Description

Technical Field

[0001] This application relates to the field of steel structure hoisting technology, and in particular to a device for hoisting steel structures. Background Technology

[0002] The safety and efficiency of steel column hoisting operations directly affect the progress and quality of the entire steel structure construction. Existing equipment uses clamps to grab steel columns, but during the hoisting process, there is a problem of not having fixed balance points, and there is also the risk that the steel column may fall off, threatening the safety of construction personnel.

[0003] Currently, through market research on several U-shaped lifting rings, it has been found that the U-shaped lifting rings on the market do not have the practical application capability when lifting steel columns, nor do they meet the requirements of central force bearing. This leads to the phenomenon that the lifting ring is not bearing force at the center point during the lifting process, which is judged as a violation. This undoubtedly has a significant impact on the lifting schedule and the safety risks during the lifting process.

[0004] Therefore, this application provides a device for hoisting steel structures. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a steel structure hoisting device that overcomes these deficiencies. It aims to solve the problem that, based on market research of several U-shaped lifting rings, it was found that none of the commercially available U-shaped lifting rings possess the practical application capability for hoisting steel columns, nor do they meet the requirements for central force bearing. This leads to situations where the lifting ring is not bearing force at the center point during hoisting, resulting in violations. This undoubtedly has a significant impact on the hoisting schedule and safety risks during the hoisting process.

[0006] To achieve the above objectives, this application provides the following technical solution: a steel structure hoisting device, comprising a wing plate, wherein a plurality of transverse bolt holes are provided inside the wing plate, and a hoisting mechanism is connected to the transverse bolt holes; a U-shaped lifting ring one and a U-shaped lifting ring two are respectively provided on both sides of a connecting plate; a connecting hole is provided at both ends of the connecting plate; a fixing device is provided at the open end of the U-shaped lifting ring one and the U-shaped lifting ring two; the end of the U-shaped lifting ring one away from the fixing device is sleeved with the connecting plate; the U-shaped lifting ring two is hinged to the connecting plate through the fixing device; and the U-shaped lifting ring one is connected to the transverse bolt holes through the fixing device.

[0007] By adopting the above technical solution, and by setting up a connecting plate, U-shaped lifting ring one, U-shaped lifting ring two, and two sets of fixing devices, one end of U-shaped lifting ring one passes through a set of connecting holes in the connecting plate and connects to the connecting plate. U-shaped lifting ring two is connected to the connecting plate through the fixing devices connected to it. Then, U-shaped lifting ring one is connected to the transverse bolt hole through the fixing devices connected to it, so that U-shaped lifting ring one is fixed to the wing plate. At this time, U-shaped lifting ring two, with the fixing device as the axis, can rotate 90° to keep the U-shaped arc top of U-shaped lifting ring two facing upward and fixed to the wire rope for force, which can realize the center force during hoisting, avoid the off-center load, meet the needs of rapid connection, and improve the safety and stability of hoisting.

[0008] As a preferred technical solution of this application, the fixing device includes two sets of connecting handles, which are fixedly installed at both ends of one side of the U-shaped lifting ring. A safety pin is inserted between the two sets of connecting handles, and a limit mechanism is provided at one end of the safety pin.

[0009] By adopting the above technical solution, the opening between the two sets of connecting handles is sealed by a safety pin, and the safety pin is limited by a limiting mechanism, which effectively prevents the U-shaped lifting ring one and U-shaped lifting ring two from loosening or falling off during the lifting process, and further improves the safety of the lifting.

[0010] As a preferred technical solution of this application, the outer surfaces of both the first U-shaped lifting ring and the second U-shaped lifting ring are set as smooth surfaces.

[0011] By adopting the above technical solution, the outer surfaces of both U-shaped lifting ring one and U-shaped lifting ring two are made into smooth surfaces, which reduces the friction between the connected parts, avoids damage to the sling, and improves the safety during use.

