The invention discloses a down pipe pulling arm for a polyurethane spraying and polyethylene winding heat insulation pipe transmission wire. The down pipe pulling arm comprises a connection plate anda retractable plate, wherein a wire cutter is fixedly arranged below the connection plate; a connection seat is fixedly arranged above the connection plate; a hand push rod is fixedly arranged in themiddle of the connection seat; a fixed plate is fixedly arranged above the inner part of the retractable plate; a wire pulling groove is fixedly arranged on the surface of the movable plate; a heat insulation pipe body is arranged in the middle of the movable plate; a transmission wire body is connected with the outer side of the heat insulation pipe body; a second open groove is formed above theconnection plate; a gear barrel is arranged below the second open groove; a third open groove is formed in a side edge of the connection plate. The down pipe pulling arm for the polyurethane sprayingand polyethylene winding heat insulation pipe transmission wire, provided by the invention, is provided with the wire cutter and the device is pushed through the hand push rod, so that the wire cuttercan cut off the transmission wire body of the surface of the heat insulation pipe body, and the transmission wire body and the heat insulation pipe body are convenient to separate.
Description
technical field [0001] The invention relates to the technical field of polyurethane spray-coated polyethylene winding heat preservation pipes, in particular to a lower pipe pulling arm used for transmission lines of polyurethane sprayed polyethylene winding heat preservation pipes. Background technique [0002] With the popularization of central cooling and heating and the development trend of energy saving and emission reduction, more and more new construction and reconstruction projects use direct-buried prefabricated insulation pipes, and polyurethane sprayed polyethylene winding insulation pipes conform to the demand and have been favored by people. Widely used, when using polyurethane sprayed polyethylene winding insulation pipe, it is often necessary to fix the transmission line on its outside. [0003] At present, the lower tube of the polyurethane sprayed polyethylene winding insulation pipe transmission line is manually removed. This method is not only time-consumin...
