[0029] Currently, photovoltaic (PV) modules are installed using ground-mounted scaffolding. Specifically, this involves erecting ground-mounted scaffolding under the PV support system, with installers standing on the scaffolding before installing the PV modules onto the support system. This installation method has the following problems: 1. It requires high-quality terrain and strong foundation bearing capacity in the PV site; 2. The scaffolding is heavy and inconvenient to move; 3. Moving the scaffolding requires multiple people to participate simultaneously.

[0030] Therefore, this embodiment provides a suspended ladder that facilitates the installation of photovoltaic modules, is easy to disassemble and move, reduces the requirements for terrain and ground bearing capacity, and also reduces the need for manpower.

[0031] Please see Figures 1 to 3 A suspended ladder for easy installation of photovoltaic modules includes a ladder frame 1 and treads 2. Two ladder frames 1 are spaced apart, and multiple treads 2 are spaced apart vertically. The two ends of the treads 2 are detachably connected to the two ladder frames 1. The top of the ladder frame 1 is hung on the photovoltaic bracket, and the bottom of the ladder frame 1 is inserted into the ground. In this embodiment, the bottom of the ladder frame 1 is directly inserted into the ground, and the top of the two ladder frames 1 is hung on the photovoltaic bracket, thereby suspending the whole structure on the photovoltaic bracket, reducing the requirements for terrain and ground bearing capacity. By directly hanging the ladder frame 1 on the photovoltaic bracket and setting a detachable connection between the ladder frame 1 and the treads 2, the whole structure can be disassembled and moved in stages after the work is completed, reducing the weight of each transport and the number of personnel involved in each transport, while also facilitating movement.

[0032] Please see Figure 2The ladder frame 1 includes a main beam 11, hooks 12, and plugs 13. Hooks 12 are installed on the top of the main beam 11, and plugs 13 are installed on the bottom of the main beam 11. During operation, hooks 12 are hung on the photovoltaic support, specifically on the uprights of the photovoltaic support, thereby suspending the entire frame on the photovoltaic support and facilitating subsequent disassembly. Plugs 13 are inserted into the ground to fix the ladder frame 1 to the ground, while having low requirements for terrain and ground bearing capacity.

[0033] This embodiment also includes fasteners 3, which are wound around the main beam 11 and the photovoltaic support column for locking. This setup secures the main beam 11 to the column, preventing it from swaying during operation and improving operational safety.

[0034] In other feasible embodiments, a plurality of fasteners 3 are provided, and the plurality of fasteners 3 are spaced apart in the vertical direction to further improve the connecting force for fixing the main beam 11 to the column and prevent the main beam 11 from shaking.

[0035] For example, fastener 3 includes a fastening strip with locking plates installed at both ends. Locking holes are formed on the locking plates, and both the fastening strip and the locking plates are made of stainless steel. During operation, the fastening strip is wrapped around the column and main beam 11, and the two locking plates are pressed against each other. One end of a screw is passed through the two locking holes in sequence, and a nut is screwed onto the other end of the screw and pressed against the locking plates, thereby completing the locking of fastener 3 onto the column and main beam 11.

[0036] Preferably, the locking plate is arranged along the width direction of the fastening strip, thereby ensuring that the screw and nut can lock the column and main beam 11 along the length direction of the fastening strip, that is, ensuring the tightness of the fastening strip wrapped around the column and main beam 11.

[0037] Alternatively, fastener 3 can be a clamp of the appropriate model.

[0038] Please see Figure 2 and Figure 3 The ladder frame 1 also includes a sleeve 14. Specifically, the bottom of the main beam 11 has an opening, and the sleeve 14 is inserted into the bottom opening of the main beam 11. The outer wall of the sleeve 14 is screwed to the inner wall of the main beam 11. Furthermore, a plug 13 is installed at the bottom of the sleeve 14. Through the above structural arrangement, the plug 13 can be extended or retracted relative to the main beam 11. During operation, after the hook 12 is hung on the column, the depth of the plug 13 inserted into the ground can be adjusted by rotating the sleeve 14, thus improving the practicality of this embodiment.

