Description

Technical Field

[0001] The utility model belongs to the technical field of rail vehicles, and more specifically relates to a windshield repair device for a motor vehicle group. Background Art

[0002] After the EMU enters advanced maintenance, in order to ensure the subsequent operation safety of the train, the sealant of the EMU front windshield needs to be cut and updated, and the faulty window glass body needs to be replaced if necessary. At present, there is no suitable maintenance platform in the factory, which makes it impossible to safely carry out the normal maintenance of the EMU front windshield. At present, the process plan for updating the sealant of the front windshield or replacing the windshield window can only call the lifting platform and ferry at the operation site. When the lifting platform is at the lowest position, the ferry is placed across the two ferrys. After it is placed stably, the two ends are fixed on the platform with straps. After the two operators fasten their seat belts, the two lifting platform vehicles are synchronously controlled to rise. After reaching the required height, the horizontal position of the lifting vehicles is synchronously controlled until the required position is reached. This working method requires the lifting platform to be controlled to move multiple times, resulting in a large safety hazard in the working process; and the time of the lifting platform movement process is difficult to grasp, and it is easy to fail to apply glue.
