Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic transportation equipment, and in particular to a rooftop photovoltaic component transportation device. Background Art

[0002] With the gradual development of the photovoltaic industry, the demand for the installation of prefabricated sunrooms has also gradually increased. When industrial and commercial power stations are put into construction, after the brackets, materials, photovoltaic panels and other photovoltaic components are hoisted to the color steel tile roof, if they are transported and installed manually on the roof, there are problems such as high construction intensity, low construction efficiency, and easy damage to the roof paint due to manual transportation. At the same time, there is also the problem of hidden cracks during transportation due to the large area of ​​photovoltaic panels. As a result, some transportation devices have appeared on the market, which can use transportation carts to transport photovoltaic components on the roof or on the photovoltaic brackets laid on the roof.

[0003] However, the height of the transport carts on the existing market is usually low, which makes it inconvenient to use when manually pushing the transport cart. At the same time, the transport devices on the existing market usually use cams to slide with concave guide rails, which are prone to problems such as difficulty in cleaning the concave guide rails and the presence of foreign matter in the concave guide rails, which leads to poor structural stability and low transportation efficiency of the transport devices. In addition, the transport devices on the existing market can usually only be used in the form of photovoltaic brackets built on the roof as guide rails, and have low versatility. Different transport devices need to be used for transportation during the construction of the entire roof photovoltaic module, which leads to high costs and low construction efficiency.

[0056] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0057] In order to solve at least one of the above technical problems, the present invention provides a rooftop photovoltaic module transportation device, which is used in the transportation process of photovoltaic modules on the roof. Figures 1 to 22 The transport device 10 of the present invention will now be described.

[0058] In some embodiments, Figures 1 to 16 As shown, the transport device 10 of the present invention can be directly used in the process of transporting the components to be assembled on the roof 20, so as to transport the photovoltaic components such as photovoltaic brackets, photovoltaic panels, materials, etc. hoisted to the roof 20 to the designated installation location for construction. Figure 1 As shown, the transport device 10 of the present invention may include a platform assembly 200 and a propulsion assembly 300 .

[0059] like Figures 1 to 4 As shown, the top of the platform assembly 200 is used to carry the components to be assembled, and the bottom of the platform assembly 200 is slidably guided with the guide rail 110. It should be noted that the components to be assembled can be photovoltaic components, which include photovoltaic brackets, photovoltaic panels, materials, etc. In addition, as Figure 3 and Figure 4 As shown, the propulsion assembly 300 is arranged on the platform assembly 200 and has a handrail beam 330, and the handrail beam 330 is used to drive the platform assembly 200 to move along the guide rail 110 under the action of an external force. In other words, the transport device 10 of the present invention includes a transport vehicle constructed by the platform assembly 200 and the propulsion assembly 300, and the transport vehicle is provided with a handrail beam 330 that can be used for manual pushing.

[0060] The transport device 10 of the present invention, by setting up a platform component 200, and making the top of the platform component 200 be used to carry the parts to be assembled, and the bottom thereof cooperates with the external guide rail 110 for sliding guidance, thereby carrying and driving the parts to be assembled to slide along the guide rail 110, solving the problem of manual handling required after the photovoltaic components such as photovoltaic panels, brackets and materials are hoisted, reducing the construction handling intensity and improving the construction efficiency.

[0061] In addition, the present invention increases the overall height of the transportation device 10 by disposing a propulsion assembly 300 with a handrail beam 330 on the platform assembly 200, which facilitates manual pushing of the handrail beam 330 to drive the platform assembly 200 to move along the guide rail 110, thereby improving the convenience of moving the platform assembly 200 along the guide rail 110, avoiding the problem of inconvenience in pushing due to the low height of the transportation device 10, thereby improving the user experience, and further improving the construction efficiency while ensuring the transportation efficiency of the transportation device 10.

