Description

Technical Field

[0001] The utility model relates to the technical field of overhead of ballast railway bridges, in particular to a supporting device for overhead of ballast railway bridges. Background Art

[0002] When the local road is widened at the position of the ballast railway bridge, it is necessary to demolish the existing 3-hole railway bridge and jack in a 4-hole 16m long-span culvert. The traditional common railway overhead jacking method is the I100 steel beam, the 3703 rod cross beam and the cross-lifting beam group.

[0003] Since the thickness of the ballast on the bridge deck at the existing bridge span position is 23-27cm, which does not meet the normal penetration of the 3703 rod (height 44cm), in order to ensure the normal operation of the existing line, a special 5m long 20 steel sleeper (height 20cm) cross beam needs to be used for the first railway overhead to penetrate and bolt with the I100 steel beam. After the existing railway bridge slab drops 25cm, the special 20 steel sleeper at the fulcrum pile position is replaced with a 3703 rod. The operation is troublesome and requires the use of 3703 rods and steel sleepers for operation, with a large amount of materials and a cumbersome process. Summary of the Utility Model

Taking the length direction of the support rod as the left-right direction, a plurality of lifting grooves opening downward are formed on the lower end surface of the support rod, and a support pad capable of lifting and lowering in the up-down direction is arranged in the lifting groove.

[0007] The beneficial effect is that when the supporting device for overhead of ballast railway bridges of the utility model is in use, first, the support rod is penetrated under the rail cross beam of the railway, and then the height of the support rod is increased by the lifting and lowering of the support pad, so that the upper end surface of the support rod can support on the lower end surface of the rail cross beam. When the supporting device for overhead of ballast railway bridges of the utility model is in use, only need to penetrate the support rod under the rail and adjust the height of the support pad to make the support rod stably support the rail, and the operation is quick and convenient.

[0008] Further, the support rod is of an I-shaped rod structure, and the support rod includes an upper horizontal section, a vertical section and a lower horizontal section which are integrally formed and connected. The lifting groove is arranged on the lower end surface of the lower horizontal section.

[0009] Beneficial effect: Save materials and reduce costs.

[0010] Further, a plurality of pairs of rib plates are arranged at intervals in the left - right direction between the upper horizontal section and the lower horizontal section, and the two rib plates of each pair are symmetrically disposed on the front and rear sides of the vertical section.

[0011] Further, the rib plates are integrally formed and connected to the corresponding side surfaces of the upper horizontal section, the vertical section, and the lower horizontal section.
