Description

Technical Field

[0001] The utility model relates to a protective cable sleeve for a main cable of a suspension bridge, in particular to a rubber cable sleeve for protecting the main cable of a suspension bridge. Background Art

[0002] In suspension bridge projects, the dynamic and static loads of the bridge act on the main cable, which is the core load-bearing component of the suspension bridge and is known as the "lifeline" of the suspension bridge. It can be seen that the service safety performance of the main cable is directly related to the service safety of the entire suspension bridge.

[0003] In order to reduce the erosion of the main cable by natural factors in the atmospheric environment, the main cable is provided with a protective structure on the outside. The protective structure is mainly composed of a wire-wrapped protective structure wrapped around the outside of the main cable section with a circular cross-section, and a cable sleeve structure wrapped around the outside of the main cable section with a special cross-section (i.e., a dispersed transition section). The cable sleeve structure is mainly arranged at the main cable inlet and outlet saddles or at the front wall of the anchor chamber. On the one hand, because the main cable at the outlet and outlet saddles or at the front wall of the anchor chamber has an irregular and dispersed cross-section, it is not conducive to wire-wrapped protection, and a cable sleeve that can cover it is required for protection; on the other hand, in order to adapt to the load changes on the main cable, the protective structure is allowed to produce displacement and expansion activities at the outlet and outlet saddles or at the front wall of the anchor chamber. Compared with the wire-wrapped structure, the cable sleeve structure has less constraint on the main cable, so that the load changes on the main cable are not affected by the protective structure.

[0004] The traditional cable sleeve structure is mainly composed of a rigid structure upper half and a lower half of the cable sleeve which are circumferentially locked by locking bolts. When installed on the main cable, the two ends are connected to the corresponding structural parts by a sealing rubber ring. Its displacement and expansion are completely dependent on the compression deformation capacity of the sealing rubber ring. The displacement and expansion deformation is small and cannot meet the large displacement and expansion under large loads.

[0005] In view of this, the applicant previously disclosed a cable sleeve capable of realizing large displacement expansion and contraction, as detailed in the Chinese patent document entitled "A cable sleeve for main cables of a suspension bridge capable of realizing large displacement expansion and contraction" (publication number CN 205822011 U, publication date December 21, 2016). In this technology, the corresponding ends of the cable sleeve body are connected to the relative structural members through an axial deformation tube of a corrugated structure, and large displacement expansion and contraction is realized through the expansion and contraction deformation of the axial deformation tube of the corrugated structure. Although this technology can produce large displacement expansion and contraction deformation in the axial direction, it is mainly composed of the axial deformation tubes at both ends and the cable sleeve body of the rigid structure, which makes the overall molding structure complex, the manufacturing and assembly process troublesome, and the overall weight is heavy under the action of the cable sleeve body of the rigid structure.

[0006] The applicant also disclosed a cable sleeve with a simple structure and light weight earlier, as detailed in the Chinese patent document entitled "Polyurethane cable sleeve for main cable of suspension bridge" (publication number CN 205822010 U, publication date December 21, 2016). In this technology, the cable sleeve body is molded with polyurethane with a simple structure and light weight. However, its expansion and deformation displacement only depends on the polyurethane material itself, and the expansion and deformation displacement range is limited, which cannot meet the large displacement expansion and contraction under large load.

[0007] Therefore, in order to adapt to the particularity of main cable protection of suspension bridges and achieve large displacement and expansion with a simple and lightweight structure, it is necessary to develop a new cable sleeve structure. Utility Model Content

[0008] The technical purpose of the utility model is to provide a rubber cable sleeve for protecting the main cable of a suspension bridge, which has a simple and light structure and can achieve large displacement and telescopic properties, in view of the particularity of the main cable protection of the above-mentioned suspension bridge and the shortcomings of the existing technology.

