Description

Technical Field

[0001] This invention relates to the field of storage system technology, and more specifically, to a high-efficiency profile gantry storage system. Background Technology

[0002] With the booming development of the warehousing industry, the coverage area of ​​warehouses has gradually shifted from back-end products to mid-to-front-end products. Previously, raw materials with lower added value have gradually entered the warehousing coverage area due to market expansion, material price fluctuations, and customized demands. However, the storage of raw materials has traditionally been haphazard, with sheets stacked on top of each other and profiles stored in designated areas according to specifications. Due to space limitations, overhead crane operations are the primary method, with a few companies adding cantilever racks for differentiation. Because of this ground-level storage, materials are disorganized, inefficiently utilized, and wasteful. Therefore, dedicated storage systems are often needed for specific profiles.

[0003] However, existing profile storage systems have fixed clamping and bearing structure parameters, making it difficult to adjust clamping spacing, tilt angle, and support height. A single device can only handle the transfer and storage of a single profile. When handling rectangular tubes, cylindrical tubes, trapezoidal tubes, or plate-shaped profiles, the corresponding clamping fixtures must be disassembled and replaced, resulting in a narrow range of applicability. Furthermore, the lack of a stepless width adjustment structure makes it difficult to adapt to profiles of different widths. Therefore, we propose a highly efficient profile gantry storage system.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. This invention integrates a multi-adjustable clamping and bearing structure with adjustable spacing, angle, and lifting. A single device can be compatible with the transfer and storage of four types of cross-section profiles: cuboid tubes, cylindrical tubes, trapezoidal tubes, and plate-shaped profiles without changing the clamping fixture. The telescopic drive component drives the moving seat to achieve stepless adjustment of the clamping width, which can adapt to profiles of various widths. The symmetrically inclined side baffles on both sides form inclined slots to adapt to trapezoidal profiles. With flexible connectors, the gap is sealed and adjusted to prevent the corners of the profiles from getting stuck. The independently adjustable bottom support has an arc-shaped groove in the middle to limit the round tube and prevent rolling. When working with plates and square tubes, the bottom support can be lowered to rely on the side clamping, providing differentiated support for different profiles.

[0032] 2. This invention integrates a guide groove, a compensating slider, a return spring, a torsion spring, and an adaptive follower plate into the bottom adjustment structure to form an adaptive fitting component. This component can work in tandem with the lateral adjustment structure to move synchronously. The return spring drives the compensating slider to slide along the guide groove for compensation, automatically adapting to the opening and closing of the side baffle and changes in tilt angle. This eliminates mechanical gaps, prevents structural jamming and material suspension, and ensures continuous and smooth deformation of the clamping space. The torsion spring continuously outputs preload force, causing the follower plate to adaptively deflect with the tilt angle of the side baffle, tightly fitting the inner wall and eliminating clamping dead angles and false clamping phenomena. This achieves full-envelope precise positioning for rectangular, trapezoidal, plate, and cylindrical profiles. This mechanism, combined with the arc-shaped groove of the bottom support, forms a composite limiting system of lateral adaptive fitting and bottom support. Round tubes can be prevented from rolling, and irregularly shaped and plate materials can be completely fitted and clamped. This comprehensively improves the clamping fit, operational stability, and structural linkage adaptability of multi-section profiles, broadens the equipment's versatility, and optimizes the quality of automated warehousing and transfer operations for profiles.

[0033] 3. This invention integrates an adaptive clamping assembly consisting of a rotary actuator, transmission gears, an arc-shaped force-applying rod, and a clamping contact on the side baffle. The precise feeding and extension of the arc-shaped force-applying rod is achieved through gear meshing transmission. The arc-shaped force-applying rod adopts an arc-shaped rod structure and is slidably mounted on the side baffle. It can adaptively slide in an arc shape following the vertical and inclined deformation states of the side baffle, without any motion interference or jamming throughout the process. The clamping stroke and clamping angle can be adapted in real time to the deformation of the clamping space, always maintaining a perpendicular fit between the clamping contact and the side wall of the profile. It is compatible with the lateral clamping and fixing requirements of cuboid, cylindrical, trapezoidal, and plate profiles, exhibiting extremely strong versatility and adaptability.

