Description

Technical Field

[0001] This utility model belongs to the field of straight seam steel pipe technology, and in particular relates to an internal blowing device for straight seam steel pipe. Background Technology

[0002] The weld seam of straight seam steel pipes is parallel to the pipe's axis, a structural characteristic that gives it significant advantages in manufacturing efficiency and cost. Its manufacturing process utilizes high-frequency welding or submerged arc welding technology, where steel strips are rolled into a tubular shape and then welded longitudinally to form a continuous, uniform weld seam.

[0003] The internal blowing device for straight seam steel pipes is used to remove residual galvanizing liquid, zinc dross, or other impurities from inside the steel pipe. In actual use, existing internal blowing devices for straight seam steel pipes work by inserting an internal blowing pipe into the steel pipe and using the holes on the internal blowing pipe to guide the gas out, thereby blowing away the debris inside the steel pipe. However, the gas is blown unevenly into the steel pipe when it is guided out through the holes, which affects the cleaning and impurity removal effect. It is also not convenient to use a drive component to rotate the internal blowing pipe for uniform cleaning. Therefore, we propose an internal blowing device for straight seam steel pipes. Summary of the Invention

[0004] In view of this, the present invention aims to propose an internal blowing device for straight seam steel pipes to solve the technical problem that it is inconvenient to use a drive component to drive the internal blowing pipe to rotate for uniform blowing.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An internal blowing device for straight seam steel pipe includes a base, a first support plate connected to the top of the base, a sliding cavity opened on the top of the base, a linear moving component installed in the sliding cavity, and the linear moving component being used to drive the first support plate to move.

[0007] A second support plate is connected to one side wall of the first support plate. A rotary joint is fixedly installed on the upper side of one side wall of the second support plate. An inner blowing pipe is fixedly connected to the outer end of the rotary joint. Multiple evenly distributed air outlets are opened at the outer end of the inner blowing pipe. An air supply pipe is fixedly fixed through the other side wall of the second support plate. The air supply pipe is connected to the rotary joint. A driving assembly is connected to the inner blowing pipe. The driving assembly is used to drive the inner blowing pipe to rotate.

[0008] It should be understood that, firstly, the inner blowpipe is aligned with the inner cavity of the steel pipe end. Then, the linear motion component drives the first and second support plates to move, thereby inserting the inner blowpipe into the inner cavity of the steel pipe. The air supply pipe guides the gas into the rotary joint and into the inner blowpipe. The gas is then discharged through the air outlet, allowing it to be blown towards the inner wall of the steel pipe for impurity removal. Furthermore, the drive component drives the inner blowpipe to rotate, making the gas discharged through the air outlet more evenly blown towards the inner wall of the steel pipe, thus improving the cleaning and impurity removal effect.

[0009] Furthermore, the drive assembly includes a servo motor, which is fixedly mounted on the upper side of one side wall of the second support plate. The outer end of the drive shaft of the servo motor is fixedly connected to a drive gear, and the outer wall of the drive gear is meshed with a driven gear. The driven gear is fixedly fitted onto the outer wall of the inner blowpipe.

[0010] It should be noted that the servo motor drives the drive gear to rotate, which in turn drives the driven gear to rotate, thereby driving the inner blowpipe to rotate, so that the gas exiting the air hole is blown more evenly onto the inner wall of the steel pipe.

[0011] Furthermore, the linear motion assembly includes a lead screw motor, which is fixedly installed on one end face of the inner cavity of the sliding cavity. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the inner wall of the sliding cavity. A suitable lead screw slider is fitted on the outer wall of the lead screw. The top of the lead screw slider is fixedly connected to the first support plate.

[0012] Specifically, the lead screw is rotated by the lead screw motor, which in turn drives the lead screw slider to move, thereby moving the first support plate and the second support plate, thus driving the inner blowpipe to penetrate deep into the inner cavity of the steel pipe for all-round cleaning and impurity removal.

[0013] Furthermore, a limiting groove is formed on one side wall of the first support plate, and a matching limiting slider is inserted into the inner cavity of the limiting groove. An electric push rod is fixedly connected to the bottom of the limiting slider, and the tail end of the electric push rod is fixedly connected to the bottom of the inner cavity of the limiting groove. The outer wall of the limiting slider is fixedly connected to the second support plate.

[0014] Specifically, the electric actuator drives the limiting slider to rise and fall within the limiting groove, thereby adjusting the height of the second support plate and thus adjusting the height of the inner blowpipe, so that it can be aligned with the steel pipe.

[0015] Furthermore, the outer end of the inner blowing tube is connected to a brushing assembly, which includes a fixed shell. Both ends of the fixed shell have movable rods that movably pass through them. The outer ends of the movable rods are fixedly connected to a brush plate. The inner cavity of the fixed shell is provided with a screw. The screw is a rod with threads on both side walls. The inner end face of the movable rod has a threaded hole. The end of the screw is inserted into the threaded hole and threadedly engaged. A second bevel gear is fixedly fitted in the middle of the screw. A first bevel gear meshes with the outer wall of the second bevel gear. A short shaft is fixedly connected to one side wall of the first bevel gear. The short shaft movably passes through the fixed shell and is fixedly connected to a rotating block.

[0016] Specifically, the rotation of the inner blowpipe drives the brush assembly to rotate, which in turn brushes the inner wall of the steel pipe inside the brush plate. This brushing followed by blowing improves the cleaning effect. Furthermore, the rotation of the rotating block drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the screw to rotate. Under the screw drive, the movable rods on both sides can move, thereby adjusting the position of the brush plates on both sides so that they can fit against the inner wall of the steel pipe, which improves adaptability.

[0017] Furthermore, bearings are fixedly fitted on both sides of the middle of the outer wall of the screw, and the outer walls of the bearings are fixedly connected to the inner wall of the fixed shell through connecting blocks.

[0018] Furthermore, mounting holes are provided at the four corners of the top of the base.

[0019] Compared with the prior art, the internal blowing device for straight seam steel pipes described in this utility model has the following beneficial effects:

[0020] The internal blowing device for straight seam steel pipe described in this utility model drives the active gear to rotate via the servo motor of the drive component, which in turn drives the driven gear to rotate, thereby enabling the internal blowing pipe to rotate. This allows the gas discharged from the air outlet to act evenly on the inner wall of the steel pipe, thus improving the cleaning and impurity removal effect.

[0021] The drive component rotates the inner blowpipe, which in turn drives the brush component to rotate. This allows the brush component to brush and then blow the inner wall of the steel pipe, thereby improving the cleaning and impurity removal effect.

[0022] Rotating the rotating block drives the first bevel gear to drive the second bevel gear to rotate, which in turn drives the screw to rotate. Under the screw drive, the movable rods on both sides move, thereby adjusting the position of the brush plates on both sides, thus adapting to steel pipes with different inner diameters and improving adaptability.

[0023] The internal blowing device for straight seam steel pipes described in this utility model uses an electric push rod to drive a limiting slider to rise and fall, thereby adjusting the height of the internal blowing pipe to adapt to the height of the seamless steel pipe, which helps to further improve adaptability.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 4 As shown in the figure, as an embodiment, the internal blowing device for straight seam steel pipe includes a base 1, a first support plate 2 connected to the top of the base 1, a sliding cavity opened on the top of the base 1, a linear moving component installed in the sliding cavity, and the linear moving component is used to drive the first support plate 2 to move.

[0036] A second support plate 21 is connected to one side wall of the first support plate 2. A rotary joint 3 is fixedly installed on the upper side of one side wall of the second support plate 21. An inner blowing pipe 31 is fixedly connected to the outer end of the rotary joint 3. Multiple evenly distributed air outlets 32 are opened at the outer end of the inner blowing pipe 31. An air supply pipe 36 is fixedly fixed through the other side wall of the second support plate 21. The air supply pipe 36 is connected to the rotary joint 3. A drive assembly is connected to the inner blowing pipe 31. The drive assembly is used to drive the inner blowing pipe 31 to rotate.

[0037] It should be understood that in actual use, the inner blow pipe 31 is first aligned with the inner cavity of the steel pipe end. Then, the linear motion component drives the first support plate 2 and the second support plate 21 to move, so that the inner blow pipe 31 is inserted into the inner cavity of the steel pipe. The air supply pipe 36 guides the gas into the rotary joint 3 and into the inner blow pipe 31. Then, the gas is discharged through the air outlet 32, so that the gas can be blown towards the inner wall of the steel pipe to remove impurities. The drive component drives the inner blow pipe 31 to rotate, so that the gas discharged from the air outlet 32 ​​is blown towards the inner wall of the steel pipe more evenly, which helps to improve the cleaning and impurity removal effect.

