[0035] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] Reference Figure 1-Figure 3 , Figure 6 , Figure 1 The photovoltaic transport vehicle maintenance device improves the status of the photovoltaic transport vehicle after lifting, Figure 2 , Figure 3 The maintenance device for the photovoltaic transporter improves the status of the photovoltaic transporter.

[0037] The utility model provides a photovoltaic transport vehicle maintenance device, comprising: a support frame 1, a driving mechanism 2 and a lifting mechanism 3;

[0038] The driving mechanism 2 is arranged on the top of the supporting frame 1, the lifting mechanism 3 is arranged in the supporting frame 1, the driving mechanism 2 is connected with the lifting mechanism 3, the photovoltaic transport vehicle 4 is engaged with the lifting mechanism 3, and the driving mechanism 2 drives the lifting mechanism 3 and the photovoltaic transport vehicle 4 to move along the first direction X, and the first direction X is a direction perpendicular to the ground;

[0039] The lifting mechanism 3 includes two L-shaped lifting plates 31 and a support plate 32 connected to the lifting plates 31. The lifting plates 31 are arranged opposite to each other along the second direction Y, and the second direction Y intersects with the first direction X. A tray 41 is provided on the top of the photovoltaic transport vehicle 4. There is a gap between the tray 41 and the photovoltaic transport vehicle 4 along the first direction X, and the lifting plates 31 are engaged with the tray 41 through the gap.

[0040] Travel switches 5 are provided at both ends of the support frame 1 along the first direction X. The travel switches 5 are electrically connected to the drive mechanism 2. Along the first direction X, the orthographic projections of the travel switches 5 are located within the orthographic projections of the support plate 32. When the lifting mechanism 3 contacts the travel switches 5, the drive mechanism 2 stops driving.

[0041] It should be noted that, combined with Figure 4 In this embodiment, the support frame 1 includes four support rods 11 extending along the first direction X, and the reinforcing rod 12 connects two adjacent support rods 11. The arrangement of the reinforcing rod 12 makes the support of the support rod 11 more stable. Figure 1 , one reinforcing rod 12 is arranged at the top of the support rod 11, and the other three reinforcing rods 12 are arranged at the bottom of the support rod 11. The reinforcing rod 12 arranged at the top of the support rod 11 forms an opening with the ground, and the photovoltaic transport vehicle 4 enters the support frame from the opening. The entry direction of the photovoltaic transport vehicle 4 is the third direction Z, and the second direction Y intersects with the third direction Z and the first direction X; two lifting plates 31 are arranged relatively along the second direction Y, and the lifting plates 31 are L-shaped. The lifting plates 31 are engaged with the tray 41 through the gap between the tray 41 and the photovoltaic transport vehicle 4, that is, the lifting plates 31 can hook the tray 41, and the support plate 32 is connected to the driving mechanism 2, and the driving mechanism 2 drives the support plate 32 to move along the first direction X, thereby driving the lifting plates 31 and the photovoltaic transport vehicle 4 to rise and fall.

[0042] The travel switch is an electrical switch used to limit the movement limit position of the mechanical equipment. When the mechanical equipment runs to a specific position, the contact of the travel switch will be triggered by the mechanical structure to generate a switch signal, thereby controlling the operation state of the equipment. The support frame 1 is provided with a travel switch 5 at both ends along the first direction X. The travel switch 5 is electrically connected to the lifting mechanism 3. Along the first direction X, the positive projection of the travel switch 5 is located within the positive projection of the support plate 32 to ensure that the lifting mechanism 3 can contact the travel switch 5; specifically, the end of the support frame 1 away from the ground is provided with an upper travel switch 51, and the end of the support frame 1 close to the ground is provided with a lower travel switch 52; when the lifting mechanism 3 rises, the lifting mechanism 3 runs to a preset height, the support plate 32 triggers the upper travel switch 51, and the drive mechanism 2 automatically stops the brake and self-locks; when the lifting mechanism 3 descends, the photovoltaic trolley falls to the ground, the lifting plate 31 triggers the lower travel switch 52, and the drive mechanism 2 automatically stops the brake and self-locks. By setting the travel switch 5, the lifting mechanism 3 is limited to avoid bumping the photovoltaic transporter 4. In this embodiment, the travel switch 5 can be a conventional domestic travel switch LX19 series or an imported travel switch WL series, HL series, etc. in the prior art.

