TECHNICAL FIELD
The present disclosure relates generally to locked-axle rail wheels, and more specifically to a journal box coil spring compression system configured to raise and transport a locked-axle wheel.
BACKGROUND
As rail vehicles travel over a rail, they can become damaged by many hazards along the trip. Such damage can cause the rail vehicle to malfunction. One particularly troublesome malfunction is when an axle of a rail vehicle (e.g., locomotive, railcar, or other suitable vehicle) locks up and prevents the wheels of the rail vehicle from traversing a railroad track. Such condition can cause irreparable damage to the rail vehicle or even derailment. When a rail vehicle axle locks up during operation, the effect is that the main line stopped. Further, staffing is affected as the current crew will typically be released to work on another train crew or rest. After losing a train crew, a first responder must be deployed to address the locked axle. Once the locked axle is identified, another response team must be deployed to address the locked axle. The locked axle rail vehicle is then transported via various means to a service location. The train having a locked axle must then wait for another crew to arrive to transport the train to its intended destination. Such delays can impact heavy losses for a railroad operator. Moreover, the losses are compounded as it is not only the effect of a particular locked-up rail vehicle, but every other train behind that has to stop. With hundreds of locked axle events every year, the effect on railroad operations cannot be overstated.
Traditional solutions to this problem have included: hiring an “oiler” to oil the railroad track to allow the wheel to “skid” to the nearest service location, cutting the fittings, or using a crane to lift the locked-axle rail vehicle off the line. The difficulties with having an oiler on hand is the labor burden of walking with a train for miles, periodically applying oil to the wheel or track, until the service location is reached. When cutting the pinion, there are many hazards that can cause harm to the responder and the rail vehicle including under-locomotive environment hazards and weather considerations. Employing a crane adds time and expense to the process, including blocking the main line. Other train wheel dollies exist, but they typically require a crane to lift the train to position the locked-axle wheel on a dolly. Understandably, these dollies are rarely used since a rail vehicle is already being lifted with a crane, replacement of the offending axle may be just as easy.
SUMMARY
The present disclosure achieves technical advantages as 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. In one embodiment, the present disclosure discloses a system that can raise the locked-axle rail wheel off the rail with no crane, thereby allowing the train with a locked axle to be transported off the main line in a shorter period of time. A train can include a truck frame having a journal box (a/k/a captain's hat) operably coupled to the rail vehicle axle and the truck frame. 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 solves the technological problem of how to address locked-axles on a train that occur during travel.
The present disclosure provides a technological solution missing from conventional systems by at least providing a platform for an actuator (e.g., a hydraulic cylinder, jack, air bag, or other suitable lifting mechanism) 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. In one embodiment, the actuator can be coupled to a vehicle frame (e.g., a train truck frame) and exert a force away from the platform to bring about the compression of one or more coil springs. As the coil springs proximate a locked-axle rail wheel are compressed, the train weight exerted on the rail wheel is released causing the rail wheel to rise off of the surface.
The system provides the technological benefit of no longer having to use a crane or slide a locked-axle rail vehicle to the next siding or repair location. The system can be deployed within minutes to get the locomotive moving again to relieve mainline congestion.
It is an object of the invention to provide a locked-axle rail wheel spring compression system. It is a further object of the invention to provide a locked-axle spring compression system. It is a further object of the invention to provide a method of lifting a locked-axle wheel by compressing a coil spring. These and other objects are provided by at least the following embodiments.

FIG. 1 illustrates a side-view of a portion of a train wheel assembly 100, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, a journal box (a/k/a captain's hat) 102 can be the mechanical subassembly on each end of the axles under a rail vehicle (train), such as a railcar or locomotive. A train can include a truck frame 106 having a journal box 102 operably coupled to the rail vehicle axle assembly 108 and the truck frame. The rail vehicle axle assembly 108 can contain bearings and thus transfer the rail vehicle weight to the journal box 102, rail wheels 110 and rails. The bearings can be roller bearings. One or more coil springs 104 can be disposed between the truck frame 106 and the journal box 102 to distribute the weight of the train and forces acting thereon. The journal box coil springs 104 can be disposed on either side of the rail vehicle axle assembly 108 of a train. The coil spring 104 can be a helical compression spring. The coil springs 104 can ensure the proper distribution of weight to the various wheels 110 of the rail vehicle. As such the coil springs 104 impress the weight of the locomotive onto the journal box 102 and then onto the rail vehicle wheels 110.