[0053] Examples, such as Figures 1 to 12As shown, the present invention relates to a high-efficiency profile gantry storage system, including a handling device 1; the handling device 1 includes a gantry frame 101, a movable base 102, a traveling track 103, and a lifting drive unit 104. Movable bases 102 are installed at both bottom ends of the gantry frame 101, and the gantry frame 101 slides along the traveling track 103 via the movable bases 102. The lifting drive unit 104 is installed at the top of the gantry frame 101, and the lifting drive unit 104 drives a frame assembly 2 to adjust the height along the gantry frame 101; the frame assembly 2 includes a base frame 203 and a lateral adjustment structure. The base frame 203 is installed at the output end of the lifting drive unit 104, and four independent chambers are equally spaced on the base frame 203. Each independent chamber is equipped with a lateral adjustment structure 201 and a bottom adjustment structure 202. A clamping space is formed between the lateral adjustment structure 201 and the bottom adjustment structure 202 in each independent chamber. The clamping space can be deformed by changing the lateral adjustment structure 201 and the bottom adjustment structure 202. The deformed clamping space can be adapted to cuboid profiles, cylindrical profiles, trapezoidal profiles and plate profiles.

[0054] The lateral adjustment structure 201 includes a side baffle 2011, a movable seat 2012, a telescopic drive component 2013, a rotary power component 2014, a transmission screw 2015, a transmission block 2016, and a transmission connecting rod 2017. The movable seat 2012 is slidably connected to the independent chamber. The telescopic drive component 2013 is installed inside the movable seat 2012, and its output end passes through the movable seat 2012 and is connected to the independent chamber. The telescopic drive component 2013 is used to push the movable seat 2012 to move within the independent chamber. The side baffle 2011 is rotatably connected to the movable seat 2012 via a connecting seat. The end of the side baffle 2011 is connected to the opening edge of the base frame 203 by a flexible connector 204. The two ends of the transmission connecting rod 2017 are rotatably connected to the side baffle 2011 and the transmission screw block 2016 respectively. The transmission screw block 2016 is threadedly connected to the transmission screw 2015 and slidably connected to the movable seat 2012. One end of the transmission screw 2015 is installed on the movable seat 2012, and the other end of the transmission screw 2015 passes through the movable seat 2012 and is connected to the output end of the rotating power component 2014. The rotating power component 2014 is installed on the movable seat 2012.

[0055] The bottom adjustment structure 202 includes a bottom support 2021, a telescopic drive unit 2022, and an arc-shaped groove 2023. The bottom support 2021 is installed at the output end of the telescopic drive unit 2022, the telescopic drive unit 2022 is installed in an independent chamber, and the arc-shaped groove 2023 is opened in the middle of the bottom support 2021 and is adapted to a cylindrical profile.

