Pipeline traveling expansion and contraction descaling device

technical field

The invention relates to an expansion-contraction descaling device that can move quickly in a pipeline, so as to achieve the functions of cleaning and dredging the pipeline.

Background technique

In the application fields of machinery, chemical industry, urban pipeline network, etc., pipeline descaling is a complicated project. The principle of the pipeline descaling device currently used is as follows: one is to use high-pressure air or high-pressure water to clean, and the other is to set a A flexible shaft with a traction power device enters the pipeline for cleaning, and the third is to use a coupling with a drill bit or a cutter at the front end to enter the pipeline for guidance and cutting, but the disadvantages of these tools are: it is difficult to walk in the pipeline and the descaling effect is poor.

Contents of the invention

The object of the present invention is to provide an expansion-contraction descaling device for dredging and cleaning pipes, which has fast traveling speed, large pipe wall gripping force, and is easy to manufacture and use.

The technical solution adopted by the present invention is: including a traveling machine that cleans its inner wall while walking in the pipeline, and setting more than two traveling machines in the pipeline, and the front and rear of the traveling machine are connected by universal joints and telescopic cylinders, When walking, the first traveling machine is stretched and fixed on the inner wall of the pipeline. The telescopic cylinder is extended to drive the second traveling machine to move forward. Then the second traveling machine is stretched and fixed on the inner wall of the pipeline. The telescopic cylinder is shortened to drive the second One traveling machine moves forward; the walking of the two traveling machines in the pipeline is realized repeatedly in this way, the outer ring ends of the first traveling machine and the second traveling machine have fixed brushes and telescopic brushes, and the An expansion tube core and an air bag wrapped outside the expansion tube core are installed in the middle of the inner cavity. The expansion tube core is connected to the air hole, and the gas enters the interior through the air hole. The first traveling machine or the second traveling machine is stretched and fixed in the pipeline, and after the first traveling machine or the second traveling machine is deflated through pneumatic control, the expansion-contraction descaling device can move in the pipeline.

The invention has the advantages of simple operation, fast walking in the pipe and good descaling effect.

Detailed ways

As shown in Figure 1, a traveling machine that can walk and clean the inner wall of the pipeline 9 is set in the pipeline 9, and two or more above-mentioned traveling machines are set in the pipeline 9, the first traveling machine 13 and the second traveling machine 10 is connected by a universal joint 11 and a telescopic cylinder 12. When walking, the first traveling machine 13 is stretched and fixed on the inner wall of the pipeline 9. The telescopic cylinder 12 stretches forward to push the second traveling machine 10 forward, and then The second traveling machine 10 is stretched and fixed on the inner wall of the pipe, and the telescopic cylinder 12 is shortened to drive the first traveling machine 13 to follow up, thus repeatedly realizing the fast walking of the traveling machine in the pipeline 9 and descaling simultaneously.

As shown in Figures 2 and 3, there are fixed brushes 1 and telescopic brushes 8 at the ends of the outer rings of the second traveling machine 10 and the first traveling machine 13, the fixed brush 1 plays the role of descaling, and the telescopic brush 8 mainly plays the role of In the middle of the inner cavity of the traveling machine barrel 3, an expansion tube core 5 and an air bag 6 wrapped outside the expansion tube core 5 are installed. The expansion tube core 5 communicates with the air hole 7, and the gas enters the interior through the air hole 7, and the air pressure inflates the air bag 6 , so that all the telescopic brushes 8 are pushed out and pressed against the inner wall of the pipe 9, so that the second traveling machine 10 or the first traveling machine 13 is stretched and fixed in the pipe 9 and cannot move axially in the pipe 9, and then pass After the pneumatic control makes the second traveling machine 10 or the first traveling machine 13 deflated, the expansion-contraction descaling device can move in the pipeline 9 . The air bag 6 is wrapped outside the expansion tube core 5 and has an end face seal 2 . Another four curved blades 4 are evenly installed on the barrel body 3 of the traveling machine. When the second traveling machine 10 and the first traveling machine 13 move and turn in the pipeline, the curved blades 4 protect the fixed brush 1 and the telescopic brush 8 The role of not being deformed by excessive bending.

The mechanical part of the pipeline expansion and contraction descaling device is composed of more than two traveling machines, more than one telescopic cylinder 12 and multiple universal joints 11. The fast crawling is realized by the telescopic cylinder 12, and the telescopic brush 8 of the traveling machine Stretching and shrinking are based on air pressure to inflate the air bag 6 inside the traveling machine, and drive the telescopic brush 8 to realize expansion and contraction. The gas enters the interior of the expansion tube core 5 from the hole 7, and the air bag 6 is inflated through the holes around the expansion tube core 5. , the air bag 6 bulges to push the telescopic brush 8 to stretch out, and its contraction only needs to bleed off the gas in the air bag 6 to get final product.

The entire expansion and contraction descaling device is composed of more than 2 traveling machines, and the two traveling machines are connected to the telescopic cylinder 12 through the universal joint 11. First, the first traveling machine 13 on the right is stretched and fixed on the inner wall of the pipeline 9. The telescopic cylinder 12 is extended, driving the second traveling machine 10 on the left to move forward, and then the second traveling machine 10 on the left is stretched and fixed on the inner wall of the pipeline 9, and the telescopic cylinder 12 is shortened, driving the first traveling machine 13 on the right. Left movement; So repeatedly, has just realized the fast walking in the pipeline 9. And the expansion and contraction of the telescopic brushes 8 of the two advancing machines are to rouse the air bags 6 inside the two advancing machines by air pressure, and drive the telescopic brushes 8 to realize telescopic expansion.
