[0004] In the traditional container transportation loading and unloading system, the traction and migration of the train carriages are completed by the heavy car traction machine, the empty car traction machine and the migration car platform on both sides of the migration car pit, which requires a large parking space for the equipment and has high maintenance costs. The unloading of the container is also carried out by the general conventional container lifting device currently used, which often only has a single lifting or overturning function, and cannot lift and overturn the containers densely stacked together, resulting in low operation efficiency.

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

The terms "mounting", "setting", "connecting", "fixing", "screwed", and the like should be understood broadly, for example, can be fixedly connected, can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0049] The present application provides a method for collecting and transferring a plurality of vehicles, comprising the steps of: Figures 1 to 13The train container unloading system comprises a train pulling device 60 for pulling the train carriage to move, a turnover device 70 for hoisting and overturning the container, a carriage moving platform 80 for the train pulling device and the train to move, when the train pulling device 60 drives the train carriage to move to the first position, the turnover device 70 hoists and overturns the container on the train carriage, when the train pulling device 70 drives the train carriage to move to the second position, the train pulling device 70 and the train carriage can move on the carriage moving platform 80 in a direction different from the previous direction.

[0050] In the present application, by integrating the traditional heavy train pulling, empty train pulling, container hoisting, container unloading, empty train pushing and other operation processes in one system, the above operation processes can be completed in a centralized area, the overall efficiency is improved, and the site space is saved.

[0051] As shown in Figure 2 The installation structure diagram of the turnover device 70 is shown, the periphery adopts a steel structure to form a gantry, the whole turnover device 70 is installed on the gantry beam through the upper fixed frame 701, the beam has a device for moving the whole turnover device 70 in the transverse direction, such as a motor drive, a gear drive, an oil cylinder drive and the like. The transverse movement of the turnover device 70 is to move to the above of the material collecting and transferring system 1000 after hoisting the container, and then perform the unloading operation.