[0043] It can be understood that in this embodiment, the support frame 1 is used to support the driving mechanism 2 and the lifting mechanism 3. The lifting mechanism 3 is based on the structural design of the photovoltaic transport vehicle 4, so that the tray 41 of the photovoltaic transport vehicle 4 can be engaged between the two L-shaped lifting plates 31. The driving mechanism 2 drives the lifting mechanism 3 to rise and fall, thereby driving the photovoltaic transport vehicle 4 to rise and fall; when inspecting the bottom of the photovoltaic transport vehicle 4, the lifting mechanism 3 lifts the photovoltaic transport vehicle 4 to 0.8 meters above the ground, and the maintenance personnel can conveniently inspect the bottom of the photovoltaic transport vehicle 4. Compared with manually turning over the photovoltaic transport vehicle 4, the photovoltaic transport vehicle maintenance device has the advantages of high efficiency and high safety, thereby improving production efficiency and reducing labor intensity. By setting the travel switch 5 to control the operating position of the lifting mechanism 3, the lifting position of the photovoltaic transport vehicle 4 is ensured to be accurate and avoid collisions.

[0044] In some optional embodiments, combined with Figure 1 , Figure 4 , Figure 5 A fixing plate 13 is provided on the top of the support frame 1, the fixing plate 13 is fixedly connected to the support frame 1, and a mounting hole 131 is provided on the fixing plate 13 and passes through the fixing plate 13 along the first direction X;

[0045] The driving mechanism 2 is disposed on a side of the fixing plate 13 away from the ground. The driving mechanism 2 is an electric winch 20 . A connecting rope 22 of the electric winch 20 passes through the mounting hole 131 and is connected to a hook 23 of the electric winch 20 .

[0046] It should be noted that the electric winch 20 includes a motor 21, a connecting rope 22, a hook 23 and a power-off brake 24. The hook 23 is connected to the lifting ring 33 and is used to lift the entire lifting mechanism 3 and the photovoltaic transport vehicle 4. The power-off brake 24 has a power-off self-locking brake function to ensure that it does not fall during lifting and plays a safety protection role.

[0047] Specifically, the fixing plate 13 is fixed to the top of the supporting frame 1 , and the fixing plate 13 is used to support the driving mechanism 2 . A reinforcing rib 321 extending along the second direction Y may also be provided on the fixing plate 13 to prevent the fixing plate 13 from being easily deformed.

[0048] In some optional embodiments, combined with Figure 2 , Figure 7 A lifting ring 33 is provided on one side of the support plate 32 away from the ground, and the lifting ring 33 is detachably connected to the lifting hook 23 .

[0049] It is understandable that the lifting ring 33 can provide a safe and reliable connection during lifting, ensuring stability and safety during operation. By arranging the lifting ring 33 on the side of the support plate 32 away from the ground, the lifting ring 33 is detachably connected to the hook 23, so that the electric winch 20 is connected to the lifting mechanism 3. This connection method avoids the risks that may be caused by using a shackle and improves the reliability of the entire system.

[0050] In some optional embodiments, combined with Figure 2 , Figure 7 A plurality of linear guide rails 6 extending along the first direction X are provided in the support frame 1, and linear bearings 34 are provided at the corners of the support plate 32. The linear bearings 34 are sleeved outside the linear guide rails 6, and the support plate 32 drives the linear bearings 34 to move along the first direction X.

[0051] It should be noted that, in order to ensure stable operation of the lifting device, linear bearings 34 are set at the four corners of the support plate 32. Along the third direction Z, the sum of the widths of the two linear bearings 34 and the connecting plate is less than or equal to the width of the support plate 32.

[0052] It can be understood that by arranging a linear bearing 34 on the support plate 32, the linear bearing 34 is sleeved outside the linear slide rail 6, and the linear slide rail 6 guides the lifting and lowering of the lifting mechanism 3 to avoid the risk of the photovoltaic transport vehicle 4 shaking and falling off during the lifting process.

[0053] In some optional embodiments, referring to Figure 6 The lifting plate 31 includes a first portion 311 and a second portion 312 . The first portion 311 is parallel to the plane where the support plate 32 is located, and the second portion 312 connects the first portion 311 and the support plate 32 . The first portion 311 is also provided with a guide wheel 35 extending along the first direction X.