FIG. 2A illustrates a side-view of a platform 200 of a locked-axle spring compression system, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, the platform 200 can include a base plate 202. The base plate 202 can include actuator holes 204 and bolt holes 210. In another embodiment, the platform 200 can include one or more extenders 206. The extenders 206, can include a bolt channel 208 disposed therethrough. In another embodiment, a base plate 202 can include a top side and a bottom side, with one or more bolt holes 210 disposed therethrough, an extender 206 having a bolt channel 208 can be coupled to the top side of the base plate 202, a bolt can be disposed through the bolt hole 210 from the bottom side of the base plate 202 and through the bolt channel 208. In another embodiment, all platform elements can be made of metal (e.g., ANSI 1018 steel). In another embodiment, the bolt channel 208 and the bolt hole 210 can be sized and shaped to receive a bolt therethrough. For example, the bolt channel 208 and the bolt hole 210 can be aligned to facilitate insertion of the bolt through the base plate 202 and the extender 206. In another embodiment, the extender 206 can have a length at least as long as an actuator selected for mounting on base plate 202. For example, the extender 206 can be 8.5″ long and 1.5″ wide. The extender can have a cross section of a circle, square, triangle, polygon, or other suitable shape or contour.
FIG. 2B illustrates a top-view of the platform 200 of a locked-axle spring compression system, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, the base plate 202 can be configured to receive at least one actuator 212 disposed in an actuator area proximate one or more actuator holes 204. For example, the actuator 212 can be any type of lifting mechanism, including a floor jack, bottle jack, air hydraulic jack, inflatable jack, cylinder, motorized arm, or other suitable device, and the actuator area can be contoured to accommodate an actuator 212. In another embodiment, the actuator 212 can include one or more screws on one end to couple the actuator to the base plate 202. For example, the screws can be disposed through the actuator holes 204 in base plate 202 and secured on the other side via a nut, wing nut, pin, or other suitable device. In another embodiment, the actuator 212 can include one or more studs on one end to couple the actuator to the base plate 202. For example, the studs can be disposed through the actuator holes 204 in base plate 202 without further securing the actuator 212 to the base plate 202. The extenders 206 and the actuator can be disposed proximate the edges of base plate 202, the center of base plate 202, both the edges and the center of base plate 202, or any suitable location on base plate 202.
FIG. 3A illustrates a perspective-view of an actuator 302, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, the actuator 302 can be a hydraulic cylinder (bottle jack). In one example, the hydraulic cylinder can be a jack which resembles a bottle in shape, having a cylindrical body and a neck. Within the hydraulic cylinder can be disposed a vertical lifting ram. The actuator 302 may be pneumatic, hydraulic, or work by screw action. In another embodiment, the actuator 302 can have an adaptor 306 configured to engage one or more hoses to receive a fluid, such as air, water, oil, or other suitable fluid. In the pneumatic version, in one embodiment, pressurized fluid can be used to operate the actuator. In another embodiment, the actuator 302 can be a hydraulic jack actuated by compressed air—for example, air from a compressor—instead of human work. This eliminates the need for the user to actuate the hydraulic mechanism, saving effort and potentially increasing speed. Sometimes, such jacks are also able to be operated by the manual hydraulic actuation, retaining hand operation functionality even if a source of compressed air is not available. In the hydraulic version, in another embodiment, the hydraulic ram can emerge from the body vertically by hydraulic pressure provided by a pump either on the baseplate or at a remote location via a hose (e.g., a pressure hose). For example, for lifting heavy structures the hydraulic interconnection of multiple vertical jacks through valves enables the even distribution of forces while enabling close control of the lift. In another embodiment, the screw version of the actuator works by turning a large nut running on the threaded vertical ram at the neck of the body. The nut can include gear teeth and can be generally turned by a bevel gear coupled to the body, the bevel gear being turned manually by a jack handle fitting into a socket. In another embodiment, the ram may have a second screwed ram within it, which doubles the lifting range telescopically.
FIG. 3B illustrates a top-view of a base plate 202, in accordance with one or more exemplary embodiments of the present disclosure. The base plate 202 can include multiple holes to receive one or more system components. For example, the base plate 202 can include actuator holes 204, bolt holes 210, or other suitable holes. The corresponding bolt holes 210 and actuator holes 204 can be positioned anywhere on base plate 202 to correspond with the location of a respective extender 206 or actuator 302.
