Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable guiding structure technology, specifically a cable guiding structure for power construction. Background Technology
[0002] In high-altitude power line construction, cables need to be suspended from steel cables between two power towers by fixed frames at intervals. The steel cables provide support and spatial positioning for the cables. As a core piece of equipment to ensure the efficient and safe construction, maintenance and repair of power transmission lines, the performance of the cable guide structure directly determines the construction quality, work efficiency and operation and maintenance safety.
[0003] Traditional cable-laying methods rely on manual dragging of cables. When faced with long-distance spans and multiple cables being laid in parallel, the manpower consumption increases exponentially. It takes a long time to lay a single section of cable. In high-altitude operations, the relative positions of cables, steel cables, and fixed frames require multiple people to coordinate and adjust, making the operation cumbersome and posing high safety risks.
[0004] To address the aforementioned issues, we propose a power construction cable guiding structure. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a power construction cable guiding structure includes a hook 1 and a steel cable 2. The hook 1 is movably connected to the outside of the steel cable 2. A connecting post 3 is fixedly connected to the bottom of the hook 1. A first sliding frame 4 is rotatably connected to the bottom of the connecting post 3. A second sliding frame 5 is rotatably connected to one end of the bottom of the first sliding frame 4. A first pulley 6 is rotatably connected inside the first sliding frame 4. A second pulley 7 is rotatably connected inside the second sliding frame 5. A locking mechanism 8 is provided at one end of the first sliding frame 4 and the second sliding frame 5. An opening and closing arm 10 is hinged to the bottom of the hook 1. One end of the opening and closing arm 10 is rotatably connected to the inside of the hook 1. A limit ring 9 is fixedly connected to the top of the connecting post 3.
[0022] The process involves inserting the steel cable 2 into the hook 1, suspending the first sliding frame 4 and the second sliding frame 5 below the steel cable 2 via the connecting column 3. At this point, the sliding frames are in a closed and locked state by default. Then, a nylon rope with a rated load capacity greater than or equal to 1.5 times the self-weight of the cable is selected, and one end is securely tied to the lower part of the connecting column 3, allowing the rope to hang naturally to the ground operating area. Simultaneously, the nylon rope is inspected for damage and broken strands to ensure that its mechanical properties meet the standards.
[0023] Then unlock the locking mechanism 8, and the first and second sliding frames rotate outward to form an open cable accommodating space. Place the cable smoothly into the sliding frame, ensuring that the cable is embedded in the arc-shaped fitting groove of the first pulley 6 and the second pulley 7 (the curvature of the pulley groove matches the outer diameter of the cable, forcibly constraining the cable to be centered and avoiding wear from the groove). Finally, close the first sliding frame 4 and the second sliding frame 5.
[0024] Ground personnel pull the bottom of the nylon rope at a constant speed and with low impact. The tension is transmitted to the hook 1 through the connecting column 3. The driving device slides at a constant speed along the axis of the steel cable 2. The connecting column 3 and the first sliding frame 4 are rotatably connected to ensure that the sliding frame adapts to the slope of the steel cable during sliding. The cable moves forward by relying on the rolling friction of the pulley (the pulley rotates with the displacement of the cable, and the friction coefficient is ≤0.15, which greatly reduces the wear rate of the insulation layer).
[0025] When the device slides to the support spacing specified in the design drawings (e.g., 50m / span), temporarily anchor the nylon rope and suspend traction; use a special fixing frame (a ring-type clamp that is compatible with the steel cable) to secure the cable under the steel cable, check simultaneously, and after confirming that it meets the standard, unlock the nylon rope anchor and continue the guidance operation in the next section;
[0026] Furthermore, the bottom of the hook 1 is machined with a rotating groove 11, and the bottom end of the opening and closing arm 10 is rotatably connected to the inside of the rotating groove 11. A torsion spring 12 is provided inside the opening and closing arm 10.
[0027] When it is necessary to hang the hook 1 on the outside of the steel cable 2, first press the opening and closing arm 10 to retract the opening and closing arm 10 into the hook 1, and then put the steel cable 2 into the inside of the hook 1. When the steel cable 2 enters the inside of the hook 1, the opening and closing arm 10 will rebound and reset through the torsion spring 12, so that one end of the opening and closing arm 10 contacts the inner wall of the hook 1, thereby closing the hook 1.
[0028] Secondly, when the opening and closing arm 10 is in motion, one end of the opening and closing arm 10 will rotate along the inside of the rotating groove 11, and when the opening and closing arm 10 is fixed, the other end of the opening and closing arm 10 will be engaged in the inside of the slot 13.
[0029] Furthermore, the locking mechanism 8 includes a first connecting piece 801 and a second connecting piece 802. The first connecting piece 801 is fixedly connected to the outer side of the bottom end of the first sliding frame 4, and the second connecting piece 802 is fixedly connected to the outer side of the bottom end of the second sliding frame 5. A bolt 803 is provided on the top of the first connecting piece 801, and the bottom of the bolt 803 penetrates the interior of the first connecting piece 801 and the second connecting piece 802. A nut 804 is provided on the bottom of the second connecting piece 802, and the nut 804 is threadedly connected to the bottom of the bolt 803.
[0030] When it is necessary to put the cable into the first sliding frame 4 and the second sliding frame 5, rotate the nut 804 to disengage the nut 804 from the bottom of the bolt 803, so that the bolt 803 can be removed. Then, the second sliding frame 5 can be rotated to separate one end of the first sliding frame 4 and the second sliding frame 5, so that the cable can be placed between the first sliding frame 4 and the second sliding frame 5.
[0031] Furthermore, a movable shaft 15 is fixedly connected to one bottom end of the first sliding frame 4, and a movable groove 16 is machined to one top end of the second sliding frame 5. The movable shaft 15 is rotatably connected inside the movable groove 16. When the first sliding frame 4 and the second sliding frame 5 are opened and rotated, the first sliding frame 4 will drive the movable shaft 15 to move. The movable shaft 15 will move along the inside of the movable groove 16. A limit ring is provided at the bottom of the movable shaft 15, so that the first sliding frame 4 remains stable when rotating.
[0032] Working principle: The steel cable 2 is inserted into the hook 1, so that the first sliding frame 4 and the second sliding frame 5 are suspended below the steel cable 2 via the connecting column 3. Then, one end of the nylon rope is firmly tied to the lower part of the connecting column 3, allowing the rope to hang naturally to the ground operating area. Then, the locking mechanism 8 is unlocked, and the first and second sliding frames rotate and open outward to form an open cable receiving space. The cable is then smoothly placed into the sliding frame. Finally, the ground personnel pull the bottom end of the nylon rope at a uniform speed. The tension is transmitted to the hook 1 through the connecting column 3, and the drive device slides at a uniform speed along the axis of the steel cable 2. When the device slides to a fixed distance, a special fixing frame is used to secure the cable below the steel cable. The cable is checked simultaneously. The operation is simple and convenient.
[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
