Description

Technical Field

[0001] This utility model relates to the field of transport racks, and more particularly to a foldable and retractable carbon fiber cloth transport rack. Background Technology

[0002] Carbon fiber cloth, as a high-performance composite material, is widely used in high-end manufacturing fields such as aerospace, rail transportation, and wind turbine blades. It has excellent properties such as light weight, high strength, and corrosion resistance. In the intermediate circulation process from production to use, special transportation and turnover equipment is required to carry, protect, and transfer it to ensure that its performance is not affected and to improve handling efficiency.

[0003] Existing turnover racks mostly adopt a fixed frame structure that is welded as a whole. Although this structure is sturdy, when not in use, the huge rigid frame will occupy a lot of storage and transportation space, resulting in low space utilization efficiency and increased costs. Summary of the Invention

[0004] In view of this, the present invention provides a foldable carbon fiber cloth transport turnover rack. The main technical problem to be solved is that existing turnover racks mostly adopt a fixed frame structure with integral welding. Although this structure is sturdy, when not in use, the huge rigid frame will occupy a lot of storage and transportation space, resulting in low space utilization efficiency and increased costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable and retractable carbon fiber cloth transport turnover rack, comprising a telescopic assembly and a enclosure assembly. The telescopic assembly includes two lateral telescopic frames, each rotatably connected to a lateral rotating shaft inside. Side baffles are fixedly connected to the tops of the two lateral telescopic frames. A connecting frame is provided in the middle of the two lateral telescopic frames. Connecting shafts are rotatably connected to the inner walls on both sides of the connecting frame. Two folding plates are provided between the connecting frame and the two lateral telescopic frames. The opposite ends of two adjacent folding plates are fixedly connected to the lateral rotating shaft and the connecting shaft, respectively. A wedge block is fixedly connected to the bottom of each folding plate. A positioning plate is provided between two adjacent folding plates. Two positioning shafts are rotatably connected to the positioning plate. The opposite ends of two adjacent folding plates are fixedly connected to the two positioning shafts, respectively. Multiple self-locking casters are installed at the bottom of both lateral telescopic frames and the connecting frame.

[0006] By adopting the above technical solution, the turnover rack can be quickly folded, unfolded and fixed during transportation, and folded and stored when not in use, saving space.

[0007] As a further description of the above technical solution:

[0008] The two side baffles have multiple hollowed-out grooves inside, and the multiple self-locking casters at the bottom of the two side telescopic frames and the connecting frame are evenly distributed in an array.

[0009] By adopting the above technical solutions, the hollowed-out groove reduces the overall weight, and the arrangement of the self-locking universal wheel array improves the stability of movement and the uniformity of load bearing.

[0010] As a further description of the above technical solution:

[0011] The enclosure assembly includes two enclosure panels, which are located at the front and rear ends of the two side panels respectively. Two limiting strips are fixedly connected to the opposite surfaces of the two enclosure panels. Limiting grooves are formed at the front and rear ends of the two enclosure panels, and the limiting strips are located inside the corresponding limiting grooves.

[0012] By adopting the above technical solution, the two panels can be quickly connected and locked laterally, which is convenient for disassembly and assembly and ensures reliable connection.

[0013] As a further description of the above technical solution:

[0014] Multiple inserts are fixedly connected to the bottom of both enclosures, and limit frames are fixedly connected to the front and rear ends of both side panels and connecting frames, with the inserts inserted into the interior of the corresponding limit frames.

[0015] By adopting the above technical solution, the cooperation between the insert block and the limiting frame achieves a stable fixation of the bottom of the enclosure, preventing it from shaking during transportation.

[0016] As a further description of the above technical solution:

[0017] Each of the two enclosure panels has a hanging plate fixedly connected to its opposite side. Each of the two side panels has a rectangular groove on its top. The hanging plate is L-shaped and its position corresponds to the position of the rectangular groove. The rectangular groove and the hanging plate are matched.

[0018] By adopting the above technical solution, when the turnover rack is in a folded state, the L-shaped hanging plate is hung into the rectangular groove at the top of the side baffle, so that the side panel is hung on the side baffle.

[0019] As a further description of the above technical solution:

[0020] The cross-sections of the limiting strip and the limiting groove are both T-shaped, and multiple evenly distributed through holes are opened inside the two enclosures.

[0021] By adopting the above technical solution, the T-shaped structure improves the firmness of the connection, and the through hole reduces the weight of the enclosure, making it easier to handle.

[0022] By employing the above technical solution, the foldable and retractable carbon fiber cloth transport turnover rack of this utility model has at least the following beneficial effects:

[0023] 1. Compared with existing technologies, this foldable carbon fiber cloth transport turnover rack achieves stepless adjustment of the overall width and rapid folding function by setting up a telescopic assembly consisting of two lateral telescopic frames, a connecting frame, and multiple rotatable folding plates connected therebetween. During loading and transportation, the lateral telescopic frames unfold outward, driving the folding plates to rotate around the lateral and connecting shafts to flatten them, and are fixed by positioning plates. During storage, it can be quickly folded and folded up, reducing the space occupied and solving the problems of low space utilization and poor adaptability of traditional welded fixed turnover racks.

