Description

Technical Field

[0001] This utility model relates to the field of pipe cutting, and in particular to an MPP power pipe clamping and cutting device. Background Technology

[0002] MPP power pipe is a type of power engineering pipe made primarily of modified polypropylene. It is mainly used for laying and protecting power cables. It has excellent mechanical properties, high compressive strength, and can withstand large external forces, protecting cables from mechanical damage. At the same time, MPP power pipe has strong corrosion resistance, is not easily affected by soil acidity or alkalinity, and has a long service life.

[0003] When using electrical conduits, depending on the actual construction situation, the conduits need to be cut to varying degrees. In the current process of cutting electrical conduits, an arc-shaped support frame is generally used to support the conduit. Then, one cutter holds the conduit to be cut while another cutter uses a cutting tool to cut off the end of the conduit that needs to be cut.

[0004] In actual cutting processes, when the cutting end of the power pipe is long, due to gravity, a bending phenomenon may occur between the cutting end and the remaining end of the pipe. This bending will cause the cutting surface to shift or tilt, thereby affecting the cutting quality and even causing cutting failure. To address this, an MPP power pipe clamping and cutting device is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide an MPP power pipe clamping and cutting device, which can effectively solve the problem that the pipe may bend between the cutting end and the remaining end due to gravity. This bending will cause the cutting surface to shift or tilt, thus affecting the cutting quality and even causing the cutting to fail.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An MPP power pipe clamping and cutting device includes a support base, a cutting frame mounted on the support base, a cutting blade rotatably connected to the cutting frame, a cutting motor fixed on the cutting frame, the output end of the cutting motor passing through the cutting frame and fixedly connected to the cutting blade, a cutting movement mechanism between the cutting frame and the support base, and a symmetrical support mechanism mounted on the support base. The symmetrical support mechanism includes two support rollers symmetrically arranged on the support base, with the two support rollers located on opposite sides of the cutting blade, and a second support roller on one side of each support roller.

[0008] By adopting the above technical solution, both the retained end and the cut end of the power pipe are located on the symmetrical support mechanism. The symmetrical support mechanism clamps and supports the power pipe, thereby improving the stability of the power pipe during cutting and reducing the possibility of bending due to gravity when the end of the power pipe to be cut is long, which could cause the cut surface to deviate or tilt during cutting.

[0009] Furthermore, both ends of the first support roller are rotatably connected to the first support rod, and both ends of the second support roller are rotatably connected to the second support rod. The ends of the two first support rods away from the first support roller are rotatably connected to the support base. The first support rod and the second support rod intersect each other and are rotatably connected in the middle. An adjustment component is provided between the ends of the two second support rods away from the second support roller and the support base. A synchronous movement component is provided on the support base. A pressing component corresponding to the first support roller and the second support roller is provided on the support base.

[0010] By adopting the above technical solution, two sets of support rollers, namely support roller 1 and support roller 2, are used to support the cutting end and the remaining end of the power pipe simultaneously. Then, the pressing component is used to press down on the power pipe, thereby reducing the possibility of the power pipe bending due to gravity when the end to be cut is long, which could cause the cut surface to deviate or tilt during the cutting process.

[0011] Furthermore, the adjustment assembly includes an adjustment block disposed on a support base, an adjustment groove is provided on the support base, the adjustment block is located in the adjustment groove, and sliding blocks are fixed at both ends of the adjustment block. A sliding groove corresponding to the sliding block is provided on the inner wall of the adjustment groove, the sliding block is located in the sliding groove and is slidably connected to the support base, and the ends of the two support rods away from the support rollers are rotatably connected to the adjustment block.

[0012] By adopting the above technical solution, the adjusting block moves within the adjusting groove, causing the adjusting block to drive the second support rod, which in turn rotates on the first support rod. This allows for convenient adjustment of the distance between the first and second support rollers, accommodating power pipes of different sizes.

[0013] Furthermore, the synchronous movement component includes a synchronous block disposed on a support base. The support base has a moving groove, the synchronous block is located in the moving groove and is slidably connected to the support base. Both ends of the synchronous block slide through the support base and are fixedly connected to corresponding sliding blocks on two adjusting blocks. A moving threaded rod is disposed in the moving groove. One end of the moving threaded rod is rotatably connected to the support base. The moving threaded rod passes through the synchronous block and is threadedly connected to the synchronous block.

[0014] By adopting the above technical solution, the synchronizing block moves within the moving groove, allowing the synchronizing block to simultaneously drive two adjusting blocks, thereby facilitating the simultaneous adjustment of the spacing between the two sets of support rollers one and support roller two.

