[0019] This utility model provides a trolley for photovoltaic installation equipment, comprising multiple trolley modules arranged at intervals along the length of the photovoltaic module. Each trolley module is movably installed on the main trolley within the photovoltaic installation equipment and connected to a lifting device. Since photovoltaic modules are typically large, designing the trolley as multiple modular units, spaced at intervals along the length of the photovoltaic module, effectively reduces the amount of material used in the trolley while ensuring balanced lifting of the photovoltaic module. This reduces the trolley's weight and volume, improving its lightweight design and making it more compact.

[0020] In addition, multiple trolley modules can be independently connected to the main vehicle and the spreader, which helps to improve the flexibility of spreadinger movement and, in turn, is expected to improve the flexibility of photovoltaic module attitude adjustment during photovoltaic module installation.

[0030] To make the above-mentioned objectives, features and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] In related technologies, photovoltaic installation equipment may include a main vehicle, a trolley, and a lifting device. The trolley is connected to the main vehicle, and the lifting device is connected to the trolley. The lifting device is used to lift the photovoltaic modules. In practical applications, the main vehicle travels to the area where the photovoltaic modules need to be installed, the lifting device lifts the photovoltaic modules to be installed and moves them to the installation position. During the installation process, the position can be fine-tuned using the trolley module according to actual needs. It is understandable that the lifting device can also first lift the photovoltaic modules to be installed, and then the main vehicle travels to the area where the photovoltaic modules need to be installed.

[0032] The photovoltaic module includes two types: one where the photovoltaic module consists of a single photovoltaic module, and the other where the photovoltaic module consists of multiple photovoltaic modules. This application applies not only to the case where the photovoltaic module consists of a single photovoltaic module, but also to the case where the photovoltaic module consists of multiple photovoltaic modules, and is particularly helpful in improving the lightweight design of photovoltaic installation equipment.

[0033] When a photovoltaic module comprises multiple photovoltaic modules, these modules can be arranged in a certain form and fixed together by a fixing structure. For example, a photovoltaic module may consist of 26 photovoltaic modules, typically arranged in two rows and connected as a whole by support beams, purlins, and other structures to form a photovoltaic module (also known as a photovoltaic array semi-finished product), with an overall length reaching tens of meters. During photovoltaic module installation, the lifting device uses suction cups to adsorb the photovoltaic modules. To ensure reliable adsorption, each photovoltaic module is usually equipped with a corresponding suction cup, thus the entire lifting device also reaches a length of tens of meters. Existing trolleys are of a one-piece structure, and their corresponding overall structure is also very long in order to stably lift the photovoltaic modules, resulting in a large overall weight of the photovoltaic installation equipment. Based on this problem, this application provides a split-type trolley for photovoltaic installation equipment.

[0034] The following is combined Figure 1 and Figure 5 This application describes the specific structure of the trolley used for photovoltaic installation equipment. The photovoltaic installation equipment 100 includes a trolley 1, a main trolley 2, and a lifting device 3 for hoisting photovoltaic modules. The trolley 1 includes multiple trolley modules 10, each trolley module 10 being movably mounted on the main trolley 2, and each trolley module 10 being connected to the lifting device 3. The multiple trolley modules 10 are arranged at intervals along the length of the photovoltaic modules.

[0035] As can be seen from the above, photovoltaic modules are usually quite large. By designing the trolley 1 as a split unit into multiple trolley modules 10 and arranging them at intervals along the length of the photovoltaic module, compared with the integrated trolley design, the trolley 1 of this application can effectively reduce the amount of material used in the trolley 1 while ensuring the balance of the photovoltaic module hoisting, thereby reducing the weight and volume of the trolley 1, improving the lightweighting of the trolley 1, and making the trolley 1 lighter.

[0036] In some embodiments, the trolley 1 includes two trolley modules 10. The spreader 3 is connected through the two trolley modules 10. Each trolley module 10 serves as a connection point, enabling the spreader 3 to be connected at two connection points. This ensures the stability of the spreader 3 while minimizing the weight and volume of the trolley 1.

[0037] The specific positions of the two trolley modules 10 arranged at intervals along the length of the photovoltaic module can be determined based on the dimensions of the photovoltaic module along its length. In some non-limiting embodiments, the photovoltaic module is divided into three equal parts at the center points of the two trolley modules 10 along its length. This also roughly divides the lifting device 3 into three equal parts, ensuring balanced force distribution on the lifting device 3. This ensures stability during photovoltaic module installation and reduces the probability of the lifting device 3 breaking due to concentrated force in a certain area. Of course, in other embodiments, the photovoltaic module may not be divided into three equal parts at the center points of the two trolley modules 10, as long as the two trolley modules 10 are symmetrical about the center of the photovoltaic module.

