[0056] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0057] The principle of the lifting device 1 proposed in this application will be explained in detail below:

[0058] In related technologies, the installation process of photovoltaic brackets involves installing the side support structure and the middle support structure, then tensioning the component cables and installing the photovoltaic modules on the component cables. The installation of photovoltaic modules is a high-altitude operation, which has low installation efficiency, high cost, and high risk.

[0059] To solve this technical problem, this application provides a lifting device 1, which is described below with reference to... Figures 1-14 The lifting device 1 according to an embodiment of this application is described.

[0060] like Figures 1-4 As shown, the lifting device 1 of this application embodiment is applied to the construction of photovoltaic system 1000 and includes: walking device 10, lifting device 20, support device 30 and driving component 40.

[0061] The lifting device 1 is used to move on the construction ground via the walking device 10.

[0062] In this embodiment, the walking device 10 has functions such as walking forward, backward, left, right, diagonal walking, and parking.

[0063] like Figure 3 As shown, the lifting device 20 includes a first part 21 and a second part 22.

[0064] The first part 21 is installed on the walking device 10.

[0065] Part 22 can be raised relative to Part 1 21.

[0066] In this embodiment, the lifting device 20 can be a nested frame structure with good stability. The second part 22 is nested in the first part 21 or the second part 22 is fitted outside the first part 21. The lifting device 20 is equipped with a servo drive mechanism, which drives the second part 22 to lift relative to the first part 21.

[0067] The servo drive mechanism can be an electric cylinder or a hydraulic cylinder, etc., to improve the synchronization of the lifting and lowering of the second part 22.

[0068] In some embodiments, since the photovoltaic brackets 300 of the photovoltaic system 1000 have different heights, the lifting device 20 can be a nested frame structure with three or more levels. The second part 22 can also adopt a scissor fork structure to adapt to photovoltaic brackets 300 of different heights. The specific number of nesting levels of the lifting device 20 can be set according to actual installation requirements.

[0069] The support device 30 is used to install the component cable 100 of the photovoltaic system 1000 and the photovoltaic module 200. The support device 30 is hinged to the second part 22.

[0070] like Figures 1-4 As shown, the drive member 40 is connected between the second part 22 and the support device 30, and the drive member 40 is used to drive the support device 30 to rotate about the hinge axis.

[0071] In this embodiment, the driving member 40 is connected between the second part 22 and the support device 30. The support device 30 is hinged to the second part 22. The driving member 40 can drive the support device 30 to rotate around the hinge axis with the second part 22 to adjust the rotation of the support device 30 so as to adjust the appropriate angle for installation on the photovoltaic bracket 300 when installing the component cable 100 and the photovoltaic module 200 or lifting the photovoltaic module 200.

[0072] For example, the drive unit 40 may be composed of a tilting cylinder, which can drive the support device 30 to rotate within the range of 0 to 90°.

[0073] In some embodiments, the rotation range of the drive member 40 driving the support device 30 can be set according to actual installation requirements.

[0074] In related technologies, the installation process of photovoltaic brackets involves installing the side support structure and the middle support structure, then tensioning the component cables and installing the photovoltaic modules on the component cables. The lower edge of the photovoltaic modules is set at a certain height above the ground, making the installation of photovoltaic modules a high-altitude operation. The installation is relatively difficult, and the photovoltaic modules are large in size and weight, resulting in low installation efficiency, high cost, and high risk.

[0075] In this embodiment, the lifting device 1 moves from the construction ground to the vicinity of the photovoltaic bracket 300 of the photovoltaic system 1000 via the walking device 10. With the support device 30 in a position close to the construction ground, the component cable 100 is installed on the support device 30, the photovoltaic module 200 is installed on the support device 30, and the photovoltaic module 200 is connected to the component cable 100. The component cable 100 and the photovoltaic module 200 can be installed at a low position, which is less difficult and more efficient. The support device 30 is driven to rotate around the hinge axis to a suitable tilt angle by the driving component 40, and the second part 22 is driven to rise by the lifting device 20 to raise the photovoltaic module 200 to a preset height. The lifting device 1 is then moved to the bottom of the photovoltaic bracket 300, the component cable 100 is aligned with its anchoring position, the component cable 100 is tensioned and anchored, and then the lifting device 1 is moved out to complete the installation of the photovoltaic module 200. There is less high-altitude work and the safety is higher.

