Description

Technical Field

[0001] This invention relates to cable clamps for suspension bridges, specifically a cable clamp structure using a rib-based force transmission method. Background Technology

[0002] In a suspension bridge structure, the dynamic and static loads on the bridge deck are transferred to the main cable via suspenders (suspenders), and the connection between the suspenders and the main cable is achieved through cable clamps that grip the main cable. Therefore, the forming quality of the cable clamps and the reliability of the gripping connection with the main cable are directly related to the operational stability and safety of the suspension bridge.

[0003] Based on the different molding materials of the cable clamps, they can be divided into cast cable clamps (such as the technology disclosed in Chinese patent document entitled "A Pin-Connected Cable Clamp", publication number CN 202969271 U, publication date June 5, 2013, etc.) and welded cable clamps (such as the technology disclosed in Chinese patent document entitled "A Fully Welded Cable Clamp", publication number CN 107217595 A, publication date September 29, 2017, etc.). Based on the different connection structure between the cable clamp and the sling, they can be divided into straddle-type cable clamps (such as the technology disclosed in Chinese patent document entitled "A Straaddle-Type Cable Clamp", publication number CN 202969272 U, publication date June 5, 2013, etc.) and pin-connected cable clamps (such as the technology of the aforementioned publication number CN 202969271 U, etc.).

[0004] Currently, in suspension bridge structures, regardless of the structural form of the cable clamp, the clamping connection between it and the main cable is usually achieved through shell force transmission. That is, the locking force of the locking bolt pairs installed between the mating pressure-bearing platforms of the adjacent halves of the cable clamp is directly and basically uniformly applied to the main cable by each half, thereby achieving anti-slip bearing clamping of the cable clamp on the main cable.

[0005] The anti-slip bearing capacity of cable clamps on the main cable mainly depends on the friction coefficient between the main cable and the cable clamp, the effective tightening force of the high-strength locking bolt pair, and the lateral pressure of the cable clamp on the main cable. While cable clamps with a shell-type force transmission system can directly and relatively evenly distribute the tightening force of the locking bolt pair onto the main cable through each half, this is not conducive to increasing the lateral pressure of the cable clamp on the main cable. Therefore, during changes in bridge deck live load, as the structural shape and diameter of the main cable change, the anti-slip bearing capacity of the cable clamp on the main cable is easily affected.

[0006] Specifically, during periods of significant changes in the live load on the suspension bridge deck, especially during extreme changes, the axial tension of the main cable due to the Poisson effect will cause changes in the cable's structural shape and a reduction in its diameter to some extent. This will lead to a decrease in the effective fastening force of the high-strength locking bolt pair and a reduction in the lateral pressure of the cable clamp on the main cable, thereby reducing the anti-slip bearing capacity of the cable clamp on the main cable.

[0007] Chinese patent documents disclose a technology entitled "A clamp-type suspension bridge cable clamp" (publication number CN 204282218U, publication date April 22, 2015). In this technology, it is specifically disclosed that the upper half of the cable clamp is circumferentially joined to the lower half by multiple U-shaped bolts straddling the outer perimeter to form a clamp-type circumferential joining assembly.

[0008] Theoretically, this technology, through the U-bolts straddling the circumference of the upper half, can, to some extent, achieve a relatively concentrated stress distribution in the upper half via rib-based force transmission on the main cable. However, the realization of rib-based force transmission in the upper half relies on the downward pull of the U-bolts on the circumference of the upper half, a high-precision match between the U-bolts and the circumference of the upper half, and a high-precision match between the compressive yield of the upper half and the locking of the U-bolts. These technical requirements are difficult to meet in practical applications. Even if they are met, the downward pull at both ends of the U-bolts results in negligible rib-based force transmission on the circumference of the upper half. Moreover, under the action of the U-bolts, only the upper half constituting the cable clamp can achieve rib-based force transmission on the main cable; the lower half still transmits force through the shell on the main cable.

[0009] Therefore, this technology makes it difficult to achieve rib force transmission on the main cable, and even if it is achieved, it is very limited. It is not conducive to improving the lateral pressure of the cable clamp on the main cable. During the change of live load on the bridge deck, the anti-slip bearing capacity of the cable clamp on the main cable is easily affected by the changes in the structural shape and diameter of the main cable. Summary of the Invention

[0010] The technical objective of this invention is to provide a rib-type cable clamp that can effectively improve the lateral pressure of the cable clamp on the main cable and has reliable anti-slip bearing capacity on the main cable, taking into account the special relationship between the cable clamp and the main cable, the special stress of the main cable under the live load of the suspension bridge deck, and the technical deficiencies of existing cable clamp structures.

[0011] The technical solution adopted by the present invention to achieve its technical objective is a rib-transmitting cable clamp, comprising an upper half of the cable clamp and a lower half of the cable clamp;

[0012] The outer periphery of the upper half of the cable clamp has multiple upper ribs arranged along the axial spacing, which are raised in a circular shape. These upper ribs correspond to the radially lateral area of ​​the cable clamp and form an upper pressure bearing part that can be fitted with locking bolt pairs.

[0013] The outer periphery of the lower half of the cable clamp has multiple lower side ribs arranged along the axial spacing, which are raised in a circular shape. These lower side ribs correspond to the area on the lower radial side of the cable clamp and form a lower pressure bearing part that can be fitted with locking bolt pairs.