[0054] It should be noted that, along the second direction Y, both ends of the support plate 32 are provided with a lifting plate 31, and the lifting plate 31 is arranged on the side of the support plate 32 close to the ground, the first part 311 of the lifting plate 31 is parallel to the plane where the support plate 32 is located, the second part 312 connects the first part 311 and the support plate 32, and the first part 311 and the second part 312 constitute an L-shaped lifting plate 32; the tray 41 of the photovoltaic transport vehicle 4 is engaged between the two second parts 312 arranged oppositely along the second direction Y, and the lower edge of the tray 41 is in contact with the first part 312. Along the second direction Y, the interval between the two guide wheels 35 arranged oppositely is equal to the width of the tray 41 of the photovoltaic transport vehicle 4, and the guide wheel 35 limits the tray 41. At the same time, in the process of engaging the tray 41 of the photovoltaic transport vehicle 4 with the lifting plate 31, the guide wheel 35 plays a guiding role to prevent the photovoltaic transport vehicle 4 from deviating from the driving path.

[0055] The working process of the photovoltaic transport vehicle maintenance device in this embodiment includes: the photovoltaic transport vehicle 4 drives into the lifting mechanism 3 along the guide wheel 35, the motor 21 of the electric winch 20 works, the traction connecting rope 22 is slowly lifted, the lifting plate 31 of the lifting mechanism 3 holds the lower edge of the tray 41 of the photovoltaic transport vehicle 4, and the photovoltaic transport vehicle 4 is slowly lifted along the linear slide rail 6 to the specified height to trigger the upper travel switch 51, and the electric winch 20 stops automatically. At this time, the operator can inspect the bottom of the photovoltaic transport vehicle 4. After the inspection is completed, the photovoltaic transport vehicle 4 slowly descends to trigger the lower travel switch 52, the electric winch 20 stops automatically, and the photovoltaic transport vehicle 4 drives out of the photovoltaic transport vehicle maintenance lifting device.

[0056] In some optional embodiments, the guide wheel 35 is a nylon guide wheel 35 .

[0057] It should be noted that the guide wheel 35 can also be a TPR guide wheel 35, a TPU guide wheel 35, a PU guide wheel 35 or a PP guide wheel 35; TPR (thermoplastic elastomer) has good elasticity, wear resistance and aging resistance, TPR material is easy to process and mold, and can be processed by injection molding, extrusion and other methods, with high production efficiency; TPU (thermoplastic polyurethane) material has the advantages of high wear resistance and high strength; PU (polyurethane) material can be made into different hardness grades from soft to hard, and has very good wear resistance; PP (polypropylene) material has high strength and is not easy to age.

[0058] It can be understood that the nylon material has a smooth surface, a small friction coefficient, good wear resistance, and is self-lubricating when used as a movable mechanical component; the self-lubricating property of the nylon guide wheel 35 has a protective effect on the tray 41 of the photovoltaic cart, can reduce wear, and thus extend the service life.

[0059] In some optional embodiments, referring to Figure 1 A plurality of safety gratings 7 extending along a first direction X are provided on the support frame 1 .

[0060] It should be noted that the support frame 1 is also provided with a plurality of control buttons, such as a forward button, a reverse button, a stop button, etc. The control buttons are electrically connected to the drive device, and the control buttons control the start and stop and forward and reverse rotation of the drive device through a programmable logic (PLC) controller; illustratively, when the forward button is pressed, the PLC controller triggers the motor 21 drive device to output forward, and the drive device drives the lifting device to rise; when the reverse button is pressed, the PLC controller triggers the drive device to output reversely, and the drive device drives the lifting device to descend; when the stop button is pressed, the PLC controller triggers the drive device to stop output.

[0061] It is understandable that the safety grating creates a virtual light barrier by emitting a beam of infrared light or laser beam. When an object enters the beam and interrupts the light, the safety grating will immediately trigger a stop signal. The setting of the safety grating can effectively monitor the potential risk of accidental touch. The safety grating 7 is installed on the support rod 11 of the support frame 1 to play a safety protection role and prevent the staff from accidentally pressing the control button when inspecting the photovoltaic transport vehicle 4, causing the photovoltaic transport vehicle 4 to fall. Specifically, the safety grating 7 can be a safety grating of a common brand on the market, such as KEYENCE, SICK, BANNER and ESPE.

