Description

Technical Field

[0001] The invention relates to a steel billet transport machine, in particular to a U-turn machine used for rapid steel billet transport. Background Art

[0002] Since the layout of steelmaking, continuous casting and rolling production lines in steel plants is limited or affected by site modifications, the process layout of many production lines is not ideal. In particular, the situation where the continuous casting billet roller table and the rolling line cannot be smoothly connected puts higher requirements on the transportation of billets. Improving hot charging and hot delivery is an important means of energy saving in steel plants.

[0003] When the vertical distance between the billet discharging roller of the continuous casting cooling bed and the inlet of the rolling line heating furnace is less than the size of a billet, and the horizontal distance is greater than the distance between two billets, the current process scheme includes setting up a stand directly on one side of the rolling heating furnace roller, and using a crane with claws to directly hang 4-5 billets from the cooling bed, but the heat loss of the billets is relatively large. The second method is to use a wire rope with a slider to slide the billet onto the roller of the rolling heating furnace. Although the time is short, the area occupied by the equipment is increased, and the surface of the billet is scratched more. The third method is to use a transport chain, but it takes a long time, and there are more equipment and a large amount of maintenance.

[0004] In order to achieve the transfer of steel billets to the transport roller in the shortest time, rapid transportation of steel billets, and hot charging and hot delivery, the applicant has invested a lot of manpower, material resources, and financial resources in research and experiments. In the process of research and experiments, the applicant encountered many technical problems. The main technical problems are as follows.

[0005] How to change the direction of the steel billet so that it can be transferred to the transport roller in the shortest time possible, achieve rapid transportation of the steel billet, and realize the hot loading and hot delivery function?

[0006] How to reduce the weight of the rotating bracket, ensure its own strength and rigidity, and reduce manufacturing costs?

[0007] How to constrain the rotating bracket to flexibly rotate on a fixed axis?

[0008] How to stably support the rotating bracket for fixed-axis rotation?

[0009] How to ensure the rotation accuracy of the rotating bracket?

[0010] How to install the drive components conveniently?

[0011] How can drive-fit components be easily designed, manufactured and installed?

[0012] How to pick up and place steel billets stably? Summary of the invention

[0013] The technical problem to be solved by the present invention is to provide a turning machine for rapid transportation of steel billets, which can turn the steel billets on the cooling bed at any angle of 270 degrees, so that the steel billets can be transferred to the transport roller in the shortest time, thereby realizing rapid transportation of the steel billets and hot loading and hot delivery functions.

[0014] In order to solve the above technical problems, the present invention provides a U-turn machine for rapid transportation of steel billets, comprising a rotating bracket, a slewing device, a dynamic support device, a driving device, and a lifting device;

[0015] The rotating bracket is connected to the dynamic support device;

[0016] The inner end of the rotating bracket is connected to the rotating device;

[0017] The outer end of the rotating bracket is connected to the driving device;

[0018] The lifting device is arranged on the rotating bracket.

[0019] The turning machine for rapid transportation of steel billets of the technical solution can turn the direction of the steel billets on the cooling bed to any angle within 270 degrees, so that the steel billets can be transferred to the transport roller in the shortest time, and the rapid transportation of the steel billets can be achieved. The hot loading and hot delivery functions are realized, the surface scratches of the steel billets are relatively small, the quality of the steel billets is well guaranteed, the steel transportation time is short, the equipment investment is small, the floor space is small, and the temperature drop of the steel billets is small.