[0062] In some embodiments, Figures 1 to 4 As shown, the transport device 10 of the present invention may also include a guide rail assembly 100. Specifically, the guide rail assembly 100 is arranged on the roofing material 22 of the roof 20, and has a plurality of parallel guide rails 110 and a plurality of mounting structures 120. Each guide rail 110 is detachably connected to the roof 20 through a plurality of mounting structures 120. It should be noted that the roofing material 22 of the roof 20 may use colored steel tiles. In addition, the roof 20 may be centered on the ridge line 21 in the middle, presenting a shape that is high in the middle and low at both ends. Accordingly, a plurality of parallel guide rails 110 may be arranged on the roofing material 22 of the roof 20 in an interval arrangement along the longitudinal direction of the roof 20, and may be arranged parallel to the ridge line 21.

[0063] Thus, the transport device 10 of the present invention realizes the transportation of roof photovoltaic panels, photovoltaic brackets and materials by laying the guide rails 110 on the roof 20 and using a transport vehicle that cooperates with the guide rails 110. During the construction process, the walkway board of the roof 20 can be installed on one side of the factory building first, and the guide rails 110 can be laid separately along the roof 20. The photovoltaic brackets and materials hoisted to the roof 20 are transported to the designated installation location by using a pulley vehicle, and the construction of the photovoltaic brackets is carried out to quickly complete the distribution and installation of the photovoltaic brackets, thereby improving the overall construction efficiency.

[0064] The transport device 10 of the present invention arranges a plurality of parallel guide rails 110 on the roofing material 22 of the roof 20, and makes each guide rail 110 detachably connected to the roof 20 through the mounting structure 120. In this way, when no photovoltaic bracket is erected on the roof 20, the transport device 10 can be used to transport the photovoltaic components on the roof 20. This makes the transport device 10 applicable to the erection process of the photovoltaic bracket, thereby improving the versatility of the transport device 10.

[0065] In some embodiments, Figures 1 to 4As shown, the platform assembly 200 in the transport device 10 of the present invention may include a plurality of pulley assemblies 210, a plurality of platform beams 220, and a plurality of platform longitudinal beams 230. Specifically, each of the plurality of platform beams 220 is arranged parallel to the guide rail 110. The plurality of pulley assemblies 210 are arranged at the bottom of the platform beams 220, and the bottom of each platform beam 220 is detachably connected to a plurality of spaced pulley assemblies 210. Each of the plurality of platform longitudinal beams 230 is arranged perpendicular to the platform beams 220 and is detachably connected to the plurality of platform beams 220, respectively, for carrying the components to be assembled.

[0066] Specifically, the plurality of platform cross beams 220 and the plurality of platform longitudinal beams 230 can be detachably connected using fasteners 260. Figure 5 As shown, the fastener 260 may be a bolt assembly, and the bolt assembly may include a plastic wing nut and a screw. Thus, the transport device 10 of the present invention uses a plurality of platform beams 220 and a plurality of platform longitudinal beams 230 to build a basic frame of the platform assembly 200, and uses a plurality of pulley assemblies 210 disposed at the bottom of the platform beams 220 to achieve the guiding cooperation between the platform assembly 200 and the guide rail 110.

[0067] Thus, the platform assembly 200 of the transport device 10 of the present invention can be constructed by a plurality of platform cross beams 220, a plurality of platform longitudinal beams 230 and a plurality of pulley assemblies 210, which simplifies the structure of the platform assembly 200, thereby reducing the production cost of the transport device 10. At the same time, the plurality of platform cross beams 220, the plurality of platform longitudinal beams 230 and the plurality of pulley assemblies 210 are all installed in a detachable connection manner, which improves the assembly convenience of the platform assembly 200, thereby reducing the production cost of the transport device 10. In addition, the lengths of the platform cross beams 220 and the platform longitudinal beams 230 can be adjusted according to the size parameters of the guide rail assembly 100, realizing the convenient adjustment of the overall shape and area of ​​the platform assembly 200 and the position of the pulley assembly 210, thereby further improving the versatility of the transport device 10.

[0068] In some optional embodiments, such as Figures 1 to 4 As shown, the transport device 10 of the present invention can be provided with two parallel guide rails 110, two parallel platform beams 220 and a plurality of platform longitudinal beams 230 to form a platform assembly 200, and the distance between the two platform beams 220 is equal to the distance between the two guide rails 110, so that the two platform beams 220 correspond to the two guide rails 110 one by one, and the plurality of pulley assemblies 210 at the bottom of each platform beam 220 are provided corresponding to one guide rail 110. Thus, the structure of the transport device 10 of the present invention is further simplified, thereby further reducing the production cost.

