Description

Technical Field

[0001] The utility model relates to a cable clamp structure of a suspension bridge, belongs to the technical field of suspension bridge devices, and particularly relates to an anti-slip cable clamp for a suspension bridge. Background Art

[0002] The main cable system of a suspension bridge is the main load-bearing and force-transmitting component of the suspension bridge. The cable clamp is a component that tightly clamps the main cable strands and connects the main cable and the suspender. It enhances the overall performance and anti-slip performance of the main cable through tightening force and friction. Cable clamps can be divided into straddling cable clamps and pin-jointed cable clamps according to their structural form. The straddling cable clamp usually adopts a left-right locking structure, while the pin-jointed cable clamp adopts an up-and-down locking structure. All cable clamps are connected and tightened with high-strength screws.

[0003] In the cable clamp structure engineering of the main cable system of a suspension bridge, the problem of cable clamp anti-slip runs through all stages of the structural design, construction and use of the suspension bridge, and has attracted much attention from technical personnel. During the actual construction and use process, if the cable clamp cannot provide sufficient anti-slip force, it will not only change the structural performance of the suspension bridge, but may even cause safety accidents. In the existing cable clamp structure, the main cable of the suspension bridge cable clamp is fastened by friction resistance to resist the sliding of the sling, and this friction resistance is generated by the pre-tension of the high-strength screw that tightens the cable clamp squeezing the main cable. In order to increase the anti-slip ability of the cable clamp, the length of the cable clamp and the number of high-strength screws that tighten the cable clamp are usually increased. However, this will increase the weight and production cost of the cable clamp. Moreover, over time, the pre-tension of the high-strength screw will gradually decrease, resulting in a decrease in the friction resistance between the cable clamp and the main cable. The cable clamp has poor anti-slip ability. When the anti-slip force of the cable clamp is insufficient, the cable clamp will slip on the main cable. After the cable clamp slips, it will change the shape of the main cable and the sling, thereby changing their stress state, thereby affecting the service life and safety of the bridge.

[0004] Patent application number 201921229937.0, filed on July 31, 2019, discloses an anti-slip device for a high-angle, spatially inclined main cable clamp. The device comprises a cable clamp, multiple of which are spaced apart along the length of the main cable; a connector fixedly connected to each end of the cable clamp; a pull rod assembly positioned between two adjacent cable clamps, with the ends of the pull rod assembly connected to the connector; and one end of the cable clamp at the top of the main cable connected to a steel tower via the pull rod assembly. The steel tower is provided with a connector connected to the pull rod assembly, which is welded to the steel tower. While this device provides a certain anti-slip effect, its serial connection through the pull rod assembly increases the weight of the cable clamp. Furthermore, the rigid structure of the pull rod assembly is only suitable for connecting cable clamps over short distances, which undoubtedly requires more cable clamps and pull rod assemblies, further increasing the weight of the cable clamp. Therefore, a cable clamp with improved anti-slip performance and a lighter weight is urgently needed to address the aforementioned shortcomings of the prior art. Summary of the Invention

[0071] Example 1:

[0072] See also Figure 1, an anti-slip cable clamp for a suspension bridge, the anti-slip cable clamp comprising a cable clamp body 1 and a mountain-shaped ear plate portion 2; the mountain-shaped ear plate portion 2 is arranged at the top of the cable clamp body 1 and is arranged parallel to the axis of the cable clamp body 1; the mountain-shaped ear plate portion 2 comprises a lifting ear 3, a first ear plate group 4, and a second ear plate group 5; the lifting ear 3 is arranged in the middle of the top of the cable clamp body 1, and the first ear plate group 4 and the second ear plate group 5 are symmetrically arranged on both sides of the lifting ear 3; the first ear plate group 4 comprises a first left ear plate 41 and a first right ear plate 42 which are symmetrically arranged; the The bottoms of the first left ear plate 41 and the first right ear plate 42 are connected at the top axis of the cable clamp body 1, and the tops of the first left ear plate 41 and the first right ear plate 42 are inclined toward both sides, forming a first V-shaped angle 421; the second ear plate group 5 includes a symmetrically arranged second left ear plate 51 and a second right ear plate 52; the bottoms of the second left ear plate 51 and the second right ear plate 52 are connected at the top axis of the cable clamp body 1, and the tops of the second left ear plate 51 and the second right ear plate 52 are inclined toward both sides, forming a second V-shaped angle 521.

[0073] In the application, see Figure 9 The steel cables drawn from both sides of the main saddle on the main tower are connected to the first left ear plate 41, the first right ear plate 42, and the lifting lug 3 of the first cable clamp. The second left ear plate 51 and the second right ear plate 52 are connected to the first left ear plate 41 and the first right ear plate 42 of the second cable clamp via the steel cables, and the lifting lug 3 of the second cable clamp is connected to the lifting lug 3 of the third cable clamp, thus completing the end-to-end connection. The steel cable drawn from the main saddle can be drawn from the anchor beam of the main saddle or from the main cable. One end of the steel cable is provided with a shackle and connected to the first ear plate group 4 and the second ear plate group 5 via a pin. The through holes 6 on the first ear plate group 4 and the second ear plate group 5 are provided with self-lubricating bushings or spherical bearings to meet the swing of the steel cable. The mountain-shaped ear plate part 2 can be cast together with the cable clamp body 1, or it can be cut and formed from steel plates and then welded to the upper half of the cable clamp.

