Description

Technical Field

[0001] The present application relates to the technical field of lifting equipment, and in particular to a lifting device and an installation system. Background Art

[0002] Purlins are a crucial component of a photovoltaic power station, typically installed horizontally on top of the photovoltaic racks to support and secure the photovoltaic modules. Floating photovoltaics (PV) refers to a photovoltaic power station built on water. Purlins are installed using a floating installation platform constructed near the photovoltaic racks. Currently, two common methods for installing purlins on water are used. One method involves hoisting all purlins onto the floating installation platform, where they are then manually installed onto the photovoltaic racks. However, due to the large number of purlins stacked on the floating installation platform, the platform is prone to capsizing during transportation and installation due to its unstable center of gravity, posing a significant safety hazard. Another method involves transporting the purlins to the vicinity of the floating installation platform using a transport vessel. Operators on the floating installation platform then pick up and install the purlins one by one. This method not only reduces installation efficiency and increases labor costs, but also poses a safety hazard as purlins are easily dropped during transportation.

[0003] In the related art, in order to solve the problems of safety hazards and low installation efficiency, purlins are often transferred from the ground or water surface to the water installation platform through a lifting device. However, since the operators install the purlins on the water installation platform, it is a high-altitude operation on the water. The installation speed of the purlins is affected by many factors (such as water surface waves or wind speed, etc.), resulting in unstable installation speed. The lifting device usually transmits at a uniform speed. The number of purlins transmitted to the water installation platform within a certain period of time by the lifting device is relatively stable, resulting in a mismatch between the consumption rate of the purlins and the transmission speed, which may cause the operators to receive the purlins untimely or wait for too long for the purlins, affecting the installation efficiency and safety.

[0036] An embodiment of the present application discloses a lifting device, which can be applied to an installation system for installing purlins on a photovoltaic bracket to improve installation efficiency and safety.

[0037] In order to facilitate understanding of the structures of the lifting device and the installation system, the lifting device and the installation system will be further described below in conjunction with embodiments and drawings.

[0038] Please also refer to Figures 1 to 3The embodiment of the present application provides a mounting system 200 for mounting a target object 400 at a high altitude on the water surface, such as installing purlins on a photovoltaic bracket 300 of a water photovoltaic power station. The mounting system 200 includes an on-water mounting platform 201 and a lifting device 100. The on-water mounting platform 201 is provided with a mounting frame 202. The lifting device 100 is used to transport the target object 400 to the mounting frame 202. Figure 4 and Figure 5 Specifically, the lifting device 100 includes a frame 10, a conveying mechanism 20 and a storage rack 30. The frame 10 includes a ground end 10a and an overhead end 10b. The conveying mechanism 20 can be movably connected to the frame 10. The conveying mechanism 20 is used to drive the target object 400 (such as purlins) to move between the ground end 10a and the overhead end 10b. The storage rack 30 is located at the overhead end 10b. The storage rack 30 is used to receive the target object 400 that moves to the overhead end 10b.

[0039] The lifting device 100 and the installation system 200 provided in the embodiment of the present application are provided with a conveying mechanism 20 that can be movably connected to the frame 10 to drive the target object 400 to move between the ground end 10a and the high-altitude end 10b of the frame 10, so as to realize the transmission of the purlins from the ground end 10a to the high-altitude end 10b one by one. This not only effectively avoids the situation where the center of gravity of the water installation platform 201 is unstable due to stacking all the purlins on the installation frame 202 of the water installation platform 201, but also realizes the automatic lifting of the purlins, eliminating the step of manual hooking by the operator when installing the purlins, thereby ensuring safety while improving work efficiency. At the same time, by setting up a storage rack 30 at the high-altitude end 10b, the target object 400 can be received by the storage rack 30 when it moves to the high-altitude end 10b with the conveying mechanism 20, so as to realize temporary storage of the target object 400. Therefore, when the operator is on the mounting rack 202 and installing purlins on the photovoltaic bracket 300, on the one hand, when the operator fails to receive the purlins in time, the purlins transported to the high-altitude end 10b can be stored by the storage rack 30, so as to reserve sufficient time for the operator to pick up and place them, so as to avoid the purlins falling or the instability of the water installation platform 201 due to untimely receipt of the purlins. On the other hand, the purlins to be installed can be pre-stored on the storage rack 30 to ensure that the operator can obtain the purlins for installation in time when the operator's installation speed is faster, thereby reducing the operator's waiting time, that is, it can improve the operator's flexibility in taking and placing the purlins, so as to improve the installation efficiency while ensuring safety.

