Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] As shown in the figure, a mobile in-storage train bottom detection platform includes a fixed horizontal guide rail 200, which can be set on the train warehousing maintenance line and parallel to the track for train warehousing. A detection device 100 capable of reciprocating movement along the guide rail 200 is mounted on the guide rail 200 . After the train enters the warehouse, the detection device 100 performs image acquisition and flaw detection on the bottom of the train along the guide rail 200 .

[0027] The bottom of the detection device 100 is provided with four groups of traveling devices 110, each group of traveling devices 110 includes at least one traveling wheel 111, more preferably, each group of tra...

Abstract

The invention discloses a mobile in-garage train bottom detection platform which comprises a detection device carried on guide rails, a walking device is arranged at the bottom of the detection device; the walking device comprises walking wheels; the contours of the walking wheels are matched with the contours of the upper surfaces of the guide rails; the detection device is further provided witha rapid detection device and an accurate detection device. The detection platform is used for automatic flaw detection of the train bottom and has the advantages of high positioning precision and highpositioning precision during automatic detection of key parts of the train bottom, prevents the device from moving and shifting by improving the positioning precision, improves the automation degreeof flaw detection of the train bottom and improves the coverage rate of equipment detection.

Description

technical field [0001] The invention relates to the field of automatic detection equipment for train bottoms, in particular to a mobile detection platform for train bottoms in a warehouse. Background technique [0002] Rail vehicles, such as bullet trains, trains, subways, etc., need to be put into storage for maintenance after a period of operation to ensure the safe operation of the vehicles. Generally, due to the complex structure of the vehicle bottom, manual maintenance is required. In order to improve the maintenance efficiency and reduce the labor burden of manpower, automatic detection devices are generally used in the industry for vehicle bottom maintenance to improve the maintenance efficiency. [0003] However, due to the generally long length of rail vehicles, there are many groups of brake pads, axles, wheelsets, etc., which need to be identified and tested one by one. If the detection coverage of important components is low, manual review is required, which red...
