Technical Field

[0001] The present invention relates to the technical field of forklift attachments, and specifically to a forklift attachment for handling slag ladles. Background Art

[0002] In modern steel smelting, the slag ladle is one of the indispensable important devices in the smelting process. It is a high-temperature container that circulates between the converter and the slag treatment. At present, the circulation and transportation mostly use special slag transport vehicles, and most of the special slag transport vehicles rely on imports and are expensive. When using a forklift for circulation, there is no special attachment, and the safety is not good. There is currently a lack of a special attachment to cooperate with the forklift to achieve circulation. Summary of the Invention

[0017] At the front end of the lower bottom surface of each clamping arm, a pair of first support plates 222 are provided. In the middle of the lower bottom surface of the clamping arm, a pair of second support plates 223 are provided. The pair of first support plates 222 are located between the openings at the front end parts of the pair of side plates and are connected by a pin shaft.

[0018] One end of the piston rod of each tipping oil cylinder is located between the openings of the corresponding pair of second support plates 223 and is connected by a pin shaft. One end of the cylinder block of the tipping oil cylinder is located between the openings at the right-angle parts of the corresponding pair of side plates and is connected by a pin shaft.

After the pouring is completed; the tipping oil cylinder retracts to drive the slag ladle tail box to tip back to its original position. After the slag ladle tail box is transported to a suitable position, the mast is lowered to place the slag ladle tail box on the ground, and then the locking oil cylinder retracts, driving the clamping seat to move backward along the upper end surface of the clamping arm, releasing the copper column of the slag ladle tail box, and completing the work. Therefore, the forklift attachment for handling slag ladles of the present invention can be used in cooperation with a forklift to complete the tipping and resetting of the slag ladle, and solve the problems of transportation and tipping of the slag ladle in the smelting process.
