Signal is replaced by with rail section, the specific process flow of engineering truck is as follows：

(1) hurt rail section insertion joint rail section, is cut.Engineering truck drives to hurt rail section on the line, is parked in hurt point At front 3m to 4m.Hurt point both sides length as defined in circuit determines two cut points.Rear chassis carriage back door open, it is sliding Platform support wheel rolls on circuit rail, supports slide unit rear end, slide unit is stretched out backward, its rear end is crossed cutting below Point.Three-dimensional mechanically moving hand starting afterwards, by longitudinally, laterally, stand to displacement combine, manipulator clamping jaw is reached and is clamped and cut Cutting mill grip shank, afterwards manipulator cutting machine is sling and is moved to above rail cut point, start cutter plate motor, Manipulator descending at slow speed, cutter plate cut off rail.Then manipulator cuts rail in another cut point with cutting machine It is disconnected, between two cut points, it is formed a rail section with hurt separated with circuit rail.Manipulator will with cutting machine It puts back to original place on slide unit.Manipulator is moved again at hurt rail section, is picked up and placed on one side, and vacates joint rail fragment position. Manipulator is returned at slide unit, picks up the joint rail section being placed on slide unit, and the joint rail section is displaced into circuit rail two cuts Between cutpoint.

(2) rail, is drawn to rail.Manipulator clamping jaw is reached and clamped to rail fixture grip shank, rail fixture will be sling and be moved Move to above a cut point, and make to be in rail folder ambilateral web of the rail pressure head on rail two sides, general who has surrendered's web of the rail pressure under manipulator Head alignment steel rail web, while make folder beam-and-rail longitudinal centre line alignment cutting seam；Start drawing cylinder, the contracting of drawing cylinder piston rod Return, the web of the rail pressure head of both sides is pressed on the web of the rail of former circuit rail and joint rail section so that the cross face of two rails aligns, and draws Locking oil cylinder continues pressurize.When starting drawing cylinder, manipulator is set laterally to be in quick condition by control system.Then open The distance between dynamic pressure arm skateboard tank, adjustment both ends pressure arm, the web of the rail of former circuit rail and joint rail that both ends clamp Pressure head, just force the distance between two rail end faces to change, until distance is adjusted to meet defined weld width value, arrive This is completed to rail process procedure.

(3) rail, is welded.Manipulator clamping jaw is unclamped to rail fixture, then clamps the grip shank of automatic arc welding machine, by welding machine Movement is transposed to above rail fixture.Start automatic welding program, by former circuit rail and joint rail by the flange of rail to rail head by Layer welds together.After welding, the web of the rail at the end to the drawing cylinder pressure release on rail fixture pressure arm slide plate end, will be made immediately Pressure head unclamps rail, while pressure arm skateboard tank promotes pressure arm slide plate to bead direction, and the pressure arm inner end on the slide plate pushes away knurl Knife pushes through weld seam, and the overlap of rail head top surface and side is bulldozed.Manipulator clamping automatic arc welding machine, welding machine is put back on slide unit Original position.Manipulator is returned to rail fixture, is clamped to rail fixture grip shank, manipulator laterally switchs to quick condition, to rail Drawing cylinder piston rod on fixture stretches out, and makes to space out to the ambilateral web of the rail pressure head of rail folder, this distance is more than rail rail Head width so that manipulator will can lift to rail fixture, and will be transplanted on to rail fixture on second cut point.Repeat process 2. 3. link welds second weld seam with process links, manipulator is put back into cunning by automatic arc welding machine and to rail fixture afterwards Origin-location on platform.

(4), polishing rail head weld seam.Manipulator clamping imitates type sander grip shank, and sander is placed individually into two welderings At seam, polish rail head top surface and side.The rail head fixture at sander both ends clamps the rail head of weld seam both sides during operation, makes sander It is fixed on rail.Start turning motor, inner frame does semicircle under just arc guide rail between inside and outside wall board constrains around rail head Week rotates；The dynamic chi contact for the linear displacement transducer being now fixed on lining, withstands on rail head initial surface, in semicircle The distance that each point on rail head top surface and side arrives inner frame center is measured during rotating in week in real time；Start reciprocating motor Afterwards, bistrique balladeur train moves back and forth on draw-in bar, and moving range is to make grinding head grinding wheel, can be in the one fixed width of inswept weld seam both sides Rail head surface；Motor is fed simultaneously under the control of range data that linear displacement transducer export, driving lift planker do into To movement.Lift the grinding head motor on planker and drive emery wheel rotation, abrasive wheel end face enters to the rail head top surface of welded seam area and side Row grinding.Due to abrasive wheel end face position and linear displacement transducer dynamic chi contact position, be corresponding, weld metal zone all the time Shape after the grinding of domain is just consistent with the shape of rail head initial surface, is exactly to welded seam area, according to rail head original in other words Beginning surface configuration carries out imitative type polishing.After weld seam is all polished at two, imitative type sander is put back on slide unit former by manipulator Come position.

(5), weld seam is heat-treated.Manipulator clamping jaw reaches and clamps the grip shank of intermediate frequency heater, by intermediate frequency heater To sling and be moved to above a weld seam, manipulator declines, and the folder rail pressure head of intermediate frequency heater both sides is in rail two sides, and Steel rail web is directed at, while induction coil longitudinal center is directed at weld seam；Start 4 folder cylinder of rail of heater frame both sides, The piston rod for pressing from both sides cylinder of rail stretches out, and intermediate frequency heater is fixed on the web of the rail of rail both sides in the folder rail pressure crown of piston rod front end On rail.Actuating coil oil cylinder, coil cylinder piston rod stretch out, and make two induction coils from rail both sides close to rail.Connect Logical intermediate frequency power supply, intermediate frequency output transformer send out electric current to induction coil, heated weld seam line regions, weld seam are completed by technological parameter Heat treatment.After, intermediate frequency heater is put back into origin-location on slide unit by manipulator.

(6) hurt rail section, is reclaimed.The hurt rail section that manipulator clamping is cut down, is placed on slide unit and originally put Put the position of joint rail section.Slide unit is returned to inside chassis afterwards, and chassis carriage back door is closed, and chassis traveling is left operation and showed .So far the work of processing existing line hurt rail section is completed.

A kind of embodiment of the present utility model is these are only, is not limited to the utility model, it is all in the utility model All any modification, equivalent and improvement done within thinking and principle etc., be both contained in the scope of protection of the utility model it It is interior.
