The utility model provides a movable top cover system for a railway open wagon, which can open the top cover when loading and unloading goods, and is convenient for loading and unloading goods; the top cover is closed in the transportation or other periods when the goods are not required to be loaded and unloaded, so that the pollution caused by the scattering of the goods is prevented.

Referring to fig. 1 to 5 and 8, the present invention provides a movable cover system, which includes a mounting frame 800, a cover unit 100, a sliding rail 200, and a cover-pulling device 300:

the mounting bracket 800 includes a mounting plate and a leg 810, one end of the leg 810 is fixedly mounted on the side wall 910 and the end wall 920, and the side plate is fixedly mounted on the other end of the leg 810. The size of the side panels can be adjusted according to different types of railway open wagons, and are fixedly connected to the cargo box 900 by a plurality of support legs 810, and serve as a mounting base for the roof units in the movable roof system. The top cover unit 100 can be unfolded or folded and has a corresponding unfolded state and a corresponding folded state, and when the top cover unit 100 is in the unfolded state, the top of the open wagon container 900 can be closed; when the roof unit 100 is in the folded state, it can be retracted to the end of the cargo compartment 900 in the longitudinal direction, so that the cargo compartment 900 is open at the top. One end of the top cover unit 100 is provided with an end beam 130, and the end beam 130 is provided with a stopper mechanism.

The sliding rail 200 is arranged on the mounting rack 800 and comprises a first rail 210, and the first rail 210 is arranged on the top of the mounting rack 800 along the horizontal direction; the open wagon cargo compartment 900 comprises side walls 910 and end walls 920, the sliding rails 200 are arranged on the side walls 910 at two sides of the cargo compartment 900 along the length direction in pairs, and the top cover unit 100 can slide in the sliding rails 200, so that the whole top cover unit 100 can be unfolded and folded.

The cover-pulling device 300 is disposed on the ground, and when the railway open wagon operates, the cover-pulling device 300 can block the movement of the stopping mechanism, so that the stopping mechanism drives the top cover unit 100 and the container 900 to move relatively, and the top cover unit 100 is unfolded and folded.

The movable top cover system formed by the top cover unit 100, the sliding rail 200 and the cover shifting device 300 can utilize the kinetic energy of the railway open wagon to open and close the top cover when the railway open wagon needs to load and unload goods, has a simple structure, is convenient to operate, and can effectively reduce the loss and the pollution to the environment caused by the open top when the open wagon transports goods.

Preferably, the top cover unit 100 includes a plurality of shutters 120 and a plurality of connection shafts 110. A plurality of shutters 120 are used to cover the open top of the cargo bed. The plurality of connecting shafts 110 are parallel to each other and slidably disposed at the top opening of the cargo box, and the plurality of connecting shafts 110 have a first state where they are spaced apart by a predetermined distance in pairs and a second state where they are abutted against each other in pairs. Both sides of each of the shielding members 120 are respectively connected to two adjacent connecting shafts 110, and when the plurality of connecting shafts 110 are in the first state, the plurality of shielding members 120 cover the top opening of the cargo compartment 900. The shutter 120 includes first and second cover panels hinged together by a hinge structure and having a relatively unfolded state and a relatively folded state. One side of the first cover plate, which is far away from the second cover plate, is hinged with one connecting shaft 110, one side of the second cover plate, which is far away from the first cover plate, is hinged with the adjacent connecting shaft 110, and when the plurality of connecting shafts 110 are in the first state, the first cover plate and the second cover plate are in a relatively unfolded state. When the plurality of connection shafts 110 are in the second state where two of them are oppositely abutted, the first cover panel and the second cover panel are oppositely folded, so that the top of the cargo box 900 is opened. Moreover, the sliding mechanisms 140 are disposed at two ends of the connecting shaft 110, and the sliding mechanisms 140 are disposed in the sliding rails 200, so that the connecting shaft 110 can slide along the sliding rails 200, and further the top cover unit 100 is driven to unfold or fold. Preferably, the length of the first rail 210 is greater than that of the side walls 910, and when the roof unit 100 is in the contracted state, the roof unit can be completely contracted to a protruding section of the first rail 210 protruding from the top of the container 900 of the gondola, so that the top of the container 900 is completely opened.