[0024] 2. Compared with existing technologies, this foldable carbon fiber cloth transport turnover rack, through the design of a fence assembly consisting of two enclosure panels, limiting strips, limiting grooves, inserts, limiting frames, hanging plates, and rectangular grooves, achieves modularity, quick assembly and disassembly, and reliable fixation of the fence. During installation, the T-shaped interlocking of the limiting strips and limiting grooves enables quick docking and lateral locking of the enclosure ends. The insertion of the inserts into the limiting frames achieves vertical positioning at the bottom, and the hanging plates are hung into the rectangular grooves for auxiliary fixation at the top, forming a stable and reliable rectangular protective space. This effectively prevents the carbon fiber cloth from shifting, slipping, or being damaged during transportation. The disassembly process is also convenient, greatly improving the efficiency of loading and unloading operations. Attached Figure Description

[0036] 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.

[0037] Reference Figure 1-9This utility model provides a foldable and retractable carbon fiber fabric transport rack, comprising a telescopic assembly 1 and a enclosure assembly 2. The telescopic assembly 1 includes two lateral telescopic frames 101, each rotatably connected to a lateral rotating shaft 102. Side baffles 103 are fixedly connected to the top of each lateral telescopic frame 101. A connecting frame 104 is provided between the two lateral telescopic frames 101, with connecting shafts 105 rotatably connected to the inner walls of both sides of the connecting frame 104. Two folding plates 106 are provided between the connecting frame 104 and the two lateral telescopic frames 101, with the opposite ends of two adjacent folding plates 106 fixed to the lateral rotating shaft 102 and the connecting shaft 105, respectively. The bottom of the folding plate 106 is fixedly connected to a wedge block 107. Both the folding plate 106 and the wedge block 107 are made of ultra-high strength steel to ensure their load-bearing capacity. A positioning plate 108 is set between two adjacent folding plates 106. The positioning plate 108 is rotatably connected to two positioning shafts 109. The opposite ends of two adjacent folding plates 106 are fixedly connected to the two positioning shafts 109 respectively. Multiple self-locking casters 110 are installed at the bottom of the two lateral telescopic frames 101 and the connecting frame 104. Multiple hollow slots are opened inside the two side baffles 103. The multiple self-locking casters 110 at the bottom of the two lateral telescopic frames 101 and the connecting frame 104 are evenly distributed in an array.

[0038] When this turnover rack is needed for transportation, first operate the telescopic component 1. By pulling the two lateral telescopic frames 101, they unfold outward in the horizontal direction, causing the two lateral rotating shafts 102 to move synchronously. The unfolding of the lateral telescopic frames 101 simultaneously pulls the folding plates 106 connected to them to rotate around the lateral rotating shafts 102 and the connecting rotating shaft 105, so that multiple folding plates 106 gradually unfold from the folded state and tend to be laid flat, forming an expanded load-bearing bottom. During this process, the wedge-shaped blocks 107 fixed to the bottom of the folding plates 106 can provide structural reinforcement and assist in limiting the position. After unfolding into place, two adjacent folding plates 106 are connected and relatively fixed to each other through the positioning plate 108 and the positioning rotating shaft 109 on it, thereby maintaining the stable unfolded shape of the entire load-bearing bottom and realizing the flexible adjustment of the width of the turnover rack.

[0039] When folding the turnover rack, first disassemble the enclosure assembly 2, lift the enclosure 201 upwards to disengage the insert 204 from the limiting frame 205, then separate the two enclosures 201 along the limiting groove 203, and then pull the limiting frames 205 connected to the front and rear ends of the positioning plate 108 upwards respectively, so that the two positioning plates 108 drive one end of the folding plate 106 connected to them to move synchronously, so that the two folding plates 106 connected to them flip, thereby causing the folding plate 106 connected to the lateral telescopic frame 101 to flip synchronously, and finally push the two lateral telescopic frames 101 synchronously towards each other, so that the entire turnover rack can be folded again, and the entire turnover rack can be folded to the minimum width state.

[0040] The enclosure assembly 2 includes two enclosure panels 201, which are located at the front and rear ends of two side panels 103 respectively. Two limiting strips 202 are fixedly connected to the opposite surfaces of the two enclosure panels 201. Limiting grooves 203 are opened at the front and rear ends of the two enclosure panels 201, and the limiting strips 202 are located inside the corresponding limiting grooves 203. Multiple inserts 204 are fixedly connected to the bottom of the two enclosure panels 201. Limiting frames 205 are fixedly connected to the front and rear ends of the two side panels 103 and the connecting frame 104. The inserts 204 are inserted into the corresponding limiting frames 205. Hanging plates 3 are fixedly connected to the opposite surfaces of the two enclosure panels 201. Rectangular grooves 4 are opened at the top of the two side panels 103. The hanging plates 3 are L-shaped, and the position of the hanging plates 3 corresponds to the position of the rectangular grooves 4 and matches the rectangular grooves 4 with the hanging plates 3. The cross-sections of the limiting strips 202 and the limiting grooves 203 are T-shaped. Multiple evenly distributed through holes are opened inside the two enclosure panels 201.

