Abstract
In the prior art, since a traction part is greatly influenced by the frictional resistance generated between a power transmission wire and a spanning frame, the intertwining phenomenon of a guide rope and a stay wire and the shifting phenomenon of a pulley under the effect of the wind power during the guiding process of the stay wire often occur. When it occurs, the pulley is hard to move. Meanwhile, the power transmission wire can only be moved by overcoming the frictional resistance between the power transmission wire and the spanning frame, with the presence of the intertwining of the guide rope and the stay wire and the shifting of the pulley. Therefore, the power transmission wire is easily blocked. As a result, the construction progress is influenced and the maintenance workload is increased. Meanwhile, the construction cost is also increased. The utility model provides an anti-galloping stringing spanning frame, wherein two rows of grooved pulleys are connected in parallel to complete the wire installation. Due to the adoption of the spanning frame of the above structure, the occurrence of pulley shifting phenomena is obviously reduced.
Description
Technical field
The utility model relates to a kind of crossing frame of the use that erects power transmission lines.
Background technology
Due to transmission pressure, particularly the quality of high voltage electricity transmission conductive wire itself is just larger, and there is larger span for adjacent two steel towers that support transmission pressure, barrier simultaneously that exist electrified body, crops, trees, river, road, building and structures etc. to be crossed between adjacent two steel towers, so, set up or dismantle transmission pressure and be a complexity and difficult engineering.
In prior art, setting up or dismantle transmission pressure conventionally adopts and is arranged on the guide rope between adjacent two steel towers and is suspended on guide rope and by the coaster of bracing wire control, and for avoid transmission pressure and ground or with the above-mentioned crossing frame being contacted by across obstacle and insulation net, crossing frame is wherein led to the frame structure of being made up of the aluminium alloy of steel alloy or lighter weight.Due to needs set up or the transmission pressure that is removed under the traction of coaster, to between adjacent two steel towers, move, and in the process moving at transmission pressure, to be supported and slippage thereon by crossing frame, as can be seen here, crossing frame is not only being carried the weight of transmission pressure, also and between transmission pressure produce sliding friction simultaneously, so, crossing frame is firm in any case is is also easily worn and torn by the larger frictional force that transmission pressure produced of slippage, old transmission pressure is particularly removed, because its surface is similar to zigzag tip, more easily make apart from more frame damage, in addition, frictional resistance between transmission pressure and crossing frame also can produce considerable influence to traction element, because of guide rope and coaster, and bracing wire is subject to the effect of wind-force in the air at height, often there will be the phenomenon such as guide rope and guy winding and coaster skew, after this phenomenon occurs, coaster moves more difficult, and the frictional resistance that guide rope and guy winding and coaster also need to overcome between transmission pressure and crossing frame under shift state could move transmission pressure, be easy to cause the phenomenons such as transmission pressure stagnation, and then affect construction progress and increase the operations such as maintenance capacity, its construction cost obviously improves.
Due to needs set up or the transmission pressure that is removed under the traction of pulley, to between adjacent two steel towers, move, because of guide rope and pulley, and bracing wire is subject to the effect of wind-force in the air at height, can cause pulley to reverse, if pulley can not automatically be adjusted direction, after pulley reverses, there is wrapping phenomena in guide rope and bracing wire meeting, after this phenomenon occurs, transmission pressure on mobile pulley is very difficult, particularly, in the situation that pulley windup-degree is larger, can cause guide wire wide-angle to be wound around and wearing and tearing, also be difficult to traction transmission pressure simultaneously.Another problem is; because of in the process of traction transmission pressure; it is mobile that transmission pressure often there will be jump or fluctuation-type on pulley; and this move mode can increase the resistance of traction equally; even if pulley is not in the situation that twisting; its tractive resistance is also very large, can bring certain difficulty to normal construction.
The name of No. 201260047Y bulletin of Chinese patent is called " asymmetric pulley block " and provides a solution.This pulley block comprises link plate and support, and the pulley being limited by support, although can reduce frictional resistance by the mode of rolling friction between this pulley and transmission pressure, but owing to adopting and being fixedly connected with between link plate and support, pulley block is being subject to easily torsion under extraneous wind-force effect, and pulley torsion can make transmission pressure not point-blank, and then increase the resistance that draws transmission pressure; In addition, this kind of pulley block is in the time of traction transmission pressure, only have a pulley to roll and contact with transmission pressure, when transmission pressure is in distraction procedure, its fluctuation can touch framework upper, and then make to form sliding friction between itself and framework, frictional resistance can improve greatly, and to stringing, operation brings certain difficulty.
Publication No. is the crossing frame that the patent of CN102227064 A has proposed a kind of use that erects power transmission lines, the complex structure of this patent, and the stringing complexity that operates, string efficiency is not high, and the scope of application is limited.
Utility model content
For the deficiencies in the prior art, the utility model discloses a kind of stringing crossing frame of Anti-galloping.
The technical solution of the utility model is as follows:
A stringing crossing frame for Anti-galloping, it comprises support and is arranged on the link plate on support top, establishes sheave on support, establishes sheave dividing plate between sheave.
Described sheave is two rows, between every two sheaves of two rows, all establishes sheave dividing plate.
The utility model adopts two emissions grooves to take turns the mode being in parallel to carry out the installation of cable, and the crossing frame of this structure can obviously reduce the shift phenomenon of coaster, also can prevent deviating from offside of cable, for the erection construction of cable is provided convenience.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: support 1, link plate 2, sheave 3, sheave dividing plate 4.
Embodiment
A stringing crossing frame for Anti-galloping, as shown in Figure 1, it comprises support 1 and is arranged on the link plate 2 on support 1 top, establishes sheave 3 on support 1, establishes sheave dividing plate 4 between sheave 3.
Described sheave 3 is two rows, between every two sheaves 3 of two rows, all establishes sheave dividing plate 4
The utility model is provided with two emissions grooves wheels 3, can Hierarchical Mobile cable, and cable passes through from upper and lower two-layer sheave 3, is subject to stopping of sheave dividing plate 4, there will not be to deviate from and offside situation; In addition, when the utility model adopts two emissions groove wheel 3 modes that are in parallel to carry out the installation of cable, reduce because wind-force effect makes crossing frame disequilibrium and occur the probability of skew, while making to set up cable, can steadily carry out efficiently, guarantee construction schedule.
