Description

Technical Field

[0001] The present invention relates to the technical field of container tipping and unloading, and in particular to a container tipping and unloading system. Background Art

[0002] With the advancement of industrial automation and clean production, metallurgical companies are increasingly demanding automated, ultra-low-emission, and standardized production equipment. Containerized transportation of raw materials has become a new loading and transportation method for steel companies in recent years. Containerized transportation reduces breakage and dust during loading, unloading, and transshipment, and its standardized dimensions facilitate the coordination of upstream and downstream equipment in the production process.

[0003] At present, various raw materials in the metallurgical industry, such as coke, mineral powder and other raw materials, are generally shipped in open-top containers that are easy to load and unload. Open-top containers are open containers that do not have a steel top compared to conventional containers, making it easier to load materials. When unloading an open container, it is generally necessary to use a container tipping system. Patent application number 201510480061.7 discloses a material tipping device for an open-top container, which uses a mechanism similar to a railway tipping machine and is equipped with two large end plates and large and small gear transmission devices. The large and small gear transmission devices drive the end plates to rotate, thereby driving the container on the movable platform to flip, thereby realizing the unloading of the container. In actual use, the above-mentioned platform-tumbling container tipping system still has many defects:

[0004] First, the end plate is large, the equipment is heavy, and the investment is high;

[0005] Secondly, the large and small gear transmission devices are exposed, which makes it easy for foreign objects to be entangled. In addition, the maintenance work is very demanding in dusty working environments.

[0006] Third, the container's anti-overturning mechanism is relatively complex, requiring high investment and maintenance. The springs are prone to aging, and each time the container is turned over or unloaded, it will collide, resulting in a short service life of the container.

[0007] Fourth, the dust removal system is not easy to set up.

[0008] In view of this, the inventor has designed a container tipping system based on many years of production design experience in this field and related fields and after repeated experiments, in order to solve the problems existing in the prior art. Summary of the Invention

[0009] The object of the present invention is to provide a container tipping system capable of automatically, efficiently and reliably unloading bulk materials in an open-top container.

[0010] To achieve the above-mentioned object, the present invention provides a container tipping system, wherein the container tipping system comprises:

[0011] A fixed base having two fixed platforms spaced apart, a buffer silo fixed between the two fixed platforms, and an open top of the buffer silo;

[0012] A box turning frame is arranged above the buffer silo, the box turning frame includes a box turning platform and two end frames, the two end frames are rotatably mounted on the top of the two fixed platforms, two opposite sides of the box turning platform are fixedly connected to the two end frames, and the box turning platform has an installation position for installing a container;

[0013] Two driving mechanisms are respectively arranged on the two fixed platforms, the driving mechanisms are connected to the end frames and drive the box turning platform to turn over through the end frames;

[0014] The container turning platform is provided with an arm device and multiple locking mechanisms, and the locking mechanism can fix the container at the installation position. The arm device is provided on the side of the container turning frame that is flipped downward. The arm device has a working position and a released position. The arm device is against the container in the working position, and the arm device is away from the container in the released position.

[0015] Compared with the prior art, the present invention has the following characteristics and advantages:

[0016] The container tipping system proposed in the present invention fixes the container on the tipping platform by means of an arm device and a locking mechanism, and the driving mechanism drives the tipping platform to flip through the end frame. The container fixed on the tipping platform by the arm device and the locking mechanism flips along with the tipping platform, thereby being able to quickly flip the container from a horizontal state to an inclined or inverted state, thereby facilitating rapid and complete unloading of the goods.

[0017] The container tipping system proposed in the present invention enables the container to be flipped 180 degrees along with the container tipping platform, realizing unloading from the top of the container, eliminating manual operation of opening and closing the container door, facilitating unmanned production and improving production efficiency.

[0018] The container tipping system proposed by the present invention has a simple structure, a compact design, and tight and stable connections between various components, thereby facilitating daily maintenance and upkeep.

[0051] The details of the present invention can be more clearly understood by referring to the accompanying drawings and the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are only for the purpose of explaining the present invention and are not to be construed as limiting the present invention in any way. Based on the teachings of the present invention, a skilled person can conceive of any possible variations based on the present invention, and such variations should be considered to fall within the scope of the present invention.

