Abstract
Description
Technical Field
[0001] This invention belongs to the field of prestressed tensioning technology, specifically relating to a steel strand cutting device. Background Technology
[0002] Prestressing tensioning is the process of applying tension to a structural member in advance, causing the member to bear compressive stress and thus deform to cope with the loads on the structure itself, including the weight of the member, wind load, snow load, seismic load, etc.
[0003] Before an engineering structural member bears an external load, prestress is applied to the steel strands in the tension module to improve the member's bending resistance and stiffness, delay the appearance of cracks, and increase the member's durability. In the case of mechanical structures, this means pre-stressing them, which has the advantage of increasing the rigidity of the structure itself and reducing vibration and elastic deformation. This can significantly improve the elastic strength of the tension module, making it more resistant to external loads.
[0004] During prestressing tensioning, steel strands need to be threaded through the structural members of the engineering structure. Tensioning jacks are used to tension the steel strands, and anchorages are used to fix them after tensioning. To facilitate tensioning, the length of the steel strands must be greater than the length of the structural members during fabrication. Therefore, after the anchorages fix the steel strands, a relatively long section of steel strand will remain on the outside of the structural members, requiring cutting. Since the steel strands are suspended after tensioning, and to avoid the high temperature affecting the structure of the steel strands, a handheld cutting machine is generally used to cut them. Currently, existing cutting equipment is perpendicular to the steel strand when cutting it horizontally. However, due to the small space reserved at the tensioning position of the steel strands, the cutting equipment cannot accurately cut the steel strands. Summary of the Invention

[0009] In a preferred embodiment, a bottom clamping plate is fixedly provided at the end of the insertion rod away from the end rotating cylinder, and a bolt for clamping the cutting disc is threadedly connected to the bottom clamping plate, so that the cutting disc can be clamped and fixed between the bolt and the bottom clamping plate.
[0010] In a preferred embodiment, an externally threaded cylinder is fixedly installed on one side of the housing located at the end through hole. The insertion rod rotatably passes through the externally threaded cylinder. A limiting ring is slidably installed inside the externally threaded cylinder. The limiting ring is rotatably sleeved on the insertion rod via a bearing. An internally threaded cylinder is rotatably installed on the limiting ring via a bearing. The internally threaded cylinder is threadedly connected to the externally threaded cylinder. The insertion rod rotatably passes through the internally threaded cylinder.

When the insertion rod is inserted into the side rotating cylinder, the limiting ring is slidably installed inside the side externally threaded cylinder, and the internally threaded cylinder is threadedly connected to the externally threaded cylinder.
[0011] In a preferred embodiment, the housing has multiple end limiting holes on one side of the end through hole, all of which are located inside the end external threaded cylinder, and the end through hole is located between the multiple end limiting holes.

By inserting the insertion rod into the side drum or the end drum, the position of the cutting blade on the machine housing can be adjusted. When the cutting blade is located at the end of the machine housing, it is easy to insert the cutting blade into a smaller space for cutting, avoiding obstruction of the machine housing by engineering structural components and ensuring accurate cutting of the steel strand.
[0019] This steel strand cutting equipment is equipped with a handle, which allows the machine housing to be picked up via the handle, fixing ring, and lifting rod.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0031] For examples, please refer to Figure 1-8 The present invention provides a steel strand cutting device, including a housing 1, a drive motor 2, and a cutting blade 3 for cutting steel strands. The housing 1 has a button for controlling the start and stop of the drive motor 2 and a button for controlling the forward and reverse rotation of the drive motor 2. The drive motor 2 can rotate in both directions, i.e., clockwise and counterclockwise. The clockwise or counterclockwise rotation of the drive motor 2 can be controlled by the button on the housing 1. The housing 1 is also provided with a connecting mechanism 4 connected to the output shaft of the drive motor 2 for driving the cutting blade 3 to rotate.