[0056] Working principle: The handling device 1 serves as the main handling mechanism of the equipment. During operation, the gantry frame 101 slides laterally along the travel track 103 via the movable bases 102 on both sides of the bottom, achieving rapid horizontal alignment of the entire machine and completing the switching of profile picking, transfer, and unloading stations. The lifting drive unit 104 mounted on the top of the gantry frame 101 can drive the frame assembly 2 below to rise and fall vertically along the gantry frame 101, adjusting the working height of the handling assembly to adapt to the picking and unloading operations of profiles with different stacking heights and specifications, providing an alignment basis for subsequent profile clamping; the frame assembly 2 rises and falls synchronously with the lifting drive unit 104, and the base frame 203 is fixed to the output end of the lifting drive unit 104. Four independent chambers are equally spaced on the base frame 203, and each chamber is independently equipped with a lateral adjustment structure 201 and a bottom adjustment structure 202, forming a deformable clamping space independently. The four clamping spaces can be adjusted synchronously or independently to realize the synchronous handling of multiple profiles in a single batch, greatly improving the efficiency of profile storage and transfer; the telescopic drive component 2013 is fixed inside the movable seat 2012, and its output end passes through the movable seat 2012 and is fixedly connected to the independent chamber; when the telescopic drive component 2013 telescopically moves, it can push and pull the movable seat 2012 in the opposite direction to slide horizontally along the inside of the independent chamber, changing the relative distance between the two movable seats 2012, thereby adjusting the overall clamping width of the clamping space, realizing the adaptive clamping of profiles of different widths, and avoiding slippage due to excessively loose clamping or deformation due to excessively tight clamping. During operation, the rotating power component 2014 drives the transmission screw 2015 to rotate. Under the action of the threaded engagement, the transmission screw block 2016 slides along the axial direction of the transmission screw 2015. The transmission screw block 2016 pushes and pulls the side baffle 2011 through the transmission connecting rod 2017, causing the side baffle 2011 to rotate and deflect around the bottom connecting seat. The end of the side baffle 2011 is flexibly connected to the opening edge of the base frame 203 through the flexible connector 204, which not only ensures the flexibility of angle adjustment, but also seals the adjustment gap and avoids structural jamming. Through the symmetrical angle deflection of the two side baffles 2011, the clamping space can form different cross-sectional shapes such as straight grooves and inclined grooves, which can be adapted to the side fitting and positioning of trapezoidal profiles and plate profiles. The bottom adjustment structure 202 serves as a bottom support mechanism for profiles, used to adapt to the curved surface fitting of cylindrical profiles and the height compensation of profiles of different thicknesses. The telescopic drive unit 2022 can drive the top base 2021 to rise and fall vertically, adjusting the support height of the base 2021. An arc-shaped groove 2023 is provided in the middle of the base 2021, which can precisely fit the arc-shaped outer wall of the cylindrical profile, achieving limited support for the cylindrical profile and preventing it from rolling or shifting. For sheet metal and square profiles, the height of the base 2021 can be lowered, allowing the profile to be clamped and positioned by the side baffles 2011 on both sides, achieving bottom-adaptive support for profiles with different cross-sections.

[0057] For rectangular profiles: Adjust the lateral adjustment structure 201 so that the side baffle 2011 fits against the two sides of the square tube, reset and keep the side baffle 2011 in a vertical state, and the bottom support 2021 of the bottom adjustment structure 202 is moderately lifted to form a rectangular clamping cavity to stably clamp the rectangular profile.

[0058] For cylindrical profiles: reduce the distance between the two side baffles 2011, lift the bottom support 2021 and use the central arc groove 2023 to support the bottom of the round tube, and limit the rolling of the two vertical side baffles 2011 to achieve stable clamping and handling of the round tube;

[0059] For trapezoidal profiles: The lateral adjustment structure 201 drives the two side baffles 2011 to tilt symmetrically inward, so that the two side baffles 2011 form trapezoidal grooves that are narrow at the top and wide at the bottom or wide at the top and narrow at the bottom, which precisely fit the oblique contour of the trapezoidal profile and realize the fitting and clamping of irregular trapezoidal profiles.

[0060] During operation, the gantry 101 travels and aligns with the profile stacking station. The frame assembly 2 is lowered by the lifting drive unit 104. According to the specifications of the profile to be transported, the spacing, angle and lifting structure of each chamber are adaptively adjusted so that the clamping space deforms to match the shape of the profile and completes precise clamping. After the clamping is stable, the lifting drive unit 104 lifts the profile, and the gantry 101 moves along the travel track 103 to the storage station. Finally, the profile is lowered to unload, completing the automated storage, retrieval, transfer and storage operation.

[0061] This invention is highly versatile. One set of equipment can be used to transfer and store four types of materials with different cross-sections: cuboid profiles, cylindrical profiles, trapezoidal profiles, and plate profiles. There is no need to change clamping tooling of different specifications, which greatly reduces the cost of equipment procurement and tooling storage, and simplifies the layout of on-site material transfer equipment.

