Description

Technical Field

[0001] This invention relates to the field of container manufacturing, and in particular to a special container roof platform. Background Technology

[0002] Standard container production lines have dedicated top-covering platforms. Due to the low production volume of specialty containers, dedicated top-covering platforms are generally not used. However, as the production volume of specialty containers increases, and specialty container production lines become longer with higher compatibility requirements, dedicated tooling stations for top-covering are also needed. Specialty containers come in a wide variety of types with inconsistent length, width, and height dimensions, so the top-covering platforms must be highly compatible.

[0003] The standard container production line's top plate mounting platform lacks flexibility. Due to the low production volume of special containers, top plates are typically mounted on the final assembly table. The final assembly table is responsible for installing the underframe, front frame, rear frame, and left and right side plates, resulting in a large workload and low efficiency. While the final assembly table has many positioning and clamping devices, it lacks top plate positioning fixtures; the top plates are placed relatively far from the final assembly table, requiring the overhead crane to travel a long distance, making the crane very busy. Therefore, separating the top plate mounting process would reduce the workload of the final assembly table, improving its efficiency and also enhancing the efficiency of the welding line. The final assembly table lacks dedicated left and right side plate positioning devices, requiring workers to manually mark lines for alignment, resulting in low accuracy and efficiency. Summary of the Invention

[0004] To address at least one technical problem of the prior art, the present invention provides a special container roofing platform.

[0005] The special container roof platform includes: a lifting frame; a lifting device mounted on the lifting frame for lifting the roof panel; a first positioning frame including a liftable first crossbeam extending in a first direction, the first crossbeam having a pair of positioning blocks whose positions are adjustable in the first direction; a second positioning frame having the first positioning frame, a pair of first legs, and a pair of second legs sequentially arranged in a second direction perpendicular to the first direction, the second positioning frame being selectively and detachably mounted on one of the pair of first legs and the pair of second legs, the second positioning frame including a liftable second crossbeam extending in the first direction, the second crossbeam having a pair of positioning blocks whose positions are adjustable in the first direction; and a pair of positioning beams extending in the second direction, each positioning beam connecting the first crossbeam and the second crossbeam and being positionally adjustable in the first direction, each positioning beam having at least two inwardly extending templates.

[0006] In some embodiments, the top of the hanger is provided with three load-bearing beams that extend outward along a first direction and are spaced apart in a second direction, and each load-bearing beam is provided with a lifting device.

[0008] In some embodiments, the first lifting device and the second lifting device are respectively turbine screw jacks.

[0009] In some embodiments, the first crossbeam and the second crossbeam are respectively provided with waist-shaped holes extending in a first direction, and the positioning block is detachably installed at the waist-shaped holes.

[0010] In some embodiments, each positioning block includes an upper positioning block and a side positioning block, wherein the side positioning block extends along a second direction and is disposed on the side edge of the bottom surface of the upper positioning block, away from another positioning block on the same crossbeam.

[0011] In some implementations, a hydraulic lift is also provided below the gantry.

[0012] In some implementations, one end of the template is rotatably connected to the positioning beam, and the template can be rotated upward about a pivot axis parallel to the second direction.

[0013] In some embodiments, the first positioning frame and the second positioning frame are respectively provided with walking platforms extending along the first direction on both sides.

[0014] In some implementations, an extension platform that extends inward toward the hanger is also housed below the walking platform.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] According to one embodiment of this disclosure, please refer to Figure 1 The special container roof platform includes a lifting frame 1, a lifting device (not shown in the figure), a first positioning frame 3, a second positioning frame 4, and a pair of positioning beams 5. The lifting device is mounted on the lifting frame 1 and is used to lift the roof panel. Please refer to [reference needed]. Figure 3 The first positioning frame 3 includes a liftable first crossbeam 31 extending along a first direction D1, on which a pair of positioning blocks 32 are provided that are adjustable in position along the first direction D1. Please refer to... Figure 1 and Figure 5 A first positioning frame 3, a first support leg 42, and a second support leg 43 are sequentially arranged on a second direction D2 perpendicular to the first direction D1. The second positioning frame 4 is selectively and detachably mounted on one of the first support leg 42 and the second support leg 43. Please refer to [reference needed]. Figure 4 The second positioning frame 4 includes a liftable second crossbeam 41 extending along the first direction D1, and a pair of positioning blocks 32 whose positions are adjustable along the first direction D1 are provided on the second crossbeam 41. Positioning beams 5 on both sides extend along the second direction D2 respectively, and each positioning beam 5 is connected to the first crossbeam 31 and the second crossbeam 41 and is adjustable in position along the first direction D1. Each positioning beam 5 is provided with at least two inwardly extending templates 51.

