Description

Technical Field

[0001] The utility model relates to the technical field of steel pipes, in particular to an anti-oxidation device for steel pipe heat treatment. Background Technique

[0002] With the development of oil and gas field exploitation towards ultra-deep wells and deep seas, the demand for high-quality oil and gas pipes has increased significantly. High-quality oil and gas pipes have much higher requirements in terms of material properties and surface quality than ordinary steel pipes. They not only require good surface finish, roundness, and straightness of the outer wall, but also require good surface finish of the inner wall.

[0003] During the heat treatment of traditional steel pipes, an appropriate amount of nitrogen is introduced into the steel pipes. However, most of the existing gas filling structures are directly injected manually. Since the internal volume of the steel pipes is large, it takes a long time. During the existing steel pipe gas filling process, the steel pipes are not fixed. If the steel pipes roll, it will affect the normal filling of nitrogen. Content of the Utility Model

[0004] The purpose of the utility model is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-oxidation device for steel pipe heat treatment, including a workbench. A rectangular groove is opened on the outer wall of the top of the workbench, and a mounting plate is fixedly connected to the inner wall of the rectangular groove. A rectangular opening is opened on the outer wall of the top of the mounting plate, and a support mechanism is slidably installed in the inner wall of the rectangular opening. The support mechanism includes a support seat slidably connected in the rectangular groove and the rectangular opening. An arc-shaped groove is opened on the outer wall of the top of the support seat. Four grooves are opened on the outer wall of the top of the support seat and are distributed in a rectangle. Electric telescopic rods are fixedly connected to the inner walls of the four grooves. Arc-shaped plates are respectively fixedly connected to the output shafts of the four electric telescopic rods. The same screw rod is rotatably connected to the inner walls of both sides of the rectangular groove. The support seat is screwed on the outer wall of the screw rod.

[0006] With the above mechanism, through the support mechanism arranged on the workbench, it is convenient to support the steel pipe to avoid the problem of the steel pipe moving during the gas filling process. The arc-shaped groove in the support seat is convenient for placing the steel pipe. When the electric telescopic rod starts, it directly drives the arc-shaped plate to press against or move away from the steel pipe. Through the setting of the screw rod, it is convenient to drive the support seat to move back and forth.

[0007] A pulley one is rotatably connected to the outer wall of one side of the workbench, and one end of the transmission shaft of the pulley one is fixedly connected to the screw rod.

[0008] With the above mechanism, through the pulley one, it is convenient to directly drive the screw rod to rotate, and then drive the support seat to move.

[0009] One outer wall of the workbench is fixedly connected with a servo motor, and a second pulley is fixedly connected to the output shaft of the servo motor. The same belt is connected between the second pulley and the first pulley.

[0010] With the above mechanism, the setting of the servo motor facilitates directly driving the screw rod to rotate through the belt, and further facilitates directly driving the support seat to move.

[0011] An installation seat is fixedly connected to the top outer wall of the workbench, and an inflation pipe is fixedly connected to one outer wall of the installation seat.

[0012] With the above mechanism, the inflation pipe on the installation seat facilitates inflating the steel pipe.

[0015] A sealing box is fixedly connected to one outer wall of the workbench, an electromagnetic valve is fixedly connected to the top inner wall of the sealing box, and a pressure gauge is fixedly connected to one outer wall of the sealing box.

[0016] With the above mechanism, the setting of the sealing box facilitates storing nitrogen, and the setting of the electromagnetic valve facilitates controlling the on-off of the output of nitrogen in the sealing box.

[0017] One end of the electromagnetic valve is connected to the inflation pipe through a pipeline.

[0018] With the above mechanism, the electromagnetic valve is connected to the inflation pipe, so as to facilitate controlling the on-off of the inflation pipe through the electromagnetic valve.

[0019] An air port is formed in one outer wall of the sealing box, and a control valve is fixedly connected to the inner wall of the air port.

[0020] With the above mechanism, the setting of the control valve facilitates delivering nitrogen into the sealing box.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:
