Abstract
Description
Technical Field
[0001] This utility model belongs to the field of continuous casting technology, and in particular relates to an anti-detachment structure for a spring plate type dummy ingot in a large round billet continuous casting machine. Background Technology
[0002] Continuous casting is a major process in modern metallurgical industry, especially in the steel industry. The continuous casting machine is the equipment production line that realizes this process. The dummy bar is an important part of the continuous casting equipment production line. For large round billet continuous casting machines, spring steel plates can be used as the bar body of the dummy bar. It has a long bar body and a weight of tens of tons. During production, the spring steel plate is subjected to great stress, which can easily lead to deformation and breakage of the spring steel plate, which in turn causes the chain links of the dummy bar body to detach, resulting in production accidents and losses.
[0003] Therefore, designing an anti-detachment structure to prevent the shaft from detaching due to the breakage of the spring plate is a problem that needs to be solved by those skilled in the art. Summary of the Invention
[0004] The purpose of this utility model is to provide an anti-detachment structure for a spring plate type dummy bar in a large round billet continuous casting machine. By setting an anti-detachment mechanism between each link of the dummy bar, and by designing a large-diameter movable opening to cooperate with the shaft, a certain buffering capacity is achieved, which adds an extra layer of protection to the dummy bar body during production. This effectively avoids production accidents caused by the direct detachment of the dummy bar body due to the breakage of the spring plate. It can avoid significant production accident losses at a low cost, and at the same time, it does not affect the original function of the dummy bar.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is an anti-detachment structure for a spring plate type dummy bar in a large round billet continuous casting machine, including a dummy bar body and several anti-detachment mechanisms. The dummy bar body includes several chain links connected in sequence, and a spring plate is provided on several chain links. A torsion member is provided between two adjacent chain links.
[0007] The chain link includes a set of side beams, a support plate is provided between two side beams, the spring plate is fixed on the support plate of several chain links, a fixed opening is provided at the bottom edge of one end of the side beam, and a movable opening is provided at the bottom edge of the other end of the side beam, the inner diameter of the movable opening is larger than the inner diameter of the fixed opening.
[0008] The anti-detachment mechanism includes an inner plate, an outer plate, a set of shafts, and a set of screws;
[0009] Both ends of the inner plate are provided with through openings, and both ends of the outer plate are provided with relief openings on the inner side. An installation opening is provided at the center of the relief opening.
[0010] One end of the shaft is fixed to the opening of the inner plate, and the other end of the shaft is provided with a threaded blind opening. The end of the shaft away from the inner plate is embedded in the relief opening, and the screw passes through the mounting opening and is threadedly connected to the threaded blind opening.
[0011] The anti-detachment mechanism is located at the lower part between two adjacent chain links. The inner plate and the outer plate are respectively attached to the inner and outer sides of the side beam of the chain link. The two shafts pass through the movable opening and the fixed opening on the two adjacent chain links respectively.
[0012] Furthermore, the link includes an end link, a plurality of first links and a plurality of second links, wherein the plurality of first links and second links are alternately connected to the tail end of the end link.
[0013] Furthermore, the side beam is an I-beam structure, and several reinforcing bars are provided on both sides of the side beam.
[0014] Furthermore, the top of the support plate is provided with several pressure plates by fasteners, and the spring plate is disposed between the support plate and the pressure plates on the chain link.
[0015] Furthermore, the outer end of the end link is connected to a connecting end, both ends of the side beam of the first link are provided with mounting positions, and both ends of the side beam of the second link and the inner end of the side beam of the end link are provided with arc-shaped openings.

The center point of the arc side of the torsion member is flush with the spring plate.
[0017] This utility model has the following beneficial effects:
[0018] This invention incorporates an anti-detachment mechanism between the various chain links that make up the derrick. By designing a large-diameter movable opening that cooperates with the shaft, a certain buffering capacity is provided, adding an extra layer of protection to the derrick body during production. This effectively avoids production accidents caused by the derrick body directly detaching due to the breakage of the spring plate. It can avoid significant production accident losses at a lower cost, and the newly added anti-detachment mechanism does not affect the original function of the derrick.
