[0031] In the related art, photovoltaic equipment such as the grid-connected box of a photovoltaic system can mostly be installed by wall-mounted installation. By fixing the photovoltaic equipment on the wall or frame of the assembly environment and placing the photovoltaic equipment at a certain height from the ground, it can be beneficial to reduce the floor space of the photovoltaic system and facilitate the connection and wiring of photovoltaic equipment such as the grid-connected box and photovoltaic modules. However, when photovoltaic equipment is installed by wall-mounted installation, it usually requires two or more construction workers to cooperate in the installation. The photovoltaic equipment is lifted to a certain height from the ground by manual handling, and then other construction workers are asked to fix the photovoltaic equipment on the wall or frame. The volume and weight of photovoltaic equipment are mostly large, resulting in greater difficulty in the operation of transporting and installing the photovoltaic equipment and lower assembly efficiency. In response to the above problems, the present application proposes a transportation device 100.

[0032] See also Figures 1 to 7 In one embodiment of the present application, the transport device 100 includes a support frame 10, a bracket 30 and a lifting mechanism 50. The bracket 30 is connected to the support frame 10, and the bracket 30 has a load-bearing platform; the lifting mechanism 50 is installed on the support frame 10 and connected to the bracket 30. The lifting mechanism 50 drives the bracket 30 to rise and fall, and is used to limit and fix the bracket 30 relative to the support frame 10 when the bracket 30 moves to any height.

[0033] It is understood that in a photovoltaic system, the photovoltaic modules can be installed at a certain height above the ground under the support and fixation of the photovoltaic bracket, which is conducive to better reducing the obstruction of light on the photovoltaic modules by obstructions, while also allowing a certain amount of space under the photovoltaic modules, thereby further reducing the footprint of the photovoltaic system. In the photovoltaic system, the photovoltaic modules need to be connected to the photovoltaic equipment such as the grid-connected box 200 for electrical wiring, so that the electricity converted by the photovoltaic modules can be more stably and reliably output to the power grid, ensuring the stable operation of the photovoltaic system. In this case, if the photovoltaic system is equipped with a photovoltaic bracket with good load-bearing capacity to install the photovoltaic modules, or if the photovoltaic system is installed near a building, the photovoltaic equipment such as the grid-connected box 200 can be installed and fixed on the frame of the photovoltaic bracket or on the building wall, and the photovoltaic equipment is installed at a certain height above the ground. This is conducive to better installing the photovoltaic equipment such as the grid-connected box 200 at the same height as the photovoltaic modules, facilitating the routing of transmission cables, and avoiding the photovoltaic equipment occupying ground space, so that the photovoltaic system can be better installed in a variety of environments.

[0034] In the present application, the photovoltaic system can use the transport device 100 to realize the quick lifting and assembly of photovoltaic equipment such as the grid-connected box 200, thereby better improving the assembly efficiency of the photovoltaic system. The transport device 100 may include a support frame 10, a bracket 30 and a lifting mechanism 50. The support frame 10 may be provided with a certain counterweight or may adopt a frame structure similar to a triangle to ensure the overall structural anchoring effect of the transport device 100 during the handling process, and the bracket 30 may be a frame structure with a certain load-bearing capacity. A corresponding bearing platform for supporting photovoltaic equipment such as the grid-connected box 200 may be formed on the bracket 30. By using the lifting mechanism 50 to connect the support frame 10 and the bracket 30, the lifting mechanism 50 can be used to drive the bracket 30 to move up and down on the support frame 10, so that the photovoltaic equipment supported on the bearing platform of the bracket 30 can be lifted up to a certain height, thereby ensuring the stable off-ground installation of the photovoltaic equipment on the frame or building wall.

