Description

Technical Field

[0001] This application relates to the field of threading equipment technology, and in particular to a threading guide device. Background Technology

[0002] Cable pulleys (usually referring to utility poles, communication poles, etc.) are common support structures in power and communication infrastructure, mainly used for laying cables, wires, or fiber optic cables. In the field of pipeline construction and maintenance, cable pulleys serve as a core tool for cable laying, improving the convenience of cable installation.

[0003] If misalignment occurs at the connection ends of the two pipes when the threading rod 73 moves inside the pipe, as shown in the attached... Figure 1 As shown, the bottom of the downstream pipe connection end 71 is higher than the bottom of the upstream pipe connection end 72. At this time, the cable pull rod 73 is easily stuck below the bottom of the downstream pipe connection end 71, making it difficult for the cable pull rod 73 to enter the downstream pipe, thereby reducing the convenience of laying the cable in the pipe. Utility Model Content

[0004] To address the problem that cable guide poles easily get stuck at the bottom of downstream pipes, making it difficult for them to enter the pipes and reducing the convenience of cable laying, this application provides a cable guiding device.

[0005] The threading guide device provided in this application adopts the following technical solution:

[0006] A threading guide device includes a base and a guide rod. The base is connected to a traction rope. The guide rod is disposed at the front end of the base and connected to the base via a rotation adjustment assembly. The rotation adjustment assembly can drive the guide rod to rotate around the base so that the front end of the guide rod is higher than the bottom of the downstream pipe connection end. The guide rod can guide the base to slide into the downstream pipe. A vision component is provided on the guide rod or the base, which can transmit the condition inside the pipe to the outside of the pipe.

[0007] By adopting the above technical solution, the base is connected to the traction rope, and the guide rod is set at the front end of the base and connected to the base through a rotation adjustment component. This allows the guide rod to rotate around the base, thereby adjusting the height of the front end of the guide rod to be higher than the bottom of the downstream pipe connection end. This ensures that the guide rod can smoothly guide the base into the downstream pipe, improving the convenience of cable laying inside the pipe. In addition, a vision component is set on the guide rod or the base, which can transmit the condition inside the pipe to the outside of the pipe, enabling precise cable threading, avoiding blind operation, significantly reducing the risk of cable threading rod deviation, and improving the success rate of cable threading.

[0008] Preferably, the rotation adjustment assembly includes a tilt adjustment component, which includes a rotation support, a rotation shaft, and a drive component. The rotation support is connected to the base, and the rotation shaft is fixedly mounted on the guide rod and rotatably connected to the rotation support, so that the front end of the guide rod can be higher than the bottom of the downstream pipe connection end. The drive component is connected to the rotation shaft to drive the rotation shaft to rotate.

[0009] By adopting the above technical solution, the rotating support is connected to the base, and the rotating shaft is fixed to the guide rod and rotatably connected to the rotating support. This allows the front end of the guide rod to be higher than the bottom of the downstream pipe connection end. As the base and guide rod continue to move forward, the guide rod guides the base to slide into the downstream pipe, ensuring the smooth movement of the threading guide device within the pipe. The drive component is connected to the rotating shaft, further enabling precise control of the guide rod's tilt angle. This angle can be adjusted according to the height of the bottom of different downstream pipe connection ends, improving the flexibility and accuracy of the threading operation.

[0010] Preferably, the driving component includes a first motor and a bevel gear assembly. The first motor is fixedly mounted on the rotating support and connected to the rotating shaft through the bevel gear assembly, so as to drive the guide rod to rotate.

[0011] By adopting the above technical solution, the first motor is connected to the rotating shaft via a bevel gear assembly, achieving precise rotation control of the guide rod. Simultaneously, replacing manual adjustment with motor drive improves operational efficiency and accuracy, ensuring a smoother threading process.

[0012] Preferably, the rotation adjustment assembly further includes a rotation adjustment component, which includes a second motor. The second motor is fixedly connected to the base, and the output shaft of the second motor is fixedly connected to the rotation support, so that the front end of the guide rod can rotate upward.

[0013] By adopting the above technical solution, the second motor is fixedly connected to the base and drives the rotating support to rotate through its output shaft. The guide rod can stably rotate with its front end facing upwards, avoiding the phenomenon that the guide rod rotates in other directions due to angular deviation, which would lead to threading failure, thereby improving the threading success rate and operation efficiency.

