Description

Technical Field

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

[0002] Photovoltaic construction hoisting equipment is a type of mechanical equipment specifically used for hoisting and transporting photovoltaic modules, brackets, and other equipment during the construction of photovoltaic power plants. It can lift these devices from the ground or transport vehicles and accurately place them in the designated installation position to improve construction efficiency, reduce manual labor intensity, and ensure the safety and stability of the equipment during the hoisting process.

[0003] There are some problems with existing ordinary photovoltaic panel hoisting mechanisms during the installation of photovoltaic panels: First, only one set of photovoltaic panels can be hoisted at a time, which results in low hoisting efficiency. Second, in order to prevent the photovoltaic panels from falling during the hoisting process, four or more hooks are usually used to fix the edges of the photovoltaic panels. After the photovoltaic panels are hoisted to the roof, the workers need to disassemble these hooks one by one, which is not only time-consuming but also labor-intensive.

[0004] To address these issues, some technologies use two clamps to secure multiple photovoltaic panels while maintaining a certain distance between them. However, when removing the panels, multiple panels may loosen simultaneously. If the clamps are tilted, the panels may slip out of the clamps, potentially causing economic losses and safety accidents. Therefore, a hoisting device for photovoltaic construction is proposed to address these problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Please see Figure 1-8 This utility model provides a technical solution:

[0032] A hoisting device for photovoltaic construction includes a hoisting component 1, a photovoltaic panel body 2, a first clamping component 3, and a positioning component 4. The hoisting component 1 is rotatably connected to the first clamping component 3 and the second clamping component 5. The photovoltaic panel body 2 is installed between the first clamping component 3 and the positioning component 4. The positioning component 4 is fixedly connected to the front end of the hoisting component 1. The first clamping component 3 includes a shaft column 31. A ball bearing 32, a gear 33, and a rubber wheel 34 are fixedly connected to the outer side of the shaft column 31. A clearance groove 35 is opened on the inner side of the rubber wheel 34. The positioning component 4 includes a positioning shell 41. A threaded rod 43 is rotatably connected to the inner side of the positioning shell 41 through a bearing. A rotating handle 42 is fixedly connected to the right side of the threaded rod 43. An internal threaded plate 45 is spirally connected to the outer side of the threaded rod 43. A toothed groove 46 is opened at one end of the internal threaded plate 45. Track grooves 44 are opened at both the upper and lower ends of the positioning shell 41. The inner side of the hoisting component 1 is rotatably connected to the outer side of the shaft column 31 through the ball bearing 32. The front end of the hoisting component 1 is fixedly connected to the rear end of the positioning shell 41.

[0033] As a further implementation of this solution, the hoisting assembly 1 includes a frame 11, with a steel wire rope 12 fixedly connected to the top of the frame 11, a rope fixing block 13 fixedly connected to the top of the steel wire rope 12, and a lifting ring 14 fixedly connected to the top of the rope fixing block 13. Limiting pivot holes 15 are provided at both the front and rear ends of the frame 11, which can engage the lifting ring 14 with the hook of the crane, and then lift the entire device through the lifting ring 14.

[0034] As a further implementation of this solution, the inner side of the frame 11 is hollow, and the opening shape of the limiting rotating hole 15 is cylindrical. The limiting rotating hole 15 on the inner side of the frame 11 is fixed to the outer side of the ball bearing 32. The front end of the shaft 31 protrudes from the front end of the frame 11, which facilitates the shaft 31 to rotate and connect inside the frame 11, thereby limiting the rotation of the shaft 31 and reducing the friction when the photovoltaic panel body 2 is loaded.

[0035] As a further implementation of this solution, the structure of the first clamping component 3 is the same as that of the second clamping component 5. The shaft column 31 is cylindrical, and two ball bearings 32 are fixed on the outside of the shaft column 31. Multiple rubber wheels 34 are fixed on the outside of the shaft column 31. The photovoltaic panel body 2 is clamped by the cooperation of the first clamping component 3 and the second clamping component 5.

[0036] As a further implementation of this solution, the front end of the shaft column 31 is located inside the positioning shell 41. The outer side of the gear 33 meshes with the toothed groove 46 of the internal thread plate 45. The number of gears 33 is the same as the number of shaft columns 31. The clearance groove 35 penetrates the outside of the rubber wheel 34. The outer side of the rubber wheel 34 is attached to one end of the photovoltaic panel body 2. The shape of the rubber wheel 34 is a slotted cylinder. The inner side of the positioning shell 41 is hollow. The front and rear ends of the positioning shell 41 are through structures. The top and bottom ends of the internal thread plate 45 are fixedly connected to rails. The threaded plate 45 is slidably connected to the inner side of the track groove 44 opened in the positioning shell 41. The inner side of the positioning shell 41 near the threaded rod 43 has a shaft hole. A bearing is installed inside the shaft hole of the positioning shell 41. The positioning component 4 limits the rotation of the gear 33 and the shaft column 31, thereby preventing the photovoltaic panel body 2 from falling out of the first clamping component 3 and the second clamping component 5, ensuring the stability of the photovoltaic panel body 2 during hoisting. At the same time, the flexible limiting between the positioning component 4 and the first clamping component 3 facilitates the unloading of the photovoltaic panel body 2 later.

[0037] Workflow: When fixing the photovoltaic panel body 2, the photovoltaic panel body 2 is placed between the rubber wheel 34 on the second clamping assembly 5 and the rubber wheel 34 on the first clamping assembly 3. When the photovoltaic panel body 2 contacts the rubber wheel 34, the rubber wheel 34 deforms. The gap groove 35 provides space for the rubber wheel 34 to move when it deforms. At the same time, the gap groove 35 can increase the friction between the rubber wheel 34 and the photovoltaic panel body 2, thereby adapting to the thickness of the photovoltaic panel body 2. When the rubber wheel 34 and... After the photovoltaic panel body 2 makes contact, the rubber wheel 34 drives the shaft 31 to rotate. The shaft 31 is rotatably connected to the inside of the limiting rotating hole 15 opened in the frame 11 through the ball bearing 32. The setting of the limiting rotating hole 15 and the ball bearing 32 can reduce the friction when the photovoltaic panel body 2 is loaded, and at the same time, it can limit the rotation of the shaft 31. After the photovoltaic panel body 2 is installed, the rotating handle 42 drives the threaded rod 43 to rotate. The threaded rod 43 is rotatably connected to the outside of the positioning shell 41 through the bearing. When the threaded rod 43 rotates... Simultaneously, multiple internally threaded plates 45 connected by an outer spiral move toward the gear 33, causing the toothed grooves 46 on the internally threaded plates 45 to mesh with the outer side of the gear 33. At the same time, the internally threaded plates 45 slide within the grooves 44 of the positioning housing 41, limiting the movement direction of the internally threaded plates 45. Under the action of the internally threaded plates 45 meshing with the gear 33, the gear 33 and the shaft 31 will not rotate. Simultaneously, the friction between the rubber wheel 34 and the photovoltaic panel body 2 prevents the photovoltaic panel body 2 from slipping. The above principle is applied to the installation of other photovoltaic panel bodies 2. After installation, the lifting ring 14 is engaged with the crane hook, and the whole assembly is lifted by the lifting ring 14, the fixing rope block 13 and the wire rope 12. When unloading the photovoltaic panel body 2, the rotating handle 42 is rotated one by one to make the designated internal thread plate 45 engage with the gear 33. At this time, the photovoltaic panel body 2 is removed one by one. This will prevent the photovoltaic panel body 2 from automatically slipping down and ensure the safety of unloading the photovoltaic panel body 2, avoiding economic losses and safety accidents.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