[0069] In other optional embodiments, the transport device 10 of the present invention may also be provided with more than three parallel guide rails 110, and more than three parallel platform beams 220 and a plurality of platform longitudinal beams 230 are provided to form a platform assembly 200, and the plurality of platform beams 220 correspond one to one with the plurality of guide rails 110, and the plurality of pulley assemblies 210 at the bottom of each platform beam 220 are provided corresponding to a guide rail 110. Thus, the longitudinal dimension of the transport device 10 of the present invention can be freely adjusted according to the use requirements, so as to facilitate the transportation of large photovoltaic modules, thereby further ensuring the transportation efficiency.

[0070] In some embodiments, Figure 5 As shown, the pulley assembly 210 in the transport device 10 of the present invention may include a concave pulley 213. Accordingly, the guide rail 110 in the transport device 10 of the present invention may be a convex rail. Specifically, the axial direction of the concave pulley 213 is perpendicular to the guide rail 110, and the axial dimension of the concave pulley 213 is greater than the width of the guide rail 110, so that the concave pulley 213 is slidably connected to the guide rail 110 in a manner that the middle concave surface 2131 contacts the upper surface 111 of the guide rail 110. As a result, the pulley assembly 210 in the transport device 10 of the present invention can be stably mounted on the guide rail 110, improving the stability of the guide cooperation between the platform assembly 200 and the guide rail 110, thereby further ensuring the transport efficiency of the transport device 10.

[0071] In addition, the pulley assembly 210 in the transport device 10 of the present invention can also use a cam, and accordingly, the guide rail 110 can be set as a groove-type track. Specifically, the axial direction of the cam is set perpendicular to the guide rail 110, and the axial dimension of the cam is smaller than the width of the guide rail 110, so that the cam is slidably connected to the guide rail 110 in a manner of being embedded in the middle groove of the guide rail 110. Therefore, the pulley assembly 210 in the transport device 10 of the present invention can achieve the stability of the guide cooperation between the platform assembly 200 and the guide rail 110, thereby further ensuring the transportation efficiency of the transport device 10.

[0072] In some embodiments, Figure 5 As shown, the pulley assembly 210 in the transport device 10 of the present invention may further include a pulley mounting plate 214. The pulley mounting plate 214 is in a U-shape with an opening facing downward, and the middle portion thereof is used to accommodate the pulley. Specifically, a pulley through bolt 216 is provided in the middle portion of the pulley mounting plate 214 to mount the pulley, and the pulley through bolt 216 is provided to penetrate the pulley mounting plate 214 in the longitudinal direction. In addition, the top of the pulley mounting plate 214 is detachably connected to the platform cross beam 220 by means of a vertically arranged pulley mounting bolt 215.

[0073] In some optional embodiments, the guide rail 110 in the transport device 10 of the present invention may be a clamp 121 type guide rail 110 to achieve rapid laying of the guide rail 110. Figures 3 to 6 As shown, the mounting structure 120 may include a clamp 121. Specifically, the upper end of the clamp 121 is detachably connected to the guide rail 110, and the lower end of the clamp 121 is detachably connected to the corrugation 23 of the roofing material 22, so as to install the guide rail 110 on the roofing material 22. It should be noted that the roofing material 22 of the roof 20 may use a color steel tile, and the corrugation 23 of the roofing material 22 may be a color steel tile crest.

[0074] In a specific embodiment, the clamp 121 may have an L-shaped clamp body and a C-shaped clamp side body, the top arm of the clamp body is detachably connected to the guide rail 110 by a fastener 260, the side arm of the clamp body is detachably connected to the clamp side body by a fastener 260, and the side arm of the clamp body and the clamp side body are respectively clamped on both sides of the color steel tile crest in the transverse direction. In addition, the clamp 121 is selected to match the corresponding color steel tile model. In addition, if Figure 3 As shown, the heights of the plurality of color steel tile crests in the vertical direction are the same, and the upper surfaces 111 of the plurality of color steel tile crests are located in the same plane to stably support the guide rail 110 .