[0009] The technical purpose of the utility model is achieved through the following technical solution: a rubber cable sleeve for protecting the main cable of a suspension bridge. In the suspension bridge structure, the rubber cable sleeve is sleeved on the dispersed transition section of the main cable. The rubber cable sleeve has a large-diameter end corresponding to the dispersed end of the dispersed transition section of the main cable, and has a small-diameter end corresponding to the concentrated end of the dispersed transition section of the main cable;

[0010] The rubber cable sleeve has a rubber cable sleeve body formed of rubber material and having an axial bellows structure;

[0011] The large diameter end of the rubber cable sleeve body is assembled and connected with the relative structure by a flange clamping structure;

[0012] The small diameter end of the rubber cable sleeve body is assembled and connected with the relative structure by means of a flange clamping structure, or the small diameter end of the rubber cable sleeve body is clamped and fixed on the main cable by means of a clamp clamping structure.

[0013] The above technical measures aim at the particularity of the main cable protection of the suspension bridge, and the cable sleeve is formed with a rubber material with a lighter structure and better scalability, and the rubber cable sleeve body is an axially scalable bellows structure, so that it has a large displacement and deformation range, and can achieve large axial displacement and deformation, effectively meeting the large displacement and expansion under large load. Therefore, the cable sleeve of the above technical measures has the technical characteristics of simple and lightweight molding structure and can achieve large displacement expansion.

[0014] As one of the preferred solutions, the rubber cable sleeve body is a circumferentially open structure on one side, and has an opening for enclosing the main cable;

[0015] The edges of both sides of the opening are connected with zipper components that can close the rubber cable sleeve body around its periphery;

[0016] Furthermore, the two toothed belts of the zipper assembly are fixedly connected to the corresponding edges on both sides of the opening of the rubber cable sleeve body along the axial corrugated track of the rubber cable sleeve body.

[0017] The rubber cable sleeve body of the above technical measures is realized in a C-shaped wrapping structure when assembled on the main cable, which is easy and convenient to install and does not affect the divergence of the main cable. Compared with the cylinder structure, it can be easily installed after the main cable is arranged; compared with the existing split assembly structure, the rubber cable sleeve body after C-shaped wrapping can be easily closed on the main cable with a zipper assembly structure. And the existence of the zipper assembly will not affect the expansion and contraction deformation of the rubber cable sleeve body along the circumferential corrugated structure.

[0018] Furthermore, an adhesive lining tape is fixedly connected to one side of the opening of the rubber cable sleeve body, and the adhesive lining tape extends outward from the side where the opening is located;

[0019] When the opening of the rubber cable sleeve body is closed, the adhesive lining tape is laid at the opening and is adhesively matched with the opposite side.

[0020] The rubber cable sleeve body of the above technical measures is sealed with the backing of the adhesive lining tape, thereby strengthening the circumferential closing effect of the rubber cable sleeve body and reducing the intrusion of external corrosive substances into the cable sleeve through the zipper assembly.

[0021] Furthermore, the extension of the adhesive lining tape forms a bifurcated arrangement structure with the toothed belt of the zipper assembly on the side in the thickness direction. This technical measure is conducive to the operation of the zipper assembly, and the adhesive lining tape basically does not cause position interference to the operation of the zipper assembly.

[0022] As one of the preferred solutions, the rubber cable sleeve body is an EPDM rubber molding structure. The rubber cable sleeve body of this technical measure has the technical characteristics of good telescopic deformation effect, heat resistance, corrosion resistance, aging resistance and the like.

[0023] As one of the preferred solutions, the large diameter end of the rubber cable sleeve body is provided with a cable sleeve side flange folded outward;

[0024] Correspondingly, the large diameter end of the rubber cable sleeve body has a fixed flange plate folded outward on the corresponding relative structure in the suspension bridge structure;

[0025] The cable sleeve side flange of the rubber cable sleeve body is axially butted against the fixed flange of the relative structure, and a clamping ring is mounted on the side of the cable sleeve side flange opposite to the fixed flange. The fixed flange, cable sleeve side flange and clamping ring, which are axially butted in sequence, are fixedly connected by multiple connecting bolts arranged at circumferential intervals to form a flange clamping structure.