[0014] The aforementioned technical measures, through the corresponding ribs on the outer periphery of the upper and lower halves of the cable clamp, bear the circumferential locking force of the locking bolt pair. The locking force is applied to the corresponding halves via the upper and lower ribs, and then to the main cable via the halves. On the one hand, this ensures that the upper and lower halves of the cable clamp can be fully stressed and tightly grip the main cable in both the axial and circumferential directions. On the other hand, it can generate stress concentration at the axial nodes of the upper and lower halves of the cable clamp where the corresponding ribs are located, thereby generating a locking stress similar to a wave-shaped concentrated force transmission in the axial direction of the cable clamp, which in turn causes the cable clamp to generate multi-node lateral pressure on the main cable it grips along the axial direction. Thus, within the normal live load range of the suspension bridge deck, the cable clamps of the above-mentioned technical measures are firmly held onto the main cable in a manner essentially consistent with the shell-type force-transmitting cable clamps, and the entire cable clamp has reliable rigidity and high structural strength. When the live load on the suspension bridge deck increases or even undergoes extreme changes, the cable clamps exert lateral pressure through multiple axial nodes on the main cable under the Poisson effect, ensuring a stable force-bearing structure and guaranteeing the anti-slip bearing capacity of the cable clamps on the main cable.

[0015] Compared with the technology in publication number CN 204282218 U, the above-mentioned technical measures are not only reliable and easy to implement, but also generate a locking stress similar to a wave-shaped concentrated force transmission in the axial direction of both the upper and lower halves. This causes the entire circumference of the cable clamp to generate multi-node lateral pressure on the main cable it holds along the axial direction, thereby reliably improving the anti-slip bearing capacity of the cable clamp on the main cable.

[0016] As one of the preferred embodiments, the upper rib corresponds to the top region of the radially side portion of the cable clamp, and has a platform portion that is horizontally folded and extended, serving as a connection to the upper bearing plate;

[0017] The platform portions of at least two adjacent upper ribs on the same radial side of the cable clamp are connected by the same upper bearing plate. The upper bearing plate has bolt holes for mounting locking bolt pairs in the area between the two adjacent upper ribs.

[0018] The lower rib corresponds to the bottom area of ​​the lower radial side of the cable clamp, and has a platform portion that is horizontally folded and extended to serve as a connection to the lower bearing plate;

[0019] Between the platform portions of at least two adjacent lower side ribs on the same radial side of the cable clamp, there is a common lower pressure plate. The lower pressure plate has bolt holes in the area between the two adjacent lower side ribs, which can be used to install locking bolt pairs.

[0020] The aforementioned technical measures, in the pressure-bearing platform structure formed at the circumferential docking of the cable clamps, not only have a simple and easy-to-form structure, but also ensure that the locking force of the locking bolt pair is reliably transmitted to the upper / lower half of the cable clamp via the corresponding ribs. This clearly and reliably forms a transmission path of locking pressure through the ribs, the corresponding half, and the main cable. Stress concentration is clearly and reliably generated at each axial node of the upper / lower half of the cable clamp at the location of the corresponding ribs. This allows the cable clamp to reliably generate multi-node lateral pressure on the main cable it holds along the axial direction, thereby reliably improving the anti-slip bearing capacity of the cable clamp on the main cable by increasing the lateral pressure of the cable clamp on the main cable.

[0021] Furthermore, the upper ribs on the upper half of the cable clamp and the lower ribs on the lower half of the cable clamp are in a one-to-one correspondence.

[0022] Between at least two adjacent lower side ribs on the same radial side of the cable clamp, there is an upwardly extending positioning plate;

[0023] During the circumferential docking and assembly of the upper half and the lower half of the cable clamp, the positioning plate on the lower half of the cable clamp is embedded between the two corresponding adjacent upper ribs on the upper half of the cable clamp.

[0024] Alternatively, as another preferred embodiment of the positioning plate arrangement structure, the upper ribs on the upper half of the cable clamp and the lower ribs on the lower half of the cable clamp are in a one-to-one correspondence.

[0025] The cable clamp has a downwardly extending positioning plate between at least two adjacent upper ribs on the same radial side;

[0026] During the circumferential docking and assembly of the upper half and the lower half of the cable clamp, the positioning plate on the upper half of the cable clamp is embedded between the two corresponding adjacent lower side ribs on the lower half of the cable clamp.

[0027] Alternatively, as a possible alternative to the positioning plate arrangement structure, the upper ribs on the upper half of the cable clamp and the lower ribs on the lower half of the cable clamp have a one-to-one corresponding relationship.

[0028] The cable clamp has a downwardly extending positioning plate between at least two adjacent upper ribs on the same radial side;

[0029] The cable clamp has an upwardly extending positioning plate between at least two adjacent lower side ribs on the same side of the lower radius, and the positioning plate on the lower half of the cable clamp is staggered with the positioning plate on the upper half of the cable clamp.

[0030] During the circumferential docking and assembly of the upper half and the lower half of the cable clamp, the positioning plate on the upper half of the cable clamp is embedded between the two corresponding adjacent lower side ribs on the lower half of the cable clamp, and the positioning plate on the lower half of the cable clamp is embedded between the two corresponding adjacent upper side ribs on the upper half of the cable clamp.

[0031] The above-mentioned technical measures, on the one hand, can reliably achieve axial relative positioning of the upper and lower halves of the cable clamp through the positioning plate during the circumferential docking and assembly process, so as to facilitate easy and efficient circumferential docking and assembly operation; on the other hand, they can help improve the structural strength of the entire cable clamp by using auxiliary ribs and locking bolt pairs.

[0032] Furthermore, the positioning plates are arranged in the axial mid-area of ​​the lower half / upper half of the cable clamp. This technical measure is more conducive to the axial relative positioning operation of the upper and lower halves of the cable clamp during the circumferential docking and assembly process.

