[0002] In the process of steel pipe quenching, cooling equipment is a key component. When dealing with long pipes for quenching and cooling, water cooling is usually used. However, in general, only one annular water spray pipe is set up, and the nozzle on it is used to cool the pipe. Since it is difficult to achieve rapid cooling by relying on a single annular water spray pipe, and a large amount of water vapor will be dissipated during the cooling process, the cooling effect is not good. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a steel pipe quenching cooling device, which has the characteristics of high cooling efficiency, uniform water spraying and reduced water mist.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, a steel pipe quenching cooling device includes: a frame 2, a lifting frame 3 and a sleeve 4, wherein a box 21 is arranged on the frame 2; the lifting frame 3 is slidably arranged in the box 21, and a screw 31 is rotatably arranged on the lifting frame 3, and the screw 31 is threadedly connected to the top of the box 21; the sleeve 4 is fixed on the lifting frame 3, and a plurality of mounting holes 411 arranged in a circumferential array along the axis of the sleeve 4 are opened on the sleeve 4, and a nozzle 5 is fixed in each mounting hole 411, and the nozzle of the nozzle 5 faces the axial position of the sleeve 4.

[0029] After the steel pipe is quenched, it will enter the sleeve 4 of the device. The nozzles 5 in the sleeve 4 are evenly distributed through the mounting holes 411, and can spray water to cool the steel pipe from multiple angles. The nozzles of the nozzles 5 are oriented toward the axial position of the sleeve 4 to ensure that the water flow directly impacts the surface of the steel pipe.

[0030] In the present application, steel pipes of different diameters can be transported by the same set of rollers. The height of the rollers cannot be adjusted. The height of the cylinder can be adjusted by adjusting the rotating screw 31, so that steel pipes of different diameters can be in the center position.

[0031] Since the nozzles 5 on the sleeve 4 are arranged in an axial circumferential array, uniform cooling of the steel pipe surface can be achieved, avoiding internal stress and deformation caused by uneven cooling. The parallel arrangement of multiple nozzles 5 makes the cooling efficiency high, and the temperature of the steel pipe can be quickly reduced to the required level in a short time, thereby improving production efficiency.

[0032] Specifically, the nozzle 5 is inclined toward the interior of the box body 21 .

[0033] The inwardly inclined nozzle 5 can reduce the situation where water splashes out of the outside of the sleeve 4 during the cooling process, which not only reduces the waste of water resources, but also reduces the increase in humidity in the surrounding environment, which is beneficial to maintaining the dry state around the equipment. Moreover, by controlling the direction of the water spray, the water mist generated by the contact between the water and the steel pipe can also be carried into the box body 21, which can reduce the dissipation of steam toward the outside of the box body 21.

[0034] Specifically, the outer wall of the sleeve 4 has a plurality of mounting portions 41 arranged at equal intervals, a mounting hole 411 is provided on the mounting portion 41, the mounting portion 41 is also provided with a special-shaped hole 412 connected to the mounting hole 411, and a clamping portion 51 corresponding to the special-shaped hole 412 is fixed on the nozzle 5, and the clamping portion 51 is installed in the special-shaped hole 412 to limit the rotation of the nozzle 5.

[0035] Through the docking of the clamping part 51 and the special-shaped hole 412, the nozzle 5 can be firmly fixed in a specific position after installation. This fixing method can effectively prevent the nozzle 5 from rotating or shifting under the action of the high-pressure water flow, ensuring that the cooling water is accurately sprayed to the target area of ​​the steel pipe. The clamping design makes the installation and replacement process of the nozzle 5 more convenient. The maintenance personnel can easily insert or remove the nozzle 5 from the special-shaped hole 412 without complicated tools or too much time, which is convenient for quick maintenance and troubleshooting.

[0036] Furthermore, a through hole 512 is formed on the engaging portion 51 , and a screw hole is formed in the special-shaped hole 412 . Subsequently, a bolt can be passed through the through hole 512 and threadedly connected with the screw hole to fix the nozzle 5 .

[0037] Specifically, both ends of the engaging portion 51 are in a curved shape 511 .

[0038] During installation, it is safer and has fewer sharp surfaces.

[0039] Specifically, a sealing ring 52 is fixed on the nozzle 5, and the sealing ring 52 can be sealed against the inner wall of the mounting hole 411. Good sealing performance can prevent external impurities, dust or other small particles from entering the nozzle 5, which is crucial to maintaining the normal function of the nozzle 5 and extending its service life.

[0040] Specifically, 20 nozzles 5 are installed on each mounting portion 41 , and there are 6 mounting portions 41 .

[0041] Each mounting portion 41 is equipped with 20 nozzles 5, which means that the entire device has a total of 120 nozzles 5, which provides a high-density water spray coverage for the steel pipe, ensuring a more uniform and comprehensive cooling effect. The presence of a large number of nozzles 5 makes it possible to quickly reduce the temperature of the steel pipe in a shorter period of time, which is very important in the efficient quenching process. Rapid cooling helps to form an ideal microstructure and improve the hardness and strength of the steel.

[0042] Specifically, the box body 21 is provided with an observation window 211 , and the observation window 211 is provided with a box door 212 .

[0043] The observation window 211 allows the operator to directly monitor the working conditions inside the box 21, such as the heating and cooling process of the steel pipe. The design of the box door 212 not only facilitates daily observation, but also makes maintenance and cleaning work more convenient. The operator can directly access the internal components by opening the box door 212 to clean, repair or replace parts.

[0044] Specifically, the mounting hole 411 is disposed from the outer wall of the cylinder toward the inner wall of the cylinder, and gradually approaches the inside of the box.

[0045] This design allows the nozzle 5 to be made into a straight line. During the subsequent installation process, it only needs to be directly inserted, which facilitates the installation of the nozzle 5.

[0046] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship and movement status of the components in a certain specific posture, as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
