The utility model aims at realizing through the following technical scheme: a steel plate lifting hook comprises a lifting hook body, wherein a first through hole and a second through hole are formed in the lifting hook body, a first rack and a second rack are respectively connected in the first through hole and the second through hole in a sliding mode, a transmission gear which is meshed with the first rack and the second rack simultaneously is arranged between the first rack and the second rack, and the transmission gear is rotationally connected to the lifting hook body; the upper end of the first rack is connected with a sling, the lower end of the second rack is provided with a pressing plate for pressing a steel plate, and the pressing plate is opposite to the steel plate.

The utility model discloses when using, the steel sheet is placed between clamp plate and lifting hook body, and at the handling in-process, thereby first rack can receive the ascending pulling force rebound of hoist cable, first rack with remove the in-process, drive the second rack through drive gear and remove down mutually, thereby second rack area movable platen moves down and compresses tightly the steel sheet, the steel sheet is difficult for taking place relative slip with the lifting hook at the handling in-process like this, the steel sheet is more stable at the handling in-process, the security is higher.

Preferably, the first and second racks are parallel to each other.

Preferably, one side of the first rack close to the transmission gear is provided with a first transmission tooth, one side of the second rack close to the transmission gear is provided with a second transmission tooth, and the first transmission tooth and the second transmission tooth are respectively meshed with the transmission gear.

Preferably, the lifting hook body is provided with a gear seat, and the transmission gear is rotatably connected to the gear seat.

Preferably, the gear seat comprises two support plates which are arranged in parallel, the two support plates are fixed on the lifting hook body, a gear shaft is arranged between the two support plates, and the transmission gear is rotatably connected to the gear shaft.

Preferably, a rubber pad is arranged on one side of the pressing plate facing the steel plate. On one hand, the rubber pad is soft, so that scratches on the surface of the steel plate caused by direct contact between the pressing plate and the steel plate can be avoided; on the other hand, the rubber pad can increase the friction force between the steel plate and the rubber pad, so that the steel plate is not easy to slide relatively between the pressing plates.

Preferably, one end of the first rack connected with the sling is provided with a shackle. The shackle can facilitate connection and disconnection between the lifting hook and the sling.

The utility model has the advantages that: the utility model discloses a turn into the packing force to the steel sheet with the pulling force of hoist cable for steel sheet handling in-process is difficult for taking place relative slip with the lifting hook, and the steel sheet is more stable at the handling in-process, and the security is higher.