[0026] Furthermore, the relative structure corresponding to the large diameter end of the rubber cable sleeve body in the suspension bridge structure is a pre-buried tube;

[0027] The embedded tube is used to cooperate with the end of the large diameter end of the rubber cable sleeve body and has an embedded side flange that is folded outward to form a fixed flange.

[0028] The above technical measures are aimed at the particularity of the main cable divergent structure. The rubber cable sleeve body is assembled on the relative structure with a flange assembly. Through the docking combination of the flange assembly, it can ensure that the rubber cable sleeve body is stably and reliably assembled and fixed at the divergence of the main cable, with good fixing effect and easy operation.

[0029] As one of the preferred solutions, the small diameter end of the rubber cable sleeve body is a straight tube structure matching the main cable body;

[0030] The small diameter end of the rubber cable sleeve body is clamped and fixed on the main cable through a clamp assembly.

[0031] The above technical measures are aimed at the particularity of the main cable divergent structure. A straight tube structure is formed at the small diameter end of the rubber cable sleeve body, and the straight tube structure at the small diameter end of the rubber cable sleeve body is directly clamped and fixed on the main cable by a clamp assembly, thereby forming a stable and reliable assembly and fixation on the main cable, with good fixing effect and easy operation.

[0032] Furthermore, the hoop assembly is formed by circumferentially butting the first and second half-pieces of the tile ring together;

[0033] The two ends of the circumference of the tile ring half body are respectively provided with outwardly convex docking ears;

[0034] The two ends of the circumference of the second tile ring half body are respectively provided with two outwardly convex docking ears;

[0035] The circumferentially butted tile ring half body one and the circumferentially butted tile ring half body two are connected by a combination of multiple bolts inserted into the matching butt ears one and two on the same side.

[0036] The clamp assembly of the above technical measures has the technical characteristics of simple structure and stable force, so that the straight tube structure of the small diameter end of the rubber cable sleeve body can be reliably clamped and fixed on the main cable, so that the small diameter end of the rubber cable sleeve body is stably and reliably assembled and fixed on the main cable.

[0037] The beneficial technical effect of the utility model is as follows: the above technical measures are aimed at the particularity of the protection of the main cable of the suspension bridge, and the cable sleeve is molded with a rubber material with a lighter structure and better elasticity, and the molded rubber cable sleeve body is an axially elastic and deformable bellows structure, so that its displacement and deformation range is large, and large axial displacement and deformation can be achieved, which effectively meets the large displacement expansion and contraction under large loads, and has the technical characteristics of simple and lightweight molding structure and large displacement expansion and contraction.

DETAILED DESCRIPTION

[0046] The utility model relates to a protective cable sleeve for the main cable of a suspension bridge, specifically a rubber cable sleeve for protecting the main cable of a suspension bridge. The main technical solution of the utility model is specifically described below in combination with multiple embodiments. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The technical solution of the present utility model is clearly and in detail explained; although other embodiments are not separately drawn with drawings, their main structures can still refer to the drawings of embodiment 1.

[0047] It should be noted that the drawings of the present invention are schematic, and unnecessary details have been simplified to clarify the technical purpose of the present invention, so as to avoid blurring the technical solution of the present invention in the prior art. In addition, the expressions "approximately" and "substantially" in the following text regarding quantity or matching relationship mean that reasonable assembly errors and processing errors in the industry are allowed to exist, and do not literally express absolute quantity or matching relationship.

