Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power pipe cutting, in particular to a power pipe cutting device and method based on power construction. BACKGROUND

[0002] At present, in the process of power engineering construction, the power pipe as the core component of cable protection needs to be cut into different lengths according to the construction scene demand, and the cutting quality directly affects the safety and stability of subsequent cable laying. The power pipe cutting device used in the current power construction gradually exposes many technical defects in actual application, and it is difficult to meet the efficient, accurate and convenient construction demand.

[0003] Among them, the diameter specifications of the power pipe commonly used in power construction are various (such as 50mm, 110mm, 160mm, etc.), and the cutting mechanism position of the existing cutting device is mostly fixed or needs to be manually adjusted. When manually adjusting, the power pipe diameter needs to be measured first, and then the cutting assembly is manually moved to the adaptive position through bolts, guide rails and other structures. Not only is the operation cumbersome and time-consuming, but also the cutting mechanism and the center of the power pipe are deviated due to the manual measurement error and uneven adjustment force, which causes problems such as inclined cut and pipe wall deformation. Especially for large diameter power pipes, the difficulty of manual adjustment increases significantly, which seriously affects the construction efficiency and cutting precision. A large amount of plastic or metal waste will be generated during the cutting process of the power pipe, and the existing device generally lacks an efficient waste treatment mechanism. On the one hand, the waste is easy to adhere to the cutting tool and the surface of the power pipe cutout: the plastic waste is easy to stick in the saw blade tooth gap after heating, which increases the cutting resistance of the saw blade and accelerates the wear and tear, not only reduces the cutting efficiency, but also causes rough cut and cracks. The metal waste may scratch the outer wall of the power pipe, damage the anticorrosive layer, and affect the long-term service life of the power pipe. On the other hand, the scattered waste will accumulate on the operation table surface: the waste accumulated on the operation table needs to be cleaned regularly by manual, which increases the workload of the construction personnel.

[0035] Embodiment 1, refer to Figures 1 to 5 , the first embodiment of the present application, the embodiment provides a power pipe cutting device based on power construction, which can realize the cutting effect of power pipes with different diameters, which comprises, The operating table 1 is fixedly installed with the first support 11, the outer ring 12 is rotatably installed in the first support 11, the inner wall of the first support 11 is fixedly connected with the outer shaft of the first bearing, the inner shaft of the first bearing is fixedly connected with the outer wall of the outer ring 12, the inner wall of the outer ring 12 is symmetrically provided with the abutting groove 13, the inner diameter of the abutting groove 13 increases in the clockwise direction, the inner ring 14 is rotatably installed in the outer ring 12, the inner wall of the inner ring 14 is fixedly connected with the outer shaft of the second bearing, the inner shaft of the second bearing is fixedly connected with the outer wall of the inner ring 14, the extrusion cutting mechanism is symmetrically installed on one side of the inner ring 14, and the outer end of the extrusion cutting mechanism abuts against the inner wall of the abutting groove 13; The outer ring 12 rotates through the first driving element, the inner ring 14 rotates through the second driving element, the rotation speed of the outer ring 12 is less than that of the inner ring 14, and the outer end of the extrusion cutting mechanism is used to move along the inner wall of the abutting groove 13 and push the extrusion cutting mechanism to be close to the center of the inner ring 14; The first cleaning assembly is assembled on the inner ring 14 and is used to clean the outer wall of the power pipe along with the inner ring 14; The second cleaning assembly is installed on the operating table 1 and is used to concentrate the waste on the operating table 1; The operating table 1 is provided with the leakage port 36, the baffle 37 is rotatably installed in the leakage port 36, the inner wall of the leakage port 36 is fixedly installed with the bearing on both sides, the inner shaft of the two bearings is fixedly installed with the rotating shaft, the two rotating shafts are fixedly connected with the two sides of the baffle 37 respectively, the baffle 37 is provided with the collecting box 4 at the bottom, the supporting gas conveying mechanism is installed on both sides in the collecting box 4, the supporting gas conveying mechanism receives the gas to be introduced, effectively supports the baffle 37, and the gas is conveyed to the first cleaning assembly and the second cleaning assembly respectively, the supporting gas conveying mechanism stops the gas to be introduced, cannot support the baffle 37, and the baffle 37 automatically tilts by the self-gravity.

