Description

Draw ring
Technical field
The present invention relates to a kind of draw ring.
Background technology
Carrier cable system, no matter be all play important effect in power industry or contact line circuit, contact wire or power circuit hang up mainly through dropper by carrier cable.Carrier cable also can carry certain electric current to reduce impedance of traction electric network, reduces voltage loss and energy consumption.
Mounting means conventional is in the market: suspension clamp holds up and clamps cable, suspension clamp is connected with the device such as anchorage, hook by this jockey of U-shaped link plate, because parts are more, installation steps between carrier cable and all parts are comparatively loaded down with trivial details, bring a lot of trouble to high-rise working.And U-shaped link plate adopts malleable cast iron manufacture usually, can produce magnetic hysteresis loss and eddy current loss, the multiple described U-shaped link plate in carrier cable system can produce larger energy loss.If aluminium alloy manufactures jockey, although do not produce magnetic hysteresis loss and eddy current loss, its manufacturing cost is higher, and a large amount of U-shaped link plate of aluminium alloy manufacture that uses can cause carrier cable entire system cost high.
The connection that this jockey of U-shaped link plate carries out between suspension clamp and the device such as anchorage, hook is utilized in prior art, U-shaped link plate has installs inconvenience, negative effect is had to delivery of electrical energy, the defect that price is higher, utilizes draw ring of the present invention to substitute this jockey of U-shaped link plate and can solve these defects well.
Described draw ring is a kind of jockey, two main bodys of described draw ring are equipped with breach, two main bodys utilize respective breach to pierce into the connecting portion of described anchorage circular ring type respectively, then the first main body and the second main body are combined the connection namely completing draw ring and anchorage, described first projection can just block the breach of the second main body, described second projection can block the breach of the first main body, the top of draw ring is made to form a closed annulus, the connection of the first main body and the second main body can be connected by screw, and also can clamping easily connect.And to be placed in described space by the connecting hole position of suspension clamp and after aliging with pin shaft hole, then insert the connection that a bearing pin just can complete suspension clamp and described draw ring very easily.
Workmen aloft operation time, inconvenience very when utilizing U-shaped link plate simultaneously to connect suspension clamp and anchorage, workmen needs to spend much strength suspension clamp, U-shaped link plate and anchorage to be close together and then three is connected and fixed with fixed part, multiple operating personnel may be needed to construct, very inconvenient.And draw ring of the present invention not only mounting means is convenient (only needs merging first main body and the second main body, insert bearing pin and just can complete installation), can also by the connection of draw ring and anchorage, draw ring separates with this two-part operation of connection of suspension clamp, a workmen just can complete installation efficiently, effectively saves construction cost.
Preferably, described first main body and described second main body are equipped with the clamping button for fixing described first main body and described second main body and blocked hole.The merging of the first main body and the second main body can be facilitated by clamping button and blocked hole.
Preferably, the shape of described first main body and the mating shapes of described second main body.Namely be can under the prerequisite of corresponding docking at the projection meeting the first main body and the second main body and breach, the shape of the first main body is identical with the shape of the second main body, facilitate the merging of the first main body and the second main body, and identical the first main body of shape and the second main body only can need a mould during fabrication, conveniently produce and reduce costs.
Preferably, the inner surface of described first main body is provided with some first projections and first groove identical with described first number of slugs, the inner surface of described second main body is provided with some second projections and second groove identical with described second number of slugs, described first projection and described second groove complementation, described second projection and described first groove complementation.
To be connected with the complementation of described groove by described projection that the first main body can be made to be connected with the second main body is more firm, projection and groove are set and can increase contact area between two bodies, be convenient to the conduction of strength, the power simultaneously can effectively disperseing draw ring to be subject to, enables draw ring bear more power.
Preferably, the inner surface of described first main body and described second main body is equipped with cascaded surface, the cascaded surface of described first main body and the cascaded surface complementation of described second main body.
The contact area between two bodies can be increased by the cascaded surface of complementation, effectively disperse the power that draw ring is subject to, enable draw ring bear more power.
Preferably, described cascaded surface is the cascaded surface of second order.Cascaded surface is that the cascaded surface on two rank can play the stressed effect of good dispersion.
Preferably, the inwall that the inwall of described pin shaft hole is provided with zigzag strips or described pin shaft hole is provided with the screw thread for fitted bolt.
The pin shaft hole of draw ring is provided with zigzag strips, after pin shaft hole is corresponding with the connecting hole of suspension clamp, the bearing pin of coupling zigzag strips is inserted in pin shaft hole, just the connection between draw ring and suspension clamp can be completed, described bearing pin can be knocked in described pin shaft hole with hand hammer, and described zigzag strips can make bearing pin more firm in described pin shaft hole.And the pin shaft hole of draw ring is provided with the screw thread for fitted bolt, utilize bolt to do bearing pin, not only easy for installation but also bolt is more firm in described pin shaft hole.
Preferably, the thickness on the top of described draw ring is less than the thickness of described draw ring bottom.The bottom of described draw ring needs to leave space and places described suspension clamp, the bottom of described draw ring needs larger thickness, the top of described draw ring does not then need larger thickness, and the thickness that the thickness on described draw ring top is less than described draw ring bottom can save the manufacturing cost of draw ring.
Preferably, described draw ring adopts nylon to make.The draw ring adopting nylon to make has the advantages such as UV radiation, antiacid caustic corrosion, good mechanical property, tensile wear-resistant, the most important thing is that the draw ring adopting nylon to make is non-conductive, magnetic hysteresis loss and eddy current loss can not be produced, and then can not have a negative impact to delivery of electrical energy.
Preferably, the described first center that is protruding and described second projection is equipped with at least one depression.Described depression can save the materials of draw ring, reduces the manufacturing cost of described draw ring.
Positive progressive effect of the present invention is: draw ring of the present invention is convenient to install, and can not have a negative impact to delivery of electrical energy, firm in structure and with low cost.
