Description

800KV tension insulator wire end fixture

technical field

The utility model relates to a part of a fixture for replacing strain insulators of UHV transmission lines, in particular to a fixture for wire ends in the fixture for replacing 800KV strain insulators.

Background technique

The existing clamps used to replace the entire string of insulators in the tension string of UHV transmission lines are mainly composed of wire end clamps, traction plate clamps and manual screw. It consists of a wire end clamp, a closed clamp and a manual screw. The wire end clamp in the two clamps is an integral flip clamp, which is mainly composed of a main body 12 and a flip 13 Composition, the main part is an integral component, as shown in Figure 9. The disadvantages of this wire end fixture are: the processing of the main card is difficult and the cost is high; the weight is heavy, it is inconvenient to carry, and it is not conducive to high-altitude operations.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned shortcomings of the existing wire end clamps, and propose a combined wire end clamp.

The technical solution to achieve the above purpose is: a fixture for the end of the 800KV strain insulator wire, including a main body and a flap. Both ends of the main body and one end of the flap have mounting holes for tie rod joints. The main body and the flap There are cavity holes corresponding to the position on the part, and it is characterized in that the main part is an assembly part, which is composed of a main board and a sub-board fastened and connected by at least two sets of double-headed step bolts, the main board and the sub-board are spaced and parallel, and the main body The cavity hole on the part is on the main board; the flap part is hinged to the corresponding side of the sub-board, and the panel surface formed after the hinge is the same as the main board; the cavity formed by the flip part and the main part is double Match the shape of the bowl head.

Further, the cavity hole is an oblate hole.

Further, both the main body part and the flap part are made of titanium alloy.

The utility model is easy to process, convenient to assemble, light in weight, convenient to carry, and beneficial to high-altitude operations.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

The utility model relates to a fixture at the end of an 800KV strain insulator lead, which includes a main body and a flap.

As shown in Figure 4, the main body is an assembly, including a main board 1 and a sub-board 2;

As shown in Figure 1, the main board 1 is a flat plate similar to an obtuse-angled isosceles triangle. There is a cavity hole 6 in the middle that matches the double-connected bowl head of the fittings, and there is a tie rod at the two ends near the bottom. The joint installation hole 5 is also provided with two stepped bolt holes 4 at intervals on one side of the main board 1;

As shown in Figure 2, the sub-board 2 is also a flat plate, about 1/3 of the length of the main board 1, and its shape is the same as that of the side with two stepped bolt holes 4 on the main board 1, also with two stepped bolt holes 4 , the end of which has a rod joint mounting hole 5;

As shown in Figure 4, the main body 1 and the auxiliary board 2 are fastened and connected by two sets of double-headed step bolts 7 to form the main body, and the main board 1 and the auxiliary board 2 are spaced apart and parallel;

As shown in Figure 3, the flap member 3 is also a flat plate, with a cavity hole 6 adapted to the double-connected bowl head of the fittings on the layout, and a tie rod joint installation hole 5 at one end;

As shown in Fig. 5, the corresponding side of the turnover member 3 and the sub-board 2 is hinged by a pin 8, and the panel surface formed after the hinge is the same as the main board 1;

As shown in FIG. 6 and FIG. 7 , the mold cavity 10 formed after the flap member 3 is fastened with the main body is adapted to the shape of the double bowl head of the line fitting.

During use, the flap part 3 is fastened with the main body, so that the mold cavity 10 is set on the double-connected bowl head of the line fittings, and the tie rod joint 11 is installed on the tie rod joint mounting hole 5 with the tie rod joint bolts 9 at both ends.

In this embodiment, the cavity hole 6 is an oblate hole. The oblate hole can increase the contact surface between the double-connected bowl head of the line fittings and the cavity, and can improve the extrusion strength and safety of the utility model.

In this embodiment, both the main body part and the flap part 3 are made of titanium alloy.
