Description

Technical Field

[0001] This utility model relates to the technical field of HVAC duct spraying support device, and in particular to HVAC duct external pipe surface spraying support device. Background Technology

[0002] HVAC ductwork outer pipes and their surface sprayed support devices provide stable support and protection for the pipelines, ensuring their safety and durability during operation. The protective coating improves the pipeline's corrosion resistance, extends its service life, and effectively prevents damage from external factors.

[0003] Traditional pipe surface spraying support devices typically consist of a support frame, fixing components, and adjustment mechanisms. These components work together to support the pipe and maintain its stability, ensuring that the pipe is not easily displaced or deformed during the spraying process, thereby ensuring the uniformity and durability of the spraying effect.

[0004] Traditional pipe coating support devices, due to their fixed support and adjustment design, cannot automatically adjust the support strength or position according to changes in pipe size. Therefore, when the pipe size changes, traditional devices often cannot provide adequate support, resulting in unstable pipe position, which in turn affects the coating quality or increases device wear and tear. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a support device for spraying HVAC pipe surfaces, which aims to improve the problem that traditional pipe surface spraying support devices cannot provide adequate support, resulting in unstable pipe positions, which in turn affects the spraying quality or increases the wear and tear of the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a support device for spraying coating on the outer surface of HVAC ducts, comprising multiple fixed platforms, each fixed platform having a side platform on its side wall, a side plate being fixedly connected to both the fixed platform and the side platform side wall, a rotating frame being rotatably connected inside each side plate, a connecting shaft being provided between the multiple rotating frames, the multiple rotating frames being rotatably connected to the outer wall of the connecting shaft, and a support assembly being provided on the side wall of the side platform.

[0007] The support assembly includes multiple fixing plates, which are fixedly connected to each side wall of the side platform. Each side wall of the side platform is rotatably connected to multiple rubber wheels. A spring is provided between the side platform and the fixing platform, with both ends of the spring fixedly connected to the fixing platform and the side wall of the side platform, respectively. A hoisting assembly is provided on the side wall of the fixing platform.

[0008] Furthermore, the hoisting assembly includes multiple hoisting rods and hoisting plates, with the sidewalls of the multiple hoisting plates respectively fixedly connected to the sidewall of each fixed platform, and each sidewall of the hoisting plate being fixedly connected to a hoisting rod.

[0009] Furthermore, a platform is fixedly connected to the top of the boom, and a fixing frame is fixedly connected to the side wall of the platform.

[0010] Furthermore, a motor is fixedly connected to the side wall of the fixed frame, and an output shaft is fixedly connected to the output end of the motor.

[0011] Furthermore, multiple side wheels are fixedly connected to the outer wall of the output shaft, and a base is fixedly connected to the lower surface of the lifting platform.

[0012] Furthermore, multiple sliders are slidably connected inside the base, and each slider has a bottom wheel rotatably connected to its lower surface.

[0013] Furthermore, multiple additional side wheels are rotatably connected to the other side of the platform, and a second spring is installed inside the base.

[0014] Furthermore, the two ends of the spring are respectively fixedly connected to the side walls of the multiple sliders.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the outer wall of the pipe first pushes the side platform to move towards the fixed platform. The elastic potential energy of the spring pushes the side platform to support the pipe, thereby achieving self-adaptation to the pipe specifications, effectively improving the stability of the pipe during the spraying process, avoiding displacement or deformation of the pipe due to insufficient support, and thus ensuring the consistency and uniformity of the spraying quality.

[0017] 2. In this utility model, the output shaft is driven by a motor to rotate the side wheels. Finally, the sliding of the slider inside the base and the elastic reset of the spring allow the distance between the bottom wheels to be adjusted according to the width of the slide rail. This provides convenience for the positioning, installation, disassembly and adjustment of the pipeline. Especially when dealing with larger or heavier pipelines, the hoisting system can effectively reduce the complexity and labor intensity of manual operation, making the movement and adjustment of the pipeline more efficient and precise.

[0023] 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.

[0024] Reference Figures 1-2 This utility model provides an embodiment of a HVAC duct external surface spraying support device, comprising multiple fixed platforms 1, each fixed platform 1 having a side platform 3 on its side wall. The side platform 3 provides necessary support force during duct support. Side plates 5 are fixedly connected to the side walls of both the fixed platforms 1 and the side platforms 3, reinforcing and stabilizing the side platforms 3 to ensure no loosening during operation. A rotating bracket 6 is rotatably connected inside each side plate 5. A connecting shaft 2 is provided between the multiple rotating brackets 6, and the multiple rotating brackets 6 are rotatably connected to the outer wall of the connecting shaft 2. The connecting shaft 2 provides the rotation axis of the rotating brackets 6 and ensures the smoothness of rotation. Support components are provided on the side walls of the side platforms 3, and the support components are reinforced by fixed plates 7. The fixed plates 7 are fixedly connected to each side platform 3. Each side platform 3 provides uniform support to maintain the stability of the pipeline. Each side platform 3 is rotatably connected to multiple rubber wheels 4, which can slide on the pipeline surface, reducing friction and ensuring smooth movement of the support device, avoiding damage to the pipeline surface. A spring 8 is installed between the side platform 3 and the fixed platform 1. The two ends of the spring 8 are fixedly connected to the fixed platform 1 and the side platform 3, respectively. The spring 8 can adjust the position of the side platform 3 according to the weight of the pipeline through its elasticity, further increasing the stability and adaptability of the support. The side wall of the fixed platform 1 is equipped with a hoisting assembly, which provides support for the hoisting of the pipeline, ensuring that the pipeline can be stably suspended during the spraying process, thereby improving the overall working efficiency of the device and the accuracy of the pipeline spraying process.

