Description

Technical Field

[0001] This application relates to the field of lifting equipment technology, specifically a novel anti-deformation spray coating lifting equipment. Background Technology

[0002] In the sheet metal processing industry, product deformation has long been a problem in the painting process of large-area thin sheet products such as roof panels and wall panels. With the advancement of the global trend of vehicle lightweighting, these products generally use thin sheet materials (usually ≤3mm thick). After processing such as bending and rolling, although the lightweight requirements are met, the rigidity of the sheet material is significantly reduced. During the painting process, the product needs to be suspended and fixed by a hoist. However, when large thin panels are suspended, their own weight causes the middle area to sag, resulting in stress concentration. After powder coating, they need to be cured at a high temperature of about 200°C. The thermal expansion effect further aggravates the deformation of the panels. Traditional hanging tools mostly use point suspension (such as hooks and claws), which have a small contact area and excessive local pressure, easily causing indentations or deformation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides a novel anti-deformation spraying hanger, which has advantages such as anti-deformation and solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a novel anti-deformation spraying hanger, comprising a supporting profile and clamping profiles disposed at both ends of the supporting profile, wherein the supporting profile and the two clamping profiles are arranged in a U-shaped structure, and the ends of the two clamping profiles near the supporting profile are connected by corner joints; The supporting profile includes a fixed rail, and two lead screws are provided at the bottom of the fixed rail along its length. The close ends of the two lead screws are rotatably connected to the side wall of the fixed rail, and extension blocks are threaded to the outer surfaces of the two lead screws. Both extension blocks are slidably connected to the fixed rail. The clamping profile includes a limiting side frame, a threaded rod is rotatably connected between the inner top wall and the inner bottom wall of the limiting side frame, a lifting block is threadedly connected to the outer surface of the threaded rod, the lifting block is slidably connected to the limiting side frame, and a clamping mechanism is provided at one end of the lifting block.

[0005] Furthermore, the corner connector includes a bearing seat, one end of which is fixedly connected to the bearing seat and its corresponding extension block. An angle shaft is rotatably connected between the two inner walls of the bearing seat. A flip plate is fixedly connected to the outer surface of the angle shaft. The other end of the flip plate is fixedly connected to one end of its corresponding limiting side frame.

[0006] The above solution involves rotating the angle axis (e.g., by a motor drive) to rotate the flip plate and clamping profile around the shaft seat, thereby adjusting the angle between the clamping profile and the supporting profile, which is suitable for vertical clamping of flat top plates or fitting and fixing of curved top plates.

[0007] Furthermore, one end of the angle shaft is fixedly connected to the output end of an external power source.

[0008] With the above solution, the power source can be installed on one side of the shaft plate. The power source can be a servo motor or a pneumatic motor. By setting the power source, the angle of the clamping profile can be adjusted.

[0009] Furthermore, the shaft seat and the extension block are fixedly connected by bolts, and one end of the flip plate is fixedly connected to one end of the limiting side frame by bolts.

[0010] The above solution enables modular connection between corner joints, supporting profiles, and clamping profiles, facilitating quick disassembly and maintenance.

[0011] Furthermore, the clamping mechanism includes a shaft plate, which is fixedly connected to its corresponding lifting block. A clamping shaft is rotatably connected between the two inner sidewalls of the shaft plate. An L-shaped plate is fixedly connected to the outer surface of the clamping shaft. A fixing plate is fixedly connected to one side of the L-shaped plate. A cylinder is fixedly installed on the fixing plate along the axis of the L-shaped plate. A clamping plate is fixedly connected to the output end of the cylinder.

[0012] The above method allows for clamping and fixing of the top plate edge by using a cylinder to drive the clamping plate closer to the bottom of the L-shaped plate.

[0013] Furthermore, one end of the clamping shaft is fixedly connected to the output end of an external power source.

[0014] With the above solution, the power source can be installed on one side of the shaft plate to achieve precise adjustment of the L-shaped plate clamping angle and adapt to the tilt angle of different top plate edges.

[0015] Furthermore, the bottom end of the threaded rod is fixedly connected to the output end of an external power source.

[0016] The above solution enables the adjustment of the height of the lifting block and clamping mechanism.

