Description

Technical Field

[0001] This utility model relates to the technical field of container unloading equipment, specifically to a tilting mechanism and a container tilting and unloading device. Background Technology

[0002] Currently, bulk cargo transported by rail is mainly done in open wagons, but a significant portion is also transshipped via containers. Specifically, containers are loaded into open wagons for transshipment. Because bulk cargo can be lifted and loaded onto wagons along with containers, the loading and unloading efficiency is higher, leading to a substantial increase in the volume of bulk cargo transported by rail in recent years.

[0003] In the existing technology, the hoisting-type tilting and unloading equipment for open-top containers on trains adopts a combination of overhead crane, trolley, fixed frame and rotating frame to tilt and unload open-top containers mounted on train flatbeds. However, due to the limited tilting space required, the fixed frame and trolley occupy a large amount of height space, which cannot be effectively carried out in space-constrained scenarios.

[0004] In view of this, how to improve the container tipping and unloading device to solve the problem of unloading containers in low-ceilinged spaces is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] To address the problems of limited space and inconvenient operation in the existing container hoisting technology, this utility model provides a tilting mechanism for unloading container materials. It includes a tilting component and fixed supports located at both ends of the tilting component. The top of the fixed support is provided with at least two traveling wheels, which are arranged on both sides along the rotation axis of the tilting component. The tilting component is located on the fixed support at one end that extends relative to the traveling wheels, close to or located in the middle of the two traveling wheels.

[0006] In this application, at least two traveling wheels flexibly mounted on a fixed support form a relatively stable structure while ensuring the fixed support can move freely. This ensures that the traveling wheels make matching contact with the track under the gravity of the flipping component, achieving a stable connection between the fixed support and the track. By placing the flipping component at the downward extension end of the fixed support, the space occupied by the flipping component during rotation is reduced, making the entire device structure more compact and improving the vertical space requirement of the flipping mechanism. Placing the flipping component in the middle of the traveling wheels ensures that even when the front traveling wheel along the rotation direction of the flipping component is under pressure during rotation, it can still maintain the stability of rotation and can transmit the pressure to the rear traveling wheel, achieving automatic matching contact between the rear traveling wheel and the track. This ensures that when the fixed support bears the unstable load during the rotation of the flipping component, it can gradually and automatically adapt and adjust the contact with the track, thereby ensuring the stability and reliability of the flipping component during rotation.

[0007] Furthermore, the flipping assembly includes a flipping frame, a support frame, and a rotating assembly, wherein the flipping frame is rotatably connected to the fixed bracket via the rotating assembly; both ends of the support frame are fixed to the flipping frame and are spaced apart along the rotation axis of the flipping frame; the rotating assembly is fixedly mounted on the fixed bracket, and the moving end of the rotating assembly is connected to the flipping frame as a whole.

[0008] Furthermore, the flipping frame is machined with a hollowed-out groove in the middle.

[0009] Furthermore, the support frame includes: a shell, a receiving groove, and a receiving cavity, wherein the shells are connected end to end to form a receiving cavity with a receiving cavity; the inner side of the shell is concave to form a receiving groove.

[0010] Furthermore, it also includes a lifting mechanism and a lifting device connected to the lifting mechanism, wherein the lifting mechanism is embedded and fixed within the receiving cavity and is used to drive the lifting and lowering of the lifting device.

[0011] Furthermore, the shape of the lifting device matches the groove of the tilting frame, and when the lifting device is raised to the upper limit, the lifting device is embedded in the groove.

[0012] Furthermore, the spreader also includes a locking component for locking or releasing the container.

[0013] Furthermore, the spreader also includes an offset component for fine-tuning the position of the spreader.

