Automatic overhauling system and method for urban rail transit vehicles

Abstract

The invention discloses an automatic overhauling system for urban rail transit vehicles. The system comprises an inspection vehicle device, an automatic boarding ladder device and lifting type trenchplatform devices, wherein the inspection vehicle device comprises a multi-degree-of-freedom mechanical arm and imaging equipment on the mechanical arm; the inspection vehicle device is used for identifying the guide lines of the ground on the two sides of an inspection warehouse track and the bottom of a trench, and inspecting the bottom of the vehicle and the two sides of the vehicle body along the trench and the two sides of a rail; the automatic boarding ladder device is positioned on the side surface of the rail and is used for leading drivers and passengers to normally get on and off thecar when the automatic boarding ladder device rises, and being flush with the ground to avoid passing of the inspection vehicle device when the automatic boarding ladder device descends; the lifting type trench platform devices are respectively arranged at the two ends of the row position of the trench, are flush with the ground when being lifted and flush with the trench bottom when being lowered, and are used for conveying the inspection vehicle device between the trench bottom and the ground. According to the system, manual overhaul can be replaced, missed detection can be effectively prevented, the overhaul time is greatly shortened for being capable of live working, and the operation efficiency of the urban rail transit vehicle is effectively improved.

Description

technical field [0001] The invention belongs to the field of vehicle maintenance of urban rail transit vehicle bases, and in particular relates to an automatic maintenance system for urban rail transit vehicles, which can be applied to the automatic maintenance of urban rail transit vehicles. Background technique [0002] The components of urban rail transit vehicles have a high structural complexity, a large range of maintenance, and a large number of small parts. There are more than 10,000 bolts alone, which may easily cause missed inspections. At present, the daily train inspection of rail transit requires a large number of people and takes a long time. Standard 8-group inspection requires over 10,000 parts to be overhauled. In the existing manual overhaul method, maintenance personnel need to bend over more than 300 times and knock over 5,000 times for a single inspection, which is a high-intensity operation. The maintenance work is mostly in the early morning, and the ...

Problems solved by technology

[0003] Aiming at at least one of the above defects or improvement needs of the prior art, such as but not limited to problems such as complex maintenance procedures, low maintenance efficiency, and hidden safety hazards of existing urban rail transit vehicles, the present invention provides an automatic urban rail transit vehicle The overhaul system uses machine-automatic overhaul system instead of manual overhaul. The overhaul time is greatly shortened, which effectively improves the operation efficiency of urban rail transit vehicles, thereby alleviating social traffic pressure. Due to the automatic overhaul, it can also avoid the missed inspection of manual overhaul and prevent Accidents occur, reducing maintenance and operating costs