[0041] After the bottom of the support is unfolded and fixed, the enclosure assembly 2 is installed. The two enclosure panels 201 are placed in the front and rear positions of the side baffles 103 on both sides. During installation, the limiting strip 202 on one enclosure panel 201 is aligned and slid into the corresponding limiting groove 203 on the other enclosure panel 201. The mutual cooperation of the T-shaped cross sections realizes the quick docking and lateral locking of the two enclosure panels 201 at the ends, forming the front and rear enclosures together. At the same time, the multiple inserts 204 at the bottom of the enclosure panel 201 are aligned and inserted into the limiting frames 205 fixed at the front and rear ends of the side baffles 103 and the connecting frame 104, so that the enclosure panel 201 is vertically positioned at the bottom, so that the entire turnover frame forms a rectangular space, which is used to store carbon fiber cloth.

[0042] After the above assembly is completed, the carrying platform and enclosure of the turnover rack are in place. Carbon fiber rolls or sheets can be placed in the space defined by the side baffle 103, the connecting frame 104, the unfolded folding plate 106 and the two enclosure plates 201 for transportation. When moving, the multiple self-locking casters 110 installed at the bottom of the lateral telescopic frame 101 and the connecting frame 104 can be unlocked and used for flexible movement and turning. After reaching the destination, the self-locking casters 110 can be locked to fix the position of the turnover rack.

[0043] Working principle: When the turnover rack is needed for transportation, first operate the telescopic component 1. By pulling the two lateral telescopic frames 101, they are unfolded outward in the horizontal direction, which drives the two lateral rotating shafts 102 to move synchronously. The unfolding of the lateral telescopic frames 101 simultaneously pulls the folding plates 106 connected to them to rotate around the lateral rotating shafts 102 and the connecting rotating shafts 105, so that multiple folding plates 106 gradually unfold from the folded state and tend to be laid flat, forming an expanded load-bearing bottom. During this process, the wedge blocks 107 fixed to the bottom of the folding plates 106 can provide structural reinforcement and assist in limiting the position. After unfolding into place, the two adjacent folding plates 106 are connected and relatively fixed by the positioning plate 108 and the positioning rotating shaft 109 on it, thereby maintaining the stable unfolded shape of the entire load-bearing bottom and realizing the flexible adjustment of the width of the turnover rack.

[0044] After the bottom of the support is unfolded and fixed, the enclosure assembly 2 is installed. The two enclosure panels 201 are placed in the front and rear positions of the side baffles 103 on both sides. During installation, the limiting strip 202 on one enclosure panel 201 is aligned and slid into the corresponding limiting groove 203 on the other enclosure panel 201. The mutual cooperation of the T-shaped cross sections realizes the quick docking and lateral locking of the two enclosure panels 201 at the ends, forming the front and rear enclosures together. At the same time, the multiple inserts 204 at the bottom of the enclosure panel 201 are aligned and inserted into the limiting frames 205 fixed at the front and rear ends of the side baffles 103 and the connecting frame 104, so that the enclosure panel 201 is vertically positioned at the bottom, so that the entire turnover frame forms a rectangular space, which is used to store carbon fiber cloth.

[0045] After the above assembly is completed, the carrying platform and enclosure of the turnover rack are in place, and carbon fiber rolls or sheets can be placed in the space defined by the side baffles 103, connecting frame 104, unfolded folding plate 106, and two enclosures 201 for transportation. During movement, multiple self-locking casters 110 installed at the bottom of the lateral telescopic frame 101 and connecting frame 104 can be unlocked and used for flexible movement and turning. After reaching the destination, the self-locking casters 110 can be locked to fix the position of the turnover rack.

[0046] When the turnover rack is in the folded state, the L-shaped hanging plate 3 is hooked into the rectangular groove 4 at the top of the side baffle 103, so that the enclosure 201 is hooked on the side baffle 103. When folding the turnover rack, first disassemble the enclosure assembly 2, lift the enclosure 201 upward so that the insert 204 is disengaged from the limiting frame 205, then separate the two enclosures 201 along the direction of the limiting groove 203, and then pull the limiting frames 205 connected to the front and rear ends of the positioning plate 108 upward respectively, so that the two positioning plates 108 drive one end of the folding plate 106 connected to them to move synchronously, so that the two folding plates 106 connected to them flip, so that the folding plates 106 connected to the lateral telescopic frame 101 flip synchronously, and finally push the two lateral telescopic frames 101 synchronously towards each other, so that the entire turnover rack can be folded again, and the entire turnover rack can be folded to the minimum width state.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
