The railroad industry employs a variety of different railroad cars for transporting different materials. For example, various known railroad cars often carry large steel plates, and are sometimes called “large plate tilt railroad cars.” Known large plate tilt railroad cars are relatively heavy, include hydraulic lifting apparatus, and are relatively complicated, expensive, and require frequent maintenance. Since such large plate tilt railroad cars are relatively heavy, the amount of weight that they can carry is somewhat limited due to overall weight restrictions for railroad cars. There is a continuing need to provide large plate tilt railroad cars that can carry large plates of greater weights, and that are less complicated, less expensive, and require less maintenance.
Various embodiments of the present disclosure provide a large plate tilt railroad car having a plate support assembly. Various embodiments of the present disclosure provide a plate support assembly for a large plate tilt railroad car. In various example embodiments of the present disclosure, the plate support assembly includes a plurality of spaced-apart plate supporters connected to the deck of the railroad car. The plurality of spaced-apart plate supporters respectively include a plurality of plate holders simultaneously movable from: (a) loading positions in which one or more large plates can be loaded onto plate holders of the railroad car to (b) transit positions in which one or more large plates can be transported on the plate holders using the railroad car, and then simultaneously movable back to (a) unloading positions in which one or more large plates can be unloaded from the plate holders of the railroad car. In various embodiments, the loading and unloading positions are the same positions, although they can vary in accordance with the present disclosure. In various embodiments, the large plate tilt railroad car includes plate movement blockers connected to the plate supporters and configured to prevent longitudinal movements of the plates held by the railroad car.

Various embodiments of the present disclosure provide a large plate tilt railroad car configured to support and transport one or more large plates such as but not limited to large steel plates. Various embodiments of the present disclosure provide a plate support assembly for such large plate tilt railroad car. Various example large steel plates are used herein as a non-limiting example.
Referring now to the drawings,
The plate support assembly 100 generally includes a plurality of spaced-apart plate supporters 110a, 110b, 110c, 110d, 110e, 110f, 110g, and 110h connected to the deck 60 and that respectively include a plurality of spaced-apart plate holders 150a, 150b, 150c, 150d, 150e, 150f, 150g, and 150h. The plurality of plate holders 150a to 150h are operable to simultaneously move (and to particularly pivot) from: (a) loading/unloading positions (shown in
It should be appreciated that, as further explained below, the large steel plates are so large that they need to be transported at an angle so that they fit within the maximum outer dimensions allowed for railroad cars and the cargo that they carry (such as the maximum outer dimensions allowed by the AAR). These outer dimensions are generally indicated by the dotted lines in
More specifically, the plate support assembly 100 includes a drive assembly 300 configured to cause each of the plurality of plate holders 150a to 150h to simultaneously move from the loading/unloading positions to the transit positions, and to simultaneously move from the transit positions to the loading/unloading positions. In this illustrated example embodiment, the drive assembly 300 is actuatable by one or more powered external drive actuators (not shown) removably connectable to the drive assembly 300. In other embodiments, the drive assembly 300 is actuatable by one or more powered drive actuators (not shown) that is/are part of the railroad car 20 such as one or more drive motors mounted to or on the deck 60 of the railroad car 20.
In this illustrated example embodiment, the plate support assembly 100 includes the eight plate supporters 110a to 110h that are each driven plate supporters and that are each coupled to the drive assembly 300 (as further described below). In this example embodiment, when one or more steel plates (such as plate 25) is/are positioned on the plate holders 150a to 150h of the plate supporters 110a to 110h, the plate holders 150a to 150h of the driven plate supporters 110a to 110h can all be moved simultaneously. It should also be appreciated that the quantity of plate supporters can vary in accordance with the present disclosure. It should further be appreciated that the positions of the plate supporters can vary in accordance with the present disclosure.