[0062] The single base frame 203 is equipped with four independent chambers, forming four clamping spaces that can operate synchronously. It can clamp multiple profiles simultaneously to complete batch transfer, which significantly improves the efficiency of profile storage, retrieval and transfer operations compared with single-slot handling mechanisms, and is suitable for automated inbound and outbound operations of large batches of profiles in warehouses.

[0063] The lateral adjustment structure 201 relies on the telescopic drive component 2013 to drive the sliding seat 2012, which can precisely and steplessly adjust the clamping space and clamping width to adapt to profiles of different widths. It can avoid the profile slipping due to excessively loose clamping and the surface extrusion damage caused by excessively tight clamping. The clamping adaptation range is wider and the clamping stability is higher. The transmission screw 2015 is used in conjunction with the transmission connecting rod 2017 to deflect the side baffle 2011. The adjustment accuracy is high and the self-locking is strong. The two side baffles 2011 can be symmetrically tilted to form a trapezoidal adaptation slot, which perfectly fits the inclined side of the trapezoidal profile. At the same time, the flexible connector 204 can seal the adjustment gap to prevent the edge of the profile from getting stuck in the gap of the mechanism. The operation is smooth and without jamming, and the fitting and positioning effect of irregular profiles is excellent.

[0064] The bottom adjustment structure 202 can independently adjust the support height of the bottom support 2021. The arc-shaped groove 2023 in the middle of the bottom support 2021 can limit the cylindrical profile to prevent rolling. When working with sheet metal and square tubes, the bottom support 2021 can be lowered to be held by the side baffle 2011, so as to achieve differentiated bottom support for different profiles and avoid the problems of rolling deviation of round profiles and deformation of thin plates when suspended and clamped.

[0065] The system adopts a composite motion mode of gantry frame 101 for horizontal movement and lifting drive unit 104 for vertical lifting. It can quickly complete the transfer and alignment of profiles between different stacking heights and different workstations. The movement and lifting actions are smoothly linked, with a high degree of automation. No manual assistance is required for handling, reducing the intensity of manual labor and improving the level of automation in the warehousing system.

[0066] Each chamber's adjustment structure is independently controllable, allowing for single-chamber or multi-chamber synchronous operation depending on the material stacking conditions on site, providing a flexible operating mode. The entire mechanical adjustment mechanism does not require complex electrical control identification modules; it relies on the mechanical structure to adaptively deform and adapt to the profile shape, resulting in a low failure rate, simple maintenance, and suitability for long-term continuous warehousing and transfer operations.

[0067] Specifically, such as Figure 1 As shown, the storage system of the present invention also includes a storage device 4 and a transfer device 5. The cantilever storage method allows the profiles to be stored in layers and according to specifications and categories. Materials of different lengths can be stored through the material frame. Rectangular profiles, cylindrical profiles, trapezoidal profiles and plate profiles are respectively arranged on the corresponding different storage devices 4. The transfer device 5 is used to transport goods and send them out or in.

[0068] Working Principle: This system is equipped with a storage device 4 and a transfer device 5, which, together with a gantry conveying mechanism, complete the automated storage and loading / unloading of profiles through classification, layering, and partitioning. The storage device 4 adopts a cantilevered storage structure with layered storage space, enabling the orderly stacking of multiple layers of profiles and preventing deformation due to stacking and compression. It also allows for partitioned and categorized storage based on profile specifications and types. With the auxiliary adaptation of the matching material frames, the storage device 4 can accommodate various profiles of different lengths, effectively solving the problems of mixed and disorganized storage of profiles of varying lengths and limited capacity.

