Description

Technical Field

[0001] This invention relates to the field of component conveying technology, specifically to a high-altitude horizontal transport device for ultra-long, lightweight components. Background Technology

[0002] Color steel sheet is made on a continuous mill using cold-rolled strip steel or galvanized strip steel (electroplated and hot-dip galvanized) as the substrate. After surface pretreatment (degreasing and chemical treatment), one or more layers of liquid coating are applied by roller coating, followed by baking and cooling. The resulting sheet can be used as roofing material for building houses.

[0003] During the construction of the factory building, it is necessary to build the roof. However, the roof panels are long and difficult to connect in sections. After the roof panels are delivered to the roof, they need to be manually moved and positioned. Because the roof panels are too long, multiple people need to move them at high altitudes to align them with the required positions. The manual handling of roof panels is dangerous, difficult, and also affects the efficiency of the roof panel delivery.

[0004] To address this, we propose a high-altitude horizontal transport device for ultra-long, lightweight components. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1.

The downward movement of the connecting rod will push the moving plate downward. The downward movement of the moving plate will drive the second friction pad downward and stretch the spring. Further, the roof panel is placed on the upper side of the second friction pad. The pressing on the rotating ring is then removed. Under the action of the spring, the fixed plate and the moving plate clamp and fix the roof panel through the first friction pad and the second friction pad.

[0022] 3. In this invention, by inserting the wire rope in the winch into the opening on the lifting block, the winch further pulls the lifting block upward. During the process of the winch pulling the lifting block upward through the wire rope, the wire rope will pull the limiting ring to move upward along the inside of the lifting block.

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] This invention provides a high-altitude horizontal transport device for ultra-long, lightweight components. It is adaptable to roof panels of different sizes, facilitating the fixing and transport of roof panels of varying dimensions, and offering convenient transport capabilities for roof panels. Please refer to [link / reference]. Figure 1-5 The system includes roof purlins arranged at intervals, and also includes C-shaped steel rails 3 and a first threaded sleeve 20 and a second threaded sleeve 22 fixedly connected to each other. The C-shaped steel rails 3 are installed on one outer surface of the roof purlins 1. Both the roof purlins 1 and the C-shaped steel rails 3 are horizontal. The first threaded sleeve 20 is internally threaded with a first threaded rod 19, and the second threaded sleeve 22 is internally threaded with a second threaded rod 21. Both the first threaded sleeve 20 and the second threaded sleeve 22 are horizontal. A connecting block 18 is fixed to the ends of the first threaded rod 19 and the second threaded rod 21 that are far apart from each other. A fixing plate 12 is provided on the lower side of the connecting block 18, and a moving plate 15 is provided on the lower side of the fixing plate 12. A connecting plate is fixed to the lower surface of the connecting block 18. The lower end of rod 17 passes through fixed plate 12 and is fixedly connected to movable plate 15. Each end of fixed plate 12 is equipped with a pulley group that matches C-shaped steel rail 3. By rotating the first threaded sleeve 20 and the second threaded sleeve 22, the first threaded rod 19 and the second threaded rod 21 move along the first threaded sleeve 20 and the second threaded sleeve 22 respectively, which can adjust the distance between connecting blocks 18. By adjusting the distance between connecting blocks 18, the distance between fixed plates 12 and the distance between movable plates 15 can be adjusted, which can adapt to roof panels of different sizes, making it easier to fix and transport roof panels of different sizes, thus making the device more adaptable in use.

[0032] The pulley block includes a first limiting box 8, which is located on the upper side of the corresponding C-shaped rail 3. The lower surface of the first limiting box 8 is in contact with the upper surface of the corresponding C-shaped rail 3. The upper part of the first limiting box 8 near the fixing plate 12 is fixedly connected to the fixing plate 12. A first limiting plate 10 is fixed to the lower part of the first limiting box 8 near the fixing plate 12. A first limiting wheel 6 is rotatably mounted on the middle of the upper end of the first limiting plate 10 near the first limiting box 8. The first limiting wheel 6 is located on the upper side of the C-shaped rail 3 and is connected to the upper surface of the C-shaped rail 3. The upper surfaces are in contact with each other. At both ends of the bottom of the first limiting plate 10 near the first limiting box 8, a first rotating wheel 4 that matches the inner side of the C-shaped steel rail 3 is rotatably installed. The first limiting plate 10 can assemble and limit the first limiting wheel 6 and the first rotating wheel 4. A second limiting box 9 is fixed on the side of the fixing plate 12 away from the first limiting box 8. The upper part of the second limiting box 9 near the fixing plate 12 is fixedly connected to the fixing plate 12. A second limiting plate 11 is fixed on the lower part of the second limiting box 9 away from the fixing plate 12.