[0014] The tilting mechanism and container tilting and unloading device provided in the above embodiments have at least the following advantages: 1. By flexibly setting at least two traveling wheels on the fixed support, a relatively stable structure can be formed while ensuring that the fixed support can move freely. Under the gravity of the flipping component, the traveling wheels are ensured to make matching contact with the track, thus realizing a stable connection between the fixed support and the track. By setting the flipping component at the downward extension end of the fixed support, the space occupied by the flipping component during turnover can be reduced, making the entire device structure more compact and improving the vertical space requirement of the flipping mechanism. 2. The tilting and fixing traveling frame of this utility model is arranged on both sides of the tilting frame, without occupying the height space of the tilting system. It also eliminates the need for additional tilting and fixing frames and a traveling trolley system. The lifting system of the spreader is arranged inside the tilting frame, also without occupying height space. This system's arrangement allows for container unloading even when height space is limited. The spreader's lifting system is located inside the tilting frame, and the top of the spreader has a fully open structure, ensuring smooth material flow during unloading. The unloading process will not cause impact damage to the lifting system.

[0015] 3. This utility model places the tilting component in the middle of the traveling wheels, ensuring that even when the front traveling wheel along the rotation direction of the tilting component is under pressure during rotation, it can still maintain the stability of rotation and can transmit pressure to the rear traveling wheel, achieving automatic matching contact between the rear traveling wheel and the track. This ensures that when the fixed support bears the unstable load during the rotation of the tilting component, it can gradually and automatically adjust the contact between itself and the track, thereby ensuring the stability and reliability of the tilting component during rotation. The traveling wheels set on the fixed support form a stable four-point support structure, which can automatically adjust the contact between itself and the track as the center of gravity changes during the rotation of the tilting component, ensuring a smooth and reliable connection between the entire tilting mechanism and the track. The support frames that span across the top of the tilting frame and are spaced apart enhance the installation frame. While maintaining excellent mechanical properties, it can form a stable structure with an internal cavity together with the tilting frame, thereby providing a working space to accommodate containers. When tilting operations are performed, it can provide side support for the spreader. It not only improves the load-bearing capacity of the tilting frame, but also forms an internal cavity with the tilting frame, further improving space utilization and reducing the space requirement in the vertical direction. The cavity formed by the shell can effectively house the lifting mechanism, thereby effectively reducing the space occupation in the vertical direction, improving space utilization, and also providing good protection for the lifting mechanism. The receiving groove formed by the concave bottom of the shell can house the spreader, providing good protection for the spreader and reducing the space requirement in the vertical direction after the spreader clamps the container during operation, further improving the space requirement in the vertical direction during unloading.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be noted that if any directional indication, such as up, down, left, right, front, back, etc., is involved in the embodiments of this utility model, such directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. Furthermore, if any description involving "first," "second," "S1," "S2," "step one," "step two," etc., is involved in the embodiments of this utility model, such description is only for descriptive purposes and should not be construed as indicating or implying their relative importance, or implicitly indicating the number of technical features indicated or the execution order of the method. Those skilled in the art will understand that anything that does not violate the essential points of the utility model within the scope of its inventive concept should be included within the protection scope of this utility model.

[0019] like Figure 1As shown, this utility model provides a flipping mechanism, including: a flipping component 20 and at least one fixed support 10, wherein at least two flexibly connected traveling wheels 11 are provided at the top of the fixed support 10, and the traveling wheels 11 are spaced apart along the direction of travel of the fixed support 10; in one embodiment, the traveling wheels 11 are arranged on both sides of the rotation axis of the flipping component 20 (the axis of the traveling wheels and the rotation axis, the projection of the three forms a triangle, and the traveling wheels are equivalent to being distributed on both sides of the rotation axis), preferably, they are symmetrically arranged along the rotation axis. The flipping component 20 is rotatably arranged at the downward extending end of the fixed support 10, and is close to or located in the middle of the traveling wheels 11; thus, by flexibly setting at least two traveling wheels on the fixed support, a relatively stable structure can be formed while ensuring that the fixed support can move freely, thereby ensuring that the traveling wheels make matching contact with the track under the gravity of the flipping component, and realizing a stable connection between the fixed support and the track; by setting the flipping component at the downward extending end of the fixed support, the space occupied by the flipping component during rotation can be reduced, making the entire device structure more compact and improving the flipping mechanism. The structure addresses the spatial requirements in the vertical direction. By placing the tilting component in the middle of the traveling wheels, it ensures that even when the front traveling wheel along the rotation direction of the tilting component is under pressure during rotation, the component maintains stable rotation and can transfer pressure to the rear traveling wheel. This allows for automatic matching contact between the rear traveling wheel and the track, ensuring that the fixed bracket can gradually and automatically adjust its contact with the track when bearing unstable loads during the rotation of the tilting component. This ensures the stability and reliability of the tilting component during rotation, making it particularly suitable for application scenarios where the center of gravity of the tilting component changes during rotation.