[0052] As shown in Figures 3 to 5As shown, the fixed frame 701 is composed of beams arranged oppositely and is in a cuboid structure, and the upper end of the longitudinal beam is connected to the rectangular frame 7105 composed of beams. The fixed frame 701 can be manufactured by casting or welding. The intermediate turnover frame 704 for driving the container to overturn is arranged below the fixed frame 701; the top of the intermediate turnover frame 704 is composed of two beams connecting two side wall beams 7405, which are approximately inverted U-shaped structures. At the four beam end positions of the two inverted U-shaped side wall beams 7405 downward, a rectangular frame is connected, and four short beams are arranged downward at the four corner positions of the rectangular frame. The lifting tool 7015 for grabbing and hoisting the container is arranged below the intermediate turnover frame 704; the lifting tool 7015 is a rectangular structure composed of beams, and upward protrusions 70408 are arranged at the four corner positions. The function of the protrusions 70408 is that when the lifting tool 7015 gradually approaches the intermediate turnover frame 704 during the contraction process of the lifting device 702, the protrusions 70408 first contact the top of the intermediate turnover frame, which plays a limiting role, and at the same time can avoid the direct contact between the lifting tool 7015 and the intermediate turnover frame 704, thereby reducing the deformation of the lifting tool 7015. The intermediate turnover frame 704 is connected with the lifting tool 7015 through the lifting device 702; one end of the lifting device 702 is fixed on the inverted U-shaped side wall beam 7405 of the intermediate turnover frame 704, and the other end is connected with the inner side wall of the upper beam of the lifting tool 7015. The lifting device 702 transmits the power provided by the power device to the lifting tool 7015 through the transmission mechanism 7115, thereby driving the lifting tool 7015 to move up and down relative to the intermediate turnover frame 704. The turnover structure 703 is arranged at the connection position of the fixed frame 701 and the intermediate turnover frame 704, which can make the intermediate turnover frame 704 overturn relative to the fixed frame 701. The connection mode of the intermediate turnover frame 704 and the fixed frame 701 is shaft connection. Figure 3As one embodiment of the present invention, a protruding shaft is provided on the beam of the intermediate flipping frame 704 to engage with a through hole provided at the lower end of the fixed frame 701. Alternatively, a through hole can be provided on the beam of the intermediate flipping frame 704 to engage with a protruding shaft provided at the lower end of the fixed frame 701, thereby enabling the intermediate flipping frame 704 to flip relative to the fixed frame 701. The flipping of the intermediate flipping frame 704 relative to the fixed frame 701 occurs along the axis formed by the connecting axis of the two frames. The virtual straight line formed by connecting the centers of the two short axes is the flipping axis of the intermediate flipping frame 704 relative to the fixed frame 701, and the flipping direction can be to either side. The flipping structure 703 allows the intermediate flipping frame 704 to flip relative to the fixed frame 701 to at least a first position and a second position. The first position, where the intermediate flipping frame 704 is not flipped relative to the fixed frame 701, has a flip angle of 0°, at which point the lifting device 702 can operate. The second position, where the intermediate flipping frame 704 flips relative to the fixed frame 701, is used for unloading cargo. The intermediate flipping frame 704 can be configured in various frame forms, primarily serving to provide structural force to secure the container and connect the lifting device 7015 during flipping. The lifting device 702 includes a pulley block 7206 and a transmission structure 7115. In the embodiment shown in this figure, the transmission structure 7115 is a wire rope, which works in conjunction with the pulley block 7206. This is one embodiment of the present invention. The lifting device 702 can also be directly driven by a wire rope or chain, or by a hydraulic cylinder, etc. The main function of the lifting device 702 is to lift the lifting device 7015 relative to the intermediate tilting frame 704 by external force. Other methods can achieve this effect and can also be used as embodiments of the present invention. The upper end of the lifting device 702 is arranged opposite to each other on the inner side wall of the vertical beam of the intermediate tilting frame 704. In this embodiment of the present invention, the lifting device 702 consists of four sets of pulley groups 7206 arranged opposite to each other and a transmission structure 7115. The actual transmission mechanism 7115 used is a wire rope. The advantage of this design is that it can correspond to the positions of the pulleys at the four corners of the lifting device 7015, which is beneficial to the overall stability during the lifting process. The lower end of the lifting device 702 is positioned opposite to the inner side wall of the beam of the lifting device 7015. When the lifting device 702 is subjected to external force, it can extend or shorten the transmission structure 7115. This allows the lifting device 7015 to move up and down relative to the intermediate tilting frame 704. The lifting device 702 adjusts the length of the transmission structure 7115 to drive the lifting device 7015 to move up and down. The lifting stops when the protrusion 70408 of the lifting device 7015 contacts the intermediate tilting frame 704. The tilting structure 703 is a gear-driven mechanism. By setting meshing gears on the intermediate tilting frame 704 and the fixed frame 701, the relative tilting between the two can be achieved through gear transmission.The intermediate turnover frame 704 is driven to turn by at least one pair of intermeshing gears, which is a gear meshing mode of the embodiment of the application, and can also be provided as a multi-stage gear meshing. The spreader 7015 is in the overall rectangular structure, which is made of profiled material, and the lower part of the spreader 7015 is provided with a lock head device 7010 for grabbing the container. The function of the spreader 7015 is to grab and unload the container through the lock head device 7010, and when the container is grabbed, the lifting device 702 is used to lift the container into the intermediate turnover frame 704. The turnover structure 703 is composed of at least one of the following driving mechanisms: gear combination driving, chain wheel and chain driving, oil cylinder pushing, motor driving, and speed reducer driving. The embodiment of the application shows the gear combination driving of the turnover structure 703, and other ways to achieve the turnover effect can also be used as the embodiment of the application. The intermediate turnover frame 704 is provided with a container side support rod 706 for providing support force for the side beam of the container in a movable connection manner, and the container side support rod 706 is at least one group, which provides support force for the side beam of the container when the intermediate turnover frame 704 turns. The side support rod 706 is used to prolong the force arm of the intermediate turnover frame 704 on the container when the intermediate turnover frame 704 turns, so as to reduce the risk of uneven deformation of the container body, and at the same time, the side support rod 706 does not generate force on the container when the intermediate turnover frame 704 does not turn, so that the spreader 7015 is not affected when grabbing the container to lift.

