offset detection device includes shock detector 10. The vibration detector 10 is installed on the vehicle body 20 of the automated overhead traveling crane, and is electrically connected to a controller 30 (as shown in fig. 6) of the material handling system, and is configured to obtain vibration amplitude information of the automated overhead traveling crane when the automated overhead traveling crane runs on the track 40 to be measured, and transmit the vibration amplitude information to the controller 30.

Foretell track offset detection device, owing to be provided with shock detector 10 on the automobile body 20 of automation overhead traveling crane, the in-process on the track 40 that awaits measuring is run to automation overhead traveling crane, shock detector 10 can synchronous sensing vibration amplitude information to in time transmit vibration amplitude information for controller 30, thereby just can be favorable to in time accurately detecting out the track offset defect, need not like the artifical manual detection among the conventional art, detection efficiency improves greatly, degree of automation is higher, the maintenance cost is lower greatly.

Referring to fig. 1, in one embodiment, the track offset detection apparatus further includes at least one distance meter 50. The distance meter 50 is mounted on the car body 20 of the automated overhead traveling crane and is electrically connected to the controller 30. The distance measuring instrument 50 is used for acquiring distance information from the distance measuring instrument 50 to the surface of the rail 40 to be measured when the automated overhead traveling crane runs on the rail 40 to be measured, and transmitting the distance information to the controller 30. Thus, the vibration amplitude detected by the vibration detector 10 when the automatic crown block runs on the track without the offset is defined as the standard amplitude, and the vibration amplitude detected by the vibration detector 10 when the automatic crown block runs on the track to be detected 40 is defined as the detection amplitude. When the detected amplitude is greater than the first preset value of the standard amplitude, the first preset value is, for example, 5%, 7%, 10%, 12% or 15% of the standard amplitude, the controller 30 further obtains the distance information detected by the distance meter 50, and judges whether the track offset value exceeds a second preset value according to the distance information, the second preset value is, for example, 0.5mm, 1mm or 2mm, so that the detected amplitude of the vibration detector 10 plays a role in screening the situation that the offset defect may exist, especially for the long track to be detected (for example, the length is 1000m, 2000m, 10000m, and the like), the data volume of the distance meter can be greatly reduced, and the detection efficiency is improved; in addition, when the condition of the fault is determined to exist according to the detection amplitude of the vibration detector 10, the track fault can be accurately detected according to the distance information detected by the distance meter 50, and the phenomenon of detection errors of the vibration detector 10 caused by other factors (such as subway sound waves, wind, rainwater and other environmental factors) can be avoided.

In one embodiment, a material handling system includes the automated crown block of any of the above embodiments, and further includes a controller 30 and a track 40 to be tested.

Step S240, judging whether the distance deviation value is larger than a second set value; when the pitch offset value is not greater than the second set value, the process proceeds to step S260, and when the pitch offset value is greater than the second set value, the process proceeds to step S250;