[0027] Please refer to Figure 6The container is positioned under two positioning frames, and the top plate 63 is transferred from the top plate storage platform 9 next to the lifting frame 1 to the top of the container using a lifting device. The top plate platform of this disclosure can use the four corner pieces 61 of the container top as positioning references. Before moving the container under the two positioning frames, the installation position of the second positioning frame 4, the position and height of the positioning block 32, and the position and height of the positioning beam 5 can be adjusted with reference to the length, width, and height of the container to adapt the configuration of the top plate platform to the size of the container.

[0028] The roof covering platform is compatible with containers of different lengths. Depending on the container's length, the second positioning frame 4 can be selectively installed on either the first leg 42 or the second leg 43. Specifically, when the second positioning frame 4 is installed on the first leg 42, the distance between the first positioning frame 3 and the second positioning frame 4 is smaller, allowing for roof covering operations on shorter containers; when the second positioning frame 4 is installed on the second leg 43, the distance between the first positioning frame 3 and the second positioning frame 4 is larger, allowing for roof covering operations on longer containers.

[0029] The roof platform is compatible with containers of varying heights. The height of the positioning block 32 and positioning beam 5 can be adjusted according to the container's height. Specifically, for taller containers, the two crossbeams can be raised so that the positioning block 32 and positioning beam 5 are higher than the top of the container, preventing interference between the positioning block 32 and positioning beam 5 and the container during the process of moving the container under the positioning frame.

[0030] The roof platform is compatible with containers of varying widths. The distance between the positioning blocks 322 and the positioning beams 5 on both sides can be set according to the width of the container. Specifically, for wider containers, the two positioning blocks 32 on the crossbeam and the positioning beams 5 on both sides can be spaced further apart, while for narrower containers, the two positioning blocks 32 on the crossbeam and the positioning beams 5 on both sides can be brought closer together, thus making the distance between the positioning blocks 322 and the positioning beams 5 on both sides slightly larger than the width of the container, while this distance should not be too large. After this distance adjustment, by raising the container or lowering the positioning blocks 32 and the positioning beams 5, the positioning blocks 32 can be pressed tightly against the top of the corner piece 61, and the templates 51 of the positioning beams 5 can be pressed against the top side beams 62.

[0031] When positioning the top plate 63, the four positioning blocks 32 are at the same height and distributed along the four corners of a rectangle, while the templates 51 on the positioning beam 5 are distributed parallel to the long side of the rectangle.

[0032] Please refer to Figure 7 The positioning block 32 can be attached to the top of the four corner pieces 61 of the container, and can limit the corner pieces 61 from the side, so that the top of the container can be kept basically on a horizontal plane and the diagonal deviation of the container can be guaranteed.

[0033] The templates 51 of the two side positioning beams 5 are attached to the top side beams 62 of the container. Please refer to this. Figure 2 Each positioning beam 5 has at least two inwardly extending templates 51, and the free ends of the templates 51 on the same positioning beam 5 define a straight line. Specifically, in this embodiment, the inward extension of the templates 51 refers to the templates 51 on one side of the positioning beam 5 extending towards the other side of the positioning beam 5. When the top plate is lowered and released onto the top of the container using a lifting device, these templates 51 serve as a reference and limit. Specifically, it facilitates the lowering of the top plate 63 between the two templates 51, ensuring that the long side of the top plate 63 falls precisely on the top side beam 62, and that the long side of the top plate is substantially parallel to the top side beam 62. This eliminates the need for manual marking on the top side beam 62, improving the efficiency of the top plate installation.

