Description
Technical field
It the utility model is related to cable and set up aid field, and in particular to a kind of electric power communication optical cable high-altitude, which is set up, to be used
Quarter block.
Background technology
Due to the particularity of power industry, communications optical cable is typically together set up with power circuit, the aerial ring of power circuit
Border is more complicated, there is the several scenes such as steel tower, steel tube tower, electric pole；Optical cable is because of its particularity, it is impossible to undue bending and folding,
Particularly set up in high-altitude corner and be easily damaged, therefore work progress is maked somebody a mere figurehead to optical cable and requires high.Electric power leads at present
Believe that optical cable sets up generally use artificial traction method or pulley traction method in high-altitude corner, wherein artificial traction method needs
Special messenger is monitored on the shaft tower of high-altitude on real-time operation and ground, it is necessary to operating personnel's quantity is more, and during traction, optical cable bears to draw
Power is bigger, unavoidably to contact the rough place in the edges such as steel tower, steel tube tower, larger frictional force be present, manually in high-altitude
Place's traction optical cable is wasted time and energy, and efficiency is very low, optical cable damage is also easily caused, in addition, when artificial traction method needs personnel long
Between work high above the ground, great potential safety hazard be present；And on the corner optical cable is drawn by pulley, it can effectively avoid optical cable
It is time saving and energy saving with the friction at rough place, the quantity of operating personnel on shaft tower and ground can also be reduced, reduces operating personnel's
Potential safety hazard, but prior art is generally using single pulley as shown in Figure 3, folder of the optical cable from the sagging formation in pulley both sides
Angle is smaller, is easily damaged, therefore operation field is more still constructed using artificial traction method.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of electric power communication optical cable high-altitude erection quarter block, can
Set up with to solve existing electric power communication optical cable high-altitude and drawn using single pulley, the problem of causing optical cable to be easily damaged.
The utility model is achieved through the following technical solutions：
A kind of electric power communication optical cable high-altitude erection quarter block, including bottom plate, anchor ear connection is provided with the bottom plate
Hole, the bottom plate one side are connected with first support and second support side by side, first support and second support the top difference
First connecting rod and second connecting rod are connected with by first rotating shaft and the second axis of rotation, the first connecting rod and second connecting rod it is outer
End is rotatably connected to first pulley and second pulley by the first wheel shaft and the second wheel shaft respectively, is fixed on the second connecting rod
The locating support of oriented first connecting rod extension is connected, is provided with multiple positioning holes on the locating support, on the first connecting rod
It is connected with the locating pin through positioning hole.
Further scheme of the present utility model is that the anchor ear connecting hole includes first through hole and the second through hole.
Further scheme of the present utility model is that the first support and second support are in isosceles triangle.
Further scheme of the present utility model is that the locating support is curved.
Further scheme of the present utility model is that the line of arc is respectively equipped with the middle part of the first pulley and second pulley
Groove.
The utility model compared with prior art the advantages of be：
Optical cable is from first pulley and second pulley across part of the increase optical cable between first pulley and second pulley
With being caused respectively from the angle between the part that first pulley and second pulley both sides hang down, effectively reduction optical cable by undue bending
The risk of damage, and the distance between first pulley and second pulley, angle is adjustable, adapts to the optical cable installation of different size,
Adaptability is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is pulley structure schematic diagram.
Fig. 3 is existing pulley use state reference chart.
Embodiment
A kind of electric power communication optical cable high-altitude erection quarter block as shown in Figure 1, including bottom plate 14, on the bottom plate 14
The anchor ear connecting hole being provided with including the through hole 16 of first through hole 15 and second, it is easy to circular connection, triangle or other shapes
The anchor ear of shape, to adapt to different scenes, the one side of bottom plate 14 is connected with the first support 12 in isosceles triangle side by side
With second support 13, first support 12 and second support 13 top is rotated by the rotating shaft 11 of first rotating shaft 10 and second respectively
First connecting rod 5 and second connecting rod 6 are connected with, the outer end of the first connecting rod 5 and second connecting rod 6 passes through the first wheel shaft 3 respectively
First pulley 1 and second pulley 2, the middle part difference of the first pulley 1 and second pulley 2 are rotatably connected to the second wheel shaft 4
Wire casing 18 provided with arc, the locating support 9 for the arc that oriented first connecting rod 5 extends, institute are fixedly connected with the second connecting rod 6
State and multiple positioning holes 8 are provided with locating support 9, the locating pin 7 through positioning hole 8 is connected with the first connecting rod 5.
During construction, the first positioning hole 8 passed through according to the specification of set up optical cable regulation locating pin 7, make the He of first pulley 1
The spacing of second pulley 2 adapts to optical cable, is then fixed bottom plate 14 in place from suitable anchor ear, then by optical cable 17