[0012] As a preferred technical solution of this application, the limiting mechanism includes a storage groove, which is opened on one side of the safety pin. A screw is threadedly connected to the inside of the safety pin at the storage groove. A limiting block is fixedly installed at one end of the screw, and the maximum diameter of the limiting block is larger than the diameter of the connecting hole.

[0013] By adopting the above technical solution, the limiting block is fixed to one side of the connecting handle by connecting the screw to the receiving groove. Since the maximum diameter of the limiting block is greater than the diameter of the connecting hole, the connecting handle is effectively limited, preventing it from falling off accidentally, and further improving the reliability of the hoisting device.

[0014] As a preferred technical solution of this application, the connecting plate is internally fixedly equipped with several sets of reinforcing ribs, and the several sets of reinforcing ribs are evenly distributed at both ends of the connecting plate.

[0015] By adopting the above technical solution, the strength and rigidity of both ends of the connecting plate are improved by using several sets of reinforcing ribs, thereby improving the load-bearing capacity of the connecting plate during hoisting.

[0016] As a preferred technical solution of this application, an identification layer is fixedly connected to the outer wall of the connecting plate, and the outer surface of the identification layer is engraved with a rated weight mark.

[0017] By adopting the above technical solution, the rated weight marking is engraved on the outer surface of the marking layer, which makes it convenient for construction personnel to select the appropriate connection plate for use, and facilitates use and management.

[0018] As a preferred technical solution of this application, the outer walls of the U-shaped lifting ring one, the U-shaped lifting ring two, and the connecting plate are all coated with an anti-rust coating.

[0019] By adopting the above technical solution, the corrosion resistance of U-shaped lifting ring 1, U-shaped lifting ring 2, and connecting plate is improved through the anti-rust coating, which helps to extend their service life.

[0020] The beneficial effects of this application are:

[0021] 1. By setting up a connecting plate, U-shaped lifting ring one, U-shaped lifting ring two, and two sets of fixing devices, one end of U-shaped lifting ring one passes through a set of connecting holes in the connecting plate and connects to the connecting plate. U-shaped lifting ring two is connected to the connecting plate through the fixing devices connected to it. Then, U-shaped lifting ring one is connected to the horizontal bolt holes through the fixing devices connected to it, so that U-shaped lifting ring one is fixed to the wing plate. At this time, U-shaped lifting ring two, with the fixing device as the axis, can rotate 90° to keep the U-shaped arc top of U-shaped lifting ring two facing upward and fixed to the wire rope for force, which can realize the center force during hoisting, avoid the off-center load, meet the needs of rapid connection, and improve the safety and stability of hoisting.

[0022] 2. By using a safety pin to lock the opening between two sets of connecting handles, and by using a limiting mechanism to limit the safety pin, the loosening or falling off of U-shaped lifting ring one and U-shaped lifting ring two during the lifting process is effectively prevented, further improving the safety of the lifting.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4 A steel structure hoisting device includes a wing plate 1, with several sets of transverse bolt holes 101 inside the wing plate 1. A hoisting mechanism is connected to the transverse bolt holes 101. U-shaped lifting rings 3 and 4 are respectively provided on both sides of a connecting plate 2. Connecting holes are provided at both ends of the connecting plate 2. Fixing devices 5 are provided at the open ends of both U-shaped lifting rings 3 and 4. The end of U-shaped lifting ring 3 away from the fixing device 5 is sleeved with the connecting plate 2. U-shaped lifting ring 4 is hinged to the connecting plate 2 through the fixing device 5. U-shaped lifting ring 3 is connected to the transverse bolt holes 101 through the fixing device 5. The outer surfaces of both U-shaped lifting rings 3 and 4 are rounded.