[0035] The bracket 30 can be connected to the support frame 10 by rollers or guide rails. The lifting structure can be a lifting mechanism, a transmission belt lifting mechanism, or a lifting rod mechanism that connects the bracket 30 and the support frame 10. During the operation of the lifting mechanism 50, a certain force can be applied to the bracket 30 to achieve stable lifting of the bracket 30. The lifting mechanism 50 can be provided with a ratchet self-locking structure in the lifting wheel group or the transmission wheel group, or a self-locking structure can be provided in the drive motor. When the lifting mechanism 50 drives the bracket 30 to move to any height, the self-locking limit function of the lifting mechanism 50 can be utilized, allowing the bracket 30 to stop at any height at any time. Therefore, when the transport device 100 lifts the photovoltaic equipment such as the grid-connected box 200 to the corresponding installation height, the bracket 30 is fixed relative to the support frame 10, ensuring stable and reliable assembly of the photovoltaic equipment.

[0036] Therefore, during the assembly process of the photovoltaic system, construction workers can place photovoltaic equipment such as the grid-connected box 200 on the bearing platform of the bracket 30, and move the transport device 100 to the bottom of the location where the photovoltaic equipment is to be installed. Then, the lifting mechanism 50 is used to drive the bracket 30 to move up and down on the support frame 10 to the corresponding installation position. At this time, the lifting mechanism 50 is self-locked and fixed, and the bracket 30 is maintained at the current installation position. The construction workers can then directly operate the fasteners to install and fix the photovoltaic equipment on the frame or wall. After the installation is completed, the lifting mechanism 50 can be operated to lower the bracket 30 and then install other photovoltaic equipment. There is no need for manual transportation and lifting of photovoltaic equipment, which effectively reduces the assembly workload and difficulty of the photovoltaic system, reduces the manpower required during installation and construction, and is conducive to better improving the overall assembly efficiency of the photovoltaic system, and further improves the practicality and reliability of the transport device 100.

[0037] In one embodiment of the present application, by using a transport device 100 to carry and lift photovoltaic equipment such as a grid-connected box 200 during the assembly process of the photovoltaic system, the lifting mechanism 50 can be used to drive the lifting and lowering of the bracket 30 and the lifting self-locking limit, so that the transport device 100 can stably lift and fix the photovoltaic equipment at a certain height above the ground for installation. There is no need for manual lifting of heavy photovoltaic equipment during the assembly process, which effectively reduces the difficulty and workload of the assembly construction of the photovoltaic system, realizes a more convenient assembly and construction of the photovoltaic system, improves the assembly efficiency of the photovoltaic system, and further improves the practicality and reliability of the transport device 100.

[0038] See Figure 1 、 Figure 5 and Figure 7 In one embodiment of the present application, the lifting mechanism 50 includes a hoist 51, a movable pulley 53 and a traction chain 55. The hoist 51 is connected to the support frame 10; the movable pulley 53 is connected to the bracket 30 and is spaced apart from the hoist 51; the traction chain 55 transmits and connects the hoist 51 and the movable pulley 53.

[0039] In this embodiment, the lifting mechanism 50 can be configured as a lifting mechanism that cooperates with a hoist 51 and a movable pulley 53. The hoist 51 can be a hand hoist, an electric hoist, or a hydraulic hoist, etc. A ratchet self-locking structure is integrated into the hoist 51. The movable pulley 53 and the bracket 30 can be lifted and lowered by manually pulling a traction chain 55, or the traction chain 55 can be driven by a motor or a hydraulic device to lift and lower the pulley 53 and the bracket 30. When the traction chain 55 stops moving under the self-locking action of the ratchet of the hoist 51, the bracket 30 can be fixed by the self-locking limit of the hoist 51, thereby ensuring that the bracket 30 carrying the photovoltaic device is installed at a certain height. The use of the lifting mechanism 50 with the hoist 51 can make the overall structure of the transport device 100 more concise, facilitate the production and assembly of the transport device 100, and achieve simpler operation and control, further improving the practicality and reliability of the transport device 100.

