Topic.
Brief description
Fig. 1 is a kind of structural representation of plastic conduit inner tubal wall cleaning device.
Fig. 2 is a kind of sectional view of dragging trolley in plastic conduit inner tubal wall cleaning device.
Specific embodiment
With reference to specific embodiment, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-2, a kind of plastic conduit inner tubal wall cleaning device, including dragging trolley 1 and cleaning head 2, described drag
Draw dolly 1 to be octagonal hollow box body structure for longitudinal section, should ensure that the tank wall of dragging trolley 1 is not contacted with inner-walls of duct,
Dragging trolley 1 right side upper and lower end face is rotatably connected to two symmetrically arranged drivewheels 3, and drivewheel 3 is all arranged with rubber wheel
Circle 4, increases frictional force, is also rotatably connected to two driven pulleys 5, driven pulley more than 5 drivewheel 3 is vertically arranged on the right side of dragging trolley 1,
Some support steamboats 6 are all rotatably connected on the left of drivewheel 3 and driven pulley 5 installation side wall on dragging trolley 1, during use actively
Wheel 3 braking provides power, and driven pulley 5 supports improving stability with support steamboat 6, and rubber rim 4 increases friction it is ensured that drawing little
Car 1 can move in satiny pipeline, and different according to line size, dragging trolley 1 should produce multiple supporting models, and each type
Number drivewheel 3 between ultimate range should be slightly bigger than the internal diameter of matched pipeline, driven pulley 5 and supporting between steamboat 6
All identical with the internal diameter of ducts, the so rubber rim 4 on the drivewheel 3 when filling in dragging trolley 1 in pipeline of big distance
Extrusion, can lift the frictional force between rubber rim 4 and inner-walls of duct, it is to avoid drivewheel 3 skids further, draw little
Car 1 at drivewheel 3 and driven pulley 5 opening all fixation be sticked have sealing gasket although in pipeline residual moisture few, but sealing gasket
Safety effect can be played avoids the remaining globule to fall in dragging trolley 1；In the rotary shaft of described drivewheel 3, equal interference is connected with gear