[0052] like Figures 1 to 9 As shown, the present invention provides a container unloading system 100, which includes:

[0053] The fixed base 10 has two fixed platforms 11 spaced apart from each other, and a buffer silo 20 is fixed between the two fixed platforms 11. The top of the buffer silo 20 is open.

[0054] The tumbler rack 30 is disposed above the buffer silo 20 and includes a tumbler platform 31 and two end frames 32. The two end frames 32 are rotatably mounted on top of the two fixed platforms 11. The two opposite sides of the tumbler platform 31 are fixedly connected to the two end frames 32. The tumbler platform 31 has an installation position 311 for installing the container 200.

[0055] Two driving mechanisms 40 are respectively provided on the two fixed platforms 11. The driving mechanisms 40 are connected to the end frames 32 and drive the box turning platform 31 to turn over through the end frames 32.

[0056] The tumbling platform 31 is provided with an arm device 33 and a plurality of locking mechanisms 34. The locking mechanism 34 can fix the container 200 at the installation position 311. The arm device 33 is provided on the side of the tumbling platform 31 that is flipped downward. The arm device 33 has a working position and a released position. The arm device 33 is against the container 200 in the working position, and the arm device 33 is away from the container 200 in the released position.

[0057] The container tipping system 100 proposed in the present invention fixes the container 200 on the tumbling platform 31 by means of an arm device 33 and a locking mechanism 34. The driving mechanism 40 drives the tumbling platform 31 to flip through the end frame 32. The container 200 fixed to the tumbling platform 31 by the arm device 33 and the locking mechanism 34 flips along with the tumbling platform 31, thereby being able to quickly flip the container 200 from a horizontal state to an inclined or inverted state, thereby facilitating rapid and complete unloading of the cargo.

[0058] In the container tipping system 100 proposed by the present invention, the arm assembly 33 is located on the side where the tipping platform 31 and container 200 are tilted downward. This arm assembly not only secures the container 200 but also provides additional support during the downward tilt of the tipping platform 31, preventing the container 200 from suddenly sliding due to gravity. This enhances operational safety and effectively prevents deformation of the container 200, thereby ensuring the service life of the container 200. Furthermore, the arm assembly 33's ability to support the container 200 also ensures that the locking mechanism 34 is not subjected to excessive shear forces, thereby extending the service life of the locking mechanism.

[0059] The container tipping system 100 proposed in the present invention enables the container 200 to be flipped 180° along with the container tipping platform 31, realizing unloading from the top of the container 200, eliminating manual operation of opening and closing the container door, facilitating unmanned production and improving production efficiency.

[0060] The container dumping system 100 proposed by the present invention has a simple structure, a compact design, and tight and stable connections between various components, thereby facilitating daily maintenance and upkeep.

[0061] The container dumping system 100 proposed by the present invention has good dust removal conditions, can realize large-scale production, and solve the problem of bulk material unloading in million-ton-level factories.

[0062] In an optional embodiment of the present invention, the container turning platform 31 is provided with an arm device 33 and four locking mechanisms 34 . The four locking mechanisms 34 are respectively provided at the four top corners of the container 200 to fix the container 200 at the installation position 311 .

[0063] In an optional embodiment of the present invention, Figure 5 、 Figure 6 As shown, the arm assembly 33 includes a container-blocking bar 331 and two push rod mechanisms 332, each secured to one end frame 32. The container-blocking bar 331 is positioned parallel to the container-turning platform 31, and its ends are connected to the two push rod mechanisms 332. The push rod mechanisms 332 propel the container-blocking bar 331 back and forth between a working position and a released position. With this structure, the container-blocking bar 331 has a released position and a working position. When the container 200 needs to be lifted or lowered, the container-blocking bar 331 is placed in the released position to facilitate movement of the container 200.

[0064] In an optional example of this embodiment, a buffer component may be provided at the portion of the container-blocking bar 331 that contacts the container 200 , and the buffer component is used to ensure that the container-blocking bar 331 and the container 200 do not come into hard contact.

[0065] Preferably, the buffer component can be a buffer component made of flexible materials such as rubber strips, nylon tapes, nylon plates, etc.

[0066] In an optional example of this embodiment, the push rod mechanism 332 is a hydraulic push rod, which is a retractable push rod driven by a hydraulic station. The hydraulic push rod drives the box blocking bar 331 away from the container 200 and closer to the container 200 by the extension and retraction of the hydraulic push rod.