[0015] Furthermore, the pressing assembly includes a support frame fixed on a support base, a pressing block is provided on the support frame, and two symmetrical pressing rollers are rotatably connected to the pressing block.

[0016] By adopting the above technical solution, the two downward pressure rollers on the downward pressure block press down to abut against the power tube, thereby enabling the power tube to be stably supported between support roller one and support roller two.

[0017] Furthermore, a support block is slidably connected to the support frame, and a downward threaded rod is threadedly connected to the support block. The downward threaded rod passes through the support block, and one end of the downward threaded rod is rotatably connected to the downward pressing block. A limit rod is fixed on the downward pressing block, and the limit rod passes through the support block and is slidably connected to the support block.

[0018] By adopting the above technical solution, the support block moves on the support frame, and the support block drives the lower pressure block to move, so that the two lower pressure rollers can be stably pressed against the power pipe according to the position of the power pipe.

[0019] Furthermore, a cover plate is provided on the movable groove, and the cover plate is fixedly connected to the support base.

[0020] By adopting the above technical solution, the moving groove is sealed with a cover plate, allowing the synchronization block to move within the sealed moving groove. This reduces the amount of debris generated during the cutting of the power pipe that enters the moving groove and affects the movement of the synchronization block.

[0021] Furthermore, the cutting moving mechanism includes a movable vertical rod fixed on a support base, a movable horizontal rod slidably connected to the movable vertical rod, a vertical threaded rod rotatably connected to the movable vertical rod, the vertical threaded rod passing through the movable horizontal rod and threadedly connected to the movable horizontal rod, a drive motor one fixed to one end of the movable vertical rod, the output end of the drive motor one passing through the movable vertical rod and fixedly connected to the vertical threaded rod, a transverse threaded rod rotatably connected to the movable horizontal rod, a cutting frame slidably connected to the movable horizontal rod, the transverse threaded rod passing through the cutting frame and threadedly connected to the cutting frame, and a drive motor two fixed to one end of the movable horizontal rod, the output end of the drive motor two passing through the movable horizontal rod and fixedly connected to the transverse threaded rod.

[0022] By adopting the above technical solution, the cutting frame moves along the moving horizontal bar, and the moving horizontal bar moves along the moving vertical bar, which makes it convenient to adjust the position of the cutting blade when cutting power pipes of different diameters.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This utility model improves the stability of the power pipe during cutting by placing it on the support base. First, based on the diameter of the power pipe, a synchronous moving component drives an adjusting component, which in turn drives support roller one and support roller two to adjust the distance between them. Then, the power pipe passes through support roller one and support roller two, and a pressing component presses down against the power pipe. This reduces the possibility of the power pipe bending due to gravity when the end to be cut is long, thus preventing the cut surface from shifting or tilting during cutting.

[0025] 2. This utility model achieves the purpose of conveniently adjusting the position of the cutting blade when cutting power pipes of different diameters by having the horizontal threaded rod drive the cutting frame, which in turn drives the cutting blade to move directly above the power pipe. Then, the drive motor drives the vertical threaded rod, which in turn drives the moving horizontal rod, which moves on the moving vertical rod.

[0035] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0036] The following is in conjunction with the appendix Figure 1 —6 provides further details regarding this application.

[0037] This application discloses an MPP power pipe clamping and cutting device.

[0038] Reference Figure 1 , Figure 2 and Figure 3 An MPP power pipe clamping and cutting device includes a support base 1, a cutting frame 2 on the support base 1, a cutting blade 3 rotatably connected to the cutting frame 2, a cutting motor 6 fixed on the cutting frame 2, the output end of the cutting motor 6 passing through the cutting frame 2 and fixedly connected to the cutting blade 3, a cutting moving mechanism 5 between the cutting frame 2 and the support base 1, and a symmetrical support mechanism 4 on the support base 1. The symmetrical support mechanism 4 includes two support rollers 41 symmetrically arranged on the support base 1, the two support rollers 41 being located on both sides of the cutting blade 3, and a support roller 42 being arranged on one side of the support rollers 41.

