The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, a kind of Mobile spray gun device comprises sprocket wheel 1, chain 2, support 3, slide block 4, driver part 5, spray gun 10, bearing 11;
Bearing 11 is fixedly welded on 12 outsides, high temperature furnace wall, support 3 one ends are fixed on the bearing 11, the other end is equipped with driver part 5, on driver part 5 and near the support 3 of bearing 11, be provided with sprocket wheel 1, at sprocket wheel 1 chain 2 is installed, be connected with slide block 4 on the chain 2, slide block 4 is installed in the chute 13 of support 3, and spray gun 10 is connected on the slide block 4.
2 motions of driver part 5 chain drive-belts with moving in the chute of movable slider 4 on support 3, drive spray gun 10 and move forward and backward.
The type of attachment that described slide block 4 is connected with chain is: slide block 4 pin-ended points connect by securing member 9 with the chain 2 that is connected the part chain link.
Described slide block 4 is to be installed in the chute of support 3 by roller 7, and slide block 4 and roller 7 are by securing member 9 and regulate pad 14 and carry out fastening.Guarantee that by the position of fine setting adjusting pad 14 and the center of sprocket wheel 1 roller 7 moves freely in chute, unlikely stuck.
Described slide block 4 is provided with half slot 15, and spray gun 10 is installed on the arc groove 15 by pipe clamping pieces 8, and pipe clamping pieces 8 is connected by securing member 9 with slide block 4.
But described driver part 5 adopts the driver part of rotating.
Be provided with approach switch 6 at support 3.Slide block 4 and securing member 9 are synchronized with the movement, the working range of Field adjustment size A(approach switch) and the horizontal range of approach switch 6 on support 3, can adjust the distance that spray gun 10 entered and extracted out burner hearth, behind approach switch 6 location positionings, be fixed on the support 3 with nut.
After the utility model Mobile spray gun device installs at the scene, utilize reversible driver part 5 to drive advancing of slide blocks 4 and retreat, thereby drive the front and back operation of spray gun 10.When the degree of depth that enters burner hearth when spray gun 10 meets the demands, by detecting near the displacement between 6 pairs of securing members 9 of approach switch of burner hearth, in time send signal to electric-control system, cut off driver part 5, realize spray gun 10 auto-feeds, the function that stops; When spray gun 10 stops to spray or when unusual condition is arranged, 5 counter-rotatings of system triggers driver part, spray gun 10 is in time withdrawn from high temperature furnace away from burner hearth.During spray gun 10 rollback, cut off driver part 5 by the approach switch 6 that is arranged on away from burner hearth, realize spray gun automatic rollback, the function that stops.
