Description

Technical Field

[0001] The utility model relates to the technical field of spacer dampers, in particular to an eight - split anti - galloping spacer damper. Background Art

[0002] In overhead transmission lines, spacer dampers have the functions of preventing whip - lashing between split sub - conductors, suppressing aeolian vibration and sub - span oscillation, etc. The spacer damper mainly includes a frame body and connection clamps connected to the frame. The clamp head of the connection clamp is used to tightly hold the split sub - conductors, and through the limit structure at the connection between the frame body and the connection clamp, the clamp can rotate a certain angle along the tangent direction under the action of the axial torsional force of the conductor.

[0003] At present, for the eight - split conductor bundle, single - piece spacer dampers are used to fix the relative positions of the eight conductors to play a spacing role. However, since the eight - split conductor bundle is mostly installed outdoors, under the action of the external environment, the eight - split conductor bundle will shake, causing the single - piece spacer damper to shift, resulting in contact and entanglement inside the eight - split conductor bundle, and further causing damage to the eight - split conductor bundle. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an eight - split anti - galloping spacer damper.

[0005] To achieve the above - mentioned purpose, the utility model adopts the following technical solutions:

[0006] An eight - split anti - galloping spacer damper includes: two distance - limiting rods. At both ends of the two distance - limiting rods, eight - split base structures are respectively installed. On the eight straight sides of the eight - split base structure, main support structures are respectively installed. On the side wall surfaces of the eight main support structures, auxiliary support structures are respectively installed. The two eight - split base structures include: a support circular seat, eight support connecting rods and a support outer frame. The support circular seat is installed at one end of the two distance - limiting rods. The eight support connecting rods are respectively installed outside the support circular seat, and the eight support connecting rods are equally spaced. The support outer frame is installed outside the eight support connecting rods.

[0007] The utility model is further set that the support outer frame is a regular octagon, and two mounting holes are respectively opened on the side wall surface of each side of the support outer frame.

[0008] The utility model is further set that the main support structure includes: a main support seat, a main support rod and a main support outer tube. The main support seat is installed outside the support outer frame by bolts. One end of the main support rod is installed on the outer wall surface of the main support seat, and the main support outer tube is installed at the other end of the main support rod.

[0009] The present utility model is further configured such that the auxiliary support structure includes: an auxiliary rotating seat, a return spring, and an auxiliary support outer tube; the auxiliary rotating seat is installed on the side wall surface of the main support rod, the auxiliary support outer tube is installed at the end of the auxiliary rotating seat, and the return spring is installed inside the auxiliary rotating seat.

[0010] The present utility model is further configured such that a friction-resistant pad is installed on the inner wall surface of the main support outer tube.

[0011] The present utility model is further configured such that a friction-resistant pad is installed on the inner wall surface of the auxiliary support outer tube.

[0012] The beneficial effects of the present utility model are as follows: Under the action of the main support structure and the two auxiliary support structures, the present utility model realizes the positioning support of three points for a single wire, which can ensure that the internal twisting and winding of the eight-split wire group occur, ensuring the safety of the eight-split wire group. At the same time, the two distance limiting rods can limit the distance between the two eight-split base structures, and can also limit the parallel positional relationship between the two eight-split base structures, as well as the vertical positional relationship between the eight-split base structure and the eight-split wire group, so that the present utility model can stably support the eight-split wire group.

For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0021] Referring to Figures 1-3 , an eight-split anti-galloping spacer damper, comprising: two distance-limiting rods 1. At both ends of the two distance-limiting rods 1, eight-split base structures are respectively installed. Main support structures are respectively installed on the eight straight edges of the eight-split base structures. Auxiliary support structures are respectively installed on the side wall surfaces of the eight main support structures; the two eight-split base structures include: a support circular seat 2, eight support connecting rods 3, and a support outer frame 4; the support circular seat 2 is installed at one end of the two distance-limiting rods 1. The eight support connecting rods 3 are respectively installed outside the support circular seat 2, and the eight support connecting rods 3 are equally spaced. The support outer frame 4 is installed outside the eight support connecting rods 3. The support outer frame 4 is a regular octagon, and two mounting holes are respectively formed on the side wall surface of each side of the support outer frame 4. The two distance-limiting rods 1 can limit the distance between the two eight-split base structures and can also limit the parallel positional relationship between the two eight-split base structures, so that the utility model can stably support the eight-split wire group.

[0022] Specifically, the main support structure includes: a main support base 5, a main support rod 6, and a main support outer tube 7; the main support base 5 is installed outside the support outer frame 4 by bolts, one end of the main support rod 6 is installed on the outer wall surface of the main support base 5, and the main support outer tube 7 is installed at the other end of the main support rod 6. The auxiliary support structure includes: an auxiliary rotating seat 8, a return spring 9, and an auxiliary support outer tube 10; the auxiliary rotating seat 8 is installed on the side wall surface of the main support rod 6, the auxiliary support outer tube 10 is installed at the end of the auxiliary rotating seat 8, and the return spring 9 is installed inside the auxiliary rotating seat 8. A friction-resistant pad 11 is installed on the inner wall surface of the main support outer tube 7, and a friction-resistant pad 11 is installed on the inner wall surface of the auxiliary support outer tube 10. Under the action of the main support structure and the two auxiliary support structures, three-point positioning support for a line is achieved, which can ensure that the eight-split wire group twists and winds internally, ensuring the safety of the eight-split wire group.

[0023] Working principle: First, the present utility model needs to be installed. The present utility model can be installed outside the eight-split wire group. The operator directly clamps two auxiliary support outer tubes 10 and one main support outer tube 7 on one wire in the eight-split wire group until the entire eight-split wire group is installed. Since two auxiliary support outer tubes 10 and one main support outer tube 7 fix one wire, it has good stability and can keep the support circular seat 2 and the eight-split wire group in a perpendicular position relationship. At the same time, when the eight-split wire group shakes, the auxiliary rotating seat 8 will bend, and under the action of the return spring 9, the auxiliary rotating seat 8 will rebound to reset. At the same time, support circular seats 2 are respectively arranged at both ends of the two distance limiting rods 1, which can not only ensure the perpendicular position relationship between the support circular seat 2 and the eight-split wire group, but also prevent the eight-split wire group from twisting and winding together, ensuring the safety of the eight-split wire group.

[0024] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