[0075] Therefore, the guide rail 110 in the transportation device 10 of the present invention is suitable for the corner color steel tile roof. During installation, the clamp 121 can be used to directly clamp it on the color steel tile crest of the roof 20, thereby realizing a convenient connection between the guide rail 110 and the roof 20 and improving construction efficiency.

[0076] In some other optional embodiments, the guide rail 110 in the transport device 10 of the present invention may also be a sleeper steel guide rail 110 to increase the support strength of the roof 20 on the guide rail 110. Figures 7 to 9 As shown, the mounting structure 120 may include a sleeper 122. Specifically, the sleeper 122 is disposed between the guide rail 110 and the roofing material 22, the upper side of the sleeper 122 is detachably connected to the guide rail 110, and the lower side of the sleeper 122 is detachably connected to the roof support 24 below the roofing material 22. It should be noted that the sleeper 122 may be a sleeper steel.

[0077] In a specific embodiment, Figure 7 and Figure 8 As shown, the guide rail assembly 100 in the transport device 10 of the present invention includes a plurality of parallel sleepers 122, and the plurality of sleepers 122 are arranged on the roofing material 22 at intervals along the transverse direction of the roof 20. Specifically, the extension direction of each sleeper 122 is parallel to the extension direction of the corrugations 23 of the roofing material 22, and each sleeper 122 is arranged between every two adjacent corrugations 23 of the roofing material 22. Figure 8 As shown, the multiple sleepers 122 have the same size in the vertical direction, and the upper surfaces 111 of the multiple sleepers 122 are located in the same plane to stably support the guide rail 110. In addition, the height of the upper surfaces 111 of the multiple sleepers 122 in the vertical direction is higher than the height of the corrugations 23 of the roofing material 22 in the vertical direction to avoid direct contact between the guide rail 110 and the roofing material 22, thereby avoiding damage to the roofing material 22.

[0078] Furthermore, if Fig. 9 As shown, the upper side of the sleeper 122 is detachably connected to the guide rail 110 by fasteners 260. The lower side of the sleeper 122 is fixed to the purlin of the roof support 24 of the factory building by dovetail nails 1221 and glue, so that the purlin of the roof support 24 is used to effectively support the guide rail 110, avoiding the problem of low support strength of the roof 20 for the guide rail 110 due to the low structural strength of the roofing material 22. At the same time, the sleeper 122 is arranged between the guide rail 110 and the roofing material 22, which also protects the paint surface of the roofing material 22.

[0079] Therefore, the guide rail 110 in the transport device 10 of the present invention is suitable for T-shaped color steel tile roofs, and the sleepers 122 are used to realize the connection between the guide rail 110 and the roof support 24 of the factory building, thereby improving the supporting strength of the roof 20 for the guide rail 110.

[0080] In some embodiments, the upper surface 111 of the guide rail 110 in the transport device 10 of the present invention can be coated with lubricating material, such as butter grease, to achieve anti-corrosion and lubrication effects. In addition, each contact surface of the pulley assembly 210 and the bolt rod surface of the pulley through bolt 216 of the pulley assembly 210 can also be coated with lubricating material, such as butter grease, to further ensure the anti-corrosion and lubrication effects on the roller skates.

[0081] In some embodiments, Figure 6 and Figure 7 As shown, the guide rail assembly 100 in the transport device 10 of the present invention also has a plurality of limit blocks 130. Specifically, each guide rail 110 is provided with limit blocks 130 at both ends in the length direction to limit the maximum displacement of the platform assembly 200 along the guide rail 110. Thus, when the platform assembly 200 in the transport device 10 of the present invention moves along the guide rail 110, after moving to either end of the guide rail 110 in the length direction, the pulley assembly 210 contacts the limit blocks 130, thereby stopping further sliding, preventing the platform assembly 200 from falling off the extended end of the guide rail 110, thereby improving the safety of the transport device 10.

