Description

Technical Field

[0001] The utility model relates to the field of hoisting of steel structure bridges, and more specifically, to a simple hoisting device for installing steel structure bridges. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structures are prone to rust, and general steel structures need to be derusted, galvanized or painted, and need to be maintained regularly.

[0003] The Chinese patent authorization announcement number: CN216471750U provides a simple hoisting device for installing steel structure bridges. This patent can hang the components of the steel structure bridge through multiple points by setting four hooks, and is pulled upward by two pull ropes. Under the action of gravity, the pull ropes can be prevented from rotating and knotting, and the stability during the hoisting of components is better, and the safety of hoisting is higher.

[0004] Four traction ropes and hooks are arranged at the bottom of the above-mentioned simple hoisting device for hanging steel structure components. Since the traction ropes and hooks can only move up and down, and the lengths of different steel structures are different, the hanging of the hooks on steel structures of different lengths is unstable. Content of the Utility Model

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a simple hoisting device for installing steel structure bridges, which can realize that four limiting frames are fixedly installed at the lower end of the cross plate, and movable rings that can move left and right are installed inside the limiting frames. Multiple traction ropes are inserted into the lower ends of the movable rings. After the hooks at the bottom of the traction ropes hang the steel structure, the position of the movable rings can be adjusted according to the length of the steel structure, so that the distance between the horizontal traction ropes is adapted to the length of the steel structure, thereby improving the hanging stability of the steel structure and the safety of the hoisting device.