[0033] As one of the preferred solutions, the upper half of the cable clamp and the lower half of the cable clamp are joined together by the middle joint surface of the straight edge structure during the circumferential docking process;

[0034] The bolt holes on the upper bearing plate of the upper half of the cable clamp are located outside the middle joint surface of the upper half of the cable clamp.

[0035] The bolt holes on the lower bearing plate of the lower half of the cable clamp are located outside the middle joint surface of the lower half of the cable clamp.

[0036] The above-mentioned technical measures are beneficial to the sealing operation of the cable clamp on the main cable. The requirements for the sealing structure arranged at the joint surface between the upper and lower halves are low. Moreover, the sealing structure arranged at the joint surface between the upper and lower halves can effectively prevent external erosion of the inside of the cable hole, and the sealing effect is good.

[0037] As one of the preferred embodiments, at least two sets of ear plates protruding along the axial length are arranged at the bottom of the lower half of the cable clamp along the radial spacing.

[0038] Each set of ear plates has at least one pin hole for connecting slings / rods.

[0039] The above-mentioned technical measures, through the spacing of the two sets of ear plates at the bottom of the lower half of the cable clamp, prevent the ear plates from being centered on the lower half of the cable clamp. In the suspension bridge structure, the load acting on the lower half of the cable clamp is laterally distributed, which reliably prevents the lower half of the cable clamp from slipping off the main cable under load, and further improves the anti-slip bearing capacity of the cable clamp on the main cable.

[0040] Furthermore, the cable clamp is a welded steel plate assembly structure;

[0041] The lower half of the cable clamp has a set of ear plates at the bottom. The lower side ribs arranged on the outer periphery of the lower half of the cable clamp are divided into multiple segments along the radial direction. The two adjacent segments of the lower side ribs are welded to the left and right sides of the corresponding ear plates.

[0042] The above-mentioned technical measures use steel plates as raw materials to form cable clamps, effectively avoiding the technical defects of casting materials. Compared with cast cable clamps, steel plate formed cable clamps have the advantages of lower forming technical difficulty, higher forming efficiency, lower forming cost, and wider temperature resistance range.

[0043] Furthermore, the lower half of the cable clamp has two sets of ear plates arranged at intervals. These two sets of ear plates divide the lower ribs arranged on the outer periphery of the lower half of the cable clamp into three segments along the radial direction: lower side rib plate one, lower middle rib plate, and lower side rib plate two. The width of the lower middle rib plate is at least twice the width of the lower side rib plate one / the lower side rib plate two. This technical measure creates a double ear plate structure at the bottom of the lower half of the cable clamp, which not only provides high structural strength and stable stress structure between the ear plates and the lower half of the cable clamp, but also effectively and reliably distributes the load acting on the lower half of the cable clamp in the suspension bridge structure. The stress areas on both sides of the lower half of the cable clamp are basically balanced and stable, effectively preventing the lower half of the cable clamp from deforming and slipping off the main cable, thus significantly improving the anti-slip bearing capacity of the cable clamp on the main cable.

[0044] The beneficial technical effects of the present invention are as follows: The above-mentioned technical measures, through the corresponding ribs on the outer periphery of the upper half and lower half of the cable clamp, bear the circumferential locking force of the locking bolt pair, so that the locking force acts on the corresponding half through the upper and lower ribs, and then acts on the main cable from the half. On the one hand, it can ensure that the upper half and lower half of the cable clamp can be fully stressed and hold the main cable in both the axial and circumferential directions. On the other hand, it can generate stress concentration at each node in the axial direction of the upper half and lower half of the cable clamp where the corresponding ribs are located, thereby generating a locking stress similar to a wave-shaped concentrated force transmission in the axial direction of the cable clamp, and thus causing the cable clamp to generate multi-node lateral pressure on the main cable along the axial direction. Thus, within the normal live load range of the suspension bridge deck, the cable clamps of the above-mentioned technical measures are firmly held onto the main cable in a manner essentially consistent with the shell-type force transmission cable clamps, and the entire cable clamp has reliable rigidity and high structural strength. When the live load on the suspension bridge deck increases or even undergoes extreme changes, the cable clamps exert lateral pressure through multiple axial nodes on the main cable under the Poisson effect, ensuring a stable force structure and guaranteeing the anti-slip bearing capacity of the cable clamps on the main cable.

Detailed Implementation

[0050] This invention relates to cable clamps for suspension bridges, specifically a cable clamp structure using a rib-based force transmission method. The technical content of this invention will be described in detail below with several embodiments, wherein Embodiment 1 is illustrated in conjunction with the accompanying drawings—that is… Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution of the present invention will be clearly and thoroughly explained; although other embodiments are not shown in separate drawings, their main structure can still be referred to the drawings of Embodiment 1.

[0051] It should be noted that the accompanying drawings of this invention are schematic, and unnecessary details have been simplified in order to clarify the technical objectives of this invention, so as to avoid obscuring the technical solutions contributed by this invention to the prior art.

[0052] Example 1

[0053] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention includes an upper half 1 of a cable clamp and a lower half 2 of a cable clamp.

[0054] Specifically, the upper half of the cable clamp is a semi-circular arc-shaped plate structure made of rolled or stamped steel plate, with a central joint surface of straight edge structure.

[0055] The inner contour of the upper half of the cable clamp is basically matched with the outer contour of the main cable of the suspension bridge to be clamped.

