Description

Technical Field

[0001] The invention relates to the technical field of suspension bridge catwalk construction, in particular to a catwalk anti-collision device and an adjacent catwalk structure. Background Art

[0002] To meet the increasing demands for bridge spans and loads, spatial multi-cable suspension bridges have emerged. For example, the Yanji Yangtze River Bridge employs a four-cable layout with different vertical sags at the side and mid-spans. The inner cables are spaced 35.0 meters apart, while the outer cables are spaced 41.0 meters apart. At the tower top, the inner and outer cables are arranged side by side, with a center spacing of 3 meters. The inner cable span is (550 + 1860 + 450) meters = 2860 meters, while the outer cable span is (510 + 1860 + 410) meters = 2780 meters.

[0003] In the existing technology, catwalks are installed under the main cables and are important auxiliary facilities during the construction period of suspension bridges. If the distance between the two main cables is too small (for example, the center distance between the inner and outer main cables of the Yanji Yangtze River Bridge is 3 meters), it is bound to cause collisions between the catwalks of adjacent main cables, which will affect construction safety and may even affect the personal safety of construction workers. Summary of the Invention

[0004] In view of the defects existing in the prior art, the purpose of the present invention is to provide a catwalk anti-collision device and an adjacent catwalk structure, which can solve the problem in the prior art that when the two main cables are too close to each other, there is an impact on construction safety and may even affect the personal safety of construction workers.

[0019] a second slideway provided along the height direction of the bridge, and configured to connect with the second catwalk;

[0020] The second sliding block is slidably buckled on the second slideway and connected to the spacing structure.

[0022] a second connecting plate provided along the height direction of the bridge, and used for connecting with the second catwalk;

[0023] Two second limiting plates are respectively arranged at both ends of the second connecting plate;

[0024] The second slide plate is arranged between the two second limiting plates and is used for mounting the second sliding block.

[0025] In some optional solutions, the second slide is connected to the second catwalk via a second connecting mechanism, and the second connecting mechanism includes:

[0026] a connecting plate, the upper end of which is used to connect to the second catwalk;

[0027] A frame rod is spaced apart from the second slide, the end of the frame rod and the second slide is connected to the lower side of the connecting plate, and the other end of the frame rod is connected to the second slide via a connecting rod.

[0028] In some optional solutions, a plurality of U-shaped buckle units are provided on the upper side of the connecting plate, and the U-shaped buckle units correspond one-to-one to the load-bearing cables of the second catwalk, and the load-bearing cables pass through the U-shaped buckle units.

[0029] In some optional solutions, an oblique support rod is provided between the second slide track and the frame rod.

[0030] In some optional solutions, the spacing structure is an energy dissipation mechanism.

[0031] On the other hand, an adjacent catwalk structure is provided, which includes a plurality of the above-mentioned catwalk anti-collision devices.

[0040] The following is a further detailed description of an embodiment of a catwalk anti-collision device and an adjacent catwalk structure of the present invention with reference to the accompanying drawings.

[0041] like Figure 1 As shown, on the one hand, a catwalk anti-collision device is provided, which includes:

[0042] A first sliding structure 4, which is used to connect with the first catwalk 2;

[0043] A second sliding structure 5, which is used to connect with the second catwalk 3, and the second catwalk 3 is spaced apart from the first catwalk 2;

[0044] The spacing structure 1 is located between the first catwalk 2 and the second catwalk 3. One end is slidably connected to the first catwalk 2 in the longitudinal direction of the bridge through the first sliding structure 4, and the other end is slidably connected to the second catwalk 3 in the height direction of the bridge through the second sliding structure 5.

[0045] When the catwalk anti-collision device is used, the first sliding structure 4 is connected to the first catwalk 2, and the second sliding structure 5 is connected to the second catwalk 3. The spacing structure 1 is located between the first catwalk 2 and the second catwalk 3, and one end of the spacing structure 1 is slidably connected to the first catwalk 2 in the longitudinal direction of the bridge through the first sliding structure 4, and the other end is slidably connected to the second catwalk 3 in the direction of the bridge height through the second sliding structure 5. One end of the spacing structure 1 is slidably connected to the first catwalk 2 in the longitudinal direction of the bridge through the first sliding structure 4, and the other end is slidably connected to the second catwalk 3 in the direction of the bridge height through the second sliding structure 5. On the basis of maintaining the spacing between the first catwalk 2 and the second catwalk 3, it does not affect the relative displacement of the first catwalk 2 and the second catwalk 3 in the direction of the bridge height and the longitudinal direction of the bridge, can prevent the first catwalk 2 and the second catwalk 3 from colliding due to being too close to each other, improve construction safety, and can solve the problem in the prior art that when the two main cables are too close to each other, there is an impact on construction safety and may affect the personal safety of construction workers.

[0046] like Figure 1-Figure 3 As shown, in some optional embodiments, the first sliding structure 4 includes:

[0047] A first slideway 41 is provided along the longitudinal direction of the bridge and is used to connect with the first catwalk 2;

[0048] The first sliding block 42 is slidably buckled on the first slideway 41 and connected to the spacing structure 1 .