In other embodiments, the plate support assembly can include two different types of plate supporters. Specifically, certain of the plate supporters can be driven plate supporters that are coupled to the drive assembly and one or more of the plate supporters are not driven, are not coupled to the drive assembly, and are thus follower plate supporters (not shown). In this example embodiment, when one or more steel plates are positioned on the plate holders of the plate supporters, the steel plate(s) cause(s) the plate holders of each of the follower plate supporters to follow the movement of the plate holders of the driven plate supporters. It should be appreciated that the follower plate supporters can include or be operable with a suitable securing mechanism (not shown) that secures the plate holders of the follower plate supporter when not in use. It should also be appreciated that the quantity of driven plate supporters and the quantity of follower plate supporters can vary in accordance with the present disclosure. It should further be appreciated that the positions of the driven plate supporters and the positions of the follower plate supporters can vary in accordance with the present disclosure.
Since all of the plate supporters 110a, 110b, 110c, 110d, 110e, 110f, 110g, and 110h are identical in this example embodiment, the plate supporter 110a is used as a primary example to describe these example plate supporters of the present disclosure. The other plate supporters 110b to 110h are not described in detail herein for brevity.

The first leg 114a includes a plate edge holding hand 115a positioned on the deck 60 and connected to the deck 60, and two connected leg members 116a and 117a connected to extending upwardly from the plate edge holding hand 115a. Similarly, the second leg 124a includes a plate edge holding hand 125a (labeled for ease of reference but not shown) positioned on the deck 60 and connected to the deck 60, and two connected leg members 126a and 127a connected to and extending upwardly from the plate edge holding hand 125a. The second leg 124a is aligned with and spaced apart from the first leg 114a. The space between the first and second legs 114a and 124a allows the plate holder pivot actuator 180a to move between the first and second legs 114a and 124a when the jackscrew 190a is actuated to pivot the plate holder 150a as discussed below.
The first pivot pin supporter 130a includes a body that defines a pivot pin receipt opening 132a configured to receive the pivot pin PP1a such that the pivot pin PP1a is supported by the first pivot pin supporter 130a and the first leg 114a. The first pivot pin supporter 130a is connected to the top of the first leg 114a, and specifically to the tops of the two connected leg members 116a and 117a of the first leg 114a. Likewise, the second pivot pin supporter 140a includes a body that defines a pivot pin receipt opening 142a (labeled for ease of reference but not shown) configured to receive the pivot pin PP1a such that the pivot pin PP1a is supported by the first pivot pin supporter 140a and the second leg 124a. The second first pivot pin supporter 140a is connected to the top of the second leg 124a, and specifically to the tops of the two connected leg members 126a and 127a of the second leg 124a. The first pivot pin supporter 130a, the pivot pin PP1a, and the second pivot pin supporter 140a (along with the first (central) pivot bracket 158a as described below), thus form a joint for pivotally supporting the plate holder 150a.
