Description

Technical Field

[0001] The present invention relates to the technical field of power pipe cutting, and in particular to a power pipe cutting device and method for power construction. Background Art

[0002] As a vital basic material in power engineering, the performance of power pipes is directly related to the safety and stability of the power system. At present, power pipes are usually hot-dip plasticized with PE (modified polyethylene) or coated inside and outside with epoxy resin. The selection of these materials and the coating process give power pipes excellent corrosion resistance, which enables them to effectively resist the erosion of chemical substances when buried underground for a long time or exposed to various complex environments, ensuring their long-term use under harsh conditions. During the power construction process, the construction site is often complex and changeable, and the processing requirements of power pipes have also become diversified. In order to ensure that the power pipes can adapt to different construction scenarios, they need to be precisely cut and processed.

[0003] The existing Chinese patent with publication number CN113814463A includes a placement plate, a placement frame, and a cutting mechanism. The placement frame is installed below the placement plate. A through slot is opened on the placement plate. The cutting mechanism is installed above the through slot and on one side of the end of the placement plate. The cutting mechanism includes a U-shaped frame, a telescopic rod, a second motor, and a cutting tool. The telescopic rod is installed below the top of the U-shaped frame, the second motor is installed at the end of the movable end of the telescopic rod, and the cutting tool is installed on the second motor. A conveying mechanism is installed on one side of the cutting mechanism and on the placement plate.

[0004] When the above device is in use, the transmission mechanism can transport the power pipe the same distance each time, thereby ensuring the same length of each cut, avoiding secondary cutting, and improving work efficiency. The power pipe is automatically fixed and cut by the fixing mechanism and the cutting mechanism, reducing manual operation of personnel and ensuring safety at work. However, in actual use, due to the large diameter of the power pipe, it is difficult to cut it in one go, and personnel are required to rotate the power pipe for multiple cuts, which is time-consuming and labor-intensive, and can easily cause an uneven cross-section of the power pipe. Therefore, it is difficult to automatically adjust the power pipe for rotation during the cutting process.

[0005] To this end, we propose an electric pipe cutting device and method for electric power construction. Summary of the invention

[0015] Preferably, a method for cutting a power pipe for power construction comprises the following steps: S1. Clamping operation: firstly, place the power tube on the inner wall of the support tube. When the limit block moves toward the limit position of the parallelogram groove close to one end of the crank, the limit block pulls the slide bar to reset in the upward vertical direction under the action of the oblique groove on the side of the parallelogram groove close to the crank. At this time, the first gear ring drives the turntable to rotate in the direction of C under the action of the first tooth plate, and then the slider pulls the L-shaped block and the arc block to retract and move under the action of the arc through groove, so that the arc block contacts the arc surface of the power tube and clamps and fixes it. S2. Moving the power pipe: When the connecting rod pushes the U-shaped frame to move horizontally toward one end close to the positioning cylinder, and the sliding rod pushes the limit block to move synchronously along the horizontal groove on the top side of the parallelogram groove under the action of the U-shaped frame, the U-shaped frame can drive the power pipe on the inner wall of the support cylinder to move horizontally toward one end of the positioning cylinder; S3, cutting operation: when the rectangular sleeve drives the limit block to move along the horizontal groove at the top of the parallelogram groove to a position close to one end of the positioning cylinder, and one end of the inclined surface of the inclined plate moves to the inner wall of the rectangular through groove, the second tooth plate can drive the connecting plate to move horizontally toward the direction close to the T-shaped block under the action of the inclined plate, so that the columnar rod pushes the moving block to the extreme position of the support groove close to one end of the positioning cylinder under the support of the first spring, and at this time, the cutting blade contacts one side of the power tube and performs the cutting operation; S4. Rotating the electric tube: as the limit block moves along the inclined surface of the parallelogram groove close to one side of the positioning tube, the second tooth plate continues to move in the horizontal direction close to the second tooth ring under the action of the inclined plate, so that the second tooth ring drives the positioning tube to rotate on the fixed plate under the action of the second tooth plate, and the anti-slip pad that increases the friction is set inside the positioning tube, so that the positioning tube can drive the electric tube on the inner wall to rotate synchronously on a fixed axis, and then the cutting blade can perform circular cutting along the outer side of the electric tube.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The crank is driven by a motor to rotate on the n-shaped frame with a fixed axis, so that the connecting rod can push the U-shaped frame and the rectangular sleeve to move horizontally back and forth on the outer contour of the n-shaped frame. When the connecting rod pulls the U-shaped frame to move horizontally toward the end away from the positioning cylinder, the limit block moves toward the extreme position of the parallelogram groove close to one end of the crank, so that the limit block pulls the slide bar in the upward vertical direction to reset under the action of the inclined groove on the side of the parallelogram groove close to the crank. At the same time, the first gear ring drives the turntable to rotate in the C direction under the action of the first tooth plate, and then the slider pulls the L-shaped block and the arc block to retract under the action of the arc through groove, so that the arc block contacts the arc surface of the power tube and is clamped and fixed.

