Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a multi-faceted powder coating device for steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Their structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Due to the advantages of steel structures such as high strength, light weight and fast construction speed, they are widely used in the fields of construction, bridges, and machinery manufacturing. However, steel structures often require surface coating treatment during processing to improve their corrosion resistance, durability and aesthetics.

[0003] After installation, H-beam columns usually need to be powder coated to enhance their corrosion resistance, durability and aesthetics. Currently, most powder coating is done manually. When powder coating is done manually, it is necessary to spray in a circle along the outer wall of the H-beam, which makes the labor intensity of the operators high.

[0004] To address the aforementioned problems, this utility model document proposes a multi-faceted powder coating device for steel structures. Utility Model Content

[0005] This utility model provides a multi-faceted powder coating device for steel structures, which solves the problem that in the prior art, H-beam columns usually need to be powder coated after installation to enhance their corrosion resistance, durability and aesthetics. Currently, most powder coating methods are manual, which requires spraying around the outer wall of the H-beam, resulting in high labor intensity for operators.

[0006] This utility model provides the following technical solution:

[0007] A multi-faceted powder coating device with a steel structure includes a base plate, a plurality of casters fixedly connected to the bottom of the base plate, a powder box fixedly connected to the top of the base plate, a cover plate hinged to the top of the powder box, and an observation window opened on one side of the powder box.

[0008] The full-coverage spraying mechanism is located on one side of the base plate and is used to spray powder onto the entire object to be coated.

[0009] In one possible design, the full-coverage spraying mechanism includes a powder pump, a discharge pipe, a diverter pipe, a main material frame, a secondary material frame, and spray nozzles. The bottom of the powder pump is fixedly connected to the top of the base plate. One end of the discharge pipe is fixedly connected to the output end of the powder pump, and the other end of the discharge pipe is fixedly connected to the top of the main material frame. One end of the diverter pipe is fixedly connected to the outer wall of the discharge pipe, and the other end of the diverter pipe is fixedly connected to the top of the secondary material frame. The outer wall of the secondary material frame is hinged to the outer wall of the main material frame. Multiple spray nozzles are respectively fixedly connected to the inner walls of the main material frame and the secondary material frame.

[0010] In one possible design, magnets are fixedly connected to the sides of the main material frame and the auxiliary material frame that are close to each other, with one side of one magnet tightly attached to the side of the other magnet, and the input end of the powder pump is fixedly connected to a feed pipe, the other end of which is fixedly connected to one side of the powder box.

[0011] In one possible design, a lifting frame is fixedly connected to the top of the base plate. The lifting frame has a lifting groove inside, and a lifting block is slidably connected inside the lifting groove. The top of the lifting block is fixedly connected to the top of the main material frame. A motor is fixedly connected to one side of the lifting frame. A first threaded screw is fixedly connected to the output end of the motor. The other end of the first threaded screw is rotatably connected to the top of the base plate. The internal thread of the lifting block is connected to the outer wall of the first threaded screw. Two hollow steel pipes are fixedly connected to one side of the lifting frame to enhance the stability of the lifting frame.

[0012] In one possible design, a constraint frame is fixedly connected to the top of the base plate. The inner walls of both sides of the constraint frame are provided with grooves, and the same extrusion block is slidably connected in the two grooves. A second threaded rod is rotatably connected to the top of the extrusion block. The outer wall of the second threaded rod is threadedly connected to the top side of the constraint frame. One end of the second threaded rod passes through the inner wall of the top side of the constraint frame and is fixedly connected to a rotating handle. A threaded hole is provided on one side of the constraint frame, and a bolt is threadedly connected in the threaded hole. One end of the bolt abuts against the outer wall of the second threaded rod.

[0013] In one possible design, a device frame is fixedly connected to the top of the base plate. Insertion slots are provided on both inner walls of the device frame, and insertion strips are inserted into each slot. A common lifting frame is fixedly connected between the two insertion strips. A battery is installed inside the lifting frame. A controller is fixedly connected to one side of the device frame. The controller is electrically connected to the powder pump, motor, and battery. A steel frame is fixedly connected to the top of the base plate, and two push-pull handles are fixedly connected to one side of the steel frame.