The plate holder 150a includes an elongated top arm 152a having an elongated upper flat surface, a plate edge holding hand 154a at one end of the top arm 152a, a brace 156a connected to and extending downwardly from the bottom surface of the top arm 152a; a first (central) pivot bracket 158a; a second (central) pivot bracket 160a (labeled for ease of reference but not shown); a third pivot bracket 162a; and a fourth pivot bracket 164a (labeled for ease of reference but not shown). The elongated top arm 152a is configured such that part of the steel plate 25 can be positioned on the upper flat surface of the top arm 152a and the plate edge holding hand 154a is configured to be engaged by and support a side edge of the steel plate 25 as best shown in
The first (central) pivot bracket 158a includes a pivot pin receiving bearing 159a and the second (central) pivot bracket 160a includes a pivot pin receiving bearing 161a (labeled for ease of reference but not shown). It should be appreciated that the pivot pin PP1a extends from the first pivot pin supporter 130a through the pivot pin receiving bearing 159a of the first (central) pivot bracket 158a, through an opening (not shown) in the brace 156a, through the pivot pin receiving bearing 161a of the second (central) pivot bracket 158a, and into the pivot pin receipt opening 142a of the second pivot pin supporter 140a to provide a pivotable connection between the plate holder 150a and the first and second legs 114a and 124a. This arrangement enables the plate holder 150a to pivot between the loading position shown in
The plate holder pivot actuator 180a includes a first linkage 181a and a second linkage 184a. The first linkage 181a includes a first pivot member receiver 182a at its top end and a second pivot member receiver 183a at its bottom end. Similarly, the second linkage 184a includes a first pivot member receiver 185a (labeled for ease of reference but not shown) at its top end and a second pivot member receiver 186a at its bottom end. The plate holder pivot actuator 180a is pivotally connected at its top end to the plate holder 150a by the second pivot pin PP2a (labeled for ease of reference but not shown) that is connected to the first pivot member receiver 182a of the first linkage 181a, extends through the third pivot bracket 162a, extends through the brace 156a, extends through the fourth pivot bracket 162a, and is connected to the first pivot member receiver 185a of the second linkage 184a. The plate holder pivot actuator 180a is pivotally connected at its bottom end to the jackscrew 190a by a third pivot pin PP3a (labeled for ease of reference but not shown) that is connected to the second pivot member receiver 183a of the first linkage 181a, extends through a pivot member receiver 191a of the jackscrew 190a, and that is connected to the second pivot member receiver 186a of the second linkage 184a. Various of these components thus form a second joint for pivotally supporting the plate holder 150a. Various of these components also form a third joint for pivotally supporting the plate holder 150a and for transferring the weight of the plate 25 to the follower 196a (described below) and to the deck 60.

When the drive assembly 300 provides a rotational force in a first rotational direction via the right angle gearbox 340a (as discussed below) to the drive coupler 198a, the drive coupler 198a causes the rotation of the threaded rod 192a in that first rotational direction. The rotation of the threaded rod 192a in the first rotational direction causes the follower 196a to move on the threaded rod 192a from a transit position adjacent to the drive coupler 198a (shown in
Likewise, when the drive assembly 300 provides a rotational force in a second rotational direction (opposite the first rotational direction) via the right angle gearbox 340a (as discussed below) to the drive coupler 198a, the drive coupler 198a causes the rotation of the threaded rod 192a in that second rotational direction. The rotation of the threaded rod 192a in the second rotational direction causes the follower 196a to move on the threaded rod 192a from the load position adjacent to the free end of the threaded rod 192a (shown in
It should be appreciated that the jackscrew 190a also functions as a stopping or braking mechanism for the plate holder 150a. Specifically, when the rod 192a of the jackscrew 190a is stationary, the follower 196a is held stationary by the rod 192a, the plate holder pivot actuator 180a is held stationary by the follower 196a, and the plate holder 150a is held stationary by the plate holder actuator 180a. Thus, in each of the loading/unloading and transit positions (and each position therebetween), the jackscrew 190a functions as a stopping or braking mechanism (as long as the rod 192a thereof is not rotating). In other words, the rods are configured not to rotate under normal forces except for intended rotational forces applied to the rods. In addition, the center of gravity of the large steel plate 25 is located laterally within approximately 12 inches of the centerline of the railcar 20 so that the motion of the drive assembly 300 is biased to rotate to the transit position such that the load on the drive assembly 300 is negligible. In alternative embodiments, one or more additional locking mechanisms (not shown) can be employed to releasably secure the plate holders in desired positions such as in the transit or in the loading/unloading positions.