[0049] In this embodiment, the structure of the first sliding structure 4 is specifically described. The first sliding structure 4 includes a first slide 41 and a first slider 42. The first slide 41 is connected to the first catwalk 2. The first slide 41 is arranged along the longitudinal bridge direction. The first slider 42 can be slidably buckled on the first slide 41 and connected to the spacing structure 1. The sliding method is simple and easy to manufacture.

[0050] like Figure 1 As shown, in some optional embodiments, the first slide 41 includes:

[0051] A first connecting plate 411 arranged along the longitudinal bridge direction, which is used to connect with the first catwalk 2;

[0052] Two first limiting plates are respectively provided at both ends of the first connecting plate 411;

[0053] The first slide plate 412 is disposed between the two first limiting plates and is used to mount the first sliding block 42 .

[0054] In this embodiment, the specific structure of the first slide 41 is described. The first slide 41 includes a first connecting plate 411, two first limiting plates and a first slide plate 412. The first connecting plate 411 is arranged along the longitudinal bridge direction and is connected to the first catwalk 2. The two first limiting plates are respectively arranged at both ends of the first connecting plate 411. The first slide plate 412 is arranged between the two first limiting plates and is arranged parallel to the first connecting plate 411. The first slider 42 is arranged on the first slide plate 412. The structure is simple and easy to implement. First limiting plates are provided on both sides of the first slide 41 along the slide direction to prevent the first slider 42 from sliding too long and detaching from the first slide 41, thereby further enhancing the stability of the structure.

[0055] In this example, the first slide 41 is an H-shaped steel, and the first slider 42 is buckled on the flange of the H-shaped steel. The first slider 42 slides in the first slide 41 to prevent the first slider 42 from detaching from the first slide 41 when the first catwalk 2 and the second catwalk 3 are displaced in the transverse direction of the bridge, thereby enhancing the stability of the structure. The first connecting plate 411 and the first slider 412 are respectively the flange plates on both sides of the H-shaped steel, and the first slider 42 is a C-shaped steel, which is clamped on the flange plate of the H-shaped steel.

[0056] like Figure 1-Figure 3 As shown, in some optional embodiments, the second sliding structure 5 includes:

[0057] A second slideway 51 is provided along the height direction of the bridge, and is used to connect with the second catwalk 3;

[0058] The second slider 52 is slidably buckled on the second slideway 51 and connected to the spacing structure 1 .

[0059] In this embodiment, the structure of the second sliding structure 5 is specifically described. The second sliding structure 5 includes a second slide 51 and a second slider 52. The second slide 51 is connected to the second catwalk 3. The second slide 51 is arranged along the height direction of the bridge. The second slider 52 can be slidably buckled on the second slide 51 and connected to the spacing structure 1, which simplifies the sliding method and is more convenient to manufacture.

[0060] In this example, the first slide 41 is connected to the first door frame 21 of the first catwalk 2, or is connected to the first catwalk 2 through a first connecting mechanism, and the second slide 51 is connected to the second door frame of the second catwalk 3, or is connected to the second catwalk 3 through a second connecting mechanism 6. The first connecting mechanism and the second connecting mechanism 6 have the same structure, and the connection method can be selected according to specific needs.

[0061] like Figure 1 As shown, in some optional embodiments, the second slide 51 includes:

[0062] A second connecting plate 511 is provided along the height direction of the bridge and is used to connect with the second catwalk 3;

[0063] Two second limiting plates are respectively provided at both ends of the second connecting plate 511;

[0064] The second slide plate 512 is disposed between the two second limiting plates and is used for mounting the second sliding block 52 .

[0065] In this embodiment, the specific structure of the second slide 51 is described. The second slide 51 includes a second connecting plate 511, two second limiting plates and a second slide plate 512. The second connecting plate 511 is arranged along the height direction of the bridge and is connected to the second catwalk 3. The two second limiting plates are respectively arranged at both ends of the second connecting plate 511. The second slide plate 512 is arranged between the two second limiting plates and is arranged parallel to the second connecting plate 511. The second slider 52 is arranged on the second slide plate 512. The structure is simple and easy to implement. Second limiting plates are provided on both sides of the second slide 51 along the slide direction to prevent the second slider 52 from sliding too long and detaching from the second slide 51, thereby further enhancing the stability of the structure.

[0066] In this example, the second slide 51 is an H-shaped steel, and the second slider 52 is buckled on the flange of the H-shaped steel. The second slider 52 slides in the second slide 51 to prevent the second slider 52 from detaching from the second slide 51 when the first catwalk 2 and the second catwalk 3 are displaced in the transverse direction of the bridge, thereby enhancing the stability of the structure. The second connecting plate 511 and the second slider 512 are respectively the flange plates on both sides of the H-shaped steel, and the second slider 52 is a C-shaped steel, which is clamped on the flange plate of the H-shaped steel.

[0067] like Figure 1-Figure 3 As shown, in some optional embodiments, the second slide 51 is connected to the second catwalk 3 through a second connecting mechanism 6, and the second connecting mechanism 6 includes:

[0068] A connecting plate 62, the upper end of which is used to connect to the second catwalk 3;

[0069] A frame rod 61 is spaced apart from the second slide 51 , and the ends of the frame rod 61 and the second slide 51 are connected to the lower side of the connecting plate 62 . The other ends of the frame rod 61 and the second slide 51 are connected via a connecting rod 63 .

[0070] In this embodiment, the second slide 51 is connected to the second catwalk 3 through a second connecting mechanism 6, wherein the second connecting mechanism 6 includes a connecting plate 62, a frame rod 61 and a connecting rod 63, the upper end of the connecting plate 62 is connected to the second catwalk 3, the frame rod 61 and the second slide 51 are spaced apart, the end of the frame rod 61 and the second slide 51 are connected to the lower side of the connecting plate 62, and the connecting rod 63 connects the frame rod 61 and the other end of the second slide 51. This connection structure is more stable, prevents the second slide 51 from separating from the second catwalk 3 when subjected to force, and enhances the stability of the structure.

[0071] In this example, the first slide 41 is connected to the first door frame 21 of the first catwalk 2. When there is a height difference between the first catwalk 2 and the second catwalk 3, the connection method is more reasonable.

[0072] like Figure 1-Figure 3 As shown, in some optional embodiments, a plurality of U-shaped buckle units 621 are provided on the upper side of the connecting plate 62 , and the U-shaped buckle units 621 correspond one-to-one to the load-bearing cables of the second catwalk 3 , and the load-bearing cables pass through the U-shaped buckle units 621 .

[0073] In this embodiment, a plurality of U-shaped buckle units 621 are provided on the upper side of the connecting plate 62. The U-shaped buckle units 621 correspond one-to-one to the load-bearing cables of the second catwalk 3. The load-bearing cables pass through the U-shaped buckle units 621 and are connected to the load-bearing cables of the second catwalk 3 to prevent the connecting plate 62 and the second catwalk 3 from relative displacement in the longitudinal direction of the bridge.

[0074] In this example, the U-shaped buckle unit 621 includes two U-shaped buckles that are spaced apart, and the projections of the two U-shaped buckles overlap in the longitudinal bridge direction, further enhancing the connection effect.

[0075] like Figure 1 and Figure 2 As shown, in some optional embodiments, an oblique support rod 64 is provided between the second slide 51 and the frame rod 61 .

[0076] In this embodiment, an oblique support rod 64 is provided between the second slideway 51 and the frame rod 61 to strengthen the structural strength of the second connecting mechanism 6 and thereby enhance the stability of the overall structure.

[0077] In some optional embodiments, the spacing structure 1 is an energy dissipation mechanism.

[0078] In this embodiment, the spacing structure 1 is set as an energy-absorbing mechanism, which can absorb the vibration generated during the construction of the first catwalk 2 and the second catwalk 3, thereby improving the safety of the construction of the first catwalk 2 and the second catwalk 3.

[0079] In this example, the energy dissipation mechanism can be a friction damper or a viscous damper.

[0080] like Figure 1 As shown, on the other hand, an adjacent catwalk structure is provided, which includes a plurality of the above-mentioned catwalk anti-collision devices.

[0081] When using this adjacent catwalk structure, multiple catwalk anti-collision devices are installed at different positions between two adjacent catwalks. A first sliding structure 4 is connected to the first catwalk 2, and a second sliding structure 5 is connected to the second catwalk 3. A spacing structure 1 is located between the first and second catwalks 2 and 3, and one end of the spacing structure 1 is slidably connected to the first catwalk 2 in the longitudinal direction of the bridge through the first sliding structure 4, and the other end is slidably connected to the second catwalk 3 in the direction of the bridge height through the second sliding structure 5. One end of the spacing structure 1 is slidably connected to the first catwalk 2 in the longitudinal direction of the bridge through the first sliding structure 4, and the other end is slidably connected to the second catwalk 3 in the direction of the bridge height through the second sliding structure 5. While maintaining the spacing between the first and second catwalks 2 and 3, the spacing structure does not affect the relative displacement of the first and second catwalks 2 and 3 in the direction of the bridge height and the longitudinal direction of the bridge. This can prevent the first and second catwalks 2 and 3 from colliding due to being too close to each other, improve construction safety, and solve the problem in the prior art that when two main cables are too close to each other, construction safety is affected and the personal safety of construction workers may be affected.

[0082] In summary, the present application proposes a catwalk anti-collision device and adjacent catwalk structures, which can prevent two adjacent catwalks from colliding and affecting the safety of construction. The adjacent catwalks can be used independently in the longitudinal direction of the bridge and the height direction of the bridge. They will not affect each other due to the installation of the catwalk anti-collision device, but only serve to restrict the relative movement of the two adjacent catwalks in the transverse direction of the bridge. By setting up an energy-absorbing mechanism, the vibration during the construction of the catwalk can be absorbed to improve the safety of the catwalk.