[0032] In this embodiment, please refer to Figure 4The connecting mechanism 4 includes a transmission rod 401, a driving bevel gear 402, and a driven bevel gear 403. All three are rotatably mounted within the housing 1. One end of the transmission rod 401 is fixedly connected to the end of the output shaft of the drive motor 2. A main bracket 404 for mounting the transmission rod 401 and a secondary bracket 405 for mounting the driven bevel gear 403 are also fixedly mounted within the housing 1. The end of the transmission rod 401 furthest from the drive motor 2 rotatably passes through the main bracket 404 via a bearing and connects with the driving bevel gear 403. The bevel gear 402 is fixedly connected, and the drive motor 2 can drive the transmission rod 401 to rotate, so that the transmission rod 401 can drive the driving bevel gear 402 to rotate. A side rotating cylinder 406 is fixedly installed on the driven bevel gear 403. The side rotating cylinder 406 rotates through the secondary bracket 405 through the bearing. The driving bevel gear 402 and the driven bevel gear 403 mesh, so that the driving bevel gear 402 can drive the driven bevel gear 403 to rotate around the side rotating cylinder 406 as the axis. The housing 1 is provided with a side through hole 407. The inner side of the side through hole 407... The inner diameter of the side rotating cylinder 406 is larger than that of the side rotating cylinder 406. The inner cavity of the side rotating cylinder 406 is prismatic. The side through hole 407 is aligned with the inner cavity of the side rotating cylinder 406. The side of the drive bevel gear 402 away from the transmission rod 401 is rotatably mounted on the transmission assembly 5. The housing 1 has an end through hole 409. The inner diameter of the end through hole 409 is larger than that of the end rotating cylinder 408. The inner cavity of the end rotating cylinder 408 is prismatic. The end through hole 409 is aligned with the inner cavity of the end rotating cylinder 408. A rod 4010 is inserted into the end rotating cylinder 408. The rod 4010 is prismatic and matches the inner cavity of the side rotating cylinder 406 and the inner cavity of the end rotating cylinder. That is, after the rod 4010 is inserted into the end rotating cylinder 408 or the side rotating cylinder 406, the end rotating cylinder 408 and the side rotating cylinder 406 can drive the rod 4010 to rotate. The end of the rod 4010 away from the end rotating cylinder 408 rotates through the end through hole 409 and connects with the cutting blade 3. The rod 4010 can rotate through the side through hole 407 and be inserted into the side rotating cylinder 406.
[0033] In this embodiment, please refer to Figure 4The transmission assembly 5 includes a rotating rod 501, a driving gear 502, and a driven gear 503. A fixing plate 504 for mounting the rotating rod 501 and the driven gear 503 is also fixedly installed inside the housing 1. The rotating rod 501 is fixedly installed on the side of the driving bevel gear 402 away from the transmission rod 401. The end of the rotating rod 501 away from the driving bevel gear 402 passes through the fixing plate 504 via a bearing and is fixedly connected to the driving gear 502. The driving bevel gear 402 can drive the rotating rod 501 to rotate, thus enabling the rotating rod 501 to drive the driving gear 502 to rotate. A connecting cylinder is fixedly installed on one side of the driven gear 503, and the connecting cylinder is rotatably mounted on the fixing plate 504 via a bearing. On the upper part, the driving gear 502 meshes with the driven gear 503, so that the rotating rod 501 can drive the driven gear 503 to rotate on the fixed plate 504 with the connecting cylinder as the axis through the driving gear 502. The end rotating cylinder 408 is fixedly set on the side of the driven gear 503 away from the connecting cylinder, so that the driven gear 503 can drive the end rotating cylinder 408 to rotate, thereby achieving the effect of driving the cutting blade 3 to rotate. Since the end space of the housing 1 is small, the center position of the drive motor 2 cannot be aligned with the center position of the end rotating cylinder 408. Therefore, the effect of the cooperation between the driving gear 502 and the driven gear 503 achieves the misalignment effect, and can ensure the normal rotation of the cutting blade 3.
[0034] The insertion rod 4010 is fixedly provided with a bottom clamping plate 6 at the end away from the end rotating cylinder 408. The bottom clamping plate 6 is threaded with a bolt 7 for clamping the cutting disc 3, so that the cutting disc 3 can be clamped and fixed between the bolt 7 and the bottom clamping plate 6. The smaller end of the bolt 7 is passed through the hole on the cutting disc 3 and threaded to the bottom clamping plate 6, so that the larger end of the bolt 7 and the bottom clamping plate 6 can clamp and fix the cutting disc 3, which is convenient for the installation and removal of the cutting disc 3 and improves convenience.
