Fig. 2 is the plan structure schematic diagram among Fig. 1.
Be labeled as among the figure: lifting driving box 1, rigid support axle 2, holddown spring 3, horizontal hold-down roller 4, horizontal transmission roller 5, vertical smoothing roll 6, web of the rail smoothing roll 7, adjustment leading screw 8, vertical roll unit 9, pedestal 10, adjustment leading screw 11, rail 12.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1 and shown in Figure 2, high temperature rail straghtener of the present utility model, comprise pedestal 10, pedestal 10 is provided with the horizontal smoothing roll of at least two groups that acts on rail 12 upper and lower surfaces, vertical smoothing roll 6 of at least two groups that acts on rail 12 flange of rail sides and at least one group of web of the rail smoothing roll 7 that acts on rail 12 web of the rail sides, and at least one group of horizontal smoothing roll and at least one group of vertical smoothing roll 6 are arranged at the front end of web of the rail smoothing roll 7 on the throughput direction of rail 12.Horizontal smoothing roll acts on the upper and lower surface of rail 12, and vertically smoothing roll 6 acts on the left and right side of rail 12, and web of the rail smoothing roll 7 acts on the web of the rail place of rail 12.When straightening of kinked rail 12, the horizontal smoothing roll of at least two groups cooperates the crooked up and down of straightening of kinked rail 12 with web of the rail smoothing roll 7, and the vertical smoothing roll 6 of at least two groups cooperates bending right and left of straightening of kinked rail 12 with web of the rail smoothing roll 7.At this moment, 7 pairs of rail 12 of web of the rail smoothing roll crooked up and down with bend right and left that to align role less, 7 of web of the rail smoothing rolls play auxiliary aligning effect, it mainly is to be used for pressing the hot saw on the rail 12 to cut overlap.During aligning, rail 12 about, left and right directions is positioned on the horizontal line, can avoid rail 12 when high-speed cruising, the scuffing of 7 pairs of rail of web of the rail smoothing roll can be improved the quality of products greatly.
In the superincumbent embodiment, the horizontal smoothing roll of at least two groups, the vertical smoothing roll 6 of at least two groups can be arranged arbitrarily on the throughput direction of rail 12 with at least one group of web of the rail smoothing roll 7, as arranging the horizontal smoothing roll of at least two groups earlier, arrange the vertical smoothing roll 6 of at least two groups again, and then the order of arranging at least one group of web of the rail smoothing roll 7, or arrange the horizontal smoothing roll of at least two groups earlier, arrange at least one group of web of the rail smoothing roll 7 again, and then arrange the order of the vertical smoothing roll 6 of at least two groups.As preferred mode, the horizontal smoothing roll of at least two groups is separately positioned on the front end and the rear end of web of the rail smoothing roll 7; The vertical smoothing roll 6 of at least two groups is separately positioned on the front end and the rear end of web of the rail smoothing roll 7.Can realize the crooked up and down of rail 12 better and bend right and left aligning.
In the above embodiment, horizontal smoothing roll, vertical smoothing roll 6 all can be set to many groups with web of the rail smoothing roll 7, in order to make whole straightening mechanism simple in structure, described horizontal smoothing roll, vertical smoothing roll 6 are respectively two groups, web of the rail smoothing roll 7 is one group, on pedestal 10 successively according to one group of horizontal smoothing roll, one group of vertical smoothing roll 6, web of the rail smoothing roll 7, another organizes vertical smoothing roll 6, another organizes the order setting of horizontal smoothing roll.As shown in Figure 1, when straightening of kinked rail 12, at first rail 12 is imported from throughput direction horizontal smoothing roll foremost, from the vertical smoothing roll 6 of front end through behind the web of the rail smoothing roll 7 again behind the vertical smoothing roll 6 of rear end from the horizontal smoothing roll output of rearmost end, two groups of horizontal smoothing rolls cooperate the bending up and down of straightening of kinked rail 12 with web of the rail smoothing roll 7; Two groups of vertical smoothing rolls 6 cooperate with web of the rail smoothing roll 7 and are used for bending right and left of straightening of kinked rail 12, and simultaneously, web of the rail smoothing roll 7 presses the hot saw on the rail 12 to cut overlap.This is simple in structure, has realized the crooked up and down of rail 12 simultaneously well and bent right and left aligning.
Regulate the aperture up and down of horizontal smoothing roll for convenience, described every group of horizontal smoothing roll comprises a horizontal transmission roller 5 and a horizontal hold-down roller 4; Pedestal 10 is provided with lowering or hoisting gear, and horizontal hold-down roller 4 is arranged on the lowering or hoisting gear.Moving up and down of lowering or hoisting gear can move up and down by the horizontal hold-down roller 4 of drive, realizes the adjusting of aperture up and down of horizontal smoothing roll is used to align the rail 12 of various differing heights.And lowering or hoisting gear can adopt different version to realize, as adopting pinion and rack, chain-drive mechanism etc., as optimal way, described lowering or hoisting gear comprises the adjustment leading screw 11 that is arranged on the pedestal 10, is arranged on the lifting driving box of adjusting on the leading screw 11 1, and lifting driving box 1 bottom fixedly installs rigid support axle 2, the bearing block of horizontal hold-down roller 4 is articulated on the rigid support axle 2, is provided with holddown spring 3 between the bearing block of horizontal hold-down roller 4 and lifting driving box 1 bottom.Then by adjusting the rotation of leading screw 11, can drive lifting driving box 1 and move up and down, it is simple in structure, and is easy to adjust.And the rigid support axle 2 by being provided with, the bearing block of horizontal hold-down roller 4 is articulated on the rigid support axle 2, then horizontal hold-down roller 4 can swing up and down when aligning, and control the thrust of 4 pairs of rail 12 of horizontal hold-down roller by the pressure of regulating holddown spring 3, prevent the excessive damage that causes rail 12 of pressure.
For maintaining easily, all be arranged on the vertical roll unit 9 being removably connected with 9, two groups of vertical smoothing rolls 6 of vertical roll unit and one group of web of the rail smoothing roll 7 on the pedestal 10.When vertical smoothing roll 6 and web of the rail smoothing roll 7 can not fine work, only need a dismounting vertical roll unit 9 can process maintenance.
Regulate the left and right sides aperture of vertical smoothing roll 6, web of the rail smoothing roll 7 for convenience, vertical roll unit 9 is provided with the adjustment leading screw 8 that acts on vertical smoothing roll 6 and web of the rail smoothing roll 7 respectively.By rotate adjusting leading screw 8, can drive vertical smoothing roll 6, web of the rail smoothing roll 7 left and right horizontal move, and realize the adjusting to vertical smoothing roll 6, web of the rail smoothing roll 7 left and right sides apertures, are used to align the rail 12 of various different in width.
