Description

Pipeline cleaning tool

Technical Field

The utility model belongs to the technical field of the technique of pipeline clearance and specifically relates to a pipeline clearance frock.

Background

The casing and casing parts of an engine drive train typically comprise several different diameter and shaped conduits which function to transport oil or gas. Such parts are typically formed using a monolithic casting or 3D printing process. In the casting forming process, the sand core is embedded in the pipeline part to ensure that the pipeline is cast and formed, residues are usually adhered to the inner wall of the pipeline after the sand core is removed, and if the residues are not cleaned completely, the residues can fall off after oil or air is introduced, so that hidden danger is brought to the working safety of an engine. In the process of metal 3D printing and forming parts such as a casing, metal powder or sintered large particles are adhered to the inner wall of a pipeline, and the pipeline must be cleaned up.

The current method for cleaning the casing and the pipeline in the casing mainly comprises flexible scraper or steel ball vibration. The flexible scraper is inflexible to operate and cannot guarantee effective scraping and grinding of residues. All pipelines need to be inspected for flaw detection after the steel balls vibrate, so that the steel balls are prevented from being left, and time and labor are wasted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a pipeline cleaning tool, easy and simple to handle, flexible freedom can clear up the inside residue of pipeline fast, effectively.

The utility model provides a pipeline cleaning tool, include: the snake bone pipe 1, the steel wire 2, the brush head 3 and the telescopic device 4; wherein the content of the first and second substances,

the steel wire 2 penetrates through the snake bone pipe 1, one end of the steel wire 2 is connected with the brush head 3, the other end of the steel wire 2 is fixed on the expansion device 4, and the expansion device 4 is sleeved inside the snake bone pipe 1 and is in threaded connection with the snake bone pipe 1; the brush head 3 can be extended and retracted in the snake bone tube 1 by screwing the extension device 4.

Optionally, the wire 2 is under tension and expands towards the conduit as the wire 2 extends out of the snake 1, such that the brush head 3 of the wire 2 contacts the inner wall of the conduit.

Optionally, the surface of the brush head 3 is subjected to sand blasting treatment and is a spherical grinding tool.

Optionally, the telescopic device 4 comprises a rotating end, which is exposed outside the snake 1.

Optionally, the size of the snake bone pipe 1 is adjusted according to the distance between the part to be cleaned in the pipeline and the pipeline mouth.

Optionally, one end of the steel wire 2 is welded with the brush head 3.

The utility model provides a pipeline cleaning tool is tubular structure, and crooked nimble can stretch into different shape pipeline inside and clear up. The tool has the advantages of simple and compact structure, flexible operation and the like, and can conveniently and quickly realize the cleaning of pipelines with different shapes. Meanwhile, the inner diameter of the casing pipeline is generally not more than phi 25mm, the steel wire has large elastic opening force, and the extension length of the brush head is adjusted according to different inner diameters of the pipelines, so that the pipelines with different inner diameters can be cleaned, and the cleaning efficiency is obviously improved.

Detailed Description

Fig. 1 is the structure schematic diagram of the pipeline cleaning tool in the contracted state, and fig. 2 is the structure schematic diagram of the pipeline cleaning tool in the extended state. Referring to fig. 1 and 2, the present invention provides a pipe cleaning tool, including: snake bone pipe 1, steel wire 2, brush head 3 and telescoping device 4.

The snake bone pipe 1 is a tubular structure, the brush head 3 is welded at one end of the steel wire 2, and the other end of the steel wire 2 is connected on the telescopic device 4. The telescopic device 4 can drive the steel wire 2 and the brush head 3 to freely stretch in the snake bone pipe 1.

Optionally, the size of the snake bone pipe 1 is adjusted according to the distance between the part to be cleaned in the pipeline and the pipeline mouth. The snake bone pipe 1 comprises a plurality of small sections which are rotatably connected, and the whole snake bone pipe is in a snake shape when each small section rotates.

When the tool is used, the brush head 3 is firstly put into the snake bone pipe 1, then the tool is stretched into a pipeline to be cleaned and reaches a position to be cleaned, the brush head is stretched out of the snake bone pipe by screwing the telescopic device, the brush head is stretched by the elasticity of the steel wire, and residues on the inner wall are ground by rotating the brush head. After cleaning, the telescopic device is reversely screwed, and the brush head 3 and the steel wire 2 are collected into the snake bone pipe 1 and are drawn out from the pipeline.