[0053] As Figure 3 When lifting the container, the lifting device 702 starts to shorten the transmission structure 7115 by the action force of the power device, and since the upper and lower ends of the lifting device 702 are connected to the intermediate turnover frame 704 and the spreader 7015 respectively, at this time, with the shortening of the transmission structure 7115, the spreader 7015 grabbing the container through the lock head device 7010 also rises relative to the intermediate turnover frame 704 with the shortening of the transmission structure 7115, and when the upper end protrusion 70408 of the spreader 7015 contacts the top inner wall of the intermediate turnover frame 704, the lifting device 702 stops tightening, and the lifting process of the container is completed.

[0054] As Figure 5As shown, after the container is lifted, the overturning structure 703 is started, the intermediate overturning frame 704 is overturned as a whole along the virtual axis formed by the fixed frame 701 and the intermediate overturning frame 704 connecting shaft through internal gear engagement transmission, the lifting appliance 7015 is subjected to the traction force of the transmission structure 7115, so that the top protrusion 70408 is tightly attached to the top inner wall of the intermediate overturning frame 704, while the intermediate overturning frame 704 is overturned, the side support rod 706 provides support force to the side beam of the container, relieving the uneven overturning force of the intermediate overturning frame 704 on the container, the overturning of the intermediate overturning frame 704 drives the overturning of the container, and the dumping of the goods is completed.

[0055] In the present application, by concentrating the container lifting device 702 and the overturning structure 703 into a set of devices, when the power mechanism is connected, the overturning structure 703 and the lifting device 702 can work through power transmission, thereby completing the lifting and overturning operation of the container, and meanwhile, the whole overturning and unloading device provided by the present application can be connected to other designed multiple scenes for use, and the application range is wide.

[0056] As Figures 6 to 7 The present application provides a car transfer platform 80, which comprises a bearing device 801. The whole car transfer platform 80 is arranged on a car transfer platform basic frame 80101, one end of which is connected to a rail of a train carriage loading and unloading station, and the train carriage can be directly moved from the loading and unloading station to the bearing device 801 under the action of an external force. A displacement device 802 is arranged below the bearing device 801. The displacement device 802 mainly drives the bearing device 801 to displace in the width direction of the train carriage through its own displacement structure when the train is parked on the bearing device 801, thereby driving the train to displace synchronously, and the displacement device 802 does not drive the train to displace in the length direction of the train.

[0057] As Figures 8 to 11 The present application provides a car transfer platform 80, which comprises a bearing device 801. The whole car transfer platform 80 is arranged on a car transfer platform basic frame 80101, one end of which is connected to a rail of a train carriage loading and unloading station, and the train carriage can be directly moved from the loading and unloading station to the bearing device 801 under the action of an external force. A displacement device 802 is arranged below the bearing device 801. The displacement device 802 mainly drives the bearing device 801 to displace in the width direction of the train carriage through its own displacement structure when the train is parked on the bearing device 801, thereby driving the train to displace synchronously, and the displacement device 802 does not drive the train to displace in the length direction of the train.

[0058] The one end of the car pulling arm structure 804 is hinged on the hinge seat 60108 on the main beam structure 601, and the other end is provided with the first car hook assembly 616 for hooking the train; the hinge seat 60108 can be provided on the main beam structure 601 by welding or other movable connection modes such as riveting or threaded bolt fixed connection.

[0059] In the present application, the one end of the car pulling arm structure can be connected with a telescopic arm, the other end of the telescopic arm is sleeved in the fixed arm body, and the telescopic arm can be telescopically moved in the fixed arm body. In different working environments, the length of the whole car pulling arm structure 804 can be adjusted by adjusting the sleeving depth of the telescopic arm and the fixed arm body.

