Description
Technical field
The utility model relates to a kind of rust cleaning cleaner of steel pipe inwall.
Background technology
Existing inner-walls of duct rust cleaning is to adopt facing to pipeline to carry out acid washing method or sandblast (shot-peening) processing method.If adopt acid washing method processing for acid solution in acid cleaning process very high in the requirement aspect the environmental protection, practical operation is got up very difficult.Particularly carry out pickling at the scene, acid solution fails to wash to the greatest extent if pickling finishes the back, or the acid solution proportioning is improper, will have a strong impact on pickling effect.Adopt the blasting method rust cleaning that environmental protection and occupational health are proposed high requirement.Adopt shot-peening to carry out surface treatment, hitting power is big, and cleaning effect is obvious.But shot-peening makes workpiece deformation easily to the processing of thin plate workpiece, and shot will make metal base produce distortion after impacting surface of the work (no matter ball blast or shot-peening).Above several method all will be transported to the pickling tube immersion to steel pipe or deliver to sand blasting room and carry out sandblast, and is very inconvenient in pipeline pipe arrangement installation process.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of rust cleaning cleaner of steel pipe inwall to be provided, and it has promptness, convenience, simple and direct, characteristics such as easily row and effect be obvious.
The technical scheme that realizes above-mentioned purpose is: a kind of rust cleaning cleaner of steel pipe inwall, comprise an air grinder, to before being followed successively by air inlet, back body, the cover that keeps out the wind, precursor and emery wheel output shaft, described rust cleaning cleaner also comprises a carriage and a traction piece to the ectosome of this air grinder from the back.Wherein:
Described carriage comprises one and half lobe pipes, forward and backward supporting plate, large and small anchor ear and traction connector, and the back body of the length of described half lobe pipe and described air grinder is corresponding to the distance of precursor; Described forward and backward supporting plate is connected across two, front and back of half lobe pipe respectively; Described big anchor ear is formed by connecting by the adaptive Ω type jig of external diameter of the cover that keeps out the wind of two diameters and described abrasive machine and by bolt and nut, and this big anchor ear is fixed on the middle part of the internal face central authorities of half lobe pipe by a middle part fagging; Described little anchor ear is formed by connecting by the adaptive Ω type jig of the external diameter of the precursor of two diameters and described abrasive machine and by bolt and nut, this little anchor ear and described big anchor ear be fixed on coaxially described before on the supporting plate; Described traction connector is fixed on by a rear portion fagging between the rear portion and described rear supporting plate of internal face central authorities of described half lobe pipe;
Described traction piece is a pole or pipe, and it is installed on the described traction connector;
Connect a gland on the emery wheel output shaft of described air grinder, the some iron chains of uniform connection on the outer peripheral face of this gland, described abrasive machine is fixed on the described half lobe pipe in its mode that cover is inserted in the described big anchor ear, precursor is inserted in the described little anchor ear of keeping out the wind, and the back body of described air grinder is shelved on the described rear supporting plate.
The rust cleaning cleaner of above-mentioned a kind of steel pipe inwall, wherein, the free end of described some iron chains connects a nut respectively.
The rust cleaning cleaner of above-mentioned a kind of steel pipe inwall, wherein, the air inlet of described air grinder connects an air compressor machine by rubber tube.
The technical scheme of the rust cleaning cleaner of steel pipe inwall of the present utility model by existing air grinder is reequiped, and is fixed on the carriage that sets, and only need just can carry out the rust cleaning of steel pipe inwall in assembling back, pipeline erecting bed and clean.This device structure is simple, is convenient to transportation, all has more economy and flexibility compared with building sandblast hermetic type place and building the special-purpose pond of pickling by laying bricks or stones.It has the characteristics of promptness, convenience, simple and direct, easy row, and its great advantage is the discharging that does not have the dust of sandblast and need not to consider Acidwash solution for environment.
Description of drawings
Fig. 1 is the structural representation of the rust cleaning cleaner of steel pipe inwall of the present utility model;
Fig. 2 is the structural representation of the air grinder in the rust cleaning cleaner of steel pipe inwall of the present utility model;
Fig. 3 is the structural representation of the carriage in the rust cleaning cleaner of steel pipe inwall of the present utility model.
The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 to Fig. 3, the rust cleaning cleaner of steel pipe inwall of the present utility model comprises an air grinder 1, a carriage 2 and traction piece 3.
The ectosome of air grinder 1 extremely before is followed successively by air inlet 11, back body 12 from the back, cover 13, precursor 14 and emery wheel output shaft keep out the wind, wherein, connect a gland 15 on the emery wheel output shaft of air grinder 1, the some iron chains 16 of uniform welding on the outer peripheral face of this gland 15, the length of these iron chains 16 can be according to the internal diameter increase and decrease of steel pipe, and the free end of every iron chains 16 also connects a nut 17; The air inlet 11 of air grinder 1 connects an air compressor machine (not shown) by rubber tube 18.
The using method of the rust cleaning cleaner of steel pipe inwall of the present utility model is: the carriage 2 that will install air grinder 1 injects in the steel pipe inner chamber of required rust cleaning, starting air compressor machine rotates air grinder 1, because action of centrifugal force, iron chains 16 on the gland 15 radially stretches, and make the nut 17 on iron chains 16 free ends carry out the activity friction with the steel pipe inwall, reach the purpose of rust cleaning with this.Traction piece 3 can move around carriage 2 like a cork and slide along inner peripheral surface in steel pipe, to enlarge the rust cleaning area.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