As best shown in
The drive actuator connectors are positioned, oriented, sized, shaped, and otherwise configured to each be releasably connected to a powered external drive actuator (not shown). The powered external drive actuator is thus releasably connectable to the drive assembly 300 via either drive actuator connector at either end of the railroad car 20. This enables a loader to operate the drive assembly 300 of the railroad car 20 from either end of the railroad car 20. It should be appreciated that when an operator is at either end of the railroad car 20, the operator does not need to be below any plates 25 held by the railroad car 20. The present disclosure contemplates that one or more powered external drive actuators will be located at each of the steel plate loading locations and the steel plate unloading locations. The present disclosure thus contemplates that, in various embodiments, the large plate tilt railroad car 20 does not need to include the drive actuators as part of such railroad car. This reduces the complexity, weight, and expense of the railroad car, and also reduces the maintenance associated with such drive actuators. This also enables the various embodiments of the railroad car of the present disclosure to be manufactured without any power source for the plate supporters 110a, 110b, 110c, 110d, 110e, 110f, 110g, and 110h.
A first group of the plurality of first drive shafts are connected to a first one of the drive actuator connectors at a first end of railroad car 20 and a second group of the plurality of drives shafts are connected to the second of the drive actuator connectors at a second end of the railroad car 20 such that the rotational forces provided by a drive shaft (not shown) of the powered external drive actuator (not shown) to either of the drive actuator connectors at either end of the railroad car 20 is transferred from that drive actuator connector through the respective set of first drive shafts to the gear reducer 330 The gear reducer 330 reduces the rotational force provided by the drive powered external drive actuator via the respective drive actuator connector and the respective group of first drive shafts, and transfers that reduced rotational force to the second drive shafts. The gear reducer 330 can be centrally positioned of railroad car 20 to provide more uniform torque distribution for the drive system. The second drive shafts respectively simultaneously transfer such reduced rotational force to the plurality of right angle gearboxes 340a, 340b, 340c, 340d, 340e, 340f, 340g, and 340h that in turn simultaneously transfer those reduced forces to the drive couplers 198a, 198b, 198c, 198d, 198e, 198f, 198g, and 198h of the jackscrews 190a, 190b, 190c, 190d, 190e, 190f, 190g, and 190h. Thus, it should be appreciated that the various pivot jackscrews and the drive assembly function as a plate supporter tilt drive system (for the plate supporter).

In various embodiments, the present disclosure contemplates the following method for operating the railroad car 20 to load one or more large plates (such as steel plate 25) on the railroad car 20: (a) moving the railroad car 20 to a position at a loading area where one or more large steel plates can be loaded by a crane onto the railroad car 20 (such as at a loading area of a manufacturing facility of the large steel plates); (b) connecting a powered external drive actuator to one of the drive actuator connectors of the drive assembly 300 of the railroad car 20; (c) activating the powered external drive actuator to cause the plate holders 150a to 150h of the plate supporters 110a to 110h to pivot to their respective loading positions (shown in
In this example embodiment, step (c) includes activating the powered external drive actuator to cause the powered external drive actuator to provide rotational force in a first direction to the respective drive actuator connector of the drive assembly 300 such that the drive assembly 300 simultaneously transfers that rotational force to the jackscrews 190a to 190h to cause the threaded rods of the jackscrews 190a to 190h to simultaneously rotate to cause the followers of the jackscrews 190a to 190h to transversely move toward the respective second ends of the rods. The transverse movements of the followers of the jackscrews cause the pivot member receivers connected to the followers to simultaneously transversely move and the plate holder pivot actuators (that each include the respective linkages thereof) to simultaneously pivot upwardly to cause the plate holders 150a to 150h to simultaneously pivot upwardly from the downwardly angled transit positions (shown in
