Description

Technical Field

[0001] This invention relates to the field of cable processing technology, specifically to a secondary cable straightening and straightening device. Background Technology

[0002] The secondary cable straightening device is a specialized tool used in power construction, especially in substations and distribution rooms. Its core function is to quickly and safely straighten the bent and tangled cores of secondary cables after the outer sheath has been stripped, so that subsequent wiring can be carried out.

[0003] Existing secondary cable straightening devices typically use an electric wrench to perform cable straightening operations. Then, one end of the bent wire core is clamped and fixed with a fixing block and its pressure block, while the other end is clamped with a pulling block and its pressure block. Then, the pulling block is pulled along the guide rail away from the fixing block, and the wire core clamped in the middle is forcibly stretched, thus straightening it.

[0004] The inventors of this application discovered in their research that the core defect of the aforementioned prior art is that: the way electric wrenches untangle cables usually requires changing the structure of their output end according to the cable size to adapt to the cable untangling and straightening requirements. However, during the process of changing the wrench head, the operator needs to manually switch modes or use an additional control switch to avoid safety hazards caused by misoperation. When the device is not in a completely de-energized state, the motor can easily be injured if it is accidentally started. Summary of the Invention

[0005] This invention provides a secondary cable straightening and straightening device, which solves the problem that operators need to manually switch modes or use additional control switches to avoid safety hazards caused by misoperation, and achieves the effect of automatic power interruption during installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a secondary cable straightening and unwinding device, comprising a device housing, a pull head, and a plug-in block. Heat dissipation grooves are provided on both sides of the device housing. A servo motor is installed inside the device housing. A drive rod is fixedly connected to the output end of the servo motor. The drive rod is rotatably connected inside the device housing. A fixing block is fixedly connected inside the drive rod. A hollow rod is rotatably connected inside the drive rod. A polygonal rod is slidably connected inside the hollow rod. An inner sliding rod is fixedly connected to one end of the polygonal rod. The inner sliding rod is slidably connected inside the drive rod. A compression spring is fixedly connected to one end of the inner sliding rod through the drive rod. A release element is fixedly connected to one end of the inner sliding rod. The plug-in block is rotatably connected to the other end of the inner sliding rod.

[0007] By adopting the above technical solution, when the detachment part is completely detached from the fixed block, the circumferential fixed connection between the drive rod and the inner slide rod is completely cut off. At this time, even if the servo motor continues to run and makes the drive rod rotate, the rotational motion cannot be transmitted to the inner slide rod and the plug block. The plug block and the pull head remain stationary, effectively preventing the head body from rotating due to misoperation or motor inertia during the installation process, thus avoiding damage to the threads or causing installation deviation.

[0008] Preferably, an auxiliary block is fixedly connected inside the housing of the device, a guide rail is fixedly connected inside the auxiliary block, a guide block is rotatably connected to the outside of the plug-in block, the guide block is slidably connected to the guide rail, a plug-in hole is opened on one side of the plug-in block, and a fixing body is fixedly connected inside the plug-in block.

[0009] Preferably, a telescopic rod two is fixedly connected inside the fixed body, and an inner slider is fixedly connected to one end of the telescopic rod two, with the inner slider slidably connected inside the fixed body.

[0010] Preferably, the top of the inner slider is fixedly connected to a spring through the interior of the fixing body, and the bottom of the inner slider is fixedly connected to a hemispherical block.

[0011] Preferably, a trapezoidal block is fixedly connected to one side of the inner slider, and the trapezoidal block is slidably connected to one side of the fixed body.

[0012] Preferably, a ratchet is fixedly connected to one side of the guide block, and a telescopic rod is fixedly connected inside the plug-in block.

[0013] Preferably, one end of the telescopic rod is fixedly connected to a sliding plate, and one side of the sliding plate is fixedly connected to a compression spring through the inside of a plug block.

[0014] Preferably, a sliding ring is fixedly connected to the outside of the sliding plate, the sliding ring is slidably connected to the inside of the plug-in block, and a ratchet is fixedly connected to one side of the sliding ring.

[0015] Preferably, a locking head is fixedly connected to the other side of the sliding ring, and the locking head is positioned opposite to the trapezoidal block.

[0016] Preferably, one end of the pull head is fixedly connected to a plug rod, and one end of the plug rod is fixedly connected to a hexagonal rod.

[0017] By adopting the above technical solution, after the head body is installed and the axial thrust is released, the compression spring automatically releases its elasticity, pushing the inner slide rod and the disengagement part to reset. The drive rod and the plug block resume transmission connection, and the wrench can enter the next working cycle. The operation is simple and efficient. The entire power-off disconnection action is achieved entirely by mechanical force, without the need for additional electrical control or sensor intervention. The response is direct and without delay, and it is not affected by electromagnetic interference. The operation is stable and reliable.

