Description

Technical Field

[0001] This utility model relates to the field of steel beam hoisting technology, and more specifically, to a detachable lifting hook for steel beam hoisting. Background Technology

[0002] In steel structure installation, steel beam hoisting is a crucial step. Currently, based on the weight of the steel beams, sling connection methods are mainly divided into two categories: when the steel beam is heavy, lifting lugs need to be pre-welded onto the beam, and shackles pass through these lugs to connect with the slings; when the steel beam is light, hoisting holes need to be drilled at the edge of the beam, and shackles pass directly through these holes to complete the connection. However, both methods require prefabrication in the factory or on-site, making it impossible to quickly adjust the connection structure according to actual hoisting needs, thus affecting construction efficiency. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a detachable lifting hook for steel beam hoisting, which solves the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] A detachable lifting hook for steel beam hoisting includes a lifting component and a lateral fixing assembly. The lifting component includes a lifting plate and a connecting arm. The connecting arm has a first connecting hole, a second connecting hole, and a third connecting hole. The top of the lifting plate is hinged to the first connecting hole. A pressure roller is provided at the second connecting hole, and an ear buckle is provided at the third connecting hole. Reinforcing plates are symmetrically arranged on both sides of the lifting plate. Mounting portions are provided at the bottom of the lifting plate and the reinforcing plates. The lateral fixing assembly includes an outer cylinder. Telescopic pressure rods are provided in the two opening directions of the outer cylinder. The outer cylinder is fixedly mounted on the mounting portion.

[0006] In this embodiment, the connecting arm is formed by two parallel long plates, wherein the second connecting hole and the third connecting hole are located at the two ends of the side of the long plate, and the first connecting hole is located on the side of the long plate near the second connecting hole.

[0007] In this embodiment, the side of the hoisting plate is L-shaped, and its top has an inwardly inclined extension. The side of the extension has a through hole, which is hinged to the first connection hole by a bolt.

[0008] In this embodiment, the two reinforcing plates are connected to the lifting plate by short ribs.

[0009] In this embodiment, the reinforcing plate and the lifting plate have coaxial openings on their sides near the bottom, and the openings form the mounting portion for fixing the outer cylinder.

[0010] In this embodiment, square holes are provided at both ends of the outer cylinder, and an opening is provided on the outer side of the outer cylinder near both ends.

[0011] In this embodiment, the opening is connected to the top and bottom of the square hole, and the two sides of the square hole located at the square hole are arc structures.

[0012] In this embodiment, a hand-tightening nut is movably disposed in the opening.

[0013] In this embodiment, the telescopic pressure rod includes a threaded rod with a planar top and bottom. The threaded rod is movably disposed in the square hole and is threadedly connected to the hand-tightening nut. A pressure plate is provided at the end of the threaded rod.

[0014] In this embodiment, the opening is located on the outside of the reinforcing plate.

[0015] The beneficial effects of this utility model are as follows: During hoisting, the L-shaped structure of the hoisting plate hooks onto the bottom of the steel beam, and the third connecting hole of the connecting arm bears an upward pulling force, causing the pressure roller at the second connecting hole to press down on the top of the steel beam, forming an upper and lower clamping fixation; the rubber layer enhances friction and ensures connection stability. For channel steel structures, the outer cylinder of the transverse fixing component is fixed to the hoisting plate through the installation part, and the threaded rod of the telescopic pressure rod is adjusted by hand-tightening the nut so that the pressure plate abuts against the inner wall of the channel steel, achieving transverse limitation and preventing initial hoisting detachment. Compared with the prior art, it avoids the performance degradation of the heat-affected zone caused by welding the lifting lugs and the subsequent cutting process, or the damage to the flange integrity caused by drilling hoisting holes; no prefabrication is required, and the connection structure can be quickly adjusted according to hoisting requirements, improving construction efficiency; by removing the transverse fixing component, it can be adapted to I-beams, H-beams, or angle steel, expanding the application scenarios; the pressure roller and the rubber layer of the hoisting plate cooperate to clamp, combined with the transverse pressure plate limitation in the channel steel scenario, effectively preventing the risk of hoisting slippage.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] like Figures 1-5 As shown, this utility model provides a detachable lifting hook for steel beam hoisting, including a lifting component 1 and a transverse fixing component 2. The lifting component 1 includes a lifting plate 11 and a connecting arm 13. The connecting arm 13 has a first connecting hole 131, a second connecting hole 132 and a third connecting hole 133. The top of the lifting plate 11 is hinged to the first connecting hole 131. A pressure roller 15 is provided at the second connecting hole 132 and an ear buckle 14 is provided at the third connecting hole 133. Reinforcing plates 12 are symmetrically arranged on both sides of the lifting plate 11. An installation part 16 is provided at the bottom of the lifting plate 11 and the reinforcing plate 12. The transverse fixing component 2 includes an outer cylinder 21. Telescopic pressure rods 22 are provided in the two opening directions of the outer cylinder 21. The outer cylinder 21 is fixedly mounted on the installation part 16.

[0026] It should be noted that this hook is suitable for steel beams with channel steel or steel column structures. If I-beams, H-beams or angle steel are to be used, the transverse fixing component 2 of this device needs to be removed and the flanges can be clamped and fixed directly by the lifting plate 11 and the pressure roller 15.

[0027] In this embodiment, the connecting arm 13 is formed by two parallel long plates, wherein the second connecting hole 132 and the third connecting hole 133 are located at the two ends of the side of the long plate, the first connecting hole 131 is located on the side of the long plate near the second connecting hole 132, and the lifting ring is hinged to the third connecting hole 133 by bolts.

[0028] In this embodiment, the pressure roller 15 is hinged to the second connection hole 132 by bolts, and the outside of the pressure roller 15 is covered with a rubber layer.

[0029] Furthermore, the side of the lifting plate 11 is L-shaped, and its top has an inwardly inclined extension. The side of the extension has a through hole, which is bolted to the first connecting hole 131. That is, when the lifting plate 11 hooks the bottom of the steel beam, the third connecting hole 133 of the connecting arm 13 is subjected to an upward pulling force, and the pressure roller 15 presses down on the top of the steel beam to form a fixation. A rubber layer is also provided on the contact surface between the lifting plate 11 and the steel beam, which cooperates with the rubber layer of the pressure roller 15 to ensure the stability of the connection.

[0030] In this embodiment, the two reinforcing plates 12 are connected to the lifting plate 11 by short ribs.

[0031] In this embodiment, the reinforcing plate 12 and the lifting plate 11 have coaxial openings on their sides near the bottom, forming a mounting portion 16 for fixing the outer cylinder 21.

[0032] Furthermore, square holes are provided at both ends of the outer cylinder 21, and openings 211 are provided on the outer side of the outer cylinder 21 near both ends.

[0033] Furthermore, the opening 211 is connected to the top and bottom of the square hole, and the two sides of the square hole at the square hole are arc structures, and a hand-tightening nut 23 is movably installed in the opening 211.

[0034] Furthermore, the telescopic pressure rod 22 includes a threaded rod 221, the top and bottom of which are planar structures. It is movably disposed in a square hole and threadedly connected to a hand-tightening nut 23. A pressure plate 222 is provided at the end of the threaded rod 221.

[0035] That is, in the scenario of hoisting channel steel, the opening of the channel steel is facing downwards. At this time, by turning the hand-tightening nut 23, the two threaded rods 221 are moved outwards, so that the two pressure plates 222 respectively come into contact with the two sides of the inside of the channel steel. The purpose is to initially fix the hook before the hoisting equipment works, so as to avoid falling off during the initial hoisting process.

[0036] In this embodiment, the opening 211 is located on the outside of the reinforcing plate 12, which facilitates the adjustment of the hand-tightening nut 23.

[0037] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
