Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated directly buried thermal insulation pipe patching technology, in particular to a weld surface rust removal device based on the prefabricated directly buried thermal insulation pipe patching technology. Background Art

[0002] In the prefabricated direct-buried insulated pipe patching process, the notch position is usually cut off because the notch position becomes thinner, and re-welding is performed. After welding is completed, the weld surface needs to be derusted. Most of the existing weld surface derusting devices are convenient for circular welding of the weld formed by the flat cut. However, in order to improve the stability of the overall welding, bevel cutting is performed to increase the weld degree of the weld joint, thereby improving the overall stability. For this purpose, a device is designed to facilitate the prefabricated direct-buried insulated pipe to rotate and move back and forth to the right, so that the weld formed by the bevel cut continuously passes through the rust removal mechanism, thereby facilitating continuous rust removal and grinding of the circular weld formed by the bevel cut, and facilitating continuous grinding of the welds formed by the flat cut and the bevel cut, thereby reducing the limitations of use of the weld surface derusting device based on the prefabricated direct-buried insulated pipe patching process.