[0039] In other feasible embodiments, an abutment plate 15 is fixed in the middle region of the sleeve 14. The abutment plate 15 is sleeved on the outer wall of the sleeve 14. During operation, after the plug 13 is inserted into the ground, the sleeve 14 is rotated to adjust the abutment plate 15 until it abuts against the ground, thereby expanding the contact area with the ground and improving the stability of the ladder frame 1.

[0040] Preferably, the abutment plate 15 is set horizontally, which can improve its adhesion to the ground and provide support for the ladder frame 1 in the vertical direction, thereby improving the stability of the ladder frame 1.

[0041] Please see Figure 1 In this embodiment, two ladder frames 1 are spaced apart along the first direction, and a number of support members 4 are installed at intervals along one side wall of the main beam 11 in the vertical direction. The first direction is perpendicular to the second direction. Multiple treads 2 correspond one-to-one with multiple support members 4 on each main beam 11. Furthermore, the two ends of the treads 2 are respectively installed on the two main beams 11 and their corresponding support members 4.

[0042] For example, the support member 4 is provided with a number of mounting holes at intervals along the second direction, and the two ends of the pedal 2 are provided with a number of connecting holes corresponding to each other along the second direction. Bolts pass through the mounting holes and the corresponding connecting holes and are fixed with nuts, thereby realizing a detachable connection between the pedal 2 and the support member 4.

[0043] In this embodiment, the footplate 2 is horizontally positioned to ensure that installers can stand stably on it, thus improving safety. Correspondingly, the corresponding support members 4 on the two main beams 11 are at the same height in the vertical direction.

[0044] In other feasible embodiments, a plurality of support members 4 are installed vertically at intervals on both sidewalls of the main beam 11 along the second direction. Some of the pedals 2 correspond one-to-one with the plurality of support members 4 on the same side of each main beam 11, and the remaining pedals 2 correspond one-to-one with the plurality of support members 4 on the other side of each main beam 11. Specifically, the two ends of some pedals 2 are respectively installed on the corresponding support members 4 on the same side of the two main beams 11, and the two ends of the remaining pedals 2 are respectively installed on the corresponding support members 4 on the other side of the two main beams 11. By installing a plurality of support members 4 at intervals on the two opposite sidewalls of the main beam 11, a plurality of pedals 2 are installed on both opposite sides of the main beam 11, so that the installer can stand on the corresponding side in accordance with the installation direction of the photovoltaic module, thereby improving applicability.

[0045] Furthermore, the support member 4 includes a horizontal brace 41 and a diagonal brace 42. One end of the horizontal brace 41 and one end of the diagonal brace 42 are connected to the side wall of the main beam 11 at intervals, and the other end of the horizontal brace 41 is connected to the other end of the diagonal brace 42. The horizontal brace 41 and the diagonal brace 42 are arranged at an included angle. Through the above arrangement, both the horizontal brace 41 and the diagonal brace 42 have connection points with the main beam 11, thereby improving the connection strength between the support member 4 and the main beam 11, and indirectly improving the connection strength between the pedal 2 and the main beam 11. Preferably, both the horizontal brace 41 and the diagonal brace 42 are welded to the main beam 11, further improving the connection strength with the main beam 11.

[0046] The mounting hole is provided on the horizontal support 41, so that the pedal 2 can be connected to the horizontal support 41, so that the pedal 2 can be set horizontally.

[0047] Furthermore, the support member 4 also includes a reinforcing brace 43, the two ends of which are connected to the horizontal brace 41 and the diagonal brace 42 respectively. By setting the reinforcing brace 43, the connection strength between the horizontal brace 41 and the diagonal brace 42 is improved, thereby strengthening the overall strength of the support member 4.

[0048] In this embodiment, the plug 13 is directly inserted into the ground, and the hooks on the top of the two ladder frames 1 are hung on the photovoltaic bracket, thereby suspending the entire structure on the photovoltaic bracket, reducing the requirements on the terrain and ground bearing capacity. By directly hanging the hooks on the top of the two ladder frames 1 on the photovoltaic bracket and setting a detachable connection between the ladder frame 1 and the footboard 2, the entire structure can be disassembled and moved in stages after the operation is completed, reducing the weight of each transport and the number of personnel involved in each transport, while also facilitating movement.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