FIG. 3C illustrates a perspective-view of a base plate 202 with actuators 302, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, actuators can be positioned on the base plate 202 to provide directed lift to an area. In another embodiment, the actuators 302 can be coupled to the base plate 202 to direct rams away from the base plate to lift an object away from the base plate 202. In another embodiment, the actuators 302 can be coupled to the base plate 202 to direct rams away from the base plate to push the base plate 202 away from an object. In another embodiment, when the platform is secured to a vehicle frame, the actuators 302 can push away from the base plate 202 to compress an object (e.g., coil springs of a journal box).
FIG. 4 illustrates a perspective-view of a platform of a locked-axle spring compression system coupled to a vehicle frame proximate a rail wheel 110, in accordance with one or more exemplary embodiments of the present disclosure. In one exemplary embodiment, the platform can include a base plate 202 with at least two extenders 206 disposed thereon. A bolt 402 can be disposed through the base plate 202 and each extender 206 to be screwed into one or more frame holes. For example, the vehicle frame can be a train truck frame with one or more truck jaws 404 extending therefrom. In another embodiment, a journal box 102 can be operably coupled to the truck frame with one or more openings allowing access to the truck frame or truck frame elements (e.g., truck jaws 404).
FIG. 5 illustrates a perspective-view of another platform of a locked-axle spring compression system coupled to a vehicle frame, in accordance with one or more exemplary embodiments of the present disclosure. In one exemplary embodiment, the platform can include a base plate 202 with at least four extenders 206 disposed thereon. A bolt 402 can be disposed through the base plate 202 and each extender 206 to be screwed into one or more frame holes to secure the platform to the vehicle frame. For example, the vehicle frame can be a train truck frame with one or more truck jaws extending therefrom. In another embodiment, a journal box 102 can be operably coupled to the truck frame with one or more openings allowing access to the truck frame or truck frame elements (e.g., truck jaws 404).
FIG. 6 illustrates a perspective-view of a locked-axle spring compression system coupled to a vehicle frame and hoses 602, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, the platform 200 can have at least one actuator 212 (or other lifting device) coupled thereto. In another embodiment, one or more hoses 602 can couple a gauge box 604 to the actuator 212. For example, the gauge box 604 can include one or more gauges, corresponding with each actuator 212 to monitor and apply fluid to the actuators 212. In another embodiment, the gauge box can include one or more magnets to adhere the gauge box to the train (e.g., the journal box 102). The gauges of gauge box 604 can indicate the pressure exerted or maintained by each actuator (e.g., hydraulic cylinder) 212. In another embodiment, a hose 602 can couple the gauge box 604 to an external device, such as a pump. For example, a pump can provide fluid to the gauge box 604, which can then distribute the fluid to the actuators to control the actuator.
FIG. 7 illustrates a perspective-view of a platform 200 of a locked-axle spring compression system coupled to a vehicle frame (e.g., truck frame) 702 without a journal box and axle, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, a vehicle frame 702 can include a coil spring well 704 configured to receive one end of a coil spring. The other end of the coil spring can be operably coupled to a coil spring well of a journal box 102. The truck frame 702, can also include one or more elements such as truck jaws 708. One or more pedestal liners 706 can be coupled to a face of a truck jaw 708. In another embodiment, the truck jaws 708 can include one or more threaded holes configured to receive a bolt, screw, or other threaded device. For example, the j-block bolts coupling j-blocks to the truck jaws 708 can be removed and the j-block bolt holes utilized to couple the platform 200 to the truck frame 702. In another embodiment, the j-blocks decoupled from the truck jaws 708 can be used as spacers disposed between the journal box 102 and the truck frame 702. In another embodiment, the bolts of platform 200 can be disposed through the bolt holes 210 of the base plate 202 and the bolt channels 208 of the extenders 206, and into the threaded holes of the truck jaws 708, to provide a secure coupling of the platform 202 the truck frame 702. In another embodiment one or more actuators 212 can be coupled to the platform 200 with the ram ends of the actuator 212 pointed towards the truck frame 702. In this way, in one embodiment, the platform 200 can be securely coupled to the truck frame such that operation of the actuators 212 can cause compression between the actuators 212 and the truck frame 702. For example, when fully assembled, the actuators 212 can lift the journal box 102 toward the truck frame 702, causing the coil springs disposed between the coil spring well 704 of the truck frame 702 and the coil spring well of the journal box 102 to compress, thereby overcoming the coil spring pressure exerted on the wheel to raise the wheel off the surface.