[0048] Example 1

[0049] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the utility model is a rubber cable sleeve for protecting the main cable of a suspension bridge. In the suspension bridge structure, the rubber cable sleeve is sleeved on the dispersed transition section of the main cable 5, so the rubber cable sleeve has a large diameter end corresponding to the dispersed end of the dispersed transition section of the main cable 5 (for example, at the saddle cover of the cable saddle or the front wall of the anchor chamber, and the front wall of the anchor chamber is taken as an example below), and a small diameter end corresponding to the concentrated end of the dispersed transition section of the main cable 5 (for example, a main cable section with a circular cross section or near a cable clamp, and the main cable section with a circular cross section is taken as an example below). The outer contour of the entire rubber cable sleeve is a tapered cylindrical structure.

[0050] The rubber cable sleeve of the utility model comprises a rubber cable sleeve body 1 formed of EPDM rubber and having a bellows structure arranged at intervals along the axial length. The rubber cable sleeve body 1 is a structure with one side opening around the circumference, and in a non-closed loop state, the end face profile is in a C-shape tending to be closed, thereby forming an opening 13 formed along the axial length around the circumference to enclose the main cable 5.

[0051] More specifically, in order to enable the rubber cable cover body 1 to be closed in the circumferential direction, two toothed belts of the zipper assembly 12 are connected to the edges of the opening 13 of the rubber cable cover body 1 by tying wires or hot-melt bonding, and the rubber cable cover body 1 can be closed in the circumferential direction by the zipper assembly 12 to form a cylindrical structure. The two toothed belts of the zipper assembly 12 are fixedly connected to the corresponding edges of the opening 13 of the rubber cable cover body 1 along the axial corrugated track of the rubber cable cover body 1, that is, the toothed belts of the zipper assembly 12 form a corrugated arrangement structure on the rubber cable cover body 1 along the length direction.

[0052] In order to seal the zipper assembly 12 at the opening 13 of the rubber cable cover body 1, a bonding tape 11 formed of EPDM rubber and having a corrugated structure along the length direction is fixed to the inner side of the edge of one side of the opening 13 by hot-melt bonding. The bonding tape 11 extends outward from the side where the opening 13 is located. In order to prevent the bonding tape 11 from affecting the opening / closing pulling action of the zipper assembly 12, the extended part of the bonding tape 11 should form a Y-shaped forked arrangement structure with the toothed belt of the zipper assembly 12 on the side in the thickness direction of the rubber cable cover body 1. The outer surface of the area where the bonding tape 11 extends from the side is used to bond with the inner wall of the other side of the opening 13, so an adhesive layer is prefabricated during bonding or in advance, that is, when the opening 13 of the rubber cable cover body 1 is closed, the bonding tape 11 should be laid on the inner side of the opening 13 and form a bonding match with the opposite side.

[0053] In order to realize the assembly connection with the front wall of the anchor chamber, the large diameter end of the rubber cable sleeve body 1 is assembled and connected with the relative structure by means of a flange clamping structure.

[0054] More specifically, before the cable sleeve is installed and when the main cable is erected, a pre-embedded tube 3 is anchored at the front wall of the anchor chamber, that is, the pre-embedded tube 3 is a relative structure corresponding to the large diameter end of the rubber cable sleeve body 1 in the suspension bridge structure. The pre-embedded tube 3 is used to cooperate with the end of the large diameter end of the rubber cable sleeve body 1, and has a pre-embedded side flange 21 that is radially folded outward to form a fixed flange. The pre-embedded side flange 21 is arranged with a plurality of bolt through holes at circumferential intervals.

