Description

Technical Field

[0001] The utility model relates to the technical field of tension wire clamps, in particular to a novel electric power tension wire clamp. Background Art

[0002] Strain clamps refer to hardware used to fix conductors to withstand conductor tension and hang conductors on tension strings or pole towers. Strain clamps can be roughly divided into two categories according to their structures and installation conditions. The first category: strain clamps must withstand the full tensile force of conductors or lightning conductors. The clamp gripping force must not be less than 90 of the rated tensile force of the installed conductors or lightning conductors, but they are not conductors. This type of clamp can be removed after the conductors are installed and used separately. This type of clamp includes bolt-type strain clamps and wedge-type strain clamps. The second category: in addition to bearing the full tensile force of conductors or lightning conductors, strain clamps also serve as conductors. Therefore, once installed, these clamps cannot be removed. They are also called dead clamps. Since they are conductors, the installation of the clamps must comply with the relevant installation operating procedures and be carried out carefully.

[0026] like Figure 1-3 As shown, this embodiment proposes a novel electric power tension clamp, comprising a first mounting ring 100 and a second mounting ring 102 connected to the side wall of the first mounting ring 100 through a fixing bolt 101, the side walls of the first mounting ring 100 and the second mounting ring 102 are both connected with an adaption component for adjusting the distance of the wires according to on-site needs, wherein the adaption component comprises an adjustment screw 103 rotatably connected to the outer wall of the first mounting ring 100, and a slide rod 104 is fixedly connected to the outer wall of the first mounting ring 100, and the slide rod 104 is connected to the adjustment screw 103. Two groups are symmetrically arranged on the central axis, and the outer wall of the adjusting screw 103 is threadedly connected with a moving block 105, and the moving block 105 is also slidably connected to the slide rod 104. The top wall of the moving block 105 is fixedly connected with a wire supporting component for installing the wires, and the inner walls of the first mounting ring 100 and the second mounting ring 102 are connected with an anti-fall component for improving the stability of the first mounting ring 100 and the second mounting ring 102 after installation. The position of the moving block 105 can be adjusted according to the needs of use by adjusting the screw 103, thereby improving applicability.

[0027] like Figure 1-3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the wire supporting component includes a wire supporting ring 110 fixedly connected to the top wall of the moving block 105, the top wall of the wire supporting ring 110 is connected to a limiting ring 111, the limiting ring 111 and the wire supporting ring 110 are connected by a mounting bolt 118, and the limiting ring 111 and the wire supporting ring 110 can be fixed by setting the mounting bolt 118, which is more convenient to use.

[0028] like Figure 1-5As shown, as a preferred embodiment, on the basis of the above method, further, the top wall of the limit ring 111 is threadedly connected with an adjusting bolt 112, the inner wall of the mounting bolt 118 is threadedly connected with a limit screw 113, and two groups of limit screws 113 are symmetrically arranged about the central axis of the mounting bolt 118. One end of the limit screw 113 passes through the mounting bolt 118 and is also threadedly connected to the adjusting bolt 112. The limit screw 113 is convenient for rotating into the adjusting bolt 112, thereby preventing the mounting bolt 118 from loosening and improving the firmness.

[0029] like Figure 1-4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the inner wall of the wire supporting ring 110 is fixedly connected with uniformly distributed first springs 114, and the end of the first spring 114 away from the wire supporting ring 110 is also fixedly connected with a group of first clamping plates 115, and the inner wall of the limiting ring 111 is fixedly connected with uniformly distributed second springs 116, and the end of the second spring 116 away from the limiting ring 111 is also fixedly connected with a group of second clamping plates 117.

[0031] Specifically, when using this new type of power tension wire clamp: first, put the first mounting ring 100 and the second mounting ring 102 on the position where they need to be installed, and then tighten the fixing bolt 101 to achieve the connection between the first mounting ring 100 and the second mounting ring 102, and then rotate the extrusion screw 120 to drive the fixing pad 121 to move, and at the same time manually rotate the fixing pad 121 so that it can better fit with the support column, and by tightening the extrusion screw 120, the stability of the first mounting ring 100 and the second mounting ring 102 after being fixed can be achieved. When the installation is completed, the moving block 105 is driven to slide through the sliding rod 104 by rotating the adjusting screw 103, thereby achieving the adjustment of the distance between the wire supporting ring 110 and the limiting ring 111, so as to better adapt to the wires, and then the wires are clamped between the wire supporting ring 110 and the limiting ring 111, and the wire supporting is achieved through the mounting bolt 118 The connection between the ring 110 and the limiting ring 111, when the mounting bolt 118 is tightened, the limiting screw 113 is turned downward. When the limiting screw 113 moves to the top of the adjusting bolt 112, the adjusting bolt 112 is turned so that the notch on the adjusting bolt 112 is matched with the limiting screw 113, and then the limiting screw 113 is continued to be turned into the adjusting bolt 112, thereby improving the firmness of the wire supporting ring 110 and the limiting ring 111 after installation, and facilitating to prevent falling off. When the wire expands due to heat, the first clamping plate 115 and the second clamping plate 117 expand outward under the action of the first spring 114 and the second spring 116. When the wire contracts, the first spring 114 and the second spring 116 drive the first clamping plate 115 and the second clamping plate 117 to better fit the wire, thereby improving the stability of the wire, preventing the wire from shaking, and increasing the service life of the wire.