[0034] When the production line switches to a different container size, the configuration of the cover platform can be adjusted accordingly. During mass production of containers, the production line often assembles containers of the same size within a certain timeframe, so adjustments to the cover platform configuration are not very frequent. In one embodiment, a lifting method is preferred, allowing the container to actively align with the positioning block 32. When assembling a batch of containers of the same size, the heights of the first crossbeam 31 and the second crossbeam 41 can remain constant. The heights of the two crossbeams are only adjusted adaptively when switching to containers of different heights. Therefore, for assembling a batch of containers of the same size, the configuration of the cover platform can remain unchanged; only the container needs to be raised or lowered each time the cover is closed.

[0035] In one embodiment, please refer to Figure 1 A hydraulic lift 10 is installed below the lifting frame 1, which can be used to lift containers. Optionally, the hydraulic lift 10 comprises two sets. When lifting shorter containers, one set of hydraulic lifts is activated. When lifting longer containers, both sets of hydraulic lifts are used together.

[0036] In one embodiment, the template 51 can be flipped upward about a pivot axis parallel to the second direction D2. For example, please refer to... Figure 8 One end of the template 51 is connected to the positioning beam 5 via a hinge 52. First, flip the template 51 from its previous lateral extension position to its lateral extension position. At this point, the template 51 fits against the upper surface of the top side beam 62. When the top plate is lowered, the template 51 accurately positions the top plate. After the top plate is installed, flip the template 51 upwards by at least 90° to facilitate container movement.

[0037] In one embodiment, the hanger 1 is a frame consisting of columns and a top beam. Please refer to [reference needed]. Figure 1The hanger 1 includes columns 1a, 1b, 1c and 1d distributed at the four corners of a rectangle, wherein the long side of the rectangle extends along the second direction D2 and the short side of the rectangle extends along the first square.

[0038] The long side of the rectangle is longer than the length of the top plate, and the short side of the rectangle is longer than the width of the container. In other words, the distance between columns 1a and 1b, and the distance between columns 1c and 1d are greater than the length of the top plate, while the distance between columns 1b and 1c and the distance between columns 1d and 1a are greater than the width of the container. This allows the container to enter the jack 1, and the container top plate can be lifted into the jack 1 from the long side of the rectangle. Specifically, the container can be lifted into the jack 1 from between columns 1a and 1b. The container can be moved into the jack 1 from either the front or rear end, specifically from between columns 1a and 1d or between columns 1b and 1c, under the first positioning frame 3 and the second positioning frame 4.

[0039] Wheels can be installed at the bottom of the container to facilitate easy pushing or pulling into the gantry 1. The container can move along the assembly line track, and a mark can be made at the container's stopping position so that when the container stops at the marked position, the top corner piece 61 is substantially directly below the positioning block 32. Of course, those skilled in the art can also use other methods to move the container into the gantry 1 and stop it accurately at the designated position.

[0040] In one embodiment, please refer to Figure 1 The top of the column is connected to a first top beam 11 extending along the second direction D2 and a second top beam 12 extending along the first direction D1. Specifically, the tops of columns 1a and 1b and the tops of columns 1c and 1d are each connected to a first top beam 11; the tops of columns 1b and 1c and the tops of columns 1d and 1a are each connected to a second top beam 12.

[0041] Preferably, please refer to Figure 1 A column 1e is also provided in the middle of one long side of the rectangle. The top of the column 1e supports the corresponding first top beam 11. For example, a column 1e is provided between columns 1c and 1d, and the top of the column 1e supports the first top beam 11 connecting columns 1c and 1d.

