DETAILED DESCRIPTION

[0017] The patent will be further described below in conjunction with specific embodiments, and it should be understood that these embodiments are only used to illustrate the patent and not to limit the scope of the patent. In addition, it should be understood that after reading the content taught by the patent, those skilled in the art can make various modifications or modifications to the patent, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0018] See Figure 1 , Figure 2 , Figure 3 and Figure 4This is a schematic diagram of the structure of this patent. A molten steel sampling cup that prevents burns includes a fixed base 1. A lead screw motor 2 is fixedly installed on the top of the fixed base 1. A screw rod 3 is fixedly installed on the top of the shaft of the lead screw motor 2. A threaded seat 4 is screwed onto the side wall of the screw rod 3. A horizontal plate 5 is fixedly installed on the left end of the threaded seat 4. The horizontal plate 5 has a through hole. A stud 6 is provided in the through hole. A nut is screwed onto the stud 6. An L-shaped rod 7 is fixedly installed on the top of the stud 6. A sampling cup 8 is fixedly installed on the bottom end of the L-shaped rod 7.

[0019] The threaded seat 4 includes an internal threaded ring 9, a riser 10, and a movable ring 13. The internal threaded ring 9 is screwed onto the side wall of the screw 3. The bottom end of the riser 10 is fixedly installed on the top of the housing of the screw motor 2. The left and right ends of the outer side wall of the riser 10 are provided with wheel grooves 11. The front and rear ends of the side wall of the riser 10 are provided with through openings. The front and rear ends of the inner side wall of the movable ring 13 are fixedly installed with one end of the connecting rod 12. The other end of the connecting rod 12 passes through the through opening and is fixedly installed on the front and rear ends of the outer side wall of the internal threaded ring 9. The left and right ends of the inner side wall of the movable ring 13 are installed with limit wheels 14, which are rolled in the wheel grooves 11.

[0020] The bottom end of the riser 10 is fixedly installed on the top of the housing of the lead screw motor 2, so the riser 10 is in a fixed state, and the length of the riser 10 matches the length of the screw 3.

[0021] Specifically, the riser 10 includes a left half pipe 15 and a right half pipe 16. The bottom ends of the left half pipe 15 and the right half pipe 16 are fixedly installed on the top of the housing of the lead screw motor 2. The left half pipe 15 and the right half pipe 16 are symmetrically distributed.

[0022] By dividing the riser 10 into a left half-pipe 15 and a right half-pipe 16, there is a gap between the left half-pipe 15 and the right half-pipe 16, which facilitates the assembly of the connecting rod 12.

[0023] Specifically, the inner threaded ring 9 has welding grooves 17 at both the front and rear ends of its outer side wall, and the movable ring 13 has welding holes 18 at both the front and rear ends of its side wall.

[0024] The welding groove 17 and welding hole 18 are provided so that the two ends of the connecting rod 12 can be welded to the welding groove 17 and welding hole 18 respectively, which facilitates the connection of the structure.

[0025] Specifically, the sampling cup 8 includes an outer cup body 19, an inner cup body 20 integrally formed inside the outer cup body 19, and a cooling medium 21 is provided inside the outer cup body 19 and the inner cup body 20.

[0026] Specifically, the inner cup body 20 is frustoconical in shape.

[0027] The molten steel fills the inner cup body 20, and then the sampling cup 8 is taken out from the steel furnace. The inner cup body 20 transfers heat to the cooling medium 21 in the outer cup body 19 and the inner cup body 20. The high-heat-conduction cup body can quickly conduct the heat of the molten steel. The inner cup body 20 is a conical frustum high-heat-conduction cup body. The conical frustum type is easy to demold. The scheme avoids oxidation of the molten steel sample in the sampling cup 8 through the vacuum treatment in advance, and quickly cools through the cooling medium 21, thereby improving the precision of the molten steel detection.

[0028] Specifically, the bottom of the outer cup body 19 is integrally formed with a conical surface 22.

[0029] The conical surface 22 is arranged to facilitate the insertion of the bottom end of the outer cup body 19 into the molten steel.

[0030] Working principle: The lead screw motor 2 drives the screw rod 3 to rotate. Since the limiting wheel 14 is rollingly installed in the wheel groove 11 outside the fixed vertical pipe 10, the inner thread ring 9 and the moving ring 13 can only move downward, driving the sampling cup 8 to move downward into the molten steel for sampling.

[0031] It should be noted that the device structure and the drawings of the patent mainly describe the principle of the patent. In the technical field of the design principle, the power mechanism, power supply system and control system of the device are not completely described, and under the premise that the person skilled in the art understands the principle of the above patent, the specific power mechanism, power supply system and control system can be clearly known.

[0032] The patent divides the threaded seat into an inner thread ring, a vertical pipe and a moving ring. The vertical pipe is in a fixed state, and the moving ring is connected to the inner thread ring through a connecting rod. The limiting wheel is rollingly installed in the outer sidewall wheel groove of the vertical pipe. Through this design, the occupied space of the lead screw system can be greatly reduced. The limiting mode is changed from the traditional sliding limiting to the rolling limiting, which can greatly reduce the friction and avoid serious wear of the parts.
