Description

Technical Field

[0001] The invention relates to the technical field of pipeline cutting, in particular to intelligent metal pipeline cutting equipment. Background Art

[0002] Pipe cutting refers to the process of cutting or slicing a pipe to achieve repair, replacement or reorganization. Various tools and methods can be used for pipe cutting, depending on the pipe material, diameter and environment in which the pipe is located. Common pipe cutting tools include pipe cutting machines, flame cutting equipment, saw blade cutting machines, etc. In actual operation, the most suitable cutting tools and methods can be selected according to specific needs, and ensure that cutting is performed in accordance with standard operating procedures to ensure the quality and safety of pipe cutting. When performing pipeline modification, upgrading or layout changes, it may be necessary to cut from the inside of the pipe due to the influence of the surrounding environment to adapt to the new pipeline layout or connect other equipment. When using the existing in-pipe cutting equipment, the staff will send the equipment into the pipe, then fix the equipment, and then cut it after the fixation is completed. The operation is cumbersome, which greatly affects the efficiency of pipe cutting. In addition, the existing in-pipe cutting device can only be used at a position close to the pipe mouth and cannot enter the deeper part of the pipe for cutting.

[0042] When in use, the driving motor 62 drives the power shaft 64 to rotate, and the rotation of the power shaft 64 drives the reversing gear 2 73 to rotate. The rotation of the reversing gear 2 73 drives the reversing gear 1 72 meshing with it to rotate, and synchronously drives the fixed shaft 71 connected to the reversing gear 1 72 to rotate.

The rotation of the positioning shaft 1 75 drives the connecting block 1 76 to rotate, thereby driving the support rod 4 to rotate, thereby changing the support angle of the installation bin 1.

[0043] When the power shaft 64 rotates, the rotating shaft 85 is driven to rotate through the unfolding pulley 87 and the unfolding belt 88. When the rotating shaft 85 rotates, the unfolding gear 86 arranged thereon is driven to rotate. When the unfolding gear 86 rotates, the inner gear ring 83 engaged with it is driven to rotate. When the inner gear ring 83 rotates, the annular plate 89 arranged thereon is driven to rotate. The rotation of the annular plate 89 drives the second positioning plate 810 arranged thereon to move synchronously. The movement of the second positioning plate 810 drives the second positioning shaft 811 and the linkage gear 813 arranged on the second positioning shaft 811 to move synchronously.

Under the push of the latching tooth 816, the second positioning shaft 811 rotates, and at the same time drives the second connecting block 812 arranged on the second positioning shaft 811 to rotate, and synchronously drives the support rod arranged on the second connecting block 812 to rotate, thereby changing the support angle for the installation bin 1.

[0044] The positioning mechanism 9 includes a driving member 10 arranged on the connecting block 1 76 and the connecting block 2 812, and the driving member 10 is used to provide power for fixing the installation bin 1. A clamping member 11 is provided on the support rod 4, and the installation bin 1 is fixed by the clamping member 11.

The installation warehouse 1 is provided with a fixed block 1014, and one end of the traction rope 1013 is connected to the fixed block 1014.

[0046] The benefit of the drive member 10 is that it can provide power for the movement of the extension rod 113 while controlling the rotation of the support rod 4, which not only saves production costs but also ensures that the support rod 4 can be fixed synchronously when unfolded, thereby improving the stability and reliability of the entire system.

[0047] When the positioning plate 810 moves, the traction rope 1010 and the traction rope 2 1013 drive the winding wheel 109 and the winding wheel 2 1012 to rotate synchronously. When the winding wheel 109 and the winding wheel 2 1012 rotate, the driving shaft 101 and the driving shaft 2 102 are driven to rotate synchronously.

[0049] The advantage of setting the positioning piece 11 is that it can cope with pipes of different specifications, such as rectangular pipes. There is no need to replace equipment when used for cutting circular pipes and rectangular pipes. By adjusting the initial position of the support rod 4, the support rod 4 can support pipes of different specifications after being unfolded.