In this example embodiment, step (e) includes activating the external drive actuator to cause the external drive actuator to provide rotational force in a second direction (that is opposite the first direction)) to the respective drive actuator connector of the drive assembly 300 such that the drive assembly 300 simultaneously transfers that rotational force to the jackscrews 190a to 190h to cause the threaded rods of the jackscrews 190a to 190h to simultaneously rotate to cause the followers of the jackscrews 190a to 190h to transversely move toward the respective first ends of the rods of the jackscrews. The transverse movements of the followers cause the pivot member receivers connected to the followers to simultaneously transversely move and the plate holder pivot actuators (that each include the respective linkages thereof) to simultaneously pivot downwardly to cause the plate holders 150a to 150h to simultaneously pivot downwardly from the loading positions (shown in
In this embodiment, the present disclosure contemplates the following method for operating the railroad car 20 to unload one or more large steel plates from the railroad car 20: (a) moving the railroad car 20 with the one or more large steel plates held by the plate holders 150a to 150h of the plate supporters 110a to 110h in their respective transit positions to an unloading area to be unloaded by a crane from the railroad car 20 (such as at an unloading area of a manufacturing facility that will use the large steel plates for manufacturing purposes); (b) connecting a powered external drive actuator to one of the drive actuator connectors of the drive assembly 300 of the railroad car 20; (c) activating the powered external drive actuator to cause the plate holders 150a to 150h of the plate supporters 110a to 110h to pivot with the steel plate(s) to their respective unloading positions (shown in
In this embodiment, step (j) is similar to step (c) explained above and is thus not explained again for brevity. In this embodiment, step (I) is similar to step (e) explained above and is thus not explained again for brevity.
It should be appreciated that the present disclosure contemplates that the powered exterior drive actuators that are connected to the drive assembly 300 and used to actuate the drive assembly 300 will be located at the steel plate loading locations and at the steel plate unloading locations, and thus do not need to be part of the railroad car 20.
It should also be appreciated that the present disclosure contemplates that the powered drive actuator(s) that is/are connected to the drive assembly 300 and used to actuate the drive assembly 300 can alternatively be part of the railroad car 20. In certain such embodiments, the powered drive actuator(s) is/are can be powered by an external power source connectable to the drive actuator. In other such embodiments, the drive actuator(s) is/are powered by a power source connected to the drive actuator and on the railroad car 20.
The various components of the plate support assembly 100 and of the drive assembly 300 are made of steel in this example embodiment. It should be appreciated that one or more of such components can be alternatively shaped, sized, configured, and made of different materials in accordance with the present disclosure.
It should be appreciated that the plate support assembly 100 and of the drive assembly 300 of the present disclosure provides a stable support for the steel plates 25. In particular, the jackscrews and the plate holder pivot actuators (that are connected to each other and respectively connected to the drive assembly and the plate holders) are configured to hold the plate holders and any steel plates thereon) in secure stationary positions unless the rods of the jackscrews are rotated (as explained above).

These plate movement blockers 4400a and 4400b can be provided in addition to or instead of the plate movement blockers 400a and 400b that are connected to the deck of the railroad car at the opposite ends of the railroad car as described above. These plate movement blockers 4400a and 4400b are positioned, sized, shaped, otherwise configured to prevent a plate (such as the steel plate 25 described above) that is being transported by the railroad car 4020 from longitudinally moving or substantially moving on the railroad car 4020 when the plate 25 is in the loading or transit positions.
Generally, the illustrated example railroad car 4020 includes plate movement blockers 4400a and 4400b) at respective ends of the railroad car 4020. The plate movement blockers 4400a and 4400b respective include bulkheads 4530a and 4530b configured to limit the longitudinal movements of the plate. The plate movement blockers 4400a and 4400b respectively include moveable gates 4540a and 4540b configured to prevent transverse movements of the plate. In various such embodiments, each such plate movement blocker also includes one or more load transfer assemblies configured to transfer forces incurred by the bulkhead thereof to the deck 4060 of the railroad car 4020.
More specifically, the illustrated example plate movement blocker 4400a includes: (1) a first plate blocker 4500a; (2) an anchor 4600a; (3) a first (or upper) load transfer assembly 4700; (4) a second (or lower) load transfer assembly 4800; and (5) a third load transfer assembly 4900.

