[0002] Currently, the installation of photovoltaic (PV) brackets and modules in the construction of PV power plants typically relies on large lifting equipment, such as truck cranes. While this method can accomplish the lifting task, large equipment often struggles to access and operate in complex terrain (such as mountains and hills) or space-constrained locations, resulting in high construction costs, poor flexibility, and low efficiency. Furthermore, traditional lifting methods are inconvenient to operate and lack precision when precise lateral adjustments and positioning of the brackets or modules are required, affecting the overall installation quality and speed. Therefore, there is an urgent need for a photovoltaic bracket installation auxiliary device that is simple in structure, easy to move, flexible in operation, and capable of precise positioning. Summary of the Invention

Through the coordinated operation of a winch, traction rope and pulley block, and by integrating a structure of laterally movable fixed pulleys and movable pulleys, it can effectively complete the hoisting and precise positioning of photovoltaic brackets in complex environments. It has the advantages of stable structure, simple operation and accurate positioning.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a photovoltaic bracket installation device, including a bracket, the bracket being composed of a vertical pole and a cantilever rod located at the upper end of the vertical pole, the lower end of the vertical pole being fixed to a base plate; One end of the cantilever is provided with a rope end fixing component, and one end of the traction rope is fixed on the rope end fixing component.

A movable pulley 6 and a transverse fixed pulley 8 are provided below the cantilever 102. The traction rope 2 passes through the movable pulley 6 and the transverse fixed pulley 8 in sequence and connects with the winch 5 provided on the base plate 3.

[0021] In a preferred embodiment, a reinforcing brace 103 is provided at the corner position of the upright 101 and the cantilever 102, and a fixed guide wheel 7 is fixedly provided on the reinforcing brace 103, and the traction rope 2 is also provided through the fixed guide wheel 7.

[0022] In a preferred embodiment, the base plate 3 is fixed by base plate fixing piles 301 inserted into the ground.

[0023] In a preferred embodiment, the cantilever rod 102 is provided with a slot 10, and a transverse fixed pulley support 9 is provided in the slot 10. The transverse fixed pulley 8 is installed at the lower end of the transverse fixed pulley support 9. The cantilever rod 102 has a motor 11 at one end of its top surface and a vertical plate 12 at the other end. The motor 11 has a horizontal lead screw 13 on its drive shaft. One end of the lead screw 13 is movably mounted on the vertical plate 12. The transverse fixed pulley support 9 has a threaded hole 902 on the part that passes through the slot 10. The lead screw 13 passes through the threaded hole 902.

[0024] In a preferred embodiment, T-shaped grooves 1001 are provided on both sides of the slot 10, and limiting protrusions 901 are provided on both sides of the portion of the transverse fixed pulley support 9 passing through the slot 10. The limiting protrusions 901 are disposed in the T-shaped grooves 1001.

[0025] In a preferred embodiment, the slot 10 is further provided with a movable pulley bracket 14, and rollers 16 are provided on both sides of the upper part of the movable pulley bracket 14. The rollers 16 are disposed in the T-shaped slide groove 1001. In a preferred embodiment, the lower part of the movable pulley bracket 14 is provided with a vertical groove 141, and a slider 15 is provided in the vertical groove 141, with the movable pulley 6 disposed on the slider 15.

[0026] In a preferred embodiment, the sidewall of the vertical groove 141 is provided with a guide groove 142, and the slider 15 is provided with protrusions on both sides that match the guide groove 142.

[0027] In a preferred embodiment, the inner wall of the movable pulley 6 is provided with an annular groove 602, and a sliding member 601 is provided in the annular groove 602. The traction rope 2 passes through the sliding member 601 and the axle of the movable pulley 6. A lifting hook 17 is connected to the outer wall of the sliding member 601 by a lifting rope, and a hook locking member 171 is provided on the lifting hook 17.

[0028] In a preferred embodiment, a counterweight 302 is also provided on the base plate 3.

[0029] The photovoltaic bracket installation device disclosed in this utility model is used for photovoltaic module 19 installation operations: The device is transported to the designated installation point, and the base plate 3 is securely fixed to the ground using the base plate fixing pile 301 and the counterweight block 302. The motor 11 is started, driving the lead screw 13 to rotate, thereby moving the transverse fixed pulley support 9 and the entire associated movable pulley assembly to a position above the cantilever rod 102 for easy hoisting.

[0030] Hook the lifting hook 17 onto the photovoltaic bracket or module to be installed. Start the winch 5 to rotate forward and tighten the traction rope 2. The tension of the traction rope 2 is transmitted sequentially through the horizontal fixed pulley 8 and the fixed guide wheel 7 to the movable pulley 6, causing the movable pulley 6 to rise, thereby vertically lifting the heavy object off the ground. Since the sliding component 601 can slide freely on the movable pulley 6, it can automatically adjust its position to ensure that the lifting hook 17 and the heavy object remain vertical during the lifting process, avoiding rotation and swaying.

