Description
Technical field
The present invention relates to a kind of outer wall of steel pipe ballasting rust remover, a kind of that arrange and have employed guiding mechanism, can
To the steel pipe in the range of diameter 48mm--3000mm, carry out outer wall rust cleaning operation can process multi-pipe-diameter, large scale, on a large scale
Outer wall of steel pipe ballasting rust remover, belong to metal-derusting manufacture field.
Background technology
At present, the most mostly using fixed outer steel pipe wall deruster, rust remover volume is big, equipment Foundations deep, processing
Steel pipe sizes is limited, process different calibers need to change that different equipment, equipment ball blast work-room be big, steel pipe after being eliminated rust easily
Big etc. by secondary pollution, supporting dust removal machine power of motor, cause the waste of material of electric energy and device fabrication, production and processing
Put into many, efficiency is low, to this end, it is desirable to a kind of intensive, multiduty can add the steel pipe of different tube diameters
The equipment of work rust cleaning is born, to solve the more prominent defect existing for prior art.
Summary of the invention
The new technology that the purpose of the present invention is contemplated to solve above-mentioned existing distinct issues and defect and proposes
Scheme.
In order to reach to solve the purpose of above-mentioned existing problem, the technical scheme that the present invention proposes is: a kind of processing is many
Caliber large scale large-scale outer wall of steel pipe ballasting rust remover, is characterized in that: it includes guiding mechanism and adjusts motor, dust-proof
Cover and the rotation wheel apparatus etc. that steel pipe can be made to rotate and move axially, this guiding mechanism is by including each poly-ammonia
Ester scraper plate, sealing running roller (loom polyurethane rubber wheel, high wheel), adjustable protection board, each lever arm, each connector, adjustment motor institute structure
Become two groups on all four can be with the mechanism of opening and closing, two guiding mechanisms about each component, be correspondingly arranged at institute to be processed
The both sides of steel pipe, steel pipe frame to be processed is located at two groups of guiding mechanisms and ball blast operating room and rotates the top of wheel, at guiding mechanism
Central authorities be provided with ramming head motor, the ball blast operating room above electronic ramming head, and electronic ramming head being arranged on fixed mount；Also
Including being provided with from ball blast operating room the dust removing tube drawn, and enter in electronic ramming head and enter sand hopper；Guiding mechanism is installed
On support, dust cover is erected at guiding mechanism and the outside of pipe fitting to be processed.
Its feature also have: this guiding mechanism be by include polyurethane scraper plate, seal running roller, adjustable protection board, each lever arm,
Connector adjusts motor and constitutes, and adjusts motor and each lever arm and connector can be driven automatically to adjust polyurethane scraper plate, sealed roller
Wheel, adjustable protection board and the contact gap of steel pipe, adjust motor and be placed on support, and guiding mechanism is connected to one with adjusting motor
Rising, the action of guiding mechanism is relevant with the action adjusting motor.
Its feature also has: this guiding mechanism can carry out outer wall rust cleaning and make the steel pipe of caliber 48mm--3000mm scope
Industry, polyurethane scraper plate, seals running roller, adjustable protection board three and can be close on steel pipe surface, and this sealing running roller is to open
Closing, the steel pipe of the bore that varies in size can be carried out impeller blasting process, when sealing running roller and all closing, this rust remover can
So that relatively small-caliber steel pipe is carried out impeller blasting process, when sealing running roller and opening, large-diameter steel pipe can be entered by this rust remover
Row impeller blasting, the action of guiding mechanism is relevant with the action adjusting motor.
Its feature also has: this multipurpose outer wall of steel pipe ballasting rust remover and part steel pipe cover can be got up by this dust cover, anti-
Dust hood uses transparent or translucent or opaque material to make.
Its feature also has: when rotating wheel energising and rotating, steel pipe also and then rotates, and this rotation wheel has one when mounted
Fixed angle of inclination, so it when rotated, will produce a revolving force and the strength moved axially so, make steel pipe
Rotation limit, limit travels forward.
Its feature also has: this dust removing tube connects dust removal machine, and this confession sand hopper connects the husky machine under sand that carries.
The present invention compared with prior art has the following advantages and can produce obvious good effect.
1, use a tractor serves several purposes, the range of work at 48mm--3000mm, not only environmental protection, the most energy-conservation, save time, save
Power..
2, ratio current all of pipeline external rust cleaning operation equipment to be saved, material cost, and save occupation of land space.
3, also it is greatly saved supporting dust removal machine simultaneously and carries husky machine under sand.
4, it is greatly saved because the steel pipe of processing different tube diameters needs to change the working time required for distinct device.
Below in conjunction with the accompanying drawings the present invention program is described in detail.