[0060] The hinge seat 60108 is provided with a hinge hole, and the car pulling arm structure 804 is hinged with the hinge seat 60108 by coupling the hinge hole at the end of the car pulling arm structure 804 with the hinge seat 60108 and then fixed by a hinge pin. The important role of the car pulling arm structure 804 is to transmit power to pull the train, so the other end of the car pulling arm structure 804 is provided with the first car hook assembly 616 for hooking the train. As a more optimal design, the other end of the car pulling arm structure 804 can also be connected with the second car hook assembly 619. The two sets of car hook assemblies can flexibly meet the construction requirements of different scenes, the two traction hook assemblies can independently pull the car, have independent car hook lifting systems, and the traction hook devices can be used as backup for each other.

[0061] In the present application, the pitch mechanism 805 for rotating and lifting the car pulling arm structure 804 is also provided; the car pulling arm structure 804 is rotated at a set angle around the hinge seat 60108 under the action of the pitch mechanism 805. When the one end of the car pulling arm structure 804 is hinged on the hinge seat 60108, the pitch mechanism 805 at the other end provides power to the car pulling arm structure 804, so that the car pulling arm structure 804 rotates around the hinge hole of the hinge seat 60108 as the center, and the rotation angle is set according to different working conditions (or the length of the pitch mechanism arm).

[0062] In the present application, the wheel device 604 is also included, and the wheel body part of the wheel device 604 abuts against the track, so that the whole car pulling device 60 is attached to the track for displacement. The wheel device 604 is mainly responsible for the walking support and guidance of the whole car pulling device 60, so that the car pulling device 60 does not deviate from the track when pulling the car. At the same time, the wheel device 604 receives the reaction force at the abutting place of the track, which limits the running track of the car pulling device 60 to coincide with the track arrangement.

[0063] The power device 608 is composed of a reduction motor arranged on the main beam structure 601. As a more optimal effect scheme, the reduction motor can be arranged in groups on the main beam structure 601. In the application, a plurality of reduction motors are arranged as walking power devices, and as an alternative scheme, a hydraulic motor or the like can be used. As shown in the figure, the motor groups are symmetrically distributed on the main beam structure 601, and the driving force generated when the towing vehicle is towed can be uniformly distributed on the main beam structure 601, and the resultant force is uniformly transmitted to the towing arm structure 804, so as to ensure that the towing machine runs stably and does not deviate. Figure 10

[0064] In the application, the driving device 603 includes a rotating shaft 60205 engaged with the motor driving shaft of the power device 608; a gear 60306 arranged below the rotating shaft 60205; and a rack structure 60408 fixedly arranged on the inner side of the main beam structure 601. The motor driving shaft and the rotating shaft 60205 are connected through a helical gear, the gear 60306 is arranged below the rotating shaft 60205, and the gear 60306 is engaged with the rack structure 60408. When the power device 608 drives the rotating shaft 60205 to rotate, the gear 60306 below the rotating shaft 60205 also rotates, and since the rack 60408 engaged with the gear 60306 is fixedly arranged on the track, the whole towing device 60 can realize walking displacement relative to the rack 60408 when the gear 60306 and the rack 60408 are engaged.

[0065] The tilting mechanism 605 in the application is composed of a hydraulic oil cylinder 60501; the bottom of the hydraulic oil cylinder 60501 is movably connected to the main beam structure 601, and the telescopic end of the hydraulic oil cylinder 60501 is connected to the towing arm structure 804. This design scheme can drive the towing arm structure 804 to approach the main beam structure 601 infinitely through the contraction of the hydraulic oil cylinder 60501 when the towing arm structure 804 does not need to be towed. As another alternative scheme, the towing arm structure 804 can be directly fixedly connected to the main beam structure 601, which has a slightly higher requirement for the track space, but can also realize the towing operation process.

