Abstract
The utility model relates to a 120-tonnage converter non-transmission-side trunnion lengthening device which comprises a reducing trunnion body, wherein one end of the trunnion body has a straight angle, and the other end of the trunnion body has a chamfer angle. A projecting flange is arranged on the trunnion body and provided with a screw hole. The 120-tonnage converter non-transmission-side trunnion lengthening device is simple in structure, small in volume, and low in cost, can be switched in a non-transmission-side trunnion, the 120-tonnage converter non-transmission-side trunnion lengthening device is connected with the non-transmission-side trunnion to lengthen the non-transmission-side trunnion and provide a jacking point for jacking, and can bear the overall weight of a converter in one-side jacking to achieve the safety and fastness purposes.
Description
Technical field
The utility model relates to converter installation industrial technology field, relates in particular to 120 tons of converter non-drive side trunnion extending devices.
Background technology
Converter is the major equipment of iron and steel enterprise's steel-making, occupy an important position in whole Iron and Steel Production, the revolving furnace body weight of equipment is large, and the furnace axis bearing has been born all wt of converter, because the trunnion of converter bearing does not belong to consumable accessory, after producing for a long time, general converter just occurs damaging.The ball socketed bearing of iron and steel enterprise's replacing at present is all to make a lifting-up support at furnace bottom converter to be carried out the ball socketed bearing replacing after whole jack-up, and the replacing of ball socketed bearing is the meticulous work in maintenance, need to take into full account the intensity calculating of temporary support, can not carry out by rule of thumb.The installation of temporary support will take full advantage of on-the-spot condition and install.This method weak point is long construction period, and the construction task amount is large, difficulty large, cost is higher.
Due to basic without load-bearing under 120 tons of converter non-drive side trunnions, be a tubular shaft and a load-bearing basis and non-back side gudgeon are arranged tiltedly, therefore when changing, ball socketed bearing easily caves in.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, loading and unloading 120 tons of converter non-drive side trunnion extending devices efficiently.
For addressing the above problem, 120 tons of converter non-drive side trunnion extending devices described in the utility model is characterized in that: it comprises that an end is that the straight angle, the other end are the spindle body that is reducing of chamfering; Described spindle body is provided with raised flanges, and this raised flanges is provided with screw.
The port of described raised flanges one side is that the diameter of the described spindle body of chamfering is the diameter of the described spindle body of the straight angle less than the port of described raised flanges opposite side.
Described raised flanges is located at 1/4 ~ 1/3 total strong point of described spindle body apart from chamfered end.
The utility model compared with prior art has the following advantages:
1, the utility model can be cut in non-back side gudgeon, with the length that has lengthened gudgeon after non-back side gudgeon is connected, for jacking provides a Jacking point, and can bear the weight of converter integral body when single-side jacking, therefore, improved safety performance, the appearance of the phenomenon of having avoided caving in.
2, the utility model has substituted jacking apparatus under old-fashioned stove fully, has reduced tooling cost and settling time, has shortened simultaneously the whole duration.
3, the utility model converter integral body when the jacking 1 ° of replacing that just can complete non-back side ball socketed bearing of only tilting, and can guarantee that converter integral body is not shifted, not only convenient but also quick.
4, the utility model is simple in structure, volume is little, with low cost, can be used in replacing with of 120 tons of converter non-drive side trunnion bearings.
Description of drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is specifically implemented schematic diagram.
In figure: the jacking apparatus 4 of 1-spindle body, 2-screw, 3-screw block cooperation U type support-6-120 tons of 5-120 tons of converter bodies of non-back side bearing bag converter trunnion ring 7-back side bearing bag, 8-back side bearing package base, 9-non-back side bearing package base 10-non-back side gudgeon.
Embodiment
As shown in Figure 1,120 tons of converter non-drive side trunnion extending devices, it comprises that an end is that the straight angle, the other end are the spindle body 1 that is reducing of chamfering.Spindle body 1 is provided with raised flanges, and this raised flanges is provided with screw 2.
Wherein: the port of raised flanges one side is that the diameter of stating spindle body 1 of chamfering is the diameter of the spindle body 1 of the straight angle less than the port of raised flanges opposite side.
Raised flanges is located at 1/4 ~ 1/3 total strong point of spindle body 1 apart from chamfered end.
During use, ⑴ removes the non-back side swivel joint of 120 tons of converter bodies 5; ⑵ throw off the torsion bar that fascinates of 120 tons of converter bodies 5; ⑶ remove non-back side bearing bag 4 and the back side bearing bag 7 of 120 tons of converter body 5 both sides; ⑷ pack spindle body 1 in non-back side gudgeon 10, ring flange is connected (referring to Fig. 2 with the bolt hole of former installation swivel joint by screw 2 with bolt, in figure 6 is 120 tons of converter trunnion rings, and 8 is back side bearing package base, and 9 is non-back side bearing package base.); ⑸ install the jacking apparatus 3 that screw block coordinates U type support below non-back side gudgeon 10, then with the non-back side gudgeon 10 of screw block group jacking, just can carry out the bearing replacing of non-back side gudgeon 10 after rising 180mm.
Claims (3)