[0040] Optionally, the target object 400 may be a purlin, a steel member, a metal slat or other slat-like structure, which may be configured according to actual needs.

[0041] It can be understood that the ground end 10a refers to an end relatively close to the ground, and the high-altitude end 10b refers to an end relatively far from the ground.

[0042] In some embodiments, the storage rack 30 includes a first guide portion 31 and a second guide portion 32, the first guide portion 31 is directly or indirectly connected to the rack 10 or the conveying mechanism 20, and the second guide portion 32 is connected to the end of the first guide portion 31 away from the conveying mechanism 20, and the first guide portion 31 and the second guide portion 32 are combined to form a temporary storage space 30a with an opening, and the opening is facing the side away from the ground.

[0043] In this way, by providing a temporary storage space 30a with an opening on the storage rack 30, it is possible to facilitate the temporary storage of purlins, improve the stability and reliability of the purlins stored on the storage rack 30, and improve the flexibility of operators in taking and placing purlins, which is beneficial for operators to take, place and install purlins, thereby improving installation efficiency.

[0044] Optionally, the temporary storage space 30a may be in a V-shape, a U-shape, a W-shape, etc., and may be set according to actual needs without limitation.

[0045] Optionally, the first guide portion 31 and the second guide portion 32 are straight strip-like structures, and the first guide portion 31 and the second guide portion 32 are inclined relative to the direction from the ground end 10a to the high-altitude end 10b, so as to facilitate guiding the purlin into the temporary storage space 30a and avoid the purlin leaving the temporary storage space 30a due to inertia.

[0046] Optionally, the lifting device 100 is used to transport the target object 400 to the top of the photovoltaic bracket 300. The top of the photovoltaic bracket 300 is provided with an installation slope 301. The inclination angle of the second guide portion 32 is the same or approximately the same as the inclination angle of the installation slope 301, which is conducive to reducing the distance between the second guide portion 32 and the photovoltaic bracket 300, so as to reduce the installation distance between the purlin and the photovoltaic bracket 300, making it easier for operators to pick up items from the temporary storage space 30a for installation.

[0047] Optionally, the storage rack 30 further includes a horizontally extending fixing portion 33 , one end of the fixing portion 33 is connected to the frame 10 or the conveying mechanism 20 , and the other end of the fixing portion 33 is connected to an end of the first guide portion 31 away from the second guide portion 32 .

[0048] In this way, by providing a horizontally extending fixing portion 33, on the one hand, the purlin can be supported at a position closer to the conveying mechanism 20 to reduce the falling height of the purlin after it leaves the conveying mechanism 20, thereby avoiding damage to the purlin or the storage rack 30 due to high-speed collision. After the purlin leaves the conveying mechanism 20, it is first supported by the fixing portion 33 and then enters the temporary storage space 30a under the action of inertia. On the other hand, it can also guide the target object 400 to move in a direction away from the conveying mechanism 20 to increase the storage space for the target object 400.

[0049] In some embodiments, the lifting device 100 also includes a detection mechanism, which is arranged on the storage rack 30 and is communicatively connected to the conveying mechanism 20. The detection mechanism is used to detect the number of target objects 400 in the storage rack 30 and shut down the conveying mechanism 20 when the number of target objects 400 in the storage rack 30 reaches a preset value.

[0050] In this way, by setting up a detection mechanism to control the number of target objects 400 in the storage rack 30, it is possible to ensure that the number of target objects 400 in the storage rack 30 is sufficient for the operator to pick up the items without interruption, and to avoid equipment failure due to too many target objects 400 in the storage rack 30, or the target objects 400 falling from the storage rack 30 due to the storage rack 30 being fully loaded.

[0051] Optionally, the detection mechanism includes a detection component and a controller, the detection component is electrically connected to the controller, the controller is communicatively connected to the conveying mechanism 20, the detection component is arranged in the temporary storage space 30a, the detection component is used to detect the number of target objects 400 in the temporary storage space 30a and send real-time detection data to the controller, the controller is used to send a stop signal to the conveying mechanism 20 when the number of target objects 400 in the temporary storage space 30a detected by the detection component reaches a preset value, and send a start signal to the conveying mechanism 20 when the number of target objects 400 in the temporary storage space 30a detected by the detection component is lower than a preset value, thereby realizing flexible start and stop control of the conveying mechanism 20 to improve the operation reliability of the lifting device 100.

