Description

Technical Field

[0001] The invention relates to the technical field of pipeline cutting equipment, and in particular to a pipeline cutting device for water conservancy and hydropower engineering. Background Art

[0002] Existing pipe cutting equipment usually includes manual and electric types. Manual types generally rely on manual operation and are suitable for cutting small-diameter pipes. Electric cutting equipment is suitable for medium-diameter pipes. However, medium-diameter pipes usually have different diameters. The clamping mechanism in the pipe cutting equipment cannot effectively adapt to pipes of different diameters when fixing the pipe, which will cause the pipe and the clamping mechanism to be unable to adapt, and then cause the clamping force of the clamping mechanism to be insufficient when clamping the pipe, further causing displacement during the pipe cutting process, thereby affecting the cutting quality and efficiency. During cutting, it is necessary to clean up the waste foam, iron filings, etc. generated during cutting at any time to avoid affecting the cutting of the pipe. If the cutting amount is large, The operation process will not only cause a burden to the operator, but also delay the continuity of the cutting work. In addition, after the pipe is cut, the outer wall of the pipe cut usually has burrs. If it is not processed, the operator's hands may be easily injured during the hand support process. Moreover, the pipes are accumulated for a long time, and rust will be deposited on the outer wall of the pipe. If the rust deposited on the outer wall of the pipe needs to be processed when it is used, the operator not only needs to use other equipment to process it, but also needs to spend a lot of time to process it, which will further affect the progress of the work. Therefore, the present application provides a pipe cutting device for water conservancy and hydropower projects to meet the needs. Summary of the invention

The arched connecting plate 93 is arranged to facilitate the installation of the water spray pipe 96, and at the same time, it is used in conjunction with the C-shaped bent plate 98 and the supporting transverse plate 97 to block waste foam, iron filings and waste liquid to prevent waste foam, iron filings and waste liquid from overflowing. An arc-shaped supporting groove 99 is jointly provided at the middle section of the pair of supporting transverse plates 97 and the C-shaped bent plate 98. The arc-shaped supporting groove 99 and the C-shaped bent plate 98 are arranged in a cross-staggered shape. A discharge hole 910 is opened at the intersection of the C-shaped bent plate 98 and the arc-shaped supporting groove 99, and a discharge pipe is screwed on the discharge hole 910 through a thread (the discharge pipe is a prior art and is not shown in the figure).

[0026] The discharge hole 910 and the discharge pipe are provided to facilitate the collection of waste foam, iron filings and waste liquid. The support cross plate 97 is provided to assist the use of the first C-shaped clamping plate 51 and the second C-shaped clamping plate 53 to support the pipe cutting position for the convenience of pipe cutting. The C-shaped bent plate 98 is provided to locate the pipe cutting position, concentrate the waste foam, iron filings and waste liquid, and prevent the waste foam, iron filings and waste liquid from accumulating and contacting with the pipe or the cutting unit 2 to affect the cutting.

[0036] When the pipeline passes between the rolling wheel 817 and the flip wheel 826, the rolling wheel 817 and the flip wheel 826 will be forced to move outward, which will in turn cause the vertical rod 816, the third motor 815 and the mounting plate 814 to be subjected to force, and the side wing plate 824 and the second C-shaped side plate 823 to be subjected to force, further causing the first convex sliding block 812 to slide in the first convex sliding groove 811, and the second convex sliding block 822 to slide in the second convex sliding groove 821, further causing the first multi-fold elastic plate 819 and the second multi-fold elastic plate 820 to be squeezed and deformed, and at the same time, the resilience of the first multi-fold elastic plate 819 and the second multi-fold elastic plate 820 will also make the rolling wheel 817 and the flip wheel 826 fit the pipeline.

[0037] Then the third motor 815 and the fourth motor 828 start working, and the output shaft of the third motor 815 drives the vertical rod 816 to rotate through the coupling, which in turn causes the rolling wheel 817 to rotate, and the output shaft of the fourth motor 828 drives the pulley 825 to rotate. Under the action of the tensioned belt, a pair of pulleys 825 will rotate at the same time, and further the rotating rod will drive the flip wheel 826 to rotate. The rotation of the rolling wheel 817 will move the pipeline, and the rotation of the flip wheel 826 will rotate the pipeline. The sandpaper 68 will grind the surface of the pipeline in all directions.

[0038] When cutting is to be performed, the third motor 815 and the fourth motor 828 are stopped first, and the second motor 583 is started again to make it work, so that its output shaft will drive the bidirectional screw 582 to rotate again, and then the nut 584 will be driven (this is the prior art and is not described in detail in this application document), and further a pair of first C-shaped clamping plates 51 will be close to each other with the cooperation of the convex slide rail 57 and the slide groove, and further the second C-shaped clamping plate 53 and the grinding unit 6 will move together, so that the C-shaped pressure plate 63 will be further squeezed, and the curved spring plate 62 and the C-shaped spring plate 65 will be further deformed, so that the sandpaper 68 will conflict with the pipe, and then the second motor 583 will be stopped, so that the pipe is fixed.

[0039] When the cutting is completed, the pipe is released and the third motor 815 and the fourth motor 828 are started. The pipe will continue to rotate and move. When the pipe cut passes through a pair of first C-shaped clamping plates 51 at the other end, the sandpaper 68 will grind the outer wall of the pipe cut.

[0040] If the sandpaper 68 needs to be replaced, the pressure plate is turned over to make the limiting sleeve rotate so that it does not conflict with the sandpaper 68, and then the sandpaper 68 is taken down for replacement, and then the new sandpaper 68 is passed through the second waist-shaped hole 67 and between the limiting sleeve and the weakened groove 64, and then the pressure plate is turned over to return to its original position, which will fix the sandpaper 68 again.

