The utility model provides a kind of auxiliary fixing device for rail tensor, comprise rail, hydraulic pressure extension rod, wedge seat, upper fixed seat, stop screw, left limit block, right limit block, spacing guide pillar, described rail is fixed with a pair wedge seat, described hydraulic pressure extension rod is fixed between wedge seat by bearing pin, the side of described wedge seat is auxiliary is fixed with a upper fixed seat, fixed seat is " several " shape structure, two sides are also provided with spacing hole, horizontal both sides upper surface is also provided with spacing edge-cut, described left limit block one side is consistent with the side profile of rail, upper surface is also fixed with a spacing guide pillar, described spacing guide pillar inserts in spacing edge-cut, described right limit block is consistent with left limit block structure, symmetrical, described stop screw coordinates with spacing hole, rotary stopper screw is to regulate a left side for left limit block and right limit block, right position.
Further, fixed seat is hard alloy steel, and inner surface is high-precision flat sliding surface, and seamed edge place is provided with fillet, in order to protect the complete of the upper surface of rail, is not produced when fastening devices applies external force and damages.
Further, described spacing hole is screwed hole, and stop screw coordinates with spacing hole, closely cooperates, and makes two limited block clamping rail.
Further, described spacing edge-cut is through hole, length between 3.5cm-5.5cm, after rail and right limit block and left limit block closely cooperate, certain space is also left in spacing guide pillar distance spacing edge-cut side, better makes right limit block and increasing friction force between left limit block and rail.
Further, the upper part of described spacing guide pillar is provided with screw thread, and bottom is smooth cylinder, with spacing edge-cut interference fit.
Further, described left limit block is metal material, the surface contacted is matsurface, increases the frictional force between rail side with rail, makes fixing more stable.
The utility model provides a kind of auxiliary fixing device for rail tensor, its beneficial effect is: the utility model arranges a fastening devices by assisting at two fixed ends of rail tensor, the work that rail tensor can be stable is guaranteed by the spacing fixing mode of secondary, have easy for installation, use flexibly, solve that existing rail tensor occurs by wearing and tearing, overload overtired and slippage that is that cause.