[0076] According to the lifting device 1 provided in the embodiments of this application, the component cable 100 and photovoltaic module 200 are installed on the support device 30 when the support device 30 is in a position close to the construction ground, so as to realize the low-position installation of the component cable 100 and photovoltaic module 200. The angle adjustment and lifting of the photovoltaic module 200 are realized through the drive component 40 and the lifting device 20. The installation of the photovoltaic module 200 is less difficult, the installation efficiency is higher, the cost is lower, and there is less high-altitude work, and the safety is higher.

[0077] In some embodiments, such as Figures 2-4 As shown, the support device 30 may include a support frame 31 and a mounting frame 32.

[0078] The support frame 31 is hinged to the second part 22.

[0079] Mounting bracket 32 ​​is used to mount the component cable 100 and photovoltaic module 200 of photovoltaic system 1000. Mounting bracket 32 ​​is slidably mounted on support bracket 31.

[0080] In this embodiment, the support frame 31 is hinged to the second part 22 of the lifting device 20. The support frame 31 is driven to rotate around the hinge axis to a suitable tilt angle by the driving member 40. The mounting frame 32 is slidably mounted on the support frame 31. The mounting frame 32 can slide along the width direction of the support frame 31 to reduce the height of the component cable 100 and the photovoltaic module 200. The installation difficulty of the component cable 100 and the photovoltaic module 200 is relatively low.

[0081] According to the lifting device 1 provided in the embodiments of this application, the installation of the component cable 100 and photovoltaic module 200 is relatively easy and efficient because the mounting frame 32 is slidably installed on the support frame 31.

[0082] In some embodiments, the support frame 31 may include a base and a sliding assembly.

[0083] The base is hinged to the second part 22 and the drive element 40.

[0084] The base can be made of materials such as aluminum alloy, stainless steel, hot-dip galvanized steel or composite materials, and no specific limitation is made in this embodiment.

[0085] The sliding assembly is mounted on the base, and the mounting bracket 32 ​​is mounted on the sliding assembly to facilitate sliding along the width direction of the base.

[0086] In this embodiment, the sliding assembly can be a telescopic fork structure. The sliding assembly is installed on the base and includes a multi-stage fork body. The fork body can move along the width direction of the base. The mounting bracket 32 ​​is installed in the multi-stage fork body of the sliding assembly and can move to the farthest stage fork body.

[0087] According to the lifting device 1 provided in the embodiments of this application, a mounting frame 32 is installed on the moving part of the sliding assembly so that the mounting frame 32 can slide and realize the low-position installation of photovoltaic modules 200.

[0088] In some embodiments, the sliding assembly may include multiple levels.

[0089] Multiple levels can be relatively scalable.

[0090] Each sliding assembly slides along the width of the base and is fitted inside the previous sliding assembly. The mounting bracket 32 ​​is installed on the last sliding assembly.

[0091] In this embodiment, the sliding assembly can be a multi-level nested slide rail structure. The sliding assembly consists of multiple nested slide rails, and the slide rails can move along the width direction of the base. The outermost slide rail is installed on the base, and the mounting bracket 32 ​​is installed on the innermost slide rail of the sliding assembly.

[0092] According to the lifting device 1 provided in the embodiments of this application, by setting up multi-level sliding fittings, the mounting frame 32 can be slidable over a large range, which can be adapted to the installation of photovoltaic modules 200 in different terrains or by different personnel, and has good versatility.

[0093] In some embodiments, the sliding assembly may include a slide rail.