[0020] In this embodiment, the tilting mechanism with this structure always has its center of gravity located between the two traveling wheels, forming a stable triangular structure with the center of gravity of the traveling wheels, resulting in high overall structural stability.

[0021] Preferably, the fixed brackets 10 are in two sets, respectively arranged on the end side of the flipping assembly 20, and the traveling wheels 11 are symmetrically arranged along the rotation axis of the flipping assembly 20; thus, by the traveling wheels symmetrically arranged along the rotation axis of the flipping assembly, a stable four-point support structure is formed, which can automatically adjust the contact with the track as the center of gravity changes during the rotation of the flipping assembly, ensuring a smooth and reliable connection between the entire flipping mechanism and the track.

[0022] Optionally, to achieve fixed operation at a preset workstation on a predetermined track, the traveling wheel 11 is lockable to the track; preferably, to facilitate the adjustment and switching of the entire tilting mechanism's position on the track, a traveling drive component 12 is also included, which is driven and connected to the traveling wheel 11. The fixed end of the traveling drive component 12 is connected to the fixed bracket 10, and the movable end of the traveling drive component 12 is connected to the traveling wheel 11; furthermore, the traveling wheel 11 is lockable to the track; thus, through the driven traveling drive mechanism and the traveling wheel, the position on the beam can be easily adjusted, and through the movable locking of the traveling wheel and the track, the traveling component can be flexibly locked at any position on the track, thereby enabling flexible and precise switching between different container transport tracks.

[0023] Furthermore, the specific structure of the flexible connection between the fixed bracket 10 and the traveling wheel 11 can be a combination connection between a shaft and a bearing, or a connection between elastic elements, such as springs or rubber. It only needs to satisfy the requirement that the structure between the fixed bracket and the traveling wheel has a buffering function. The specific structure, principle, or other structural shapes that achieve the same function for the flexible connection should be easily conceived by those skilled in the art, and therefore will not be elaborated upon here. In summary, the flipping mechanism provided by this utility model, through at least two traveling wheels flexibly mounted on a fixed support, can form a relatively stable structure while ensuring the free movement of the fixed support. This ensures that, under the gravity of the flipping component, the traveling wheels maintain a matching contact with the track, achieving a stable connection between the fixed support and the track. By placing the flipping component at the downward extension end of the fixed support, the space occupied by the flipping component during rotation is reduced, making the entire device structure more compact and improving the vertical space requirements of the flipping mechanism. Placing the flipping component in the middle of the traveling wheels ensures that the flipping component rotates along the axis of rotation during its rotation. Even under pressure, the front-side traveling wheel of the turning component can maintain stable rotation and transmit the pressure to the rear-side traveling wheel, achieving automatic matching contact between the rear-side traveling wheel and the track. This ensures that when the fixed support bears unstable loads during the rotation of the tilting component, it can gradually and automatically adjust the contact between itself and the track, thereby ensuring the stability and reliability of the tilting component during rotation. The traveling wheels set on the fixed support form a stable four-point support structure, which can automatically adjust the contact between itself and the track as the center of gravity changes during the rotation of the tilting component, ensuring a smooth and reliable connection between the entire tilting mechanism and the track.

