Description

Technical Field

[0001] This utility model relates to the field of sheet material storage equipment, and in particular to a sheet material feeding platform. Background Technology

[0002] In industrial production, for large raw material sheets, such as those 10-13 meters long, a dedicated material handling area is typically planned within the factory to make efficient use of space. Currently, the industry commonly uses a stacking method, where sheets of various sizes are piled together on the floor of the material handling area. While this storage method effectively saves space, it reveals significant drawbacks in practical use: when a sheet of a specific size needs to be retrieved, it is necessary to rely on overhead cranes or other lifting equipment to lift all the different sizes of sheets stacked above that sheet one by one before the target sheet can be transferred.

[0003] Each time the bottom or middle layer of panels is retrieved, multiple overhead crane operations are required for high-altitude hoisting. A single retrieval process involves multiple steps, including "locating the upper layer panel - hoisting and transferring - repeating the operation until the target panel is exposed - secondary hoisting of the target panel," which is time-consuming. This process not only carries the risk of collision damage to the panels due to crane operation errors, but the frequent hoisting operations also cause excessive wear and tear on the lifting equipment, increasing equipment maintenance costs.

[0004] In existing technologies, the traditional stacking storage method in the material unloading area essentially relies on a "top-to-bottom" retrieval logic, without designing a dedicated storage and sorting structure for the size differences of large-sized boards and the need for efficient retrieval. When the production line uses boards frequently, the above problems will force the production cycle to slow down. Especially in the scenario of mixed processing of multiple specifications of boards, the problem of low retrieval efficiency is more prominent, which has become a bottleneck restricting the automation upgrade of board processing production lines. Utility Model Content

[0005] Therefore, it is necessary to provide a board feeding platform that can efficiently pick up boards, addressing the technical problem of low board picking efficiency.

[0006] To achieve the above objectives, this utility model provides a sheet material feeding platform, including a frame. Two layers of tracks are arranged vertically on the frame, and a walking platform is arranged on each layer of tracks. A bottom feeding space can be formed below the lower walking platform, and a middle feeding space can be formed between the two walking platforms. The walking platform includes a platform body and a walking trolley. The walking trolley includes a trolley shell, a rotary drive element, and track wheels. The trolley shell is fixedly connected to the platform body, the rotary drive element is fixedly connected to the trolley shell, the track wheels are rotatably connected to the trolley shell, and the track wheels are rollingly connected to the tracks. The rotary drive element drives the track wheels to rotate.

[0007] Preferably, the platform body includes a main beam, a crossbeam, and diagonal braces. There are at least two main beams and multiple crossbeams. The crossbeams are fixedly installed on the top of the main beams and connect to each main beam. The trolley shell is fixedly connected to the main beams.

[0008] Preferably, the platform body also includes diagonal bracing, with diagonal bracing fixed at both ends of the horizontal bracing. The end of the diagonal bracing away from the horizontal bracing is inclined downward and fixedly connected to the main beam.

[0009] Preferably, the platform body also includes crossbeams, with multiple parallel crossbeams fixed between each two adjacent main beams.

[0010] Preferably, the main beam includes an upper plate, a vertical plate, a lower inclined plate, and a bottom plate. The upper plate is located directly above the bottom plate. Multiple vertical plates are fixedly arranged between the upper plate and the bottom plate. Both ends of the bottom plate are fixed to the lower inclined plate. The lower inclined plate is fixedly connected to the vertical plate. Both ends of the vertical plate are provided with L-shaped notches. The trolley shell is fixedly connected to the inner wall of the L-shaped notch.

[0011] Preferably, the main beam further includes a lower inclined plate, both ends of the bottom plate are fixed with lower inclined plates, the lower inclined plates are fixedly connected to the vertical plate, and the end of the lower inclined plate away from the bottom plate is inclined upward and fixedly connected to the trolley shell.

[0012] Preferably, track fixing plates are provided on both sides of the track, and the track is fixedly installed on the frame by the track fixing plates.

[0013] Preferably, the frame is configured as two, and the frame includes a pad, a column, and an I-beam. There are two pads, and a column is fixed on each pad. The I-beams are arranged in two layers, and each I-beam corresponds to a track. The track is fixedly installed on the top of the corresponding I-beam. The bottom of the lower I-beam is fixedly connected to the pad, and the bottom of the upper I-beam is fixedly connected to the top of the column.

[0014] Preferably, a blocking plate is fixed to the top of the column, and the ends of the I-beams and the tracks located on the upper layer are fixedly connected to the blocking plate. The height of the top of the blocking plate is higher than the height of the top of the track located on the upper layer.