Preferably, referring to fig. 2 and 4, the sliding rail further includes a second rail 220 and a third rail 230. The first rail 210 is horizontally arranged at the top of the mounting frame 800, the second rail 220 is vertically arranged at the side of the mounting frame 800, and the third rail 230 is connected with the first rail 210 and the second rail 220; the second rail 220 and the third rail 230 can be regarded as the protruding section of the first rail 210 protruding from the truck container 900 and bent downward. When the roof unit 100 is in the folded state, it can be fully collapsed within the second rail 220 or the second and third rails 220, 230 such that the top of the cargo box 900 is fully open. Since the top cover unit 100 has a certain thickness even after being contracted, the sliding rail 200 accommodating the top cover unit 100 in the folded state should have a certain length. The second rail 220 in the vertical direction is arranged, so that the protruding section of the first rail 210 protruding out of the container 900 can be prevented from being too long, and the distance between two adjacent containers 900 is shortened and even interfered.

The above-mentioned shrinking of the top cover unit 100 to the protruding section of the first rail 210 protruding from the gondola container 900 or the shrinking of the top cover unit 100 into the second rails 220 disposed at both sides of the container 900 in the extension direction is to fully open the top of the container 900. For a railway truck, particularly a truck for transporting bulk materials such as coal, stone, etc., the cargo box 900 of the truck is usually turned 180 ° by a tippler to dump the bulk materials out of the cargo box 900 when unloading. If the top of the cargo box 900 cannot be completely opened after the top cover unit 100 is retracted, the rate of dumping the cargo may be affected, and the cargo may impact the top cover unit 100 when dumped, which may cause damage to the top cover unit 100.

Preferably, referring to fig. 1 and 2, the number of the roof units 100 is two, the roof unit 100 includes a first roof and a second roof, and the two roof units 100 are oppositely disposed at two sides of the cargo box 900 to form a side-by-side structure. Correspondingly, the second rail 220 of the cargo box 900 also has two sections, which are disposed at two ends of the cargo box 900 of the gondola along the length direction. Meanwhile, a linkage mechanism 400 is arranged between the two cover units 100, and the linkage mechanism 400 can enable the two cover units 100 to move in a relevant manner and always open or close at the same time.

In some embodiments, the stopper mechanism is provided only on one of the cover units 100 of the split movable covers provided with the linkage mechanism 400, and the stopper mechanism provided on the first cover will be described as an example. When the open top vehicle is operated, the top cover unit 100 is in a closed state, and the end provided with the second top cover first passes through the cover-pulling device 300, and since the second top cover is not provided with the stop mechanism, the front half part of the cargo box 900 does not collide with the cover-pulling device 300. When the rear half part of the container 900, that is, the part enclosed by the first top cover passes through the cover-pulling device 300, the cover-pulling device 300 collides with a stop mechanism on the movable end of the first top cover, so as to drive the first top cover to fold and move relative to the container 900; meanwhile, the first top cover drives the second top cover to move through the linkage mechanism 400, and the two top covers have the same movement speed and opposite directions. When the first top cover is completely folded and contracted, the second top cover is also completely folded and contracted synchronously, so that the top of the container 900 is completely opened. At this time, the first top cover is used as a driving part to drive the second top cover as a driven part to move. However, it should be noted that, in the active and passive matching type split movable top cover, when the top cover is to be closed, the open wagon needs to turn around, that is, when the top cover is closed, the end provided with the first top cover first passes through the cover-pulling device 300, so that the closing action of the top cover can be normally completed.

In other embodiments, for a split movable top cover with the linkage 400, the two top cover units 100 are provided with stop mechanisms, and the stop mechanisms on the two top cover units 100 are arranged in a staggered manner. For example, when the open wagon is driven from south to north, the first top cover is located at the end of the cargo box 900 near the north, i.e. when the open wagon passes through the cover-pulling device 300, the first top cover first passes through the cover-pulling device 300, the stop mechanism on the first top cover is arranged at the west side of the open wagon, and the stop mechanism on the second top cover is arranged at the east side of the open wagon. When the open wagon enters the unloading place to unload, the top cover unit 100 is in a closed state, the open wagon first passes through the cover opening lid-lifting device 300 arranged at the south of the unloading place, and the cover opening lid-lifting device 300 is arranged at the east side of the railway track. When the open wagon passes through, the cover opening device 300 for opening the east side cannot collide with the stop mechanism on the west side of the first top cover, only collides with the stop mechanism on the east side of the second top cover, drives the second top cover to be folded, and meanwhile, the second top cover drives the first top cover to be folded through the linkage mechanism 400, so that the opening of the top cover unit 100 is completed. And after the open wagon is unloaded, the open wagon continues to run from south to north, passes through the cover closing cover shifting mechanism at the north part of the unloading place, and is arranged at the west side of the railway track. When the open wagon passes through, the cover-closing cover-shifting device 300 positioned on the west side cannot collide with the stop mechanism positioned on the east side on the second top cover, and only collides with the stop mechanism positioned on the west side on the first top cover, and drives the first top cover to expand, and meanwhile, the first top cover drives the second top cover to expand through the linkage mechanism 400, so that the top cover unit 100 is closed.

