Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe cooling, and more specifically, to a cooling structure for seamless steel pipe production. Background Art

[0002] Seamless steel pipes have hollow cross-sections and are widely used as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, coal gas, water and certain solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when the bending and torsional strengths are the same. They are an economical cross-section steel material and are widely used in the manufacture of structural parts and mechanical parts. In the process of windless steel pipe rolling, there is a corresponding water immersion cooling process, and a cooling device is required to efficiently cool it. In the process of realizing the utility model, the inventor found that the following problems in the prior art have not been solved: the existing cooling device for rolling seamless steel pipes does not have the corresponding function of stable downward movement of steel pipes. The staff uses equipment to put multiple steel pipes into the cooling box at the same time. Due to the influence of water buoyancy, the steel pipes will shake, resulting in hard collision and deformation between the steel pipes, and the scrap rate is high.

[0003] In response to the above problems, there is a cooling device for rolling seamless steel pipes with a publication number of CN218982693U, which includes a box body, a support plate placed on the top of the box body, and a support plate fixedly installed on one side of the top of the box body; a plurality of groups of arc grooves in a uniform array are provided on the upper surface of the support plate, a through opening is provided on the lower side of the support plate close to the arc groove, and the through opening is connected to the arc groove, and a steel pipe is positioned in the arc groove; a forward and reverse motor is fixedly installed on the top of the support plate, a screw is connected to the bottom of the transmission shaft of the forward and reverse motor, and the top of the screw is screwed to a preset screw hole in one side of the support plate through a thread.

[0004] The cooling device of the above scheme is provided with a screw, a support plate and an arc groove. During the use of the cooling device for rolling seamless steel pipes, every time the seamless steel pipe is placed in the arc groove, the screw can be rotated counterclockwise by the forward and reverse motor, and the screw drives the support plate to move downward through the screw hole, and the support plate drives the steel pipe to move slowly downward. Water is slowly poured into the inner cavity of the steel pipe and is limited by the arc groove. Compared with the existing method of putting in multiple groups of steel pipes, it can prevent the steel pipes from colliding with each other and deforming due to the shaking of water buoyancy.

[0005] At the same time, the utility model proposes a new solution to solve the problem that when workers use equipment to put multiple steel pipes into a cooling box at the same time, the steel pipes will shake due to the buoyancy of water, causing hard collision and deformation between the steel pipes, resulting in a high scrap rate. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a cooling structure for seamless steel pipe production, which can ensure the stability of the steel pipe when placed in a cooling box and prevent the steel pipe from shaking and deforming due to collision with each other.

[0007] The above technical object of the utility model is achieved by the following technical solutions: A cooling structure for seamless steel pipe production, including a cooling box, wherein a plurality of support plates are arranged in the cooling box, a gap for the steel pipe to slide into is arranged between adjacent support plates, a plurality of equally spaced and arrayed limiting edges are arranged at one end of adjacent support plates close to each other, a support spring is arranged between adjacent support plates, a protective sleeve is arranged outside the support spring, the protective sleeve includes a first limiting sleeve and a second limiting sleeve which are slidably connected to each other, an inner cavity for the support spring to move is arranged between the first limiting sleeve and the second limiting sleeve, the support spring abuts in the inner cavity, and the first limiting sleeve and the second limiting sleeve are respectively fixed between adjacent two support plates.

[0008] By adopting the above technical solutions, the staff pours the steel pipes to be cooled into the cooling box for cooling, and the steel pipes will slide into the space between two support plates, causing the support spring between the support plates to stretch elastically. The first limiting sleeve and the second limiting sleeve outside the support spring will slide relative to each other to protect the support spring. They slide relative to each other as the support spring stretches and drives the support plates at both ends to approach or move away from each other until the steel pipe passes through the space between the two support plates. Then the steel pipe is clamped between the two support plates, and only one steel pipe can be inserted between the two support plates, so that the steel pipes are immersed in the cooling box in an array and enter the space between the two support plates in an orderly manner. At the same time, a plurality of limiting edges are arranged on the support plates to limit the steel pipes, so that each steel pipe is limited between adjacent limiting edges, and the steel pipes will not pile up in large quantities. Furthermore, there will be no collision or other impacts between the steel pipes, enabling the steel pipes to be just limited between the support plates for cooling. After cooling is completed, the staff takes out the steel pipes one by one from the cooling box. During this process, the support plates can be pushed and the support spring between the support plates can be pulled, causing the first limiting sleeve and the second limiting sleeve to slide relative to each other, facilitating the movement of the support plates in the cooling box and then the staff can take out the steel pipes. The structure is simple and convenient for the staff to handle. Then the steel pipes are restricted during cooling and can be cooled stably. At the same time, the steel pipes will not be severely collided or have depressions on the surface, ensuring the quality of the produced steel pipes.