[0039] When using this power pipe clamping and cutting device, first move the power pipe to be cut onto the support base 1, ensuring that both the retained end and the cutting end of the power pipe are positioned on the symmetrical support mechanism 4. The symmetrical support mechanism 4 clamps and supports the power pipe. Then, start the cutting motor 6, which drives the cutting blade 3 on the cutting frame 2 to rotate. The cutting moving mechanism 5 then moves the cutting frame 2, bringing the cutting blade 3 into contact with the power pipe. The cutting blade 3 then cuts the power pipe. During the cutting process, rotate the power pipe on the symmetrical support mechanism 4 to ensure full contact between the power pipe and the cutting blade 3, completing the cutting of the power pipe. By using the symmetrical mechanism to support both the retained end and the cutting end of the power pipe, and then using the cutting blade 3 to cut the power pipe, the stability of the power pipe during cutting is improved. This reduces the possibility of the power pipe bending due to gravity when the end to be cut is long, which could cause the cut surface to shift or tilt during cutting.

[0040] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 Both ends of the support roller 41 are rotatably connected to the support rod 43, and both ends of the support roller 42 are rotatably connected to the support rod 44. The ends of the two support rods 43 away from the support roller 41 are rotatably connected to the support base 1. The support rods 43 and 44 intersect each other and are rotatably connected in the middle. An adjustment component 45 is provided between the ends of the two support rods 44 away from the support roller 42 and the support base 1. A synchronous movement component 46 is provided on the support base 1. A pressing component 47 corresponding to the support roller 41 and the support roller 42 is provided on the support base 1.

[0041] In addition, the adjustment assembly 45 includes an adjustment block 451 disposed on the support base 1. The support base 1 has an adjustment groove 452. The adjustment block 451 is located in the adjustment groove 452. Sliding blocks 453 are fixed at both ends of the adjustment block 451. The inner wall of the adjustment groove 452 has a sliding groove 454 corresponding to the sliding block 453. The sliding block 453 is located in the sliding groove 454 and is slidably connected to the support base 1. The ends of the two support rods 44 away from the support rollers 42 are rotatably connected to the adjustment block 451.

[0042] Furthermore, the synchronous moving component 46 includes a synchronous block 461 disposed on the support base 1. The support base 1 has a moving groove 463. The synchronous block 461 is located in the moving groove 463 and is slidably connected to the support base 1. Both ends of the synchronous block 461 slide through the support base 1 and are fixedly connected to the corresponding sliding blocks 453 on the two adjusting blocks 451. A moving threaded rod 462 is disposed in the moving groove 463. One end of the moving threaded rod 462 is rotatably connected to the support base 1. The moving threaded rod 462 passes through the synchronous block 461 and is threadedly connected to the synchronous block 461.

[0043] In this embodiment, the pressing component 47 includes a support frame 471 fixed on the support base 1, a pressing block 472 is provided on the support frame 471, and two symmetrical pressing rollers 473 are rotatably connected to the pressing block 472.

[0044] In this embodiment, a support block 474 is slidably connected to the support frame 471, and a pressing threaded rod 475 is threadedly connected to the support block 474. The pressing threaded rod 475 passes through the support block 474, and one end of the pressing threaded rod 475 is rotatably connected to the pressing block 472. A limiting rod 476 is fixed on the pressing block 472. The limiting rod 476 passes through the support block 474 and is slidably connected to the support block 474.

[0045] When placing the power pipe to be cut onto the support base 1, first adjust the distance between support roller 1 41 and support roller 2 42 according to the diameter of the power pipe. During adjustment, rotate the moving threaded rod 462, which drives the synchronous block 461 to move within the moving groove 463. During the movement, the moving block drives the two adjusting blocks 451, which in turn drive the corresponding support rod 2 44, causing the support rod 2 44 to rotate relative to support rod 1 43. Driven by support rod 1 43 and support rod 2 44, support roller 1 41 and support roller 2 42 move away from or closer to each other. Then, the power pipe passes through support roller 1 41 and support roller 2 42, allowing the corresponding support roller 1 41 and support roller 2 42 to support the retained end and the cut end of the power pipe. Then, move the support block 474, which drives the downward threaded rod 475, causing the downward threaded rod 475 to move further away from the cut end. The threaded rod 475 drives the lower pressure block 472, which in turn moves the two lower pressure rollers 473 above the power pipe. Then, the threaded rod 475 is rotated, causing it to move on the support block 474. This causes the threaded rod 475 to drive the lower pressure block 472, which, under the constraint of the limit rod 476, causes the two lower pressure rollers 473 to abut against the power pipe, thus clamping and fixing the power pipe. By using the two support rollers 1 41 and 2 42 to support the retained and cut ends of the power pipe, and then using the two lower pressure rollers 473 to press down and abut against the power pipe, the retained and cut ends of the power pipe are clamped and supported synchronously. This reduces the possibility of the power pipe bending due to gravity when the end to be cut is long, which could cause the cut surface to shift or tilt during cutting.