[0035] In this embodiment, please refer to Figure 3-4An externally threaded cylinder 8 is fixedly installed on one side of the housing 1 at the end through hole 409. The insertion rod 4010 rotatably passes through the externally threaded cylinder 8. A limit ring 9 is slidably installed inside the externally threaded cylinder 8. The limit ring 9 is rotatably sleeved on the insertion rod 4010 via a bearing. An internally threaded cylinder 10 is rotatably installed on the limit ring 9 via a bearing. The internally threaded cylinder 10 is threadedly connected to the externally threaded cylinder 8. The insertion rod 4010 rotatably passes through the internally threaded cylinder 10. A side externally threaded cylinder 11 is fixedly installed on one side of the housing 1 at the side through hole 407. When the insertion rod 4010 is inserted into the side rotating cylinder 406, the limit... The positioning ring 9 is slidably disposed inside the external threaded cylinder 11, and the internal threaded cylinder 10 is threadedly connected to the external threaded cylinder 11. The insertion rod 4010 is inserted into the end rotating cylinder 408, so that the positioning ring 9 can be located inside the end external threaded cylinder 8. Rotating the internal threaded cylinder 10 to connect with the end external threaded cylinder 8 can clamp and fix the positioning ring 9 inside the end external threaded cylinder 8, ensuring that the insertion rod 4010 is always located inside the end rotating cylinder 408, thereby ensuring the rotation of the cutting blade 3. When the insertion rod 4010 is inserted into the side rotating cylinder 406, the principle of the positioning ring 9 being clamped inside the external threaded cylinder 11 is the same.
[0036] The housing 1 has multiple end limiting holes 12 on one side of the end through hole 409. These holes 12 are all located within the end external threaded cylinder 8, and the end through hole 409 is located between the multiple end limiting holes 12. Multiple limiting rods 13 are fixedly installed on the limiting ring 9, and each limiting rod 13 is inserted into one of the multiple end limiting holes 12. The housing 1 also has multiple side limiting holes 14 on one side of the edge limiting hole 14. These holes 14 are all located within the edge external threaded cylinder 11, and the edge... The through hole 407 is located between multiple end limiting holes 12. When the limiting ring 9 is located in the side external threaded cylinder 11, multiple limiting rods 13 are respectively inserted into multiple side limiting holes 14. When the limiting ring 9 is clamped in the end external threaded cylinder 8, the limiting rods 13 can be inserted into the end limiting holes 12, thereby preventing the limiting ring 9 from rotating with the insertion rod 4010 due to centrifugal force, thus improving stability. Similarly, when the insertion rod 4010 is inserted into the side rotating cylinder 406, the limiting rods 13 can be inserted into the side limiting holes 14.
[0037] In this embodiment, please refer to Figure 1-2 A dust cover 15 is threadedly connected to the external threaded cylinder 11 on the side, so that the dust cover 15 can block the side through hole 407 and multiple side limiting holes 14. The dust cover 15 can be threadedly connected to the external threaded cylinder 8 at the end, so that the dust cover 15 can block the end through hole 409 and multiple end limiting holes 12. When the dust cover 15 blocks the end through hole 409, end limiting holes 12, side through hole 407 and side limiting holes 14, it can prevent other impurities from entering the housing 1, thus improving safety.
[0038] In this embodiment, please refer to Figure 7-8 A lifting rod 16 is fixedly installed on the dust cover 15. A fixing ring 17 is sleeved on the lifting rod 16. A handle 18 for picking up the machine housing 1 is fixedly installed on the fixing ring 17. The handle 18 is located on the side of the lifting rod 16 away from the cutting blade 3. The machine housing 1 can be picked up easily through the handle 18, which improves convenience and stability.
