Detailed Description

For the purpose of enhancing the understanding of the present invention, the following detailed description of the present invention will be made with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.

As shown in fig. 1 to 5, a straight pull type strain reinforcement device comprises a wedge-shaped strain clamp (adopting an all-aluminum alloy structure and having no electromagnetic loss) and a combined turnbuckle, wherein the wedge-shaped strain clamp comprises an upper drawer 1, a lower drawer 2, an upper wedge 3, a lower wedge 4, a clamp hanging plate 5 and a shell 6, and the upper drawer 1, the clamp hanging plate 5 and the shell 6 are an integral component. The upper drawing box 1 and the lower drawing box 2 are respectively positioned at the top and the bottom of the shell 6, the upper wedge 3 and the lower wedge 4 clamp a wire 14 (the side surface of the wedge is vertical to the horizontal plane) and are inserted between the upper drawing box 1 and the lower drawing box 2, the shell 6 is movably connected with one end of the wire clamp hanging plate 5, the other end of the wire clamp hanging plate 5 is fixed with a combined turn buckle, the combined turn buckle comprises a U-shaped bolt 7, a locking nut 8, a body sleeve 9 and a bolt hanging plate 10, the body sleeve 9 is sleeved on the U-shaped bolt 7 and the bolt hanging plate 10 and is fixed through the locking nut 8, and the bolt hanging plate 10 is fixed with the wire clamp hanging plate 5 through a fixing bolt 11. The part of the lead 14 between the U-shaped bolts 7 is provided with a compression type strain clamp 12, and the compression type strain clamp 12 is connected with the bottom of the U-shaped bolt 7 through an anchor ring 13. The tension of the wedge-shaped strain clamp is controlled by adjusting the fixing bolt so as to share the tension of a lead born by the original compression type strain clamp, and the phenomenon that the clamp is damaged to cause string drop is avoided.

The installation method comprises the following steps: the method comprises the following steps of (1) disassembling a wedge-shaped wire clamp; (2) Cleaning the wires at the installation part to remove dirt and an oxide layer; (3) The upper drawer 1, the wire clamp hanging plate 5 and the shell 6 are an integral component, put in the proper position of the wire and inserted into the lower drawer 2; (4) The upper wedge 3 and the lower wedge 4 are used for clamping the wire from top to bottom, and the side faces of the two wedges are ensured to be vertical to the horizontal plane. And then the whole assembly is tightly pushed in, so that the installation of the wedge-shaped strain clamp can be completed. (5) And (3) the combined turnbuckle is disassembled, the U-shaped bolt part penetrates into an anchor ring 13 of the steel anchor, the body sleeve 9 and the bolt hanging plate 10 are assembled, and the bolt hanging plate 10 is connected with the wire clamp hanging plate 5 of the wedge-shaped strain clamp. (6) The wedge-shaped strain clamp is pre-tightened by adjusting the fixing bolt 11 of the upper bolt hanging plate 10 of the turnbuckle, and the assembly is completed.

The device has wide application range, convenient operation, time saving and labor saving; traditional reinforcement fastener needs the DB adjusting plate to be used for the installation, but not all strain insulator strings all are equipped with the DB adjusting plate, need tighten up the wire during use and tear the cluster and reorganize, waste time and energy and also can cause the influence to the original force balance of circuit. The device does not need to tighten up a lead, and can be installed by directly utilizing the steel anchor ring, so that the operation is convenient and reliable, and the time and the labor are saved. The adjustable tension clamp is suitable for compression type strain clamps of different models by adjusting the opening size and is suitable for installation of various split conductors.
