Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic construction and transportation device. Background Technology

[0002] During the construction of a photovoltaic power station, a large number of photovoltaic panels, brackets, and other components need to be transported from storage points to specific installation locations. This process continues throughout the construction process, placing high demands on the efficiency and reliability of the transport equipment.

[0003] Currently, the most common methods of transportation at construction sites are manual handling or the use of simple hand-pushed flatbed carts. These methods not only consume a lot of manpower, resulting in high labor intensity and low work efficiency, but are also particularly inconvenient for long-distance or large-volume transportation.

[0004] Further analysis of the structure of these simple flatbed trucks reveals that their design fails to adequately consider the unique environment of photovoltaic construction sites and the delicate characteristics of photovoltaic modules. Firstly, their fixed platform dimensions cannot provide effective support for photovoltaic panels of different sizes, making the modules prone to collisions due to shaking or slippage during transport, posing safety hazards. Secondly, these flatbed trucks typically use rigid wheel sets, lacking effective shock absorption and cushioning structures. Construction sites are often uneven, and the bumps and vibrations generated by the vehicles during travel produce severe vibrations. These impacts are directly transmitted to the fragile photovoltaic panels, easily causing internal cracks or even damage, affecting power generation efficiency and lifespan.

[0005] In summary, existing photovoltaic (PV) construction and transportation tools, due to their overly simplified structure, generally suffer from two major drawbacks: insufficient support and stability for components, and poor adaptability to uneven ground. This significantly increases the risk of damage to PV modules during actual transportation, making it difficult to meet the high standards of construction quality and safety required for modern PV power plant construction.

[0006] Therefore, this utility model proposes a photovoltaic construction transfer device to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in photovoltaic construction transfer devices, such as the inability to stably support components of different specifications due to the fixed size of the bearing platform, and the inability to adapt to uneven ground due to the lack of shock absorption structure, resulting in easy impact damage to the components, this utility model aims to provide a photovoltaic construction transfer device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a photovoltaic construction transfer device, including a support plate, multiple casters rotatably connected to the bottom of the support plate, at least one telescopic rod vertically fixed to the support plate, and a placement plate and a sliding plate slidably connected to the telescopic rod.

[0009] The device also includes a width adjustment mechanism and a shock absorption mechanism.

[0010] The placement plate includes at least two sliding extension plates, and the width adjustment mechanism includes a drive motor, a drive gear connected to the drive motor, and racks fixed to the extension plates and meshing with the drive gear.

[0011] Furthermore, a shock-absorbing mechanism is located between the support plate and the caster wheel. This shock-absorbing mechanism includes a spring and a telescopic housing, with a working piston slidably disposed inside the telescopic housing.

[0012] Preferably, the photovoltaic construction transfer device further includes a lifting mechanism, which includes a drive device mounted on a support plate, a roller connected to the drive device, and a wire rope with one end wound around the roller and the other end connected to the placement plate and the sliding plate.

[0013] Preferably, the lifting mechanism further includes a pinion and a large gear. The pinion is connected to the output end of the drive device, and the large gear meshes with the pinion and is coaxially fixed to the drum.

[0014] Preferably, the device further includes a pulley and a guide wheel rotatably mounted on the top of the telescopic rod, with the wire rope passing over the guide wheel and the pulley in sequence.

[0015] Preferably, the shock absorption mechanism further includes a piston rod and a floating piston slidably disposed within the telescopic housing, with the working piston fixedly connected to the piston rod.

[0016] Preferably, the shock absorption mechanism further includes a mounting plate and a mounting base plate. The mounting plate is fixed to the bottom of the support plate, the mounting base plate is fixed to the top of the caster wheel, and the telescopic shell and spring are connected between the mounting plate and the mounting base plate.

[0017] Preferably, the placement plate has a guide groove, and the extension plate slides within the guide groove.

[0018] Preferably, the two extension plates are fitted into the placement plate in an inlay manner.

