[0002] Steel pipes are hollow pipe fittings commonly used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, and are also an economical steel material. In real life, to meet the needs of different applications, steel pipes need to be perforated, requiring the use of appropriate perforation devices.

[0003] However, the existing steel pipe piercing devices still have the following problems when in use:

[0004] In existing technologies, when drilling steel pipes, workers need to frequently move the steel pipes to adjust the drilling position, which is cumbersome, inefficient, and labor-intensive. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a steel pipe perforation device.

At this time, the limit shaft will contact the outer wall of the steel pipe, and the anti-slip sleeve on the outer wall of the drive shaft will contact the outer wall of the steel pipe.

[0013] Start the second motor to move the drive shaft carrying the steel pipe between the two limit plates, which makes it easy to temporarily adjust the drilling position of the steel pipe. Then start the propulsion assembly to clamp and fix the steel pipe with multiple arc-shaped clamping plates so that the steel pipe will not move during the subsequent drilling process.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figure 1-4 This utility model discloses a steel pipe piercing device, including a processing table 1. The upper end of the processing table 1 is provided with a support platform 2. Multiple balls are rolled on the upper end of the support platform 2. Two limiting plates 3 are slidably arranged on the upper support platform 2 of the processing table 1. Multiple limiting shafts 13 are vertically rotatably arranged on the inner side of the limiting plates 3. Two sliding grooves 5 are provided on the symmetrical support platform 2 of the processing table 1. The lower end of the limiting plates 3 is provided with a slider 6 that is slidably connected to the sliding grooves 5. The lower end of the processing table 1 is provided with a first motor 7. The output end of the first motor 7 is provided with a rotating shaft 8. Two threaded rods 9 with reverse thread structure are symmetrically arranged on the rotating shaft 8. The two threaded rods 9 pass through the two sliders 6 respectively and are threadedly connected to the sliders 6.

[0030] The middle part of the limiting plate 3 is provided with a slot 14, and a second motor 15 is provided above the slot 14. The output end of the second motor 15 is provided with a drive shaft 16 located inside the slot 14, and the drive shaft 16 is provided with an anti-slip sleeve.

[0031] A propulsion assembly 17 is fixedly installed on the outside of the slot 14. The output end of the propulsion assembly 17 is provided with a bent rod 18. Two arc-shaped clamping plates 19 are symmetrically arranged at both ends of the bent rod 18.

[0032] A lifting assembly 10 is provided above the support platform 2. A lifting rod is provided at the output end of the lifting assembly 10. A third motor 11 is provided at the bottom end of the lifting rod. A drill bit 12 is provided at the output end of the third motor 11.

[0033] When the steel pipe piercing device is working, the steel pipe to be drilled is first placed on the support platform 2. Multiple rolling balls rolled on the upper end of the support platform 2 can reduce the friction when the steel pipe is placed, making it easier to place the steel pipe and adjust its position later.

[0034] Then, the first motor 7 is started. Since the first motor 7 is a servo motor, it can precisely control the rotation angle and speed. The output end of the first motor 7 drives the rotating shaft 8 to rotate, and the two threaded rods 9 with symmetrically arranged reverse thread structures on the rotating shaft 8 rotate accordingly. The two threaded rods 9 pass through the two sliders 6 respectively and are threadedly connected to the sliders 6. When the threaded rods 9 rotate, according to the principle of thread transmission, the two sliders 6 will move towards or away from each other along the threaded rods 9. Because the sliders 6 are located at the lower end of the limiting plate 3, the two limiting plates 3 will slide relative to each other on the symmetrical bearing platform 2 on the processing table 1, thereby achieving the clamping of the steel pipe on the bearing platform 2. During the clamping process, the multiple limiting shafts 13 vertically rotating inside the limiting plate 3 will contact the outer wall of the steel pipe. These limiting shafts 13 can restrict the radial movement of the steel pipe. At the same time, the anti-slip sleeve on the outer wall of the drive shaft 16 will also contact the outer wall of the steel pipe, playing a role in initially fixing the steel pipe.

[0035] When it is necessary to temporarily adjust the drilling position of the steel pipe, the second motor 15 is started. The second motor 15 is also a servo motor, and its output drive shaft 16 starts to rotate. Since the drive shaft 16 is equipped with an anti-slip sleeve, which contacts the outer wall of the steel pipe, when the drive shaft 16 rotates, the friction force drives the steel pipe to move between the two limit plates 3, thereby realizing the flexible adjustment of the drilling position of the steel pipe.

[0036] After the position adjustment is completed, the propulsion assembly 17 is activated. The propulsion assembly 17 uses a cylinder, and through the extension and retraction of the cylinder, its output end pushes the bent rod 18 to move. The two arc-shaped clamping plates 19 symmetrically arranged at both ends of the bent rod 18 will clamp and fix the steel pipe again.

[0037] The inner side of the arc-shaped clamping plate 19 is provided with anti-slip texture.

[0038] Because the inner side of the arc-shaped clamping plate 19 has anti-slip texture, the friction between it and the steel pipe is increased, making the steel pipe more stable during subsequent drilling and preventing it from moving easily.

[0039] Finally, the third motor 11 is started, driving the drill bit 12 to rotate. Simultaneously, the lifting assembly 10 is activated. The lifting assembly 10 uses a cylinder, and the extension and retraction of the cylinder controls the descent of the drill bit 12. The combined action of the rotation and descent of the drill bit 12 allows for drilling at the designated location on the steel pipe. Throughout the process, the multiple guide rails 4 symmetrically arranged on the upper end of the processing table 1, and the guide grooves on the limiting plate 3 pierced by the guide rails 4, play a crucial role.

[0040] Multiple guide rails 4 are symmetrically arranged on the upper end of the processing table 1. The limiting plate 3 is provided with a guide groove through which the guide rails 4 pass. The cross section of the guide rails 4 is T-shaped.

[0041] The guide rail 4 has a T-shaped cross-section. This design makes the limiting plate 3 more stable during sliding, preventing wobbling or displacement and ensuring the accuracy of the entire drilling operation.

[0042] The first motor 7, the second motor 15 and the third motor 11 are all servo motors, and the lifting assembly 10 and the propulsion assembly 17 are all cylinders.

[0043] The first motor 7, the second motor 15, and the third motor 11 are all servo motors, capable of precisely controlling rotation speed and angle; the lifting assembly 10 and the propulsion assembly 17 use cylinders, capable of precisely controlling extension and retraction length and force. This precise control can meet the piercing requirements of steel pipes of different specifications, improving the versatility and adaptability of the device.

[0044] The device has a reasonable overall structural design, and the connections and coordination between the various components are clear and easy to understand, facilitating installation, debugging, and maintenance. For example, the second motor 15 is fixed to the upper end of the limiting plate 3 by a support rod, and the bottom end of the support rod is fixed by screws. This connection method facilitates the installation and disassembly of the motor, and allows for quick repair or replacement in case of motor failure.
