Problems solved by technology

[0003] The use of cables plays a vital role in the process of urbanization, and due to the particularity of the conditions of use of cables, they often need to be erected in a very high environment, so for this kind of cable support, often due to high altitude wind This causes vibrations in the cable as well as in the cable support
[0004] In the prior art, when the cables at both ends of the cable support are subjected to wind force, the cables will generate a thrust to the cable support, thereby causing the cable support to vibrate, which is easy to cause damage to the cable support, which has a great potential safety hazard and is not conducive to Long-term development of urban construction

Abstract

The invention discloses an anti-seismic device for power cables, which comprises a U-shaped main bracket, a supporting column, a cable cover and a steel wire rope. Pipe sleeve, the lower pipe sleeve is symmetrically set up with steel wire ropes on both sides of the connecting block, and a hinge rod is arranged between the connecting rod and the upper pipe sleeve. Rotational connection, the lower sleeve is provided with a mounting groove corresponding to the supporting column, and a radial spring is fixed between the supporting column and the side wall of the mounting groove along the radial direction of the cable sleeve, and between the supporting column and the side wall of the mounting groove An axial spring is fixed along the axial direction of the cable sleeve. The present invention simultaneously supports the cable sheath via the rigid and flexible support members, so that the overall device has a better supporting effect on the cable sheath, and makes the anti-seismic effect better and more effective.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an anti-seismic device for power cables. Background technique [0002] With the rapid development of science and technology, various new technologies and new inventions emerge one after another, and are quickly applied to industrial production, which greatly promotes economic development. With the continuous development of my country's economic construction and the acceleration of urbanization, building materials received great attention. [0003] The use of cables plays a vital role in the process of urbanization, and due to the particularity of the conditions of use of cables, they often need to be erected in a very high environment, so for this kind of cable support, often due to high altitude wind This causes vibrations in the cables and cable supports. [0004] In the prior art, when the cables at both ends of the cable support are subjected to wind force, the cables w...
