One ends of the two groups of vertical rods 21 are fixedly welded with first fixing blocks 22, and one ends of the two groups of vertical rods 21 near the upper side are fixedly welded with second fixing blocks 23. One sides of the two groups of first fixing blocks 22 are movably connected with main support rods 24, and one sides of the two groups of second fixing blocks 23 are movably provided with auxiliary support rods 25. One sides of the two groups of main support rods 24 and the two groups of auxiliary support rods 25 are movably connected with connecting blocks 26. One ends of the two groups of vertical rods 21 near the lower side are movably installed with hydraulic cylinders 27, and pushing blocks 28 are movably arranged on the upper sides of the two groups of hydraulic cylinders 27. A backing plate 29 is fixedly welded inside the two groups of connecting blocks 26. A bottom plate 210 is fixedly arranged at the lower end of the backing plate 29. A refining furnace body 211 is movably arranged on the upper end of the bottom plate 210. A limiting rod 212 is fixedly welded inside the backing plate 29 near the upper end of the refining furnace body 211.

The height between the bottom plate 210 and the refining furnace body 211 is equal to that of the refining furnace body 211.

[0023] Specifically, first, start the two hydraulic cylinders 27 installed on the lower side of the two vertical rods 21. The expansion rods of the two hydraulic cylinders 27 respectively push the two push blocks 28 connected to them movably, thereby enabling the two push blocks 28 to respectively push one side of the two main support rods 24 to move upward. Then, in cooperation with the two auxiliary support rods 25, the two connecting blocks 26 connected to them movably are pushed together, so that the backrest plate 29 and the bottom plate 210 slowly complete a flip of about 90 degrees. Finally, the upper end of the refining furnace body 211 is clamped by the limiting rod 212, causing the refining furnace body 211 to flip, realizing the automatic dumping of the refining furnace body 211 after the steel liquid refining is completed, facilitating the pouring out of the steel liquid, with strong stability, and the dumping process is relatively simple, saving manpower, so that the dumping effect of the refining furnace is better and it is convenient to meet the use requirements.

[0024] In this embodiment, two main universal wheels 3 are fixedly arranged near the front and rear sides at one end of the chassis 1, a secondary universal wheel 4 is fixedly arranged in the middle of the other side of the chassis 1, a connecting frame 5 is fixedly welded at a position near the upper side of the other side of the chassis 1, and handrails 6 are fixedly welded on the front and rear sides of the connecting frame 5. The two main universal wheels 3 and the secondary universal wheel 4 are at the same horizontal position, and the gap between the two handrails 6 is greater than the width of the backrest plate 29.

[0025] Specifically, by pushing the two handrails 6 and the connecting frame 5, in cooperation with the use of the two main universal wheels 3 and the secondary universal wheel 4, the refining furnace body 211 is flexibly driven to move to the required position, realizing the convenience for workers to use the refining furnace body 211. And the device has a simple structure, is easy to operate, and is relatively small and convenient to move.

[0026] Working principle:

[0027] When in use, first, start the two hydraulic cylinders 27 installed on the lower side of the two vertical rods 21. The expansion rods of the two hydraulic cylinders 27 respectively push the two push blocks 28 connected to them movably, thereby enabling the two push blocks 28 to respectively push one side of the two main support rods 24 to move upward. Then, in cooperation with the two auxiliary support rods 25, the two connecting blocks 26 connected to them movably are pushed together, so that the backrest plate 29 and the bottom plate 210 slowly complete a flip of about 90 degrees. Finally, the upper end of the refining furnace body 211 is clamped by the limiting rod 212, causing the refining furnace body 211 to flip, realizing the automatic dumping of the refining furnace body 211 after the steel liquid refining is completed, facilitating the pouring out of the steel liquid, with strong stability, and the dumping process is relatively simple, saving manpower, so that the dumping effect of the refining furnace is better and it is convenient to meet the use requirements. Additionally, by pushing the two handrails 6 and the connecting frame 5, in cooperation with the use of the two main universal wheels 3 and the secondary universal wheel 4, the refining furnace body 211 is flexibly driven to move to the required position, realizing the convenience for workers to use the refining furnace body 211. And the device has a simple structure, is easy to operate, and is relatively small and convenient to move.
