[0014] Preferably, the usage method of the elastic platform includes the following steps: Step S1: Ensure the overall levelness of the floating platform by pre-compressing the first spring with a round nut and a split pin. At this time, there is still a certain gap between the positioning column and the positioning groove. When the magnesium car lifts the crystallizer to the upper limit, if there is a gap at a certain place where the crystallizer cooperates with the lower end of the reduction tank water jacket, the levelness of the crystallizer bottom changes and exerts a downward pressure on the floating platform at the upper end of the elastic platform. Under the action of the downward pressure, the first spring compresses to make the positioning column and the positioning groove fully cooperate and exert an upward supporting force on the crystallizer bottom to eliminate the gap between the crystallizer and the reduction tank water jacket. The elastic platform solves the situation of the sealing gap between the two planes of the lower bottom cover of the crystallizer carried by the furnace bottom magnesium car in the vertical tank magnesium smelting process in the magnesium reduction workshop, and improves the success rate of vacuum pumping of the reduction tank; Step S2: The movement of the floating platform drives the movement of the first rod. The movement of the first rod drives the movement of the sliding cylinder. The movement of the sliding cylinder makes the first rod drive the movement of the second spring. The movement of the second spring buffers the force when the floating platform moves. The movement of the moving head drives the movement of the pressing head. The movement of the pressing head causes the lubricating oil in the collection box to be discharged to the surface of the first support rod through the oil outlet pipe to lubricate the sliding cylinder during movement and reduce wear, realizing the function of buffering the force of the elastic platform of the reduction furnace bottom magnesium car and reducing wear during movement; Step S3: The electromagnetic block is activated to generate suction force to attract the iron block to move. The movement of the iron block drives the movement of the fifth spring. The movement of the fifth spring causes the iron block to drive the chuck to move. The movement of the chuck makes it move out of the bayonet. At this time, the electric telescopic rod moves to drive the second support rod to move. The movement of the second support rod drives the floating platform to move. After the floating platform moves to a suitable position, the electromagnetic block is turned off, and the fifth spring rebounds to snap the chuck into the bayonet, fixing the second support rod. The movement of the floating platform enables the elastic platform of the reduction furnace bottom magnesium vehicle to quickly adjust its height, realizing the function of quickly adjusting the height of the elastic platform of the reduction furnace bottom magnesium vehicle to improve its applicability; Step S4: When the guide post enters the ball head seat B, it drives the sealing ring to move. The movement of the sealing ring drives the first bracket to move. The movement of the first bracket drives the connecting rod to move. The movement of the connecting rod drives the sixth spring to move. The movement of the sixth spring causes the connecting rod to drive the buffer block to move. The movement of the buffer block makes the sealing ring in close contact with the outer surface of the guide post to make it more sealed, realizing the function of making the elastic platform of the reduction furnace bottom magnesium vehicle in contact to make it more sealed, improving the production quality and preventing air leakage.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, after the magnesium vehicle jacks up the crystallizer to reach the upper limit position, if there is a gap at a certain place where the crystallizer cooperates with the lower end of the reduction tank water jacket at this time, the levelness of the bottom of the crystallizer changes and exerts a downward pressure on the floating platform at the upper end of the elastic platform. Under the action of the downward pressure, the first spring compresses so that the positioning post and the positioning groove are fully engaged and exert an upward supporting force on the bottom of the crystallizer to eliminate the gap between the crystallizer and the reduction tank water jacket. By means of the elastic platform, the situation of the sealing gap between the two planes of the lower bottom cover of the crystallizer carried by the furnace bottom magnesium vehicle and the reduction tank water jacket in the vertical tank magnesium smelting process in the magnesium reduction workshop is solved, improving the success rate of vacuum pumping of the reduction tank; 2. In the present invention, the movement of the floating platform drives the movement of the first rod. The movement of the first rod drives the movement of the sliding cylinder. The movement of the sliding cylinder causes the first rod to drive the second spring to move. The movement of the second spring buffers the force when the floating platform moves. The movement of the moving head drives the movement of the pressing head. The movement of the pressing head causes the lubricating oil in the collection box to be discharged to the surface of the first support rod through the oil outlet pipe to lubricate the sliding cylinder when it moves, reducing wear, realizing the function of buffering the force of the elastic platform of the reduction furnace bottom magnesium vehicle and reducing wear during movement; 3. In the present invention, the electromagnetic block is activated to generate suction force to attract the iron block to move. The movement of the iron block drives the movement of the fifth spring. The movement of the fifth spring causes the iron block to drive the chuck to move. The movement of the chuck makes it move out of the bayonet. At this time, the electric telescopic rod moves to drive the second support rod to move. The movement of the second support rod drives the floating platform to move. After the floating platform moves to a suitable position, the electromagnetic block is turned off, and the fifth spring rebounds to snap the chuck into the bayonet, fixing the second support rod. The movement of the floating platform enables the elastic platform of the reduction furnace bottom magnesium vehicle to quickly adjust its height, realizing the function of quickly adjusting the height of the elastic platform of the reduction furnace bottom magnesium vehicle to improve its applicability; 4. When the guiding column installed in the present invention enters the ball head seat B, it drives the sealing ring to move. The movement of the sealing ring drives the first frame to move, the movement of the first frame drives the connecting rod to move, the movement of the connecting rod drives the sixth spring to move, and the movement of the sixth spring causes the connecting rod to drive the buffer block to move. The movement of the buffer block makes the sealing ring closely contact the outer surface of the guiding column to make it more sealed, realizing the elastic platform contact of the magnesium vehicle at the bottom of the reduction furnace to make it more sealed, improving the production quality and preventing air leakage.

