DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 ,Figure ,2, Figure 3 , Figure 4 and Figure 6The utility model provides a technical solution: a quenching and cooling device for a seamless steel pipe heating furnace, comprising a base 1, a quenching pool 2 and a blocking mechanism 3, wherein the quenching pool 2 is butted against the middle of the top of the base 1, and the outer wall of the quenching pool 2 is provided with a blocking mechanism 3, and the blocking mechanism 3 comprises a double-axis motor 301, a gear A302, a threaded rod A303, a gear ring 304, a support seat 305, a gear B306, a threaded rod B307, a threaded column 308 and a protective seat 309, a double-axis motor 301 is connected to one side of the outer wall of the quenching pool 2 through a mounting seat, and the top of the double-axis motor 301 is butted against the gear A302; the threaded rod A303 is welded inside the gear A302. 3, and the outer wall of the gear A302 is meshed with a gear ring 304; the outer wall of the gear ring 304 is slidably connected with a support seat 305, and the inner wall of the gear ring 304 is meshed with a gear B306; a threaded rod B307 is welded inside the gear B306, and the threaded rod B307 and the outer wall of the top of the threaded rod A303 are both threadedly connected with a threaded column 308; the top of the threaded column 308 is rotatably connected with a protective seat 309, and the bottom end of the threaded rod B307 is connected to the base 1 through a bearing seat; the protective seat 309 is slidably connected to the quenching pool 2, the bottom end of the support seat 305 is fixedly connected to the base 1, and the threaded rod A303 and the threaded rod B307 are parallel to each other.

[0025] In specific implementation, when the seamless steel pipe heating furnace is used and the assistance of the quenching cooling device is required, in order to prevent the quenching liquid from splashing around when the workpiece is cooled, when it needs to be blocked, the double-axis motor 301 is started first, because the output end at the top of the double-axis motor 301 is connected to the gear A302, the double-axis motor 301 starts to drive the gear A302 to rotate, and because the inside of the gear A302 is welded to the threaded rod A303, the rotation of the gear A302 drives the threaded rod A303 to rotate, and because the outer wall of the gear A302 is meshed with the gear ring 304, the gear A302 rotates to make the gear ring 304 rotate along the support seat 305;

[0026] Since the gear ring 304 is meshed with the gear B306, the gear ring 304 rotates to drive the gear B306 to rotate, and then the gear B306 rotates to drive the threaded rod B307 to rotate. Since the threaded rod A303 and the threaded rod B307 are both threadedly connected to the threaded column 308, the threaded rod A303 and the threaded rod B307 rotate to move the threaded column 308 upward, thereby generating a thrust on the protective seat 309, so that the protective seat 309 moves upward along the quenching pool 2 until the protective seat 309 automatically moves up to the designated location, and then covers the periphery of the opening of the quenching pool 2. When the quenching liquid splashes, it is blocked by the protective seat 309 to prevent the quenching liquid from splashing around when the workpiece is cooled and causing a safety accident.

[0027] And when the quenched workpiece needs to be taken out of the quenching pool 2, the dual-axis motor 301 is started to move the threaded column 308 downward, and then the protective seat 309 is moved downward to prevent the protective seat 309 from obstructing the workpiece from moving out of the quenching pool 2, causing the protective seat 309 to collide with the workpiece, thereby facilitating the blocking and not hindering the removal of the workpiece when the quenching and cooling device of the seamless steel pipe heating furnace is used.

[0028] See also Figure 2 , Figure 5 and Figure 6 It can be seen that a cleaning mechanism 4 is provided on the outer wall of the base 1, and the cleaning mechanism 4 includes a synchronous wheel A401, a synchronous belt 402, a synchronous wheel B403, a rotating column 404, a cleaning scraper 405 and a slide rail 406. The bottom end of the dual-axis motor 301 is connected to the synchronous wheel A401; the synchronous wheel A401 is connected to the synchronous wheel B403 through the synchronous belt 402, and the rotating column 404 is welded inside the synchronous wheel B403; the top of the rotating column 404 is connected to the cleaning scraper 405, and the outer wall of the cleaning scraper 405 is connected to the side of the rotating column 404 away from the rotating column 404. The slide rail 406 is fixed to the bottom end of the quenching pool 2, and the quenching pool 2 and the cleaning scraper 405 are slidably connected. The outer wall of the synchronous wheel B403 is connected to the synchronous belt 402, and the bottom end of the rotating column 404 is connected to the base 1 through the bearing seat.

[0029] In specific implementation, when the seamless steel pipe heating furnace is used and a quenching cooling device is needed for assistance, as the use time increases, a large amount of waste residue remains at the bottom of the inner wall of the quenching pool 2 and needs to be cleaned. Because the output end at the bottom of the dual-axis motor 301 is connected to the synchronous wheel A401, when the dual-axis motor 301 is started to move the protective seat 309 up and down, the dual-axis motor 301 drives the synchronous wheel A401 to rotate together, and because the synchronous wheel A401 is connected to the synchronous wheel B403 through the synchronous belt 402, when the synchronous wheel A401 rotates, it drives the synchronous wheel B403 to rotate together through the synchronous belt 402, and because the synchronous wheel B403 is internally docked with a rotating column 404, when the synchronous wheel B403 rotates, it drives the rotating column 404 to rotate together;

[0030] Because the top of the rotating column 404 is connected to the cleaning scraper rod 405, the rotation of the rotating column 404 drives the cleaning scraper rod 405 to rotate together. At this time, the cleaning scraper rod 405 rotates along the slide rail 406 on the side away from the rotating column 404, and then the rotation of the cleaning scraper rod 405 is guided by the slide rail 406. Then, during the daily operation of the quenching pool 2, the waste slag at the bottom of the quenching pool 2 is gathered together through the rotation of the cleaning scraper rod 405, which is convenient for people to carry out centralized cleaning, thereby facilitating the cleaning of residues when the quenching and cooling device of the seamless steel pipe heating furnace is used.

[0031] To sum up, when the quenching and cooling device of the seamless steel pipe heating furnace is used, the base 1 is first moved to the designated location, and then the quenching liquid is poured into the quenching pool 2, and then the seamless steel pipe to be cooled is placed in the quenching pool 2 by a crane, and then the seamless steel pipe is cooled by the quenching liquid to make it harden quickly. This is the prior art and will not be elaborated on here. The blocking mechanism 3 is used to move the protective seat 309 to the designated location, and then when the quenching liquid splashes, it is blocked by the protective seat 309 to prevent the quenching liquid from splashing everywhere and causing safety accidents, and to prevent the protective seat 309 from hindering the workpiece from moving out of the quenching pool 2, causing the protective seat 309 to collide with the workpiece. The cleaning mechanism 4 is used during the daily operation of the quenching pool 2 to gather the waste slag at the bottom of the quenching pool 2, so as to facilitate people to carry out centralized cleaning. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
