Description
Technical field
The utility model is related to arrive railway signal detection technique field more particularly to a kind of cladding alloy-layer elevation carrection dress
It sets.
Background technology
Track circuit is two one steel rails using rail track as conductor, and both ends are subject to mechanical insulated or electric insulation, connect
The circuit that upper power transmission and power receiving equipment are constituted.The main function of track circuit is supervision train position and transmission running information.Rail
Road circuit is usually made of main elements such as rail, track insulation, rail end bond wire, lead wire, power equipment and power receiving equipments.
Rail includes from top to bottom rail head, the web of the rail and the flange of rail, and rail head includes rail head top surface, rail head side and rail head bottom surface；Wherein rail head
Top surface, i.e. rail tread and rail head side are in the most contact with train wheel, serious wear.
When track circuit is complete and without train occupation, AC power is transmitted to receiving end, track by sending end through rail
Relay energized, signal indicate this track circuit without the vehicle free time；When train occupation track circuit, two one steel rails are through same root vehicle
Two wheels on axis and branch is connected, two one steel rail voltages are less than track relay terminal voltage working value, and track relay is fallen
Under, signal indicates that this track has vehicle occupancy.Track circuit shunting badness is when train is in track circuit section occupancy, respective segments
Track relay be still in pick up or when fall state when inhaling, at this time on corresponding signal lamp and console can mistake display it is green
Lamp or white lamp, lose the audit function to track section seizure condition, which is known as shunting badness.When this thing happens
When, train operator and making station control personnel will be mistakenly considered to occupy without vehicle in the section, be driven a vehicle and handled into dataway operation, from
And cause the serious driving accidents such as train collision, derailing.The place for be easy to causeing track circuit shunting badness be mainly station track,
The trains such as safety line, industrial siding, track switch and branch-cut bridge it is long-term it is less by section or the serious area of corrosivity such as acid rain, steel
Rail rail surface severe oxidation gets rusty, when train is getting rusty on serious rail when driving, although train wheel with rail contact not
Conducting, leads to shunting badness.Using rail cladding alloy technology, in Rail Surface part melting and coating anti-rust wear-resistant alloy, alloy with
Base material is metallurgical binding, and Rail Surface is made to obtain antirust cladding alloy-layer wear-resisting, against corrosion.When train wheel is contacted with alloy-layer,
It is to ensure that vehicle is in the conduction state always with rail, to solve the problems, such as track circuit shunting badness.Rail cladding
Alloy is to be constructed in Railway Site by cladding machine, and live rail is due to abrasion, and there are overlap, the abrasion of top surface circular arc in rail head side
Variation, therefore there is no benchmark；In addition rail head top surface itself is multi-section circular arc composition, thus cladding alloy-layer position is practical at the scene
It can not simply be determined in operation.Due to too low, scene also can not simply measure alloy layer height after cladding.
The position of cladding alloy-layer is to roll contact theory according to wheel track to determine, it is ensured that wheel effectively connects with alloy
It touches.If alloy strip position is deviateed, it is possible to wheel occur in positions such as train turn, track switches and alloy is discontiguous
Situation leads to track circuit shunting badness.Cladding alloy height is also critically important, excessively high to alloy wear-resisting, service life and train
Braking distance etc. all has a major impact.And the existing survey tool about live rail size of railway can not solve the problems, such as this.
Publication No. CN 205420551U, publication date are that on 08 03rd, 2016 Chinese patent literature discloses one kind
Laser cladding powder powdering measurer for thickness, it is characterised in that：With a pair by front and back to the guide rail for keeping flat setting, in guide rail
On be uprightly fitted with one and can be done along guide rail front and back to the montant moved, connect at the top of montant equipped with one by left and right to horizontal
Telescopic rod, the other end of telescopic rod connect downwards equipped with one pair by vertical main scale, vernier scale and vernier locking device group
At vernier caliper, the lower ruler face of wherein main scale is equal to or slightly higher than the bottom surface of guide rail, and in the lower part of vernier scale, even there are one rulers
Set is coated with a ruler by left and right to horizontal in ruler set.
Laser cladding powder powdering measurer for thickness disclosed in the patent document, have one it is secondary by front and back to keeping flat setting
Guide rail cause entirely to survey using guide rail as the base surface of entire measurement process, and live ground out-of-flatness of rail cladding itself
It is poor to measure process stability, has seriously affected the accuracy of rail cladding alloy-layer elevation carrection, and measurement point is more single.