The elastic platform solves the problem of the sealing gap between the two planes of the bottom cover of the crystallizer carried by the furnace bottom magnesium car and the reduction tank water jacket in the vertical tank magnesium reduction process in the magnesium reduction workshop, improving the success rate of vacuum pumping of the reduction tank; Step S2: The movement of the floating platform 2 drives the movement of the first rod 19. The movement of the first rod 19 drives the movement of the sliding cylinder 18. The movement of the sliding cylinder 18 causes the first rod 19 to drive the movement of the second spring 20. The movement of the second spring 20 buffers the force when the floating platform 2 moves. The movement of the moving head 21 drives the movement of the pressing head 23. The movement of the pressing head 23 causes the lubricating oil in the collection box 22 to be discharged to the surface of the first support rod 17 through the oil outlet pipe 24 to lubricate the sliding cylinder 18 during movement and reduce wear, realizing the function of buffering the force of the elastic platform of the reduction furnace bottom magnesium car and reducing wear during movement; Step S3: The electromagnetic block 31 is activated to generate suction to attract the iron block 34 to move. The movement of the iron block 34 drives the movement of the fifth spring 32. The movement of the fifth spring 32 causes the iron block 34 to drive the movement of the chuck 33. The movement of the chuck 33 causes it to move out of the bayonet 29. At this time, the electric telescopic rod 28 moves to drive the movement of the second support rod 27. The movement of the second support rod 27 drives the movement of the floating platform 2. After the floating platform 2 moves to a suitable position, the electromagnetic block 31 is turned off, and the fifth spring 32 rebounds to snap the chuck 33 into the bayonet 29 to fix the second support rod 27. The movement of the floating platform 2 enables the elastic platform of the reduction furnace bottom magnesium car to quickly adjust its height, realizing the function of quickly adjusting the height of the elastic platform of the reduction furnace bottom magnesium car and improving its applicability; Step S4: When the guide post 7 enters the ball head seat B6, it drives the movement of the sealing ring 41. The movement of the sealing ring 41 drives the movement of the first bracket 37. The movement of the first bracket 37 drives the movement of the connecting rod 39. The movement of the connecting rod 39 drives the movement of the sixth spring 38. The movement of the sixth spring 38 causes the connecting rod 39 to drive the movement of the buffer block 40. The movement of the buffer block 40 makes the sealing ring 41 in close contact with the outer surface of the guide post 7 to make it more sealed, realizing the function of making the elastic platform of the reduction furnace bottom magnesium car in contact to make it more sealed, improving the production quality and preventing air leakage.

[0026] Working principle: The overall levelness of the floating platform is ensured by pre-compressing the first spring 10 with the round nut 13 and the split pin 14. At this time, there is still a certain gap between the positioning column 3 and the positioning groove 4. When the magnesium car jacks the crystallizer to the upper limit, if there is a gap at a certain place where the crystallizer mates with the lower end of the reduction tank water jacket, the levelness of the crystallizer bottom changes and exerts a downward pressure on the upper floating platform 2 of the elastic platform. Under the action of the downward pressure, the first spring 10 compresses, causing the positioning column 3 to fully cooperate with the positioning groove 4 and exert an upward supporting force on the crystallizer bottom to eliminate the gap between the crystallizer and the reduction tank water jacket. Through the elastic platform, the situation of the sealing gap between the two planes of the bottom cover of the crystallizer carried by the furnace bottom magnesium car in the vertical tank magnesium reduction process in the magnesium reduction workshop is solved, improving the success rate of vacuum pumping of the reduction tank. The movement of the floating platform 2 drives the movement of the first rod 19. The movement of the first rod 19 drives the movement of the sliding cylinder 18. The movement of the sliding cylinder 18 causes the first rod 19 to drive the movement of the second spring 20. The movement of the second spring 20 buffers the force when the floating platform 2 moves. The movement of the moving head 21 drives the movement of the pressing head 23. The movement of the pressing head 23 causes the lubricating oil in the collection box 22 to be discharged through the oil outlet pipe 24 to the surface of the first support rod 17, lubricating the sliding cylinder 18 during movement and reducing wear, realizing the function of buffering the force of the elastic platform of the reduction furnace bottom magnesium car and reducing wear during movement. The electromagnetic block 31 is activated to generate suction, attracting the iron block 34 to move. The movement of the iron block 34 drives the movement of the fifth spring 32. The movement of the fifth spring 32 causes the iron block 34 to drive the movement of the chuck 33. The movement of the chuck 33 causes it to move out of the bayonet 29. At this time, the electric telescopic rod 28 moves to drive the movement of the second support rod 27. The movement of the second support rod 27 drives the movement of the floating platform 2. After the floating platform 2 moves to a suitable position, the electromagnetic block 31 is turned off, and the fifth spring 32 rebounds to snap the chuck 33 into the bayonet 29 to fix the second support rod 27. The movement of the floating platform 2 quickly adjusts the height of the elastic platform of the reduction furnace bottom magnesium car, realizing the function of quickly adjusting the height of the elastic platform of the reduction furnace bottom magnesium car and improving its applicability. When the guide post 7 enters the ball head seat B6, it drives the movement of the sealing ring 41. The movement of the sealing ring 41 drives the movement of the first frame 37. The movement of the first frame 37 drives the movement of the connecting rod 39. The movement of the connecting rod 39 drives the movement of the sixth spring 38. The movement of the sixth spring 38 causes the connecting rod 39 to drive the movement of the buffer block 40. The movement of the buffer block 40 makes the sealing ring 41 closely contact the outer surface of the guide post 7 to make it more sealed, realizing the function of making the elastic platform of the reduction furnace bottom magnesium car more sealed in contact, improving the production quality and preventing air leakage.
