Description

Technical Field

[0001] This utility model relates to the field of photovoltaic construction, specifically to a photovoltaic construction hoisting device. Background Technology

[0002] As the global energy structure shifts towards clean energy, photovoltaic (PV) power generation, as an important form of renewable energy utilization, has seen its installed capacity grow rapidly, and the scale of PV power plant construction is also expanding. During the construction of PV power plants, the hoisting and installation of PV modules (such as PV panels) is one of the core aspects, directly affecting construction efficiency, project quality, and construction safety.

[0003] Although existing photovoltaic hoisting devices have simple clamping structures, they mostly use manual bolt locking or spring pre-tightening methods, which makes it difficult to adjust the clamping force.

[0004] Therefore, it is very necessary to provide a photovoltaic construction hoisting device to solve the above-mentioned technical problems. Utility Model Content

[0005] Based on the above description, this utility model provides a photovoltaic construction hoisting device to solve the problem that although the existing photovoltaic hoisting devices have simple clamping structures, they mostly use manual bolt locking or spring pre-tightening methods, which makes it difficult to adjust the clamping force.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A photovoltaic construction hoisting device includes a hook and a corner fixing component connected to the hook. The corner fixing component includes a fixed base frame and a pressing frame rotatably connected to the fixed base frame. The pressing frame is used to cooperate with the fixed base frame to fix it on the photovoltaic construction fixing block. The corner fixing component also includes a hydraulic rod with one end rotatably connected to the fixed base frame and the other end rotatably connected to the pressing frame. The hydraulic rod is used to drive the pressing frame to rotate.

[0007] Furthermore, a lifting rope is connected between the hook and the corner fixing member.

[0008] Furthermore, a pressing block is connected to one end of the pressing frame.

[0009] Furthermore, the pressing block is made of rubber.

[0013] The corner fixing components, through the cooperative design of the fixed base frame and the pressing frame, can be tightly and securely fixed to the photovoltaic construction fixing block. During the hoisting process, this stable fixing method effectively avoids photovoltaic module slippage accidents caused by shaking or displacement, greatly reducing the safety threats to construction personnel and the surrounding environment during high-altitude operations, and providing reliable safety assurance for the entire photovoltaic construction process. This solves the problem that while existing photovoltaic hoisting devices have simple clamping structures, they mostly use manual bolt locking or spring pre-tensioning methods, which makes it difficult to adjust the clamping force.

[0020] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0022] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "below" of the other element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0023] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0024] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.
