Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction technology for building exterior wall insulation layers, specifically to a construction device for building exterior wall insulation layers. Background Technology
[0002] With the growing acceptance of energy-efficient building concepts and increasingly stringent standards, external wall insulation technology, as a core means of reducing building energy consumption, is receiving increasing attention from the industry. Polyurethane materials, with their excellent thermal insulation and waterproof properties, stand out in building external wall insulation projects. The seamless insulation layer formed by on-site spraying effectively eliminates thermal bridging, enhancing building energy efficiency, and is particularly suitable for complex architectural projects.
[0003] Currently, polyurethane spraying for building exteriors mainly relies on two methods: manual operation and purely mechanical spraying. Manual spraying heavily depends on the experience and skills of the workers, resulting in inconsistent spraying quality and difficulty in ensuring uniform insulation layer thickness. Furthermore, working at heights presents a dangerous environment and significant safety risks, making it unsuitable for large-scale, standardized building construction and incurring high safety management costs.
[0004] While purely mechanical spraying improves construction efficiency to some extent, it has significant drawbacks when applied to the exterior walls of high-rise buildings. The vertical height of high-rise building exteriors is considerable, and the lifting mechanisms of traditional mechanical spraying equipment have obvious limitations in terms of load-bearing capacity and range of motion. Because long-distance stable lifting is impossible, construction companies often need to install lifting mechanisms in sections. This not only significantly increases the complexity and cost of equipment installation and debugging, but also leads to frequent disassembly, relocation, and repositioning of the equipment, resulting in low construction efficiency.

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.
[0026] Please see Figure 1-5 This utility model provides a technical solution:
[0027] A construction device for building exterior wall insulation includes two sets of hanging rails 1, with a lifting assembly 2 between the two sets. A lifting platform 3, capable of vertical movement, is mounted on the lifting assembly 2. A power assembly 4, which drives the lifting assembly 2, is located below the lifting assembly 2. A spraying assembly 5 is positioned above the lifting platform 3. The lifting platform 3 can raise or lower the spraying assembly 5 to spray insulation material onto the building exterior wall.
[0028] Furthermore, the hanging rail 1 is a vertical strip, and a guide groove 6 is provided on the inner side of the hanging rail 1. A hoop groove 7 is provided on the side of the guide groove 6 away from the center. A tooth clearance groove 8 is provided on one side of the hoop groove 7. An equidistant tooth hole plate 9 is provided on the other side of the hoop groove 7. Multiple sets of tooth holes 10 are provided on the equidistant tooth hole plate 9.
[0029] Furthermore, the lifting assembly 2 includes a lifting platform 3, a structural housing 11, four sets of guide sliders 12, and two sets of geared discs 13. The structural housing 11 is located below the lifting platform 3. Guide sliders 12 corresponding to guide grooves 6 are provided on both the lifting platform 3 and the structural housing 11. The guide sliders 12 are slidably engaged in the guide grooves 6. Rotatable geared discs 13 are provided on both sides of the structural housing 11. A power assembly 4 for driving the geared discs 13 to rotate is provided inside the structural housing 11.
[0030] Furthermore, the geared disc 13 is provided with multiple sets of climbing teeth 14, which mesh with the tooth holes 10. Limiting discs 15 are provided on both sides of the geared disc 13, and the limiting discs 15 are slidably engaged within the grooves 7. When the geared disc 13 rotates, a new climbing tooth 14 on one side meshes with a new tooth hole 10, and the old climbing tooth 14 that was originally engaged in the tooth hole 10 rotates out, allowing the geared disc 13 to move vertically relative to the equidistant tooth hole plate 9.
[0031] Furthermore, the power assembly 4 includes a rotating shaft 16, a large gear 17, a small gear 18, and a servo motor 19. The rotating shaft 16 is housed within the structural housing 11, extending through the housing. Both ends of the rotating shaft 16 are coaxially connected to the geared disc 13. The servo motor 19 is fixedly installed within the structural housing 11. The output end of the servo motor 19 is coaxially connected to the small gear 18. One side of the small gear 18 meshes with the large gear 17, which is coaxially connected to the rotating shaft 16. The servo motor 19 provides power to drive the small gear 18 to rotate. The small gear 18, through the large gear 17, drives the rotating shaft 16 to rotate, thereby causing the geared disc 13 to rotate. By changing the rotation direction of the servo motor 19, the rotation direction of the geared disc 13 can be changed, thus enabling the device to rise or fall.
[0032] Furthermore, the spraying assembly 5 includes a material tank 20, a nozzle 21, and a liquid pump. The material tank 20 is mounted on the lifting platform 3, and the liquid pump is installed inside the material tank 20. The nozzle 21 is mounted above the material tank 20 and is sealed to the output end of the liquid pump. The liquid pump provides power to draw the spraying slurry, and the spraying material is sprayed out from the nozzle 21 under pressure. The nozzle 21 faces the exterior wall of the building. As the lifting platform 3 rises and falls, the nozzle 21 will rise or fall steadily and uniformly, spraying the insulation material evenly onto the exterior wall of the building.