Preferably, referring to fig. 2, the linkage mechanism 400 includes two transmission wheels 410, two ring-shaped transmission members 420 and end beams 130, wherein the two transmission wheels 410 are disposed at two ends of the container 900 along the length direction; the annular transmission members 420 are disposed on the two transmission wheels 410 and can rotate around the transmission wheels 410, the upper half part of the annular transmission members 420 is an upper side transmission member, the lower half part of the annular transmission members 420 is a lower side transmission member, and the end beams 130 of the two top cover units 100 are respectively and fixedly connected to the upper side transmission member and the lower side transmission member. For example, when the first top cover is folded to open the top cover unit 100, the first top cover end beam 130 moves to the left to drive the upper transmission member to move to the left, so that the annular transmission member 420 rotates counterclockwise. At the same time, the lower transmission member moves to the right and drives the second top cover end beam 130 to move to the right, so that the second top cover is folded.

Preferably, as shown in fig. 5, the linkage 400 includes a sprocket and a chain, only a portion of which is shown. The sliding mechanisms 140 at the upper end beams of the first top cover and the second top cover are respectively and fixedly connected with the chains through the long connecting plates and the short connecting plates, meanwhile, chain supporting plates are further arranged on the mounting frame in order to prevent the chains from sagging due to self weight, and the chains penetrate through the slots in the chain supporting plates. The working principle of the chain wheel and chain for controlling the top cover unit to be synchronously opened is the same as that of the driving wheel and the driving part, and the description is omitted.

It should be understood that the sprocket and chain engagement, the sheave and wire rope engagement, and the like are but some of the possible ways, and other common synchronous drives, such as pulleys and belts, may be used in the present invention.

Preferably, for a split movable top cover provided with the linkage 400, the linkage 400 is further connected with a driving mechanism, and the driving mechanism can actively drive the linkage 400, so that the linkage 400 drives the top cover unit 100 to complete opening or closing. For example, for the top cover unit 100 provided with the driving wheel 410 and the annular transmission member 420, the driving mechanism is a motor, the motor is directly connected to the driving wheel 410 or connected to the driving wheel 410 through a speed reducing mechanism, and can drive the driving wheel 410 to rotate, the annular transmission member 420 is tensioned on the driving wheel 410, and the driving wheel 410 rotates to drive the annular transmission member 420 to rotate, thereby driving the top cover unit 100 to move. For another example, for a movable roof system having a chain and sprockets as the linkage 400, the arrangement of the chain sprockets and the connection to the roof unit 100 are similar to the arrangement of the drive wheels 410 and the transmission members described above. The motor is arranged and can be connected to the chain wheel, the driving chain wheel drives the chain to rotate, or the motor is connected to the chain and directly drives the chain to rotate. It should be understood that the above two forms are just some possible embodiments of the driving mechanism and the linkage mechanism 400, and that other common driving mechanisms and linkage mechanisms 400 in the mechanical field may also be applied to the movable roof system provided by the present invention.

Preferably, referring to fig. 7, the linkage mechanism 400 is provided with an adjusting mechanism 430. As shown in fig. 7, the adjusting mechanism 430 includes a bolt, and the driving wheels 410 are mounted on the top cover unit 100 through the adjusting mechanism 430, and by adjusting the bolt, the distance between the two driving wheels 410 can be adjusted, thereby adjusting the tension of the endless drive member 420. It should be understood that the bolt is only one type of means that can be used in the present invention, and other common tension adjusting mechanisms can also be used in the present invention.

