Description
The utility model relates to a kind of pipeline external coating Stetch Wrapping Machine, and this Stetch Wrapping Machine is a kind of machinery that the buried pipeline corrosion-inhibiting coating is repaired at the construction field (site).
Buried pipeline repair at the construction field (site) mainly comprises operations such as peeling off, priming of excavation, old coating and external coating winding.The construction repair mainly contains manual mode and two kinds of forms of mechanical type.China generally adopts manually repair mode on the spot at present, and external coating wherein is wound up as the oil dressing liquid that manually inclines, and labor intensity is big, and coating quality is poor, and waste is serious.The external present complete machinery that generally adopts, to excavate, peel off, prime and external coating winding full mechanization, but engineering cost is very expensive, is not suitable for the pipeline rehabilitation situation of China, therefore, the pipeline external coating Stetch Wrapping Machine that needs a kind of suitable China's national situation of development.
The purpose of this utility model is to propose a kind of pipeline external coating Stetch Wrapping Machine, is used for replacing present artificial winding operation, improves coating quality, reduces labor intensity.
The purpose of this utility model is achieved in that a kind of pipeline external coating Stetch Wrapping Machine, by driving, walking, twine, heat tracing mechanism forms, a drive motor is arranged at motor scaffold top, two thrust-bearings are installed on the back-up ring of this scaffold bottom, the sheave of hinge wheel is installed between two thrust-bearings, the spin that contacts with tube wall is equipped with in the bottom of motor scaffold, reversing frame upper edge radial symmetric installation with split is coated with barrel, the strip roller, the walking wheel carrier of the adjustable helix angle of advancing, hinge wheel is fixed on the reversing frame front end by annular scaffold, hinge wheel and annular scaffold thereof have the split identical with reversing frame, the minor sprocket of motor shaft end and hinge wheel chain transmission, be coated with electric heating piece is housed in the barrel, insulation layer and guiding pivoted frame are coated with and have strip inlet and strip outlet on the barrel.The utility model is at oil (gas) pipeline not under the condition of stopping transportation, the motor driving chain drive drive on the reversing frame be coated with barrel, the strip roller is done rotation motion, when the guide mechanism of strip in tube drawn, fully soaked into anticorrosive paint, be installed in the walking wheel carrier at the adjustable spiral angle on the reversing frame, make reversing frame make helical rotation, and travel forward, realize the coating and the winding of pipeline external anti-corrosion layer along axis.
The utility model has following advantage:
Make the coating thickness of winding even owing to be coated with barrel and guide pivoted frame, no leak source, thereby the coating layer quality is improved.
Because adopt the closed barrel that is coated with, coating is in closed state substantially, and the position of hand steered support is preceding, be coated with barrel after, so working security improves greatly.
Owing to replaced manual work with mechanical work, reduced labor intensity, improve speed of application and quality, thereby reduced engineering cost.
The utility model is simple and reasonable, and is easy and simple to handle, in light weight, is suitable for on-the-spot dismounting and carrying, economizes in raw materials, and pollutes low.For example during the pipeline anticorrosion coating overhaul of 720 millimeters of diameters of Dongbei Oil Delivery Bureau, the consumption of manually twining asphalt paint is 24 tons/kilometer, use the utility model after, the consumption of coating is 14 tons/kilometer, the saving rate is 41.6%.
The utility model is described in further detail below in conjunction with drawings and Examples.