[0033] A second limiting wheel 7 is rotatably mounted on the upper middle part of the second limiting plate 11 near the second limiting box 9. The second limiting wheel 7 is located on the upper side of the C-shaped steel rail 3 and is in contact with the upper surface of the C-shaped steel rail 3. At both ends of the bottom of the second limiting plate 11 near the second limiting box 9, a second rotating wheel 5 matching the inner side of the C-shaped steel rail 3 is rotatably mounted. A retaining groove 2 is provided on the upper part of the roof purlin body 1 on the side away from the C-shaped steel rail 3. The second limiting plate 11 can assemble and limit the second limiting wheel 7 and the second rotating wheel 5. The retaining groove 2 facilitates the assembly between the roof purlin body 1 and the C-shaped steel rail 3. A first friction plate is fixed on the lower surface of the fixing plate 12. The first friction pad 13 is connected to the connecting rod 17, which passes through the first friction pad 13. The upper surface of the moving plate 15 is fixed with the second friction pad 14. The lower end of the connecting rod 17 passes through the second friction pad 14. The lower surface of the first friction pad 13 and the upper surface of the second friction pad 14 are located outside the connecting rod 17 and are fixed with springs 16. The first limiting wheel 6, the second limiting wheel 7, the first limiting box 8 and the second limiting box 9 limit the corresponding ends of the device, so that the device can stably transport the roof panel. After the roof panel is transported to the required position, the rotating ring 31 is pressed to release the limitation on the roof panel, so that the workers can remove the roof panel and assemble it.

[0034] A rotating ring 31 is fixed to the outer annular surfaces of the first threaded sleeve 20 and the second threaded sleeve 22 at their closest points. The rotating ring 31 allows the first threaded sleeve 20 and the second threaded sleeve 22 to rotate easily. Limiting grooves 23 are formed on the outer annular surfaces of the middle of both the first threaded sleeve 20 and the second threaded sleeve 22. First limiting blocks 27 are fitted onto the limiting grooves 23, allowing the first threaded sleeve 20 and the second threaded sleeve 22 to rotate stably. A lifting block 24 is fixed to the upper surface of the first limiting block 27. The middle of the lifting block 24 and the middle of one side are open. A limiting ring 25 is slidably installed in the middle of the lifting block 24. The limiting ring 25 has a matching opening corresponding to the opening on one side of the lifting block 24. The lower surface of the first limiting block 27... A fixing block 26 is fixed together, and a horizontal sliding groove 29 is opened in the fixing block 26. The two ends of the sliding groove 29 are provided with matching second limiting blocks 28. The ends of the second limiting blocks 28 that are far apart are fixed with horizontal sliding rods 30. The sliding rods 30 pass through the fixing block 26 and are fixedly connected to the connecting blocks 18 at the corresponding ends. By inserting the wire rope in the winch into the opening on the lifting block 24, the lifting block 24 is further pulled upward by the winch. During the process of the winch pulling the lifting block 24 upward by the wire rope, the wire rope will pull the limiting ring 25 to move upward along the lifting block 24. The limiting ring 25 will close the opening on the lifting block 24, so that the winch can stably pull the lifting block 24 upward by the wire rope.

[0035] The working principle of this invention is as follows: During use, the rotating ring 31 rotates, which in turn drives the first threaded sleeve 20 and the second threaded sleeve 22 to rotate. During this rotation, the first threaded sleeve 20 and the second threaded sleeve 22 rotate along the first limiting block 27 via the limiting groove 23, ensuring stable operation of the first threaded sleeve 20 and the second threaded sleeve 22. This allows the first threaded rod 19 and the second threaded rod 21 to move along the first threaded sleeve 20 and the second threaded sleeve 22 respectively, adjusting the spacing between the connecting blocks 18. By adjusting the spacing between the connecting blocks 18, the spacing between the fixing plates 12 and the moving plates 15 can be adjusted, accommodating roof panels of different sizes. This facilitates the fixing and transport of roof panels of different sizes, making the device adaptable to various applications. With a wider range, during the adjustment of this device, the slide bar 30 drives the second limiting block 28 to move along the slide groove 29 on the fixed block 26, so that the device can be adjusted stably. After the device is adjusted, the rotating ring 31 is pressed down further. During the pressing of the rotating ring 31, the rotating ring 31 drives the first threaded rod 19 and the second threaded rod 21 to move downward through the first threaded sleeve 20 and the second threaded sleeve 22. During the downward movement of the first threaded rod 19 and the second threaded rod 21, the connecting rod 17 will move downward along the fixed plate 12 through the connecting block 18 fixed at the end. During the downward movement of the connecting rod 17, the moving plate 15 will be pushed downward. During the downward movement of the moving plate 15, the second friction pad 14 will be moved downward and the spring 16 will be stretched, so that the roof panel is placed on the upper side of the second friction pad 14.

