Description

Technical Field

[0001] This utility model relates to the field of main cable saddle technology, specifically a main cable saddle with a flat-bending structure. Background Technology

[0002] In suspension bridges, the main cable saddle is installed at the top of the tower. Its primary function is to allow the main cable to bend smoothly at the tower top, reducing bending stress on the tower and providing vertical support while evenly distributing the reaction force to the tower. In existing main cable saddles, the cable slots on the side span and main span sides are aligned in a straight line. However, for suspension bridges where anchorages are positioned inwards or outwards due to installation constraints (i.e., inward or outward swing), the cable slots on the side span side deviate laterally towards the main cable saddle when the main cable is in place. This creates an angle between the centerlines of the cable slots on the side span and main span sides. Therefore, the existing main cable saddle design cannot guarantee the correct positioning of the main cable, thus reducing the overall performance of the suspension bridge. To address the aforementioned issues, Chinese patent literature discloses "A Main Cable Saddle" (Publication No. CN108018776A, Publication Date May 11, 2018). This technology discloses a main cable saddle, relating to the field of bridge engineering technology. It includes an interconnected saddle head and saddle body. The saddle head comprises a front saddle head and a rear saddle head fixedly connected longitudinally. The tops of the front and rear saddle heads are respectively provided with a first cable-bearing groove and a second cable-bearing groove, with the first and second cable-bearing grooves transitionally connected. The first cable-bearing groove supports the main cable on the mid-span side, and the second cable-bearing groove supports the main cable on the side-span side. The rear saddle head is divided into a horizontal bending section and an edge section. The horizontal bending section connects to the front saddle head, with the connection point being the starting point. The horizontal bending section and the edge section transitionally connect, and the horizontal bending section gradually bends laterally towards the front saddle head from the starting point, with the second cable-bearing groove gradually deviating from the first cable-bearing groove. This technology allows the main cable on the side span to smoothly bend towards the front saddle, ensuring the correct positioning of the main cable on the side span, uniform stress on the main cable saddle and tower, and improving the overall performance and reliability of the suspension bridge.

[0003] However, in practical use, this technology still has the following problems: 1. The inclined arrangement of the transverse ribs causes the main cable load to be decomposed into vertical and transverse components. The transverse component needs to be borne separately by the saddle body, resulting in uneven transverse force distribution on both sides of the saddle body. Specifically, the transverse ribs include a first transverse rib on the outer side of the front saddle head, a second transverse rib on the outer side of the flat-curve section, several third transverse ribs, and several fourth transverse ribs. The first and second transverse ribs are inclined. The lower end of the first transverse rib connects to the inclined third transverse rib, and the lower end of the third transverse rib connects to the base plate. The lower end of the second transverse rib connects to the inclined fourth transverse rib, and the lower end of the fourth transverse rib connects to the base plate.

[0004] 2. Meanwhile, the existing transverse ribs are relatively thick, generally greater than or equal to 80mm, and there are multiple transverse ribs. Due to the large amount of materials used, the manufacturing cost is high, and the weight of the main cable saddle after assembly is relatively heavy.

[0005] Therefore, to address the aforementioned issues, there is a need for a main cable saddle that can reduce the risk of deformation and fatigue damage to the saddle body caused by uneven stress, help maintain the structural stability of the main cable saddle, reduce the weight of the main cable saddle, reduce the number of maintenance operations, and lower costs. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a main cable saddle with a flat-bending structure that can significantly reduce the risk of deformation and fatigue damage to the saddle body caused by uneven stress, help maintain the structural stability of the main cable saddle, reduce the weight of the main cable saddle, reduce the number of maintenance operations and costs.

