Abstract
The utility model discloses a device for dismounting a tuyere middle sleeve of a blast furnace. The device comprises a support, draw hooks and a support rod, wherein the two draw hooks are symmetrically and fixedly welded on the two sides of the round hole of the support and form the shape of an inverted splay, and the support rod passes through the interior of a pipe sleeve on the support. The draw hooks are pushed outwards by hammering the support rod and hook the tuyere middle sleeve, and the middle sleeve is pulled upward through a lifting jack, as a result, the tuyere middle sleeve is taken out. The device has a light weight and a simple structure, is convenient to operate, and is particularly suitable for being used in production of small blast furnaces in iron-making industry.
Description
Technical field
The utility model belongs to the ironmaking utility appliance, relates in particular to a kind of device that blast-furnace tuyere overlaps that is used for dismantling.
Background technology
In the medium and small blast furnace of iron industry, cover in three of the upper, middle and lower is arranged.Because need blowing in the constantly past stove, middle cover damages especially easily, adds factors such as high temperature, the middle cover after the damage is prone to take place the mill leakage, thereby causes leaking.Therefore, middle cover needs often to change.When cover is changed in the blast-furnace tuyere at present, adopt the frame hammer that cover in the air port is unloaded usually.This instrument is the hook of round steel one end weldering by diameter 40 ㎜, and on round steel, overlaps a sliding hammer, in the both sides of sliding hammer two ropes of a little ring bolt is arranged respectively; At firm drag plate of the other end of round steel weldering, an end that tool rack is had a hook during cover in the wind outlet stretches in the air port in the cover, hooks the interior top of overlapping in the air port; The people stands in the both sides in air port, and the sliding hammer of pulling rope whipping hits the drag plate through sliding the hammering; Form a kind of outside strength in air port that spurs, cover in the air port is unloaded.
This mode efficient is low, and labor strength is big, also has potential safety hazard simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of being used for and dismantles the device that blast-furnace tuyere overlaps, and the utility model is in light weight, and is simple in structure, easy to operate, is particularly suitable in the ironmaking medium and small blast furnace is produced, using.
Technical scheme: the utility model comprises a support, drag hook and strut.
Said support is rectangle, and the middle has a circular hole, hole internal fixing one circular pipe box; Said drag hook is a straight-bar, has two, the head bending, and two drag hook afterbody symmetries are weldingly fixed on the circular hole both sides on the support, are herringbone, and its bending part is outwardly; Said strut is a T-shaped, and the strut head is welded with fagging, and in the pipe box of strut on the support, fagging is between two drag hooks.
Be to guarantee the intensity of support and strut, be welded with gusset at support and pipe box and strut and fagging junction.
Beneficial effect: the utility model is in light weight, and is simple in structure, easy to operate, is particularly suitable in the ironmaking medium and small blast furnace is produced, using.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Specify below in conjunction with accompanying drawing.
As shown in the figure:
In the middle of a rectangular support frame 1, have a circular hole, hole internal fixing one circular pipe box 3; The both sides of pipe box 3 on support 1, two drag hook 2, two drag hooks 2 of symmetry welding are herringbone, the outside bending of afterbody; One strut 4 is arranged in the pipe box, and the strut head is welded with fagging 6.
Be to guarantee the intensity of support and strut, be welded with gusset 5 and 7 respectively at support and pipe box and strut and fagging.
During work, below the both wings of rectangular support frame 1, place two screw block, downward hammering strut 4, strut 4 terminal faggings 6 outwards strut drag hook 2, hook in the air port and overlap, and upwards spur in the air port through screw block and overlap, thereby realize taking out the purpose of overlapping in the air port.
Claims (1)
1. one kind is used for dismantling the device that blast-furnace tuyere overlaps, and comprises a support, drag hook and strut, and it is characterized in that: said support is rectangle, and the middle has a circular hole, hole internal fixing one circular pipe box; Said drag hook is a straight-bar, has two, the head bending, and two drag hook afterbody symmetries are weldingly fixed on the circular hole both sides on the support, are herringbone, and its bending part is outwardly; Said strut is a T-shaped, and the strut head is welded with fagging, and in the pipe box of strut on the support, fagging is between two drag hooks.