[0014] Preferably, an elastic tube is fitted on both the rotating support and the guide rod. One end of the elastic tube is embedded in the rotating support, and the other end is embedded in the guide rod. The elastic tube can wrap around the rotating support and the rotating shaft.

[0015] By adopting the above technical solution, the flexible tube effectively protects the connection structure between the rotating support and the rotating shaft, preventing dust and impurities from entering, thereby improving the stability and service life of the rotation adjustment component. Simultaneously, the flexible tube can slide along the bottom of the downstream pipe connection end, preventing the hinge structure between the guide rod and the base from getting stuck at the downstream pipe connection end, making the wire guiding device move more smoothly within the pipe.

[0016] Preferably, the front end and rear end of the base are connected by a conical surface, and the conical surface has a mounting groove with an opening facing the front end of the guide rod; the vision component includes a camera disposed in the mounting groove, and the camera is positioned facing the front end of the guide rod.

[0017] By adopting the above technical solution, the camera in the vision component is positioned within the mounting groove and facing the front end of the guide rod. This allows the camera to capture real-time images of the inside of the pipe, providing the operator with intuitive visual feedback and enabling precise adjustment of the threading direction. Simultaneously, positioning the camera within the mounting groove effectively prevents it from protruding laterally from the guide groove, reducing its impact on the sliding of the guide rod.

[0018] Preferably, a transparent plate is fixedly provided on the base, and the transparent plate is disposed at the opening of the mounting groove so as to block the opening of the mounting groove.

[0019] By adopting the above technical solution, the transparent plate is placed at the opening of the mounting slot, which can effectively seal the opening of the mounting slot and prevent external dust and impurities from entering the interior of the mounting slot, thereby protecting visual components such as cameras from contamination.

[0020] Preferably, a third motor is nested and connected to the base, and a scraper is slidably provided on the conical surface. The third motor is connected to the scraper so as to be able to wipe the surface of the transparent plate.

[0021] By adopting the above technical solution, a third motor is nested and connected to the base, and a scraping component connected to the third motor is set on the conical surface. This can effectively clean the surface of the transparent plate, ensure the clarity of the vision component in complex environments, reduce the impact of dust or dirt on the camera's imaging quality, and thus improve the accuracy of the threading operation.

[0022] Preferably, the base has a water supply channel inside, the water supply channel is connected to a water supply system, and the outlet of the water supply channel faces the transparent plate so as to be able to rinse the transparent plate.

[0023] By adopting the above technical solution, a water supply channel is set up inside the base, and water is sprayed onto the transparent plate through the water supply system for rinsing. This solution can effectively remove dust and stains from the surface of the transparent plate, ensuring the clarity of the camera's field of vision in complex environments, thereby improving the accuracy and efficiency of the wiring operation.

[0024] Preferably, the water supply system includes a water storage bag and a water pump nested in the base, the water pump inlet is connected to the water storage bag, and the water pump outlet is connected to the water supply channel, so that the water pump can supply water to the water supply channel.

[0025] By adopting the above technical solution, the water storage bag of the guiding device is used to supply water to the water supply channel through a water pump, thereby reducing the water supply distance and improving the convenience of water supply.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The introduction of the vision component enables real-time monitoring of the internal condition of the pipeline. Through the vision component, it is possible to observe the cable guide device moving to the misalignment point of the pipeline. Then, by rotating the adjustment component, the guide rod is driven to rotate, so that the front end of the guide rod is higher than the bottom of the downstream pipeline connection end, ensuring that the guide rod can smoothly guide the base to slide into the downstream pipeline, improving the convenience of cable laying in the pipeline.

[0028] 2. The second motor is fixedly connected to the base and drives the rotating support to rotate through its output shaft. This ensures that the guide rod can rotate with its front end facing upwards, preventing the guide rod from rotating in other directions due to angular deviation, which could lead to threading failure and improve threading success rate and operating efficiency.

[0029] 3. The water supply system sprays water to rinse the transparent plate, and the third motor drives the scraper to clean the transparent plate, ensuring the continuous clarity of the transparent plate in complex construction environments, thereby ensuring the normal operation of the vision components and further improving the efficiency and reliability of threading.

[0041] The following is in conjunction with the appendix Figures 2-10 This application will be described in further detail.

