Description

Technical Field

[0001] This invention relates to an aerial transport device, and more specifically, to an aerial rapid horizontal transport device and method for roof panels of multi-span, large-span structures. Background Technology

[0002] In the field of building construction, the application of multi-span, large-span portal frame structure factory projects is becoming increasingly widespread. Such projects have large distances in both the length and width directions of the structure, making the high-altitude transportation of roof panels extremely difficult and the construction efficiency very low.

[0003] In existing technologies, there are two main methods for transporting roof panels during the construction of portal frame structures: First, using a crane to hoist the profiled metal sheets onto the roof, followed by manual lifting for horizontal transport. This method is only suitable for short-distance transport of profiled metal sheets. For long-distance transport, a large number of construction workers are required, resulting in extremely low construction efficiency. Furthermore, the large number of people walking at heights and their frequent movement pose serious safety hazards such as falls from heights. Second, when the surrounding area is spacious, a high-altitude roofing sheet press is used to transport the roof panels directly to the vicinity of the roof. This method is only suitable for single-span structures with ample space for transporting profiled metal sheets. However, the surrounding space for multi-span, large-span portal frame structure factory projects is mostly only the width of a road, making it impossible to use a high-altitude roofing sheet press for construction due to space constraints.

[0004] It is known that the existing methods of high-altitude transportation of roof panels cannot meet the construction needs of roof panels for multi-span, large-span structures, resulting in problems such as low transportation efficiency, significant safety hazards, and poor site adaptability.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner to facilitate understanding.

[0023] The technical solution of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Figures 1 to 11 The schematic structures of the multi-span large-span roof panel transportation device according to embodiments of the present invention are shown from different angles and at different transportation stages.

[0025] like Figures 1 to 11 As shown, the multi-span, large-span roof panel transport device 100 provided by this invention includes a main structure 2, a rolling assembly 1 disposed below the main structure 2, and a sliding hoisting assembly 3 disposed on the main structure 2. The main structure 2 further includes a frame base 21 for placing the panels to be transported (hereinafter referred to as panels), a support frame 22 disposed above the frame base 21, and an adjusting beam 23 disposed on the support frame 22. The rolling assembly 1 is disposed below the frame base 21 and is used to drive the entire main structure 2 to roll. The sliding hoisting assembly 3 is limited to movement on the adjusting beam 23 and is used to hoist the panels to be transported from the frame base 21 to a preset position on the roof purlins 4, thereby achieving both coarse and fine adjustment of the position of the panels to be transported. That is, the main structure 2 can drive the panels to be transported to move on the roof purlins 4 under the action of the rolling assembly 1, and then the sliding hoisting assembly 3 hoists the panels to be transported onto the roof purlins 4 where the panels are to be installed.

[0026] When the length of the panels to be transported is large, i.e. for multi-span large-span structural roof panels, multiple multi-span large-span structural roof panel transport devices can be set up for synchronous transport. The attached figure shows a specific example of using 3 sets of multi-span large-span structural roof panel transport devices to simultaneously transport large-span panels.

[0027] In a specific embodiment of the present invention, the rolling assembly 1 includes at least two rotating circular tubes; wherein, the rotating circular tubes further include a hollow circular tube 13 and round steel 11 whose two ends are limited inside the hollow circular tube 13 by bearings 12. The hollow circular tube 13 can roll around the round steel 11 under the action of the bearings 12. During the assembly process, the two ends of the round steel 11 can be welded and fixed to the frame base 21 of the main structure 2, thereby driving the entire device to move in position through the rolling assembly 1.

[0028] In addition, the frame base 21 of the main structure 2 includes a first long rod and a second long rod arranged in parallel, and several transverse connecting rods 24 arranged between the first long rod and the second long rod to form a stable overall frame structure. Then, the support frame 22 is vertically arranged on the first long rod or the second long rod, and inclined reinforcing ribs are set between the support frame and the corresponding long rod to ensure the stability of the overall structural strength.

[0029] To facilitate the assembly of the sliding hoisting assembly 3, the aforementioned adjusting beam 23 can be made of H-beams. The sliding hoisting assembly 3 includes symmetrically positioned rollers 32 within the steel grooves of the H-beams, a wrapping steel plate 31 that wraps around the limiting rollers 32, and lifting lugs 33 located below the wrapping steel plate 31. The attached figure shows an example with two rollers on each side of the H-beams. The four rollers are limited within the H-beams by the wrapping steel plate 31, forming a miniature hoist trolley function.

[0030] The aforementioned rolling assembly 1, main structure 2, and sliding hoisting assembly 3 can all be welded and fabricated using materials readily available on-site. Specific dimensions can be set and adjusted according to construction requirements. The overall device has low cost, is easy to assemble, and highly flexible. Furthermore, placing the support frame on any of the long poles prevents it from obstructing the frame base 21, facilitating the hoisting of the sheet metal 9. The adjusting beam 23 is positioned in the same direction as the rolling assembly, and its length is greater than the width of the frame base 21, thus enabling the sheet metal 9 on the frame base 21 to be transported to the designated position on the roof purlin 4, achieving automated unloading.

