Description

Technical Field

[0001] This invention belongs to the field of cable technology, specifically a fast-access bypass cable. Background Technology

[0002] Current cable laying and retrieval operations typically rely heavily on manual labor, which is not only inefficient but also particularly inconvenient in scenarios requiring rapid response, such as emergency repairs or temporary power supply. Traditional cable laying methods require workers to manually stretch and wind cables, which is not only time-consuming and labor-intensive but also carries the risk of cable tangling or damage due to improper operation. Furthermore, during cable connection to bypass lines, traditional plug-in or bolt-fastening methods are not only time-consuming but also require power outages in some cases, posing a challenge to the continuity and stability of power supply. Additionally, existing bolt-type cables are not convenient for quick connection to bypass lines, further increasing connection time. Summary of the Invention

[0003] The purpose of this invention is to provide a fast-access bypass cable to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a quick-access bypass cable, comprising a base and a cable, wherein an insulating rod for hanging is fixedly connected to one end of the cable, and a threaded joint is fixedly connected to the end of the insulating rod away from the cable, and a threaded sleeve is threadedly connected to the end of the threaded joint away from the insulating rod, and an access mechanism for quick access to the bypass line is fixedly connected to the end of the threaded sleeve away from the threaded joint.

[0005] The access mechanism includes a hook, and the hook is provided with a torsion spring for automatic reset. At the same time, a limiting gripper for limiting the hanging object is fixed to the torsion spring. A driven spring is fixed to the limiting gripper, and the end of the driven spring away from the limiting gripper is fixed to the hook. The hook is provided with an arc groove for bearing the hanging object.

[0006] As a further preferred embodiment of this technical solution: the two ends of the base are fixedly connected to brackets, and a support plate is fixedly connected to the end of a set of brackets away from the base. A winding and unwinding mechanism for winding and unwinding cables is installed on the support plate.

A reel frame is fixedly connected to the end of the drive shaft away from the motor. The cable is installed on the reel frame. At the same time, the end of the reel frame away from the drive shaft is rotatably connected to the bracket away from the motor.

[0007] As a further preferred embodiment of this technical solution: a support rod is fixedly connected to the bottom of the base, and a caster wheel is provided at the end of the support rod away from the base for moving the device;

[0008] As a further preferred embodiment of this technical solution: the two ends of the bracket are provided with sliding grooves, and a hydraulic rod is fixedly connected in the sliding grooves. At the same time, the telescopic end of the hydraulic rod is fixedly connected to a base frame for supporting the stabilizing device.

[0009] As a further preferred embodiment of this technical solution: a slider is slidably connected to a slide groove on one end of the bracket away from the hydraulic rod, and a connecting rod for limiting the lifting and lowering of the base frame is fixedly connected to the end of the slider away from the slide groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In this invention, the access mechanism adopts a design that combines a hook with a torsion spring and a limit gripper, which can automatically reset and lock after being hooked to the target line, ensuring a firm and reliable connection. Furthermore, at the cable connection end, the traditional plug-in or bolt fastening method is abandoned, and a self-developed hook-type cable head structure is adopted. Through the spring buckle and anti-drop locking device, the live connection can be completed by one hand, which significantly shortens the wiring time.

In this invention, the cable can be quickly wound up and down by means of a winding and unwinding mechanism, including a motor or manual turntable, a drive shaft, a reel frame and a cable, which significantly improves the efficiency of cable laying and recycling. It not only saves manpower but also increases the speed of operation. It is particularly suitable for emergency repairs, temporary power supply and other scenarios. At the same time, the winding and unwinding mechanism automatically triggers limit protection after the cable is fully unwound to avoid the risk of entanglement or pulling caused by manual operation.

[0014] 3. In this invention, by setting up a cable connection device, multiple cables can be connected in series to meet the requirements of different bypass distances. Attached Figure Description

[0027] Example 1:

[0028] Please see Figures 1-10 As shown, the present invention provides a technical solution: a quick-access bypass cable, including a base 1 and a cable 44. One end of the cable 44 is fixedly connected to an insulating rod 5 for hanging, and the end of the insulating rod 5 away from the cable 44 is fixedly connected to a threaded joint 6. At the same time, the end of the threaded joint 6 away from the insulating rod 5 is threadedly connected to a threaded sleeve 7. The end of the threaded sleeve 7 away from the threaded joint 6 is fixedly connected to an access mechanism 8 for quick access to the bypass line. At the same time, both ends of the cable 44 are provided with access mechanisms 8 for hanging, thereby enabling double-sided hanging.

[0029] Secondly, the base 1 is provided with a grounding hole for setting a grounding wire. At the same time, the port of the cable 44 can be connected to the cable 44 connector 17, which can flexibly increase the line length. The cable 44 is connected to the threaded groove 18 on the connector 17.