Preferably, referring to fig. 6, the sliding rail 200 further includes a limiting member 240, and for the sliding rail 200 having only the first rail 210, the limiting member 240 is disposed at the ends of the two ends of the first rail 210. For the sliding rail 200 including the second rail 220 and the third rail 230, the stopper 240 is disposed at the lower end of the second rail 220 in the vertical direction. The sliding mechanism 140 of the top cover unit 100 is slidably disposed in the sliding rail 200, and in order to prevent the sliding mechanism 140 from coming out of the sliding rail 200 when the top cover unit 100 is retracted, a stopper 240 is disposed at the end of the second rail 220. When the top cover unit 100 is retracted, the sliding mechanism 140 closest to the stopper 240 contacts the stopper 240 and does not move any more, so that the sliding mechanism 140 does not fall off the sliding rail 200.

Preferably, the number of the cap unit 100 is one. For a container 900 with one header unit 100, the header unit 100 can be deployed to completely cover the top of the container 900 and collapsed to one side of the top of the container 900 to fully open the top of the container 900. When the top of the open wagon is opened, the open wagon is in a certain direction, the stop mechanism at the movable end of the top cover unit 100 is stopped by the cover pulling device 300, the top cover unit 100 is driven to be folded, the folding of the top cover unit 100 is completed, and the process of closing the top of the open wagon is opposite to the opening process. Only one cover unit 100 is provided, the link mechanism 400 is not required, the structure of the movable cover system is simplified, and the reliability of the movable cover system is improved. It should be noted that when the top of the open wagon is opened or closed, the end of the open wagon where the stopping mechanism is located should first pass through the cover-lifting device 300, so that the cover-lifting device 300 can open or close the top cover unit 100.

Preferably, referring to fig. 1, the number of the cover-pulling devices 300 is 2, and 2 cover-pulling devices 300 are oppositely arranged on two sides of the railway track. Accordingly, there are also 2 stopper mechanisms, corresponding to 2 cover lifting devices 300 when the top cover unit 100 is opened or closed. Since the top cover unit 100 is limited by weight and structure, the amount of force that can be provided by the stopper mechanism is limited, and the provision of only one set of the stopper mechanism and the cover-lifting device 300 may result in insufficient opening or closing force; meanwhile, since the cover-moving devices 300 are disposed on both sides of the railway, when one cover-moving device 300 is disposed, only an acting force is applied to the stopping mechanism on one side of the cover unit 100, which may cause the sliding of the two sliding rails 200 of the movable cover system to be mismatched, resulting in a jamming phenomenon. Two cover-pulling devices are arranged, on one hand, acting force on the top cover unit 100 can be increased, on the other hand, force can be simultaneously applied from two sides of the top cover unit 100, and the situation that the two sliding rails 200 are not matched in movement is avoided.

Preferably, the material of the shielding member 120 in the top cover unit 100 is a rigid material. The rigid shield 120 is rectangular in shape, has a length equal to the width of the top of the cargo bed 900, and has a thickness that can be determined according to specific requirements, and generally has a thickness in the range of 1mm to 20 mm. The rigid shield 120 can cover the top of the cargo box 900 when the top cover unit 100 is opened, preventing foreign objects from entering the cargo box 900 or cargo in the cargo box 900 from falling out. Meanwhile, the rigid shielding member 120 can also play a certain connecting role, so that the sliding mechanisms 140 at the two ends of the connecting shaft 110 can move synchronously. Further, in order to avoid a gap between two adjacent rigid shielding members 120, a flexible material such as tarpaulin may be filled in the gap between two rigid shielding members 120, so as to prevent cargo from falling or impurities from entering due to the gap between the rigid shielding members 120 without affecting the normal extension and retraction of the cover unit 100.

Preferably, the movable roof system further comprises a locking mechanism. The locking mechanism is disposed on the top cover unit 100, and when the top cover unit 100 is unfolded to seal the top of the cargo compartment 900, the locking mechanism can lock the top cover unit 100, so that the top cover unit 100 is unfolded and cannot be folded, and the cargo compartment 900 is kept sealed. For example, for a split type movable top cover, the locking device includes a lock body and a lock tongue respectively disposed on two top cover units 100, when the two top cover units 100 are unfolded, the lock body and the lock tongue are close to each other, when the top cover units 100 are completely unfolded, the lock tongue is inserted into the lock body, and when a force exceeding a certain magnitude is not applied, the lock tongue and the lock body maintain a locked state, so that the two top cover units 100 cannot be folded. The locking mechanism can prevent the top cover unit 100 from being opened accidentally because the top cover unit 100 is opened accidentally due to self-shaking of the open wagon during running or force applied to the top cover unit 100 by some other accidental factors during running of the open wagon.