[0042] The inventors of this application discovered that in existing cable-threading technologies, the cable-threading rod easily gets stuck below the bottom of the downstream pipe, making it difficult for the rod to enter the pipe and reducing the convenience of cable laying. To address this, this application mainly adopts the following solution, achieving the effects of multi-degree-of-freedom adjustment of the guide rod's posture, real-time monitoring of the pipe's internal condition, and automatic cleaning of the vision components.

[0043] This application discloses a threading guide device.

[0044] Reference Figure 1 ,Figure 2 A threading guide device includes a base 1 and a guide rod 2, both of which are cylindrical. The rear end of the base 1 is fixedly connected to a traction rope, and the front end of the base 1 is connected to the rear end of the guide rod 2 via a rotation adjustment assembly 3. The rotation adjustment assembly 3 can drive the guide rod 2 to rotate around the base 1, so that the front end of the guide rod 2 is higher than the bottom of the downstream pipe connection end. The guide rod 2 can guide the base 1 to slide into the downstream pipe. In this embodiment, a vision component 4 is provided on the base 1. The vision component 4 monitors the condition inside the pipe and transmits the signal to a display outside the pipe for the operator to observe the condition inside the pipe. The arrows in the attached drawings indicate the direction of movement of the threading guide device.

[0045] The introduction of vision component 4 enables real-time monitoring of the internal condition of the pipeline. Vision component 4 can observe the cable guide device moving to the misaligned part of the pipeline. Then, by rotating adjustment component 3, the guide rod 2 is driven to rotate, so that the front end of the guide rod 2 is higher than the bottom of the downstream pipeline connection end 71, ensuring that the guide rod 2 can smoothly guide the base 1 into the downstream pipeline, improving the convenience of cable laying in the pipeline.

[0046] Reference Figure 4 , Figure 5 The front end and rear end of the base 1 are connected by a conical surface 6. The conical surface 6 includes a first conical surface 61 and a second conical surface 62. The second conical surface 62 is located in front of the first conical surface 61, and the angle between the first conical surface 61 and the axial direction of the guide rod 2 is greater than the angle between the second conical surface 62 and the axial direction of the guide rod 2.

[0047] Reference Figure 5 , Figure 6 Four mounting slots 63 are formed on the first conical surface 61, and the four mounting slots 63 are evenly arranged along the circumference of the guide rod 2, with the opening of each mounting slot 63 facing the guide rod 2. In this embodiment, the vision component 4 includes a camera 41, which corresponds one-to-one with each mounting slot 63. The camera 41 is fixedly installed in the mounting slot 63, with its lens facing the opening of the mounting slot 63 to facilitate observation of the environment around the guide rod 2. The camera 41 is powered by a battery located inside the guide rod 2. In this embodiment, the image signal collected by the camera 41 is transmitted wirelessly to a display outside the pipe. In other embodiments, the image signal collected by the camera 41 can also be transmitted wiredly to a display outside the pipe; this method is mainly used in environments with poor signal.

[0048] Reference Figure 6 , Figure 7A transparent plate 64 is fixedly provided on the base 1. In this embodiment, the transparent plate 64 is a transparent glass plate. The transparent plate 64 corresponds one-to-one with the mounting groove 63. The transparent plate 64 is fixedly installed at the opening of the mounting groove 63 and blocks the opening of the mounting groove 63. The surface of the transparent plate 64 is flush with the first conical surface 61. By setting the transparent plate 64, the opening of the mounting groove 63 is effectively blocked, preventing external dust and impurities from entering the interior of the mounting groove 63, thereby protecting the camera 41 and other visual components 4 from contamination.

[0049] Reference Figure 5 , Figure 6 The base 1 has a water supply channel 65 inside, which includes a main channel 651 and a branch channel 652. The main channel 651 is connected to the water supply system 8 through a flexible soft water pipe, so that the water supply system 8 delivers cleaning water into the main channel 651. The branch channel 652 corresponds one-to-one with the transparent plate 64. The outlet of the branch channel 652 is set on the second cone surface 62 and faces the transparent plate 64, so that the cleaning water is sprayed onto the transparent plate 64 along the outlet of the branch channel 652 to clean the transparent plate 64, effectively removing dust and stains from the surface of the transparent plate 64, ensuring the clarity of the camera 41 in complex environments, thereby improving the accuracy and efficiency of the threading operation.