[0031] Lateral Precision Positioning: After the load is lifted to the required height, motor 11 is restarted. Motor 11 drives the lateral fixed pulley support 9 to move laterally along the slot 10 via lead screw 13. Since the traction rope 2 passes around the lateral fixed pulley 8, the movement of the lateral fixed pulley 8 directly changes the direction and length of its downstream rope segment, thereby driving the lower movable pulley 6, lifting hook 17, and load to move laterally precisely until the load is accurately moved directly above the installation point.

[0032] Final positioning and resetting: Control the winch 5 to slowly reverse and release the traction rope 2, allowing the photovoltaic module 19 to descend smoothly onto the module mounting column 18, completing the precise positioning and installation. After installation, remove the lifting hook 17, and control the winch 5 and motor 11 to reset the movable pulley 6 and the transverse fixed pulley support 9 to their initial or next working position, preparing for the next lifting operation.

[0033] Example 2: For distributed photovoltaic projects that require frequent relocation and multi-point operations, further structural modifications are made based on Example 1: The base plate 3 of the bracket 1 is fixed to the frame of an engineering truck or large trailer via a rotatable slewing bearing. A small diesel generator is integrated on the frame, or the vehicle's power take-off (PTO) system is used directly to provide power to the winch 5 and the motor 11. The upright 101 can adopt a multi-section sleeve-type hydraulic cylinder structure, driven by the vehicle's own hydraulic system for lifting; the cantilever 102 can also be designed to be hydraulically foldable to reduce the overall height and length during transportation to meet road driving regulations.

[0034] Example 3: For large-scale photovoltaic power plants, in scenarios involving long-distance, sequential hoisting operations between rows of photovoltaic supports: The base plate 3 is fixedly installed on top of a portal frame, which has rollers installed on both sides of its bottom, allowing it to move on a track pre-laid between two rows of photovoltaic foundations. The winch 5 and control system are integrated into the portal frame. A servo motor drive system can be configured for the track to achieve precise positioning of the portal frame on the track.

[0035] The device moves slowly along the track, stopping after each support position. Then, the hoisting and traversing system is activated to lift the photovoltaic module 19 and precisely install it onto the module mounting column 18. After completion, the device moves along the track to the next workstation and repeats the process. This embodiment achieves a streamlined and highly automated installation process, making it particularly suitable for large-scale ground-mounted photovoltaic power plants in flat terrain, significantly improving the efficiency and linearity of large-scale installations.

[0036] Example 4: For the hoisting of long-sized photovoltaic modules (such as double-glass modules) or large combined support structures, it is required to keep them absolutely horizontal during the hoisting process to prevent bending damage.

[0037] Two independent sets of lateral fixed pulley supports 9, movable pulley brackets 14, movable pulleys 6, and lifting hooks 17 are installed in parallel on the cantilever 102. These two systems can be driven by two motors 11 and two winches 5 respectively, or by mechanical linkage (such as two opposing threads on a single lead screw 13) and an electrical synchronization control system to ensure that the two lifting points can achieve synchronous lifting and synchronous lateral movement.

[0038] Attach the two lifting hooks 17 to the lifting points at both ends of the long object. Activate the synchronous control mode, and the winch 5 and motor 11 operate synchronously to ensure that the object remains horizontal throughout the lifting, lateral movement, and descent process. This effectively avoids component cracks or bracket deformation that may occur with single-point lifting, greatly ensuring installation quality, and is particularly suitable for installing sensitive materials with strict requirements for bending resistance.

[0039] Example 5: For small projects or scenarios with limited budgets, the following solutions can be adopted to further reduce costs and simplify the structure: The motor 11 and lead screw 13 structures are eliminated. The transverse fixed pulley support 9 is directly fixed to different positions of the slot 10 of the cantilever 102 via a manual locking mechanism (such as a handle bolt). The winch 5 is replaced with a manual winch. All structures are made of aluminum alloy or high-strength composite materials to reduce weight.

[0040] Operating principle: Before installation, workers manually adjust the position of the transverse fixed pulley support 9 on the slot 10 according to the estimated installation location, and fix it with a manual locking mechanism. Then, the lifting and lowering operation is carried out by a manual winch. Although the transverse positioning is segmented and discrete, unlike the continuous operation of a motor drive, the installation accuracy requirements can still be basically met through slight swaying or manual fine-tuning during the lifting process. This embodiment greatly reduces manufacturing costs and dependence on power, making it very suitable for small-scale operations in areas without electricity or in remote areas.
