Description

Technical Field

[0001] This disclosure belongs to the field of power engineering technology, and specifically relates to a pipeline cutting device. Background Technology

[0002] As a bridge for power transmission, the importance of cables is self-evident. During cable laying, some cables need to be placed underground, requiring them to be threaded through conduits, which then protect the cables. The length of the conduits used must be flexibly determined based on the length of the cables being laid. On the construction site, conduits need to be cut to ensure the required length meets practical needs.

[0003] In related technologies, pipeline cutting is mostly performed using a cutting machine. A cutting machine includes a frame and a cutting blade movably connected to the frame. The cutting blade can move in a direction perpendicular to the pipeline's axis. During cutting, the pipeline is first laid flat on the ground, and then the cutting machine is controlled to move the cutting blade towards the pipeline.

[0004] However, since the construction environment is generally outdoors, operators may not be able to find a perfectly flat surface to place the pipelines on the construction site, which can cause the pipelines to wobble during cutting and affect the cutting accuracy. Summary of the Invention

[0010] In another implementation of this disclosure, the clamping arm further includes an insert block, a positioning block, and a pad block. The insert block and the positioning block are spaced apart within the arm body and located on one side of the elastic rope within the threading hole. Both the insert block and the positioning block are connected to the second end of the slide rod. The pad block is located within the arm body and on the other side of the elastic rope within the threading hole. The pad block is connected to the arm body and has a positioning hole. The insert block is used to be inserted between the pad block and the arm body, and the positioning block is used to be inserted into the positioning hole.

[0011] In another implementation of this disclosure, the clamping assembly further includes multiple pairs of cable storage boxes, each pair of cable storage boxes being arranged correspondingly to at least one elastic rope, and two cable storage boxes in each pair being connected one-to-one to the two clamping arms connected to the corresponding elastic rope; the two ends of the elastic rope pass through the wire holes of the two clamping arms and are located in the corresponding pair of cable storage boxes.

[0012] In another implementation of this disclosure, the clamping assembly further includes a clamping mechanism, which is arranged in the same direction as the plurality of clamping rings and located at the same end of the axial direction of the plurality of clamping rings; the clamping mechanism includes two clamping units, which are arranged symmetrically and at intervals, and the extension direction of the axis of symmetry of the two clamping units is the arrangement direction of the plurality of clamping rings; each of the two clamping units includes a clamping drive and a clamping block, the clamping drive being connected to the bracket; the clamping block being connected to the clamping drive, the clamping drive being used to drive the connected clamping block to move, so that the two clamping blocks in the two clamping units move closer to each other.

[0029] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0030] This disclosure provides a pipeline cutting device, such as... Figure 1 As shown, the pipeline cutting device includes a support 1, a cutting assembly 2, and a clamping assembly 3. The clamping assembly 3 includes multiple clamping drive components 31 and multiple clamping rings 32, with each clamping drive component 31 corresponding to one of the clamping rings 32.

[0031] Each of the multiple clamping drive components 31 is connected to the top of the bracket 1. Multiple clamping rings 32 are arranged at intervals along a first direction. Each clamping ring 32 includes multiple elastic ropes 321, which are arranged at intervals along the direction of the clamping rings 32. Each elastic rope 321 has two ends connected to the corresponding clamping drive component 31. The clamping drive component 31 drives each elastic rope 321 in the corresponding clamping ring 32 to clamp the pipeline to be cut. The first direction is the axial direction of the clamping ring 32. The cutting assembly 2 is connected to the bracket 1, and the cutting component of the cutting assembly 2 can move along the cutting path, which passes through the pipeline.

[0032] When the pipeline cutting device provided in this embodiment cuts a pipeline, since the pipeline cutting device includes a support 1, the pipeline cutting device can be supported on the ground by the support 1, and it can also provide an installation base for other components. Furthermore, since the cutting component 2 is located inside the support 1, and the cutting part of the cutting component 2 can move along the cutting path that passes through the pipeline, the pipeline can be cut by the cutting component 2.

