摘要:
Sliding wall sections are co-planar in the closed state and are movable out of the closing plane and into a shifting plane by operation of respective hand levers and actuating linkage connected to the hand levers. The wall sections are displaceable longitudinally, to open the sliding walls, on rolls engaging fixed wall parts and intermediate posts of a side wall frame having an upper stringer, a lower outer beam and corner posts. Sealing of the vertical edges of the sliding wall sections to each other and to the corner and intermediate posts of the side wall frame is effected by labyrinth packings. Each actuating linkage is operable to oscillate a respective upper shaft about a longitudinal axis, and each upper shaft has at least two levers extending therefrom and rotatably mounting rollers in their free ends. Brackets are supported on the floor of the container, adjacent the lower outer beam, by parallel linkages for substantially horizontal movement transversely of the container, each bracket including a vertical web plate on its outer end extending longitudinally of the container, and each web plate, in the outer position of each bracket, conformingly fitting in a cutout in a depending leg of the lower outer beam. The respective parallel linkages include levers secured to respective lower shafts oscillatable about a longitudinal axis by the associated actuating linkage. Arms on the upper portion of each wall section support runner rolls rotatable about horizontal axes, and have supporting cams cooperating with the first mentioned rolls. Lower supporting arms on each wall section rotatably support rolls for rotation about vertical axes and have channel-shaped guide clamps embracing the web plate of the associated bracket and operable to embrace the vertical leg of the lower outer beam. Each wall section, when moved into the shifting plane by oscillation of the upper and lower shafts, is displaceable longitudinally by engagement of its runner rolls with a continuous runner rail and by engagement of its lower rolls with the outer surface of the dependent leg of the outer beam. Interengageable metallic seals are provided on the ends of the wall sections, with each seal including a series of sealing sections arranged along the associated vertical end, the sealing sections having bevelled outer sealing surfaces which alternately slant in respective opposite directions. Profile strips at each corner and intermediate post are arranged to rotate about vertical axes and engage the ends of a wall section when the latter is being moved into the closing plane to guide the section obliquely toward the longitudinal center line of the container to effect tight sealing engagement of the sealing surfaces of the section with the mating sealing surfaces of an adjacent wall section already in the closing plane.
摘要:
A movable side wall and opening/closing mechanism for railroad boxcars, comprising a side wall assembly (1), an end-portion opening/closing mechanism (2), a hinged rod assembly (3), a lateral door central clamping device (4), a upper transmission shaft assembly (5), a lower transmission shaft assembly (6), a upper track assembly (7) and a lower track assembly (8); upon loading/unloading cargo, the movable side wall can be opened further, so as to allow multiple forklifts of any tonnage on the ground to load/unload cargo to/from any positions of a carriage; the hinged rod assembly (3) and the central clamping device (4) are provided to keep the movable side wall reliably closed in order to ensure security and self-locking during transportation.
摘要:
A door opening and closing apparatus including a lock mechanism that is configured to hold the door in a fully closed state, and that has an engaging member which engages with a lock member provided in the door when in the fully closed state. A link mechanism having a plurality of link members is configured to be able to undergo deformation into a linear state and a bent state, and restricts rotation of the engaging member by being brought into the linear state. In the link mechanism, a first face is pressed by a projecting shaft moved by the actuator in order that the link mechanism changes from the linear state to the bent state, and a second face is pressed by the projecting shaft in order that the link mechanism changes from the bent state to the linear state.
摘要:
The freight car has an undercarriage and a running carriage connected to the undercarriage. A container is connected to the undercarriage. The container has side walls, positioned in the longitudinal direction of the freight car, and closed end walls extending transversely to the side walls at opposite ends of the freight car. The side walls have lateral posts and longitudinal supports connecting the end walls and the laterals posts. At least one of the side walls has a closable opening for loading and unloading goods to be transported in the freight car. The at least one opening extends over the entire length of the side wall. The at least one side wall has at least one pair of folding doors arranged in a common vertical plane for closing the opening in a closed position of the folding doors. Each one of the folding doors of the pair has a horizontal pivot axis. The horizontal pivot axle of the first one of the folding doors is provided at the undercarriage and the first folding door covers a lower part of the side wall. The horizontal pivot axle of the second one of the folding doors is provided in the vicinity of the longitudinal support and the second folding doors covers an upper part of the side wall.

A railroad car arranged to transport automobiles comprises a floor, a roof, a pair of spaced sidewalls, and at least one door assembly that is guided to a position adjacent a sidewall to enable loading and unloading of the rail car. A rail guides the lower end of the door assembly. The rail is positioned along the floor of the rail car. A plurality of fingers attached to the door assembly and extend to a sliding engagement with the rail. The rail has uninterrupted sections and extends substantially entirely across the floor between the sidewalls and has two spaced depressible sections that are pushed down by the tires of automobiles rolling thereover. Each depressible section comprises a predetermined length of guide rail, springs for biasing said guide rail upwardly, and preferably, a slotted channel through which said guide rail partially extends.

A side wall assembly particularly for freight cars includes an upper longitudinal beam spaced above a lower longitudinal beam which is carried on the undercarriage and with a corner post connected between the beams at each end. A pivot bolt boss is provided on each beam intermediate their length and a middle post is secured in position by horizontally extending bolts which engage in the bores and which are substantially perpendicular to the longitudinal axis of the car. A rubber or plastic seal is provided between the middle post and the upper and lower longitudinal beams or girders. A cover sheet is arranged over the middle and a portion of the upper longitudinal member and it extends over the entire width of the post and is secured thereto such as by securing screws.
摘要:
A vehicle such as a railway car or over-the-highway carrier is provided with a floor and roof construction which defines a cargo space enclosed by a flexible sliding wall of endless configuration. The wall includes an opening which upon the operation of an actuating mechanism is moved to a plurality of longitudinally spaced positions providing access to the cargo space from opposite sides of the vehicle. In one of the positions a solid vertical wall section masks the opening in the wall and the cargo space is fully enclosed. A modified construction includes a pair of flexible wall sections which are moved to open and closed positions by winch mechanisms.
