Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking continuous casting equipment, and particularly relates to a continuous casting dummy bar anti-falling device. Background Art

[0002] In the continuous casting process, the dummy bar chain usually adopts two types: bottom loading and top loading. When using the top loading type, a dummy bar anti-falling device must be set in the top loading dummy bar system.

[0003] After retrieval, a dummy bar anti-falling self-locking device with the publication number of CN212682383U belongs to the field of steelmaking continuous casting. The utility model includes a base, on which at least one set of locking modules and power modules are arranged. The locking module includes a support seat and a locking head distributed oppositely, and the area where the dummy bar is lifted through is between the support seat and the locking head; the locking head is hinged to the locking head support, and the locking head is connected to the power module. The power module is used to drive the locking head to turn in and out around the locking head support, so that the locking head and the support seat are relatively locked or separated. The utility model overcomes the problem that once the dummy bar is accidentally dropped during lifting in the prior art, which is likely to cause safety accidents, and can automatically lock the dummy bar, making it stop in the air waiting for accident handling. After the accident handling is completed, the locking of the dummy bar is automatically opened to prevent the dummy bar from falling and damaging equipment or causing personal safety accidents.

[0004] Regarding the above related technologies, the inventor believes that during the use of the above device, the distance between the locking head and the support seat is fixed and cannot be adjusted. When the thickness of the dummy bar is greater than or less than the rotation range of the locking head, it will cause the dummy bar to not be locked, and thus the device has certain limitations during use. For this reason, we propose a continuous casting dummy bar anti-falling device. Summary of the Utility Model

[0027] Embodiment 1

[0028] The present utility model provides an anti-falling device for a continuous casting dummy bar as shown in Figures 1-3 which includes a fixed seat 1. A clamping plate 2 is welded on one inner wall of the fixed seat 1. An anti-falling mechanism 3 is provided on the fixed seat 1. The anti-falling mechanism 3 includes a screw 9, a fixed frame 6 and a brake cam 7. The screw 9 is threadedly connected to the fixed seat 1. One end of the screw 9 is provided with a rotating seat 8, and the other end of the screw 9 is provided with a rotating head 10. The fixed frame 6 is arranged on the rotating seat 8, and the brake cam 7 is hinged to the fixed frame 6. The position of the brake cam 7 corresponds to that of the clamping plate 2.

[0029] A rotating rod is provided on the rotating head 10. The rotating rod and the rotating head 10 are of an integrated structure. A rubber sleeve is nested on the rotating rod, which can facilitate driving the rotating head 10 to rotate through the rotating rod, so as to facilitate driving the screw 9 to rotate, and can effectively improve the operation convenience.

[0030] The screw rod 9 is connected to the rotating end of the rotating seat 8, and the fixing frame 6 is connected to the fixed end of the rotating seat 8, which can prevent the fixing frame 6 from rotating following the rotation of the screw rod 9 and affecting the use effect.

[0031] A guiding groove 5 is provided on the inner wall of the fixed seat 1, and a guiding plate 11 is provided on the outer wall of the fixing frame 6. The fixing frame 6 is fitted and connected with the guiding groove 5 through the guiding plate 11, which can provide a limiting and guiding function and improve the stability of the fixing frame 6 during movement.

[0032] Both the guiding plate 11 and the guiding groove 5 are provided with two. The two guiding plates 11 are respectively fitted and connected with the two guiding grooves 5, which can provide a supporting effect on both sides of the fixing frame 6, thereby further improving the stability of the fixing frame 6 during movement.

[0033] Embodiment Two

[0034] On the basis of Embodiment One, as Figures 1-2 shown, a plurality of mounting seats 4 are welded on the outer wall of the fixed seat 1, and mounting holes are provided on the plurality of mounting seats 4, which can facilitate the installation of the fixed seat 1, and the plurality of mounting seats 4 can improve the installation stability.

[0035] Embodiment Three

[0036] On the basis of Embodiment One, as Figures 1-3 shown, anti-slip gaskets 12 are provided on the mating end faces of the brake cam 7 and the clamping plate 2. The anti-slip gaskets 12 are matched with the brake cam 7 and the clamping plate 2 in terms of size and structure, which can increase the friction between the brake cam 7 and the clamping plate 2 and improve the anti-falling effect.

[0037] Embodiment Four

[0038] On the basis of Embodiment One, as Figures 1-3 shown, a fixing plate 13 is provided on the brake cam 7, a mounting plate 14 is provided on the fixing frame 6, an electric cylinder 15 is installed on the mounting plate 14, a cross plate 16 is fixedly connected to the extending end of the electric cylinder 15, a guiding rod 17 is hinged on the fixing plate 13, the guiding rod 17 penetrates through the cross plate 16 and is fitted and connected with the cross plate 16, and a stop block 18 is welded on the penetrating end of the guiding rod 17. After providing the anti-falling function, the brake cam 7 can be rotated by the electric cylinder 15, so that the brake cam 7 can be separated from the dummy bar, facilitating the lifting operation of the dummy bar.

[0039] Both the fixing plate 13 and the guiding rod 17 are provided with two. The two fixing plates 13 are symmetrically arranged on the brake cam 7, and the two guiding rods 17 are symmetrically distributed on the cross plate 16, which can improve the stability and safety during use.

[0040] During use, first adjust the position of the brake cam 7 according to the thickness of the dummy bar. When adjusting, rotate the rotating rod to drive the rotating head 10 and the screw rod 9 to rotate. Since the screw rod 9 is threadedly connected to the fixed frame 6 and the screw rod 9 is connected to the fixed frame 6 through the rotating seat 8, the screw rod 9 can drive the fixed frame 6 to move during rotation, so that the position of the brake cam 7 can be adjusted until it corresponds to the thickness of the dummy bar. After the adjustment is completed, it can be used normally. During use, when the dummy bar falls, the brake cam 7 will rotate downward and lock under the action of friction to lock the dummy bar and prevent it from falling. When the dummy bar is fixed by an external force, the electric cylinder 15 can be started to drive the guide rod 17 to move. The guide rod 17 can drive the brake cam 7 to rotate upward during movement, so that it is separated from the dummy bar, facilitating the continuous lifting operation of the dummy bar.