[0014] In this application, during use, the device is moved to the construction site, the magnets between the main and auxiliary material frames are pried open, and the I-beam or other object to be powder-coated is placed between the main and auxiliary material frames. Next, the operator opens the cover of the powder box, pours an appropriate amount of powder into the powder box, and monitors the remaining powder level through the observation window. Then, the operator starts the powder pump, which draws powder from the powder box through the inlet pipe and delivers it to the main material frame through the outlet pipe. Simultaneously, some powder is also delivered to the auxiliary material frame through the diversion pipe. Multiple nozzles within the two frames then evenly spray the powder onto the surface of the object. Because magnets are installed on the near sides of both the main and auxiliary material frames, they remain tightly fitted during spraying, ensuring the stability of the connection between the main and auxiliary material frames. To adjust the spraying height, the operator can start the motor. The rotation of the motor drives the first threaded screw to rotate, and the lifting block, due to its internal thread matching the outer wall of the first threaded screw... The device moves up and down along the lifting trough, causing the main and auxiliary material frames to move accordingly, thus adjusting the spraying height. During spraying, the battery provides power to the entire device, while the controller allows the operator to adjust parameters such as the powder pump power and motor speed as needed. After spraying, the operator can turn off the powder pump and motor, and then easily remove the battery for charging or replacement via the lifting frame. Simultaneously, the device is equipped with multiple casters at the bottom, allowing the operator to easily move it to the next work location. Before this, the constraint frame on the base plate can be used to clamp and constrain the discharge pipe, preventing it from getting tangled in debris at the work site. Turning the handle of the second threaded screw causes the screw to push the extrusion block along the chute, thereby adjusting the extrusion block in the constraint frame to fix the discharge pipe, thus tightening or loosening the constraint on the discharge pipe. To further enhance stability, the second threaded screw can be locked by tightening the bolts on one side of the equipment frame.

[0015] In this utility model, the multi-faceted powder coating device for steel structures, through the comprehensive coating mechanism, can achieve the effect of quickly and evenly spraying powder material onto all surfaces of the steel structure, thereby greatly improving coating efficiency, shortening the coating cycle, and reducing the labor intensity of manual labor.

[0016] In this utility model, the multi-faceted powder coating device with steel structure can be powered by a storage battery, thus enabling it to be compatible with some construction sites lacking electricity and enhancing the practicality of the device.

[0017] In this invention, the comprehensive spraying mechanism ensures uniform spraying of multiple surfaces of the steel structure, improving spraying efficiency and coating quality. At the same time, through structures such as lifting frames and constraint frames, the adaptability and flexibility of the device are enhanced, enabling it to meet the spraying needs of steel structures of different shapes, sizes and heights. Its portable design and easy maintenance further enhance the practicality and durability of the device. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please refer to Figures 1-5A multi-sided powder coating device includes: a base plate 1, a plurality of casters fixedly connected to the bottom of the base plate 1, a powder box 2 fixedly connected to the top of the base plate 1, a cover plate 3 hinged to the top of the powder box 2, and an observation window opened on one side of the powder box 2 for easy observation of the situation inside the powder box 2, so that an appropriate amount of powder material can be poured into the powder box 2.

[0028] A comprehensive spraying mechanism, located on one side of the base plate 1, is used to comprehensively spray powder onto the object to be sprayed. The comprehensive spraying mechanism includes a powder pump 5, a discharge pipe 6, a diversion pipe 7, a main material frame 8, a secondary material frame 9, and a spray nozzle 10. The bottom of the powder pump 5 is fixedly connected to the top of the base plate 1. One end of the discharge pipe 6 is fixedly connected to the output end of the powder pump 5, and the other end is fixedly connected to the top of the main material frame 8. One end of the diversion pipe 7 is fixedly connected to the outer wall of the discharge pipe 6, and the other end is fixedly connected to the main material frame 8. The auxiliary material frame 9 is fixedly connected to the top of the auxiliary material frame 9, and the outer wall of the auxiliary material frame 9 is hinged to the outer wall of the main material frame 8. Multiple nozzles 10 are fixedly connected to the inner walls of the main material frame 8 and the auxiliary material frame 9, respectively. When the operator starts the powder pump 5, the powder pump 5 draws powder material from the powder box 2 through the feed pipe 4 and delivers it to the main material frame 8 through the discharge pipe 6. At the same time, a portion of the powder is also delivered to the auxiliary material frame 9 through the diversion pipe 7. Then, the multiple nozzles 10 in the two frames will evenly spray the powder onto the surface of the object.