[0017] Furthermore, a power box is fixedly connected to the bottom of the supporting profile, and a power shaft with an axis perpendicular to the lead screw is rotatably connected to the power box. One end of the power shaft is connected to one end of the two lead screws through a bevel gear transmission, and one end of the power shaft is fixedly connected to the output end of an external power source.

[0018] The above scheme uses a servo motor to drive the power shaft to rotate, which in turn drives the two lead screws to rotate synchronously via bevel gears, thereby adjusting the width of the extension block and support. The bevel gear transmission ensures the synchronicity of the lead screws on both sides, avoiding inconsistent displacement of the extension blocks on both sides during width adjustment.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects: This new type of anti-deformation spraying hanger, through the design of U-shaped structure support profile and clamping profile, realizes the clamping and support of the top plate, avoids the problem of local stress concentration caused by traditional point suspension, and effectively reduces the contour deformation problem caused by self-weight sagging and high temperature curing thermal expansion during the spraying process. The sliding adjustment mechanism of the extension block driven by the screw in the support profile enables rapid adaptation in the width direction of the lifting device. The support range can be flexibly adjusted according to the width of different roof panels, which significantly improves the compatibility of the lifting device with products of multiple specifications. The rotation adjustment function of the flip plate driven by the angle shaft in the corner connector enables dynamic adjustment of the angle between the clamping profile and the support profile, allowing the lifting device to fit the edge contour of irregularly shaped roof panels such as arcs and bends, thus expanding the range of applicable product shapes. The coordinated clamping structure of the cylinder-driven clamping plate and the L-shaped plate is used to fix the edge of the top plate, preventing the top plate from falling or shaking during the movement of the lifting device, thus ensuring the appearance quality after spraying. The design of the bearing seat, flip plate, and bolt fixing method enables quick disassembly and maintenance of components. When a component is damaged or deformed, it is easy to replace it individually, further enhancing the maintainability of the lifting tool. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figures 1-6 This embodiment of a novel anti-deformation spraying hanger includes a supporting profile 1 and clamping profiles 2 at both ends of the supporting profile 1. The supporting profile 1 and the two clamping profiles 2 are arranged in a U-shape. The supporting profile 1 can support the weight of the top plate. The surface contact design of the U-shape structure evenly disperses the stress generated by the self-weight of the top plate, avoiding the local sagging deformation caused by traditional point suspension. The two clamping profiles 2 are connected by corner joints 3 at the ends closest to the supporting profile 1. The angle between the clamping profiles 2 and the supporting profile 1 can be adjusted by the corner joints 3, thus making it suitable for fixing the edges of top plates of different shapes such as flat, curved, bent or sized.

[0024] The corner connector 3 includes a bearing seat 301, which is fixedly connected to one end of its corresponding extension block 103. An angle shaft 302 is rotatably connected between the two inner walls of the bearing seat 301. A flip plate 303 is fixedly connected to the outer surface of the angle shaft 302. The other end of the flip plate 303 is fixedly connected to one end of its corresponding limiting side frame 201. By driving the angle shaft 302 to rotate, such as by a motor, the flip plate 303 and the clamping profile 2 are driven to rotate around the bearing seat 301, thereby adjusting the angle between the clamping profile 2 and the supporting profile 1. This is suitable for vertical clamping of flat top plates or fitting and fixing of curved top plates. One end of the angle shaft 302 is fixedly connected to the output end of an external power source. The power source can be installed on one side of the shaft plate 401. The power source can be a servo motor or a pneumatic motor. By setting the power source, the angle of the clamping profile 2 can be adjusted.

[0025] The support profile 1 includes a fixed rail 101. Two lead screws 102 are provided at the bottom of the fixed rail 101 along its length. The close ends of the two lead screws 102 are rotatably connected to the side wall of the fixed rail 101. Extension blocks 103 are threadedly connected to the outer surfaces of the two lead screws 102. Both extension blocks 103 are slidably connected to the fixed rail 101. By rotating the lead screws 102 forward / reverse, the extension blocks 103 are driven to slide synchronously outward or inward along the length of the fixed rail 101, thereby adjusting the effective support width of the support profile 1 to match the support requirements of roof plates of different widths.