[0050] Reference Figure 6 , Figure 7 and Figure 8 A third motor 661 is nested and connected to the guide rod 2 in front of the water supply channel 65. The axis of the output shaft of the third motor 661 is collinear with the axis of the base 1. The output shaft of the third motor 661 is fixedly provided with four intermediate rods 662 arranged radially along the base 1. The base 1 is provided with sliding through holes 663 for the intermediate rods 662 to pass through. The intermediate rods 662 correspond one-to-one with the sliding through holes 663. The intermediate rods 662 extend out of the base 1 through the sliding through holes 663. Each intermediate rod... A scraper 664 is fixedly provided on one end of the rod 662 that extends out of the base 1. In this embodiment, the scraper 664 is a rubber scraper. The scraper 664 corresponds one-to-one with the transparent plate 64. The scraper 664 is in contact with the first conical surface 61 and the second conical surface 62. The width of the sliding through hole 663 along the circumference of the base 1 is greater than the width of the middle rod 662 in this direction, so that the middle rod 662 drives the scraper 664 to slide back and forth on the transparent plate 64 to clean the transparent plate 64. The back of the scraper 664 is a bevel with an acute angle to the axial direction of the base 1, which prevents the base 1 from getting stuck at the downstream pipe connection and improves the smooth movement of the wire guide device in the pipe.

[0051] The water supply system 8 sprays water to the transparent plate 64 for rinsing, and the third motor 661 drives the scraper 664 to wipe the transparent plate 64, ensuring the continuous clarity of the transparent plate 64 in complex construction environments, thereby ensuring the normal operation of the vision component 4 and further improving the efficiency and reliability of threading.

[0052] Reference Figure 5 In this embodiment, the water supply system 8 includes a water storage bag 81 and a water pump 82. The water storage bag 81 is made of PVC and is nested inside the base 1. The water storage bag 81 has a water inlet with a switch, which is located on the surface of the base 1 and is normally closed. The water pump 82 is a mini water pump and is nested inside the base 1. The base 1 has a through hole communicating with the space where the water pump 82 is located, so as to realize heat dissipation of the water pump 82. The water suction end of the water pump 82 is connected to the water storage bag 81 through a pipe, and the water discharge end of the water pump 82 is connected to the main channel 651 through a pipe.

[0053] When the transparent panel 64 needs cleaning, the water pump 82 is turned on. The water pump 82 delivers water from the water storage bag 81 to the main channel 651, and then sprays it to the transparent panel 64 through the branch channel 652. The water storage bag 81 integrated into the base 1 reduces the water supply distance and improves the convenience of water supply. When the water pump 82 draws water, the water storage bag 81 can adapt to the pressure change caused by the reduction in water volume through its own deformation.

[0054] Reference Figure 5 , Figure 9 In this embodiment, the rotation adjustment assembly 3 includes a tilt adjustment component 31 and a rotation adjustment component 32. The tilt adjustment component 31 is connected to the guide rod 2, and the rotation adjustment component 32 is connected to the tilt adjustment component 31. When the threading guide device moves inside the pipe, the base 1 and the guide rod 2 will flip under the guidance of the traction rope. For this reason, the rotation adjustment component 32 drives the guide rod 2 to rotate, so that the rotation axis of the guide rod 2 is parallel to the horizontal plane. The tilt adjustment component 31 drives the guide rod 2 to rotate upward. The guide rod 2 can stably achieve upward rotation at its front end, avoiding the phenomenon that the guide rod 2 rotates in other directions due to angular deviation, which would lead to threading failure, thus improving the threading success rate and operation efficiency.

[0055] Reference Figure 9 In this embodiment, the rotation adjustment member 32 includes a second motor 321, which is nested in the end of the base 1 facing the guide rod 2. The axis of the output shaft of the second motor 321 is collinear with the axis of the base 1. The output shaft of the second motor 321 is fixedly connected to the tilt adjustment member 31, so that the second motor 321 can guide the rod 2 to rotate around the axis of the base 1.

[0056] Reference Figure 9In this embodiment, the tilt adjustment member 31 includes a rotating support 311, a rotating shaft 312, and a driving member 33. The outer wall of the rotating support 311 is cylindrical. The output shaft of the second motor 321 is fixedly connected to the rear end of the rotating support 311. The rotating shaft 312 is rotatably inserted into the front end of the rotating support 311. The axial direction of the rotating shaft 312 is perpendicular to the axial direction of the rotating support 311. The guide rod 2 is fixedly connected to the rotating shaft 312 through a connecting part, so that the guide rod 2 can rotate around the rotating shaft 312.