The first bulkhead 4530a is configured to be engaged by an end of the steel plate (not shown) and is thus configured to prevent longitudinal movement or substantial longitudinal movement of the steel plate. The gate 4540a is configured to pivot about the hinge assembly 4550a from a closed position (as shown in
The anchor 4600a is connected to the second plate holder 4150b of the second plate supporter 4100b of the plate support assembly (not labeled) of the railroad car 4020. In this example embodiment, the second plate holder 4150b includes an upper extension member 4160b that is moveable to different heights as shown in
The first load transfer assembly 4700 includes a load transfer frame 4710 having a first end connector plate 4720 connecting a first end of the frame 4710 to the first load plate holder 4150a and a second end connector plate 4730 connecting a second end of the frame 4710a to the second plate holder 4150b. The frame 4710 includes an upper member 4750, a lower member 4770, and a plurality of cross members 4760 connected to and connecting the upper member 4750 and the lower member 4770. The frame 4710 can be otherwise suitably positioned, shaped, sized, and otherwise configured in accordance with the present disclosure.
Likewise, the second load transfer assembly 4800 includes a load transfer frame 4810 having a first end connector plate 4820 connecting a first end of the frame 4810 to the first load plate holder 4150a and a second end connector plate 4830 connecting a second end of the frame 4810 to the second plate holder 4150b. The frame 4810 includes an upper member 4850, a lower member 4870, and a plurality of cross members 4860 connected to and connecting the upper member 4850 and the lower member 4870. The frame 4810 can be otherwise suitably positioned, shaped, sized, and otherwise configured in accordance with the present disclosure.
The first and second load transfer assemblies 4700 and 4800 are configured to co-act to transfer forces incurred by the steel plate 25 engaging the plate blocker 4500a (and particularly the bulkhead 4530a) to the anchor 4600a.
The anchor 4600a is configured to transfer these forces received from the first and second load transfer assemblies 4700 and 4800 to the third load transfer assembly 4900.
In this illustrated example embodiment, the third load transfer assembly 4900 has a somewhat tent like or A-frame like structure although the structure can vary in accordance with the present disclosure.
More specifically, the third load transfer assembly 4900 includes a head 4910, a first leg 4930, a second leg 4950, and a leg connector 4400. The head 4910 is connected to an upper end of the first leg 4930 and to an upper end of the second leg 4950.
The head 4910 includes a cylindrical tube in this example embodiment, but can be otherwise suitably formed. The head 4910 is connected at a first end to the first plate supporter 4100a and at a second end to the second plate supporter 4100b.
The first leg 4930 is connected to the head 4910 and extends downwardly from the head 4910 to the deck 4060, and is fixedly connected to the deck 4060. The first leg 4930 is in the form of a plate in this example embodiment, but can be otherwise suitably configured. The first leg 4930 is suitably configured to transfer forces from the anchor 4600a to the deck 4060.
The second leg 4950 is connected to the head 4910 and extends downwardly to from the head 4910 to the deck 4060, and is fixedly connected to the deck 4060. The second leg 4950 is also in the form of a plate in this example embodiment, but can be otherwise suitably configured. The second leg 4950 is suitably configured to transfer forces from the anchor 4600a to the deck 4060.
The leg connector 4940 is fixedly connected to the first and second legs 4930 and 4950, extends between the first and second legs 4930 and 4950, extends downwardly to the deck 4060, and is fixedly connected to the deck 4060. The leg 4950 is also suitably configured to transfer forces from the anchor 4600a to the deck 4060.
The third load transfer assembly 4900 is thus configured to transfer forces from the anchor 4600a to the deck 4060.
It should be appreciated from the above, that in various embodiments the present disclosure provide a railroad car that can transport large plates without pneumatically powered or hydraulically powered plate movement systems.
It will be understood that modifications and variations may be affected without departing from the scope of the novel concepts of the present invention, and it is understood that this application is to be limited only by the scope of the claims.
