The utility model provides a technical scheme that its technical problem adopted as follows:
a safety hook of a crane comprises a hook body; a supporting plate is arranged in a hook groove of the lifting hook body, the supporting plate is connected with the hook groove through a spring and a positioning rod, an accommodating groove is formed in the hook groove of the lifting hook body, and the accommodating groove is located right below the supporting plate; one end of the spring and one end of the positioning rod are both arranged in the accommodating groove, the spring is arranged on one side of the positioning rod, and the other end of the positioning rod is hinged with the supporting plate; the layer board is the arc structure, and the lower extreme of this layer board is equipped with the trip, and the hook inslot of lifting hook body is equipped with the spacing arch that is located storage tank one side, and the upper end of layer board is towards this spacing arch and can support and hold on this spacing arch.
Further, the lifting hook body is provided with a guide mechanism on the surface, the guide mechanism comprises fixing rods, guide rods and side rods, the number of the fixing rods is two, the fixing rods are respectively arranged on two opposite sides of the lifting hook body, the guide rods and the side plates are respectively arranged between the two fixing rods and are respectively connected with the two fixing rods, and a moving space for accommodating the supporting plate is formed between the guide rods and the side plates.
Furthermore, rollers capable of freely rolling are arranged on the guide rod and the side rods.
The utility model has the advantages that:
(1) the utility model discloses hang the heavy object on the layer board and be in the lower extreme department of layer board, remove to the storage tank after layer board lower extreme department atress, again because locating lever and layer board are articulated, so can know by lever principle, the upper end of layer board will move towards spacing arch, finally with this body contact of lifting hook and lie in spacing bellied inboard, layer board and spacing arch support each other this moment, spacing arch forms spacingly to the layer board, thereby seal the opening of lifting hook, can not drop with guaranteeing that the heavy object, improve the security greatly, and the lower extreme at the layer board has set up the trip, hang on the layer board all the time with guaranteeing the heavy object, thereby prevent that the heavy object from breaking away from the layer board.
(2) The utility model discloses a normal operating trajectory of layer board is guaranteed to guiding mechanism to the upper end of guaranteeing the layer board can be replaced and held on spacing arch.
(3) The utility model discloses a cylinder that can freely roll can carry on spacingly to the layer board, also can prevent that layer board and guiding mechanism from taking place the friction to guarantee normal rotation.