[0067] Furthermore, the two hydraulic push rods mentioned above use the same hydraulic station, with one station having two cylinders and a synchronization valve to ensure that the two hydraulic push rods can move synchronously.

[0068] In an optional example, the hydraulic push rod is provided with a proximity switch to ensure accurate positioning of the box blocking rod 331 at its release position and working position.

[0069] In an optional example of this embodiment, the container guardrail 331 is a steel frame structure to ensure its supporting strength for the container 200 .

[0070] In an optional example of this embodiment, the arm support device 33 further includes at least one support swing rod 333, one end of which is hinged to the box turning platform 31, and the other end of which is hinged to the box blocking rod 331. The support swing rod 333 can provide auxiliary support for the box blocking rod 331, further ensuring that the box blocking rod 331 can operate stably and reliably.

[0071] In an optional example, the arm support device 33 has two support swing rods 333 , and the two support swing rods 333 are respectively located at two ends of the box blocking rod 331 .

[0072] In one alternative embodiment, the support rocker 333 and the box-blocking bar 331 are hingedly connected by a hinge assembly. A slot is defined at the other end of the support rocker 333, and the hinge assembly is movably disposed within the slot. With this structure, when the box-blocking bar 331 is moved between the released position and the operating position by the hydraulic push rod, the height of the box-blocking bar 331 remains consistent, protecting the hydraulic push rod from shear forces and damage.

[0073] In an optional example, the push rod mechanism 332 (hydraulic push rod) is connected to the end frame 32 through a hinge structure, and the movable setting of the push rod mechanism 332 (hydraulic push rod) is realized by relying on the hinge structure between the support rocker arm 333 and the box turning platform 31, and the hinge structure between the push rod mechanism 332 and the end frame 32.

[0074] In an optional embodiment of the present invention, the container tipping system 100 further includes a dust hood 50. The dust hood 50 is located near the downwardly tilted side of the container tipping platform 31 and outside the tipping trajectory A of the container 200 and the tipping trajectory B of the container tipping platform 31. The dust hood 50 is fixedly connected to the top of the buffer silo 20. The dust hood 50 effectively prevents dust and particulate matter that may be generated during the tipping process from escaping into the external environment, thereby protecting the working environment and reducing air pollution.

[0075] In an optional example of this embodiment, the dust hood 50 is a hood body with the top, sides and back all closed, leaving only one side open for lifting the container 200. When the container 200 is flipped over, the unloading range of the container 200 can be completely wrapped in the dust hood 50, which is beneficial to improving the dust removal effect.

[0076] Furthermore, the dust hood 50 is equipped with a soft rubber curtain on the side facing the container 200, making it particularly suitable for unloading dusty dry materials such as CDQ coke. When the container 200 is turned over, dust emission points face the back and top surfaces of the dust hood 50. The rubber curtain blocks any excess dust, reducing air leakage and effectively suppressing dust spillage.

[0077] Furthermore, the dust removal hood 50 is externally connected to a dust removal device 90, which includes a dust removal pipe and a dust collector arranged on the dust removal pipe. Dust generated when the container 200 is flipped can be sucked away by the dust removal pipe in time, further improving the dust removal effect.

[0078] In an optional embodiment of the present invention, a bearing block 12 is mounted on top of each fixed platform 11 for mounting an end frame 32. A main support shaft 35 is rotatably mounted within the bearing block 12. One end of the main support shaft 35 is fixedly connected to the end frame 32, and the other end of the main support shaft 35 is connected to the drive mechanism 40. With this structure, the main support shaft 35 and the bearing block 12 support the container tipping frame 30, transferring the primary load generated by the container 200 to the fixed platforms 11 at each end of the container tipping frame 30.

[0079] In an optional example of this embodiment, Figure 3 、 Figure 11 As shown, the drive mechanism 40 includes a base 41, a gear 42, a rack 43, and a hydraulic push rod 44. The base 41 is fixed to the fixed platform 11 and is provided with a guide rail. The rack 43 is movably mounted on the guide rail. The hydraulic push rod 44 is connected to the rack 43 and can move the rack 43. The gear 42 is fixedly mounted outside the main support shaft 35 and meshes with the rack 43. With this structure, when the hydraulic push rod 44 pushes the rack 43 to move, the gear 42 meshing with the rack 43 also rotates, which in turn drives the main support shaft 35 and ultimately causes the box turning frame 30 to flip. Because the drive mechanism 40 uses a gear and rack combination, the weight of the equipment is reduced, which reduces investment and maintenance requirements.

