The cargo railway open wagon is mainly used for transporting bulk cargos such as coal, ore, wood and the like, a top cover is not arranged on the top of a cargo compartment of the cargo railway open wagon for facilitating loading and unloading of the cargos, and the cargo compartment of the railway open wagon generally consists of a side wall with a longer length, an end wall with a shorter length and an underframe. The utility model provides a split type movable top cover for a railway open wagon, which can be opened when goods are loaded and unloaded, and is convenient for loading and unloading the 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.

As shown in fig. 1 to 3, the present invention provides a split type movable top cover and related equipment thereof, including a mounting frame 800, a top 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 compartment 900 by a plurality of 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 cargo compartment 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 number of the roof units 100 is two, the roof unit 100 includes a first roof 101 and a second roof 102, and the two roof units 100 are oppositely disposed at both sides of the cargo compartment 900 to form a side-by-side structure. Accordingly, the second rail 220 of the cargo box 900 has two sections, which are disposed at both ends of the open wagon cargo box 900 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.

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 arranged on the ground, when the railway open wagon runs, 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 cargo compartment 900 to move relatively, and the top cover unit 100 is unfolded and folded.

Preferably, referring to fig. 2 and 3, the stopping mechanism includes a touch arm disposed above the end beam 130 and fixedly connected to the end beam 130. The projection of the touch arm along the length direction of the cargo compartment is not blocked by the projection of the roof unit 100 or other parts of the open wagon along the same direction, in other words, the top end of the touch arm is higher than other parts of the whole open wagon. Correspondingly, the part of the cover-pulling mechanism, which is in contact with the stop mechanism, is also positioned at the upper part of the open wagon, and the top of the touch arm is higher than the other parts, so that the cover-pulling mechanism only collides with the touch arm, and the movable top cover is opened or closed.

Preferably, referring to fig. 2, the touch arms on the two roof units 100 are symmetrically disposed about the geometric center of the top of the cargo compartment. Typically, the cargo bed is rectangular and the geometric center of the top of the cargo bed is the geometric center of the rectangle of the top of the cargo bed. Since the railway open wagon needs to turn around during running in the track, the touch arms on the top cover unit 100 are designed in a central symmetry mode, and the relative positions of the touch arms and the ground cannot be changed before and after the open wagon turns around. For example, a touch arm a is arranged on the first top cover 101, a touch arm B is arranged on the second top cover 102, and the touch arm a and the touch arm B are symmetrically arranged about the geometric center of the top of the cargo compartment; the ground is used as a reference system, after the train is turned around, the touch arm B moves to the position of the touch arm A before the train is turned around, the touch arm A moves to the position of the touch arm B before the train is turned around, although the position of each touch arm is changed, the overall position of the touch arms is not changed relative to the reference system on the ground, the design form can ensure timely turning around of the open wagon, and the functions of the touch arms before and after turning around are kept unchanged.

For convenience of description, the two ends of the truck are divided into a first end provided with the first top cover 101 and a second end provided with the second top cover 102, and the first end and the second end are illustrated in the south-east-west-north directions. In general, there are three ways for a gondola to enter a discharge site for unloading: in the first situation, the open wagon drives into a discharging place from south to north, drives away from the discharging place from north to south after discharging is completed, the first end is always positioned on the side close to north in the whole process, and the second end is always positioned on the side close to south, in other words, the open wagon does not turn around when discharging; in the second situation, the open wagon drives into the unloading site from south to north, drives away from the unloading site from north to south after unloading is finished, the first end is positioned on the side close to north when entering the unloading site, the second end is positioned on the side close to south, when leaving the unloading site, the first end is positioned on the side close to south, and the second end is positioned on the side close to north, in other words, the open wagon turns around after unloading is finished; and in the third situation, the open wagon drives into the unloading site from south to north, continues to drive from south to north and drives away from the unloading site after the unloading is finished, and the first end is always positioned on the side close to north and the second end is always positioned on the side close to south in the whole process, namely, the open wagon equivalently passes through the unloading site.

Preferably, the number of the touch arms on each roof unit 100 is one, the touch arms on two roof units 100 are respectively arranged on two sides of the top of the cargo compartment, and the following detailed description is made on the working process of the touch arms in combination with the actual situation:

the first condition is as follows: the first end of the open wagon is located on the north side, the touch arm A on the first top cover 101 is located on the west side of the top of the cargo compartment, the touch arm B on the second top cover 102 is located on the east side of the top of the cargo compartment, and the cover shifting device D is arranged on the east side of the railway. The open wagon runs from south to north to enter a discharging place, the movable top cover is in a closed state before running, and when the open wagon passes through the cover shifting device 300, the cover shifting device D is in contact with the touch arm B, so that the second top cover 102 is folded and contracted, and meanwhile, the first top cover 101 is driven to be folded and contracted through the linkage mechanism, and the opening of the movable top cover is completed. After the unloading is finished, the movable top cover is in an open state, when the movable top cover drives away from the unloading place from north to south and passes through the cover-shifting device 300, the cover-shifting device D is contacted with the touch arm B, so that the second top cover 102 is unfolded, and meanwhile, the linkage mechanism drives the first top cover 101 to be unfolded, and the movable top cover is closed.

