Description

Anti-slip damper

Technical Field

The utility model relates to a transmission equipment technical field especially relates to an antiskid damper that shakes.

Background

The damper is used for reducing the vibration of the wire caused by wind force. The high-voltage overhead line has high pole position and large span, and can vibrate when the wire is acted by wind. The working conditions at the wire suspension are most unfavourable when the wire vibrates. Due to multiple vibrations, fatigue failure of the wire may occur due to periodic bending. When the span of the overhead line is more than 120 meters, a damper is generally adopted to prevent vibration.

The existing connection mode of the anti-vibration hammer and a wire is usually directly fixed by a bolt and a nut, and the mode has the defects that the bolt and the nut are independent parts, a long bolt is firstly inserted into a through hole in an anti-vibration hammer clamp when workers work aloft, then a gasket and the nut are sleeved on the bolt, finally the nut is screwed by a spanner, and the bolt is fixed by the spanner to keep the bolt still when the nut is screwed, so that the anti-vibration hammer can be fixed, the whole process is very complicated, and the bolt and the nut can fall off from the high altitude if the bolt and the nut are not properly operated a little, so that the structure is simple, but the operation is very inconvenient; the other structure is that the bolt or the nut is fixed in the damper wire clamp, a hexagonal hole is usually formed in the wire clamp, the bolt or the nut is put in, the nut or the bolt only needs to be screwed to be fixed, the structure is slightly complex, the installation is convenient and fast, the service time of the structure is short, the damper is under the action of weather conditions such as wind, ice and low temperature, the structure is exposed in the field environment for a long time, rainwater can stay in the hexagonal hole, the bolt or the nut is corroded, the damper can slide and run away, the fixing of the damper to the cable cannot achieve the original effect, strand breakage and wire breakage of the cable can be caused, one operator must maintain one of the cable, the mode is too troublesome, the working strength of the operator is increased, and inconvenience is brought to the work of the operator.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide an anti-slip damper.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides an antiskid damper, includes tup and fastener, the fastener pass through the steel strand wires with its characterized in that is connected to the tup: the fastener includes left clamp splice and right clamp splice, the upper portion of left clamp splice and right clamp splice corresponds respectively and is equipped with the arc clamping groove, the arc clamping inslot is equipped with rubber, the lower part of left side clamp splice is equipped with the couple, the inboard of right side clamp splice be equipped with couple complex slot, the dorsal part of right side clamp splice is equipped with by the hexagonal recess, be equipped with the bolt hole of coaxial line on the bottom of hexagonal recess and the left clamp splice respectively, the hexagonal recess internal-fastening cooperation has hexagon nut, the bolt that has the nut from the bolt hole of left clamp splice get into and with the hexagon nut threaded connection in the hexagonal recess, be equipped with on the lower lateral wall of hexagonal recess and extend to the outside water conservancy diversion hole of right clamp splice, and water conservancy diversion hole site in hexagon nut's top.

Preferably, the top of the right clamping block is higher than the top of the left clamping block.

Preferably, a spring gasket is arranged between the nut and the left clamping block.

The beneficial effects of the utility model are that the utility model discloses improve current fastener, firstly, rubber has been increased, increase the frictional force between fastener and the cable, prevent that the fastener is not hard up, secondly set up a water conservancy diversion hole in six groove recesses, timely get rid of the rainwater, it leads to the nut not hard up to prevent corroding threaded connection department, three be with the fastener fall into about two parts, the mode connection through the couple is passed through to the bottom, before the use, bolt and nut link together, a left side, the open space in upper portion of right clamp splice is enough to make the cable get into, so the workman is when high altitude construction, only need to screw up the nut with the spanner and just can fix the fastener, need not other instrument, it is very convenient to assemble.

Detailed Description

As shown in fig. 1-3, an anti-slip damper comprises a hammer head 1 and a wire clamp 2, wherein the wire clamp is connected with the hammer head through a steel strand 3, the wire clamp comprises a left clamping block 4 and a right clamping block 5, as shown in fig. 3, the left clamping block and the right clamping block are special in shape and are directly cast and molded in a mold, the upper parts of the left clamping block and the right clamping block are respectively and correspondingly provided with an arc-shaped clamping groove 6, the arc-shaped clamping grooves are matched with the outer diameter of a cable and are used for clamping the cable, in order to clamp the cable more tightly, rubber 7 is arranged in the arc-shaped clamping grooves, the rubber can adopt two modes, one mode is that the rubber with lines on the surface is directly adhered to the inner side of the arc-shaped clamping grooves in an adhesion mode, and the other mode is a split structure, when the damper is used, the rubber is firstly wrapped on the cable and then is clamped and fixed. In order to adjust the opening angle of the upper parts of the left clamping block and the right clamping block, a hook 8 is arranged at the lower part of the left clamping block, a groove 9 matched with the hook is arranged at the inner side of the right clamping block, and the hook is hung in the groove, namely the left clamping block and the right clamping block are hinged together. In order to fix hexagon nut in advance, the dorsal part of right clamp splice is equipped with by hexagon groove 10, be equipped with the bolt hole 11 of coaxial line on hexagon groove's bottom and the left clamp splice respectively, fastening fit has hexagon nut 12 in the hexagon groove, hexagon nut is impressed in the hexagon groove through interference fit's mode, bolt 14 that has nut 13 gets into and with hexagon nut threaded connection in the hexagon groove from the bolt hole of left clamp splice, the anticlockwise rotation nut, the upper portion of left clamp splice and right clamp splice just outwards opens, supply the cable to put into, after putting into, clockwise rotation nut again, the upper portion of left clamp splice and right clamp splice just presss from both sides tight cable, the lower part of left clamp splice and right clamp splice is through couple and the slot tightly fixed together.

In order to discharge rainwater in the hexagonal groove in time and prevent corrosion of the threaded connection position, a diversion hole 15 extending to the outside of the right clamping block is formed in the lower side wall of the hexagonal groove and located above the hexagonal nut, namely, the diversion hole needs to be leaked out, the hexagonal nut cannot be sealed, the diversion hole is provided with quantity according to the construction condition, if the diameter of the hexagonal groove is large, a plurality of diversion holes need to be drilled, and the quantity is generally enough for two.

The top of right clamp splice is higher than the top of left clamp splice, and there is partial coincidence in the upper portion of the two, is a staggered structure, and the benefit of this kind of structure is the upper portion of right clamp splice parcel with left clamp splice, can effectually prevent like this that the rainwater from getting into between the two.

In order to prevent the bolt from loosening, a spring washer 16 is arranged between the nut and the left clamping block.

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 and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
