Technical Field
The utility model relates to the field of slag ladle maintenance devices, in particular to a trunnion dismounting device for a large slag ladle.
Background
The metallurgical slag pot is a container for containing molten steel slag, the trunnion is an important part of the slag pot, and the molten steel slag is frequently lifted during operation, so that the safety performance requirement is extremely high. The slag pot body and the trunnion generally adopt two forms of cold inlay and hot fusion casting. Slag tanks in the form of hot-melt casting trunnions are naturally scrapped along with failure slag tanks of the trunnions, large metallurgical slag tanks are generally in a cold mosaic form, slag tank bodies and the trunnions are manufactured respectively, cold assembling and interference fit are carried out, and the trunnions are replaced when the trunnions fail.
The slag pot contains molten steel slag, and is safe, so that the slag pot is used for a period of time and then is detected according to the standard (the slag pot body is used for 1 time in 2 years and the trunnion is used for 1 time in 1 year), and when the detection does not meet the standard requirement, the parts are repaired or replaced. The trunnion of the large slag ladle is frequently lifted under high load, the surface of the trunnion is worn or the inside of the trunnion is defective, and when the wear amount or the inside defect exceeds the standard, the trunnion needs to be replaced.
The dead trunnion needs to be taken out before the trunnion is replaced, and the trunnion is larger because the trunnion and the trunnion hole are in interference fit, and the trunnion is difficult to be taken out by a common method, so that the trunnion dismounting device which is convenient and quick and does not damage the trunnion hole needs to be designed.
Disclosure of Invention
The utility model aims to solve the problem that the trunnion is difficult to take out in the prior art, and provides a trunnion dismounting device for a large slag pot.
The scheme of the utility model is as follows: the trunnion dismounting device for the large slag pot comprises a portal bracket, wherein the upper end of the portal bracket is provided with a circular arc clamping groove which is matched with an outer end face flange of the trunnion, the lower end of the portal bracket is inserted with a cross rod, two ends of the cross rod are respectively provided with a hydraulic ejector rod, and the middle part of the top end of the portal bracket is provided with a hydraulic ejector rod.
Preferably, two sides of the portal frame are respectively provided with a vertical support plate, the lower ends of the support plates are provided with insertion holes, and the cross bars are detachably arranged in the insertion holes.
Preferably, the cross bar adopts a square billet, and the insertion hole is a rectangular through hole matched with the square billet.
Preferably, the thickness of the portal frame is 40-60cm.
Preferably, the circular arc-shaped clamping groove is arranged in the middle of the door-shaped bracket in the thickness direction.
Compared with the prior art, the utility model has the following beneficial effects: when the slag ladle trunnion is invalid and needs to be replaced, the utility model can conveniently and rapidly disassemble the invalid trunnion, and can avoid damaging the trunnion hole; the device has simple structure and low manufacturing cost; the mode of processing the trunnion on the fixed heavy machine tool is avoided, the processing cost is greatly reduced, and the production cost is reduced.

FIG. 3 is a schematic illustration of a trunnion configuration of a prior art slag ladle;
in the figure: 1. a portal frame; 2. circular arc clamping grooves; 3. square billets; 4. a hydraulic ejector rod; 5. a slag pot; 6. a trunnion; 7. and an outer end face flange.
Detailed Description
As shown in fig. 1-2, the trunnion dismounting device for the large slag ladle comprises a portal frame 1, wherein the upper end of the portal frame 1 is provided with a circular arc clamping groove 2, the circular arc clamping groove 2 is matched with an outer end face flange 7 of a trunnion 6, the lower end of the portal frame 1 is inserted with a cross rod, two ends of the cross rod are respectively provided with a hydraulic ejector rod 4, and the middle part of the top end of the portal frame 1 is provided with the hydraulic ejector rod 4.
Preferably, two sides of the portal frame 1 are respectively provided with a vertical support plate, the lower end of the support plate is provided with a jack, and the cross rod is detachably arranged in the jack.
Preferably, the cross bar adopts a square billet 3, and the insertion hole is a rectangular through hole matched with the square billet 3.
Preferably, in order to improve the rigidity and strength of the portal frame 1, the portal frame 1 is prevented from being deformed by pushing when the hydraulic ejector rod 4 pushes, and the thickness S of the portal frame 1 is 40-60cm.
Preferably, the circular arc-shaped clamping groove 2 is arranged at the middle part of the door-shaped bracket 1 in the thickness direction. The operation method for disassembling the trunnion 6 of the slag pot 5 by adopting the utility model is as follows: firstly, all connecting bolts of the trunnion 6 are disassembled; secondly, the door-shaped bracket 1 is aligned with the outer end face flange 7 of the trunnion 6 from above the trunnion 6 by the circular arc-shaped clamping groove 2, and then the outer end face flange 7 clamping the trunnion 6 is dropped; then, inserting the square billet 3 into the jack, wherein two ends of the square billet 3 are respectively protruded outwards to form a part; finally, a hydraulic ejector rod 4 is respectively arranged in the middle of the upper end of the portal frame 1 and at the two ends of the square billet 3, and the trunnion 6 can be ejected out of the trunnion 6 hole by slowly adjusting the hydraulic ejection force.
The large slag ladle 5 has a large volume and a large weight (up to 60-70 tons), the trunnion 6 is generally close to the ladle opening, the slag ladle 5 is generally inverted for convenient disassembly operation, i.e. the ladle opening is placed downwards, thereby lowering the ground clearance of the trunnion 6, and then the disassembly work of the trunnion 6 is performed by adopting the operation method.