[0039] The fixing ring 17 is slidably sleeved on the lifting rod 16. One end of the lifting rod 16 has a protrusion that restricts the fixing ring 17 from disengaging. The handle 18 has a receiving hole 19 for securing the steel strand. The fixing ring 17 has a through hole 20 that facilitates the passage of the steel strand and communicates with the receiving hole 19. The lifting rod 16 has a strip hole 21 that allows the steel strand to pass through and communicates with the through hole 20 and the receiving hole 19. The steel strand can be inserted into the receiving hole 19, the strip hole 21, and the through hole 20, so that the handle 18 can be secured. Handle 18 can support one end of the steel strand to prevent the steel strand from being fully compressed during cutting and to ensure the flatness of the cut surface. When cutting the steel strand, the housing 1 and the cutting blade 3 will move relative to the handle 18, so that the handle 18 moves on the lifting rod 16 through the fixing ring 17. At this time, the steel strand moves in the strip groove, which facilitates the contact between the cutting blade 3 and the steel strand. The inner cavities of the lifting rod 16 and the fixing ring 17 are not standard circles, so that the fixing ring 17 can only slide linearly on the lifting rod 16 and cannot rotate.
[0040] The connection between the fixing ring 17 and the handle 18 is provided with an "I"-shaped positioning groove 22. An "I"-shaped positioning block 23 matching the positioning groove 22 is slidably arranged in the positioning groove 22. A groove 24 is provided on the lifting rod 16. One end of the positioning block 23 can pass through one end of the positioning groove 22 and be inserted into the groove 24. When cutting, if it is not necessary to support the steel strand, in order to improve stability, it is necessary to ensure the stability of the handle 18. Push the positioning block 23 to make it slide in the positioning groove 22 so that one end of the positioning block 23 can be inserted into the groove 24, thereby preventing the fixing ring 17 from causing the handle 18 to slide randomly.
[0041] In this embodiment, please refer to Figure 8 The lifting rod 16 has a process groove 25 at the end away from the dust cover 15, which matches the end of the bolt 7. The bolt 7 can be inserted into the process groove 25, so that the lifting rod 16 can drive the bolt 7 to rotate. After the dust cover 15 is separated from the machine housing 1, the process groove 25 is fitted onto the bolt 7. Rotating the lifting rod 16 makes it easy to rotate the bolt 7 through the process groove 25, which facilitates the disassembly and installation of the bolt 7. The cutting disc 3 can be replaced without other tools, which improves convenience.
[0042] Based on the above, the working principle of this solution is as follows:
[0043] In use, first, insert the insertion rod 4010 through the end through hole 409 and then insert it into the end rotating cylinder 408. At this time, the limiting ring 9 is located inside the end external threaded cylinder 8, and the limiting rod 13 is inserted into the end limiting hole 12. Rotate the internal threaded cylinder 10 to make it threadedly connected with the end external threaded cylinder 8, which can fix the limiting ring 9 on the machine housing 1. Then, pass the small end of the screw through the hole on the cutting blade 3 and connect it to the bottom clamping plate 6. Use the process groove 25 on the lifting rod 16 to tighten the bolt 7. The drive motor 2 can be started by the button on the machine housing 1, so that the drive motor 2 can drive the driving bevel gear 402 to rotate through the transmission rod 401. In turn, the driving bevel gear 402 can drive the driving gear 502 to rotate through the rotating rod 501. The driving gear 502 can drive the end rotating cylinder 408 to rotate through the driven gear 503, which in turn can drive the cutting blade 3 to rotate through the insertion rod 4010. To achieve the cutting effect, similarly, the insertion rod 4010 can be installed and fixed on the side rotating drum 406. When the drive motor 2 drives the active bevel gear 402 to rotate through the transmission rod 401, the active bevel gear 402 can drive the side rotating drum 406 to rotate through the driven bevel gear 403, and then drive the cutting blade 3 to rotate through the rotating rod 501 to achieve the cutting effect. When cutting, if the steel strand is short and will not bend, push the positioning block 23 to insert it into the groove 24, and then hold the handle 18 and the machine housing 1 to drive the cutting blade 3 to cut the steel strand. If the steel strand is long and easy to bend, insert one end of the steel strand into the receiving hole 19, the strip hole 21 and the through hole 20, and slide the positioning block 23 to separate from the groove 24, so that the handle 18 can move on the lifting rod 16 through the fixing ring 17, and then drive the steel strand to move relative to the cutting blade 3, so that the cutting blade 3 can cut the steel strand.