[0029] This application can be used in the field of steel structure technology, or in other fields applicable to this application.

[0030] The specific model of powder pump 5 is QBY3-50L, and its structure and mechanism will not be described in detail here;

[0031] Example 2

[0032] Based on Example 1, the following improvements were made:

[0033] A multi-faceted powder coating device for steel structures, which is applied to the field of steel structure technology, including:

[0034] Magnets 11 are fixedly connected to the sides of the main material frame 8 and the auxiliary material frame 9 that are close to each other. One side of one magnet 11 is tightly attached to the side of the other magnet 11. Since the magnets 11 have opposite magnetic properties, they can remain tightly attached during the spraying process, thereby ensuring the stability of the connection between the main material frame 8 and the auxiliary material frame 9. When it is necessary to place an object between the main material frame 8 and the auxiliary material frame 9, it is easy to pry it apart from the position of the two magnets 11, which improves the practicality of the device. The input end of the powder pump 5 is fixedly connected to the feed pipe 4, and the other end of the feed pipe 4 is fixedly connected to one side of the powder box 2, thus providing a basis for the spraying of the device.

[0035] A lifting frame 13 is fixedly connected to the top of the base plate 1. The lifting frame 13 has a lifting groove inside, and a lifting block 12 is slidably connected in the lifting groove. The top of the lifting block 12 is fixedly connected to the top of the main material frame 8. A motor 14 is fixedly connected to one side of the lifting frame 13. A first threaded screw 15 is fixedly connected to the output end of the motor 14. The other end of the first threaded screw 15 is rotatably connected to the top of the base plate 1. The internal thread of the lifting block 12 is connected to the outer wall of the first threaded screw 15. Two hollow steel pipes 16 are fixedly connected to one side of the lifting frame 13 to enhance the stability of the lifting frame 13. When it is necessary to adjust the spraying height, the operator can start the motor 14. The rotation of the motor 14 will drive the first threaded screw 15 to rotate. Since the internal thread of the lifting block 12 matches the outer wall of the first threaded screw 15, it will move up and down along the lifting groove. In this way, the main material frame 8 and the auxiliary material frame 9 will also move up and down, thereby realizing the adjustment of the spraying height.

[0036] A constraint frame 17 is fixedly connected to the top of the base plate 1. Slide grooves are provided on both inner walls of the constraint frame 17, and the same extrusion block 19 is slidably connected within the two slide grooves. A second threaded rod 18 is rotatably connected to the top of the extrusion block 19. The outer wall of the second threaded rod 18 is threadedly connected to the top side of the constraint frame 17. One end of the second threaded rod 18 passes through the inner wall of the top side of the constraint frame 17 and is fixedly connected to a rotating handle. A threaded hole is provided on one side of the constraint frame 17, and a bolt is threadedly connected within the threaded hole. One end of the bolt abuts against the second threaded rod. On the outer wall of the lead screw 18, the constraint frame 17 can be used to clamp and constrain the discharge pipe 6 to prevent it from getting tangled in the debris on the construction site. By rotating the handle of the second threaded lead screw 18, the rotation of the second threaded lead screw 18 will push the extrusion block 19 to slide along the slide groove, thereby adjusting the extrusion block 19 in the constraint frame 17 to fix the discharge pipe 6, thereby tightening or loosening the constraint on the discharge pipe 6. In order to further enhance stability, the second threaded lead screw 18 can be locked by tightening the bolts on one side of the equipment frame 20.

[0037] A device frame 20 is fixedly connected to the top of the base plate 1. Insertion slots are provided on both inner walls of the device frame 20. Insertion strips are inserted into the two insertion slots. A lifting frame 22 is fixedly connected between the two insertion strips. A storage battery 23 is installed inside the lifting frame 22, so that the storage battery 23 can be easily removed for charging or replacement. A controller 21 is fixedly connected to one side of the device frame 20. The controller 21 is electrically connected to the powder pump 5, the motor 14 and the storage battery 23. A steel frame 24 is fixedly connected to the top of the base plate 1. Two push-pull handles are fixedly connected to one side of the steel frame 24, so that the operator can easily move it to the next work location.

[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the powder pump 5, motor 14, controller 21 and battery 23 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.