FIG. 8 illustrates a perspective-view of a platform 200 of a locked-axle spring compression system coupled to a vehicle frame with a journal box 102, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, one or more actuators 212 can be coupled to the platform 200. Hoses can be operably coupled to an adapter of each respective actuator 212. In another embodiment, when fluid is provided to the actuators 212 via the adapters, the pressure within the actuator 212 rises, causing a lifting ram 802 disposed within each actuator 212 to extend out of each actuator 212. As the lifting ram 802 rises out of a respective actuator 212, the lifting ram 802 comes into contact with a portion of the journal box 102. Since the platform 200 can be securely coupled to the truck frame 702, as the lifting ram 802 extends away from the platform 200, it pushes the journal box 102 away from the platform 200 causing compression of the coil springs proximate the platform 200.
FIG. 9 illustrates a perspective-view of a platform 200 of a locked-axle spring compression system coupled to a vehicle frame with a raised rail wheel, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, once the actuators (e.g., hydraulic cylinders 212) are actuated via fluid provided via hoses 602 coupled to a gauge box 604, the journal box 102 can be lifted away from the platform 200, causing the coil spring pressure to be overcome and lifting the rail wheel 110 off the surface, as shown in FIG. 9. In one embodiment, the rail wheel 110 can be lifted at least a half-inch (½″) off the rail to facilitate travel. For example, a wheel begins to lift off a surface at approximately 7500 psi, and at approximately 8500 psi, will raise a −9 spring to board, when a hydraulic cylinder is used.
FIG. 10 illustrates a perspective-view of a platform 200 of a locked-axle spring compression system with compressed coil springs 104, a pump 1004, and a raised rail wheel, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, a pump 1004 can be operably coupled to a gauge box 604 indicating the pressure of each actuator deployed. For example, the pump can provide fluid to the gauge box, which in turn can distribute the fluid into each actuator to increase the pressure and cause an actuator ram to extend. The gauge box 604 can include a housing, an assembly of gauges, and/or hose adapters, or any suitable configuration thereof. The pump 1004 can be a hand pump, mechanical pump, electric pump, or other suitable pump capable of providing hydraulic flow to the actuator. As the actuator lifts the journal box 102 away from the platform 200 additional strain can be placed on a second (third, etc.) journal box near the lifted journal box 102. A spacer 1002 can ensure the extra force does not damage the second journal box and or its respective axle. For example, the spacer 1002 can be positioned between the second journal box and the truck frame 702 to ensure sufficient distance between the second journal box and the truck frame to maintain the train structure. In another embodiment, the spacer 1002 can be the j-blocks previously decoupled from the truck jaws 708. In another embodiment, the spacer 1002 can be a metal component or other suitable device. In another embodiment, the wheels on either side of the locked axle can be raised, or both wheels of a locked axle can be raised by installation of a platform on both sides of the rail vehicle.
FIG. 11 illustrates a perspective-view of a platform 200 of a locked-axle spring compression system with compressed coil springs 104, a pump 1004, a spacer 1002, and a raised rail wheel 110, ready for travel, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, once the spacers are inserted proximate nearby journal boxes, the journal box 102 of a locked-axle is lifted, the coil springs 104 compressed, and the locked-axle rail wheel 110 lifted off the rail, the pump and associate pump hose can be disconnected from the gauge box 604. The hoses between the actuators 212 and the gauge box 604 can be retained to monitor the pressure of the actuators 212 as the train travels. The magnets of the gauge box 604 are strong enough to secure the gauge box 604 to the journal box 102 during travel.
FIG. 12 illustrates a side-view of a portion of a train wheel assembly with spacers 1200, in accordance with one or more exemplary embodiments of the present disclosure. In one embodiment, the spacers 1200 can include a block 1202, a retention arm 1204, and a coupler 1206. In another embodiment, the block 1202 can be a block of any size, shape, and suitable material sufficient to maintain a gap between the truck frame 702 and the journal box 102. For example, by maintaining a gap between the truck frame 702 and the journal box 102, the spacer 1200 can prevent damage to other rail vehicle components due to the raised locked-axle wheel. In another embodiment, blocks 1202 keep the coupler height from changing more than ½″. In another embodiment, a retention arm 1204 can be operably coupled to the block 1202 and the coupler 1206. The retention arm 1204 can be made of metal, plastic, or other suitable material. The coupler 1206 can be a magnet, hook, chain, or other suitable device. For example, the block 1202 is maintained in place via the retention arm 1204, secured to the rail vehicle via the coupler 1206.