[0069] This invention employs a cantilevered layered storage device 4 structure, enabling the orderly storage of profiles in layers, zones, and categories. This effectively avoids problems such as profile compression deformation, surface scratches, and long-term pressure damage to bottom materials caused by traditional stacking storage, significantly improving the protection effect of profile storage. Simultaneously, the shelving can be adapted to profiles of different lengths and specifications with the material racks, breaking through the limitations of traditional shelving on material length dimensions. It can accommodate profiles of varying lengths in an orderly manner, resulting in stronger storage adaptability and higher warehouse space utilization.

[0070] This invention stores rectangular, cylindrical, trapezoidal, and plate-shaped profiles in designated areas, achieving standardized zoning management based on category, specifications, and form. The materials are neatly and clearly arranged, eliminating mixed storage and facilitating subsequent automated and precise material retrieval and fixed-point warehousing. This effectively reduces the error rate in material sorting and improves the standardization of warehouse management.

[0071] The present invention is equipped with a transfer device 5 as an auxiliary transfer mechanism, which can work with the gantry conveying system to complete the connection and transfer operation of material inbound and outbound feeding, realize the full-process automation of profile inbound, storage and outbound, make up for the limited operating range of the gantry mechanism, make the material transfer connection smoother, greatly improve the inbound and outbound efficiency and operation continuity of the overall warehousing system, reduce the labor intensity of manual handling, and realize the systematic, automated and standardized operation of profile warehousing system.

[0072] It is worth noting that, such as Figures 4 to 7 As shown, the bottom adjustment structure 202 of the present invention further includes an adaptive fitting component, which includes a guide groove 2024, a compensation slider 2025, a return spring 2026, an angle adapter block 2027, a torsion spring 2028, and a follower plate 2029. The four guide grooves 2024 are respectively opened on both sides of the bottom support 2021. The compensation slider 2025 is slidably connected in the guide groove 2024. The return spring 2026 is connected between the guide groove 2024 and the compensation slider 2025. The angle adapter block 2027 is rotatably connected to the head end of the compensation slider 2025. The torsion spring 2028 is connected between the angle adapter block 2027 and the compensation slider 2025, and the torsion spring 2028 is sleeved on the shaft connecting the angle adapter block 2027 and the compensation slider 2025. The follower plate 2029 is installed on the angle adapter block 2027 and is attached to the surface of the side baffle 2011.

[0073] Working principle: The base support 2021 has symmetrical guide grooves 2024 on both sides. The compensation slider 2025 can slide horizontally along the guide grooves 2024. The return spring 2026 always provides an outward pushing elastic preload to the compensation slider 2025. When the side baffles 2011 open and close at different angles or change their tilt angles, the follower plate 2029 always adheres to the inner wall of the side baffle 2011. The tilt change of the side baffle 2011 will push the compensation slider 2025 in the opposite direction to overcome the elastic force of the return spring 2026 and slide inward, automatically adapting to the change in the opening and closing distance of the side baffle 2011. When the side baffle 2011 returns to its original position, the return spring 2026 rebounds and pushes the compensation slider 2025 outward, achieving full-range adaptive sliding compensation without structural jamming or gap-free suspension. The head end of the compensation slider 2025 is rotatably connected to the angle adapter block 2027 via a rotating shaft. A torsion spring 2028 is sleeved on the outside of the rotating shaft. The two ends of the torsion spring 2028 abut against the compensation slider 2025 and the angle adapter block 2027 respectively, so that the angle adapter block 2027 always maintains an elastic deflection tendency toward the side baffle 2011. During operation, the follower plate 2029 rotates slightly adaptively with the angle adapter block 2027, which can fit against the inner wall surface of the side baffle 2011 at different tilt angles in real time. This ensures that the follower plate 2029 can fit tightly against the inner side of the side baffle 2011 regardless of whether the side baffle 2011 is in a vertical or inclined trapezoidal state, eliminating dead angles in the fit. When clamping rectangular, trapezoidal, and plate-shaped profiles, the side follower plates 2029 deform synchronously with the side baffles 2011, forming a fully enclosed support structure with the bottom support 2021, thus improving the lateral limiting effect of the profiles. When clamping cylindrical profiles, the side follower plates 2029, together with the central arc-shaped groove 2023, form a combined limiting structure, further restricting the rolling deviation of the cylindrical tube. The overall structure, through the dual adaptive effects of sliding expansion and contraction compensation and torsional elastic fitting, allows the bottom adjustment structure 202 to match the deformation action of the lateral adjustment structure 201, ensuring that a stable and fitting clamping cavity can be formed after each deformation of the clamping space, greatly improving the stability and versatility of handling various profile types.

