Description

A kind of elastic suspending cable clamp

Technical field

The utility model relates to hoist cable apparatus field more particularly to a kind of elastic suspending cable clamps.

Background technique

Contact net is to take the high pressure of stream defeated for pantograph with what " it " font was set up along rail overhead in electric railway Electric wire is the special shape powered to electric locomotive that downline overhead is set up as the main truss of railway electrification project Transmission line of electricity, by contact suspension, device, positioning device, pillar and basic several parts is supported to form.Wherein high-speed electrified The most commonly used is elastic chain type hangings in railway contact line, i.e., a set of elastic suspending device are being added at pillar hitch point, make With being the elasticity for increasing contact line fixed point at pillar, reduces the hard spot of anchor point, be conducive to motorcycle pantograph and take stream；Elastic lifting Bands folder is exactly the important part for being fixedly connected with elastic suspending and carrier cable, usually by being bolted muti-piece clamping plate to co-clip Tight carrier cable and elastic suspending.In an electric railway, it usually needs a large amount of elastic suspending cable clamp is used, and it is existing When in use, need to remove bolt from clamping plate makes the separation of each piece of clamping plate to elastic suspending cable clamp, then by carrier cable and elastic lifting Rope is placed between clamping plate, and being screwed into bolt again makes each piece of clamping plate reformulate wire clamp entirety；This structure is in actual use Not only make the installation process of elastic suspending cable clamp relatively complicated, but also each elastic suspending cable clamp requires first to split during installation It will lead to the part of erecting bed when needing to install great number of elastic suspending cable clamp in a railway at several individual parts Quantity is excessive, easily causes the loss of part and the confusion of field management；In addition, in existing elastic suspending between each piece of clamping plate It is matched for clamping tightly carrier cable and elastic suspending by linear rope groove, makes between clamping plate and hoist cable that friction is small, leads to bullet Property suspending cable clamp safety and reliability it is insufficient.

Utility model content

The purpose of the utility model is to provide a kind of elastic suspending cable clamps, and structure is simple, and connection is reliable, without removing bolt I.e. mountable hoist cable.

Used technical solution is the utility model to solve above-mentioned technical problem: a kind of elastic suspending cable clamp, including Middle clamp plate, the upper clamp plate for being matched for clamping tightly carrier cable with middle clamp plate and for being matched for clamping tightly elastic suspending with middle clamp plate It is corresponding on lower clamp plate, upper clamp plate and middle clamp plate to offer for wearing the through-hole for connecting bolt, it is also provided with and is used on upper clamp plate The retaining threaded hole of necking down bolt is worn, retaining threaded hole is located at the side of carrier cable and elastic suspending far from the through-hole, institute It states connection bolt and twists and be located in lower clamp plate, for adjusting the distance between upper clamp plate and lower clamp plate, the necking down bolt is also twisted and set In lower clamp plate, the diameter of the smooth bar part of necking down bolt is less than the outer diameter of threaded portion, in order to which necking down bolt is from lower clamp plate In back-out, to make to form the gap that passes through for carrier cable and elastic suspending between necking down bolt and lower clamp plate, pass through retaining spiral shell Pit is back-outed from upper clamp plate to avoid necking down bolt.

Preferably, offer on the upper clamp plate has long along carrier cable with the matched rope groove of carrier cable, rope groove middle part The first arcuate recess section of direction setting is spent, the side of middle clamp plate also offers rope groove, has one section of folder upwards in the middle part of the rope groove The the first arcuation raised section to be formed is protruded in plate direction, and the first arcuation raised section and the location and shape of the first arcuate recess section are right It should be arranged.

Preferably, offering on the lower clamp plate has with the matched rope groove of elastic suspending, rope groove middle part along elastic lifting Second arcuate recess section of rope length direction setting, the side of middle clamp plate also offers rope groove, have in the middle part of the rope groove one section to Protrude the second arcuation raised section to be formed, the location and shape of the second arcuation raised section and the second arcuate recess section in lower clamp plate direction It is correspondingly arranged.

Preferably, the positioning plate and one piece of adjustable plate for offering through-hole that the middle clamp plate offers rope groove by one piece connect It constitutes.

Preferably, the connection bolt and necking down bolt are arranged in parallel, in order to cooperate adjust upper clamp plate and lower clamp plate it Between distance.

Preferably, the quantity of the connection bolt and necking down bolt is two, and four bolts are in distributed rectangular.

Preferably, lower clamp plate is run through in the connection bolt and the stubborn one end being located in lower clamp plate of necking down bolt, and connects The length of bolt-through lower clamp plate is greater than the length of necking down bolt-through lower clamp plate.

Preferably, institute's upper clamp plate is equipped with the counterbore being connected to retaining threaded hole, presss from both sides upwards in order to increase necking down bolt The distance of plate movement.

According to the above technical scheme, the beneficial effects of the utility model are:

A kind of elastic suspending cable clamp provided by the utility model, when in use back-outs necking down bolt from lower clamp plate, because Diameter for the smooth bar part of necking down bolt makes less than the outer diameter of threaded portion so necking down bolt can be moved to upper clamp plate Gap is generated between necking down bolt and lower clamp plate, carrier cable and elastic suspending can be passed through from gap and is placed into middle clamp plate It is clamped between upper lower clamp plate, so in use just without all removing three pieces of clamping plates from connection bolt, and can Carrier cable and elastic suspending are penetrated still to pass through in the case that connection bolt forms elastic suspending cable clamp entirety in three pieces of clamping plates, Compared with existing elastic suspending cable clamp, not only installation process is greatly simplified, but also can be avoided the number of parts of erecting bed Excessively, the loss of part and the confusion of field management would not also be caused.

Also, because what upper clamp plate opened up is retaining threaded hole, necking down bolt can not be back-outed from upper clamp plate, when for Installation hoist cable and when necking down bolt is back-outed from lower clamp plate, even if in necking down bolt head situation directed downwardly, necking down spiral shell Bolt will not be fallen from retaining threaded hole, not only be avoided that necking down bolt falls the safety for hurting sb.'s feelings to guarantee installation process Property, also it is avoided that necking down bolt is lost because of separating with elastic suspending cable clamp main body.

It is and existing by being correspondingly arranged recess section and the raised section of arcuation in the rope groove of clamping plate in the utility model Elastic suspending is compared using linear rope groove, increases the contact area between clamping plate and hoist cable, to increase carrier cable With the deflection of elastic suspending, also increase the frictional force between clamping plate and hoist cable, make elastic suspending cable clamp safety and can It gets a promotion by property.