[0052] Optionally, the detection component may be any one of a light strip sensor, an infrared sensor, a Hall sensor or a counter, etc., and may be specifically configured according to actual needs and is not limited here.

[0053] It is understandable that in other embodiments, the detection mechanism can also be used to detect the weight of items in the storage rack 30, or to detect the storage height in the storage rack 30, etc., to determine the load capacity of the storage rack 30.

[0054] In some embodiments, considering that the purlins usually have a large length and the width of the lifting device 100 is limited, based on this, in order to improve the reliability of purlin lifting, the number of lifting devices 100 can be at least two, and at least two lifting devices 100 are respectively arranged at both ends of the purlin. The first guide portion 31 and the second guide portion 32 are both long plate-like structures, which can help increase the supporting area of ​​the purlin to improve the stability of the purlin on the storage rack 30.

[0055] In some embodiments, the conveying mechanism 20 includes a first driving member 21, a first rotating wheel 22, a second rotating wheel 23, and a conveyor belt 24. The first rotating wheel 22 and the second rotating wheel 23 are respectively rotatably connected to the frame 10, with the first rotating wheel 22 located at the ground end 10a and the second rotating wheel 23 located at the aerial end 10b. The output end of the first driving member 21 is connected to the first rotating wheel 22 or the second rotating wheel 23. The conveyor belt 24 is wrapped around the outer circumference of the first rotating wheel 22 and the second rotating wheel 23 and is rotatably connected to the first rotating wheel 22 and the second rotating wheel 23. The conveyor belt 24 is configured to move relative to the storage rack 30 as the first rotating wheel 22 and the second rotating wheel 23 rotate. This allows the purlins to be lifted from the ground end 10a to the aerial end 10b, thereby transporting the purlins to the mounting rack 202 of the water-based mounting platform 201, thereby facilitating the installation of the purlins on the photovoltaic support 300. Furthermore, the use of the conveyor belt 24 to lift the purlins can also improve the stability of the lifting process.

[0056] Optionally, the conveyor mechanism 20 further includes a plurality of retaining teeth 25, which are spaced apart on the conveyor belt 24 and are used to support the target object 400. This allows for simultaneous transport of multiple purlins, ensuring the operating speed of the conveyor mechanism 20 while also ensuring the number of purlins lifted by the conveyor mechanism 20, thereby facilitating installation efficiency.

[0057] Optionally, the gear 25 includes a supporting portion 251, a limiting portion 252 and a supporting portion 253, the supporting portion 251 is connected to the outer side of the conveyor belt 24, one end of the supporting portion 253 is connected to the conveyor belt 24 and is spaced apart from the supporting portion 251, the other end of the supporting portion 253 is connected to the end of the supporting portion 251 away from the conveyor belt 24, the limiting portion 252 is connected to the end of the supporting portion 251 away from the conveyor belt 24 and extends in a direction away from the supporting portion 253, so that the limiting portion 252, the supporting portion 251 and the conveyor belt 24 enclose a C-shaped supporting space.

[0058] In this way, the purlin is supported by the supporting portion 251 so that the purlin can move with the movement of the conveyor belt 24. At the same time, the limiting portion 252, the supporting portion 251 and the conveyor belt 24 form a C-shaped supporting space, which can be beneficial to the positioning of the purlin and limit the displacement of the purlin on the supporting portion 251 to ensure that the purlin can be safely transported to the storage rack 30. In addition, by providing the supporting portion 253, the structural strength of the supporting portion 251 can also be improved, so as to improve the structural reliability of the retaining teeth 25 and ensure the reliability of the retaining teeth 25 in supporting the purlin.

[0059] It is understandable that in other embodiments, the target object 400 may also be directly fixed to the conveyor belt 24 for lifting by means of bonding, bundling, magnetism, or snap fastening.

[0060] Optionally, as can be seen from the above, the fixed part 33 is connected to the frame 10 or the conveying mechanism 20. When the retaining teeth 25 move with the conveyor belt 24 to the high-altitude end 10b to release the target object 400, the fixed part 33 now needs to avoid the retaining teeth 25 and the conveyor belt 24. Based on this, the fixed part 33 can be a long strip structure, and the fixed part 33 is connected to the end of the frame 10 or the conveyor belt 24, so that it can extend and guide in the direction away from the conveyor belt 24, and can also avoid the movement of the conveyor belt 24 of the retaining teeth 25 to ensure the operational reliability of the lifting device 100.

