The lower end of the anchor rod penetrates into the upper connecting base piece and is fixed through a nut, and the upper end of the anchor rod is connected with a main truss system corresponding to the hanging basket. The utility model provides a bidirectional hinging lifting lug adapter for a rear fulcrum hanging basket cross beam of an ultra-wide and variable-width PC cable-stayed bridge. The structural design of the two-way hinged lifting lug adapter can bear large pressure and impact force, and can be used in a high-load working environment. The bidirectional hinged lifting lug adapter can release longitudinal and transverse bending moments of the end part of the lifting rod, so that the lifting rod is only subjected to axial force, the stress of the lifting rod is clear, and the whole structure is safer and more reliable.

Description

Technical Field

[0001] The utility model relates to the field of cable-stayed bridge construction, in particular to a bidirectional hinged lifting lug adapter for a rear support hanging basket crossbeam of an ultra-wide variable-width PC cable-stayed bridge. Background Art

[0002] Currently in operation;

[0003] 1. Conventional hanging eye adapters for hanging baskets are all one-way hinged to release the longitudinal bending moment at the end of the hanging eye. However, when transverse bending moment, pressure and impact load need to be considered, the one-way hinged hanging eye adapter is no longer applicable.

[0004] 2. Due to the large lateral rigidity of the one-way hinge, it may not be able to adapt to the changes in external force and vibration absorption, and it is difficult to withstand large deformation. The response to external force is also very fast, so once it receives excessive external force, it may collapse instantly. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a bidirectional hinged lifting lug adapter for the rear support basket crossbeam of an ultra-wide variable-width PC cable-stayed bridge. The structural design of the bidirectional hinged lifting lug adapter can withstand greater pressure and impact force and can be used in high-load working environments. The bidirectional hinged lifting lug adapter can release the longitudinal and transverse bending moments at the end of the suspension rod, so that the suspension rod is only subjected to axial force, which clarifies the force of the suspension rod and makes the overall structure safer and more reliable.

[0006] The utility model is implemented by constructing a bidirectional hinged lifting lug adapter (10) for a rear support hanging basket cross beam of an ultra-wide variable-width PC cable-stayed bridge, characterized in that the lifting lug adapter (10) comprises a lower connecting seat (1) for connecting with the rear lower cross beam of a bottom basket system, and also comprises a connecting member (2), wherein the connecting member (2) and the lower connecting seat (1) are connected via a first pin shaft (3), and also comprises an upper connecting seat member (4), wherein the upper connecting seat member (4) and the connecting member (2) are connected via a second pin shaft (5), and also comprises an anchor rod (6), wherein the lower end of the anchor rod (6) penetrates into the upper connecting seat member (4) and is fixed via a nut, and the upper end of the anchor rod (6) is connected to the main truss system corresponding to the hanging basket.

[0007] The utility model has the advantages:

[0008] 1. The structural design of the two-way hinged lifting eye adapter can withstand greater pressure and impact force and can be used in high-load working environments.

[0009] 2. The two-way hinged lifting lug adapter can release the longitudinal and transverse bending moments at the end of the boom, so that the boom is only subjected to axial force, which clarifies the force on the boom and makes the overall structure safer and more reliable.