[0040] See Figure 5 and Figure 7 In one embodiment of the present application, the support frame 10 includes an anchoring bracket 11 and an escalator 13, the bracket 30 is connected to the anchoring bracket 11; the escalator 13 is connected to the anchoring bracket 11 and is arranged at an angle to the anchoring bracket 11, and the bearing platform is located on the side of the anchoring bracket 11 facing away from the escalator 13.

[0041] In this embodiment, the support frame 10 can use the anchor bracket 11 to anchor the lifting mechanism 50 and the bracket 30, ensuring that the transport device 100 can stably lift and install the photovoltaic equipment. By connecting and installing an escalator 13 on one side of the anchor bracket 11, the escalator 13 can be tilted relative to the ground and installed at an angle to the anchor bracket 11. This helps the escalator 13 and the anchor bracket 11 form a triangular support structure, thereby further improving the overall structural stability of the support frame 10. After the construction worker operates the lifting mechanism 50 to lift the bracket 30 and the photovoltaic equipment, the escalator 13 can be used to climb to the same height as the photovoltaic equipment. This allows the construction worker to more conveniently install and secure the photovoltaic equipment to the frame or wall. Furthermore, the transport device 100 can integrate functions such as lifting workpieces and assisting in climbing and installation, eliminating the need for construction workers to use additional tooling to perform assembly work at a higher location, further improving the practicality and structural reliability of the transport device 100.

[0042] See Figure 6 and Figure 7 In one embodiment of the present application, the escalator 13 is provided with at least two pairs of hook rods 113, and the at least two pairs of hook rods 113 are spaced apart along the extension direction of the escalator 13, one end of the hook rod 113 is rotatably connected to the escalator 13, and the other end of the hook rod 113 is clamped to the anchor bracket 11.

[0043] In this embodiment, the escalator 13 can adopt a detachable structure on the anchor bracket 11, so that the transport device 100 can better remove the escalator 13 when it is not needed to be installed or stored with the help of the escalator 13, thereby reducing the overall storage volume and occupied space of the transport device 100, and further improving the practicality and structural reliability of the transport device 100.

[0044] Among them, the hanging rods 113 can be installed on the two opposite sides of the escalator 13 respectively. At this time, the two hanging rods 113 located at the same height can be set as a pair of hanging rods 113, and two or more pairs of hanging rods 113 can be arranged at intervals along the extension direction of the escalator 13. By utilizing the matching and snap connection between the hanging rods 113 and the anchor bracket 11, the overall connection stability of the anchor bracket 11 and the escalator 13 can be better guaranteed, so that construction workers can better use the transportation device 100 to realize the convenient installation of photovoltaic equipment. The hook rod 113 can be rotatably connected to the side wall of the escalator 13 at one end by means of a rotating shaft or a bolt, and a boss is provided on the anchor bracket 11 to engage with the clip at the other end of the hook rod 113. The clip-on installation and fixing method can be used to better improve the convenience of disassembly and assembly of the anchor bracket 11 and the escalator 13. At the same time, after the escalator 13 is dismantled, the hook rod 113 can be rotated and stored on the side wall of the escalator 13, effectively reducing the space occupied by the escalator 13 when it is stored, and further improving the practicality of the transportation device 100.

[0045] See Figure 2 and Figure 4 In one embodiment of the present application, the bracket 30 includes a sliding bracket 31 and a load-bearing bracket 33. The sliding bracket 31 is connected to the support frame 10, and the lifting mechanism 50 is connected to the sliding bracket 31; the load-bearing bracket 33 is connected to the sliding bracket 31, and the load-bearing bracket 33 has a load-bearing platform.