[0038] It should be noted that, in practice, depending on factors such as the size of the photovoltaic module, the tolerance for hoisting stability, and the structural type of the main vehicle 2, the number of vehicle modules 10 included in the vehicle 1 can also be three or more.

[0039] In some embodiments, multiple vehicle modules 10 in vehicle 1 can move synchronously relative to the main vehicle 2 to achieve translation of the photovoltaic module in a set direction.

[0040] In other embodiments, along the length of the photovoltaic module, multiple trolley modules 10 are divided into two parts, with one part of the trolley modules 10 and the other part of the trolley modules 10 moving asynchronously relative to the main vehicle 2. This allows for the rotation of the photovoltaic module during installation, improving the flexibility of the photovoltaic module's attitude adjustment and adapting to different installation angle requirements.

[0041] To facilitate a better understanding of the technical solutions of this application by those skilled in the art, the accompanying drawings provided in this application illustrate the use of a vehicle 1 comprising two vehicle modules 10 as an example for detailed description. When the vehicle 1 comprises three or more vehicle modules 10, the corresponding number of vehicle modules 10 can be added based on the embodiments given below, which will not be elaborated here.

[0042] In some embodiments, refer to Figures 2-4 , Figure 6 as well as Figure 7 The trolley module 10 includes: a frame 11, a first micro-motion mechanism 12, and a second micro-motion mechanism 13. The frame 11 is movably mounted on the main vehicle 2.

[0043] The first micro-motion mechanism 12 includes a first micro-motion frame 121 and a first drive mechanism 122. The first micro-motion frame 121 is movably mounted on the vehicle frame 11, and the first drive mechanism 122 is used to drive the first micro-motion frame 121 to move relative to the vehicle frame 11 in a first direction x.

[0044] The second micro-motion mechanism 13 includes a second micro-motion frame 131 and a second drive mechanism. The second micro-motion frame 131 is movably mounted on the first micro-motion frame 121, and the second drive mechanism drives the second micro-motion frame 131 to move relative to the first micro-motion frame 121 in a second direction y. The second micro-motion frame 131 is used to connect the lifting device 3.

[0045] The first direction x intersects the second direction y. For example, the first direction x and the second direction y are perpendicular. It is understood that the angle between the first direction x and the second direction y can also be acute or obtuse. In the following embodiments, the perpendicularity of the first direction x and the second direction y is used as an example for specific illustration.

[0046] Furthermore, one of the first direction x and the second direction y is the travel direction of the main vehicle 2, and the other is the movement direction of the frame 11 relative to the main vehicle 2; the length direction of the photovoltaic module is parallel to the travel direction of the main vehicle 2, and the width direction of the photovoltaic module is parallel to the movement direction of the frame 11 relative to the main vehicle 2. It should be noted that... Figures 1-4 The diagram is illustrated by taking the first direction x as the direction of movement of the frame 11 relative to the main vehicle 2, and the second direction y as the direction of travel of the main vehicle 2. Figures 5-7 The diagram illustrates the movement of the main vehicle 2 in the first direction x and the movement of the frame 11 relative to the main vehicle 2 in the second direction y. It should be noted that the specific settings of the first direction x and the second direction y are not limited to those shown in the diagram and can be adjusted according to actual needs.

[0047] Since the second micro-motion frame 131 is movably mounted on the first micro-motion frame 121, when the first drive mechanism 122 drives the first micro-motion frame 121 to move relative to the frame 11 along the first direction x, the second micro-motion frame 131 can drive the connected lifting device 3 to move along the first direction x. The photovoltaic module suspended by the lifting device 3 also moves along the first direction x with the lifting device 3, realizing the adjustment of the position of the photovoltaic module in the first direction x. When the second drive mechanism drives the second micro-motion frame 131 to move relative to the first micro-motion frame 121 along the second direction y, the second micro-motion frame 131 drives the connected lifting device 3 to move along the second direction y. The photovoltaic module suspended by the lifting device 3 also moves along the second direction y with the lifting device 3, realizing the adjustment of the position of the photovoltaic module in the second direction y. When the first drive mechanism 122 drives the first micro-motion frame 121 to move relative to the frame 11 along the first direction x, and the second drive mechanism drives the second micro-motion frame 131 to move relative to the first micro-motion frame 121 along the second direction y, the second micro-motion frame 131 can drive the connected lifting device 3 to move along both the first direction x and the second direction y, thereby simultaneously adjusting the position of the photovoltaic module in both directions x and y. In this way, the first micro-motion mechanism 12 can fine-tune the position of the photovoltaic module in the first direction x, and the second micro-motion mechanism 13 can fine-tune the position of the photovoltaic module in the second direction y. Based on the position adjustment requirements in the actual installation scenario of the photovoltaic module, the position of the photovoltaic module can be finely adjusted in the first direction x by the first micro-motion mechanism 12 alone; or the position of the photovoltaic module can be finely adjusted in the second direction y by the second micro-motion mechanism 13 alone; or the position of the photovoltaic module can be finely adjusted in the first direction x by the first micro-motion mechanism 12 and in the second direction y by the second micro-motion mechanism 13 at the same time, so as to achieve the simultaneous fine adjustment of the position of the photovoltaic module in both the first direction x and the second direction y, so as to ensure the precise alignment of the photovoltaic module with the photovoltaic support device and ensure the precise installation of the photovoltaic module.

[0048] Reference Figures 1 to 7 In some embodiments, the frame 11 has at least a pair of first support portions 111 (i.e., two first support portions 111) extending along a first direction x for supporting the first micro-motion frame 121 and allowing the first micro-motion frame 121 to move relative to the first support portions 111 in the first direction x; and the two first support portions 111 are arranged at intervals along a second direction y, with the two first support portions 111 being spaced apart to allow for assembly space for the installation of other equipment such as the first micro-motion frame 121.

[0049] Furthermore, in some non-limiting embodiments, the frame 11 may also include a pair of support frames 112 (i.e., two support frames 112) extending along the second direction y. The two ends of the two first load-bearing parts 111 are respectively connected by the two support frames 112, and together they form a rectangular frame structure. The rectangular frame structure of the frame 11 can simplify the structure, reduce the amount of material used, and provide relatively more and more flexible assembly space while meeting the load-bearing requirements of the first micro-motion mechanism 12. This helps to further simplify the overall structure of the vehicle module 10, making the overall structure of the vehicle module 10 more compact and lightweight.

[0050] Furthermore, in some non-limiting embodiments, the frame 11 may also include a suspension beam 113 for movably connecting to the main vehicle 2. The number of suspension beams 113 may be one, two, or another number. For example... Figure 2 and Figure 6 As shown, two suspension beams 113 are arranged at intervals along the second direction y. With multiple suspension beams 113, the frame 11 can be more stably connected to the main vehicle 2.

[0051] The suspension beam 113 is suspended above the frame 11. This avoids interfering with other components mounted on the frame 11 (e.g., the first micro-motion mechanism 12 and the second micro-motion mechanism 13).

[0052] In some embodiments, the cantilever beam 113 is connected to a pair of support frames 112. The cantilever beam 113 includes a pair of uprights 1131 (i.e., two uprights 1131) and a crossbeam 1132. The pair of uprights 1131 extend vertically, and their bottom ends are connected to the support frames 112. The two ends of the crossbeam 1132 are respectively connected to the top ends of the two uprights 1131, so as to be erected above the pair of support frames 112. The crossbeam 1132 can be straight or bent. Figure 2 The diagram illustrates a bent crossbeam 1132 as an example. A mounting part 1133 is provided on the crossbeam 1132, which is used to connect to the main vehicle 2. The mounting part 1133 is integrated with the crossbeam 1132, or the mounting part 1133 is detachably connected to the crossbeam 1132.

[0053] Furthermore, the frame 11 may also include a reinforcing rib 114. The reinforcing rib 114 is connected to the suspension beam 113 and the support frame 112. For example, the reinforcing rib 114 is connected to the column 1131 and the support frame 112.

[0054] The frame 11 described above has a simple and compact structure, reducing weight while ensuring stable load-bearing function. Of course, the specific structure of the frame 11 in other modified embodiments is not limited to the above description and can be adjusted according to specific circumstances. For example, the support frame 112 can be omitted, and the two suspension beams 113 can be connected to the two first load-bearing parts 11 respectively, and the two suspension beams 113 can be connected by connecting parts to form a whole. For another example, the frame 11 may not be a rectangular frame structure, but may be other polygonal frame structures, etc.

[0055] Refer to Figures 1 to 7 In some embodiments, the first micro-motion frame 121 has at least a pair of first support portions 1211 (i.e., two first support portions 1211) extending along a first direction x. The pair of first support portions 1211 are adapted to a pair of first bearing portions 111 and move relative to the pair of first bearing portions 111 along the first direction x.

[0056] Among them, a pair of first support parts 1211 are arranged at intervals along the second direction y. The pair of first support parts 1211 have a certain interval in the second direction y to provide corresponding assembly space for the assembly of other components (such as the first drive mechanism 122, the second micro-motion mechanism 13, etc.).

