Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings:
see fig. 1, a molten iron desulfurization spray gun changes device, including frame assembly 3, compression roller 4, side guide roller 6, bearing roller 7, shifting arm 5, pneumatic cylinder 2 be equipped with compression roller 4, side guide roller 6 and bearing roller 7 on the frame assembly 3, shifting arm 5 walks between compression roller 4, side guide roller 6 and bearing roller 7, pneumatic cylinder 2 installs on frame assembly 3, and pneumatic cylinder 2's piston rod is articulated with shifting arm 5 the front end of shifting arm 5 is equipped with notch 8, notch 8 and spray gun pipe diameter phase-match.
Frame assembly 3 includes two portals, and the portal lower part is equipped with cross arm 10, and the cross arm 10 of two portals 3 is connected through two parallel arrangement's type steelframe 13, sets up bearing roller 7 in the upper end of type steelframe 13, sets up compression roller 4 at the lower extreme of portal upper beam, sets up side deflector roll 6 on the inside arm of portal.
The press roller 4, the side guide roller 6 and the carrier roller 7 are used for positioning, supporting and guiding the traveling of the movable arm 5.
The hydraulic cylinder 2 is provided with a small hydraulic station 1 for providing a power source for the hydraulic cylinder 2. The hydraulic cylinder 2 is a middle swing type hydraulic cylinder, rotating shafts are fixed on two sides of the middle of the hydraulic cylinder, the rotating shafts are installed on two type steel frames 13 of the frame assembly 3 through bearing seats, and the head of the hydraulic cylinder 2 is hinged to the moving arm 5.
The frame assembly 3 is mounted to the platform by anchor bolts and is used for mounting and supporting other components.
The moving arm 5 is of a welding structure and is mainly formed by welding H-shaped steel, a steel plate is welded at the front end of the moving arm, and a notch 8 is formed in the steel plate and used for replacing a spray gun. Two arc-shaped notch bosses 9 are arranged on the upper end face of the steel plate and on two sides of the notch 8, and the inner diameter of a semicircle formed by the arcs of the two notch bosses 9 is matched with the outer diameter of the spray gun supporting plate 11. When the lance tube 12 is inserted into the slot 8 and the lance holder 11 is dropped onto the steel plate at the front end of the moving arm 5, the two slot bosses 9 just catch the outside of the lance holder 11. Preventing the lance from swinging out of the slot 8 due to inertia during the transfer process. Pin holes 14 are provided at the front end of the notch 8 and on both sides of the moving arm.
As shown in fig. 2 to 5, a method for using a molten iron desulphurization lance replacement device includes the following steps:
1) before starting the lance replacement operation, the lance is first lifted to a lance replacement position by a lifting device (see fig. 2).
2) The gun changer then starts to operate and the moving arm 5 is advanced to the gun position by the hydraulic cylinder 2 so that the barrel 12 fits into the slot 8 (see fig. 3).
