Abstract

The invention provides an advancing device and an advancing method for polyurethane spraying foaming of a prefabricated directly-buried thermal insulation tube. In the polyurethane spraying foaming process of an existing prefabricated directly-buried thermal insulation tube, the steel tube is installed on a hand-cranking frame, and the advancing and rotating motions are adjusted by manpower, so that the advancing speed and the rotating speed are not uniform, the polyurethane spraying thickness is not uniform, and the polyurethane spraying density and quality are influenced. The advancing device comprises an inner chuck (1) and a polyurethane spray gun (3); the inner chuck (1) is a four-jaw linkage inner chuck; one end of the steel tube (2) is arranged on the inner chuck (2), the other endof the steel tube is connected with a driven end (4), the two ends of the steel tube sleeve with protection plates, a driven end guide rail (8) is arranged at the bottom of the driven end, the inner chuck is connected with a steel pipe autorotation power end (5) through a connecting shaft, the bottom of the polyurethane spray gun is connected with a spraying advancing power end (6), the spraying advancing power end comprises a transmission mechanism, and the transmission mechanism enables an advancing mechanism to horizontally move through chain transmission. The device is used for carrying out spraying foaming on the polyurethane of the prefabricated directly-buried thermal insulation tube.

Description

Technical field: [0001] The invention relates to a traveling device and a traveling method for polyurethane spraying and foaming of prefabricated direct-buried thermal insulation pipes. Background technique: [0002] In the process of polyurethane spraying and foaming of existing prefabricated direct-buried thermal insulation pipes, the steel pipe is installed on a simple hand crank. Polyurethane spraying density and quality, high reject rate. The uneven thickness leads to an increase in the polyurethane polishing process, which increases labor costs, reduces factory benefits, and cannot guarantee production progress. Invention content: [0003] The purpose of the present invention is to provide a traveling device and method for polyurethane spraying and foaming of prefabricated direct-buried thermal insulation pipes, specifically solving the problem of uneven traveling and rotation speed of steel pipes during polyurethane spraying and foaming of prefabricated direct-buri...
