Description

Technical Field

[0001] The invention relates to a cable clamp for a suspension bridge, in particular to a pin-connected cable clamp which can effectively prevent deformation and loosening of a locking bolt pair due to tension deformation when serving on a main cable. Background Art

[0002] In the suspension bridge structure, the cable clamp is a conversion locking component that fixes the suspension cable / hanger connected to the bridge deck on the main cable, that is, the main cable of the parabola / catenary structure and the vertically downward suspension cable / hanger form a non-right angle structural matching angle through the cable clamp, and the dynamic load and / or static load of the bridge deck acts on the main cable through the suspension cable / hanger and the cable clamp. It can be seen that the cable clamp is one of the key load-bearing components in the suspension bridge structure.

[0003] In a suspension bridge structure, the vertical downward pulling force of the suspender / suspender rod acts on the main cable of the parabola / catenary structure through the cable clamp. In this way, the vertical downward pulling force borne by the cable clamp will form a component force along the linear direction of the main cable, and the cable clamp has a downward trend along the linear direction of the main cable on the main cable. In order to overcome this downward trend, the cable clamp is usually designed as a split structure, a single arc-shaped upper half of the cable clamp and a lower half of the cable clamp. The upper half of the cable clamp and the lower half of the cable clamp are circumferentially connected and combined by two sets of high-strength locking bolts to form an annular structure that can clamp and hold the main cable, so that the circumferential locking clamping force of the high-strength locking bolt pair is used to make the upper half of the cable clamp and the lower half of the cable clamp generate friction on the main cable that is sufficient to resist the downward force along the linear direction of the main cable.

[0004] In the suspension bridge structure, the cable clamps are divided into two types: straddling type cable clamps and pin-connected type cable clamps according to the different connection structures between the slings / suspenders and the cable clamps. Among them, the straddling type cable clamp is to set a straddling groove with an inwardly concave structure around the outer wall of the cable clamp, and the retractable and deformable sling is straddled on the circumference of the cable clamp. The pin-connected type cable clamp is to set a convex ear plate with a pin hole on the outer circumference of the cable clamp, and the slings / suspenders are pinned to the ear plate of the cable clamp through a pin shaft. The common pin-connected type cable clamp is to form the ear plate at the bottom of the lower half of the cable clamp (usually one piece or two pieces spaced side by side, and the ear plate is located in the center area of ​​the circumference of the lower half of the cable clamp).

[0005] In the suspension bridge structure, the upper and lower parts of the pin-jointed cable clamp form a top-bottom matching structure on the main cable through two sets of locking bolts. The upper part of the cable clamp matches the upper area of ​​the main cable ring, and the lower part of the cable clamp matches the lower area of ​​the main cable ring. The two butt joints of the two sets of locking bolts match the two side areas of the main cable ring. The ear plate protruding downward from the bottom of the lower part of the cable clamp is pinned to the upper end of the suspension cable / suspender rod through a pin shaft, thereby connecting the main cable of the parabola / catenary structure to the bridge deck. However, the above-mentioned pin-jointed cable clamp has the following stress conditions that affect its loosening on the main cable during service:

[0006] - The vertical downward pulling force generated by the sling / suspender rod acts on the ear plate of the lower half of the cable clamp. As the service time increases, the lower half of the cable clamp will produce cumulative fatigue and deform. The deformed lower half of the cable clamp will have a tendency to be detached from the surface of the lower area around the main cable loop. As the detachment tendency increases, the contact pressure of the lower half of the cable clamp on the surface of the lower area around the main cable loop decreases and relaxes;

[0007] -The vertical downward pulling force generated by the sling / suspender rod acts on the lower half of the cable clamp, and then acts on the upper half of the cable clamp through two sets of locking bolts. As the downward pulling force accumulates, the axial tension of the locking bolt pair of the circumferentially connected combined cable clamp upper half and the cable clamp lower half will increase, thereby stretching the locking bolt pair and reducing the stress cross section, which is directly manifested as the relaxation of the circumferentially connected combined structure of the cable clamp upper half and the cable clamp lower half.

[0008] The single or synergistic effect of the above-mentioned stress states will eventually lead to the loosening of the pin-connected cable clamp on the main cable. The friction force originally used to resist the downward force is reduced, which can easily cause the pin-connected cable clamp on the main cable to slide downward and affect the safety of the suspension bridge. This needs to be improved and solved. Summary of the invention

[0009] The technical purpose of the present invention is to provide a pin-connected cable clamp that can effectively prevent deformation and loosening of the locking bolt pair due to tension deformation when serving on the main cable, in view of the particularity of the above-mentioned pin-connected cable clamp and the shortcomings of the prior art.