[0033] Furthermore, since the pipeline cutting device also includes a clamping assembly 3, and the clamping assembly 3 includes multiple clamping drive members 31 and multiple clamping rings 32, each clamping ring 32 includes multiple elastic ropes 321. The clamping drive members 31 can drive each elastic rope 321 in the corresponding clamping ring 32 to clamp the pipeline to be cut. In this way, during cutting, the pipeline can be pre-positioned in the clamping ring 32 formed by multiple elastic ropes 321, and then the clamping drive members 31 can be controlled to drive the corresponding elastic ropes 321 to clamp the pipeline so as to clamp and fix the pipeline. Finally, the pipeline can be cut by the cutting assembly 2.

[0034] As can be seen, the pipeline cutting device provided in this embodiment can clamp and fix the pipeline through the clamping component 3, thus preventing pipeline swaying and improving cutting accuracy. Furthermore, the use of elastic rope 321 to form the clamping ring 32 not only allows for free control of the size of the clamping ring 32 to match various pipeline specifications, but also, through the elasticity of the elastic rope 321, provides a certain buffering effect when clamping the pipeline, preventing excessive clamping force and damage to the pipeline's surface.

[0035] In this embodiment, the pipeline includes a power conduit. The power conduit is made of PE (Polyethylene, modified polyethylene). The power conduit has excellent corrosion resistance. The exterior of the power conduit has a coating, which provides good electrical insulation, prevents electrolytic corrosion, and offers advantages such as low water absorption, high mechanical strength, and a low coefficient of friction. The power conduit effectively prevents damage from plant roots and soil stress. During cable laying, some cables need to be placed underground; in this case, the power conduit can protect the cables, allowing them to be threaded within it.

[0036] In other examples, pipelines also include other structures, such as cables.

[0037] Optionally, the cutting assembly 2 includes a cutting lifting frame 21, multiple guide wheels 22, and a wire saw 23. The cutting lifting frame 21 is connected to the inner top of the support 1 and is movable along the direction from the top to the bottom of the support 1. Each of the multiple guide wheels 22 is rotatably connected to the cutting lifting frame 21. The multiple guide wheels 22 are spaced apart and form a planar geometric shape, and along the lifting direction of the cutting lifting frame 21, the straight line containing the bottom edge of the planar geometric shape is perpendicular to the lifting direction of the cutting lifting frame 21. The wire saw 23 is fitted around the guide wheels 22 and is movable while the guide wheels 22 are rotating.

[0038] Figure 2 for Figure 1 A sectional view along the BB direction, combined with Figure 2 , combined Figure 2The cutting assembly 2 also includes a cutting motor 24. The cutting motor 24 is connected to the cutting lifting frame 21 and to one of the plurality of guide wheels 22, for driving the connected guide wheel 22 to rotate.

[0039] In the above implementation, the cutting motor 24 is started, which drives one of the guide wheels 22 to rotate, thereby driving the wire saw 23 to move, thus enabling the pipeline to be cut.

[0040] See you again Figure 1 and Figure 2 In this embodiment, the planar geometric shape formed by the arrangement of multiple guide wheels 22 can be flexibly arranged according to the number of guide wheels 22. For example, when there are three guide wheels 22, the planar geometric shape can be a triangle. When there are four guide wheels 22, the planar geometric shape can be a quadrilateral or a triangle. If it is a quadrilateral, then along the lifting direction of the cutting lifting frame 21 (i.e., Figure 2 In the vertical direction), the two guide wheels 22 located below are at the same height, and the straight line they are on (that is, in the vertical direction) is the same. Figure 2 The horizontal direction of the cutting lifting frame 21 is perpendicular to the lifting direction of the cutting lifting frame 21. The other two guide wheels 22 are located at any position above, either at the same height or not. If the planar geometry formed by the four guide wheels 22 is a triangle, then three of the guide wheels 22 are located at the bottom, at the same height, and on the same straight line (i.e., the horizontal direction of the cutting lifting frame 21). Figure 2 The horizontal direction of the cutting lifting frame 21 is perpendicular to the lifting direction of the cutting lifting frame 21. The other one is located above.

