Description
Technical Field
The utility model relates to a do not have first hot rolling belted steel work roller bearing dismouting handling device entirely belongs to metallurgical industry and does not have first hot rolling belted steel work roller bearing dismouting technical field entirely.
Background
The continuous casting and rolling technique (ESP) for endless strip steel is a new technology for producing plate and band in recent years, and the full endless hot-rolling working roll bearing is used for supporting the roll, and is characterized by large unit pressure, large difference in running speed, and severe working environment. Because ESP thin specification proportion is large, rolling load is higher, the roller is continuously rolled after being arranged on the machine, and the requirement on the roller bearing is higher. Therefore, the bearing needs to be frequently disassembled and assembled and maintained, and the smooth production is ensured. The rough rolling mill and the finish rolling mill both have working roll bearings with different sizes, and because the working roll bearings do not have standard hoisting tools, the former method is to use two iron sheets to hook the retainer for hoisting, because each bearing is divided into two parts, the hoisting needs to be carried out twice, which is unsafe, and the bearings are easy to damage, thereby wasting time and labor.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a no first hot rolling belted steel work roll bearing dismouting handling device, can quick assembly disassembly work roll bearing, effectively reduce the bearing damage, the problem that exists among the solution background art is solved in the emergence of prevention incident.
The technical scheme of the utility model is that:
a full-endless hot-rolled strip steel working roller bearing dismounting and carrying device comprises a lifting mandrel, slide ways, sleeves, supporting connecting rods, lifting hook stand columns, supporting claws, positioning bolts and lifting rings, wherein the three slide ways are respectively welded on the sleeves, the three slide ways are positioned on the same plane, the included angle between every two adjacent slide ways is 120 degrees, each slide way is connected with one lifting hook stand column in a sliding mode, and the lower end of each lifting hook stand column is provided with the supporting claw matched with a working roller bearing; the lifting mandrel penetrates through the sleeve, a positioning bolt is arranged between the lifting mandrel and the sleeve, a hanging ring is arranged at the upper end of the lifting mandrel, and the lower end of the lifting mandrel is connected with each lifting hook stand column through corresponding supporting connecting rods.
And the two ends of the supporting connecting rod are respectively connected with the lifting core shaft and the lifting hook upright post through connecting bolts.
And the lifting mandrel is provided with a positioning hole matched with the positioning bolt.
The utility model has the advantages that: the working roller bearing can be quickly disassembled and assembled, the damage of the working bearing is effectively reduced, the working efficiency is improved, the labor intensity of workers is reduced, and safety accidents are prevented.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a slide arrangement;
in the figure: lifting core shaft 1, slide 2, sleeve 3, support connecting rod 4, lifting hook stand 5, round pin axle 6, hold in the palm claw 7, positioning bolt 8, rings 9.
Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached drawings 1-2, the dismounting and carrying device for the full-endless hot-rolled strip steel working roll bearing comprises a lifting mandrel 1, slide ways 2, a sleeve 3, a supporting connecting rod 4, lifting hook upright posts 5, supporting claws 7, a positioning bolt 8 and a lifting ring 9, wherein the three slide ways 2 are respectively welded on the sleeve 3, the three slide ways 2 are on the same plane, the included angle between every two adjacent slide ways 2 is 120 degrees, each slide way 2 is connected with one lifting hook upright post 5 in a sliding manner, and the lower end of each lifting hook upright post 5 is provided with the supporting claw 7 matched with the working roll bearing; the lifting mandrel 1 penetrates through the sleeve 3, a positioning bolt 8 is arranged between the lifting mandrel 1 and the sleeve 3, a hanging ring 9 is arranged at the upper end of the lifting mandrel 1, and the lower end of the lifting mandrel 1 is connected with each lifting hook upright post 5 through a corresponding supporting connecting rod 4.
In the embodiment, the lifting mandrel 1 is provided with a lifting ring 9 at the uppermost edge, and a lifting belt penetrates through the lifting mandrel during working; the middle part of the lifting mandrel 1 penetrates through the sleeve 3; the lifting mandrel 1 is provided with a positioning hole which is matched with the positioning bolt 8 for use; the bottom of the lifting mandrel 1 is connected with a lifting hook upright post 5 through a supporting connecting rod 4.
Three slide 2 weld respectively on sleeve 3, and its respective contained angle of three slide 2 is 120 evenly distributed in a plane, as shown in fig. 2, installs positioning bolt 8 on the sleeve 3 for the position of location lift dabber 1.
The upper parts of the three lifting hook upright columns 5 are embedded into the three slideways 2, the middle parts of the three lifting hook upright columns are connected with the lifting hook upright columns 5 through the supporting connecting rods 4, and the lifting hook upright columns 5, the supporting connecting rods 4 and the lifting mandrel 1 are connected through the connecting bolts 6. The bottom of the lifting hook upright post 5 is provided with three supporting claws 7 which are used for supporting the bottom of the working roller bearing to hoist during working.
The supporting connecting rod 4 can adjust the position of the lifting hook upright post 5, and can simultaneously meet the hoisting requirements of all working roller bearings with different sizes of a rolling line.
The specific use method is as follows:
before the working roll bearing is hung out, the positioning bolt 8 is screwed into the positioning hole, the position of the lifting mandrel 1 is ensured to be in a fixed state, and the lifting hook upright post 5 is ensured to be in a contraction state. Then hoisting the device by using a hoisting belt, vertically placing the device into the inner ring of the bearing of the working roll, placing the device at the bottom and then loosening the positioning bolt 8; after the manual work confirms that the device is lifted in place, the lifting mandrel 1 is in a movable state at the moment, in the lifting process, the lifting hook upright post 5 is slowly expanded, and after the lifting hook upright post 5 contacts the inner ring of the bearing, the supporting claw 7 of the lifting hook upright post 5 can drag the lower edge of the bearing to continuously lift, so that the bearing is integrally lifted out once.
The process of mounting the bearing is the same as the process of lifting out.