[0056] On the outer periphery of the upper half 1 of the cable clamp, there are multiple radially protruding upper ribs 11 welded. That is, on the outer periphery of the upper half 1 of the cable clamp, along its axial direction (i.e., the length direction of the upper half 1 of the cable clamp), there are multiple upper ribs 11 arranged at intervals. Each upper rib 11 protrudes outward along the circumferential direction of the upper half 1 of the cable clamp, and each upper rib 11 is cut from a steel plate. Typically, the spacing between adjacent upper ribs 11 is approximately 4 to 10 times (e.g., 5, 7, or 10 times) the thickness of the upper rib 11. Too small a spacing is not conducive to the connection operation of the locking bolt pair described below, nor is it conducive to the formation of stress concentration nodes in the axial direction of rib force transmission. Too large a spacing can easily affect the overall clamping force of the cable clamp on the main cable. The radial protrusion height of the upper rib 11 on the outer periphery of the upper half 1 of the cable clamp is approximately 2 to 5 times (e.g., 3, 4, or 5 times) the thickness of the upper half 1 of the cable clamp. Too small a protrusion is not conducive to the formation of stress concentration nodes in rib force transmission. Too large a protrusion can easily affect the structural stiffness of the rib under stress.

[0057] In the above-mentioned molding structure of the upper half 1 of the cable clamp, the two ends of each upper side rib 11 extend to the middle joint surface of the upper half 1 of the cable clamp, and are basically flush with the corresponding middle joint surface of the upper half 1 of the cable clamp. The two ends of each upper side rib 11 also extend radially outward from the corresponding side of the upper half 1 of the cable clamp in the radial direction (i.e., the transverse direction).

[0058] The upper rib 11 has a platform portion at the top of each end of the radial side of the upper half 1 of the cable clamp, which is formed by a transverse extension and serves to connect the upper pressure plate 12 and the upper pressure plate 13. That is, the upper rib 11 has a platform portion at the top of the transverse sides of the upper half 1 of the cable clamp, and the root of each platform portion is basically located near the inner side of the lower side of the upper half 1 of the cable clamp. This is beneficial for the locking force of the locking bolt pair to be effectively applied to the upper half 1 of the cable clamp through the upper rib 11. The height of each platform portion is basically greater than 0.7 times the radius of the upper half 1 of the cable clamp. This is beneficial for the upper half 1 and the lower half 2 of the cable clamp to hold the main cable tightly under the circumferential assembly of the locking bolt pair. The two platform portions are basically symmetrically arranged along the transverse center of the upper half 1 of the cable clamp. The top edge of the upper rib 11 between the two platform portions is an arc-shaped arch structure, which is formed higher than the two platform portions, and has an aesthetically pleasing appearance.

[0059] Along the length of the upper half 1 of the aforementioned cable clamp, upper pressure plate 12 and upper pressure plate 23 are welded to the platform portions at both ends of each upper rib 11. That is, upper pressure plate 12 is welded to the left platform portion of each upper rib 11, connecting the left platform portions of each upper rib 11 in series; upper pressure plate 23 is welded to the right platform portion of each upper rib 11, connecting the right platform portions of each upper rib 11 in series.

[0060] In the center area of ​​the upper bearing plate 12 corresponding to the two adjacent upper ribs 11, bolt holes for mounting locking bolt pairs 3 are provided. The bolt holes on the upper bearing plate 12 between each pair of adjacent upper ribs 11 are basically on the same straight line and must be located on the outer side of the corresponding side of the upper half 1 of the lower cable clamp, so as not to cause positional interference to the mid-section joint surface of the upper half 1 of the lower cable clamp. In the center area of ​​the upper bearing plate 2 13 corresponding to the two adjacent upper ribs 11, bolt holes for mounting locking bolt pairs 3 are provided. The bolt holes on the upper bearing plate 2 13 between each pair of adjacent upper ribs 11 are basically on the same straight line and must be located on the outer side of the corresponding side of the upper half 1 of the lower cable clamp, so as not to cause positional interference to the mid-section joint surface of the upper half 1 of the lower cable clamp.

[0061] The thickness of the steel plate of the upper half 1 body of the cable clamp, the thickness of the steel plate of the upper rib 11, the thickness of the steel plate of the upper bearing plate 12, and the thickness of the upper bearing plate 13 are basically the same.

[0062] The lower half of the cable clamp 2 is a semi-circular arc-shaped plate structure made of rolled or stamped steel plate, with a straight-edge structure and a central joint surface.

[0063] The inner contour of the lower half 2 of the cable clamp is basically matched with the outer contour of the main cable of the suspension bridge to be clamped, and is basically consistent with the arc width and axial length of the upper half 1 of the cable clamp.

[0064] Two sets of lugs, namely lug 1 24 and lug 2 25, are welded at intervals along the radial width direction on the outer periphery of the lower half 2 of the cable clamp. These two sets of lugs are located on both sides of the center of the transverse width of the lower half 2 of the cable clamp, and the distance from the two sets of lugs to the center of the transverse width of the lower half 2 of the cable clamp is greater than the distance from the two sets of lugs to the corresponding outer side of the lower half 2 of the cable clamp. Typically, the distance to the center of the transverse width is about 1 to 4 times (e.g., 2 times, 3 times or 4 times, preferably 2 to 3 times) of the distance to the corresponding outer side. This helps to prevent the lower half 1 of the cable clamp under stress from slipping off the main cable.

[0065] Ear plate 1 24 and ear plate 25 are formed by protruding downwards along the length of the lower half of the cable clamp 2 at the bottom of the outer periphery of the lower half of the cable clamp 2. Ear plate 1 24 and ear plate 25 are respectively provided with at least one pin hole for pinning the corresponding sling.