[0042] In one embodiment, the lifting frame 1 is equipped with a lifting device for lifting the top of a container. The lifting device, for example, can be an electric hoist, and comprises three sets, such as a first lifting device, a second lifting device, and a third lifting device sequentially along the second direction D2. Please refer to [reference needed]. Figure 1The top beam of the gantry 1 is provided with three load-bearing beams 13 extending along a first direction D1 and spaced apart along a second direction D2. These three load-bearing beams 13 can be fixed to a first top beam 11 and a second top beam 12. Each load-bearing beam 13 is equipped with a lifting device. The three load-bearing beams 13 extend from the long side of the gantry 1, meaning the travel of the lifting device can cover the outside of the gantry 1. The lifting device can lift the container top plate from the outside of the gantry 1 and transfer the container top plate from between the columns 1a and 1b into the gantry 1.

[0043] When hoisting the top of a container, only two of the lifting devices need to be activated. Specifically, activating the first and second lifting devices can lift shorter containers, while activating the first and third lifting devices can lift longer containers.

[0044] In one embodiment, please refer to Figure 3 Two positioning blocks 32 are arranged mirror images of each other below the first crossbeam 31. Each positioning block 32 includes an upper positioning block 321 and a side positioning block 322, wherein the side positioning block 322 extends along the second direction D2 and is disposed on the side edge of the bottom surface of the upper positioning block 321, opposite to the other positioning block 32. Figure 7 The upper positioning block 321 has a flat bottom surface, and the side positioning block 322 extends along the side edge of the bottom surface of the upper positioning block 321 and along the second direction D2. That is, the bottom surface of the upper positioning block 321 can be attached to the top surface of the corner piece 61, and the inner side of the side positioning block 322 can limit the side surface of the corner piece 61. Furthermore, the inner side of the side positioning block 322 has a guide slope that deviates from the other positioning block 32 from top to bottom. In other words, the positioning block 32 is wedge-shaped, wider at the top and narrower at the bottom. When the container is slightly tilted, the guide slope can push the container to center its position during the lifting process.

[0045] In one embodiment, please refer to Figure 3 A mounting base 33 is fixed below the first crossbeam 31, and a vertically arranged suspension rod 34 is connected to the mounting base 33. A positioning block 32 is provided at the lower end of the suspension rod 34. The first crossbeam 31 has two oblong holes extending along a first direction D1. The mounting base 33 is detachably fixed to the oblong holes using fasteners such as bolts and nuts. After removing the fasteners, the position of the mounting base can be adjusted along the oblong holes, thereby manually adjusting the position of the positioning block 32 on the first crossbeam 31.

[0046] In one embodiment, please refer to Figure 3The first positioning frame 3 also includes a first gantry frame 36 and a first lifting device 37 fixed to the first gantry frame 36. The lower end of the first lifting device 37 is connected to a first crossbeam 31, and the first lifting device 37 is used to drive the first crossbeam 31 to rise and fall. For example, the first lifting device 37 includes a worm gear screw jack, wherein the first crossbeam 31 is connected to the lower end of the screw of the worm gear screw jack. The first lifting device 37 comprises two sets, so that the first crossbeam 31 can be kept horizontal and stable.

[0047] In one embodiment, please refer to Figure 1 , Figure 4 and Figure 5 A first positioning frame 3, a first support leg 42, and a second support leg 43 are sequentially arranged in a second direction D2 perpendicular to the first direction D1. The second positioning frame 4 is selectively and detachably mounted on one of the first support leg 42 and the second support leg 43. The second positioning frame 4 includes a liftable second crossbeam 41 extending along the first direction D1, on which a pair of positioning blocks 32 are provided, whose positions are adjustable in the first direction D1. The first support leg 42 and the second support leg 43 each have a pair. The second positioning frame 4 can be selectively mounted on one of the first support leg 42 and the second support leg 43. When the second positioning frame 4 is mounted on the first support leg 42, the distance between the first positioning frame 3 and the second support leg is smaller, allowing for the covering of shorter containers; when the second positioning frame 4 is mounted on the second support leg 43, the distance between the first positioning frame 3 and the second support leg is larger, allowing for the covering of longer containers.