[0057] Reference Figure 9 , Figure 10 The driving component 33 includes a first motor 331 and a bevel gear assembly 332. An installation space 333 is provided within the rotating support 311. The first motor 331 is fixedly installed within the installation space 333, and the axis of the output shaft of the first motor 331 is collinear with the axis of the rotating support 311. The bevel gear assembly 332 includes a first bevel gear 3321 and a second bevel gear 3322. The first bevel gear 3321 is coaxially fixed on the output shaft of the first motor 331, and the second bevel gear 3322 is coaxially fixed on the rotating shaft 312. The first bevel gear 3321 and the second bevel gear 3322 mesh. The first motor 331 drives the rotating shaft 312 to rotate via the first bevel gear 3321 and the second bevel gear 3322, achieving precise rotation control of the guide rod 2. Simultaneously, by replacing manual adjustment with motor drive, operational efficiency and accuracy are improved, ensuring a smoother threading process.

[0058] Reference Figure 2 , Figure 9 An elastic tube 5 is fitted onto both the guide rod 2 and the rotating support 311. In this embodiment, the elastic tube 5 is an elastic rubber tube, which adapts to the rotation of the guide rod 2 by its own elastic deformation. One end of the elastic tube 5 is embedded in the rotating support 311, and the other end is embedded in the guide rod 2, so that the outer wall of the elastic tube 5 is flush with the outer walls of the guide rod 2 and the rotating support 311. The elastic tube 5 encloses the rotating structure between the guide rod 2 and the base 1, which can effectively protect the connection structure between the rotating support 311 and the rotating shaft 312, preventing dust and impurities from entering, thereby improving the stability and service life of the rotation adjustment component 3. On the other hand, the elastic tube 5 can slide along the bottom of the downstream pipe connection end 71, preventing the hinge structure between the guide rod 2 and the base 1 from getting stuck in the downstream pipe connection end 71, making the wire guiding device move more smoothly in the pipe.

[0059] When the threading guide device moves to the misaligned part of the pipe, the second motor 321 drives the rotating support 311 to rotate around the axis of the base 1, making the axis of the rotating shaft 312 horizontal. Then, the first motor 331 is driven to rotate, which in turn drives the first bevel gear 3321 to rotate. The first bevel gear 3321 drives the second bevel gear 3322 to rotate, which in turn drives the rotating shaft 312 to rotate. The rotating shaft 312 drives the guide rod 2 to rotate upward, making the front end of the guide rod 2 higher than the bottom of the downstream pipe connection end 71. Then, the threading guide device continues to move forward, and the guide rod 2 guides the threading guide device to slide into the downstream pipe, ensuring that the threading guide device moves smoothly in the pipe.

[0060] In this embodiment, the first motor 331, the second motor 321, and the third motor 661 are all powered by battery modules, and their power supply and forward / reverse rotation are controlled by a wireless control system composed of a wireless communication module and a controller. In other embodiments, the motors can also be controlled by external power and control lines. This wiring device has through holes at the first motor 331, the second motor 321, and the third motor 661 for heat dissipation.

[0061] The implementation principle of the cable threading guide device in this application embodiment is as follows: the camera 41 moves with the cable threading guide device to monitor the internal condition of the pipeline in real time. Through the camera 41, it can be observed that the cable threading guide device moves to the misalignment point of the pipeline. The second motor 321 drives the rotating support 311 to rotate around the axis of the base 1, so that the axis of the rotating shaft 312 is horizontal. Then, the first motor 331 is driven to rotate. The first motor 331 drives the first bevel gear 3321 to rotate. The first bevel gear 3321 drives the second bevel gear 3322 to rotate. The second bevel gear 3322 drives the rotating shaft 312 to rotate. The rotating shaft 312 drives the guide rod 2 to rotate upward, so that the front end of the guide rod 2 is higher than the bottom of the downstream pipeline connection end 71. Then, the cable threading guide device continues to move forward. The guide rod 2 guides the cable threading guide device to slide into the downstream pipeline, improving the convenience of laying cables in the pipeline.

[0062] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
