Description
Technical field
The utility model is related to special equipment field, more particularly to a kind of pressure pipeline inwall automatically grinding device.
Background technology
Pressure pipeline cause of accident mainly has burn into welding and fault in material, equipment fault, operation against rules and external force to destroy
Deng.Wherein burn into welding and fault in material rupture the accident causing and occupy very big ratio.Therefore pressure pipeline every
Some cycles should carry out periodic inspection, to detect the defects such as the burn into crackle of pressure pipeline, accident is eliminated in bud.
However as the increase of pressure pipeline use time, pressure pipeline pumped (conveying) medium not only produces rotten to pipeline body
Erosion, and be deposited on inside pipeline, the flowing of fluid is produced to be affected, or even causes the collapse of pipe-line system, simultaneously in pipeline
The analysis affecting testing result during periodic inspection judges.Therefore between pressure pipeline periodic inspection, inner-walls of duct attachment should be removed
Dielectric deposition thing and more serious iron rust, and currently without such automation derusting device, need to develop to be exclusively used in
Machine for grinding surface of inside pipe wall device people.Can enter in the destructuring pipeline environment less than people, complicated and changeable using pipe robot,
By the rust cleaning apparatus for work that carries and corresponding video detecting device, complete cleaning, rust cleaning and corresponding detection of pipeline etc.
Task, reduces the danger of manual work, mitigates the labour intensity of people, has highly important application prospect and social effect.

Change and change, thereby may be ensured that the good contact between sanding component and inner-walls of duct, sanding component row can also be overcome
The phenomenon that is hampered in entering.Another advantage of mobile centering assembly is to utilize roller, can prevent chance card during sanding component rollback
Phenomenon, its flexible characteristic can ensure that sanding component will not block in the duct.
Brief description
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is the left view structural representation of Fig. 1.
Specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
Pressure pipeline inwall automatically grinding assembly shown in the drawings, including cylindrical casing 5, is separately fixed at casing two
The mobile centering assembly of two of individual end face, be rotatably positioned casing end face sanding component and be located at casing in and pass through
Rotating shaft drives the motor 6 of sanding component；Described casing, mobile centering assembly, sanding component are coaxially arranged；
The utility model is moved and centering in the duct using mobile centering assembly；Using polishing part polishing inner-walls of duct
The dielectric deposition thing of attachment and iron rust；Polishing part includes coaxially arranged with casing and is connected with motor shaft (introducing the dynamic of motor
Power) rotating shaft, the rotation dish 12 being fixed on rotating shaft outboard end and radial equipartition several abrasive discs 7 in rotation dish；Institute
State several radial positions that abrasive disc is evenly distributed on rotation dish by telescopic spring mechanism, rotation dish is fixed on the one of rotating shaft
End, the rotating shaft other end and motor shaft are fixed and are rotated under Motor drive.
In figure：Former and later two end faces of casing fix a pedestal 4 respectively, and the radial equipartition of each pedestal has four to wheel group (8
Individual roller)；Each pair wheel group includes pressing the roller 1 of inner-walls of duct, one end is installed with roller and the other end can be inserted with radially sliding
Enter the slide bar 2 of pedestal and the spring 3 being fixed in pedestal and forcing in the outer diameter slide bar；In figure shows：Each pair wheel group
Two rollers support (slide bar end T-shaped to install two rollers) by same slide bar.Under the action of the spring, it is contained in slide bar
On roller can press inner-walls of duct along the movement of external diameter direction, also can outer internal diameter direction movement under external force so that smoothly
By bent tube section and some protrusion weld seams etc..Pass through under the promotion of connector 13 in robot, this device can cross internal diameter
The pipeline of about 140mm to 150mm and bend pipe, thus it is applicable to the pipeline of certain inside diameter ranges.
