It is guaranteed.
The technical scheme that the utility model is provided：A kind of new OCS Messenger Wire suspended structure, including the fixed bottom of suspension
Seat, Double-ear connector, suspended compound insulator, parallel hanging plate and suspension pulley, the suspension firm banking are provided with bolt hole,
It is bolted and Double-ear connector is hung vertically in suspension firm banking lower section, suspension type is connected with below Double-ear connector
Composite insulator, the upper end of parallel hanging plate is fixedly connected by bolt with the lower end of suspended compound insulator, under parallel hanging plate
End is fixedly connected with the suspension ring at the top of suspension pulley, and carrier cable is hung using suspension pulley.
Further, when the suspension firm banking is arranged on OCS under bridge, fixed using anchorage style, the suspension is solid
Floor installation is determined at steel Hang arches, is bolted and is fixed on steel Hang arch structures.
Further, the suspended compound insulator two ends use monaural structure, by monaural respectively with the ears of top
Connector is fixedly connected with the parallel hanging plate of lower section.
Further, the suspension pulley includes frame body and pulley, and suspension pulley top is provided with suspension ring, the suspension ring
Welded with suspension pulley frame body, a horizontal fixed wheel shaft on suspension pulley frame body, the pulley is fixed on wheel
On axle, suspension ring (to wheel shaft wear to vertical by wearing for upper circular hole.
Further, a diameter of 140mm of the pulley, improves gearratio when carrier cable is moved freely, and reduces load
The abrasion of rope.
Further, pin is horizontally arranged with the chassis body above pulley, carrier cable is limited to pin and pulley
Between.
The utility model carrier cable suspended structure is generally located on large span, the overbridge of low clearance and steel Hang arch structures
On, hung at most drop shot string in overhead contact line system or close at most drop shot string.
The purpose of the utility model carrier cable suspended structure is achieved in the following ways：In overbridge or the steel Hang of growing up
Overhead contact line structure minimum point is found under arch structure, and nearby situation finds suitable carrier cable suspension according to live minimum point
Structural mounting points, between two beams, the mount point of steel Hang arch structures is on the steel construction of top vertical line road for the mount point of general overbridge.
According to the height of the minimum point carrier cable for calculating, the setting height(from bottom) of the carrier cable suspended structure is determined, and then it is outstanding to improve contact net
Structure height in extension system between two anchor points improves the purpose of contact net system coefficient of elasticity, and ensures that most drop shot string is more than
300mm and electrical body insulation against ground distance.The new carrier cable suspended structure inherits soft across upper carrier cable hang
And MTU depot overhauls the advantage of the hang of contact line in storehouse, carrier cable is because of environment between ensureing two anchor points by suspension pulley
Moved freely during temperature change.
The beneficial effects of the utility model：(1) the utility model carrier cable suspended structure is arranged on two in contact net system
Between anchor point, carrier cable suspended structure only in vertical stress and smaller, will not produce shearing resistance, to original bridge structure or
Steel Hang arch structures cause secondary destruction.(2) the utility model carrier cable suspended structure combines soft across upper carrier cable suspension side
The advantage of maintenance storehouse wire hang, solves overhead contact line under overbridge of growing up, steel Hang arch structures in formula and MTU depot
Structure height is relatively low, most drop shot string≤300mm, insulation distance cannot ensure and the relatively low situation of contact net system coefficient of elasticity,
Grow up overbridge and steel Hang arch structure Train normal operations are ensure that, the reliability and security of contact net system is increased.
(3) the utility model carrier cable suspended structure employs suspension pulley suspension carrier cable, when by variation of ambient temperature, carrier cable
Can be moved freely on suspension pulley, reduce the abrasion of carrier cable, increased the reliability and security of electric railway.(4)
Traditional suspension hook is changed to suspension ring by the suspension pulley that the utility model is used, and it is changed to fixed guide pulley, it is to avoid to hold
There is catching phenomenon in power rope.
