Description

Technical Field

[0001] The utility model relates to the field of conductor fixing fixtures, in particular to a conductor fixing fixture for a power tower. Background Art

[0002] Power tower conductor clamps are specialized devices used in power systems, particularly on transmission line towers, to secure and suspend conductors. These clamps stabilize conductors against wind, weight, and other external factors, preventing them from slipping or vibrating, thereby ensuring safe and reliable power transmission. Depending on the conductor type, insulator type, and specific line conditions, clamps include suspension clamps, release clamps, and tension clamps.

[0003] Tension clamps are primarily used to secure and tighten conductors, ensuring their stability on towers. They withstand conductor tension, preventing slippage or vibration caused by external forces or environmental factors, thereby ensuring safe and reliable power transmission. Strain clamps are available in two types: reusable and disposable. The former, such as bolt-type and wedge-type clamps, are reusable, while the latter, once secured to the conductor, cannot be removed.

[0004] Bolt-type tension clamps have a wider range of applications, but they require at least two people to work together to secure the conductor. After the conductor is correctly positioned, one person holds the main conductor head and the clamp tightly, while the other holds the lead wire and slowly presses it down to secure it in place. The clamps are then installed and tightened sequentially from the hanging side toward the outlet to secure the lead wire. Finally, the tension clamps are installed. This traditional tension clamp installation method is difficult for one person to perform, resulting in low efficiency. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 As shown, a power tower conductor fixing fixture includes a tension clamp consisting of a hanging portion 1 and an outlet portion 2. Several connecting bases 4 are evenly distributed at the bottom of the outlet portion 2. Each connecting base 4 is equipped with a U-bolt 5 for fixing the conductor. The hanging portion 1 and the outlet portion 2 are integrally formed components, and a hanging connecting bolt 3 is also provided at the top of the hanging portion 1. The connecting bases 4 and the outlet portion 2 are also integrally formed components. The U-bolts 5 are connected to the connecting bases 4 with their openings facing downward, and each U-bolt 5 is equipped with a resilient pressing block 6.

[0020] like Figure 2 As shown, a pre-stressing structure 7 is installed between adjacent connecting bases 4. One end of the pre-stressing structure 7 is rotatably connected to one side of the outlet portion 2, and the other end is connected to the other side of the outlet portion 2 through a snap-fit structure. The main body of the pre-stressing structure 7 is an elastic and retractable arc-shaped hoop structure.

[0021] In this embodiment, the pre-stressing structure 7 includes a pair of shaft seats 8 and clamping seats 9, which are fixed and symmetrically welded on both sides of the outlet portion 2, wherein the shaft seat 8 provides a rotational connection for the pre-stressing structure 7, and the clamping seat 9 provides a snap connection. The arc hoop structure of the pre-stressing structure 7 is divided into an arc tube 12 at the tail and an arc rod 13 at the head. The arc tube 12 and the arc rod 13 are movably connected. The other end of the arc tube 12 is fixedly connected to a rotating shaft 10, which is rotatably installed in the shaft seat 8. The other end of the arc rod 13 is fixedly connected to a clamping column 11, which can be flipped and clamped into the semicircular clamping seat 9. An arc spring 14 is provided inside the arc tube 12. One end of the arc spring 14 is fixedly connected to the rotating shaft 10, and the other end is fixedly connected to the end of the arc rod 13. The arc rod 13 is normally retracted in the arc tube 12.

[0022] In the actual operation of fixing the wire, first measure the length, use a marker to draw a clear wire clamp installation position on the wire, then use aluminum tape to wrap it tightly along the twisting direction of the wire, and leave a gap at the installation position mark for easy inspection. Then align the mark with the position of the suspension connecting bolt 3 on the suspension part 1, hold the main wire head tightly in the suspension part 1 with one hand, and press the lead head down along the groove of the outlet part 2 with the other hand. After confirming that the length is correct, do not relax the hand holding the lead head, and slowly turn the pre-stressing structure 7 over with the other hand, that is, use the free hand to pinch the force-applying head 15 and flip it, flip the arc tube 12 and the arc rod 13 and press them onto the lead head of the wire, then press the force-applying head 15 down with force, pull the arc rod 13 out of the arc tube 12 until the clamping column 11 at the head of the arc rod 13 is stuck in the clamping seat 9, at this time, the arc spring 14 inside the arc tube 12 tightens the arc rod 13 under the action of tension, thereby completing the pre-stressing of the lead head, and thus operate the pre-stressing structure 7 one by one in the order from the suspension part 1 to the outlet part 2 to complete the pre-stressing of the lead head. The lead head can be effectively prevented from shifting, thereby facilitating the subsequent installation of the U-bolt 5 to achieve complete fixation of the lead head. The entire operation can be completed by a single person, greatly improving efficiency.
