[0044] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0047] Photovoltaic modules, as the core part of a solar power generation system, are composed of multiple solar cells connected in series or in parallel, and are mainly used to convert solar energy into electrical energy. When transferring objects to be transported, such as photovoltaic modules, which are usually installed on roofs, exterior walls of buildings, open areas, etc., safety issues are likely to arise if the objects to be transported cannot be limited. In order to achieve the transportation and transfer of objects to be transported, especially the transportation and transfer of photovoltaic modules 300 used on industrial and commercial color steel tile roofs, which have long transportation distances, large quantities of objects to be transported, heavy weights, and sloped transportation tracks, the present application proposes a limiting component 100 and a transportation device 200.

[0048] Reference Figures 1 to 11 The limiting assembly 100 is applied to the transport device 200 and includes a connecting portion 110, a mounting portion 120, and a locking member 130. As a stepless position adjustment limiting mechanism, the limiting assembly 100 achieves circumferential positioning of transported objects of different sizes by adjusting the position of the connecting portion 110 locked to the mounting portion 120, thereby avoiding safety issues caused by ineffective positioning.

[0049] Specifically, the mounting portion 120 is used to be mounted on the transport device 200. The mounting portion 120 is provided with a mounting groove 121, and the connecting portion 110 is slidably disposed in the mounting groove 121. The connecting portion 110 and the mounting groove 121 are slidably connected. By adjusting the connection position of the connecting portion 110 and the mounting groove 121, the position of the transported objects of different sizes can be limited, thereby preventing the transported objects from shifting during transportation and transfer.

[0050] To facilitate operation, the locking member 130 includes an eccentric wheel 131 that can be flexibly switched between a locked position and an unlocked position. In the locked position, the eccentric wheel 131 abuts against the wall of the mounting groove 121 to limit the sliding movement of the connecting portion 110 and the mounting groove 121. In the unlocked position, the eccentric wheel 131 is separated from the wall of the mounting groove 121 to release the sliding restriction on the connecting portion 110 and the mounting groove 121. Using the eccentric wheel 131 for locking and fixing can achieve quick and convenient adjustment of the limit assembly 100 and achieve rapid fixation of the connecting portion.

[0051] When it is necessary to adjust the position of the connecting part 110 on the transport device or to adjust the distance between the connecting part 110 and the transport device 200, the eccentric wheel 131 is switched to the unlocked state. In the unlocked position, the eccentric wheel 131 is separated from the groove wall of the installation groove 121, and the sliding restriction on the connecting part 110 and the installation groove 121 is released, so as to flexibly adjust the distance between the connecting parts 110 of each limiting component 100 provided on the transport device to be suitable for transporting objects of different sizes to be transported, effectively expanding the scope of application of the transport device 200 and improving compatibility and versatility. After completing the position adjustment, the eccentric wheel 131 of the locking member 130 is switched to the locking position. In the locking position, the eccentric wheel 131 abuts against the groove wall of the installation groove 121, and the locking member 130 limits the sliding of the connecting part 110 and the installation groove 121, thereby avoiding the safety hazard caused by the sliding of the connecting part 110 relative to the transportation device 200 when loading or transporting the objects to be transported. It is suitable for long-distance transportation and transfer of objects with large quantities and heavy weights in complex environments with slopes, effectively improving safety.

[0052] The limiting assembly 100 is applied to the transport device 200, referring to Figure 10 、 Figure 11 In some specific embodiments of the present application, a transport device 200 includes a transport assembly 220 and multiple position-limiting assemblies. The transport assembly 220 is used to carry and transfer the object to be transported. The multiple position-limiting assemblies are distributed along the circumference of the transport device 200 to enclose a position-limiting area 210 for securing the object to be transported. The multiple position-limiting assemblies include, but are not limited to, one or more position-limiting assemblies 100 of the embodiments of the present application.

