Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy casting, and more particularly to a leak-stopping device with replaceable size. Background Art

[0002] The mold is a continuous steel casting machine that receives molten metal from the tundish and solidifies it into a solid shell with a specified cross-sectional shape. It is the most critical component of a continuous casting machine, and its structure, material, and performance parameters play a decisive role in the quality of the cast strands and the production capacity of the casting machine.

[0003] During the aluminum alloy casting process, aluminum leakage is a highly dangerous condition, requiring the mold to be plugged. Failure to promptly plug the leak can result in large amounts of hot molten aluminum leaking into the cooling water, posing an explosion risk. Workers typically have to manually fill the mold with asbestos, a time-consuming process that can also pose a safety risk of burns.

[0004] Therefore, a leak-stopping device with a replaceable size is badly needed. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a leak-stopping device with replaceable size to solve the problems in the background technology.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows.

[0007] A leak-plugging device with interchangeable sizes comprises a connecting rod, the top end of which is provided with a handle arranged perpendicularly to the connecting rod; a thread is provided on the side wall of the bottom end of the connecting rod, and a coaxially arranged iron plug is fitted on the thread; the iron plug is conical and wrapped with an asbestos plug; a circular ring is turned out from the middle of the connecting rod to form a sliding portion, the radius of the sliding portion is smaller than the radius of other parts of the connecting rod, and a compacting mechanism is provided on the sliding portion to increase stability.

[0008] To further optimize the technical solution, the compacting mechanism includes a sleeve sleeved on the sliding part, and the length of the sleeve is smaller than the length of the sliding part; the sleeve is connected to a number of inclined rods extending toward the bottom of the connecting rod and spreading away from the axis of the connecting rod, and the other end of the inclined rod is connected to a pressure ring coaxially arranged with the connecting rod for pressing the circular surface of the bottom end of the asbestos plug.

[0009] To further optimize the technical solution, the radius of the pressure ring is smaller than the radius of the bottom circle of the iron plug.

[0010] To further optimize the technical solution, the length of the asbestos plug is greater than that of the iron plug, the portion of the asbestos plug that exceeds the iron plug is located at one end of the bottom circle, and the portion of the asbestos plug that exceeds the iron plug is bent to wrap the iron plug.

[0011] To further optimize the technical solution, a rubber sleeve with threads is provided on the handle.

[0012] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is as follows.

[0013] The utility model provides a resizable plugging device, in which an iron plug is detachably mounted on a connecting rod to facilitate plugging. The size of the iron plug can also be flexibly changed according to the size of the crystallizer. The utility model has a simple structure and is easy to use, which can reduce the operator's operating time and risks, and facilitates plugging of crystallizer leaks.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] A plugging device with interchangeable size, combined with Figures 1 to 2 As shown, it includes a handle 1, a connecting rod 2, an iron plug 3, an asbestos plug 4, a thread 5, a sliding part 6, an inclined rod 7, and a pressure ring 8.

[0019] A handle 1 is provided at the top end of the connecting rod 2 and is arranged perpendicular to the connecting rod 2; a rubber sleeve with a thread 5 is provided on the handle 1 to increase the convenience and comfort of use.

[0020] The bottom sidewall of the connecting rod 2 is provided with a thread 5, fitted with an iron plug 3 coaxially arranged with the connecting rod 2. The iron plug 3 is conical and wrapped with an asbestos plug 4 for sealing leaks. The asbestos plug 4 is longer than the iron plug 3, and the portion of the asbestos plug 4 that extends beyond the iron plug 3 is located at the rounded end of the bottom surface. The portion of the asbestos plug 4 that extends beyond the iron plug 3 is bent and wrapped around the iron plug 3.

[0021] A circular ring is turned out from the middle of the connecting rod 2 to form a sliding portion 6. The radius of the sliding portion 6 is smaller than the radius of other parts of the connecting rod 2. A compacting mechanism for increasing stability is sleeved on the sliding portion 6.

[0022] The compacting mechanism includes a sleeve 9 that fits over the sliding portion 6 and is shorter than the sliding portion 6. Connected to the sleeve 9 are several inclined rods 7 that extend toward the bottom of the connecting rod 2 and spread out away from the axis of the connecting rod 2. The other ends of the inclined rods 7 are connected to a pressure ring 8 that is coaxial with the connecting rod 2 and is used to press the bottom circular surface of the asbestos plug. The radius of the pressure ring 8 is smaller than the radius of the bottom circular surface of the iron plug 3.

[0023] In actual use, the utility model is to install a threaded iron plug of appropriate size on the connecting rod, and then wrap an asbestos plug of corresponding size on the iron plug. The asbestos plug is longer than the iron plug, and the excess part is folded and wrapped around the bottom circular surface of the iron plug. Then, the sleeve 9 is slid along the sliding part, so that the pressure ring presses the bottom circular surface of the asbestos plug to prevent it from falling off. The device is inserted into the crystallizer by the handle to achieve rapid plugging.

[0024] When replacing an iron plug, you can press the tip of the plug against an object, then push the sleeve in the direction of the tip so that the pressure ring is pressed against the bottom circular surface of the asbestos plug, and then rotate the connecting rod to separate the connecting rod and the plug. This can be done by one person, and there is no need for two people to work together for disassembly.
