Description

Technical Field

[0001] The utility model relates to the field of metallurgical materials, in particular to a novel oxygen lance base. Background Art

[0002] The oxygen lance blows high-pressure and high-purity oxygen at supersonic speed into the top of the molten metal pool in the converter. When the oxygen lance is used in the furnace, it is sometimes necessary to deflect a certain angle. The existing oxygen lance cannot do this, so the oxygen supply position is usually adjusted by moving the entire oxygen lance. Moving the entire oxygen lance is cumbersome, time-consuming and labor-intensive, which brings great inconvenience to production. Utility Model Content

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses a novel oxygen gun base, comprising two groups of left and right fastening components, wherein the fastening components comprise two groups of arc-shaped seat bodies and two arc-shaped plates, one end of the arc-shaped plate is hinged at one end of the seat body, the other ends of the two arc-shaped plates are connected, and the two seat bodies are connected by a connecting rod; mounting holes are provided on the seat body and the arc-shaped plate, an internal threaded sleeve is fixed in the mounting hole, an adjusting screw is threadedly connected in the internal threaded sleeve, a rotating handle is connected on one end of the adjusting screw placed outside, a spherical top block is connected on the other end of the adjusting screw on the left seat body and the arc-shaped plate, and a top plate is universally connected on the other end of the adjusting screw on the right seat body and the arc-shaped plate.

[0006] Furthermore, a fixing plate is connected to one end of the arc-shaped plate away from the base body, a through hole is formed on the fixing plate, and the two fixing plates are fixed to each other after being inserted into the through hole by fastening bolts.

[0007] Furthermore, the arc-shaped plate is hinged on the seat body through pins, and the front and rear groups of the pins are connected.

[0008] Furthermore, the angle between two adjacent adjusting screws is 90°.

[0009] Compared with the prior art, the beneficial technical effects of the utility model are:

[0010] The utility model has a simple structure and is convenient for adjustment. When the oxygen gun needs to be deflected in each direction, the reverse adjusting screw on the left fastening component is adjusted outward, and the other adjusting screw opposite to it is adjusted inward, and the adjusting screw on the right side is kept stationary, and only the top plate is deflected in coordination, thereby realizing the angle adjustment of the overall oxygen gun and greatly improving the production efficiency.

[0016] like Figure 1-3 As shown, a novel oxygen gun base includes two left and right groups of fastening components, wherein the fastening components include an arc-shaped seat body 1 and two arc-shaped plates 2, wherein the seat body 1 is connected to the furnace wall, and one end of the arc-shaped plate 2 is hinged to one end of the seat body 1 through a pin 11, and a fixing plate 9 is connected to the end of the arc-shaped plate 2 away from the seat body 1, and a through hole is opened on the fixing plate 9, and the two fixing plates 9 are fixed to each other after the fastening bolts 10 are inserted into the through holes.

[0017] The two seats 1 on the two groups of fastening components are connected by a connecting rod 3 to ensure the integrity of the device, and the pins 11 on the front and rear groups of fastening components are connected.

[0018] The seat body 1 and the curved plate 2 are both provided with mounting holes, and an internal threaded sleeve 4 is fixed in the mounting hole, and an adjusting screw 5 is threadedly connected in the internal threaded sleeve 4, and the angle between two adjacent adjusting screws 5 is 90°. A rotating handle 6 is connected to one end of the adjusting screw 5 placed outside, and a spherical top block 7 is connected to the other end of the adjusting screw 5 on the seat body 1 and the curved plate 2 on the left side, and a top plate 8 is universally connected to the other end of the adjusting screw 5 on the seat body 1 and the curved plate 2 on the right side.

[0019] The action process of the utility model is as follows:

[0020] When in use, unscrew the fastening bolts 10 to open the two arc plates 2, place the bottom of the oxygen gun inside the seat body 1 and the two arc plates 2, then fix the arc plates 2 with the fastening bolts 10, and then turn each rotating handle 6 to fix the bottom of the oxygen gun. When the angle needs to be adjusted, find the corresponding rotating handle 6 on the left, turn the rotating handle 6 to adjust the angle of the left end of the bottom of the oxygen gun, and then the top plate 8 on the right will rotate with the angle because it is a universal connection, thereby achieving the purpose of adjusting the angle.
