Abstract

The invention provides a joint coating device for a direct burial spraying winding thermal insulation pipe. The joint coating device comprises a support, a sliding sleeve and a rotating piece. The support is provided with a driving mechanism for driving the rotating piece to rotate relative to the sliding sleeve. Two fixing shafts are arranged at the front end of the rotating part in parallel, one fixing shaft is rotationally provided with a supporting roller used for supporting a hot melting belt coil, and the other fixing shaft is rotationally provided with a pressing roller used for tightly pressing and winding a hot melting belt of the hot melting belt coil on the supporting roller on a spraying winding thermal insulation pipe. In the design, the supporting roller for supporting the hot melting belt coil is arranged, and the hot melting belt of the hot melting belt coil is tightly pressed and wound on a polyurethane layer at the joint of the spraying winding thermal insulation pipeline, so that the automatic joint coating operation on the joint part of the thermal insulation pipeline is realized, manual operation is omitted, the construction efficiency is improved, and the winding uniformity of the hot melting belt is ensured.

Description

technical field [0001] The invention belongs to the field of construction and production of directly buried spraying and winding thermal insulation pipes, in particular to a mouth repairing device for directly buried spraying winding thermal insulation pipes. Background technique [0002] Now in the development of pipeline construction, the directly buried spraying and winding insulation pipe is widely used. When the directly buried spraying and winding insulation pipe is constructed, the insulation pipe has a reserved position at the end to facilitate the welding operation at the position of the pipe joint, and the welding is completed. Then, to fill the reserved position, first spray the polyurethane foam layer, and then use the hot-melt tape to wind it. After the winding is completed, use a high-temperature spray gun to heat-melt the hot-melt tape to make it closely adhere to the polyurethane foam layer. combined to achieve sealing and protection. In actual operation, be...