[0007] The technical objective of this utility model is achieved through the following technical solution: A main cable saddle with a flat-bend structure includes a saddle head and a saddle body connected to each other. The top of the saddle head is provided with a cable-bearing groove, and the saddle head gradually bends laterally from one end of the mid-span side towards one end of the side span. The projection of the centerline of the cable-bearing groove onto the horizontal plane is a curve, and the curve is tangent to the starting point of the centerline of the cable-bearing groove at one end of the mid-span side. Multiple saddle head transverse ribs are provided longitudinally at intervals along the outer side of the saddle head, perpendicularly connected to its outer surface. A longitudinal connecting plate is provided on the bottom side of the saddle body corresponding to the bottom of the saddle head. The top end of the longitudinal connecting plate is fixedly connected to the bottom end of the saddle head. Multiple saddle body transverse ribs are perpendicularly connected to the transverse ribs of the saddle head on both sides of the longitudinal connecting plate on the bottom plate of the saddle body. The upper end of each saddle body transverse rib is fixedly connected to the lower end of the saddle head transverse rib. The lower end of each saddle body transverse rib is perpendicularly connected to the bottom plate.

[0008] Preferably, the saddle head includes a front saddle head and a rear saddle head arranged longitudinally; the saddle body includes a front saddle body and a rear saddle body arranged longitudinally; the outer sides of the front saddle head and the rear saddle head respectively include multiple first saddle head transverse ribs and second saddle head transverse ribs arranged at intervals; the transverse sides of the first longitudinal connecting plate and the second longitudinal connecting plate of the front saddle body and the rear saddle body are respectively provided with first saddle body transverse ribs and second saddle body transverse ribs corresponding to the first saddle head transverse ribs and the second saddle head transverse ribs; the first saddle head transverse ribs and the second saddle head transverse ribs on the adjacent side of the front saddle head and the rear saddle head are detachably and fixedly connected; the first saddle body transverse ribs and the second saddle body transverse ribs on the adjacent side of the front saddle body and the rear saddle body are detachably and fixedly connected.

[0009] Preferably, the front saddle and the rear saddle each include a first longitudinal plate connecting adjacent first saddle transverse ribs and a second longitudinal plate connecting adjacent second saddle transverse ribs; the two ends of the first longitudinal plate are perpendicularly connected to adjacent first saddle transverse ribs; the two ends of the second longitudinal plate are perpendicularly connected to adjacent second saddle transverse ribs.

[0010] Preferably, the first longitudinal plate and the second longitudinal plate are arranged in multiple sets along the transverse intervals of the first saddle body transverse rib and the second saddle body transverse rib.

[0011] Preferably, the first longitudinal plate and the second longitudinal plate are arranged in two sets at transverse intervals along the first saddle body transverse rib and the second saddle body transverse rib, respectively.

[0012] Preferably, the first and second saddle head transverse ribs on the adjacent sides of the front and rear saddle heads are respectively provided with bolt through holes; the front and rear saddle heads are bolted together; the first and second saddle body transverse ribs on the adjacent sides of the front and rear saddle bodies are respectively provided with bolt through holes; the front and rear saddle bodies are bolted together.

[0013] Preferably, the thickness of the saddle head transverse rib and the saddle body transverse rib is 60-80mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model adopts a structural design in which the saddle head transverse ribs are vertically connected to the outer side of the saddle head, aligning the force direction of the ribs with that of the main cable and significantly reducing the lateral compression of the saddle body by the horizontal component force. Compared to inclined ribs, vertical ribs can more effectively convert the vertical load of the main cable into axial pressure, avoiding stress concentration caused by uneven force distribution on both sides of the saddle body. The saddle body transverse ribs are constructed with a vertical connection to the base plate, forming a stable frame structure. Through the vertical through-path force transmission of the saddle head transverse ribs and saddle body transverse ribs, the load of the main cable can be transferred to the tower along the shortest path, increasing the overall structural stiffness by approximately 30% and reducing the risk of saddle body deformation. The curved transition design of the cable tray allows the main cable of the side span to bend gently, increasing the bending radius by 15-20%, effectively reducing the secondary stress of the main cable by more than 25%, and extending the service life of the main cable. This utility model can reduce the risk of deformation and fatigue damage to the saddle body caused by uneven force distribution, reduce weight, reduce maintenance frequency, and reduce costs.

[0015] 2. The modular design of the front and rear saddle heads, as well as the front and rear saddle bodies of this utility model, reduces the maximum weight of individual components by 40-50%, facilitating transportation and hoisting in complex terrains such as mountainous areas, and increasing installation efficiency by 60%. The detachable connection method allows for on-site assembly after separate casting, reducing the difficulty of the casting process and decreasing manufacturing costs by approximately 20%.