[0031] To ensure the stability of the device's movement trajectory on the roof purlins 4, corresponding connecting plates 26 can be installed below the frame base 21, and limiting baffles 25 can be installed below the connecting plates 26. The two ends of the round steel 11 are welded and fixed between the corresponding connecting plates 26, and the position of the limiting baffles 25 is adapted to the spacing of the roof purlins 4 to limit the movement of the frame base 21. That is, the movement of the frame base 21 is limited by the cooperation of the limiting baffles and the purlins, preventing the position from shifting during the movement.

[0032] Furthermore, multiple fixing plates are provided on both sides of the frame base 21, and fixing holes are provided on each fixing plate. After the multi-span large-span structure roof panel transport device is moved to the roof purlin 4 by hoisting 6, the device and the roof purlin 4 can be temporarily tied and fixed 5. The temporary binding effect can be achieved by using straps and fixing plates. That is, the frame base 21 can be temporarily tied and fixed to the roof purlin 4 by passing straps or ropes through the fixing holes.

[0033] In another specific embodiment of the present invention, the multi-span large-span structure roof panel transportation device further includes a bracket 7; wherein, the structure of the bracket 7 is similar to that of the frame base 21, and it can be limited on the frame base 21, including multiple support rods 71. The panels to be transported are hoisted onto the multiple brackets 7 by the hoisting spreader 8. The bracket 7 can avoid the deformation of the panels that are easily caused by the direct hoisting of the panels. After the panels 9 are supported by the bracket 7, the hoisting operation of the panels 9 can be realized by the hoisting bracket 7, which can simplify the transportation process and improve transportation efficiency while ensuring the integrity of the panels 9. The bracket 7 can be fixed to the frame base 21 by binding with straps or the like, or a corresponding limiting structure can be set on the frame base 21 and the bracket 7. The two can be matched and limited by the limiting structure. For example, a positioning groove / positioning post can be set on the frame base 21, and a corresponding positioning post / positioning groove can be set on the bottom of the bracket 7. After the bracket 7 is placed on the frame base 21, the two can be temporarily limited by the positioning groove and positioning post, which facilitates the hoisting operation of the bracket 7 and the plate to be transported on it.

[0034] After the panels are transported to the preset position by the rolling component 1, the panels 9 (including the brackets 7 supporting the panels) are further hoisted to the designated position of the roof purlins 4 by the sliding hoisting component 3 of the multi-span large-span structure roof panel transport device. After the brackets 7 and the panels to be transported are hoisted to the roof purlins 4 as a whole, the brackets 7 and the roof purlins 4 can be temporarily tied and fixed in time. During the construction process, the workers can take the panels 9 off the brackets 7. After all the panels 9 have been used, the limit between the brackets 7 and the roof purlins 4 can be released, and then the brackets 7 can be hoisted away for the next cycle of use.

[0035] In a specific example of the present invention, the rolling assembly includes two rotating round tubes, each comprising two round steel bars with a diameter of 80 mm and a length of 3330 mm, two round tubes with a specification of 152x6 and a length of 2930 mm, and four sets of bearings with an outer diameter of 140 mm and an inner diameter of 80 mm. The above materials are used to assemble the two rotating round tubes. The main structure is made of long rods, support frames, and adjusting beams of hot-rolled H-beams of HW100x100x6x8, transverse connecting rods made of C8 channel steel, and welded with 10 mm steel plates. A limiting baffle is welded below the H-beams welded to the rotating round tubes to prevent the entire device from moving out of the guide position. The device has a simple structure and low manufacturing cost. The size and materials can be adjusted on-site according to the spacing of the roof purlins and construction requirements.

[0036] It is understood that the multi-span large-span structure roof panel transportation device provided by the present invention can transport multiple panels at a time and can unload itself. It can not only effectively reduce the number of personnel transporting high-altitude panels, but also improve the transportation efficiency over long distances (greater than 20m), adapt to construction scenarios with narrow sites, and avoid dependence on large equipment.

[0037] Corresponding to the above-mentioned multi-span large-span structure roof panel transportation device, the present invention also provides a multi-span large-span structure roof panel transportation method, which utilizes the above-mentioned multi-span large-span structure roof panel transportation device to transport the panels to be transported.