[0030] By setting up a connecting plate 2, U-shaped lifting ring 3, U-shaped lifting ring 4, and two sets of fixing devices 5, one end of U-shaped lifting ring 3 passes through a set of connecting holes in the connecting plate 2 and connects to the connecting plate 2. U-shaped lifting ring 4 is connected to the connecting plate 2 through the fixing devices 5. Then, U-shaped lifting ring 3 is connected to the transverse bolt hole 101 through the fixing devices 5, so that U-shaped lifting ring 3 is fixed to the wing plate 1. At this time, U-shaped lifting ring 4 can rotate 90° around the fixing device 5 to keep the U-shaped arc top of U-shaped lifting ring 4 facing upward and fixed to the wire rope for force, so as to achieve the center force during hoisting and avoid the off-center load. This not only meets the needs of quick connection, but also improves the safety and stability of hoisting. By setting the outer surfaces of U-shaped lifting ring 3 and U-shaped lifting ring 4 to be smooth, the friction between the connected parts is reduced, avoiding damage to the sling and improving the safety during use.

[0031] Reference Figure 1-3The fixing device 5 includes two sets of connecting handles 501, which are fixedly installed at both ends of the same side of the U-shaped lifting ring 3. A safety pin 502 is inserted between the two sets of connecting handles 501. A limit mechanism 6 is provided at one end of the safety pin 502. The limit mechanism 6 includes a storage groove 601, which is opened on one side of the safety pin 502. A screw 602 is threadedly connected to the inside of the safety pin 502 at the storage groove 601. A limit block 603 is fixedly installed at one end of the screw 602. The maximum diameter of the limit block 603 is larger than the diameter of the connecting hole.

[0032] The safety pin 502 passes through two sets of connecting handles 501 to seal the opening between them. The safety pin 502 is then limited by the limiting mechanism 6, which effectively prevents the U-shaped lifting ring 3 and U-shaped lifting ring 4 from loosening or falling off during the lifting process, thus further improving the safety of the lifting. The limiting block 603 is fixed to one side of the connecting handle 501 by connecting the screw 602 to the receiving groove 601. Since the maximum diameter of the limiting block 603 is larger than the diameter of the connecting hole, the connecting handle 501 is effectively limited, preventing it from falling off accidentally, thus further improving the reliability of the lifting device.

[0033] Reference Figure 1 , Figure 4 The connecting plate 2 has several sets of reinforcing ribs 8 fixedly installed inside, and the sets of reinforcing ribs 8 are evenly distributed at both ends of the connecting plate 2; the outer walls of the U-shaped lifting ring 3, the U-shaped lifting ring 4, and the connecting plate 2 are all coated with an anti-rust coating; the sets of reinforcing ribs 8 improve the strength and rigidity of both ends of the connecting plate 2, and improve the load bearing capacity of the connecting plate 2 during the hoisting process; the anti-rust coating improves the corrosion resistance of the U-shaped lifting ring 3, the U-shaped lifting ring 4, and the connecting plate 2, which helps to extend their service life.

[0034] Reference Figure 1-3 The outer wall of the connecting plate 2 is fixedly connected to the marking layer 9, and the outer surface of the marking layer 9 is engraved with the rated weight marking. The rated weight marking on the outer surface of the marking layer 9 makes it convenient for construction personnel to select the appropriate connecting plate 2 for use, and facilitates use and management.

[0035] Working principle: By setting up a connecting plate 2, U-shaped lifting ring 3, U-shaped lifting ring 4, and two sets of fixing devices 5, one end of U-shaped lifting ring 3 passes through a set of connecting holes of the connecting plate 2 and connects to the connecting plate 2. U-shaped lifting ring 4 is connected to the connecting plate 2 through the fixing device 5. Then, U-shaped lifting ring 3 is connected to the transverse bolt hole 101 through the fixing device 5, so that U-shaped lifting ring 3 is fixed to the wing plate 1. At this time, U-shaped lifting ring 4 can rotate 90° around the fixing device 5 as the axis point, keeping the U-shaped arc top of U-shaped lifting ring 4 facing upward and fixed to the wire rope for force, so as to realize the center force during hoisting. The opening between the two sets of connecting handles 501 is sealed by the safety pin 502 passing through the two sets of connecting handles 501, and the safety pin 502 is limited by the limiting mechanism 6.