[0046] In this embodiment, the sliding bracket 31 can be combined with the supporting bracket 33 to form a right-angled frame structure, and the supporting bracket 33 can be raised and exposed on one side of the support frame 10, so that the supporting bracket 33 can better form a load-bearing platform on the side of the support frame 10 to support photovoltaic equipment such as the grid-connected cage 200. By providing a sliding structure on the sliding bracket 31 that cooperates with the support frame 10, and by causing the lifting mechanism 50 to drive the sliding bracket 31 to move up and down on the support frame 10, the supporting bracket 33 can be raised and lowered with the sliding bracket 31, so that the photovoltaic equipment supported on the supporting bracket 33 can be stably lifted and installed. The sliding bracket 31 and the supporting bracket 33 can be separately formed by combining high-strength steel structures, or they can be integrally formed of a plate structure with high load-bearing performance. This ensures that the bracket 30 has a good load-bearing support function, ensuring that the transport device 100 can stably lift the photovoltaic equipment, further improving the overall structural stability and reliability of the transport device 100.

[0047] See Figure 2 and Figure 3 In one embodiment of the present application, the support bracket 33 is rotatably connected to the sliding bracket 31, and the transport device 100 has a transport state and a storage state. When the transport device 100 is in the transport state, the support bracket 33 is arranged at an angle to the sliding bracket 31. When the transport device 100 is in the storage state, at least a portion of the support bracket 33 overlaps with the sliding bracket 31 and is stored within the support frame 10.

[0048] In this embodiment, the supporting bracket 33 can be provided with a sleeve or U-shaped clip on the side facing the sliding bracket 31, and a rotating shaft can be provided on the sliding bracket 31. This allows one side of the supporting bracket 33 to be rotatably mounted on the sliding bracket 31, allowing the supporting bracket 33 to rotate a certain angle around the rotating shaft on the sliding bracket 31. In this case, a certain cavity can be formed in the middle of the supporting bracket 33, so that part of the structure of the sliding bracket 31 is smaller than the size of this cavity. When the supporting bracket 33 rotates toward the sliding bracket 31, part of the structure of the sliding bracket 31 can be accommodated in the cavity of the supporting bracket 33, so that the sliding bracket 31 and the supporting bracket 33 can overlap to form a plate structure of a certain thickness. Furthermore, when the transport device 100 is in a storage state and does not need to perform transport and installation operations, the load-bearing bracket 33 can be rotated toward the sliding bracket 31 by a certain angle, so that the load-bearing bracket 33 can overlap with the sliding bracket 31 and be stored in the support frame 10, which is conducive to better reducing the overall structural volume of the transport device 100 when stored, reducing the space occupied by the transport device 100 when stored, facilitating the storage and placement of the transport device 100, and further improving the practicality of the transport device 100. When the transport device 100 needs to perform transport and installation operations and is in a transport state, the load-bearing bracket 33 can be rotated by a certain angle in a direction away from the sliding bracket 31, so that the load-bearing bracket 33 can maintain a certain angle with the sliding bracket 31, ensuring that the load-bearing bracket 33 more stably uses the load-bearing platform to support photovoltaic equipment such as the grid-connected box 200, ensuring the stable operation of the transport device 100, and further improving the structural stability and reliability of the transport device 100.

[0049] The supporting bracket 33 and the sliding bracket 31 are arranged to rotate relative to each other to realize the folding and storage of the bracket 30. When the transport device 100 is in the transport state, a limiting protrusion can be set on the rotating shaft of the sliding bracket 31 to support the supporting bracket 33, or the supporting bracket 33 can be rotated to a certain angle and then abut against the side wall of the sliding bracket 31, thereby preventing the supporting bracket 33 from rotating downward to be in the same vertical plane as the sliding bracket 31, so that the supporting bracket 33 can support the photovoltaic equipment more stably and reliably.

[0050] See Figure 2 and Figure 4 In one embodiment of the present application, the sliding bracket 31 is provided with a limit block 311, which is connected to the sliding bracket 31 and limits the support of the bearing bracket 33 when the transportation device 100 is in the storage state.