[0018] This invention provides a secondary cable straightening and straightening device. It has the following advantages:

[0019] 1. This invention provides power to the device by setting a servo motor to rotate the drive rod. During the installation of the zipper head, the plug block is pushed by force, causing the inner slide rod to slide inside the drive rod. During this process, the polygonal rod slides inside the hollow rod and compresses the compression spring. At this time, the release part disengages from the fixed block, and the rotation of the drive rod no longer causes the inner slide rod and the plug block to rotate. The operator does not need to manually switch modes or use additional control switches. The power is automatically interrupted during the installation process, reducing the risk of misoperation, improving work safety and user experience, and solving the safety hazards caused by misoperation during the installation of the zipper head.

[0020] 2. This invention, by setting up a plug-in block, allows the pull head to be inserted into the plug-in block using the plug rod and hexagonal rod. During this process, the inner slider and hemispherical locking block slide inside the fixed body, and the spring structure allows the hemispherical locking block to engage with the outside of the plug rod, thus facilitating the easy removal and installation of the pull head. This allows users to change the pull head according to actual untying or straightening needs. Users can assemble the structure simply by plugging and unplugging, solving the problem of inconvenient pull head replacement.

[0021] 3. By setting a guide block and using a guide rail for limiting, the present invention ensures that the guide block remains stationary inside the auxiliary block during the rotation of the plug-in block driven by the servo motor. The rotating ratchet two and the sliding ring are pushed by the ratchet one, causing the compression spring two to be compressed. At this time, the locking head is attached to the outside of the trapezoidal block, and the hemispherical block cannot rise, thereby playing a role in stabilizing and fixing the pull head. Furthermore, it increases the stability of the pull head when the device is started, solving the problem of unstable installation of the pull head during device operation.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a secondary cable straightening and unwinding device, comprising a device housing 1, a pull head 4, and a plug-in block 11. Heat dissipation grooves 2 are provided on both sides of the device housing 1. A servo motor 7 is installed inside the device housing 1. A drive rod 8 is fixedly connected to the output end of the servo motor 7. The drive rod 8 is rotatably connected inside the device housing 1. A fixing block 17 is rotatably connected inside the drive rod 8. A hollow rod 14 is fixedly connected inside the drive rod 8. A polygonal rod 15 is slidably connected inside the hollow rod 14. An inner slide rod 10 is fixedly connected to one end of the polygonal rod 15. The inner slide rod 10 is slidably connected inside the drive rod 8. A compression spring 16 is fixedly connected to one end of the inner slide rod 10 through the inside of the drive rod 8. A release member 18 is fixedly connected to one end of the inner slide rod 10. The plug-in block 11 is rotatably connected to the other end of the inner slide rod 10.

[0033] Specifically, during the installation of the pull head 4, the inward insertion of the pull head 4 causes the insertion block 11 to retract toward the inside of the device housing 1, and causes the inner slide rod 10 to slide inside the drive rod 8. During this process, the polygonal rod 15 slides inside the hollow rod 14, and the compression spring 16 is also compressed until the release piece 18 disengages from the fixing block 17. The rotation of the drive rod 8 can no longer drive the inner slide rod 10 to rotate. After the pull head 4 is installed, the compression spring 16 pops the inner slide rod 10 out again, so that the release piece 18 re-contacts the fixing block 17.

[0034] After the servo motor 7 is started, the drive rod 8 rotates inside the device housing 1, and the fixing block 17 pushes the release member 18 and the inner slide rod 10 to rotate at high speed. The plug block 11 and the pull head 4 also rotate, thereby causing the cable installed inside the pull head 4 to be rotated and unwired.

[0035] Please see the appendix Figure 3 and attached Figure 7 An auxiliary block 3 is fixedly connected inside the housing 1 of the device. A guide rail 9 is fixedly connected inside the auxiliary block 3. A guide block 12 is rotatably connected to the outside of the plug-in block 11. The guide block 12 is slidably connected to the guide rail 9. A plug-in hole 13 is opened on one side of the plug-in block 11. A fixing body 25 is fixedly connected inside the plug-in block 11.

[0036] A telescopic rod 26 is fixedly connected inside the fixed body 25. One end of the telescopic rod 26 is fixedly connected to an inner slider 28, which is slidably connected inside the fixed body 25.

[0037] The top of the inner slider 28 is fixedly connected to a spring 27 through the inside of the fixed body 25, and the bottom of the inner slider 28 is fixedly connected to a hemispherical block 29.