Case two: after the open wagon is turned around, the positions of the touch arm A and the touch arm B are exchanged, the second end of the open wagon is located at the north side, and the opening and the closing of the movable top cover are still completed according to the process in the first case.

Case three: the first end of the truck is located on the north side, access to the unloading site and the process of opening the movable roof is the same as in case one. After the unloading is finished, the open wagon continues to run from south to north along the track and drives away from the unloading place, the cover-pulling device C arranged on the west side of the railway contacts with the touch arm A to enable the first top cover 101 to be unfolded, and meanwhile, the linkage mechanism drives the second top cover 102 to be unfolded to finish the closing of the movable top cover. In other words, the cover-shifting device D is used for opening the movable top cover, the cover-shifting device C is used for closing the movable top cover, and meanwhile, due to the fact that the touch arms are arranged in a central symmetry mode, the functions of the cover-shifting devices C and D are not changed all the time no matter the open wagon is turned around or not.

It should be understood that the directions of southeast, northwest, etc. referred to in the above description of cases one, two, and three are only for convenience of description and understanding, and do not serve any limiting purpose.

Preferably, referring to fig. 1 and 2, each roof unit 100 is provided with two touch arms, and the two touch arms on the same roof unit 100 are respectively disposed on two sides along the width direction of the cargo compartment; accordingly, the cover-pulling devices 300 are also provided in pairs on both sides of the railway track, corresponding to the two touch arms when the movable cover is opened or closed, respectively. Because the movable top cover is limited by weight and structure, the force provided by the touch arm is limited, and for the condition that the whole weight of the movable top cover is larger, the opening or closing force is insufficient due to the arrangement of only one set of the cover-pulling device 300 and the touch arm; meanwhile, due to the structural limitation of the cover-pulling device 300, the contact point of the cover-pulling device 300 and the contact point of the contact arm are abutted against the two sides of the width of the open wagon cargo compartment, one cover-pulling device 300 is arranged, and acting force is only applied to the contact arm on one side of the movable top cover, so that the sliding of the two sliding rails 200 of the movable top cover is not matched, and the situation of blocking or unsmooth sliding is caused. The two touch arms are arranged, so that on one hand, acting force for opening or closing the movable top cover can be increased, on the other hand, force can be simultaneously applied from two sides of the movable top cover, and asynchronous sliding of the sliding mechanisms 140 at the two sliding tracks 200 is avoided.

In some embodiments, the plurality of touch arms are offset along the width of the truck. For example, the touch arm on the first cover 101 is disposed at a middle position, and the touch arm on the second cover 102 is disposed at a position near both ends of the end beam 130. The lid-pushing mechanism 330 extending downward from above can be set at different positions and touch the touch arm at a specific position to complete a predetermined lid opening and closing operation.

In some embodiments, the plurality of touch arms are offset along the height of the truck. For example, the touch arm on the first cover 101 extends upward by 20CM, the touch arm on the second cover 102 extends upward by 10CM, and there is a certain height difference between the two touch arms. The height of the cover-moving mechanism 330 is adjusted and the touch arm with a relatively long extension is touched to complete the predetermined cover opening and closing action.

Preferably, referring to fig. 2 and 3, the upward side of the end beam 130 is a mounting surface, and the touch arms are fixedly connected to the mounting surface. For example, the end cross member 130 is made of a square pipe, both ends of which are fixedly connected to the sliding mechanisms 140 at the ends of the two cover units 110, and one side of the square pipe faces upward to serve as a mounting surface; meanwhile, the portion of the flip device 300 that contacts the touch arm may be considered to extend from top to bottom above the truck. Because the movable top cover unit 100 is stressed and guides the sliding of the whole top cover unit 100, the structural volume of the sliding mechanism 140 at the end part is generally larger, and in order to avoid the cover-pulling device 300 from extending into the sliding mechanism 140 from the side, a touch arm is arranged on the top surface of the end part cross beam 130, the cover-pulling device 300 is designed from top to bottom, and the touch arm which is not touched when the cover-pulling device 300 extends into the sliding mechanism from the side can be avoided. In addition, the touch arm can be arranged to be deviated to the top center of the cargo compartment, so that the moment generated to the end cross beam 130 due to the contact force of the touch arm and the cover pulling device 300 is reduced.

Preferably, the touch arms are disposed on both sides of the cover unit 100, and accordingly, the cover-pulling device 300 is close to the open wagon from the side and contacts the touch arms. In order to simplify the structure of the cap removing device 300 and reduce the height of the cap removing device 300, a touch arm may be disposed on a side surface of the top cover unit 100.