[0053] In order to solve the problem of the transported objects slipping during transportation due to the lack of a limiting function in existing transport devices, the embodiment of the present application adopts multiple limiting components distributed along the circumference of the transport device 200. The multiple limiting components are used in combination, and the limiting area 210 formed by the multiple limiting components is used to limit the circumferential position of the transported objects, so that the transported objects are confined to the limiting area 210 to prevent the transported objects from shifting in position. The size of the limiting area 210 formed by the multiple limiting components is adjusted according to the size of the different transported objects to be transported, so as to be suitable for transporting and transferring a variety of transported objects of different sizes, expand the range of use of the transport device, and reduce safety issues. It is also used to avoid the need to use different transport devices 200 corresponding to the different sizes of transported objects, effectively reducing transportation costs and improving transportation efficiency.

[0054] In order to further optimize the limiting effect, a buffer structure or other structure with further limiting effect can be set on the connecting part 110 as a limiting plate 111. The limiting plate 111 increases the contact area between the connecting part 110 and the photovoltaic components waiting to be transported, thereby optimizing the limiting effect.

[0055] Optionally, the connecting portion 110 includes a first connecting portion 112 and a second connecting portion 113, and the limiting plate 111 includes one or more baffle groups, each baffle group including at least one baffle arranged along the length of the first connecting portion 112. The limiting plate 111 is fixed to the side of the first connecting portion 112 near the object to be transported by screw locking, clamping, welding, etc. The limiting plate 111 is provided with a buffer pad. Specifically, the buffer pad is a rubber buffer pad. The buffer pad serves to buffer and absorb energy, and is used to protect the object to be transported during limited transportation. The provision of the buffer pad can also increase friction, further optimize the limiting effect, and prevent the object from shifting during transportation and transfer.

[0056] Furthermore, the limiting plate 111 is detachably connected to the first connecting portion 112, or the limiting plate 111 is non-detachably connected to the first connecting portion 112. The limiting plate 111 can optionally be configured as one connecting plate, two connecting plates with adjustable angles, a limiting structure with sharp corners, etc. When the limiting plate 111 is configured as one connecting plate, the limiting plate 111 is used to abut against the outer edge of the object to be transported; when the limiting plate 111 is configured as multiple connecting plates hinged to the first connecting portion 112, specifically, in order to increase the contact area between the connecting portion 110 and the object to be transported and further optimize the limiting effect, the limiting plate 111 includes a first connecting plate 1111 and a second connecting plate 1112 hinged to the first connecting portion 112, the angle between the first connecting plate 1111 and the second connecting plate 1112 is adjustable, and the first connecting plate 1111 and the second connecting plate 1112 are hinged to each other. When the connecting plate 1112 is opened to 180° between the two, it is used to be set against the outer edge of the object to be transported; alternatively, the angle between the first connecting plate 1111 and the second connecting plate 1112 is adjusted so that the angle between the two corresponds to the turning angle of the object to be transported, so as to construct the limiting plate 111 into a limiting structure with an angular edge. Specifically, when the angle between the first connecting plate 1111 and the second connecting plate 1112 is 90°, it is used to abut the outer corner position of the object to be transported; the specific structure of the limiting plate 111 can be set according to the actual situation and is not limited here.

[0057] Reference Figure 2 、 Figures 5 to 9 As an example of the present application, the locking member 130 further includes a connecting rod 132 and an adjustment block 134. When the locking member 130 is provided with the connecting rod 132, the connecting portion 110 may optionally be provided with a connecting guide groove 1131, an avoidance groove, a connecting channel, etc., to facilitate the insertion of the connecting rod 132. Specifically, the connecting rod 132 has a first end and a second end that are arranged opposite to each other. The connecting rod 132 is arranged through the mounting groove 121 and the connecting portion 110. The adjustment block 134 is provided at the first end of the connecting rod 132, and the second end of the connecting rod 132 is rotatably connected to the eccentric wheel 131. By locking and fixing the eccentric wheel 131, the limit assembly 100 can be quickly and conveniently adjusted, and the connecting portion can be quickly fixed.