[0010] The technical purpose of the present invention is achieved through the following technical solutions: an anti-loosening pin-connected cable clamp, which has an upper half of the cable clamp that cooperates with the upper side area of ​​the main cable ring in the suspension bridge structure, and the upper half of the cable clamp is integrally formed with ear plates on both sides for pin-connecting slings / suspenders.

[0011] As one of the preferred solutions, the ear plates on both sides of the upper half of the cable clamp extend downwards respectively, and the end surface of the upper half of the cable clamp is in an inverted U shape. Further, the ear plates on both sides of the upper half of the cable clamp extend downwards at the outer edges of both sides of the cable hole of the cable clamp.

[0012] As one of the preferred solutions, the ear plates on both sides of the upper half of the cable clamp are of bilaterally symmetrical structure.

[0013] As one of the preferred schemes, the ear plates on both sides of the upper half of the cable clamp are formed on the axial local area of ​​the upper half of the cable clamp, and the axial area of ​​the non-formed ear plates of the upper half of the cable clamp is connected to the lower half of the cable clamp through a plurality of sets of locking bolt pairs, and the upper half of the cable clamp and the lower half of the cable clamp are circumferentially connected and combined with the plurality of sets of locking bolt pairs to form a full-circular structural cable hole capable of passing the main cable.

[0014] Furthermore, the ear plates on both sides of the upper half of the cable clamp are formed at the upwardly inclined end of the upper half of the cable clamp when it is matched with the main cable. A lower half filling section is arranged between the ear plates on both sides of the upper half of the cable clamp, and the inner hole profile of the lower half filling section matches the inner hole profile of the lower half of the cable clamp. The lower half filling section is connected to the lower half of the cable clamp in the axial direction and matches the circumferential space of the upper half of the cable clamp in the circumferential direction to wrap the main cable installed in the cable hole.

[0015] Furthermore, the butt joint end between the lower filling section and the lower half of the cable clamp is matched with a stop structure. The ear plates on both sides of the upper half of the cable clamp are respectively fixedly connected to the lower filling section arranged therebetween by multiple locking screws.

[0016] The beneficial technical effects of the present invention are:

[0017] 1. The present invention is based on a pin-joined cable clamp having an upper half of a cable clamp matched with the upper side area of ​​the main cable ring. Ear plates used for pin-joining the sling / suspender rod are formed on both sides of the upper half of the cable clamp in an integrated structure. In the suspension bridge structure, the vertical downward pulling force of the sling / suspender rod is converted into a downward pressure of the upper half of the cable clamp on the corresponding surface of the main cable through the ear plates on both sides of the upper half of the cable clamp, and no downward pulling force is generated on the lower half of the cable clamp and each locking bolt pair, thereby effectively preventing the occurrence of technical problems such as deformation and detachment of the lower half of the cable clamp and / or loosening of the locking bolt pair due to stretching deformation when serving on the main cable. Moreover, converting the downward pulling force into downward pressure can effectively increase the friction between the cable clamp and the main cable, and has a good anti-slip effect, which is reliable and stable.

[0018] 2. The present invention designs the upper half of the cable clamp with ear plates on both sides into an inverted U-shaped structure, which can reliably and stably convert the vertical downward pulling force of the sling / suspender rod into downward pressure on the main cable, and the friction between the cable clamp and the main cable is continuous and stable. This is particularly prominent in the structure where the ear plates on both sides of the upper half of the cable clamp extend downward at the outer edges of the cable hole of the cable clamp. In addition, the present invention designs the ear plates on both sides of the upper half of the cable clamp into a left-right symmetrical structure, and the forces on both sides are balanced and stable;

[0019] 3. The present invention forms the ear plates on both sides in the axial local area of ​​the upper half of the cable clamp, which not only takes into account the technical effect that the upper half of the cable clamp bears the downward pulling force, which is particularly prominent when the ear plates on both sides are formed at the upper half of the cable clamp at the upward inclined end when the cable clamp is matched with the main cable, but also takes into account the technical effect that the cable clamp is reliable and convenient to install / uninstall on the main cable, and also takes into account the technical effect that the cable clamp reliably seals and protects the main cable;

[0020] 4. The present invention provides a lower filling section between the ear plates on both sides of the upper half of the cable clamp, which can be axially connected and fill the axial length of the lower half of the cable clamp. The lower filling section can cooperate with the lower half of the cable clamp and the lower half of the cable clamp to form a reliable sealing and protective effect on the main cable, effectively reducing the erosion of the main cable by corrosive substances (such as water, etc.) in the atmospheric environment; in addition, the lower filling section and the lower half of the cable clamp are butt-jointed at the end with a stop structure, and the axial butt joint is stable and the sealing effect is good.