[0024] Optionally, such as Figure 2 and Figure 3As shown, the flipping assembly 20 includes a flipping frame 21, at least one support frame 22, and at least one rotating assembly 23. The flipping frame 21 is rotatably connected to the fixed support 10 via the rotating assembly 23. The support frame 22 has an overall arched shape and is arranged across the short side of the flipping frame 21. Its two ends are fixed to the top surface of the long side of the flipping frame 21 and extend at intervals along the length of the flipping frame 21. The fixed end of the rotating assembly 23 is fixed to the fixed support 10 and is located away from the beam 300. The moving end of the rotating assembly 23 is connected to the flipping frame 21 as a whole and moves together with it. Thus, the flipping frame is rotatable between the fixed supports via the rotating assembly. By placing the rotating assembly at the end away from the beam, the space occupied in the vertical direction is effectively reduced, while the reliability and stability of the entire flipping mechanism are improved.

[0025] Preferably, the support frames 22 are in two sets, spaced apart along the length of the tilting frame 21. Preferably, in order to effectively protect the lifting mechanism during unloading and prevent impact damage to the lifting mechanism during unloading, the tilting frame 21 is machined with a hollow rectangular groove in the middle. Thus, through the rectangular groove in the middle of the tilting frame, when the spreader is raised to the upper limit, the spreader is stuck inside the rectangular groove of the tilting frame. During the tilting operation, the rectangular groove can provide good side support for the spreader, improving the reliability and safety of the operation. By using the support frames that span the top of the tilting frame and are spaced apart, the connecting rods between the support frames are removed, increasing the internal storage space while also having excellent mechanical properties. Together with the tilting frame, they can form a stable structure with an internal cavity, thereby providing a working space to accommodate containers. When the tilting operation is performed, it can provide side support for the spreader. This improves the load-bearing capacity of the tilting frame and also forms an internal storage cavity with the tilting frame, further improving the space utilization and compressing the space requirements in the vertical direction. Optionally, the support frame 22 is formed by connecting panels and rods. Specifically, the support frame 22 includes: a shell 221, a receiving groove 222, and a receiving cavity 223. The shells 221 are connected end to end, forming a receiving cavity 223 with a receiving cavity. The inner side of the shell 221 is concave, forming a receiving groove 222 with an opening facing downwards. Thus, the receiving cavity formed by the shell effectively houses the lifting mechanism, thereby effectively reducing the space occupied in the vertical direction, improving space utilization, and providing good protection for the lifting mechanism. The receiving groove formed by the concave bottom of the shell can house the spreader, providing good protection for the spreader, while reducing the space requirement in the vertical direction after the spreader clamps the container during operation, further improving the space requirement in the vertical direction during unloading.

[0026] Furthermore, the rotary component 23 can be a gear transmission assembly or a combination of a motor and gears; here, it only needs to satisfy the motion drive to achieve rotation. The specific structure, principle, or other structural shapes that achieve the same function of the rotary component should be readily conceived by those skilled in the art, and therefore will not be elaborated upon here.

[0027] The aforementioned tilting mechanism also includes a lifting mechanism 30 and a spreader 40. The spreader is used to lift the container. One end of the lifting mechanism 30 is embedded and fixed in the cavity (accommodation cavity 223) of the tilting component 20, and the other end is connected to the spreader. When the lifting mechanism is driven by its drive structure, it drives the spreader to move up and down, thereby completing the lifting of the container by the spreader. In this embodiment, by embedding the lifting mechanism inside the tilting mechanism, strength is ensured while effectively reducing the space occupied, especially the vertical space. This makes it possible to unload containers in situations where height space is limited, significantly expanding the application range of the container tilting and unloading device. At the same time, due to the embedded structure of the lifting mechanism, the impact of materials on various components of the lifting mechanism during unloading is effectively reduced, providing good protection. By using a spreader to grab and fix the container, it is well compatible with both open wagon-borne container transshipment and rail flatbed-borne container transport.