[0066] In the application, a guide wheel 6011 is further arranged on the inner side of the main beam structure 601. The guide wheel 6011 can increase the rolling friction between the main beam structure 601 and the track during the running of the towing machine, so as to ensure that the towing machine runs stably.

[0067] ​In the present application, when the pitch mechanism 605 is in the retracted state, the towing device 60 can pass through the space formed by the carriages of the train to be towed and the main beam structure 601. The overall design size of the towing device 60 satisfies that when the hydraulic cylinder of the pitch mechanism 605 is fully retracted, the overall height is lower than the longitudinal height between the train carriage and the track, so that the towing device 60 can freely hide under the train carriage on the track when not towing the train. The specific design size can be designed according to the above principle under different working conditions.

[0068] As an alternative to this part of the application, the connection between the towing arm structure 804 and the main beam structure 601 can also be designed as a swing arm, or a parallelogram linkage, or a telescopic lifting form similar to a crane arm; in addition, the driving mode can be designed as gear and rack, chain wheel and chain, steel wire rope transmission and the like, and the specific design idea is consistent with the overall idea of the present application, which will not be repeated here.

[0069] In use, the reduction motor of the power device 608 is started, the motor transmission shaft transmits power to the rotating shaft 60205 through the helical gear, the rotating shaft 60205 drives the gear 60306 sleeved below the rotating shaft 60205 to rotate, the gear 60306 is engaged with the rack 60408, and the rack 60408 is fixedly arranged on the track, so that the rack 60408 provides a reverse force to the gear 60306, and drives the overall towing device 60 to move. When the pitch mechanism 805 is retracted to different degrees, the towing arm structure 804 is driven to rotate around the hinge hole of the hinge seat 60108 as the axis, so as to match the towing height of different carriages and tow. The towing arm structure 804 is designed as a telescopic arm, which can tow carriages at different positions.

[0070] The car pulling device 60 hooks and pulls the train after the train carriage unloads the material, and the train can be displaced in at least two directions through the traction and displacement movement of the car pulling device 60 and the displacement device 802. In the entire car pulling platform basic frame 80101, the present application designs to concentrate the train traction operation and the empty car lane pushing into an overall operation interval, hooks the train through the car pulling arm structure 804 connected to the car pulling device 60, then pulls the train along the length direction of the train to the load bearing device 801, and then displaces the load bearing device 801 and the train as a whole along the width direction of the train through the displacement device 802. The part of the car moving platform 80 involved in the present application has a compact structure, and the heavy car pulling machine and the empty car pulling machine are integrated into an overall car moving platform, which simplifies the equipment; at the same time, the heavy car pulling machine and the empty car pulling machine are reduced, the use of land on both sides of the train track is reduced, and the land utilization rate is higher; in addition, the car pulling device 60 is arranged on the car moving platform, and the traction equipment for heavy cars and empty cars does not need to be replaced, which reduces the hooking and unhooking process of the train once, saves time, and improves production efficiency; the car pulling device 60 always maintains traction on the train during the entire transverse car moving process of the train, which can greatly improve the stability of the car moving process of the train.

[0071] The load bearing device 801 is used to bear the weight of the train, the car pulling device 60 connects the train through the car pulling arm structure 804 to displace along the length direction of the train, and the displacement device 802 displaces along the width direction of the train to drive the load bearing device 801 to displace correspondingly. As described above, after the car pulling arm structure 804 hooks the train, the car pulling device 60 moves relative to the load bearing device 801 to drive the car pulling arm structure 804 and the train to move together onto the load bearing device 801, which is the first movement trajectory direction of the train, and is along the length direction of the train. When the displacement device 802 drives the load bearing device 801 and the train to move together, it is along the width direction of the train.