[0015] Preferably, the width of the platform body is less than half the length of the track.

[0016] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0017] 1. The design of double-layer track and walking platform forms three independent material feeding spaces at the bottom, middle and top, supporting the layered storage of 2-4 specifications of boards without the need for messy stacking of boards; the target board can be quickly exposed by moving the walking platform, which is convenient for overhead crane hoisting and improves the efficiency of board picking.

[0018] 2. When feeding more than 4 types of boards, the commonly used boards can be placed on the main body of the platform, thereby reducing the number of board specifications stacked in the bottom feeding space and shortening the time required to retrieve the target board in the bottom feeding space.

[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] Please see Figures 1 to 5 This application provides a sheet material feeding platform, including a frame 1. Two layers of tracks 2 are vertically arranged on the frame 1, with two tracks in each layer. Each layer of tracks 2 has a walking platform 3. A bottom feeding space is formed below the lower walking platform 3, a middle feeding space is formed between the two walking platforms 3, and an upper feeding space is formed above the upper walking platform 3.

[0027] The traveling platform 3 includes a platform body 31 and a traveling trolley 32. The traveling trolley 32 includes a trolley housing 321, a rotary drive element 322, and a track wheel 323. The trolley housing 321 is fixedly connected to the platform body 31, the rotary drive element 322 is fixedly connected to the trolley housing 321, and the track wheel 323 is rotatably connected to the trolley housing 321. Bearings are installed on the trolley housing 321, and the axle of the track wheel 323 is connected to the inner ring of the bearing, thereby realizing the rotatable connection between the track wheel 323 and the trolley housing 321. The track wheel 323 is rolledly connected to the track 2, and the rotary drive element 322 drives the track wheel 323 to rotate.

[0028] The rotary drive element 322 is a geared motor. The output end of the rotary drive element 322 is connected to the track wheel 323 to directly drive the track wheel 323 to rotate; or the output end of the rotary drive element 322 is connected to the track wheel 323 through a gear assembly to drive the track wheel 323 to rotate; or the output end of the rotary drive element 322 is connected to the track wheel 323 through a chain drive assembly to drive the track wheel 323 to rotate.

[0029] The platform body 31 is 15m long and 3.6m wide, which makes it easy to place boards up to 14m long.

[0030] The structure adopts a double-layer track 2 arranged vertically. The track wheel 323 is driven to move on the track 2 by the rotary drive element 322, which allows the two platform bodies 31 to move relative to each other. When the two platform bodies 31 are at their farthest distance, the plates on the two platform bodies 31 can be fully exposed in the area that the hoisting equipment can hoist.

[0031] For the placement of the four specifications of boards, the four specifications of boards can be placed on the upper platform body 31, the lower platform body 31 and the bottom material storage space respectively. The boards in the bottom material storage space are supported by the ground. The two specifications of boards in the bottom material storage space are placed in two stacks. In this way, by moving the traveling platform 3, the target specification of board can be exposed to the position where the overhead crane can directly lift it, realizing the layered storage and retrieval of boards. The boards are easy to retrieve and the efficiency is high.

[0032] For the placement of four or more specifications of sheet metal, two commonly used specifications can be placed on the upper platform body 31 and the lower platform body 31 respectively, while less commonly used specifications can be placed in the bottom material loading space. By moving the traveling platform 3, the target specifications of sheet metal on the upper and lower platform bodies 31 can be exposed to a position where the overhead crane can directly lift them. Since the total number of specifications of the less commonly used specifications placed in the bottom material loading space is reduced to two, the number of sheet metals that need to be transferred when retrieving them is also reduced, which can shorten the time required to obtain the target sheet metal and improve efficiency.

[0033] In a preferred embodiment, please refer to Figure 1 To improve the structural strength of the platform body 31, the platform body 31 includes main beams 311, cross braces 312, and diagonal braces 313. There are three main beams 311 and multiple cross braces 312, which are equidistantly spaced and fixedly installed on the top of the main beams 311, connecting each main beam 311. The trolley shell 321 is fixedly connected to the main beams 311. Plates are placed on the cross braces 312.

[0034] Based on the above embodiments, to further improve the structural strength of the platform body 31, please refer to... Figure 1 and Figure 3 In this embodiment, the platform body 31 also includes diagonal braces 313. Both ends of the horizontal brace 312 are fixed with diagonal braces 313. The end of the diagonal brace 313 furthest from the horizontal brace 312 is inclined downwards and fixedly connected to the main beam 311. The main beam 311 extends from both ends of the horizontal brace 312. The diagonal braces 313 connect to the ends of the horizontal brace 312, providing support to the ends of the horizontal brace 312 and improving its structural strength.

