Description

Technical Field

[0001] The utility model relates to an anti-slip and anti-retrograde device for a continuous casting dummy bar, belonging to the technical field of iron and steel smelting equipment. Background Art

[0002] Before continuous casting starts, when the dummy bar is in the straightening machine, there may still be operators working on the input roller table or the lifting roller table. If there is a misoperation and the straightening machine lifts or the brake of the straightening machine fails, the dummy bar may slide down from above, causing fatal injuries to the operators. Therefore, there is an urgent need for an anti-slip and anti-retrograde device for the dummy bar that is safe, reliable, and does not affect the maintenance of the continuous casting roller table equipment. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an anti-slip and anti-retrograde device for a continuous casting dummy bar according to the above-mentioned prior art, which is convenient to operate, safe and reliable, does not affect the forward and backward movement of the continuous casting billet and the dummy bar, and can prevent the dummy bar from slipping, ensuring the personal safety of the operators.

[0004] The technical solution adopted by the utility model to solve the above problems is as follows: an anti-slip and anti-retrograde device for a continuous casting dummy bar, including a anti-retrograde seat, the anti-retrograde seat is arranged between the straightening machine and the conveying unit; a lifting seat is arranged at the bottom of the anti-retrograde seat, driving the lifting seat to make a lifting movement, driving the anti-retrograde seat to lift synchronously, so that the anti-retrograde seat can be switched between a low position and a high position. When the anti-retrograde seat is in the high position, the anti-retrograde seat is higher than the conveying unit and has a supporting and limiting effect on one end of the dummy bar. When the anti-retrograde seat is in the low position, the anti-retrograde seat is lower than the conveying unit.

[0005] The conveying unit includes a plurality of conveying roller wheels arranged at equal intervals, and the anti-retrograde seat is arranged between the straightening machine and the first conveying roller wheel.

[0006] When the anti-retrograde seat is in the low position, the anti-retrograde seat is lower than the upper roller surface of the first conveying roller wheel.

[0007] A vertically arranged lifting oil cylinder is arranged at the bottom of the lifting seat, the extending end of the lifting oil cylinder is fixedly connected to the lifting seat, and the cylinder body of the lifting oil cylinder is fixed to the fixing plate.

[0008] Compared with the prior art, the advantages of the utility model are as follows: an anti-slip and anti-retrograde device for a continuous casting dummy bar is provided with an anti-retrograde seat between the straightening machine and the conveying unit, and the lifting oil cylinder adjusts the height of the anti-retrograde seat to realize the switching operation of the anti-retrograde seat between the low position and the high position, which does not affect the forward and backward movement of the continuous casting billet and the dummy bar, and can prevent the dummy bar from slipping, ensuring the personal safety of the operators, convenient to operate, safe and reliable.

[0011] In the figure, 1 is the dummy bar, 2 is the conveying roller, 3 is the anti-retrograde seat, 4 is the lifting seat, 5 is the lifting oil cylinder, and 6 is the fixed plate. Specific implementation mode

[0012] The present utility model will be further described in detail below in conjunction with the embodiments of the accompanying drawings.

[0013] As Figure 1 、 2 shown, an anti-slip and anti-retrograde device for a continuous casting dummy bar in this embodiment includes an anti-retrograde seat 3, and the anti-retrograde seat 3 is arranged between the straightening machine and the conveying unit. The conveying unit includes a plurality of conveying rollers 2 arranged at uniform intervals, and the anti-retrograde seat 3 is arranged between the first conveying roller and the straightening machine. A lifting seat 4 is arranged at the bottom of the anti-retrograde seat 3, and a vertically arranged lifting oil cylinder 5 is arranged below the lifting seat 4. The cylinder end of the lifting oil cylinder 5 is fixed on the fixed plate 6, and the extending rod of the lifting oil cylinder 5 is fixedly connected to the lifting seat 4. The lifting oil cylinder 5 drives the lifting seat 4 to perform lifting motion, driving the anti-retrograde seat 3 to lift synchronously, so that the anti-retrograde seat 3 can be switched between a low position and a high position. That is, when the anti-retrograde seat is in the high position, the anti-retrograde seat is higher than the conveying roller and has a supporting and limiting effect on one end of the dummy bar, preventing the dummy bar from sliding to the conveying roller and ensuring the personal safety of the operators during the maintenance of the conveying roller path; when the anti-retrograde seat is in the low position, the top of the anti-retrograde seat is lower than the upper roller surface of the conveying roller, and does not affect the forward and backward movement of the billet and the dummy bar.

[0014] An anti-retrograde seat is arranged between the straightening machine and the conveying unit, and the height of the anti-retrograde seat is adjusted by the lifting oil cylinder, realizing that the anti-retrograde seat can be switched between a low position and a high position for operation, which neither affects the forward and backward movement of the continuous casting billet and the dummy bar, nor prevents the dummy bar from slipping, ensuring the personal safety of the operators, with convenient operation, safety and reliability.

[0015] In addition to the above embodiments, the present utility model also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present utility model.
