Description

Technical Field

[0001] This utility model relates to the field of hoisting technology for large metal components, and in particular to a deformation-resistant support device for hoisting large metal components. Background Technology

[0002] Large castings refer to large metal components formed through casting processes. The core issue lies in addressing shrinkage defects, which requires achieving a balanced solidification process through thermal equilibrium control. Key methods include using chills to accelerate solidification in thick sections, employing high-heat-storage materials such as chromite sand, using multiple ingates to disperse heat, optimizing the feeding effect by tilting the mold, and reinforcing large metal components with anti-deformation support devices during hoisting.

[0003] As shown in the reference case "Lifting Device and Crane" announcement number "CN221587808U", by using a support member to support the building component, and the size of the support member is greater than or equal to the size of the building component, the mutual compression between the first connector and the building component is transformed into compression between the first connector and the support member. This makes it impossible for the first connector and the building component to come into contact during the lifting process, which can prevent the edge of the building component from being damaged or deformed by the first connector during the lifting process, thereby affecting the use of the building component.

[0004] According to the aforementioned reference materials, the device is suspended from the hook of the crane by a fixing member. The opening of the support member is placed facing the ground, and the building component is placed above the support member. The hook at one end of the first connector is removed from the first lifting member, passed through the opening of the support member, and then fixed back to the first lifting member. The position of the first lifting member relative to the building component is adjusted by moving the first lifting member. However, when lifting large metal components, the large metal components are prone to bending or local dents due to their own weight, lifting force, and inertia. This makes it inconvenient to reinforce and support the large metal components, thus reducing the lifting effect of the large metal components. Utility Model Content

[0005] Therefore, it is necessary to provide anti-deformation support devices for the hoisting of large metal components to address the problem of inconvenience in reinforcing and supporting large metal components.

[0006] The device includes two lifting devices, each with a lifting strap attached to both sides of its bottom end; a support mechanism, which provides anti-deformation support for large metal components, is located on the inner wall of the lifting straps; wherein the support mechanism includes a set of two support plates evenly arranged between the inner walls of the two lifting straps, with a fixing block fixedly connected to one end of each support plate, the fixing block engaging with one end of the support plate and engaging with the outer wall of the lifting straps; rubber pads are fixedly connected to the inner wall of each support plate; and a lifting assembly is located at the bottom end of the lifting device.

[0007] In one embodiment, the support mechanism further includes a groove formed in the inner wall of the rubber pad, and an extension rod is slidably connected between the two support plates.

[0008] In one embodiment, a fixing bolt is threaded onto one side of the support plate, one end of the fixing bolt passes through the support plate and is fixedly connected to a support block, and the other end of the support block is in contact with the extension rod.

[0009] In one embodiment, a rubber block is fixedly connected to the inner wall of the fixing block, and the other end of the rubber block is in contact with the outer wall of the lifting sling.

[0010] In one embodiment, a connecting plate is snapped onto one end of the outer wall of several of the support plates, and one end of the connecting plate extends sequentially through the inner wall of several of the support plates.

[0011] In one embodiment, both ends of the connecting plate are rotatably connected to threaded rods, one end of which passes through the connecting plate and is threadedly connected to a nut.

[0012] In one embodiment, the lifting assembly includes two traction ropes snapped onto one end of the inner wall of the lifting device, and two lifting lugs are provided below the lifting device. The lifting lugs are fixedly connected to the outer wall of the steel section, and one end of each of the two traction ropes extends through the outer surface of the two lifting lugs.

[0013] In one embodiment, a first rubber ring is fixedly connected to the inner wall of the lifting sling, and a second rubber ring is fixedly connected to the outer wall of the lifting sling.

[0014] Beneficial effects 1. The aforementioned anti-deformation support device for hoisting large metal components, when two hoisting slings work together to hoist both ends of the component, has multiple sets of support plates installed on the inner wall of the hoisting slings and in contact with the component. Two support plates are connected together by extension rods, which can support the component, provide additional support points and rigidity, and the length of the two support plates can be adjusted by the extension rods. The L-shaped fixing block cooperates with the support plate to clamp and fix the support plate. The rubber pad at the top of the support plate cooperates with the groove to increase the friction between the support plate and the component. The support block is clamped by the fixing bolts. The connecting plate can be connected with multiple support plates. The position of the connecting plate is fixed by the threaded rod and nut. This device can provide stable support for large metal components and prevent deformation of the large metal components. 2. The two traction ropes at the bottom of the lifting device are respectively connected to the two lifting lugs on the large metal component to lift the large metal component. The two traction ropes and the two lifting lugs can increase the support force of the lifting device. In addition, the lifting sling can be used to improve the stability of the lifting of the large metal component. The first rubber ring on the inner wall of the lifting sling contacts the outer wall of the mounting plate, and the second rubber ring on the outer wall of the lifting sling contacts the rubber block in the fixing block. The mounting plate can be installed and the large metal component can be supported against deformation. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 6 This invention describes a large metal component hoisting anti-deformation support device.

