Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware products, in particular to an anti-loosening UT wire clamp. Background Art

[0002] In power lines, each pole or tower used to erect power lines usually requires two to eight inclined steel strands. One end of the steel strand is fixed to the upper or middle part of the pole or tower, and the other end is fixed to the ground to ensure that the pole or tower remains upright and does not tilt when subjected to external forces, thereby ensuring the safe operation of the power lines. There must be at least one wire tie fitting in the middle of the inclined steel strands. Adjusting the wire tie fitting can balance the forces around the pole or tower. The most common wire tie fitting is the UT wire clamp. The function of the UT wire clamp is to adjust the tension of the steel strands of the pole or tower to balance the forces.

[0003] After searching, in the prior art, a Chinese patent with patent application number CN201821059721.X discloses a UT wire clamp, which belongs to the technical field of electric power hardware products and is used to solve the problem that after a period of time, the steel strands of the existing UT wire clamps become longer at high temperatures due to thermal expansion and contraction, so that the UT wire clamps cannot always ensure that the poles are evenly stressed during actual use, and there is a risk of tipping over. It includes a U-shaped pull rod and a wire clamp body, and the wire clamp body is symmetrically provided with hanging ears on both sides, and the wire clamp body is provided with a through cavity in the vertical direction, and the two sides of the cavity are provided with through wire pulling holes in the vertical direction, and an elastic component is provided in the cavity; the elastic component includes a top block, a spring and a bottom block, the top block is fixedly connected to the side wall of the cavity of the wire clamp body, the top of the spring is connected to the top block, the bottom of the spring is connected to the bottom block, and the bottom block is movably connected to the cavity; the hanging ears are provided with through holes, and the two ends of the U-shaped pull rod pass through the hanging ears on both sides of the wire clamp body respectively, and are locked by adjusting nuts; but the following defects still exist:

[0004] (1) The UT wire clamps in the prior art have a poor fixing effect on the steel strands. The steel strands are prone to loosening during use, resulting in poor stability.

[0005] When the UT wire clamp in the prior art is in use, the force of the wire clamp is likely to act directly on the nut, which may cause the nut to loosen, resulting in a poor loosening effect of the UT wire clamp.

[0006] Therefore, we make improvements to this problem and propose a UT wire clamp that prevents loosening. Utility Model Content