[0082] In some embodiments, Figure 10 to Figure 14As shown, the platform assembly 200 in the transport device 10 of the present invention may further include two extended cross beams 240 and at least one extended longitudinal beam 250. Specifically, the two extended cross beams 240, each of which extends parallel to the length direction of the platform cross beam 220, are configured to be pulled out or retracted a certain distance along the length direction of the platform cross beam 220 and detachably connected to a plurality of platform longitudinal beams 230 through fasteners 260 to adjust the length of the platform assembly 200. Each extended longitudinal beam 250 is arranged perpendicular to the extended cross beam 240 and detachably connected to one end of each of the two extended cross beams 240 extending out of the platform cross beam 220, and the upper surface 111 of the extended longitudinal beam 250 is flush with the upper surface 111 of the platform longitudinal beam 230, so as to carry the components to be assembled together with the platform longitudinal beam 230. It should be noted that the platform beam 220 can be a metal rod extending in the lateral direction of the roof 20, the length direction of the platform beam 220 is the extension direction of the platform beam 220, and the length of the platform assembly 200 is the size of the platform beam 220 in the extension direction.

[0083] That is, the platform assembly 200 in the transport device 10 of the present invention may include a platform body and an extension portion that can be extended or retracted relative to the platform body. The platform body is composed of a platform cross beam 220 and a platform longitudinal beam 230, and the extension portion is composed of an extension cross beam 240 and an extension longitudinal beam 250. Specifically, the extension longitudinal beam 250 and the platform longitudinal beam 230 may be metal rods of the same regularity, and are arranged in parallel and spaced apart in the transverse direction of the roof 20.

[0084] like Fig.10 and Fig.11 As shown, when the platform assembly 200 is in the unextended state, the extension portion is completely retracted into the platform body, the extension end of the extension beam 240 on the side away from the handrail beam 330 is flush with the extension end of the platform beam 220 on the side away from the handrail beam 330, and the distance between the extension longitudinal beam 250 and the adjacent platform longitudinal beam 230 is less than the width of the extension longitudinal beam 250.

[0085] like Fig.12 and Fig.13As shown, when the platform assembly 200 is in the extended state, the extension portion extends from the platform body, and the ratio of the distance between the extension end of the extension beam 240 on the side away from the handrail beam 330 and the extension end of the platform beam 220 on the side away from the handrail beam 330 to the length of the platform beam 220 is selected from any value between 0.1 and 0.5, so as to increase the length of the platform assembly 200. For example, when the platform assembly 200 is in the extended state, the ratio of the distance between the extension end of the extension beam 240 on the side away from the handrail beam 330 and the extension end of the platform beam 220 on the side away from the handrail beam 330 to the length of the platform beam 220 is selected from any value between 0.1 and 0.3. In a specific embodiment, when the platform assembly 200 is in the extended state, the ratio of the distance between the extended end of the extension beam 240 on the side away from the handrail beam 330 and the extended end of the platform beam 220 on the side away from the handrail beam 330 to the length of the platform beam 220 can be 0.2, so as to ensure the structural stability of the platform assembly 200 while increasing the length of the platform assembly 200.

[0086] like Fig.14 As shown, the dimension of the extension part in the longitudinal direction is smaller than the dimension of the platform body in the longitudinal direction, and the extension beam 240 is arranged on the inner side of the plurality of adjacent platform beams 220, thereby effectively utilizing the inner space of the platform body. The height of the upper surface 111 of the extension beam 240 in the vertical direction is the same as the height of the platform beam 220 in the vertical direction, so as to ensure that the upper surface 111 of the extension longitudinal beam 250 is flush with the upper surface 111 of the platform longitudinal beam 230, thereby improving the surface flatness of the platform assembly 200, so as to ensure the transportation efficiency of the transportation device 10.

[0087] In some embodiments, Figure 3 , Figure 4 , Fig.15 and Fig.16 As shown, the propulsion assembly 300 may further include a column 310. The column 310 is vertically arranged with the platform assembly 200, and the upper and lower ends of the column 310 are detachably connected to the handrail beam 330 and the platform assembly 200 through the connecting piece 320, so that the handrail beam 330 is located above the platform assembly 200. Specifically, the connecting piece 320 includes a bottom connecting piece 321 and a top connecting piece 322. The lower end of the column 310 is detachably connected to the platform cross beam 220 through the bottom connecting piece 321, and the upper end of the column 310 is detachably connected to the handrail beam 330 through the top connecting piece 322.