[0080] Furthermore, the hydraulic push rods 44 of the two driving mechanisms 40 also use a hydraulic station 45, one station with two cylinders and a synchronization valve to ensure that the hydraulic push rods 44 on both sides move synchronously, so that the two ends of the box turning frame 30 are evenly stressed.

[0081] In an optional example, the rack 43 is driven to move back and forth along the guide rail by the extension and contraction of the hydraulic push rod 44, and then the box turning frame 30 is driven to turn over within the range of 0° to 180° through the gear 42 and the main support shaft 35.

[0082] Furthermore, a proximity switch is also provided on the hydraulic push rod 44 to ensure that the box turning rack 30 is positioned at two positions of 0° and 180°.

[0083] In another optional example of this embodiment, Figure 4 As shown, the driving mechanism 40 includes a multi-stage motor and a high-speed ratio reducer, and the multi-stage motor and the high-speed ratio reducer directly drive the main support shaft 35 to rotate.

[0084] In an optional embodiment of the present invention, the axis of the main support shaft 35 passes through the center of gravity of the container 200 to ensure low energy consumption and stable operation of the equipment when the container turning frame 30 is turned over.

[0085] In an optional embodiment of the present invention, Figure 1 As shown, the locking mechanism 34 includes a twist lock 341 and an electric actuator 342. A lock hole is provided on the bottom of the container 200 to align with the twist lock 341. After the container 200 is placed on the container turning platform 31, the lock hole is aligned with the twist lock 341, and the electric actuator 342 automatically rotates the twist lock, thereby locking the container 200 on the container turning platform 31, realizing unmanned production.

[0086] In an optional embodiment of the present invention, the container tipping system 100 further includes a drag chain mechanism 80, which is used to install cables, hydraulic pipes and other pipelines from the fixed platform 11 to the container tipping rack 30 to ensure that the cables, hydraulic pipes and other pipelines can be used normally when the container tipping rack 30 is flipped.

[0087] In an optional embodiment of the present invention, Figure 7 As shown, the installation position 311 is rectangular and has four corners. A container guide device 36 is provided at each corner of the installation position 311. The guide device 36 facilitates the container 200 to quickly and accurately align the lock hole with the twist lock 341 when the container 200 is placed on the container turning platform 31.

[0088] In an optional example of this embodiment, the guide device 36 is a railing with a large upper end and a contracted lower end, which is made of a steel plate bent 90° to ensure rapid positioning of the container 200.

[0089] In an optional embodiment of the present invention, diagonal braces can be added to the turning platform 31 and the end frame 32 of the turning frame 30 according to length requirements to enhance the overall stability of the turning frame 30.

[0090] In an optional embodiment of the present invention, Figure 9 As shown, the container tipping system 100 further includes a lifting device 60 , which is located above the container tipping rack 30 and is used to lift the container 200 onto the container tipping platform 31 .

[0091] In an optional example of this embodiment, the lifting device 60 can be adapted to containers 203 transported by road, containers 202 transported by rail, and containers 203 transported by water.

[0092] In an optional example of this embodiment, the lifting device 60 can be a rail-mounted container gantry crane, a shore-side quay crane, or a container bridge crane located in a factory building.

[0093] Specifically, the rail-mounted container gantry crane can adapt to the above three modes of container transportation at the same time; the gantry crane is located on land, and the cantilevered part can lift containers shipped by ships; the lower part of the gantry crane can lift containers from roads and railways, and it also has a storage and turnover area for empty containers.

[0094] Furthermore, in order to match the position of the dust hood 50 and its dust removal pipe, when the lifting device 60 adopts a gantry crane, the gantry crane can also adopt high and low rails, with a trestle column under the high rail, and the dust removal pipe passes through the trestle column to connect to the dust hood 50.

[0095] In an optional embodiment of the present invention, a discharging device 70 is provided at the bottom of the buffer silo 20, and the material in the buffer silo 20 can be transported to the belt conveyor through the discharging device 70, thereby realizing the mechanization and automation of the discharging of the buffer silo 20.