[0030] The access mechanism 8 includes a hook 81, and the hook 81 is provided with a torsion spring 82 for automatic reset.

[0031] like Figure 1 As shown: The insulating rod is equipped with a rain cover to prevent electric shock;

[0032] In this embodiment, specifically: the two ends of the base 1 are fixedly connected to the brackets 2, and the end of the brackets 2 away from the base 1 is fixedly connected to the support plate 3. The support plate 3 is equipped with a winding mechanism 4 for winding and unwinding the cable 44. The winding mechanism 4 includes a motor 41, and the motor 41 is fixedly connected to the support plate 3. At the same time, the output end of the motor 41 is fixedly connected to the drive shaft 42. The end of the drive shaft 42 away from the base 1 is fixedly connected to the reel frame 43. The cable 44 is installed on the reel frame 43. At the same time, the end of the reel frame 43 away from the drive shaft 42 is rotatably connected to the bracket 2 away from the motor 41. The two sides of the cable 44 are attached to the two sides of the reel frame 43. At the same time, the reel frame 43 is provided with isolation columns between every two turns of the cable 44 for the regular winding and unwinding of the cable 44.

[0033] In this embodiment, specifically: a support rod 9 is fixedly connected to the bottom of the base 1, and a universal wheel 10 for driving the device to move is provided at the end of the support rod 9 away from the base 1. Furthermore, there are four sets of support rods 9 and universal wheels 10, and the four sets of support rods 9 and universal wheels 10 are evenly distributed at the bottom of the base 1.

[0034] Furthermore, the caster wheel 10 comes with a built-in brake assembly to prevent the entire device from shaking.

[0035] In this embodiment, specifically: the two ends of the bracket 2 are provided with sliding grooves 11, and a hydraulic rod 12 is fixedly connected in the sliding groove 11. At the same time, the telescopic end of the hydraulic rod 12 is fixedly connected to a base frame 13 for supporting the stabilizing device. The distance that the base frame 13 descends is lower than the position of the universal wheel 10 on the ground, thus pushing the universal wheel 10 off the ground.

[0036] In this embodiment, specifically: a slider 16 is slidably connected to a slide groove 11 on a set of brackets 2 at the end away from the hydraulic rod 12, and a connecting rod 15 for limiting the lifting and lowering of the base frame 13 is fixedly connected to the end of the slider 16 away from the slide groove 11. At the same time, a square hole 14 is provided on the base 1, and the square hole 14 passes through the hydraulic rod 12 and the connecting rod 15.

[0037] In this embodiment, specifically: a connector 17 is sleeved inside the insulating rod 5, and the two ends of the connector 17 are provided with threaded grooves 18 for connecting cables 44. At the same time, the two ends of the inner side of the connector 17 are respectively fixed with a connecting block 19 and a locking post 25. The connecting block 19 is provided with a guide groove 20, and the two ends of the guide groove 20 are respectively fixed with an internal thread plate 21. At the same time, a threaded rod 22 is threaded through the internal thread plate 21. A clamping claw 23 for clamping the locking post 25 is fixed on the threaded rod 22. At the same time, the locking post 25 is provided with a locking groove 26, and the clamping claw 23 is clamped in the locking groove 26.

[0038] Working principle or structural principle: First, when it is necessary to connect cable 44 to a broken object in a kilovolt power distribution system, the external device can be moved aside by using casters 10. Then, the hydraulic rod 12 is activated. The telescopic end of the hydraulic rod 12 drives the base frame 13 to descend, lifting the casters 10 and stabilizing the external device. Then, the motor 41 is activated. The output end of the motor 41 drives the drive shaft 42 to rotate. The rotation of the drive shaft 42 drives the reel frame 43 to rotate, releasing cable 44. Then, the threaded sleeve 7 is rotated to connect to the threaded connectors 6 at both ends of cable 44. The access mechanism 8 is installed at both ends of cable 44. Finally, the access mechanism 8 can be hung on the broken object by using the insulating rod 5. When the hook 81 is hung on the target line, the torsion spring 82 drives the limit grip 83 to automatically reset and lock, ensuring a firm connection. At the same time, the arc groove 85 supports the hung object to prevent slippage, completing the rapid connection to the bypass power system.

[0039] Example 2:

[0040] like Figures 6-7 As shown: A threaded sleeve 7 is installed on one side of the hook 81 for the insertion of the insulating rod 5. At the same time, the drive end of the winding mechanism 4 can be replaced with a turntable to manually drive the reel frame 43 to rotate, so as to prevent the reel frame 43 from being driven when there is no power.

[0041] 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.