[0038] Specifically, Figure 13 A schematic flow diagram of a method for transporting roof panels of a multi-span, large-span structure according to an embodiment of the present invention is shown. Figure 13 As shown, the method for transporting roof panels of multi-span, large-span structures according to an embodiment of the present invention includes at least the following steps: S100: The rolling components are welded and fixed to the bottom of the main structure, and the sliding hoisting components are assembled on the adjusting beam of the main structure to form a multi-span, large-span structure roof panel transportation device. S200: Hoist at least two multi-span large-span structure roof panel transport devices onto the roof purlins to be constructed, and temporarily bind and limit them; S300: The bracket is pre-hoisted onto the frame base of the main structure and secured, and the plates to be transported are hoisted onto the bracket; S400: Release the binding between the multi-span large-span structure roof panel transport device and the roof purlins, and push the multi-span large-span structure roof panel transport device to the designated position and re-bind and limit it; S500: The bracket and the material to be transported on the bracket are hoisted onto the roof purlin using a sliding hoisting assembly, and the bracket is then bound and limited to the roof purlin. S600: Release the binding between the multi-span large-span structure roof panel transport device and the roof purlins, and move the multi-span large-span structure roof panel transport device to the initial position to cycle through the hoisting operation of the panels to be transported.

[0039] Specifically, firstly, the frame base, support frame, and adjusting beam of the main structure are processed according to the size requirements. The support frame is then vertically welded to the designated position on the frame base, and the adjusting beam is welded to the top of the support frame to complete the assembly of the main structure. Then, the assembled rolling components are welded and fixed to the bottom of the main structure, and the sliding hoisting components are assembled on the adjusting beam of the main structure. Anti-detachment buckles are installed to ensure that the sliding hoisting components can move smoothly along the adjusting beam without the risk of overturning or detachment, thus forming a multi-span large-span structure roof panel transportation device. Then, the assembled device is subjected to overall testing, including the weld quality of each welded part, the rotation performance of the rolling components, the movement performance of the sliding hoisting components, and the fixing reliability of the limiting and fixing components, such as connecting plates and limiting baffles. Only after passing the test can it be put into use.

[0040] Then, a truck crane is used to lift at least two qualified multi-span large-span structure roof panel transport devices onto the roof purlins to be constructed. Depending on the length of the roof panel, multiple sets of devices can be assembled, usually 2-4 sets. The specifications and dimensions of the multiple sets of devices are consistent to ensure the synchronicity of subsequent coordinated transportation. Then, push the device along the roof purlin to the initial feeding point, pass the cable ties and other fasteners through the fixing holes of the fixing plate and lock them around the roof purlin to complete the temporary binding and limiting of the device and the roof purlin. After fixing, check the stability of the device. Only after there is no shaking or deviation can subsequent operations be carried out. Then, the bracket is lifted onto the frame base of the main structure by a truck crane. The position of the bracket is adjusted so that it is stably placed in the center of the frame base. Nylon straps are used to tie and fix the bracket to the frame base, ensuring that the straps are tightened evenly and without loosening. Next, the panels to be transported are hoisted onto the brackets using a truck crane. The position of the panels is adjusted according to the size of the roof panels to ensure that the center of gravity of the panels coincides with the center of gravity of the brackets, thus avoiding uneven loading. After placement, the panels are secured to the brackets with anti-slip straps to prevent the panels from sliding or deforming during transportation.

[0041] Afterwards, three groups of roof workers released the fasteners between the device and the roof purlins, and slowly pushed the device along the roof purlins to the construction point. During the pushing process, it was ensured that multiple devices moved synchronously to avoid bending or deformation of the panels due to inconsistent speeds. Once the device is moved to the designated construction point on the roof, immediately re-bind and limit the device to the roof purlins. After fixing, check the position and stability of the device to ensure the safety of the hoisting operation.

[0042] Workers push the sliding hoisting assembly to move laterally along the adjusting beam, precisely moving the bracket and panels above the construction point of the roof purlin. The position is adjusted to align the panels with the installation line of the purlin, achieving precise alignment. The bracket and roof purlin are temporarily tied and fixed with straps to prevent the roof panels from sliding during installation. Disconnect the sliding hoisting assembly from the bracket to complete the transportation and hoisting of a single batch of roof panels. Then, the transportation and hoisting of the next batch of roof panels can be repeated until the transportation of roof panels in the construction area is completed.

[0043] As can be seen, the multi-span large-span roof panel transportation device and method provided by the present invention can significantly improve construction efficiency, reduce personnel input and safety hazards, and enhance the safety of high-altitude operations. In addition, multi-span large-span roof panel transportation devices of different specifications can be customized and adapted according to the spacing of roof purlins and the size of the panels. At the same time, it can be operated directly on the already constructed roof purlins without the need for additional operating platforms, making it highly adaptable to different sites. The assembly, fixing, moving, and hoisting of the device are all simple and convenient, requiring no professional technicians. Ordinary construction workers can operate it after simple training. Furthermore, the construction method adopts standardized steps, and the synchronization of multiple devices working together is easy to control, which can realize the standardization and mechanization of roof panel transportation construction and improve the overall construction management level.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
