[0040] Internal threads are respectively formed on the outer edge of the vertical cylinder 10 near the top. Threaded tubes 15 are respectively threadedly connected to the outer edge of the vertical cylinder 10 near the top through the internal threads. Expansion tubes 14 are fixedly connected to the tops of the threaded tubes 15. Circular frames 11 are fixedly connected to the tops of the expansion tubes 14. A rope 12 is inserted into the center of the top of the circular frame 11. One end of the rope 12 far from the circular frame 11 is fixedly connected to the outer edge of the vertical cylinder 10. Sector-shaped grooves are respectively formed near the left and right sides of the top of the circular frame 11. Sector-shaped plates 23 are respectively arranged on the tops of the sector-shaped grooves. A connecting tube 25 is fixedly connected to the center of the top of the circular frame 11.

Connecting elastic rods 24 are fixedly connected to the front and rear sides of two adjacent sector-shaped plates 23;

[0041] After the steel billet enters the interior of the vertical cylinder 10, the resistance heating element 13 is started. The resistance heating element 13 converts electrical energy into heat energy. The heat energy enters the interior of the vertical cylinder 10 and then is transferred to the steel billet, thereby heating the steel billet. The threaded tubes 15, the expansion tubes 14 and the circular frames 11 are located at the top of the vertical cylinder 10, sealing the top of the vertical cylinder 10, improving the heating effect of the steel billet. The vertical cylinder 10 can be used both as a heat preservation and heating device and as a conveying tool.

[0042] Working principle: When the device starts working, multiple billets are placed into the vertical cylinder 10 in sequence through external equipment. The bottom of the billet will pass through the hole inside the adjacent disc 16. The arc plate 19 inside the hole cooperates with the arc rod 21 to prevent the bottom of the billet from falling on the top of the lower disc 16, ensuring that the bottom of the billet can contact the bottom of the inner cavity of the vertical cylinder 10. If part of the billet does not completely enter the adjacent hole, the operator starts the motor 27 through an external power supply, and the motor 27 drives the transmission rod 28 to rotate, and the transmission rod 28 drives the cross plate 1 to rotate, and the cross plate 1 drives the rotating rod 30 to rotate with the transmission rod 28 as the center, and the rotating rod 30 drives the gear 29 to rotate, and the gear 29 contacts the gear ring 3, and the gear 29 itself will rotate, and the gear 29 drives The movable rotating rod 30 rotates, and the rotating rod 30 drives the limiting cylinder 4 to rotate through the limiting elastic rod 32 and the elastic vertical plate 33. The limiting cylinder 4 drives the movable cylinder 9 and the vertical cylinder 10 to rotate through the insert block 43. At the same time, when the cross plate 1 drives the rotating rod 30 to rotate with the transmission rod 28 as the center, the cross plate 1 drives the limiting cylinder 4 to rotate through the rotating rod 30. At this time, the limiting cylinder 4 can rotate with the transmission rod 28 as the center, and can rotate around the rotating rod 30 as the center. When the limiting cylinder 4 rotates with the transmission rod 28 as the center, the limiting cylinder 4 will contact the convex plate 26 at the top of the gear ring 3, and the convex plate 26 will lift the limiting cylinder 4, and the limiting cylinder 4 drives the limiting elastic rod 32 to stretch, and the limiting elastic rod 32 drives the elastic vertical plate 33 to stretch. During the lifting and falling process of the limiting cylinder 4, the inclined steel billet inside the vertical cylinder 10 will shake, thereby helping the steel billet to enter the adjacent holes. After all the steel billets have entered the vertical cylinder 10, the motor 27 is stopped, and the round frame 11 is hoisted by external equipment. The round frame 11 drives the telescopic tube 14 and the threaded tube 15 to move. The round frame 11 drives the rope 12 to stretch, and the threaded tube 15 is rotated to the top of the vertical cylinder 10. The threaded tube 15 is rotated, and the threaded tube 15 drives the telescopic tube 14 and the round frame 11 to rotate, and the threaded tube 15 is threadedly connected to the internal thread on the surface of the vertical cylinder 10, thereby limiting the threaded tube 15, the telescopic tube 14 and the round frame 11, so as to seal the vertical cylinder 10. When the threaded tube 15 is connected to the surface of the vertical cylinder 10, the top of the steel billet It will touch the top of the inner cavity of the circular frame 11. Due to the long length of the steel billet, the steel billet will drive the circular frame 11 to move upward, and the circular frame 11 will drive the telescopic tube 14 to stretch, so as to match the steel billets of different lengths. Then the operator starts the resistance heating element 13, and converts the electrical energy generated by the resistance heating element 13 into thermal energy. The thermal energy will be transmitted to the inside of the vertical cylinder 10 through the holes at the bottom of the vertical cylinder 10, and the thermal energy will be transferred to the steel billet, so as to heat the steel billet. After the heating of the steel billet is completed, it needs to be transported. The operator moves the plug block 43, and the plug block 43 drives the fixed rod 42 and the fixed disk 41 to move. The fixed disk 41 drives the limiting elastic plate 40 to stretch. The plug block 43 will be away from the groove on the surface of the movable cylinder 9, and at the same time, the vertical cylinder 10 is moved upward through external equipment.The vertical cylinder 10 drives the movable cylinder 9 to move upward. After the movable cylinder 9 moves away from the inside of the limit cylinder 4, the operator releases the insertion block 43, then rotates the bolt 37, removes the bolt 37 from the first fixed plate 35 and the second fixed plate 36, and removes the movable cylinder 9 and the resistance heating element 13 from the bottom of the vertical cylinder 10, so that the resistance heating element 13 can be maintained daily. The vertical cylinder 10 is adjusted from the vertical state to the horizontal state by an external device, and the vertical cylinder 10 is placed on the surface of the connecting plate 5. The limit L-shaped plate 7 cooperates with the vertical cylinder 10 of different lengths through the connecting elastic plate 8, and the vertical cylinder 10 will be conveyed through the inclination angle and length of the connecting plate 5. The conveying length of the connecting plate 5 is extended or shortened according to the situation. During the horizontal conveying process of the vertical cylinder 10, the threaded pipe 15 is always connected to the surface of the vertical cylinder 10, ensuring the safety and integrity of the billet conveying. The setting of the sector plate 23 can seal the inside of the vertical cylinder 10. If waste gas is generated inside the vertical cylinder 10, the operator rotates the sector plate 23. The sector plate 23 drives the T-shaped block 39 to rotate through the cross bar 38, and the sector plate 23 drives the connecting elastic rod 24 to rotate, so as to expose the groove at the top of the circular frame 11, and the waste gas will be discharged.
