摘要： Disclosed is a railway hopper car comprising a car body (6), a top cover (1, 2), a bogie (24), a braking device (21), a coupler buffer device (22), and a bottom door (25, 28) and a bottom door opening and closing mechanism (23) mounted at a discharge port at the bottom of a chassis. The railway hopper car further comprises a longitudinal saddle (31) disposed in the center of the car body (6) in the length direction thereof and arranged along the longitudinal direction of the car body (6). By providing the longitudinal saddle (31), the sequential requirement to close the left bottom door (25) and the right bottom door (28) is eliminated, thereby simplifying the structure of the linkage bottom door opening and closing mechanism and reducing manufacture and maintenance costs thereof.

摘要： According to some embodiments, a railcar comprises: an underframe comprising a center sill extending longitudinally along a centerline of the railcar; a hopper coupled to the underframe and comprising a discharge opening; and a discharge assembly coupled to the hopper. The discharge assembly comprises: a sloped side sheet, and a discharge gate frame in a plane offset from horizontal and extending from a bottom of the sloped side sheet to proximate the center sill. The discharge gate frame at least partially surrounds the discharge opening. The discharge assembly further comprises a discharge gate coupled to the discharge gate frame. The discharge gate is operable to move from a closed position that restricts a lading from discharging to an open position that permits the lading to discharge. Moving from the closed position to the open position comprises moving at an angle upward and transverse to the railcar.

摘要： A railcar ballast delivery gate with first and second parallel side walls spaced apart by a center truss plate that extends between and is perpendicular to each of the two side walls, a center angled bar that straddles the center truss plate, first and second primary elongated tubes extending between the first and second side walls on opposing sides of the side walls, and a divider assembly. The primary elongated tubes are rotatably connected to first and second tube arms, which in turn are fixedly couple to first and second secondary elongated tubes that are configured to move relative to the primary elongated tubes while remaining parallel to them. The tube arms are rotatably connected to door linkages that are situated underneath and fixedly attached to door panels resting on trusses that extend from a center truss plate.

摘要： A mechanism for operating a discharge gate assembly mounted on a railcar. The gate assembly includes a frame defining a discharge opening, a door slidably positioned on the frame for a generally horizontal range of movements between a closed position and an open position. An operating shaft assembly is mounted on the frame for rotation about a fixed axis and is operably coupled to the door such that the door moves in response to rotation of the operating shaft assembly. The mechanism for operating the discharge gate assembly includes a mount carried by and with the railcar and an actuator carried by the mount outside a range of travel of the slidable door. A force transfer mechanism is operated by the actuator for rotating the operating shaft assembly to slidably move the door between the closed and open positions in response to operation of the actuator.

摘要： A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by movable closure members. The hopper car has a plurality of hoppers of which two hoppers share a common ridge assembly. The ridge assembly forms a common mating and fit up location for the upper margins of the slope sheets of two lengthwise adjacent hoppers. The ridge assembly includes an horizontal center section and two end plates that angle upwardly outboard toward the top chords of the side walls. The ridge assembly stands proud of the upper margin of the respective adjacent slope sheets. A gusset is mounted between the adjacent slope sheets below the ridge plate such that the slope sheets and gusset form a reinforcement tube running across the car, the end plates forming the stems of a vertical T-section attached to the side wall and overlapping the top chord.

摘要： A method of delivering proppant to a well site has the steps of transporting a load of proppant in a vessel to a desired location, moving the load of proppant from the vessel into a container so as to create a proppant-loaded container, unloading the proppant-loaded container into a pneumatic bulk trailer, and transporting the unloaded proppant in the pneumatic bulk trailer to well site. The container is placed onto a bed of a truck and moved in proximity to the vessel. The proppant-loaded container is placed onto a tilting mechanism and then tilted so that the proppant is discharged through a flow gate of a container into a hopper. The proppant in the hopper can then be conveyed to the pneumatic bulk trailer.

摘要： A hatch cover for a covered hopper railcar includes a substantially circular shell member having a radially outer circumferential perimeter. The substantially circular shell member includes a topside surface and an underside surface. The hatch cover also includes a downwardly extending rim member coupled to and unitarily formed with the substantially circular shell member. The substantially circular shell member and the downwardly extending rim member define a shell/rim interface at the underside surface. The hatch cover further includes at least one sealing gasket fixedly coupled to the underside surface proximate the shell/rim interface.

摘要： A mechanism for operating one or more hinged doors on a hopper car including an elongated operating shaft having a fixed axis of rotation and a linkage system for operably connecting the operating shaft to the hinged doors on the railroad hopper car. The linkage system includes an actuating link operably connected to and rotatable with the operating shaft and a connecting link for operably connecting the actuating link to each door. The linkage system links includes a primary lock for holding each door in the closed position. A selectively operated secondary lock is rotatable about a fixed axis disposed above the fixed axis of the operating shaft assembly. The secondary lock rotates between a first condition, wherein a stop engages with at least one link of the linkage assembly, and a second condition, wherein each door is permitted to move to the open position. A release mechanism is provided for releasing the primary lock by moving at least one of the links of the linkage system relative to the other thereby allowing the door to be forcibly moved toward their open position under the influence of the columnar load being placed thereon by the lading in the hopper.