[0058] It can be understood that the connecting rod 132 has a first end and a second end that are oppositely arranged along its length direction. The connecting rod 132 is arranged through the installation groove 121 and the connecting portion 110 to connect the connecting portion 110 and the installation groove 121. A gap is left between the second connecting portion 113 and the groove wall of the installation groove 121. Figure 8 , the eccentric wheel 131 is set against the groove wall of the installation groove 121 when it is in the locked position; Figure 9The eccentric wheel 131 is separated from the groove wall of the mounting groove 121 when in the unlocked position; the gap between the mounting groove 121 and the connecting portion 110 is adjusted by the eccentric wheel 131 to lock the mounting portion 120 and the connecting portion 110 to restrict the sliding of the connecting portion 110; or the connecting portion 110 locked in the mounting groove 121 is released to remove the sliding restriction of the connecting portion 110 and the mounting groove 121.

[0059] In this embodiment, the adjustment block 134 is optionally fixedly connected to the first end of the connecting rod; or the adjustment block 134 is movably connected to the connecting rod 132. When the adjustment block 134 is movably connected to the connecting rod 132, the adjustment block 134 is configured to move closer to the eccentric wheel 131 and abut against the wall of the mounting groove 121, or to move away from the eccentric wheel 131 and separate from the wall of the mounting groove 121.

[0060] Optionally, the first end of the connecting rod 132 is provided with a first thread, and the adjusting block 134 is provided with a second thread, one of the first thread and the second thread is an internal thread and the other is an external thread, the first thread and the second thread are adapted to each other, and the adjusting block 134 is screwed in and out along the connecting rod 132 to achieve a movable connection between the adjusting block 134 and the connecting rod 132; or, the circumferential side of the first end of the connecting rod 132 is provided with a first connecting portion, the circumferential side of the adjusting block 134 is provided with a second connecting portion, one of the first connecting portion and the second connecting portion is a slide groove and the other is a card The connecting piece, the first connecting part and the second connecting part are slidably connected, and the clamping piece is slid along the slide groove to realize the movable connection between the adjustment block 134 and the connecting rod 132; or, the first end of the connecting rod 132 is provided with a movable channel, and the movable channel is set at least deep into the middle part of the connecting rod 132 along the length direction of the connecting rod 132, and the peripheral side of the connecting rod 132 is provided with a clamping groove connected to the movable channel, and the adjustment block 134 is configured as a toggle piece that is slidably adapted to the clamping groove, and the adjustment block 134 is slid along the clamping groove to realize the movable connection between the adjustment block 134 and the connecting rod 132. By adjusting the position of the adjusting block 134, the distance between the adjusting block 134 and the eccentric wheel 131 is adjusted, and the position adjustment of the adjusting block 134 is completed by tightening the adjusting block 134, so that when the eccentric wheel 131 is switched to the locking position, the eccentric wheel 131 abuts against the groove wall of the mounting groove 121, so that the groove wall of the mounting groove 121 abuts against the second connecting part 113, and further limits the sliding of the connecting part 110 and the mounting groove 121, thereby optimizing the locking effect.

[0061] Reference Figure 3 As another embodiment of the present application, the locking member 130 includes only an eccentric wheel 131. The locking member 130 is provided with a mounting seat 136 near the mounting groove 121. The eccentric wheel 131 is rotatably mounted on the mounting seat 136. In this embodiment, whether the connecting portion 110 is provided with the connecting guide groove 1131, the avoidance groove, the connecting channel, etc. is not limited.