[0051] In this embodiment, a limit block 311 with a certain length can be installed at the bottom of the sliding bracket 31, so that the limit block 311 can be exposed below the supporting bracket 33 when the transport device 100 is in the transport state, and then the supporting bracket 33 can be rotated to a certain angle and abut against the limit block 31 when it forms a certain angle structure with the sliding bracket 31, so that the limit block 311 can support the supporting bracket 33 to ensure that the supporting bracket 33 and the bottom of the sliding bracket 31 are on the same plane, and then the limit block 311 can be used to limit the excessive rotation of the supporting bracket 33 to ensure that the supporting bracket 33 stably supports the photovoltaic equipment.

[0052] Among them, the limit block 311 can be rotatably installed at the bottom of the limit block 311, so that the sliding bracket 31 can move the limit block 311 to limit and support the supporting bracket 33 when the transportation device 100 is adjusted to the transportation state, and when the transportation device 100 needs to be adjusted to the storage state, the limit block 311 can be moved to overlap with the sliding bracket 31, thereby reducing the exposed structure of the transportation device 100 when it is stored, effectively reducing the space occupied by the transportation device 100 when it is stored, and further improving the practicality and reliability of the transportation device 100.

[0053] See Figures 2 to 4 In one embodiment of the present application, the supporting bracket 33 is provided with a fixing member 331, and the fixing member 331 is provided on the supporting platform and is used to limit and fix the photovoltaic device.

[0054] In this embodiment, the transport device 100 can be equipped with a fixing part 331 on the load-bearing bracket 33. The fixing part 331 can be a limit baffle or a limit column protruding from the load-bearing platform, or the fixing part 331 can adopt a strap structure for binding and connecting the load-bearing platform and the photovoltaic equipment, or the fixing part 331 can adopt a limit pin structure that cooperates with the base ear plate of the photovoltaic equipment, etc., so that the transport device 100 can use the fixing part 331 to limit and fix the photovoltaic equipment when supporting and transporting photovoltaic equipment such as the grid-connected box 200, effectively preventing the photovoltaic equipment from detaching from the load-bearing platform during the lifting process, ensuring the stable lifting and installation of the photovoltaic equipment by the transport device 100, and further improving the practicality and reliability of the transport device 100.

[0055] See Figures 2 to 4 In one embodiment of the present application, the fixing member 331 includes a first clamp 3311 and a second clamp 3313. The first clamp 3311 is connected to the supporting bracket 33 and protrudes from the supporting platform. The second clamp 3313 is movably connected to the supporting bracket 33 and is used to clamp and fix the photovoltaic device with the first clamp 3311.

[0056] In this embodiment, the fixing member 331 may include a first clamping block 3311 and a second clamping block 3313. By setting the protrusions of the first clamping block 3311 and the second clamping block 3313 on the carrying platform, the fixing member 331 can clamp and fix the photovoltaic equipment on the carrying platform to ensure the stable lifting and transportation of the photovoltaic equipment on the bracket 30. Among them, the first clamp 3311 can be fixedly installed on the carrying platform, and the second clamp 3313 can be movably connected to the carrying bracket 33, and the second clamp 3313 can be moved or rotated on the carrying bracket 33, and then the photovoltaic device can be placed on the carrying platform to abut the first clamp 3311, and then the second clamp 3313 can be moved close to the first clamp 3311 so that the second clamp 3313 and the first clamp 3311 respectively abut against the opposite sides of the photovoltaic device, thereby realizing that the fixing member 331 can stably clamp and fix photovoltaic devices of various sizes, so that the transportation device 100 can be adapted to the assembly of various photovoltaic devices; at the same time, after the photovoltaic device is lifted and transported to the corresponding installation position, the position of the second clamp 3313 can be adjusted to more conveniently loosen the fixation of the photovoltaic device, so that the fixing member 331 can avoid the photovoltaic device during installation, further improving the assembly operation stability and reliability of the transportation device 100.

[0057] See Figure 2 and Figure 4 In one embodiment of the present application, the supporting bracket 33 is provided with a transmission roller 333, and the transmission roller 333 is rotatably provided on the supporting platform.

