The hot quick replacement device for ladle supper nozzle and external porous brick core has flexible and safe operation and improves the work efficiency.
Description
Technical field
The utility model relates to the online hot repair Aided Machine of a kind of ladle in the steelmaking equipment field, mainly is to be used for ladle upper nozzle and the hot quick replacement device of externally installed permeable brick core.
Background technology
In the prior art, the method that steel plant change ladle upper nozzle mainly contains two kinds: big ladle adopts the replacing of rolling off the production line, medium and small ladle is to adopt online pneumatic pick operation, change the mode that the externally installed permeable brick core mainly adopts artificial bump, there is following problem in this kind operation: the one, change suitable slow of ladle upper nozzle and externally installed permeable brick core speed, cause the anxiety of rhythm of production through regular meeting, this has brought a lot of inconvenience for three permanent stable operations of conticaster constant level, permanent pulling rate, stationary temperature; The 2nd, replacing speed causes the cylinder-packing temperature drop excessive slowly easily, reduces ladle bag age; The 3rd, this kind operation worker labour intensity is quite big, and safety coefficient is low.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, operating aspect, flexibly, safety, high efficiency, the device that replaces with the mouth of a river and externally installed permeable brick fast that can singlely operate.
The purpose of this utility model is come specific implementation by following scheme.This device constitutes by supporting tiling arrangement and power draw-off gear, its A-frame that supports tiling arrangement is connected with fixed support by connection bearing, fixed support is fixedly installed on the ladle hot repair bit platform, and A-frame can be through connection bearing with respect to the fixed support axial rotation; On the cross bar of A-frame, have hanger; The drawing joint of power draw-off gear is hinged through an end of bearing pin and drawing bar, and the other end of drawing bar is connected with the drawing hydraulic cylinder, is installed with the cylinder tight sleeve on the drawing hydraulic cylinder; The drawing hydraulic cylinder is installed on the hanger through a lowering or hoisting gear.
During use, the drawing joint is connected to an end of drawing bar through bearing pin, and the ladle parts that drawing joint locking need be extracted, the other end of drawing bar is linked to each other with the drawing hydraulic cylinder, adjusting makes the cylinder tight sleeve hold out against the ladle parts, starts the ladle parts that hydraulic cylinder extracts needs then and pulls out from ladle.Rotation is at last supported tiling arrangement equipment is left dress bag district.
The utility model flexible operation, convenient, safety can a people be finished all operations, has improved operating efficiency greatly, can avoid long working under hot environment.And complete equipment is simple in structure, and is with low cost.

The specific embodiment
In conjunction with the accompanying drawings the utility model is described further by explanation.This device constitutes by supporting tiling arrangement and power draw-off gear, the A-frame (3) that supports tiling arrangement is connected with fixed support (1) by connection bearing (2), fixed support (1) is fixedly mounted on the ladle hot repair bit platform, A-frame (3) can pass through connection bearing (2) with respect to fixed support (1) axial rotation, has hanger (4) on the cross bar of A-frame (3); The drawing joint (5) of power draw-off gear is hinged through an end of bearing pin and drawing bar (6), and the other end of drawing bar (6) is connected with drawing hydraulic cylinder (8), is fixed with cylinder tight sleeve (7) on drawing hydraulic cylinder (8); Drawing hydraulic cylinder (8) is installed on the hanger (4) through a lowering or hoisting gear.
According to the article difference of changing, drawing joint (5) can be made different version.With reference to accompanying drawing 2,3,4, when being used to change ladle upper nozzle, drawing joint (5) can be made boss structure, and can rotate freely 180 degree around the drawing bar, at this moment, after drawing joint (5) connects with drawing bar (6), drawing joint (5) revolved turn 90 degrees, its main body is parallel with drawing bar (6), is convenient to fill in the ladle upper nozzle, jiggles several following simultaneously, under the self gravitation of drawing joint (5), main body becomes plumbness with drawing bar (6), the drawing joint will with the ladle upper nozzle auto lock, be convenient to the drawing ladle upper nozzle like this.
With reference to accompanying drawing 7,8,9, when being used to change the externally installed permeable brick core, drawing joint (5) can be made the chuck mode structure, links to each other with air brick Argon round steel pipe by it, clamps pipe it is extracted.
Drawing hydraulic cylinder (8) is installed in the lowering or hoisting gear on the hanger (4), can be hoist engine, also hydraulicefficiency elevation structure or jack mechanism.
For the sake of security, an insurance steel cable is installed between hanger (4) and power draw-off gear, the security insurance effect is provided for so whole device.
