Description

Technical Field

[0001] The utility model belongs to the technical field of steel smelting equipment, and in particular relates to a meshing-type molten steel sampling device. Background Art

[0002] At present, the chemical composition, gas content and inclusion composition of molten steel are important references for process control in the steelmaking process. Therefore, extracting a certain amount of molten steel from the ladle as a sample has become an important process in the steel production process. The usual molten steel sampler includes a suspension rod, a vertical rod and a sampling cup. The sampling cup is fixed at one end of the vertical rod, and the other end of the vertical rod is flexibly connected to the suspension rod. When in use, the operator grabs the suspension rod to immerse the sampling cup in the molten steel, and then takes out the sampling cup filled with molten steel. After the molten steel solidifies, the corresponding physical and chemical properties are tested so that the process parameters can be adjusted in time. Since the sampler is far away from the ladle opening, the suspension rod usually has a certain inclination angle. Under the action of the gravity torque of the sampling cup, the slender suspension rod will bend. In this way, the sampling cup may bump into the lining material of the ladle, and the existing technical device cannot achieve the purpose of vacuum sampling.

[0055] Then, the eight eighth bosses 702 of the eight linear bearings 7 are inserted into the four eleventh through holes 803 of the working block 8, and the thirty-two ninth through holes 703 of the eight linear bearings 7 are aligned with the sixteen fourth screw holes 804 of the working block 8, and then the thirty-two screws 4 are passed through the thirty-two ninth through holes 703 and screwed into the sixteen fourth screw holes 804, so that the eight linear bearings 7 and the working block 8 can be assembled by the thirty-two screws 4;

[0056] Then, the four ninth bosses 1102 of the fifth bracket 11 are inserted into the eight tenth through holes 704 of the eight linear bearings 7, and then the four fifth bosses 502 of the third bracket 5 are arranged outside the front and rear end surfaces of the working block 8, and the four sixth through holes 504 of the third bracket 5 and the four second screw holes 801 of the working block 8 are aligned, and then the four screws 4 are passed through the four sixth through holes 504 and screwed into the four second screw holes 801, so that the third bracket 5 and the working block 8 can be assembled by the four screws 4;

[0057] Then, the four locking sections 1001 of the four rotating shafts 10 are inserted into the eight twelfth through holes 902 of the eight gears 9, and then one hinge 14 is installed in each of the sixteen thirteenth through holes 1003 of the four rotating shafts 10. In this way, the four rotating shafts 10 and the eight gears 9 can be assembled.

[0058] Then, one rolling bearing 12 is installed in each of the eight first grooves 105 of the four first brackets 1, and then the four first brackets 1 are arranged opposite to each other in pairs, and then the eight bearing sections 1002 of the four rotating shafts 10 are inserted into the eight rolling bearings 12, so that the four first brackets 1, the eight rolling bearings 12 and the four rotating shafts 10 can be assembled;

[0059] Then, the four through slots 107 of the four first brackets 1 are sleeved outside the four seventh bosses 603 of the fourth bracket 6, and the thirty-two first through holes 104 of the four first brackets 1 are aligned with the sixteen first screw holes 605 of the fourth bracket 6, and then the thirty-two screws 4 are passed through the thirty-two first through holes 104 and screwed into the sixteen first screw holes 605, so that the four first brackets 1 and the fourth bracket 6 can be assembled by the thirty-two screws 4;

[0060] Then, the two rack plates 2 are respectively arranged outside the left and right end surfaces of the working block 8, and the eight third through holes 203 of the two rack plates 2 are aligned with the eight third screw holes 802 of the working block 8, and then the eight screws 4 are passed through the eight third through holes 203 and screwed into the eight third screw holes 802.

[0062] The definition rules of the rotation direction of the rotating shaft of the meshing type molten steel sampling device provided by the utility model are as follows:

[0063] like Figures 1 to 5 As shown, since the four locking segments 1001 of the four rotating shafts 10 are inserted into the eight twelfth through holes 902 of the eight gears 9, the eight gears 9 can be driven to rotate by rotating the four rotating shafts 10, thereby driving the two rack plates 2 and the third bracket 5 to synchronously perform lifting and lowering movements; the two rotating shafts 10 located on the left side of the rack plate 2 are defined as A and B, respectively, and the two rotating shafts 10 located on the right side of the rack plate 2 are defined as C and D, respectively;

[0064] like Fig.25 As shown, by rotating A and B in the counterclockwise direction at the same time and rotating C and D in the clockwise direction at the same time, the two rack plates 2 and the third bracket 5 can be driven to rise simultaneously, so this rotation direction is defined as the positive rotation of the rotating shaft 10; on the contrary, Fig.26 As shown, by rotating A and B in the clockwise direction at the same time and rotating C and D in the counterclockwise direction at the same time, the two rack plates 2 and the third bracket 5 can be driven to descend at the same time, so this rotation direction is defined as the reverse rotation of the rotating shaft 10.

[0065] The utility model provides a technical means for realizing vacuum sampling based on the meshing type molten steel sampling device:

[0066] Since the fourth through hole 303 and the second groove 304 of the second bracket 3 are both truncated cone-shaped, and the tenth boss 1103 of the fifth bracket 11 is also truncated cone-shaped, the tenth boss 1103 of the fifth bracket 11 can just be inserted into the fourth through hole 303 and the second groove 304 of the second bracket 3; since the fourth through hole 303 and the second groove 304 of the second bracket 3 are used to hold molten steel, and the third body 301 and the third boss 302 of the second bracket 3 are immersed in the molten steel before the fifth bracket 11 is immersed in the molten steel, The tenth boss 1103 of the fifth bracket 11 is always inserted into the fourth through hole 303 and the second groove 304 of the second bracket 3. Since the tenth boss 1103 of the fifth bracket 11 can perfectly fit with the fourth through hole 303 and the second groove 304 of the second bracket 3, there is no air in the fourth through hole 303 and the second groove 304 of the second bracket 3, that is, the fourth through hole 303 and the second groove 304 of the second bracket 3 are in a vacuum state, so that the molten steel obtained will not be contaminated by the air.
