Detailed ways

As shown in Figure 1, the turning structure of the smelting furnace includes hydraulic cylinder support 2, hydraulic cylinder intermediate pin support 3, hydraulic cylinder 5, bracket 7, joint bearing seat 8 and rotary support 9, on the side of foundation 1 The hydraulic cylinder support 2 is arranged on the upper boss, and the hydraulic cylinder support 2 is welded by a bottom plate and two lug plates. On the bottom plate, the lug plate is provided with a shaft hole matching the shaft. The shaft holes on the two lug plates are concentric and have the same diameter. A shaft is installed in the shaft hole. The piston rod of the hydraulic cylinder is supported on the shaft, that is, the hydraulic cylinder The piston rod is hinged with the hydraulic cylinder support through the rotating shaft; the middle pin support 3 of the hydraulic cylinder is fixed on the beam steel 4 at the bottom of the furnace body, and the middle pin support 3 of the hydraulic cylinder is welded by a bottom plate and two lug plates. There are two bolt through holes on the bottom plate for connecting with the beam steel at the bottom of the furnace body, and there are shaft holes on the lug plates that match the pin shafts in the middle of the cylinder barrel of the hydraulic cylinder. The shaft holes on the two lug plates are concentric, and the shaft The hole diameters are the same, and the pin shaft in the middle of the cylinder of the hydraulic cylinder is placed in the shaft hole, that is, the cylinder of the hydraulic cylinder is hinged with the steel structure of the furnace body; a rotary support 9 is arranged on the edge boss on the other side of the foundation, The slewing support 9 is opposite to the hydraulic cylinder support 2. There is a shaft hole on the lug plate of the slewing support, and a pin shaft is installed in the shaft hole. The joint bearing seat 8 is supported on the pin shaft. The side of the joint bearing seat 8 is in contact with the furnace. The body shape steel is connected, and the top surface of the joint bearing seat is connected with the bottom surface of the support 7, and the side of the support 7 is fixed with the furnace body profile steel, so that the joint bearing seat 8 is hinged with the rotary support 9 by a pin.

In specific applications, when the furnace body 6 needs to be turned over, the piston rod of the hydraulic cylinder 5 is pushed out. Axle support 3 does flipping motion together. When the furnace body is not tilting, the hydraulic cylinder does not bear the load.