[0062] In the aforementioned embodiment of the present application, the eccentric wheel 131 has a long axis section 1311. It can be understood that the eccentric wheel 131 has two axial lengths, the short axis and the long axis. Corresponding to the long axis position, the axis section on the eccentric wheel 131 that is longer and has a larger range of change in the end face during the rotation process relative to the short axis is determined as the long axis section 1311. The long axis section 1311 of the eccentric wheel 131 is arranged close to the groove wall of the installation groove 121. Specifically, the long axis section 1311 of the eccentric wheel 131 is arranged close to the groove wall of the installation groove 121. Figure 9 The eccentric wheel 131 is provided with a handle 133. When it is necessary to adjust the position of the connecting portion 110 on the transport device or to adjust the distance between the limiting plate 111 and the transport device 200, the eccentric wheel 131 is rotated by turning the handle 133 outward away from the groove wall of the installation groove 121 to switch the eccentric wheel 131 to an unlocked position. In the unlocked position, the long axis section 1311 of the eccentric wheel 131 is away from the installation portion 120, so as to release the pressure on the groove wall of the installation groove 121 and release the sliding restriction of the connecting portion 110 and the installation groove 121, so that the connecting portion 110 can move relative to the installation groove 121. Figure 8 After the position adjustment is completed, the eccentric wheel 131 is rotated by turning the handle 133 inward toward the mounting groove 121 to switch the eccentric wheel 131 to the locking position. In the locking position, the long axis section 1311 of the eccentric wheel 131 is close to the mounting portion 120, and the eccentric wheel 131 presses against the groove wall of the mounting groove 121. Alternatively, when a pressure block 135 or other structure is provided between the eccentric wheel 131 and the mounting portion 120, the eccentric wheel 131 presses against the groove wall of the mounting groove 121 through the pressure block 135 or other structure. In this way, it can be used to limit the sliding of the connecting portion 110 and the mounting groove 121, preventing the connecting portion 110 from moving relative to the mounting groove 121. The overall structure is simple, the locking member 130 is compact, and it is easy to operate, convenient for production use and daily maintenance.

[0063] In some expandable embodiments of the present application, in order to achieve locking and further optimize safety, and avoid safety hazards caused by the connection part 110 sliding relative to the transportation device 200 when loading or transporting the objects to be transported, a locking position or other locking structure can be provided on the mounting plate, the connection part 110 or other structures; the specific setting can be based on actual conditions and is not limited here.

[0064] To simplify the structure, refer to Figure 4 In one embodiment, the connecting portion 110 includes a first connecting portion 112 and a second connecting portion 113 connected as one body, the first connecting portion 112 and the second connecting portion 113 are arranged at an angle, and the second connecting portion 113 is slidably arranged in the mounting groove 121.

[0065] The limiting plate 111 is arranged on the first connecting part 112, and the second connecting part 113 is slidably arranged on the installation groove 121, so as to slide the second connecting part 113 along the installation groove 121 while driving the limiting plate 111 arranged on the first connecting part 112 to move, so as to flexibly adjust the distance between the limiting plate 111 of the limiting assembly 100 and the transportation device 200, and further realize the limitation of objects to be transported of different sizes.

[0066] Optionally, the first and second connecting portions 112, 113 may be configured as rods, plates, or any other suitable structure suitable for practical use, and may intersect with each other. The first and second connecting portions 112, 113 may be made of a material with a certain degree of bendability to enhance structural strength, increase resistance to bending stress, and improve overall structural stability. This allows for positioning of transported objects of varying sizes, prevents bending deformation when subjected to external forces, and effectively extends service life.

[0067] To facilitate mass production and use, improve versatility, and achieve position limiting for different types of objects to be transported, in one embodiment, the first connecting portion 112 and the second connecting portion 113 are arranged perpendicular to each other.

[0068] Optionally, when the first connection part 112 and the second connection part 113 both adopt a rod-shaped structure, the first connection part 112 and the second connection part 113 can be optionally connected to form an L-shape, a T-shape or any other structure suitable for actual use; when at least one of the first connection part 112 and the second connection part 113 is provided with multiple connection segments and the overall shape is L-shaped, etc., the first connection part 112 and the second connection part 113 can be optionally connected to form an H-shape, a U-shape or any other structure suitable for actual use; the specific setting can be based on actual conditions and is not limited here.

