Description

A kind of 10KV distribution line stringing optical cable crossover device
Technical field
The present invention relates to a kind of optical cable crossover device, more specifically, it relates to a kind of 10KV distribution line stringing optical cable crossover device.
Background technology
In the erection of present 10KV distribution line, the many employings of crossing construction operation such as optical cable are set up crossing frame or are directly used that rope is sliding to be crossed.Set up crossing frame and the sliding shortcoming of crossing existence of rope: the time of setting up of crossing frame is long, and operation is many, wastes time and energy.In 10KV wire erection process more intersection for the optical cable such as low voltage voltage circuit communication be main, the practical significance setting up crossing frame is not obvious; Rope is the cunning shortcoming of crossing directly: slidingly tide over the rear structure to span lines such as communication cables and damage and damage, and also can damage wire external insulation and wire rod after wire passes through.The requirement that applicable safety is carried out production strictly in line with rules and regulations cannot be met.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of destruction avoiding damage and the wire self caused span lines such as optical cables is provided, improves the operating efficiency of crossing construction during wire erection and reduce the 10KV distribution line stringing optical cable crossover device of activity duration.
The object of the invention is to be achieved through the following technical solutions.This 10KV distribution line stringing optical cable crossover device, comprise lead, gravity rope hangs down, cross over pulley, hook stick, weight release lever, dropout spring, described lead is located to be crossed on pulley, cross over pulley and connect weight release lever, the end of described weight release lever is provided with the stay hook hung down for catching on gravity rope.Described weight release lever is made up of upper upper arm and lower upper arm, and the coupling part of upper upper arm and lower upper arm is rotating shaft and is provided with dropout spring.The height lock pin holes that described hook stick is also provided with flexible adjusting lever and matches.The described weight release lever rope be provided with for spacing rope hangs down slideway.Described gravity rope hangs down and is provided with the dropout bayonet socket with stay hook cooperation.
As preferably: described leap pulley is fixed by pulley set bolt.
The invention has the beneficial effects as follows: the anti-wire of the lead on crossover device is not jumped out and conveniently gone out device lift-off in distraction procedure from crossover device.Hook stick is that more piece assembly type is convenient for carrying and installs.Terminal bar adopts telescopic round to lock, and highly regulates freely, solid and reliable.Can Fast Installation to set up leads span, carry easy for installation on the optical cables such as various communication, broadcasting and TV, electric power and low-voltage circuit.Optical cable and aerial condutor can be effectively protected not to be damaged during leads span optical cable.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.Although the present invention will be described in conjunction with preferred embodiment, should know, and not represent and limit the invention in described embodiment.On the contrary, the present invention will contain can be included in attached claims limit scope of the present invention in alternative, modified model and equivalent.
See shown in Fig. 1 to Fig. 7,10KV distribution line stringing optical cable crossover device, comprise lead 1, gravity rope hang down 2, cross over pulley 3, hook stick 7, weight release lever 8, dropout spring 9, described lead 1 is located to be crossed on pulley 3, cross over pulley 3 and connect weight release lever 8, the end of described weight release lever 8 be provided with for catch on gravity rope hang down 2 stay hook.Described weight release lever 8 is made up of upper upper arm 15 and lower upper arm 16, and the coupling part of upper upper arm 15 and lower upper arm 16 is rotating shaft and is provided with dropout spring 9.The height lock pin holes 11 that described hook stick 7 is also provided with flexible adjusting lever 10 and matches.Described weight release lever 8 rope be provided with for spacing rope 13 hangs down slideway 4.Described leap pulley 3 is fixed by pulley set bolt 6.Described gravity rope hang down 2 be provided with stay hook coordinate dropout bayonet socket 14.
10KV construction of line optical cable crossover device utilizes to arrange on optical cable 12 to cross over pulley 3, and height highly can carry out free adjustment according to optical cable 12; Realize the protection of optical cable 12 and lead body and realize leads span construction.
Crossing over optical cable device directly hangs on optical cable 12, and optical cable 12 body touches the release lever 8 that heavily hangs down, and gravity rope hangs down 2 with rope 13 from the other end freely falling body of optical cable 12 to ground; Hook stick 7 final section locks by the height according to optical cable 12, makes the weight of wire after leap all on straddle tool, reduces the applied force to optical cable 12.The conducting wire end crossed over is connected with the rope 13 of instrument, pulls gravity rope vertical 2 that rope 13 was drawn leap pulley 3.The anti-rope 13 of lead 1 crossed on pulley 3 is jumped out in distraction procedure from leap pulley 3.Hook stick 7 is convenient for carrying and installs for more piece assembly type.Flexible adjusting lever 10 adopts telescopic round to lock, and highly regulates freely, solid and reliable.
As shown in Figure 5, A is spring tension direction, and B is the optical cable touching direction of motion.Figure 6 shows that state when weight release lever 8 is normal, now, upper upper arm 15 does not touch by the optical cable 12 crossed over, and the gravity rope in lower upper arm 16 hangs down and 2 is placed in rope and hangs down in slideway 4, gravity rope hang down 2 dropout bayonet socket 14 and stay hook connect.Figure 7 shows that the upper upper arm 15 of weight release lever 8 touches by the optical cable 12 crossed over, now, lower upper arm 16 moves along with upper moving up of upper arm 15, the stay hook of lower upper arm 16 throw off gravity rope hang down 2 dropout bayonet socket 14, gravity rope vertical 2 lands due to gravity, drives rope 13 to cross over by the optical cable 12 crossed over.