[0041] In other words, the number of guide wheels 22 and the resulting planar geometry can be set arbitrarily, as long as at least one section of the cutting wire saw 23 is perpendicular to the lifting direction of the cutting lifting frame 21.

[0042] In this embodiment, there are three guide wheels 22. The three guide wheels 22 simplify the structure of the cutting assembly 2, allowing the wire saw 23 to move along the plane geometry formed by the three guide wheels 22, which is a triangle. The cutting lifting frame 21 includes a tripod 211 and a lifting drive 212. Each corner of the tripod 211 is equipped with a rotatable guide wheel 22. The output end of the cutting motor 24 is fixedly connected to the side wall of the uppermost guide wheel 22. The lifting drive 212 is located between the top of the tripod 211 and the inner top of the support 1, and is connected to both the support 1 and the top of the tripod 211. The lifting drive 212 drives the tripod 211 to move along the top to the bottom of the support 1. Thus, the tripod 211 can be raised and lowered by the lifting drive 212.

[0043] In this embodiment, the lifting drive component 212 includes two electrically operated telescopic rods, which are connected at intervals to the top of the tripod 211. The two electrically operated telescopic rods are parallel to each other and connected to the uniform support 1.

[0044] During cutting, the electric telescopic rod is activated, causing the tripod 211 to descend, thereby cutting the conduit.

[0045] See you again Figure 1 Optionally, the bracket 1 includes four support rods 11 ( Figure 1 (Only two of them are shown), two connecting rods 12, a middle rod 13, and a rotating cylinder 14. Four support rods 11 are parallel to each other and located at the four vertices of the rectangle. The two connecting rods 12 are parallel to each other and perpendicular to the four support rods 11. Each connecting rod 12 has its two ends connected to the two support rods 11. The middle rod 13 is located between the two connecting rods 12. The middle rod 13 is perpendicularly connected to the two connecting rods 12. The rotating cylinder 14 is fitted over the middle rod 13 and is rotatably connected to it. The rotating cylinder 14 is located between the two connecting rods 12, and the top of the tripod 211 is connected to the rotating cylinder 14.

[0046] The support rod 11 is used to support the connecting rod 12 and the intermediate rod 13. The connecting rod 12 is used to connect the support rods 11 together. The intermediate rod 13 is used to provide a mounting base for the rotating cylinder 14. The rotating cylinder 14 is used to rotate relative to the intermediate rod 13 so that it rotates synchronously with the tripod 211, so that the cutting surface of the wire saw 23 can be perpendicular to the axis of the pipeline, so that the cut end face is always flat, thereby improving cutting accuracy.

[0047] In this embodiment, to facilitate the connection between the tripod 211 and the rotating cylinder 14, the bracket 1 further includes a U-shaped connecting frame 15. The connecting frame 15 has an opening facing the tripod 211, so that part of the tripod 211 is located inside the connecting frame 15. The side wall of the connecting frame 15 opposite to the opening is connected to the rotating cylinder 14 and to the lifting drive component. The opposite side walls of the connecting frame 15 forming the opening are respectively connected to the two clamping arms 311 (described below) of the same clamping drive component 31.

[0048] In this embodiment, there are two clamping drive components 31 and two clamping rings 32.

[0049] Figure 3 for Figure 1 A side view of the connection between the clamping drive and the clamping ring, combined with... Figure 3Optionally, the clamping ring 32 further includes a plurality of arc-shaped sliding blocks 322, which are arranged at intervals along the circumference of the elastic rope 321. In the same clamping ring 32, each of the plurality of sliding blocks 322 is simultaneously fitted over each elastic rope 321, and each sliding block 322 is connected to each elastic rope 321.

