Description
Technical field
The utility model is related to rail welding field, more particularly to a kind of rail welding structure.
Background technology
Mobile flash welding is typically all used for field construction and used, and then all uses stationary welding machine, power supply is three-phase the weldering base of the rail
Secondary commutation, the end of the nineties in last century is purchased from Switzerland Su Laite mostly.Due to the non-pure direct current of the power supply, welding quality is also
It is unstable, it is only slightly stronger than AC power.But in the process ruggedness test and appraisal in every year（Drop weight test）It is there is segment occurred broken rail to show more
As, and irregular follow.All it is in vast and hazy and coincidence the several weldering bases of the rail of China ten.
Broken rail be because workpiece is defective, the phenomenon of defect be all the faying face of welding with the presence of greyness, cause greyness
Main cause be then by non-pure dc source and AC power trigger and.
Current rail welding machine electrode holder compact form is all upper and lower pressure, i.e., two electrodes 3 ' are clamped in rail top 1 ' and the flange of rail 2 '
Part（Except movable type）See Fig. 1.
Due to rail top depressed position conductive area and flange of rail compression area it is completely different, so easily there is flange of rail superfusion
And rail top melts not enough.
Utility model content
The purpose of this utility model is to provide a kind of rail welding structure, and electrode compression point is in the centre position of rail,
The distributing homogeneity of welding current and the uniformity of electric current transmission speed are obtained for and significantly improved.
In order to realize the above object the utility model is achieved through the following technical solutions：
A kind of rail welding structure, for welded rails, described rail is included：The web of the rail, the rail being arranged at the top of the web of the rail
The flange of rail of web of the rail bottom is pushed up and be arranged on, is characterized in, comprising：
A pair first clamping electrodes, it is clamped in the web of the rail both sides of an one steel rail；
A pair second clamping electrodes, it is clamped in the web of the rail both sides of another one steel rail；
The source of welding current, its both positive and negative polarity connects first and second clamping electrode respectively；
The electric current of the source of welding current is transmitted at rail welding by first and second described clamping electrode so that the welding of rail
Interface end produces arc light and welded.
First and second described clamping electrode is made of red copper material.
The described source of welding current is medium frequency inverter dc source.
Described medium frequency inverter dc source is connected comprising medium frequency inverter frequency converter and with medium frequency inverter converter circuit
Intermediate-frequency transformer DC rectifier circuit, the output end connection first of the intermediate-frequency transformer DC rectifier circuit clamps electrode and the
Two clamp electrode.
The utility model compared with prior art, with advantages below：
The utility model electrode compression point is in the centre position of rail, distributing homogeneity and the electric current transmission of welding current
The uniformity of speed, which is obtained for, significantly to be improved.

Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is done and further explained
State.
As shown in Figure 3,4, a kind of rail welding structure, for welded rails 1, described rail 1 is included：The web of the rail 11, set
The rail top 12 at the top of the web of the rail 11 and the flange of rail 13 for being arranged on web of the rail bottom are put, the welding structure is included：A pair first clamping electricity
Pole 2, it is clamped in the both sides of the web of the rail 11 of an one steel rail；A pair second clamping electrodes 3, it is clamped in the web of the rail two of another one steel rail
Side；The source of welding current 4, its both positive and negative polarity connects first and second clamping electrode respectively；Described first and second clamps electrode by the source of welding current
Electric current be transmitted at rail welding so that the welding junction end of rail produces arc light and simultaneously welded.
In a particular embodiment, first and second above-mentioned clamping electrode is made of red copper material.
The above-mentioned source of welding current is medium frequency inverter dc source.
Above-mentioned medium frequency inverter dc source is connected comprising medium frequency inverter frequency converter and with medium frequency inverter converter circuit
Intermediate-frequency transformer DC rectifier circuit, the output end connection first of the intermediate-frequency transformer DC rectifier circuit clamps electrode and the
Two clamp electrode.Medium frequency inverter dc source works for three-phase input, by being rectified into direct current, the exchange frequency that inversion is 1KHZ
Rate, then by transformer pressure-reducing, then by rectifying tube rectification, just forms very pure direct current.
When the utility model is applied, welding structure is used cooperatively with rail welding machine, a pair first clamping electrodes 2 are by welding rail
Machine is clipped on an one steel rail, and a pair second clamping electrodes 3 are clipped on another one steel rail by rail welding machine, the docking of two one steel rails, in
The electric current of frequency inversion direct current power supply output is transmitted on two one steel rails for needing to weld by first and second electrode, while in rail
Welding junction end produce arc light and glisten so that two one steel rails are integrally welded.
In summary, a kind of rail welding structure of the utility model, electrode compression point is in the centre position of rail, welding
The distributing homogeneity of electric current and the uniformity of electric current transmission speed are obtained for and significantly improved.
Although content of the present utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on
The description stated is not considered as to limitation of the present utility model.After those skilled in the art have read the above, for
A variety of modifications and substitutions of the present utility model all will be apparent.Therefore, protection domain of the present utility model should be by appended