[0046] Reference Figure 2 and Figure 3 A cover plate 7 is provided on the moving groove 463, and the cover plate 7 is fixedly connected to the support base 1. The cover plate 7 is fixed above the moving groove 463 to close the moving groove 463, allowing the synchronization block 461 to move within the closed moving groove 463. The cover plate 7 blocks the debris generated during the cutting of the power pipe. By fixing the cover plate 7 above the moving groove 463, the debris generated during the cutting of the power pipe can be reduced from entering the moving groove 463 and affecting the movement of the synchronization block 461.

[0047] Reference Figure 2 , Figure 3 and Figure 4The cutting moving mechanism 5 includes a movable vertical rod 51 fixed on the support base 1, a movable horizontal rod 52 slidably connected to the movable vertical rod 51, a vertical threaded rod 53 rotatably connected to the movable vertical rod 51, the vertical threaded rod 53 passing through the movable horizontal rod 52 and threadedly connected to the movable horizontal rod 52, a drive motor 55 fixed to one end of the movable vertical rod 51, the output end of the drive motor 55 passing through the movable vertical rod 51 and fixedly connected to the vertical threaded rod 53, a transverse threaded rod 54 rotatably connected to the movable horizontal rod 52, a cutting frame 2 slidably connected to the movable horizontal rod 52, the transverse threaded rod 54 passing through the cutting frame 2 and threadedly connected to the cutting frame 2, a drive motor 56 fixed to one end of the movable horizontal rod 52, the output end of the drive motor 56 passing through the movable horizontal rod 52 and fixedly connected to the transverse threaded rod 54.

[0048] When cutting the power pipe, firstly, based on the position of the power pipe, drive motor 2 56 drives the horizontal threaded rod 54, which in turn drives the cutting frame 2. The cutting frame 2 then moves the cutting blade 3 directly above the power pipe. Next, drive motor 1 55 drives the vertical threaded rod 53, which in turn drives the moving horizontal bar 52. The moving horizontal bar 52 moves on the moving vertical bar 51, bringing the cutting blade 3 into contact with the power pipe and allowing it to cut. During the cutting process, the power pipe can be manually rotated from the outside to ensure full contact between the pipe and the cutting blade 3, completing the cutting. By moving the cutting frame 2 on the moving horizontal bar 52 and then on the moving vertical bar 51, the height and position of the cutting blade 3 can be adjusted, making it convenient to cut power pipes of different diameters and easily adjust the position of the cutting blade 3.

[0049] Working Principle: When using this power pipe clamping and cutting device, firstly, adjust the distance between support roller 1 41 and support roller 2 42 according to the diameter of the power pipe. During adjustment, rotate the moving threaded rod 462. The moving threaded rod 462 drives the synchronous block 461 to move within the moving groove 463. During the movement of the moving block, it drives the two adjusting blocks 451, which in turn drive the corresponding support rod 2 44, causing the support rod 2 44 to rotate relative to the support rod 1 43. Under the drive of the support rod 1 43 and support rod 2 44, the support roller 1 41 and support roller 2 42 move away from or closer to each other. Then, the power pipe passes through the support roller 1 41 and support roller 2 42, allowing the corresponding support roller 1 41 and support roller 2 42 to support the retained end and the cutting end of the power pipe. Then, move the support block 474, which drives the pressing threaded rod 475, which in turn drives the pressing block 472, causing the pressing threaded rod 475 to drive the pressing block 472, thus lowering the pressure... Block 472 drives the two lower pressure rollers 473 to move above the power pipe. Then, the lower pressure threaded rod 475 is rotated, allowing it to move on the support block 474. The lower pressure threaded rod 475 drives the lower pressure block 472, which, under the restriction of the limit rod 476, drives the two lower pressure rollers 473 to abut against the power pipe, thus clamping and fixing the power pipe. According to the position of the power pipe, the drive motor 2 56 drives the horizontal threaded rod 54, which drives the cutting frame 2. The cutting frame 2 drives the cutting blade 3 to move directly above the power pipe. Then, the drive motor 1 55 drives the vertical threaded rod 53, which drives the moving horizontal bar 52. The moving horizontal bar 52 moves on the moving vertical bar 51, allowing the cutting blade 3 to contact the power pipe and cut it. During the cutting process, the power pipe is manually rotated from the outside to ensure full contact between the power pipe and the cutting blade 3, thus completing the cutting of the power pipe.