[0026] The present invention relates to a cable clamp for a suspension bridge, specifically a pin-connected cable clamp that can effectively prevent deformation and loosening of the main cable and / or loosening of the locking bolt pair due to tensile deformation when in service. The main technical content of the present invention is described in detail with multiple embodiments. Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution of the present invention is explained clearly and in detail. Although other embodiments are not separately illustrated, their main structures can still refer to the drawings of Embodiment 1.

[0027] It should be particularly 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 that the present invention contributes to the prior art.

[0028] Example 1

[0029] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention comprises an upper cable clamp 1, a lower cable clamp 2, a lower half filling section 6 and a plurality of locking bolt pairs 4.

[0030] The upper half 1 of the cable clamp is a semicircular structure with an arc-shaped end face, and its inner hole contour structure matches the outer contour of the upper circumferential area of ​​the main cable 7 of the suspension bridge. The upper half 1 of the cable clamp has downwardly extending ear plates 3 on both sides of an axial end, and the ear plates 3 on both sides are formed on both sides of the corresponding ends of the upper half 1 of the cable clamp in an integrated structure. The ear plates 3 on both sides extend downward at the outer edges of the cable hole of the cable clamp (i.e., the full circular hole formed by the circumferential connection of the upper half 1 of the cable clamp and the lower half 2 of the cable clamp, which can be passed through the main cable 7). The bottom of each ear plate 3 has a pin hole that can be passed through the pin shaft 9. The ear plates 3 on both sides are basically in a left-right symmetrical structure along the axial center of the upper half 1 of the cable clamp. The end face of the entire upper half 1 of the cable clamp is in an inverted U shape.

[0031] It can be seen from the structure of the cable clamp upper half 1 that the ear plates 3 on both sides of the cable clamp upper half 1 are formed in the axial local area of ​​the cable clamp upper half 1, and the axial area of ​​the non-formed ear plates 3 of the cable clamp upper half 1 is the same as the structure of the traditional cable clamp upper half. That is, both sides of the axial area (the area between the ear plates 3 and the other axial end) of the non-formed ear plates 3 of the cable clamp upper half 1 have radially outwardly protruding docking platforms, and a plurality of bolt holes are opened on each docking platform.

[0032] The lower half 2 of the cable clamp is a semicircular structure with an arc-shaped end face. Its inner hole contour structure matches the outer contour of the lower area of ​​the main cable 7 of the suspension bridge. The structure of the lower half 2 of the cable clamp is the same as that of the lower half of the traditional cable clamp, except that its axial length is equal to the axial area of ​​the non-formed ear plate 3 of the upper half 1 of the cable clamp, that is, the area where the docking platform is located. The lower half 2 of the cable clamp has radially outwardly convex docking platforms on both sides of the axial direction, and multiple bolt holes are opened on each docking platform; the docking platforms on both sides of the lower half 2 of the cable clamp match the docking platforms of the upper half 1 of the cable clamp in the up and down directions.

[0033] The lower half 2 of the cable clamp of the above structure is circumferentially butt-jointed with two sets of locking bolt pairs 4 at the bottom of the area outside the ear plate 3 of the upper half 1 of the cable clamp (each set of locking bolt pairs corresponds to a docking platform on one side). The upper half 1 of the cable clamp and the lower half 2 of the cable clamp are circumferentially butt-jointed with two sets of locking bolt pairs 4 to form a full-circular structural cable hole capable of passing the main cable 7.

[0034] A lower filling section 6 is arranged between the ear plates 3 on both sides of the cable clamp upper half 1. The lower filling section 6 is a semicircular structure with an arc-shaped end face. Its inner hole contour structure matches the outer contour of the circumferential lower area of ​​the main cable 7 of the suspension bridge, that is, the inner hole curvature basically matches the inner hole curvature of the cable clamp lower half 2; the outer edge contour structure matches the space between the ear plates 3 on both sides of the cable clamp upper half 1. The axial length of the lower filling section 6 corresponds to the axial forming area of ​​the ear plates 3 on the cable clamp upper half 1. In other words, the sum of the axial length of the lower filling section 6 and the axial length of the cable clamp lower half 2 basically matches the axial length of the cable clamp upper half 1. The lower filling section 6 forms an axial structure continuation and filling for the cable clamp lower half 2. The lower filling section 6 of the above structure is connected to the cable clamp lower half 2 in the axial direction and matches the circumferential space of the cable clamp upper half 1 in the circumferential direction to wrap the main cable 7 installed in the cable hole. In order to ensure the stability of the lower half filling section 6 axially docking with the lower half 2 of the cable clamp and to enhance the reliability of the main cable wrapping, the docking end between the lower half filling section 6 and the lower half 2 of the cable clamp is matched with a concave-convex overlap stop structure. In order to ensure the stability of the installation of the lower half filling section 6 on the upper half 1 of the cable clamp, the ear plates 3 on both sides of the upper half 1 of the cable clamp respectively fix the lower half filling section 6 disposed therebetween through multiple locking screws 5, that is, multiple screw holes are opened on the ear plates 3 on each side, and correspondingly, multiple screw holes are opened on the outer edge surface of each side of the lower half filling section 6.

