Abstract
Description
[Technical field]
[0001] The utility model belongs to the technical field of photovoltaics, and specifically relates to photovoltaic component construction technology. [Background technology]
[0002] With the vigorous development of the photovoltaic industry, the conversion efficiency and power of photovoltaic modules are getting higher and higher, from the mainstream 200W modules 10 years ago (2014) to the mainstream 600W modules today (2024). With the improvement of the efficiency and power of photovoltaic modules, the area and weight of the modules have also increased accordingly. At present, a 600W double-glass module can reach an area of 2.6 square meters, a length of 2.4 meters, and a weight of more than 30 kilograms. In the context of the increasing size and weight of modules, the traditional installation method is still mainly based on manual handling, which has low installation efficiency and long-term load-bearing and carrying work will cause joint and lumbar injuries to operators.
[0003] In order to reduce the labor intensity, the prior art also uses a trolley to transport photovoltaic modules. The Chinese patent with announcement number CN209064914U discloses a rail trolley for transporting materials of photovoltaic power stations with color steel tile roofs, including a body, two wooden board bases and two guide rails. A rope ring is welded in the middle of the outer wall of the front right angle steel of the body and the middle of the outer wall of the rear right angle steel. The rope ring is connected to one end of the pull rope. Two front edge guards are symmetrically welded on the top side of the front right angle steel of the body. Two side edge guards are symmetrically welded on the top side of the first side right angle steel of the body and the top side of the second side right angle steel of the body; a one-way wheel is provided at each of the four corners of the bottom side of the body; two wooden board bases are arranged parallel to each other on the outside of the color steel tile roof, and a guide rail is laid on the wooden board base. A strip groove for accommodating the one-way wheel is provided in the middle of the upper surface of the guide rail, and the spacing between the two guide rails is adapted to the spacing between the two one-way wheels. However, due to the change in the size of the module, the rail trolley with a fixed wheel track cannot adapt to the changes in the size of the module and the spacing of the guide rails. [Contents of the utility model]
[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a photovoltaic component transport trolley with adjustable wheelbase, which solves the problem that the existing trolley cannot match component installation rails of different widths.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solution: a photovoltaic component transport cart with adjustable wheelbase, comprising a body with a photovoltaic component placement structure, an axle installed on the body, and two wheels respectively installed at both ends of the axle, wherein the axle is provided with a wheelbase adjustment structure for adjusting the wheelbase of the two wheels.
[0006] Preferably, the axle is a hydraulic telescopic rod axle, the wheelbase adjustment structure comprises telescopic rod sections arranged on both sides of the axial direction of the hydraulic telescopic rod axle, and the wheels are mounted on the telescopic rod sections.

[0009] Preferably, a controller is also installed on the vehicle body, and the controller is provided with a wireless communication module for wireless communication with a remote control. The controller is wirelessly controlled by the remote control to open and close the circuits between the battery and the motor and to switch the positive and negative poles, thereby realizing the forward, reverse and stop functions of the vehicle.
[0010] Preferably, a power socket for an external power source is also installed on the vehicle body.
[0011] Preferably, the wheel cooperates with the guide rail, and the wheel is provided with a supporting portion supported on the guide rail and a limiting portion limitedly cooperated with the side surface of the guide rail.
[0012] Preferably, the photovoltaic assembly placement structure includes a vehicle plate and a limiting frame arranged along the circumference of the vehicle plate.
[0013] Preferably, the photovoltaic assembly placement structure also includes a buffer pad arranged on the vehicle panel.
[0014] Preferably, an anti-collision pad is provided on the outer side of the vehicle body.
[0015] The utility model adopts the above technical solution and has the following beneficial effects:
[0016] 1. Place the photovoltaic modules on the vehicle body with the photovoltaic module placement structure, and the wheels can roll on the module rails, which can save effort to drive the vehicle. The wheel spacing of the two wheels can be adjusted through the wheel spacing adjustment structure to match the spacing of the module rails, which can be applied to scenes with different module rail spacings.
[0017] 2. The telescopic rod sections on both sides of the hydraulic telescopic rod shaft can be relatively and synchronously extended and retracted, which can adjust the overall length of the axle, thereby adjusting the wheel spacing of the two wheels so that the wheel spacing matches the assembly guide rail spacing.
[0018] 3. The trolley is automatically driven by an electric motor to achieve semi-automatic transportation. The entire component transportation process does not require human participation in lifting.

[0020] 5. The battery can be charged through the AC / DC power socket with a power cord, and the battery can be charged with AC power or photovoltaic modules. At the same time, the battery can be flexibly and quickly disassembled and charged with AC power.

[0021] 6. Since the wheel is provided with a supporting portion supported on the guide rail and a limiting portion matched with the side of the guide rail, the relative position of the wheel and the guide rail is maintained through the limiting of the limiting portion, ensuring the matching of the wheel and the guide rail.