[0036] After placing the roof panel on the upper side of the second friction pad 14, the pressing of the rotating ring 31 is released. Under the action of the spring 16, the moving plate 15 and the second friction pad 14 move upward. During the upward movement of the moving plate 15, the fixed plate 12 and the moving plate 15 clamp and fix the roof panel through the first friction pad 13 and the second friction pad 14, so that the first friction pad 13 and the second friction pad 14 can limit the position of the roof panel. In use, the roof purlin body 1 is installed at intervals on the top of the house. The winch is installed at the end where the roof panel needs to be lifted. The wire rope in the winch is inserted into the opening on the lifting block 24. The lifting block 24 is pulled upward by the winch. During the upward pulling of the lifting block 24 by the winch through the wire rope, the wire rope will pull the limiting ring 25 to move upward along the inside of the lifting block 24. The limiting ring 25 will limit the position of the lifting block. The opening on 24 is closed, allowing the winch to stably pull the lifting block 24 upward via the wire rope. This causes the first rotating wheel 4 and the second rotating wheel 5 to be inserted into the inner side of the C-shaped steel rail 3 on the roof purlin body 1 at both ends. As the first rotating wheel 4 and the second rotating wheel 5 move along the inner side of the corresponding C-shaped steel rail 3, the first limiting wheel 6 and the second limiting wheel 7 move along the upper side of the corresponding C-shaped steel rail 3. Under the action of the first limiting plate 10 and the second limiting plate 11, the first limiting wheel 6, the second limiting wheel 7, the first limiting box 8, and the second limiting box 9 limit the corresponding ends of the device during use. The device can be used stably during the conveying of the roof panel. After the roof panel is conveyed to the required position, the rotating ring 31 is pressed to release the limitation on the roof panel, so that the workers can remove the roof panel and assemble it.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

3. The method of using the high-altitude horizontal transport device for ultra-long lightweight components according to claim 2, characterized in that, The specific details are as follows: During use, the rotating ring rotates, which in turn drives the first and second threaded sleeves to rotate. As the first and second threaded sleeves rotate, they rotate along the first limiting block via the limiting groove, ensuring stable operation. This allows the first and second threaded rods to move along the first and second threaded sleeves respectively, adjusting the spacing between the connecting blocks. Adjusting the spacing between the connecting blocks allows for adjustment of the spacing between the fixed plates and the moving plates, accommodating roof panels of different sizes and facilitating the fixing and transport of roof panels of varying dimensions. During the adjustment of the device, the slide bar drives the second limiting block to move along the slide groove on the fixed block, so that the device can be adjusted stably. After the device is adjusted, the rotating ring is pressed down further. During the pressing of the rotating ring, the rotating ring drives the first threaded rod and the second threaded rod to move downward through the first threaded sleeve and the second threaded sleeve. During the downward movement of the first threaded rod and the second threaded rod, the connecting rod will move downward along the fixed plate through the connecting block fixed at the end. During the downward movement of the connecting rod, the moving plate will be pushed downward. During the downward movement of the moving plate, the second friction pad will be moved downward and the spring will be stretched, so that the roof panel is placed on the upper side of the second friction pad. After placing the roof panel on top of the second friction pad, release the pressure on the rotating ring. Under the action of the spring, the moving plate and the second friction pad move upward. During the upward movement of the moving plate, the fixed plate and the moving plate clamp and fix the roof panel through the first friction pad and the second friction pad, so that the first friction pad and the second friction pad can limit the position of the roof panel. In use, the main body of the roof purlins is installed at intervals on the top of the building. The winch is installed at the end where the roof panel needs to be lifted. The wire rope in the winch is then inserted into the opening on the lifting block. The lifting block is then pulled upward by the winch. During the upward pulling of the lifting block by the winch through the wire rope, the wire rope will pull the limiting ring. As the device moves upward along the inside of the lifting block, the limiting ring closes the opening on the lifting block, allowing the winch to stably pull the lifting block upward via the wire rope. This causes the first and second rotating wheels to be inserted into the inner sides of the C-shaped steel rails on the roof purlins at both ends. As the first and second rotating wheels move along the inner sides of their respective C-shaped steel rails, the first and second limiting wheels move along the upper sides of their respective C-shaped steel rails. Under the action of the first and second limiting plates, the first and second limiting wheels, as well as the first and second limiting boxes, limit the corresponding ends of the device during use. After the roof panel is transported to the required position, the rotating ring is pressed to release the limitation on the roof panel.
