Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically a wire clamp for outdoor power transmission lines. Background Technology

[0002] The wire clamp used in outdoor power transmission lines is a key electrical hardware. It is mainly used to connect and fix wires to ensure the stability and safety of power transmission. It is particularly suitable for connecting small and medium cross-section aluminum stranded wire or steel-cored aluminum stranded wire, as well as steel stranded wire of overhead lightning protection wire in positions where they are not subjected to tension. It is also often used for jumper connections of non-straight towers. The wire clamp usually uses two clips to hold the wire on both sides and is locked with bolts and nuts to connect the two wires.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] Please see Figure 1-5 In this embodiment of the utility model, an outdoor power transmission line clamp includes a fixing base 100, a mounting base 200, a first fixing component 300, a second fixing component 400, a first threaded rod 500, a second threaded rod 600, a third threaded rod 700, and a fourth threaded rod 800. The top surface of the fixing base 100 is symmetrically provided with a first sliding groove 110 and a second sliding groove 120. The mounting base 200 is disposed between the first sliding groove 110 and the second sliding groove 120. The bottom surface of the mounting base 200 is fixedly connected to the top surface of the fixing base 100. The device has two internal cavities. Fixing component 1 300 includes an arc-shaped clamping block 1 310 and an arc-shaped clamping block 2 320. Support plates 1 311 and 2 321 are fixedly connected to the bottom surfaces of arc-shaped clamping blocks 1 310 and 2 320, respectively. The bottoms of support plates 1 311 and 2 321 are slidably connected to the interior of the sliding groove 2 120. Fixing component 2 400 includes an arc-shaped clamping block 3 410 and an arc-shaped clamping block 420. Support plates 311 and 4 420 are fixedly connected to the bottom surfaces of the arc-shaped clamping blocks 3 410 and 4 420, respectively. Plate 3 411 and support plate 421 are slidably connected to the inside of the slide groove 110 at their bottoms. The end of threaded rod 500 away from the arc-shaped clamping block 3 410 is rotatably connected to the inner wall of one of the cavities inside the mounting base 200. A sleeve 510 is screwed onto the outer wall of threaded rod 500. The other end of sleeve 510 passes through the side wall of mounting base 200 and is fixedly connected to the side wall of arc-shaped clamping block 3 410. An adjusting knob 52 is sleeved and fixedly fixed onto the outer wall of threaded rod 500. 0. The end of threaded rod 2 600 away from arc-shaped clamp 1 310 is rotatably connected to the inner wall of another cavity inside the mounting base 200. The outer wall of threaded rod 2 600 is screwed with sleeve 2 610. The other end of sleeve 2 610 passes through the side wall of mounting base 200 and is fixedly connected to the side wall of support plate 1 311. The outer wall of threaded rod 2 600 is sleeved and fixedly fitted with adjustment knob 2 620. The ends of sleeve 1 510 and sleeve 2 610 located inside the cavity are respectively fixedly connected to limit block 1 511 and limit block 2 611.

[0030] Specifically, during use, maintenance personnel only need to place the two wires on the fixing components 300 and 400 above the fixing base 100, respectively. Adjustment knob 520 can be rotated according to the distance between the two wires. Adjustment knob 520 drives the threaded rod 500 to rotate, causing the sleeve 510 to move along the outer wall of the threaded rod 500 as it rotates. This moves the arc-shaped clamping block 410, and the support plate 411 moves along the slide groove 110. Following this procedure, adjustment knob 62 is then rotated. 0. Make the arc-shaped clamp 310 and arc-shaped clamp 1 310 contact with the two wires respectively. Then slide the support plate 421 and support plate 2 321 along the slide groove 110 and slide groove 2120 respectively, so that the arc-shaped clamp 420 and arc-shaped clamp 2 320 also contact the two wires respectively. The arc-shaped clamp 1 310 and arc-shaped clamp 2 320 tightly clamp the first wire, and the arc-shaped clamp 3 410 and arc-shaped clamp 4 420 tightly clamp the second wire. This wire clamp can adapt to wires of different sizes and does not require changing to wire clamps of different sizes.

[0031] like Figure 3-4 As shown, in this embodiment, a threaded rod 800 is rotatably connected inside the slide groove 2 120. One end of the threaded rod 800 away from the fixed seat 100 extends out of the side wall of the fixed seat 100 and is fixedly connected to an adjusting knob 810. The side wall of the support plate 421 has a threaded hole 422 that is screwed into the outer wall of the threaded rod 700. The side wall of the support plate 321 has a threaded hole 322 that is screwed into the outer wall of the threaded rod 800. The side wall of the support plate 311 has a round hole 412 that is slidably sleeved with the outer wall of the threaded rod 700. The side wall of the support plate 311 has a round hole 312 that is slidably sleeved with the outer wall of the threaded rod 800.

[0032] In this embodiment, rotating the adjustment knob 3 710 causes the threaded rod 3 700 to rotate, allowing the support plate 4 421 to slide along the outer wall of the threaded rod 3 700 within the slide groove 1 110. This changes the distance between the arc-shaped clamping block 4 420 and the arc-shaped clamping block 3 410, enabling them to clamp one of the wires. Rotating the adjustment knob 4 810 causes the threaded rod 4 800 to rotate, allowing the arc-shaped clamping block 1 310 and the arc-shaped clamping block 2 320 to clamp the other wire.

[0033] like Figure 1 and Figure 5As shown, in this embodiment, an upper cover plate 900 is included. Two connecting plates 910 are symmetrically fixed on the inner top surface of the upper cover plate 900. The bottom surfaces of the two connecting plates 910 are in contact with the top surface of the fixing base 100. The bottom surfaces of the two connecting plates 910 are provided with mounting holes 3 911. The bottom ends of the upper cover plate 900 on both sides are provided with mounting holes 4 920. The top surface of the fixing base 100 is provided with mounting holes 2 140 at positions corresponding to mounting holes 3 911. The top surface of the fixing base 100 is provided with mounting holes 130 at positions corresponding to mounting holes 4 920.

[0034] In practice, after the two wires are clamped and fixed by fixing component 1 300 and fixing component 2 400 respectively, the upper cover plate 900 is placed on top of them, so that mounting hole 4 920 corresponds to mounting hole 1 130 and mounting hole 3 911 corresponds to mounting hole 2 140. The upper cover plate 900 and the fixing base 100 are fixed together by screws or bolts, so that the upper cover plate 900 covers the two wires and reduces the corrosion and damage of the wires by the external environment.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
