The chain links (2) are attached to the body (1) in the form of a spiral so that a peripheral chain (4) with the hard metal bits (3) form a helical outer periphery.

Description

TOOL FOR THE CLEANING OF PIPING
FIELD OF THE INVENTION
This invention relates to a tool for the cleaning of piping, which is formed of a shaft-shaped rotatable body to which chain links are attached, on the outer periphery of which chain links there are hard metal bits that clean the piping.
BACKGROUND OF THE INVENTION
Tools that are known per se in the cleaning of piping include for example a chain knocker (Fig. 1) and a circular chain knocker (Fig 2).
The drawback of chain knockers is that, especially with larger pipe diameters, the knocker does not clean the pipe evenly because, as they rotate, the chains “whip” about and do not open properly. Thus, particularly the upper part of the pipe will remain less cleaned.
The drawback of circular chain knockers, on the other hand, is that they only clean from a very narrow area.
SUMMARY OF THE INVENTION
The object of this invention is to obviate the above-mentioned drawbacks. The tool according to the invention is characterized in that the chain links are attached to the body in the form of a spiral so that a peripheral chain with the hard metal bits form a helical outer periphery.
Different embodiments of the invention are set out in the dependent claims of the set of claims. Advantages of the solution according to the invention:
- Stability of the circular chain knocker
- Wider cleaning area of the chain knocker
- The tool according to the invention rotates stably and evenly like the circular chain knocker, but cleans the area for a long distance like the chain knocker.
The product is stable in a large area because the product works, as it rotates, in the right size and thereby may also be used for poorer-condition pipes than the old solutions.
Due to the spiral shape, the bit is not perpendicular to the pipe surface, and thereby the tool does not stick e.g. to the seams of the pipe like the circular chain knocker. This also provides a safety aspect.
Due to the spiral shape, the bit is not perpendicular to the pipe surface, and thereby the quality of the surface is better and more detailed. The product may be used, e.g., for roughening the inner surface of a plastic pipe, which is practically impossible with the prior products.
The product works properly at a lower rotating speed, and thereby the product is safer to use, requires less energy and exerts less stress on the rotating equipment as well as over the staff. Normally the products rotate at appr. 2500-3000 rpm, but the spiral works at rotational speeds of appr. 1000 - 2000 rpm.

DETAILED DESCRIPTION OF THE INVENTION
A tool for the cleaning of piping is formed of a shaft-shaped rotatable body 1 to which chain links 2 are attached, on the outer periphery of which chain links there are hard metal bits 3 that clean the piping. The chain links 2 are attached to the body in the form of a spiral so that a peripheral chain 4 with the hard metal bits 3 form a helical outer periphery. At the end of the body 1 there is an internal-thread socket 5 into which auxiliary tools, such as robot heads, 7a, 7b, 7c, 7d, 7e, 7f; Fig. 9, are attachable. Inside the body 1 there is a replaceable separate centre core 6, i.e. a connector, by which the tool may be easily adapted to be attached to different-sized wires or rods.
The tools according to the invention may be in different sizes in diameter and length. Fig. 3 - 8 illustrate embodiments of the invention. The rotatable body 1 is provided with an attachment point for the chain links 2. The rotatable body of one embodiment may be provided with a spiral flange 8.
The spiral flange 8 may be provided with attachment points 9 for the chain links 2. The attachment point 9 may be a hole formed in the spiral flange 8, in which hole the chain link 2 is arranged. According to one embodiment the attachment point 9 is a through hole formed in the spiral flange 8, which through hole extends from a first side of the spiral flange 8 to a second side of the spiral flange. The chain link 2 may be arranged in the through hole.
According to one embodiment, attachment points 9 may be spirally arranged to the body 1 at a distance from each other. According to one embodiment the attachment points 9 are arranged to the spiral flange 8 in a distributed maimer.
According to one embodiment the chain links 2 may extend in a radial direction from the attachment point 9 to the peripheral chain 4, as in the embodiment of Fig.
7. The outer end of the chain links 2 extending radially from the attachment point 9 is arranged to the peripheral chain 4. An attachment part, in Fig. 7 an attachment link, may be formed in the chain 4, to which attachment part the chain link 2 is arranged.
The spiral flange is arranged to the surface of the shaft of the rotatable body 1. The outer edge of the spiral flange 8 extends to a distance from the surface of the shaft of the body.