[0057] In this configuration, a pair of first support portions 1211 are respectively supported on a pair of first bearing portions 111. In the first direction x, the length of the first support portion 1211 is less than the length of the first bearing portion 111, so that the first support portion 1211 can move relative to the first bearing portion 111.

[0058] In some embodiments, the first support portion 1211 may be a plate-like structure to facilitate the installation of equipment such as the first drive mechanism 122. The first support portion 1211 may also be other suitable structural forms, which are not limited here. Furthermore, in some embodiments, the first micro-motion frame 121 further includes at least one second bearing portion 1212, which is used to connect the two first support portions 1211 and also to support the second micro-motion frame 131.

[0059] In some embodiments, the first micro-motion frame 121 and the vehicle frame 11 achieve relative movement via a first drive mechanism 122. Specifically, the first drive mechanism 122 includes at least one first drive module 1221. In some non-limiting embodiments, such as Figures 1 to 7 As shown, the first drive mechanism 122 includes two first drive modules 1221 to improve the smoothness of the movement of the first micro-motion frame 121 relative to the frame 11.

[0060] Furthermore, the first drive module 1221 includes a first power mechanism 12211, a first gear 12212, and a first rack 12213. Since the first drive module 1221 drives the first gear 12212 to rotate relative to the first rack 12213 via the first power mechanism 12211, the first power mechanism 12211 and the first gear 12212 are typically located in the same position. This allows for a larger transmission ratio within a smaller space, resulting in a smaller size for the first drive module 1221 and contributing to a more compact and miniaturized overall structure of the vehicle 1. Furthermore, the gear and rack transmission method ensures a constant transmission ratio, making power transmission stable and reliable, and providing high-precision output speed and torque. This helps improve the accuracy and efficiency of the first micro-motion mechanism 12 in fine-tuning the position of the photovoltaic module in the first direction x.

[0061] A first power mechanism 12211 is installed on one of the first bearing portion 111 and the first support portion 1211. A first gear 12212 is installed on one of the corresponding first bearing portion 111 and the first support portion 1211, and the first gear 12212 is connected to the first power mechanism 12211 and rotates under the drive of the first power mechanism 12211. A first rack 12213 is installed on the other of the corresponding first bearing portion 111 and the first support portion 1211, and the first rack 12213 meshes with the first gear 12212.

[0062] For example, the first power mechanism 12211 is installed on the first bearing part 111, the first gear 12212 is installed on the first bearing part 111, and the first rack 12213 is installed on the first support part 1211.

[0063] For example, the first power mechanism 12211 is installed on the first support part 1211. The first gear 12212 is installed on the first support part 1211, and the first rack 12213 is installed on the first bearing part 111.

[0064] In some embodiments, when the first drive mechanism 122 includes two first drive modules 1221, taking the first power mechanism 12211 disposed on the first support portion 1211 as an example, each first support portion 1211 is provided with a first power mechanism 12211 and a first gear 12212.

[0065] It should be noted that the first drive module 1221 can also adopt other power transmission structures.

[0066] For example, the first drive module 1221 may include a first power mechanism 12211, a drive sprocket, a driven sprocket, and a chain. The chain is wound around the drive sprocket and the driven sprocket. The first power mechanism 12211, the drive sprocket, and the driven sprocket may be disposed on the first support portion 1211. The first power mechanism 12211 drives the drive sprocket to rotate, and the teeth of the drive sprocket mesh with the chain links, causing the driven sprocket to rotate, so that the first support portion 1211 moves relative to the first bearing portion 111, and then the first support portion 1211 drives the first micro-motion frame 121 to move relative to the frame 11. Using chain drive for power transmission provides accurate transmission ratios, low cost, and adaptability to harsh environments such as high temperatures and dust.

[0067] For example, the first drive module 1221 may include a first power mechanism 12211, a drive wheel, a driven wheel, and an annular belt. The annular belt is fitted onto the drive wheel and the driven wheel, forming a closed loop. The first power mechanism 12211, the drive wheel, and the driven wheel may be disposed on the first support portion 1211. The first power mechanism 12211 drives the drive wheel to rotate. When the drive wheel rotates, it drives the belt to move through friction, and the belt then drives the driven wheel to rotate, thereby realizing the movement of the first micro-motion frame 121 relative to the frame 11, thus achieving power transmission. Since the belt's elasticity can absorb vibration and impact, using belt drive can make the movement of the first micro-motion frame 121 relative to the frame 11 more stable.

