Description

Technical Field

[0001] The utility model relates to the technical field of transmission line tools, in particular to a suspension clamp that prevents falling off. Background Art

[0002] Commonly available standardized products of suspension clamps currently retain the U-bolt style (usually called boat-shaped line clamps), which are composed of a hanging U-bolt, a line clamp hull made of malleable cast iron, and a pressing plate. Another type is the preformed suspension clamp. The suspension clamp is used to fix the conductor on the insulator string of a straight tower, or to hang the lightning protection wire on a straight tower. It can also be used to support the transposed conductor on a transposition tower and fix the jumper wire on a tension angle tower.

[0003] Although there are a large number and various types of transmission line suspension clamps on the existing market, the hanging ring joints of most transmission line suspension clamps will become loose and fall off, and there will be a phenomenon of screw friction and scraping under the influence of wind, resulting in the screw falling off, and further causing the suspension clamp to fall off.

[0009] A first hanging ring 13 is sleeved on the middle part of the outer side of the limiting rod 9, and the other end of the first hanging ring 13 is connected with a second hanging ring 14.

[0010] Further, each of the pressing rods 12 penetrates through the left fixing plate 6 and the right fixing plate 7, and anti-pulling-off plates 17 are connected to both the top end and the bottom end of the pressing rod 12. The anti-pulling-off plate 17 at the bottom end abuts against the first clamping block 11 but is not connected thereto.

[0011] Further, the limiting groove 5 is of a "T" - shaped structure, including a vertical sliding groove and a horizontal limiting groove.

[0012] Further, limiting blocks 16 are arranged on both sides of the first clamping block 11. The limiting blocks 16 are arranged in the upper middle part of the first clamping block 11, and the distance from the limiting blocks 16 to the bottom of the first clamping block 11 is equal to the height of the horizontal limiting groove.

[0025] Embodiment

[0026] As Figure 1 shown, the present invention provides an anti-dropping suspension clamp, which includes a left clamping ring 1 and a right clamping ring 3. Rubber pads are provided on the inner walls of the left clamping ring 1 and the right clamping ring 3, which can play a protective function and prevent the cable from being damaged.

[0027] The bottom ends of the left clamping ring 1 and the right clamping ring 3 are rotatably connected through a rotating shaft 2. The left clamping ring 1 and the right clamping ring 3 can freely rotate and open under the action of the rotating shaft 2. Through the rotating shaft 2, the left clamping ring 1 and the right clamping ring 3 can be conveniently opened and closed normally, which is convenient for placing the power transmission line.

[0028] The top end of the left clamping ring 1 is fixedly connected with a left fixing plate 6, and the top end of the right clamping ring 3 is fixedly connected with a right fixing plate 7. A screw 8 is inserted through the left fixing plate 6 and the right fixing plate 7. After the power transmission line is placed, the clamp is preliminarily fixed with the screw 8;

[0029] Through grooves are opened at positions close to the upper part of the left fixing plate 6 and the right fixing plate 7, and a limiting rod 9 is inserted through the two through grooves. The through grooves match the limiting rod 9, and the limiting rod 9 is slidably connected with the through grooves. The clamp is secondarily fixed through the limiting rod 9, and the sliding setting facilitates the fixing or pulling of the limiting rod 9;

[0030] As Figure 2As shown in the figure, limiting grooves 5 are provided at positions corresponding to the left fixing plate 6 and the right fixing plate 7 on the limiting rod 9. The limiting grooves 5 are of a "T" - shaped structure, including a vertical sliding groove and a horizontal limiting groove. A first spring 10 is arranged in each limiting groove 5. The lower end of the first spring 10 is connected to the limiting rod 9, and the upper end of the first spring 10 is connected to a first clamping block 11. The first clamping block 11 matches the limiting groove 5 and is slidably arranged in the limiting groove 5. Limiting blocks 16 are arranged on both sides of the first clamping block 11. The limiting blocks 16 are arranged in the upper middle part of the first clamping block 11, and the distance from the limiting blocks 16 to the bottom of the first clamping block 11 is equal to the height of the horizontal limiting groove.

[0031] Above each first clamping block 11, a pressing rod 12 is arranged. The height of the pressing rod 12 is greater than the height of the horizontal limiting groove so as to completely press the first clamping block 11 into the limiting groove. Each pressing rod 12 penetrates through the left fixing plate 6 and the right fixing plate 7 respectively. Anti - pulling - off plates 17 are connected to the top end and the bottom end of the pressing rod 12. The anti - pulling - off plate 17 at the bottom end abuts against the first clamping block 11 but is not connected to it. By means of the pressing rod 12, the length of the first clamping block 11 extending into the limiting groove can be controlled, and the first clamping block 11 can be pressed by the pressing rod 12 to take out the limiting rod 9.

[0032] A first hanging ring 13 is sleeved in the middle of the outer side of the limiting rod 9. The other end of the first hanging ring 13 is connected to a second hanging ring 14. The second hanging ring 14 is of a "U" - shaped structure. A fixing rod 15 with detachable connection is horizontally arranged on the upper part of the second hanging ring 14. Specifically, the fixing rod 15 penetrates through both sides of the second hanging ring 14, and the fixing rod 15 is threadedly connected to the second hanging ring 14. Both the first hanging ring 13 and the second hanging ring 14 are made of a relatively hard steel material. By using a relatively hard steel material, its service life can be effectively extended, and the stability of the wire clamp can be further improved.

[0033] The working principle of the utility model is as follows: First, the power transmission line is fixed on the wire clamp by the left clamping ring 1 and the right clamping ring 3. After the position of the power transmission line is fixed, the wire clamp is preliminarily fixed by the screw 8. Then the limiting rod 9 is passed through the left fixing plate 6 and the right fixing plate 7. When the first clamping block 11 reaches the designated position, the first clamping block 11 will pop out of the limiting groove and be clamped in the fixing plate, that is, the secondary fixing of the wire clamp is completed. Then the second hanging ring 14 is moved to the position where it needs to be fixed, and the fixing rod 15 is used for fixed installation. It will not be affected by the wind, greatly improving the stability of the hanging wire clamp, and the hanging wire clamp will not fall off easily.

[0034] It should be noted that all components in the present utility model are common standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or obtained through conventional experimental methods. At the same time, the standard parts used in the present utility model can be purchased from the market. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and no specific description will be made here.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
