Description

Technical Field

[0001] This utility model relates to the field of bridge construction, specifically to a beam-storage platform using a foldable triangular support. Background Technology

[0002] Swaying construction of steel box girders is a common method in suspension bridge construction. It is typically used in locations where vertical lifting of the steel box girder is not feasible. However, during swaying construction of the side spans of suspension bridges, when the lifting height is insufficient or the swaying construction of cable-stayed sections cannot move the steel box girder to the storage support, a method of using fixed supports combined with transversely moving supports is usually employed. This method, however, requires a large area of ​​site space and cannot solve the problem of limited site area. Utility Model Content

[0003] This application provides a foldable triangular support platform for swinging and storing steel box girders, which solves the problems of long construction period, large site occupation, and high construction difficulty when site space is limited, which require the construction of a large number of auxiliary supports when swinging and moving steel box girders. It realizes the problem of not being able to transfer steel box girders due to site space limitations and insufficient hoisting height.

[0004] The technical problem solved by this utility model can be achieved using the following technical solutions:

[0005] A beam-storage platform employing a foldable triangular support for swinging and moving, including a transition pier, and further comprising:

[0006] A fixed bracket, which is detachably connected to the side of the transition pier;

[0007] A connecting frame, one end of which is detachably connected to the upper surface of the transition pier, and the lower surface of the other end of which is detachably connected to the top of the fixed bracket;

[0008] The lifting unit is detachably connected to the side of the fixed bracket;

[0009] The storage section is detachably connected to the end face of the other end of the connecting frame, and the lifting section is detachably connected between the storage section and the fixed bracket.

[0010] Slide rail one and slide rail two, wherein slide rail one is detachably connected to the upper surface of the storage section, and slide rail two is detachably connected to the upper surface of the connecting frame, and slide rail one and slide rail two have the same structure;

[0011] The displacement device is slidably connected to the slide rail.

[0012] Furthermore, the storage section includes: a hinge, a movable bracket, and a connecting plate. One end of the movable bracket is detachably connected to the end face of the other end of the connecting bracket via the hinge. The other end of the movable bracket is a suspended end. The connecting plate is fixed to the lower surface of the movable bracket. The connecting plate is also detachably connected to the lifting section. The slide rail is detachably connected to the upper surface of the movable bracket.

[0013] Furthermore, the lifting unit includes a hinge plate and a folding bracket. The hinge plate is fixed to the side of the fixed bracket, one end of the folding bracket is hinged to the hinge plate, and the other end of the folding bracket is detachably connected to the connecting plate.

[0014] Furthermore, the folding bracket is internally threaded with an adjusting rod, which is detachably connected to the connecting plate.

[0015] Furthermore, the fixed bracket has a concrete base at its bottom end, and the fixed bracket is detachably connected to the upper surface of the concrete base. The fixed bracket has a threaded top foot at its top end, and the connecting bracket is detachably connected to the top end of the top foot.

[0016] Furthermore, the distance from the hinge plate to the top of the fixed bracket is greater than the length of the movable bracket.

[0017] The beneficial effects of this utility model are: by adopting a movable support frame, the problem of large space occupation caused by the need to build a large number of support frames is effectively solved, and the support can be deployed when needed without lifting the equipment and moving it again, thus solving the problem that the hoisting height cannot meet the requirements for the swinging of the steel box girder.

[0018] The use of folding supports effectively solves the problem of deploying and supporting the movable supports. This allows the movable supports to rest against the side of the fixed supports when not in use, freeing up space for the lifting equipment to lift the steel box girder and thus reducing the space occupied on the site.

[0019] The use of top feet effectively solves the problem that slide rail one and slide rail two cannot be aligned during the installation of the connecting frame and the movable support. This allows the height of the connecting frame end located on one side of the movable support to be adjusted by the top feet, thereby adjusting the alignment of slide rail one and slide rail two when the movable support is unfolded.

Detailed Implementation Example 1

[0025] Reference Figure 1-3 This is a structural schematic diagram of Embodiment 1 of this utility model. A beam-storage platform using a foldable triangular support for swinging and moving includes a transition pier 1, and further includes:

[0026] Fixed bracket 2, which is detachably connected to the side of transition pier 1;

[0027] The connecting frame 3 is detachably connected at one end to the upper surface of the transition pier 1, and the lower surface of the other end of the connecting frame 3 is detachably connected to the top of the fixed bracket 2.

[0028] The lifting unit is detachably connected to the side of the fixed bracket 2;

[0029] The storage section is detachably connected to the end face of the other end of the connecting frame 3, and the lifting section is detachably connected between the storage section and the fixed bracket 2.

[0030] Slide rail 4 and slide rail 5, slide rail 4 is detachably connected to the upper surface of the storage part, and slide rail 5 is detachably connected to the upper surface of the connecting frame 3, and slide rail 4 and slide rail 5 have the same structure;

[0031] Displacer 6 is slidably connected to slide rail 4.

[0032] In actual use: Assemble the fixed bracket 2 on the side of the transition pier 1, so that the fixed bracket 2 stands on the ground and is connected to the transition pier 1, so that the fixed bracket 2 forms a stable structure and load-bearing strength. Then, install the connecting frame 3 on the top of the fixed bracket 2 and the transition pier 1, and connect the lifting part and the storage part in sequence. The lifting device 15 moves the steel box girder 16 to the side of the fixed bracket 2 by swinging, and then lifts the steel box girder 16 to a height above the top of the fixed bracket 2. Then, unfold the storage part and the lifting part so that the adjacent ends of the slide rail 1 4 and the slide rail 2 5 are connected. Then, place the displacement device 6 on the slide rail 1 4, and then move the steel box girder 16 to the displacement device 6. By traction displacement device 6, the steel box girder 16 is moved from the slide rail 1 4 to the slide rail 2 5 until it is moved above the transition pier 1, completing the displacement and storage.

