Description
Technical field
The utility model belongs to technical field of metallurgical equipment, more particularly to there is provided a kind of reversely interdigital steel ladle full lid
Plus take off device.
Background technology
The severe environmental protection pressure in addition of recent year metallurgy industry form, seeks maximally effective energy-saving technological transformation
The most important thing of the project into current iron and steel enterprise.Steel ladle full stroke covering project is undoubtedly the skill that shadow is shown in most effective and vertical rod
One of art transformation project, while also there is increasing steel mill to come into effect.The utility model is exactly to adapt to domestic steel mill
Chips washing system solves the technological difficulties in the steel ladle full stroke covering project implementation, exists for the band that turns over of domestic steel mill ladle
The reverse interdigital uncovery machine that converter side is applicable (i.e. interdigital point points to conticaster).Go for the steel-making of the country more than 70%
Technological transformation of the factory to steel ladle full stroke covering.
The content of the invention
The purpose of this utility model is the provision of a kind of reversely interdigital steel ladle full lid and adds and take off device, solves ladle not
The problem of energy full stroke covering.The action edge of walking of ladle hinge conduction buggy ladle is that the separation of insulation cover and ladle and closure provide dynamic
Power, and abrasion is reduced with coordinating on insulation cover from opening and closing lock hanging plane, it is hinged firm.Leading axle group and stop on insulation cover
It is interdigital safe and reliable that axle group ensures that insulation cover is deposited in, on insulation cover from opening and closing lock hanging ensure ladle upset when insulation cover with
Ladle is hinged stable reliable.
A kind of reversely interdigital steel ladle full stroke covering device, including insulation cover 1, certainly ladle hinge 2, opening and closing lock hanging 11, leading
Axle group 12, braking roll group 13.The one end for being welded in insulation cover 1, leading axle group 12 and braking roll group 13 are fixed from opening and closing lock hanging 11
It is welded on the top of insulation cover 1；Special-shaped axis 21 is arranged on ladle hinge 2, and the integral solder of ladle hinge 2 is on ladle 6；From opening and closing
Lock hanging 11 is hinged with ladle hinge 2, it is ensured that imported and exported from opening and closing lock hanging 11 and special-shaped axis 21 under the horizontal movement state of ladle 6
Relation.Special-shaped axis 21 is fixedly mounted on ladle hinge 2.Ladle 6 it is with cover tumble operation when special-shaped axis 21 serve as insulation cover and enclose
Rotary shaft when rotating around it, anti-dropout locking device is served as from opening and closing lock hanging 11.Leading axle group 12 and braking roll group 13 and fork
Refer to 3 to be in rolling contact, insulation cover leads a liter falling relation under the horizontal movement state of ladle 6.
Insulation cover 1 is that two layers above and below steel construction piece, its body point, upper strata is frame structure layer, and lower floor is that steel plate is surrounded
Filling fire resisting material in housing, housing, in order to keep the fastness and stability of resistance to material, filling housing side and top surface arrange anchor
1-2 fabrication hole is opened up on firmware, the big face of insulation cover 1, for thermometric sampling plus stuffing sand and burning air brick passage etc.；Protect
The resistance to material gross thickness of temperature lid is 140mm-160mm, and it is full with the resistance to material knotting of castable again that hull plate first lays aeroge station heat insulation layer
Sufficient adiabatic heat-insulation function and alleviation thermal expansion cause the influence to housing；Total high between 450~900mm, the satisfaction of insulation cover 1
Technique passes through smelting station on ladle with cover, and (LF, RH, CAS station of such as steel mill, each tapping hole operation of iron-smelter are flat
Platform) requirement.
The angled arrangement of the flat cross section of special-shaped axis 21 on ladle hinge 2, the same angle of inverted U notch from opening and closing lock hanging 11
Degree arrangement, downwards, two legs have the discrepancy in elevation to oral area, with respect to the side of insulation cover 1, and the leg of inner side will lean out 80mm-160mm down.
Include the eccentric lock pin 32 of abnormity, gyroaxis 31, limited block 33 and with inverted U mouthful from opening and closing lock hanging 11；Gyroaxis 31
It is welded on limited block 33 on lock hanging substrate 30, abnormity bias lock pin 32 is arranged in lock hanging substrate 30, is coordinated with gyroaxis 31
Rotated around gyroaxis 31.Special-shaped bias lock pin 32 rotates rotation to abnormity bias lock pin 32 at 20 ° -22 ° and limit around gyroaxis 31
Position block 33 is contacted for limiting rotation angle it is avoided that jam；When insulation cover 1 is more than 45 ° with the upset of ladle 6 with horizontal sextant angle
Special-shaped bias lock pin 32 is rotated inverted U-shaped mouth locking around gyroaxis 31, prevents that insulation cover 1 takes off with ladle hinge 2 when ladle 6 from overturning
Open.When insulation cover is less than 30 ° with ladle upset with horizontal sextant angle, the eccentric lock pin 32 of abnormity rotates return, lock hanging around gyroaxis 32
Inverted U-shaped mouth open mode on substrate 30, it is ensured that ladle hinge special-shaped axis import and export cooperation reversely interdigital uncovery machine take off lid/
Capping.This covering device knot is simply difficult jam, more effectively ensure that the security reliability of slew gear.
Ladle hinge 2 includes rocker bar bearing 20, special-shaped axis 21, fixed plate 22, axle end baffle plate 23 and bolt.Special-shaped axis 21,
Fixed plate 22 and axle end baffle plate 23 are connected with being arranged on rocker bar bearing 20, and integral solder is on ladle 6.Fixed plate 22 half
Circle perforate shares bolt with the convex dosing of the semi-circle plane of special-shaped axis 21 and ensures that special-shaped axis 21 will not rotate on rocker bar bearing 20；
Special-shaped axis 21 and fixed plate 22 are connected with bolt with axle end baffle plate 23 respectively, it is ensured that special-shaped axis 21 will not left and right play.
Ladle hinge 2 coordinates with insulation cover 1, coordinates reverse interdigital uncovery machine to take off lid/capping action.Special-shaped axis 21 it is flat
Plane is fitted even closer with from the inverted U-shaped face of opening and closing lock hanging 11, it is to avoid is slipped mistake power when taking off lid too early and is caused lid, top surface circular arc
Shape is freely excessive to mistake mechanical compliance to power to Gai Shicong is taken off, and makes to take off lid process and more smoothes out.
Braking roll group 13 includes axle group bearing 40, rotary shaft 41, fixing axle 42, self-lubricating bearing 43 and back-up ring 44.From profit
Plain besring 43 and fixing axle 42 are welded on axle group bearing 40；Rotary shaft 41 is arranged in self-lubricating bearing 43, and back-up ring 44 uses spiral shell
Bolt be arranged on rotary shaft 41 two ends, prevent rotary shaft 41 rotate when or so play.Insulation cover edge is reversely interdigital upward when taking off lid
Rotary shaft on walking, insulation cover in leading axle group 12 and braking roll group 13 is in rolling contact reduction resistance with reversely interdigital.Take off lid
The fixing axle 42 and interdigital safety groove CONTACT WITH FRICTION in braking roll group 13 in a flash are completed, because the non-rotatable frictional force of fixing axle adds
Greatly, firm the resting on of insulation cover is made to increase safety factor above interdigital.
The utility model has the advantage of it is fast reliable that lid job safety is taken off in capping, will thoroughly solve steel ladle full stroke covering
The problems such as operating habit needs to change when the rhythm of production that user worries in technique extension process is impacted and topples over residual steel residue,
All-round popularization to steel ladle full stroke covering technique will produce actively impact.