[0020] In one embodiment, a large metal component hoisting anti-deformation support device includes two lifting devices 100, with lifting straps 200 fastened to both sides of the bottom end of each lifting device 100; a support mechanism 300, which can provide anti-deformation support for the large metal component, is disposed on the inner wall of the lifting straps 200; wherein, the support mechanism 300 includes an array of support plates 310 evenly arranged and disposed between the inner walls of the two lifting straps 200, with two support plates 310 in one set, and a fixing block 320 fixedly connected to one end of each support plate 310, the fixing block 320 engaging with one end of the support plate 310 and fastening to the outer wall of the lifting straps 200, a rubber pad 330 fixedly connected to the inner wall of the support plate 310, and a hoisting assembly 380 disposed at the bottom end of the lifting device 100.

[0021] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the support mechanism 300 also includes a groove 340 formed in the inner wall of the rubber pad 330. An extension rod 350 is slidably connected between two support plates 310. A fixing bolt 351 is threadedly connected to one side of the support plate 310. One end of the fixing bolt 351 passes through the support plate 310 and is fixedly connected to a support block 352. The other end of the support block 352 is in contact with the extension rod 350. A rubber block 360 is fixedly connected to the inner wall of the fixing block 320. The other end of the rubber block 360 is in contact with the outer wall of the lifting belt 200. A connecting plate 370 is snapped onto one end of the outer wall of several support plates 310. One end of the connecting plate 370 passes through the inner wall of several support plates 310 in sequence. Threaded rods 371 are rotatably connected to both ends of the connecting plate 370. One end of the threaded rod 371 passes through the connecting plate 370 and is threadedly connected to a nut 372.

[0022] In this embodiment, the array support plate 310 can be snapped onto two lifting belts 200 by fixing blocks 320 at both ends. The rubber block 360 inside the fixing block 320 contacts the outer wall of the lifting belt 200. The two support plates 310 can also slide to both ends by extension rods 350 respectively to adjust the length of the support plates 310, thereby improving the support effect of the support plates 310 on large metal components. The fixing bolts 351 are threadedly connected to the support plates 310, which can drive the support blocks 352 to contact the extension rods 350 and fix the support plates 310. The connecting plate 370 can pass through multiple support plates 310, and the connecting plate 370 is fixed to multiple support plates 310 by the cooperation of the threaded rod 371 and the nut 372. This can effectively support large metal components and prevent deformation of large metal components during hoisting.

[0023] like Figure 6 As shown, the lifting assembly 380 includes two traction ropes 381 that are snapped onto one end of the inner wall of the lifting device 100. Two lifting lugs 382 are provided at the bottom of the lifting device 100. The lifting lugs 382 are fixedly connected to the outer wall of the steel section. One end of the two traction ropes 381 passes through the outer surface of the two lifting lugs 382. A first rubber ring 383 is fixedly connected to the inner wall of the lifting belt 200, and a second rubber ring 384 is fixedly connected to the outer wall of the lifting belt 200.

[0024] In this embodiment, two traction ropes 381 on one side of the bottom of the lifting device 100 pass through the inner walls of two lifting lugs 382 respectively, and then the two ends of the two traction ropes 381 are clamped on the lifting device 100, which can lift large metal components. The first rubber ring 383 on the inner wall of the lifting belt 200 contacts the outer wall of the support plate 310, and the second rubber ring 384 contacts the rubber block 360 in the fixing block 320, which can limit the installation of the support plate 310, effectively support the large metal components, and improve the lifting stability of the large metal components.

[0025] Working principle: When two lifting slings 200 are attached to both ends of the component, multiple sets of support plates 310 can be clamped onto the lifting slings 200 through the fixing blocks 320 at one end. The two support plates 310 slide to both sides through the extension rods 350 respectively. The position of the support plates 310 is adjusted according to the position of the lifting slings 200. The fixing bolts 351 are manually rotated and threaded to the support plates 310, causing the support blocks 352 to contact the extension rods 350, thus fixing the position of the support plates 310. One end of the two connecting plates 370 passes through both ends of the multiple sets of support plates 310 respectively. The two threaded rods 371 pass through both ends of the connecting plates 370 and are threaded with nuts 372, which can connect and fix the multiple support plates 310. One end of the two traction ropes 381 passes through the two lifting lugs 382 respectively and is clamped onto the lifting device 100. In conjunction with the lifting slings 200, large metal components can be lifted.