[0069] This application primarily describes an example in which both the first connecting portion 112 and the second connecting portion 113 utilize a straight rod structure, are disposed perpendicularly to each other, and are connected to form an L-shape. In the embodiment of this application, the limiting plate 111 is disposed on the side of the first connecting portion 112 that is closest to the object to be transported. The shape, length, and structure of the first and second connecting portions 112, 113, as well as the connection angle between them, can be modified as needed, without limitation herein.

[0070] In some other optional embodiments of the present application, the first connecting portion 112 can also be configured as a liftable and foldable structure to be suitable for objects to be transported of different thicknesses or different stacking heights, so as to further expand the scope of application and be suitable for transporting objects to be transported of various types and sizes; the specific settings can be made according to actual conditions and are not limited here.

[0071] To simplify the overall structure and facilitate assembly. Figure 4 In one embodiment, the second connecting portion 113 is provided with a connecting guide groove 1131 along its length, and the groove walls on both sides of the mounting groove 121 are respectively provided with a first connecting hole 1221 and a second connecting hole 1222. A connecting rod 132 is provided through the first connecting hole 1221, the connecting guide groove 1131, and the second connecting hole 1222.

[0072] Alternatively, the connecting guide slot 1131 may be a long, waist-shaped slot, serving as a guide for the movement of the connecting rod 132 during position adjustment. The first end of the connecting rod 132 at least partially extends out of the first connecting hole 1221, and the adjustment block 134 is disposed at the first end of the connecting rod 132. The second end of the connecting rod 132 at least partially extends out of the second connecting hole 1222, and the eccentric wheel 131 is rotatably connected to the second end of the connecting rod 132.

[0073] To reduce assembly steps for the position-limiting assembly and allow for immediate use when limiting the position of an object to be transported, the mounting portion 120, connecting portion 110, and locking member 130 can be pre-assembled to form a pre-assembled structure. When used in a transport device 200, the pre-assembled structure can be mounted on the transport assembly 220 of the transport device using the mounting position provided on the mounting portion 120 for immediate use.

[0074] In one embodiment, the second connecting portion 113 is provided with scale marks 1132 along its length.

[0075] Scale marks 1132 are optionally provided along the connecting guide groove 1131. The scale marks 1132 can be used to provide a precise measurement reference, and are used to indicate the relative position of the second connecting portion 113 and the mounting portion 120 during position adjustment. Specifically, when the size of the object to be transported is known in advance, the installation position of the second connecting portion 113 and the mounting portion 120 can be pre-adjusted by using the scale marks 1132 provided on the second connecting portion 113, so as to further adjust the limiting area 210 formed by the multiple limiting components of the transport device. When the size of the object to be transported is unknown, after the limiting area 210 for fixing the object to be transported is enclosed and formed, the size of the object to be transported can also be directly obtained by reading the scale marks 1132, so as to achieve circumferential limiting of the object to be transported and simultaneously achieve measurement of the size of the object to be transported, which is convenient for use.

[0076] Reference Figure 2 、 Figure 6 、 Figure 8 、 Figure 9 In one embodiment, the locking member 130 further includes a pressing block 135 , which is disposed between the eccentric wheel 131 and the mounting portion 120 .

[0077] Specifically, the mounting portion 120 includes a first side plate 1231 and a second side plate 1232 that are arranged opposite to each other, the mounting groove 121 is formed between the first side plate 1231 and the second side plate 1232, the first connecting hole 1221 is provided in the first side plate 1231, the second connecting hole 1222 is provided in the second side plate 1232, and the pressure block 135 is provided between the eccentric wheel 131 and the second side plate 1232. Optionally, when the locking member 130 only includes the eccentric wheel 131, the pressure block 135 is arranged between the peripheral side of the eccentric wheel 131 and the second side plate 1232, and the pressure block 135 can be specifically fixed on the second side plate 1232 or movably arranged between the eccentric wheel 131 and the second side plate 1232; when the locking member 130 also includes a connecting rod 132 and an adjusting block 134, the pressure block 135 is arranged between the peripheral side of the eccentric wheel 131 and the second side plate 1232, and the connecting rod 132 is arranged through the pressure block 135.

