Description

TECHNICAL FIELD

[0001] The present application relates to an improvement of a main cable saddle combination technology, belonging to the field of main cable saddles, and particularly relates to a steel plate combination welded main cable saddle. BACKGROUND

[0002] In a suspension bridge, the main cable saddle mainly functions to support the main cable and change the angle of the main cable smoothly. The structure of the main cable saddle generally includes a saddle head and a base. The saddle head is generally in a U-shaped structure, and the bottom of the U-shaped groove has multiple stepped saddle grooves for arranging the main cable. The groove bottom is in a circular arc structure in the vertical direction. The side walls are usually two side wall panels arranged vertically. The saddle head of the main cable saddle is generally formed by integral casting, and materials such as ZG270-480H and ZG300-500H are commonly used for casting. The base part is usually formed by combination welding of longitudinally arranged rib plates, transversely arranged rib plates, and bottom plates. The longitudinally arranged rib plates, the transversely arranged rib plates, and the bottom plates are usually made of steel plate materials such as Q345R and Q355. The bottom plate and the longitudinally and transversely arranged rib plates are welded together to form a whole through a bevel type weld joint.

[0003] In the prior art, the saddle head of the main cable saddle is formed by casting. Due to the limitations of the casting process itself, casting defects cannot be avoided. As the diameter of the main cable of the suspension bridge increases, the size of the saddle, the thickness of the rib plates, and the thickness of the saddle groove wall all increase accordingly, and the maximum increase can be up to 700 mm. This will further increase the difficulty of casting, prolong the casting cycle, and increase the casting cost.

[0004] A Chinese patent application with the application number CN201821422454.8 and the application date of August 31, 2018 discloses an assembled cable saddle structure, which includes a saddle groove assembly and a saddle body assembly formed by steel plates and connected together. The saddle groove assembly is mainly composed of an arc-shaped saddle groove bottom plate and saddle groove wall plates welded vertically on both sides of the saddle groove bottom plate. The saddle groove assembly has a groove, and multiple segments of arc-shaped saddle groove profile plates with a curvature matching the curvature of the top surface of the saddle groove bottom plate are sequentially assembled in the groove along the length direction of the groove. The top surface of each segment of the saddle groove profile plate is provided with multiple groove paths along the length direction of the groove. The segments of the saddle groove profile plate are smoothly butted along the length direction of the groove, and the groove paths of the top surfaces of the adjacent two segments of the saddle groove profile plate correspond one by one. However, this patent document still does not solve the problems of a longer casting cycle and increased casting cost.

The side of the longitudinal block (211) is connected to the inner side of the saddle groove sidewall steel plate (1), and the other side of the longitudinal block (211) is connected to the side of the two longitudinal blocks (212). The two filling blocks (22) include three longitudinal blocks (221) and four longitudinal blocks (222). The side of the three longitudinal blocks (221) is connected to the other side of the two longitudinal blocks (212), the other side of the three longitudinal blocks (221) is connected to the side of the four longitudinal blocks (222), and the other side of the four longitudinal blocks (222) is connected to the side of the three filling blocks (23). The first longitudinal block (211) is threadedly connected to the saddle groove bottom plate (3) by a bolt (10), the second longitudinal block (212) is connected to the saddle groove bottom plate (3) by a pin (11), the third longitudinal block (221) is threadedly connected to the saddle groove bottom plate (3) by two bolts (12), the fourth longitudinal block (222) is connected to the saddle groove bottom plate (3) by two pins (13), and the third filler block (23) is connected to the saddle groove bottom plate (3) by three bolts (14). The first longitudinal block (211), the second longitudinal block (212), the third longitudinal block (221), the fourth longitudinal block (222), and the third filler block (23) show a decreasing trend in sequence; The top of the saddle groove bottom plate (3) is provided with a threaded hole (101) that communicates with a longitudinal block (211), and a bolt (10) is threadedly engaged with the threaded hole (101). The top of the saddle groove bottom plate (3) is provided with a through hole (111) that communicates with the two longitudinal blocks (212), and a pin (11) is inserted into the through hole (111). The top of the saddle groove bottom plate (3) is provided with two threaded holes (121) that are connected to the three longitudinal blocks (221), and two bolts (12) are threadedly engaged with the two threaded holes (121). The top of the saddle groove bottom plate (3) is provided with a two-through hole (131) that communicates with the four longitudinal blocks (222), and two pins (13) are inserted into the two-through hole (131); The top of the saddle groove bottom plate (3) is provided with a three-threaded hole (141) that communicates with the three filling blocks (23), and the three bolts (14) are threadedly engaged with the three-threaded hole (141); The saddle groove sidewall steel plate (1), saddle groove filling block (2), saddle groove bottom plate (3), and base transverse stiffener (43) are all formed by steel plates. The first filling block (21), the second filling block (22), and the third filling block (23) are connected and fixed to the saddle groove bottom plate (3) by one bolt (10), two bolts (12), and three bolts (14), which can ensure that the saddle groove filling block (2) and the saddle groove bottom plate (3) are closely fitted without gaps. The connection strength between the saddle groove filling block (2) and the saddle groove bottom plate (3) can be improved by one pin (11) and two pins (13), ensuring better matching between the saddle groove and the main cable. The longitudinal stiffener (6) and the side panel (7) are used to reinforce the multiple base transverse stiffeners (43) to improve the stability of the support. The connecting bolt (9) further enhances the fixing effect between the multiple base transverse stiffeners (43).

2. The steel plate composite welded main cable saddle according to claim 1, characterized in that: Each base transverse stiffener (43) has a saddle groove (41) on its top, and the saddle groove bottom plate (3) is inserted into the saddle groove (41); Each of the base transverse stiffeners (43) has a stiffener groove (42) on its front side, and the longitudinal stiffeners (5) are arranged in the stiffener groove (42).

3. The steel plate composite welded main cable saddle according to claim 2, characterized in that: All the saddle groove bottom plates (3) are arranged in an arc shape from left to right along the saddle body bottom plate (8), and the two saddle groove side wall steel plates (1) are vertically arranged on the saddle groove bottom plate (3).

4. The steel plate composite welded main cable saddle according to claim 1, characterized in that: Washers (15) are provided on the first bolt (10), the second bolt (12), and the third bolt (14), and washers (16) are provided on the first pin (11) and the second pin (13).