[0068] For example, the first drive module 1221 may include a first power mechanism 12211, a worm gear, and a worm. The worm may be disposed on the first bearing part 111, and the first power mechanism 12211 and the worm gear may be mounted on the first support part 1211. The first power mechanism 12211 drives the worm gear to rotate, and the worm gear meshes with the worm to move relative to the worm, thereby driving the first micro-motion frame 121 to move relative to the frame 11.

[0069] In specific implementation, the first power mechanism 12211 can be a motor, or a three-in-one motor and reducer that integrates a motor, reducer and encoder, or other mechanisms with driving functions.

[0070] In a specific implementation, the first micro-motion mechanism 12 further includes a first guide mechanism 123. The first guide mechanism 123 is disposed on one of the frame 11 and the first micro-motion frame 121, and is used to guide the first micro-motion frame 121 to move relative to the frame 11 along a first direction x.

[0071] For example, the first guide mechanism 123 is disposed on the first bearing portion 111. Or, for example, the first guide mechanism 123 is disposed on the first support portion 1211.

[0072] In some embodiments, such as Figures 2-4As shown, the first guide mechanism 123 includes at least one first guide wheel. The at least one first guide wheel is rotatably connected to one of the frame 11 and the first micro-motion frame 121. The figure illustrates an example of two first guide wheels rotatably connected to the first micro-motion frame 121. It is understood that the number of first guide wheels is not limited to two, and can be any other suitable number.

[0073] In other embodiments, the first guide mechanism 123 includes a first slide rail and a first slider adapted to the first slide rail. The first slide rail is disposed on one of the frame 11 and the first micro-motion frame 121, and the first slider is disposed on the other of the frame 11 and the first micro-motion frame 121. To further reduce material usage, part or all of the frame 11 and the first micro-motion frame 121 may be reused as the first slide rail.

[0074] In some embodiments, the upper end of the second micro-motion frame 131 is connected to the first micro-motion frame 121, and the lower end of the second micro-motion frame 131 is provided with two lifting parts 133 for connecting the lifting device 3. The two lifting parts 133 are arranged at intervals along the width direction of the photovoltaic module. During photovoltaic module installation, the relative distance between the two ends of the photovoltaic module and the ground along the width direction can be flexibly adjusted by using the two lifting parts 133 arranged at intervals along the width direction of the photovoltaic module, thereby realizing the flipping of the photovoltaic module to meet the requirements of tilting installation of the photovoltaic module.

[0075] In some non-limiting embodiments, the upper end of the second micro-motion frame 131 is movably connected to the first micro-motion frame 121. For example, the second micro-motion frame 131 is provided with a suspension part 1312, which is hung on the first micro-motion frame 121. The suspension part 1312 can be a shaft or a protrusion. When the suspension part 1312 is a protrusion, the first micro-motion frame 121 is provided with a sliding groove that matches the protrusion.

[0076] In some embodiments, the first micro-motion frame 121 has at least one second support portion 1212 extending along the second direction y. The second micro-motion frame 131 includes two opposing second support portions 1311, which are movably positioned on the second support portion 1212.

[0077] In practice, the second support part 1311 can be plate-shaped.

[0078] In some embodiments, the second support portion 1212 is parallel to a pair of support frames 112.

[0079] In some embodiments, the suspension portion 1312 is located between the two second support portions 1311 and is connected to the two second support portions 1311 respectively.

[0080] Furthermore, the second support portion 1311 may be provided with a hollow portion 13111. This is to further reduce the weight of the second support portion 1311, and thus further reduce the weight of the trolley 1.

[0081] In specific implementations, the structural style of the first micro-motion frame 121 varies depending on the number of second support parts 1212 included in the first micro-motion frame 121. Examples of possible structural styles for the second micro-motion frame 121 are given below.

[0082] In some embodiments, the number of second support portions 1212 is two, that is, the first micro-motion frame 121 includes a pair of second support portions 1212. The first micro-motion frame 121 is a rectangular frame structure. Figures 1 to 4 As shown, the first micro-motion frame 121 has a pair of first support portions 1211 extending along a first direction x and a pair of second bearing portions 1212 extending along a second direction y. The pair of first support portions 1211 and the pair of second bearing portions 1212 are connected respectively and together form a rectangular frame structure.

[0083] When the first direction x is the direction of movement of the frame 11 relative to the main vehicle 2, the width direction of the photovoltaic module (which is the direction of movement of the frame 11 relative to the main vehicle 2, or the direction perpendicular to the direction of travel of the main vehicle 2) is also the first direction x. To ensure that the two lifting parts 133 are spaced apart along the width direction of the photovoltaic module, the first micro-motion frame 121 can be a rectangular frame structure. This facilitates the installation of a second micro-motion mechanism 13 on each of the pair of second bearing parts 1212. Each of the two second micro-motion mechanisms 13 provides a lifting part 133, and the two lifting parts 133 provide two lifting points in the width direction of the photovoltaic module. This helps to achieve the flipping of the photovoltaic module during installation.