[0074] This invention constructs an adaptive fitting component by adding a guide groove 2024, a compensation slider 2025, a return spring 2026, a torsion spring 2028, and an adaptive follow-up plate 2029 to the bottom adjustment structure 202. This effectively coordinates the spacing and angle adjustment actions, solving the defects of traditional deformable clamping structures after angle adjustment, such as fitting gaps, support misalignment, poor adaptability, unstable clamping, and easy loosening and displacement of irregular profiles. It significantly improves the fitting degree, stability, and structural linkage adaptability of clamping and handling profiles of multiple specifications and cross-sections.

[0075] This invention utilizes a return spring 2026 to drive a compensation slider 2025 to adaptively slide and compensate along a guide groove 2024. It can automatically extend and retract to adapt to changes in the opening and closing distance and tilt angle of the side baffles 2011 on both sides, eliminating mechanical gaps throughout the process and avoiding problems such as structural jamming and suspension during angle adjustment. This ensures a continuous, smooth, and uninterrupted deformation process in the clamping space, with high consistency in structural linkage.

[0076] Meanwhile, the torsion spring 2028 provides continuous elastic preload to the angle adapter block 2027 and the follower plate 2029, enabling the follower plate 2029 to adaptively deflect slightly with the change of the tilt angle of the side baffle 2011, always closely fitting the inner wall of the side baffle 2011. This can form all-round fitting support for profiles with different cross-sections such as rectangular, trapezoidal, plate, and cylindrical, completely eliminating the fitting dead angle and local loose clamping problems existing in traditional clamping structures, and effectively improving the clamping envelope and positioning accuracy of the profiles.

[0077] This structure, in conjunction with the arc-shaped groove 2023 of the base support 2021, forms a composite limiting structure with bottom support and lateral adaptive fitting. It can not only prevent rolling of cylindrical profiles, but also achieve full coverage and clamping of irregular profiles and plates. This effectively avoids slippage, loosening, uneven stress, and local compression deformation during profile handling, greatly improving the stability and reliability of general-purpose handling of various profiles, significantly expanding the equipment's adaptability range, and improving the overall operational quality of automated warehousing and transfer of profiles.

[0078] Furthermore, such as Figures 4 to 8 As shown, the frame assembly 2 of the present invention further includes a clamping assembly 3, which includes a pressing contact 304, an arc-shaped force-applying rod 301, a transmission gear 302, and a rotary actuator 303. The pressing contact 304 is installed at the end of the arc-shaped force-applying rod 301, which has an arc-shaped structure and is slidably connected to the side baffle 2011. The rear end of the arc-shaped force-applying rod 301 is meshed with the transmission gear 302, which is installed at the output end of the rotary actuator 303. The rotary actuator 303 is installed on the side baffle 2011.