[0019] This utility model has the following beneficial effects: 1. In this utility model, by setting a width adjustment mechanism composed of a drive motor, a drive gear and a rack, the extension plate is driven to extend and retract synchronously, which solves the problem that the existing transfer tools cannot adapt to different specifications of photovoltaic modules due to the fixed size of the bearing platform, resulting in unstable transportation support. It achieves the technical effect of flexibly adjusting the bearing area and enhancing the device's adaptability to different photovoltaic modules and transportation stability.

[0020] 2. In this utility model, by setting a shock-absorbing mechanism consisting of a spring and a telescopic shell with a working piston inside between the support plate and the caster wheel, the problem of photovoltaic modules being easily damaged by bumps and impacts when transported on uneven construction sites by existing transfer tools is solved. This achieves the technical effect of effectively buffering ground impacts, reducing the risk of damage to photovoltaic modules, and improving the safety of transfer. Attached Figure Description

[0026] To solve the above-mentioned technical problems, the core of the technical solution in this embodiment lies in the width adjustment mechanism and the shock absorption mechanism.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions. As a preferred embodiment, the device further includes a lifting mechanism, which includes a drive device 6 mounted on the support plate 1, a drum 9 connected to the drive device 6, and a wire rope 5 with one end wound around the drum 9 and the other end connected to the placement plate 11 and the sliding plate 10.

The small gear 7 is connected to the output end of the drive device 6, and the large gear 8 meshes with the small gear 7 and is coaxially fixed to the drum 9. As a preferred embodiment, the device further includes a pulley 4 and a guide wheel 3 rotatably mounted on the top of the telescopic rod 2, and the wire rope 5 sequentially... Bypassing guide wheel 3 and pulley 4, in a preferred embodiment, the shock absorption mechanism also includes piston rod 19 and floating piston 21 slidably disposed in telescopic shell 18, with working piston 20 fixedly connected to piston rod 19. In another preferred embodiment, the shock absorption mechanism also includes mounting plate 16 and mounting base plate 17, with mounting plate 16 fixed to the bottom of support plate 1 and mounting base plate 17 fixed to the top of caster wheel 23. Telescopic shell 18 and spring 22 are connected between mounting plate 16 and mounting base plate 17. In another preferred embodiment, placement plate 11 has a guide groove, with extension plate 12 slidably fitted in the guide groove. In yet another preferred embodiment, two extension plates 12 are inlaid into placement plate 11.

[0028] Working principle: When it is necessary to adjust the bearing area to accommodate photovoltaic modules of different sizes, the drive motor 15 set on the placement plate 11 is started. The drive motor 15 drives the drive gear 14 to rotate. Since the drive gear 14 meshes with the racks 13 fixed to the two extension plates 12 respectively, the rotational motion of the drive gear 14 is converted into the linear motion of the racks 13, which pushes the two extension plates 12 to slide out to both sides or slide inward along the guide groove of the placement plate 11 in sync.

[0029] When the height of the support platform needs to be adjusted, the drive device 6 set on the support plate 1 is activated. The drive device 6 drives the large gear 8 to rotate through the small gear 7. The meshing transmission between the small gear 7 and the large gear 8 achieves speed reduction and torque increase. The large gear 8 is coaxially fixed to the drum 9, thereby driving the drum 9 to rotate to wind or release the wire rope 5. The wire rope 5 is guided by the guide wheel 3 and pulley 4 set on the top of the telescopic rod 2, and finally pulls the placement plate 11 and sliding plate 10 connected to the wire rope 5 to rise or fall smoothly along the telescopic rod 2.

[0030] When the device travels on uneven ground, a relative displacement occurs between the mounting plate 16 at the bottom of the support plate 1 and the mounting base plate 17 at the top of the caster wheel 23. This displacement first compresses the spring 22 connected between the mounting plate 16 and the mounting base plate 17. At the same time, the piston rod 19, which is fixedly connected to the working piston 20, drives the working piston 20 to slide inside the telescopic shell 18. The liquid inside the telescopic shell 18 generates hydraulic damping through the piston to dissipate vibration energy. The floating piston 21, which is slidably set inside the telescopic shell 18, is used to adjust the internal volume. Through the synergistic effect of the spring 22 and the telescopic shell 18, vibration and impact from the ground are effectively absorbed.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