[0094] Mounting bracket 32 ​​is equipped with a slider, which is slidably mounted on a slide rail.

[0095] In this embodiment, the sliding assembly can be a long slide rail structure. The mounting frame 32 is provided with a slider, which is slidably mounted on the slide rail. The mounting frame 32 slides relative to the support frame 31 through the sliding cooperation between the slider and the slide rail.

[0096] According to the lifting device 1 provided in the embodiments of this application, by setting the sliding assembly as a slide rail slider structure, the mounting frame 32 can be slidable within a large range, which can be adapted to the installation of photovoltaic modules 200 in different terrains or by different personnel, and has good versatility.

[0097] In some embodiments, such as Figure 5 As shown, the mounting bracket 32 ​​may include a main frame 321 and a positioning part 322.

[0098] The positioning part 322 is located on the main frame 321.

[0099] The main frame 321 and the positioning part 322 can be made of materials such as aluminum alloy, stainless steel, hot-dip galvanized steel or composite materials. No specific restrictions are made in this embodiment. The materials of the main frame 321 and the positioning part 322 can be the same or different.

[0100] The photovoltaic module 200 is installed on the main frame 321, and the module cable 100 is adapted to extend along the positioning part 322.

[0101] In this embodiment, the positioning part 322 is used to support the component cable 100, so that the component cable 100 is placed in a fixed position, and the main frame 321 is used to support the photovoltaic module 200, so that the mounting hole position of the photovoltaic module 200 is adapted to the component cable 100, resulting in high installation efficiency.

[0102] According to the lifting device 1 provided in the embodiments of this application, by setting a positioning part 322 on the main frame 321, the installation efficiency of the photovoltaic module 200 and the module cable 100 is high and the installation difficulty is low.

[0103] In some embodiments, the positioning portion 322 may include a plurality of protrusions.

[0104] like Figure 5 As shown, multiple protrusions are spaced apart, and component cable 100 is supported on the protrusions.

[0105] In this embodiment, multiple protrusions are spaced apart and distributed on the mounting frame 32. The protrusions are used to support the component cable 100, so that the component cable 100 is placed in a fixed position. The protrusions are small in size, which ensures the support of the component cable 100 without taking up too much space. The cost is low and the integration is good.

[0106] It should be noted that the height, thickness and number of protrusions can be set according to the length, diameter or other parameters of component cable 100 during actual installation, or according to the frame width and number of mounting bracket 32. No specific restrictions are imposed in this embodiment.

[0107] The lifting device 1 provided in the embodiments of this application has a small size, low cost, and good integration by setting multiple protrusions that are spaced apart.

[0108] In some embodiments, the plurality of protrusions may be divided into two groups.

[0109] The multiple protrusions are divided into two groups along the width direction of the main frame 321.

[0110] Each set of protrusions is set along the length of the main frame 321.

[0111] It is understood that the spacing between the two sets of protrusions along the width direction of the main frame 321 can be set according to actual installation requirements, and no specific restrictions are imposed in this embodiment.

[0112] like Figure 5As shown, in this embodiment, the two sets of protrusions can be spaced apart along the width direction of the main frame 321. Each set of protrusions contains multiple protrusions arranged along the length direction of the main frame 321. The two component cables 100 are respectively supported on the two sets of protrusions. The photovoltaic module 200 is connected to the two component cables 100. The stability is good when the photovoltaic module 200 is installed and used.

[0113] According to the lifting device 1 provided in the embodiments of this application, two sets of protrusions are set to support the two component cables 100, so that the stability is better when installing and using the photovoltaic module 200.

[0114] In some embodiments, the connection between the drive member 40 and the second part 22 and the support device 30 can be at least one of the following forms:

[0115] Firstly, such as Figure 2 and Figure 3 As shown, the drive member 40 can be hinged to the second part 22 and the support device 30.