[0025] Specifically, firstly, when the pipe needs to be supported and fixed, the pipe is placed between multiple fixed platforms 1. The outer wall of the pipe pushes the side platform 3, causing the side platform 3 to shift towards the fixed platform 1. Multiple rotating brackets 6 rotate inside the side plate 5, and change their tilt angle during the rotation to adapt to the support requirements of the pipe. Subsequently, the elastic potential energy of the spring 8 pushes the side platform 3, so that the fixed plate 7 effectively supports the pipe, ensuring that the pipe can receive uniform support force at different positions, thereby achieving adaptive adjustment of pipe specifications. This process can significantly improve the stability of the pipe during the spraying process, avoid displacement or deformation of the pipe due to insufficient support, and thus effectively ensure the consistency and uniformity of quality during the spraying process.

[0026] Reference Figure 3 The hoisting assembly includes multiple lifting rods 9 and lifting plates 10. The side walls of the multiple lifting plates 10 are respectively fixedly connected to the side walls of each fixed platform 1. Each side wall of the lifting plate 10 is fixedly connected to a lifting rod 9. The top of the lifting rod 9 is fixedly connected to a lifting platform 11. The side wall of the lifting platform 11 is fixedly connected to a fixed frame 12. The side wall of the fixed frame 12 is fixedly connected to a motor 13. The output end of the motor 13 is fixedly connected to an output shaft 14. The outer wall of the output shaft 14 is fixedly connected to multiple side wheels 15. The lower surface of the lifting platform 11 is fixedly connected to a base platform 16. Multiple sliders 17 are slidably connected inside the base platform 16. The lower surface of each slider 17 is rotatably connected to a base wheel 18. The other side of the lifting platform 11 is rotatably connected to multiple other side wheels 15. The base platform 16 is equipped with a second spring 19. The two ends of the second spring 19 are respectively fixedly connected to the side walls of the multiple sliders 17.

[0027] Specifically, when the pipeline needs to be hoisted, the motor 13 is first started. The motor 13 drives the output shaft 14 to rotate, which in turn drives the side wheel 15 to rotate. The rotation of the side wheel 15 further causes the hoisting platform 11 to move along the top direction of the slide rail. At the same time, the multiple bottom wheels 18 also slide synchronously on the side wall of the slide rail, thereby ensuring the stability of the pipeline during hoisting. During this process, the slider 17 slides inside the base platform 16, and through the elastic reset action of the spring 19, the distance between the bottom wheels 18 can be appropriately adjusted according to the width of the slide rail. This adjustment function provides great convenience for the positioning, installation, disassembly and adjustment of the pipeline. Especially when dealing with larger or heavier pipelines, it can effectively reduce the complexity and labor intensity of manual operation, further improve the efficiency of pipeline movement and adjustment, and make the whole process more efficient and precise.

[0028] Working principle: When the pipe needs to be supported and fixed, it is placed between multiple fixed platforms 1. The outer wall of the pipe pushes the side platform 3, causing it to move towards the fixed platform 1. Multiple rotating frames 6 rotate inside the side plate 5 and change their tilt angle. Then, the elastic potential energy of the spring 8 pushes the side platform 3, causing the fixed plate 7 to support the pipe, achieving self-adaptation to pipe specifications. This effectively improves the stability of the pipe during the spraying process, preventing displacement or deformation due to insufficient support, thus ensuring the consistency and uniformity of the spraying quality. When the pipe needs to be hoisted, the motor 13 is started. The output shaft 14 causes the side wheel 15 to rotate, which in turn drives the lifting platform 11 to move at the top of the slide rail. Simultaneously, the multiple bottom wheels 18 also slide on the side wall of the slide rail to ensure the stability of the pipe hoisting. At the same time, the sliding of the slider 17 inside the base 16 and the elastic reset of the spring 19 allow the distance between the bottom wheels 18 to be adjusted according to the width of the slide rail, which facilitates the positioning, installation, disassembly and adjustment of the pipe. Especially when dealing with larger or heavier pipes, the hoisting system can effectively reduce the complexity and labor intensity of manual operation, making the movement and adjustment of the pipe more efficient and precise.
