[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to achieve the sealing of the oil immersion box 1 when the steel pipe is taken out, the lower surface of the closing cover 3 is provided with an oil immersion box 1, and a feed port 2 is fixed on one side surface of the oil immersion box 1. Since the feed port 2 has a certain slope, the steel pipe will automatically open the baffle 7 at the feed port and enter the carrier plate 14 inside the oil immersion box 1. A discharge port 8 is fixed on the other side surface of the oil immersion box 1. Since the discharge port 8 has a certain slope, the steel pipe will automatically slide out of the oil immersion box 1 through the discharge port 8. A positioning hole 9 is opened on the side surface of the inner wall of the oil immersion box 1, and a baffle 7 is provided on the side surface of the oil immersion box 1. A rotating shaft 21 is fixed on the side surface of the baffle 7;

[0032] There are multiple groups of positioning holes 9, which are symmetrically distributed on the inner wall side surface of the oil immersion tank 1. There are multiple groups of rotating shafts 21, which are symmetrically distributed on the side surface of the baffle 7. The rotating shafts 21 correspond to the positioning holes 9. The rotating shafts 21 are clamped in the positioning holes 9. Due to the effect of gravity, the baffle 7 can be automatically closed. The two are symmetrically distributed.

[0033] The surface of the closing cover 3 is provided with a plurality of through holes 13, which are symmetrically distributed, and the first pull rope 4 and the second pull rope 6 correspond to the through holes 13, and the first pull rope 4 and the second pull rope 6 are clamped in the through holes 13, and the three are movably connected;

[0034] The first pull rope 4 is attached to the arc surface of the first pulley 16, and the second pull rope 6 is attached to the arc surface of the second pulley 18, and the first pull rope 4 is wrapped around the arc surface of the first pulley 16. A plurality of anti-sliding blocks 19 are fixed on the surface of the first pulley 16, so the first pull rope 4 will not slip on the surface of the first pulley 16;

[0035] There are multiple groups of guide rod holes 10, which are symmetrically distributed on the surface of the first mounting block 11, and the guide rod holes 10 correspond to the guide rods 15. The guide rods 15 are clamped in the guide rod holes 10, and the two are movably connected. The first pulley 16 is fixed on the surface of the guide rod 15, so when the hanging block 5 pulls the first pull rope 4, it rotates the guide rod 15 on the motor 17, thereby pulling the carrier plate 14 up;

[0036] A fixing rod 12 is fixed on the surface of the second mounting block 20, and the second pulley 18 is sleeved on the arc surface of the fixing rod 12, and the two are movably connected. The first pulley 16 is sleeved on the arc surface of the guide rod 15, and the two are fixedly connected. A plurality of anti-sliding blocks 19 are fixed on the arc surface of the first pulley 16, so the first pull rope 4 will not slip on the surface of the first pulley 16.

[0037] It is necessary to achieve the sealing of the oil immersion box 1 when the steel pipe is taken out, and the steel pipe is placed at the feed port 2. Since the feed port 2 has a certain slope, the steel pipe will automatically open the baffle 7 at the feed port and enter the carrier plate 14 inside the oil immersion box 1. Due to the effect of gravity, the baffle 7 of the feed port 2 will automatically close to prevent dust from entering the oil immersion box 1. When the steel pipe needs to be taken out, the hanging block 5 is pulled upward. The movement of the hanging block 5 will drive the carrier plate 14 to move through the first pull rope 4 and the second pull rope 6, and the first pulley 16 is fixed on the surface of the guide rod 15. Therefore, when the hanging block 5 pulls the first pull rope 4, it rotates on the motor 17 by rotating the guide rod 15, thereby pulling the carrier plate 14 up. When the carrier plate 14 rises to the discharge port 8, stop pulling the hanging block 5. Due to the first pulley 1 6, multiple groups of anti-sliding blocks 19 are fixed on the surface, and the first pull rope 4 is wound around the surface of the first pulley 16, so the first pull rope 4 will not slip on the surface of the first pulley 16. At this time, the motor 17 is started, and the motor 17 will drive the first pulley 16 to rotate through the guide rod 15, so that the first pull rope 16 rises alone, and the carrier plate 14 is tilted. When it tilts to a certain angle, the steel pipe will slide off the surface of the carrier plate 14 and open the baffle 7 at the discharge port 8. Since the discharge port 8 has a certain slope, the steel pipe will automatically slide out of the immersion oil tank 1 through the discharge port 8. Due to the effect of gravity, the baffle 7 is automatically closed to prevent external dust from entering the immersion oil tank 1. This mechanism is simple and easy to operate, and the sealing of the immersion oil tank 1 is achieved when the steel pipe is taken out, which is conducive to improving its use effect.