[0028] Preferably, the spreader 40 and the tilting assembly 20 are releasably locked together, thereby ensuring that the spreader can reliably rotate with the tilting mechanism after the container is lifted, thus ensuring the reliability and safety of the unloading process.

[0029] In summary, the tilting mechanism provided in this application, through the support frames that span above the tilting frame and are spaced apart, enhances the mechanical performance of the mounting frame while forming a stable structure with an internal cavity together with the tilting frame. This provides a working space to accommodate containers and provides side support for the spreader during tilting operations. It also improves the load-bearing capacity of the tilting frame and, together with the tilting frame, forms an internal cavity, further improving space utilization and reducing vertical space requirements. The cavity formed by the shell effectively houses the lifting mechanism, thereby reducing vertical space occupation and improving space utilization while providing good protection for the lifting mechanism. The recessed receiving groove at the bottom of the shell houses the spreader, providing good protection for it and reducing vertical space requirements after the spreader clamps the container during operation, further improving vertical space requirements during unloading.

[0030] In a preferred embodiment of this utility model, a container tipping and unloading device is also provided. This device, through the reciprocating movement of a tipping mechanism on the beam 300, transfers the materials loaded in the container 100 to the transfer device 200. It is suitable for existing open wagon-mounted container transport methods and is also compatible with flatbed rail transport methods, effectively solving the problem that existing container unloading devices occupy a large vertical space and have limited application scenarios.

[0031] Optionally, the spreader includes a gantry and at least one locking component. The gantry is a rectangular frame formed by connecting panels and rods. The fixed end of the locking component is disposed on the gantry, and the movable end of the locking component is releasably locked to a flipping component. Thus, the gantry and support frame can be easily locked together via the locking component, allowing them to be connected as a single unit with the fixed support and move together. Specifically, the locking component includes a locking member and a locking drive member. The locking drive member fixes the gantry, one end of the locking member is connected to the locking drive member, and the other end extends away from the locking drive member. A container locking device is installed inside the container spreader for gripping containers.

[0032] In a preferred embodiment of this application, the locking component is adapted to the housing of the support frame. For example, the housing is machined with holes, and the locking member of the locking component is driven by the locking drive member to be embedded in the corresponding hole in the housing, thereby realizing the locking of the hanger and the support frame.

[0033] Optionally, to improve operational efficiency, the spreader also includes at least one offset component disposed between the lifting frame and the tilting assembly. One end of the offset component is fixed to the tilting assembly, and the other end, oppositely disposed, is drivably connected to the lifting frame. Thus, by using the offset drive component, the relative position of the tilting mechanism and the offset support can be adjusted, thereby adjusting the position between the offset support and the offset base. This achieves a change in the position of the lifting frame, and consequently, an adjustment of the spreader's position. When the container's placement position deviates, it can be offset as needed, facilitating container grabbing and significantly improving operational efficiency.

[0034] In summary, the spreader provided in this application, through the locking component, allows for extremely convenient locking of the spreader and support frame, which can then be connected to the tilting mechanism to form a unified movement. The offset drive component allows adjustment of the relative position between the tilting mechanism and the offset support, thereby adjusting the position between the offset support and the offset base, thus changing the position of the spreader and consequently adjusting the position of the spreader. When the container's placement position deviates, it can be offset as needed, facilitating container grabbing and significantly improving operational efficiency.

[0035] Below, in conjunction with the appendix Figure 4This invention describes the workflow of the unloading system provided in a specific embodiment of the present invention.