[0062] In some optional embodiments, referring to Figure 7 At least one reinforcing rib 321 extending along the second direction Y is provided on a side of the support plate 32 away from the ground.

[0063] It should be noted that the lifting plates 31 are relatively arranged along the second direction Y. Specifically, the lifting plates 31 are arranged at both ends of the support plate 32 in the second direction Y, and the tray 41 of the photovoltaic transport vehicle 4 is engaged between the two relatively arranged lifting plates 31. When the lifting plates 31 are lifted together with the photovoltaic transport vehicle 4, the photovoltaic transport vehicle 4 weighing 144 kg is prone to cause deformation of both ends of the support plate 32; the reinforcement ribs 321 are also arranged along the second direction Y, which improves the strength and bearing capacity of the support plate 32 structure and avoids deformation of both ends of the support plate 32 along the second direction Y. In addition, the setting of the reinforcement ribs 321 can improve the strength without increasing the thickness of the support plate 32 as a whole, thereby reducing the self-weight of the support plate 32 and saving costs.

[0064] In some optional embodiments, the support plate 32 is an aluminum alloy support plate.

[0065] It is understandable that the good plasticity and processability of aluminum alloy materials enable the aluminum alloy support plate 32 to adapt to different design and manufacturing requirements. The density of aluminum alloy is about 1 / 3 of that of copper or steel, but it has a strength close to or exceeding that of high-quality steel. This light but high-strength characteristic allows aluminum alloy to reduce weight while ensuring structural stability and safety; the low-density and high-strength aluminum alloy support plate 32 can reduce its own weight while maintaining sufficient strength, making it easier for the drive device to drive the lifting mechanism 3 and the photovoltaic transport vehicle 4 to rise and fall.

[0066] In some optional embodiments, referring to Figure 7 The support plate 32 is also provided with a plurality of weight-reducing holes 36 penetrating the support plate 32 along the first direction X.

[0067] It can be understood that by providing weight-reducing holes 36 on the support plate 32, the weight of the support plate 32 can be effectively reduced, which not only makes the support plate 32 lighter and easier to carry and install, but the reduced deadweight of the lifting device can also reduce the power or energy required by the driving device to drive the lifting device, thereby helping to reduce energy consumption and reduce operating costs. Figure 7 The eight circular weight-reducing holes 36 shown are for schematic illustration only. The shape, size and position of the weight-reducing holes 36 can be designed and optimized according to specific engineering requirements. Reasonable weight-reducing hole design can improve the stress distribution of the support plate 32, making the entire lifting device 3 more uniform and stable when bearing load.

[0068] It can be seen from the above embodiments that the photovoltaic transport vehicle maintenance device provided by the utility model achieves at least the following beneficial effects:

[0069] The photovoltaic transport vehicle maintenance device provided by the utility model comprises: a support frame, a driving mechanism and a lifting mechanism; the driving mechanism is arranged on the top of the support frame, the lifting mechanism is arranged in the support frame, the driving mechanism is connected to the lifting mechanism, the photovoltaic transport vehicle is engaged with the lifting mechanism, the driving mechanism drives the lifting mechanism and the photovoltaic transport vehicle to move along a first direction, and the first direction is a direction perpendicular to the ground; the lifting mechanism comprises two L-shaped lifting plates and a supporting plate connected to the lifting plates, the lifting plates are arranged relatively along a second direction, and the second direction intersects with the first direction; a tray is arranged on the top of the photovoltaic transport vehicle, along the first direction, there is a gap between the tray and the photovoltaic transport vehicle, and the lifting plate is engaged with the tray through the gap; both ends of the support frame along the first direction are provided with a travel switch, the travel switch is electrically connected to the driving mechanism, along the first direction, the positive projection of the travel switch is located in the positive projection of the support plate, the lifting mechanism contacts the travel switch, and the driving mechanism stops driving. The lifting mechanism lifts the photovoltaic transport vehicle off the ground, and the maintenance personnel can conveniently inspect the bottom, and the photovoltaic transport vehicle maintenance device has the advantages of high efficiency and high safety, thereby improving production efficiency and reducing labor intensity. By setting the travel switch to control the operating position of the lifting mechanism, the lifting position of the photovoltaic transporter is ensured to be accurate and collisions are avoided.
