It is divided into upper layer and lower layer by horizontal inside casing；
Both ends as the frame at bottom in the isosceles trapezoid are separately connected hanging plate B, as isosceles trapezoid bottom
Four hanging plate A are uniformly connected on frame along its length, the junction of two hanging plate B and bottom is connected and is located in the middle connection two
By inside casing interconnection between the junction of a hanging plate A, i.e., be in " X " type for two inside casings of connection, and intersection point with it is described
The midpoint of horizontal inside casing is connected by connecting plate；The isosceles trapezoid bottom is located in the middle the connection punishment of two hanging plate A
Not Tong Guo inside casing connect with the both ends of the horizontal inside casing by connecting plate；
The frame is channel steel, and the inside casing is angle steel；
The horizontal inside casing is parallel with the upper bottom of isosceles trapezoid and bottom.
The advantages of the utility model and good effect are as follows:
1. four groups of releasing pulleys are suspended on same hanger by the utility model simultaneously, without adjusting coaster height, height
It is consistent, is easily adjusted each sub-conductor arc sag.
2. the utility model is reusable, avoid just scrapping using after one engineering of steel wire loop, reduces operating expenses.
3. the utility model is in the process of laying the line, coaster swing is small, and stringing passability is good, improves safety.
The synchronous installation of 4.V type insulator chain, releasing pulley and suspension, reduce workload and hitch point, improve construction
Efficiency and safety.
5. the utility model stringing, which finishes, can directly mention line, workload is greatly decreased, and conducting wire damage can be reduced.
Detailed description of the invention
Fig. 1 is the structural front view of the utility model；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is that the utility model is mounted on the structural schematic diagram on steel tower；
Wherein: 1 is frame, and 2 be inside casing, and 3 be connecting plate, and 4 be hanging plate A, and 5 be hanging plate B, and 6 be parallel hanging plate, and 7 be the first line of a couplet
Plate, 8 be releasing pulley, and 9 be V-type insulator chain, and 10 be steel tower.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figures 1 to 3, the coaster hanger of the utility model is the multistory frame structure of isosceles trapezoid, coaster hanger point
Inside for the inside casing 2 to play a supportive role in the frame 1 of isosceles trapezoid and in frame 1, the frame 1 is horizontal by one
Inside casing 2 divide for upper layer and lower layer, horizontal inside casing 2 is parallel with the upper bottom of isosceles trapezoid and bottom.
The both ends at bottom are equipped with the hanging plate B5 for connecting with V-type insulator chain 9 in isosceles trapezoid, under the isosceles trapezoid
Uniformly there are four hanging plate A4, two hanging plate A4 therein to be installed on the both ends that isosceles trapezoid is gone to the bottom for installation along its length on bottom,
It is connected releasing pulley 8 (releasing pulley 8 of the utility model is three-fold block) by parallel hanging plate 6 on each hanging plate A4, four
A releasing pulley 8 is contour to be hung in coaster hanger.Hanging plate B5 is respectively welded in the both ends of frame 1 as bottom in isosceles trapezoid,
As four hanging plate A4 of uniform welding along its length on the frame 1 of isosceles trapezoid bottom, the weld of two hanging plate B5 is welded
Two by 2 cross weld of inside casing between the weld of two hanging plate A4 of welding, i.e., for connection are located in the middle with bottom
Inside casing 2 is in " X " type, and the midpoint of intersection point and horizontal inside casing 2 is welded by connecting plate 3.Isosceles trapezoid bottom is located in the middle
The weld of two hanging plate A4 passes through inside casing 2 respectively and the both ends of horizontal inside casing 2 are welded by connecting plate 3.The utility model
Frame 1 be channel steel, inside casing 2 be angle steel.
The assembly and disassembly methods of the utility model are as follows:
When installation, the upper connective plate 7 of four groups of releasing pulleys 8 is passed through into parallel hanging plate 6 and four extensions on isosceles trapezoid bottom
Plate A4 is separately connected, and is suspended on four groups of releasing pulleys 8 are contour in coaster hanger；Then, by the one of two groups of V-type insulator chains 9
End is connect with the hanging plate B5 at bottom both ends in isosceles trapezoid；The another of V-type insulator chain 9 is connected using two sets of motor-driven grinding mill wirerope
End, wirerope, by being twisted traction enhancement to setting position, complete four after connecting with steel tower 10 by the promotion coaster on steel tower 10
The suspension of group releasing pulley 8；This installation process is more convenient.
During spreading conducting wire, four groups of releasing pulleys 8 are contour and uniform force, when limp passes through releasing pulley 8,
Coaster hanger is stable, reliable, and passability is good.
When disassembly, in tangent tower attachment installation process, lifts conducting wire with line lifter first, drawn using motor-driven grinding mill
Control, releasing pulley 8 is unlocked with coaster hanger one by one and let-down is to ground, then will with flexible nylon suspender belt and Lever Blocks
V-type insulator chain 9 is fixed, and is adjusted to required position, unlocks coaster hanger and V-type insulator chain 9 using motor-driven grinding mill control
Connecting portion, then put down coaster hanger；Finally, completing the peace of wire clamp yoke plate, wire clamp under the cooperation of Lever Blocks
The fixation of dress and conducting wire.The demolishing process of entire coaster hanger is simple, and wire clamp yoke plate can be quickly and smoothly installed in place.
It is convenient in order to simplify coaster arrangement and hang since the every pole of steel tower will hang the releasing pulley 8 of four groups of three-wheels
Subsequent Construction of Tension Stringing and attachment installation operation, the utility model use 4 × " one leads 2 " modes to eight division large-section leads
Pulley suspension mode is analyzed and has been improved, and existing V-type insulator chain and fitting are made full use of, and develops four groups of three-wheels
Wires-erecting pulley hanger, the hanger releasing pulley of four groups of three-wheels being suspended on simultaneously in same coaster hanger, can solve well
Certainly using deficiency existing for independent suspension coaster mode, to reduce pulley suspension workload, and it is contour, flat to reach releasing pulley
Positive purpose improves stringing quality, construction efficiency and safety, reduces construction cost.