[0048] In one embodiment, please refer to Figure 4 The second positioning frame 4 may include a second gantry frame 44 and a second lifting device 45. The two legs of the second gantry frame 44 may be installed on the two first legs 42 respectively, or on the two second legs 43 respectively.

[0049] The first leg 42 and the second leg 43 can each be two immovable columns, such as I-beams. The first positioning frame 3 can be fixed to the ground and cannot be moved. Compared to the first positioning frame 3, the second gantry frame 44 can be installed on top of either the first leg 42 or the second leg 43. When the second gantry frame 44 is installed on either the first leg 42 or the second leg 43, the first positioning frame 3 and the second positioning frame 4 are at the same height.

[0050] In one embodiment, the second lifting device 45 may include a worm gear screw jack, wherein the second crossbeam 41 is connected to the lower end of the screw of the worm gear screw jack. The second lifting device 45 comprises two sets, thereby keeping the second crossbeam 41 horizontal and stable.

[0051] In one embodiment, the positioning block 32 on the second crossbeam 41 can adopt the same structure and position adjustment method as the positioning block 32 on the first crossbeam 31. That is, the second crossbeam 41 has a waist-shaped hole extending along the first direction D1, and the positioning block 32 is detachably installed at the waist-shaped hole by means of mounting base, bolts and other accessories, so as to realize the manual adjustment of the position of the positioning block 32 on the second crossbeam 41.

[0052] The positioning beams 5 are a pair, located on both sides and extending along the second direction D2. Each positioning beam 5 has a first positioning frame 3 and a second positioning frame 4 connected to its two ends, specifically, to a first crossbeam 31 and a second crossbeam 41, respectively, so that their height can be adjusted synchronously as the two crossbeams are raised and lowered. Since the distance between the first positioning frame 3 and the second positioning frame 4 varies depending on the installation position of the second positioning frame 4, two different lengths of positioning beams 5 can be configured.

[0053] In one embodiment, the end of the positioning beam 5 and the positioning block 32 can be fixed on the same mounting base, and the position of the positioning block 32 and the positioning beam 5 can be adjusted synchronously by moving the mounting base.

[0054] In one embodiment, the positions of the positioning beam 5 and the positioning block 32 in the first direction D1 can be adjusted independently. For example, both ends of each positioning beam 5 are fastened with fasteners such as bolts and nuts to the slotted holes on the first crossbeam 31 and the second crossbeam 41, respectively, so that the positions of the two positioning beams 5 can be adjusted with reference to the width of the container. Containers of the same specifications may have slight design differences. For example, in some designs, the outer side of the corner piece 61 is basically flush with the outer side of the top side beam 62, while in other designs, the corner piece 61 protrudes outward to varying degrees relative to the top side beam 62. The independent adjustment of the position of the positioning beam 5 will provide greater compatibility with the above-mentioned design differences.

[0055] In one embodiment, please refer to Figure 1 and Figure 5 The first positioning frame 3 and the second positioning frame 4 are each provided with a walking platform 7 extending along the first direction D1 on both sides. The walking platform 7 is at a certain height above the ground, allowing people to stand and walk on it for the operation of covering the top of the container.

[0056] In one embodiment, please refer to Figure 5 Below the traveling platform 7, there is also an extension platform 8 that can be pulled out into the lifting frame 1. The extension platform 8 can expand the width of the traveling platform 7. When performing roof covering operations on wide containers, the operator can stand on the traveling platform 7. When performing roof covering operations on narrow containers, the extension platform 8 can be pulled out so that the operator can stand on the extension platform 8 and approach the container.

[0057] In one embodiment, please refer to Figure 1 and Figure 6A roof storage platform 9 is provided next to the lifting frame 1 for storing roof panels. Specifically, the roof storage platform 9 is provided next to the long side of the lifting frame 1, such as the long side defined by the columns 1a and 1b. The roof panels are pre-stored on the roof storage platform 9, and when covering the container with the roof panels, the roof panels on the roof storage platform 9 are directly lifted by the lifting device, so that the distance between the roof panels is closer and time is saved.

[0058] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