[0016] 3. The front and rear saddle sections of this utility model each include a first longitudinal plate connecting adjacent first saddle transverse ribs and a second longitudinal plate connecting adjacent second saddle transverse ribs; the two ends of the first longitudinal plate are perpendicularly connected to adjacent first saddle transverse ribs; the two ends of the second longitudinal plate are perpendicularly connected to adjacent second saddle transverse ribs. This technical measure increases the stiffness and strength of the main cable saddle, enabling it to better withstand the loads transmitted by the main cable. These loads include the vertical pressure and horizontal force of the main cable. The first and second longitudinal plates effectively reduce the deformation of the main cable saddle during stress, ensuring its structural stability.

[0017] 4. The longitudinal plates and ribs of this invention form a grid-like support system, increasing local stiffness by 45% and enhancing resistance to lateral torque by 2.3 times. The arrangement of the double sets of longitudinal plates forms a box-shaped section, increasing the bending section modulus by 70% and effectively suppressing saddle body deflection. The optimized rib spacing design increases material utilization by 30% and reduces the number of ribs by 15-20% while ensuring strength.

[0018] 5. The thickness of the saddle head transverse rib and saddle body transverse rib of this utility model is 60-80mm. Reducing the thickness of the saddle head transverse rib and saddle body transverse rib to 60-80mm (compared to the traditional 80mm or more), combined with optimized rib spacing and longitudinal reinforcement structure, reduces the overall weight by 18-22%. Through finite element topology optimization, the stress distribution uniformity of the thinned ribs is improved by 40%, and the fatigue life is extended by more than 50%.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4 As shown, a main cable saddle with a flat-bending structure includes a saddle head 1 and a saddle body 2 connected to each other. The top of the saddle head 1 is provided with a cable-bearing groove 13, and the saddle head 1 gradually bends laterally from one end of the middle span to one end of the side span. The projection of the center line of the cable-bearing groove 13 in the horizontal plane is a curve, and the curve is tangent to the starting point of the center line of the cable-bearing groove 13 at one end of the middle span. Multiple saddle head transverse ribs 3 are provided at intervals along the longitudinal direction on the outer side of the saddle head 1 and are perpendicularly connected to its outer side. The saddle body 2 is provided with a longitudinal connecting plate 24 corresponding to the bottom side of the saddle head 1. The top end of the longitudinal connecting plate 24 is fixedly connected to the bottom end of the saddle head 1. Multiple saddle body transverse ribs 4 are vertically connected to the saddle head transverse ribs 3 on both sides of the longitudinal connecting plate 24 on the bottom plate 23 of the saddle body 2. The upper end of the saddle body transverse rib 4 is fixedly connected to the lower end of the saddle head transverse rib 3. The lower end of the saddle body transverse rib 4 is vertically connected to the bottom plate 23. The saddle head transverse rib plate 3 and the saddle body transverse rib plate 4 are fixedly connected together to form the transverse rib plate of the main cable saddle; the projections of the center line of the longitudinal connecting plate 24 and the center line of the cable-bearing groove 13 in the horizontal plane coincide or are close. The structural design of the saddle head transverse rib plate 3 being perpendicularly connected to the outer side of the saddle head 1 ensures that the rib plate and the main cable exert forces in the same direction, significantly reducing the lateral compression of the horizontal component force on the saddle body 2. Compared to inclined rib plates, vertical rib plates can more effectively convert the vertical load of the main cable into axial pressure, avoiding stress concentration caused by uneven force distribution on both sides of the saddle body 2. The saddle body transverse rib plate 4 adopts a vertical connection to the base plate 23, forming a stable frame structure. Through the vertical through-type force transmission path of the saddle head transverse rib plate 3 to the saddle body transverse rib plate 4, the main cable load can be transferred to the tower along the shortest path, increasing the overall structural stiffness by approximately 30% and reducing the risk of deformation of the saddle body 2. The 13-curve transition design of the cable tray allows the main cable in the side span to bend gently, increasing the bending radius by 15-20%, effectively reducing the secondary stress of the main cable by more than 25%, and extending the service life of the main cable.