[0078] Taking the locking member 130 including the eccentric wheel 131, the connecting rod 132 and the adjusting block 134 as an example, the pressure block 135 and the connecting rod 132 are connected by a movable pair, and the movable pair allows the pressure block 135 and the connecting rod 132 to move linearly along a fixed direction, that is, allowing the pressure block 135 to move closer to or away from the adjusting block 134. By adjusting the distance between the pressure block 135 and the adjusting block 134, the tightness of the eccentric wheel 131 and the side panel is controlled to further adjust the gap between the first side panel 1231, the second side panel 1232 and the second connecting portion 113. In the locked position, the long axis section 1311 of the eccentric wheel 131 is close to the second side plate 1232, and the pressing block 135 provided between the eccentric wheel 131 and the mounting portion 120 presses against the second side plate 1232, thereby limiting the sliding of the connecting portion 110 and the mounting groove 121, confining the connecting portion 110 in the mounting groove 121, and preventing the connecting portion 110 from moving relative to the mounting groove 121. The provision of the pressing block 135 also serves as a buffer, and ensures that in the locked state, the pressing block 135 can stably press against the second side plate 1232, so that the first side plate 1231 and the second side plate 1232 are relatively close.

[0079] Reference Figure 5 In one embodiment, the mounting groove 121 is formed between the first side plate 1231 and the second side plate 1232 , and the first side plate 1231 and the second side plate 1232 are used to constitute the groove walls on both sides of the mounting groove 121 .

[0080] It is understandable that the first side plate 1231 and the second side plate 1232 are spaced apart from each other. At least one of the first side plate 1231 and the second side plate 1232 can be moved closer to or away from the other by deformation, displacement, or the like.

[0081] To simplify the overall structure, facilitate operation, and improve the limiting efficiency, specifically, the second side plate 1232 is an elastic plate, and the first side plate 1231 can be optionally configured as an elastic plate or other plate member to achieve unilateral or bilateral adjustment. When the eccentric wheel 131 is switched to the locked position, the second side plate 1232 is pressed by the eccentric wheel 131, moving closer to the first side plate 1231 and abutting the second connecting portion 113, thereby further limiting the sliding of the second connecting portion 113 and the mounting groove 121; when the eccentric wheel 131 is switched to the unlocked position, the eccentric wheel 131 releases the pressure on the second side plate 1232, and the second side plate 1232 elastically resets and moves away from the first side plate 1231 and separates from the second connecting portion 113, thereby further releasing the sliding restriction on the second connecting portion 113.

[0082] Furthermore, to achieve bilateral adjustment and further optimize the locking effect, the first side plate 1231 is also configured as an elastic plate, and the adjustment block 134 is movably connected to the connecting rod 132. The adjustment block 134 is configured to move closer to the eccentric wheel 131 and abut against the first side plate 1231, or to move away from the eccentric wheel 131 and separate from the first side plate 1231. The distance between the first side plate 1231 and the second side plate 1232 is adjusted by at least one of the eccentric wheel 131 and the adjustment block 134 to restrict or release the sliding restriction between the connecting portion 110 and the mounting slot 121.

[0083] In one embodiment, a mounting position is defined on the mounting portion 120 , and the mounting portion 120 is detachably fixed to the transport device 200 via the mounting position.

[0084] Optionally, the mounting portion 120 is provided with one or more mounting locations, each of which can be connected to the transport device via screws or other means. The multiple mounting locations include a first mounting location 1241. The mounting portion 120 includes two first mounting plates 1251, each of which is provided with a first mounting location 1241. The two first mounting plates 1251 are located on either side of the mounting slot 121 and are removably secured to the transport device 200 via the first mounting locations 1241. Optionally, the first mounting plates 1251 are parallel to the plane of the second connecting portion 113, and the mounting portion 120 is removably mounted to the base 221 of the transport device 200 via the first mounting locations 1241.