[0084] In other embodiments, the number of second support parts is one, and the first micro-motion frame is an I-shaped structure, such as... Figures 5 to 7 As shown, the first micro-motion frame 121 has a pair of first support portions 1211 extending along a first direction x and a second bearing portion 1212 extending along a second direction y. Both ends of the second bearing portion 1212 are connected to the pair of first support portions 1211, forming an I-shaped structure. Furthermore, both ends of the second bearing portion 1212 are connected to the midpoint of the pair of first support portions 1211 in the first direction x.

[0085] When the first direction x is the direction of travel of the main vehicle, the width direction of the photovoltaic module is the second direction y, which is perpendicular to the first direction x. In order to ensure that the two lifting parts 133 are arranged at intervals along the width direction of the photovoltaic module, the first micro-motion frame 121 can be selected as an I-shaped structure. At this time, a second micro-motion mechanism 13 can be set on a second bearing part 1212, and both lifting parts 133 are set on a second micro-motion mechanism 13. This simplifies the structure of the vehicle module 10 and helps to achieve the flipping of the photovoltaic module during the installation process.

[0086] In specific implementation, the arrangement of the lifting part 133 varies depending on the configuration of the first direction x and the second direction y. Examples are given below.

[0087] In some embodiments, refer to Figures 5 to 7 The second direction y is parallel to the width direction of the photovoltaic module. A connecting part is connected between the two second support parts 1311. The two hanging parts 133 are located in the connecting part and are arranged at intervals along the width direction of the photovoltaic module.

[0088] The connecting part can be a pin, located between the two second support parts 1311 and connected to each of the two second support parts 1311. There can be two connecting parts. The connecting part can rotate relative to the second support parts 1311 or be fixedly connected to the two support parts 1311. The lifting part 133 can be a pulley. The pulley is sleeved on the pin.

[0089] In some embodiments, refer to Figures 1 to 4 In the second direction y, which is parallel to the length of the photovoltaic module, the upper ends of the two second support parts 1311 are movably suspended from the second bearing part 1212, and the lower ends are respectively provided with lifting parts 133. At this time, two second micro-motion frames 131 are configured, and the lifting parts 133 provided on each second micro-motion frame 131 form a lifting point. Therefore, two lifting points can be formed in the first direction x, which helps to realize the flipping of the photovoltaic module during the installation process.

[0090] Thus, the two lifting parts 133 can form two lifting points in the second direction y. By adjusting, the moving speed of the second micro-motion frame 131 and the moving speed of the first micro-motion frame 121 in each trolley module 10 are different, which helps to tilt and rotate the photovoltaic module in the horizontal and vertical directions, and realize the tilted installation of the photovoltaic module.

[0091] In a specific implementation, the second micro-motion mechanism 13 and the first micro-motion mechanism 12 achieve relative movement through a second drive mechanism. Specifically, the second drive mechanism includes at least one second drive module 1321. Figures 1 to 4The illustrated vehicle module 10 includes two second drive modules 1321 in its second drive mechanism. Figures 5 to 7 The illustrated vehicle module 10 includes a second drive module 1321 as its second drive mechanism.

[0092] The second drive module 1321 includes a second power mechanism 13211, a second gear 13212, and a second rack 13213. The second power mechanism 13211 is mounted on one of the second support portion 1212 and the second support portion 1311. The second gear 13212 is mounted on one of the corresponding second support portion 1212 and the corresponding second support portion 1311, and is connected to the second power mechanism 13211 for rotation under the drive of the second power mechanism 13211. The second rack 13213 is mounted on the other of the corresponding second support portion 1212 and the corresponding second support portion 1311, and meshes with the second gear 13212. Power transmission via the meshing of the second gear 13212 and the second rack 13213 achieves a larger transmission ratio within a smaller space, resulting in a smaller size for the second drive module 1 and contributing to a more compact and miniaturized overall structure of the vehicle 1. Furthermore, the gear and rack transmission method can ensure a constant transmission ratio, making the power transmission stable and reliable, with high precision output speed and torque, which helps to improve the accuracy of the second micro-motion mechanism 13 in fine-tuning the position of the photovoltaic module in the second direction y.

[0093] The second power mechanism 13211 can be a motor, or a three-in-one motor-reducer integrating a motor, reducer and encoder, or other mechanisms with driving functions.