Specifically, each roof unit 100 is provided with one touch arm, and the two touch arms are disposed on two sides of the open wagon. For example, in a truck traveling from south to north, the touch arm a on the first cover 101 is disposed on the west side, the touch arm B on the second cover 102 is disposed on the east side, and the heights of the touch arm a and the touch arm B are the same. Since the two roof units 100 are of a split design and provided with a linkage, the touch arms a and B can be considered to be symmetrically arranged along the geometric center of the top of the cargo box. The operation principle of the touch arm disposed on the side of the top cover unit 100 is the same as that of the touch arm disposed on the top of the top cover unit 100, and is not described herein again.

Preferably, since the end of the movable top cover unit 100 is stressed and guides the sliding of the whole top cover unit 100, the sliding mechanism 140 at the end is generally bulky, and the touch arm can be disposed at the side of the sliding mechanism 140 to simplify the structure of the top cover unit 100.

Referring to fig. 1 and 3, the movable cover includes a mounting frame 800, a cover unit 100, a sliding rail, and a cover-pulling device 300:

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 a protruding section of the first rail 210 protruding from the open wagon load compartment 900 and bent downward. When the roof unit 100 is in the folded state, it can be fully retracted within the second rail 220 or the second and third rails 220 and 230, so that the top of the cargo compartment 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 can avoid the situation that the distance between two adjacent cargo cars 900 is shortened and even interfered because the protruding section of the first rail 210 protruding the cargo car 900 is too long.

The above-mentioned retraction of the roof unit 100 to the protruding section of the first rail 210 protruding out of the open wagon 900 or the retraction of the roof unit into the second rails 220 disposed at the two end sides of the extension direction of the wagon 900 is to fully open the top of the wagon 900. For a railway truck, particularly a truck for transporting bulk materials such as coal, stone, etc., the truck usually has its cargo bed 900 turned 180 ° by a tippler to dump the cargo bed 900. If the roof unit 100 is not fully opened after being retracted, the cargo compartment 900 will be at a low rate of dumping, and the cargo will impact the roof unit 100 when dumped, which may damage the roof unit 100.

In some embodiments, the movable split top cover with the linkage mechanism is provided with a stop mechanism only on one of the top cover units 100, and the stop mechanism on the first top cover is taken as an example for explanation. When the open wagon is operated, the roof unit 100 is in a closed state, and the end provided with the second roof first passes through the cover-pulling device 300, and since the second roof is not provided with the stopper mechanism, the front half part of the cargo compartment 900 does not collide with the cover-pulling device 300. When the rear half part of the cargo compartment 900, i.e. the part enclosed by the first top cover, passes through the cover-pulling device 300, the cover-pulling device 300 collides with the stop mechanism on the movable end of the first top cover, and drives the first top cover to fold and move relative to the cargo compartment 900; meanwhile, the first top cover drives the second top cover to move through the linkage mechanism, the two top covers have the same moving speed and opposite directions. When the first roof is fully folded and contracted, the second roof is also simultaneously folded and contracted, so that the top of the cargo box 900 is fully 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 a linkage mechanism, 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 top car is driven from south to north, the first top cover is located at the end of the cargo compartment 900 near the north, i.e. when the open top car passes through the cover-shifting device 300, the first top cover first passes through the cover-shifting device 300, the stop mechanism on the first top cover is arranged at the west side of the open top car, and the stop mechanism on the second top cover is arranged at the east side of the open top car. 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 cover on 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 to complete the opening of the top cover unit 100. After the open wagon is unloaded, the open wagon continues to run from south to north (the north and south directions are marked by arrows in the drawing), and the cover closing cover shifting mechanism passes through the north part of the unloading place and is arranged on 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, only collides with the stop mechanism positioned on the west side on the first top cover, drives the first top cover to expand, and simultaneously drives the second top cover to expand through the linkage mechanism, thereby completing the closing of the top cover unit 100.

Preferably, referring to fig. 2, the linkage mechanism includes driving wheels, annular driving members and end beams, and the two driving wheels are disposed at two ends of the cargo compartment 900 along the length direction; the annular transmission medium sets up on two drive wheels to can rotate round the drive wheel, the annular transmission medium position is comparatively by half one and is the upside transmission medium, the transmission medium that the position was comparatively leaned on is the downside transmission medium, two top cap unit 100's tip crossbeam fixed connection respectively in upside transmission medium and downside transmission medium. For example, the first top cover is connected to the upper side transmission member, the second top cover is connected to the lower side transmission member, and when the first top cover is folded to open the top cover unit 100, the cross beam at the end of the first top cover moves leftwards to drive the upper side transmission member to move leftwards, so that the annular transmission member rotates anticlockwise. Simultaneously, the lower side transmission part moves rightwards and drives the cross beam at the end part of the second top cover to move rightwards, 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.

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.

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 compartment 900 when the roof unit 100 is opened, preventing foreign objects from entering the cargo compartment 900 or preventing cargo in the cargo compartment 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 comprises a lock body and a lock tongue which are respectively arranged 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 the lock tongue and the lock body are not subjected to the force exceeding a certain magnitude, the lock tongue and the lock body are kept in a locking 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.
