[0002] An electroslag remelting furnace is a device that uses the heat energy generated by electric current passing through high-resistance molten slag to remelt metal. Electroslag remelting is generally carried out under atmospheric pressure. If needed, a vacuum unit can also be configured for vacuum refining.

[0003] When the radar level gauge for measuring the liquid level of the slag electric furnace is working, it is necessary to align the measuring point of the radar level gauge with the measuring port above the electroslag remelting furnace. However, when the radar level gauge is inspected and repaired, the temperature at the measuring port of the slag electric furnace is relatively high, and it is dangerous for the staff to go forward for inspection and repair. In addition, the current radar level gauge is fixed by the flange on the radar level gauge during installation, but the maintenance frequency of the radar level gauge is relatively high. When it needs to be disassembled for inspection and repair, the above-mentioned fixed installation operation will cause great trouble to the staff, affecting the staff's operation.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Figure 1-4 As shown, the utility model provides a slag electric furnace liquid level measuring device, including a bracket 1, a circular bolt hole 43 is opened at the bottom of the bracket 1, and the bolt hole 43 can be conveniently fixed to the bracket 1 on the slag electric furnace tank 5. The bottom of the bracket 1 is fixedly mounted with the upper surface of the slag electric furnace tank 5, and the top of the bracket 1 is fixed with a bottom plate 11, a rotating column 12 is rotatably provided on the bottom plate 11, and a first movable plate 13 is fixedly provided on the rotating column 12. A second movable plate 14 is movably inserted on the first movable plate 13, and an adjustment plate 13 is provided between the first movable plate 13 and the second movable plate 14. Component, the second movable plate 14 is fixed with a mounting block 141 at one end away from the rotating column 12, a radar level gauge 15 is installed on the mounting block 141, a mounting plate 16 is installed on the radar level gauge 15, and two symmetrically arranged clamping blocks 17 are fixed on the lower surface of the mounting plate 16, a clamping groove 18 for the clamping block 17 is provided on the mounting block 141, a slot 19 is provided through the clamping block 17, a plug rod 2 is inserted into the mounting block 141 near the slot 19, and a connecting plate 21 is fixed to the two plug rods 2 at one end outside the mounting block 141, and a screw rod 22 is threadedly inserted into the connecting plate 21.

[0019] A first gear 4 is fixedly provided at the bottom of the rotating column 12, and a second gear 41 is rotatably provided on the base plate 11 and is meshed with the first gear 4. A drive motor 42 is fixedly installed on the base plate 11, and the output end of the drive motor 42 is coaxially fixed on the second gear 41. The drive motor 42 can directly drive the second gear 41 to drive the first gear 4 to rotate, which is convenient for the staff to operate.

[0020] A U-shaped fixing bracket 23 is fixed to the outer wall of the mounting plate 16 near the screw rod 22. The end of the screw rod 22 away from the mounting block 141 passes through the fixing bracket 23 and is fixed with a rotating wheel 24. The rotating wheel 24 can facilitate the staff to directly drive the screw rod 22 to rotate, thereby improving the convenience of operation.

[0021] The adjustment component includes a positioning groove 3, which is provided on the side wall of the first movable plate 13. The positioning groove 3 is provided in multiple numbers and is evenly spaced and arranged on the first movable plate 13. A rotating rod 31 is provided at one end of the second movable plate 14 close to the bottom plate 11, and a swing plate 32 is fixed on the rotating rod 31. The top of the swing plate 32 is arranged in an arc shape, and a push block 33 is fixed at one end of the swing plate 32 away from the positioning groove 3. When the swing plate 32 is squeezed by the push block 33, the top of the swing plate 32 can be separated from the positioning groove 3, thereby canceling the stop between the first movable plate 13 and the second movable plate 14, so that the first movable plate 13 and the second movable plate 14 can be adjusted. 4, which makes it more convenient to adjust the radar level gauge 15; a spring 35 is fixed to one end of the second movable plate 14 close to the swing plate 32, and the end of the spring 35 away from the inner wall of the second movable plate 14 is fixed to the swing plate 32. The provided spring 35 can make the swing plate 32 not be squeezed by the push block 33, so that the end of the swing plate 32 can always be stuck in the positioning groove 3, thereby stopping the second movable plate 14; the end of the push block 33 away from the swing plate 32 passes through the second movable plate 14 and is fixed with a squeezing plate 34. The provided squeezing plate 34 can facilitate the staff to squeeze the swing plate 32 conveniently to work, and control the end of the swing plate 32 to leave the positioning groove 3.

[0022] Working principle: When in use, the staff can start the driving motor 42, and the output end of the driving motor 42 can directly drive the first gear 4 to rotate through the second gear 41. At this time, the first gear 4 will drive the fixed rotating column 12 to rotate. At this time, the first movable plate 13 fixed on the rotating column 12 drives the position of the radar level gauge 15 to move through the second movable plate 14, so that the radar level gauge 15 is away from directly above the liquid level measuring port of the slag electric furnace. At this time, the staff can directly inspect the radar level gauge 15 away from the liquid level measuring port of the slag electric furnace. At the same time, when installing the radar level gauge 15, the staff can first install the bracket 1 at the end away from the liquid level measuring port of the slag electric furnace, squeeze the end of the swing plate 32 out of the positioning groove 3 through the squeezing plate 34, and then directly pull the second movable plate 14 to move, so that the radar level gauge 15 moves to above the liquid level measuring port of the slag electric furnace. At this time, the installation does not need to be installed close to the liquid level measuring port of the slag electric furnace, which increases the safety of the staff when installing the radar level gauge 15 on the slag electric furnace tank 5;

[0023] At the same time, when the staff needs to disassemble the radar level gauge 15 for maintenance, the staff can directly drive the screw rod 22 to rotate through the turntable 24. At this time, the connecting plate 21 with a threaded arrangement on the screw rod 22 will drive the plug rod 2 set at both ends to gradually disengage from the mounting block 141, and the plug rod 2 will disengage from the slot 18 on the block 17, canceling the fixation of the mounting plate 16 on the radar level gauge 15. At this time, the staff can directly pull out the radar level gauge 15 to complete the disassembly. During subsequent installation, the block 17 on the radar level gauge 15 will be aligned with the slot 18 on the mounting block 141 and inserted. The screw rod 22 can be rotated in reverse to complete the fixed installation, which greatly improves the installation and disassembly of the radar level gauge 15 and facilitates subsequent operations by the staff.

[0024] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