[0066] On the outer periphery of the lower half 2 of the cable clamp, multiple radially protruding lower ribs 21 are welded. Each lower rib 21 on the lower half 2 of the cable clamp is required to have a one-to-one corresponding fit with each upper rib 11 on the upper half 1 of the cable clamp. That is, when the upper half 1 of the cable clamp and the lower half 2 of the cable clamp are circumferentially joined together, each lower rib 21 on the lower half 2 of the cable clamp and each upper rib 11 on the upper half 1 of the cable clamp have a one-to-one corresponding fit with each other in the axial direction of the entire cable clamp.

[0067] In other words, multiple lower side ribs 21 are arranged at intervals along the axial direction on the outer periphery of the lower half 2 of the cable clamp. Each lower side rib 21 protrudes outward along the circumferential direction of the lower half 2 of the cable clamp, and each lower side rib 21 is cut from a steel plate. Based on the above-mentioned two sets of ear plates forming on the outer periphery of the lower half 2 of the cable clamp, each lower side rib 21 is divided into three segments by the two sets of ear plates: lower side edge rib 1 211, lower side middle rib 212, and lower side edge rib 213. Lower side edge rib 1 211 and lower side edge rib 213 are located on the outside of the corresponding ear plates, and lower side middle rib 212 is located between the two sets of ear plates. The width of lower side middle rib 212 is at least one time the width of lower side edge rib 1 211 / lower side edge rib 213, preferably two to three times. Each segment of the rib plate that makes up each lower side rib 21 is not only welded to the outer periphery of the lower half 2 of the cable clamp, but also welded to both sides of the corresponding ear plate. The protrusion height of each lower side rib 21 on the outer periphery of the lower half 2 of the cable clamp is less than the protrusion height of the two sets of ear plates on the outer periphery of the lower half 2 of the cable clamp.

[0068] To facilitate molding and improve the overall aesthetics of the cable clamp, the bottom edges of each lower rib 21 are basically flat. Naturally, the radial protrusion height of the lower rib 21 on the outer periphery of the lower half 2 of the cable clamp also corresponds roughly to the radial protrusion height of the upper rib 11 on the outer periphery of the upper half 1 of the cable clamp, which is approximately 2 to 5 times (e.g., 3, 4, or 5 times) the thickness of the lower half 2 of the cable clamp.

[0069] In the above-mentioned forming structure of the lower half 2 of the cable clamp, the two ends of each lower side rib 21 extend to the middle joint surface of the lower half 2 of the cable clamp, and are basically flush with the corresponding middle joint surface of the lower half 2 of the cable clamp. The two ends of each lower side rib 21 also extend radially outward from the radial corresponding side of the lower half 2 of the cable clamp, and the upward extension width is basically consistent with the radial extension width of the upper side rib 11 from the radial corresponding side of the upper half 1 of the cable clamp.

[0070] The lower rib 21 has a platform portion formed by a horizontal fold and extended at the bottom area below both ends of the radial side of the lower half 2 of the cable clamp. This platform is used to connect the lower pressure plate 1 22 and the lower pressure plate 23. Each platform transitions to the bottom edge of the rib with a bevel. For example, the left platform transitions to the bottom edge of the lower side rib 1 211 with a bevel, and the right platform transitions to the bottom edge of the lower side rib 213 with a bevel. In other words, the lower rib 21 has a platform portion located at the bottom of the lower half of the cable clamp 2 on both sides of the transverse direction. The root of each platform portion is basically located near the inner side of the upper side of the lower half of the cable clamp 2. This is conducive to the locking force of the locking bolt pair being effectively applied to the lower half of the cable clamp 2 through the lower rib 21. The height of each platform portion is basically greater than 0.7 times the radius of the lower half of the cable clamp 2. This is conducive to the upper half of the cable clamp 1 and the lower half of the cable clamp 2 being tightly clamped to the main cable under the circumferential assembly and docking of the locking bolt pair. The two platform portions are basically symmetrically arranged along the transverse center of the lower half of the cable clamp 2.

[0071] Along the length of the lower half 2 of the aforementioned cable clamp, a lower bearing plate 1 22 and a lower bearing plate 23 are welded to the platform portions at both ends of each lower rib 21. That is, the lower bearing plate 1 22 is welded to the left platform portion of each lower rib 21, connecting the left platform portions of each lower rib 21 in series; the lower bearing plate 23 is welded to the right platform portion of each lower rib 21, connecting the right platform portions of each lower rib 21 in series.

[0072] In the central area of ​​the lower bearing plate 22 corresponding to the two adjacent lower ribs 21, bolt holes are provided for the installation of locking bolt pairs 3. The bolt holes on the lower bearing plate 22 between each pair of adjacent lower ribs 21 are basically on the same straight line and must be located on the outer side of the corresponding side of the lower half 2 of the upper cable clamp, so as not to cause positional interference to the middle joint surface of the lower half 2 of the upper cable clamp. At the same time, when the upper half 1 of the cable clamp and the lower half 2 of the cable clamp are circumferentially joined, the bolt holes on the upper bearing plate 12 and the bolt holes on the lower bearing plate 22 are in a one-to-one corresponding fit relationship in the upper and lower positions. In the central area of ​​the lower bearing plate 23 corresponding to the two adjacent lower ribs 21, bolt holes are provided for the installation of locking bolt pairs 3. The bolt holes on the lower bearing plate 23 between each pair of adjacent lower ribs 21 are basically on the same straight line and must be located on the outer side of the corresponding side of the lower half 2 of the upper cable clamp, so as not to cause positional interference to the middle joint surface of the lower half 2 of the upper cable clamp. At the same time, when the upper half 1 of the cable clamp and the lower half 2 of the cable clamp are circumferentially joined, the bolt holes on the upper bearing plate 23 and the bolt holes on the lower bearing plate 23 are in a one-to-one corresponding fit relationship in the upper and lower positions.

