As the requirements for strength and corrosion resistance of components continue to increase, the application prospects of seamless steel pipes are becoming increasingly broad. In the production process of seamless steel pipes, timely cooling of the hot-rolled steel pipes is crucial.

[0003] Chinese utility model patent application number 202323520367.X provides a cooling device for producing seamless steel pipes. By setting up an installation plate, the seamless steel pipe is installed in the installation hole of the fixed plate. A telescopic rod and a spring are installed on the inner wall of the installation hole. The elasticity of the spring causes the limiting plate to limit the seamless springs of different sizes. The rotary motor is started, which drives the rotating shaft and the seamless steel pipe to rotate, so that the nozzle sprays water to cool the seamless steel pipe from all directions, thereby improving the uniformity of cooling of the seamless steel pipe.

[0004] However, during the use of the above equipment, it was found that when inserting or pulling the steel pipe from the side of the fixing plate, sufficient space needs to be reserved on the side of the fixing plate. For longer steel pipes, this operation is easily restricted by space, resulting in laborious and inefficient installation and disassembly processes. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figures 1-4 This utility model provides a cooling device for producing seamless steel pipes, including a cooling box 1 and a pipe fitting 4. A cooling component 2 is installed on the cooling box 1. A motor 3 is installed on the outside of the cooling box 1. The output end of the motor 3 is connected to a rotating shaft 31. Two symmetrical turntables 5 are installed on both ends of the rotating shaft 31. The circumference of the turntables 5 is provided with mounting grooves 52 arranged in an equidistant array. The mounting grooves 52 of the turntables 5 at both ends of the rotating shaft 31 correspond to each other and are semi-circular. An inverted L-shaped bracket 53 is fixedly installed on the outside of the turntable 5 at one end of the mounting groove 52. A guide rod 54 is provided through the bracket 53. A pressure plate 56 is fixedly installed at the bottom end of the guide rod 54. The pressure plate 56 corresponds to the mounting groove 52. The pressure plate 56 is connected to the bracket 53 by a spring 55.

[0026] The pipe fitting 4 is installed horizontally on the turntables 5 at both ends of the rotating shaft 31, and the pipe fitting 4 is installed between the pressure plate 56 and the mounting groove 52;

[0027] A limiting plate 58 is fixedly installed at the top of the guide rod 54, and the limiting plate 58 is positioned above the bracket 53;

[0028] A guide plate 57 is provided at the end of the pressure plate 56 away from the bracket 53, and the guide plate 57 is arc-shaped;

[0029] The turntable 5 is slidably mounted on the rotating shaft 31, and a positioning ring 51 is fixedly mounted in the middle of the left and right sides of the turntable 5;

[0030] Positioning holes 32 are provided at equal intervals on both ends of the rotating shaft 31, and the positioning ring 51 is connected to the positioning holes 32 by bolts.

[0031] Specifically, the cooling component 2 and the bottom structure of the cooling tank 1 are described in detail in the referenced document. The cooling component 2 mainly uses a water pump to pump water from the water tank at the bottom of the cooling tank 1 to the spray pipe and spray it out through the nozzle. The bottom of the cooling tank 1 is equipped with a filter plate and a water tank to facilitate the recycling of wastewater after cooling.

[0032] The equipment drives the rotating shaft 31 to rotate via the motor 3, and the turntables 5 at both ends of the rotating shaft 31 rotate accordingly. Under normal conditions, the pipe fitting 4 is horizontally installed between the pressure plate 56 and the mounting groove 52 of the turntable 5, and rotates together with the turntable 5. The cooling component 2 pumps water from the water tank at the bottom of the cooling box 1 to the spray pipe, and then sprays it out through the nozzle to spray and cool the rotating pipe fitting 4. The cooled wastewater is filtered through the filter plate at the bottom of the cooling box 1 and then enters the water tank to achieve circulating cooling.

[0033] Based on the length of the pipe fitting 4, the distance between the two turntables 5 is adjusted by sliding the turntable 5 on the rotating shaft 31 so that the positioning ring 51 is aligned with the corresponding positioning holes 32 at both ends of the rotating shaft 31. Then, the positioning ring 51 is connected and fixed to the positioning holes 32 with bolts, thereby determining the position of the turntable 5 to accommodate pipe fittings 4 of different lengths. This enhances the adaptability of the equipment to pipe fittings 4 of different specifications, improves the versatility of the equipment, avoids the trouble of needing to replace different equipment due to different lengths of pipe fittings 4, and reduces production costs.

[0034] During the installation of pipe fitting 4, pipe fitting 4 is moved along guide plate 57 towards mounting groove 52. During this process, pressure plate 56 moves towards the top of bracket 53 via guide rod 54, causing spring 55 to compress. This increases the gap between mounting groove 52 and pressure plate 56, facilitating pipe fitting 4 to enter mounting groove 52. Afterward, spring 55 gradually returns to its original state, pushing pressure plate 56 to fit against pipe fitting 4. At this time, spring 55 on pressure plate 56 is still in a compressed state, and pressure plate 56 has downward pressure under the elastic force of spring 55, which can firmly hold pipe fitting 4. Fixed in the mounting slot 52, the pipe fitting 4 is ensured to remain in place during the rotation of the turntable 5, thus guaranteeing the stability of the pipe fitting 4 during the cooling process and improving the cooling effect. When disassembling the pipe fitting 4, the pipe fitting 4 is lifted upward to overcome the elastic force of the spring 55, causing the pressure plate 56 to move towards the bracket 53, thereby widening the gap between the pressure plate 56 and the mounting slot 52, making it easier to remove the pipe fitting 4 from the mounting slot 52. The operation is relatively simple and reduces the disassembly difficulty compared to some complex fixing devices. At the same time, it does not require insertion from the side of the turntable 5, avoiding space limitation problems.

[0035] The guide plate 57 is arc-shaped and plays a guiding role during the installation of the pipe fitting 4, which facilitates the smooth entry of the pipe fitting 4 into the installation groove 52, improves the installation efficiency, and at the same time reduces the collision and friction between the pipe fitting 4 and the pressure plate 56, protects the surface of the pipe fitting 4 from being scratched, and helps to ensure the quality of the pipe fitting 4.

[0036] The motor 3 drives the turntable 5 to rotate, and the rotation speed of the turntable 5 is controlled. At the same time, a strong spring 55 is used to resist the gravity of the pipe 4 and the centrifugal force on the pipe 4 during rotation, thereby preventing the pipe 4 from detaching from the turntable 5 during rotation.

[0037] Working principle: Based on the length of the pipe 4 to be cooled, the distance between the two turntables 5 is adjusted by sliding the turntable 5 on the rotating shaft 31 so that the positioning ring 51 is aligned with the corresponding positioning holes 32 at both ends of the rotating shaft 31. Then, the positioning ring 51 is connected and fixed to the positioning holes 32 with bolts to determine the position of the turntable 5 to adapt to the length of the pipe 4.

[0038] The pipe fitting 4 is moved along the guide plate 57 into the mounting groove 52. During this process, the pressure plate 56 moves towards the top of the bracket 53 via the guide rod 54, causing the spring 55 to compress and increasing the gap between the mounting groove 52 and the pressure plate 56, making it easier for the pipe fitting 4 to enter the mounting groove 52. After the pipe fitting 4 enters the mounting groove 52, the spring 55 gradually returns to its original state, pushing the pressure plate 56 to fit against the pipe fitting 4. At this time, the spring 55 is still in a compressed state, and the pressure plate 56, under the elastic force of the spring 55, firmly fixes the pipe fitting 4 in the mounting groove 52.

[0039] Start motor 3. Motor 3 drives turntable 5 to rotate via shaft 31. Simultaneously, start cooling component 2. Cooling component 2 uses a water pump to pump water from the bottom water tank of cooling box 1 to the spray pipe, and then sprays it out through the nozzles to spray and cool the rotating pipe 4. The cooled wastewater is filtered through the filter plate at the bottom of cooling box 1 and then enters the water tank to achieve circulating cooling. After cooling is complete, turn off motor 3 and cooling component 2. When disassembling pipe 4, lift pipe 4 upwards to overcome the elastic force of spring 55, causing pressure plate 56 to move towards bracket 53, widening the gap between pressure plate 56 and mounting groove 52, making it easier to remove pipe 4 from mounting groove 52.
