Abstract
The utility model discloses a slag scraper for inside welds of a spiral steel pipe, which belongs to weld cleaning equipment, in particular to a slag removing device for inside welds of the spiral steel pipe. The slag scraper is characterized in that four rectangular slag scraping plates in the shape of a cross are welded on a bracket; a fixing ring is arranged at one end of the bracket; the big end of a T-shaped tractor shaft is mounted inside the ring; and a draw ring of a positioning conducting wire is mounted at the small end of a rotating shaft. The utility model has the beneficial effects that the slag scraper can be used for scraping residues on the inside welds conveniently in the spiral advance direction of the steel pipe; and compared with manual beating, the utility model has the advantages of improved efficiency, lightened weight and reduced noise pollution, and can remarkably improve the working conditions of workers.
Description
Technical field
The utility model belongs to weld cleaning equipment, particularly the scarfing cinder equipment of spiral steel pipe inside weld.
Background technology
Welding finishes spiral steel pipe welding unit equipment to spiral steel pipe, and some welding slags of inside weld remained on surface are to remove welding slag, and employing is manually knocked usually, inefficiency not only, and cause great noise, working environment has deteriorated significantly.
The utility model content
In order to overcome the deficiency of existing spiral steel pipe welding unit equipment, the purpose of this utility model provides a kind of spiral steel pipe inside weld slag scraper, this spiral steel pipe inside weld slag scraper is not only removed welding slag, need not manually knock, guarantee that welding slag comes off automatically, improve presentation quality, enhance productivity, and can reduce noise source, improved working environment greatly.
The technical scheme that its technical problem that solves the utility model adopts is: it is characterized in that: a kind of spiral steel pipe inside weld slag scraper, it is characterized in that: the scum board of four rectangles is cross and is welded on the support, support one end is equipped with retainer ring, the major part of T-shaped axis of traction is contained in the ring, and the positioning lead bail is housed on the rotating shaft microcephaly.
Described support is cylindrical or square cylindricality.
The method of using this slag scraper is that slag scraper is put into spiral steel pipe pulling positioning lead and made slag scraper be positioned at position while welding, and the rotation of steel pipe helical form is advanced behind the fixing cord, and slag scraper is cleaned out welding slag residual on the weld seam.
The beneficial effects of the utility model are used this slag scraper to advance along with the spiral of steel pipe and are struck off welding slag residual on the inside weld easily, more manually beat raise the efficiency, clear quality and minimizing noise pollution, can improve workman's working condition significantly.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Fig. 2 is the left view of Fig. 1.
Among the figure, 1. support, 2. scum board, 3. retainer ring, 4. T-shaped axis of traction, 5. positioning lead bail.
The specific embodiment