[0072] The load bearing device 801 is composed of two oppositely arranged steel rails; the steel rails are matched and connected with the train loading and unloading site track, and the train can freely pass above the steel rails; similarly, as another embodiment, the steel rails can be directly extended below the loading and unloading site to achieve the technical effects of the present application. The car pulling device 60 is arranged in the space formed inside the two steel rails of the load bearing device 801, and the car pulling device 60 can displace along the length direction of the train. The car pulling device 60 mainly pulls the train to move, and since the steel rail track of the load bearing device 801 has a certain height, i.e. the overall part of the car pulling device 60 is arranged in the space generated by the height, the car pulling device 60 can pass through the car moving platform when not pulling the train, without affecting the movement of the train above it. At the same time, it is convenient to pull the train to move along the track of the load bearing device 801, and space is saved.

[0073] The car pulling arm structure 804 is a shunting arm structure, and a hooking and pulling hook for hooking and pulling the train is arranged at the end of the shunting arm structure. The car pulling arm structure 804 is mainly used for transmitting the force of the car pulling device 60 to the train, and the car pulling arm structure 804 has the function of hooking the train. In the embodiment of the present application, the car pulling arm structure 804 is designed as a shunting arm structure, and the lower end of the shunting arm structure is hinged to the car pulling device 60. The shunting arm structure can perform a certain angle of circumferential motion by rotating around the hinge hole, so as to adapt to the hooking requirements of trains of different heights. The top end of the shunting arm structure is also designed with a through hole, which can be matched with a car pulling hook assembly of different sizes to ensure the hooking of the train under different operation requirements.

[0074] In the present application, the displacement device 802 is a transverse moving trolley, which moves in the width direction of the railway. The displacement device 802 can drive the transverse moving trolley to move through an external power system. The top structure of the transverse moving trolley has a substantially flat surface for bearing the weight of the load bearing device 801 and the train. A groove is arranged in the middle of the structure to facilitate the passage of the car pulling device 60. Rollers are arranged at the bottom of the structure, which can cooperate with different track operations.

[0075] The car pulling arm structure 804 is movably connected to the car pulling device 60. The car pulling arm structure 804 can be retracted into the inside space of the load bearing device 801, so as not to affect the passage of the train above the load bearing device 801 when the train is not being pulled. The car pulling arm structure 804 can also be fixedly connected to the car pulling device 60, which will be limited by the rotation angle of the shunting arm, thereby limiting the hooking of a certain fixed size of train. When the car pulling arm structure 804 is movably connected to the car pulling device 60, it is connected by a hinge. The car pulling device 60 is provided with a hinge hole for cooperating with the shunting arm.

[0076] The connection form of the shunting arm structure and the car pulling device 60 is composed of at least one of the following connection forms: swing arm form, parallelogram linkage form, telescopic lifting form of crane jib. The main function of the shunting arm is to transmit force, so that the pulling device 60 can pull the train to move.

[0077] When the car pulling arm structure 804 is fully extended in the pitching mechanism 805, it has a height higher than the load bearing device 801. Through the movement of the car pulling device 60, it can stay at any position relative to the car moving platform 80. The transverse moving trolley is located directly below the steel rail of the load bearing device 801 and bears the weight thereof. The steel rail is designed as two parallel rails, which is connected with the train rail. By configuring a rail suitable for the transverse moving trolley below the transverse moving trolley, the transverse moving trolley can move in the width direction of the train.

[0078] As Figure 12As shown, the car migration operation process after the loading and unloading of the present technical scheme is as follows: when the loading and unloading of the train carriage is completed, the loading and unloading station 80303 is reached, at this time, the train pulling device 60 located on the car migration platform base frame 80101 is moved to the vicinity of the loading and unloading station 80303, the train hook is taken through the traction hook at the top of the shunting arm, the power unit 60505 is started at the same time, so that the train pulling device 60 moves away from the loading and unloading station 80303, thereby driving the train to move to the load-bearing device 801 through the shunting arm. Then, the train pulling device 60 pulls the train to stop at the corresponding position, the external power structure of the displacement device 802 is started to drive the load-bearing device 801 and the train to move in the width direction of the train, and when the train reaches the car returning track 80308, the shunting arm is unhooked from the train, and the train is pushed to the car returning track through other power devices; or the structure of the train pulling device 60 can be improved, and when the train is driven to the car returning track 80308 by the transverse moving trolley, the train pulling device 60 has a pushing force to push the train into the car returning track, so that the overall structure design is simplified and the work process is reduced.