[0050] In the above implementation, the arrangement of multiple sliding blocks 322 can effectively increase the contact area between the clamping ring 32 and the outer surface of the pipeline, thereby increasing the clamping effect.

[0051] In this embodiment, the sliding block 322 has multiple sliding grooves, and the multiple sliding grooves correspond one-to-one with the multiple elastic ropes 321 in the same clamping ring 32. Each elastic rope 321 is embedded in the corresponding sliding groove.

[0052] See you again Figure 1 Optionally, the clamping drive 31 includes two clamping arms 311 and two drive members 312. The two clamping arms 311 are hinged together at the middle and are symmetrically distributed about the hinge axis of the two clamping arms 311. The direction of the hinge axis of the two clamping arms 311 is the arrangement direction of the multiple clamping rings 32. The first end of each clamping arm 311 is connected to each elastic rope 321 in the clamping ring 32 corresponding to the clamping drive 31.

[0053] Two drive members 312 are respectively connected to the bracket 1, and each of the two drive members 312 is connected to the second end of the corresponding clamping arm 311 to drive the clamping arm 311 to rotate.

[0054] In the above implementation, the driving component 312 is used to drive the clamping arm 311 to rotate. When the clamping arm 311 rotates about the hinge axis of the two clamping arms 311, it can tighten or loosen the elastic rope 321 connected to the clamping arm 311, thereby achieving clamping of the pipeline.

[0055] In actual use, the pipeline cutting device is moved above the pipeline, and then the pipeline is inserted into the clamping ring 32. The drive unit 312 is controlled to drive the clamping arm 311 to rotate. The clamping arm 311 is hinged to make the elastic rope 321 clamp the pipeline, and then the cutting assembly 2 can be controlled to cut the pipeline.

[0056] In this embodiment, the driving member 312 is an electric telescopic rod. The fixed end of the driving member 312 is connected to the bracket 1, and the telescopic end of the driving member 312 is connected to the second end of the corresponding clamping arm 311. The telescopic direction of the driving member 312 is perpendicular to the hinge axis of the two clamping arms 311.

[0057] In this way, the drive unit 312 is activated, and the drive unit 312 extends, using the hinge to make the elastic rope 321 clamp the pipeline in order to fix the pipeline.

[0058] In other examples, the drive element 312 can also be other structures, such as a hydraulic cylinder. The piston rod of the hydraulic cylinder is connected to the clamping arm 311.

[0059] Figure 4 for Figure 1 Enlarged view of point A in the middle, combined with Figure 4 Optionally, the clamping arm 311 includes an arm body 3111 and a slide bar 3112. The first end of the arm body 3111 near the elastic cord 321 has a threading hole 3110 for the elastic cord 321 to pass through.

[0060] The first end of the slide bar 3112 is located outside the arm body 3111, and the second end of the slide bar 3112 is slidably located inside the first end of the arm body 3111 near the elastic rope 321. The slide bar 3112 can move relative to the arm body 3111 along the length direction of the arm body 3111 to clamp the elastic rope 321 in the thread hole 3110.

[0061] In the above implementation, the slide bar 3112 is used to move in the arm body 3111 so as to clamp the elastic rope 321 in the thread hole 3110.

[0062] In this embodiment, the slide rod 3112 is a screw rod, and the slide rod 3112 is threadedly connected to the arm body 3111. This allows the length of the slide rod 3112 extending into the arm body 3111 to be adjusted at any time, so as to adjust the inner diameter of the clamping ring 32 formed by the elastic rope 321 at any time.

