Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing：
See Fig. 1, a kind of molten iron desulfuring spray gun more changing device, including frame assembly 3, pressure roller 4, side deflector roll 6, carrying roller 7, movement
Arm 5, hydraulic cylinder 2, the frame assembly 3 on be equipped with pressure roller 4, side deflector roll 6 and carrying roller 7, the moving arm 5 walk in pressure roller 4,
Between side deflector roll 6 and carrying roller 7, the hydraulic cylinder 2 is installed in frame assembly 3, and the piston rod and moving arm 5 of hydraulic cylinder 2 are hinged,
It is equipped with notch 8 in the front end of the moving arm 5, the notch 8 matches with spray gun pipe diameter.
The frame assembly 3 includes two door frames, and door frame lower part is equipped with cross-arm 10, and the cross-arm 10 of two door frames 3 passes through two
A shaped steel frame disposed in parallel 13 connects, and carrying roller 7 is arranged in the upper end of shaped steel frame 13, and pressure roller 4 is arranged in the lower end of door frame upper beam,
Side deflector roll 6 is set in the inner webs of door frame.
Pressure roller 4, side deflector roll 6 and carrying roller 7 are used for positioning, support and the guiding of 5 traveling of moving arm.
Hydraulic cylinder 2 is furnished with small-sized hydraulic station 1, for providing power source for hydraulic cylinder 2.Hydraulic cylinder 2 is middle part swing type liquid
Cylinder pressure, in the middle part of two sides be fixed with rotation axis, rotation axis is installed on two shaped steel frames 13 of frame assembly 3 by bearing block
On, 2 head of hydraulic cylinder and moving arm 5 are hinged.
Frame assembly 3 is installed on platform by foundation bolt, it is used for the installation and support of other component.
Moving arm 5 is welding structure, is mainly welded by H profile steel, and front end is welded with steel plate, and notch 8 is arranged on steel plate,
For exchanging spray gun for.The notch boss 9 there are two arc, two notch boss 9 are set in the upper surface of steel plate, the two sides of notch 8
The outer diameter of the internal diameter and spray gun supporting plate 11 of semicircle that is constituted of arc match.When lance tube 12 is embedded in notch 8, spray gun supporting plate
11 when falling on the steel plate of 5 front end of moving arm, and two notch boss 9 just block the outside of spray gun supporting plate 11.Prevent spray gun
Since bobbing deviates from notch 8 during transfer.There is pin hole 14 on the front end of notch 8, the two sides of moving arm.
As Figure 2-Figure 5, the application method of a kind of molten iron desulfuring spray gun more changing device, the specific method is as follows：