[0079] The above design layout can be changed in position and direction of each component during on-site construction according to the specific construction site conditions, and the overall design concept is the same, and has flexibility.

[0080] As shown in the figure, Figure 4 The structure principle has been described above.

[0081] In use, when the loading and unloading of the train carriage is completed, the loading and unloading station 80303 is reached, at this time, the train pulling device located on the car migration platform base frame 80101 is moved to the vicinity of the loading and unloading station 80303, the train hook is taken through the traction hook at the top of the shunting arm, the power unit 60505 is started at the same time, so that the train pulling device 60 moves away from the loading and unloading station 80303, thereby driving the train to move to the load-bearing device 1 through the shunting arm. Then, the train pulling device 60 pulls the train to stop at the corresponding position, the external power structure of the displacement device 802 is started to drive the load-bearing device 801 and the train to move in the width direction of the train, and when the train reaches the car returning track 80308, the shunting arm is unhooked from the train, and the train is pushed to the car returning track.

[0082] According to the principle of the present application, the present loading and unloading system can also be designed as a double turnover system, and two groups of train carriages can be loaded and unloaded, and the principle is consistent with that of the single turnover device. The following describes one of the operation processes.

[0083] The whole operation process of the present application is as follows: when in use, the locomotive or other power device pushes the whole train into the system, and pushes the train carriages to be unloaded into the range of the towing device, at which the double-stable device can be arranged to clamp the wheel body of the train carriage, at this time, the locomotive or other power device uncouples and leaves the operation area. The shunting arm structure 804 on the towing device falls down, and is connected with the train carriage through the towing hook assembly and the train carriage, and the clamping wheel is released. The towing device pulls the train carriage to move forward, and when the first and second carriages enter the position below the turnover device, the third train carriage is braked when moving to the position close to the end ring of the turnover device, and the clamping wheel clamps the wheel of the third train carriage; the third train carriage and the second train carriage in front are uncoupled by manual operation; the towing device 60 pulls the first and second train carriages to continue moving forward, and is braked when reaching the turnover loading and unloading position, and then is uncoupled; when the towing device leaves the loading and unloading position, the turnover device starts to lift and turn the container. Then the towing device returns to the vicinity of the train carriage to be unloaded, and the above operation is repeated. The unloaded container is put back into the train carriage by the turnover device, the towing device moves on the train moving table, pulls the empty train carriage to the empty train line, and stops after aligning, and then pushes the empty train carriage to make it pass through the one-way stopper and stop on the empty train line; the displacement device leads the whole train carriage to move transversely, and waits for other locomotives or power devices to pull the empty train carriage to leave. The above operation is repeated until the whole train carriage is unloaded completely.

[0084] The present application also provides a train container unloading method, which comprises the following steps: pulling the train carriage loaded with containers to a first position; lifting and turning the containers to unload; putting the unloaded containers back into the train carriage; pulling the train carriage to a second position; and moving the train carriage transversely approximately perpendicular to the previous moving direction.

[0085] When in use, when the train carriage reaches the designated unloading site, the train carriage is pulled by the towing device to the position below the turnover structure, at which the containers are lifted. Then the turnover device moves the containers above the unloading area through transverse displacement; then the containers are turned to unload into the unloading hopper and the belt conveyor or other material conveying equipment; then the containers are moved back to the original position by the turnover device; then the towing device pulls the train carriage after unloading to above the train moving table; the train carriage changes the previous moving direction on the unloading line and moves transversely to the empty train line; then the train carriage on the empty train line is pushed and pulled.

[0086] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application.