[0063] Optionally, the clamping arm 311 further includes an insert block 3114, a positioning block 3116, and a pad block 3117. The insert block 3114 and the positioning block 3116 are spaced apart within the arm body 3111 and located on one side of the elastic rope 321 within the threading hole 3110. Both the insert block 3114 and the positioning block 3116 are connected to the second end of the slide bar 3112. The pad block 3117 is located within the arm body 3111 and on the other side of the elastic rope 321 within the threading hole 3110. The pad block 3117 is connected to the arm body 3111 and has a positioning hole 3001 communicating with the threading hole 3110. The insert block 3114 is used to insert between the pad block 3117 and the arm body 3111, and the positioning block 3116 is used to insert into the positioning hole 3001.

[0064] This allows the length of the elastic rope 321 to be adjusted according to the diameter of different pipelines. After adjustment, the corresponding slide bar 3112 is rotated, causing the slide bar 3112 to move within the arm body 3111, and the elastic rope 321 can then be clamped by the insert block 3114 and the pad block 3117.

[0065] In this embodiment, to facilitate the arrangement of the insert block 3114, positioning block 3116, etc., the arm body 3111 has a clamping groove 3002 at one end near the elastic rope 321, and the clamping groove 3002 communicates with the threading hole 3110. The threading hole 3110 divides the clamping groove 3002 into two parts. The insert block 3114 and the positioning block 3116 are both located in the first part of the clamping groove 3002, at the first end of the threading hole 3110 facing the arm body 3111, and the pad block 3117 is located in the second part of the clamping groove 3002.

[0066] To improve the clamping effect, there are two insertion blocks 3114, and the positioning block 3116 is located between the two insertion blocks 3114.

[0067] For example, in order to facilitate the connection between the slide rod 3112 and the positioning block 3116, the second end of the slide rod 3112 has a moving block 3113. The moving block 3113 is connected to the second end of the slide rod 3112 by fasteners (such as fastener positioning bolts). The two insert blocks 3114 and the positioning block 3116 are all connected to the side of the moving block 3113 away from the slide rod 3112 by fasteners (such as fastener positioning bolts).

[0068] In this embodiment, the end of the arm body 3111 near the elastic rope 321 may have one or more threading holes 3110. If there is only one threading hole 3110, multiple elastic ropes 321 in the same clamping ring 32 are located together in the threading hole 3110.

[0069] In other examples, there may be multiple threading holes 3110. If there are multiple threading holes 3110, the multiple elastic ropes 321 in the same clamping ring 32 correspond one-to-one with the multiple elastic ropes 321. At this time, the insert block 3114, the positioning block 3116, and the pad block 3117 are all in contact with the multiple elastic ropes 321 in the multiple threading holes 3110.

[0070] See you again Figure 1 Optionally, the clamping assembly 3 also includes multiple pairs of cable storage boxes 33, each pair of cable storage boxes 33 being connected to at least one elastic cord 321. Two cable storage boxes 33 in each pair are respectively connected one-to-one to two clamping arms 311 connected to the elastic cord 321. The two ends of the elastic cord 321 pass through the wire holes 3110 of the two clamping arms 311 and are located within the corresponding pair of cable storage boxes 33.

[0071] In the above implementation, the cable storage box 33 is used to store the excess elastic rope 321 so that the length of the elastic rope 321 forming the clamping loop 32 can be adjusted at any time.

[0072] In other examples, the cable storage box 33 may also be other structures, such as a reel, with the end of the elastic cord wound around the reel.

[0073] In this embodiment, a cable storage box 33 can store one end of multiple elastic ropes 321 in the same clamping ring 32 together, or a cable storage box 33 can store only one end of one elastic rope 321 in the same clamping ring 32.

[0074] Optionally, the clamping assembly 3 further includes a clamping mechanism 34, which is arranged in the same direction as the plurality of clamping rings 32 and located at the same end in the axial direction of the plurality of clamping rings 32.

