Abstract
This utility model relates to Great span pulley suspension device, it is characterized in that: by two Z 110220 right angles link plate (1), Great span releasing pulley suspender (2), Great span 5 wheel line tackle (3) is constituted, its link plate (1a) lower end, Z 110220 right angle is connected with Great span releasing pulley suspender (2), Great span releasing pulley suspender (2) lower end connects the 2nd Z 110220 right angle link plate (1b), 2nd link plate (1b) bottom, Z 110220 right angle is connected with Great span 5 wheel line tackle (3), the beneficial effects of the utility model are: reduce limp by impact load to coaster during coaster, reduce the fault rate of coaster.
Description
Technical field
This utility model relates to a kind of that can be widely used in Great span Poling Construction use, a kind of safe and reliable, satisfied
The pulley suspension device of coaster height vertical load, HI high impact feature in Great span Poling Construction.
Background technology
My company is responsible for the Ling Zhou-Shaoxing ± 800kV extra high voltage direct current transmission line engineering the Changjiang river Great span bid section of construction
Wire uses 6 × JLHA1/G4A-640/290 extra-heavy aluminium alloy stranded conductor, uses 2 × 2 to lead 3 showing and placing of the tension and lead in Poling Construction
Line.Owing to crossover tower suspension string uses 2 × 4 insulator chain structures.During spreading conducting wire, first, it is considered to pulley suspension
Match with suspension string structure；Second, it is considered to meet wire vertical load intensity；3rd, unfold during meeting unwrapping wire and led
The unbalanced moments that coaster is produced by line.Therefore coaster needs to be connected to become an entirety with 2 × 4 insulator chains.The most sliding
Car hang is coaster and 2 × 4 insulator chains individually connect after 2 channel-section steels are installed on coaster coaster are rigidly connected into
One entirety, not only reduces coaster and by intensity during coaster, causes cunning along degree of freedom on line direction, increase stringing walking plate
Car damages.Company technique team, by the analysis to coaster damage situations of the conventional Great span wire winding pulley suspension mode, determines
Make by oneself and develop novel Great span device for suspending line tackles.
Utility model content
This utility model relates to one and can be widely used in Great span Poling Construction, it is achieved reduce the skew of whole suspension string
Amount, reduces the limp vertical load to coaster, reduces limp by impact load to coaster during coaster, reduces the fault of coaster
The pulley suspension device of rate.
This utility model is mainly characterized by: by two Z-110220 right angle link plates, Great span releasing pulley suspender, Great span
5 wheel line tackles are constituted, and its link plate lower end, Z-110220 right angle is connected with Great span releasing pulley suspender, Great span unwrapping wire
Coaster suspender lower end connects the 2nd Z-110220 right angle link plate, and the 2nd link plate bottom, Z-110220 right angle and Great span 5 take turns unwrapping wire
Coaster is connected.
The beneficial effects of the utility model are: the side-play amount of whole suspension string during can being substantially reduced unwrapping wire, subtract
The little limp vertical load to coaster, reduces limp by impact load to coaster during coaster, reduces the fault rate of coaster.
Accompanying drawing explanation
Fig. 1 is this utility model product structure schematic diagram.
Detailed description of the invention
By detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings
As shown in Figure 1: Great span pulley suspension device, by two Z-110220 right angle link plates 1, Great span releasing pulley suspender
2, Great span 5 wheel line tackle 3 is constituted, its link plate 1a lower end, Z-110220 right angle and Great span releasing pulley suspender 2 phase
Even, Great span releasing pulley suspender 2 lower end connects the 2nd Z-110220 right angle link plate 1b, at the bottom of the 2nd Z-110220 right angle link plate 1b
End is connected with Great span 5 wheel line tackle 3.
Use a Z-110220 right angle link plate 1a by Great span device for suspending line tackles and 2 × 4 overhanging golden tool strings
Being connected, using Great span releasing pulley suspender 2 to be connected by 2 × 4 overhanging golden tool strings becomes an entirety, uses the 2nd Z-
Great span releasing pulley suspender 2 is connected by 110220 right angle link plate 1b with Great span 5 wheel line tackle 4, makes 5 wheel line tackles 4
Degree of freedom is being had along line direction.
During large crossing projects unwrapping wire, after limp contacts with coaster, single coaster has in fair line road lead
Degree of freedom, can be substantially reduced the side-play amount of whole suspension string, reduces the limp vertical load to coaster, reduces limp by sliding
Impact load to coaster during car, reduces the fault rate of coaster.