[0026] The clamping profile 2 includes a limiting side frame 201. A threaded rod 202 is rotatably connected between the inner top wall and the inner bottom wall of the limiting side frame 201. A lifting block 203 is threadedly connected to the outer surface of the threaded rod 202. The lifting block 203 is slidably connected to the limiting side frame 201. A clamping mechanism 4 is provided at one end of the lifting block 203. By rotating the threaded rod 202 in forward / reverse direction, the lifting block 203 is driven to vertically rise and fall along the limiting side frame 201, thereby adjusting the height position of the clamping mechanism 4 to match the clamping requirements of top plates of different thicknesses. The clamping mechanism 4 includes a shaft plate 401. The shaft plate 401 is fixedly connected to its corresponding lifting block 203. A clamping shaft 402 is rotatably connected between the two inner side walls of the shaft plate 401. An L-shaped plate 403 is fixedly connected to the outer surface of the clamping shaft 402. A fixing plate 404 is fixedly connected to one side of the L-shaped plate 403. A cylinder 405 is fixedly installed on the fixing plate 404 along the axis of the L-shaped plate 403. A clamping plate 406 is fixedly connected to the output end of the cylinder 405. The cylinder 405 drives the clamping plate 406 to move closer to the bottom of the L-shaped plate 403, thereby achieving clamping and fixing of the edge of the top plate.

[0027] The bottom end of the threaded rod 202 is fixedly connected to the output end of an external power source, enabling height adjustment of the lifting block 203 and the clamping mechanism 4. One end of the clamping shaft 402 is fixedly connected to the output end of an external power source. The power source can be installed on one side of the shaft plate 401, enabling precise adjustment of the clamping angle of the L-shaped plate 403 to adapt to the tilt angle of different top plate edges. The shaft seat 301 and the extension block 103 are fixedly connected by bolts. One end of the flip plate 303 is fixedly connected to one end of the limiting side frame 201 by bolts, realizing modular connection of the corner connector 3 with the supporting profile 1 and the clamping profile 2, facilitating quick and easy connection. For quick assembly and maintenance, a power box 5 is fixedly connected to the bottom of the support profile 1. The power box 5 is rotatably connected to a power shaft 6 whose axis is perpendicular to the lead screw 102. One end of the power shaft 6 is connected to one end of the two lead screws 102 via a bevel gear transmission. One end of the power shaft 6 is fixedly connected to the output end of an external power source. The power shaft 6 is driven to rotate by a servo motor, which synchronously drives the two lead screws 102 to rotate via the bevel gear, thereby realizing the adjustment of the extension block 103 and the support width. The bevel gear transmission ensures the synchronicity of the lead screws 102 on both sides and avoids inconsistent displacement of the extension block 103 on both sides when adjusting the width.

[0028] The working principle of the above embodiment is as follows: The servo motor in the power box 5 drives the power shaft 6 to rotate, which synchronously drives the lead screws 102 on both sides to rotate through the bevel gear set. The two lead screws 102 have opposite thread directions. When rotating, the extension block 103 is driven to slide in opposite directions along the fixed rail 101 to realize the width adjustment of the support profile 1. The threaded rod 202 in the clamping profile 2 is driven to rotate by the servo motor, which drives the lifting block 203 to rise and fall vertically along the limit side frame 201. The lifting block 203 drives the clamping mechanism 4 to move synchronously to realize the adjustment of the clamping point height. The angle shaft 302 in the corner connector 3 is driven to rotate by the servo motor, which drives the flip plate 303 and the clamping mechanism 4 to rotate. Profile 2 rotates around the bearing 301, allowing the clamping profile 2 to be fixed to the vertical plane top plate or the inclined arc / bent top plate, ensuring that the lifting device is completely in contact with the edge of the top plate. The L-shaped plate 403 in the clamping mechanism 4 rotates and adjusts its angle through the clamping shaft 402 to match the inclination of the top plate edge. The cylinder 405 drives the clamping plate 406 to move towards the bottom of the L-shaped plate 403, forming a clamping force on the edge of the top plate, preventing the top plate from sliding during the spraying or hoisting process. The U-shaped support profile 1 supports the top plate through surface contact, dispersing the self-weight stress and avoiding the local pressure marks of traditional point suspension. The clamping points are distributed on both sides of the top plate edge, forming a symmetrical fixation to ensure hoisting stability.
