[0002] The national standard seamless steel pipe is made of steel ingots or solid tubes through perforation to form rough tubes, and then hot rolled, cold rolled or cold drawn. The national standard steel pipe has an important position in the domestic steel pipe industry. The raw material for rolling the national standard steel pipe is round tube billets. The round tube billets must be cut by a cutting machine to be a billet with a length of about 1 meter, and then sent to the furnace for heating via a conveyor belt. In the production workshop, the round tube billets need to be moved from the stacking position to the cutting station. For this reason, the handling operation of the round tube billets needs to be completed in the workshop. Most of the existing ones use forklifts or mobile racks, and then the racks for placing pipes are set on both sides of the mobile racks. However, in this way, the materials to be transported are less, and during the handling process, the operator needs to board the forklift or mobile rack, which consumes a lot of manpower. For this reason, a raw material handling equipment for seamless steel pipe production with a large handling capacity and no human assistance is designed to complete the operation of moving up and down the round tube billets, improve the handling efficiency and reduce the labor of the labor force.
