Description

Technical Field

[0001] The present invention relates to the technical field of bridge structures, and in particular to a bridge bearing replacement and delivery device and a bridge bearing replacement and delivery method. Background Art

[0002] Earthquakes are frequent in my country. After an earthquake, the function of bridge bearings may be damaged or even fail. Bearings must be replaced to restore the seismic performance of the bridge. However, the difficulty of replacing bearings varies. As the vertical bearing capacity of the bearings increases, the external dimensions and weight of the bearings also increase. On the one hand, compared with the bearing size and the plane space of the pier top, the size between the pier top and the bottom of the beam is smaller, and bearing replacement often occurs in this narrow space, which is more difficult. On the other hand, the equipment required for lifting and replacing large-tonnage bearings is larger and has stronger performance, and more auxiliary tooling and participating personnel are required, which will also interrupt traffic for a longer time. It can be seen that whether large-tonnage bearings can be replaced quickly and effectively will directly determine the economic and social benefits of later operations.

[0003] The existing equipment for replacing bridge bearings after an earthquake is large in size, inconvenient to use, relatively simple in function, and has low replacement efficiency. The prior art with publication number CN117536140A discloses a bridge bearing replacement device and replacement method, including a clamp enclosed on a bridge pier, a slide rail rotatably arranged on the clamp, a sliding seat slidably arranged on the slide rail, a driving rod hinged on the sliding seat, a mounting seat arranged on the top surface of the bridge pier, and a first driving member for driving the sliding seat to slide; the slide rail is arranged in a direction parallel or perpendicular to the direction of the bridge, the slide rail is fixedly arranged at the bottom of the bridge, the end of the driving rod away from the sliding seat is hinged on the mounting seat, the driving rod is inclined in a direction away from the pier body, and the sliding seat slides along the length direction of the slide rail. The device in the prior art is only suitable for the replacement of small-tonnage bearings with small loads and low pier heights, and is not suitable for the replacement of large-tonnage bearings with large travel in a narrow space. Summary of the invention

[0007] In this arrangement, the support is clamped by the support picking part, and the support telescopic part drives the support driving part and the support picking part to operate simultaneously. This not only enables the replacement of large-stroke and large-tonnage supports in a narrow space, but also makes the movement smoother during support replacement, and the support replacement efficiency and precision are high.

[0108] S39, the driving body drives the rotating pan to rotate, and under the restriction of the second limit column, the left end opening of the two driving support plates increases: the support telescopic part is adjusted again, and the new support is separated from the two driving support plates to realize the installation of the new support.

[0109] This setting can reduce manual labor, improve the efficiency of bearing replacement, and also enable the replacement of large-stroke and large-tonnage bearings in a small space.

[0110] Specifically, in step S5, the lifting and transferring assembly transfers the jack, and the specific steps are:

[0111] S51, placing the lifting and transporting assembly on the lifting assembly, and moving the lifting assembly to the same height as the bridge pier;

[0112] S52, fine-tuning the elastic clamping member so that the elastic clamping member is close to between the bridge and the pier; the fine-tuning method is the same as step S22;

[0113] S53, the telescopic rod is pushed to the left, so that the elastic clamping member can clamp the jack;

[0114] S54, driving the first moving track by the jacking driving member, the first rolling column rollingly moves on the first moving track, and under the restriction of the first limiting column, the lifting seat moves upward, thereby realizing the jack being suspended in the air;

[0115] S55. The jack is disengaged from between the bridge and the pier by extending and retracting the lifting and retracting mechanism, and the jack is located above the lifting assembly. Finally, the jack and the lifting and transferring assembly are transferred to the ground.

[0116] Specifically, when the lifting assembly in the replacement, picking and delivering method moves up and down, the lifting and lowering is mainly achieved through the cooperation of the gear and the rack.

[0117] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
