Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel transportation, in particular to a lift suitable for transporting rooftop photovoltaic panels. Background Art

[0002] With the growing global demand for renewable energy, solar photovoltaic power generation has garnered widespread attention as a clean, sustainable energy solution. When installing rooftop photovoltaic systems, safely and efficiently transporting equipment and materials, including photovoltaic panels, to the rooftop becomes a crucial step in the construction process. As core components of photovoltaic power generation systems, photovoltaic panels are not only expensive but also relatively fragile, susceptible to damage during handling. Furthermore, given their large size and weight, ensuring the safe transportation of photovoltaic panels has become a key factor in improving installation efficiency and ensuring project quality.

[0003] However, in actual operation, due to site conditions (such as narrow space layout, height restrictions of surrounding buildings, etc.), it is sometimes impossible to use traditional large-scale machinery such as cranes for lifting operations. In this case, it is often necessary to rely on manpower to carry through stairs or use simple tools such as ropes to complete the lifting of photovoltaic panels. However, both methods have obvious shortcomings: on the one hand, manual handling is time-consuming and labor-intensive, greatly reducing work efficiency; on the other hand, whether it is direct hand-carrying or lifting with ropes, it is difficult to completely avoid the risk of damage caused by collisions due to improper operation, and it may even lead to safety accidents, posing a threat to the lives of workers. For this reason, a lift suitable for transporting rooftop photovoltaic panels is proposed. Utility Model Content

[0007] As a further solution of the present invention: an upper limiter and a lower limiter for limiting the moving range of the sub-frame are respectively installed on the main frame, and the sub-frame is located between the upper limiter and the lower limiter.

[0008] As a further solution of the present invention: a support frame for holding the photovoltaic panel is provided on the sub-frame, and a layer of rubber is laid on the contact surface between the support frame and the photovoltaic panel.

[0009] As a further solution of the present invention: the limiting mechanism is specifically a fixing rope, and the end of the fixing rope is connected to the surface of the sub-frame.

[0010] As a further solution of the present invention: the limiting mechanism includes a limiting assembly, the limiting assembly includes a slide groove opened on the sub-frame, a limiting column is vertically installed inside the slide groove, the outer peripheral surface of the limiting column is provided with a clamping block adapted to the slide groove, and the outer peripheral surface of the limiting column is provided with a compression spring with two ends respectively connected to the clamping block and the slide groove.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 In an embodiment of the utility model, a lift suitable for transporting rooftop photovoltaic panels includes a main frame 1 and a sub-frame 2. A driving mechanism for controlling its ascent or descent is installed on the sub-frame 2. A photovoltaic panel 10 is also provided on the sub-frame 2. The photovoltaic panel 10 is fixed to the sub-frame 2 through a limiting mechanism. A support frame for holding the photovoltaic panel 10 is provided on the sub-frame 2. A layer of rubber is laid on the contact surface between the support frame and the photovoltaic panel 10. The setting of the rubber can better protect the frame of the photovoltaic panel 10. The driving mechanism includes a fixed pulley 5 installed on the upper end of the main frame 1 and a movable pulley 9 installed on the sub-frame 2 and in contact with the main frame 1. The outer circumference of the fixed pulley 5 is provided with a steel wire rope 6.

[0021] Specifically, in order to ensure the stability of the overall frame, the angle between the main frame 1 and the ground must be maintained between 45° and 60°. Secondly, the main frame 1 and the sub-frame 2 are movably connected, and under the action of the movable pulley 9, on the one hand, the sub-frame 2 is limited to be able to move up and down along the side of the main frame 1, and on the other hand, the friction between the main frame 1 and the sub-frame 2 is reduced, so that the sub-frame 2 is more stable during the lifting process. Secondly, the limiting mechanism is specifically a fixed rope 11, and the end of the fixed rope 11 is connected to the surface of the sub-frame 2. The fixed rope 11 is used to fix the photovoltaic panel 10 on the sub-frame 2, which can prevent the photovoltaic panel 10 from overturning during the rising process. At the same time, the fixed pulley 5 is fixed to the upper end of the main frame 1 and its position needs to be higher than the roof. The steel wire rope 6 is connected to the power structure at one end to drive the steel wire rope 6 connected to the sub-frame 2 at the other end to rise, so that the photovoltaic panel 10 on the ground rises to the roof for use by people on the roof.

When the sub-frame 2 is at the lower end and contacts the lower limiter 8, it is convenient for the staff to assemble the photovoltaic panel 10 on the sub-frame 2, and the upper limiter 7 is provided at the upper end of the main frame 1. When the upper end of the sub-frame 2 contacts the upper limiter 7, it is also convenient for the staff to remove the photovoltaic panel 10 from the sub-frame 2.