[0033] During construction, the construction actions between adjacent transition piers 1 should be coordinated to prevent the steel box girder 16 from falling off.

[0034] In this embodiment, at least one pair of slide rail 4 and slide rail 5 are provided respectively. Example 2

[0035] Reference Figure 1-2 The difference in this embodiment is that the storage part includes a hinge 7, a movable bracket 8 and a connecting plate 9. One end of the movable bracket 8 is detachably connected to the end face of the other end of the connecting frame 3 through the hinge 7. The other end of the movable bracket 8 is a suspended end. The connecting plate 9 is fixed to the lower surface of the movable bracket 8. The connecting plate 9 is also detachably connected to the lifting part. The slide rail 4 is detachably connected to the upper surface of the movable bracket 8.

[0036] In actual use: the movable bracket 8 rotates through the hinge 7 so that the upper surface of the movable bracket 8 is on the same horizontal plane as the upper surface of the connecting frame 3, or the upper surface of the movable bracket 8 is higher than the upper surface of the connecting frame 3 at the suspended end, so that the displacement device 6 will not get stuck between the slide rail 1 4 and the slide rail 2 5 when it moves.

[0037] When the lifting device 15 moves the steel box girder, the movable support 8 is placed against the side of the fixed support 2 to make way for the lifting of the steel box girder 16. After being lifted to a certain height, the movable support 8 is unfolded so that the steel box girder 16 is above the movable support 8. Then the displacement device 6 is placed on the slide rail 4, and the steel box girder 16 is placed on the displacement device 6 and disconnected from the lifting device 15 to complete the moving of the steel box girder 16. Example 3

[0038] Reference Figure 1-2 The difference in this embodiment is that the lifting part includes a hinge plate 10 and a folding bracket 11. The hinge plate 10 is fixed to the side of the fixed bracket 2. One end of the folding bracket 11 is hinged to the hinge plate 10, and the other end of the folding bracket 11 is detachably connected to the connecting plate 9.

[0039] In actual use: When the movable bracket 8 is not supported, the folding bracket 11 rests against the side of the fixed bracket 2. When supported, the folding bracket 11 rotates around the hinge plate 10, so that the other end of the folding bracket 11 moves to the vicinity of the connecting plate 9. Then, the folding bracket 11 is pinned to the connecting plate 9 through the pin shaft, so that the folding bracket 11, the fixed bracket 2 and the movable bracket 8 form a triangular support structure. Example 4

[0040] Reference Figure 1 The difference in this embodiment is that the folding bracket 11 is internally threaded with an adjusting rod 12, and the adjusting rod 12 is detachably connected to the connecting plate 9.

[0041] In actual use: The tilting angle of the movable bracket 8 can be adjusted by adjusting rod 12 to prevent incorrect installation from causing slide rail 1 4 and slide rail 2 5 on the movable bracket 8 to fail to align properly.

[0042] In this embodiment, the folding bracket 11 can also be a hydraulic cylinder. Example 5

[0043] Reference Figure 1 The difference in this embodiment is that: the bottom end of the fixed bracket 2 is provided with a concrete base 13, the fixed bracket 2 is detachably connected to the upper surface of the concrete base 13, the top end of the fixed bracket 2 is threadedly connected with a top foot 14, and the connecting frame 3 is detachably connected to the top end of the top foot 14.

[0044] In actual use: the concrete base 13 can make the fixed bracket 2 form a stable support structure under vertical force, preventing the bottom surface supported by the fixed bracket 2 from sinking when under force.

[0045] The height of the end of the connecting frame 3 can be adjusted by the top foot 14, so that the slide rail 1 4 and the slide rail 2 5 can be properly connected, thereby adjusting the gap between the slide rail 1 4 and the slide rail 2 5. Example 6

[0046] Reference Figure 2 The difference in this embodiment is that the distance from the hinge plate 10 to the top of the fixed bracket 2 is greater than the length of the movable bracket 8.

[0047] In actual use: the movable support 8 is attached to one side of the fixed support 2, so that the space after unfolding can be used to hoist the steel box girder 16. When the movable support 8 is not unfolded, it is attached to the hinge plate 10 to create a protrusion, thereby preventing collisions during hoisting. Example 7

[0048] Reference Figure 1-3 A method for swinging and storing beams using a foldable triangular bracket includes at least the aforementioned platform for swinging and storing beams using a foldable triangular bracket, and further includes the following steps:

[0049] The first step is to move the steel box girder 16 to be moved to the side of the fixed support 2 by using the lifting device 15 and the swaying system.

[0050] The second step is to use lifting equipment to lift the steel box girder 16 to a position higher than the top of the fixed support 2;

[0051] The third step is to unfold the movable support 8 so that the steel box girder 16 is located on the upper surface of the movable support 8, and at the same time unfold the folding support 11. The folding support 11 is connected to the connecting plate 9 so that the movable support 8 remains in the unfolded state.

[0052] The fourth step is to place the displacement device 6 on the slide rail 4 located on the upper surface of the movable support 8, and then control the lifting device 15 to lower the steel box girder 16 onto the displacement device 6, and disconnect the lifting device 15 from the steel box girder 16.

[0053] The fifth step involves using the traction displacement device 6 to move the steel box girder 16 from slide rail 4 to slide rail 5, thus completing the storage process.

[0054] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and all such changes are within the protection scope of this technology.