[0075] The clamping mechanism 34 includes two clamping units arranged symmetrically and at intervals, with the axis of symmetry of the two clamping units pointing in the direction of the arrangement of the plurality of clamping rings 32. Each clamping unit includes a clamping drive 341 and a clamping block 342. The clamping drive 341 is connected to the bracket 1. The clamping block 342 is connected to the clamping drive 341, and the clamping drive 341 is used to drive the connected clamping block 342 to move, so that the two clamping blocks 342 in the two clamping units move closer to each other.

[0076] In the above implementation, the clamping drive 341 is used to drive the clamping block 342 to move, so as to simply lock the pipeline. That is, when the pipeline is inserted into the clamping assembly 3, it can be pre-positioned by the clamping block 342, so that the pipeline can be initially fixed.

[0077] In this embodiment, the clamping drive 341 is a screw, and its middle part is threadedly connected to the bracket 1. The clamping block 342 is connected to the end of the clamping drive 341 facing the clamping ring 32 by welding or fasteners. Thus, by rotating the clamping drive 341, it can move toward or away from the bracket 1, thereby causing the clamping block 342 to move.

[0078] Figure 5 for Figure 1 Side view of the clamping mechanism, combined with Figure 5Optionally, the clamping unit further includes a fixing plate 340, a cylinder 343, a slide rod 344, an arc-shaped plate 345, and an elastic element 346. The fixing plate 340 is connected to the side of the clamping block 342 facing the arc-shaped plate 345, and the first end of the cylinder 343 is connected to the fixing plate 340. The length direction of the cylinder 343 is perpendicular to the arrangement direction of the plurality of clamping rings 32. The first end of the slide rod 344 is located inside the cylinder 343, and its middle part is slidably located in the fixing plate 340. The second end of the slide rod 344 is located outside the cylinder 343 and is connected to the arc-shaped plate 345. The inner arc surface of the arc-shaped plate 345 is used to fit against the outer wall of the pipeline. The elastic element 346 is located inside the cylinder 343, and its two ends are clamped between the first end of the slide rod 344 and the cylinder 343.

[0079] In the above implementation, the structure enables the pipeline to be easily locked by the elastic force of the elastic element 346 when it is inserted into the clamping assembly 3, thereby ensuring smooth insertion.

[0080] In this embodiment, the clamping block 342 is a rectangular block structure. This allows for initial positioning of the components.

[0081] Optionally, the clamping unit also includes a guide plate 347, which is connected to the side of the arc plate 345 away from the clamping block 342, and the distance between the two guide plates 347 gradually decreases along the direction from the guide plate 347 to the arc plate 345 to which it is connected.

[0082] To ensure smooth insertion of the pipeline, two inclined guide plates 347 serve as a guide.

[0083] Optionally, the clamping unit also includes a plurality of balls 348, which are spaced apart and embedded in the inner arc surface of the arc plate 345. The balls 348 can reduce friction between the pipeline and the arc plate 345, facilitating pipeline insertion.

[0084] The following is a brief description of the working process of the pipeline cutting device provided in this embodiment:

[0085] When cutting the pipeline, the pipeline cutting device is moved above the pipeline, and the pipeline is inserted into the two clamping rings 32 formed by the two sets of elastic ropes 321.

[0086] At the same time, rotating the slide bar causes the moving block 3113 to move within the arm body 3111, which places the elastic rope 321 between the two insert blocks 3114 and the pad block 3117, clamping and fixing the elastic rope 321, effectively increasing the contact area and ensuring the locking effect.

[0087] Start the drive unit 312. Since the clamping arms 311 are hinged in pairs, the drive unit 312 extends and drives the clamping arms 311 to rotate. After the clamping arms 311 rotate, the elastic rope 321 clamps the pipeline. Then, start the lifting drive unit 212 to lower the tripod 211.

[0088] During the cutting process, the cutting motor 24 is started, which drives one of the guide wheels 22 to rotate, thereby driving the wire saw 23 to rotate, thus cutting the pipeline.

[0089] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