[0055] At the large diameter end of the rubber cable sleeve body 1, there is a cable sleeve side flange 22 which is folded radially outward. Based on the circumferential opening structure of the rubber cable sleeve body 1, the circumference of the cable sleeve side flange 22 is a non-closed structure. Around the circumference of the cable sleeve side flange 22, a plurality of bolt through holes are arranged at intervals, which can form a one-to-one correspondence with the bolt through holes on the above-mentioned embedded side flange 21. The cable sleeve side flange 22 of the rubber cable sleeve body 1 is axially docked on the embedded side flange 21 of the embedded tube 3. When the rubber cable sleeve body 1 is in a closed state around the circumference, the bolt through holes on the cable sleeve side flange 22 form a one-to-one correspondence with the bolt through holes on the embedded side flange 21. Moreover, a clamping ring 23 is mounted on the rubber cable sleeve body 1 on the side of the cable sleeve side flange 22 opposite to the embedded side flange 21. The clamping ring 23 is used to lock the connection bolts 24 described below, so the clamping ring 23 preferably adopts a circumferential butt joint structure with upper and lower halves, and a rigid connection is not required at the circumferential butt joint. In this way, the embedded side flange 21, the cable sleeve side flange 22 and the clamping ring 23, which are axially butt jointed in sequence, are fixedly connected by a plurality of connection bolts 24 arranged at circumferential intervals to form a flange clamping structure, i.e., a flange assembly 2, and the cable sleeve side flange 22 is clamped in the middle by the embedded side flange 21 and the clamping ring 23.

[0056] In order to realize the assembly connection with the circular cross-section section of the main cable, the small diameter end of the rubber cable sleeve body 1 is clamped and fixed on the main cable 5 by a clamping structure.

[0057] More specifically, the small diameter end of the rubber cable sleeve body 1 has an axially extending straight tube structure that matches the circular cross-section section of the main cable 5 . The straight tube section of the small diameter end of the rubber cable sleeve body 1 is clamped and fixed on the main cable 5 by the clamp assembly 4 .

[0058] The clamp assembly 4 is formed by the circumferential butt joint combination of the first half of the ring 41 and the second half of the ring 42. The first half of the ring 41 has a butt joint ear 43 formed outwardly at both ends of the circumference, and a plurality of bolt through holes are provided at intervals on the butt joint ear 43. The second half of the ring 42 has a butt joint ear 44 formed outwardly at both ends of the circumference, and a plurality of bolt through holes are provided at intervals on the butt joint ear 44, and each bolt through hole on the butt joint ear 44 on the same side is in a one-to-one corresponding relationship with each bolt through hole on the butt joint ear 43. The first half of the ring 41 and the second half of the ring 42, which are butt jointed on the outside of the main cable 5, are connected by a plurality of bolts installed in the butt joint ear 43 and the butt joint ear 44 on the same side. In order to provide sufficient clamping pre-tightening force for the straight tube section of the rubber cable sleeve body 1, sufficient locking force space should be reserved in the circumferential docking structure between the tile ring half 41 and the tile ring half 42, that is, in the initial unlocked state, there is a fitting gap for locking force when the tile ring half 41 and the tile ring half 42 are circumferentially docked.

[0059] Example 2

[0060] The utility model is a rubber cable sleeve for protecting the main cable of a suspension bridge. In the suspension bridge structure, the rubber cable sleeve is sleeved on the dispersed transition section of the main cable, so the rubber cable sleeve has a large-diameter end corresponding to the dispersed end of the dispersed transition section of the main cable (for example, at the saddle cover of the cable saddle or the front wall of the anchor chamber, and the front wall of the anchor chamber is taken as an example below), and a small-diameter end corresponding to the concentrated end of the dispersed transition section of the main cable (for example, the main cable section with a circular cross section or the position adjacent to the cable clamp, and the position adjacent to the cable clamp is taken as an example below). The outer contour of the entire rubber cable sleeve is a tapered cylindrical structure.

[0061] The rubber cable sleeve of the utility model has a rubber cable sleeve body formed of EPDM rubber and arranged with a bellows structure at intervals along the axial length. The rubber cable sleeve body is a structure with one side opening around the circumference, and its end face profile is in a C-shape tending to be closed under a non-closed loop state, so that an opening formed along the axial length is formed around the circumference to surround the main cable.