[0074] Example 2:

[0075] The basic content is the same as Example 1, except that:

[0076] The first inner end 43 of the first left ear plate 41 and the first right ear plate 42 gradually extend and approach toward one side of the lifting ear 3 in a V shape, and are connected to the lifting ear 3 as a whole; the second inner end 53 of the second left ear plate 51 and the second right ear plate 52 gradually extend and approach toward the other side of the lifting ear 3 in a V shape, and are connected to the lifting ear 3 as a whole; the area between one side of the lifting ear 3 and the first inner end 43, and between the other side of the lifting ear 3 and the second inner end 53 are both recessed downward, together forming a mountain-shaped ear plate portion 2.

[0077] In application, in order to avoid the tension of the cable clamp and the main cable being borne by the two ear plates at one end, the ear plates at both ends are connected to the middle lifting ear 3 in a V shape as a whole. In this way, the tension borne by the ear plate at one end is effectively distributed to the entire mountain-shaped ear plate part through the connection between the ear plate and the cable clamp body, and then distributed to other cable clamps through the connecting steel cable. The V-shaped connection design has good structural stability, which not only ensures the structural strength of the cable clamp, but also further improves the anti-slip ability of the entire cable clamp series.

[0078] Example 3:

[0079] The basic content is the same as Example 1, except that:

[0080] The projections of the first V-shaped angle 421 and the second V-shaped angle 521 overlap, and the lifting lug 3 is located at the center line of the overlapping projections. The angles of the first V-shaped angle 421 and the second V-shaped angle 521 are both 35°-37°.

[0081] In application, if the angle is too small, it will cause collision or friction between the connecting steel cables on the two ear plates, and if the angle is too large, it will cause excessive force distribution on the ear plates. Therefore, the angle between the first V-shaped angle 421 and the second V-shaped angle 521 is preferably 36°, and the lifting ear 3 is located at the midline of the angle, that is, the angle between the first V-shaped angle 421 and the second V-shaped angle 521 is 18°, which is conducive to evenly distributing the tension to the lifting ear 3 and ensuring uniform force on both sides; at the same time, after testing, the angle of 36° can ensure uniform force, and at the same time, it can also ensure the structural strength between the ear plate and the lifting ear 3.

[0082] Example 4:

[0083] The basic content is the same as Example 1, except that:

[0084] The cable clamp body 1 comprises symmetrical upper and lower cable halves 11 and 12. The upper cable halves 11 comprise an upper semi-arc plate 111 and an upper connecting platform 112, each extending outward from either side of the upper semi-arc plate 111. The lower cable halves 12 comprise a lower semi-arc plate 121 and a lower connecting platform 122, each extending outward from either side of the lower semi-arc plate 121. A lug plate 123 is provided at the bottom of the lower semi-arc plate 121, parallel to the axis of the lower semi-arc plate 121. The lug plate 123 is shaped like a non-isosceles right triangle, with its long base connected to the lower semi-arc plate 121. A plurality of lug holes 1231 are provided at the apex of the lug plate 123, distributed parallel to the short waist of the lug plate 123. The outer side of the bottom surface of the upper connecting platform 112 is provided with a serrated long protrusion 1121, and the outer side of the top surface of the lower connecting platform 122 is provided with a serrated long recess 1221. A sealing strip 13 is provided in the long recess 1221. After the serrated long protrusion 1121 and the serrated long recess 1221 are coupled and matched with each other through the serrations, the long protrusion 1121 tightly abuts against the sealing strip 13. The top surface of the upper connecting platform 112 is provided with a plurality of upper half perforations 113, which are parallel to the axis of the upper semi-arc plate 111. The top surface of the lower connecting platform 122 is provided with a plurality of lower half perforations 124, which are parallel to the axis of the lower semi-arc plate 121. The plurality of upper half perforations 113 and the plurality of lower half perforations 124 correspond one-to-one.

[0085] In use, the cable clamp body 1 is composed of two parts, the upper and lower parts, and the serrated long strip protrusions 1121 and the serrated long strip recesses 1221 ensure that after the cable clamp is tightened, there will be no front and rear displacement and misalignment, and the sealing strip 13 can reduce the infiltration of rainwater at the joint and reduce the rigid friction between the upper half of the cable body 11 and the lower half of the cable body 12.

[0086] Example 5:

[0087] The basic content is the same as Example 1, except that:

[0088] A bolt fastener 7 is provided between the upper through-hole 113 and the lower through-hole 124. The bolt fastener 7 comprises a screw rod 71, a concave spherical washer 72, a convex spherical washer 73, a nut 74, and a waterproof nut 75. The screw rod 71 is provided with a concave spherical washer 72, a convex spherical washer 73, a nut 74, and a waterproof nut 75 in sequence from the middle to both ends.

[0089] In application, the bolt fastener 7 is a key component to ensure the tight connection between the upper and lower cable bodies. Therefore, multiple washers are provided to prevent the nuts from loosening, and a waterproof nut 75 is added to reduce the risk of rust on the screw rod 71.