[0041] Compared with the existing pipe cutting device, the present invention can not only adapt to clamp pipes of different diameters, but also adapt to process the rust on the outer wall of pipes of different diameters and the burrs on the outer wall of the cut mouth, and can also convey the pipe, which not only avoids the operator's hand injuries due to burrs, reduces the subsequent processing work of the pipe after cutting, solves the problem of insufficient clamping force and inability to adapt to use of the clamping mechanism when clamping the pipe, enhances the quality and efficiency of pipe cutting, reduces manpower and material resources, and improves work efficiency.

[0042] The working principle of the technical solution provided by the present invention is as follows: when in use, the first C-shaped clamping plate 51 and the second C-shaped clamping plate 53 can be adjusted according to the different diameters of the pipe. During the process, the second motor 583 starts to work, and its output shaft drives the pulley a to rotate. Under the action of the tensioned belt, a pair of pulleys a will rotate at the same time, and the pulley a will drive the bidirectional screw 582 to rotate, thereby driving the nut 584 (this is a prior art and is not described in detail in this application document). Further, the pair of first C-shaped clamping plates 51 will move away from or towards each other under the cooperation of the convex slide rail 57 and the slide groove. The second motor 583 is stopped after adjustment, and the pipe is passed through a pair of second C-shaped clamping plates 53, so that the pipe contacts the sandpaper 68. The pipe squeezes the sandpaper 68 and the C-shaped pressure plate 63, and the C-shaped pressure plate 63 is deformed with the weakened groove 64 as the base point. During the process, the curved spring plate 62 and the C-shaped spring plate 65 are squeezed to deform the curved spring plate 62 and the C-shaped spring plate 65. At the same time, the resilience of the curved spring plate 62 and the C-shaped spring plate 65 makes the sandpaper 68 always fit the inner wall of the pipe.

[0043] When the pipeline passes between the rolling wheel 817 and the flip wheel 826, the rolling wheel 817 and the flip wheel 826 will be forced to move outward, which will in turn cause the vertical rod 816, the third motor 815 and the mounting plate 814 to be subjected to force, and the side wing plate 824 and the second C-shaped side plate 823 to be subjected to force, further causing the first convex sliding block 812 to slide in the first convex sliding groove 811, and the second convex sliding block 822 to slide in the second convex sliding groove 821, further causing the first multi-fold elastic plate 819 and the second multi-fold elastic plate 820 to be squeezed and deformed, and at the same time, the resilience of the first multi-fold elastic plate 819 and the second multi-fold elastic plate 820 will also make the rolling wheel 817 and the flip wheel 826 fit the pipeline.

[0044] Then the third motor 815 and the fourth motor 828 start working, and the output shaft of the third motor 815 drives the vertical rod 816 to rotate through the coupling, which in turn causes the rolling wheel 817 to rotate, and the output shaft of the fourth motor 828 drives the pulley 825 to rotate. Under the action of the tensioned belt, a pair of pulleys 825 will rotate at the same time, and further the rotating rod will drive the flip wheel 826 to rotate. The rotation of the rolling wheel 817 will move the pipeline, and the rotation of the flip wheel 826 will rotate the pipeline. The sandpaper 68 will grind the surface of the pipeline in all directions.

[0045] When cutting is to be performed, the third motor 815 and the fourth motor 828 are stopped first, and the second motor 583 is started again to make it work, so that its output shaft will drive the bidirectional screw 582 to rotate again, and then the nut 584 will be driven (this is the prior art and is not described in detail in this application document), and further a pair of first C-shaped clamping plates 51 will be close to each other with the cooperation of the convex slide rail 57 and the slide groove, and further the second C-shaped clamping plate 53 and the grinding unit 6 will move together, so that the C-shaped pressure plate 63 will be further squeezed, and the curved spring plate 62 and the C-shaped spring plate 65 will be further deformed, so that the sandpaper 68 will conflict with the pipe, and then the second motor 583 will be stopped, so that the pipe is fixed.

[0046] When the cutting is completed, the pipe is released and the third motor 815 and the fourth motor 828 are started. The pipe will continue to rotate and move. When the pipe cut passes through a pair of first C-shaped clamping plates 51 at the other end, the sandpaper 68 will grind the outer wall of the pipe cut.

[0047] If the sandpaper 68 needs to be replaced, the pressure plate is turned over to make the limiting sleeve rotate so that it does not conflict with the sandpaper 68, and then the sandpaper 68 is taken down for replacement, and then the new sandpaper 68 is passed through the second waist-shaped hole 67 and between the limiting sleeve and the weakened groove 64, and then the pressure plate is turned over to return to its original position, which will fix the sandpaper 68 again.

[0048] During use, when the pipe moves to the supporting cross plate 97, the bottom of the pipe will be located in the arc-shaped supporting groove 99. When adjusting the cutting position of the pipe, the cutting position will always be located in the C-shaped bent plate 98. The waste foam and iron filings generated during cutting will slide to the intersection of the C-shaped bent plate 98 and the arc-shaped supporting groove 99 for collection, and enter the discharge pipe through the discharge hole 910. When the tool in the cutting unit 2 is overheated, the coolant is allowed to enter the injection pipe through an external water supply device, and then the water injection pipe will inject it into the water spray pipe 96. The tool will come into contact with the coolant during the cutting process, which will then cool the tool, and the waste liquid will enter the discharge hole 910. If the discharge pipe is blocked, excess waste foam and iron filings will overflow through the discharge hole 95 mixed with the waste liquid.
