Abstract
A hinged derail is provided with an adjustment assembly for adjusting the position of the hinge pin relative to the rail. The hinged derail is adjustable to provide for proper alignment of the deflecting block with the top surface of a rail for a variety of rail heights. In a preferred embodiment, the adjustment assembly includes a pair of rotatable adjustment flanges which support the hinge pin in an eccentric fashion. Rotation of the adjustment flanges changes the vertical position of the hinge pin. In accordance with another aspect of the invention, an actuating assembly is provided for operatively associating a power actuator with the derail shoe.
Claims14
A derailing device for use with a rail that can be a height of a plurality of different heights, the derailing device comprising:
- a derail shoe including a deflecting block for deflecting an oncoming wheel of a rail vehicle;
- a base for securing the derail shoe for movement relative to the rail, the deflecting block pivoting with respect to the base about a pivot axis;
- pivot adjustment means for permitting adjustment of the position of the pivot axis relative to the base;
- and
- wherein the derail shoe is pivotally associated with the base through a hinge pin and wherein the pivot adjustment means comprises an adjustment flange for changing the position of the hinge pin, the adjustment flange adapted to be rotatable adjusted relative to the base about an adjusting axis adjacent to the pivot axis.
A derailing device for use with a rail that can be a height of a plurality of different heights, comprising:
- a derail shoe including deflecting block for engaging the wheel of a rail vehicle, the deflecting block including a bottom surface for engaging a top surface of the rail;
- a base for securing the derail shoe for movement relative to the rail, the deflecting block pivoting with respect to the base about a pivot axis form a deployed position, in which the bottom surface engages the top surface of the rail, to a retracted position, in which the derail shoe is removed from the rail;
- an adjustment assembly for permitting an operator to adjust the position of the pivot axis relative to the rail such that the bottom surface of the deflecting block may be selectively aligned with different sizes of rails;
- and
- wherein the derail shoe is pivotally associated with the base through a hinge pin and wherein adjustment assembly comprises an adjustment flange for changing the position of the hinge pin, the adjustment flange adapted to be rotatable adjusted relative to the base about an adjusting axis adjacent to the pivot axis.
A derailing device for use with a rail that can be a size of a plurality of different sizes, comprising:
- a derail shoe including deflecting block for engaging a wheel of a rail vehicle, the deflecting block including a bottom surface for engaging a top surface of the rail;
- a base for securing the derail shoe for movement relative to the rail, the base including a pair of mounting plates for securing the base to ties beneath the rail, each mounting plate being secured to a substantially perpendicular side plate extending therefrom, each side plate having formed therein a journal;
- the derail shoe being pivotally associated with the base through a hinge pin to pivot about a pivot axis from a deployed position, in which the bottom surface engages the top surface of the rail, to a retracted position, in which the derail shoe is removed from the rail;
- and
- an adjustment assembly cooperating with the journals in the side plates, for permitting an operator to adjust the position of the pivot axis with respect to the rail.