[0061] In some embodiments, the conveyor belt 24 includes a plurality of sequentially hinged conveyor units, each comprising a support plate and chains disposed at both ends of the support plate. There are two first rotating wheels 22 and two second rotating wheels 23, each disposed at either end of the support plate and corresponding one-to-one with the two chains. The first rotating wheels 22 and the second rotating wheels 23 are gears that mesh with the chains. Thus, the conveyor mechanism 20 employs a chain plate conveyor belt 24, which can improve the carrying capacity of the conveyor mechanism 20, thereby facilitating support of the purlins and ensuring smooth operation.

[0062] It is understandable that in other embodiments, the conveyor belt 24 may also be a chain-type conveyor belt 24, or a conveying structure composed of multiple rotating rollers.

[0063] Optionally, the conveying mechanism 20 also includes a plurality of support rollers 26, which are arranged at intervals inside the conveyor belt 24 and are located between the first rotating wheel 22 and the second rotating wheel 23 along the direction from the ground end 10a to the high-altitude end 10b. The support rollers 26 are rotatably connected to the conveyor belt 24 to support the conveyor belt 24 during its rotation, thereby preventing the conveyor belt 24 from being pressed down by the purlins.

[0064] In some embodiments, the rack 10 includes a conveying bracket 11 and a loading bracket 12. The conveying mechanism 20 is rotatably connected to the conveying bracket 11. The conveying bracket 11 includes a first portion 111 and a second portion 112. The first portion 111 extends from the ground end 10a to the overhead end 10b. The loading bracket 12 and the second portion 112 are respectively located on either side of the first portion 111. The loading bracket 12 is located at the ground end 10a and extends horizontally to the end connected to the first portion 111 near the ground. The second portion 112 is connected to the end of the first portion 111 away from the ground and extends away from the loading bracket 12. This allows the rack 10 to form a Z-shaped structure, which facilitates the horizontal and vertical transportation of purlins. This allows the purlins lifted to the storage rack 30 to be closer to the photovoltaic rack 300, facilitating purlin installation.

[0065] Optionally, the second portion 112 is tilted along the direction from the ground end 10 a to the aerial end 10 b , and the tilt angle of the second portion 112 is the same as the tilt angle of the installation slope 301 .

[0066] In this way, the lifting height of the purlin can be reduced, so that the purlin lifted to the temporary storage space 30a is closer to the photovoltaic bracket 300, so that the operator on the mounting frame 202 can more easily remove the purlin from the temporary storage space 30a and place it on the photovoltaic bracket 300 for fixation, so as to facilitate the installation of the purlin.

[0067] Optionally, the primary function of the first portion 111 is to elevate the purlins, and its inclination angle is typically different from that of the second portion 112. Based on this, the conveying mechanism 20 further includes a third rotating wheel 27, which is meshedly connected to the chain and disposed at the junction of the first portion 111 and the second portion 112. The first rotating wheel 22 is disposed at the end of the first portion 111 closer to the ground, and the second rotating wheel 23 is disposed at the end of the second portion 112 farther from the first portion 111. The fixing portion 33 is rotatably connected to the second rotating wheel 23. Thus, by disposing transmission components at the ends and corners of the conveyor belt 24, the smoothness and reliability of the conveyor belt 24 can be improved.

[0068] In some embodiments, as can be seen from the foregoing, the conveyor mechanism 20 utilizes a chain-net sensor. Based on this, the conveyor support frame includes a first support frame and a second support frame spaced apart from each other. Both the first support frame and the second support frame are provided with limiting slots. The first support frame and the second support frame are respectively located at opposite ends of a support plate. Chains at both ends of the support plate are respectively embedded in the limiting slots and are rotatable relative to the first support frame and the second support frame. This not only supports the conveyor mechanism 20 but also positions the conveyor belt 24, ensuring the operational reliability of the conveyor mechanism 20 and preventing the conveyor belt 24 from falling due to gravity below the first rotating wheel 22, the second rotating wheel 23, and the third rotating wheel 27.

[0069] In some embodiments, as can be seen from the foregoing, the photovoltaic support 300 has an installation slope 301. Based on this, the number of above-water installation platforms 201 can be at least two, and the at least two above-water installation platforms 201 include a first above-water installation platform 2011 and a second above-water installation platform 2012. The first above-water installation platform 2011 and the second above-water installation platform 2012 are respectively disposed at two ends of the photovoltaic support 300, with the first above-water installation platform 2011 disposed at the lower end of the installation slope 301 and the second above-water installation platform 2012 disposed at the higher end of the installation slope 301. The mounting brackets 202 of the first above-water installation platform 2011 and the second above-water installation platform 2012 have different heights to accommodate the heights of the two ends of the installation slope 301. This facilitates the operator in installing the purlins on the photovoltaic support 300.

