Description

Cable vibration-proof device for railway communication

Technical Field

The utility model relates to a vibration-proof device especially relates to a cable vibration-proof device for railway communication.

Background

A small hammer, called as a damper, is usually hung on a wire close to two sides of a cable for railway communication on an overhead line and is arranged for reducing the vibration of the wire caused by wind power, the overhead line of the communication cable is higher in pole position and larger in span, when the wire is under the action of wind force, vibration occurs, and when the wire vibrates, the working condition at the suspension part of the wire is the most unfavorable, because of multiple vibration, the lead can generate fatigue damage due to periodic bending, when the span of the overhead line is more than 120 meters, the damper is generally used for vibration isolation, and the conventional damper can only reduce the amplitude of the cable, but in reality, the vibration of the cable caused by wind force is generally small in amplitude, the vibration frequency is high, vibration is accompanied by torsional force, the damage of the vibration frequency and the torsional force to the cable at the hanging part is very large, and the existing vibration-proof device can not solve the problems.

Disclosure of Invention

According to the technical problem, the utility model provides a cable anti-vibration device for railway communication, its characterized in that includes damper pipe, anti-twist spring, connecting piece, installation pole, damper, damping spring, fixed part, mounting hole, damper pipe includes inlayer, skin, arch again, skin and the concentric suit of inlayer are in the inlayer outside, be equipped with a plurality of archs on the outer inner wall, damper pipe right side is equipped with anti-twist spring, the fixed connecting piece that is equipped with in damper pipe bottom, the connecting piece bottom is equipped with the installation pole, installation pole both ends are equipped with the damper, damper pipe left side is equipped with damping spring, damping spring one end and damper pipe's outer fixed connection, the damping spring other end is equipped with the fixed part, be equipped with the mounting hole on the fixed part.

Further, the mounting rod is arranged in parallel with the anti-vibration pipe.

Furthermore, the anti-torsion spring is fixedly connected with the inner layer of the anti-vibration tube.

Further, the inner layer outer wall is in contact with the top of the protrusion.

Further, the vibration reduction spring is arranged obliquely to the vibration prevention pipe, and the inclination angle ranges from 30 degrees to 60 degrees.

The utility model has the advantages that: the utility model relates to a cable antivibration device for railway communication is with the fixed parcel of inlayer on the cable during use, with outer suit in the inlayer outside, prevents turning round spring horizontal direction and cable support fixed connection, damping spring slope and cable support fixed connection, both can reduce the torsional force through preventing turning round the spring by a large extent, can reduce the frequency of vibration through damping spring's slowly-releasing again, has avoided the damage to the cable of department of hanging.

fig. 2 is a sectional view of the vibration preventing pipe;

fig. 3 is a schematic view of the usage state of the present invention.

As shown in the figure, the anti-vibration pipe-1, the inner layer-11, the outer layer-12, the bulge-13, the anti-torsion spring-2, the connecting piece-3, the mounting rod-4, the anti-vibration hammer-5, the damping spring-6, the fixing part-7, the mounting hole-8, the cable-9 and the cable bracket-10.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings: the utility model relates to a cable vibration-proof device for railway communication, which is characterized by comprising a vibration-proof pipe 1, an anti-torsion spring 2, a connecting piece 3, an installation rod 4, a vibration-proof hammer 5, a vibration-proof spring 6, a fixing part 7 and an installation hole 8, wherein the vibration-proof pipe 1 comprises an inner layer 11, an outer layer 12 and a bulge 13, the outer layer 12 and the inner layer 11 are concentrically sleeved outside the inner layer 11, a plurality of bulges 13 are arranged on the inner wall of the outer layer 12, the right side of the vibration-proof pipe 1 is provided with the anti-torsion spring 2, the anti-torsion spring 2 is fixedly connected with the inner layer 11 of the vibration-proof pipe 1, the outer wall of the inner layer 11 is contacted with the top of the bulge 1, the bottom of the vibration-proof pipe 1 is fixedly provided with the connecting piece 3, the bottom of the connecting piece 3 is provided with the installation rod 4, the installation rod 4 is arranged in parallel with the vibration-proof pipe 1, two, the vibration damping device is characterized in that the vibration damping spring 6 is arranged obliquely to the vibration damping pipe 1, the inclination angle ranges from 30 degrees to 60 degrees, one end of the vibration damping spring 6 is fixedly connected with the outer layer of the vibration damping pipe 1, the other end of the vibration damping spring 6 is provided with a fixing part 7, and the fixing part 7 is provided with a mounting hole 8.

The working principle is as follows: before carrying out the built on stilts operation to cable 9, with the fixed parcel of inlayer 11 on cable 9, with outer 12 suit in the inlayer 11 outside, will prevent 2 horizontal directions of torsion spring and cable 9 support fixed connection when built on stilts, damping spring 6 slope and cable support 10 fixed connection, when the vibration that wind-force arouses appears, thereby the amplitude of cable is reduced to the outer wall of inlayer 11 and the protruding 13 looks mutual friction of skin 12, the torsional force that reduces cable 9 that prevents torsion spring 2 very big degree and accompany at the in-process of vibration, damping spring 6 one end is connected with cable support 10 through passing the mounting hole 8 with the bolt simultaneously, one end and the outer 12 fixed connection of anti-vibration pipe 1, can effectively reduce the frequency of vibration, the damage to the cable 9 of department of hanging has been avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
