Description

Technical Field

[0001] The utility model relates to the field of prefabricated box beam hoisting, in particular to prefabricated box beam hoisting equipment. Background Art

[0002] With the continuous development of bridge construction technology, the hoisting of prefabricated box girders, as key components in bridge construction, is particularly important.

[0003] At present, the prefabricated box girder lifting equipment on the market generally lacks the rotation function of the lifting tool. This means that during the lifting process, once the prefabricated box girder needs to adjust the direction or angle, the construction personnel often need to move the entire lifting equipment through complex operations, which is not only inefficient, but also greatly increases the difficulty of operation and safety risks. At the same time, this limitation also makes the lifting equipment seem powerless when dealing with complex construction environments, especially in situations where space is limited or the position of the box girder needs to be precisely adjusted. In addition, the lifting equipment in the existing technical solutions often lacks flexible control over the lifting and lowering of the lifting tools. This results in the inability of construction personnel to adjust the height of the lifting tools according to actual needs during the lifting process, making it difficult to adapt to the lifting requirements of different heights and angles. This limitation not only affects the efficiency of the lifting operation, but also reduces the safety of the construction to a certain extent. Utility Model Content

[0039] The working principle of the above embodiment is:

[0040] When turning, the adjusting motor 3 is started first, and the adjusting motor 3 then drives the transmission rod 4 to rotate, the transmission rod 4 then drives the transmission gear 5 to rotate, the transmission gear 5 then drives the driven gear 6 meshing therewith to rotate, the driven gear 6 then drives the rotating rod 7 to rotate, the rotating rod 7 then drives the rotating disk 8 to rotate, the rotating disk 8 then drives the frame 9 to rotate, thereby realizing the turning of the lifting tool;