[0038] Specifically, the pull head 4 can be inserted into the insertion hole 13 of the insertion block 11 using the insertion rod 5 and the hexagonal rod 6. During the insertion of the insertion rod 5, the hemispherical locking block 29 will be retracted into the fixed body 25 under force, and the inner slider 28 will also slide inside the fixed body 25. The telescopic rod 26 and the spring 27 will also be compressed until the hemispherical locking block 29 is pushed into the outside of the insertion rod 5 by the spring 27, thereby fixing the pull head 4 with the hemispherical locking block 29. Similarly, the user can pull the pull head 4 to disengage the insertion rod 5 and the hexagonal rod 6 from the insertion block 11.

[0039] Please see the appendix Figure 3 , Figure 7 and attached Figure 8 A trapezoidal block 30 is fixedly connected to one side of the inner slider 28, and the trapezoidal block 30 is slidably connected to one side of the fixed body 25.

[0040] A ratchet 19 is fixedly connected to one side of the guide block 12, and a telescopic rod 24 is fixedly connected inside the plug block 11.

[0041] One end of the telescopic rod 24 is fixedly connected to a sliding plate 22, and one side of the sliding plate 22 is fixedly connected to a compression spring 23 through the inside of the plug block 11.

[0042] A sliding ring 21 is fixedly connected to the outside of the sliding plate 22. The sliding ring 21 is slidably connected inside the plug block 11. A ratchet 20 is fixedly connected to one side of the sliding ring 21.

[0043] A locking head 31 is fixedly connected to the other side of the sliding ring 21, and the locking head 31 is positioned opposite to the trapezoidal block 30.

[0044] One end of the pull head 4 is fixedly connected to the insertion rod 5, and one end of the insertion rod 5 is fixedly connected to the hexagonal rod 6.

[0045] Specifically, during the movement of the plug-in block 11, the guide block 12 can slide outside the guide rail 9. After the plug-in block 11 is reset, when the servo motor 7 is started, the plug-in block 11 will rotate inside the auxiliary block 3, and the guide block 12 will be locked and fixed by the guide rail 9. The second ratchet 20 will rotate outside the first ratchet 19, causing the sliding ring 21 and the sliding plate 22 to move towards the side of the fixed body 25. The second compression spring 23 and the first telescopic rod 24 will also be compressed. At this time, the locking head 31 will abut against one side of the trapezoidal block 30, thereby fixing the hemispherical block 29 and preventing the pull head 4 from coming off.

[0046] Work process: During the installation of the pull head 4, the inward insertion of the pull head 4 will cause the insertion block 11 to retract into the device housing 1, and cause the inner slide rod 10 to slide inside the drive rod 8. During this process, the polygonal rod 15 will slide inside the hollow rod 14, and the compression spring 16 will also be compressed until the release part 18 disengages from the fixing block 17. The rotation of the drive rod 8 can no longer drive the inner slide rod 10 to rotate. After the pull head 4 is installed, the compression spring 16 will pop the inner slide rod 10 out again, so that the release part 18 will re-contact the fixing block 17.

[0047] After the servo motor 7 is started, the drive rod 8 rotates inside the device housing 1, and the fixing block 17 pushes the release part 18 and the inner slide rod 10 to rotate at high speed. The plug block 11 and the pull head 4 also rotate, thereby causing the cable installed inside the pull head 4 to be rotated and unwired.

[0048] The pull head 4 can be inserted into the insertion hole 13 of the insertion block 11 using the insertion rod 5 and the hexagonal rod 6. During the insertion of the insertion rod 5, the hemispherical locking block 29 will be retracted into the fixed body 25 under force, and the inner slider 28 will also slide inside the fixed body 25. The telescopic rod 26 and the spring 27 will also be compressed under force until the hemispherical locking block 29 is pushed into the outside of the insertion rod 5 by the spring 27, thereby fixing the pull head 4 with the hemispherical locking block 29. Similarly, the user can pull the pull head 4 to disengage the insertion rod 5 and the hexagonal rod 6 from the insertion block 11.

[0049] During the movement of the plug-in block 11, the guide block 12 can slide outside the guide rail 9. After the plug-in block 11 is reset, when the servo motor 7 is started, the plug-in block 11 will rotate inside the auxiliary block 3, and the guide block 12 will be locked and fixed by the guide rail 9. The second ratchet 20 will rotate outside the first ratchet 19, causing the sliding ring 21 and the sliding plate 22 to move towards the side of the fixed body 25. The second compression spring 23 and the first telescopic rod 24 will also be compressed. At this time, the locking head 31 will abut against one side of the trapezoidal block 30, thereby fixing the hemispherical block 29 and preventing the pull head 4 from coming off.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
