Problems solved by technology
[0003] Aiming at the problem of setting hoisting points for extra-high and extra-large steel structure towers in petrochemical installations, such as flare towers, exhaust gas emission towers, etc., the conventional method is to weld lifting lugs on the top of the tower or use a bundled form for tower hoisting construction , when hoisting, according to the tower structure and material characteristics, such as thin walls, small column specifications and other factors, the strength cannot be guaranteed, and it is easy to cause damage to the tower body and seriously damage the hoisting ropes, which poses safety risks and is time-consuming and laborious. Is the tower hoisting a technical problem of construction

Embodiment Construction
[0018] Attached below Figure 1 to Figure 6 The present invention is further described.
[0019] A reusable porous suspension cover for hoisting a steel structure tower, including a crane 5, a steel wire rope, a shackle and a tower column 6 to be hoisted, the hoisting end of the crane 5 is connected to the shackle through a wire rope, and the suspension cover is composed of a lifting lug plate 2. Bottom plate 1 and diagonal tie bars 3 are composed. Hanging lug plate 2 is welded to the middle of bottom plate 1. Diagonal tie bars 3 are welded between hanging lug plate 2 and bottom plate 1 to play a role of reinforcement and stability. Lifting lug plate 2 and Shackle connection, lug plate 2, shackle and wire rope together form the main hoisting system, and then connect with the hook, 1 There are multiple concentric circles on the bottom plate, and connecting holes 4 are uniformly arranged on each concentric circle, Bottom plate 1 The connecting hole 4 and the stud bolts are conn...

The invention discloses a reusable multi-hole-stage hoisting cover used for hoisting a steel-structure tower. The reusable multi-hole-stage hoisting cover comprises a crane, a steel wire rope, a shackle and a to-be-hoisted tower vertical post; the hoisting end of the crane is connected with the shackle through the steel wire rope; the hoisting cover consists of a hoisting lug plate, a bottom plateand diagonal draw steel bars; the hoisting lug plate is connected with the shackle; the hoisting lug plate, the shackle and the steel wire rope jointly form a main hoisting system; multiple concentric circles are marked on the bottom plate; each concentric circle is uniformly provide with connection holes; and the bottom plate is connected with a top plate of the to-be-hoisted tower vertical postthrough the connection holes and studs. By adopting the hoisting cover, damage-free hoisting of the steel-structure tower can be realized; and the hoisting cover is safe and convenient.
Description
technical field [0001] The invention relates to the technical field of hoisting, in particular to a reusable porous-level hanging cover used for hoisting a steel structure tower. Background technique [0002] In the prior art, the tower frame refers to a towering steel structure, an unshaped product, and the tower frame structure is designed according to the requirements according to different engineering conditions; the hanging cover refers to the lifting point structure connected with the workpiece by bolts for lifting or pulling equipment; hoisting is It refers to the work in which the workpiece is lifted and installed to the specified position under the action of the hoisting machinery. [0003] For the setting of hoisting points for extra-high and extra-large steel structure towers in petrochemical plants, such as flare towers, exhaust gas emission towers, etc., the conventional method is to weld lifting lugs above the tower or use a bundled form for tower hoisting cons...
