Description
Technical field
The present invention relates to a kind of spraying method of underground insulation rail, belong to steel rail rolling production field.
Background technology
Rail Surface application purpose is to improve the decay resistance and insulation against ground performance of rail, the application work of beam-and-rail rail
Skill uses rail on-line spray scheme.
Beam-and-rail factory paint line process route：
Steel rail universal rolling → roll straightening → surface quality inspection → ultrasonic examination → bidirectional hydraulic is mended strong → online
Spraying → processing scroll saw bore processing → stand close steel → magnetic hang → stacking → magnetic hangs → entrucking delivery.
In the spraying scheme of production line, the process process coating hurt after coating surface drying is serious, mostlys come from
Damage of the roller transport process to the flange of rail.The flange of rail damage of production subway rail can not meet subway rail insulating requirements.
Side obforms spraying can cause flange of rail leg tip position to have a coating abrasion band, and anti-corrosion rail disclosure satisfy that requirement, but absolutely
The integrality of edge track to track bottom point is higher, and the damage to flange of rail coating side can not meet subway rail insulating requirements.
The insulation requirements of subway rail：Track circuit is the fundamental equipments of train operating safety control.It is with rail
For conductor, demarcated with rail insulation, and track circuit is constituted with cable linkup transmit and receiving device, to check for train
Take and transmitted to train the circuit of state of ground information.Whether its reliable operation will directly affect train operation state and effect
Rate, directly affects the safety of transport production.
Major part is caused by track switch and track circuit failure in the phylogenetic driving faults of electricity business, and track circuit event
Major part is caused barrier by damage in insulation again.More complicated due to track insulating damage, it is exhausted that these insulation include steel rail end
The various track insulations such as edge, the insulation of mounting turnout device, tie rod insulation.
Spraying raw material：60 μ m thick coatings of spraying raw material have been carried out 500m Ω class B insulations performances and the salt of thousands of hours
The mist anti-corrosion time.
The content of the invention
The technical problems to be solved by the invention are：A kind of spraying method of underground insulation rail is provided, eliminates or reduces
Rail of subway flange of rail coating hurt, improves product coating coverage rate, meets subway rail requirement.
It is to solve above-mentioned technical problem the technical solution adopted in the present invention：The spraying method of underground insulation rail, steel
Rail includes rail head, the web of the rail and the flange of rail, and spraying method comprises the following steps：
After the completion of steel rail rolling and aligning, first step spraying is carried out to rail by the way of rail is upright or side is fallen,
The first step or not the flange of rail when spraying；
After the completion of first step spraying, rail transporting to processing line carries out saw and bores processing；
Saw bores the rail transporting after processing to second step spray station；
Upset rail causes rail to stand upside down, and clamps rail and second step spraying is carried out to rail, second step sprays rail when spraying
Bottom and remaining part, complete the spraying of rail tunneling boring；
After the completion of the spraying of rail tunneling boring, rail is transported and delivered by the way of rail stands upside down.
First step spraying is carried out to rail present invention preferably employs the upright mode of rail, the first step sprays rail head when spraying
And the web of the rail；Second step sprays the flange of rail when spraying.
The beneficial effects of the invention are as follows：Using two step spraying processes, rear flange of rail part is not contacted the flange of rail with roller-way upwards, is oriented to
Contact point is not contacted with the flange of rail, can effectively protect flange of rail coating, solve subway rail Rail Production line can not operation problem.
Brief description of the drawings
Fig. 1 is when rail stands upside down and roller-way cooperation schematic diagram；
Parts, position and numbering in figure：1- rail heads, the 2- webs of the rail, the 3- flanges of rail, 4- roller-ways.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
By taking certain beam-and-rail factory production line as an example, normal rolling process is in the prior art：Steel rail universal rolling → roll-type
Aligning → surface quality inspection → ultrasonic examination → bidirectional hydraulic, which is mended, rectifys → on-line spray → processing scroll saw brill processing → stand
Close steel → magnetic and hang → stacking.
After process using the present invention, on-line spray is sprayed for the first step, and the flange of rail is not sprayed now；Set up offline spray
Technique is applied, idiographic flow is：Stack position → magnetic hangs → stand → roller-way → double steel → rail head, web of the rail clamping → flange of rail spraying → installation
The upward entrucking fastener → handling of the flange of rail → entrucking delivery.
As shown in figure 1, the flange of rail 3 is upward when the present invention is sprayed offline, the part of the flange of rail 3 is not contacted with roller-way 4, is oriented to contact point
Do not contacted with the flange of rail 3, can effectively protect flange of rail coating.
Advantages of the present invention：Flange of rail partial coating can be adequately protected；Solving subway rail can not make in Rail Production line
The problem of industry.Shortcoming：Guiding mechanism will be redesigned, and otherwise rail easily falls；Need to use the entrucking button that the special flange of rail is upward
Part, cost has certain rising.