[0116] In this embodiment, one end of the driving member 40 is hinged to the second part 22, and the other end of the driving member 40 is hinged to the support device 30. The length of the driving member 40 is adjustable. When the length of the driving member 40 is adjusted, it pushes the support device 30 to rotate around the hinge axis. At the same time, the hinge point between the driving member 40 and the second part 22 rotates accordingly to adapt to the change in the tilt angle of the support device 30.

[0117] Secondly, the driving component 40 is fixedly connected to the second part 22, and the driving component 40 is slidably hinged to the support device 30 along the width direction of the support device 30.

[0118] In this embodiment, one end of the driving member 40 is fixedly connected to the second part 22, and the other end of the driving member 40 is hinged to a slider. The slider can slide along the width direction of the support device 30. When the length of the driving member 40 is adjusted, it pushes the support device 30 to rotate around the hinge axis. At the same time, the slider slides along the width direction of the support device 30 and rotates around the hinge axis at the hinge point with the driving member 40.

[0119] According to the lifting device 1 provided in the embodiments of this application, the connection method between the driving component 40 and the second part 22 and the support device 30 is set so as to realize the change of the tilt angle of the support device 30.

[0120] In some embodiments, the walking device 10 may include a plurality of walking parts 11.

[0121] The walking part 11 can have various structures. In this embodiment, for example... Figure 3 As shown, the traveling part 11 can be a roller, and multiple rollers are provided.

[0122] The first part 21 is installed on the running gear 11.

[0123] In this embodiment, the walking device 10 can be composed of two diagonally arranged vertical drive assemblies or four vertical drive assemblies. The walking device 10 is equipped with two or four omnidirectional wheels and has the functions of walking forward, backward, left and right, diagonal walking and parking.

[0124] According to the embodiments of this application, the lifting device 1 is provided with multiple walking parts 11 to facilitate the movement of the lifting device 1 and its installation near the photovoltaic bracket 300. It has high flexibility and the multiple walking parts 11 have good stability.

[0125] The lifting device 1 provided in this application embodiment can be constructed using the following method.

[0126] like Figure 13 As shown, the construction method includes steps 60, 70, 80 and 90.

[0127] like Figure 7 As shown, in step 60, with the support device 30 in a position close to the construction ground, the component cable 100 is installed on the support device 30.

[0128] In this embodiment, the walking device 10 moves on the construction ground to the vicinity of the photovoltaic support 300 of the photovoltaic system 1000. When the support device 30 is in a position close to the construction ground, the component cable 100 is installed on the support device 30.

[0129] Understandably, at this time, the support device 30 is in a state that is close to perpendicular to the ground, the installation difficulty of the component cable 100 is relatively low, the requirements for construction personnel and equipment are low, and the installation efficiency is high.

[0130] like Figure 4 , Figure 6 and Figure 8 As shown, in step 70, the photovoltaic module 200 is installed on the support device 30 and connected to the module cable 100.

[0131] In this embodiment, the photovoltaic module 200 is installed on the support device 30 and connected to the module cable 100. The module cable 100 and the photovoltaic module 200 can be installed at a low position, which makes the installation less difficult and the installation efficiency higher.

[0132] like Figure 9 and Figure 10 As shown, in step 80, the support device 30 is rotated to a suitable tilt angle by the drive component 40 and the second part 22 is raised by the lifting device 20 to lift the photovoltaic module 200.

[0133] In this embodiment, after all photovoltaic modules 200 are fastened, the support device 30 is driven by the drive component 40 to rotate around the hinge axis to a suitable tilt angle, so as to avoid interference between the upper component cable 100 and the middle beam of the photovoltaic bracket 300 when the photovoltaic module 200 is moved after being lifted, and the second part 22 is driven to rise by the lifting device 20 to lift the photovoltaic module 200 to a preset height.

[0134] like Figure 11 and Figure 12 As shown, in step 90, the fixed component cable 100 is attached to the photovoltaic bracket 300 of the photovoltaic system 1000.

[0135] In this embodiment, the lifting device 1 is moved below the photovoltaic bracket 300, the component cable 100 is aligned with its anchoring position, the component cable 100 is tensioned and anchored, and then the lifting device 1 is moved out to complete the installation of the photovoltaic module 200.

[0136] It should be noted that each span of the photovoltaic support 300 requires at least one of these lifting devices 1, and the space formed between the two side columns along the length of the component cable 100 is one span.

[0137] According to the construction method provided in the embodiments of this application, the component cable 100 and multiple photovoltaic modules 200 are installed on the support device 30 when the support device 30 is in a position close to the construction ground, thereby achieving low-level installation of the component cable 100 and multiple photovoltaic modules 200. The angle adjustment and lifting of multiple photovoltaic modules 200 are achieved through the drive component 40 and the lifting device 20. The installation of photovoltaic modules 200 is less difficult, the installation efficiency is higher, the cost is lower, and there is less high-altitude work, resulting in higher safety.

[0138] In some embodiments, the support device 30 may include: a support frame 31 hinged to the second part 22; and a mounting bracket 32 ​​for mounting the photovoltaic system 1000 component cable 100 and the photovoltaic module 200, which is slidably mounted on the support frame 31.

[0139] Step 70, installing the photovoltaic module 200 onto the support device 30 and connecting it to the module cable 100, may include:

[0140] like Figure 14 As shown, in step 71, the photovoltaic module 200 is installed on the support device 30, and the mounting bracket 32 ​​is slid along the width direction of the support frame 31 to connect the photovoltaic module 200 with the multiple module cables 100.

[0141] In this embodiment, the mounting bracket 32 ​​is slidably mounted on the support frame 31. The mounting bracket 32 ​​can slide along the width direction of the support frame 31 to reduce the height of the multiple component cables 100 and the photovoltaic module 200, thus making the installation of the multiple component cables 100 and the photovoltaic module 200 easier.

[0142] In some embodiments, multiple component cables 100 and photovoltaic modules 200 can be installed on the support device 30 at other locations. Then, the lifting device 1 is transported to the vicinity of the photovoltaic bracket 300 of the photovoltaic system 1000 by moving the walking device 10 on the construction ground. Then, the support device 30 is driven to rotate around the hinge axis to a suitable tilt angle by the drive member 40 and the second part 22 is driven to rise by the lifting device 20 to lift the photovoltaic module 200 to a preset height and then install it on the photovoltaic bracket 300.

[0143] In some embodiments, the lifting device 1 can be transported to the vicinity of the photovoltaic bracket 300 of the photovoltaic system 1000 by moving the walking device 10 on the construction ground first, and then the multiple component cables 100 and the photovoltaic module 200 can be installed on the support device 30. Then, the support device 30 can be driven to rotate around the hinge axis to a suitable tilt angle by the driving component 40 and the second part 22 can be driven to rise by the lifting device 20 to lift the photovoltaic module 200 to a preset height and then install it on the photovoltaic bracket 300.

[0144] For example, the photovoltaic module 200 and the module cable 100 can be connected by the connecting structure 50. First, the adjacent photovoltaic module 200 is connected by the connecting structure 50. Then, the mounting frame 32 is raised to a suitable height to connect the lower module cable 100 with the photovoltaic module 200. Then, the mounting frame 32 is slid to connect the upper module cable 100 with the photovoltaic module 200. The construction workers stand on the ground to place and install the module cable 100 and the photovoltaic module 200. The installation is relatively easy and safe.

[0145] In some embodiments, such as Figure 6 As shown, the connection structure 50 may include a pressure plate 51 and a connector 52. The pressure plate 51 is used to connect adjacent photovoltaic modules 200, and the connector 52 is installed on the pressure plate 51 and is used to connect the module cable 100.

[0146] According to the construction method provided in the embodiments of this application, by setting the mounting frame 32 to slide on the support frame 31, the installation difficulty of the component cable 100 and the photovoltaic module 200 is low, the installation efficiency is high, and there is less high-altitude work, resulting in higher safety.
