Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting tools, and specifically relates to a hoisting tool for photovoltaic installation. Background Technique

[0002] Photovoltaic, that is, a photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy source of the photovoltaic power generation system is the inexhaustible and renewable solar energy, which is a clean, safe and renewable energy. The photovoltaic power generation process does not pollute the environment or damage the ecology. The photovoltaic power generation system is divided into an independent photovoltaic system and a grid-connected photovoltaic system. The photovoltaic power generation system is composed of equipment such as a solar cell array, a battery pack, a charge and discharge controller, an inverter, an AC distribution cabinet, and a solar tracking control system. In the photovoltaic panel installation project, hoisting equipment is usually required to hoist the photovoltaic panels.

[0003] For example, a photovoltaic installation hoist with the publication number CN219585634U includes a hoisting box and clamping blocks. The clamping blocks are clamped on the photovoltaic power generation panel. The clamping blocks are in an L-shaped structure and there are four in total. The four clamping blocks are respectively located at the four corners of the photovoltaic power generation panel, and connecting blocks are rotatably connected to the top surfaces. Clamping plates are arranged in the four clamping blocks. The clamping plates are used to fix the clamping blocks on the photovoltaic power generation panel. A perforated belt is connected between the connecting blocks on the diagonal of the photovoltaic power generation panel. The intersection of the two perforated belts is connected with a hoisting box. By setting four clamping blocks in an L-shaped structure to clamp the four corners of the photovoltaic power generation panel, and then connecting the clamping blocks diagonally through two perforated belts, and reserving the required length of the perforated belt according to the actual required inclination angle of the photovoltaic power generation panel, the photovoltaic power generation panel can be easily hoisted, improving the hoisting and installation efficiency of the photovoltaic power generation panel;

[0004] However, in daily use, we found that after the photovoltaic panel is hoisted, it needs to be tilted at a certain angle with the ground for installation, but this hoist cannot adjust the angle of the photovoltaic panel after hoisting. To solve the above problems, a hoisting tool for photovoltaic installation is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hoisting tool for photovoltaic installation to solve the above problems, including:

[0006] A chassis, one side of the upper end of which is hinged with a rotating plate, and one side of the lower end of the chassis is hinged with an electric telescopic rod, and the output shaft of the electric telescopic rod is hinged to the lower wall of the rotating plate;

[0007] A slide rail, which is fixedly installed on both sides of the upper surface of the rotating plate. Both outer walls of the two slide rails are slidably connected with sliders. A connecting rod is fixedly installed between the two sliders. Clamping blocks are slidably connected to both sides of the upper surface of the connecting rod.

[0008] Through the above technical solution, when it is necessary to hoist a photovoltaic panel, first adjust the rotating plate to be parallel to the ground, place the photovoltaic panel between the two clamping blocks, and clamp and fix the photovoltaic panel by pulling the two clamping blocks. After the fixing is completed, connect the chassis to the crane, and hoist the chassis to the photovoltaic panel mounting rack by the crane. At this time, the electric telescopic rod extends to adjust the angle of the rotating plate to the same angle as the photovoltaic panel mounting rack. After the adjustment is completed, push the connecting rod to move it outward along the slide rail, and move the photovoltaic panel to the photovoltaic mounting rack, so that the hoisting tool has the function of adjusting the angle.

[0009] In a preferred embodiment, connecting beams are welded to both the front and rear sides of the chassis, and a hoisting ring is welded to the middle of the outer wall of the connecting beam.

[0010] Through the above technical solution, it is convenient to connect the chassis to the crane by setting the hoisting ring.

[0011] In a preferred embodiment, locking pins are threadedly connected to the middle of both the slider and the clamping block.

[0012] Through the above technical solution, during the hoisting process of the photovoltaic panel, the slider and the clamping block are fixed by fixing the locking pins to prevent the photovoltaic panel from moving during the hoisting process. When installing the photovoltaic panel, the locking pin at the slider is removed so that the slider can move along the slide rail, thus facilitating the unloading of the photovoltaic panel from the hoisting tool.

[0013] In a preferred embodiment, a push rod is welded to the middle of the outer wall of one side of the connecting rod.

[0014] Through the above technical solution, it is convenient to push the connecting rod outward by setting the push rod.

[0015] In a preferred embodiment, anti-slip pads are fixedly installed at the four corners of the bottom of the chassis.

[0016] Through the above technical solution, when loading the photovoltaic panel, the chassis is kept stationary by the anti-slip pads.

[0017] In a preferred embodiment, the electric telescopic rod is controlled by a PLC.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is: The present utility model provides a hoisting tool for photovoltaic installation.

[0019] When the photovoltaic panel needs to be hoisted, first adjust the rotating plate to be parallel to the ground, place the photovoltaic panel between two clamping blocks, and clamp and fix the photovoltaic panel by pulling the two clamping blocks. After the fixing is completed, connect the chassis to the crane, and lift the chassis to the photovoltaic panel mounting rack by the crane. At this time, the electric telescopic rod extends to adjust the angle of the rotating plate to the same angle as the photovoltaic panel mounting rack. After the adjustment is completed, push the connecting rod to move it outward along the slide rail, and move the photovoltaic panel to the photovoltaic mounting rack, so that the lifting tool has the function of adjusting the angle.