[0062] More specifically, in order to enable the rubber cable cover body to be closed in the circumferential direction, two toothed belts of the zipper assembly are connected to the edges of the opening of the rubber cable cover body on both sides by tying wires or hot-melt bonding, and the rubber cable cover body can be closed in the circumferential direction by the zipper assembly to form a cylindrical structure. The two toothed belts of the zipper assembly are fixedly connected to the corresponding edges of the opening of the rubber cable cover body on both sides along the axial corrugated track of the rubber cable cover body, that is, the toothed belts of the zipper assembly form a corrugated arrangement structure on the rubber cable cover body along the length direction.

[0063] In order to seal the zipper assembly at the opening of the rubber cable sleeve body, an adhesive lining tape with a corrugated structure along the length direction and formed of EPDM rubber is fixed on the inner side of the edge of one side of the opening by hot-melt bonding. The adhesive lining tape extends outward from the side where the opening is located. In order to prevent the adhesive lining tape from affecting the opening / closing pulling action of the zipper assembly, the extended part of the adhesive lining tape should form a Y-shaped forked arrangement structure with the toothed belt of the zipper assembly on the side in the thickness direction of the rubber cable sleeve body. The outer surface of the area where the adhesive lining tape extends from the side is used for bonding with the inner wall on the other side of the opening, so an adhesive layer is prefabricated during bonding or in advance, that is, when the opening of the rubber cable sleeve body is closed, the adhesive lining tape should be laid on the inner side of the opening and form a bonding match with the opposite side.

[0064] In order to realize the assembly connection with the front wall of the anchor chamber, the large diameter end of the rubber cable sleeve body is assembled and connected with the relative structure by means of a flange clamping structure.

[0065] More specifically, before the cable sleeve is installed and when the main cable is erected, a pre-embedded cylinder is anchored at the front wall of the anchor chamber, that is, the pre-embedded cylinder is a relative structure corresponding to the large diameter end of the rubber cable sleeve body in the suspension bridge structure. The pre-embedded cylinder is used to cooperate with the end of the large diameter end of the rubber cable sleeve body, which has a pre-embedded side flange that is radially folded outward to form a fixed flange, and a plurality of bolt through holes are arranged at circumferential intervals on the pre-embedded side flange.

[0066] The large diameter end of the rubber cable sleeve body is provided with a cable sleeve side flange 1 which is folded radially outward. Based on the circumferential opening structure of the rubber cable sleeve body, the cable sleeve side flange 1 is a non-closed structure. Around the circumference of the cable sleeve side flange 1, a plurality of bolt through holes are arranged at intervals, which can form a one-to-one correspondence with each bolt through hole on the above-mentioned embedded side flange. The cable sleeve side flange 1 of the rubber cable sleeve body is axially docked on the embedded side flange of the embedded tube. When the rubber cable sleeve body is in a closed state around the circumference, each bolt through hole on the cable sleeve side flange 1 forms a one-to-one correspondence with each bolt through hole on the embedded side flange. Moreover, a clamping ring 1 is mounted on the rubber cable sleeve body on the side of the cable sleeve side flange 1 opposite to the embedded side flange. The clamping ring 1 is used to lock the following connecting bolt 1, so the clamping ring preferably adopts a circumferential docking structure of the upper and lower halves, and there is no need to form a rigid connection at the circumferential docking. In this way, the embedded side flange, the cable sleeve side flange and the clamping ring, which are axially connected in sequence, are fixedly connected by a plurality of connecting bolts arranged at circumferential intervals to form a flange clamping structure, i.e., a flange assembly, in which the cable sleeve side flange is clamped between the embedded side flange and the clamping ring.

[0067] In order to realize the assembly connection with the adjacent cable clamp, the small diameter end of the rubber cable sleeve body is assembled and connected with the cable clamp by means of a flange clamping structure.