[0094] It should be noted that the second drive module 1321 can adopt the same structure as the first drive module 1221. For example, the second drive module 1321 may include a second power mechanism 13211, a drive sprocket, a driven sprocket, and a chain. Alternatively, the second drive module 1321 may include a second power mechanism 13211, a drive wheel, a driven wheel, and an annular belt. Yet another example is that the second drive module 1321 may include a second power mechanism 13211, a worm gear, and a worm. For a detailed description of the second drive module 1321, please refer to the description of the first drive module 1221; it will not be repeated here. The use of terms like "first" and "second" in the descriptions of the first drive module 1221, first power mechanism 12211, second drive module 1321, and second power mechanism 13211 is for illustrative purposes only and to distinguish the described objects. It does not imply any order or indicate a specific limitation on the number of devices in this embodiment. In practice, the structures of the first drive module 1221 and second drive module 1321 can be identical, and the structures of the first power mechanism 12211 and second power mechanism 13211 can also be identical, depending on actual needs. For example, both the first power mechanism 12211 and second power mechanism 13211 may use a three-in-one geared motor. The first drive module 1221 and second drive module 1321 are identical, both including a three-in-one geared motor, gears, and racks.

[0095] In some embodiments, a second guide mechanism 134 is further included between the second micro-motion frame 131 and the first micro-motion frame 121. The second guide mechanism 134 is disposed on the first micro-motion frame 121 and / or the second micro-motion frame 131 for guiding the second micro-motion frame 131 to move relative to the first micro-motion frame 121.

[0096] For example, the second guide mechanism 134 includes a second slide rail 1341 and a second slider 1342 adapted to the second slide rail 1341. The second slide rail 1341 is disposed on one of the first micro-motion frame 121 and the second micro-motion frame 131, and the second slider 1342 is disposed on the other of the first micro-motion frame 121 and the second micro-motion frame 131.

[0097] Among them, Figure 6 and Figure 7 In this example, the second slide rail 1341 is disposed on the first micro-motion frame 121, and the second slider 1342 is disposed on the second micro-motion frame 131. Specifically, the second slide rail 1341 is disposed on the second bearing part 1212, and the second slider 1342 is disposed on the second support part 1311. At this time, the second guide mechanism 134 serves to guide the movement of the second micro-motion frame 131 relative to the first micro-motion frame 121, and also serves to suspend the second micro-motion frame 131 on the first micro-motion frame 121.

[0098] For example, combining Figures 2 to 4The second guide mechanism 134 includes at least one second guide wheel, which is disposed on the second micro-motion frame 131. The number of second guide wheels can be one or more; the figure illustrates two second guide wheels as an example.

[0099] In some embodiments, the first micro-motion mechanism 12 adjusts the position of the photovoltaic module within a range of ±500mm in the first direction x. The second micro-motion mechanism 13 adjusts the position of the photovoltaic module within a range of ±500mm in the second direction y.

[0100] In practical implementation, the technical features described in one or more of the above embodiments can be combined according to actual needs and where technically feasible, to obtain a vehicle 1 that meets the actual needs. To facilitate those skilled in the art to better understand and implement the technical solution of this application, the specific structural forms that vehicle 1 may present are described below through two typical application scenarios.

[0106] Each second support portion 1212 is provided with a second micro-motion mechanism 13. Specifically, the second micro-motion frame 131 in the second micro-motion mechanism 13 includes two suspension portions 1312 and two plate-shaped second support portions 1311. The two suspension portions 1312 are spaced apart between the two second support portions 1311 and are respectively connected to the upper ends of the two second support portions 1311.

[0112] The first drive mechanism 122 includes two first drive modules 1221. Each first support part 1211 is provided with a first drive module 1221, so that the two first drive modules 1221 can drive the first support part 1211 to move relative to the first load-bearing part 111, thereby improving the smoothness and stability of the movement of the first support frame 111 relative to the frame 11.

[0113] A second micro-motion mechanism 13 is provided on the second support portion 1212. The second micro-motion frame 131 in the second micro-motion mechanism 13 includes two suspension portions 1312 and two plate-shaped second support portions 1311. The surfaces of the plate-shaped second support portions 1311 extend along the second direction y. The two suspension portions 1312 are spaced apart between the two second support portions 1311 and are respectively connected to the upper ends of the two second support portions 1311. The two suspension portions 1312 are suspended on the second support portion 1212. The second support portion 1212 is located between the two second support portions 1311.

[0114] The second micro-motion mechanism 13 further includes a second guide mechanism 134. The second guide mechanism 134 includes a second slide rail 1341 and a second slider 1342 adapted to the second slide rail 1341. The second support portion 1212 is provided with a second slide rail 1341 on its end face facing each second support portion 1311.