[0050] The support rod 4 rotates and drives the extension rod 113 threadably connected thereto to move, so that the extension rod 113 extends out of the extension slot 111 . The setting of the limiting rod 112 prevents the extension rod 113 from rotating together with the support rod 4 .

The extension rod 113 moves, driving the rotating block 114 to move, and at the same time driving the pushing groove 121 opened thereon to move. When the pushing groove 121 moves, the pushing rod 122 slides in the pushing groove 121, and then under the push of the pushing rod 122, the rotating block 114 rotates, thereby driving the electric wheel 2 connected to the rotating block 114 to rotate.

[0053] When in use, the driving motor 62 drives the power shaft 64 to rotate, and the rotation of the power shaft 64 drives the reversing gear 2 73 to rotate. The rotation of the reversing gear 2 73 drives the reversing gear 1 72 meshing with it to rotate, and synchronously drives the fixed shaft 71 connected to the reversing gear 1 72 to rotate. When the fixed shaft 71 and the power shaft 64 rotate in opposite directions, the synchronous pulley 2 79 arranged on the multiple positioning shafts 1 75 is driven to rotate through the synchronous pulley 1 78 and the synchronous belt 710. The rotation of the synchronous pulley 2 79 drives the positioning shaft 1 75 to rotate synchronously. The rotation of the positioning shaft 1 75 drives the connecting block 1 76 to rotate, thereby driving the support rod 4 to rotate, thereby changing the support angle of the installation bin 1.

[0054] When the power shaft 64 rotates, the rotating shaft 85 is driven to rotate through the unfolding pulley 87 and the unfolding belt 88. When the rotating shaft 85 rotates, the unfolding gear 86 arranged thereon is driven to rotate. When the unfolding gear 86 rotates, the inner gear ring 83 engaged with it is driven to rotate. When the inner gear ring 83 rotates, the annular plate 89 arranged thereon is driven to rotate. The rotation of the annular plate 89 drives the second positioning plate 810 arranged thereon to move synchronously. The movement of the second positioning plate 810 drives the second positioning shaft 811 and the linkage gear 813 arranged on the second positioning shaft 811 to move synchronously. During the movement of the linkage gear 813, it engages with the latching tooth 816 on the arc plate 815. Under the push of the latching tooth 816, the second positioning shaft 811 rotates, and at the same time drives the second connecting block 812 arranged on the second positioning shaft 811 to rotate, and synchronously drives the support rod arranged on the second connecting block 812 to rotate, thereby changing the support angle for the installation bin 1.

[0055] When the positioning plate 810 moves, the traction rope 1010 and the traction rope 2 1013 drive the winding wheel 109 and the winding wheel 2 1012 to rotate synchronously. When the winding wheel 109 and the winding wheel 2 1012 rotate, the driving shaft 101 and the driving shaft 2 102 are driven to rotate synchronously. When the driving shaft 101 and the driving shaft 2 102 rotate, the transmission gear 103 is driven to rotate. When the transmission gear 103 rotates, the transmission gear 2 104 is driven to rotate. The rotation of the transmission gear 2 104 drives the support rod 4 connected thereto to rotate on the connecting block 1 76 and the connecting block 2 812. The advantage of the setting of the clockwork spring 108 is that the traction rope 1010 and the traction rope 2 1013 can be reeled in when the positioning plate 810 is reset.

[0056] When the support rod 4 rotates, it drives the extension rod 113 threadedly connected to it to move, so that the extension rod 113 extends out from the extension slot 111. The setting of the limit rod 112 prevents the extension rod 113 from rotating with the support rod 4. The extension rod 113 moves, driving the rotating block 114 to move, and at the same time drives the pushing slot 121 opened thereon to move. When the pushing slot 121 moves, the pushing rod 122 slides in the pushing slot 121, and then under the push of the pushing rod 122, the rotating block 114 rotates, thereby driving the electric wheel 2 connected to the rotating block 114 to rotate.

[0057] Embodiment 2:
