Abstract
The invention discloses an induction heating device used for rail heat treatment, belongs to the technology of power electronics in rail engineering machinery, and is used for performing heat treatment on a rail when the rail is laid and maintained. In an attached drawing, after the rail (8) is heated, once an inserting/withdrawing end (4) is withdrawn, a lifting end (6) can lift, the rail (8) can walk out a coil formed by coil sections (1), and then the heat treatment is performed on the rail (8).
Description
Technical field
The invention belongs to the Power Electronic Technique in the railway engineering machinery, when being used for rail and laying and during the rail maintenance rail is heat-treated.
Background technology
Beijing is to the railway in Guangzhou now, Xi'an is to the high-speed railway in Zhengzhou, it is the seamless rail that is welded into by rail one by one, to rail be heat-treated after welding is good, present heat treatment method is to adopt acetylene and oxygen combustion heating, handles then, and the shortcoming of technology is to use inconvenience now, handling poor, quality stability is poor.
Present induction heating apparatus is by induction heating power output intermediate frequency or the high frequency electric input to load coil, method to the workpiece heating is workpiece to be put into coil from the coil mouth of load coil heat, if give from Nanjing to the middle a bit of heating of Pekinese's rail, do not cut off in the middle of not allowing again, obviously can't put into coil, present induction heating equipment another one deficiency is, can only travelling workpiece in load coil, can not make workpiece in load coil by mobile device.
Summary of the invention
The objective of the invention is to overcome above shortcoming, design a kind of induction heating apparatus that is installed on the engineering rail car, load coil is designed to opening shape, makes things convenient for rail to put into heating.
The technical solution adopted for the present invention to solve the technical problems is: the induction heating power that is installed as the rail heating on engineering rail car, load coil is an open stich, and the winding head (2) on the coil segment of open stich (1) is to compress with oil cylinder or cylinder (3) to do electrical connection.
The invention has the beneficial effects as follows: make the heat treatment of rail convenient, ensure the quality of products easily.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the view that the vehicle-mounted eddy-current heating in the vehicle-mounted induction heating apparatus is used a face of open stich
The specific embodiment
The induction heating power of promising rail heating is installed on engineering rail car, the load coil that induction heating power is electrically connected is that open stich also is installed on the engineering rail car, two winding heads (2) are the opening parts of open stich among Fig. 1, open stich is made up of the coil segment (1) of open stich, present load coil generally by the centre can water flowing the copper pipe coiling form, this is called rigid line, can certainly adopt flexible cord, winding head (2) on the coil segment of open stich (1) is to compress with oil cylinder or cylinder (3) to do electrical connection, what the coil segment of open stich (1) had is fixed on the lift side (6), the insertion that is fixed on that the coil segment of open stich (1) has is extracted on the end (4), it is to drive the action of finishing insertion and extracting by oil cylinder or cylinder (5) that end (4) is extracted in insertion, after insertion is extracted end (4) and is extracted, lift side (6) descends by oil cylinder or cylinder (7), just can put into coil to rail (8), after end (4) insertion is extracted in insertion, compress winding head (2) with oil cylinder or cylinder (3) again, just can switch on and heat to rail (8).Fixed end (9) is fixed on the engineering rail car, has just reached the foregoing invention purpose.
If with oil cylinder is to drive with oil pump, if be to drive with air pump with cylinder.(11) be felt pad.Water nozzle (10) is water receiving pipe in use, is load coil water flowing heat radiation.
Engineering rail car is the mature technology of popularizing, and it will be apparent to those skilled in the art that.
Induction heating power is the mature technology of popularizing, and it will be apparent to those skilled in the art that.
The present invention is the simple combination of two universal mature technologies, and open stich is an one-off design.
Explanation of nouns
Engineering rail car--can walk on-the rail, can be self-powered, also can be to be pulled, and is used for construction of railways.
Heat treatment---the technician that learned metal processing has correct concept.
Induction heating power--the factory of-China production induction heating power is many, is used for the melting of iron and steel, the heat treatment of product or workpiece etc.Induction heating power and load coil have been formed induction heating apparatus.