[0009] The utility model is further arranged as: Fillets are arranged around a plurality of the limiting edges.

[0010] By adopting the above technical solutions, the arrangement of the fillets can prevent the sharp parts of the limiting edges from contacting the steel pipes and causing depressions or breakages on the surface of the steel pipes, so that the steel pipes will not be damaged when contacting the limiting edges and can be protected.

[0011] The utility model is further arranged as: Anti-slip sleeves are sleeved outside a plurality of the limiting edges.

[0012] By adopting the above technical solution, the anti-slip sleeve increases the friction between the limiting edge and the steel pipe, so that when the steel pipe contacts the limiting edge, there will be no large deviation, ensuring the stability of the steel pipe stacked in the cooling box.

[0013] The present utility model is further configured as: both the first limiting sleeve and the second limiting sleeve are fixed on the support plate by screws.

[0014] By adopting the above technical solution, the first limiting sleeve and the second limiting sleeve are fixed on the support plate by screws, which facilitates the disassembly of the first limiting sleeve and the second limiting sleeve. After disassembly, the support spring can be replaced to prevent the support spring from rusting and affecting its service life.

[0015] The present utility model is further configured as: sealing sleeves are provided on both the first limiting sleeve and the second limiting sleeve.

[0016] By adopting the above technical solution, the setting of the sealing sleeves can protect the first limiting sleeve and the second limiting sleeve, making the sealing performance better when the first limiting sleeve and the second limiting sleeve are immersed in the cooling box. Furthermore, it can protect the support springs inside the first limiting sleeve and the second limiting sleeve, increase the service life of the support springs, and prevent the support springs from rusting significantly due to excessive contact with cooling water.

[0017] The present utility model is further configured as: a driving plate is slidably connected to one end of several support plates close to the bottom wall of the cooling box. A first sliding groove for the driving plate to slide is opened between adjacent limiting edges, a second sliding groove for the driving plate to slide is opened on the support plate, and the first sliding groove and the second sliding groove are communicated.

[0018] By adopting the above technical solution, the staff can drive the cooled steel pipes in the cooling box to be taken out by sliding the driving plate, and during the movement of the driving plate, it can move along the first sliding groove opened between the limiting edges and the second sliding groove opened on the support plate, ensuring the linear movement of the driving plate. Then, as the driving plate moves, the steel pipes stacked on the driving plate are gradually moved away from the cooling box.

[0019] The present utility model is further configured as: an electric push rod for driving the driving plate to slide in the cooling box is provided on the cooling box.

[0020] By adopting the above technical solution, when the steel pipes need to be taken out after cooling, the staff can start the electric push rod to extend, driving the driving plate to move in the cooling box. Then, the driving plate can push the steel pipes in the cooling box and move the steel pipes out of the cooling box, facilitating the staff to take out the steel pipes.

[0021] The present utility model is further configured as follows: One end of the driving plate close to the inner wall of the cooling box is fixedly connected with a limiting block, and a limiting groove for the limiting block to slide is formed on the side wall of the cooling box.

[0022] By adopting the above technical solution, when the driving plate slides, it can drive the limiting block to slide, and the limiting block always slides along the inner wall of the limiting groove, thereby restricting the sliding trajectory of the driving plate, ensuring the linear motion of the driving plate, and making the electric push rod drive the driving plate more stable, ensuring that the driving plate slides more stably and smoothly in the first sliding groove and the second sliding groove.

