Description

Technical Field

[0001] The utility model relates to a cable clamp of a suspension bridge, in particular to a cable clamp bolt protection structure. Background Art

[0002] In suspension bridge structures, the cable clamp is a critical load-bearing component connecting the bridge deck to the main cable. Locked by multiple sets of connecting bolts, it encircles the main cable and endures long periods of outdoor service in harsh working conditions, subjecting it to the elements. To prevent the elements from corroding the bolts and ensure their long-term service life, a protective cover is attached to the end of the bolt where it extends beyond the platform supporting the cable clamp. This cover isolates and seals the corresponding end of the bolt from the outside world.

[0003] Currently, the protective covers used in the industry are directly connected to the corresponding ends of the connecting bolts using a threaded structure. For example, Chinese patent documents such as "A Sealing and Protective Device for Suspension Bridge Cable Clamp Bolts," Publication No. CN 209260559U, Publication Date: August 16, 2019, and "Sealing Device for Cable Clamp Screw," Publication No. CN111609135 A, Publication Date: September 1, 2020, are disclosed. These technologies employ an internal threaded structure within the protective cover, which is then threadedly connected to the corresponding ends of the connecting bolts. The open end of the protective cover abuts the corresponding receiving platform of the cable clamp half to achieve a sealed connection between the connecting bolts. However, the mating relationship between the protective cover and the connecting bolt in these technologies increases the technical difficulty of manufacturing the protective cover and attaching the protective cover to the cable clamp. Furthermore, due to the limitations of the threaded connection, the open end of the protective cover struggles to seal against the corresponding receiving platform, resulting in an unstable sealing effect. Utility Model Content

[0004] The technical purpose of the utility model is to provide a cable clamp bolt protection structure with simple structure, easy installation and good sealing effect in view of the particularity of the cable clamp protection of the above-mentioned suspension bridge and the shortcomings of the existing technology.

[0005] The technical purpose of the utility model is achieved through the following technical solutions: a cable clamp locking bolt protection structure, comprising a plurality of cable clamp halves circumferentially locked together by a plurality of sets of locking bolts;

[0006] A protective cover is connected to the receiving platform of each cable clamp half, which seals and isolates the end of the corresponding locking bolt from the outside world;

[0007] The protective cover has a protective cavity for accommodating the end of the corresponding locking bolt in a non-contact manner, and the open end of the protective cavity has a folded-out joint bottom edge;

[0008] The protective cover is buckled on the receiving platform of the corresponding cable clamp half, covering the corresponding locking bolt end in a non-contact manner, and the combined bottom edge of the protective cover is fixed to the receiving platform by multiple connecting screws.

[0009] The protective cover of the above technical measures accommodates the corresponding locking bolt end in a non-contact manner and is fixed with connecting screws. It has a simple structure, is easy to manufacture, and is easy to install. The open end of the protective cover with a non-contact design fits more tightly on the corresponding receiving platform, which can effectively prevent the entry of external corrosive substances and has a good sealing effect.

[0010] The protective cover, fixed to the cable clamp half-body receiving platform by multiple connecting screws, has a flexible sealing structure between the bottom edge and the receiving platform. The cable clamp bolt protection structure of this technical measure has a flexible sealing structure between the bottom edge of the protective cover and the receiving platform, which enhances the sealing effect and effectively prevents the ingress of external corrosive substances.

[0011] The bottom edge of the protective cover has a sealing groove with an inward concave structure, and an O-ring is embedded in the sealing groove;

[0012] The protective cover is fixed to the cable clamp half-body receiving platform through a plurality of connecting screws, and is combined with the bottom edge to form a flexible seal between the O-shaped sealing ring and the receiving platform.

[0013] The O-ring is embedded in the sealing groove of the cable clamp bolt protection structure of the above technical measures, which can effectively fill the gap between the bottom edge of the joint and the receiving platform, and has a good sealing effect.

[0014] The sealing groove of the joint bottom edge is formed inside the connecting screw connected to the joint bottom edge and is spaced apart from the connecting screw. The sealing groove of the cable clamp bolt protection structure of this technical measure is located inside the connecting screw and is spaced apart, which improves the sealing performance of the protective cover, can better exert the sealing function, and has good sealing performance.

[0015] The ends of each locking bolt on the cable clamp half-body receiving platform are respectively provided with a protective cover.

[0016] The top profile of the protective cover is a circular structure or a polygonal structure.

[0017] Alternatively, the ends of the multiple locking bolts on the cable clamp half-body receiving platform are jointly equipped with a same protective cover.

[0018] The top profile of the protective cover is a waist-shaped structure or a rectangular structure.

[0019] The beneficial technical effect of the utility model is that the protective cover of the utility model accommodates the corresponding locking bolt end in a non-contact manner and is fixed with connecting screws. It has a simple structure, is easy to manufacture, and is easy to install. The opening end of the protective cover with a non-contact design fits more tightly on the corresponding receiving platform, which can effectively prevent external corrosive substances from entering and has a good sealing effect.

[0033] Example 3

[0034] The utility model provides a cable clamp locking bolt protection structure comprising two cable clamp halves circumferentially locked together by two sets of locking bolts. Each cable clamp half is an arcuate semi-ring structure, with its circumferentially abutting ends each having a radially outwardly convex receiving platform. The two cable clamp halves circumferentially abut against the corresponding receiving platforms to form a cable hole. Two sets of locking bolts are positioned at each abutting receiving platform of the two cable clamp halves, locking the receiving platforms at these abutting locations. Each set of locking bolts comprises multiple bolts arranged at intervals.

The top profile of the protective cover is a long waist-shaped structure, which can accommodate the ends of multiple adjacent locking bolts.

[0036] The protective cover comprises a protective cavity for non-contact accommodation of the end of the corresponding locking bolt, and a folded-out bottom edge at the open end of the protective cavity. The protective cover is buckled onto the receiving platform of the corresponding cable clamp half, non-contactly enclosing the end of the corresponding locking bolt. The bottom edge of the protective cover is secured to the receiving platform via a plurality of connecting screws.

[0037] A flexible sealing structure is provided between the protective cover, the bottom edge, and the receiving platform. Specifically, the bottom edge of the protective cover has a concave sealing groove. This groove is formed on the bottom edge, inboard of the connecting screws to which the bottom edge is connected, and is spaced to mate with the screws. An O-ring is embedded in the sealing groove of the bottom edge. The protective cover is fixed to the corresponding receiving platform via multiple connecting screws, and the O-ring forms a flexible seal between the bottom edge and the receiving platform.
