In aforementioned guide device, the support rod is telescopic rod, is used with adapting to various sizes of inspection shaft；
In aforementioned guide device, shown support rod is made of first support bar and second support bar, and the one of first support bar
End offers guide groove along its length, and one end of the second support bar extends in guide groove along its length, and guide groove
Opposite sides be distributed along its length equipped with connecting hole, in the second support bar also along its length be distributed be equipped with connect
It connects hole, first support bar and second support bar and is fixedly connected by being successively arranged in the Quick Release screw in the two in connecting hole, fastly
The length direction that screw is torn open along guide groove is at least distributed setting two, and the connection to guarantee first support bar and second support bar is strong
Degree.
Its application method is as follows:
In use, support rod is diagonally set in inspection shaft, there is support rod one end top of elastic rubber to be set to inspection shaft
The other end of side-walls below interior penetration pipe, support rod is arranged at the well head of inspection shaft by card slot, is drawn in penetration pipe
It behind downside of the optical cable around the pulley at support rod lower end, then is bypassed by the upside of the pulley of post upper, optical cable is in addition
Support rod can also be arranged by above structure in the corresponding inspection shaft in one end, and other end be a roll of optical cable, and 3000 meters of overall length, general someone
Cable or optical cable dragger is drawn to carry out optical cable towage in other end cable laying, then using manpower, by the use of the guide device,
It is all oriented to by pulley when so that optical cable is at by the port of penetration pipe and the well head of inspection shaft, greatly reduces optical cable construction work
Stress when industry, has ensured optical cable minimum bending radius, reduces optical cable damage risk, the preferred almag of the support rod, titanium
The some materials of the lighter in weight such as alloy, steel alloy, due to support rod be the pulley of lower part is applied by optical cable it is upward
Traction force is to guarantee that its oblique balance is set in inspection shaft, and since optical cable tractive force is very big, have a people can not be pulled,
Therefore, support rod weight is only all possible if it were not for too heavy, and weight is light some using more convenient as far as possible.
Compared with prior art, the use of guide device of the present invention so that optical cable by penetration pipe port and
It is all oriented to by pulley when at the well head of inspection shaft, considerably reduces stress when optical cable construction operation, ensured optical cable minimum
Bending radius reduces damage risk, and drawing is more convenient, exerts a force smaller, for manually pulling, can effectively mitigate constructor
The labor intensity of member, and dragger is pulled, optical cable damage can be mitigated well, effectively avoid fibre core light decay from increasing, is disconnected
The occurrence of core.
