Description

Technical Field

[0001] The utility model relates to the technical field of steel bar installation, in particular to a modular hoisting device suitable for vertical main bars of high piers. Background Art

[0002] With the continuous development of national infrastructure, the number of super-high and super-large piers has increased. Since the size of steel bars is usually large under such conditions, steel bar installation has become a major difficulty in construction. The traditional steel bar installation solution is to bundle the semi-finished steel bars and then hoist them to the aerial work platform with a crane, and then install and position them one by one by manually cooperating with the crane. This method has the disadvantages of low steel bar installation efficiency, many aerial operations, high safety risks, and difficulty in ensuring installation accuracy.

[0003] The utility model patent with publication number CN218538934U discloses a combined lifting device for integral lifting of steel bars of super-high thin-walled piers, comprising an upper crossbeam and a lower crossbeam, the upper crossbeam comprising two upper clamping plates arranged side by side, a first limiting hole with uniform intervals is provided at the connection of the two upper clamping plates, lifting rings are symmetrically provided at both ends of the upper side of the upper clamping plates, the lower crossbeam comprises two lower clamping plates arranged side by side, a through hole corresponding to the first limiting hole is provided at the connection of the two lower clamping plates, second limiting holes with uniform intervals are also provided at the connection of the lower clamping plates, steel plates fixedly connected to the corresponding two ends of the upper clamping plates are provided at both ends of the lower clamping plates, and matching transverse sleeves are provided on both the upper clamping plates and the lower clamping plates. In the disclosed technology, a pin is passed through a transverse sleeve to combine the two halves of the hoist into a complete hoist to clamp the steel bars and hoist them to the required position of the project. During use, the pin needs to be frequently installed and removed to complete the placement of the steel bars. The hoist is made of I-beams, and frequent installation and removal of the pin is very inconvenient. In addition, when the pin is removed, the clamp loses external force, resulting in all the steel bars on the clamp being in an unrestrained state, which will bring safety hazards during construction.
