Clamping and hoisting device

Abstract

The invention discloses a clamping and hoisting device. The clamping and hoisting device comprises an upper clamping plate, a lower clamping plate, two vertical clamping plates and a hoisting plate; the upper clamping plate and the lower clamping plate are the same in structure, and each of the upper clamping plate and the lower clamping plate comprise two oppositely-arranged horizontal plates; the upper ends of the vertical clamping plates are connected with one end of the upper clamping plate, and the lower ends of the vertical clamping plates are connected with one end of the lower clampingplate; and first connecting holes are formed in the middles of the upper clamping plate, the lower clamping plate and the two vertical clamping plates, and the hoisting plate is connected with the first connecting holes. The clamping and hoisting device has the advantages that processing manufacturing is simple, construction operation is convenient and quick, safety and stability are achieved, repeated disassembly and assembly for use is achieved, initial damage of rework treatment to the components is avoided, cost is low, construction cost is reduced, and construction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of construction equipment, and in particular relates to a clamping and hanging device. Background technique [0002] Due to its mechanical characteristics (high rigidity) and process equipment layout requirements, box-shaped members are often used in frame structures; box-shaped members are formed by welding two webs and two flanges. [0003] In the prior art, box-shaped components are manufactured by combining electroslag welding and submerged arc welding to weld the web and flange plates. During the welding construction, welding deformation will occur due to the distribution of welding stress. The torsional buckling is easy to occur during welding construction; the torsional buckling deformation of box-shaped members is difficult to control. At present, there is no special correction equipment for the deformation of box-shaped members, resulting in the horizontality and verticality of box-shaped members. requiremen...