[0085] Furthermore, the plurality of mounting positions include a second mounting position 1242. The mounting portion 120 includes a second mounting plate 1252. The second mounting plate 1252 is provided with one, two, or more second mounting positions 1242. The second mounting plate 1252 is parallel to the limiting plate 111. The second mounting position 1242 is configured to be mounted on the side edge 2211 of the base 221 of the transport device 200 or other side structure of the transport device 200. The plurality of mounting positions include a third mounting position 1243. The mounting portion 120 includes a third mounting plate 1253. The third mounting plate 1253 is in an inverted U-shape. The third mounting positions 1243 are provided on both sides of the third mounting portion 120. The two third mounting positions 1243 provided on both sides of the third mounting portion 120 are arranged opposite the second connecting portion 113. The third mounting position 1243 is configured to be removably mounted on a connecting member or other crossbeam structure of the transport device 200 that is parallel to the second connecting portion 113.

[0086] Optionally, the mounting portion 120 further includes a connecting plate 126. The connecting plate 126 is positioned corresponding to the mounting slot 121 and connected between the first side plate 1231 and the second side plate 1232 to restrain the second connecting portion 113 within the mounting slot 121, thereby preventing the connecting portion 110 from shifting during position adjustment. The specific configuration of the mounting slot 121 may vary depending on the actual structure and is not limited herein.

[0087] Reference Figure 10 、 Figure 11 The transport device 200 proposed in this application includes a transport assembly 220 and multiple position-limiting assemblies. The transport assembly 220 is used to carry and transfer objects to be transported. At least one of the multiple position-limiting assemblies of the transport device 200 utilizes the position-limiting assembly 100 described in the above embodiment. The multiple position-limiting assemblies of the transport device 200 are distributed along the circumference of the transport device 200 to enclose and form a position-limiting area 210 for securing the objects to be transported.

[0088] The specific structure of the limiting component 100 refers to the above embodiment. Since the transportation device 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0089] The transport assembly 220 includes a base 221 , on which rollers 240 are optionally provided to carry and transfer objects to be transported.

[0090] Taking the example of multiple limiting assemblies distributed circumferentially along the transport device 200, including at least two limiting assemblies 100 according to the aforementioned embodiments, in one embodiment, limiting regions 210 are provided on the transport device 200 at predetermined relative spacings, with the relative spacings being formed between the first connecting portions 112 of the multiple limiting assemblies 100. By adjusting the installation positions of the second connecting portions 113 and the mounting portions 120 of each limiting assembly 100, using the size of the transported object as the predetermined relative spacing, circumferential limiting of the transported object can be achieved.

[0091] In one embodiment, the object to be transported is a photovoltaic module 300 to be transported, and the relative spacing includes a first spacing and a second spacing. When the plurality of limiting assemblies include the four limiting assemblies of the aforementioned embodiment, specifically, the first limiting assembly 101, the second limiting assembly 102, the third limiting assembly 103, and the fourth limiting assembly 104, the first limiting assembly 101 and the second limiting assembly 102 are arranged relative to each other, and the first spacing is formed between the limiting plate 111 of the first limiting assembly 101 and the limiting plate 111 of the second limiting assembly 102, and corresponds to the maximum length of the photovoltaic module 300 to be transported; the third limiting assembly 103 and the fourth limiting assembly 104 are arranged relative to each other, and the second spacing is formed between the limiting plate 111 of the third limiting assembly 103 and the limiting plate 111 of the fourth limiting assembly 104, and corresponds to the maximum width of the photovoltaic module 300 to be transported. The length of the limiting plate 111 is not less than the stacked thickness of the photovoltaic modules 300 to be transported.

