[0005] The steel pipe transfer mechanism includes a moving seat that is longitudinally connected to the slow cooling chamber, a lifting mechanism fixed on the moving seat, and a support fixed on the top of the lifting mechanism. When transferring the steel pipe, the moving seat moves to the bottom of the corresponding steel pipe, the support rises and supports the steel pipe, then the moving seat returns, and the support lowers to transfer the steel pipe to the first transverse conveying mechanism, the second transverse conveying mechanism, or the longitudinal conveying mechanism.

[0009] Furthermore, the longitudinal conveying mechanism includes supports respectively disposed at both ends of the slow cooling chamber and conveyor belts respectively rotatably connected to the two supports, with arc-shaped placement racks evenly distributed around the outer periphery of the conveyor belts.

[0010] Furthermore, the longitudinal conveying mechanism also includes two second drive motors that drive the conveyor belts respectively. The two supports are respectively provided with a drive wheel and a driven wheel at both ends. The two second drive motors are respectively located outside the slow cooling room and connected to the corresponding drive wheel.

[0019] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] Combination Figure 1 and Figure 2As shown, a slow cooling chamber structure for a continuous roller hearth solution furnace for stainless steel pipes includes a slow cooling chamber 1. The slow cooling chamber 1 has an inlet 2 and an outlet 3 at both ends, which are staggered. A first transverse conveying mechanism 4 and a second transverse conveying mechanism 5 are respectively provided in the slow cooling chamber 1 at the positions corresponding to the inlet 2 and the outlet 3. A longitudinal conveying mechanism 6 is provided in the slow cooling chamber 1 between the first transverse conveying mechanism 4 and the second transverse conveying mechanism 5. One or more pairs of steel pipe transfer mechanisms 7 are respectively provided between the two ends of the first transverse conveying mechanism 4, the second transverse conveying mechanism 5 and the longitudinal conveying mechanism 6.

[0021] The steel pipe transfer mechanism 7 includes a movable seat 8 longitudinally connected to the slow cooling chamber 1, a lifting mechanism 9 fixed on the movable seat 8, and a support 10 fixed on the top of the lifting mechanism 9. When transferring the steel pipe, the movable seat 8 moves to the bottom of the corresponding steel pipe, and then the support 10 rises and supports the steel pipe. Then the movable seat 8 returns, and the support 10 lowers to transfer the steel pipe to the first transverse conveying mechanism 4, the second transverse conveying mechanism 5, or the longitudinal conveying mechanism 6.

[0022] The working principle of the above structure is as follows: after the steel pipe is solution annealed, it is output from the outlet of the solution furnace and then transported to the first transverse conveying mechanism 4 through the feed port 2 of the slow cooling chamber 1. Under the relay of the first transverse conveying mechanism 4, the steel pipe completely enters the interior of the slow cooling chamber 1.

[0023] The moving seat 8 of the steel pipe transfer mechanism 7 moves to below the first transverse conveying mechanism 4, then lifts the steel pipe and transfers it to the input end of the longitudinal conveying mechanism 6. The longitudinal conveying mechanism 6 intermittently feeds the steel pipe to the second transverse conveying mechanism 5 according to the frequency of the steel pipe entering the slow cooling chamber 1.

[0024] When the steel pipe is at the output end of the longitudinal conveying mechanism 6, the moving seat 8 of another pair or more pairs of steel pipe transfer mechanisms 7 moves to below the output end of the longitudinal conveying mechanism 6 and supports the steel pipe, and then transfers the steel pipe to the second transverse conveying mechanism 5, which outputs the steel pipe.

[0025] The steel pipe is cooled as it moves within the slow cooling chamber 1.

[0026] The advantages of the above structure are: simple construction, allowing more steel pipes to be accommodated in the slow cooling chamber 1 for slow cooling, each steel pipe being cooled as it moves within the slow cooling chamber 1, and it can also be used in conjunction with the operation of a continuous discharge solution furnace, which is conducive to forming a continuous production line.

[0027] In another embodiment, combined Figure 1 and Figure 2 As shown, the first transverse conveying mechanism 4 and the second transverse conveying mechanism 5 both include a three-roller seat 11 and three conveying rollers 12 rotatably connected to the three-roller seat 11, and each of the conveying rollers 12 is provided with a support groove.

[0028] In another embodiment, each of the brackets is provided with anti-slip texture.

[0029] In another embodiment, combined Figure 1 and Figure 2 As shown, the first transverse conveying mechanism 4 and the second transverse conveying mechanism 5 also include a first drive motor 13. The ends of each conveying roller 12 of the first transverse conveying mechanism 4 and the second transverse conveying mechanism 5 are connected by a transmission chain. The two first drive motors 13 are respectively arranged outside the slow cooling chamber 1 and connected to the adjacent conveying roller 12.

[0030] In another embodiment, combined Figure 1 and Figure 2 As shown, the longitudinal conveying mechanism 6 includes supports 14 respectively set at both ends in the slow cooling chamber 1 and conveyor belts 15 respectively rotatably connected to the two supports 14. Arc-shaped placement racks 16 are evenly distributed on the outer periphery of the conveyor belts 15. After the steel pipe is transferred to the longitudinal conveying mechanism 6, its two ends are respectively supported on the two corresponding placement racks 16.

[0031] In another embodiment, combined Figure 1 and Figure 2 As shown, the longitudinal conveying mechanism 6 also includes two second drive motors 17 that drive the conveyor belts 15 respectively. The two supports 14 are respectively provided with a drive wheel and a driven wheel at both ends. The two second drive motors 17 are respectively located outside the slow cooling chamber 1 and connected to the corresponding drive wheel.

[0032] In another embodiment, such as Figure 1 As shown, the slow cooling chamber 1 is also provided with guide rails 18 corresponding to each movable seat 8. Each guide rail 18 is respectively set to offset the roller seat 11 and the bracket 14. The bottom of the movable seat 8 is provided with a slider corresponding to the guide rail 18. The slider matches the guide rail 18 to avoid the displacement of the movable seat 8 from affecting the operation of the first transverse conveying mechanism 4, the second transverse conveying mechanism 5 and the longitudinal conveying mechanism 6.

[0033] In another embodiment, combined Figure 1 and Figure 2 As shown, the outer side of the slow cooling chamber 1 is also provided with a plurality of first electric cylinders 19 corresponding to each movable seat 8. The telescopic rod of each first electric cylinder 19 is inserted into the slow cooling chamber 1 and connected to one end of the corresponding movable seat 8. Each first electric cylinder 19 drives the movable seat 8 to move.
