Description

Technical Field

[0001] This utility model belongs to the field of construction technology of portal frame structure metal roofing engineering, and in particular relates to a transportation device for metal roofing panels of portal frame factory buildings. Background Technology

[0002] Portal frame structures, as a traditional structural system, are characterized by their light weight, high degree of industrialization, and With advantages such as short construction period and high overall economic benefits, metal roofs are widely used in industrial and civil buildings, including industrial, commercial, and cultural and entertainment public facilities. Their roof structures are also widely used in portal frame structures due to the unique advantages of metal roofs. Metal roofing materials mainly include aluminum alloys, copper, zinc alloys, and galvanized steel sheets. Because of their corrosion resistance, high strength, and light weight, to ensure the overall waterproofing effect of the metal roof, the surface metal roof panels generally use a 360-degree sliding support interlocking connection, while the upper roof panels should not be overlapped.

[0003] The metal roof panels are relatively long, generally the same length as the roof. Because of their thinness, they need to be stacked in multiple layers before being moved as a whole. During the movement, care must be taken to prevent bumps and deformation, which could lead to misalignment of the subsequent 360-degree interlocking connection and cause leaks. Therefore, the movement of the roof panels requires a large number of personnel and involves high-altitude operations, resulting in low overall movement efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a metal roofing panel transportation device for portal frame factory buildings. It features a portal frame roofing purlin as a sliding track, using multiple trolleys to increase the single-transport capacity of the roofing panels. Simultaneously, it reduces the risk of deformation and collisions during transportation. This solves the problem that metal roofing panels, which are generally the same length as the roof and thin, require multiple stacks before overall movement. During movement, care must be taken to prevent collisions and deformations that could lead to misalignment in the subsequent 360-degree interlocking connection, resulting in leaks.

[0019] Figure 1-4This invention illustrates a portal frame metal roofing panel transport device for a factory building, comprising multiple base supports 1, each welded from multiple square steel bars. Four track pulleys 2 are mounted below each base support 1. Each track pulley 2 is mounted on a vertical connecting member consisting of double roller sleeves and sleeve bearings. The vertical connecting member is made of bent steel plate. Adjustable slots 9 are provided at the four corners of the top of each base support 1. Two symmetrical screw rods 10 are welded to the top of each track pulley 2. The screw rods 10 pass through the adjustable slots 9 and are threaded with nuts 11. The track pulleys are moved by the coordinated use of the adjustable slots 9, screw rods 10, and nuts 11. Wheel 2 allows the two screw rods 10 to move within the adjustable groove 9, thus adjusting the distance between the two track pulleys 2 to suit the distance between two roof purlins 7 on a portal frame structure roof. Two symmetrical square vertical tubes 3 are welded to the rear of the top of the base bracket 1, and a horizontal handrail tube 4 is welded to the top between the two square vertical tubes 3. Multiple metal roof panels 5 are placed on the top of the multiple base brackets 1. Two symmetrical limiting lugs 6 are welded to the front of the top of the multiple base brackets 1. Multiple roof purlins 7 are located below the multiple base brackets 1. The track pulleys 2 at the bottom of the base bracket 1 are rotatably connected to the surface of the roof purlins 7, and the limiting lugs 6... A steel chain 8 is threaded through the chain, passing around multiple metal roof panels 5 and hooking onto square risers 3. Hook pins 12 are welded to opposite sides of each of the two square risers 3. A link on the steel chain 8 fits onto the surface of the hook pin 12. A limiting slot 13 is formed on the surface of the hook pin 12, and a limiting plate 14 is detachably inserted into the inner cavity of the limiting slot 13. The limiting plate 14 is adapted to the link of the steel chain 8. A frustum-shaped arc surface 15 is formed at the end of the hook pin 12 away from the square riser 3. Through the coordinated use of the limiting slot 13, the limiting plate 14, and the frustum-shaped arc surface 15, when the link on the steel chain 8 fits onto the surface of the hook pin 12, the frustum... The curved surface 15 can increase the smoothness of the chain link on the surface of the hook pin 12. After the limiting plate 14 is inserted into the limiting slot 13, it can limit the chain link and prevent the chain link from falling off the surface of the hook pin 12. A movable U-shaped connector 16 is installed on the surface of the horizontal handrail tube 4. A connecting rope 17 is installed on the U-shaped connector 16. The end of the connecting rope 17 away from the U-shaped connector 16 is installed with the limiting plate 14. Through the cooperation of the U-shaped connector 16 and the connecting rope 17, the limiting plate 14 can be installed on the surface of the horizontal handrail tube 4, ensuring that the limiting plate 14 will not be easily lost.

[0020] Working principle: When using this utility model, the trolley is placed on top of the roof purlin 7. The spacing of the track pulley 2 at the bottom of the base bracket 1 is adjusted according to the cooperation of the adjustable long groove 9, screw rod 10 and nut 11 to match the spacing of the two roof purlins 7. Since the metal roof panel 5 is thin and easily deformed, it generally needs to be stacked in multiple pieces. The metal roof panel 5 is placed on the top of the base bracket 1. Then, the steel chain 8 on the limiting lug 6 is pulled up and wrapped around the surface of the metal roof panel 5. Then, a link on the steel chain 8 is put on the surface of the hook pin 12. Then, the limiting insert 14 is picked up and inserted into the inner cavity of the limiting slot 13 to limit the link. The steel chain 8 limits the metal roof panel 5 and prevents the metal roof panel 5 from slipping off the top of the base bracket 1. Then, the multi-person universal horizontal handrail tube 4 pushes multiple trolleys together, thereby speeding up the overall construction speed.

[0021] In summary, this portal frame metal roofing panel transport device uses the portal frame roof purlins 7 as sliding tracks and trolleys to increase the single-transport capacity of metal roofing panels 5. Steel chains 8 limit the movement of multiple metal roofing panels 5, ensuring stability during transport. Multiple trolleys simultaneously increase the supporting area under the metal roofing panels 5, improving overall stability and balance, and preventing deformation from impacts. This achieves the goal of increasing the single-transport capacity of roofing panels while reducing the risk of deformation and impacts during transport. It also solves the problem of leaks caused by improper 360-degree interlocking connections due to the long length of the metal roofing panels (generally the same as the roof length) and their thinness, which necessitate multi-layer stacking before overall movement. The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