[0047] Climbing tooth 14: The tooth-like structure on the geared disc 13 meshes tightly with the tooth holes 10 of the equidistant toothed plate 9. It is the key part for realizing the relative movement between the geared disc 13 and the equidistant toothed plate 9, thereby driving the movement of the lifting platform 3.
[0048] Limiting disc 15: Located on both sides of the geared disc 13, it is slidably engaged in the hoop groove 7 to prevent the geared disc 13 from loosening during rotation and to ensure the stability of the device structure.
[0049] Rotating shaft 16: It passes through the outer shell 11 and is coaxially connected to the geared disk 13 at both ends. It is used to transmit power and drive the geared disk 13 to perform circular motion.

[0051] Small gear 18: Coaxially connected to the output end of servo motor 19, meshing with large gear 17, transmitting the power of servo motor 19 to large gear 17, thereby driving rotating shaft 16 and geared disk 13 to rotate.
[0052] Servo motor 19: The core power output device of power component 4. After being powered on, it drives the pinion 18 to rotate. By controlling its forward and reverse rotation, the device can move up or down.
[0053] Material hopper 20: Installed on the lifting platform 3, it is used to store spray coating slurry. It is equipped with a liquid pump inside to provide material storage and transportation functions for spraying operations.
[0054] Nozzle 21: It is sealed to the output end of the liquid pump in the material tank 20, and sprays out the pressurized spray material evenly, which is directly applied to the exterior wall of the building to complete the spraying of the thermal insulation material.
[0055] Working Principle: In the power transmission stage, the power component 4 acts as the "heart" of the entire device, providing the power source for system operation. After the servo motor 19 is powered on, it converts electrical energy into mechanical energy, driving the small gear 18 at the output end to rotate. The small gear 18, through meshing transmission, drives the coaxially connected large gear 17 to rotate synchronously. Since the large gear 17 is coaxially fixed with the rotating shaft 16, the rotating shaft 16 immediately obtains torque, which in turn drives the geared disk 13 that runs through both ends of the structural shell 11 to perform circular motion. This transmission process uses gear sets to transmit power step by step, which not only ensures the stability of power transmission, but also amplifies the torque through the gear ratio of the large and small gears, providing strong power for the lifting and lowering of the device. The lifting and lowering control stage is the key to the vertical movement of the device. Two sets of hanging rails 1 are vertically installed on both sides of the building's exterior wall. The guide grooves 6 opened on their inner sides form a sliding engagement with the guide sliders 12 on the lifting component 2, providing precise guidance for the movement of the lifting platform 3 and preventing the device from deviating during the lifting and lowering process. The climbing teeth 14 on the geared disc 13 mesh tightly with the toothed holes 10 of the equidistant toothed plate 9, forming the vertical transmission mechanism of the device. When the geared disc 13 rotates under the drive of the power component 4, the climbing teeth 14 on one side disengage from the current toothed hole 10, while the new climbing teeth 14 on the other side mesh with the adjacent toothed hole 10. Through this alternating meshing, the vertical movement of the geared disc 13 relative to the equidistant toothed plate 9 is achieved. The sliding engagement structure between the limiting disc 15 and the clamping groove 7 plays an important role in this process. It tightly clamps the geared disc 13, restricting its radial displacement during rotation, effectively preventing structural instability caused by loose meshing, and ensuring a smooth and stable lifting process. By controlling the forward and reverse rotation of the servo motor 19, the rotation direction of the geared disc 13 can be flexibly adjusted, thereby realizing the upward or downward movement of the lifting platform 3. With this structural design, the device can achieve vertical lifting over ultra-long distances, meeting the construction needs of high-rise building exterior walls. In the spraying process, the spraying component 5 precisely sprays the insulation material onto the building's exterior wall surface. After the lifting platform 3 rises to the designated spraying height, the liquid pump in the material tank 20 starts, drawing the spraying slurry from the tank into the pipeline through a suction action, and then delivering it to the nozzle 21 under pressure. The nozzle 21 is aligned with the building's exterior wall, and as the lifting platform 3 rises and falls at a uniform speed, the spraying slurry is sprayed out from the nozzle 21 at a stable flow rate, forming a uniform and continuous insulation layer on the building's exterior wall surface. The stable output pressure of the liquid pump and the uniform movement of the lifting platform 3 work together to ensure that the insulation material is sprayed with consistent thickness and uniform coverage, effectively improving spraying quality and construction efficiency. Throughout the entire operation, the lifting component 2 and the spraying component 5 work in tandem. The lifting platform 3 remains stable during the rising and falling process, and the nozzle 21 always maintains a fixed distance and angle from the wall surface, avoiding spraying deviations caused by shaking, thus achieving efficient and precise spraying of the building's exterior wall insulation layer.
