Description

Technical Field

[0001] The utility model relates to the technical field of steel structure component processing, in particular to a portable corbel lifting device. Background Art

[0002] In the field of prefabricated steel structures, in order to ensure the connection accuracy between steel columns and steel beams, H-steel corbels are generally set on the side of the steel columns and connected to the corresponding steel beams with high-strength bolts. This type of H-steel corbel is widely used. During the production process, due to the high requirements for docking accuracy with steel beams and strict requirements for the rigidity of the parent material, the H-steel corbels were previously lifted by ordinary hooks to the position of the parent material, which often resulted in damage to the parent material and unstable lifting, affecting the dimensional accuracy and rigidity of the H-steel corbels.

[0003] To improve the convenience, safety, and minimal damage to the base material of H-steel brackets with high-strength bolt holes, a lifting tool specifically designed for H-steel brackets with high-strength bolt holes has been designed. Due to its specificity, this tool is easy to operate, efficient, safe, and stable. Utility Model Content

[0004] The utility model designs a portable corbel lifting device for an H-steel corbel with bolt holes, which can realize the rapid lifting of the H-steel corbel component with bolt holes.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A portable corbel hoist includes a lifting ring and a threaded sleeve. One end of the lifting ring is used to mount a hook, while the other end has a notch in the middle for attaching or removing the hook. Both ends of the notch are threaded sections for installing the threaded sleeve. The notched end is used for mounting a conventional hook, while the unnotched end is used to install the lifting ring. The threaded notch in the lifting ring facilitates quick replacement of subsequent lifting rings, and the addition of a threaded sleeve reinforces the strength of the notch in the lifting ring, improving lifting safety.

[0007] Furthermore, a certain number of hanging rings are put inside the hanging ring, and the hanging rings rotate and move inside the hanging rings to meet the relaxation of different angles. Sufficient gaps are maintained between the hanging rings, and adjusting the position and direction of the hanging rings is more convenient and practical.

[0008] Furthermore, one end of the hanging ring is hung on the end without a notch of the hanging ring, and the other end is fixed to the main rod of the hook. The hanging ring is used to rotate and move in the hanging ring to adjust the spatial position of the main rod of the hook.

[0009] Furthermore, one end of the hook main rod is fixed to the hanging ring, and its spatial position is adjusted by rotating and moving the hanging ring. A secondary hook rod is fixed to the other end, forming an L-shaped rod with an 80° angle between them. The hook main rod serves as a rigid component for the subsequent mounting of the tension member of the H-steel bracket.

[0010] Furthermore, one end of the secondary hook rod is fixed to the main hook rod, forming an 80° angle between them. The other end of the secondary hook rod passes through a bolt hole in the web of the H-steel corbel, serving as a carrier for mounting the H-steel corbel. The main hook rod and the secondary hook rod form an L-shaped tension member of the H-steel corbel.

[0011] Furthermore, the hanging ring, the hook main rod and the hook secondary rod are combined into a body, wherein in the two combined bodies, the hook secondary rod is used to pass through the bolt holes on the H-steel corbel web in opposite directions, that is, inserted into the bolt holes of the H-steel corbel web from both sides of the H-steel corbel web.

[0012] Threaded sections are provided on both sides of the notch, and the threaded sleeves are threadedly connected to the two sides of the notch.

[0013] The utility model is a special lifting device designed for H-steel corbels with holes. It has a simple structure and is light in weight. Its components are only a lifting ring, a threaded sleeve, a hanging ring, a main hook rod and a secondary hook rod. The operation is easy to understand. During use, the position of the main hook rod is adjusted and the secondary hook rod is passed through the bolt holes on the H-steel corbel to complete the lifting work. The portable corbel lifting device has high safety. The use of fixed position holes on the H-steel makes the lifting more stable, does not shake during lifting, and is more convenient for loading and unloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] This embodiment discloses a portable bracket hoist, combined with Figures 1 to 3 As shown, the lifting tool mainly includes a lifting ring 1 connected to a common lifting hook (not shown in the figure), a threaded sleeve 2 at the notch 11, a hanging ring 3 mounted on the lifting ring 1, a hook main rod 4 connected to the hanging ring 3, and a hook secondary rod 5.

[0021] Among them, the main function of the lifting ring 1 is to accommodate the hanging ring 3 and connect the remaining lifting hooks. By adding multiple hanging rings 3, the lifting requirements of H-steel brackets of different specifications can be met.

[0022] Part of the notch 11 of the lifting ring 1 is a threaded segment 12 for subsequent installation of the threaded sleeve 2 to prevent other components from falling off the lifting ring 1 and to reinforce the strength of the lifting ring 1 at the notch 11 .

[0023] The hanging ring 3 added to the lifting ring 1 is welded and fixed to the hook. The diameter of the elliptical hanging ring 3 is set to 3 times the diameter of the round rod of the lifting ring 1, so that the hanging ring 3 can rotate at a large angle in the lifting ring 1 during use, thereby expanding the angle between two or more hooks to meet the lifting needs of H-steel brackets of different sizes.

[0024] The hook is divided into a main hook rod 4 and a secondary hook rod 5. The secondary hook rod 5 forms an angle of 80° with the main hook rod 4, and the two are in opposite directions, so as to smoothly pass through the bolt holes on the web 6 of the H-steel corbel from both sides, and also avoid unhooking caused by the shaking of the H-steel corbel during lifting. When the secondary hook rod 5 passes through the bolt hole position of the web 6 of the H-steel corbel, a certain angle can prevent the H-steel corbel from falling off.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