[0038] It is worth mentioning that mounting holes are provided at the four corners of the top of the base 1, which makes it easy to install and fix the entire device.

[0039] like Figures 1 to 2 As shown, in one embodiment, the drive assembly includes a servo motor 35, which is fixedly mounted on the upper side of one side wall of the second support plate 21. The outer end of the drive shaft of the servo motor 35 is fixedly connected to a drive gear 34, and the outer wall of the drive gear 34 is meshed with a driven gear 33, which is fixedly fitted onto the outer wall of the inner blowpipe 31.

[0040] It should be understood that the servo motor 35 drives the drive gear 34 to rotate, which in turn drives the driven gear 33 to rotate, thereby driving the inner blowpipe 31 to rotate, so that the gas discharged from the air outlet 32 ​​is blown more evenly onto the inner wall of the steel pipe.

[0041] like Figures 1 to 2 As shown in the figure, as an embodiment, the linear motion assembly includes a lead screw motor 11, which is fixedly installed on one end face of the inner cavity of the sliding cavity. A lead screw 12 is fixedly connected to the outer end of the drive shaft of the lead screw motor 11. The outer end of the lead screw 12 is rotatably connected to the inner wall of the sliding cavity. A suitable lead screw slider 13 is fitted on the outer wall of the lead screw 12. The top of the lead screw slider 13 is fixedly connected to the first support plate 2.

[0042] It should be understood that the lead screw motor 11 drives the lead screw 12 to rotate, thereby driving the lead screw slider 13 to move, thereby driving the first support plate 2 and the second support plate 21 to move, thereby driving the inner blowpipe 31 to penetrate into the inner cavity of the steel pipe for all-round blowing and impurity removal.

[0043] like Figures 1 to 2 As shown in the embodiment, a limiting groove is formed on one side wall of the first support plate 2. A matching limiting slider 22 is inserted into the inner cavity of the limiting groove. An electric push rod 23 is fixedly connected to the bottom of the limiting slider 22. The tail end of the electric push rod 23 is fixedly connected to the bottom of the inner cavity of the limiting groove. The outer wall of the limiting slider 22 is fixedly connected to the second support plate 21.

[0044] It should be understood that by driving the limit slider 22 to rise and fall within the limit groove through the electric actuator 23, the height of the second support plate 21 is adjusted, thereby adjusting the height of the inner blowpipe 31 so that it can be aligned with the steel pipe.

[0045] like Figures 1 to 4 As shown in one embodiment, the outer end of the inner blowpipe 31 is connected to a brushing assembly. The brushing assembly includes a fixed shell 4, with movable rods 41 passing through both ends of the fixed shell 4. A brush plate 42 is fixedly connected to the outer end of the movable rod 41. A screw 44 is provided in the inner cavity of the fixed shell 4. The screw 44 is a rod with threads on both side walls. A threaded hole is provided on the inner end face of the movable rod 41. The end of the screw 44 is inserted into the threaded hole and threadedly engaged. A second bevel gear 45 is fixedly fitted in the middle of the screw 44. A first bevel gear 46 is engaged on the outer wall of the second bevel gear 45. A short shaft is fixedly connected to one side wall of the first bevel gear 46. The short shaft passes through the fixed shell 4 and is fixedly connected to a rotating block 43.

[0046] It should be understood that by rotating the inner blow pipe 31, the brush assembly can be driven to rotate, thereby using the inner wall of the steel pipe inside the brush plate 42 to brush, thus achieving brushing before blowing, which helps to improve the cleaning effect. Furthermore, by rotating the rotating block 43, the first bevel gear 46 can be driven to rotate, which in turn drives the second bevel gear 45 to rotate, which in turn drives the screw 44 to rotate. Under the screw drive, the movable rods 41 on both sides can be moved, thereby adjusting the position of the brush plates 42 on both sides so that they can fit against the inner wall of the steel pipe, which helps to improve adaptability.

[0047] It should be noted that bearings are fixedly mounted on both sides of the middle of the outer wall of the screw 44. The outer wall of the bearing is fixedly connected to the inner wall of the fixed shell 4 through the connecting block. The bearing configuration makes the screw 44 highly stable in rotation.