[0036] In this embodiment, the device is started, the to-be-cut power pipe is placed in the inner cavity of the inner ring 14, the outer ring 12 and the inner ring 14 start to rotate under the driving of the respective driving members, the cutting mechanism rotates with the inner ring 14 to realize the circumferential cutting of the power pipe, and the first cleaning assembly cleans the outer wall of the power pipe, and the second cleaning assembly processes the waste on the operation table 1, and the waste falls into the collecting box 4 through the material leakage hole 36; the first driving member drives the inner ring 14 to rotate, the second driving member drives the outer ring 12 to rotate, and the rotation speed of the outer ring 12 is set to be less than that of the inner ring 14; because the diameters of the inner wall of the outer ring 12 and the resistance groove 13 increase in the clockwise direction in turn, the inner ring 14 drives the extrusion cutting mechanism to rotate synchronously when rotating, the outer end of the extrusion cutting mechanism continuously contacts the inner wall of the resistance groove 13, and under the action of the speed difference, the outer end of the extrusion cutting mechanism moves along the inner wall of the resistance groove 13 from a smaller diameter to a larger diameter, thereby pushing the extrusion cutting mechanism to the center of the inner ring 14, automatically adapting the cutting position of power pipes of different diameters without manual intervention; when the inner ring 14 rotates, the first cleaning assembly is driven to move synchronously, the first cleaning assembly cleans the outer wall of the power pipe in real time, and removes the waste attached to the pipe wall in the cutting process; the second cleaning assembly continuously operates to concentrate the waste on the surface of the operation table 1 to the direction of the material leakage hole 36; at this time, the support gas conveying mechanism introduces gas to keep the baffle 37 in the material leakage hole 36 in a horizontal state, the concentrated waste falls on the baffle 37 through the material leakage hole 36 to realize temporary storage; when it is necessary to unload, the support gas conveying mechanism stops introducing gas, the baffle 37 loses support and automatically tilts under the action of its own gravity, and the waste falls into the collecting box 4 below to complete collection; after receiving external gas introduction, the support gas conveying mechanism uses part of the gas to support the baffle 37 of the material leakage hole 36 to keep it horizontal to receive the waste; another part of the gas is conveyed to the first cleaning assembly and the second cleaning assembly to provide cleaning power for them; when the gas introduction is stopped, the force supporting the baffle 37 disappears, the baffle 37 automatically tilts to unload, and at the same time, the cleaning assembly also stops supplying gas, realizing linkage control of support and gas supply.

[0037] It is necessary to be additionally explained that the first support 11 is provided with a clamping table on both sides, the clamping table is fixedly installed on the operation table 1, and is used for clamping both sides of the cutting end of the power pipe.

[0038] Specifically, the extrusion cutting mechanism comprises a movable groove 15 symmetrically opened on one side of the inner ring 14, a movable seat 16 rotatably installed in the movable groove 15, a rotating shaft rotatably installed in the movable groove 15 through a bearing, one end of the rotating shaft fixedly connected with the movable seat 16, an installation groove 17 opened on the movable seat 16, a saber saw 18 detachably installed in the installation groove 17, a plurality of installation holes opened on the saber saw 18 and the installation groove 17, a bolt installed in the corresponding two installation holes, a blade of the saber saw 18 facing the center of the inner ring 14, and a resistance block 19 fixedly installed on the outer side of the movable seat 16 and slidably connected with the resistance groove 13.

[0039] In this embodiment, the movable seat 16 of the extrusion cutting mechanism is rotatably installed in the movable groove 15, and the abutting block 19 outside the movable seat 16 is embedded in the abutting groove 13 in the inner wall of the outer ring 12. When the inner ring 14 and the outer ring 12 have a speed difference, the abutting block 19 slides along the inner wall of the abutting groove 13. Due to the change in the diameter of the abutting groove 13, the abutting block 19 pushes the movable seat 16 to rotate around the rotation axis in the movable groove 15, thereby driving the saber saw 18 on the movable seat 16 to adjust the position. The rotation cooperation between the movable seat 16 and the movable groove 15 limits the movement track of the saber saw 18, ensures that the sawing gap of the saber saw 18 always faces the center of the inner ring 14 during the adjustment process, and avoids cutting deviation. The saber saw 18 is detachably installed in the mounting groove 17 of the movable seat 16. When the saw blade is worn or needs to be adapted to different material power pipes, the old saber saw 18 can be removed by loosening the bolts in the mounting groove 17, and after replacing the new adapted saber saw 18, the disassembly can be completed by re-fixing, without the need to disassemble the entire extrusion cutting mechanism, realizing quick replacement.

[0040] Further, a limiting groove 2 is formed in the middle of the movable seat 16, the center of the limiting groove 2 is arranged in line with the axis of the movable seat 16, and the two axes coincide. A limiting column 21 is slidably connected in the limiting groove 2, and the limiting column 21 is fixedly installed on the inner side of the movable groove 15.

[0041] In this embodiment, when the movable seat 16 rotates around the rotation axis under the push of the abutting block 19, the limiting column 21 always slides in the limiting groove 2. The track of the limiting groove 2 matches the rotation track of the movable seat 16, limiting the movable seat 16 to rotate only along the set track, preventing the movable seat 16 from deviating due to vibration or uneven force on the abutting block 19, thereby avoiding position deviation of the saber saw 18 and ensuring cutting accuracy.

[0042] Among them, two movable grooves 15 are connected and provided with an extrusion groove 22 on one side, the center of the extrusion groove 22 is arranged in line with the axis of the movable seat 16, and the two axes coincide. A spring 23 is installed in the extrusion groove 22, and the spring 23 is fixedly installed on the inner wall of the extrusion groove 22 and the outer wall of the movable seat 16 on both sides.

[0043] In this embodiment, when the movable seat 16 rotates under the push of the abutting block 19, the movable seat 16 extrudes the spring 23, the spring 23 elastically deforms, absorbs the vibration generated during the rotation of the movable seat 16, and reduces the shaking of the saber saw 18; when the cutting is completed, the inner ring 14 and the outer ring 12 stop rotating, the pushing force of the abutting block 19 on the movable seat 16 disappears, the spring 23 restores the deformation, pushes the movable seat 16 back to the initial position, and is ready for the next cutting without manual resetting.

[0044] Preferably, the first driving member comprises a through groove arranged on the operation table 1, a protective box 29 fixedly installed in the through groove, a first tooth 24 rotatably installed on one side of the protective box 29, a driven tooth 26 meshingly installed on the first tooth 24, the driven tooth 26 rotatably installed on the side wall of the protective box 29, a third tooth 27 meshingly installed on the transmission tooth, and the third tooth 27 fixedly installed on one side of the inner ring 14. The central shafts of the first tooth 24 and the driven tooth 26 are both fixedly connected with a rotating shaft, and the rotating shafts are both rotatably connected with the side wall of the protective box 29 through bearings.

[0045] In the embodiment, after the motor 291 of the first driving member is started, the transmission shaft is driven to rotate, the first tooth 24 in the protective box 29 is driven to rotate, the first tooth 24 meshes with the driven tooth 26, the driven tooth 26 is driven to rotate, the driven tooth 26 meshes with the third tooth 27, the third tooth 27 is fixed on one side of the inner ring 14, and then the inner ring 14 is driven to rotate. The protective box 29 wraps the transmission gear set of the first tooth 24, the driven tooth 26 and the third tooth 27. The dust and debris generated during construction are blocked by the protective box 29 and cannot enter the gear meshing part, so as to avoid the abrasion of the gears due to impurities.

The protective box 29 is symmetrically provided with a motor 291 on the outer wall. The driving output end of the motor 291 is in transmission connection with a transmission shaft. The two groups of transmission shafts are fixedly connected with the central shafts of the first tooth 24 and the second tooth 25 through the side wall of the protective box 29. The central shaft of the second tooth 25 is fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected with the side wall of the protective box 29 through a bearing.

[0047] In the embodiment, the two groups of motors 291 of the second driving member are respectively installed on the outer wall of the protective box 29. One group of motors 291 drives the first tooth 24 to rotate through the transmission shaft, and then drives the inner ring 14 to rotate. The other group of motors 291 drives the second tooth 25 to rotate through the transmission shaft, the second tooth 25 meshes with the fourth tooth 28 fixed on the side wall of the outer ring 12, and then drives the outer ring 12 to rotate. By respectively adjusting the rotating speeds of the two groups of motors 291, the rotating speeds of the inner ring 14 and the outer ring 12 can be accurately controlled. The design requirement that the rotating speed of the outer ring 12 is less than the rotating speed of the inner ring 14 is easily realized, and the stable movement of the extrusion cutting mechanism along the resistance groove 13 is ensured.