[0023] To sum up, the present utility model has the following beneficial effects:

[0024] 1. It can ensure that the steel pipe is restricted between several support plates when placed in the cooling box, ensuring the stability of the steel pipe during cooling, and at the same time preventing the steel pipe from shaking and deforming due to mutual impact;

[0035] A driving plate 8 is slidably connected to one end of a number of support plates 2 close to the bottom wall of the cooling box 1. A first sliding groove for the driving plate 8 to slide is opened between adjacent limiting edges 3. A second sliding groove for the driving plate 8 to slide is opened on the support plate 2. The first sliding groove and the second sliding groove are communicated with each other. And an electric push rod 10 for driving the driving plate 8 to slide in the cooling box 1 is arranged on the cooling box 1.

[0036] A limiting block 9 is fixedly connected to one end of the driving plate 8 close to the inner wall of the cooling box 1. A limiting groove for the limiting block 9 to slide is opened on the side wall of the cooling box 1.

[0037] Working principle: The staff pour the steel pipes to be cooled into the cooling box 1 for cooling. The steel pipes will slide between the two support plates 2, causing the support springs 4 between the support plates 2 to stretch elastically. The first limit sleeve 5 and the second limit sleeve 6 outside the support spring 4 will slide relative to each other to protect the support spring 4. They will slide relative to each other as the support spring 4 stretches and drives the support plates 2 at both ends to approach or move away from each other until the steel pipe passes through between the two support plates 2. Then the steel pipe is clamped between the two support plates 2, and only one steel pipe can be inserted between the two support plates 2. The steel pipes are immersed in the cooling box 1 in an array and enter between the two support plates 2 in an orderly manner. At the same time, a number of limit edges 3 are provided on the support plates 2 to limit the steel pipes, so that each steel pipe is restricted between adjacent limit edges 3. Then the steel pipes will not pile up in large quantities, and there will be no collision or other impacts between the steel pipes. Just being restricted between the support plates 2 for cooling. After cooling is completed, the staff take out the steel pipes one by one from the cooling box 1. During this process, the support plates 2 can be pushed and the support springs 4 between the support plates 2 can be pulled, causing the first limit sleeve 5 and the second limit sleeve 6 to slide relative to each other, facilitating the movement of the support plates 2 in the cooling box 1 and then the staff can take out the steel pipes. The structure is simple and convenient for the staff to handle. Then the steel pipes are restricted during the cooling process and can be cooled stably.

[0038] The first limit sleeve 5 and the second limit sleeve 6 are fixed on the support plate 2 by screws 7, which facilitates the disassembly of the first limit sleeve 5 and the second limit sleeve 6. After disassembly, the support spring 4 can be replaced to prevent the support spring 4 from rusting and affecting its service life. The setting of the sealing sleeve can protect the first limit sleeve 5 and the second limit sleeve 6, making the sealing performance better when the first limit sleeve 5 and the second limit sleeve 6 are immersed in the cooling box 1. Furthermore, it protects the support spring 4 inside the first limit sleeve 5 and the second limit sleeve 6, increases the service life of the support spring 4, and prevents the support spring 4 from rusting significantly due to excessive contact with cooling water.

[0039] The staff can drive the cooled steel pipes in the cooling box 1 out of the cooling box 1 by sliding the driving plate 8. During the movement of the driving plate 8, it can move along the first chute formed between the limiting edges 3 and the second chute formed on the support plate 2, ensuring the linear movement of the driving plate 8. Then, as the driving plate 8 moves, the steel pipes stacked on the driving plate 8 gradually move away from the cooling box 1. When the steel pipes need to be taken out after cooling, the staff can start the electric push rod 10 to extend, driving the driving plate 8 to move in the cooling box 1. Thus, the driving plate 8 can push the steel pipes in the cooling box 1 and make the steel pipes move out of the cooling box 1, facilitating the staff to take out the steel pipes.

[0040] When the driving plate 8 slides, it can drive the limiting block 9 to slide, and the limiting block 9 always slides along the inner wall of the limiting groove, thus restricting the sliding trajectory of the driving plate 8, ensuring the linear movement of the driving plate 8. When the electric push rod 10 drives the driving plate 8, it will also be more stable, ensuring that the driving plate 8 slides more stably and smoothly in the first chute and the second chute.