[0079] Working principle: The rotary actuator 303 is fixedly installed on the side baffle 2011. During operation, the rotary actuator 303 drives the transmission gear 302 to rotate in the forward or reverse direction. Utilizing the meshing transmission relationship between the gear and the arc-shaped force-applying rod 301, stable power is provided for the sliding feed of the arc-shaped force-applying rod 301. The extension and retraction stroke of the arc-shaped force-applying rod 301 can be precisely controlled, realizing controllable adjustment of the clamping force and clamping stroke. The arc-shaped force-applying rod 301 adopts an arc-shaped rod structure and is slidably assembled on the side baffle 2011. It can conform to the changes in the tilt angle of the side baffle 2011 to make arc-shaped sliding displacement, without sliding jamming or movement interference due to different angle states of the side baffle 2011, such as vertical or tilted. The end of the arc-shaped force-applying rod 301 is equipped with a clamping contact 304, which feeds synchronously in an arc shape. It can adaptively conform to the side wall of the profile according to its shape. Compared with the linear clamping assembly 3, it can adapt to the curved and flat clamping requirements of various profiles such as square, trapezoidal, arc, and plate, with a wider range of adaptability. After the deformation adaptation and initial positioning and support of the profile are completed in the clamping space, the rotary actuator 303 is activated. The transmission gear 302 drives the arc-shaped force-applying rod 301 to slide forward, so that the clamping contact 304 presses tightly against the side wall of the profile, and laterally clamps and fixes the profile. Combined with the support of the bottom support 2021 and the adaptive fitting and limiting of the follower plates 2029 on both sides, a multi-directional composite clamping structure is formed, which greatly improves the clamping firmness of the profile. During unloading and reset, the transmission gear 302 rotates in the opposite direction, which drives the arc-shaped force-applying rod 301 and the clamping contact 304 to retract and disengage from the profile, releasing the clamping constraint, and thus successfully completing the unloading of the profile. The clamping component 3 can be adjusted synchronously with the side baffle 2011 angle adjustment, the bottom support 2021 lifting compensation, and the compensation slider 2025 adaptive sliding adjustment, always keeping the clamping direction perpendicular to the side wall of the profile, unaffected by the deformation state of the clamping space. This ensures that the device can achieve precise and stable lateral clamping when clamping cuboid profiles, cylindrical profiles, trapezoidal profiles, and plate profiles, solving the problems of easy loosening and insecure clamping during the transfer of multi-specification irregular profiles.

[0080] This invention integrates an adaptive clamping assembly 3, consisting of a rotary actuator 303, a transmission gear 302, an arc-shaped force-applying rod 301, and a clamping contact 304, onto the side baffle 2011. Relying on gear meshing transmission, the arc-shaped force-applying rod 301 is precisely fed and extended, solving the defects of traditional deformation clamping mechanisms that rely only on passive contact and limit, lack active clamping function, and are prone to loose clamping, poor contact, and easy deviation and shaking during transportation of irregularly shaped profiles and thin plate profiles. This invention further improves the multi-directional composite clamping system and comprehensively enhances the clamping stability of profiles with different cross-sections.

[0081] The arc-shaped force bar 301 adopts an arc-shaped bar structure and is slidably assembled on the side baffle 2011. It can adaptively slide in an arc shape following the vertical and tilted deformation states of the side baffle 2011. There is no motion interference or jamming throughout the process. The clamping stroke and clamping angle can be adapted in real time with the deformation of the clamping space, and the clamping contact 304 is always perpendicular to the side wall of the profile. It completely avoids the problems of traditional linear clamping components 3 being unable to adapt to trapezoidal and arc-shaped profiles and having poor angle adaptability. It is compatible with the lateral clamping and fixing requirements of cuboid profiles, cylindrical profiles, trapezoidal profiles and plate profiles, and has extremely strong universal adaptability.

[0082] This structure employs an independent gear meshing drive, ensuring high transmission precision and excellent self-locking. It precisely controls the feed stroke and clamping force of the arc-shaped force-applying rod 301, achieving controllable active clamping. This prevents insufficient clamping force from causing the profile to loosen during transport, while also preventing excessive pressure from damaging the profile surface, ensuring uniform and controllable clamping force. Simultaneously, the clamping component 3 can work synchronously with the spacing adjustment, angle adjustment, and lifting adaptive compensation structure. Combined with the bottom support 2021 and the lateral follower plate 2029's adaptive limiting, it forms a comprehensive, multi-dimensional composite clamping and fixing structure, completely eliminating the problems of offset, loosening, and detachment during profile transport, significantly improving the stability, safety, and operational accuracy of profile storage and transport.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
