Background
In the suspension bridge engineering, dynamic and static loads of a bridge act on a main cable, and the main cable is a core bearing member of the suspension bridge and is known as a 'life line' of the suspension bridge. Therefore, the service safety performance of the main cable directly plays a role in the service safety of the whole suspension bridge.
In order to reduce the erosion of the main cable by natural factors in the atmosphere, the outer part of the main cable is provided with a protection structure, the protection structure mainly comprises a winding protection structure wound on the outer part of a main cable section with a circular cross section and a cable sleeve structure sleeved on the outer part of a main cable section with a special-shaped cross section (namely a scattered transition section), the cable sleeve structure is mainly arranged at the position of a main cable outgoing and incoming cable saddle cover or an anchor chamber front wall, on one hand, the main cable at the position of the main cable outgoing and incoming cable saddle cover or the anchor chamber front wall is irregularly scattered in cross section and is unfavorable for winding protection, and the cable sleeve capable of surrounding the main cable is required to be protected, on the other hand, the protection structure is suitable for load change born by the main cable, displacement telescopic movement is allowed to be generated at the position of the main cable outgoing and incoming cable saddle cover or the anchor chamber front wall, and compared with the cable sleeve structure, the constraint of the cable sleeve structure on the main cable is small, so that the load change born by the main cable is not influenced by the protection structure.

In this technique, the corresponding end portion of the cable sheath body is connected to the opposite structural member through the corrugated axial deformation tube, and large-displacement expansion and contraction are realized by expansion and contraction deformation of the corrugated axial deformation tube. The technology can generate larger displacement expansion deformation in the axial direction, but is mainly formed by combining axial deformation pipes at two ends and a cable sleeve body with a rigid structure, so that the whole molding structure is complex, the manufacturing and assembling processes are troublesome, and the whole weight under the action of the cable sleeve body with the rigid structure is heavy.

More specifically, before the cable cover suit, when the main cable is erect, the cable saddle cover department is fixed with the transition section of thick bamboo with bolted connection mode, and this transition section of thick bamboo is the relative structure of corresponding rubber cable cover body major diameter end in the suspension bridge structure promptly. The transition cylinder is used for being matched with the end part of the large-diameter end of the rubber cable sleeve body and is provided with a fixing flange which is folded outwards in the radial direction, and a plurality of bolt perforations are distributed on a ring Zhou Jianju of the fixing flange.
The large-diameter end of the rubber cable sleeve body is provided with a cable sleeve side flange plate which is formed by turning over radially outwards. Based on the circumferential opening structure of the rubber cable sleeve body, the circumference of the flange plate at the side of the cable sleeve is of a non-closed structure. And a plurality of bolt perforations which can be matched with the bolt perforations on the fixed flange plate in a one-to-one correspondence manner are distributed at intervals on the periphery of the flange plate at the side of the cable sleeve. The cable sleeve side flange plate of the rubber cable sleeve body is axially butted on the fixed flange plate of the transition cylinder, under the condition that the circumference of the rubber cable sleeve body is closed, bolt perforation holes on the cable sleeve side flange plate and bolt perforation holes on the fixed flange plate form one-to-one correspondence matching, and a compression ring is sleeved on the rubber cable sleeve body on one side of the cable sleeve side flange plate, which is opposite to the fixed flange plate. The clamp ring is used for locking and stressing the connecting bolts, so that the clamp ring preferably adopts a circumferential butt joint structure of an upper half and a lower half, and the circumferential butt joint parts do not need to form rigid connection. Thus, the fixing flange, the cable sleeve side flange and the clamp ring which are axially and sequentially butted are fixedly connected through a plurality of connecting bolts distributed by the rings Zhou Jianju to form a flange clamping structure, namely a flange assembly, and the cable sleeve side flange is clamped in the middle by the fixing flange and the clamp ring.
In order to realize the assembly connection with the circular cross section of the main cable, the small diameter end of the rubber cable sleeve body is hooped and fixed on the main cable by a hoop clamping structure.
More specifically, the small diameter end of the rubber cable sleeve body is provided with a straight cylinder structure which extends axially and is matched with the circular cross section of the main cable, and the straight cylinder section of the small diameter end of the rubber cable sleeve body is hooped and fixed on the main cable through the hoop component.
The hoop assembly is formed by butt joint and combination of a tile ring half body I and a tile ring half body II at the periphery. The two ends of the circumference of the tile ring half body I are respectively provided with a butt joint lug I which is formed in a protruding mode, and a plurality of bolt through holes are formed in the butt joint lug I at intervals. Two ends of the circumference of the tile ring half body II are respectively provided with a butt joint lug II which is formed in a protruding mode, a plurality of bolt through holes are formed in the butt joint lug II at intervals, and each bolt through hole in the butt joint lug II on the same side is in one-to-one corresponding matching relation with each bolt through hole in the butt joint lug I. The tile ring half body I and the tile ring half body II of the main cable outer ring Zhou Duijie are connected by a plurality of bolts which are penetrated in the butt joint lug I and the butt joint lug II which are matched on the same side. In order to provide enough clamping pretightening force for the straight barrel section of the rubber cable sleeve body, a sufficient locking force application space is reserved between the tile ring half body I and the tile ring half body II in the circumferential abutting structure, namely, under an unlocked initial state, a matching gap for locking force application exists between the tile ring half body I and the tile ring half body II in circumferential abutting.