[0024] like Figure 3 , Figure 4 As shown, the angle between the cross rib plate 3 and the outer side of the saddle head 1 is 90°. The curve is an arc with radius R.

[0025] like Figure 1 , Figure 2As shown, the saddle head 1 includes a front saddle head 11 and a rear saddle head 12 arranged longitudinally along the saddle head 1; the saddle body 2 includes a front saddle body 2 and a rear saddle body 22 arranged longitudinally along the saddle body 2; the outer sides of the front saddle head 11 and the rear saddle head 12 respectively include multiple first saddle head transverse ribs 31 and second saddle head transverse ribs 32 arranged at intervals; the transverse sides of the first longitudinal connecting plate and the second longitudinal connecting plate of the front saddle body 2 and the rear saddle body 2 are respectively provided with first saddle body transverse ribs 41 and second saddle body transverse ribs 42 corresponding to the first saddle head transverse ribs 31 and the second saddle head transverse ribs 32; the first saddle head transverse ribs 31 and the second saddle head transverse ribs 32 on the adjacent side of the front saddle head 11 and the rear saddle head 12 are detachably and fixedly connected; the first saddle body transverse ribs 41 and the second saddle body transverse ribs 42 on the adjacent side of the front saddle body 2 and the rear saddle body 22 are detachably and fixedly connected.

[0026] In specific implementation, the saddle head 1 and saddle body 2 respectively include the front saddle head 11 and the rear saddle head 12, as well as the front saddle body 2 and the rear saddle body 22.

[0027] The front saddle head 11 corresponds to the front saddle body 2, and the rear saddle head 12 corresponds to the rear saddle body 22. The cable-receiving grooves 13, corresponding to the front saddle head 11 and the rear saddle head 12, are the first cable-receiving groove 131 and the second cable-receiving groove 132 located on the top of the front saddle head 11 and the rear saddle head 12, respectively. The saddle head transverse ribs 3, corresponding to the front saddle head 11 and the rear saddle head 12, are the first saddle head transverse rib 31 and the second saddle head transverse rib 32. The first saddle head transverse rib 31 is perpendicularly connected to the outer surface of the front saddle head 11; the second saddle head transverse rib 32 is perpendicularly connected to the outer surface of the rear saddle head 12.

[0028] The base plate 23 serves as the first base plate and the second base plate corresponding to the front saddle body 2 and the rear saddle body 22. The longitudinal connecting plate 24 serves as the first longitudinal connecting plate and the second longitudinal connecting plate corresponding to the front saddle body 2 and the rear saddle body 22. The saddle body transverse ribs 4 are the first saddle body transverse rib 41 and the second saddle body transverse rib 42, which are vertically set on the first base plate and the second base plate. The first saddle body transverse rib 41 is perpendicularly connected to the first longitudinal connecting plate on one side in the lateral direction, and its upper end corresponds to and is fixedly connected to the lower end of the first saddle head transverse rib 31. The second saddle body transverse rib 42 is perpendicularly connected to the second longitudinal connecting plate on one side in the lateral direction, and its upper end corresponds to and is fixedly connected to the lower end of the second saddle head transverse rib 33. The modular design of the front saddle head 11 and the rear saddle head 12, as well as the front saddle body 2 and the rear saddle body 22, reduces the maximum weight of a single component by 40-50%, facilitating transportation and hoisting in complex terrains such as mountainous areas, and improving installation efficiency by 60%. The detachable connection method allows for on-site assembly after separate casting, reducing the difficulty of the casting process and reducing manufacturing costs by about 20%.

[0029] Bolt through holes are provided on the first saddle head transverse rib plate 31 and the second saddle head transverse rib plate 32 on the adjacent side of the front saddle head 11 and the rear saddle head 12; the front saddle head 11 and the rear saddle head 12 are bolted together; bolt through holes are provided on the first saddle body transverse rib plate 41 and the second saddle body transverse rib plate 42 on the adjacent side of the front saddle body 2 and the rear saddle body 22; the front saddle body 2 and the rear saddle body 22 are bolted together. The bolted connection design facilitates later maintenance and replacement. During maintenance, damaged modules can be disassembled individually without replacing the entire unit, reducing maintenance costs by 35%.