[0035] When the cable clamp of the present invention is used in a suspension bridge structure, the lug plates 3 on both sides of the upper half 1 of the cable clamp are usually placed at the upper inclined end when the main cable 7 is matched, that is, the lug plates 3 on both sides are located at the upper inclined side of the main cable 7, and the lower half 2 of the cable clamp is located at the lower inclined side of the main cable 7. The lug plates 3 on both sides integrally formed with the upper half 1 of the cable clamp are used to pin the sling 8 (or the sling rod) through the pin shaft 9.

[0036] The mating platform mating surface between the cable clamp upper half 1 and the cable clamp lower half 2 can be an integral plane mating, or can be a concave-convex stop surface mating, that is, a concave-convex tooth interlocking structure.

[0037] Example 2

[0038] The invention comprises an upper cable clamp and a lower cable clamp.

[0039] The upper half of the cable clamp is an inverted U-shaped structure with an arc-shaped end face, and its inner hole contour structure matches the outer contour of the upper area of ​​the main cable ring of the suspension bridge. There are ear plates extending downward on both sides of the upper half of the cable clamp, and the ear plates on both sides are formed on the upper half of the cable clamp in an integrated structure. The length of the ear plate on each side corresponds to the axial length of the upper half of the cable clamp; compared with the upper half of the traditional cable clamp, the upper half of the cable clamp has a skirt structure-ear plate extending downward on both sides corresponding to the outer edge of the cable hole. The bottom of each ear plate has a pin hole that can be inserted into the pin shaft, and the ear plates on both sides are basically a left-right symmetrical structure along the axial center of the upper half of the cable clamp. The end face of the entire upper half of the cable clamp is in an inverted U shape.

[0040] The lower half of the cable clamp is a semicircular structure with an arc-shaped end face, and its inner hole contour structure matches the outer contour of the lower side area of ​​the main cable ring of the suspension bridge. The outer contour of the lower half of the cable clamp matches the space between the two side ear plates of the upper half of the cable clamp, that is, the axial length corresponds to the axial length of the upper half of the cable clamp, and the width corresponds to the width between the two side ear plates. The lower half of the cable clamp of the above-mentioned structure is embedded in the inner space of the upper half of the cable clamp of the above-mentioned structure, and the top area of ​​the inner space of the upper half of the cable clamp is circumferentially connected with the inner arc space of the lower half of the cable clamp to form a full-circle cable hole structure that can pass the main cable, thereby matching the circumferential space of the upper half of the cable clamp in the circumferential direction to wrap the main cable passed through the cable hole. In order to ensure the stability of the installation of the lower half of the cable clamp on the upper half of the cable clamp, the ear plates on both sides of the upper half of the cable clamp respectively fix the lower half of the cable clamp arranged therebetween through multiple locking screws, that is, multiple screw holes are opened on the ear plates on each side, and correspondingly, multiple screw holes are opened on the outer edge surface of each side of the lower half of the cable clamp.

[0041] Example 3

[0042] The invention comprises an upper cable clamp, a first lower cable clamp, a second lower cable clamp, a lower filling section and a plurality of locking bolt pairs.

[0043] The upper half of the cable clamp is a semicircular structure with an arc-shaped end face, and its inner hole contour structure matches the outer contour of the upper area of ​​the main cable ring of the suspension bridge. The middle of the upper half of the cable clamp has downwardly extending ear plates on both sides, and the ear plates on both sides are formed on both sides of the middle of the upper half of the cable clamp in an integrated structure. The ear plates on both sides extend downward at the outer edges of the cable hole of the cable clamp (i.e., the full circular hole formed by the circumferential connection of the upper half of the cable clamp and the lower half of the cable clamp, which can be used to pass the main cable). The bottom of each ear plate has a pin hole that can be used to pass the pin shaft. The ear plates on both sides are basically left-right symmetrical structures along the axial center of the upper half of the cable clamp. The end face of the entire upper half of the cable clamp is in an inverted U shape.