[0070] Optionally, both ends of the first portion 111 are connected to the first above-water mounting platform 2011 via support columns 40, and the support frame of the first mounting platform is located below the second portion 112. This not only improves the structural stability of the rack 10, but also increases the structural compactness, allowing the transport bracket 11 to be closer to the photovoltaic bracket 300, thereby reducing the transmission distance of the purlins and facilitating the operator's access to the purlins. Furthermore, the rack 10 and the mounting frame 202 use the same above-water mounting platform 201, which facilitates synchronous movement of the rack 10 and the mounting frame 202, thereby saving drive energy.

[0071] It is understandable that in other embodiments, the frame 10 may also be installed on a transport ship, so that the lifting device 100 and the mounting frame 202 are supported on the water through different platforms respectively, so as to improve safety.

[0072] Optionally, the second installation platform is provided with a plurality of installation frames 202 of different heights, so as to facilitate installation of the purlins at different positions of the photovoltaic support 300 .

[0073] Optionally, the first mounting platform and the second mounting platform are composed of a pontoon and a steel plate, and the pontoon is made of polyurethane material, thereby increasing the buoyancy of the first mounting platform and the second mounting platform, thereby facilitating improving the stability of the first mounting platform and the second mounting platform in water.

[0074] Optionally, the mounting frame 202 is formed by welding a plurality of steel pipes, thereby increasing the load-bearing capacity of the mounting frame 202 and improving the structural reliability of the mounting frame 202 .

[0075] Optionally, the installation system 200 further includes a second driving member, which is installed on the water installation platform 201 and is used to drive the water installation platform 201 to move close to the photovoltaic bracket 300 to facilitate the installation of purlins.

[0076] In some embodiments, the loading bracket 12 extends from one end connected to the first portion 111 in a direction away from the photovoltaic bracket 300 to a transport ship equipped with purlins, thereby facilitating the transfer of purlins to the loading bracket 12 for loading the conveying mechanism 20 .

[0077] Optionally, the loading bracket 12 is a hollow frame structure, so that the retaining teeth 25 can take away the purlin when passing through the connection between the first part 111 and the loading bracket 12, so as to achieve the lifting of the purlin.

[0078] Optionally, a limiting baffle is provided at one end of the loading bracket 12 away from the first portion 111 , thereby limiting the purlin placed on the loading bracket 12 and preventing the purlin from falling from the loading bracket 12 .

[0079] Optionally, the conveying mechanism 20 further includes a plurality of feeding rollers 28, which are spaced apart on the feeding bracket 12. The purlins are transferred to the end of the feeding mechanism close to the first portion 111 by the feeding rollers 28, so that the retaining teeth 25 push the purlins to move along with the conveyor belt 24 and lift them.

[0080] For ease of reading and understanding, the working process of the installation system 200 is described below:

[0081] First, the water installation platform 201 and the lifting device 100 are driven or moved to a position close to the photovoltaic bracket 300, and the transport ship loaded with purlins is driven to the side of the loading bracket 12. The distance between the transport ship and the loading bracket 12 is adjusted and then the ship is stopped. The positions of the retaining teeth 25 of the two lifting devices 100 are checked to ensure consistency. The two conveying mechanisms 20 are activated simultaneously. The operator places the purlin on the loading roller 28. As the loading roller 28 rotates, the purlin is transferred to the ground-facing end of the first portion 111. At this point, as the conveyor belt 24 rotates, the retaining teeth 25 of the two lifting devices 100 lift the purlin. When the purlin reaches the high-altitude end 10b of the second portion 112, it moves downward along with the retaining teeth 25 until it falls to the fixed portion 33 of the storage rack 30. It then moves into the temporary storage space 30a by inertia. The operator on the mounting rack 202 removes the purlin from the temporary storage space 30a and installs it on the photovoltaic rack 300. When the number of purlins in the temporary storage area reaches a preset value, the detection mechanism controls the conveying mechanism 20 to stop and wait.

[0082] After the purlins on the current photovoltaic support 300 are installed, the installation system 200 moves to the next photovoltaic support 300 to be installed to install the purlins on the next photovoltaic support 300 .

[0083] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
