Description

Technical Field

[0001] This application relates to the field of hoisting technology, specifically to a hoisting device for aluminum alloy profiles. Background Technology

[0002] In modern industrial manufacturing and other fields, lightweight aluminum alloy profiles have been widely used due to their excellent properties such as low density, high strength, and corrosion resistance. Lifting is an essential step in the production, transportation, and installation of aluminum alloy profiles. However, for longer lightweight aluminum alloy profiles, due to their structural characteristics, the middle section is prone to bending and deformation during lifting due to gravity and improper lifting methods.

[0003] Once aluminum alloy profiles are bent and deformed, it will not only seriously affect the appearance quality of the profiles, but also change their mechanical properties, leading to a decrease in the strength, stiffness and other indicators of the profiles, which in turn affects subsequent use and increases production and maintenance costs. At present, common hoisting equipment and methods on the market often focus on improving hoisting efficiency, and lack targeted solutions for preventing deformation of lightweight aluminum alloy profiles during hoisting, making it difficult to meet actual production needs. Summary of the Invention

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1-6 As shown, this application provides a technical solution: an aluminum alloy profile hoisting device, including a hoisting body 1, the hoisting body 1 having a lifting end 11 that can move up and down, a connecting platform 2 hinged to the bottom of the lifting end 11, a first steel wire rope 3 and a second steel wire rope 31 of adjustable length installed on the connecting platform 2, the first steel wire rope 3 and the second steel wire rope 31 being used to fix the two ends of the profile 6 respectively, a bearing hoisting member 4 for holding the middle part of the profile 6 is installed directly below the connecting platform 2, a pressure plate 5 is slidably connected to the bearing hoisting member 4, and the pressure plate 5 presses on the upper surface of the middle part of the profile 6.

[0029] The supporting lifting component 4 includes a flexible support plate 41 and a first lifting rope 401, a second lifting rope 402, a third lifting rope 403 and a fourth lifting rope 404 connected to the connecting platform 2. The support plate 41 is square. The bottom ends of the first lifting rope 401, the second lifting rope 402, the third lifting rope 403 and the fourth lifting rope 404 are respectively fixedly connected to the four corners of the support plate 41.

[0030] The pressure plate 5 has a main body 51, on which a first through hole 511, a second through hole 512, a third through hole 513 and a fourth through hole 514 are provided. The first through hole 511, the second through hole 512, the third through hole 513 and the fourth through hole 514 are distributed at the four corners of the main body 51.

[0031] The first suspension rope 401 passes through the first hole 511, the second suspension rope 402 passes through the second hole 512, the third suspension rope 403 passes through the third hole 513, and the fourth suspension rope 404 passes through the fourth hole 514.

[0032] The pressure plate 5 has two locking blocks 52, which are elastically telescopically connected to both sides of the main body 51. Two extension rods 521 are provided on one side of the locking block 52. The end of the extension rod 521 away from the locking block 52 is a supporting part 523. The supporting part 523 on one of the locking blocks 52 supports the first suspension rope 401 in the first through hole 511 and the third suspension rope 403 in the third through hole 513. The supporting part 523 on the other locking block 52 supports the second suspension rope 402 in the second through hole 512 and the fourth suspension rope 404 in the fourth through hole 514.

[0033] Each extension rod 521 is fitted with a spring 53. A corresponding receiving cavity 510 is formed on the extension rod 521 at the location of the spring 53. The extension rod 521 has a limiting part 522. The extension rod 521 passes through the receiving cavity 510, so that the limiting part 522 is located within the receiving cavity 510. One end of the spring 53 abuts against the limiting part 522, and the other end abuts against the bottom of the receiving cavity 510. The spring 53 is located between the limiting part 522 and the locking block 52.

[0034] The connecting platform 2 includes a connecting hook 21 and a wire feeding frame 22. The connecting hook 21 is located on the top of the wire feeding frame 22 and is hinged to the lifting end 11. A self-locking winding reel 23 is rotatably connected between the wire feeding frames 22. A partition plate 231 is provided in the middle of the self-locking winding reel 23 to divide the winding reel 23 into two independent wire reels. One wire reel is used to install the first wire rope 3, and the other wire reel is used to install the second wire rope 31.

[0035] The cable-laying frame 22 is fixedly connected to a front connecting post 24 and a rear connecting post 25 at both ends. The outer peripheral wall of the front connecting post 24 is rotatably connected to a first rotating ring 241 and a second rotating ring 242. The outer peripheral wall of the rear connecting post 25 is rotatably connected to a third rotating ring 243 and a fourth rotating ring 244. The first rotating ring 241 is fixedly connected to one end of the first lifting rope 401, the second rotating ring 242 is fixedly connected to one end of the second lifting rope 402, the third rotating ring 243 is fixedly connected to one end of the third lifting rope 403, and the fourth rotating ring 244 is fixedly connected to one end of the fourth lifting rope 404.

[0036] In one embodiment, the lifting equipment prevents the aluminum alloy profile from deforming during lifting.

[0037] Specifically, after adjusting the lifting end 11 to a suitable position, connect the connecting hook 21 to the lifting end 11, place the center of the profile 6 between the support plate 41 and the pressure plate 5, and then pull the first wire rope 3 and the second wire rope 31 to fix them to both ends of the profile 6 respectively. When the wire rope reaches the suitable position, the winding reel 23 self-locks to limit the length of the wire rope. At this time, both ends of the profile 6 have been connected.

[0038] Pull the locking block 52 outward with both hands. Due to the resistance of the limiting part 522, the spring 53 is compressed and generates elastic force. The supporting parts 523 are all disengaged from the first through hole 511, the second through hole 512, the third through hole 513 and the fourth through hole 514. At this time, the pressure plate 5 is moved to the top surface of the profile 6. The pressure plate 5 moves along the first suspension rope 401, the second suspension rope 402, the third suspension rope 403 and the fourth suspension rope 404. When the pressure plate 5 reaches the top of the profile 6, the locking block 52 is released. At this time, the elastic potential energy of the spring 53 is released, and the supporting parts 523 return to the corresponding through holes. At the same time, the first suspension rope 401 in the first through hole 511, the second suspension rope 402 in the second through hole 512, the third suspension rope 403 in the third through hole 513 and the fourth suspension rope 404 in the fourth through hole 514 are resisted to fix the position of the pressure plate 5 and prevent the pressure plate 5 from shifting.

[0039] like Figure 6 As shown, the pallet 41 can also be used for small-sized profiles 6 by utilizing its own flexibility, so that the pallet 41 itself can cover the small-sized profiles 6 to adapt to the hoisting and transportation of profiles of various sizes.

[0040] In summary, this device uses a first steel wire rope 3 and a second steel wire rope 31 to fix both ends of the profile 6, and a load-bearing lifting member 4 to fix the middle position of the profile 6. When the lifting end 11 moves the profile 6, the two ends and the middle position of the profile 6 are supported by three points, making the profile 6 more stable during the transfer. By setting up a pressure plate 5, the center of the profile 6 is wrapped between the pressure plate 5 and the support plate 41 to prevent the center of the profile 6 from deforming, thus improving the hoisting efficiency. It solves the technical problem that the middle of the long lightweight aluminum alloy profile is prone to bending and deformation due to gravity and unreasonable hoisting methods during the hoisting process.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