[0035] Based on the above embodiments, to further improve the structural strength of the platform body 31, please refer to... Figure 1 The platform body 31 also includes crossbeams 314, with multiple parallel crossbeams 314 fixed between each pair of adjacent main beams 311. The crossbeams 314 are evenly spaced, which further improves the connection strength of each main beam 311, thereby increasing the structural strength of the platform body 31.

[0036] Based on the above embodiments, to ensure the structural strength of the main beam 311, please refer to... Figure 3 and Figure 5 The main beam 311 includes an upper plate 3111, a vertical plate 3112, a lower inclined plate 3113, and a bottom plate 3114. The upper plate 3111 is located directly above the bottom plate 3114. Three vertical plates 3112 are fixedly arranged between the upper plate 3111 and the vertical plates 3112 of the bottom plate 3114. Both ends of the bottom plate 3114 are fixed to the lower inclined plate 3113. The lower inclined plate 3113 is fixedly connected to the vertical plates 3112. Both ends of the vertical plates 3112 are provided with L-shaped notches. The trolley shell 321 is fixedly connected to the inner wall of the L-shaped notches.

[0037] The L-shaped notch design ensures that the trolley shell 321 stably supports the main beam 311, while also reducing the overall height of the main beam 311 and the trolley shell 321.

[0038] Based on the above embodiments, to prevent impurities from entering the inner cavity of the main beam 311, please refer to... Figure 5The main beam 311 also includes a lower inclined plate 3113. Both ends of the base plate 3114 are fixed with lower inclined plates 3113. The lower inclined plates 3113 are fixedly connected to the vertical plate 3112. The end of the lower inclined plate 3113 away from the base plate 3114 is inclined upwards and fixedly connected to the trolley housing 321. The lower inclined plate 3113 not only seals the inner cavity of the main beam 311 but also prevents contact with the track 2. Because of the size limitations of the trolley housing 321, the lower inclined plate 3113 needs to be inclined; if it were vertical, it would contact the track 2 and interfere with it.

[0039] In a preferred embodiment, to facilitate fixing the track 2 to the frame 1, track fixing plates 21 are provided on both sides of the track 2, and the track 2 is fixedly installed on the frame 1 by means of the track fixing plates 21. The lower end of the track fixing plate 21 is welded to the frame 1. Specifically, the track fixing plate 21 fixes the track 2 to the frame 1 by pressing down on the track 2, or the track 2 can be fixed to the frame 1 by welding the track fixing plate 21 to the track 2.

[0040] In a preferred embodiment, for ease of installation of track 2, please refer to [link / reference needed]. Figure 1 The frame 1 is configured as two, and the frame 1 includes a pad 11, a column 12, and an I-beam 13. There are two pads 11, and a column 12 is fixed on each pad 11. The I-beams 13 are arranged in two layers, and the I-beams 13 correspond one-to-one with the rails 2. The rails 2 are fixedly installed on the top of the corresponding I-beams 13. The bottom of the lower I-beam 13 is fixedly connected to the pad 11 and close to the column 12. The bottom of the upper I-beam 13 is fixedly connected to the top of the column 12.

[0041] The column 12 supports the weight of the upper walking platform 3, while the pad 11 supports the weight of the lower walking platform 3. This design forms a double-layer three-dimensional support structure, which avoids the problem of concentrated load on the column 12 and improves the deformation resistance of the frame 1.

[0042] Based on the above embodiment, in order to prevent the upper-level traveling trolley 32 from derailing, a blocking plate 121 is fixed to the top of the column 12. The ends of the upper-level I-beam 13 and the upper-level track 2 are both fixedly connected to the blocking plate 121. The top height of the blocking plate 121 is higher than the top height of the upper-level track 2.

[0043] The blocking plate 121 can form a safety limit structure, which limits the extreme position of the walking platform 3, prevents derailment, and ensures the safe operation of the equipment.

[0044] In a preferred embodiment, to ensure that the traveling trolley 32 has sufficient travel distance on the track 2, and to ensure that when the two platform bodies 31 are at their furthest distance, the plates on both platform bodies 31 are fully exposed within the area that the lifting equipment can lift, please refer to [reference needed]. Figure 1 and Figure 2 The width of the platform body 31 is set to be less than half the length of the track 2. In this way, when the two platform bodies 31 are at their farthest distance, their vertical projections will not overlap, and the plates on the two platform bodies 31 can be fully exposed in the area that the hoisting equipment can lift, before they extend beyond the edge of the platform body 31, making them easy to use.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
