Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a steel coil hoisting tool that is easy to adjust. Background Technology

[0002] Steel coils are a common form of metal product, typically formed from steel through a series of complex processing techniques. They play a crucial role in the entire steel production process. In actual production, to meet the requirements of seamless transitions between different processes and to facilitate subsequent transportation and storage, these steel coils often require specialized lifting equipment for movement.

[0003] A search revealed a Chinese patent document disclosing a C-type lifting device for preventing damage from steel coils during lifting [Application No.: 201721417131.5; Publication No.: CN 207877095U]. This C-type lifting device for preventing damage from steel coils is characterized by comprising an anti-collision device and an anti-abrasion device. The anti-collision device includes a spring, a large bolt, a positioning block, and a fixing plate. The positioning block is welded to the vertical arm of the C-type lifting device, and the fixing plate, spring, and positioning block are connected by the large bolt. The anti-abrasion device includes a heat-resistant composite plate and small bolts, and the heat-resistant composite plate is connected to the fixing plate by the small bolts.

[0004] The C-type lifting tool disclosed in this patent only contacts the steel coil at a single lateral position when lifting it, resulting in single-point stress on the coil and making it prone to edge damage. Therefore, it is particularly necessary to design an easily adjustable steel coil lifting fixture to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an easily adjustable steel coil hoisting fixture.

[0006] To achieve the above objectives, the technical solution of this utility model is: an easily adjustable steel coil lifting fixture, comprising an L-shaped lifting body, a lifting lug and a counterweight fixed at one end of the lifting body, the other end of the lifting body connected to the middle of a crossbeam, a lower support arm fixed at each end of the crossbeam, and an upper support arm connected to the other end of the lifting body via an adjustable structure, wherein the length of the upper support arm is greater than the length of the lower support arm, and a rubber block is fixed at the front end of the upper support arm.

[0007] The adjustable structure includes several connecting holes on the other end of the lifting device body and a connecting block located at the rear end of the upper support boom. The connecting block can be inserted into any one of the connecting holes. The connecting block also has a threaded section with a nut threaded onto it, and the nut abuts against the other end of the lifting device body. A support platform corresponding to the position of each connecting hole is fixed on the other end of the lifting device body.

[0008] An arc-shaped reinforcement is also fixed in the middle of the crossbeam.

[0009] The other end of the lifting device also has a handle.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are: This tooling, by setting up upper and lower support booms, enables the steel coil to be supported at multiple points in the lateral direction, effectively avoiding the problem of edge damage to the steel coil caused by single-point force application in traditional C-type lifting tools.

[0012] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0013] like Figure 1-3 As shown, this easily adjustable steel coil lifting fixture includes an L-shaped lifting body 1. One end of the lifting body 1 is fixed with a lifting lug 2 and a counterweight 3, which are existing technologies. The other end of the lifting body 1 is connected to the middle of a crossbeam 7. Lower support arms 5 are fixed to both ends of the crossbeam 7. The other end of the lifting body 1 is connected to an upper support arm 10 through an adjustable structure. The length of the upper support arm 10 is greater than the length of the lower support arms 5. A rubber block 4 is also fixed to the front end of the upper support arm 10. In this embodiment, a three-point support structure is formed by using one upper support arm 10 and two lower support arms 5. This structure can more stably support the steel coil and prevent the steel coil from shaking or shifting during lifting.

[0014] The adjustable structure includes several connecting holes 1a on the other end of the lifting device body 1 and a connecting block 10a located at the rear end of the upper support boom 10. The connecting block 10a can be inserted into any of the connecting holes 1a. The connecting block 10a also has a threaded section 10b, on which a nut 11 is threaded and connected, and the nut 11 abuts against the other end of the lifting device body 1. A support platform 8 is fixed on the other end of the lifting device body 1, corresponding to the positions of the connecting holes 1a. The design of the adjustable structure allows the position of the upper support boom 10 to be flexibly adjusted according to the actual size of the steel coil. After the connecting block 10a is inserted into the connecting holes 1a at different positions, it is firmly fixed by the cooperation of the nut 11 and the support platform 8, which greatly improves the versatility of the tooling. In this embodiment, the upper support boom 10, the connecting block 10a and the threaded section 10b are made of the same steel.

[0015] An arc-shaped reinforcement 6 is also fixed in the middle of the crossbeam 7. The arc-shaped reinforcement 6 enhances the structural strength of the crossbeam 7 and ensures stability during hoisting.

[0016] The other end of the main body 1 of the lifting device also has a handle 9, which makes it easier for the operator to grip and operate the device when adjusting and using it.

[0017] This tooling, by setting up an upper support boom 10 and a lower support boom 5, enables the steel coil to be supported at multiple positions in the lateral direction, effectively avoiding the problem of steel coil edge damage caused by single-point force application in traditional C-type lifting tools.

[0018] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0019] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
