The invention discloses a sliding top cover of a railway maneuvering equipment vehicle. The sliding top cover of the railway maneuvering equipment vehicle comprises a fixed cover body and a movable cover body. A lifting mechanism and a sliding mechanism are arranged below the movable cover body and are used for driving the movable cover body to move up and down and move front and back relative tothe fixed cover body. The lifting mechanism comprises a supporting frame. A plurality of lifting machines and a first driving mechanism used for driving the lifting machines to rise and fall are arranged on the lower side of the supporting frame. The sliding mechanism comprises a plurality of gears and a plurality of racks arranged in parallel on the bottom end face of the movable cover body and asecond drive mechanism used for driving the gears to rotate. The racks are arranged in the front-back movement direction of the movable cover body, and the gears are meshed with the corresponding racks. By the adoption of the sliding top cover of the railway maneuvering equipment vehicle, the opening process of the movable cover body can be mainly divided into the two processes of jacking and sliding opening, the mechanical structures of the two processes are independent and do not interfere with each other, and then the complexity of the mechanical structures and transmission mechanisms is lowered.

A railcar having a longitudinal axis and a movable cover. The movable cover includes a plurality of linear bearing devices and at least one slideable hatch connected to the plurality of linear bearing devices. The slideable hatch is movable substantially normal to the longitudinal axis.

The invention relates to an inlet closure system for covering an inlet formed in an upper region of a container body The container body may a storage region of a hopper, a hopper vehicle such as a hopper railway wagon or other storage devices. The inlet closure system comprises at least one closure member arranged substantially above the inlet and moveable between a first closed configuration in which the inlet is substantially closed and a second fully open configuration in which the inlet is substantially open, and at least one actuator mounted on an end wall of the container body for moving the closure member. The actuator remains below an upper edge of the end wall when the closure member is in the second fully open configuration. The actuator is arranged in use to act upon the at least one closure member via a linkage, which linkage is arranged for pivotal motion relative to the end wall about a point substantially midway between the side walls. The linkage may comprise a first link and a second link. The second link may have a first and a second limb which meet at a non-straight angle. Preferably, the first limb and / or the second link lie below the upper edge of the end wall when the closure member is in the second fully open configuration. The second limb may lie substantially beyond an inward facing surface of the closure member when the closure member is in the second fully open configuration. If two actuators are arranged to act upon respective closure members, the first links of the linkages are arranged to pivot about a common pivot point. The common pivot point is preferably located on the end wall at a point substantially midway between the sidewalls.

A railcar having a longitudinal axis and a movable cover. The movable cover includes a plurality of linear bearing devices and at least one slideable hatch connected to the plurality of linear bearing devices. The slideable hatch is movable substantially normal to the longitudinal axis.

The invention provides a top cover device and a rail vehicle having the same, the top cover device comprises two cross telescopic frames, wherein the two cross telescopic frames are arranged at intervals. The cross telescopic frames comprise a plurality of connecting rods, each two connecting rods is a group of connecting units, the middle parts of the two connecting rods of each group of connecting units are hinged, and the ends of the connecting rods of the adjacent two groups of connecting units are hinged corresponding to each other. A plurality of shields disposed between the two cross telescopic frames, the two ends of each shield being connected with connecting rods of the two cross telescopic frames, and the plurality of shields being used for shielding the top of the cargo compartment when the cross telescopic frames are in an unfolded state; the driving device is drivingly connected with the cross telescopic rack, and is used for driving the cross telescopic rack to be in anexpanded state or a contracted state, and when the cross telescopic rack is in a contracted state, the driving device can drive the cross telescopic rack to be turned over. The technical proposal provided by the present application can solve the problem that the tarpaulins in the prior art cannot protect the goods.