[0068] More specifically, the side of the cable clamp facing the divergent section of the main cable serves as a relative structure for matching the rubber cable sleeve body. A transition tube is fixedly connected to the end of the cable clamp in a circumferential hoop structure, and the transition tube is used to match the small-diameter end of the rubber cable sleeve body. The end of the transition tube has a fixed flange folded radially outward, and a plurality of bolt through holes are arranged at circumferential intervals on the fixed flange.

[0069] At the small diameter end of the rubber cable sleeve body, there is a cable sleeve side flange 2 which is folded radially outward. Based on the circumferential opening structure of the rubber cable sleeve body, the circumference of the cable sleeve side flange 2 is a non-closed structure. Around the circumference of the cable sleeve side flange 2, a plurality of bolt through holes are arranged at intervals, which can form a one-to-one correspondence with the bolt through holes on the fixed flange. The cable sleeve side flange 2 of the rubber cable sleeve body is axially docked on the fixed flange of the transition tube. When the rubber cable sleeve body is in a closed circumferential state, the bolt through holes on the cable sleeve side flange 2 form a one-to-one correspondence with the bolt through holes on the fixed flange. Moreover, a clamping ring 2 is mounted on the rubber cable sleeve body on the side of the cable sleeve side flange 2 opposite to the fixed flange. The clamping ring 2 is used to lock the following connecting bolt 2, so the clamping ring 2 preferably adopts a circumferential docking structure of the upper and lower halves, and there is no need to form a rigid connection at the circumferential docking. In this way, the fixed flange, the cable sleeve side flange 2 and the clamping ring 2, which are axially connected in sequence, are fixedly connected by a plurality of connecting bolts 2 arranged at circumferential intervals to form a flange clamping structure, i.e., flange assembly 2, and the cable sleeve side flange 2 is clamped in the middle by the fixed flange and the clamping ring 2.

[0070] Example 3

[0071] The utility model is a rubber cable sleeve for protecting the main cable of a suspension bridge. In the suspension bridge structure, the rubber cable sleeve is sleeved on the dispersed transition section of the main cable, so the rubber cable sleeve has a large-diameter end corresponding to the dispersed end of the dispersed transition section of the main cable (for example, at the cable saddle cover or the front wall of the anchor room, and the cable saddle cover is taken as an example below), and a small-diameter end corresponding to the concentrated end of the dispersed transition section of the main cable (for example, a main cable section with a circular cross section or a position near a cable clamp, and the main cable section with a circular cross section is taken as an example below). The outer contour of the entire rubber cable sleeve is a tapered cylindrical structure.

[0072] The rubber cable sleeve of the utility model has a rubber cable sleeve body formed of EPDM rubber and arranged with a bellows structure at intervals along the axial length. The rubber cable sleeve body is a structure with one side opening around the circumference, and its end face profile is in a C-shape tending to be closed under a non-closed loop state, so that an opening formed along the axial length is formed around the circumference to surround the main cable.

[0073] More specifically, in order to enable the rubber cable cover body to be closed in the circumferential direction, two toothed belts of the zipper assembly are connected to the edges of the opening of the rubber cable cover body on both sides by tying wires or hot-melt bonding, and the rubber cable cover body can be closed in the circumferential direction by the zipper assembly to form a cylindrical structure. The two toothed belts of the zipper assembly are fixedly connected to the corresponding edges of the opening of the rubber cable cover body on both sides along the axial corrugated track of the rubber cable cover body, that is, the toothed belts of the zipper assembly form a corrugated arrangement structure on the rubber cable cover body along the length direction.

[0074] In order to seal the zipper assembly at the opening of the rubber cable sleeve body, an adhesive lining tape with a corrugated structure along the length direction and formed of EPDM rubber is fixed on the inner side of the edge of one side of the opening by hot-melt bonding. The adhesive lining tape extends outward from the side where the opening is located. In order to prevent the adhesive lining tape from affecting the opening / closing pulling action of the zipper assembly, the extended part of the adhesive lining tape should form a Y-shaped forked arrangement structure with the toothed belt of the zipper assembly on the side in the thickness direction of the rubber cable sleeve body. The outer surface of the area where the adhesive lining tape extends from the side is used for bonding with the inner wall on the other side of the opening, so an adhesive layer is prefabricated during bonding or in advance, that is, when the opening of the rubber cable sleeve body is closed, the adhesive lining tape should be laid on the inner side of the opening and form a bonding match with the opposite side.