[0092] The size of the object to be transported is used as the preset relative spacing, with the length of the object to be transported corresponding to the first spacing and the width of the object to be transported corresponding to the second spacing. Specifically, according to different requirements of actual use, the enclosed limiting area can simultaneously limit multiple photovoltaic modules 300 of the same size or multiple photovoltaic modules 300 of different sizes. When used to simultaneously transport multiple photovoltaic modules 300 of different sizes, the length and width of the enclosed limiting area 210 are determined by the maximum length and maximum width of the photovoltaic modules 300 to be transported, respectively. The first connecting portion 112 is provided with a limiting plate 111. The length dimension of the limiting plate 111 refers to the dimension of the limiting plate 111 set along the length direction of the first connecting portion 112. The length of the limiting plate 111 is determined according to the stacking thickness of the photovoltaic modules 300 to be transported, so as to achieve stable transportation of photovoltaic modules 300 of different quantities and stacking thicknesses to be transported.

[0093] In one embodiment, the transport assembly 220 includes a base 221 having a plurality of side edges 2211 . Optionally, each side edge 2211 is provided with one or more limiting assemblies.

[0094] Specifically in the embodiment of the present application, a plurality of limiting assemblies 100 are disposed one-to-one on a plurality of side edges 2211. The limiting plates 111 of the plurality of limiting assemblies 100 distributed circumferentially along the base 221 enclose a limiting area 210 for fixing the object to be transported.

[0095] Furthermore, the transport device 200 includes a plurality of support assemblies 230, each of which is disposed one-to-one on the plurality of side edges 2211 to support the transported photovoltaic modules 300. Optionally, the support assemblies 230 are detachably mounted on the side edges 2211 of the base 221, allowing the transport height of the photovoltaic modules 300 to be adjusted by using support assemblies 230 of different heights.

[0096] Taking the photovoltaic module 300 as the object to be transported, and the multiple limiting assemblies distributed along the circumference of the transport device 200 including at least two limiting assemblies 100 of the aforementioned embodiment as an example, the specific implementation process of the transport device 200 of the present application is as follows:

[0097] According to the requirements of the use environment of the transportation device 200, limiting components are respectively set on the four side edges 2211 of the base 221 of the transportation component 220, wherein at least one of the limiting components on the left and right sides is the aforementioned limiting component 100, and at least one of the limiting components on the front and rear sides is the aforementioned limiting component 100, and the four limiting components are connected and fixed to the corresponding side edges 2211 by screw connection or the like.

[0098] During installation, the limiting assembly is pre-installed on the transport device 200. After placing the first photovoltaic module 300 on the transport device 200, the eccentric wheel 131 of one of the limiting assemblies 100 is opened according to the actual length and width of the photovoltaic module 300. The second connecting portion 113 is slid so that the buffer pad of the limiting plate 111 of the corresponding limiting assembly 100 abuts the edge of the photovoltaic module 300. The connecting portion 110 of the limiting assembly 100 is then locked to the transport device 200 by locking the eccentric wheel 131. This process is repeated until all limiting assemblies 100 are installed and adjusted, so that the circumferential position of the photovoltaic module 300 is achieved through the limiting area 210 enclosed by multiple limiting assemblies.

[0099] When multiple photovoltaic modules 300 of the same size need to be transported simultaneously, the remaining photovoltaic modules 300 are stacked and placed within the enclosed limiting area 210. By placing the photovoltaic modules 300 within the limiting area 210 formed by the multiple limiting assemblies 100, the limiting area 210 provides protection for the photovoltaic modules 300. The limiting plates 111 provide anti-slip protection around the photovoltaic modules 300, ensuring safe transportation of the photovoltaic modules 300. After adjustment is completed, subsequent transport of photovoltaic modules 300 of the same size does not require further adjustment, ensuring ease of use.

[0100] The above description is merely an exemplary embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structural transformation made using the contents of the present application specification and drawings under the technical concept of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
