Screw device for high-adjusting a track span
Spindle device for the height adjustment and alignment of tracks on a substructure, having a transverse cantilever which is fixed to an elongate nut adjustable in height on a height adjustment spindle and which engages under the rail and which is formed as a horizontal spindle plate which is mounted on the elongate nut pivotably about a horizontal axis and on which a slide provided with a clamping mount device for the rail foot is displaceable by means of a second spindle device transverse to the height adjustment spindle.
1. A spindle device for height adjustment and alignment of tracks on a substructure, comprising:
a height adjustment spindle;
an elongate nut being adjustable in height on said height adjustment spindle;
a transverse cantilever which is fixed to said elongate nut, said transverse cantilever being engageable under a rail, said transverse cantilever being formed as a horizontal spindle plate, said horizontal plate being mounted on the elongate nut and pivotable about a horizontal axis;
a second spindle device transverse to the height adjustment spindle; and
a slide provided with a clamping mount device for a rail foot, said slide being fixed to said second spindle device, said slide being displaceable on said transverse cantilever by longitudinal adjustment of said second spindle device.
2. A spindle device according to claim 1 , wherein the slide comprises a ribbed plate provided with guide rails encompassing the horizontal spindle plate with a clamping hook and a rail foot screw clamp.
3. A spindle device according to claim 1 , wherein a rigid horizontal spindle penetrating a rest on the horizontal spindle plate is fixed to the slide and is displaceable by means of adjusting nuts abutting the rest on both sides along its longitudinal axis.
4. A spindle device according to claim 2 , wherein the clamping hook is removable above the ribbed plate.
5. A spindle device according to claim 4 , wherein the clamping hook is formed by a screw for a clamping plate overlapping the rail foot.
6. A spindle device according to claim 4 , wherein the second spindle device is detachably fixed both to the slide and to the horizontal spindle plate.
7. A spindle device according to claim 1 , wherein the horizontal spindle plate includes a fixable horizontal pivot joint.
8. A spindle device according to claim 1 , wherein the elongate nut substantially overlaps the height adjustment spindle in order to increase its rigidity.
9. A spindle device according to claim 1 , further including support rails, each of said support rails for the height adjustment spindle, said support rails being fixed so as to rest on the track substructure.
10. A spindle device according to claim 9 , wherein the support rails are angle rails oriented opposite to one another having projecting abutment flanges for the height adjustment spindles or are U-shaped profiles.
11. A spindle device according to claim 1 , wherein a standing angle is infinitely variable.