[0073] The thickness of the steel plate of the lower half of the cable clamp 2 body, the thickness of the steel plate of the lower rib 21, the thickness of the steel plate of the lower bearing plate 22, and the thickness of the lower bearing plate 23 are basically the same. The thickness of the ear plate 24 and the ear plate 25 are relatively thick.

[0074] When the cable clamps of the above structure are applied to the main cable of a suspension bridge, the upper half 1 of the cable clamp is arranged on the upper side of the main cable, and the lower half 2 of the cable clamp is arranged on the lower side of the main cable. The two are circumferentially joined together and locked by locking bolt pairs 3 inserted into the corresponding bolt holes on the upper and lower bearing plates on both sides. The locking bolt pairs 3 are located on the outside of the joint surface of the straight edge of the upper and lower halves of the cable clamp. The seal at the joint surface of the straight edge is not affected by the bolt arrangement structure, the seal is easy to form and also helps to maintain long-term effectiveness.

[0075] To improve the ease of circumferential docking and assembly between the upper half 1 and the lower half 2 of the cable clamp, and to enhance alignment and structural strength, a vertically extending positioning plate 26 is welded to each radial side of the lower half 2. This positioning plate 26 is vertically arranged at the axial midpoint of the lower half 2, positioned between two adjacent lower ribs 21. The upward extension height of each positioning plate 26 extends beyond the top of each lower rib 21. During the circumferential docking and assembly of the upper half 1 and the lower half 2, the positioning plates 26 on both sides of the lower half 2 can be embedded between the corresponding adjacent upper ribs 11 on both sides of the upper half 1. To prevent interference between the positioning plates 26 and the locking bolt pairs 3, bolt holes can be omitted in the area where the positioning plates 26 are located; that is, locking bolt pairs are not arranged there. Based on this consideration, arranging the positioning plates 26 at the axial midpoint of the lower half 2 is most conducive to balancing the forces.

[0076] To facilitate the connection of the maintenance track to the cable clamp, it is best to weld a connecting plate between the two adjacent upper ribs 11 of the upper half 1 of the cable clamp corresponding to the positioning plate 26. The connecting plate is located above the positioning plate 26 and has bolt holes and other necessary connection structures.

[0077] Example 2

[0078] The present invention includes an upper half of a cable clamp and a lower half of a cable clamp.

[0079] Specifically, the upper part of the cable clamp is a semi-circular arc-shaped plate structure made of rolled or stamped steel plate, with a central joint surface with straight edges.

[0080] The inner contour of the upper half of the cable clamp is basically matched with the outer contour of the main cable of the suspension bridge that is to be clamped.

[0081] On the outer periphery of the upper half of the cable clamp, there are multiple radially protruding upper ribs welded. That is, on the outer periphery of the upper half of the cable clamp, along its axial direction (i.e., the length direction of the upper half of the cable clamp), there are multiple upper ribs spaced apart. Each upper rib protrudes outward along the circumference of the upper half of the cable clamp, and each upper rib is cut from a steel plate. Typically, the spacing between adjacent upper ribs is approximately 4 to 10 times (e.g., 5, 7, or 10 times) the thickness of the upper rib. Too small a spacing is not conducive to the connection operation of the locking bolt pair and the formation of stress concentration nodes in the axial direction of rib force transmission. Too large a spacing can easily affect the overall clamping force of the cable clamp on the main cable. The radial protrusion height of the upper rib on the outer half of the cable clamp is approximately 2 to 5 times (e.g., 3, 4, or 5 times) the thickness of the upper half of the cable clamp. Too small a protrusion is not conducive to the formation of stress concentration nodes in rib force transmission. Too large a protrusion can easily affect the structural stiffness of the rib under stress.

[0082] In the above-mentioned upper half of the cable clamp forming structure, the two ends of each upper side rib extend to the middle joint surface of the upper half of the cable clamp, basically keeping flush with the corresponding middle joint surface of the upper half of the cable clamp, and the two ends of each upper side rib also extend radially outward from the corresponding side of the upper half of the cable clamp in the radial direction (i.e., the transverse direction).

[0083] The upper ribs, corresponding to the two ends of the cable clamp's radially lateral portion, have horizontally extended platform sections that connect to the upper pressure plate 1 and upper pressure plate 2. Specifically, the upper ribs have platform sections located at the top of the upper half of the cable clamp's transverse sides. The root of each platform section is approximately located near the inner side of the lower upper half of the cable clamp, facilitating the effective application of the locking force of the locking bolt pair to the upper half of the cable clamp via the upper ribs. The height of each platform section is approximately greater than 0.7 times the radius of the upper half of the cable clamp, ensuring the upper and lower halves of the cable clamp tightly grip the main cable under the circumferential assembly of the locking bolt pair. The platform sections on both sides are arranged approximately symmetrically along the transverse center of the upper half of the cable clamp. The top edge of the upper rib between the two platform sections is an arched structure, higher than the two platform sections, resulting in an aesthetically pleasing appearance.

[0084] Along the length of the upper half of the aforementioned cable clamp, upper pressure plate one and upper pressure plate two are welded to the platform portions at both ends of each upper rib. That is, upper pressure plate one is welded to the left platform portion of each upper rib, connecting the left platform portions of each upper rib in series; upper pressure plate two is welded to the right platform portion of each upper rib, connecting the right platform portions of each upper rib in series.

[0085] In the center area of ​​the upper bearing plate one corresponding to the two adjacent upper ribs, bolt holes are provided for mounting locking bolt pairs. The bolt holes on the upper bearing plate one between each pair of adjacent upper ribs are basically on the same straight line and must be located on the outer side of the corresponding upper half of the lower cable clamp, so as not to cause positional interference to the mid-parting joint surface of the upper half of the lower cable clamp. In the center area of ​​the upper bearing plate two corresponding to the two adjacent upper ribs, bolt holes are provided for mounting locking bolt pairs. The bolt holes on the upper bearing plate two between each pair of adjacent upper ribs are basically on the same straight line and must be located on the outer side of the corresponding upper half of the lower cable clamp, so as not to cause positional interference to the mid-parting joint surface of the upper half of the lower cable clamp.

[0086] The thickness of the steel plate of the upper half of the cable clamp, the thickness of the steel plate of the upper rib, the thickness of the steel plate of the first upper bearing plate, and the thickness of the second upper bearing plate are basically the same.

[0087] The lower half of the cable clamp is a semi-circular arc-shaped plate structure made of rolled or stamped steel plate, with a central joint surface of straight edge structure.

[0088] The inner contour of the lower half of the cable clamp is basically matched with the outer contour of the main cable of the suspension bridge to be clamped, and is basically consistent with the arc width and axial length of the upper half of the cable clamp.

[0089] A set of lugs is welded to the outer periphery of the lower half of the cable clamp, located at the center of the horizontal width of the lower half. The lugs protrude downwards and outwards along the length of the lower half of the cable clamp from the bottom of its outer periphery. At least one pin hole is provided on the lugs for pinning the corresponding sling.

[0090] On the outer periphery of the lower half of the cable clamp, multiple radially convex lower ribs are welded. Each lower rib on the lower half of the cable clamp is required to have a one-to-one correspondence with each upper rib on the upper half of the cable clamp. That is, when the upper half of the cable clamp and the lower half of the cable clamp are circumferentially joined together, each lower rib on the lower half of the cable clamp and each upper rib on the upper half of the cable clamp have a one-to-one correspondence with each other along the axial direction of the entire cable clamp.

[0091] In other words, multiple lower ribs are arranged at intervals along the axial direction of the lower half of the cable clamp's outer periphery. Each lower rib protrudes outward along the circumference of the lower half of the cable clamp, and each lower rib is cut from a steel plate. Based on the aforementioned ear plate arrangement structure of the lower half of the cable clamp, each lower rib is divided into two sections by the ear plate: a lower left rib and a lower right rib. The lower left and lower right ribs are located on the outer sides of the ear plate. The two rib sections that make up each lower rib are welded not only to the lower half of the cable clamp's outer periphery but also to both sides of the ear plate. The protrusion height of each lower rib on the lower half of the outer periphery of the cable clamp is less than the protrusion height of the ear plate on the lower half of the outer periphery of the cable clamp. Of course, the radial protrusion height of the lower rib on the lower half of the outer periphery of the cable clamp is also basically the same as the radial protrusion height of the upper rib on the upper half of the outer periphery of the cable clamp, that is, about 2 to 5 times (e.g., 3 times, 4 times or 5 times) the thickness of the lower half of the cable clamp.

[0092] In the above-mentioned forming structure of the lower half of the cable clamp, the two ends of each lower side rib extend to the middle joint surface of the lower half of the cable clamp, basically keeping flush with the corresponding middle joint surface of the lower half of the cable clamp. The two ends of each lower side rib also extend radially outward from the radial corresponding side of the lower half of the cable clamp, and the upward extension width is basically consistent with the radial extension width of the upper side rib from the radial corresponding side of the upper half of the cable clamp.

[0093] The lower ribs, corresponding to the bottom areas below both ends of the lower radius of the cable clamp, have horizontally extended platform portions that connect the lower pressure plate one and the lower pressure plate two. In other words, the lower ribs have platform portions located at the bottom of the lower half of the cable clamp on both sides of the lateral direction. The root of each platform portion is approximately located near the inner side of the lower half of the cable clamp above, which facilitates the effective application of the locking force of the locking bolt pair to the lower half of the cable clamp through the lower ribs. The height of each platform portion is approximately greater than 0.7 times the radius of the lower half of the cable clamp, which facilitates the circumferential assembly of the locking bolt pair with the upper and lower halves of the cable clamp tightly gripping the main cable. The platform portions on both sides are arranged approximately symmetrically along the lateral center of the lower half of the cable clamp. The top edge of the lower rib between the two platform portions is an arc-shaped arch structure, formed lower than the two platform portions, resulting in an aesthetically pleasing appearance.

[0094] Along the length of the lower half of the aforementioned cable clamp, lower bearing plate one and lower bearing plate two are welded to the platform portions at both ends of each lower rib. Lower bearing plate one is welded to the left platform portion of each lower rib, connecting the left platform portions of each lower rib in series; lower bearing plate two is welded to the right platform portion of each lower rib, connecting the right platform portions of each lower rib in series.