[0058] In this embodiment, the transport device 100 can be equipped with a rotatable transmission roller 333 on the carrying platform so that photovoltaic equipment such as the grid-connected box 200 can abut against the transmission roller 333 when placed on the carrying platform. This is beneficial for utilizing the rolling contact between the transmission roller 333 and the photovoltaic equipment to reduce the friction between the photovoltaic equipment and the carrying bracket 33, reduce the chassis wear of the photovoltaic equipment, and at the same time make it easier to move the photovoltaic equipment to the carrying platform, and more easily move it from the carrying platform to the corresponding assembly position for installation, thereby better reducing the obstacles encountered during the assembly of the photovoltaic equipment and further improving the practicality and reliability of the transport device 100.

[0059] See Figure 2 In one embodiment of the present application, the support frame 10 includes a guide column 111 , and a guide wheel 313 is provided on the side wall of the bracket 30 , and the guide wheel 313 is slidably connected to the guide column 111 .

[0060] In this embodiment, by providing guide wheels 313 on the side walls of the bracket 30 to slide in cooperation with the guide posts 111 of the support frame 10, the bracket 30 can be better guided and lifted on the support frame 10, ensuring stable lifting of the bracket 30. The guide wheels 313 can have a U-shaped baffle structure corresponding to the width of the guide posts 111 or a sleeve corresponding to the size of the guide posts 111, so that the guide wheels 313 can cooperate with the guide posts 111 to limit position, preventing the guide wheels 313 from deviating on the guide posts 111, so that the bracket 30 can be lifted and lowered in a directional manner on the support frame 10 along the extension direction of the guide posts 111. This helps to better prevent the bracket 30 from falling off the support frame 10 during the lifting process, ensures stable lifting of the photovoltaic equipment by the transport device 100, and further improves the structural stability and reliability of the transport device 100.

[0061] See Figure 1 and Figure 5 In one embodiment of the present application, the transport device 100 further includes a walking mechanism 70 , which is connected to the support frame 10 and / or the bracket 30 and is used to drive the transport device 100 to move.

[0062] In this embodiment, the walking mechanism 70 can be a trolley that supports the support frame 10, or a trolley that supports the support frame 10 and the bracket 30, or a movable wheel set installed on the support frame 10 or the bracket 30. Under the action of the walking mechanism 70, the transportation device 100 can make certain moving movements in the installation environment, and then the transportation device 100 can load the photovoltaic equipment at the placement location of the photovoltaic equipment such as the grid-connected box 200, and then carry the photovoltaic equipment to the corresponding installation location to lift the photovoltaic equipment for installation, so that the transportation device 100 can achieve more flexible transportation and assembly operations, further improving the practicality and operational convenience of the transportation device 100.

[0063] See Figure 1 and Figure 5 In one embodiment of the present application, the walking mechanism 70 includes a first walking wheel 71 and a second walking wheel 73 , the first walking wheel 71 is connected to the support frame 10 , and the second walking wheel 73 is connected to the bracket 30 .

[0064] In this embodiment, the travel mechanism 70 may include a first travel wheel 71 provided on the support frame 10 and a second travel wheel 73 provided on the bracket 30, so that the cooperation of the first travel wheel 71 and the second travel wheel 73 can better ensure the stable movement of the transport device 100, further improving the overall structural stability and reliability of the transport device 100. The first travel wheel 71 and the second travel wheel 73 can both be universal wheels, so that the travel mechanism 70 can achieve multi-directional movement. Alternatively, one of the first travel wheel 71 and the second travel wheel 73 can be a universal wheel and the other a fixed wheel, thereby enabling the transport device 100 to achieve more stable movement and improve the operational convenience and stability of the transport device 100. The bracket 30 can be equipped with a support column at the bottom to assemble the second travel wheel 73, ensuring that the bracket 30 and the support frame 10 are at the same height when moving, so that the transport device 100 can more stably and reliably support and transport the photovoltaic equipment.
