[0001] The utility model relates to pipeline processing technical field, especially a kind of polishing and grinding device for water conservancy pipeline processing. BACKGROUND

[0002] The polishing and grinding device for water conservancy pipeline processing is a kind of equipment for precision processing of various pipeline surfaces in water conservancy projects, which eliminates burrs, oxide layers or welding defects on the pipeline surface by mechanical grinding or grinding, to ensure the sealing property, corrosion resistance and fluid conveying efficiency of the pipeline. The device is widely used in pipeline manufacturing and maintenance links in municipal water supply, sewage treatment, petroleum chemical industry and other fields. In practical application, the polishing and grinding device for water conservancy pipeline processing usually needs to use the following structure:

[0003] 1. The rack is the basic support structure of the device, which needs to have enough rigidity and stability to bear various functional components;

[0004] 2. The polishing mechanism includes grinding wheel, sandpaper or grinding head, etc. The execution component directly acts on the pipeline surface to complete the polishing work;

[0005] 3. The driving system is composed of motor, transmission mechanism, etc. to provide rotation or feeding power for the polishing mechanism;

[0006] 4. The pipeline fixing clamp is used to clamp the pipeline to be processed to ensure its stability during polishing.

[0007] At present, manufacturers use various equipment and methods to achieve efficient pipeline polishing. Some manufacturers use fixed polishing devices to adjust the position of the clamp to adapt to pipelines of different diameters, but the height of the polishing mechanism is fixed, which makes it difficult to adapt to the center height requirements of pipelines of different specifications. Some manufacturers use manual screw rod adjusting structure to realize the lifting of the polishing mechanism by rotating the screw rod manually, which can meet certain adjusting requirements, but the operation is complicated and the adjusting accuracy is limited. Some manufacturers try to introduce hydraulic lifting system to drive the polishing mechanism to move vertically by using hydraulic cylinder, which improves the adjusting efficiency, but the equipment cost is high and the hydraulic system has the risk of oil leakage.

[0008] However, the above-mentioned implementation still has the following problems: in terms of universality, the polishing device with fixed structure needs to replace special clamps or adjust the overall layout for different specifications of pipelines, which makes it difficult to quickly adapt to the processing requirements of pipelines with different diameters and different installation heights, resulting in low production efficiency, increased equipment purchase cost and maintenance difficulty. To solve this problem, the present application proposes a solution, a polishing and grinding device based on electric lifting mechanism, which can quickly respond to the processing requirements of different pipelines, significantly improve the production flexibility and efficiency, and avoid the maintenance drawbacks of traditional hydraulic system.
