Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a railway bridge construction support device. Background Art

[0002] When the number of reinforced concrete beam spans is small, the cast-in-place method is used to eliminate foundation settlement and inelastic deformation of the support to avoid cracks in the beam concrete, and then the steel pipe column Bailey beam combined support is used for construction.

[0003] In practice, steel pipe column Bailey beam combination support construction is very commonly used. When using this construction support, the steel pipe support is welded by connecting rods, which is troublesome to disassemble. After the construction of the existing Bailey beam, there is a built bridge on the upper side, and the Bailey frame close to the lower side of the bridge is difficult to be transported by crane due to its position. If the Bailey frame is disassembled into Bailey pieces, it is convenient for transportation, but the workload is large, and when the Bailey frame is needed again, it is still necessary to manually reassemble the Bailey pieces, and the whole Bailey frame is troublesome to transport. Generally, it will be disassembled into partial Bailey frames for easy transportation and convenient reassembly and reuse next time, but disassembling into partial Bailey frames is still not convenient.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] See also Figure 1-8 A railway bridge construction support device includes a connecting cylinder 1, an I-beam 2 is fixedly connected to the top of the connecting cylinder 1, and a cylinder disassembly mechanism is arranged on the connecting cylinder 1.

[0032] The cylinder disassembly mechanism includes a fixed ring 33 and a connecting ring 31. The fixed ring 33 is fixedly connected to the outside of the connecting cylinder 1. The connecting ring 31 is fixedly connected to the outside of the connecting cylinder 1 by bolts. The connecting ring 31 is arranged between the fixed rings 33. The port of the connecting ring 31 is fixedly connected to a connecting fixture 32 by bolts.

[0033] Working process: When the bracket needs to be disassembled, the connecting fixture 32 is removed from the cylinder 1 by removing the bolts, which facilitates the quick removal of the connecting fixture 32. Then, the bolts on the connecting fixture 32 are removed to loosen the connecting fixture 32 on the cylinder 1, which facilitates the quick removal of the connecting fixture 32, making the overall disassembly of the cylinder 1 convenient.

[0034] Embodiment 2:

[0035] See also Figure 1-8 This embodiment provides a technical solution for a railway bridge construction support device based on the first embodiment:

[0036] A Bailey frame moving mechanism is provided on the I-beam 2, and the Bailey frame moving mechanism includes a moving plate 41, which is provided in the notch of the I-beam 2, and the upper side of the moving plate 41 is fixedly connected to the jack 42, and the upper side of the jack 42 is fixedly connected to the second support plate 44, and the upper side of the second support plate 44 is fixedly connected to the first support plate 43, and both ends of the moving plate 41 are fixedly connected to fixed blocks 48.

[0037] A threaded rod 45 is disposed on the upper side of the fixing block 48 , a manual swivel 46 is fixedly connected to the outer side of the threaded rod 45 , a third support plate 47 is fixedly connected to the upper end of the threaded rod 45 , and a plurality of movable balls 49 are disposed at the bottom of the fixing block 48 .

[0038] A Bailey frame quick-detachment mechanism is provided on the upper side of the first support plate 43, and the Bailey frame quick-detachment mechanism includes a Bailey plate 51, which is fixedly connected to the upper side of the first support plate 43, and a plurality of support plates 53 are bolted to the side wall of the Bailey plate 51, and a connecting rod 54 is fixedly connected to the side wall of the support plate 53, a second connecting hole 56 is provided in the middle of the support plate 53, and a fixing plate 52 is provided on the support plate 53.

[0039] First connection holes 55 are provided on both sides of the fixing plate 52 , and the fixing plate 52 is connected to the supporting sheet 53 via connection pins 57 .

[0040] Working process: when it is necessary to move the Bailey plate 51 to a specified position, manually rotate the manual swivel 46 to lower the threaded rod 45. The lowering of the threaded rod 45 drives the third support plate 47 to move downward, so that the third support plate 47 releases its support for the inner upper wall of the I-beam 2, making it easier for the jack 42 to move as a whole.

[0041] At the same time, the jack 42 is used manually, so that the jack 42 drives the second support plate 44 to move upward, and the upward movement of the second support plate 44 drives the first support plate 43 to move upward, and the first support plate 43 presses against the Bailey plate 51, so that the Bailey plate 51 is separated from the I-beam 2, and a plurality of movable balls 49 are provided at the bottom of the fixed block 48 to facilitate subsequent staff to push the Bailey plate 51 to the specified position. The overall Bailey plate 51 is transformed from sliding friction to rolling friction, so that the overall Bailey plate 51 is easy to move.

[0042] When the bracket needs to be removed quickly, the connecting pin 57 is manually removed to release the fixing plate 52 and the supporting plate 53, and then the fixing plate 52 is removed to facilitate the Bailey bracket to be released, and then the Bailey bracket moving mechanism is used to quickly disassemble the Bailey bracket.
