[0003] At present, right after seamless steel pipes are produced, a crane is needed to lift multiple seamless steel pipes into a cooling pool for liquid cooling. After the steel pipes are cooled, they are lifted from the cooling pool to a roller conveyor for transportation. When the crane lifts the seamless steel pipes into the cooling pool for cooling, the crane will swing left and right when using the lifting platform to lift the seamless steel pipes, which may cause the seamless steel pipes to shake from the lifting platform and even fall off. At the same time, because the crane stacks the seamless steel pipes on the lifting platform when lifting the seamless steel pipes, the seamless steel pipes need to be transferred one by one when discharging them after cooling, which is troublesome, time-consuming and labor-intensive. Therefore, we propose a steel pipe cooling mechanism to solve the above problems. Utility Model Content

A plurality of fixed plates are fixedly connected to the bottom of the cooling pool 1, and a first connecting shaft 14 and a second connecting shaft 15 are rotatably connected between the inner side wall of the inlet and outlet 10 and two adjacent fixed plates, respectively. The servo motor 13 is a common means in the prior art, and will not be described in detail here.

[0023] Two bevel gears are fixedly sleeved on the outer sides of the threaded rod 6, the first connecting shaft 14 and the second connecting shaft 15, and two adjacent bevel gears are meshed and connected. A plurality of water inlet holes 16 connected to the half-pipe groove 11 are provided at the bottom of the lifting plate 7. The distance between two adjacent half-pipe grooves 11 is the same, the distance between two adjacent cylinders 4 is the same, and the distance between two adjacent water inlet holes 16 is the same. Multiple water inlet holes 16 can make it easier for the coolant to be discharged from the half-pipe groove 11.

[0024] The functional principle of the utility model can be explained through the following operation mode: when the device is used to cool the steel pipe, firstly, the coolant is injected into the liquid inlet pipe on the inner wall of the cooling pool 1, and the liquid discharge pipe in the cooling pool 1 is in a closed state, so that the coolant can be accumulated inside the cooling pool 1;

[0025] The initial position of the lifting plate 7 is located above the coolant, and a plurality of high-temperature steel pipes to be cooled are located above a plurality of guide rollers 12 in the half-pipe groove 11. The state of the device is as follows: Figure 1 As shown, the output shaft of the servo motor 13 is started to rotate forward, and the output shaft of the servo motor 13 drives the threaded rod 6 located below to rotate;

[0026] This threaded rod 6 will drive another threaded rod 6 to rotate through the meshing of two bevel gears, and multiple threaded rods 6 will drive the lifting plate 7 to descend on the inner wall of the cooling pool 1. The lifting plate 7 will drive the high-temperature steel pipes on it that need to be cooled into the coolant, so that the high-temperature steel pipes are cooled in the coolant, and the servo motor 13 will be turned off until all the high-temperature steel pipes are cooled.