The suspension portion 1312 can be a shaft, and the second slider 1342 can be a wheel sleeved on the suspension portion 1312 and rotating relative to the suspension portion 1312.

[0115] In both application scenarios one and two described above, the lower ends of the two second support portions 1311 are connected to two lifting portions 133. The two lifting portions 133 are arranged at intervals along the second direction y and are located between the two second support portions 1311. The lifting portions 133 can be pulleys.

[0116] In both application scenarios one and two described above, the second drive mechanism in the second micro-motion mechanism 13 includes a second drive module 1321. For a detailed description of the second drive module 1321, please refer to the description in the above embodiments.

[0117] In application scenarios one and two described above, the first micro-motion mechanism 12 may further include two first guide mechanisms 123. For a detailed description of the structure of the first drive mechanism 122 and the first guide mechanism 123, please refer to the relevant descriptions in the above embodiments; they will not be repeated here.

[0118] In specific implementation, combined with Figure 8 and Figure 9 Based on any of the above embodiments, the trolley 1 further includes an anti-sway mechanism 20, which includes an anti-sway drive mechanism 21 and an anti-sway rope 22. The anti-sway drive mechanism 21 is connected to the frame 11. The first end of the anti-sway rope 22 is connected to the anti-sway drive mechanism 21, and the second end of the anti-sway rope 22 is used to connect to the lifting device 3. The anti-sway drive mechanism 21 is used to adjust the tension of the anti-sway rope 22.

[0119] In a specific implementation, the anti-sway drive mechanism 21 may include a third power mechanism 211 and a drum 212. The third power mechanism 211 can drive the drum 212 to rotate.

[0120] The third power mechanism 211 is fixedly connected to the frame 11. For example, the third power mechanism 211 is fixedly connected to the bottom of the frame 11.

[0121] The third power mechanism 211 can be a motor, a three-in-one motor-reducer integrating a motor, reducer, and encoder, or other mechanisms with driving functions.

[0122] The first end of the anti-sway rope 22 is connected to the drum 212, and the second end of the anti-sway rope 22 is used to connect to the lifting device 3. Driven by the third power mechanism 211, the drum 212 rotates forward to tighten the anti-sway rope 22 and wind it around the drum 212. Driven by the third power mechanism 211, the drum 212 rotates in the reverse direction to loosen the anti-sway rope 22. Alternatively, the drum 212 rotates in the reverse direction driven by the third power mechanism 211 to tighten the anti-sway rope 22 and wind it around the drum 212. Driven by the third power mechanism 211, the drum 212 rotates forward to loosen the anti-sway rope 22.

[0123] In some embodiments, the lifting device 3 is provided with a fixing part 23, which is used to connect the anti-sway rope 22. The anti-sway rope 22 can be a steel wire rope or other ropes with a certain degree of flexibility and good load-bearing capacity.

[0124] Each vehicle module 10 is equipped with two anti-sway mechanisms 20. The two anti-sway mechanisms 20 are arranged along the width direction of the photovoltaic module.

[0125] exist Figure 8 and Figure 9 In this illustration, a trolley 1 comprising two trolley modules 10, each trolley module 10 equipped with two anti-sway mechanisms 20, is used as an example. The two anti-sway mechanisms 20 located on the same side of each trolley module 10 form a group. That is, along the width direction of the photovoltaic module, the group relatively closer to the main trolley 2 is designated as the first group of anti-sway mechanisms 20, and the group relatively farther from the main trolley 2 is designated as the second group of anti-sway mechanisms 20. Thus, when the lifting device 3 deviates from its center position and moves away from the main trolley 2, the first group of anti-sway mechanisms 20 pulls the lifting device to resist the deviance. When the lifting device 3 deviates from its center position and moves closer to the main trolley 2, the second group of anti-sway mechanisms 20 pulls the lifting device 3 to resist the deviance, thereby achieving the anti-sway effect of the lifting device 3, ensuring that the lifting device 3 remains stably in the center position without significant swaying.

[0126] This application also provides a photovoltaic installation device 100 including: a main vehicle 2, a hoist 3, and a trolley 1. The trolley 1 adopts the trolley 1 provided in any of the above embodiments. For more details on the specific structure and working principle of the trolley 1, please refer to the above embodiments, which will not be repeated here.

[0127] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this utility model disclosure, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this utility model disclosure are intended to be illustrative and not limiting, unless otherwise stated. In practice, one or more technical features of the dependent claims may be combined with the technical features of the independent claims as needed and where technically feasible, and the technical features from the respective independent claims may be combined in any suitable manner rather than solely by the specific combinations listed in the claims.

[0128] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
