Description

Technical Field

[0001] This utility model relates to the field of bridge hangers, and in particular to a bridge hanger assembly. Background Technology

[0002] Bridge suspenders, as key load-bearing components in long-span bridge structures such as suspension bridges and cable-stayed bridges, bear the core function of transferring bridge deck loads to the main cable or main tower. Their technical performance directly affects the safety, durability, and economy of the bridge. Traditional suspenders mostly adopt a structure of parallel steel wire bundles or steel strands wrapped with high-density polyethylene sheaths, connected to the bridge deck and main cable / main tower through anchors. The design must comprehensively consider key indicators such as fatigue strength, corrosion protection, and dynamic response. As bridge spans continue to increase, suspenders need to withstand higher axial tensile forces and complex environmental coupling effects, prompting the industry to evolve towards high-strength materials, intelligent monitoring, and lightweight design. For example, zinc-aluminum alloy coated steel wire is used to improve corrosion resistance, or fiber optic grating sensors are integrated to achieve real-time stress monitoring.

[0003] Modern bridge suspender technology is undergoing a transformation from passive maintenance to proactive prevention, with innovation focusing on the cross-integration of materials science, manufacturing processes, and digital technologies. At the materials level, the application of ultra-pure precision-rolled threaded steel bars and carbon fiber reinforced polymer (CFRP) composites significantly improves the tensile strength and fatigue life of suspenders while reducing structural weight. In terms of manufacturing processes, automated bundling technology and vacuum-assisted grouting ensure uniform stress distribution on the wire bundles and the density of the sheath, effectively delaying the penetration of corrosive media. Meanwhile, IoT-based intelligent suspender systems collect strain, temperature, and vibration data through built-in sensor networks, combining machine learning algorithms to achieve damage localization and remaining life prediction, providing data support for the full lifecycle management of bridges. These technological breakthroughs not only extend the service life of suspenders but also drive the development of bridge structures towards greater safety and intelligence.

[0004] Patent document CN221798131U discloses a bridge suspender hinge support, comprising several sets of suspenders, each set of suspenders connected to a hinge support; the suspenders are provided with a connecting mechanism for connecting a counterweight unit, the connecting mechanism being located above the hinge support; a mutual support mechanism for supporting the two sets of steel cables is provided between two corresponding sets of steel cables; the mutual support mechanism includes a support seat, the connecting mechanism includes a connecting seat, and a locking mechanism for fixing the connecting seat and the support seat is provided between the support seat and the connecting seat; this solves the technical problem of low hoisting efficiency due to the large amount of time required when installing stiffening beams.

[0005] As in the prior art of the aforementioned patent, the suspension rod is installed using a single rod and a single support. However, this installation structure is similar to a simple suspension system, relying solely on a single rod for support. Once the suspension rod breaks, deforms excessively, or fails in connection, the entire load-bearing system collapses immediately, lacking a backup load-bearing path and exhibiting extremely low safety. Its installation requires strict assurance of the perpendicularity and coaxiality of the suspension rod and the support; even minor deviations can lead to stress concentration and accelerate fatigue damage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A bridge suspension rod assembly includes a first connecting rod 1 and a second connecting rod 2. A first frame 3 and a second frame 4 are fixedly welded to the bottom ends of the first connecting rod 1 and the second connecting rod 2, respectively. A first insertion groove 13 and a second insertion groove 14 are respectively formed on the first connecting rod 1 and the second connecting rod 2. A first mounting component 10 is fixedly welded to the top end of the first frame 3, and a second mounting component 11 is welded to the top end of the second frame 4. The second frame 4 and the second mounting component 11 are double-layered plates with internal cavities. The first frame 3 and the second frame 4 are interlocked and welded together, and the first mounting component 10 and the second mounting component 11 are mutually... The first mounting component 10 and the second mounting component 11 are both provided with connecting holes 12. A first hanger 5 and a second hanger 6 are respectively provided at the connecting holes 12. The other ends of the first hanger 5 and the second hanger 6 are respectively connected to the arched frame 9. The bottom of the two hangers are respectively connected to a point, and the tops of the two hangers are respectively supported at two positions on the arched frame 9. On the one hand, it can save the bottom installation space, and on the other hand, it can reduce the tension of a single hanger in the vertical direction. By distributing the load through the two hangers, in addition to bearing the tension from the vertical direction, it can also withstand the force in the horizontal direction, which increases the wind resistance and lateral stability.

[0025] It is worth noting that the connection between the first connecting rod 1, the second connecting rod 2, and the two mounting components is prior art. The connecting rods and mounting components are not the main support structure of the bridge body, but rather the railing components above the bridge body. Furthermore, the installation and connection methods are all prior art. Since the object to be protected by this utility model is the hanging rod assembly, other unrelated technical features will not be described in detail.

[0026] As a preferred technical solution in this embodiment, the bottom ends of the first lifting rod 5 and the second lifting rod 6 are respectively fixedly installed with a first leaf spring lug 15 and a second leaf spring lug 16. The first leaf spring lug 15, the second leaf spring lug 16 and the multiple connecting holes 12 are locked to each other by a third anchor bolt 22. One side of the first leaf spring lug 15 overlaps with the first mounting member 10, and the other side of the first leaf spring lug 15 abuts against the second leaf spring lug 16. In addition to abutting against each other, the two leaf spring lugs also abut against the first mounting member 10 and the second mounting member 11 on both sides at the connection point, which increases the stability of the installation and the structural rigidity.

[0027] As a preferred technical solution of this embodiment, a single-hole lifting lug 26 is fixedly installed at the top of the first lifting rod 5, and a first hanging member 7 is provided between the first lifting rod 5 and the arched frame 9. The first hanging member 7 is hung on the arched frame 9 and welded to it. The single-hole lifting lug 26 and the first hanging member 7 are locked together by a fourth anchor bolt 23. The first lifting rod 5 is fixedly connected to the arched frame 9 through the first hanging member 7. The setting of the first hanging member 7 can evenly distribute the tension to the arched frame 9.

[0028] As a preferred technical solution in this embodiment, a plug plate 19 is welded to the top of the second rod 6, and a second anchor bolt 20 is threaded on the plug plate 19.

[0029] As a preferred technical solution in this embodiment, the arched frame 9 is a double-layer design. A fixing member 24 is fixedly installed inside the arched frame 9. The fixing member 24 is fixedly connected to the second hanging member 8 set on the arched frame 9. An installation plate 25 is provided at the bottom end of the fixing member 24. A first anchor bolt 17 is threaded on the installation plate 25. The installation plate 25 is fixedly connected to the fixing member 24 through the first anchor bolt 17. An insertion hole 18 is opened on the installation plate 25. An insertion member 21 is opened at the bottom end of the insertion plate 19. The insertion member 21 and the insertion hole 18 are mutually compatible. Since the verticality of the second hanger 6 is high, its vertical bearing capacity also needs to be strong. The stability between the second hanger 6 and the arched frame 9 can be increased by the second hanging member 8 and the insertion plate 19.

[0030] As a preferred technical solution in this embodiment, threaded holes 27 are provided on both sides of the arched frame 9, and the plug-in plate 19 is fixedly connected to the arched frame 9 through the second anchor bolt 20 and the threaded holes 27; the plug-in plate 19 can be fixed on the second hanging frame and the arched frame 9 through the second anchor bolt 20.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