[0036] The container 100 loaded with materials moves along the track and enters the unloading station. The traveling wheels 11, driven by the traveling drive component 12, move to above the container 100 that needs to be unloaded. The drive component of the lifting mechanism 30 controls the traction rope to make the spreader 40 connected to it begin to descend vertically until the spreader's frame is completely aligned with the container 100 to be unloaded and locked, thus completing the grabbing of the container 100 to be unloaded. Driven by the drive assembly, the traction rope lifts the container 100 to be unloaded to the tilting frame 21 via the spreader, and locks the spreader and support frame 22 by the locking assembly. At this time, under the action of the travel drive 12, the tilting frame 21 and the support frame 22 are driven to move together along the crossbeam of the beam frame 300 until they are directly above the transfer device 200. The slewing assembly 23 drives the tilting frame 21 to tilt the container 100 to be unloaded, and the material in the container 100 is unloaded. After the unloading is completed, the tilting frame 21 is driven by the slewing assembly 23 to rotate back to the initial angle and complete the reset. At the same time, driven by the travel drive 12, it moves along the crossbeam of the beam frame 300 to directly above the unloading position. Under the joint action of the lifting mechanism 30 and the spreader 40, the empty container 100 is returned to its original position, completing the unloading operation of the entire loaded container 100. The entire operation requires no additional space, is efficient and requires minimal operating space; it can also automatically and accurately align itself, optimizing the steps of container unloading operations, and is compatible with unloading operations of different container transport modes, thereby improving the overall efficiency of container unloading operations and enhancing the capacity of the unloading platform.

[0037] The container tipping and unloading device provided in the above embodiments of this application has at least the following characteristics: By flexibly mounting at least two traveling wheels on the fixed support, a relatively stable structure can be formed while ensuring the free movement of the fixed support. This ensures that under the gravity of the tilting component, the traveling wheels maintain a matching contact with the track, achieving a stable connection between the fixed support and the track. By placing the tilting component at the downward extension of the fixed support, the space occupied by the tilting component during rotation is reduced, making the entire device structure more compact and improving the vertical space requirements of the tilting mechanism. Placing the tilting component in the middle of the traveling wheels ensures that even when the front traveling wheel along the rotation direction of the tilting component is under pressure, it maintains rotational stability and can transmit pressure to the rear traveling wheel, achieving automatic matching contact between the rear traveling wheel and the track. This ensures that when the fixed support bears unstable loads during the rotation of the tilting component, it can gradually and automatically adapt and adjust its contact with the track, thus ensuring the stability and reliability of the tilting component during rotation. The traveling wheels mounted on the fixed support form a stable four-point support structure, enabling… During the turnover of the tilting component, the contact with the track is automatically adjusted according to the change of the center of gravity, ensuring a smooth and reliable connection between the entire tilting mechanism and the track. Support frames, spaced apart and spanning above the tilting frame, enhance the mechanical performance of the mounting frame and together with the tilting frame, form a stable structure with an internal cavity, providing a working space to accommodate containers. During tilting operations, they provide side support for the spreader. This increases the load-bearing capacity of the tilting frame and, together with the tilting frame, forms an internal cavity, further improving space utilization and reducing vertical space requirements. The cavity formed by the shell effectively houses the lifting mechanism, thereby reducing vertical space occupation, improving space utilization, and providing good protection for the lifting mechanism. The recessed groove at the bottom of the shell houses the spreader, providing good protection for it and reducing vertical space requirements after the spreader clamps the container during operation, further improving vertical space requirements during unloading.

[0038] Furthermore, the driving components in this application can be precisely controllable telescopic driving parts such as hydraulic cylinders, pneumatic cylinders, or combinations of hydraulic and pneumatic cylinders, or other driving methods. For example, the use of electric motors or other driving structures should be readily conceived by those skilled in the art, and therefore will not be elaborated upon here.

[0039] Furthermore, the locking mechanism in this application can be achieved through a specific transmission ratio between gears, or through a solenoid valve or other means. The specific structure of the locking mechanism should be easily conceived by those skilled in the art, so it will not be described in detail here.

[0040] Furthermore, this application may also involve a system control section, which can be used to control the starting and stopping of the motor, the extension and retraction of the hydraulic cylinder, and the closing of the electric cylinder, etc. The configuration of the control system is well known to those skilled in the art and will not be described in detail here.

[0041] The above description is merely a specific embodiment of this utility model. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should all be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