[0075] In order to realize the assembly connection with the saddle cover, the large diameter end of the rubber cable sleeve body is assembled and connected with the relative structure by means of a flange clamping structure.

[0076] More specifically, before the cable sleeve is installed and when the main cable is erected, a transition cylinder is fixed to the saddle cover by bolt connection, that is, the transition cylinder is a relative structure corresponding to the large diameter end of the rubber cable sleeve body in the suspension bridge structure. The transition cylinder is used to match the large diameter end of the rubber cable sleeve body. The end portion has a radially outwardly folded fixed flange, and the fixed flange has multiple bolt through holes arranged at circumferential intervals.

[0077] The large diameter end of the rubber cable sleeve body is provided with a cable sleeve side flange that is folded radially outward. Based on the circumferential opening structure of the rubber cable sleeve body, the circumference of the cable sleeve side flange is a non-closed structure. Around the circumference of the cable sleeve side flange, a plurality of bolt through holes are arranged at intervals that can form a one-to-one correspondence with the bolt through holes on the fixed flange. The cable sleeve side flange of the rubber cable sleeve body is axially docked on the fixed flange of the transition tube. When the circumference of the rubber cable sleeve body is closed, the bolt through holes on the cable sleeve side flange form a one-to-one correspondence with the bolt through holes on the fixed flange. Moreover, a clamping ring is mounted on the rubber cable sleeve body on the side of the cable sleeve side flange that is opposite to the fixed flange. The clamping ring is used to lock the following connecting bolts. Therefore, the clamping ring preferably adopts a circumferential docking structure of the upper and lower halves, and there is no need to form a rigid connection at the circumferential docking. In this way, the fixed flange, cable sleeve side flange and clamping ring, which are axially connected in sequence, are fixedly connected by multiple connecting bolts arranged at circumferential intervals to form a flange clamping structure, i.e., a flange assembly, and the cable sleeve side flange is clamped in the middle by the fixed flange and the clamping ring.

[0078] In order to realize the assembly connection with the circular cross-section section of the main cable, the small diameter end of the rubber cable sleeve body is clamped and fixed on the main cable by a clamping structure.

[0079] More specifically, the small diameter end of the rubber cable sleeve body has an axially extending straight tube structure that matches the circular cross-section section of the main cable. The straight tube section of the small diameter end of the rubber cable sleeve body is clamped and fixed on the main cable by a clamp assembly.

[0080] The clamp assembly is formed by circumferentially butting the first and second half-pieces of the tread ring. The first half-piece of the tread ring has a convex butt joint ear at both ends of the circumference, and a plurality of bolt holes are provided at intervals on the first half-piece of the tread ring. The second half-piece of the tread ring has a convex butt joint ear at both ends of the circumference, and a plurality of bolt holes are provided at intervals on the second half-piece of the tread ring, and each bolt hole on the second half-piece of the tread ring on the same side corresponds to each bolt hole on the first half-piece of the tread ring. The first half-piece of the tread ring and the second half-piece of the tread ring, which are butt jointed on the outside of the main cable, are connected by a plurality of bolts installed in the first and second half-pieces of the tread ring on the same side. In order to provide sufficient clamping preload force for the straight section of the rubber cable sleeve body, the first half-piece of the tread ring and the second half-piece of the tread ring should reserve sufficient locking force application space in the circumferential butt joint structure, that is, in the initial state of not being locked, the first half-piece of the tread ring and the second half-piece of the tread ring have a matching gap for locking force application when they are butt jointed.