[0017] 2. When the connecting rod pushes the U-shaped frame to move horizontally toward one end close to the positioning cylinder, and the sliding rod pushes the limit block to move synchronously along the horizontal groove on the top side of the parallelogram groove under the action of the U-shaped frame, accompanied by the arc block contacting and clamping the arc surface of the power tube, the U-shaped frame can drive the power tube on the inner wall of the support tube to move in the horizontal direction close to one end of the positioning cylinder.

[0018] 3. When the rectangular sleeve drives the limit block to move along the horizontal groove at the top of the parallelogram groove to a position close to one end of the positioning cylinder, and one end of the inclined surface of the inclined plate moves to the inner wall of the rectangular through groove, the second tooth plate can drive the connecting plate to move horizontally toward the direction close to the T-shaped block under the action of the inclined plate, so that the columnar rod pushes the moving block to the extreme position of the support groove close to one end of the positioning cylinder under the support of the first spring. At this time, the cutting blade contacts one side of the power pipe and performs the cutting operation.

[0019] 4. As the limit block moves along the inclined surface of the parallelogram groove close to one side of the positioning cylinder, the second tooth plate continues to move in the horizontal direction close to the second tooth ring under the action of the inclined plate, so that the second tooth ring drives the positioning cylinder to rotate on the fixed plate under the action of the second tooth plate. With the anti-slip pad that increases the friction force arranged inside the positioning cylinder, the positioning cylinder can drive the electric power pipe on the inner wall to rotate synchronously on a fixed axis, and then the cutting blade can perform circular cutting along the outer side of the electric power pipe, thereby improving the cutting efficiency of the electric power pipe.

[0020] The coordinated use of the above-mentioned structure solves the problem that in actual use of the existing device, due to the large diameter of the power pipe, it is difficult to cut it in one go, and personnel need to rotate the power pipe for multiple cuts, which is time-consuming and labor-intensive, and easily causes the cross-section of the power pipe to be uneven. Therefore, it is difficult to automatically adjust the power pipe for rotation during the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] When in use, the second toothed ring 30 is matched with the teeth on the second toothed plate 24 through the second toothed ring 30 set on the positioning cylinder 20. When the rectangular sleeve 3 drives the limit block 17 to move along the top horizontal groove of the parallelogram groove 181 to a position close to one end of the positioning cylinder 20, and the cutting blade 23 moves to one side of the power tube for cutting, the second toothed plate 24 moves to engage with the teeth on the second toothed ring 30.

When the limit block 17 moves toward the limit position of the parallelogram groove 181 close to one end of the crank 6, the limit block 17 pulls the slide bar 15 to reset in the upward vertical direction under the action of the oblique groove on the side of the parallelogram groove 181 close to the crank 6.

Rotating the electric tube: as the limit block 17 moves along the parallelogram groove 181 close to the inclined surface on one side of the positioning tube 20, the second tooth plate 24 continues to move in the horizontal direction close to the second tooth ring 30 under the action of the inclined plate 29, so that the second tooth ring 30 drives the positioning tube 20 to rotate on the fixed plate 19 under the action of the second tooth plate 24. With the anti-slip pad that increases the friction force set inside the positioning tube 20, the positioning tube 20 can drive the electric tube on the inner wall to rotate synchronously, and then the cutting blade 23 can perform circular cutting along the outer side of the electric tube.
