Description

Technical Field

[0001] The utility model belongs to the technical field of grinding equipment, and particularly relates to an adaptive high-pressure pipeline chain-type grinding device. Background Technique

[0002] At present, on construction sites, workers mainly build scaffolding and stand on it to hold a angle grinder by hand to grind the rusty pipelines on both sides of the weld. This not only has low efficiency, but also has a high risk coefficient of standing on the high-altitude scaffolding for a long time. The manual grinding efficiency is low, and usually requires workers to operate repeatedly, consuming a large amount of time and manpower. Especially in the case of long pipelines or complex shapes, employee fatigue may lead to a further reduction in production efficiency. In addition, manual operation is easily affected by the technical level and physical condition of workers. Different operators may cause inconsistent grinding depths, resulting in uneven wear on the outer wall of the pipeline, increasing the difficulty of subsequent inspection and maintenance. Conventional countermeasures include increasing worker training, improving the working environment and introducing special grinding equipment to improve the grinding quality by enhancing the technical level of workers and improving the process. However, these methods have certain limitations. Training requires time and economic costs and it is difficult to see the effect in the short term. Therefore, we hope to design a grinding device with a novel structure to solve this problem. Content of the Utility Model

[0030] Please refer to Figures 1 to 4 Figures 1 to 4 , the chain plate 110 includes multiple sub-frames connected in series by hinges. A support shaft 120 is rotatably installed in the middle of the inner side of each sub-frame. The support shaft 120 is in rolling connection with the sand belt 130 on the inner side of the chain plate 110. The chain plate 110 cooperates with the support shaft 120 to support the circulating sand belt 130 so that it can rotate stably, and then complete the grinding work on the pipeline.

[0031] A rotating shaft sleeve for guiding the sand belt 130 is rotatably installed at both ends of each sub-frame, and only one rotating shaft sleeve is rotatably installed between two adjacent sub-frames.

[0032] As the first embodiment of the present utility model, in actual use, the two driving rollers 310 on the left and right sides of the driving component 300 drive the connected sand belt 130 to rotate in the same direction and at the same speed. Since the sand belt 130 rotates on the chain plate 110, and the part of the sand belt 130 on the inner side of the chain plate 110 can run stably under the support and guiding action of the support shaft 120, a good grinding effect on the pipeline can be formed. Just put the chain plate 110 with the sand belt 130 on the pipeline, and it can be moved to the designated grinding position for grinding when needed under the drive of the moving component 200.

[0033] Please refer to Figures 1 to 3, the mounting base 210 has an inverted U-shaped structure. A guide rail 211 is provided in the middle of the front inner wall and the middle of the rear inner wall of the mounting base 210. An adjustment motor 220 is installed on the left side of the upper end of the mounting base 210, and a bevel gear box 230 is installed in the middle of the upper end of the mounting base 210.

[0038] As the second embodiment of the present invention, based on the above first embodiment, in actual use, since four Mecanum wheels are installed at the lower end of the mounting base 210, based on the structural characteristics of the Mecanum wheels, the entire mounting base 210 has the performance of multi-directional movement and can be moved to any required grinding point as needed, greatly improving the flexibility of the equipment. When grinding, the user can start the adjustment motor 220 to drive the lead screw 260 to rotate through the bevel gear box 230. Under the drive of the nut and the action of the two guide wheels 330 and the two guide rails 211, the entire driving assembly 300 and the grinding assembly 100 are lifted, so that the abrasive belt 130 inside the grinding assembly 100 abuts against the point on the outer wall of the pipeline that needs to be ground. Subsequently, the driving assembly 300 can be started to drive the grinding assembly 100 to finely grind the required grinding point. After grinding is completed, the lead screw 260 is adjusted again so that the abrasive belt 130 is disengaged from the pipeline. Subsequently, the entire device can be moved to the next grinding point through the moving assembly 200 again.