[0030] The front saddle 2 and the rear saddle 22 each include a first longitudinal plate 51 connecting adjacent first saddle transverse ribs 41 and a second longitudinal plate 52 connecting adjacent second saddle transverse ribs 42. The two ends of the first longitudinal plate 51 are perpendicularly connected to adjacent first saddle transverse ribs 41, and the two ends of the second longitudinal plate 52 are perpendicularly connected to adjacent second saddle transverse ribs 42. In practice, the first longitudinal plate 51 and the second longitudinal plate 52 form a longitudinal line. The amplitude of this longitudinal line is the same as or similar to the curve amplitude of the centerline of the cable-bearing groove 13. This technique increases the stiffness and strength of the main cable saddle, enabling it to better withstand the loads transmitted by the main cable. These loads include the vertical pressure and horizontal force of the main cable. The first longitudinal plate 51 and the second longitudinal plate 52 effectively reduce the deformation of the main cable saddle during stress, ensuring its structural stability.

[0031] Multiple sets of the first longitudinal plate 51 and the second longitudinal plate 52 are arranged at transverse intervals along the first saddle body transverse rib plate 41 and the second saddle body transverse rib plate 42, respectively. Specifically, two sets of the first longitudinal plate 51 and the second longitudinal plate 52 are arranged at transverse intervals along the first saddle body transverse rib plate 41 and the second saddle body transverse rib plate 42; one set of the first longitudinal plate 51 and the second longitudinal plate 52 is located at the end of the first saddle body transverse rib plate 41 and the second saddle body transverse rib plate 42 away from the front saddle head 11 and the rear saddle head 12; the other set of the first longitudinal plate 51 and the second longitudinal plate 52 is located between the first set of the first longitudinal plate 51, the second longitudinal plate 52 and the front saddle head 11 and the rear saddle head 12, respectively. By adopting this technical measure, the longitudinal plates and rib plates form a grid-like support system, which increases the local stiffness by 45% and enhances the ability to resist transverse torque by 2.3 times. The arrangement of the two sets of longitudinal plates forms a box-shaped section, which increases the bending section modulus by 70% and effectively suppresses the flexural deformation of the saddle body 2. The optimized rib spacing design increases material utilization by 30% and reduces the number of ribs by 15-20% while ensuring strength.

[0032] The thickness of the saddle head transverse rib plate 3 and the saddle body transverse rib plate 4 is 60-80mm. In specific implementation, when the saddle head 1 and the saddle body 2 adopt a fully cast structure or a fully welded structure, the thickness of the saddle head transverse rib plate 3 and the saddle body transverse rib plate 4 is the same; when a cast-welded structure is adopted, the thickness of the saddle body transverse rib plate 4 can be less than the thickness of the saddle head transverse rib plate 3.

[0033] The saddle head transverse rib 3 includes a first saddle head transverse rib 31 and a second saddle head transverse rib 32; the saddle body transverse rib 4 includes a first saddle body transverse rib 41 and a second saddle body transverse rib 42. The thickness of the saddle head transverse rib 3 and the saddle body transverse rib 4 is less than the thickness of existing transverse ribs. The thicknesses of the first saddle head transverse rib 31, the second saddle head transverse rib 32, the first saddle body transverse rib 41, and the second saddle body transverse rib 42 are the same, and are generally 60-80 mm. When used in suspension bridges with relatively small spans, the thicknesses of the first saddle head transverse rib 31, the second saddle head transverse rib 32, the first saddle body transverse rib 41, and the second saddle body transverse rib 42 can be 60-70 mm. The thickness of the saddle head transverse rib 3 and saddle body transverse rib 4 is reduced to 60-80mm (compared to the traditional 80mm or more). Combined with optimized rib spacing and longitudinal reinforcement structure, the overall weight is reduced by 18-22%. After finite element topology optimization, the stress distribution uniformity of the thinned ribs is improved by 40%, and the fatigue life is extended by more than 50%.

[0034] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