[0088] Therefore, the handrail beam 330 is located above the platform assembly 200, which increases the overall height of the transportation device 10, facilitates manual pushing of the handrail beam 330 to drive the platform assembly 200 to move along the guide rail 110, and ensures the convenience of the platform assembly 200 moving along the guide rail 110.

[0089] In some embodiments, Fig.15 and Fig.16 As shown, the propulsion assembly 300 may further include a locking rod 340. The locking rod 340 is detachably connected to the column 310 via a locking member 350, and is configured such that during the use of the transport device 10, both upper and lower ends of the locking rod 340 are connected to the column 310, so that the locking rod 340 is installed on the column 310, and when the transport device 10 is not in use, one end of the locking rod 340 can be connected to the column 310 and the other end can be connected to the guide rail 110, so as to lock the transport device 10. In other words, the locking rod 340 has a first working position in which the locking rod 340 is parallel to and closely disposed with the column 310, and a second working position in which both ends are connected to the column 310 and the guide rail 110, respectively. Fig.15 As shown, during the use of the transport device 10, the locking rod 340 is in the first working position, the locking rod 340 is vertically arranged and the upper and lower ends of the locking rod 340 are connected to the column 310 through the locking member 350 to be completely retracted. Fig.16 As shown, when the transport device 10 is not in use, the locking rod 340 is tilted and the upper and lower ends are connected to the column 310 and the guide rail 110 through the locking member 350 respectively, so as to fix the platform assembly 200 on the guide rail 110.

[0090] Thus, the locking rod 340 can be fixed to the back of the column 310 of the propulsion assembly 300 when not in use, and the locking piece can be disassembled and fixed to the guide rail 110 when in use. When the transport device 10 is not in use, the platform assembly 200 can be locked by the locking rod 340 and the locking piece 350 before people can leave, thereby avoiding accidents caused by the platform assembly 200 continuing to slide along the guide rail 110, thereby improving the safety of the transport device 10.

[0091] In some embodiments, Figures 17 to 22 As shown, the transport device 10 of the present invention can also be used in the process of transporting the components to be assembled on the assembled photovoltaic bracket 30 on the roof 20, and part of the structure on the photovoltaic bracket 30 is used as the guide rail 110 to transport materials and photovoltaic panels. Fig.17 As shown, the transport device 10 of the present invention may only include the platform assembly 200 and the propulsion assembly 300 .

[0092] In this embodiment, if Figures 17 to 22 As shown, the guide rail 110 can be a purlin 31 in a photovoltaic bracket 30 arranged on the roof 20. The platform assembly 200 is arranged on any two adjacent and parallel purlins 31 so that the transport device 10 can move on the photovoltaic bracket 30. It should be noted that a photovoltaic panel needs to be laid on the top of the photovoltaic bracket 30, that is, the photovoltaic bracket 30 is used to support the photovoltaic panel. In addition, the photovoltaic panel can generate electricity using the photovoltaic effect to supply power to the user.

[0093] The platform assembly 200 may include a plurality of pulley assemblies 210, a plurality of platform beams 220, and a plurality of platform longitudinal beams 230. Specifically, each of the plurality of platform beams 220 is disposed perpendicularly to the purlin 31. The plurality of pulley assemblies 210 are disposed at the bottom of the platform beams 220, and the bottom of each platform beam 220 is detachably connected to a plurality of spaced pulley assemblies 210. Each of the plurality of platform longitudinal beams 230 is disposed perpendicularly to the platform beams 220 and is detachably connected to the plurality of platform beams 220, respectively, for carrying components to be assembled.

[0094] The propulsion assembly 300 is arranged on the platform assembly 200 and has a column 310 and a handrail beam 330. The column 310 is vertically arranged with a plurality of platform beams 220 and a plurality of platform longitudinal beams 230. The upper end of the column 310 is detachably connected to the handrail beam 330 through a top connector 322, and the lower end of the column 310 is detachably connected to the platform assembly 200, so that the handrail beam 330 is located above the platform assembly 200. The lower end of the column 310 is detachably connected to the column bottom beam 323 through a bottom connector 321, and the column bottom beam 323 is located above the platform beam 220 and is detachably connected to the platform beam 220 through a fastener 260. The handrail beam 330 is used to drive the platform assembly 200 to move along the guide rail 110 under the action of an external force. That is, the transport device 10 of the present invention includes a transport vehicle constructed by a platform assembly 200 and a propulsion assembly 300, and the transport vehicle is provided with a handrail beam 330 that can be used for manual pushing.