[0096] In an optional example of this embodiment, the discharging device 70 can be a vibration discharging machine or a belt discharging machine.

[0097] In an optional example of this embodiment, the buffer silo 20 can accommodate at least one container of materials.

[0098] In an optional embodiment of the present invention, an empty container turnover site 300 is provided below the container unloading system 100 to facilitate continuous unloading of multiple containers 200 .

[0099] In an optional embodiment of the present invention, multiple container dumping systems 100 may be connected in series, which can not only improve the dumping capacity, but also improve the output capacity of the belt conveyor to achieve large-volume output.

[0100] In another optional embodiment of the present invention, multiple container dumping systems 100 may be connected in parallel to achieve multi-channel output.

[0101] In an optional embodiment of the present invention, the specifications of the container turning platform 31 or the specifications of the installation position 311 on the container turning platform 31 can be changed according to the different sizes of the container 200, so as to be able to adapt to different container models such as 20-foot containers, 40-foot standard containers, 40-foot high containers, 45-foot containers, etc.

[0102] Please refer to Figure 9 、 Figure 10Now, the specific implementation process of the container dumping system 100 proposed by the present invention will be described in detail with reference to an embodiment.

[0103] After being hoisted by the lifting device 60 (crane), the container 200 is placed on the tumbler platform 31. The guide device 36 on the tumbler platform 31 helps the container 200 quickly fall into the installation position 311 and quickly positions the locking hole of the container 200 with the twist lock 341. Then, the electric actuator 342 drives the twist lock 341 to rotate 90 degrees, locking the container 200 on the tumbler platform 31. The sling on the lifting device 60 releases the twist lock, and the lifting hook of the lifting device 60 leaves the tumbler frame 30 area. The hydraulic push rod on the side of the tumbler frame 30 is actuated, pressing the container stop 331 against the side of the container 200, and the tumbler frame 30 is now ready for unloading.

[0104] During unloading, the hydraulic push rod 44 of the drive mechanism 40 is activated, pushing the rack 43 outward. The rack 43 then rotates the gear 42, achieving a 180° flip of the container 200. It should be noted that to improve production efficiency, for dry materials or materials that are easy to unload, the proximity switch position can be adjusted so that the container unloading platform 31 can be completely unloaded by tilting it to 150°. This can shorten the unloading time per container and improve unloading efficiency.

[0105] As container 200 is tipped, the dust removal device on the side of dust hood 50 activates to prevent dust from escaping during tipping. Once the buffer silo 20 beneath the tipping frame 30 is filled with material, the discharge device 70 (feeder) below it begins evenly feeding material to the belt conveyor. To ensure continuous production, the capacity of the discharge device 70 must match the tipping speed of the tipping frame 30. Specifically, the time it takes to discharge a container must be equal to or greater than the time it takes to tip a container.

[0106] After the container 200 is unloaded, the hydraulic push rod 44 retracts the rack 43, which in turn rotates the gear 42, returning the container 200 to its normal position. The twist lock 341 on the container tipping platform 31 can now be opened, and the barrier bar 331 can be released from the side. The lifting device 60 then returns to the top of the container tipping frame 30, securing the empty container 200. The empty container 200 can then be placed in a buffer area on the ground, or directly transported to an empty ship, truck, or train.

[0107] The container dumping system 100 proposed in the present invention can automatically, efficiently and reliably unload bulk materials from an open-top container 200, thereby enabling large-scale production and solving the bulk material unloading problem in million-ton factories.

[0108] The container tipping system 100 proposed by the present invention requires minimal civil engineering work and requires no underground construction, making it suitable for construction in a variety of geological conditions and having a wide range of applications. Furthermore, the container tipping system 100 proposed by the present invention features a simple structure, easy maintenance, and low investment. Furthermore, the container tipping system 100 can also solve the problem of tipping containers transported by multimodal transport, such as water, road, and rail.

[0109] The detailed explanations of the above-mentioned embodiments are intended only to explain the present invention so as to facilitate a better understanding of the present invention. However, these descriptions cannot be interpreted as limiting the present invention for any reason. In particular, the various features described in different embodiments may also be arbitrarily combined with each other to form other embodiments.
