Description
The present invention relates to a kind of being used for inserts equipment in the pipeline to stay cord, more particularly, relates to a kind of air stream drives shuttle that is used to realize above-mentioned insertion.With reference to the shuttle that is used for inserting stay cord communication cable should be used for describing the present invention, but this should not constitute can applicablely limit form of ownership of the present invention.
Nowadays, communication cable is laid in the underground special-purpose trench usually.In order to keep cable to avoid may damaging of water, rubble and insect, generally in plastics (normally polyvinylchloride) pipeline, lay communication cable.The above-mentioned cable laying of existing thousands of kilometers is in underground piping, but because the developing rapidly and need more cable, the following cable that can need the hundreds of thousands kilometer of imagination of telecommunications industry.
Mounted pipeline has three classes usually: prepare to wait for receive the vacant pipeline of new cable, the pipeline that had partly taken already and fill the pipeline of cable fully.The present invention relates generally to the above-mentioned first kind and the second class pipeline.Time-consuming the taking a lot of work of process of cable insertion pipeline, thus expensive.The existing method of stay cord being inserted pipeline is slow, trouble and poor efficiency.
In order to send piping cable, need earlier stay cord to be inserted in the pipeline, then stay cord is fixed to the front end of cable, arrive its end so that can be pulled through a segment pipe to cable.Can insert stay cord in advance, and just be placed in the pipeline, insert cable thereafter to wait for.This helps the cable setter, because in this case, stay cord is put into pipeline before cable is installed, and makes stay cord be connected in the front end of cable easily, by stay cord cable is pulled through pipeline then.A kind of existing method stay cord insertion pipeline comprises uses one stay cord connection original umbrella shape part (parachute) thereon.This umbrella shape part inserts in the pipeline by upstream end.Then compressed air is delivered to the umbrella shape part from the air source, made its inflation, it penetrates pipeline subsequently, and stay cord also penetrates with it.In order to keep required positive air pressure, the upstream end of necessary closed conduit is in case air spills from upstream end.This is realizing that with raw mode wearing or featuring stage armour cloth waste (rags) or similar material insertion pipe head these materials must keep the location with hand to malleation when introducing in the pipeline at present.By a steel pipe that is connected in compressed air source malleation is introduced in the pipeline.Cloth waste and other packaging material are around copper pipe.Stay cord must fully freely pass packaging material or move around it, and the integrality that this will take into account sealing causes the pressure loss of pipe head.Use said method another problem also to occur, that is, undesirable folding or bonding appears in the umbrella shape part.At present the umbrella shape part that uses is made up of one deck textile material or similar material basically, has connected an end of each multistage line etc. at the point of its periphery, and each section line terminates in a joint that also connects the stay cord front end at its other end.
The umbrella shape part is folding in pipeline easily, and the suitable situation of bypass symmetry and flow equilibrium is compared during especially with normal running, if collect air in the umbrella shape part asymmetricly, will make more air walk around an edge from bypass.This imbalance can cause the umbrella shape part to rotate, the entanglement connecting line, and in this case, line can be captured the textile material of the collection air of umbrella shape part.This means that the umbrella shape part of entanglement can blocking pipe, must take out, thereby the process of being introduced can make the insertion of stay cord increase time and workload from pipeline.In practice, before realizing successful insertion, this problem can repeat to take place.
Take ducted cable in part and form because of intersection under the situation of V-arrangement, a problem may also can occur, at this moment cable is at V-arrangement arrow path place interception umbrella shape part.When this happens, stay cord (line) continues to be caused a kind of impression by the capture point of blows air over umbrella shape part to operating personnel: the umbrella shape part is also hauling stay cord by pipeline, and in fact at this moment it has blocked.Must discharge the umbrella shape part from capture point, the practice is: stay cord is passed pipeline toward pulling back, repeat insertion process subsequently, till the umbrella shape part successfully moves past pipeline.This is a poor efficiency, takes a lot of work with time-consuming.
Use prior-art devices, also have some other problems: for example, the stay cord line contact user's hand during sending rope, thereby brings the danger of ' rope burn ', and copper pipe must and be packed cloth waste and foamed material prevents to blow out together by operator's fix in position.In addition, need two people usually in piping shaft, a people carries stay cord, and another is fixed copper air line and cloth waste in position.
In another kind of art methods, can insert some push rods from the two ends of pipeline, till an INTRM intermediate point met, the way point cut off and jointed pipe hereinto until them, from and produce a undesirable joint, this forms the place of the harmful water of another place's infiltration.Push rod can insert from pipeline one end and reach 100 meters.This method is a trouble, and may cause the pipeline inner cable to damage, and especially engages under the situation of above-mentioned v-shaped structure at push rod, and is all the more so.
The invention provides a kind of stay cord that makes and can insert equipment in the pipeline without difficultyly, be suitable for cable laying, communication cable for example, but be not limited to communication cable.Application of the present invention relates to a kind of equipment, and it has become the theme of the common application co-pending of the applicant's proposition, is intended to overcome the problem of above-mentioned art methods.According to the present invention
