Description

Technical Field

[0001] This utility model belongs to the field of continuous casting technology in iron and steel metallurgy, and in particular relates to a stopper rod mechanism for preventing slippage. Background Technology

[0002] The continuous casting machine adjusts the steel flow by controlling the opening degree of the stopper rod installed on the stopper rod mechanism, so as to achieve the purpose of stable and safe production of the liquid level in the crystallizer. The existing stopper rod mechanism is installed at the end of the mounting arm. The end of the mounting arm is equipped with a U-shaped groove structure or a hook-shaped groove to facilitate the stopper rod to be moved from the side to the mounting position for positioning and insertion. It is then tightened by the nut fastener carried on the stopper rod.

[0003] During the production process, as the stopper rod vibrates continuously, the connecting parts on the stopper rod may become loose, causing the stopper rod to move left and right within the mounting arm. When it moves to the end of the stopper rod's horizontal arm hook, without special protection, the stopper rod connecting parts and the stopper rod will slip off from the end of the mechanism's horizontal arm hook, causing the continuous casting to stop. In severe cases, this can lead to overflow steel and a serious accident that interrupts continuous casting production, posing a safety hazard.

[0004] Therefore, designing an anti-slip stopper mechanism is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this utility model is to provide a stopper rod anti-slip mechanism. By opening a hole in the U-shaped groove and cooperating with the design of the anti-slip component, the outer wall of the sleeve contacts the peripheral side of the stopper rod, which can protect the stopper rod from slipping, achieve the purpose of stable production, improve production safety, and at the same time, it is convenient and quick to install and disassemble without affecting the normal use and replacement of the stopper rod.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a stopper rod mechanism for preventing slippage, including a mounting arm, a stopper rod body and an anti-slip component. One end of the mounting arm is provided with a U-shaped groove, and the stopper rod body is disposed in the U-shaped groove.

[0008] An annular opening is provided on one side of the U-shaped groove, and a T-shaped opening is provided on the other side of the U-shaped groove, with the larger end of the T-shaped opening facing inward;

[0009] The anti-detachment component includes a sleeve and a screw;

[0010] One end of the sleeve is gapped inside the large end of the T-shaped through-hole, and the other end of the sleeve passes through the annular through-hole and is fixed with a nut. The sleeve is movably connected to the T-shaped through-hole and the annular through-hole.

[0011] One end of the screw is provided with a screw head, and the other end of the screw passes through the small end of the T-shaped opening, the sleeve and the nut in sequence and is threadedly connected to the nut;

[0012] The sleeve is fixed in the U-shaped groove by a screw and a nut, and the peripheral side of the sleeve is in contact with the peripheral side of the stopper body.

[0013] Furthermore, the stopper rod body is provided with fasteners, and the gap of the stopper rod body is set in the U-shaped groove and fixed to the mounting arm by the fasteners.

[0014] Furthermore, the screw head is an external hexagonal screw head, the nut is an external hexagonal nut, and the nut and screw head have the same specifications.

[0015] Furthermore, the screw is provided with a threaded section and a smooth section, with the threaded section located at the end of the screw.

[0016] Furthermore, the sleeve has a necked section on its peripheral side, and a soft sleeve is fitted over the necked section.

[0017] Furthermore, gaskets are provided between the nut and screw head and both sides of the U-shaped groove.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by opening a hole in the U-shaped groove and combining it with the design of an anti-detachment component, allows the outer wall of the sleeve to contact the peripheral side of the stopper rod, thereby preventing the stopper rod from detaching, achieving the purpose of stable production, improving production safety, and at the same time, it is convenient and quick to install and disassemble without affecting the normal use and replacement of the stopper rod.

[0020] 2. This utility model, through the design of a novel anti-loosening component, compared with the ordinary bolt structure, adds a sleeve structure to the nut. The two ends of the sleeve interfere with the two sides of the U-shaped groove through the annular through-hole and T-shaped through-hole, which improves the positional strength of the anti-loosening component. At the same time, the threaded section is protected by the sleeve during installation and anti-loosening process, so that the thread will not be damaged, thus ensuring the service life of the anti-loosening component.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
