[0057] When processing beveling of ultra-large diameter (greater than 3 meters) steel pipes, manual grinding is often used. The positioning and rotation of the steel pipe often rely on manual adjustment, which poses a great safety risk to the operator. In addition, it is inefficient and difficult to guarantee processing accuracy.

[0058] In view of this, such as Figures 1 to 3 As shown, this solution provides a fully automatic grinding device for welding bevels of ultra-large diameter steel pipes, including a positioning drive assembly 100 and a bevel grinding assembly 200.

[0059] The positioning drive assembly 100 is disposed on both sides of the steel pipe 300, including a support wheel 110, a support frame 120 and a first electric cylinder 130;

[0060] The support wheel 110 is rotatably connected to the support frame 120;

[0061] The support frame 120 is fixedly connected to the first electric cylinder 130 on the side away from the steel pipe 300;

[0062] The first electric cylinder 130 can control the support wheel 110 to move radially along the steel pipe 300;

[0063] The beveling grinding assembly 200 is located at the interface of the steel pipe 300 and includes a grinding mechanism 210;

[0064] The abrasive belt 211 of the grinding mechanism 210 is directly opposite the bevel of the steel pipe 300.

[0065] After the bevel grinding assembly 200 completes the grinding of one point, the support wheel 110, with the cooperation of multiple positioning drive assemblies 100, can control the steel pipe 300 to rotate, so that the next grinding point of the steel pipe 300 faces the bevel grinding assembly 200. After multiple rotations, the grinding of the entire bevel of the steel pipe 300 can be completed.

[0066] By using fully automated grinding equipment, direct contact between personnel and moving parts and flying debris is reduced, significantly lowering the safety risks faced by operators during processing and improving production efficiency and quality.

[0067] like Figure 3 As shown, the grinding mechanism 210 includes a grinding wheel 212, a drive wheel 213, and a drive motor 214;

[0068] The grinding wheel 212 and the drive wheel 213 are rotatably connected to the sanding belt 211, respectively.

[0069] The drive wheel 213 is fixedly connected to the output shaft of the drive motor 214;

[0070] The grinding mechanism 210 also includes a tensioner 215;

[0071] The tensioner 215 is positioned between the grinding wheel 212 and the drive wheel 213;

[0072] The grinding mechanism 210 also includes a second electric cylinder 216;

[0073] The second electric cylinder 216 is fixedly connected to the side of the grinding mechanism 210 away from the steel pipe 300;

[0074] The second electric cylinder 216 can adjust the feed speed according to the material of the steel pipe 300 and the grinding depth;

[0075] Protective plates 220 are provided on both sides of the grinding mechanism 210;

[0076] Anchor bolts 230 are provided at the lower part of the grinding mechanism 210.

[0077] Specifically, the drive motor 214 is located above the drive wheel 213 and can directly control the rotation of the drive wheel 213. The abrasive wheel 212 is the driven wheel and is located near the steel pipe 300. Both the abrasive wheel 212 and the drive wheel 213 are installed in a detachable manner. When replacing the sanding belt, the abrasive wheel 212 can be removed and the sanding belt replaced, or the sanding belt can be cut directly for replacement. The tensioning force of the tensioning wheel 215 is controlled by the compression of the tensioning spring installed in the mounting groove of the tensioning wheel 215. Setting the tensioning wheel 215 is beneficial for... Adjusting the grinding effect of the abrasive belt according to the material and size of the steel pipe 300 can improve grinding efficiency and quality. Protective plates 220 are set on both sides of the grinding mechanism 210. The size of the protective plates 220 can be adjusted according to the space of the operating site and the width of the abrasive belt to minimize the splashing of debris, which could cause environmental pollution and personal injury. The number of anchor bolts 230 can be adjusted according to the size of the bevel grinding assembly 200. By adjusting the height of the anchor bolts 230, the bevel grinding assembly 200 can be adapted to steel pipes 300 of different sizes.

[0078] like Figure 2 As shown, it also includes a dust removal component 400;

[0079] Dust removal assembly 400 includes filter 410 and suction duct 420;

[0080] The dust extraction duct 420 is directly opposite the grinding position of the steel pipe 300;

[0081] Filter 410 is connected to suction duct 420;

[0082] The vacuum duct 420 is made of flexible material.

[0083] Preferably, in order to improve the dust removal effect, the air inlet of the dust suction duct 420 can be arranged around the bevel grinding component 200, or multiple air inlets can be set to face the grinding points.

[0084] like Figure 2 and Figure 3 As shown, it also includes a control component 500 and a position sensor 600;

[0085] Control component 500 includes a touch screen and a PLC control module;

[0086] The touchscreen can display and modify grinding parameters;

[0087] The PLC control module can monitor and adjust the operating status of the grinding assembly, drive assembly and dust removal assembly 400 in real time;

[0088] Position sensor 600 is located at the lower part of the second electric cylinder 216;

[0089] The position sensor 600 can monitor the position of the grinding mechanism 210 in real time and transmit the data to the control component 500.

[0090] Specifically, the position sensor 600 transmits the collected data to the control component 500 in real time and displays it on the touch screen. Based on the data pre-set by the PLC control module, it can control the various components to work together and realize operations such as fast forward, grinding feed, and fast retraction.

[0091] This solution has at least the following beneficial effects:

[0092] 1. Improve security

[0093] By using fully automated grinding equipment, direct contact between personnel and moving parts and flying debris is reduced, significantly lowering the safety risks faced by operators during processing and improving production efficiency and quality.

[0094] 2. Improve processing efficiency and precision

[0095] The automatic control system can precisely control the grinding depth and speed, ensuring the uniformity and repeatability of the grinding process. Compared with manual operation, this method can complete the grinding task faster, and the grinding results are more consistent and accurate. In addition, the use of the positioning drive assembly 100 allows the steel pipe to automatically rotate to the next position after each grinding point is completed, thereby speeding up the overall processing speed.

[0096] 3. Adjust flexibility

[0097] By incorporating a second electric cylinder 216 and a tensioning wheel 215, the device can adjust the feed speed and tension of the abrasive belt 211 according to the different materials of the steel pipes and the required grinding depth, thereby optimizing the grinding effect. This flexibility is particularly important for handling steel pipes 300 of various specifications and materials.

[0098] 4. Improve environmental hygiene and operating environment

[0099] The dust collection assembly 400 effectively reduces the dispersion of dust and debris generated during grinding, improving the working environment and reducing environmental pollution. The design of the filter 410 and the dust extraction duct 420 ensures efficient dust collection, helping to protect the health of operators and maintain the cleanliness of the equipment.

[0100] 5. Enhance monitoring and control functions

[0101] The integrated control unit 500 and position sensor 600 allow for real-time monitoring of the grinding process, with grinding parameters displayed and adjusted via a touchscreen. The use of a PLC control module further enhances the reliability and automation of the equipment, making operation more convenient and intuitive.

[0102] In summary, this device provides an efficient, safe, and environmentally friendly solution for handling ultra-large diameter steel pipes by improving safety, efficiency, and accuracy, as well as by optimizing the operating environment and enhancing control functions. These improvements contribute to increased overall productivity and work quality while reducing long-term operating costs.
