Description

Technical Field

[0001] The utility model relates to the technical field of steel structure hoisting, and more specifically, to a steel structure hoisting device. Background Art

[0002] Steel beams, also known as I-beams, are long strips of steel with an I-shaped cross section. I-beams are widely used in buildings or other metal structures. When I-beams are used in buildings, other structures are often hoisted on the steel beams to hoist steel parts and increase the convenience of workers in construction. For example, a steel structure hoisting device disclosed in the prior art announcement number (CN213738159U) has two hoisting arms installed in the same way when assembling the hoisting arms. First, the extension rod is embedded in the installation slot, and the clamping plate is clamped into the slot. The extension rod is slid to adjust the length of the hoisting arm, and then the limit bolt is tightened. The extension rod is fixed to the wall, and then the connecting ear is installed with the bracket, and the first hinge bolt is inserted to form a hinge connection between the connecting ear and the bracket, and then the second hinge bolt is inserted at the other end of the connecting ear to hinge the connecting ear with the connecting plate. Through the two hinges, the angle of the hoisting arm during installation can be adjusted, which improves the adaptability of the steel beam when connected with other devices.

[0003] When the above device is in use, two lifting arms are arranged on the steel beam lifting connection structure, so that the lifting of the steel beam lifting connection structure is more stable, and the angle between the lifting arm and the steel beam lifting connection structure is adjustable by rotating the lifting arm and the steel beam lifting connection structure. However, when lifting heavier objects, the large weight can easily cause the connection between the hinge plate and the clamping plate to loosen, thereby failing to maintain its own angle, affecting the stability of the lifting.
