Locked-axle spring compression system and method
A locked-axle spring compression system and method configured to raise a rail vehicle wheel off a rail and transport the raised wheel along a rail is presented. In one embodiment, the present disclosure discloses a system that can raise the locked-axle rail wheel off the rail and allowing the locked-axle train to be transported off the main line. One or more coil springs can be disposed between the truck frame and the journal box to distribute the weight of the train and forces acting thereon. The present disclosure provides a technological solution missing from conventional systems by at least providing a platform for an actuator configured to exert a force on one or more train elements to compress the coil springs and allow the locked-axle wheel to be raised off a surface (e.g., railroad track rail), by overcoming the coil spring pressure to raise the wheel off the rail.
1 . A method of lifting a locked-axle wheel by compressing a coil spring, comprising:
coupling a locked-axle spring compression system having a base plate, an extender, and an actuator to a vehicle frame proximate a locked-axle rail wheel;
exerting a force, via the actuator, on a journal box operably coupled to the vehicle frame; and
compressing a coil spring disposed proximate the journal box to raise the locked-axle rail wheel off a surface.
2 . The method of claim 1 , further comprising installing a spacer between the vehicle frame and a second journal box.
3 . The method of claim 1 , wherein the actuator is a hydraulic cylinder.
4 . The method of claim 1 , wherein the locked-axle spring compression system further includes a gauge box coupled to the actuator.
5 . The method of claim 1 , wherein at least one actuator hole is disposed through the base plate and configured to receive an actuator screw or stud.
6 . The method of claim 1 , wherein the actuator is disposed between the base plate and the vehicle frame.
7 . The method of claim 1 , wherein the actuator is coupled to the base plate with a ram end of the actuator pointed towards the vehicle frame.
8 . The method of claim 1 , wherein the actuator lifts the journal box toward the vehicle frame, causing the coil spring to compress.
9 . The method of claim 1 , wherein a bolt is disposed through a bolt hole of the base plate and a bolt channel of the extender, and into threaded holes of the vehicle frame.
10 . The method of claim 1 , further comprising removing j-block bolts coupling a j-block to the vehicle frame and using j-block bolt holes in the vehicle frame to couple the base plate to the vehicle frame.
11 . The method of claim 10 , further comprising using the removed j-block as a spacer disposed between the journal box and the vehicle frame.
12 . The method of claim 1 , further comprising installing a spacer between the vehicle frame and a second journal box.
13 . The method of claim 1 , wherein the actuator is a hydraulic cylinder.
14 . The method of claim 1 , wherein the locked-axle spring compression system further includes a gauge box coupled to the actuator.
15 . The method of claim 1 , wherein at least one actuator hole is disposed through the base plate and configured to receive an actuator screw or stud.
16 . The method of claim 1 , wherein the actuator is disposed between the base plate and the vehicle frame.
17 . The method of claim 1 , wherein the actuator is coupled to the base plate with a ram end of the actuator pointed towards the vehicle frame.
18 . The method of claim 1 , wherein the actuator lifts the journal box toward the vehicle frame, causing the coil spring to compress.
19 . The method of claim 1 , wherein a bolt is disposed through a bolt hole of the base plate and a bolt channel of the extender, and into threaded holes of the vehicle frame.
20 . A method of lifting a locked-axle wheel by compressing a coil spring, comprising:
coupling a platform having a base plate, an extender, and an actuator to a vehicle frame proximate a locked-axle rail wheel;
operably coupling a pump to a gauge box indicating the pressure of each actuator deployed;
operating the actuator, via the pump, to exert a force on a journal box operably coupled to the vehicle frame; and
compressing a coil spring disposed proximate the journal box to raise the locked-axle rail wheel off a surface.
