Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a slab transporting crane. Background Art

[0002] Slab handling cranes are indispensable material handling equipment in the continuous casting and rolling process, and are specially used to handle high-temperature slabs under extreme conditions. Such lifting equipment must operate reliably in a harsh environment with full load, high temperature and high dust to ensure that the newly formed red-hot steel billets can be transferred to the cooling area in time. Due to the particularity of the working environment, especially in the face of continuous high temperature, traditional slab handling cranes are no longer competent, especially the towing cable system of the crane trolley, which often cannot work normally under such high temperature conditions.

[0003] A Chinese patent (publication number: CN212450314U) discloses a water circulation insulation device for a metallurgical crane; the patent includes a high-temperature resistant hose, a stainless steel spherical cooling body, and a water collecting tank. The high-temperature resistant hose is laid at the bottom of the crane main beam, and each high-temperature resistant hose is separated by a partition and fixed to the fixing plate and the crane main beam by bolts; the patent can only cool the crane main beam and cannot protect the towing cable.

[0010] Preferably, an arc-shaped supporting groove plate is provided at the position of the hook corresponding to the water-cooling cable.

[0011] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0012] The utility model discloses a slab handling crane with a simple structure and is easy to assemble; the cable bridge is in a trough-shaped structure, an anti-radiation plate is provided on the outer side thereof, and a heat insulation plate is provided between the anti-radiation plate and the cable bridge; the cable bridge mainly plays a role in protecting the water-cooled cable, and the anti-radiation plate and the heat insulation plate on the outer side of the cable bridge can play a role in heat insulation barrier, further improving the reliability of the water-cooled cable and extending the service life of the water-cooled cable.

[0013] The utility model has a plurality of cables wrapped with a metal mesh on the outside of the cooling water pipe body, and the metal mesh is wound and connected to the cooling water pipe body, that is, multiple layers of metal mesh can be wound around the cooling water pipe first, and then the metal mesh can be wrapped around the plurality of cables. On the one hand, the metal mesh can make the cables and the cooling water pipe close to each other, and on the other hand, the metal mesh can be used as a heat-conducting medium to further improve the heat exchange efficiency; the cooling water pipe and the cable are independent of each other, so that the length of the water-cooled cable can be cut according to actual needs. After cutting, the end of the cooling water pipe and the end of the cable are independently connected to each other, which can facilitate the connection of the cooling water pipe to the cooling circulating water source and the connection of the cable to the mains without the need to make a special joint.

[0014] The utility model provides an arc-shaped supporting groove plate at the position corresponding to the water-cooling cable of the hook. The water-cooling cable is hung in the groove of the arc-shaped supporting groove plate. The curvature of the arc-shaped supporting groove plate is used to limit the bending angle of the water-cooling cable, thereby preventing the water-cooling cable from being excessively bent, causing the cooling water pipe to bend and collapse, and causing the cooling circulating water flow in the cooling water pipe to be blocked.

[0019] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0021] The cable tray 3 is a trough-shaped structure with an anti-radiation plate on its outside and a heat insulation plate between the anti-radiation plate and the cable tray 3; the cable tray 3 mainly serves to protect the water-cooled cable 4, and the anti-radiation plate and heat insulation plate on the outside of the cable tray 3 can serve as a heat insulation barrier, further improving the reliability of the water-cooled cable 4 and extending the service life of the water-cooled cable 4.

On the one hand, the metal mesh 4-2 can make the cables 4-3 and the cooling water pipe 4-1 close to each other, and on the other hand, the metal mesh 4-2 can be used as a heat-conducting medium to further improve the heat exchange efficiency. Preferably, the metal mesh 4-2 can wrap the cooling water pipe 4-1 and the cable 4-3 in a spiral winding manner. The cooling water pipe 4-1 and the cable 4-3 are independent of each other, so that the length of the water-cooled cable 4 can be cut according to actual needs. After cutting, the end of the cooling water pipe 4-1 and the end of the cable 4-3 are independently connected, which can facilitate the cooling water pipe 4-1 to be connected to the cooling circulation water source, and the cable 4-3 to be connected to the mains, without the need to make a special joint.
