Description

Technical Field

[0001] This invention relates to the field of power facilities, and in particular to a guide rope winding device for overhead transmission lines. Background Technology

[0002] In the traditional process of laying power facilities, due to the large span between two adjacent towers, and the presence of obstacles such as valleys, crops, dense forests or buildings between the towers, a normal cable laying channel cannot be formed regardless of the type of obstacle.

[0003] Therefore, current technology typically uses flight equipment to deploy the guide rope, which then pulls the conductor to move, thus achieving the erection of the conductor. Currently, Dyneema rope is commonly used as the guide rope, and a traction machine and a winding reel are used in conjunction to achieve the winding operation.

[0004] During the use of the guide rope, the inside of the guide rope often breaks or is damaged, but the nylon outer skin remains intact. Only the damaged area has a dented groove, making it difficult to detect the defect in the guide rope in time, which affects the safety of subsequent use and needs to be improved. Summary of the Invention

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, a guide rope winding device for overhead transmission lines includes a base 1, a traction machine 2, a winding reel 3, a support frame 4, a detection ring 5, a detection rod 6, a detection head 7, and a marking mechanism 8.

[0036] like Figure 1 As shown, base 1 is horizontally positioned on the ground, and traction machine 2 is located at the front end of base 1, tensioning and pulling the guide rope. Reel 3 is located at the rear end of base 1, winding the guide rope.

[0037] like Figure 1 As shown, the support frame 4 is located in the middle of the base 1, between the traction machine 2 and the winding reel 3. A cleaning tube 41 is provided on the support frame 4, which is embedded in the detection ring 5. The cleaning tube 41 is for the guide rope to pass through and abuts against the outer wall of the guide rope.

[0038] like Figure 1 As shown, the detection ring 5 is mounted on the support frame 4 and is used for threading the guide rope. The detection rods 6 are evenly distributed on the detection ring 5, and their length direction is the same as the diameter direction of the detection ring 5.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, the detection head 7 is vertically slidably connected to the detection rod 6, and its end position abuts against the outer wall of the guide rope. A spring 61 is provided inside the detection rod 6 to control the outward sliding of the detection head 7. A displacement sensor 62 is provided between the detection rod 6 and the detection head 7.

[0040] like Figure 1 , Figure 4 As shown, the marking mechanism 8 is mounted on the support frame 4 and located behind the detection ring 5, and is used to mark the outer wall of the guide rope.

[0041] like Figure 1, Figure 4 As shown, the marking mechanism 8 includes a fixed frame 81, sliders 82, marking blocks 83, and a drive mechanism 9. The fixed frame 81 is vertically mounted on the support frame 4, and a pair of sliders 82 are vertically slidably connected to the fixed frame 81. The marking blocks 83 are horizontally mounted and located above and below the guide rope.

[0042] like Figure 1 , Figure 4 As shown, the drive mechanism 9 is used to control the relative sliding of the slider 82. The drive mechanism 9 includes a bidirectional lead screw 91, a reducer 92, and a signal receiving and control component 93.

[0043] like Figure 1 , Figure 4 As shown, the bidirectional lead screw 91 is vertically rotatably connected to the fixed frame 81 and threadedly connected to the slider 82. The reducer 92 is used to control the rotation of the bidirectional lead screw 91, and the signal receiving and control component 93 is used to receive the signal from the displacement sensor 62 and to open and close the reducer 92.

[0044] When it is necessary to wind up the guide rope, the traction machine 2 is used to pull the guide rope, and then the winding reel 3 is used to wind the guide rope. During this process, the guide rope first passes through the cleaning pipe 41, and the cleaning pipe 41 is used to scrape away debris from the outer wall of the guide rope.

[0045] Then the guide rope passes through the detection ring 5, and the detection heads 7 on each detection rod 6 abut against the outer wall of the guide rope, while the spring 61 is in a compressed state. Subsequently, as the guide rope is wound up, the detection heads 7 slide on the outer wall of the guide rope. If there is a break or damage inside the guide rope, the diameter of the damaged position of the guide rope becomes smaller. When the detection head 7 is located at the damaged position, the spring 61 will extend and push the detection head 7 to slide outward, and the displacement sensor 62 will change, transmitting the data to the signal receiving and control component 93.

[0046] Subsequently, the signal receiving and control component 93 controls the reducer 92 to work. At this time, the reducer 92 controls the bidirectional lead screw 91 to rotate. The bidirectional lead screw 91 drives the slider 82 to slide relative to each other. The slider 82 drives the marking block 83 to move synchronously, so that the marking block 83 clamps the guide rope. As the guide rope moves, it will make a mark on the guide rope, marking the position in front of the defect, thus completing the defect detection and marking of the guide rope.

[0047] Therefore, by setting up a detection mechanism between the traction machine 2 and the winding reel 3, the defect detection of the guide rope can be realized, and the defect location can be marked. This facilitates the accurate detection and evaluation of the performance of the defect location in the later stage, ensuring the safety of subsequent use.

[0048] like Figure 4 , Figure 5As shown, the marking block 83 includes a bottom shell 84, a marking head 85, and an elastic member 86. The bottom shell 84 is open, the marking head 85 is slidably connected to the bottom shell 84, and the elastic member 86 is disposed between the bottom shell 84 and the marking head 85.

[0049] like Figure 4 , Figure 5 As shown, the marking head 85 includes an ink cartridge 87 and a fiber head 88. The ink cartridge 87 contains marking ink and has a slot 871. The bottom wall of the slot 871 has an outlet hole 872. The fiber head 88 is embedded in the slot 871, and the ink cartridge 87 has a protective cover 89 covering the fiber head 88.

[0050] When marking is required on the guide rope, the protective cover 89 is opened first. When the marking block 83 clamps the guide rope, the elastic element 86 will be compressed, and the marking head 85 will press against the outer wall of the guide rope. As the guide rope moves, the fiber head 88 can apply the marking ink in the ink cartridge 87 to the outer wall of the guide rope to achieve stable marking, ensure the clarity of the marking line, and facilitate the subsequent detection and evaluation of the performance of the defect location.

[0051] like Figure 1 , Figure 2 , Figure 3 As shown, the detection rod 6 is slidably connected to the detection ring 5 along the diameter direction of the detection ring 5, and the detection ring 5 is provided with a control mechanism 63 for controlling the sliding of the detection rod 6.

[0052] like Figure 2 , Figure 3 As shown, the control mechanism 63 includes a control ring 64, a worm gear 65, and a worm 66. The control ring 64 is rotatably connected to the detection ring 5. A guide rod 67 is horizontally arranged on the outer wall of the detection rod 6, and a guide hole 68 is inclinedly arranged on the detection ring 5 for the guide rod 67 to slide. The worm gear 65 is disposed on the outer wall of the control ring 64, and the worm 66 is vertically rotatably connected to the detection ring 5 and meshes with the worm gear 65. Friction tubes 69 are provided on the detection ring 5 to clamp the two ends of the worm 66, realizing friction locking after the worm 66 rotates.

[0053] When it is necessary to wind and inspect guide ropes of different diameters, the worm gear 66 is controlled to rotate. At this time, the worm gear 66 drives the worm wheel 65 and the control ring 64 to rotate. With the cooperation of the guide rod 67 and the guide hole 68, the rotation of the control ring 64 can control the vertical sliding of the detection rod 6, so that the end positions of the detection rod 6 are closer or farther away from each other, thereby realizing the adjustment of the distance between multiple detection heads 7, meeting the winding and inspection requirements of different diameters, and improving practicality.

[0054] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