[0030] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.
[0031] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.
[0032] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the following words indicating orientation or positional relationship, such as "upper", "lower", "longitudinal", "lateral", etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.
[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0034] Referring to the prior art, a number of photovoltaic modules are distributed in a rectangular array and installed on a photovoltaic bracket. The photovoltaic bracket is provided with a module rail that can be set to extend horizontally, and the photovoltaic modules are installed on the module rail. As the size of the modules will change, the longitudinal spacing of the module rails will also change. For a rail-mounted trolley with a fixed wheel spacing, it is impossible to adapt to the changes in the size of the modules and the spacing of the module rails. Figure 1 and Figure 2 As shown, this embodiment provides a photovoltaic module transport trolley with adjustable wheelbase, comprising a vehicle body 4 provided with a photovoltaic module placement structure, an axle 3 installed on the vehicle body, and two wheels 2 installed at both ends of the axle, wherein the axle 3 is provided with a wheelbase adjustment structure for adjusting the wheelbase of the two wheels 2. Referring to the existing trolley structure, two wheel axles are usually arranged side by side in front and back, and a total of four wheels are installed.
[0035] The above technical solution places the photovoltaic modules on a vehicle body with a photovoltaic module placement structure, and the wheels can roll on the module rails, which can drive the vehicle to run with less effort. The wheel spacing of the two wheels can be adjusted through the wheel spacing adjustment structure to match the spacing of the module rails, which can be applied to scenarios with different spacing of the module rails.
[0036] In one embodiment, the axle 3 is a hydraulic telescopic rod axle, the wheel spacing adjustment structure includes telescopic rod sections 31 arranged on both sides of the hydraulic telescopic rod axle axial direction, and the wheels 2 are mounted on the telescopic rod sections 31. The telescopic rod sections on both sides of the hydraulic telescopic rod axle axial direction are relatively synchronously extended and retracted, and the overall length of the axle can be adjusted, thereby adjusting the wheel spacing of the two wheels, so that the wheel spacing matches the assembly guide rail spacing.
[0037] It is understandable that the wheelbase adjustment structure of the axle can also be other structures that can adjust the length of the axle. For example, the axle includes a fixed axis in the middle and telescopic rod sections on both sides. The fixed axis and the telescopic rod sections are telescopically connected by nesting inside and outside, and can be locked by fasteners such as bolts.
[0038] In another embodiment, the trolley is automatically driven by an electric motor, and the vehicle body 4 is also equipped with an electric motor 8 and a reducer 9, the output shaft of the electric motor is connected to the input end of the reducer, and the output end of the reducer is connected to the axle, for example, the output end of the reducer and the axle are connected by gear transmission, belt transmission, etc. The trolley is automatically driven by an electric motor to achieve semi-automatic transportation. The entire component transportation process does not require human participation in lifting and transportation, which releases labor, greatly improves work efficiency, and reduces injuries to joints, lumbar vertebrae, etc. caused by long-term load-bearing and carrying.
[0039] Of course, it is understandable that the car can also use external power, such as an electric winch, to achieve automatic drive.
[0040] Furthermore, the vehicle body 4 is also equipped with a battery 7 for powering the motor 8. The vehicle body 4 is also equipped with a controller 6, which is provided with a wireless communication module for wireless communication with the remote controller. The controller is wirelessly controlled by the remote controller to switch the circuit between the battery and the motor and the positive and negative poles, so as to realize the forward, reverse and stop functions of the vehicle. When the circuit is connected, the motor starts to rotate, and the motor drives the reducer to work. The reducer amplifies the torque, drives the wheels on the wheel shaft to rotate, and the wheels drive the vehicle body and the components on the vehicle body to move together. The length of the hydraulic telescopic rod shaft can also be adjusted by the remote controller to match the wheel spacing with the component guide rail spacing.
[0041] In one embodiment, the vehicle body 4 is also provided with a power socket 5 for an external power source, which is an AC / DC power socket. The battery can be connected to a power cord through the AC / DC power socket, and the battery can be charged with mains electricity or a photovoltaic module. The battery can be flexibly and quickly disassembled and charged with mains electricity. Since local materials can be used, the battery can be directly charged with a photovoltaic module, which is energy-saving and environmentally friendly as a whole.
[0042] The wheel cooperates with the guide rail. In one embodiment, the wheel 2 is provided with a support portion 21 supported on the guide rail and a limit portion 22 limitedly cooperated with the side of the guide rail. The relative position of the wheel and the guide rail is maintained by the limit of the limit portion, ensuring the cooperation between the wheel and the guide rail.
[0043] As an embodiment, the photovoltaic module placement structure includes a vehicle plate and a limiting frame arranged along the circumference of the vehicle plate. The photovoltaic modules can be stacked and placed in a placement space surrounded by the vehicle plate and the limiting frame to prevent the photovoltaic modules from sliding off the vehicle body.
[0044] Furthermore, the photovoltaic module placement structure may also include a buffer pad 11 disposed on the vehicle plate. The buffer pad has a certain thickness, is convenient for taking and placing the module, has an anti-slip function, and can also provide buffering for the photovoltaic module to avoid impact damage.
[0045] Furthermore, the outer side of the vehicle body is provided with an anti-collision pad 10, which is specifically arranged on the outer side of the vehicle plate and the limiting frame. The anti-collision pad is made of flexible material and has the function of anti-collision buffering, thereby preventing the vehicle from being damaged by collision and also preventing the photovoltaic module from being damaged by collision energy.
[0046] It is understandable that the components involved in the photovoltaic module transport cart can all be common components on the market to reduce costs.
[0047] During construction, the truck crane lifts a component onto the component transport cart that is already in place on the component rail. The construction worker presses the forward button on the remote control to run the component transport cart to the end of the component rail, then manually unpacks the box. The construction worker uses the remote control to start the backward creeping mode. As the cart creeps backward, two construction workers lift the component from the cart to the component rail and repeat the above actions to form an assembly line operation.
[0048] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
