The utility model discloses a realize above-mentioned technical purpose through following technological means.

A steel billet hot conveying device comprises a steel tilting machine slide rail, a cooling bed, a fixed slide rail and a movable pull rod; a fixed slide rail is arranged between the slide rail of the tilting gear and the fixed tooth of the cooling bed, a movable pull rod is arranged at one end of the movable tooth of the cooling bed, and the movable pull rod is made to move repeatedly and periodically through the repeated periodic movement of the movable tooth and the fixed tooth of the cooling bed; the steel hooking machine is used for conveying steel billets to the fixed slide rails, and the steel billets are closed on the fixed slide rails through the movable pull rods.

Furthermore, the material of the fixed slide rail and the material of the movable pull rod are both heat-resistant materials.

Furthermore, the movable pull rod is L-shaped.

And the travelling crane clamp is positioned above the fixed slide rail, and a plurality of steel billets close to the fixed slide rail are hoisted to the steel billet vehicle together through the travelling crane clamp.

The beneficial effects of the utility model reside in that:

1. steel billet heat send device, through fixed slide rail and activity pull rod respectively with the cold bed move the tooth with decide the tooth and be connected, through the tooth that moves of cold bed with decide tooth repeated cycle motion, make activity pull rod repeated cycle motion, and then make a plurality of steel billets draw close on fixed slide rail, avoid the temperature reduction of single steel billet in the transportation too fast.

2. Steel billet heat send device, through at the fixed slide rail of cold bed front portion installation and activity pull rod, can avoid causing the loss of temperature through the cold bed transportation.

3. Steel billet heat send device, guarantee that many steel billets can be drawn together at the cold bed head, directly roll off the production line through driving clamp, improve the steel billet temperature of rolling off the production line.

Detailed Description

The invention will be further described with reference to the drawings and the following examples, but the scope of the invention is not limited thereto.

As shown in fig. 1, the steel billet hot conveying device of the present invention comprises a steel tilting machine slide rail 3, a cooling bed, a fixed slide rail 1 and a movable pull rod 2; in the prior art, after a continuous casting machine conveys a steel billet to a slide rail 3 of a tilting gear, a steel hooking machine conveys the steel billet to the front end of a cooling bed. The utility model discloses the main inventive point is that installation fixed slide rail 1 and activity pull rod 2 between tilting gear slide rail 3 and cold bed, as shown in fig. 2 and fig. 3, specifically are: a fixed sliding rail 1 is welded and installed between the steel turnover machine sliding rail 3 and the fixed teeth 4 of the cooling bed, a movable pull rod 2 is welded and installed at one end of the movable teeth 5 of the cooling bed, and the movable pull rod 2 is made to make repeated periodic motion through the repeated periodic motion of the movable teeth 5 and the fixed teeth 4 of the cooling bed; the steel hooking machine 7 is used for conveying steel billets onto the fixed slide rail 1, and the steel billets are closed on the fixed slide rail 1 through the movable pull rod 2. The fixed slide rail 1 and the movable pull rod 2 are both made of heat-resistant materials. The movable pull rod 2 is L-shaped. Through fixed slide rail 1 and activity pull rod 3 respectively with the cold bed move the tooth 5 with decide tooth 4 and be connected, through the cold bed move tooth 5 with decide 4 repeated periodic motions of tooth, make 3 repeated periodic motions of activity pull rod, and then make a plurality of steel billets draw close on fixed slide rail, avoid single steel billet temperature reduction in the transportation too fast.