[0044] It can be seen from the structure of the upper half of the cable clamp that the ear plates on both sides of the upper half of the cable clamp are formed in the axial middle area of ​​the upper half of the cable clamp, and the axial end areas of the non-formed ear plates of the upper half of the cable clamp are the same as the structure of the upper half of the traditional cable clamp. That is, the two sides of the axial end areas of the non-formed ear plates of the upper half of the cable clamp are respectively provided with radially outwardly protruding docking platforms, and a plurality of bolt holes are opened on each docking platform.

[0045] The structure of the lower half of the cable clamp is the same as that of the lower half of the cable clamp, except that they are located at different positions relative to the upper half of the cable clamp. The lower half of the cable clamp is now described in detail by taking the lower half of the cable clamp as an example, and the specific structure of the lower half of the cable clamp is not repeated. The lower half of the cable clamp is a semicircular structure with an arc-shaped end face, and its inner hole contour structure matches the outer contour of the lower area of ​​the main cable ring of the suspension bridge. The structure of the lower half of the cable clamp is the same as that of the lower half of the traditional cable clamp, except that its axial length is equal to the axial end area (for example, the left end) of the non-formed ear plate of the upper half of the cable clamp. The lower half of the cable clamp has radially outwardly protruding docking platforms on both axial sides, and a plurality of bolt holes are provided on each docking platform; the docking platforms on both sides of the lower half of the cable clamp match the docking platforms at the corresponding ends of the upper half of the cable clamp in the up-down direction.

[0046] The lower half one of the cable clamp of the above structure is circumferentially butt-jointed at the bottom of the axial left end area of ​​the upper half of the cable clamp by two sets of locking bolt pairs (each set of locking bolt pairs corresponds to a docking platform on one side), and the lower half two of the cable clamp is circumferentially butt-jointed at the bottom of the axial right end area of ​​the upper half of the cable clamp by two sets of locking bolt pairs (each set of locking bolt pairs corresponds to a docking platform on one side). The upper half of the cable clamp and the lower half one and the lower half two of the cable clamp are respectively circumferentially butt-jointed by multiple sets of locking bolt pairs to form a full-circular structural cable hole capable of passing the main cable.

[0047] A lower filling section is provided between the ear plates on both sides of the upper half of the cable clamp, that is, between the lower half of the cable clamp and the lower half of the cable clamp. The lower filling section is a semicircular structure with an arc-shaped end face, and its inner hole contour structure matches the outer contour of the lower side area of ​​the main cable circumference of the suspension bridge, that is, the inner hole curvature basically matches the inner hole curvature of the lower half of the cable clamp and the lower half of the cable clamp; the outer edge contour structure matches the space between the ear plates on both sides of the upper half of the cable clamp. The axial length of the aforementioned lower filling section corresponds to the axial forming area of ​​the ear plates on the upper half of the cable clamp. In other words, the sum of the axial length of the lower filling section and the axial length of the lower half of the cable clamp and the lower half of the cable clamp is basically matched with the axial length of the upper half of the cable clamp, and the lower filling section forms an axial structure continuation and filling for the lower half of the cable clamp and the lower half of the cable clamp. The lower filling section of the aforementioned structure is connected to the lower half of the cable clamp and the lower half of the cable clamp in the axial direction, and is matched with the circumferential space of the upper half of the cable clamp to wrap the main cable installed in the cable hole. In order to ensure the stability of the lower half filling section axially docking with the lower half one and the lower half two of the cable clamp, and to enhance the reliability of the main cable wrapping, the two ends of the lower half filling section and the docking ends between the lower half one and the lower half two of the cable clamp are matched with a concave-convex overlap stop structure. In order to ensure the stability of the installation of the lower half filling section on the upper half of the cable clamp, the ear plates on both sides of the upper half of the cable clamp respectively fix the lower half filling section arranged therebetween through multiple locking screws, that is, multiple screw holes are opened on the ear plates on each side, and correspondingly, multiple screw holes are opened on the outer edge surface of each side of the lower half filling section.

[0048] The mating platform mating surface between the upper cable clamp and the first and / or second cable clamp lower halves can be an integral plane mating surface, or a concave-convex stop surface mating surface, that is, a concave-convex tooth interlocking structure.

[0049] The above embodiments are only used to illustrate the present invention, but not to limit it. Although the present invention is described in detail with reference to the above embodiments, a person skilled in the art should understand that the specific technical solutions in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the present invention.
