Description
Technical field
The invention belongs to administrative region of a city railway arts, repair technique more particularly, to a kind of administrative region of a city rolling stock three-level.
Background technique
The purpose of car inspection and repair is to maintain and improves the basic performance of vehicle, ensures the safe and reliable of operation, reduces vehicle
Failure occurs.Administrative region of a city vehicle preferably carries out the maintenance system that " plan and control+status maintenance+equilibrium is repaired " combines in terms of maintenance.Plan
Repair and belong to preventative maintenance with status maintenance, be with plan and control it is leading, repaired according to time and traveling mileage；Status maintenance is root
Maintenance opportunity is determined according to equipment actual techniques situation.It is in the train non-service time that equilibrium, which is repaired, and the off-peak hours are transported using vehicle
Row stoppage in transit window overhauls train, and maintenance content is dispersed in different time sections and different occasions.
Administrative region of a city railway has the design feature of itself compared to subway and high-speed rail, firstly, its speed and range of operation between
Between subway and high-speed rail；Secondly, its operation has flexibility, both it fastly can rise and stop fastly or long transmission line is run；In addition, its passenger capacity
It is bigger compared to high-speed rail.Since the speed volume range of administrative region of a city railway operation is different from subway and high-speed rail, the mill of components
The speed of damage is different, and the time cycle of corresponding components maintenance and replacement is not also identical.
It is referred to the maintenance craft and specification of high-speed rail, EMU and subway etc. in current technology data, but does not relate to
And the specific maintenance detailed process at different levels of administrative region of a city vehicle or details, such as the specific operation process overhauled of the third level or process it is thin
Section.In addition administrative region of a city vehicle is for state's iron or subway, and vehicle major parameter and performance are different, and maintenance craft also has
Corresponding variation.Therefore the maintenance of administrative region of a city rolling stock cannot indiscriminately imitate the maintenance craft process of state's iron and subway completely, when maintenance
It needs to make corresponding change for the characteristics of administrative region of a city vehicle, therefore herein proposes the maintenance craft process that administrative region of a city vehicle three-level is repaired.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the present invention provides a kind of administrative region of a city rolling stock three-level and repairs work
Skill, in conjunction with the operational mode that administrative region of a city rolling stock rises fastly fastly stops itself, the big feature of passenger capacity, in combination with administrative region of a city rolling stock
With the difference on big iron construction, adaptability maintenance is carried out to position easy to wear, increases the overhaul process of section components, deletes
Some unnecessary maintenance crafts in administrative region of a city rolling stock three-level is repaired increase the technique that solution is compiled newly in three-level is repaired, and solution editorial afterword is just
In hitch snap ring is cleaned and overhauled, seal washer in hitch blast connection is replaced；Solution compiles later section vehicle and individually changes steering
Frame changes part, requires to reduce to maintenance craft platform bit quantity, saves resource.
To achieve the goals above, the present invention provides a kind of administrative region of a city rolling stock three-level and repairs technique, and steps are as follows:
