Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] see figure 1 , the embodiment of the present invention provides an integrated working platform for wheel set maintenance and flaw detection of EMUs, which includes a base 1 and a traction device 2. The base 1 is provided with a track 11 for the EMUs to run on, and the traction device 2 Under the action, the vehicle can be driven along the track 11. For the traction device 2, a tractor is usually used, and a turning bed station 12 and a flaw detection st...

Abstract

The invention relates to motor train unit overhaul and provides a motor train unit wheel set overhaul and flaw detection integrated working platform. The working platform comprises a base provided with a track and traction equipment moving along the track. The base is provided with a lathe position and a flaw detection position in the driving direction of a train. The track penetrates through the lathe position and the flaw detection position. A ballast bed is arranged between the lathe position and the flaw detection position. The length of the ballast bed is not less than that of one carriage. The invention further provides a process, wherein the working platform is adopted for overhaul of a motor train unit wheel set. According to the working platform, the lathe position and the flaw detection position are integrated on the base and arranged in a collinear and staggered mode, so it can be avoided that the lathe position imposes an electromagnetic influence on the flaw detection position; besides, when a 1# bogie of a head carriage corresponds to the flaw detection position, a 1# bogie of a following carriage corresponds to the lathe position, and then synchronous operation at the two positions can be achieved; overhaul time of a whole train can be effectively shortened, and work efficiency is very high.

Description

technical field [0001] The invention relates to the inspection and maintenance of multiple train sets, in particular to an integrated working platform and technology for the maintenance and flaw detection of the train set wheel set. Background technique [0002] With the rapid development of my country's high-speed railway, by 2020, the mileage of high-speed railway will reach 20,000 kilometers, and the number of EMUs will reach 2,000. In order to ensure the safe and efficient operation of high-speed EMUs, regular maintenance is required. However, the state of the running part of the EMU directly affects the driving safety. It is an important measure to ensure the safety of high-speed rail to carry out regular flaw detection inspections on wheels and wheel rim tread repairs. [0003] The existing rim and spoke flaw detection (LU) equipment is installed on the inspection line in the inspection warehouse of the bullet train depot (station), and automatically detects the rim ...