[0095] In the central area of ​​the lower bearing plate corresponding to the two adjacent lower ribs, bolt holes are provided for mounting locking bolt pairs. The bolt holes on the lower bearing plate and between each pair of adjacent lower ribs are basically on the same straight line and must be located on the outer side of the corresponding side of the lower half of the upper cable clamp, so as not to cause positional interference to the middle joint surface of the lower half of the upper cable clamp. At the same time, when the upper half and the lower half of the cable clamp are circumferentially joined together, the bolt holes on the upper bearing plate and the bolt holes on the lower bearing plate are in a one-to-one corresponding fit relationship in the upper and lower positions. In the center area of ​​the lower bearing plate 2 corresponding to the two adjacent lower ribs, bolt holes are provided for mounting locking bolt pairs. The bolt holes on the lower bearing plate 2 between each pair of adjacent lower ribs are basically on the same straight line and must be located on the outer side of the corresponding side of the lower half of the upper cable clamp, so as not to cause positional interference to the middle joint surface of the lower half of the upper cable clamp. At the same time, when the upper half and the lower half of the cable clamp are circumferentially joined together, the bolt holes on the upper bearing plate 2 and the bolt holes on the lower bearing plate 2 are in a one-to-one corresponding fit relationship in the upper and lower positions.

[0096] The thickness of the steel plate in the lower half of the cable clamp, the steel plate in the lower rib, the steel plate in the first lower bearing plate, and the steel plate in the second lower bearing plate are basically the same. The ear plate is relatively thick.

[0097] When the cable clamps with the above structure are applied to the main cable of a suspension bridge, the upper half of the cable clamps are arranged on the upper side of the main cable, and the lower half of the cable clamps are arranged on the lower side of the main cable. The two are circumferentially joined together and locked by locking bolt pairs installed in the corresponding bolt holes on the upper and lower bearing plates on both sides. The locking bolt pairs are located outside the joint surface of the straight edge of the upper and lower halves of the cable clamp. The seal at the joint surface of the straight edge is not affected by the bolt arrangement structure, the seal is easy to form, and it is also conducive to maintaining long-term effectiveness.

[0098] To improve the ease of circumferential docking between the upper and lower halves of the cable clamp, and to enhance alignment and structural strength, a vertically extending positioning plate is welded to each radial side of the lower half of the cable clamp. These positioning plates are vertically positioned at the axial midpoint of the lower half, between two adjacent lower ribs. The upward extension of each positioning plate extends beyond the top of the respective lower rib, allowing the positioning plates on both sides of the lower half to embed between the corresponding adjacent upper ribs on both sides of the upper half during the circumferential docking process. To prevent interference between the positioning plates and the locking bolt pairs, bolt holes can be omitted in the area where the positioning plates are located; that is, locking bolt pairs are not arranged there. Based on this consideration, arranging the positioning plates at the axial midpoint of the lower half of the cable clamp is most beneficial for balancing forces.

[0099] To facilitate the connection of the maintenance track to the cable clamp, it is best to weld a connecting plate between the upper ribs of the two adjacent tracks on the upper half of the cable clamp corresponding to the positioning plate. The connecting plate is located above the positioning plate and has bolt holes and other necessary connection structures.

[0100] Example 3

[0101] The rest of the content of this embodiment is the same as that of embodiment 1 or 2, except that:

[0102] Positioning plates are formed on both radial sides of the upper half of the cable clamp, with each positioning plate extending vertically downward beyond the bottom of the upper rib.

[0103] During the circumferential docking and assembly of the upper and lower halves of the cable clamp, the positioning plate on the upper half of the cable clamp is embedded between the two corresponding adjacent lower side ribs on the lower half of the cable clamp.

[0104] Example 4

[0105] The rest of the content of this embodiment is the same as that of embodiment 1 or 2, except that:

[0106] Two positioning plates are formed on the radial sides of the cable clamp. One positioning plate is formed at the axial middle of the upper half of the cable clamp, extending vertically downward beyond the bottom of the upper rib; the other positioning plate is formed at the axial middle of the lower half of the cable clamp, extending vertically upward beyond the top of the lower rib. The positioning plates on the lower half of the cable clamp and the positioning plates on the upper half of the cable clamp are arranged axially offset. These two positioning plates are arranged at intervals in the middle of the same side of the cable clamp, and there is at least one set of bolt holes between them, so as to avoid the lack of locking force due to the absence of bolt locking when they are arranged close to each other.

[0107] During the circumferential docking and assembly of the upper and lower halves of the cable clamp, the positioning plate on the upper half of the cable clamp is embedded between the two adjacent lower ribs on the lower half of the cable clamp, and the positioning plate on the lower half of the cable clamp is embedded between the two adjacent upper ribs on the upper half of the cable clamp.

[0108] Example 5

[0109] The rest of the content of this embodiment is the same as that of embodiments 1, 2, 3 or 4, except that:

[0110] The upper half of the cable clamp, the upper ribs of the upper half of the cable clamp, and the possible positioning plates are all cast in one piece. The upper pressure platform formed by the upper ribs on the same side of the upper half of the cable clamp is welded with the same upper pressure plate that can connect the upper ribs. The upper pressure plate is a steel plate structure.

[0111] The lower half of the cable clamp body, the lower side ribs of the lower half of the cable clamp, and any possible positioning plates are all cast integral structures; the upper pressure-bearing platform formed by the lower side ribs on the same side of the lower half of the cable clamp is welded with the same lower pressure-bearing plate that can connect the lower side ribs in series, and the lower pressure-bearing plate is a steel plate structure.

[0112] The above embodiments are only used to illustrate the present invention and are not intended to limit it;

[0113] Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still modify the specific technical solutions in the above embodiments, or make equivalent substitutions for some of the technical features, such as multiple butt joints in the length direction of the upper bearing plate on the same side of the upper rib (the butt joints are located at the ends of the same upper rib), etc., and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the present invention.