[0095] Therefore, the transportation device 10 of the present invention utilizes the purlin 31 in the photovoltaic bracket 30 as the guide rail 110, and uses a transport vehicle that cooperates with the guide rail 110 to realize the transportation of photovoltaic components such as materials and photovoltaic panels. After the construction of the photovoltaic bracket 30 is completed, the photovoltaic panels and materials can be quickly transported and installed, thereby improving the overall construction efficiency.

[0096] That is to say, firstly, the transport device 10 of the present invention can firstly lay the guide rail 110 on the roofing material 22 of the roof 20, and use the transport vehicle constructed by the platform component 200 and the propulsion component 300, so as to realize the primary transport of photovoltaic components such as the photovoltaic bracket 30 when the photovoltaic bracket 30 is not built on the roof 20. Secondly, the transport device 10 of the present invention can again use the purlin 31 in the built photovoltaic bracket 30 as the guide rail 110, and use the transport vehicle constructed by the platform component 200 and the propulsion component 300 again, so as to realize the secondary transport of photovoltaic components such as photovoltaic panels and materials when the photovoltaic bracket 30 is built on the roof 20. So far, the transport device 10 of the present invention can be applied to both the construction process of the photovoltaic bracket 30 and the construction process of the sun room composed of the photovoltaic panel and the photovoltaic bracket 30, which further improves the versatility of the transport device 10.

[0097] In a specific embodiment, the transport device 10 of the present invention can be provided with two parallel platform beams 220 and two platform longitudinal beams 230 to form a platform assembly 200, and two parallel purlins 31 are selected as guide rails. Two pulley assemblies 210 are provided at the bottom of each platform beam 220, and the distance D between the two pulley assemblies 210 on each platform beam 220 can be set according to the distance L between the two parallel purlins 31. Specifically, the distance D between the two pulley assemblies 210 on each platform beam 220 can be the same as the distance L between the two parallel purlins 31. Thus, the two pulley assemblies 210 on each platform beam 220 correspond to the two guide rails 110 one by one. Therefore, the transport device 10 of the present invention can adjust the length of the platform beam 220 and the distance D between the two pulley assemblies 210 on each platform beam 220, so that the platform assembly 200 can be applicable to two parallel purlins 31 with different distances L, thereby further improving the versatility of the transport device 10.

[0098] In some embodiments, Fig.19 and Fig. 20 As shown, the purlin 31 in the built photovoltaic bracket 30 can be arranged horizontally. Specifically, the photovoltaic bracket 30 may include a horizontally arranged purlin 31 and a mounting member 32 for detachably mounting the purlin 31 on the roofing material 22 of the roof 20. The upper end of the mounting member 32 is detachably connected to the purlin 31 in the photovoltaic bracket 30, and the lower end of the clamp 121 is detachably connected to the corrugation 23 of the roofing material 22.

[0099] In other embodiments, Fig.21 and Fig. 22As shown, the purlin 31 in the built photovoltaic support 30 can also be set at an angle to improve the power generation efficiency of the photovoltaic panel. Correspondingly, the bottom of the platform assembly 200 has a main pulley 211 and an auxiliary pulley 212 that are vertical in the axial direction. Specifically, the auxiliary pulley 212 is arranged on the side of the main pulley 211 adjacent to the ridge line 21 in the axial direction. After the transport device 10 is placed on the purlin 31 in the photovoltaic support 30, the main pulley 211 is slidably connected to the upper surface 111 of the purlin 31, and the auxiliary pulley 212 is slidably connected to the side surface 112 of the purlin 31 that is inclined upward, so as to support the platform assembly 200 to be inclined on the purlin 31.

[0100] Therefore, the transportation device 10 of the present invention can be placed obliquely on the purlin 31 in the photovoltaic bracket 30, and the auxiliary pulley 212 can provide auxiliary support while performing auxiliary sliding, thereby preventing the platform assembly 200 from falling off the purlin 31 in the photovoltaic bracket 30, and further improving the safety of the transportation device 10.
